Which to choose between a double twisting machine and a twisting machine

As a rising star in the textile industry, the proportion of double twisting machines has rapidly increased in recent years. In terms of production, the processing efficiency of the double twisting machine is relatively good. Currently, the double twisting machine used is no longer single twisting, but uses multi twisting double twisting machine equipment.From a cost perspective, the purchase cost of a double twisting machine is significantly higher than that of a double twisting machine. For enterprises that can meet the demand for single thread twisting, the twisting machine can meet the production needs. From the perspective of cost control for enterprises, there is no greater advantage in the price of double twisting machines. On the contrary, the lower price of twisting machines will be favored by more small and medium-sized enterprises.In terms of production efficiency and product quality, double twisting machines naturally have greater advantages. The current double twisting machine technology can already achieve multi twisting processing and production. For enterprises with high production requirements, they will naturally choose double twisting machines on the basis of excluding purchase costs. In digital production, the double twisting machine can reduce the number of operators by about half, achieve partial automation of production, and reduce the labor costs of enterprises in the production process.In terms of efficiency, the production efficiency of the double twisting machine is best to reach over 80%, while the production efficiency of the twisting machine far falls short of the standard. Through digital regulation, the production efficiency of the double twisting machine can approach 100%.Overall, the double twisting machine is more suitable for the development of modern textile industry, and it also has a greater advantage in production efficiency.Principles for purchasing accessories for double twisting machinesIn the process of using the double twisting machine, there are several issues that need to be paid attention to when purchasing double twisting machine accessories, as purchasers of related enterprises.Firstly, there are many types of accessories for double twisting machines. For different production times and enterprises, the related accessories will naturally vary. When purchasing, it is necessary to first determine the product size of the accessories. If for other reasons, it is not possible to clarify the accessories, it is best to directly contact the relevant production enterprises for procurement.Secondly, there may be differences in the metal materials used in the accessories of the double twisting machine. Common metal materials include alloys, stainless steel, iron, steel, etc. According to actual usage needs, suitable metal materials should be selected. In the environment of use, various metal materials will change with changes in workshop temperature and equipment temperature, and the relevant diameter will also need to be predicted in advance.Thirdly, large-scale procurement requires specialized storage, especially for some metal accessories that need to be stored in a dry environment and classified for targeted storage to avoid damage.Fourthly, the accessories of the double twisting machine need to be durable, strong anti fouling, precision assembled, not easily deformed, and will not fade. These are the qualities that procurement personnel need to control.When purchasing accessories for double twisting machines, relevant procurement personnel need to pay attention to the quality of the purchased products to ensure that the purchased accessories can be replaced and used normally.

    Analysis of the causes of abnormal noise in the double twisting machine belt

    The belt of the double twisting machine is a consumable item in the equipment. After using it for a period of time, its surface friction coefficient will be greatly reduced. At the same time, accompanied by abnormal noises from the equipment, some users may still find various abnormal noises during the normal operation of the belt. There are several reasons for the abnormal noises.1: When the length of the transmission belt reaches its critical value, its stress will be affected to a certain extent, resulting in noise.2: If the belt is not excessively stretched and within a reasonable range, and the working condition of the automatic tensioner is not abnormal, it is necessary to check whether there is any wear on the surface of the belt. If the surface of the belt is too smooth, it may cause the belt to slip due to the presence of load, and the paint on the surface of the belt pulley will peel off, resulting in various slipping situations.3: The surface of the belt contains various particle impurities of different sizes, and there may be some deviations when it is under normal transmission power.4: When the driving device driven by the auxiliary mechanism is installed improperly, the equipment will produce noise, and the friction between the belt and the bearing will increase.5: When it is difficult to rotate and the equipment makes rough and harsh noises, it is a problem with the bearings. After replacing the bearings, if the noise still appears, it is a problem with the belt tensioning device, and the belt needs to be replaced in a timely manner.6: When the double twisting machine is in an overloaded state for a long time, the belt will experience an increase in load, changes in friction, and wear.The reasons for the difficulty in braking the spindle of the double twisting machine1: The problem with the dragon beltWhen there is oil stains on the surface of the dragon belt, it will lead to a decrease in friction between components, and there will be certain difficulties in braking the spindle. The driving wheel of the dragon belt transmission slips, and loose installation of the dragon belt can also cause such situations.Solution:;After disassembling the dragon belt of the double twisting machine, it is subjected to uniform tension stretching. At the same time, the oil stains on the dragon belt need to be cleaned in a timely manner. The cleaning liquid for the dragon belt should be neutral, as acidic liquids can cause some corrosion. Light oil stains can be wiped off with a cloth.2: Motor belt slippingLong term operation can cause significant wear on the pulley on the electric motor, resulting in a smaller diameter. In the gearbox, the motor's belt may slip, which is also the reason why the spindle cannot brake properly.Solution:Belt is a consumable component that must be replaced when the spindle cannot be braked. Belt replacement needs to be carried out according to maintenance requirements, while the slipping of a flat belt is due to oil stains on the surface. Cleaning the oil stains is sufficient.3: Abnormal spindleDuring long-term use, spindles may also encounter various problems, and adjacent spindle rollers may also experience wear and tear.Solution:The abnormality of the spindle is generally not repaired, and the product is replaced directly. After the deformation and damage of the spindle's compression wheel, a new compression wheel needs to be replaced. When using it, the equipment parameters should be controlled. Multiple overloads can exacerbate the wear of the spindle.

    Procurement principles and equipment selection for double twisting machine accessorie...

    In the process of using the double twisting machine, there are several issues that need to be paid attention to when purchasing double twisting machine accessories, as purchasers of related enterprises.Firstly, there are many types of accessories for double twisting machines. For different production times and enterprises, the related accessories will naturally vary. When purchasing, it is necessary to first determine the product size of the accessories. If for other reasons, it is not possible to clarify the accessories, it is best to directly contact the relevant production enterprises for procurement.Secondly, there may be differences in the metal materials used in the accessories of the double twisting machine. Common metal materials include alloys, stainless steel, iron, steel, etc. According to actual usage needs, suitable metal materials should be selected. In the environment of use, various metal materials will change with changes in workshop temperature and equipment temperature, and the relevant diameter will also need to be predicted in advance.Thirdly, large-scale procurement requires specialized storage, especially for some metal accessories that need to be stored in a dry environment and classified for targeted storage to avoid damage.Fourthly, the accessories of the double twisting machine need to be durable, strong anti fouling, precision assembled, not easily deformed, and will not fade. These are the qualities that procurement personnel need to control.When purchasing accessories for double twisting machines, relevant procurement personnel need to pay attention to the quality of the purchased products to ensure that the purchased accessories can be replaced and used normally.Composition and Equipment Selection of Double TwisterThe common double twisting machine is mainly composed of a power part, a transmission part, and a double twisting unit. The power part mainly consists of an electric motor, an electrical box controller, an indicator, etc. The power part is a relatively core component that can control the twisting of the double twisting machine. When operating the double twisting machine, the operator also uses the operation panel for operation.The unit of double twisting includes various spindle braking devices, namely the braking device, the spindle part of the double twisting machine, the yarn winding device, and other devices of the double twisting unit. When choosing a double twisting machine, many users often only consider the parameters of the relevant electric motor, without considering the relevant products of the double twisting unit, which leads to the inability to match the purchased double twisting machine with the electric motor, resulting in noise during operation.The transmission part of the double twisting machine can be divided into belt, dragon belt, and spindle dragon belt transmission spindles. Some components of the transmission part are consumables and play a certain role in the use of the double twisting machine. In daily use of the double twisting machine, these components need to be checked regularly and replaced regularly.The composition of a double twisting machine consists of three aspects, and when choosing a double twisting machine, users also need to start from these three aspects.

    What is the reason why the double twisting machine keeps breaking threads

    What is the reason why people often break wires when using a double twisting machine? Today, we will share with you the cause analysis and solutions:1. Analysis of broken ends in double twisting machinesDuring the production process of the double twisting machine, the high or low yarn breakage rate not only directly affects the quality and production efficiency of the yarn, but also affects the labor intensity of the operators. Normally, the occurrence of yarn breakage during the production process of a double twisting machine includes the following four aspects:(1) Single spindle breakage refers to individual spindles having more breakage while other spindles are normal.(2) The whole machine has a high breakage rate when feeding large yarn into the bobbin, resulting in a smaller feeding size and a decrease in breakage;(3) The whole machine has a high breakage rate when feeding small yarn into the bobbin. As the feeding of the bobbin becomes smaller, the breakage rate increases accordingly;(4) The whole machine has a broken head C, which is high and has no significant relationship with the size of the feeding tube.2. Solutions to reduce head breakage(1) Single spindle breakagea. Check if there is any damage to the yarn channel components such as the guide nozzle and friction roller. If any, please replace it in a timely manner.b. Check if the piston, bullet head, spring, etc. in the tensioner are stuck or not flexible. If any, please replace it in a timely manner.c. Check the yarn channel components and spindles for entanglement and flying flowers. If available, please clean it promptly.d. The yarn fed into the bobbin has low strength, uneven density of the bobbin, and poor molding. Please swap with adjacent normal ingot positions and check if there is any change in the breakage situation.e. The yarn fed into the tube is biased upwards, and the spindle wing touches the yarn fed into the tube. Please adjust the merging tube.f. The yarn fed into the tube is too low, and the bottom of the ingot jar touches the yarn fed into the tube. Please adjust the merging tube.g. The transverse guide nozzle touches the winding spool. Adjust the position of the yarn guide nozzle to determine if it is appropriate. Usually, we judge based on whether the yarn guide nozzle does not touch the full cylinder.(2) Complete machine breakageMachine breakage A: Excessive yarn storage causes the machine to break, that is, when feeding large yarn into the package, the yarn storage exceeds 720 °. In this case, the yarn storage capacity can be adjusted to an appropriate range by replacing bullet heads, counterweight washers, etc. When feeding large yarn into the tube, the reasonable yarn storage should be controlled between 360 ° -720 °.Whole machine breakage B: The small storage capacity causes the whole machine breakage, that is, when feeding small yarn into the bobbin, the storage capacity is less than 90 °. In this case, the yarn storage capacity can also be adjusted to an appropriate range by replacing bullet heads, counterweight washers, etc. When feeding small yarn into the tube, the storage capacity should be controlled at: greater than 90 °.Machine breakage C: This type should be analyzed in the following ways:a. The size of the balloon is appropriate (that is, the size of the balloon is in the middle of the ingot jar and the upper edge of the balloon cover), and the yarn storage capacity is normal. In this case, there are two reasons for the high yarn breakage rate:Firstly, the overall strength of this batch of yarn is not high. The corresponding solution is to reduce the spindle speed while ensuring that the size of the balloon is appropriate and the yarn storage capacity is normal.Secondly, the coiling tension is too high. The corresponding solution is to adjust the position of the deflection roller (adjust outward) or increase the overfeeding rate (increase the overfeeding rate).b. The air ring is too small and touches the upper edge of the ingot jar. Increase the height of the balloon and increase the ingot speed. Ensure that the size of the balloon is appropriate and the yarn storage capacity is normal.c. The balloon is too large and touches the upper edge of the balloon cover. Reduce the height of the balloon and, if necessary, lower the ingot speed. Ensure that the size of the balloon is appropriate and the yarn storage capacity is normal.
