The usage method of high-speed edgeless double twisting machine mainly includes the following steps:
1、 Preparation before startup
Check equipment: Ensure that the double twisting machine is in good working condition, check whether all components are intact, especially key components such as tension adjustment device, yarn guide device, and spindle.
Cleaning equipment: Keep the equipment clean, regularly clean the yarn channel, ingot tank and other parts of the rewinding and flying flowers, to prevent affecting the quality of yarn and equipment performance.
Selection of yarn: Select suitable yarn as raw material according to production requirements to ensure that the quality of the yarn meets the standards.
2、 Power on operation
Power on: Insert the machine power cord into a power outlet, turn on the power switch, and the machine will perform a self check to detect any abnormalities in the coils and pipelines.
Set parameters: Set the speed, tension, and tightness of the machine according to the requirements of the yarn type and machine model.
Start the machine: Open the start button on the machine operation panel, and the machine will continue to start, ready to enter standby mode.
Placing yarn: Remove the yarn from the yarn rack, pass it through the yarn guide device, and ensure that the yarn channel is unobstructed. Wrap the yarn around the ingot can, ensuring that the direction of yarn rewinding is consistent with the rotation direction of the ingot can.
Adjust tension: Gradually adjust the tension of the yarn by adjusting the adjusting screw or knob on the tension device. During the adjustment process, it is necessary to closely observe the condition of the yarn to ensure that it maintains a moderate degree of tightness, avoiding yarn breakage or uneven twist caused by over tightening or over loosening.
3、 Production process
Head production operation: When starting up the head production, it is necessary to ensure that the markings on the ingot can are on the front and follow the prescribed steps for the head production operation.
Joining operation: Before joining, the foot brake must be released for a period of time (such as 1518 seconds), and at the same time, the yarn tail of the machine barrel must be pulled a distance (such as 23 meters) to ensure even twisting of the yarn before and after. When joining, it is necessary to control the interval between releasing the brake and releasing the finished yarn, and only after the yarn quality is stable can the joint be made. The quality of the joint should be good to avoid situations of excessive or insufficient twisting.
Patrol inspection: During the production process, it is important to constantly monitor the quality of the yarn and the operational status of the equipment. If abnormal yarn quality or equipment failure is found, the machine should be stopped immediately for inspection and adjustment.
Tube changing operation: When the yarn is about to run out, a tube changing operation is required. Lift the self stopping probe and yarn guide hook, remove the ingot wing, and hang the ingot wing outside the ingot can guardrail. Remove the empty tube from the ingot can, take out the tube and insert the yarn head into the ingot can, paying attention to the direction of yarn rewinding. Thread the yarn through the end eye of the ingot wing, remove a sufficient length of yarn from the barrel, then follow the prescribed steps to guide the yarn into the yarn guide hook, wrap it around the deflection roller, and finally start the ingot for twisting.
4、 Shutdown and maintenance
Shutdown operation: After production is completed, stop the machine in the prescribed order and cut off the power supply.
Cleaning equipment: Clean all components of the equipment, especially the yarn channels, ingot cans, and other areas that are prone to dust accumulation.
Maintenance: Regularly maintain the equipment, including checking the wear and tear of each component, replacing severely worn parts, cleaning up accumulated dust, etc. Keep the equipment clean and lubricated to ensure that it is in good working condition.
5、 Precautions
Safety first: When operating the double twisting machine, it is necessary to follow the safety operating procedures to avoid accidental injuries.
Gradual adjustment: When adjusting tension, the principle of gradual adjustment should be followed to avoid yarn breakage or equipment damage caused by excessive one-time adjustment.
Observing the condition of the yarn: During the production process, it is important to constantly monitor the condition of the yarn to ensure that its elasticity is moderate and the twist is uniform.
Following the above steps and precautions can ensure the normal operation of the high-speed edgeless twisting machine and improve production efficiency and product quality.
