The twisting machine is a piece of equipment widely used in wire production and processing. However, in actual use, some common faults may occur due to various reasons. This article will analyze the common faults of twisting machines and their repair methods.
1. Host startup abnormality
When the host starts abnormally, phenomena such as flashing and shedding will usually occur. In addition to hardware problems such as power supply, the main reason for this situation is the failure of related accessories in the machine. The solution is to first check whether the accessories are firmly connected and whether the power supply is normal, and see where there are looseness, aging, etc., and then check the status of each accessory one by one, such as cables, wiring, motors, travel switches, etc., and repair or replace them.
2. Film feeder failure
In the past, the film feeder required the staff to manually adjust the transmission wheel until the pressure of the guide wheel reached a balance. However, because repeated adjustments by the staff would cause wheel wear, it is recommended to use an electronically controlled film feeder. If the film feeder fails, there may be a problem with the circuit or mechanical structure. The solution is to check the power interference, check the spacing between the film supply wheel and the guide wheel, whether the spacing is equal, and whether the wheel is parallel to the axis. If there is a problem, it must be adjusted or replaced.
3. Manual turning tool holder failure
The manual turning tool holder is an important component that rotates synchronously with the spindle to complete the turning work. If the manual turning tool holder fails, it is usually due to the manual turning tool holder twisting the screw or insufficient spring elasticity, the turning tool is not tight, and the contact with the coil is not compacted. The solution is to replace the screws and springs and reinstall the cutter.
4. Spindle transmission chain failure
The spindle transmission chain is one of the core components of the twisting machine and is mainly responsible for transmitting speed and torque. If a failure occurs, it is mainly due to a loose drive chain or worn sprocket. The solution is to replace worn parts or the entire transmission chain to ensure that the gap between the sprocket and the transmission chain is within the specified range to prevent loosening and misalignment.
5. Cover faults on and off the line step by step
Gradual upper and lower line coverage is one of the key processes of the twisting machine, and it is also a difficult process of the twisting machine. If a fault occurs, it is usually caused by a fault in the internal mechanical structure of the film head, loose cable plug, uneven pressure on the film supply wheel, etc. Solutions include checking whether each accessory is secure and adjusting the mechanical structure inside the membrane head to achieve a better state.
6. Vibration of the whole machine
During the use of the twisting machine, the whole machine sometimes vibrates. This may be caused by uneven coverage of the upper and lower threads, eccentricity of the main shaft, excessive tightness of the transmission chain, or high-speed swing of the sliding chain. Solutions include adjusting the upper and lower line coverage pressure step by step, checking whether the spindle is eccentric, adjusting the spindle tightness, checking the status of the transmission chain, etc.
The new twisting machine has the advantages of a variety of process combinations, which can meet the needs of different processing and production. It also has many advantages such as high speed, high efficiency, low energy consumption, and environmental protection. However, during use, you still need to pay attention to the operation and maintenance of the equipment and repair faults in time to ensure production efficiency and quality.
