Ensure that the material can be evenly transported by adjusting the tension of the equipment and the conveyor belt.
Use automated measurement and adjustment systems to ensure dimensional consistency during the production process and ensure high consistency of product quality.
Point 4: Material jamming or jamming
Problem description: The non-woven material is jammed or blocked inside the machine, which hinders the production process.
Possible factors:
Non-woven materials are curled or uneven, which may cause products to get stuck inside.
If there is a problem with the conveyor belt or feeding system, the material cannot be effectively transferred.
There is dust or other debris in the equipment or feeding area.
Countermeasures:
Equipment should be cleaned regularly, especially the feeding system and conveyor belt.
Inspect the feeding path of non-woven materials and make appropriate adjustments to ensure that these materials are flat and not bent.
Periodically maintain and inspect components such as conveyor belts and rollers to ensure that there are no foreign objects causing blockages.
Item 5: The accuracy of hole cutting needs to be improved
Problem description: The hole placement of the handbag is not accurate enough, which may cause deviation in the hand placement or irregularities in the overall appearance.
Possible factors:
The equipment configuration of the hole may be wrong, or it may cause the mold to be worn.
Because the speed of the machine conveyor belt is not stable enough, this will cause the punching position to shift.
Coping strategy handling:
In order to ensure the alignment of the mold, it is necessary to adjust the accuracy of the punching device.
Ensure that the conveyor belt speed of the machine is calibrated to maintain data stability.
Check and replace the punching mold regularly to confirm whether they are worn or deformed.
6The mechanical system is unstable or malfunctioning
The description of the problem is as follows: When the machine suddenly stops running or erratically operates, it may cause production activities to be interrupted.
Possible factors:
Failures in the power system can be divided into multiple categories, including but not limited to power fluctuations, control device failures, and short circuits in wires.
When there is a failure in the transmission system, such as motors, gears, and chains, problems will occur.
When there is a failure in the pneumatic system, such as reduced air pressure and cylinder blockage.
Response strategy:
Inspect the electrical system and ensure that key components such as power supply, control module and wires are functioning properly.
Check and lubricate the transmission system to ensure that components including motors, gears and chains can operate smoothly.
Check the air pressure and cylinders in the pneumatic system to confirm their normal operation, and repair or replace damaged parts if necessary.
Article 7 The equipment vibrates or the noise level exceeds the standard
Describe the problem: During the operation of the equipment, if abnormal vibration and noise occur, it may reduce production efficiency or cause damage to the machine.
Possible factors:
Due to the instability or loose fastening of machine parts, the operation of the equipment has stability problems.
The transmission system shows signs of wear or uneven load.
Due to insufficient lubrication between components, it is easy to cause noise problems caused by mutual friction.
Response strategy:
Check whether the mechanical parts are tightened regularly to ensure that each part is stable and fixed.
Carefully check the transmission system to ensure that each part is evenly stressed. If necessary, it may need to be adjusted or replaced.
Add an appropriate amount of lubricant to all movable components to significantly reduce the occurrence of friction.
Item 8: Excessive temperature of the equipment
Problem background description: The electrical part or heat sealing area of ​​the machine overheats, causing the production process to stagnate or the equipment to be damaged.
Possible factors:
Excessive heat sealing head or motor load will cause the temperature to rise after a long delay.
Due to the failure or insufficiency of the cooling system, it is not able to cool down quickly.
Response strategy handling:
Regularly check the cooling system to ensure its normal operation and ensure that the cooling system is cleaned in time.
Avoid spending a lot of time on high-load operation for mechanical equipment when necessary, and provide appropriate rest periods when necessary.
The working condition of the motor and heat sealing head needs to be checked regularly to prevent it from being too hot.
Item 9: Unreasonable waste of resources
Problem overview: In the production process, a large amount of waste and raw materials are generated, which directly leads to a decrease in production efficiency and cost.
Possible factors:
Because of inaccurate cutting or supply of materials used, this leads to waste of resources.
Poor adjustment of equipment makes the material not fully applied.
Response strategy:
Adjust the material delivery plan to ensure the accurate transmission of non-woven products.
Optimizing cutting and material utilization with the help of automatic adjustment system helps to reduce resource waste.
