Overview: In order to reduce the probability of entanglement, damage, and damage of rubber rolls and rings in spinning production, this paper elaborates on the causes of local or individual entanglement, damage, and damage of rubber rolls. It specifically analyzes the treatment methods of rubber roll entanglement, oil filling of rubber roll bearings and roll bearings, cleaning of stretching and winding components, and the impact of workshop rubber roll replacement methods on the quality of rubber rolls, as well as the harmfulness of rubber roll damage, rupture, scratches, scratches, cracks, pollution, damage, and entanglement. Individual or partial damage to the roll is caused by human factors or management factors, and is the main cause of harm to the coefficient of variation and defects of cotton yarn. Attention should be paid to detail management in the spinning workshop, standardized operations should be formulated, centralized replacement or manual single spindle processing of the winding roll should be carried out, and the oiling operation method of roll bearings should be adopted correctly. Reasonable workshop scale units should be established, and the cleaning frequency of the stretching and winding part should be determined based on the spinning variety and production environment. This is the key to reducing roll damage and ensuring spinning quality.
1. Rove has high twist.
2. Insufficient pressure on the spinning frame.
3. The size of the spacing block is not suitable.
4. The traction in the back area is too small.
5. Laura has cotton wax.
6. Non joint of coarse yarn causes double stranded coarse yarn.
7. The workshop has high humidity wrapped around rollers, and low humidity wrapped around leather rolls, please keep an eye on them at all times.
8. The lower cutting rod and the upper and lower leather circles are not rotating properly due to the accumulation of flowers.
9. The leather ring, spring clip, and coarse yarn end are stuck due to ineffective rotation.
10. The roll is entangled and blocked by the lathe worker's untimely patrol, resulting in long-term wear and damage to the roll.
The damaged rough yarn roll shown in the picture was caused by a violation of regulations by frontline employees. During the handling of rough yarn breakage, the roll was wrapped in cotton, the velvet sleeve was jammed, and the bundle was not placed in place, resulting in pressing under the roll and damaging it after driving.
Summarize prevention measures; 1. Regular theoretical and practical training for operation operators, and correct operation methods. 2. Before driving, carefully inspect and confirm the accuracy before driving to avoid equipment damage caused by human factors.
The damage to the bottom roll is due to insufficient lubricating grease (oil) during regular maintenance, resulting in a lack of oil in the roll bearing cap and inability to rotate normally, leading to damage to the roll.
Summarize prevention measures; 1. When wiping the car, be sure to add lubricating oil in place (set a refueling cycle, once a week). 2. The operation operator shall patrol and promptly detect and provide feedback to the team leader, and contact the equipment for replacement. 3. Provide more training to employees on a regular basis to prevent such damage incidents from happening again.
The picture of the combing and stretching area below is due to the cotton entanglement of the leather roll, the lack of photoelectric sensitivity, and the failure to stop the car in a timely manner. The car blocking worker did not clean the car in a timely manner, and the car blocking worker did not patrol in a timely manner, resulting in damage to the suction port blockage.
Summarize prevention measures;
1. Electrical appliances should have a monthly photoelectric inspection cycle to avoid damage caused by poor photoelectric performance.
The specialized parts were not coated with anti winding agent and not exposed to light after grinding.
3. The car blocking worker should clean it in a timely manner, patrol more during the shift, break the head in the stretching area multiple times, and promptly contact the equipment for maintenance of the air intake.
4. Multiple vehicles have entangled cotton in the stretching roll or in the area. Observe the temperature and humidity changes in the workshop and promptly contact the air conditioning worker.
The damage to the stretching roll of the strip is related to the damage caused by entering hard objects.
Summarize prevention measures;
When wiping the equipment, clean the small screws between the machine and the ground to avoid leaving any damage to the equipment.
During the operation of the operator's patrol, pay more attention to observation. If any looseness is found in the guide frame, contact the team leader in a timely manner and tighten it.
Operators should avoid human damage or falling to the ground during cleaning.
The damage of the combing separation roll is related to the blocking worker, the cleaning cotton collector is not placed in place, the top comb is not placed in place, the buckle is not fastened, the screws are loose, and the cotton black cover is used for a long time, resulting in loose pins, which is also related.
Summarize prevention measures;
1. When cleaning, the cylinder is in a closed state to prevent foreign objects from entering and damaging the equipment.
2. When cleaning, the top comb should be installed in place, the buckle should be securely fastened, and the cotton collector should be placed in place. If the cotton black cover is loose, it should be reported to the equipment for repair in a timely manner. When driving, it is necessary to slow down and observe for no abnormalities before clicking fast.
3. Provide on-site demonstrations and theoretical training on the operation methods of car blocking workers to avoid such incidents.
