What are the common faults of Paper Sheeting Machine?

Common faults of Paper Sheeting Machine mainly include the following points, cutting problems, winding problems, running faults, and operating faults. Let's take a closer look.

Cutting quality problems

Uneven paper cutting:

Blade problems: Blade wear, bluntness or loose installation may cause uneven cutting surface, burrs, etc., and the blade needs to be replaced or reinstalled in time

Improper adjustment of the paper feed positioning baffle: If the relative position of the paper feed positioning baffle and the blade is inaccurate, the paper will deviate when entering the cutting area, resulting in uneven cutting. The position of the positioning baffle needs to be readjusted

Paper guide wheel problem: The paper guide wheel is not flexible, the surface is worn or improperly adjusted, which will affect the paper feeding and cutting accuracy. The state of the paper guide wheel should be checked and adjusted or replaced. Inaccurate cutting length

Meter wheel failure: The meter wheel is worn, the count is inaccurate, or the contact with the feeding rubber roller is poor, which will cause errors in the cutting length. You can check Check the wear of the meter wheel and ensure that it is in close contact with the feeding rubber roller. Replace the meter wheel if necessary.

Transmission system problems: loose or missing teeth of the synchronous belt, severe wear and vibration of the transmission shaft bearing, loose gears of the feeding belt knife, etc., will affect the accuracy of the cutting length. The transmission system needs to be inspected and maintained, and the worn parts need to be replaced.

Encoder failure: If the encoder is loose, stuck or damaged, the control signal of the cutting length will be inaccurate. The connection and working status of the encoder should be checked and replaced in time if there is any problem.

Reeling problem

Uneven reeling

Paper core problem: The inner diameter of the paper core does not match the reel, the paper core is deformed or the surface is uneven, which will cause the paper to be unable to be evenly wound on the paper core during reeling, resulting in uneven reeling. It is necessary to replace the appropriate paper core.

Uneven reeling tension: Too much or too little reeling tension, and inconsistent tension at both ends of the reel will cause the paper to deviate during the reeling process. The reeling tension should be reasonably adjusted according to the material and thickness of the paper, and the pressure at both ends of the reel should be balanced.

Equipment component failure: If the winding roller is worn, deformed or the pressure is uneven, it will also affect the winding quality. The state of the winding roller needs to be checked and adjusted or replaced.

Wrinkling of winding materials

Insufficient winding tension: Insufficient tension will prevent the paper from fitting tightly during winding, resulting in wrinkling. The winding tension needs to be appropriately increased.

Roller problem: Insufficient pressure or improper position of the winding roller will not effectively compact the paper, which will also cause wrinkling. The pressure and position of the roller should be adjusted to ensure that the paper is fully compacted during the winding process.

Problems with the paper itself: Excessive moisture content and uneven texture of the paper may also cause wrinkling during winding. At this time, the paper needs to be pre-treated or replaced with qualified paper.

Operation failure

High machine vibration and noise:

Loose parts: Loose fixing bolts, nuts, etc. of the equipment will cause vibration and noise during operation of the machine. All fixing parts should be checked and tightened.

Bearing damage: Wear or damage of transmission bearings, support bearings, etc. will cause abnormal vibration and noise of the machine. The damaged bearings need to be replaced in time.

Poor gear meshing: Gear wear, missing teeth or excessive meshing clearance will cause the machine to run unsteadily, generate vibration and noise. The gear status should be checked and adjusted or replaced.

Sudden equipment shutdown:

Power failure: Unstable power supply voltage, phase loss or short circuit, etc., will cause the equipment to shut down suddenly. The power supply line and electrical components should be checked to ensure normal power supply.

Overload protection: If the load of the equipment is too large during operation and exceeds the carrying capacity of the motor or other components, the overload protection device will be activated and the equipment will shut down. At this time, it is necessary to check the load of the equipment and eliminate the overload fault.

Fault alarm: When the control system of the equipment detects a fault signal, it will automatically shut down and issue an alarm prompt. The cause of the fault should be found according to the alarm information and corresponding treatment should be carried out.

Other issues

Paper static electricity problem: In a dry environment, paper is prone to static electricity, which absorbs dust and impurities, affecting the cutting quality and working environment. This can be solved by installing an electrostatic eliminator, increasing the humidity in the workshop, etc.

Insufficient lubrication: The various components of the equipment need to be lubricated regularly. If the lubrication is insufficient, it will cause increased wear of the components, increased operating resistance, and even failure. Lubricating oil should be added regularly according to the requirements of the equipment

Control system failure: Program errors, improper parameter settings, sensor failures, etc. in the control system will affect the normal operation and control accuracy of the equipment. The control system needs to be checked and debugged, and the faulty components need to be repaired or replaced.

Summary

Common faults of Paper Sheeting Machine involve many aspects, and operators need to have rich experience and professional knowledge to diagnose and eliminate them. At the same time, regular maintenance and care are also important measures to prevent failures.
