When the stretch film packaging machine is running, the operator should stand in a safe place with a certain distance from the turntable. When the machine stops after a working process, it should be close to the machine to prevent the goods from being scattered and hurt people. If necessary, a safety isolation net should be installed (self-provided or otherwise) customized).

A few points for attention in the operation of stretch film packaging machine
1. It is forbidden to test the voltage between the DC motor control board of the wrapping machine and the PLC input point and the ground wire.
2. It is strictly forbidden to move or remove the upper and lower fixed limit blocks.
3. The turntable of the stretch film packaging machine should run clockwise.
4. It is strictly forbidden to stand people or pile up any objects under the membrane system.
5. When the film system roller is rotating, it is strictly forbidden to reach inward or reach into other objects to prevent damage to the rubber roller or fingers.
6. It is strictly forbidden to put your hand into the vicinity of the chain for maintenance or inspection, or perform other operations during operation to prevent hand injury.
7. When the stretch film packaging machine is running, the operator should stand in a safe place at a certain distance from the turntable. When the machine stops after a working process, it should be close to the machine to prevent the goods from being scattered and hurt people. If necessary, a safety isolation net should be installed (self-provided) or otherwise customized).

Common faults and solutions in the operation of stretch film packaging machines

Fault 1: The turntable of the wrapping machine does not turn
Solution: First check whether the inverter is damaged, and if it is not displayed, it needs to be replaced; if the parameter setting is wrong, it needs to be reset; it is also necessary to check whether the chain is broken, and if it is broken, it needs to be replaced.

Fault 2: The machine cannot run normally when it is just started
Solution: First check whether the power supply is connected normally, then turn on the power again, then check whether the internal power supply is connected, turn on the power switch and then close the switch in the power distribution cabinet.

Fault 3: The inverter of the equipment has an overload alarm
Solution: First of all, ensure the stability of the voltage, otherwise it is necessary to improve the quality of the power supply or the acceleration time of the frequency conversion.

Fault 4: The turntable of the stretch film packaging machine cannot stop
Solution: First check whether the DIP switch is damaged, and then check whether the place close to the switch is damaged. If it is damaged, it needs to be replaced in time.

Fault 5: There is noise after the mechanical turntable rotates
Solution: If the ground is uneven, the user is required to tidy up or change the place of placement; if some supporting rollers are seriously worn, replace the supporting rollers.

Fault 6: The mechanical active rubber roller and the membrane frame connector (square rod) are damaged
Solution: If it is damaged during transportation, replace it with a new one; if it is damaged by human beings, replace it with a new one.

Fault 7: The film feeding speed of the mechanical film frame cannot be adjusted
Solution: If the mechanical DC speed control box is damaged and there is no output, replace it with a new mechanical speed control box; if the mechanical speed control box is damaged (the possibility is very small), replace it with a new mechanical speed control box.

Fault 8: The machine often breaks the film
Solution: The quality of the stretch film used by the machinery is poor. It is recommended to buy the film from the factory machinery manufacturer, or the stretch film professionally provided by the Wulian Yuncang Material Mall. The quality is guaranteed and the price is reasonable; the sharp corners of the packaged goods are too sharp, Try to avoid or trim sharp corners, it is recommended to use paper corner protectors to slow down the film feeding speed; if there are burrs on the guide roller, use sandpaper to polish and repair; if the mechanical turntable speed is too fast or the film feeding speed is too slow, adjust the speed to make the stretched film The draw ratio decreases.

Fault 9: The mechanical film holder does not feed the film
Solution: If the DC power supply is not connected properly, reconnect the mechanical DC power supply; if the DC motor is burnt out, replace the mechanical DC motor; if the DC speed control box is damaged, replace the mechanical DC speed control box; if the DC speed control box is damaged , then replace the mechanical DC speed control box again for insurance damage.

Trouble 10: The mechanical film holder does not rise or fall
Solution: If the lifting motor is damaged, the multimeter or shaker will detect that the motor is missing or broken down. If it cannot be repaired on site, replace it with a new mechanical motor; if the upper and lower limit switches are not pressed together, adjust the position of the mechanical limit switch so that It can be pressed together, adjust the distance between the mechanical membrane frame and the column, and replace the larger limit block; if the limit switch wiring is loose, then re-press the mechanical limit switch; if the limit switch is damaged, replace it with a new mechanical limit switch; if the PLC has no output, replace it with a new mechanical PLC.

Maintenance method of stretch film packaging machine
1. Lubrication: The lubricating positions of each part of the stretch film packaging machine are refueled and changed on time, and the oil quality meets the requirements.
2. Safety: Strictly implement the fixed machine, fixed person, fixed job responsibilities and shift shift system, control the stretch film packaging machine system to maintain normal operation, good grounding, ensure safe and normal transmission, and no hidden dangers of accidents.
3. Cleaning: The inside and outside of the stretch film packaging machine are clean, without dust, black stains and rust; all parts are kept in good condition, such as no oil, no bruises, scratches, and scratches; there are no water, air, or oil leaks in other parts And so on, clean and hygienic.
