2. Insufficiency of winding tension - Treatment method: When the voltage of the lower tension control device of the magnetic powder clutch is controlled high, the winding tension is still not enough, the winding film material is loose, and the winding shaft can be grasped by hand to make it Stop turning. Note that the output torque of the magnetic powder clutch is not enough, and the magnetic powder therein is reduced or invalid due to a large amount of time. In this case, the magnetic powder clutch should be disassembled, and a new amount of magnetic powder of a certain amount of traffic can be added to the normal work.
The main and common faults are basically two types of faults, and some minor faults in actual operation. Experienced operators can generally handle the faults themselves.
Second, the bag machine common faults and treatment methods 1, start stepping motor has a different sound, can not send the film - handling methods: (1) Check the main motor steering is correct, adjust the arrow to the correct direction. (2) Whether the stepper motor driver shows a fault or not, shutting off the main power supply and resuming power can return to normal.
2, the length of the film feeding process is different, the feed size is shorter than the pre-adjusted size of 5mm or more, the work process intermittently does not send film - processing methods: (1) Photoelectric sensitivity adjustment is not good or the polarity is wrong. (2) Earth leakage or short circuit between the photoelectric switch socket and the earth should be replaced. (3) The feeding speed is lower than the feeding speed. It is necessary to loosen the lamination bars, check the discharge part performance, and troubleshoot.
3. The torque of the smashing motor is obviously reduced and the bag size is not accurate. It means that the stepper drive is faulty, or the connecting part of the rubber roller and the stepping motor is stuck.
4. Photoelectric tracking is inaccurate during bag making. Processing methods: (1) Optoelectronic eye adjustment method and working status are not selected correctly. Correct adjustment is required according to the specification. (2) The pre-adjusted film feeding length (when adjusting the blank bag) and the actual bag size error are too large. The line length or pressure adjustment and adjustment device should be set again. (3) The excessive film resistance or poor quality of the previous process product should be checked and replaced.
5, discharge speed is low or not working - handling methods: (1) eye position switch bad contact or cam angle is not good, should be adjusted or replaced. (2) Breakdown of thyristor or rectifier tube of discharge speed regulating circuit board shall be repaired or replaced.
Mechanical equipment and its processing objects, here we specifically refer to plastic film, have a mutually adaptable characteristics, that is, a mechanical equipment can only process plastic film within a certain range of properties, we understand the nature of plastic film based on , starting from the three elements of the bag, that is: pressure, temperature, hot pressing time, in the bag (on the premise of guaranteeing the hot pressing strength, relatively speaking) the hot pressure is greater, the hot pressing temperature is lower, the hot pressing time To be long, the compound bag hot pressure seal after such treatment is beautiful, beautiful, and upright.
One automatic spraying line, one semi-automatic spraying line, and three bakeries, which can complete all kinds of spraying and coating of products with sizes below 6 meters
Composite film slitting machine, bag making machine common faults and treatment methods
First, the common faults and processing methods slitting machine 1, slitting photoelectric tracking is not accurate - processing methods: (1) photoelectric eye adjustment method and the working state selection is not correct, should be adjusted according to the instructions; (2) traced The color difference between the line or edge and the surrounding film material is not obvious, and the contrast of the color difference should be increased.
