Bag making Machine (English name :Paper Bag Machine) is the production of a variety of plastic bags or other material bags of machinery, its processing range for a variety of sizes of different thickness specifications of plastic or other materials of packaging bags, generally speaking to plastic bags as the main products.
Cutting system of bag making machine:
The cutting system consists of cutter, length regulator, overrunning clutch, welding line adjustment and so on.
1, cutting knife: is an important part of the system, is the use of moving knife and sliding guide, by the spring pressure floating mechanism, the upper and lower knife can be adjusted. The adjusting screw is arranged, which can be used to adjust the tightness of the cutter, and can well eliminate the phenomenon of difficult cutting of raw materials.
2, bag-making length regulator: bag-making length is adjusted by changing the position of connecting rod sleeve on the eccentric dragging plate to control the bag-making length, and bag-making size is adjusted by tightening the hand wheel and nut.
3, overrunning clutch: the plastic overrunning clutch is an important part of the machine, its quality, performance directly affect the product length error, but in the process of use, because of the high working frequency, so its life also has a certain limit. If it is found that the bag-making length error occurs in the production process (usually after half a year of continuous production), but it cannot be solved after troubleshooting other faults, the clutch can be disengaged for inspection and maintenance.
4. Adjustment of welding line and cutting line distance: the distance between welding line and cutting line is generally 5-10mm. Rotate the handwheel on the adjusting frame to make the beam roller rise or fall a certain distance to get the appropriate cutting line. In order to observe the quality of the welding wire, the position of the single bottom line welding wire can be adjusted to the outer end of the machine cutter. If the welding line and the bottom line are not parallel, loosen the fastening screw of one bevel gear and turn the handwheel to raise or lower one end of the roller of the beam; After the production is stable, tighten the screw of the gear.
5. Welding knife adjustment method: put a sheet of thin paper on the supporting seat, rotate the large hand wheel in the body box by hand to make the welding knife at the lower dead point, loosen the nut and adjust the nut, and try to pull the compression degree of both ends of the thin paper by hand until it is about equal. After adjusting, lock the nut tightly to prevent loosening.
6, automatic light control feeding device: the device is composed of servo motor, feeding roller, light control film screen, screen, photoelectric tracking machine and electric control line, its function is to maintain normal film feeding in the production process. When the machine is running, when the film feeding speed is too fast and the light control rays are covered, the device will issue instructions to stop the motor rotating and feeding.
