Bubble bag making machine is a machine for making various plastic packaging bags or other material packaging bags. Its processing range is various sizes, thicknesses and specifications of plastic or other materials packaging bags. Generally speaking, plastic packaging bags are the main products. Let's take a brief look at its cutting system.
1. Cutter: It is an important part of the system. It is a floating mechanism with a moving knife and a sliding guide rail, which is compressed by a spring, and the upper and lower knives are adjustable. There is an adjustment screw, which can be used to adjust the tightness of the knife, which can well eliminate the phenomenon that the raw material is difficult to cut.
2. Bag length regulator: The bag length is adjusted by changing the position of the connecting rod sleeve on the eccentric drag plate, the bag length is controlled, and the bag size is adjusted by tightening the handwheel and nut.
3. Overrunning clutch: The aluminum-plastic overrunning clutch is an important part of this machine, and its quality and performance directly affect the error of the product length. However, during use, due to its high operating frequency, its service life is limited. If the bag length error is found during the production process and other faults cannot be solved, the clutch can be disassembled for inspection and repair.
4. Adjustment of the distance between the welding line and the cutting line: The distance between the welding line and the cutting line is generally 5-10 mm. Turn the hand wheel on the adjustment frame to raise or lower the beam roller by a certain distance to obtain the ideal cutting line. In order to observe the quality of the welding line, the welding line position of a single bottom line can be adjusted to the outer end of the machine tool. If the welding line is not parallel to the bottom line, loosen the fastening screw of a bevel gear and turn the hand wheel to raise or lower one end of the beam roller. Tighten the screw of the gear after the production is stable.
5. Welding knife adjustment method: Put a piece of thin paper on the support seat, turn the large hand wheel in the machine box by hand to make the welding knife at the bottom dead center, loosen the nut, adjust the nut, and try to pull the compression degree of both ends of the thin paper by hand until it is approximately equal. After adjustment, lock the nut to prevent loosening.
The above is a brief introduction to the cutting system of the bubble bag making machine. I hope you can learn more about it.
