The cutting system of bag making machine is composed of cutting knife, length regulator, overrunning clutch, welding line adjustment and so on.

1, cutting knife: is the most important part of the system, is the use of moving knife and sliding guide, by the spring pressure floating mechanism, up and down the knife can be adjusted. Which is provided with adjusting screws, can be used to adjust the cutting tool tightness, can be very good to eliminate the phenomenon of raw material difficult to cut.

2. Bag-making length regulator: the bag-making length is adjusted by changing the position of the connecting rod set on the eccentric drag plate to control the bag-making length, and the bag-making size is adjusted by tightening hand wheel and nut.

3, beyond the clutch: plastic beyond the clutch is an important part of the machine, its quality, performance directly affects the length of the product error, but in the process of use, because of the high frequency of work, so its life also has a certain limit. If it is found that there is an error in the bag-making length during the production process (generally after half a year of continuous production), and other faults can not be solved, the clutch can be disassembled for inspection and maintenance.

4, welding line and cutting line distance adjustment: welding line and cutting line distance is generally 5-10mm, turn the adjusting frame of the handwheel, the beam roller rise or fall a certain distance, get the ideal cutting line. In order to observe the quality of the welding line, the welding line position of the single bottom line can be adjusted to the outer end of the machine cutter. If the welding line and the bottom line are not parallel, you can loosen the fastening screw of a bevel gear, turn the handwheel to raise or lower one end of the beam roller; After stable production, the screw of the gear is locked.

5. Welding knife adjustment method: pad a piece of tissue paper on the supporting seat, rotate the big hand wheel in the body box to make the welding knife at the bottom dead point, loosen the nut, adjust the nut, and try to pull the compression degree at both ends of the tissue paper by hand until it is about equal. After adjustment, lock the nut to prevent loosening.

6. Automatic light-controlled feeding device: The automatic light-controlled feeding device of plastic bag making machine is composed of servo motor, feeding roller, light-controlled film mask, curtain, 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 to cover the light control ray, the device will issue an instruction to make the motor stop rotating feeding.
