Composition of cutting system of bag-making machine

1, knife: Using moving knife and sliding guide, by the spring pressure of the floating mechanism, the upper and lower knives can be adjusted. The utility model is provided with an adjusting screw, which can be used to adjust the tightness of the cutter, and can well eliminate the phenomenon that raw materials are difficult to cut. 2, bag length regulator: bag length regulation to change the position of the connecting rod on the eccentric drag board to control the bag length, through the tightening hand wheel and nut to adjust the bag size. 3, overrunning clutch: The plastic overrunning clutch is an important part of the machine, its quality and performance directly affect the error of product length, but in the use process, due to high frequency, so its life also has a certain limit. If the bag-making length error is found in the production process, and other troubleshooting still can not be solved, the detachable clutch inspection and maintenance. 4. Adjustment of the distance between the welding line and the cutting line: the distance between the welding line and the cutting line is 5. In order to observe the quality of the welding line, the welding line with single bottom line can be adjusted to the outside end of the machine cutter. If the welding line is not parallel to the bottom line, the fastening screw of an umbrella gear can be loosened, and the hand wheel can be turned to make one end of the beam roller rise or fall. 5. Welding knife adjustment method: Put a piece of thin paper on the support seat, turn the big handwheel in the body box by hand to make the welding knife at the lower dead point, loosen the nut, adjust the nut, and test the tightness of the two ends of the thin paper by hand, until it's about even. After adjustment, lock the nut in case it comes loose. 6. Automatic light-controlled feeding device: This device is composed of servo motor, feeding rubber roller, light-controlled shutter, curtain, photoelectric tracker and electric control wire, its function is to keep normal feeding film in the production process. Machine operation, when the film feed speed is too fast to cover the light control ray, the device will issue instructions to stop the motor feed.
