The cutting system of bag-making machine is composed of cutter, length regulator, overrunning clutch, welding line adjustment and so on.
1. Cutting tool: it is the most important part of the system. It adopts moving tool and sliding guide, and the floating mechanism is pressed by spring, and the upper and lower knives can be adjusted.
There are adjusting screws, 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: the bag-making length is adjusted by changing the position of the connecting rod sleeve on the eccentric drag plate to control the bag-making length through the elastic handwheel
With nuts to adjust the bag size.
3, overrunning clutch: plastic overrunning clutch is an important part of the machine, its quality, performance directly affects the length of the product error, but in use
In the process, due to the high frequency of work, so its life has a certain limit. If it is found that there is an error in the bag-making length in the production process (general connection)
After continuous production for half a year), if other faults cannot be solved, the clutch can be disassembled for inspection and maintenance.
4. Adjust the distance between welding line and cutting line: the distance between welding line and cutting line is generally 5-10mm. Rotate the hand wheel on the adjustment frame to make the beam roller
Rise or fall a certain distance to 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 machine
The outer end of the cutter. If the welding line is not parallel to the bottom line, loosen the fastening screw of one bevel gear and rotate the hand wheel to make one end of the beam roller
To rise or fall; ascend. After the production is stable, the gear screws are locked.
5. Adjustment method of welding tool: put a piece of thin paper on the support seat, rotate the big hand wheel in the body box by hand to make the welding tool at the lower dead point, and loosen the nut
Adjust the nut and pull the compression degree of both ends of the thin paper by hand until approximately equal. After adjusting, 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 cots, light-controlled film screen, curtain and light
Electric tracking machine and electronic control line composition, its function is to maintain the normal film delivery process. When the machine is running, the film feeding speed is too fast to cover the light
When controlling the ray, the device will give instructions to stop the motor from rotating the feeding.
