The bag making machine equipment is now mainly used in major industries of people's livelihood such as medicine and food, so as to meet the supply and demand of materials. Now the domestic bag making machine market occupies a large area of packaging. What is the cutting system of the bag making machine and what is it composed of?
The cutting system of bag making machine is composed of cutter, length adjuster, overrunning clutch and welding line adjustment.
1. Cutter: it is the most important part of the system. It is a floating mechanism with movable cutter and sliding guide and compressed by spring. The upper and lower knives can be adjusted. An adjusting screw is arranged therein, 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 adjuster: the bag making length is adjusted by changing the position of the connecting rod on the eccentric carriage to control the bag making length, and the bag making size is adjusted by loosening the hand wheel and nut.
3. Overrunning clutch: sinoplastics overrunning clutch is an important part of this machine. Its quality and performance directly affect the error of product length. However, in the process of use, due to the high working frequency, its service life is also limited. If it is found that there is an error in the length of bag making during the production process (generally after continuous production for half a year), and other faults cannot be eliminated, the clutch can be disassembled for 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 generally 5-10mm. Turn the hand wheel on the adjusting frame to raise or lower the beam roller for a certain distance to obtain an ideal cutting line. In order to observe the quality of the welding wire, the welding wire position of the single bobbin thread 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 hand wheel to raise or lower one end of the beam roller; After the production is stable, lock the screws of the gear.
5. Adjustment method of welding knife: put a piece of thin paper on the support base, turn the big hand wheel in the machine body box by hand to make the welding knife at the bottom dead center, loosen the nut and adjusting nut, and try to pull the compression degree of both ends of the thin paper by hand until it is about equal. After adjustment, lock the nut to prevent loosening.
6. Automatic light controlled feeding device: this device is composed of servo motor, feeding rubber roller, light controlled film shutter, shade, photoelectric tracking machine and electric control line. Its function is to keep normal film feeding during production. When the machine is running, when the film feeding speed is too fast to cover the light control ray, the device will send a command to stop the motor from rotating and feeding.
