The flat sheet paper cutter is a kind of cutting machine with a wide range of uses. It can be used to cut paper, leather, plastic, cardboard and other materials. The paper cutter is mainly composed of the main machine (also known as the gantry), workbench, paper pushing mechanism, paper pressing mechanism, cutting mechanism, etc. The paper pushing mechanism is used to push the paper to position and make a post-rule, and the paper pressing mechanism presses the positioned paper to ensure that the original positioning accuracy is not destroyed during the cutting process. The cutting mechanism is used to cut the paper, the side baffle is used as a side baffle, and the workbench plays a supporting role.
Printing, packaging, book binding and other production from cutting to printing finished products and cutting of rough copies after binding require paper cutters for cutting, so paper cutters are important equipment for post-printing processing. Flat sheet paper cutters are widely used in printing plants, binding plants, packaging plants, paper product processing plants, etc.
Cutting process of flat sheet paper cutter
1) Determine the position of the paper pusher according to the size of the paper to be cut
2) Position the paper close to the front surface and side baffle of the paper pusher
3) The paper presser first descends to press the paper, and then the cutter falls to cut the paper
4) After cutting, the cutter leaves the paper stack and returns, and then the paper presser rises and resets.
Factors affecting the safe use of paper cutters
The safety of paper cutters is an issue that many digital printing practitioners tend to ignore. The following aspects affect the safe use of paper cutters:
1. Braking device. In order to save money, many manufacturers use the circuit braking principle, that is, the upper and lower limit sensors cut off the power supply of the cutter motor to brake. This device may cause extremely dangerous conditions such as "slipping" in the event of sudden power outages, loose sockets, sensor failure, etc. In order to prevent this from happening, it is necessary to use a motor assembly with a mechanical brake device, so that no matter what circuit failure occurs, the motor is locked to avoid accidents.
2. Double button operation principle. This requires that both buttons be pressed at the same time, otherwise the cutter motor will not work, which can ensure the absolute safety of single-person operation.
3. In actual use, two people often cooperate to operate, so the situation becomes very dangerous, which requires the paper cutter to be equipped with front and rear safety covers. When the safety cover is opened, the motor will not work to ensure safety.
4. The above are safety factors that affect the use process. Therefore, during maintenance and care, pay attention to using the blade holder when replacing the blade to ensure that the blade edge is closed, which not only ensures the safety of people, but also ensures that the blade edge is not damaged.
5. Furthermore, the removed blade must not be left at will to avoid hurting people.
