Sheet-fed paper cutter is a kind of cutting machine, which is widely used and can be used for cutting paper, leather, plastic, cardboard and other materials. The paper cutter is mainly composed of a main engine (also known as a gantry), a worktable, a paper pushing mechanism, a paper pressing mechanism, and a cutting mechanism. The paper-pushing mechanism is used to push the paper for positioning and make the back order, and the paper-pressing mechanism compresses the positioned paper to ensure that the original positioning accuracy is not damaged during the cutting process. The cutting mechanism is used to cut the paper, and the side baffle is Side stop gauge, the workbench plays a supporting role.
The production of printing, packaging, bookbinding and other production from cutting to printing finished products and the cutting of raw books after binding all require paper cutters for cutting, so paper cutters are important equipment for post-press processing. Sheet-fed paper cutters are widely used in printing plants, bookbinding plants, packaging plants, paper products processing plants, etc.
Sheetfed Cutter Cutting Process
1) Determine the position of the pusher according to the size of the paper to be cut
2) Make the paper that has been flushed close to the front surface of the pusher and the side baffle to position the paper
3) The paper press first descends to compress the paper, and then the cutter descends to cut the paper
4) After cutting, the cutter first leaves the paper stack and returns, and then the paper press rises and resets.
Factors affecting the safe use of paper cutters
The safety of the paper cutter is an issue that is easily overlooked by many digital printing practitioners. The following aspects affect the safe use of the paper cutter:
1. brakes. In order to save money, many manufacturers adopt the principle of circuit braking, that is, the upper and lower limit sensors cut off the power supply of the cutter motor to brake. This kind of device may cause "slippery knife" in the case of sudden power failure, loose socket, sensor failure, etc. extremely dangerous situation. 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 two buttons to be pressed at the same time, otherwise the cutter motor will not act, which can ensure the absolute safety of single-person operation.
3. In the actual use process, 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 operate to ensure safety.
4. The above are the safety factors that affect the use process. Then, when replacing the blade during maintenance and maintenance, use the blade holder 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 put aside at will to avoid hurting people.
