With the rapid development of printing technology, paper cutting machines, as essential processing equipment for printing enterprises, have received more and more attention. Its technology is developing rapidly, with new products emerging in large numbers, achieving excellent results in cutting accuracy, automation level, and operational performance. This article mainly shares with you the maintenance methods for the blades of a paper cutting machine during its actual use:
Paper cutting machine
1. The pull rod of the paper cutter cutterbed is divided into two parts: upper and lower. The upper part mainly connects the left threaded pull rod with nut 3, the middle part is the adjusting nut, and the lower part is the right threaded pull rod with nut 2, which is connected to the lower pull rod seat through the safety bolt. When installing a new or newly ground knife, it is necessary to use a handle and long bolts to rotate the machine to gradually lower the knife bed. When the blade drops to a low position and has not yet cut to the blade pad, rotate the adjusting nut 1 to adjust the spacing between the cutting blade and the blade pad, that is, the required position for the cutting blade to move up and down. Tighten screw caps 2 and 3 together.
2. In order to make the blade sharper and brighter, a precise grinding of the blade should be carried out with an oilstone before cutting, and some soap and paraffin should be applied to the blade to extend its service life and make the cut edges smoother.
3. The balance between the left and right, top and bottom of the cutting knife is mainly achieved by adjusting the screws in the sliding groove of the knife door. If the adjusting screws are turned clockwise, the paper cutting knife will be adjusted higher, and vice versa. Due to the different heights of the blades (new blades are higher, old blades that have been ground are lower), operators must adjust the height of the cutting tool frame (tool holder) in a timely manner when exchanging blades to prevent damage to mechanical components or the formation of safety installation fractures.
4. Pay attention to the wear condition of the left and right stoppers inside the knife door when the cutting knife is used for a long time. When the adjustment of the left and right screws cannot meet the requirements, it is necessary to adjust the left and right stoppers to meet the requirements.
5. After changing the tool, it is necessary to stop a detailed inspection. If any abnormal phenomena are found, exchange them in a timely manner. If there are no errors, empty cut several times before stopping cutting.
