Detailed ways

The utility model will be further described below in conjunction with the accompanying drawings 1 to 4 and the embodiments.

An edge-trimming device for special paper, including a cutting table 1, a cutting mechanism, and a positioning mechanism. The cutting table 1 is provided with a knife slot. The cutting mechanism includes a bracket 2, a driving body 3, and a knife body 4. The driving body The body 3 is a hydraulic cylinder, the bracket 2 is provided with a chute, and a movable plate 5 is slidably fitted in the chute. The movable plate 5 is connected to the driving body 3. The cutter body 4 is located directly above the knife slot and is installed at the lower end of the movable plate 5. The plate 5 is provided with pressure rods 6 and elastic pressure blocks 7 on both sides of the cutter body 4. The positioning mechanism is installed on the cutting table 1 and includes a main lifting mechanism and a residual lifting mechanism located on both sides of the cutting mechanism. , the main lifting mechanism includes a main vertical plate 8 located on the same side of the elastic pressure block 7 , and the remaining lifting mechanism includes a telescopic vertical plate 9 and a return spring 10 located on the same side of the pressure rod 6 , the telescopic vertical plate 9 can be pressed by the pressure rod 6 Press and retract downward, and the return spring 10 is used to extend and reset the telescopic vertical plate 9 .

The elastic pressing block 7 is installed on the movable plate 5 through the provided shaft 11 and the pressing spring 12 to realize the elastic function, so that the cutter body 4 is fed, and the elastic pressing block 7 continues to maintain the state of pressing the special paper to ensure stability.
