Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 to 4, the present invention provides a technical solution: a precision slitting device for polypropylene honeycomb plates comprises a frame 1, wherein a supporting roller set 2 is arranged on the inner side of the frame 1 close to the bottom of the frame, the supporting roller set 2 supports the plates and is convenient for better pushing the plates to move in the feeding process, a fixed plate 3 is fixedly connected to the bottom of the middle of the frame 1 close to the top of the frame, gears 4 are rotatably connected to the front ends of the two sides of the fixed plate 3, a driving machine 5 is arranged at the rear end of the fixed plate 3, the driving machine 5 is preferably a speed regulating motor, an output shaft of the driving machine 5 is arranged on the axis of one gear 4, a connecting rod 6 is hinged to the front end of the gear 4 close to the edge of the gear, a cutter device 7 is hinged to the bottom end of the connecting rod 6, one gear 4 of the two gears 4 is driven to rotate by the driving machine 5, the two gears 4 rotate in opposite directions due to meshing, and then, and then the cutting of the plate is completed.

Specifically, the cutter device 7 includes a fixing frame 71 and a cutter body 72, the top of the fixing frame 71 close to the side thereof is hinged to one end of the connecting rod 6 far away from the gear 4, a buffer device 73 is installed between the fixing frame 71 and the cutter body 72, the cutter body 72 is driven by the connecting rod 6 to move downwards when the driving machine 5 operates, and the cutter body 72 acts on the surface of the plate to cut the plate.
