[0007] Through the above technical solution, the cutting knife slides downward quickly and is used in conjunction with the cutting groove, so that the cardboard can be cut quickly, the cut is smooth, and the product quality is improved.

[0008] As a further improvement of the above scheme, the top of the support plate is fixedly connected to a top plate, the top of the top plate is rotatably installed with a rotating shaft, one end of the rotating shaft is transmission-connected to the output end of the motor through a second transmission assembly, and an eccentric disk corresponding to the bracket is fixedly installed in the middle of the rotating shaft.

[0009] Through the above technical solution, the eccentric disk squeezes the bracket to drive the cutting knife to cut, so that the cardboard works intermittently, so that the length of the cardboard is consistent each time it is cut, thereby improving the work efficiency.

[0010] As a further improvement of the above solution, a material discharge position corresponding to the cutting mechanism is provided at one end of the base close to the cushion block.

[0011] As a further improvement of the above solution, the second transmission assembly and the first transmission assembly both include a pulley and a transmission belt, and a through groove corresponding to the eccentric disc is opened in the middle of the top plate.

[0012] As a further improvement of the above solution, the surface of the conveyor belt is provided with anti-slip grooves, and the cardboard continues to move forward through the conveyor belt after cutting, and the cut cardboard is pushed to the unloading place for collection.

[0013] Through the above technical solution, the unloading place can be set as an inclined block, so that the cut cardboard slides down the slope and falls into the collection box in an orderly manner, without the need for operators to manually pick up and place, thereby speeding up work efficiency.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] The utility model drives the eccentric disk to rotate while the rotating shaft rotates, so that the eccentric disk squeezes the bracket to slide inside the slide groove, thereby driving the cutting knife to fall quickly through the mounting plate, and the cardboard is quickly cut through the cooperation of the cutting groove. The conveyor belt continues to convey and continues to push the cut cardboard forward, and the cut cardboard is pushed to the unloading place for collection. When the eccentric disk is separated from the bracket, the spring resets the bracket, and the reciprocating work is used to cut the cardboard to a fixed length. The design can automatically cut the cardboard to a fixed length, and the incision is smooth, which speeds up the work efficiency and improves the product quality. BRIEF DESCRIPTION OF THE DRAWINGS
