[0010] The utility model further sets up: the branch board is provided with vertical slide groove, the slide groove runs through the top of branch board and communicates in slide groove, the control assembly includes the slide bar of slide connection in the slide groove, the slide block is away from the side wall top of cutting roller and sets up obliquely, the bottom end of slide bar is the inclined plane that is parallel with the side wall inclined plane of slide block and abuts, the top end of slide bar still is provided with counterweight spare.

[0011] The utility model further sets up: two the top support of slide bar is fixedly connected with fixed link, the counterweight spare is specifically a plurality of counterweight blocks that set up on fixed link.

[0012] The utility model further sets up: the lower surface of counterweight block is provided with the recess groove that is inserted for fixed link.

[0013] The utility model has the following beneficial effects: when carrying out paper edge cutting work, paper passes between cutting roller and abutment roller, under the action of control assembly, make cutting roller and abutment roller clamp tightly, and make cutting roller rotate through motor drive, make paper in the process of transmission, through the cutting block of cutting groove both sides to the edge of paper cutting, thereby cutting the edge of paper and cutting out irregular shape.

[0018] The utility model makes further detailed explanation in combination with the drawings.

[0019] Identical parts are indicated by identical reference numerals. It should be noted that the words "front", "back", "left", "right", "up" and "down" used in the following description refer to the directions in the drawings, and the words "bottom surface" and "top surface", "inner" and "outer" refer to the directions towards or away from the geometric center of a particular component.

[0020] As shown in the figure, a paper irregular edge cutting device, comprising two support plates 1, a cutting roller 2 and an abutting roller 3 are rotatably connected between the two support plates 1, a cutting groove 4 is formed on the surface of the cutting roller 2 along the circumferential surface thereof, a plurality of cutting blocks 5 are uniformly arranged on the inner walls of the cutting groove 4 along the circumferential direction, a motor 6 is installed on the outer wall of the support plate 1 for driving the cutting roller 2, and a control assembly for controlling the abutting roller 3 to abut against the cutting roller 2 is further included.

[0021] When cutting the edges of the paper, the paper passes between the cutting roller 2 and the abutting roller 3, and under the action of the control assembly, the cutting roller 2 and the abutting roller 3 clamp the paper, and the cutting roller 2 is driven to rotate by the motor 6, so that the edges of the paper are cut by the cutting blocks 5 on both sides of the cutting groove 4 during transmission, thereby cutting irregular shapes on the edges of the paper.

[0022] Two rubber sleeves 7 are sleeved and fixedly connected on the abutting roller 3, and the two rubber sleeves 7 correspond to the cutting blocks 5 on the inner walls of the cutting groove 4 respectively, when the abutting roller 3 abuts against the cutting roller 2, the edges of the cutting blocks 5 on the abutting roller 3 are clamped during the clamping of the paper, and the surface of the rubber sleeve 7 is deformed by extrusion, so that the edges of the paper can be smoothly cut under the action of the cutting blocks 5.

[0023] The inner walls of the two support plates 1 are provided with sliding grooves 8 in the horizontal direction, the sliding grooves 8 are slidably connected with sliding blocks 9, the abutting roller 3 is rotatably connected between the two sliding blocks 9, and the control assembly is used to push the sliding blocks 9 to slide towards the cutting roller 2. The support plate 1 is provided with a vertical sliding groove which penetrates the top of the support plate 1 and communicates with the sliding groove 8, the control assembly includes a sliding rod 10 which is slidably connected in the sliding groove, the top of the side wall of the sliding block 9 away from the cutting roller 2 is provided in an inclined manner, the bottom end of the sliding rod 10 is provided in an inclined manner which is parallel to the inclined surface of the side wall of the sliding block 9 and abuts against it, and the top end of the sliding rod 10 is further provided with a counterweight.

[0024] Under the action of the counterweight, the sliding rod 10 has a downward movement tendency and pushes the sliding block 9 to slide towards the cutting roller 2, thereby simultaneously pushing the abutting roller 3 to abut against the surface of the cutting roller 2, so as to ensure the smooth progress of the cutting work.
