[0002] During regeneration granulation, the flexible material needs to be broken before granulation, which is usually done with a traditional crusher. Crusher is widely used in daily production. For example, the patent document with application number 201610278429.6 discloses an agricultural harvester, including: a frame; a threshing and separation system carried by the frame; a cleaning system carried by the frame; a mounting surface carried by the frame; and a residue system including a shredder carried by the frame, and the residue system is supplied with crop materials from the threshing and separation system and / or the cleaning system.

[0003] In the production process of recycled granulation, the traditional crusher is a rolling shredder without a feeding device, and the manual feeding is extremely uneven. Due to the fast rolling speed and the irregular shape of the flexible material, which is tightly entangled with each other, it is easy to entangle the workers' clothes and fingers during feeding, posing a great potential for accidents. In addition, the noise exceeds the standard during shredding, which is not conducive to use. Therefore, we proposed a cross-cutting shredder to solve the above problems. Summary of the invention

[0004] Based on the technical problems existing in the background technology, the present invention proposes a cross-cutting shredder.

[0005] The present invention provides a cross-cutting shredder, comprising a frame and a belt conveyor rotatably mounted in the frame, a cross plate and a vertical plate are welded to one side of the frame, a pressure roller and a cross-cutting roller are rotatably mounted to one side of the vertical plate, a plurality of cross-cutting blades are fixedly mounted to the outer side of the cross-cutting roller, a mounting plate is welded to the side of the cross plate away from the frame, a first bevel gear is rotatably mounted to one side of the mounting plate, a first sprocket is fixedly mounted to one end of the cross-cutting roller, a second sprocket is fixedly mounted to one end of the first bevel gear, and the same chain is installed on the first sprocket and the second sprocket for transmission;

[0010] Preferably, the vertical cross-section of the first brake piece is a rectangular structure, and a wear-resistant pad is welded to one end of the sliding rod located in the sleeve.

[0011] Preferably, a plurality of obliquely arranged spring plates are welded on the inner wall of the sleeve, the spring plates are located on a side of the first brake plate close to the frame, and the spring plates cooperate with the first brake plate.

[0012] Preferably, the number of the cross-cutting blades is three to six, and the three to six cross-cutting blades are arranged in a ring shape with equal intervals.

[0013] Preferably, a baffle is welded to one end of the spline shaft away from the circular shaft, and the outer side of the second gate plate does not contact the inner wall of the sleeve.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] (1) The frame, belt conveyor, vertical plate, horizontal plate, pressure roller, cross-cutting roller, discharge plate, mounting plate and cross-cutting blade are coordinated, and the pressure roller is driven by a stepper motor to rotate counterclockwise, and the rotation direction of the belt conveyor is set to be clockwise, and the conveying speed of the belt conveyor is consistent with the angular velocity of the pressure roller.

At this time, the first brake pad will not rotate with the circular shaft. When the second motor drives the eccentric wheel to rotate, the long axis surface of the eccentric wheel pushes the slide rod to move toward the inner side of the sleeve. When the slide rod pushes the first brake pad to fit tightly with the second brake pad, the first brake pad and the second brake pad rotate synchronously. At this time, the first brake pad drives the second bevel gear to rotate through the sleeve. The first sprocket is driven to rotate through the transmission action of the first bevel gear, the second sprocket and the chain, and the first sprocket drives multiple cross-cutting blades to rotate through the cross-cutting roller.
