Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] In order to solve the problem that the existing spiral equipment continuously transports the material into the shredder at a certain rate, some materials with smooth surfaces and light cloth structures will have a small amount of staying above the knife roller; please refer to Figure 1-4 , the utility model provides the following solutions:

[0021] A double-shaft shredder extrusion feeding mechanism includes a knife roller frame 1 and a double-shaft knife roller 3. The double-shaft knife roller 3 is installed inside the knife roller frame 1. The double-shaft knife roller 3 is rotatably connected to the knife roller frame 1. Side clamping claws 4 are arranged on both sides of the double-shaft knife roller 3. The double-shaft knife roller 3 includes a toothed knife disc 301. Opposite cutting grooves 302 are arranged between the toothed knife discs 301. The side clamping claws 4 are located inside the opposite cutting grooves 302. Lubricating shaft grooves 101 are arranged on both sides of the knife roller frame 1. 101 extends to the outer surface of the knife roller frame 1, and both ends of the knife roller frame 1 are provided with an electric control sleeve 2, and the electric control sleeve 2 is provided with a track inner groove 202, and the track inner groove 202 is provided with a pulley 203, and the pulley 203 is slidably connected with the track inner groove 202, and a tensioning pull belt 201 is provided below the pulley 203, and the tensioning pull belt 201 at one end is connected to the closing swing shaft 5 through the upper connecting shaft 501, and the tensioning pull belt 201 at the other end is connected to the reset swing shaft 6 through the lower connecting shaft 601;

[0022] In this embodiment, the side clamping claws 4 are distributed on both sides of the double-axis knife roller 3. The material is put into the knife roller frame 1 from above. The pulley 203 inside the electric control sleeve 2 at one end of the knife roller frame 1 moves downward, and the closing swing shaft 5 is driven to rotate clockwise through the tensioning pull belt 201. When the closing swing shaft 5 rotates inward, it will drive the side clamping claws 4 on both sides to flip in the same direction. The side clamping claws 4 are used to press the material above the double-axis knife roller 3 into the cutting gap between the toothed cutter discs 301. This can avoid the accumulation of materials in the knife roller frame 1. At the same time, the side clamping claws 4 can also prevent some larger materials from splashing.

[0023] An arc-shaped pressure plate 403 is arranged on the inner side of the side clamping claw 4, and a connecting rod 401 is arranged at the bottom of the side clamping claw 4. The connecting rod 401 is connected to the side clamping claw 4 by screws, and a closing swing shaft 5 is arranged at one end of the connecting rod 401, and a reset swing shaft 6 is arranged at the other end of the connecting rod 401.

The connecting rod 401 is installed inside the lubrication shaft groove 101, and the side clamping claw 4 is connected to the rotating rod of the knife roller frame 1 through the connecting rod 401;

[0024] In this embodiment, when the side clamping claw 4 performs a clamping operation, the pulley 203 inside the electric control sleeve 2 at the other end of the knife roller frame 1 will be pulled upward by the tensioning belt 201. When the side clamping claw 4 needs to be reset, the pulley 203 moves downward and uses the tensioning belt 201 to drive the reset swing shaft 6 to rotate counterclockwise until the side clamping claw 4 returns to a vertical state.

[0025] Working principle: the side clamping claws 4 are distributed on both sides of the double-axis knife roller 3. The material is put in from the top of the knife roller frame 1. The pulley 203 inside the electric control sliding sleeve 2 at one end of the knife roller frame 1 moves downward, and the closing swing shaft 5 is driven to rotate clockwise through the tensioning pull belt 201. When the closing swing shaft 5 rotates inward, it will drive the side clamping claws 4 on both sides to flip in the same direction, and use the side clamping claws 4 to press the material above the double-axis knife roller 3 into the cutting gap between the toothed cutter discs 301, so that It can prevent materials from accumulating in the knife roller frame 1. At the same time, the side clamping claw 4 can also prevent some larger materials from splashing. When the side clamping claw 4 performs the clamping operation, the pulley 203 inside the electric control sleeve 2 at the other end of the knife roller frame 1 will be pulled upward by the tensioning belt 201. When the side clamping claw 4 needs to be reset, the pulley 203 moves downward and uses the tensioning belt 201 to drive the reset swing shaft 6 to rotate counterclockwise until the side clamping claw 4 returns to a vertical state.
