The inclined surface of the positioning block 81 is set on the upper front side. The shape of the positioning block 81 ensures that the falling plastic particles are not easy to fall below the positioning block 81. The outer wall of the positioning block 81 is fixedly connected to the inner wall of the machine body 1. The bottom end of the positioning block 81 is fixedly connected to an electric track 82. The electric track 82 has a slider 83 inside. The slider 83 is cuboid in shape.
[0039] Reference Figure 4 and Figure 5 The inner wall of the slider 83 is rotatably connected to a rotating rod 84, the outer wall of the rotating rod 84 is fixedly connected to a rolling roller 85, the outer wall of the rotating rod 84 is fixedly connected to a gear 86, and the inner wall of the machine body 1 is fixedly connected to a rack 87, which meshes with the gear 86.
[0040] Reference Figure 3 , Figure 6 and Figure 7The upper side of the filter plate 7 is provided with a pushing assembly 9 together with the inside of the machine body 1, the pushing assembly 9 comprises a gas pressure chamber 91, the shape of the gas pressure chamber 91 is concave, and the shape of the gas pressure chamber 91 is an axisymmetric figure consistent on the left and right, the gas pressure chamber 91 is opened in the inner wall of the machine body 1, the inside of the gas pressure chamber 91 is filled with gas, the inner wall of the gas pressure chamber 91 is connected with a piston block 92, the number of the piston block 92 is two, and the two piston blocks 92 are respectively arranged at the left and right two openings of the gas pressure chamber 91, the two piston blocks 92 are symmetrically arranged with the middle surface of the machine body 1 as the symmetry surface, the outer wall of the piston block 92 is attached to the inner wall of the gas pressure chamber 91, one end of the piston block 92 away from the middle of the machine body 1 is elastically connected with the inner wall of the gas pressure chamber 91 through a spring 93, one end of the spring 93 is fixedly connected with the one end of the piston block 92 away from the middle of the machine body 1, the other end of the spring 93 is fixedly connected with the inner wall of the gas pressure chamber 91, and the number of the spring 93 is two, the elastic forces of the two springs 93 are consistent, one end of the piston block 92 away from the spring 93 is fixedly connected with a pushing plate 94, the rear end of the pushing plate 94 is provided with a groove with a height and a depth greater than the height and the thickness of the rack 87, and the inner wall of the machine body 1 below the filter plate 7 is slidably provided with a drawer 10, and the drawer 10 can be taken out from the inside of the machine body 1.
[0041] Working principle: in use, the staff first starts the equipment, and then puts the plastic products that need to be ground into the feeding hopper 2.
[0042] At this time, the motor 6 drives the left rotating rod 3 to rotate, and drives the left gear one 5 to rotate through the left rotating rod 3, so that the left gear one 5 drives the right gear one 5 to rotate, so that the right gear one 5 drives the right rotating rod 3 to rotate, at this time, the left rotating rod 3 and the right rotating rod 3 rotate, so the grinding knife 4 outside the left and right rotating rods 3 rotates, so as to achieve the effect of grinding the plastic products.
[0043] When the grinding is completed, the ground plastic particles fall on the filter plate 7, at this time the electric track 82 drives the sliding block 83 to move reciprocatingly in the left and right directions, the sliding block 83 drives the rotating rod 84 to move left and right in the moving process, in the moving process of the rotating rod 84, since the teeth of the gear two 86 are in contact with the teeth of the rack 87, the gear two 86 cannot move directly, so the gear two 86 rotates and drives the rolling roller 85 to rotate.
[0044] Since the shape of the rolling roller 85 is a cylinder, when the rolling roller 85 rotates, it can roll the plastic powder below it, and since it transmits downward pressure to the plastic powder in the rotating process, when the particles of the plastic powder are small, they can be extruded to pass through the holes of the filter plate 7, avoiding the situation that the plastic powder is accumulated but cannot be discharged.
[0045] When the rolling roller 85 rotates to the left or right edge, at this time for the convenience of description, it is assumed that the rolling roller 85 moves from left to right and moves to the right edge position, at this time, the rolling roller 85 pushes the right pushing plate 94 to the right, so that the right pushing plate 94 drives the right piston block 92 to move to the direction of the entering air pressure chamber 91, so that the left piston block 92 moves to the right under the action of air pressure, so as to push the debris in the left corner to the area close to the middle.
[0046] When the rolling roller 85 moves to the edge, and then moves to the left, at this time, the right piston block 92 moves to the left under the elastic force of the right spring 93, so that the left piston block 92 moves to the left under the combined action of the elastic force of the spring 93 and the air pressure, and drives the pushing plate 94 to move to the left and reset.
