However, waste is inevitable during use. If plastic products are not handled correctly, they will pollute the environment and violate the theme of energy conservation and environmental protection. According to the characteristics of plastic materials, plastic materials are usually crushed by cutting and crushing.

[0003] In the prior art, during the cutting and crushing process of plastic materials, the plastic materials are usually placed in a crusher, and then the crushed debris falls into a collection box through a filter placed under the crusher, and the plastic materials that do not meet the size standards stay on the filter to facilitate working again.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In the present invention, when the device is used, the staff first places the plastic material in the driving component for cutting and crushing.

When it is necessary to crush large plastic materials, the control component is operated to drive the two extrusion components to work synchronously, so that the plastic material is located between the two extrusion components and compressed. While the extrusion component is working, the twisting component and the crushing component are inserted into the plastic material through the matching component, and the plastic material is twisted and crushed from the inside, so that the plastic material is decomposed into a number of small plastic materials that fall into the driving component and then crushed.

[0014] In the present invention, the staff first controls the driving motor to rotate, thereby driving the rotating shaft to rotate, and then driving the two crushing rollers to rotate in opposite directions, and then places the plastic material into the feed channel through the through-hole, so that it can pass through the two crushing rollers to complete the crushing work. While the driving motor is working, the central axis is synchronously driven to rotate through the set transmission belt, thereby causing the filter frame to vibrate, so that the crushed plastic material can quickly pass through the filter frame and fall into the collection box. While increasing the collection speed, it avoids the large volume of plastic materials staying on the filter screen during the falling process to cause blockage of the filter screen, thereby avoiding affecting the discharge speed and improving the practicality of the device.

[0015] In the present invention, when large plastic materials need to be crushed, the electric push rod is controlled to work, thereby driving the two control frames to approach each other on the control sliding seat, and then driving the first moving blocks in the two rectangular frames to move in the direction of the through-hole, so that the two extrusion members are close to each other to compress the plastic material.

In this process, it is avoided that a long time of work is required to completely crush the large plastic material, and the working time is reduced, thereby improving the crushing efficiency.

[0040] When it is necessary to crush large plastic materials, the electric push rod 62 is controlled to work, thereby driving the sliding frame 63 to move on the top of the receiving frame 61 toward the driving frame 21, and the direction of the sliding frame 63 is limited by the first telescopic rod 64, so that under the action of the two control rods 67, the two control frames 66 are driven to approach each other on the control sliding seat 65, and then the first moving blocks 712 in the two rectangular frames 711 are driven to move toward the through-opening 23 through the L-shaped connecting frame 713, so that under the action of the trigger rod 716, the two extruding members 715 are driven to approach each other and respectively contact one side of the plastic material to compress the plastic material. In the process of compression, the pressing rod 722 and With the cooperation of the oblique groove 723, the second moving block 721 is driven to slide along the side end of the first moving block 712, so that the end of the driving rod 725 is pressed against the end of the driving rod 725 by the oblique setting, so that it slides along the reference frame 714 in the direction of the plastic material, and the reset spring 727 is contracted by the driving disk 726, so that the torsion rod 82 and the blocking block 90 are synchronously driven to move along the direction of the moving groove 88 under the action of the clamping rod 84 and the arc-shaped sliding groove 83, so that the several L-shaped blades 105 gathered together are inserted into the plastic material through the fixing sleeve 103 under the action of the second telescopic rod 102. At this time, the second telescopic rod 102 will first extend to the extreme, and in the process of continuous movement, the pull rod 106 drives several The connecting frames 104 move away from each other, thereby driving the several L-shaped blades 105 to move away from each other. When the two blocking blocks 90 move from the first annular groove 86 to the second annular groove 87 through the moving groove 88, the side ends of the blocking blocks 90 abut against the inner wall of the second annular groove 87. Since the driving rod 725 continues to move along the torsion rod 82 at this time, the blocking rod 84 cooperates with the arc-shaped slide groove 83, and the torsion rod 82 rotates in the connecting groove 81. Through the cooperation of the rotating disk 101 and the annular sleeve 85, the several unfolded L-shaped blades 105 rotate synchronously, so that they are twisted and crushed from the inside during the rotation process, and through the two torsion components 8, the L-shaped blades 105 on both sides rotate in opposite directions. Thereby, it is decomposed into several small plastic materials which fall into the driving component 2 and are then crushed. In this process, it is avoided that a long time of work is required to completely crush the large plastic material, and the working time is reduced, thereby improving the crushing efficiency. After the crushing is completed, the first moving block 712 is driven to reset by controlling the electric push rod 62. Under the action of the reset spring 727, the driving rod 725 is reset, driving several L-shaped blades 105 to move closer to each other, and driving the two positioning blocks 90 to move into the second annular groove 87 and rotate in the opposite direction for one circle to complete the reset. At this time, the second moving block 721 is synchronously reset under the action of the pressure rod 722, which is convenient for the next work, thereby further improving the convenience of the device when used.
