[0002] In the field of plastic recycling and processing, plastic crusher is one of the key equipment. However, there are some problems that need to be solved in the operation of existing plastic crushers.

[0003] First, the problem of screen deformation: during the crushing operation, the screen will gradually deform due to the continuous squeezing of the plastic material; however, the existing technology does not fully consider the effective detection method of screen deformation in the equipment design. This deformation is difficult to detect in time, which leads to uneven size of the crushed plastic particles, affecting the product quality and the stability of subsequent processing;

[0004] Second, the screen clogging phenomenon: the complexity and diversity of plastic raw materials, such as sticky plastics, excessive feed volume, inappropriate plastic size and mixed impurities, can easily cause the screen to be clogged. If the plastic in the screen holes is not cleared before the next crushing, the subsequent crushing efficiency will be reduced, energy consumption and costs will be increased, and the wear of other parts of the equipment will be accelerated, shortening the overall service life of the equipment.

[0005] Therefore, the present invention proposes an environmentally friendly renewable plastic particle preparation device which can adapt to the size and curvature of the screen to be detected; can detect the curved surface of the screen to determine whether it is deformed; and can vibrate the screen during detection to prevent broken plastic parts from clogging the screen holes and affecting the upcoming plastic crushing work, so as to solve the above problems.

[0078] Further examples:

[0079] Please refer to Figure 1 , Figure 2 , Fig. 9 , Fig.11 , Fig.12 As shown:

[0080] The vibration anti-blocking component 6 is mainly used for vibrating the screen 3 to prevent the broken plastic parts from being blocked in the screen holes and affecting the upcoming plastic crushing work. A rotating part 601 is rotatably connected in the sliding part 501. A groove 602 is provided on the rotating part 601. A through groove is provided on the sliding part 501.

[0081] in:

[0082] The vibration anti-blocking component 6 is mainly used to vibrate the screen 3 to prevent the broken plastic parts from clogging the screen holes and affecting the upcoming plastic crushing work; at the same time, the vibration will remove the plastic particles clogging the screen holes, which is also beneficial to the deformation detection work of the screen 3.

[0083] The rotating member 601 has a rough surface and can rotate while in contact with the screen 3 .

[0084] The vertical plane where the vibration member 605 is located is on the same plane as the vertical plane where the groove 602 is located. Fig.11 .

[0085] Everything in the above example works like this:

[0086] In the initial state:

[0087] The magnetic sealing piece A201 is magnetically attracted to the crushing frame 1 to block the vertical groove 101, and the magnetic sealing piece B202 is magnetically attracted to the crushing frame 1 to block the horizontal groove 102; the spring body A406 is not stretched, the outward expansion column 407 is not inserted into the inner recessed groove 405, and the relative position of the inner column cavity 402 and the outer column cavity 404 is movable at this time; the spring body B503 is not stretched, the feedback piece 504 and the standard strip set on the sliding piece 501 coincide with each other, and the vibration piece 605 does not hit the screen 3.

[0088] The following is the working process of adaptive component 4:

[0089] When in use, first open the magnetic sealing member A201 and the magnetic sealing member B202 which are magnetically attracted to the crushing frame 1, move the hinged member 401 connected to the sliding member 501 to the bottom end of the screen standard member 301, and press it against the curved surface of the screen standard member 301. Further, after the fit is completed, fill the gas injection pipe 411 with gas through an external air pump. With the addition of gas, refer to the attached Fig. 9 And attached Fig.10 , the gas entering the inner column cavity 402 from the gas injection pipe 411 will gradually push the sliding disc 408 therein, and the disc 408 will move with the connecting rod 409 in the direction away from the gas injection pipe 411 and push the outer expansion column 407 in the guide cylinder 403 through the truncated table 410 thereon. At this time, the spring body A406 is compressed. Further, during the movement of the outer expansion column 407, the top of the outer expansion column 407 will gradually approach and finally enter the inner recessed groove 405 opened in the inner cavity of the outer column cavity 404. At this time, the relative positions of the outer column cavity 404 and the inner column cavity 402 are fixed. Furthermore, by The inner column cavity 402 and the outer column cavity 404 are the rotating parts linking the adjacent hinges 401, so that the chain body composed of the hinges 401, which is tightly attached to the screen standard part 301 during the gas injection, is in a state of being unable to deform. Furthermore, at this time, the operator injects the detection solution medium into the feedback tube 502 through the solution filling port 505, and observes the pushed feedback piece 504. When it is aligned with the standard strip on the sliding piece 501 of the transparent material, the filling work is stopped, and the adaptive component 4 completes the adaptation work of the screen standard part 301, and can be used to detect the screen 3 that has been used many times;

[0090] Furthermore, through the setting of the adaptive component 4, there is no need to prepare a separate detection device for each specific specification of the screen 3, which greatly reduces the preparation time before detection, thereby significantly improving the overall efficiency of the deformation detection of the plastic screening machine screen 33; and reduces the manpower cost and time cost caused by frequent replacement of detection devices due to different specifications, making the detection process more compact and coherent, avoiding detection interruptions and delays caused by adaptation problems, and facilitating flexible deployment and use between different detection sites and detection needs, thereby improving the utilization rate of the device.

[0091] Please refer to the above working process Figure 1 , Figure 4 , Figure 5 , Figures 8 to 10 .

[0092] The following is the working process of the screen deformation feedback component 5:

[0093] When in use, the operator pulls the sliding member 501 to drive the chain body composed of the hinge 401 to start moving with the transverse groove 102 as the guide. During the movement, the detection water pipe 506 injected with the solution on the hinge 401 will always be close to the bottom surface of the screen 3. Furthermore, if the screen 3 is bulged and deformed due to the squeezing of the plastic parts in the early use, the solution in the detection water pipe 506 passing through the detection water pipe 506 will be squeezed from the detection water pipe 506 into the feedback pipe 502, and thereby push the feedback sheet 504 therein. At this time, the feedback sheet 504 is no longer aligned with the standard strip on the sliding member 501. At this time, the operator can understand that the screen 3 is deformed by observation.

[0094] Furthermore, driven by the multiple hinges 401 that adapt to the fitting of the screen 3, the detection water pipe 506 on the hinge 401 will be squeezed, and the squeezed detection water pipe 506 will cause the solution therein to flow to a specific position, namely the feedback pipe 502, so as to feedback the deformation of the screen 3. This design can accurately adapt to various specifications of plastic screening machine screens 3, thereby improving the versatility of detection. Secondly, the solution flow feedback method has high sensitivity and can capture subtle deformation differences, providing more accurate data support for the quality evaluation of screens 3 of different specifications.

[0095] Please refer to the above working process Figures 1 to 7 .

[0096] The following is the working process of the vibration anti-blocking component 6:

[0097] Furthermore, when the hinge 401 moves on the bottom surface of the screen 3, the rotating member 601 in the through groove of the hinge 401 will rotate under the friction of the bottom surface of the screen 3. Fig.11 , Attachment Fig.12 , and since it is known that the vertical surface where the vibration member 605 is located is on the same plane as the vertical surface where the groove 602 is located, during the rotation of the rotating member 601, the vibration member 605, which was originally restricted by the circumferential surface of the rotating member 601 through the middle protrusion of the vibration member 605, will now move into the groove 602 with the rotation of the rotating member 601 and with the assistance of the spring body C606 on the bottom stabilizing rod 607, and be restricted by the auxiliary column rod 603 therein, at this time, the vibration member 605 will move upward under the guidance of the guide rod 604, thereby knocking and vibrating the bottom surface of the screen 3; further, as the rotating member 601 continues to move, the middle protrusion of the vibration member 605 will contact the circumferential surface of the rotating member 601 again, and move downward again under the resistance of the rotating member 601, so as to reciprocate and make the vibration member 605 vibrate and knock the screen 3;

[0098] Furthermore, the arrangement in which the rotating member 601 rotates due to passive friction with the screen 3 to indirectly drive the vibration anti-blocking component 6 to work, this non-electrically driven design makes it extremely versatile and can be easily applied to plastic screening occasions of various scales and working environments. It does not require complicated electrical equipment and lines, reduces potential failure points, and improves the reliability and stability of the device. Furthermore, since the device uses vibration screening, it can adapt to plastic screening machine screens 3 of different specifications and materials. Regardless of the aperture size and mesh area of ​​the screen 3, it can effectively perform vibration cleaning to prevent blockage.
