[0032] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0033] Reference Figures 1-3 A plastic recycling and crushing device includes: a crushing box 1, a primary crushing mechanism 2, a secondary crushing mechanism 3, and a synchronization mechanism 4. The primary crushing mechanism 2 and the secondary crushing mechanism 3 are arranged sequentially from top to bottom inside the crushing box 1. The secondary crushing mechanism 3 includes: a crushing roller 301 and a reciprocating feeding assembly 302. The crushing roller 301 is horizontally rotatably arranged inside the crushing box 1 through the synchronization mechanism 4. The crushing box 1 has a plurality of discharge screen holes 101 on one side of the crushing roller. The reciprocating feeding assembly 302 is arranged on one side of the crushing roller 301 and can continuously feed plastic into the crushing roller.

[0034] This application involves feeding plastic into the inlet above the crushing chamber 1. After being crushed by the primary crushing mechanism 2, the plastic falls between the crushing roller 301 and the reciprocating feeding assembly 302. The crushing roller 301 performs secondary crushing on the plastic. The qualified plastic is crushed and discharged through the discharge screen 101, while the unqualified plastic is carried back to the reciprocating feeding assembly 302 and the crushing roller 301 by the crushing roller 301. The reciprocating feeding assembly 302 then feeds the plastic back into the crushing roller 301 for crushing, and the qualified plastic is crushed and discharged through the discharge screen 101 again. Through this crushing method, unlimited crushing can be achieved until all the plastic is crushed and discharged through the discharge screen 101, thereby precisely controlling the particle size and improving the crushing effect.

[0035] Reference Figure 7 The crushing and rolling roller is provided with a first crushing block 30101 and a strip-shaped rolling block 30102 coaxially spaced around its periphery.

[0036] During the rotation of the crushing and pressing roller of this application, the first crushing block 30101 will crush the plastic. The crushed plastic will be thrown to the discharge screen hole 101 under the action of centrifugal force. Then, when the pressing block rotates to the discharge screen hole 101, the crushed plastic will be crushed out of the discharge screen hole 101.

[0037] Reference Figure 4 The reciprocating feeding assembly 302 includes a pusher block 30201 and a drive assembly 30202. The pusher block 30201 is reciprocally movable on one side of the crushing and rolling roller 301 via the drive assembly 30202.

[0038] This application uses the start drive assembly 30202 to drive the pusher block 30201 to move back and forth on one side of the crushing and rolling roller 301, thereby continuously feeding plastic into the crushing and rolling roller 301.

[0039] Reference Figure 6 The pusher block 30201 is provided with a second crushing block 3020101 that is adapted to the first crushing block 30101 on the side near the crushing and rolling roller 301.

[0040] Through this design, the plastic can be further crushed by the cooperation of the first crushing block 30101 and the second crushing block 3020101 during the reciprocating movement of the pusher block 30201, thereby improving the crushing efficiency.

[0041] Reference Figure 5 and Figure 6 The drive assembly 30202 includes a first drive motor 3020201, a rotating connecting rod 3020202, and a connecting rod 3020203. The first drive motor 3020201 is disposed on one side of the crushing box 1, and its output shaft is coaxially disposed with one end of the rotating connecting rod 3020202. One end of the connecting rod 3020203 is hinged to the outer end of the rotating connecting rod 3020202, and the other end is hinged to the outer side of the pusher block 30201.

[0042] This application starts the first drive motor 3020201 to drive the rotating connecting rod 3020202 to rotate, thereby driving the pusher block 30201 to move back and forth continuously through the connecting rod 3020203.

[0043] Reference Figure 2 and Figure 3 The crushing box 1 has a ramp 102 located on one side of the crushing roller 301, and the reciprocating feeding assembly 302 is inclined on the ramp 102.

[0044] This application ensures that the plastic will slide between the crushing and crushing roller 301 and the reciprocating feeding assembly 302 under the action of gravity by setting the ramp 102 and the inclined reciprocating feeding assembly 302, so as to facilitate crushing and crushing.

[0045] Reference Figure 2 and Figure 3 The crushing box 1 is equipped with a baffle 103 located below the primary crushing mechanism 2 and tilted towards the crushing and grinding roller 301.

[0046] This application sets up a baffle 103 to ensure that after the plastic is crushed by the primary crushing mechanism 2, it will slide down between the crushing and rolling roller 301 and the reciprocating feeding assembly 302 under the action of the baffle 103, so as to facilitate crushing and rolling.

[0047] Reference Figure 4 The primary crushing mechanism 2 includes: a first crushing roller 201, a second crushing roller 202, a second drive motor 203, and a synchronous gear 204. The first crushing roller 201 and the second crushing roller 202 are spaced apart at the feed inlet of the crushing box 1, and they are respectively coaxially provided with a synchronous gear 204 that meshes with each other at the same end. The second drive motor 203 is located on one side of the crushing box 1 and can drive the first crushing roller 201 or the second crushing roller 202 to rotate.

[0048] This application achieves the first step of crushing plastic by starting the second drive motor 203 to drive the first crushing roller 201 or the second crushing roller 202 to rotate, thereby driving the other crushing roller to rotate synchronously through the synchronous gear 204.

[0049] Reference Figure 5 The synchronization mechanism 4 includes a first synchronization pulley 401, a second synchronization pulley 402, and a synchronization belt 403. The first synchronization pulley 401 is coaxially arranged at one end of the first crushing roller 201 or the second crushing roller 202, and the second synchronization pulley 402 is coaxially arranged at one end of the crushing and rolling roller 301. The two ends of the synchronization belt 403 are respectively sleeved on the first synchronization pulley 401 and the second synchronization pulley 402.

[0050] This application starts the second drive motor 203 to drive the first crushing roller 201 or the second crushing roller 202 to rotate, thereby driving the other crushing roller to rotate synchronously through the synchronous gear 204, and then driving the crushing and rolling roller 301 to rotate synchronously through the synchronous belt 403.

[0051] Reference Figure 1 The crushing box 1 is provided with a conveying mechanism 5 on the side near the discharge screen hole 101 to transport the crushed plastic to the next stage.

[0052] This application improves recycling efficiency by setting up a conveying mechanism 5 to directly transport the plastic crushed from the discharge screen hole 101 to the next processing stage.

[0053] In use, the device provided by this utility model involves feeding plastic into the feed inlet above the crushing box 1. After being crushed by the primary crushing mechanism 2, the plastic falls between the crushing roller 301 and the reciprocating feeding assembly 302. The crushing roller 301 performs secondary crushing on the plastic. The qualified plastic is crushed and discharged through the discharge screen 101. The unqualified plastic is carried back to the reciprocating feeding assembly 302 and the crushing roller 301 by the crushing roller 301. Then, the reciprocating feeding assembly 302 feeds the plastic back into the crushing roller 301 for crushing, and the qualified plastic is crushed and discharged through the discharge screen 101 again. Through this crushing method, unlimited crushing can be achieved until all the plastic is crushed and discharged through the discharge screen 101, thereby precisely controlling the size of the crushed particles and improving the crushing effect.
