[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Example 1: Please refer to Figures 1-5 The present invention provides the following technical solution: a waste crushing and recycling machine for plastic corrugated tube production and processing, comprising a crushing box 1 for crushing and processing waste from plastic corrugated tube production, an installation frame 2 fixed on the outside of the crushing box 1 and supported on the ground, a recycling conveyor line 3 installed on the installation frame 2 and located below the crushing box 1, a distribution box 4 for diverting waste of different sizes installed above the crushing box 1, a feed hopper 5 for controlling the feeding of waste installed above the distribution box 4, and a triangular guide plate 51 for diverting waste to both sides fixed in the feed hopper 5; two sets of crushing rollers 11 are rotatably installed in the crushing box 1, and a guide channel 9 for guiding small particles of waste is fixed on the inner wall of the distribution box 4 and the crushing box 1; a diversion mechanism for screening and diverting small particles of plastic corrugated tube production waste is provided inside the crushing box 1, and a buffer mechanism for guiding the waste to make smooth contact with the crushing rollers 11 is provided in the crushing box 1.

[0040] Please see Figures 2-4 The diversion mechanism includes a mounting base 6 fixed to the inner wall of the distribution box 4. A sorting plate 7 is rotatably connected to the mounting base 6. Two sorting plates 7 are symmetrically arranged about the triangular guide plate 51. The sorting plates 7 are inclinedly arranged above the guide channel 9, and a screen 8 is embedded and fixed in the sorting plate 7. The opening of the guide channel 9 is located directly below the screen 8. The lower opening of the guide channel 9 is located on the side of the crushing roller 11, and a vertical plate 10 is fixed on the side of the guide channel 9 to guide large pieces of waste to contact the crushing roller 11. A protective plate 12 is fixed on the side of the guide channel 9 near the crushing roller 11, and the protective plate 12 is positioned above the crushing roller 11 for protection.

[0041] Please see Figures 4-11The buffer mechanism includes a movable frame 13 that is laterally slidably disposed inside the crushing box 1. The movable frame 13 is disposed between the vertical plate 10 and the crushing roller 11. Multiple pressure plates 14 are disposed in the movable frame 13 to buffer the impact force of falling large pieces of waste. A support frame 131 is fixed next to the flow channel 9. A guide rail 132 is fixedly installed on the support frame 131. A slide block 133 is slidably installed on the guide rail 132. The slide block 133 is fixedly installed on the movable frame 13. An electric telescopic rod 134 is fixedly fixed to the inner wall of the crushing box 1. A positioning block 135 is fixed to the telescopic end of the electric telescopic rod 134. The positioning block 135 is fixedly installed on the movable frame 13. A cylindrical seat 141 is fixed to the inner wall of the movable frame 13. A rotating shaft 142 is rotatably connected through the cylindrical seat 141. A rotating cylinder 143 is fixed along the central axis on the rotating shaft 142. A pressure plate 14 is fixedly connected to the rotating cylinder 143. A spiral spring 144 is elastically connected between the inner wall of the cylindrical seat 141 and the rotating shaft 142. The pressure plate 14 is positioned directly above the two sets of crushing rollers 11, and two adjacent sets of pressure plates 14 are closed directly below the two sets of vertical plates 10.

[0042] Waste from the production of plastic corrugated tubing is fed into the feed hopper 5. After initial guidance by the triangular guide plate 51, the waste is directed to both sides of the feed hopper 5 and falls onto the sorting plate 7. Through the sorting action of the inclined sorting plate 7 and the screen 8, small pieces of waste pass through the screen 8 and enter the lower guide channel 9. Guided by the guide channel 9, these small pieces do not directly contact the crushing roller 11, reducing the cutting load on the crushing roller 11. Large pieces of waste are guided from the surface of the sorting plate 7 to the middle area of ​​the distribution box 4. These large pieces concentrate between the two sets of vertical plates 10 and fall freely downwards, contacting the pressure plate 14. The pressure plate 14 provides contact buffering, reducing the impact on the large pieces of waste. The pressure plate 14 rotates downward under pressure due to the falling speed and impact force. When two adjacent sets of pressure plates 14 rotate downward and open, they form a downward-opening channel, allowing large pieces of waste to fall onto the crushing roller 11 at a slower speed. This avoids problems such as tooth breakage and blade fatigue caused by instantaneous impact on the crushing roller 11, thus extending the service life of the crushing roller 11. When the pressure plate 14 rotates, it drives the rotating drum 143 and the rotating shaft 142 to rotate synchronously. When the pressure on the surface of the pressure plate 14 disappears, the rotating shaft 142 rotates and resets under the elastic action of the spiral spring 144, causing the pressure plate 14 to rotate upward and be horizontally aligned directly above the crushing roller 11, so as to buffer the subsequent large pieces of waste.

[0043] A motor is fixed outside the crushing box 1 to drive one set of crushing rollers 11 to rotate. Gears are fixed on both sets of crushing rollers 11 along the central axis. The gears on the two sets of crushing rollers 11 mesh with each other. When one set of crushing rollers 11 rotates under the drive of the motor, it drives the other set of crushing rollers 11 to rotate in the opposite direction under the transmission of the meshing gears. The blades of the two sets of crushing rollers 11 bite each other to achieve the purpose of crushing and processing waste materials from the production of plastic corrugated tubes. After being crushed, the waste materials are collected with the waste materials in the guide channel 9 and then fall onto the surface of the recycling conveyor line 3 after being discharged from the crushing box 1. The waste materials are then transported outwards for recycling and reuse through the recycling conveyor line 3.

[0044] Example 2: Please refer to Figures 11-14 Based on Embodiment 1, a shaking mechanism is also disclosed, the specific structure of which is as follows: A shaking mechanism for driving the sorting plate 7 to reciprocate at a small frequency is provided in the flow channel 9. The shaking mechanism includes a lifting frame 15 that is longitudinally slidably connected in the flow channel 9, and a lower U-shaped seat 19 is fixed on the upper end face of the lifting frame 15; an upper U-shaped seat 20 is fixed on the lower surface of the sorting plate 7, and a push rod 21 is rotatably connected to the upper U-shaped seat 20, the other end of the push rod 21 being rotatably connected to the lower U-shaped seat 19. Multiple upper transmission frames 16 are fixed at equal intervals laterally on the lifting frame 15, and multiple lower transmission frames 17 are fixed at equal intervals laterally in the moving frame 13. A transmission rod 18 is rotatably mounted on the lower transmission frame 17, and the other end of the transmission rod 18 is rotatably connected to the upper transmission frame 16.

[0045] The electric telescopic rod 134 drives the positioning block 135 to move laterally and reciprocate. The positioning block 135 is fixed on the moving frame 13. The positioning block 135 drives the moving frame 13 to move laterally and reciprocate synchronously. The slide block 133 on the side of the moving frame 13 engages with the guide rail 132 and slides to keep the moving frame 13 moving horizontally. When the moving frame 13 moves laterally, the sorting plate 7 moves laterally and reciprocates on the crushing roller 11, so that the large pieces of waste buffered on the sorting plate 7 are evenly spread on the entire length of the crushing roller 11. This avoids local overload and uneven wear of the crushing roller 11. The uniform feeding makes the cutting load of the crushing roller 11 more stable, reduces motor current fluctuations, and improves crushing efficiency and uniformity of output particle size.

[0046] While the moving frame 13 reciprocates laterally, it drives the lower transmission frame 17 to move laterally synchronously. At this time, the two ends of the transmission rod 18 connected between the lower transmission frame 17 and the upper transmission frame 16 rotate accordingly. The transmission rod 18 can drive the upper transmission frame 16 to reciprocate longitudinally. The upper transmission frame 16 is fixed on the lifting frame 15, driving the lifting frame 15 to move longitudinally through the guide channel 9. The upper U-shaped seat 20 at the upper end of the lifting frame 15 moves longitudinally synchronously. At this time, the two ends of the push rod 21 connected between the upper U-shaped seat 20 and the lower U-shaped seat 19 rotate accordingly. The rotating push rod 21 pushes the upper U-shaped seat 20 to move, thereby driving the sorting plate 7 connected to the mounting base 6 to reciprocate at a low frequency, accelerating the sorting of large and small pieces of waste on the sorting plate 7, and preventing some small pieces of waste from clogging the mesh of the screen 8, keeping the waste sorting fast and smooth.

[0047] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0048] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
