[0025] Please refer to Figures 1-6As shown, this utility model is a combination blade and claw type waste plastic crusher, including a machine body 10, which is placed on the ground by a support column. A feed hopper 11 for feeding is installed through the top of the machine body 10, and a discharge chute 12 for discharging is installed through the side of the machine body 10. A drive motor is provided on one side of the machine body 10. A crushing assembly is set in the cavity of the machine body 10. The crushing assembly includes a first cylindrical plate 14 and a second cylindrical plate 15 that are limited and fixed in the cavity of the machine body 10. A crushing blade unit and a crushing claw unit are arranged between the first cylindrical plate 14 and the second cylindrical plate 15. The crushing blade unit includes a circular blade 17, a fixed blade component 18 and a rotating shaft 19. The fixed blade component 18 includes an installation strip 23 and a blade 24. The blade 24 has an installation cavity 25 at equal intervals on the side near the main shaft 13. The crushing claw unit includes a crushing claw 16, a main shaft 13 and an inclined blade 26, which is installed in the corresponding installation cavity 25.

[0026] Specifically, waste plastic parts enter the machine body 10 cavity through the feed hopper 11. By setting up a crushing component, the circular blade 17 crushes the waste plastic parts during rotation. The crushing claw 16 cooperates with the fixed blade component 18 to further crush the crushed plastic parts into smaller particles. The circular blade 17 moves through the gap between two adjacent sets of crushing claws 16 below, further crushing the plastic particles in the gap, avoiding plastic particles from getting stuck between the two sets of crushing claws 16. The crushing blade unit and the crushing claw unit cooperate with each other, which helps to improve the crushing efficiency of the device.

[0027] Among them, such as Figures 1-2 As shown, the main shaft 13 is movably installed in the cavity of the machine body 10. The main shaft 13 movably passes through the first cylindrical plate 14 and the second cylindrical plate 15. A driven wheel is fixedly installed at one end of the main shaft 13, and a driving wheel is fixedly installed at the output end of the drive motor. A belt is sleeved between the driving wheel and the driven wheel.

[0028] Specifically, during operation, the drive wheel at the output end of the drive motor rotates through the driven wheel at one end of the main shaft 13 via the belt drive, thereby driving the main shaft 13 to rotate. The crushing claw 16 is fixedly installed on the outer wall of the main shaft 13, and the main shaft 13 drives the crushing claw 16 to rotate synchronously.

[0029] Among them, such as Figure 3 As shown, the axis of the main spindle 13 coincides with the axis of the first cylindrical plate 14 and the second cylindrical plate 15. The circular blades 17 are located directly above the main spindle 13. There are multiple sets of circular blades 17, and the rotating shaft 19 moves through the center of the multiple sets of circular blades 17.

[0030] By setting the axis of the main spindle 13 to coincide with the axis of the first cylindrical plate 14 and the second cylindrical plate 15, the circular blades 17 are located directly above the main spindle 13. There are multiple sets of circular blades 17, and the rotating shaft 19 moves through the center of the multiple sets of circular blades 17. During the rotation, the circular blades 17 break the plastic parts into multiple parts, completing the preliminary processing of the plastic parts.

[0031] One end of the main shaft 13 is fixedly connected to the first gear 20, and one end of the rotating shaft 19 is movably connected to the second cylindrical plate 15 and fixedly connected to the second gear 21. The second gear 21 is movably meshed with the first gear 20. The rotating shaft 19 and the main shaft 13 are movably engaged with the limit reinforcement box 22. The other end of the rotating shaft 19 is movably installed on one side of the first cylindrical plate 14.

[0032] Specifically, a first gear 20 is fixedly inserted through one end of the main shaft 13, and a second gear 21 is fixedly inserted through one end of the rotating shaft 19 through the second cylindrical plate 15. The second gear 21 meshes with the first gear 20. The rotation of the main shaft 13 drives the rotation of the rotating shaft 19 by transmitting the first gear 20 to the second gear 21. The rotating shaft 19 drives multiple sets of circular blades 17 to rotate. The stability of the device is further improved by setting a limit reinforcement box 22.

[0033] Among them, such as Figure 4 As shown, the crushing claw 16 is fixedly installed on the outer wall of the main shaft 13. The crushing claw 16 is spirally distributed on the outer wall of the main shaft 13, and the circular blade 17 moves through the gap between two adjacent sets of crushing claws 16 below.

[0034] Specifically, by setting the crushing claws 16 to be spirally distributed on the outer wall of the main shaft 13, the crushing claws 16 rotate with the main shaft 13. When the top of the crushing claws 16 passes the fixed blade component 18, the plastic parts are crushed. By setting the crushing claws 16 to be spirally distributed on the outer wall of the main shaft 13, the crushing effect is better. By setting the circular blade 17 to move through the gap between two adjacent sets of crushing claws 16, the circular blade 17 can crush the plastic parts between the two sets of crushing claws 16, avoiding the plastic parts from getting stuck in the gap, and also improving the crushing efficiency.

[0035] Among them, such as Figures 5-6 As shown, the mounting strip 23 is fixedly installed between the first cylindrical plate 14 and the second cylindrical plate 15. The cutter 24 is fixed to the mounting strip 23 by screws. The oblique cutter part 26 movably passes through the gap between two adjacent sets of crushing claws 16 on one side. The oblique cutter part 26 includes a cutter body 28 and a rectangular block 27. A threaded hole 30 is opened on one side of the rectangular block 27. The rectangular block 27 is fixed to the cutter 24 by screws. The cutter body 28 is installed on the top of the rectangular block 27. A support block 29 is also fixedly installed between the cutter body 28 and the rectangular block 27. The support block 29 is a right-angled triangle, and the cutter body 28 is a "slanted cone" shape.

[0036] Specifically, the installation strip 23 is fixedly installed between the first cylindrical plate 14 and the second cylindrical plate 15, and the cutter 24 is fixed on the installation strip 23. During the crushing operation, the cutter 24 works with the crushing claw 16 to crush the plastic parts. The rectangular block 27 is installed in the installation cavity 25 by screws, and the cutter body 28 is fixedly installed on the rectangular block 27. The cutter body 28 is in the shape of an "oblique cone". The cone tip of the cutter body 28 preferentially becomes the stress concentration point, which controls the fracture initiation position, reduces the energy required for plastic fracture, and further improves the crushing efficiency.

[0037] The specific working principle of this utility model of a blade-claw combined waste plastic crusher is as follows: Waste plastic parts enter the machine body 10 cavity through the feed hopper 11. A crushing assembly is installed, and the circular blade 17 crushes the waste plastic parts during rotation. The blade 24 is fixed on the mounting strip 23. During crushing, the blade 24 works with the crushing claw 16 to crush the plastic parts. A rectangular block 27 is installed in the mounting cavity 25 by screws. The blade body 28 is fixedly installed on the rectangular block 27. The blade body 28 is in the shape of an oblique cone, and the cone tip of the blade body 28 preferentially becomes the stress concentration point, controlling the fracture initiation position. The arrangement of the crushing claws 16 on the outer wall of the main shaft 13 reduces the energy required for plastic breakage and further improves crushing efficiency. The crushing claws 16 are spirally distributed on the outer wall of the main shaft 13. The crushing claws 16 rotate with the main shaft 13. When the top of the crushing claws 16 passes the fixed blade component 18, the plastic parts are crushed. The spiral arrangement of the crushing claws 16 on the outer wall of the main shaft 13 results in better crushing effect. The circular blade 17 moves through the gap between two adjacent sets of crushing claws 16. The circular blade 17 can crush the plastic parts between the two sets of crushing claws 16, preventing the plastic parts from getting stuck in the gap, and also improving crushing efficiency.
