[0035] Example 1

[0036] Reference Figure 1-5 A plastic recycling and processing crushing equipment is used in the crushing process of recycled plastics to improve the crushing effect and efficiency of recycled plastics and avoid subsequent screening.

[0037] The plastic recycling and processing crushing equipment includes a shell 1, a rotating roller 6, a screen 13, a spring 14, multiple first protrusions 18, multiple second protrusions 19, and a drive motor 3;

[0038] The top of the outer shell 1 is provided with a feed port. The rotating roller 6 is vertically rotatably installed inside the outer shell 1. A support frame 11 is fixedly connected inside the outer shell 1. The middle part of the support frame 11 is rotatably connected to the top of the rotating roller 6. A fixed box 2 is provided at the bottom of the inner shell 1. A drive motor 3 is provided inside the fixed box 2. A transmission shaft 4 is provided on the output shaft of the drive motor 3. A rotating rod 5 is fixedly connected to the bottom of the rotating roller 6. The rotating rod 5 is fixedly connected to the transmission shaft 4. The drive motor 3 drives the transmission shaft 4 to rotate, thereby driving the rotating roller 6 to rotate vertically through the rotating rod 5.

[0039] Multiple cutting blade groups are equidistantly arranged vertically on the outside of the rotating roller 6. Each cutting blade group includes multiple first blades 7, which are equidistantly arranged in a ring along the outer wall of the rotating roller 6, and the cutting edges of each first blade 7 are horizontally arranged. Multiple auxiliary blade groups are equidistantly arranged vertically on the inner wall of the outer shell 1. Each auxiliary blade group includes multiple second blades 8, which are equidistantly arranged in a ring along the inner wall of the outer shell 1. The multiple cutting blade groups and the multiple auxiliary blade groups are interspersed. A stop block 10 is provided at the top of the rotating roller 6. The top of the stop block 10 is arc-shaped, which allows the recycled material that has been crushed by the two crushing rollers 9 to fall onto the first blades 7 and the second blades 8. The first blades 7, which rotate with the rotating roller 6, cooperate with the fixed second blades 8 to generate relative movement between the first blades 7 and the second blades 8. Since the cutting edges of the first blades 7 and the second blades 8 are arranged opposite each other, the falling recycled material can be cut and crushed.

[0040] A fixed plate 16 is fixedly connected to the lower end of the rotating rod 5. Each second protrusion 19 is equidistantly arranged in a ring at the bottom of the fixed plate 16, with the bottom of each second protrusion 19 being inclined. The screen 13 is vertically slidably disposed inside the outer casing 1, located below the rotating roller 6. A movable ring 12 is provided in the middle of the screen 13, and the movable ring 12 is sleeved on the outside of the rotating rod 5, allowing the screen 13 to move up and down outside the rotating rod 5 via the movable ring 12. Two connecting rods 15 are fixedly connected to the bottom of the movable ring 12. Two sliding holes are provided on the top of the fixed box 2, and the two connecting rods 15 extend into the interior of the fixed box 2 at the two sliding holes. A movable plate 17 is fixedly connected to the bottom end of the connecting rods 15. Each first protrusion 18 is equidistantly arranged in a ring at the top of the movable plate 17. The top of block 18 is sloping, and the bottom of rotating rod 5 extends into the interior of fixed box 2. Each first protrusion 18 and each second protrusion 19 is located on the same horizontal plane. Spring 14 is set between moving ring 12 and fixed box 2. Drive motor 3 drives rotating rod 5 to rotate through transmission shaft 4, thereby driving rotating roller 6 to rotate and driving each second protrusion 19 below fixed plate 16 to rotate around the axis of rotating rod 5, so that the bottom sloping surface of each second protrusion 19 intermittently pushes each first protrusion 18 downward, thereby causing moving plate 17 to move vertically downward intermittently. Through connecting rod 15, screen 13 is pulled vertically downward intermittently, and spring 14 is intermittently compressed, thereby causing spring 14 to generate compression force intermittently. Compression force causes screen 13 to bounce upward intermittently.

[0041] Example 2

[0042] A plastic recycling and processing crushing device, in order to improve the crushing effect of the device on plastic recyclables, has two crushing rollers 9 arranged side by side at the top of the inner shell 1, with a rotating roller 6 located below the two crushing rollers 9. A motor (not shown in the figure) is provided on the outside of the shell 1. The motor is connected to the crushing rollers 9 to drive them to rotate. The rotating crushing rollers 9 perform preliminary crushing on the recycled material fed into the feed port. Then, the preliminarily crushed recycled material falls onto the blades of the rotating roller 6 for further crushing, thereby improving the crushing effect.

[0043] The working principle of this plastic recycling and crushing equipment is as follows: Recycled material is fed into the feed port at the top of the outer shell 1, which enters between two crushing rollers 9. The two crushing rollers 9, driven by the motor, perform initial crushing. The initially crushed recycled material then falls between the first blade 7 and the second blade 8. At this time, the drive motor 3 drives the transmission shaft 4 to rotate, which in turn drives the rotating roller 6 to rotate vertically through the rotating rod 5. The first blade 7 rotates with the rotating roller 6, thus cooperating with the fixed second blade 8 to crush the recycled material again. The crushed recycled material continues to fall onto the screen 13 for screening.

[0044] During the crushing and screening process, the rotation of the rotating rod 5 also causes the second protrusions 19 below the fixed plate 16 to rotate around the axis of the rotating rod 5, so that the bottom inclined surface of each second protrusion 19 contacts the top inclined surface of each first protrusion 18. The inclined surfaces of the second protrusions 19 and the inclined surfaces of the first protrusions 18 slide against each other, thereby pushing the first protrusions 18 downward until the first protrusions 18 separate from the second protrusions 19. As the second protrusions 19 move continuously, the first protrusions 18 and the second protrusions 19 make intermittent contact, thereby causing the first protrusions 18 to be intermittently subjected to downward force and moving, causing the moving plate 17 to intermittently move vertically. The screen moves vertically downwards intermittently via the connecting rod 15, pulling the screen 13 vertically downwards and intermittently compressing the spring 14. This causes the spring 14 to intermittently generate compression force. During this process, when the spring 14 releases its force, it will launch the screen 13 upwards, causing the recycled material on the screen 13 to be shaken and screened, improving the screening effect. At the same time, it will also throw large pieces of recycled material upwards, causing them to re-enter between the first blade 7 and the second blade 8 for crushing. As the screen 13 intermittently launches and shakes upwards, it crushes the large pieces of recycled material on the screen 13, improving the crushing effect and crushing efficiency.

[0045] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
