[0031] Reference Figure 1-4This utility model provides an embodiment of a waste plastic recycling and crushing device, including a crushing box 1. A top cover 2 is provided on the top of the crushing box 1 for easy maintenance. Connectors 5 are fixedly connected to the front and rear ends of the top cover 2. Limiting blocks 6, hemispherical in shape, are fixedly connected to the bottom of each connector 5. Support seats 7 are fixedly connected to the front and rear ends of the crushing box 1. Sliding grooves 8 are provided on the top of each support seat 7, which limit the movement of limiting blocks 9. Two limiting blocks 9 are slidably connected within the sliding grooves 8. The limiting blocks 9 have grooves to facilitate the limiting of the hemispherical limiting blocks 6. Support plates 10 are fixedly connected to both sides of the top of the support seats 7, providing support. Pull rods 11 are slidably connected through and within each support plate 10. Two rotating rods 13 are rotatably connected through and within the upper part of the crushing box 1. Crushing rollers 14 are fixedly connected to the outer rings of the two rotating rods 13, allowing the rotating rods 13 to drive the crushing rollers 14 to rotate. A gear 15 is fixedly connected to the outer right ring of the rotating rod 13. Connecting plates 17 are fixedly connected to both sides of the lower part of the crushing box 1, serving a supporting function. Second springs 18 are fixedly connected to both sides of the top of the connecting plates 17. A screening plate 19 is fixedly connected to the top of the second springs 18. The screening plate 19 has screen holes and is slightly inclined. A vibration motor 20 is fixedly connected to the lower front end of the screening plate 19, causing it to vibrate. A discharge port 21 is located on the left side of the crushing box 1 to facilitate the discharge of incompletely crushed plastic. A collection box 23 is slidably connected through the lower right side of the crushing box 1 for collecting the crushed plastic.

[0032] The top cover 2 has a slot 3 at its bottom, and the top of the crushing box 1 is placed in the slot 3, which acts as a limit. The two pull rods 11 are fixedly connected at adjacent ends to the limiting clamps 9, allowing the pull rods 11 to move the limiting clamps 9. A feed cylinder 4 is fixedly connected through the top of the top cover 2. A first spring 12 is fitted around the outer ring of the pull rod 11, positioned between the support plate 10 and the limiting clamps 9. The first spring 12's reset allows the two limiting clamps 9 to move relative to each other. Two gears 15 are located on the outside of the crushing box 1 and mesh with each other for transmission. A motor 16 is fixedly connected to the right side of the crushing box 1, and the output end of the motor 16 is fixedly connected to the rear rotating rod 13. A mounting bracket (not shown in the figure) is installed at the bottom of the motor 16 and is fixedly connected to the crushing box 1. A collection box 22 is located on the left side of the crushing box 1, and a fixing plate (not shown in the figure) is installed on the left side of the crushing box 1, with the collection box 22 placed on the fixing plate. The collection box 22 is located below the discharge port 21.

[0033] Working principle: During use, the motor 16 is started, and its output drives the rear rotating rod 13 to rotate. The gear 15 on the outer ring of the rotating rod 13 rotates accordingly. Since the two gears 15 mesh with each other, the front rotating rod 13 also starts to rotate, thereby causing the two crushing rollers 14 to rotate relative to each other. Then, plastic is fed into the crushing box 1 from the feed cylinder 4. The two relatively rotating crushing rollers 14 squeeze and shear the fed waste plastic to crush it. At the same time, the vibration motor 20 is started, which, together with the second spring 18, causes the screening plate 19 to vibrate. The crushed plastic falls onto the screening plate 19, and the vibrating screening plate 19 screens the plastic fragments. Small fragments fall through the screening plate 19 into the collection box 23 below for collection, while fragments that are not completely crushed will pass through the inclined screening plate. 19 is discharged from the discharge port 21 on the left and enters the collection box 22 for collection. This makes it convenient for subsequent personnel to pour the incompletely crushed plastic in the collection box 22 back into the crushing box 1 from the feed cylinder 4 for secondary crushing, ensuring the crushing effect. When it is necessary to inspect the crushing box 1, pull the pull rod 11 outward to drive the limit clamp 9 to move outward along the slide 8, thereby releasing the restriction on the limit plug 6, which facilitates the quick disassembly of the top cover 2. When installing, align the slot 3 at the bottom of the top cover 2 with the top of the crushing box 1. Next, the top cover 2 is placed on the crushing box 1. At the same time, the limiting blocks 6 at the front and rear ends of the top cover 2 are inserted between the two limiting clamps 9 at the front and rear ends of the crushing box 1. At this time, the two limiting clamps 9 are squeezed and slide to both sides in the sliding groove 8. The two limiting clamps 9 squeeze the first spring 12 to both sides. After the limiting block 6 enters between the two limiting clamps 9, the first spring 12 returns to its original position, which drives the two limiting clamps 9 to move relative to each other again to limit the limiting block 6, thereby completing the installation of the top cover 2.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 utility model should be included within the protection scope of the present utility model.
