Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of chlorinated polyethylene raw material crushing, and specifically, to a chlorinated polyethylene raw material crushing device. Background Art
[0002] Chlorinated polyethylene is a saturated polymer material with excellent weather resistance, ozone resistance, chemical resistance and aging resistance. When producing chlorinated polyethylene products, it is necessary to crush polyethylene materials.
[0003] After retrieval, the utility model patent with the publication number of CN220638571U discloses a polyethylene raw material crushing, filtering and screening device, which includes a bottom plate. The bottom ends of the four sides of the bottom plate are fixedly installed with bases, the top end of the bottom plate is fixedly installed with a screening box, the top end of the screening box is fixedly installed with a crushing box, a feeding port is arranged at the top end of the crushing box, two crushing rollers are rotatably installed inside the crushing box, and a driving structure is arranged on one side of the screening box. By setting the crushing rollers, crushing blocks, driving structure and guiding structure, the integration of crushing and screening can be effectively realized, and the utilization rate of the driving motor is improved. The staff pours polyethylene raw materials into the crushing box from the feeding port, starts the driving motor, the output end of the driving motor drives the rotating rod to rotate, the pulley one on the rotating rod drives the pulley two to rotate through a belt, and the pulley two drives the crushing rollers to rotate. Since the main gear and the secondary gear are meshed, the two crushing rollers start to rotate in opposite directions, and the crushing blocks on the crushing rollers can crush the polyethylene raw materials.
[0004] However, the above patent still has the following deficiencies: only one set of crushing rollers is used to crush the materials, which is likely to result in poor crushing effect. There will be more raw materials remaining in the screening frame and they need to be manually put into the crushing box for re-crushing, affecting the crushing efficiency; and it is not convenient to automatically put the materials to be crushed into the crushing box. When a large amount of raw materials are poured into the crushing box manually at one time, it is easy to cause blockage, which also affects the crushing effect, and pouring raw materials manually slowly wastes labor. Therefore, we propose a chlorinated polyethylene raw material crushing device. Summary of the Utility Model

[0032] Specifically, please refer toFigure 3 , on both sides of the upper screening plate 8 and the lower screening plate 10, they are respectively in contact with the inner wall of the screening box 2.
[0033] In this embodiment, it is to prevent the chlorinated polyethylene raw materials on the upper screening plate 8 and the connecting rod 9 from falling from the side.

[0037] In this embodiment, the control panel 22 is used to control the third motor 21, the first motor 14, the second motor 15, and the electric push rod 7.
[0038] Specifically, please refer to Figure 4 , the side surface of the spiral feeding rod 20 is in contact with the inner wall of the lifting cylinder 17.
[0039] In this embodiment, it is to ensure that the rotation of the spiral feeding rod 20 can smoothly drive the chlorinated polyethylene raw materials to move upward.
[0040] Working principle: When in use, first start the first motor 14 to drive an upper crushing roller 4 to rotate clockwise, and start the second motor 15 to drive a lower crushing roller 5 to rotate clockwise. The transmission between the two first gears 12 is used to make the two upper crushing rollers 4 rotate inwardly towards each other, and the transmission between the two second gears 13 is used to make the two lower crushing rollers 5 rotate inwardly towards each other. At the same time, start the electric push rod 7 to drive the upper screening plate 8, the connecting rod 9 and the lower screening plate 10 to reciprocate up and down. Then start the third motor 21 to drive the spiral feeding rod 20 to rotate, put the chlorinated polyethylene raw material to be crushed into the inner cavity of the loading hopper 19. The chlorinated polyethylene raw material in the inner cavity of the loading hopper 19 falls to the bottom of the inner cavity of the lifting cylinder 17. The spiral feeding rod 20 rotating in the inner cavity of the lifting cylinder 17 drives the chlorinated polyethylene raw material to move upward. When the chlorinated polyethylene raw material moves to the top of the inner cavity of the lifting cylinder 17, it is discharged from the injection pipe 18, so that the chlorinated polyethylene raw material falls from the feed port 16 into the inner cavity of the screening box 2. Then, the two rotating upper crushing rollers 4 are used to initially crush the chlorinated polyethylene raw material, and the crushed material falls onto the upper screening plate 8. The material that meets the screening conditions falls into the inner receiving box 23, and the material that does not meet the conditions falls from the bottom end of the upper screening plate 8 between the two lower crushing rollers 5. The two lower crushing rollers 5 are used to crush the material again. At this time, the crushed material falls onto the lower screening plate 10. The material that meets the screening conditions falls into the inner receiving box 23, and the material that does not meet the conditions falls from the bottom end of the lower screening plate 10 into the outer receiving box 24 for collection. Finally, pour the material in the outer receiving box 24 into the loading hopper 19 for re-crushing, and that's it.
[0041] As described above, it is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improved concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
