Description

Technical Field

[0001] This utility model relates to the field of plastic recycling technology, and in particular to a plastic pellet recycling and sorting device. Background Technology

[0002] Plastics are materials made of high molecular polymers, characterized by their lightweight, durability, and high plasticity. They are widely used in daily life and industrial fields, such as packaging, containers, electronic products, and building materials. There are many types of plastics, including polyethylene, polypropylene, and polyvinyl chloride, each with its unique properties and uses. Although plastics bring convenience to human life, their non-degradability also causes environmental problems. Therefore, the sustainable use and recycling of plastics are receiving increasing attention. Plastic particles need to be sorted during recycling. Plastic particle sorting devices are specialized equipment used to screen, grade, and remove impurities from plastic particles. They use different technologies, such as screening, magnetic separation, and photoelectric separation, to separate mixed plastic particles according to their material, color, shape, or particle size to meet different process and production needs. Current plastic particle size sorting devices typically involve pouring plastic particles into a sorting box and then screening them through layers of screens inside the box. However, these screens are usually fixed inside the sorting box, making it difficult to disassemble and remove the plastic particles when they become clogged. Furthermore, it's not convenient to replace screens with different aperture sizes to meet different needs, which negatively impacts subsequent plastic particle screening. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figures 1-4 A plastic pellet recycling and sorting device includes a collection bin 1, a horizontal plate 2 at the top of the collection bin 1, a motor 3 connected to the top of the horizontal plate 2, a rotating rod 4 connected to the bottom of the motor 3, a connecting plate 5 at the bottom of the rotating rod 4, a mounting plate 6 at the bottom of the connecting plate 5, a support rod 7 connected to the bottom of the mounting plate 6, a sleeve 8 fitted onto the surface of the support rod 7, a first sorting bin 9 connected to the bottom of the sleeve 8, and a second sorting bin 10 connected to the bottom of the first sorting bin 9; an annular plate 11 movably fitted onto the surface of the support rod 7, a rack 12 connected to the inner wall of the annular plate 11, a gear 13 connected to the surface of the rack 12, and a threaded rod 14 threadedly connected to the connecting plate 5 and the mounting plate 6. Through the operation of the motor 3, the rotating rod 4 can drive the connecting plate 5, the mounting plate 6, and the support rod 7. The rod 7, sleeve 8, first sorting barrel 9, and second sorting barrel 10 rotate to facilitate the sorting of plastic particles through the first sorting barrel 9 and the second sorting barrel 10. The bottom of the collection barrel 1 is provided with a discharge chute, and the bottom cross section of the collection barrel 1 is inverted conical, which facilitates the discharge of the screened plastic particles through the discharge chute. When it is necessary to replace the sorting barrel, the annular plate 11 can be rotated to move the rack 12 on the surface of the gear 13, which can drive the threaded rod 14 to rotate. Since the threaded rod 14 is threadedly connected to the connecting plate 5 and the mounting plate 6, the threaded rod 14 can be turned out from the inside of the connecting plate 5, so that the sorting barrel can be removed from the bottom of the connecting plate 5 for replacement. The sleeve 8 is connected to the sorting barrel by a detachable connection method such as bolts.

[0027] Furthermore, the inner bottom end of the annular plate 11 is provided with a first sliding groove 15, and the inner side of the first sliding groove 15 is slidably connected to a first slider 16 which is rotatably connected to the bottom end of the threaded rod 14. This facilitates the movement of the annular plate 11 at the bottom end of the threaded rod 14 through the first sliding groove 15 and the first slider 16.

[0028] Furthermore, baffles 17 are respectively attached to the top two sides of the collection bucket 1, and the top of the baffles 17 is connected to a connecting pipe 18, which is connected to a vacuum cleaner to collect the dust raised inside the collection bucket 1. An air inlet is provided on the rear side of the collection bucket 1.

[0029] Furthermore, the inner walls of the sleeve 8 are symmetrically provided with second sliding grooves 19, and the interior of the second sliding grooves 19 is slidably connected to a second slider 20 connected to the support rod 7. This facilitates the movement of the sleeve 8 through the second sliding grooves 19 onto the surface of the second slider 20, allowing the sleeve 8 and the sorting barrel at its bottom to be moved upwards, thus cleaning the plastic particles clogging inside the sorting barrel.

[0030] Furthermore, the support rod 7 has grooves 21 on both sides, and a spring 22 is connected inside the grooves 21. A fixing rod 23 is connected to one side of the spring 22. Multiple fixing holes 24 connected to the fixing rod 23 are equidistantly opened on both sides of the sleeve 8. This is so that after the sleeve 8 moves the sorting barrel to the designated position, the fixing rod 23 connected to it can be moved into the fixing hole 24 by the action of the spring 22, so that the position of the sleeve 8 and the sorting barrel can be fixed.

[0031] Furthermore, a stop 25 is connected to the opening of the groove 21 to block the fixing rod 23. The stop 25 is designed to block the fixing rod 23, which has a "T" shaped cross section, and prevent the fixing rod 23 from being squeezed out of the groove 21 by the spring 22.

[0032] 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.
