Technical Field

[0001] The utility model relates to the technical field of plastic particle dust removal, in particular to a plastic particle dust removal device. Background Art

[0002] The dust removal device for plastic particles is a device used to remove the dust generated during the processing of plastic particles. During the processing of plastic particles, such as extrusion, injection molding or calendering, a large amount of dust is often generated and adheres to the surface of the plastic particles, which will affect the appearance quality of the product, making it appear unclean and rough, and may even leave defects or marks on the surface of the product, reducing the beauty of the product.

[0003] The traditional way to remove dust from plastic particles is to use air blowing to blow away the dust adhering to the surface of the plastic particles. However, the direction of the air blowing is generally fixed, making it difficult to blow the air evenly on the surfaces of multiple plastic particles, resulting in uneven dust removal of the plastic particles. Therefore, it is necessary to design a dust removal device for plastic particles to solve the above problem. Utility Model Content

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, many specific details are elaborated in the following description to facilitate a full understanding of the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments of the following public specification.

[0021] See also Figure 1-5 The utility model provides a dust removal device for plastic particles, including a shell 1 with a columnar structure, the upper and lower sides of the shell 1 are respectively connected with an air inlet pipe 2 and a dust exhaust pipe 3, one side of the shell 1 is provided with an opening, and a placement cage 4 for storing plastic particles is inserted therein, the shell 1 is provided with a rotating mechanism for driving the placement cage 4 to rotate, and one side of the shell 1 is provided with a cover plate 5 for blocking its opening. Through such a design, the air inlet pipe 2 can blow air into the shell 1, so that the air can sweep the plastic particles in the placement cage 4, and blow the dust adhered to the surface of the plastic particles into the dust exhaust pipe 3, and at the same time, the rotating mechanism will drive the placement cage 4 to rotate continuously in the shell 1, so that the plastic particles will also be continuously flipped in the placement cage 4, so that the air can be blown on each plastic particle more evenly, so as to achieve the effect of uniform dust removal.

[0022] In order to enable the placement cage 4 to rotate, in some embodiments, it is proposed that the rotating mechanism includes a circular plate 6 which is arranged on one side of the inner wall of the outer shell 1 and can rotate itself. Two symmetrical long rods 7 are fixedly connected to one side of the circular plate 6. The two long rods 7 have grooves 8 on the opposite sides along their length directions. Positioning protrusions 9 are formed on both sides of the surface of the placement cage 4 and are inserted into the corresponding grooves 8. When the circular plate 6 rotates, the two long rods 7 will rotate along the axial direction of the circular plate 6, and can drive the placement cage 4 to rotate synchronously, so that the plastic particles can continuously roll in the placement cage 4. When the placement cage 4 needs to be taken out, the placement cage 4 can also be directly pulled out from the two long rods 7.

[0023] Specifically, a servo motor 10 with an output shaft facing upward is fixedly installed on one side of the housing 1, and a bevel gear 11 is fixedly connected to the end of the output shaft of the servo motor 10. A rotating shaft inserted into one side of the housing 1 through a bearing is fixedly connected to one side of the circular plate 16, and a circular plate 2 12 is fixedly connected to the side of the rotating shaft outside the housing 1. An end face gear 13 meshing with the bevel gear 11 is fixedly connected to the surface of the circular plate 2 12. When the output shaft of the servo motor 10 rotates, the bevel gear 11 is driven to rotate, and the end face gear 13 can drive the synchronous rotation of the circular plate 2 12 through tooth matching, and achieve the purpose of driving the circular plate 6 itself to rotate.

[0024] See also Figure 5The specific connection method between the cover plate 5 and the shell 1 is as follows: the cover plate 5 is hinged on one side of the shell 1, and a lock 15 for fixing the position of the cover plate 5 is installed on the shell 1, so that the cover plate 5 can block the opening of the shell 1, and the cover plate 5 can be opened by opening the lock 15, so as to facilitate the removal of the placement cage 4 from the shell 1.

[0025] It should be noted that one side of the cover plate 5 located inside the shell 1 is fixedly connected to a mounting seat 16, and a movable ball 17 is movably inserted into the mounting seat 16. The surface of the movable ball 17 abuts against one side of the placement cage 4, so that after the cover plate 5 is closed, the movable ball 17 can press the placement cage 4 between it and the circular plate 6 to avoid the placement cage 4 from deviating left and right when rotating. Such a design will be more reasonable.

[0026] See also Figure 3 A notch is provided on one side of the placement cage 4, and a sealing plate 41 is inserted into the notch through threaded engagement. After the sealing plate 41 is unscrewed, the dust-removed plastic particles can be taken out of the placement cage 4.

[0027] Furthermore, a dust collecting box 18 is connected to the bottom of the dust exhaust pipe 3, and a collecting box 19 with an open top is inserted into one side of the dust collecting box 18, so that the dust blown out by the air can be accumulated inside the collecting box 19, and the collected dust can be cleaned by pulling the collecting box 19 out from one side of the dust collecting box 18.

[0028] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, the technical solution of the present invention can be subjected to a variety of simple modifications, and these simple modifications all belong to the protection scope of the present invention.
