Description

Technical Field

[0001] This utility model relates to the field of recycled plastic pellet production technology, and in particular to a recycled plastic pellet screening mechanism. Background Technology

[0002] Recycled plastics are produced by extruding recycled or waste plastics using a screw extruder, and then cutting them into pellets using a pelletizer. Recycled plastic pellets have a wide range of applications. They can be used to manufacture various plastic bags, buckets, basins, toys, furniture, stationery, and other household items and plastic products.

[0003] When screening recycled plastic granules, the raw materials are usually filtered through the screen inside the screening machine. However, because the recycled plastic granules contain plastic particles with a particle size similar to the size of the screen mesh, these particles are prone to clogging the mesh. Over time, this leads to more clogging and affects the screening effect. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the prior art that plastic particles with a mesh size similar to the screen mesh can easily clog the mesh and affect the screening effect. The invention provides a recycled plastic particle screening mechanism that uses a material turning component and a brush plate to move closely to the screen surface to brush out the plastic particles stuck in the screen mesh, thereby preventing mesh clogging and ensuring the screening efficiency of the screen.

[0005] To achieve the above objectives, this utility model provides a recycled plastic pellet screening mechanism, including a screening box, a screen inside the screening box, a discharge pipe on one side of the screening box, a discharge hopper below the screen, a turning assembly inside the screening box, the turning assembly mounted on a drive shaft, a brush plate and a first dispersing rod mounted on the turning assembly, a feeding cylinder on one side of the screening box, and a feeding hopper on the feeding cylinder;

[0006] The material turning assembly includes an installation cylinder, which is sleeved on the drive shaft. Multiple material turning plates are circumferentially installed on the installation cylinder. The side of the material turning plate near the screen is connected to a brush plate, and the other side of the material turning plate is connected to multiple first material dispersing rods.

[0007] As a further description of the above technical solution: the flipping plate is detachably connected to the brush plate by bolts, and the flipping plate has a plurality of screw holes that are compatible with the bolts.

[0008] As a further description of the above technical solution: a feeding auger is provided inside the feeding cylinder, and the feeding auger is sleeved on the drive shaft.

[0009] As a further description of the above technical solution: one end of the drive shaft is connected to the drive wheel, and the drive wheel is connected to the drive motor through a drive belt.

[0010] As a further description of the above technical solution: the inside of the feeding hopper is connected to a material distribution shaft via a bearing seat, and multiple second material distribution rods are connected to the material distribution shaft.

[0011] As a further description of the above technical solution: a first transmission wheel is provided on the drive shaft, and a second transmission wheel is provided on the bulk material shaft, and the first transmission wheel and the second transmission wheel are connected by a transmission belt.

[0012] As a further description of the above technical solution: the screening box is provided with an inspection cover.

[0013] The above technical solution has the following advantages or beneficial effects:

[0014] This invention uses a screen inside a screening box to screen recycled plastic particles entering the screening box. A drive shaft can rotate a turning assembly, which in turn moves a brush plate close to the screen surface, brushing out plastic particles stuck in the screen mesh, preventing clogging, ensuring screening efficiency, and maintaining the continuity of the screening process. During rotation, the first dispersing rod can agitate and disperse the plastic particles in the screening box, making the particles more evenly distributed on the screen and improving the screening effect. At the same time, multiple turning plates and the first dispersing rod can break up the cohesive plastic particles, improving the screening effect. Attached Figure Description

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0023] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0024] like Figure 1-4 As shown, the recycled plastic pellet screening mechanism of this utility model includes a screening box 1, a screen 2 inside the screening box 1, a discharge pipe 3 on one side of the screening box 1, a discharge hopper 4 below the screen 2, a turning assembly 5 inside the screening box 1, the turning assembly 5 being mounted on a drive shaft 6, a brush plate 7 and a first material dispersing rod 8 mounted on the turning assembly 5, a feeding cylinder 9 on one side of the screening box 1, and a feeding hopper 10 mounted on the feeding cylinder 9; the turning assembly 5 includes an installation cylinder 51, which is sleeved on the drive shaft 6, and multiple turning plates 52 are circumferentially mounted on the installation cylinder 51, the side of the turning plate 52 near the screen 2 being connected to the brush plate 7, and the other side of the turning plate 52 being connected to multiple first material dispersing rods 8.

[0025] In the technical solution of this utility model, the recycled plastic particles entering the screening box 1 are screened by the screen 2 inside the screening box 1. The drive shaft 6 can drive the turning component 5 to rotate. The rotation of the turning component 5 drives the brush plate 7 to move closely against the surface of the screen 2, brushing out the plastic particles stuck in the mesh of the screen 2, preventing the mesh from clogging, ensuring the screening efficiency of the screen 2, and maintaining the continuity of the screening process. During the rotation, the first dispersing rod 8 can move and disperse the plastic particles in the screening box 1, so that the particles are more evenly distributed on the screen, improving the screening effect. At the same time, the multiple turning plates 52 and the first dispersing rod 8 can break up the plastic particles, improving the screening effect.

[0026] like Figure 2 and Figure 4 As shown, the flip plate 52 is detachably connected to the brush plate 7 by bolts 11. The flip plate 52 has multiple screw holes 12 that are compatible with the bolts 11. The bolts 11 facilitate the installation and removal of the brush plate 7, and make it easy to inspect and replace the brush plate 7.

[0027] like Figure 1 and Figure 2 As shown, a feeding auger 13 is installed inside the feeding cylinder 9 and is mounted on the drive shaft 6. The feeding auger 13 can stably transport materials into the screening box 1 and can also break up the cohesive materials.

[0028] One end of the drive shaft 6 is connected to the drive wheel 14, and the drive wheel 14 is connected to the drive motor 15 through the drive belt. The drive motor 15 drives the drive shaft 6 to rotate through the drive wheel 14, providing power to components such as the material turning assembly 5 and the feeding auger 13, ensuring that all components of the screening mechanism operate in coordination.

[0029] like Figure 1 and Figure 2 As shown, a material dispersing shaft 17 is connected to the inside of the feeding hopper 10 via a bearing seat 16. Multiple second material dispersing rods 18 are connected to the material dispersing shaft 17. The material dispersing shaft 17 drives the second material dispersing rods 18 to rotate, which can stir the material inside the feeding hopper 10, prevent the material inside the feeding hopper 10 from clogging, and allow the material to enter the feeding cylinder 9 smoothly. At the same time, the rotation of the second material dispersing rods 18 driven by the material dispersing shaft 17 can initially disperse the recycled plastic particles in the feeding hopper 10 before the particles enter the feeding cylinder 9, preventing the particles from clumping together and entering the screening box 1, thus creating conditions for uniform distribution and efficient screening on the screen 2.

[0030] The drive shaft 6 is equipped with a first transmission wheel 19, and the bulk material shaft 17 is equipped with a second transmission wheel 20. The first transmission wheel 19 and the second transmission wheel 20 are connected by a transmission belt 21. The transmission belt 21 is linked with the drive shaft 6, and the power of the drive shaft 6 drives the bulk material shaft 17 to rotate. The bulk material shaft 17 and the second bulk material rod 18 can be driven to rotate without the need for a separate drive device, so as to realize the rational distribution and utilization of power, simplify the equipment structure, and improve the overall operating efficiency.

[0031] like Figure 1 and Figure 2 As shown, the screening box 1 is equipped with an inspection cover 22; by opening the inspection cover 22, operators can easily check the blockage of the screen 2, the wear of the material turning component 5, etc., and clean the screen 2 and replace worn parts in a timely manner to ensure that the screening mechanism always maintains a good working condition.

[0032] Working principle: By pouring recycled plastic granules into the feeding hopper 10, the drive motor 15 starts, and the power is transmitted to the drive shaft 6 via the drive belt. The drive shaft 6 drives the dispersing shaft 17 to rotate via the transmission belt 21. The second dispersing rod 18 initially disperses the granules in the feeding hopper 10. Then, the feeding auger 13 evenly conveys the granules to the screen 2 in the screening box 1. The screen 2 screens the granules, and smaller granules fall through the screen 2 and are discharged into the discharge hopper 4. At the same time, the drive shaft 6 drives the turning assembly 5 to rotate, and the brush plate 7 cleans the screen 2 to prevent clogging. The first dispersing rod 8 agitates the granules on the screen to distribute them evenly and improve the screening effect.

[0033] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
