Description

Technical Field

[0001] This utility model relates to the field of plastic production technology, and in particular to a plastic granule pretreatment device for plastic production. Background Technology

[0002] In the field of plastic recycling and modification, material pretreatment is a crucial first step. Its core objective is to transform raw plastic particles of varying shapes, which may contain clumps, into fine powder with uniform particle size and consistent surface properties through crushing and grinding.

[0003] Most common plastic pellet pretreatment equipment on the market adopts a single-stage grinding structure, which crushes the material in one go through a set of fixed grinding discs. When processing larger or agglomerated hard plastics, the single-stage fine grinding discs directly bear huge impact and shear stress, which can easily lead to premature wear or damage of the grinding discs. It is difficult to accurately control the output particle size in one-time grinding. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies by proposing a plastic granule pretreatment equipment for plastic production, which results in a more concentrated particle size distribution and a more uniform surface of the finished powder, thus significantly improving product quality.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A plastic granule pretreatment device for plastic production includes a processing tank. A tank cover is provided on the front side of the processing tank, and an auxiliary assembly is provided on the side of the tank cover. An arc-shaped fixing plate is fixedly connected to the rear interior of the processing tank. A square fixing plate is fixedly connected to the rear interior of the processing tank at the end opposite to the arc-shaped fixing plate. A rotating shaft is provided on the upper side of the square fixing plate, and a rotating plate is rotatably connected to the outside of the rotating shaft. A movable shaft is rotatably connected to the middle rear of the processing tank. A preliminary grinding disc is fixedly connected to the outer wall of the movable shaft inside the processing tank. A transmission shaft is rotatably connected to the rear of the processing tank at the end opposite to the square fixing plate, and a fine grinding disc is fixedly connected to the outer wall of the transmission shaft.

[0007] Furthermore, support frames are fixedly connected to both the left and right sides of the outer wall of the processing tank, and a material inlet is provided at the upper end of the processing tank.

[0008] Furthermore, the auxiliary positioning assembly includes a rotating tube disk located inside the can lid and rotating thereon. A pusher plate is fixedly connected to the rear side of the rotating tube disk, and a first motor is fixedly connected to the middle of the outer side of the can lid. The middle of the rotating tube disk is fixedly connected to the drive end of the first motor.

[0009] Furthermore, an arc-shaped rail is provided at the upper front end of the can lid, and a discharge hole is provided at the lower end of the processing tank.

[0010] Furthermore, a rotating rod is fixedly connected to the center of the front side of the rotating plate, and the external part of the rotating rod is movably connected to the inside of the arc-shaped rail.

[0011] Furthermore, an auxiliary inclined plate is fixedly connected to the upper end of the square fixing plate.

[0012] Furthermore, a large gear is fixedly connected to the rear end of the movable shaft, a second motor is fixedly connected to the middle of the rear side of the processing tank, and the rear side of the movable shaft is fixedly connected to the drive end of the second motor.

[0013] Furthermore, a small gear is fixedly connected to the rear end of the drive shaft, and a third motor is fixedly connected to one end of the rear side of the processing tank. The rear side of the drive shaft is fixedly connected to the drive end of the third motor.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, by manually holding the rotating rod and sliding it inside the arc-shaped rail, the rotating plate is driven to rotate around the rotating axis and descend to the upper end of the arc-shaped fixed plate, forming a closed space. This effectively avoids cross-contamination. When only the preliminary grinding disc is used for coarse grinding, if it is in an open state, some coarse particles or impurities will inevitably enter the interior of the arc-shaped fixed plate, causing contamination. This can prevent large, hard materials from accidentally impacting the precision grinding disc, thus providing protection and increasing operational safety.

[0016] 2. In this utility model, by starting the second motor, the large gears meshing with each other rotate relative to each other. The preliminary grinding disc can quickly process larger or agglomerated plastic particles, reducing the burden of subsequent precision grinding and avoiding the clogging and efficiency bottleneck that may occur in single-stage fine grinding, thereby improving the overall processing speed. Particles that have been ground in one pass leak out from the discharge hole, and the remaining particles that need to be processed again are pushed into the fine grinding disc by the pushing force of the pusher plate. The finished powder has a more concentrated particle size distribution and a more uniform surface, which can significantly improve the quality of the product. Attached Figure Description

[0022] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figures 1-2 This utility model provides an embodiment of a plastic granule pretreatment device for plastic production, comprising a processing tank 1, a tank cover 3 on the front side of the processing tank 1, support frames 2 fixedly connected to the left and right sides of the outer wall of the processing tank 1, a feed inlet 8 at the upper end of the processing tank 1, a rotating tube disc 6 rotatably connected to the inner side of the tank cover 3, a pusher plate 7 fixedly connected to the rear side of the rotating tube disc 6, a first motor 5 fixedly connected to the middle of the outer side of the tank cover 3, and the middle of the rotating tube disc 6 fixedly connected to the drive end of the first motor 5. An arc-shaped rail 4 is provided on the upper front side of the can lid 3, and a discharge hole 14 is provided on the lower end of the processing tank body 1. A rotating rod 13 is fixedly connected to the middle front side of the rotating plate 12. The external part of the rotating rod 13 is movably connected to the inside of the arc-shaped rail 4. An arc-shaped fixing plate 9 is fixedly connected to the rear inside of the processing tank body 1. A square fixing plate 10 is fixedly connected to the rear end of the inner side of the processing tank body 1 at the opposite end of the arc-shaped fixing plate 9. A rotating shaft 11 is provided on the upper side of the square fixing plate 10. The rotating plate 12 is rotatably connected to the outside of the rotating shaft 11.

[0024] By manually holding the rotating rod 13 and sliding it along the arc of the arc-shaped rail 4, the rotating rod 13 drives the rotating plate 12 to rotate around the rotating shaft 11 and descend to the upper end of the arc-shaped fixed plate 9, forming a closed space. This effectively avoids cross-contamination. When only the preliminary grinding disc 19 is used for coarse grinding, if it is in an open state, some coarse particles or impurities will inevitably enter the interior of the arc-shaped fixed plate 9, causing contamination. This can prevent large, hard materials from accidentally hitting the precision fine grinding disc 23, thus providing protection and increasing operational safety. By starting the first motor 5, the rotating tube disc 6 is driven to rotate, and the rotating tube disc 6 drives the pusher plate 7 to rotate. Thus, the pusher plate 7 can push the material clockwise or counterclockwise for processing according to different situations.

[0025] Reference Figures 1-3 A movable shaft 16 is rotatably connected to the middle of the rear side of the processing tank 1. A preliminary grinding disc 19 is fixedly connected to the outer wall of the movable shaft 16 inside the processing tank 1. A transmission shaft 20 is rotatably connected to the opposite end of the square fixed plate 10 on the rear side of the processing tank 1. A fine grinding disc 23 is fixedly connected to the outer wall of the transmission shaft 20. An auxiliary inclined plate 15 is fixedly connected to the upper end of the square fixed plate 10. A large gear 18 is fixedly connected to the rear end of the movable shaft 16. A second motor 17 is fixedly connected to the middle of the rear side of the processing tank 1. The rear side of the movable shaft 16 is fixedly connected to the drive end of the second motor 17. A small gear 22 is fixedly connected to the rear end of the transmission shaft 20. A third motor 21 is fixedly connected to the opposite end of the rear side of the processing tank 1. The rear side of the transmission shaft 20 is fixedly connected to the drive end of the third motor 21.

[0026] The material to be processed is poured in through the feed port 8. The second motor 17 is started to drive the meshing large gears 18 to rotate relative to each other. The large gears 18 drive the primary grinding discs 19 to rotate, which can quickly process larger or clumped plastic particles, reduce the burden of subsequent precision grinding, and avoid the clogging and efficiency bottleneck that may occur in single-stage fine grinding, thereby improving the overall processing speed. The particles that have been ground in one pass leak out through the discharge port 14. The remaining particles that need to be processed again are pushed to the secondary grinding area by the pushing force of the pusher plate 7. The particles are more accurately conveyed to the middle of the two fine grinding discs 23 by the inclined surface of the auxiliary inclined plate 15 for secondary grinding. The finished powder has a more concentrated particle size distribution and a more uniform surface, which can significantly improve the quality of the product.

[0027] Working principle: The material to be processed is poured in through the feed inlet 8. The second motor 17 drives the meshing large gears 18 to rotate relative to each other. The large gears 18 drive the primary grinding discs 19 to rotate, which can quickly process larger or clumped plastic particles, reducing the burden on subsequent precision grinding and avoiding potential clogging and efficiency bottlenecks that may occur with single-stage fine grinding, thus improving the overall processing speed. Particles that have completed one grinding pass leak out through the discharge hole 14. The remaining particles requiring further processing are pushed to the secondary grinding area by the pusher plate 7. The inclined surface of the auxiliary inclined plate 15 more precisely conveys the particles to the middle of the two fine grinding discs 23 for secondary grinding. This results in a more concentrated particle size distribution and a more uniform surface in the finished powder, significantly improving product quality. By manually holding the rotating rod 13 and sliding it along the arc of the arc-shaped rail 4, the rotating rod 13 drives the rotating plate 12 to rotate around the rotating shaft 11 and descend to the upper end of the arc-shaped fixed plate 9, forming a closed space. This effectively avoids cross-contamination. When only the preliminary grinding disc 19 is used for coarse grinding, if it is in an open state, some coarse particles or impurities will inevitably enter the interior of the arc-shaped fixed plate 9, causing contamination. This can prevent large, hard materials from accidentally hitting the precision fine grinding disc 23, thus providing protection and increasing operational safety. By starting the first motor 5, the rotating tube disc 6 is driven to rotate, and the rotating tube disc 6 drives the pusher plate 7 to rotate. Thus, the pusher plate 7 can push the material clockwise or counterclockwise for processing according to different situations.
