[0002] Medical-grade plastic particles are granular compounds made primarily of high-molecular-weight polymers or synthetic resins, with added plasticizers, stabilizers, and other additives. These particles typically have unique designations such as grade numbers, clearly defined application ranges, specific molecular weight ranges, and melt flow indices. Common medical-grade plastic particles include polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET), and polycarbonate (PC). During the processing of medical-grade plastic particles, a stirring device is required to ensure uniform mixing of the plastic particles and additives.

[0026] 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.

[0027] In the embodiments, by Figure 1-4 The present invention discloses a stirring device for processing medical plastic particles. The present invention includes a base 1, a support plate 2 fixedly connected to the top of the base 1, a rotating device 3 provided on the outside of the support plate 2, a fixed sleeve 4 fixedly connected to the outside of the rotating device 3 and rotatably connected to the support plate 2, a stirring box 5 fixedly connected to the inside of the fixed sleeve 4 by fasteners, a fixed frame 6 fixedly connected to the inside of the stirring box 5, a stirring device 7 rotatably connected to the fixed frame 6 inside the stirring box 5, a feeding trough opened inside the stirring box 5, a second electric push rod 8 fixedly connected to the outside of the stirring box 5, an electric feeder 9 fixedly connected to the outside of the second electric push rod 8, and a discharge pipe 10 fixedly connected to the bottom of the electric feeder 9, which penetrates and extends into the feeding trough.

[0028] The mixing tank 5 is wider at the top and narrower at the bottom, and the fixing frame 6 is inclined downwards.

[0029] In this embodiment, during actual use, this structural design allows plastic particles to naturally slide down the inner wall of the mixing tank 5 to the bottom during stirring, reducing residue on the inner wall of the mixing tank 5 and thus reducing cleaning dead zones. Simultaneously, the inclined arrangement of the fixing frame 6 better supports the stirring device 7, ensuring the stability of the stirring process.

[0030] The stirring device 7 includes a motor 71 fixedly connected to the outside of the stirring box 5, a stirring shaft 72 fixedly connected to the outside of the output shaft of the motor 71 and rotatably connected to the fixed frame 6, and a plurality of stirring rods 73 fixedly connected to the outside of the stirring shaft 72.

[0031] In this embodiment, during actual use, after the motor 71 starts, it drives the stirring shaft 72 to rotate through the output shaft, and the stirring shaft 72 then drives the stirring rod 73 to rotate, thereby realizing the stirring and mixing of plastic particles in the mixing box 5, ensuring that the plastic particles and additives can be fully mixed.

[0032] The stirring shaft 72 extends through and to the bottom of the fixed frame 6. The stirring frame 11 located below the fixed frame 6 is fixedly connected to the outside of the stirring shaft 72, and the stirring frame 11 is attached to the inner wall of the mixing box 5.

[0033] In this embodiment, during actual use, the stirring shaft 72 drives the stirring frame 11 to rotate during the stirring process. The stirring frame 11 is in close contact with the inner wall of the stirring box 5, which can effectively scrape off the plastic particles on the inner wall, reduce cleaning dead corners, and further improve the stirring effect.

[0034] The rotating device 3 includes a first electric push rod 31 fixedly connected to the outside of the support plate 2, a rack 32 fixedly connected to the outside of the first electric push rod 31, a rotating shaft 33 fixedly connected to the fixed sleeve 4 inside the support plate 2, and a gear 34 meshing with the rack 32 fixedly on the outside of the rotating shaft 33.

[0035] In this embodiment, during actual use, when the first electric push rod 31 extends and retracts, it drives the rack 32 to move along the slide groove. The rack 32 meshes with the gear 34, causing the rotating shaft 33 to rotate, thereby driving the fixed sleeve 4 and the mixing box 5 to rotate and tilt back and forth at a certain angle, further reducing cleaning dead angles and improving the mixing effect.

[0036] The support plate 2 has a groove inside, and the rack 32 has a slider 12 that is slidably connected to the groove on the outside.

[0037] In this embodiment, during actual use, the slider 12 slides in the groove, which can effectively limit the movement direction of the rack 32, allowing it to move smoothly under the drive of the first electric push rod 31, thereby ensuring the reliability and stability of the rotating device 3.

[0038] Working principle:

[0039] In practical use, plastic particles and additives are first added to the mixing tank 5 through the feeding trough. The motor 71 is started, and its output shaft drives the stirring shaft 72 to rotate. The stirring shaft 72 then drives the stirring rod 73 and the stirring frame 11 to rotate, achieving mixing of the plastic particles. Simultaneously, the first electric push rod 31 extends and retracts, driving the rack 32 to move along the slide. The rack 32 meshes with the gear 34, causing the rotating shaft 33 to rotate, thereby driving the fixed sleeve 4 and the mixing tank 5 to rotate and tilt back and forth at a certain angle, further reducing cleaning dead zones and improving the mixing effect. During the mixing process, the second electric push rod 8 can push the electric feeder 9 to move as needed. The electric feeder 9 discharges its internal additives through an electrically operated valve, and the additives are placed into different positions within the mixing tank 5 through the discharge pipe 10, accelerating the mixing efficiency of the additives and plastic particles. After mixing is complete, the discharge port at the bottom of the mixing tank 5 is opened to discharge the mixed plastic particles. During operation, it is necessary to ensure that all components are securely connected and to regularly inspect and maintain the equipment to ensure the normal operation of the mixing device.
