Description

Technical Field

[0001] This utility model relates to the field of plastic processing technology, specifically to a plastic particle stirring device. Background Technology

[0002] A plastic particle mixing device is a piece of equipment used to mix plastic granules. It primarily uses rotating mixing blades to evenly mix the granules. Its working principle involves the rapid rotation of a screw, which lifts the material from the bottom center of the container to the top, then disperses it in an umbrella-like pattern back to the bottom. This causes the material to tumble and mix within the container, allowing for the uniform mixing of large quantities of material in a short time.

[0003] The plastic particle mixing device uses the rapid rotation of a screw to lift the material from the bottom center of the barrel to the top, then scatters it in an umbrella-like shape and returns to the bottom. This up-and-down tumbling mixing method ensures that the material is evenly mixed in a short time.

[0004] Existing plastic particle mixing devices have the following shortcomings:

[0005] When mixing plastic particles, various raw materials tend to accumulate at the bottom inner side of the mixing tank. The stirring rod rotates in a circular motion during mixing, which fails to fully mix the various raw materials located at the bottom inner side of the mixing tank, thus reducing the mixing efficiency.

[0006] Existing mixing devices adjust the mixing speed by regulating the output power of the motor. However, frequently switching the motor's output power can reduce the motor's lifespan and increase mixing costs. Furthermore, mixing different types of materials at the same speed cannot meet current mixing requirements. Utility Model Content

[0034] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0035] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual images. They should not be construed as limiting the scope of this patent. To better illustrate the embodiments of the present invention, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product.

[0036] Reference Figures 1 to 8 As shown, a plastic particle mixing device includes a base plate 1 and a support plate 2, with the support plate 2 fixedly mounted on the top of the base plate 1. It also includes a controller, a mixing mechanism, and a speed-changing mechanism.

[0037] The transmission mechanism is fixedly installed at the bottom of the support plate 2. The transmission mechanism includes a first gear 3, a second gear 4, a third gear 5, a fourth gear 6, an adjustment component, and a lifting component. The first gear 3 is rotatably installed at the top of the base plate 1. A connecting plate 7 is fixedly installed on the outer wall of the support plate 2. The second gear 4 is rotatably installed at the bottom of the connecting plate 7, and the third gear 5 is meshed with the first gear 3. A rotating rod 8 is fixedly installed at the top of the base plate 1. The third gear 5 and the fourth gear 6 are both fixedly installed on the outer wall of the rotating rod 8, and the fourth gear 6 is meshed with the second gear 4.

[0038] The stirring mechanism is fixedly mounted on the outer wall of the support plate 2. The stirring mechanism includes a stirring tank 9, a driving assembly, a stirring component, and two support plates 10. Each support plate 10 is fixedly mounted on the outer wall of the support plate 2. The stirring tank 9 is inserted into the support plate 10. The driving assembly is located on the top of the fixing ring 23. The stirring component is located on the driving assembly. The stirring tank 9 is rotatably connected to the support plate 10 and fixedly connected to the top of the rotating rod 8. The adjusting assembly, the lifting assembly, and the driving assembly are all electrically connected to the controller.

[0039] Reference Figures 1 to 8As shown, the adjustment assembly includes a stepper motor 11, an adjusting gear 12, a rack 13, and a guide rail 14. The guide rail 14 is fixedly mounted on the top of the base plate 1 via a support frame. The rack 13 is slidably mounted on the guide rail 14. The stepper motor 11 is fixedly mounted on the top of the base plate 1. The adjusting gear 12 is fixedly mounted on its output end, and the adjusting gear 12 is meshed with the rack 13. The stepper motor 11 is electrically connected to the controller. When it is necessary to stir multiple plastic particles, in order to reduce the stirring time, the stepper motor 11 is manually started by the controller. Since the adjusting gear 12 is fixedly connected to the output end of the first motor, and the rack 13 is meshed with the adjusting gear 12, and the guide rail 14 is fixedly connected to the base plate 1, and the rack 13 is slidably connected to the guide rail 14, the stepper motor 11 drives the rack 13 to rise vertically along the direction of the guide rail 14.

[0040] Reference Figures 1 to 8 As shown, the lifting assembly includes a mounting plate 15, a dual-axis motor 16, and two transmission gears 17. Connecting plates are fixedly mounted on the top of the first gear 3 and the bottom of the second gear 4, and each connecting plate has a slot 18 for meshing with the two transmission gears 17. The mounting plate 15 is fixedly mounted on the rack 13, and the dual-axis motor 16 is fixedly mounted on the mounting plate 15.

The bottom of each of the two gears 4 is fixedly designed with a connecting plate, and each connecting plate is designed with a slot 18 that meshes with two transmission gears 17. This allows one of the transmission gears 17, which is away from the bottom plate 1, to enter the slot 18 in the connecting plate at the bottom of the second gear 4, thus achieving the meshing connection between the transmission gear 17 and the slot 18. In addition, the second gear 4 meshes with the fourth gear 6. The diameter of the second gear 4 is smaller than the diameter of the fourth gear 6, thereby achieving the deceleration of the mixing tank 9. When the stepper motor 11 drives the rack 13 to descend vertically along the guide rail 14, since the first gear 3 meshes with the third gear 5, and the diameter of the first gear 3 is larger than the diameter of the third gear 5, the mixing tank 9 increases speed. Therefore, this mixing device can flexibly adjust the mixing speed according to the type of plastic particles, thereby improving the flexibility and practicality of this mixing device and meeting different mixing needs.

[0041] Reference Figures 1 to 8As shown, the drive assembly includes a drive motor 19, a support block 20, a connecting frame 21, and two bevel gears 22.

The drive motor 19 is fixedly provided on the support block 20. One bevel gear 22 is fixedly provided on the output end of the drive motor 19. The connecting frame 21 is fixedly provided on the fixing ring 23. The other bevel gear 22 is rotatably provided on the connecting frame 21, and the two bevel gears 22 are meshed. The drive motor 19 is electrically connected to the controller. When multiple plastic particles enter the mixing tank 9 together, the worker starts the drive motor 19 through the controller. Since one bevel gear 22 is fixedly connected to the output end of the drive motor 19, and the other bevel gear 22 is fixedly connected to the connecting shaft 26, and the connecting shaft 26 is rotatably connected to the connecting frame 21, the two bevel gears 22 mesh, thereby driving the connecting shaft 26 to rotate.

[0042] Reference Figures 1 to 8 As shown, the stirring assembly includes a rotating shaft 24, a traction block 25, a connecting shaft 26, a connecting block 27, a rotating ring 28, and a stirring part.

In addition, the rotating shaft 24 is fixedly connected to the traction block 25, thereby driving the traction block 25 to rotate. Since the rotating ring 28 is rotatably connected to the connecting frame 21, the traction block 25 is hinged to the rotating ring 28. In addition, the stirring part is fixedly connected to the traction block 25 through the stirring shaft. The stirring part is inclinedly designed inside the stirring tank 9, so that the traction block 25 drives the stirring part to rotate in a conical shape inside the stirring tank 9, thereby achieving full stirring of plastic particles and reducing stirring dead corners.

[0043] Reference Figures 1 to 8 As shown, a material distribution bin 29 is fixedly provided on the outer wall of the support plate 2, and the material distribution bin 29 is located above the mixing tank 9. Several detachable material distribution boxes 30 are inserted inside the material distribution bin 29, and each material distribution box 30 has a discharge port at the bottom. Each discharge port is equipped with a baffle 31. Before the plastic particles are mixed, the workers put different plastic particles into the material distribution boxes 30 respectively, and determine the ratio of different plastic particles according to different volumes. Then the workers remove the baffle 31, and the plastic particles before mixing fall into the mixing tank 9 through the discharge port.

[0044] Reference Figures 1 to 8As shown, several stirring plates 32 are fixedly arranged at equal intervals on the stirring part. Each stirring plate 32 is provided with a stirring groove 33. When the stirring part rotates in a conical shape in the stirring tank 9, the several stirring plates 32 and the stirring groove 33 can make the plastic particles more fully stirred, reduce the stirring time, and improve the stirring effect and stirring efficiency.

[0045] Reference Figures 1 to 8 As shown, the guide rail 14 is provided with a clearance groove 34 for the mounting plate 15 to be raised and lowered, so that when the mounting plate 15 is raised and lowered by the rack 13, the clearance groove 34 provides clearance space for the mounting plate 15, thus achieving the clearance effect.

[0046] Reference Figures 1 to 8 As shown, the bottom of the mixing tank 9 is provided with a discharge plate 35, and a handle is fixed on the outer wall of the discharge plate 35.
