Technical Field
[0001] This utility model relates to the field of plastic granule processing technology, specifically to a high-efficiency plastic granule mixing device. Background Technology
[0002] In the production of plastic products, the mixing of plastic granules is a crucial step. By scientifically and rationally mixing different types, colors, and properties of plastic granules, diverse characteristics can be imparted to plastic products, meeting the performance requirements of various products ranging from everyday consumer goods to industrial components. For example, by mixing high-strength plastic granules with flame-retardant plastic granules, robust and fire-resistant plastic products can be produced, widely used in electronic device housings, building materials, and other fields. Uniformly mixed plastic granules ensure stable quality and consistent performance of plastic products during subsequent processing and molding, effectively reducing product defects and improving the product qualification rate.
[0003] For example, Chinese utility model patent application number 202221682345.6 discloses a mixing hopper for processing plastic granules. By setting up a feeding screen, larger impurities in the plastic granules can be initially screened. Then, under the action of an electromagnet, a conical disc adsorbs metallic impurities from the plastic granules, and a suction pipe sucks up lighter dust and plastic granule fragments, ensuring the plastic granules are clean and free of impurities. However, this device still has certain shortcomings.
[0004] Stirring plastic granules using only a single stirring shaft results in low mixing efficiency and quality, leading to a longer mixing time and a significant extension of the entire production cycle.
[0005] Therefore, we propose a high-efficiency plastic pellet mixing device to solve the problems mentioned above. Utility Model Content

[0034] Please see Figures 1-7This utility model provides a technical solution: a high-efficiency plastic granule mixing device, including a support frame 1, a support 2, a mixing box 3, a discharge pipe 4, a connecting frame 5, a first servo motor 6, a main gear 7, a movable plate 8, a first bearing component 9, a stirring assembly 10, a secondary gear 11, a conveying frame 12, a mounting frame 13, a second servo motor 14, a transmission shaft 15, a conveying auger 16, a first bevel gear 17, a second bearing component 18, a connecting shaft 19, a second bevel gear 20, a cam 21, a feeding frame 22, a baffle plate 23, a through hole 24, a guide bar 25, an arc-shaped block 26, a baffle 27, a telescopic spring 28, and a guide telescopic rod 29.

For internal maintenance, the maintenance door on the front surface of the connecting frame 5 can be opened. First bearing components 9 are installed on both sides of the movable plate 8. The stirring assembly 10 is located inside the first bearing component 9 and is rotatably connected to it. The main gear 7 and the auxiliary gear 11 mesh with each other. Rotation of the movable plate 8 drives the auxiliary gear 11 to rotate along the edge of the main gear 7. The main gear 7 drives the auxiliary gear 11 to rotate, which in turn drives the stirring assembly 10 to rotate. The movable plate 8 drives the stirring assembly 10 to revolve, thus enabling the stirring assembly 10 to more efficiently mix the plastic particles in the mixing tank 3. The main gear 7 is installed inside the connecting frame 5 via a fixing block. The main gear 7 is located on both sides of the connecting plate 8. A secondary gear 11 is provided on both sides, and a stirring assembly 10 is installed below each secondary gear 11. The conveying frame 12 is connected to the interior of the mixing box 3. A mounting frame 13 is installed on the left side of the conveying frame 12, and a second servo motor 14 is installed on the left side of the mounting frame 13. A transmission shaft 15 is installed on the right side of the second servo motor 14 through the output shaft. The transmission shaft 15 is connected to the conveying auger 16.

Under the action of the conveying auger 16, the plastic granules are pushed along the conveying frame 12 towards the mixing box 3 to avoid the accumulation of plastic granules.
[0035] A conveying auger 16 is installed inside the conveying frame 12. A first bevel gear 17 is installed on the drive shaft 15. A connecting shaft 19 is installed above the mounting bracket 13 via a second bearing 18, and a second bevel gear 20 is installed below the connecting shaft 19. The second bevel gear 20 and the first bevel gear 17 are perpendicular to each other and mesh with each other. A cam 21 is installed above the connecting shaft 19. When the plastic particles move to the baffle plate 23, the plastic particles will pass through the through hole 24 and enter the mixing box 3 under the dispersion action of the guide bar 25. At the same time, the first bevel gear 17 on the drive shaft 15 rotates with the drive shaft 15, and the first bevel gear 17 drives the second bevel gear 20 to rotate. The second bevel gear 20 drives the connecting shaft 19 to rotate, and the cam 21 above the connecting shaft 19 rotates accordingly. A baffle plate 23 is provided inside the conveying frame 12, and a through hole 24 is opened on the baffle plate 23. A guide bar 2 is installed in the middle of the through hole 24. 5. Arc-shaped blocks 26 and baffles 27 are respectively installed on the left and right sides of the baffle plate 23. The baffles 27 are connected to the feed frame 22 by a telescopic spring 28. The cam 21 is located on the left side of the arc-shaped block 26. The arc-shaped block 26 is connected to the feed frame 22 by a guide telescopic rod 29. The baffle plate 23 is slidably connected to the feed frame 22. The range of left and right movement of the through hole 24 on the baffle plate 23 does not exceed the inner wall of the feed frame 22. During the rotation of the cam 21, the arc-shaped block 26 will be intermittently squeezed. Under the action of the squeezing of the cam 21 and the rebound force of the telescopic spring 28, the arc-shaped block 26 drives the baffle plate 23 to slide left and right in the feed frame 22. The left and right sliding of the baffle plate 23 changes the position of the guide strip 25. Then, through the moving guide strip 25, the plastic particles added to the mixing box 3 are dispersed, further preventing the plastic particles from clumping together and affecting the mixing effect. The guide telescopic rod 29 guides the left and right movement of the arc-shaped block 26.
[0036] Working principle: When using this high-efficiency plastic granule mixing equipment, firstly, the plastic granules are poured into the feed frame 22, and the second servo motor 14 is started. When the plastic granules move to the baffle plate 23, they will pass through the through hole 24 and enter the mixing box 3 under the dispersion action of the guide bar 25. At the same time, the first bevel gear 17 on the drive shaft 15 rotates with the drive shaft 15, and the first bevel gear 17 drives the second bevel gear 20 to rotate. The second bevel gear 20 drives the connecting shaft 19 to rotate, and the cam 21 above the connecting shaft 19 rotates accordingly. During the rotation of the cam 21, it will intermittently compress the arc shape. Under the compression of cam 21 and the rebound force of extension spring 28, block 26 drives baffle 23 to slide left and right in feed frame 22. The left and right sliding of baffle 23 changes the position of guide strip 25, thereby dispersing the plastic particles added to mixing box 3 through the moving guide strip 25, preventing the plastic particles from clumping together and affecting the mixing effect. At the same time, second servo motor 14 drives transmission shaft 15 to rotate, and transmission shaft 15 drives conveyor auger 16 to rotate. Under the action of conveyor auger 16, plastic particles are pushed along conveyor frame 12 towards mixing box 3 to avoid accumulation of plastic particles.
[0037] When the plastic granules enter the mixing chamber 3, the first servo motor 6 is activated. The output shaft of the first servo motor 6 drives the movable plate 8 to rotate. The rotation of the movable plate 8 drives the secondary gear 11 to rotate along the edge of the main gear 7. The main gear 7 drives the secondary gear 11 to rotate, which in turn drives the stirring assembly 10 to rotate. The movable plate 8 drives the stirring assembly 10 to revolve, thereby enabling the stirring assembly 10 to more efficiently stir and mix the plastic granules in the mixing chamber 3. After mixing is complete, the control valve on the discharge pipe 4 is opened, and the mixed plastic granules are discharged through the discharge pipe 4. This completes a series of operations.
