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.

[0021] Example 1

[0022] As attached Figures 1 to 4The plastic granule mixer shown includes a mixing drum 1, a feeding box 2 fixedly welded to the top of the mixing drum 1, a first connecting frame 3 rotatably connected inside the feeding box 2, a filter screen 4 disposed on the first connecting frame 3, a second connecting frame 5 rotatably connected inside the feeding box 2 and below the first connecting frame 3, the second connecting frame 5 also disposed on the filter screen 4, and a rotating shaft 9 fixedly connected to both sides of the first connecting frame 3 and the second connecting frame 5, one rotating shaft 9 rotating through the side wall of the feeding box 2 and connected to a gear 10. Two sets of limiting seats 16 are provided on the side wall. Each set of limiting seats 16 is rotatably connected to a threaded rod 15. One end of the threaded rod 15 is connected to an adjusting knob 17. A slider 14 is threadedly sleeved on the outside of the threaded rod 15. A rack 11 is connected to the upper surface of the slider 14 through a connecting plate 13. The rack 11 is meshed with a gear 10. Two guide seats 12 are fixedly welded to the side wall of the feeding box 2. Limiting grooves are opened on the surface of the two guide seats 12. The two connecting plates 13 slide through the limiting grooves opened on the surface of the guide seats 12 respectively.

[0023] In operation, the device can be adjusted by rotating the adjusting screw rod 15 via the adjusting knob 17. The rotating screw rod 15 drives the slider 14 to move the rack 11 via the connecting plate 13. The moving rack 11 meshes with the gear 10, thereby driving the gear 10, the rotating shaft 9, and the first connecting frame 3 and the second connecting frame 5 connected to the rotating shaft 9 to rotate and adjust. At the same time, the tilt angle of the two filter screens 4 can be adjusted. By adjusting the tilt angle of the two filter screens 4, the speed of the plastic particles can be controlled, helping to slowly feed the plastic particles and avoid feeding too quickly, which would affect the mixing effect of the plastic particles. At the same time, the setting of two sets of filter screens 4 can screen the input materials and screen out agglomerated plastic particles, preventing some sticky plastic particles from entering the mixing drum 1 and affecting the uniform mixing effect of the device.

[0024] Example 2

[0025] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 4 As shown below, see details:

[0026] In a preferred embodiment, an elastic connecting cloth 6 is fixedly connected between one side of the first connecting frame 3 and the inner wall of the feeding box 2, and an elastic connecting cloth 6 is fixedly connected between both sides of the second connecting frame 5 and the inner wall of the feeding box 2. The elastic connecting cloth 6 here is existing technology, such as DuPont Lycra fabric, nylon fabric, etc., so it will not be described in detail here. A discharge port 7 is opened on the side wall of the feeding box 2 and on one side of the second connecting frame 5, and a discharge nozzle 8 is welded on the outer surface of the feeding box 2 and at the discharge port 7. Furthermore, when the device is in use, the plastic particles that have been screened by the two sets of filters 4 will be discharged into the feeding box 2 through the discharge port 7 and the discharge nozzle 8, and then uniformly collected and processed. The setting of the elastic connecting cloth 6 can prevent some clumps of plastic particles from falling into the mixing drum 1 through the gap between the edge of the filter 4 and the feeding box 2, which would affect the screening effect of the two sets of filters 4 on the plastic particles.

[0027] In a preferred embodiment, four support legs 18 are evenly spaced on the outer wall of the mixing drum 1. Each of the four support legs 18 has a fixed base 19 at its bottom end, and an anti-slip rubber pad is fixedly connected to the bottom end of each base 19. A stirring rod 20 is rotatably connected inside the mixing drum 1. Two sets of connecting rods 22 are fixedly arranged on the outer side of the stirring rod 20. Two scrapers 21 are symmetrically fixedly connected to the stirring rod 20 via the two sets of connecting rods 22. A secondary stirring blade 24 is fixedly connected to the surface of each scraper 21 facing the stirring rod 20. Two sets of main stirring blades 23 are symmetrically arranged vertically on the outer side of the stirring rod 20. The bottom wall of the mixing drum 1 is located near the stirring rod 20. A discharge pipe 25 is provided on one side of the mixing drum 1, and a motor is bolted to the bottom of the outside of the mixing drum 1. The output end of the motor is connected to one end of the mixing rod 20 through a coupling. A valve is provided on the discharge pipe 25. Furthermore, when the device is in use, the motor can drive the mixing rod 20, the connecting rod 22, and the main mixing blade 23 to rotate. The rotating connecting rod 22 drives the scraper 21 and the auxiliary mixing blade 24 provided on the scraper 21 to rotate, thereby mixing the plastic particles in the mixing drum 1. At the same time, the two rotating scrapers 21 scrape off the plastic particles adhering to the inner wall of the mixing drum 1.

[0028] The working process of this utility model is as follows: First, the raw materials are screened at the feeding box 2 and then fed into the mixing drum 1. Then, the stirring rod 20, the connecting rod 22, and the main stirring blade 23 are driven by the motor to rotate. The rotating connecting rod 22 drives the scraper 21 and the auxiliary stirring blade 24 set on the scraper 21 to rotate, thereby mixing the plastic particles in the mixing drum 1. At the same time, the two rotating scrapers 21 scrape off the plastic particles adhering to the inner wall of the mixing drum 1. The mixed plastic particles are discharged through the discharge pipe 25 and then proceed to the next processing step.

[0029] When it is necessary to screen the plastic granules fed into the mixing drum 1, the adjusting screw rod 15 can be rotated by adjusting knob 17. The rotating screw rod 15 drives the slider 14 to move the rack 11 through the connecting plate 13. The moving rack 11 meshes with the gear 10, thereby driving the gear 10, the rotating shaft 9, and the first connecting frame 3 and the second connecting frame 5 connected to the rotating shaft 9 to rotate and adjust. At the same time, the tilt angle of the two filter screens 4 can be adjusted. By adjusting the tilt angle of the two filter screens 4, the speed of the plastic granules can be controlled, which helps to feed the plastic granules slowly and evenly, avoiding feeding too quickly and affecting the mixing effect of the device on the plastic granules. At the same time, the setting of two sets of filter screens 4 can screen the input material and screen the agglomerated plastic granules, avoiding some sticky plastic granules from entering the mixing drum 1 and affecting the uniform mixing effect of the device. The above is the working principle of this plastic granule mixer that is conducive to uniform mixing.
