Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] See also Figures 1-10A PVC modifier mixing device for uniformly mixing comprises a mixer body (1), a mixing barrel (2) connected to the mixer body (1), a barrel cover (3) connected to the top of the mixing barrel (2), and a mixing blade (16) connected to the mixing barrel (2); an L-shaped ring plate (7) is overlapped on the top of the mixing barrel (2); a step groove (19) is provided in the L-shaped ring plate (7); an inner ring plate (9) is rotatably connected in the step groove (19); the inner ring plate (9) is L-shaped; two symmetrically arranged scrapers (10) are fixedly connected to the bottom of the inner ring plate (9); and the two scrapers (10) are both slidably connected to the inner wall of the mixing barrel (2).

[0021] The PVC modifier mixing device for uniform mixing of the present invention is configured such that when the inner wall of the mixing barrel 2 is adhered to the material, the inner ring plate 9 can be rotated to drive the two scrapers 10 at the bottom of the inner ring plate 9 to scrape the inner wall of the mixing barrel 2, thereby fully scraping off the adhered material and facilitating subsequent cleaning. The scrapers 10 can be taken out of the mixing barrel 2 from the L-shaped ring plate 7 along with the inner ring plate 9. This configuration makes subsequent cleaning more convenient.

[0022] As a preferred technical solution of the present invention, two scrapers (10) are fixedly connected to two stirring structures on one side close to the stirring blade (16), and the stirring structure includes a connecting rod (15), which is fixedly connected to the scraper (10), and the outer end of the connecting rod (15) is fixedly connected to the inclined plate (14), and the two groups of scrapers (10) are located above the stirring blade (16), and the scraper (10) is connected to a connecting piece for connecting the scraper (10) to the stirring blade (16).

[0023] Specifically, when the stirring blade 16 is rotating, the scraper 10 can be connected to the stirring blade 16 in advance through a connecting piece. In this way, when the stirring blade 16 rotates, it can drive the two sets of inclined plates 14 to rotate, which can improve the PVC mixing efficiency.

[0024] As a preferred technical solution of the present invention, the connecting member includes an extension plate (12), the outer end of the extension plate (12) is fixedly connected to a sleeve plate (13), and the sleeve plate (13) is clamped with the end of the stirring blade (16).

[0025] Specifically, when the scraper 10 needs to be connected to the stirring blade 16, the opening direction of the sleeve 13 at the end of the extension plate 12 can be located on the outside of the stirring blade 16, that is, when the stirring blade 16 rotates, its end will be stuck in the sleeve 13 and the extension plate 12. As the stirring blade 16 continues to rotate, the sleeve 13 will be pushed by the stirring blade 16 at any time, so that the scraper 10 can also rotate with the rotation of the stirring blade 16.

[0026] As a preferred technical solution of the present invention, an annular water trough (20) is provided in the L-shaped ring plate (7), a plurality of nozzles (8) are fixedly connected to the inner wall of the L-shaped ring plate (7), and the spraying direction of the plurality of nozzles (8) is close to the axis of the mixing barrel (2), and a water pipe (6) connected to the annular water trough (20) is fixedly connected to the outer wall of the L-shaped ring plate (7), and the water pipe (6) is externally connected to a water delivery device.

[0027] Specifically, in order to facilitate subsequent cleaning, cleaning water can be input into the water pipe 6 through an external water supply device, and the cleaning water enters the multiple nozzles 8 through the annular water tank 20, so that the nozzles 8 spray the cleaning water to clean the mixing barrel 2.

[0028] As a preferred technical solution of the present invention, the bottom surface of the inner ring plate (9) is connected to the bottom plate (17), the bottom of the bottom plate (17) is slidably connected to the bottom surface of the inner wall of the mixing barrel (2), the top of the bottom plate (17) is fixedly connected to the top of the bottom plate (17), an annular groove (18) is opened in the inner ring plate (9), the top of the top rod (32) passes through the annular groove (18) and is threadedly connected to a threaded ring (27) at one end, the top of the top rod (32) is threadedly connected to a first external rod (25), and the first external rod (25) is slidably connected to the annular groove (18).

[0029] Specifically, in the unloading stage, in order to make the bottom surface of the inner wall of the mixing barrel 2 unload more fully, the first external rod 25 can be threadedly connected to the top rod 32, and then the threaded ring 27 is rotated to loosen the threaded ring 27. At this time, the first external rod 25 can be lowered. After the first external rod 25 drives the bottom plate 17 to contact the bottom surface of the mixing barrel 2, the first external rod 25 is rotated. The first external rod 25 can rotate in the annular groove 18, or directly rotate the inner ring plate 9 to drive the first external rod 25 to rotate. This arrangement allows the bottom plate 17 to scrape all impurities adhering to the bottom surface of the inner wall of the mixing barrel 2 to the discharge port position, so that the material is fully unloaded and the amount of material residue is reduced.

[0030] As a preferred technical solution of the present invention, the inner wall of the inner ring plate (9) is fixedly connected to a cross bar (24), a slide groove (29) is provided in the cross bar (24), a transverse plate (23) is inserted and provided on the outer side of one end of the bottom plate (17) away from the top bar (32), a top block (28) is fixedly connected to the top of the transverse plate (23), the top block (28) passes through the slide groove (29) and is slidably connected to the slide groove (29), the top of the top block (28) is threadedly connected to a second external rod (26), and the second external rod (26) is inserted and slidably connected to the slide groove (29).

[0031] Specifically, in order to ensure that impurities on the bottom plate 17 are scraped off, the second external rod 26 can be threadedly connected to the top block 28, and then the second external rod 26 can be lowered. The second external rod 26 drives the top block 28 and the transverse plate 23 to descend at the same time. After descending, the transverse plate 23 can be directly engaged with the outer wall of the bottom plate 17. In this way, the second external rod 26 is pulled to move the second external rod 26 in the slide groove 29 of the cross bar 24, while driving the top block 28 and the transverse plate 23 at the bottom to move. In this way, the transverse plate 23 will fully push the material scraped by the bottom plate 17 to the discharge port, making the discharge more sufficient and reducing the amount of material residue again.

[0032] As a preferred technical solution of the present invention, a T-shaped plug rod (30) is inserted into the outer wall of the cross bar (24), one end of the T-shaped plug rod (30) passes through the cross bar (24) and is inserted into the top block (28), and the longitudinal plate of the T-shaped plug rod (30) is fixedly connected to two symmetrically arranged springs (31), and the other ends of the two springs (31) are fixedly connected to the outer wall of the cross bar (24).

[0033] Specifically, in order to ensure that the transverse plate 23 does not fall after the bottom plate 17 is lowered, the T-shaped rod 30 passes through the transverse bar 24 and is plugged into the top block 28 to ensure the stability of the transverse plate 23 on the transverse bar 24. When the transverse plate 23 needs to be lowered, it is only necessary to pull the T-shaped rod 30 to stretch the spring 31 so that the T-shaped rod 30 is separated from the top block 28.

[0034] Since the slide groove 29 is a rectangular groove, when the second external rod 26 descends, it can ensure that the transverse plate 23 is smoothly plugged into the bottom plate 17. At the same time, the first external rod 25 and the second external rod 26 are both external rod bodies. When in use, use them according to the above operation.

[0035] As a preferred technical solution of the present invention, mounting plates (4) are fixedly connected to both sides of the outer wall of the mixing barrel (2), and two threaded rods (5) are fixedly connected to the bottom surface of the L-shaped ring plate (7), and the threaded rods (5) pass through the outer side of one end of the mounting plate (4) and are threadedly connected to the nut.

[0036] Specifically, by connecting the threaded rod 5 to the mounting plate 4 through nuts, the stability of the L-shaped ring plate 7 on the mixing barrel 2 can be ensured.

[0037] As a preferred technical solution of the present invention, an embedding groove (21) is provided on the top surface of the inner ring plate (9), a handle (11) is rotatably connected in the embedding groove (21), and a groove (22) is provided on the bottom surface of the handle (11) away from the hinge end.

[0038] Specifically, when the inner ring plate 9 needs to be rotated, the handle 11 can be rotated from the embedded groove 21 through the groove 22, and then the handle 11 is held to rotate the inner ring plate 9, which makes it convenient to rotate the inner ring plate 9.
