[0020] The present utility model provides a solid rubber mill, the structure of which is as Figures 1 to 3As shown in the figure, it includes a workbench 1. At the top of the workbench 1, a first side plate 2 and a second side plate 3 are fixed. Between the first side plate 2 and the second side plate 3, a first extrusion wheel 4 and a second extrusion wheel 5 are movably connected. And outside the second side plate 2, a first driving motor 20 is installed. The output end of the first driving motor 20 passes through the second side plate 2 and is connected to one end of the first extrusion wheel 4. The other ends of the first extrusion wheel 4 and the second extrusion wheel 5 both pass through the first side plate 2 and are both connected with first gears 21 that mesh and drive each other. Inside the first side plate 2 and the second side plate 3, a first connecting plate 8 and a second connecting plate 9 are respectively provided; on the sides of the first side plate 2 and the second side plate 3, a first arc-shaped notch 6 and a second arc-shaped notch 7 are respectively opened. And outside the second side plate 3, a telescopic cylinder 17 is fixed through a connecting seat 16 and a rotating shaft 14 is movably connected. The outer sides of the first connecting plate 8 and the second connecting plate 9 are respectively movably connected with a first sliding rod 10 and a second sliding rod 11. The inner sides are respectively fixed with bearings 22 and a second driving motor 12. The first sliding rod 10 and the second sliding rod 11 are respectively slidably connected with the first arc-shaped notch 6 and the second arc-shaped notch 7. And the other end of the second sliding rod 11 is fixed with a rotating rod 13. The other end of the rotating rod 13 is fixedly connected with the rotating shaft 14. The other end of the rotating shaft 14 is fixed with a second gear 15. The telescopic rod of the telescopic cylinder 17 is connected with a moving rod 18. On the side of the moving rod 18 close to the second gear 15, a plurality of racks 19 that mesh and drive with it are fixed. The output end of the second driving motor 12 is connected with a screw rod 23. A moving block 24 is threadedly connected to the screw rod 23 and its other end is connected with the bearing 22. A cutting mechanism is installed on the side of the moving block 24. By driving the moving rod 18 to move through the piston rod of the telescopic cylinder 17, the plurality of racks 19 are engaged with the second gear 15 to drive. At this time, the rotating shaft 14 drives the rotating rod 13 to rotate the cutting mechanism for angle adjustment. Using a solid rubber kneader, the cutting angle of the cutting mechanism can be flexibly adjusted, which is convenient for enterprises to operate and use.

[0021] Specifically, the cutting mechanism includes a first hydraulic cylinder 25. The first hydraulic cylinder 25 is fixed on the side of the moving block 24. Its piston rod is connected with a cutter 26. By driving the cutter 26 to move inward through the piston rod of the first hydraulic cylinder 25, the rubber is cut off.

[0022] Furthermore, a second hydraulic cylinder 27 is fixed outside the second side plate 3. Between the first extrusion wheel 4 and the second extrusion wheel 5, there is a scraper 28. At the top of the scraper 28, a mounting block 29 is fixed. The piston rod of the second hydraulic cylinder 27 passes through the second side plate 3 and is connected with the mounting block 29. By driving the scraper 28 to move through the piston rod of the second hydraulic cylinder 27, the rubber material adhered to the first extrusion wheel 4 and the second extrusion wheel 5 is scraped off, avoiding affecting subsequent production.

[0023] Furthermore, a material trough opening 30 is opened at the top of the workbench 1. A material box 31 is installed at the bottom. The material box 31 is located directly below the material trough opening 30. And on both sides of its top, fixing blocks 32 are fixed. The fixing blocks 32 and the workbench 1 are connected by screws 33, which are used to collect rubber products.

[0024] Further, two guide rods 34 are fixed between the first connecting plate 8 and the second connecting plate 9. Guide blocks 35 are fixed to both the top end and the bottom end of the moving block 24. The guide blocks 35 are slidably connected to the guide rods 34 to prevent the moving block 24 from rotating when moving.

[0025] Further, a limit block 36 is fixed to the other end of the first sliding rod 10 to prevent the first sliding rod 10 from disconnecting from the first arc-shaped notch 6.

[0026] The working principle of the present utility model is as follows: First, start the telescopic cylinder 17. Its piston rod drives the moving rod 18 to move, causing several racks 19 to mesh and drive with the second gear 15. At this time, the rotating shaft 14 drives the rotating rod 13, which in turn drives the cutter 26 to rotate to a suitable position. Then, start the first hydraulic cylinder 25 and the second driving motor 12. The piston rod of the first hydraulic cylinder 25 drives the cutter 26 to move inward to contact the rubber, and the output end of the second driving motor 12 drives the screw rod 23 to rotate, causing the cutter to move horizontally for cutting.

[0027] The above description is only a description of the preferred embodiments of the present utility model and does not limit the scope of the present utility model in any way. Any changes and modifications made by those of ordinary skill in the field of the present utility model based on the above disclosure fall within the protection scope of the claims.
