[0002] The mill is an open type rubber mixing mill, which is used for the processing of plasticating, mixing, heat mixing and sheet pressing of rubber or plastic and other polymer materials. When the traditional mill is used for mixing and processing of rubber or plastic, the rubber turning is usually completed by manual operation, so that the materials are mixed with the ingredients. One common operation method is "three-angle wrapping", that is, the operator manually turns the rubber surface on the rotating roller, wraps it into a triangular shape, and then puts it into the compression roller of the mill. The manual turning method is greatly affected by the skill of the operator, and cannot guarantee the consistency of material mixing. Multiple times of material turning by manual operation are difficult to standardize, and manual operation is not only laborious, but also has high safety hazards.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0034] Example 1

[0035] Please see the appendix Figures 1 to 5 As shown in the figure, a hydraulic automatic rubber-turning mechanism for a two-roll mill in this embodiment of the present invention includes two mounting bases 1. During installation, the mounting bases 1 are fixed to the mill base and located above the mill's rollers. The mechanism also includes:

[0036] The main turning shaft 2 is located above the front of the two mounting seats 1 and can rotate actively; the secondary turning shaft 3 is located above the rear of the two mounting seats 1 and can rotate with the main turning shaft 2. In use, the turned material is put between the main turning shaft 2 and the secondary turning shaft 3, and the material and the agent are mixed evenly by the roller pressure of the main and secondary shafts.

[0037] The reciprocating material turning assembly 5 is located below the turning main shaft 2 and includes a hydraulic cylinder 51 and a guide rod 56. The guide rod 56 is fixed between two mounting seats 1 and its outer end is slidably sleeved with a sliding sleeve 53. Two rollers 54 are detachably connected to the outer side of the sliding sleeve 53. A connecting seat 52 is fixed to the rear side of the sliding sleeve 53. The hydraulic cylinder 51 is fixed to the outer side of a mounting seat 1 and its extended end is fixedly connected to the connecting seat 52.

[0038] In operation, the material is fed through two rollers 54 and then between the main turning shaft 2 and the auxiliary turning shaft 3. The extruded material returns to the rollers of the open mill. During the rolling and mixing process, the reciprocating extension and retraction of the hydraulic cylinder 51 drives the mounting base 1 to move back and forth, thereby causing the two rollers 54 to reciprocate and flip the material on both sides, participating in the mixing process and achieving the purpose of uniform mixing of materials and reagents. There is no need for manual "triangle-wrapping" turning; during operation, only manual feeding of material into the upper roller 54 is required. Workers do not need to frequently contact materials and equipment, making the operation easy and safe.

[0039] The roller 54 includes a mounting shaft 541. A sleeve 542 is rotatably connected to the outer end of the mounting shaft 541 via a bearing. Both the upper and lower ends of the mounting shaft 541 are threaded. An end cap 543 is fitted onto the upper end of the mounting shaft 541, and the lower end is fitted into a sliding sleeve 53. The sleeve 542 is made of stainless steel with a smooth surface and is rotatable with low resistance, allowing for smooth material passage. Furthermore, both the roller 54 as a whole and the sleeve 542 are detachable, facilitating subsequent maintenance and replacement, and demonstrating strong practicality.

[0040] Furthermore, the outer surface of the sleeve 542 is set as a concave arc shape. The arc shape can guide the edges and corners of the material to be bent and rolled, thereby improving the mixing uniformity.

[0041] Furthermore, the reciprocating material turning assembly 5 also includes a second guide rod 57, which is fixed between the two mounting seats 1 and has a second sliding sleeve 55 slidably sleeved on its outer side. The second sliding sleeve 55 is fixedly connected to the connecting seat 52. By setting the second sliding sleeve 55 and the second guide rod 57, the mounting seats 1 can be further guided and constrained to ensure the stability of the movement of the mounting seats 1, thereby ensuring the stability of the movement of the two rollers 54.

[0042] Furthermore, guide rollers 4 are rotatably connected to the lower front end of the two mounting bases 1. The guide rollers 4 facilitate the smooth feeding of the flipped material into the flipping main shaft 2 and the flipping secondary shaft 3.

[0043] Example 2

[0044] Please see Figure 1 and Figure 2As shown, based on Embodiment 1, the material turning spindle 2 includes a main material turning roller 21 that is rotatably connected to the mounting base 1 via two bearing seats 23. The main material turning roller 21 is driven by a motor reducer assembly 22.

[0045] The material turning sub-shaft 3 includes two cantilever 32s that are rotatably connected to the mounting base 1 via bearing seat 2 31. A secondary material turning roller 33 is rotatably connected between the two cantilever 32 and is pressed against the main material turning roller 21 at an angle above it.

[0046] When in use, start the motor reducer assembly 22 to drive the main turning roller 21 to rotate. The two ends of the auxiliary turning roller 33 are set with rough surfaces. When the main turning roller 21 rotates, it will drive the auxiliary turning roller 33 to rotate together, thereby squeezing the incoming material and realizing the mixing function.

[0047] A crossbeam 6 is fixed between the two mounting bases 1 and the rear side between the two cantilever arms 32. A guide plate 7 is fixedly connected to the opposite side of the two crossbeams 6. The upper guide plate 7 is inclined towards the auxiliary turning roller 33, and the lower guide plate 7 is inclined towards the main turning roller 21. Folded edges are provided on both the left and right sides of the guide plate 7 to constrain the material. After the material passes through the main and auxiliary turning rollers 33, it is guided by the two guide plates 7 and then returns to the rollers of the open mill.

[0048] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
