[0002] Open mixing mill is the abbreviation of open rubber mixing mill, which is a rubber mixing machine with exposed rollers used to prepare plasticized rubber, mixed rubber or for hot mixing and molding.

[0003] The mixing mill has a simple structure, is relatively easy to manufacture, easy to operate, and convenient to maintain and disassemble. It is widely used in plastic product companies. However, when the device is actually used, after the material is placed on the working roll, it needs to be stretched by hand and moved to the working roll again. Then, before flipping and extruding, it needs to be manually trimmed and flipped continuously, resulting in huge physical exertion in manual operation. Even in the face of high temperatures, it is easy to cause damage to personal safety, which is not conducive to the safe and efficient use of the device.

[0004] Therefore, we provide an automatic rubber turning mechanism for a mixing mill. Utility Model Content

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] Embodiment 1: An automatic rubber turning mechanism for a mixing mill, such as Figure 1-Figure 4As shown, it includes a support plate 1 and at least two rotating rollers 2 rotatably arranged on one side of the support plate 1. There are at least two support plates 1, and the rotating roller 2 is located between the two support plates 1. A connecting rod 4 is slidably connected to one side of the support plate 1, and a telescopic motor 5 is arranged on one side of the connecting rod 4. An arc-shaped edge-collecting block 3 is fixedly connected to the side of the connecting rod 4 away from the telescopic motor 5. A rotating column 13 is rotatably arranged below the two arc-shaped edge-collecting blocks 3, and a plurality of limit rods 14 are fixedly connected to the outside of the rotating column 13. A guide plate 9 is slidably arranged below the rotating column 13, and a rotating belt 12 is arranged on the upper half of the guide plate 9. When the device is running, the two rotating rollers 2 are connected to the outer driving device under the support of the support plates 1 on both sides, so that the two rotating rollers 2 drive the placed materials to rotate. When the two rotating rollers 2 move the rotated and extruded materials downward, the curved surface of one side of the guide plate 9 is arranged below the two rotating rollers 2, so that the materials move along the inclined surface of the guide plate 9. The rotating belt 12 moves, and at the same time, the rotating effect of the rotating belt 12 makes the material move toward the rotating column 13. The rotating column 13 rotates in the opposite direction at the same time under the drive of the outer driving device, and the material contacts the rotating roller 2 under the limiting effect of the limiting rod 14. The material rotates upward due to the adsorption effect of the rotating roller 2 on the material, and then the two arc-shaped edge-collecting blocks 3 are telescopically moved under the support of multiple connecting rods 4 through the operation of the telescopic motors 5 on both sides, so as to achieve the edge-collecting processing of the material on the rotating roller 2, so that under the guiding support of the guide plate 9 and the rotating transportation of the rotating belt 12 and the limited reverse rotation of the limiting rod 14, the material can be automatically moved and turned during operation of the device, and the continuous edge-collecting and turning of the two arc-shaped edge-collecting blocks 3 can achieve the effect of efficient edge-collecting and turning of the material during rotation, thereby improving the automation efficiency of the device during operation and reducing manual operation steps.

[0026] like Figure 1-Figure 4 As shown, the arc-shaped edge-closing block 3 is fixedly connected to a connecting plate 6 via two connecting rods 4, the connecting plate 6 is fixedly connected to the output end of the telescopic motor 5, an auxiliary block 7 is provided on one side of the arc-shaped edge-closing block 3, the auxiliary block 7 is threadedly connected to a fastening bolt 8 and extends to its outside, the fastening bolt 8 is threadedly connected to the arc-shaped edge-closing block 3, and the stability of the arc-shaped edge-closing block 3 when it moves is ensured by simultaneously connecting the telescopic motor 5 and the two connecting rods 4 with the connecting plate 6, and the effect of simultaneously connecting and fastening the auxiliary block 7 and the arc-shaped edge-closing block 3 with the fastening bolt 8 is improved, thereby improving the applicability of the arc-shaped edge-closing block 3 when closing the edges of materials of different thicknesses, thereby improving the diversity of use of the device.

[0027] like Figure 1-Figure 4As shown, the rotating column 13 is rotatably connected to the support plate 1, and the guide plate 9 is located below the rotating roller 2. By connecting the rotating column 13 to the outer driving component separately, the rotation direction of the rotating column 13 can be adjusted separately to improve the stability of the device during operation, and by setting the guide plate 9 below the two rotating rollers 2 and by setting one side of the guide plate 9 as a curved structure, the accuracy of the material flow direction is ensured.

[0028] Embodiment 2: An automatic rubber turning mechanism for a mixing mill, such as Figure 1-Figure 4 As shown, the guide plate 9 is slidably connected to the support plate 1 through a sliding groove 15, and the sliding groove 15 is opened on the adjacent side of the two support plates 1. The sliding groove 15 opened on the two support plates 1 is used to limit and support the guide plate 9 when it slides, thereby ensuring the directional accuracy of the guide plate 9 when it moves, and by setting the connection method between the guide plate 9 and the sliding groove 15 to have a certain damping property, the stability of the guide plate 9 when it is running in a fixed position can be ensured.

[0029] like Figure 1-Figure 4 As shown, a rotating motor 10 is fixedly connected inside the guide plate 9, and a rotating cylinder 11 is fixedly connected to the output end of the rotating motor 10. There are at least two rotating cylinders 11 and the rotating cylinders 11 are rotatably connected to the guide plate 9. The two rotating cylinders 11 are connected to the rotating belt 12 by belt transmission. The rotating cylinders 11 are driven to rotate under the operation of the rotating motor 10, and the rotating belt 12 is connected to the two rotating cylinders 11. When the rotating motor 10 drives the rotating cylinder 11 on one side to rotate under the support of the guide plate 9, the rotating cylinder 11 on the other side is driven to rotate at the same time under the connection of the rotating belt 12 under the support of the guide plate 9, so that the rotating belt 12 can rotate smoothly and stably, thereby improving the efficiency of the rotating belt 12 in moving materials.

[0030] Working principle: by connecting the two rotating rollers 2 with the outer driving device under the support of the support plates 1 on both sides, the two rotating rollers 2 drive the placed materials to rotate. When the two rotating rollers 2 move the rotated and extruded materials downward, by setting the curved surface of one side of the guide plate 9 below the two rotating rollers 2, the material moves along the inclined surface of the guide plate 9 to the rotating belt 12. At the same time, the rotating belt 12 causes the material to move toward the rotating column 13. The rotating column 13 is driven by the outer driving device to rotate in the opposite direction at the same time. By the limiting effect of the limiting rod 14, the material is brought into contact with the rotating roller 2. The adsorption effect of the moving roller 2 on the material causes the material to rotate upward, and then the operation of the telescopic motors 5 on both sides causes the two arc-shaped edge-closing blocks 3 to telescope and move under the support of multiple connecting rods 4, so as to achieve the edge-closing processing of the material on the rotating roller 2. Under the guiding support of the guide plate 9, the rotating transportation of the rotating belt 12, and the limited reverse rotation of the limit rod 14, the material can be automatically moved and flipped during operation of the device, and the continuous edge-closing and flipping of the two arc-shaped edge-closing blocks 3 can achieve the effect of efficient edge-closing and flipping of the material during rotation, thereby improving the automation efficiency of the device during operation and reducing manual operation steps.

[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
