Description

Technical Field

[0001] This utility model relates to the technical field of rubber production, and in particular to a rubber mixing open mill. Background Technology

[0002] During rubber production and processing, the thickness of the extruded rubber sheet needs to be adjusted using an open mill. Existing open mills primarily use two rollers to clamp the extruded rubber, and the thickness of the rubber sheet is controlled by the distance between the two rollers. For example, patent application CN202222364551.9 discloses a novel rubber mixing open mill. This patent places the rubber to be processed between two outer rollers 11. Two motors 16 drive two second rotating shafts 15 to rotate, which in turn drives two first rotating shafts 9 to rotate the two outer rollers 11, thus processing and mixing the rubber. Heating or cooling liquid is injected into the liquid inlet pipe 19, and flows through the water inlet pipe 12 from the second opening 13 and the third opening 14 into the inner roller 10 and outer roller 11. Within the first cavity 25, the outer roller 11 is heated or cooled, thereby heating or cooling the rubber and improving the efficiency of rubber mixing. The heating or cooling liquid flows out from the outlet pipe 20 through the second opening 13 on the side away from the third opening 14 and through the second cavity 26. The electric telescopic rod 21 drives the baffle 22 to move, thereby limiting the width of the processed rubber and preventing the rubber from falling off the edge of the outer roller 11. Rotating the two rotating handles 24 causes the two discs 23 to drive the two double-axis threaded screws 4 to rotate, thereby moving the four sliding seats 5, driving the four rotating seats 6 to move, causing the first rotating shaft 9, the second rotating shaft 15 and the outer roller 11 to move, thereby changing the distance between the two outer rollers 11, thereby changing the thickness of the produced rubber.

[0003] The existing patent makes it inconvenient to clean the rubber adhering to the rollers during use, and the direction of the rubber sheet moving downward after molding is not easy to adjust. Therefore, this application proposes a more flexible rubber mixing open mill. Utility Model Content

Detailed Implementation

[0025] The embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0026] like Figure 1-3 In this first embodiment, a rubber mixing open mill includes...

[0027] Base plate 10;

[0028] Two support plates 20 are arranged parallel to each other on the base plate 10, and each support plate 20 has a lifting hole 31 that passes through the support plate 20.

[0029] Two lifting plates 30 are respectively installed in two lifting holes 31, and each lifting plate 30 has a moving hole 52 that passes through the lifting plate 30.

[0030] The drive roller 60 is rotatably positioned between the two lifting plates 30;

[0031] Two first movable plates 51 are respectively movably disposed in two movable holes 52;

[0032] The driven roller 50 is rotatably disposed between the two first moving plates 51;

[0033] The second movable plate 62 is movably mounted on the base plate 10, and the moving direction of the second movable plate 62 is the same as the moving direction of the first movable plate 51.

[0034] Two positioning plates 61 are mounted on the second movable plate 62;

[0035] The guide roller 60 is rotatably positioned between the two positioning plates 61.

[0036] This embodiment is implemented as follows:

[0037] In use, the first moving plate 51 moves the driven roller 50, changing the distance between it and the drive roller 40, thus adjusting the rubber thickness. The second moving plate 62 moves the guide roller 60 directly below the drive roller 40 and the driven roller 50. As the formed rubber sheet moves downward, it comes into contact with the guide roller 60. The direction of rotation of the guide roller 60 then moves the formed rubber sheet to one side, allowing for more flexible rubber sheet production. When the rubber is thick, the lifting plate 30 can move upward to increase the distance between the drive roller 40 and the guide roller 60, facilitating the turning of thicker rubber sheets.

[0038] The lifting plate 30 in this application is provided with a first reducer 41 that drives the drive roller 40 to rotate, and the first reducer 41 has a first drive motor 42 that drives the first reducer 41.

[0039] The positioning plate 61 in this application is provided with a second reducer 66 for driving the guide roller 60, and the second reducer 66 has a second drive motor 67 for driving the second reducer 66.

[0041] The present application uses a movable cylinder 54 to drive the connecting plate 53 to move, and the connecting plate 53 drives the first movable plate 51 to move within the movable hole 52.

[0042] Please see Figure 1 , 2 The lifting plate 30 has two sliding grooves 32 at its two ends, and the two sliding grooves 32 respectively slide and clamp the inner sidewall of the lifting hole 31.

[0043] The sliding groove 32 provided in this application enables the lifting plate 30 to slide more stably within the lifting hole 31.

[0044] Please see Figure 1 , 2 A lifting cylinder 33 is provided on the support plate 20, and the output end of the lifting cylinder 33 is connected to the lifting plate 30.
