Description

Technical Field

[0001] The utility model relates to the technical field of rubber processing, in particular to an open mill for processing rubber sealing rings. Background Art

[0002] Rubber refers to a highly elastic polymer material with reversible deformation. Rubber is elastic at room temperature and can produce large deformation under very small external force. It can return to its original shape after the external force is removed. The mixing mill is a machine that heats and molds rubber compounds between two rollers rotating in opposite directions. The mixing mill uses the shearing and extrusion effect of the rollers on the rubber compound to reduce its elasticity and increase its plasticity, making it easier to make rubber sealing rings.

[0003] For example, the utility model with authorization announcement number CN217226241U discloses an open mill for producing ED rings. By starting the cylinder to drive the connecting shaft to move, the cleaning plate can be driven to move in the discharge chute to clean up the waste accumulated in the discharge chute. By pulling the pull rod to both sides to drive the movable rod to disengage from the plug-in block, the cleaning plate can be pulled out, making it convenient to replace the cleaning plate.

[0004] This prior art also has the following problems when used:

[0005] When the distance between the roller of the device and the inner bottom surface of the discharge chute is large, it is inconvenient to add rubber to the top of the roller. When the distance between the roller and the inner bottom surface of the discharge chute is small, the roller easily blocks the movement of the cleaning plate on the inner bottom surface of the discharge chute. When the device replaces the cleaning plate, after the operator pulls the pull rod to both sides, the operator needs to hold the pull rod with both hands to maintain the position of the pull rod. At this time, it is difficult for the operator to remove and install the cleaning plate independently, and the assistance of other operators is required. Utility Model Content

[0027] like Figure 1-Figure 4As shown, a lifting assembly is arranged inside the U-shaped base 1, and the lifting assembly consists of a first lifting plate 2, a first servo motor 3, a second servo motor 4, a rotating shaft 5, a second lifting plate 7, a T-shaped slider 8, a connecting plate 9, a fixing plate 11, an electric telescopic rod 12, an installation box 13, a fixing rod 16 and a first connecting rod 17. A symmetrical first lifting plate 2 and a second lifting plate 7 are slidably connected inside the U-shaped base 1, and a T-shaped slider 8 is fixedly arranged on one side of the first lifting plate 2 and the second lifting plate 7 away from each other. A T-shaped slide groove adapted to the T-shaped slider 8 is arranged inside the U-shaped base 1, and the T-shaped slider 8 slides with the U-shaped base 1 through the T-shaped slide groove. The first lifting plate 2 and the second lifting plate 7 are connected dynamically, and the T-shaped slider 8 cooperates with the T-shaped slide groove to guide and limit the movement of the first lifting plate 2 and the second lifting plate 7. The first lifting plate 2 and the second lifting plate 7 can only move in the upward or downward direction. The first servo motor 3 and the second servo motor 4 are fixedly installed on the side of the first lifting plate 2 away from the T-shaped slider 8.

[0028] Specifically, the operation of the electric telescopic rod 12 drives the installation box 13 to slide on the inner bottom surface of the U-shaped base 1, and the sliding of the installation box 13 drives the T-shaped cleaning plate 14 to slide, thereby cleaning the waste on the inner bottom surface of the U-shaped base 1, and the movement of the installation box 13 drives the fixed rod 16 to move, and the movement of the fixed rod 16 drives the first connecting rod 17 to rotate, and the rotation of the first connecting rod 17 drives the connecting plate 9, the first lifting plate 2 and the second lifting plate 7 to move upward, thereby driving the roller 6 to move upward, and when the roller 6 moves to the highest position, the T-shaped cleaning plate 14 completes the cleaning of the waste, and the operation of the electric telescopic rod 12 drives the installation box 13 and the T-shaped cleaning plate 14 to move back to their original positions, thereby causing the roller 6 to move downward back to its original position, and during the movement of the T-shaped cleaning plate 14, the T-shaped cleaning plate 14, the scraper 15 and the fixed rod 16 never contact the roller 6, thereby preventing the roller 6 from blocking the movement of the T-shaped cleaning plate 14.

[0029] like Figure 1-Figure 5 As shown, a rubber baffle 10 is fixedly provided on the inner side of the connecting plate 9, and the rubber baffle 10 can limit the movement range of the rubber during rubber mixing. A scraper 15 is installed on the top of the T-shaped cleaning plate 14, and a mounting plate 24 is fixedly provided on the bottom surface of the scraper 15. The top surface of the mounting plate 24 is provided with bolts 25 that penetrate to the bottom surface. The bolts 25 are threadedly connected to the mounting plate 24 and the T-shaped cleaning plate 14 respectively. The mounting plate 24 cooperates with the bolts 25 to facilitate the disassembly and replacement of the scraper 15. A positioning plate 23 is fixedly provided on the side of the T-shaped cleaning plate 14 close to the mounting box 13. When the electric telescopic rod 12 is operated to move the T-shaped cleaning plate 14 to the bottom of the roller 6, the scraper 15 of a specified height is installed on the top of the T-shaped cleaning plate 14, so that the top of the scraper 15 is close to the outside of the roller 6, and the first servo motor 3 or the second servo motor 4 is operated to drive the roller 6 to rotate, and the scraper 15 can scrape the residual rubber on the surface of the rotating roller 6.

[0030] like Figure 1-Figure 5As shown, a disassembly assembly is arranged outside the T-shaped cleaning plate 14, and the disassembly assembly consists of a push rod 18, a spring 19, a second connecting rod 20, a clamping plate 21 and an insertion rod 22. A symmetrical insertion rod 22 is arranged inside the T-shaped cleaning plate 14, and a slot adapted to the insertion rod 22 is arranged on the side of the T-shaped cleaning plate 14. The insertion rod 22 is slidably connected to the T-shaped cleaning plate 14 through the slot. A clamping plate 21 is fixedly arranged outside the insertion rod 22, and the upper and lower sides of the clamping plate 21 are respectively slidably connected to the inner wall of the installation box 13, and symmetrical limit blocks are fixedly arranged on the top and bottom surfaces of the clamping plate 21. The installation box 13 is provided with limit grooves adapted to the limit blocks on the inner walls at the upper and lower sides. The limit blocks are slidably connected to the installation box 13 through the limit grooves. The limit blocks cooperate with the limit grooves to guide and limit the movement of the clamping plate 21. The installation box 13 is provided with a positioning groove adapted to the positioning plate 23 on the side. The positioning plate 23 is slidably connected to the installation box 13 through the positioning groove. A second connecting rod 20 is hinged on the inner side of the clamping plate 21.

The end of the spring 19 away from the pressing rod 18 is fixedly connected to the inner wall of the installation box 13. The operator presses the pressing rod 18 to drive the pressing rod 18 to move inside the installation box 13. The spring 19 is compressed, and the movement of the pressing rod 18 drives the second connecting rod 20 to rotate at the same time. The rotation of the second connecting rod 20 drives the clamping plate 21 to move in a direction away from each other. The movement of the clamping plate 21 drives the insertion rod 22 to move in a direction away from each other until the insertion rod 22 is released from the slot. In addition to limiting the position of the T-shaped cleaning plate 14, it is convenient to take out the T-shaped cleaning plate 14 for replacement. The replaced T-shaped cleaning plate 14 is put back in place, and the positioning plate 23 is aligned with the positioning slot and engaged into the positioning slot, and then the push rod 18 is released. The spring 19 pushes the push rod 18 to move outward, thereby driving the insertion rod 22 to approach each other until the insertion rod 22 is engaged into the slot, and the T-shaped cleaning plate 14 is limited and fixed again.
