Description

Technical Field

[0001] This utility model belongs to the field of residual adhesive removal technology, and in particular relates to a device for cutting off residual adhesive from the edge of a rubber gasket. Background Technology

[0002] When rubber gaskets are vulcanized, residual rubber is usually formed at the edge of the gasket due to the influence of the mold fitting precision. Since the diameter and thickness of gaskets of different specifications vary, it is not convenient to remove the residual rubber using equipment. The existing process mainly involves manually cutting off the residual rubber at the edge of the gasket with a blade. However, manual cutting is not only inefficient, but also easy to damage the gasket if the cutting force of the blade is not well controlled. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a rubber gasket edge residual adhesive removal device, which helps improve the efficiency of removing residual adhesive and prevents damage to the gasket.

[0004] In order to achieve the purpose of this utility model, the following solution is proposed: A device for removing residual rubber from the edge of a rubber gasket includes: a rotary motor, a lifting device, and a cutter.

[0005] The rotary motor has a disc coaxially mounted on its main shaft, and the outer diameter of the disc is smaller than the outer diameter of the washer.

[0006] A cone is coaxially mounted on the top of the movable rod of the lifting device, with the small end of the cone facing the center. The cone rotates around the axis on the movable rod of the lifting device, and the disc is coaxial with the cone.

[0007] The cutter is located on one side of the disc, with its blade parallel to the disc's axis and facing in the opposite direction to the disc's rotation. The distance between the cutter and the disc's axis is adjustable.

[0008] The beneficial effects of this utility model are as follows: 1. This solution uses a drive motor to rotate the washer and removes the residual adhesive on the edge of the washer with a cutter. Compared with manual cutting, it has higher efficiency. In addition, this solution can remove the residual adhesive on both ends of the washer at the same time, which can further improve work efficiency. 2. This solution can accurately control the degree of residual adhesive removal by adjusting the distance between the blade and the disc, which can effectively prevent damage to the gasket.

[0018] like Figures 1 to 3 As shown, a rubber gasket edge residual adhesive removal device includes: a rotary motor 1, a lifting device 3, and a cutter 5.

[0019] The rotary motor 1 has a disc 2 coaxially mounted on its main shaft. The outer diameter of the disc 2 is smaller than the outer diameter of the washer.

[0020] A cone 4 is coaxially mounted on the top of the movable rod of the lifting device 3. The small end of the cone 4 faces the center. The cone 4 is mounted on the movable rod of the lifting device 3 and rotates around the axis. The disc 2 is coaxial with the cone 4.

[0021] The cutter 5 is located on one side of the disc 2. The blade of the cutter 5 is parallel to the axis of the disc 2, and the direction of the blade is opposite to the rotation direction of the disc 2. The distance between the cutter 5 and the axis of the disc 2 is adjustable.

[0022] During operation, the rubber washer is first placed on the cone 4. The small end of the cone 4 passes through the inner hole of the washer, and the lifting device 3 drives the movable rod to rise, thereby bringing the washer closer to the disc 2. The cone 4 and the disc 2 press the washer together. Through the positioning and pressing action of the cone 4 and the disc 2, the washer is kept in a horizontal position and coaxial with the disc 2, so that the axis of the washer is parallel to the blade of the cutter 5. Then, the rotary motor 1 is started, and the disc 2 will drive the washer to rotate around its axis. When the washer rotates, the cone 4 will rotate around its own axis on the movable rod. During the rotation of the washer, the distance between the cutter 5 and the disc 2 is adjusted so that the blade of the cutter 5 moves closer to the washer, and the blade is used to cut off the residual rubber on the edge of the washer.

[0023] The blade of the cutter 5 in this design is always parallel to the axis of the washer, which can remove residual adhesive from both ends of the washer at the same time, effectively improving the cutting efficiency. By adjusting the distance between the cutter 5 and the disc 2, it can adapt to the removal of residual adhesive from washers of different diameters; and by controlling the height of the cone 4 through the lifting device 3, it can adapt to washers of different thicknesses.

[0024] Preferred, such as Figures 1 to 3 As shown, the lower end of the disk 2 is a conical structure with the small end facing down, and the outer diameter of the small end is smaller than the inner diameter of the washer. This structure helps to improve the coaxiality accuracy between the washer and the spindle of the rotary motor 1, and helps to further improve the accuracy of removing residual adhesive from the washer, which can effectively avoid damaging the washer.

[0025] Preferred, such as Figure 1 , Figure 2 As shown, the lifting device 3 is located at the bottom of a workbench 6, the movable rod of the lifting device 3 passes upward through the workbench 6, and the rotary motor 1 is located above the workbench 6.

[0026] Preferred, such as Figure 1 , Figure 2As shown, the cutter 5 is connected to a bracket 51 by screws. A slide groove 61 is provided on the worktable 6. The lower end of the bracket 51 is slidably disposed in the slide groove 61. A lead screw 7 is parallel to the slide groove 61. The lead screw 7 passes through the bracket 51 through a threaded structure. By rotating the lead screw 7, the position of the bracket 51 in the slide groove 61 can be adjusted, thereby adjusting the distance between the cutter 5 and the axis of the disc 2. This adjustment method can precisely adjust the position of the cutter 5, which helps to improve the accuracy of removing residual glue from the edge of the washer. The lead screw 7 is manually driven.

[0027] Preferably, the lower end surface of the disk 2 and the outer conical surface of the cone 4 are provided with a rubber layer to increase the friction between them and the washer and prevent the washer from slipping when rotating.

[0028] The above description is merely a preferred embodiment of this utility model and does not imply its uniqueness or limitation. Those skilled in the art should understand that various changes or equivalent substitutions made to this utility model without departing from its scope are all within the protection scope of this utility model.
