[0027] Please refer to Figures 1 to 4 As shown, the present utility model provides a rubber seal grinding device to solve the problems that for currently large-sized rubber seals, manual deburring is mostly used, and long-term grinding not only has low efficiency, but also is prone to product damage due to muscle fatigue. At the same time, the tools used in manual grinding are also very easy to damage the product, resulting in product scrapping. Specifically, the rubber seal grinding device 100 includes a base 10, a grinding assembly 20, and a driving assembly 30. The grinding assembly 20 and the driving assembly 30 are both installed on the base 10, and the driving assembly 30 is respectively arranged on both sides of the grinding assembly 20. The driving assembly 30 is used to drive the seal 101 to be ground to move, and the grinding assembly 20 is used to grind the seal 101 to be ground during the movement of the seal 101 to be ground, so as to grind the burrs of the rubber seal and the like.

[0028] Please refer to Figures 1 to 4As shown, in this embodiment, the grinding assembly 20 includes a grinding wheel 21 and a grinding motor 22. The grinding motor 22 is connected to the grinding wheel 21 to drive the grinding wheel 21 to rotate, thereby realizing the grinding of the seal 101 to be ground. In this embodiment, the grinding wheels 21 are distributed on both sides of the seal 101 to be ground, and the grinding wheels 21 on both sides of the seal 101 to be ground correspond one by one to abut against the surface of the seal 101 to be ground. During the rotation of the grinding wheel 21, the grinding work of the seal 101 to be ground is realized. The two grinding wheels 21 on both sides of the seal 101 to be ground can realize the simultaneous grinding of the inner and outer sides of the seal 101 to be ground, greatly improving the grinding efficiency.

[0029] Please refer to Figures 1 to 4 As shown, in this embodiment, the driving assembly 30 includes a rotating wheel disc 31 and a driving motor 32. Among them, the rotating wheel disc 31 is distributed on both sides of the seal 101 to be ground, and the driving motor 32 is used to drive the rotating wheel disc 31 to rotate, thereby driving the seal 101 to be ground to move. In this embodiment, a groove 301 is provided along the circumferential direction on the outer circumference of the rotating wheel disc 31, and the groove 301 is adapted to the shape of the seal 101 to be ground, so as to better install the seal 101 to be ground and facilitate the rotating wheel disc 31 to drive the seal 101 to be ground to move.

[0030] Please refer to Figures 1 to 4 As shown, in this embodiment, the grinding wheel 21 and the rotating wheel disc 31 on at least one side of the seal 101 to be ground can move away from the seal 101 to be ground, so as to facilitate the placement of the seal 101 to be ground and the removal of the ground seal strip. For example, in this embodiment, the grinding wheels 21 and the rotating wheel disc 31 on both sides of the seal 101 to be ground are distributed vertically, that is, at least the grinding wheel 21 and the rotating wheel disc 31 on one side of the seal 101 to be ground can move up or down along the vertical direction, so as to facilitate the placement of the seal 101 to be ground and the removal of the ground seal strip.

[0031] Please refer to Figures 1 to 4 As shown, in this embodiment, the driving assembly 30 further includes a first bracket 33. The first bracket 33 is installed on the base 10. The rotating wheel disc 31 includes a driving wheel 311 and a driven wheel 312. The driving wheel 311 is connected to the driving motor 32, and the driven wheel 312 is connected to the first bracket 33 through a rotating shaft 313. Among them, the rotating shaft 313 is slidably connected to the first bracket 33, that is, the driven wheel 312 can move away from the seal 101 to be ground.

[0032] Please refer toFigures 1 to 4 As shown, in this embodiment, the grinding assembly 20 further includes a second bracket 23. The second bracket 23 is fixedly installed on the base 10. The grinding motor 22 is installed on the second bracket 23 and is connected to the grinding wheel 21 to drive the grinding wheel 21 to rotate. Among them, at least one of the two grinding motors 22 located on both sides of the seal 101 to be ground is slidably connected to the second bracket 23, that is, the grinding wheel 21 located on one side of the seal 101 to be ground can move away from the seal 101 to be ground.

[0033] It can be understood that when installing the seal 101 to be ground, the driven wheel 312 and one of the grinding wheels 21 can be slid along the first bracket 33 and the second bracket 23, so that there is enough clearance between the driven wheel 312 and the driving wheel 311 and between the two grinding wheels 21, so as to facilitate the installation of the seal 101 to be ground into the groove 301 of the driving wheel 311, and make the seal 101 to be ground pass through between the two grinding wheels 21.

[0034] Please refer to Figures 1 to 4 As shown, in this embodiment, the rotation direction of the grinding motor 22 needs to be the same as the moving direction of the seal 101 to be ground, and the rotational linear velocity of the grinding wheel 21 is greater than the moving speed of the seal 101 to be ground, so as to ensure the grinding effect of the grinding wheel 21 on the seal 101 to be ground. Further, in this embodiment, the rotating disks 31 in the driving assemblies 30 located on both sides of the grinding assembly 20 are in the same plane, so as to ensure that the path of the seal 101 to be ground is a straight line when it moves, and avoid the seal 101 to be ground from being damaged by the grinding wheel 21 due to disorder.

[0035] Please refer to Figures 1 to 4 As shown, in this embodiment, the seal 101 to be ground can be a strip-shaped sealing rubber strip or an annular sealing ring. When it is a strip-shaped sealing rubber strip, the grinding assembly 20 and the driving assembly 30 can be arranged in parallel, and the driving assembly 30 is arranged on both sides of the grinding assembly 20; when it is an annular sealing ring, two or more sets of driving assemblies 30 can be set. Among them, when two sets of driving assemblies 30 are set, they can be arranged in parallel with the grinding assembly 20 and are located on both sides of the grinding assembly 20. When more than two sets of driving assemblies 30 are set, multiple sets of the driving assemblies 30 can be arranged in an annular shape, and the grinding assembly 20 is located between two of the driving assemblies 30. The multiple sets of driving assemblies 30 arranged in an annular shape can better adapt to the annular sealing ring, ensure the smooth movement of the annular sealing ring, and thus realize the grinding of the annular sealing ring by the grinding assembly 20.

[0036] Please refer to Figures 1 to 4As shown in the figure, in this embodiment, taking the rotating wheel 31 in the driving assembly 30 including a driven wheel 312 and a driving wheel 311 distributed vertically, and the polishing assembly 20 including two polishing wheels 21 distributed vertically as an example, the working process of the polishing device 100 is as follows:

[0037] First, move the driven wheels 312 in the two groups of driving assemblies 30 and the upper polishing wheel 21 in the polishing assembly 20 upward;

[0038] Clamp the film joining line of the rubber seal to be polished in the groove 301 of the driving wheel 311, and make the film joining line of the rubber seal located above the lower polishing wheel 21 in the polishing assembly 20;

[0039] Move the driven wheel 312 downward to press it against the rubber seal to be polished;

[0040] Adjust the position of the upper polishing wheel 21 in the polishing assembly 20 to make it reach a position that meets the polishing requirements;

[0041] Turn on the power supply, so that the driving motor 32 drives the driving wheel 311 to rotate, the polishing motor 22 drives the polishing wheel 21 to rotate, and gradually increase the rotation speed of the polishing motor 22, so that the linear speed of the polishing wheel 21 is greater than the moving speed of the rubber seal to be polished, so as to polish the rubber seal to be polished until the polishing is completed;

[0042] After the polishing is completed, remove the polishing wheel 21 from the rubber seal so that it does not contact the rubber seal, and gradually reduce the rotation speed of the polishing motor 22. At the same time, reduce the rotation speed of the driving motor 32 until it stops, then remove the driven wheel 312 from the rubber seal, and take off the polished rubber seal.

[0043] The present utility model provides a rubber seal polishing device, which arranges a polishing assembly and a driving assembly on both sides of the rubber strip, and arranges the driving assembly on both sides of the polishing assembly respectively. The driving assembly drives the seal to be polished to move, and the polishing wheel rotates during the movement to polish the seal rubber strip, avoiding damage to the product surface during polishing, improving the product yield, and greatly improving the polishing efficiency at the same time.
