Description

Technical Field

[0001] This utility model relates to the field of rubber seal trimming technology, and more specifically, to a rubber seal trimming device. Background Technology

[0002] In the manufacturing process of rubber seals, trimming is a key step. After the rubber seals are molded, their edges often have excess burrs, flash, and other defects. These defects not only affect the appearance quality of the seals, but also negatively impact their sealing performance, reducing the reliability and service life of the seals in actual use. Therefore, trimming is necessary to remove these excess parts and ensure that the edges of the seals are flat and smooth, achieving the dimensional accuracy and surface quality required by the design.

[0003] Belt sanders are commonly used equipment. They remove burrs and flash by using a rotating belt to rub against the edges of rubber seals. However, existing belt sanders have some shortcomings when used for trimming rubber seals. For example, adjusting the belt tension is not convenient, and replacing the belt is difficult, requiring disassembly of multiple parts and consuming a lot of time and manpower. Therefore, we have made improvements and proposed a rubber seal trimming device. Utility Model Content

One end of the connecting rod 204 is fixedly connected to a sleeve 203, and the sleeve 203 is welded to the connecting rod 204. The middle part of the sleeve 203 is rotatably connected to a threaded rod 202 through a bearing. A first support member is provided between the threaded rod 202 and the first support plate 101. A limiting plate 207 is fixedly sleeved on the outer surface of the connecting rod 204, and the limiting plate 207 is slidably connected to the side of the second support plate 105. The limiting plate 207 can limit the connecting rod 204 to prevent the connecting rod 204 from rotating around the threaded rod 202 and disengaging from the inclined groove 205 when the threaded rod 202 rotates. There are two limiting plates 207, which are located on both sides of the second support plate 105 respectively. The limiting plates 207 are welded to the connecting rod 204.

[0027] Rotating the threaded rod 202 can drive the sleeve 203 and the connecting rod 204 to rise and fall. When the connecting rod 204 rises and falls, it can drive the second support plate 105 to rotate around the connecting threaded rod 104. When the second support plate 105 rotates, it can adjust the distance between the driven roller 106 and the driving roller 103, thereby adjusting the tension of the sanding belt 108. The operation is convenient. When replacing the sanding belt 108, simply reduce the distance between the driven roller 106 and the driving roller 103 to loosen the sanding belt 108, and pull the sanding belt 108 away from the first support plate 101 to remove and replace it.
