TECHNICAL FIELD
[0001] The utility model relates to a buffering stop block trimming mechanism and belongs to the field of buffering stop block trimming. BACKGROUND
[0002] The buffering stop block is usually made of rubber, polyurethane or other elastic materials, and is usually made by using a mold. When the material is injected into the mold for production and molding, the excess rubber and other materials will overflow from the gap. After cooling and setting, burrs are formed on the outer wall of the buffering stop block. In the prior art, the buffering stop block is usually designed in a corrugated shape. When trimming the buffering stop block, a trimming mold matching the shape of the buffering stop block is needed. After the burrs on the edge of the buffering stop block are trimmed by the blade, the burrs will accumulate on the trimming table. When the burrs accumulated on the trimming table are too much, they will block the path of the blade when trimming around the buffering stop block, thereby reducing the trimming efficiency of the burrs on the buffering stop block. Therefore, it is necessary to design a buffering stop block trimming mechanism that can reduce the accumulation of trimmed burrs on the trimming table. SUMMARY

DETAILED DESCRIPTION
[0020] In order to make the technical means, creative features, purposes and effects achieved by the present application easy to understand, the present application will be further described below in conjunction with specific embodiments.
[0021] Please refer to Figures 1-5This utility model provides a technical solution: a buffer stop block trimming mechanism, including a trimming table 1, two symmetrically mounted support legs 2 at the bottom of the trimming table 1, an installation groove 12 on the top of the trimming table 1, a fixing ring 8 installed inside the installation groove 12, a limit post 4 installed on the top of the trimming table 1, a buffer stop block 3 sleeved on the limit post 4, a support plate 6 installed above the fixing ring 8, an installation plate 7 installed on the side of the support plate 6 near the buffer stop block 3, and the side of the installation plate 7 away from the support plate 6 fitting against the outer wall of the buffer stop block 3. Both sides of the mounting plate 7 are equipped with trimming blades 11, both sides of the support plate 6 are equipped with cleaning plates 9, the rear side of the mounting plate 7 is equipped with a fixing component, the lower side of the fixing ring 8 is equipped with a transmission structure, and the upper side of the buffer stop block 3 is equipped with a positioning ring 5. The positioning ring 5 is threaded onto the limiting post 4. Through the cooperation of the limiting post 4 and the positioning ring 5, the buffer stop block 3 can be fixed above the trimming table 1, so as to prevent the buffer stop block 3 from rotating with the transmission direction of the trimming blades 11 during the trimming of the rough edges of the buffer stop block 3 by the fixing ring 8 driving the trimming blades 11.
[0022] Please see Figure 2 and Figure 5 The fastener includes an extension rod 19, which is installed on the side of the mounting plate 7 near the support plate 6. A fixed base 20 is installed on the end of the extension rod 19 away from the mounting plate 7. The end of the fixed base 20 away from the extension rod 19 is installed on the support plate 6. A movable groove 21 is opened inside the fixed base 20. The end of the extension rod 19 away from the mounting plate 7 is inserted into the movable groove 21. A spring 22 is installed inside the movable groove 21. The other end of the spring 22 is installed on the extension rod 19. A limit block 23 is installed on the side of the fixed base 20 near the support plate 6. The limit block 23 is inserted into the support plate 6. Screw holes 24 are opened on both the limit block 23 and the support plate 6. Fixing screws 10 are installed inside the screw holes 24. The limit block 23 and the support plate 6 are installed by fixing screws 10, so that the trimming blade 11 can be removed and replaced when trimming different models of buffer stop blocks 3.
[0023] Please see Figure 3 and Figure 4The transmission structure includes a motor 17, which is installed at the bottom of the trimming table 1. A transmission rod 18 is installed at the output end of the motor 17, and a gear 13 is installed on the transmission rod 18. The end of the transmission rod 18 away from the motor 17 is installed at the bottom of the fixed ring 8. A gear ring 15 is installed inside the mounting groove 12, and the gear ring 15 and the gear 13 mesh with each other. Slide strips 16 are installed on both the outer and inner walls of the fixed ring 8. Slide grooves 14 are opened on both the outer and inner walls of the mounting groove 12. Two slide strips 16 are installed inside the two slide grooves 14 respectively. Through the cooperation of the slide grooves 14 and slide strips 16, the position of the fixed ring 8 and the trimming table 1 can be restricted, so that the fixed ring 8 can always rotate inside the mounting groove 12, thereby improving the stability of the fixed ring 8 driving the cleaning plate 9 to rotate.
[0024] Detailed Implementation: The motor 17 drives the gear 13 to rotate. Simultaneously, the gear 13 rotates along with the outer wall of the gear ring 15, thereby causing the fixed ring 8 to rotate on the trimming table 1. This, in turn, causes the trimming blade 11 to rotate along with the outer wall of the buffer stop block 3, trimming the protruding burrs on the edge of the buffer stop block 3. Slides 16 are installed on both the inner and outer walls of the fixed ring 8. These slides 16 are installed within grooves 14 on the trimming table 1, restricting the movement trajectory of the fixed ring 8 and the trimming table 1. This allows the trimming blade 11 to smoothly trim the burrs on the outer wall of the buffer stop block 3. A cleaning plate 9 is provided on the side of the support plate 6 installed on the fixed ring 8. While the fixed ring 8 drives the trimming blade 11 to trim the protruding burrs on the outer wall of the buffer stop block 3, the cleaning plate 9 pushes the trimmed burrs to accumulate on the cleaning plate 9. On the side, because the cleaning plate 9 continuously follows the rotation of the fixed ring 8, the inertia generated during rotation can transport the burrs accumulated on one side of the cleaning plate 9 to the outside of the trimming table 1, thereby reducing the accumulation of burrs after trimming on the trimming table 1 and improving the trimming effect of the trimming blade 11 on the outer wall of the buffer stop block 3. Through the cooperation of the spring 22 and the extension rod 19, the extension rod 19 can be pushed outward by the thrust generated by the spring 22, so that the trimming blade 11 is always in contact with the outer wall of the buffer stop block 3, which is convenient for trimming the protruding burrs on the buffer stop block 3. In addition, a limit block 23 is installed on one side of the fixed base 20. The limit block 23 is installed inside the support plate 6 by the fixing screw 10. When it is necessary to trim the burrs of different models of buffer stop blocks 3, it is convenient to replace the trimming blade 11, improving the replacement efficiency of the trimming blade 11.
