Description

Technical Field

[0001] This invention relates to the field of rubber sealing strip technology, and more particularly to a device for removing burrs from rubber sealing strips. Background Technology

[0002] Rubber sealing strips utilize the elasticity of the lips, cavities, flanges, and other parts in their structure to generate contact pressure with the surfaces of assembled coupling parts (glass, metal parts, etc.) to achieve sealing and decorative functions.

[0003] However, some existing rubber sealing strips are prone to having burrs on both sides during the production process due to improper operation or other reasons. Burrs will seriously affect the sealing effect and normal use of the rubber sealing strip. Therefore, it is necessary to remove the burrs on both sides before use. However, the efficiency of traditional workers removing burrs by hand is low and it is not suitable for long-term operation. Summary of the Invention

[0004] This invention addresses the shortcomings of existing technologies by providing a device for removing burrs from rubber sealing strips. The specific technical solution is as follows:

[0005] A rubber sealing strip flash removal device includes a worktable; and a feeding assembly and a winding assembly located at both ends above the worktable. The feeding assembly is used to place the rubber sealing strip to be flash removed. The winding assembly is used in conjunction with the feeding assembly. During rotation, the winding assembly can wind up the rubber sealing strip, thereby moving the rubber sealing strip from the feeding assembly to the winding assembly. A flash removal assembly is located above the worktable between the feeding assembly and the winding assembly. The flash removal assembly includes a mounting frame, a scraping structure, and a grinding structure. The mounting frame is fixedly located at the middle axis along the length direction above the worktable. The mounting frame contains a scraping structure and a grinding structure that sequentially abut against the rubber sealing strip, used to scrape off the flash on both sides of the rubber sealing strip before friction and grinding.

[0006] As an improvement to the above technical solution, the feeding assembly includes a first bracket and a winding roller. The first brackets are fixed on both sides of one end of the worktable, and the winding roller is placed between the two first brackets for winding and placing the rubber sealing strip to be removed.

[0007] As an improvement to the above technical solution, the roll assembly includes a second bracket, a roll roller, and a servo motor. The second brackets are fixedly provided on both sides of the other end of the worktable. A roll roller is placed on top of one of the second brackets, and a servo motor is fixedly provided on the side of the other second bracket. The output end of the servo motor is fixedly provided with a sleeve that engages with the roll roller.

[0008] As an improvement to the above technical solution, several sets of baffles are equidistantly sleeved on the outer periphery of the winding roller and the coiling roller to separate the winding roller and the coiling roller into multiple independent parts, thereby preventing multiple sets of rubber sealing strips from tangling together.

[0009] As an improvement to the above technical solution, the scraping structure includes a scraping frame, a first moving plate and a scraper. The scraping frame has several scraping grooves that are horizontally and equidistantly arranged. The first moving plate is slidably arranged on both sides of the scraping groove, and the scraper that abuts against the rubber sealing strip is evenly distributed on the side of the first moving plate.

[0010] As an improvement to the above technical solution, the grinding structure includes a grinding frame, a second movable plate and a grinding disc. A grinding groove is provided in the grinding frame at the position corresponding to the scraping groove. The second movable plate is slidably provided on both sides of the grinding groove, and a grinding disc that abuts against the rubber sealing strip is fixedly provided on the side of the second movable plate.

[0011] As an improvement to the above technical solution, the scraper and the grinding frame are arranged in parallel, and the scraper and the grinding frame are respectively fixedly connected to the inner side of the mounting frame.

[0012] As an improvement to the above technical solution, the first moving plate and the second moving plate are respectively fixedly provided with support columns on the same side of the same direction, and the two sides of the mounting frame are respectively fixedly provided with cylinders that are fixedly connected to the adjacent support columns at the positions of the scraper or the grinding frame.

[0013] As an improvement to the above technical solution, a slag discharge hole is provided in the workbench directly below the slag removal assembly, and a slag receiving box is also slidably provided in the workbench.

[0014] The beneficial effects of this invention are:

[0015] 1. By installing a flash removal assembly above the workbench, which includes a scraping structure and a grinding structure, the rubber sealing strip is first passed through the scraping groove of the scraping frame and then through the grinding groove of the grinding frame. Then, depending on the width of the rubber sealing strip, two sets of cylinders can be synchronously adjusted to move the first and second moving plates simultaneously. This allows the two sets of first or second moving plates to approach or separate, so that the scraper on the side of the first moving plate contacts the rubber sealing strip. During the movement of the rubber sealing strip, the scraper can scrape off the flash on both sides of the rubber sealing strip. Then, the grinding disc on the side of the second moving plate rubs against the sides of the rubber sealing strip to produce a grinding effect. After removing the flash, the removed flash marks are ground, thereby improving the sealing performance and aesthetics of the rubber sealing strip. This equipment can automatically remove the flash from rubber sealing strips, saving manpower and being suitable for long-term operation.

[0016] 2. Furthermore, by providing a feeding assembly and a winding assembly at both ends above the workbench, the rubber sealing strip with the burrs to be removed can be wound around the winding roller and placed on the first support. The other end first passes through the scraping groove and the grinding groove and then is wound around the winding roller. One end of the winding roller is placed on the second support, and the other end is stuck in the sleeve. Then, the servo motor drives the sleeve to rotate, which in turn drives the winding roller to rotate. This allows the burrs to be removed and the rubber sealing strip to be ground during the movement, and it is also easy to collect. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0022] like Figure 1 , Figure 2 and Figure 3 As shown, Figure 1 This is a front view of the overall structure of the present invention; Figure 2 This is a top view of the workbench structure in this invention; Figure 3 This is a top cross-sectional view of the burr removal component in this invention.

[0023] The flash removal device for rubber sealing strips includes a workbench 10, a feeding assembly 20, a winding assembly 30, and a flash removal assembly 40.

[0024] like Figure 1 and Figure 2 As shown, Figure 1 This is a front view of the overall structure of the present invention; Figure 2 This is a top view of the workbench structure in this invention.

[0025] The workbench 10 has a feeding assembly 20 and a winding assembly 30 at its two ends. The feeding assembly 20 is used to place the rubber sealing strip to be removed. The winding assembly 30 is used in conjunction with the feeding assembly. During the rotation of the winding assembly 30, the rubber sealing strip can be wound up, thereby moving the rubber sealing strip from the feeding assembly 20 to the winding assembly 30.

[0026] Several sets of baffles 221 are equidistantly sleeved on the outer periphery of the winding roller 22 and the winding roller 32 to divide the winding roller 22 and the winding roller 32 into multiple independent parts, so that multiple rubber sealing strips can be wound in independent spaces respectively, thereby preventing multiple sets of rubber sealing strips from tangling together.

[0027] like Figure 1 and Figure 2 As shown, Figure 1 This is a front view of the overall structure of the present invention; Figure 2 This is a top view of the workbench structure in this invention.

[0028] The feeding assembly 20 includes a first bracket 21 and a winding roller 22. The first bracket 21 is fixedly provided on both sides of one end of the worktable 10, and the winding roller 22 is placed between the two first brackets 21 for winding the rubber sealing strip to be removed.

[0029] The roll assembly 30 includes a second bracket 31, a roll roller 32, and a servo motor 33. The second bracket 31 is fixedly provided on both sides of the other end of the worktable 10. The roll roller 32 is placed on the top of one of the second brackets 31, and the servo motor 33 is fixedly provided on the side of the other second bracket 31. The output end of the servo motor 33 is fixedly provided with a sleeve 331 that engages with the roll roller 32.

[0030] With a feeding assembly 20 and a winding assembly 30 respectively located at both ends above the workbench 10, the rubber sealing strip with the flash removed can be wound around the winding roller 22 and placed on the first support 21. The other end first passes through the scraping groove 422 and the grinding groove 432 and then wound around the winding roller 32. One end of the winding roller 32 is placed on the second support 31, and the other end is stuck in the sleeve 331. Then, the servo motor 33 drives the sleeve 331 to rotate, which can drive the winding roller 32 to rotate. This allows the rubber sealing strip to be moved while the flash is removed and ground, and it is also easy to collect.

[0031] like Figure 2 and Figure 3 As shown, Figure 2 This is a top view of the workbench structure in this invention; Figure 3 This is a top cross-sectional view of the burr removal component in this invention.

[0032] Above the workbench 10, between the feeding assembly 20 and the winding assembly 30, is a flash removal assembly 40. The flash removal assembly 40 includes a mounting frame 41, a scraping structure 42, and a grinding structure 43. The mounting frame 41 is fixedly located above the workbench 10 along the middle axis of the length direction. The mounting frame 41 contains a scraping structure 42 and a grinding structure 43 that sequentially abut against the rubber sealing strip. These structures are used to scrape off the flash on both sides of the rubber sealing strip before friction grinding.

[0033] The scraping structure 42 includes a scraping frame 421, a first moving plate 423 and a scraper 424. The scraping frame 421 has several scraping grooves 422 horizontally and equidistantly arranged inside. The first moving plate 423 is slidably arranged on both sides of the scraping groove 422, and the scraper 424 that abuts against the rubber sealing strip is evenly distributed on the side of the first moving plate 423.

[0034] The grinding structure 43 includes a grinding frame 431, a second movable plate 433, and a grinding disc 434. A grinding groove 432 is provided in the grinding frame 431 at the position corresponding to the scraper groove 422. The second movable plate 433 is slidably provided on both sides of the grinding groove 432, and the grinding disc 434 is fixedly provided on the side of the second movable plate 433 to abut against the rubber sealing strip.

[0035] On the same side of the first moving plate 423 and the second moving plate 433 in the same direction, a support column 441 is fixedly provided. On both sides of the mounting frame 41, a cylinder 44 is fixedly connected to the adjacent support column 441, corresponding to the position of the scraper frame 421 or the grinding frame 431.

[0036] By providing a flash removal assembly 40 above the workbench 10, which includes a scraping structure 42 and a grinding structure 43, the rubber sealing strip is passed through the scraping groove 422 of the scraping frame 421 and then through the grinding groove 432 of the grinding frame 431. Then, according to the width of different rubber sealing strips, the two sets of cylinders 44 can be synchronously adjusted to move the first moving plate 423 and the second moving plate 433 simultaneously. This allows the two sets of first moving plates 423 or the two sets of second moving plates 433 to move closer or further apart, so that the first moving plate 423 side... After the scraper 424 on the surface comes into contact with the rubber sealing strip, the scraper 424 can scrape off the burrs on both sides of the rubber sealing strip during the movement of the rubber sealing strip. Then, the grinding disc 434 on the side of the second moving plate 433 can be used to rub against the sides of the rubber sealing strip to produce a grinding effect. After removing the burrs from the rubber sealing strip, the removed burr marks are then ground, thereby improving the sealing performance and aesthetics of the rubber sealing strip. This equipment can automatically remove the burrs from the rubber sealing strip, which not only saves manpower but is also suitable for long-term operation.

[0037] In order for the rubber sealing strip to pass through the scraper 421 and the grinding frame 431 in sequence, the scraper 421 and the grinding frame 431 are arranged in parallel, and the scraper 421 and the grinding frame 431 are respectively fixedly connected to the inner side of the mounting frame 41.

[0038] like Figure 1 and Figure 2 As shown, Figure 1 This is a front view of the overall structure of the present invention; Figure 2 This is a top view of the workbench structure in this invention.

[0039] The workbench 10 has a slag discharge hole 11 located directly below the slag removal assembly 40. A slag collection box 12 is also slidably installed inside the workbench 10, which allows the removed rubber slag or dust generated during the grinding process to fall from the slag discharge hole 11 into the slag collection box 12, thus keeping the surface of the workbench 10 clean and facilitating the collection of these debris.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
