Description

Technical Field

[0001] This application relates to the field of basketball tire grinding equipment, for example, to a tire surface grinding device. Background Technology

[0002] Currently, during the production process of basketball mid-tire, vulcanization residue often adheres to the surface of the mid-tire after it is vulcanized by a mold. Furthermore, the smooth surface of the formed mid-tire is not conducive to the subsequent bonding of the rubber layer. Therefore, the surface of the mid-tire needs to be polished to increase its roughness. Traditional mid-tire polishing machines can clamp the mid-tire and polish the sides by rotating it.

[0003] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art:

[0004] When the intermediate tire is being clamped and rotated for grinding, the clamped part cannot be effectively ground. It is necessary to turn and position the intermediate tire after one revolution of grinding so that the unground area can be ground a second time. Summary of the Invention

[0036] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0037] Combination Figure 1-4 As shown, this embodiment of the present disclosure provides a tire surface polishing device, including: a frame 100, which is a rectangular frame structure, and a vertical frame 101 is provided on the upper part of the frame 100; a slide 200, which is a rectangular frame structure, and the slide 200 is slidably disposed within the frame 100; two support rollers 300, which are symmetrically disposed on both sides inside the slide 200 and are relatively parallel to each other; a polishing frame 400, which is disposed on both sides of the slide 200 and has a polishing belt 401 disposed on it; and a clamping frame 500, which is hinged to the vertical frame 101 on both sides of the frame 100, and has a pressure roller 502 at its end, which is swayably disposed on the upper part of the support roller 300.

[0038] The tire surface polishing device provided in this embodiment has a rectangular frame structure for the frame 100. A slide 200 is laterally slidable inside the frame 100, allowing it to slide back and forth within the frame 100. A vertical frame 101 is located at the top of the frame 100. Two support rollers 300 are symmetrically arranged parallel to each other on both sides of the slide 200, supporting the tire. The tire can roll along its axis between the two support rollers 300, and the rotation of the support rollers 300 causes the tire to roll smoothly on them. A grinding frame 400 is positioned on both sides of the slide 200. A grinding belt 401 is fitted onto the upper part of the grinding frame 400. The grinding belt 401 is positioned above the support roller 300 and contacts the surface of the intermediate tire. The grinding belt 401 can uniformly grind the surface of the intermediate tire, effectively roughening the surface and improving its roughness, which facilitates subsequent bonding processes. Two clamping frames 500 are oscillatingly mounted on the upright frame 101, respectively hinged symmetrically on both sides of the upright frame 101. The clamping frames 500 are positioned above the slide 200. A pressure roller 502 is rotatably mounted at the end of each clamping frame 500, and the pressure roller 502 oscillates with the clamping frame 500 on the upright frame 101. The pressure roller 502 can swing to the upper part of the support roller 300. The two pressure rollers 502 can press the intermediate tire onto the support roller 300. In this way, the two lower support rollers 300 and the two upper pressure rollers 502 work together to clamp and position the intermediate tire, preventing it from radially running or axially moving during the grinding process. The rotation of the support roller 300 can drive the intermediate tire to rotate between the support roller 300 and the pressure roller 502. In this way, the grinding belts 401 on both sides can grind the surface of the rotating intermediate tire. The slide 200 can drive the support roller 300 to reciprocate along the length of the frame 100 below the clamping roller. When the slide 200 reciprocates, the intermediate tire is clamped between the support roller 300 and the pressure roller 502. The rollers 300 and 502 roll between each other. When grinding begins, the support roller 300 and the pressure roller 502 are positioned opposite each other. When grinding begins, the support roller 300 drives the intermediate tire to rotate, and the slide 200 moves synchronously along the length of the frame 100. The pressure roller 502 remains stationary. In this way, the intermediate tire can roll between the support roller 300 and the pressure roller 502 along the length of the frame 100. When the slide 200 drives the support roller 300 to move along the length of the frame 100, the support roller 300 and the pressure roller 502 separate and interleave. In this way, the intermediate tire above the support roller 300 is freed from the constraint of the pressure roller 502. The intermediate tire is freed from the support roller 300 and rolls down from one side of the slide 200 to the collection area below, completing the automatic unloading process after grinding.

[0039] Optionally, a clamping cylinder 102 is hinged to the upper part of the upright frame 101, and the other end of the clamping cylinder 102 is hinged to the end of the clamping frame 500 near the pressure roller 502.

[0040] In this way, the clamping cylinder 102 on the upper part of the stand 101 can drive the clamping frame 500 to swing around the hinge point, so as to realize the clamping roller 502 to press and release the intermediate tire. Furthermore, by activating the clamping cylinder 102, the clamping roller 502 can be lifted to facilitate the insertion or removal of the intermediate tire. After the intermediate tire is inserted, the clamping cylinder 102 is activated to make the clamping roller 502 fall down, so as to stably press the intermediate tire onto the support roller 300 and ensure that the position is fixed during the grinding process.

[0041] Optionally, the grinding frame 400 is slidably disposed on the side of the slide 200, and the slide 200 is provided with a sliding rail 201 on its upper part. The sliding rail 201 extends along the width direction of the slide 200, and the grinding frame 400 and the slide 200 are slidably connected through the sliding rail 201. A sliding cylinder 203 is provided at the bottom of the slide 200, with one end of the sliding cylinder 203 disposed on the slide 200 and the other end of the sliding cylinder 203 disposed on the grinding frame 400.

[0042] In this way, the grinding frames 400 are slidably arranged on both sides of the carriage 200, and the two grinding frames 400 are positioned opposite each other. When the intermediate tire falls onto the support roller 300 between the two grinding frames 400, the sliding cylinder 203 is activated, pushing the grinding frames 400 along the sliding track 201 towards both sides of the intermediate tire, so that the grinding belt 401 contacts the surface of the intermediate tire, achieving precise grinding of the outer circumference of the intermediate tire. The sliding track 201 on the upper part of the carriage 200 can provide guidance for the sliding of the grinding frames 400. The sliding cylinder 203 at the bottom of 200 is connected to the grinding frame 400. The extension and retraction of the sliding cylinder 203 can drive the grinding frame 400 to move along the sliding track 201, thereby adjusting the contact pressure between the grinding belt 401 and the surface of the intermediate tire to ensure uniform and stable grinding. After grinding is completed, the sliding cylinder 203 retracts, driving the grinding frame 400 away from the intermediate tire along the sliding track 201, releasing the contact between the grinding belt 401 and the intermediate tire, which facilitates the subsequent support roller 300 to drive the intermediate tire to roll and unload.

[0043] Optionally, the upper two ends of the grinding frame 400 are provided with grinding wheels 402, and a grinding belt 401 is sleeved on the grinding wheels 402. The grinding belt 401 is an annular belt structure.

[0044] In this way, large grinding wheels 402 are provided at both ends of the upper part of the grinding frame 400. The length of the grinding frame 400 is greater than the length of the slide 200. Grinding wheels 402 are provided at both ends of the grinding frame 400. An annular grinding belt 401 is sleeved between the two grinding wheels 402 to form a continuous grinding surface. The two grinding wheels 402 support the grinding belt 401 to keep it taut. In this way, when the grinding belt 401 is pressed on the surface of the intermediate tire, the grinding belt 401 can be fully in contact with the surface of the intermediate tire.

[0045] Optionally, a tensioning frame 403 is slidably mounted on one end of the grinding frame 400, and one of the two grinding wheels 402 is mounted on the tensioning frame 403 and the other on the grinding frame 400; a tensioning slide rod 404 is provided on one end of the grinding frame 400 near the tensioning frame 403, the tensioning frame 403 is slidably mounted on the tensioning slide rod 404, a tensioning cylinder 405 is provided on the tensioning frame 403, and the driving end of the tensioning cylinder 405 is connected to the grinding frame 400.

[0046] In this way, the tensioning frame 403 on one side of the grinding frame 400 is slidably mounted on the tensioning slide rod 404, which is located at one end of the grinding frame 400. A tensioning cylinder is positioned between the tensioning frame 403 and the grinding frame 400. The extension and retraction of the tensioning cylinder 405 causes the tensioning frame 403 to slide along the tensioning slide rod 404, thereby adjusting the distance between the tensioning frame 403 and the other end of the grinding frame 400. This achieves tension adjustment of the grinding belt 401. Furthermore, the precise control of the tensioning cylinder 405 ensures that the grinding belt 401 maintains stable tension during high-speed operation, preventing uneven grinding or misalignment due to loosening. The tensioning cylinder allows for easy replacement of the grinding belt 401 by extending and retracting. By shortening the tensioning cylinder, the tensioning frame 403 can be brought closer to the grinding frame 400 body, thereby loosening the grinding belt 401 and making it easier to remove or install it from the grinding wheel 402. After replacement, the tensioning cylinder 405 extends to reapply tension, ensuring that the grinding belt 401 is firmly attached to the grinding wheel 402. There are two grinding wheels 402, one set on the tensioning frame 403 and the other fixed on the grinding frame 400 body. The relative positions of the two can be adjusted by the tensioning cylinder 405 to ensure that the grinding belt 401 is always in the optimal tension state during operation.

[0047] Optionally, a baffle 204 is provided on one side of the upper part of the slide 200, and an adjustment frame 205 is provided in the extension direction of the bottom of the slide 200. A swing plate 206 is hinged on the adjustment frame 205 near the baffle 204, and a swing cylinder 207 is hinged on the slide 200. The other end of the swing cylinder 207 is hinged to the swing plate 206.

[0048] Thus, a baffle 204 is provided on one side of the slide 200, and a swing plate 206 is provided on the bottom of the slide 200 near the baffle 204. When the end of the slide 200 with the swing plate 206 is positioned below one end of the pressure roller 502, the pressure roller 502 is raised, and the intermediate tire can fall onto the upper part of the support roller 300. The baffle 204 and the swing plate 206 can restrict the intermediate tire to one end of the support roller 300. In this way, when the pressure roller 502 presses down, it can prevent the intermediate tire from rolling and displacing on the support roller 300. When the pressure roller 502 has finished pressing down, the pressure roller 502 and the support roller 300 clamp and stabilize the intermediate tire. The swing plate 206 is hinged on the adjusting frame 205 at the bottom of the slide 200. The 06 can swing on the adjusting frame 205. The swing cylinder 207, which is hinged on the slide 200, is driven and hinged to the swing plate 206. The extension and retraction of the swing cylinder 207 drives the swing plate 206 to swing on the adjusting frame 205, thereby adjusting the angle between the swing plate 206 and the baffle 204, thus limiting the position of the intermediate tire. After the clamping roller 502 and the support roller 300 have finished clamping the intermediate tire, the swing rod pushes the swing plate 206 to the side away from the baffle 204, increasing the angle between the swing plate 206 and the baffle 204, thereby releasing the axial constraint on the intermediate tire, so that the intermediate tire can rotate and move freely on the support roller 300.

[0049] Optionally, the slide 200 is provided with driven wheels 208 on its side. There are two driven wheels 208, which are coaxially connected to the support rollers 300 respectively. The slide 200 is provided with a drive motor 209 at its bottom. The drive motor 209 is provided with a drive wheel 210, which is synchronously connected to the two driven wheels 208 through a chain 211.

[0050] In this way, the drive motor 209 is set at the bottom of the adjustment frame 205 at the bottom of the slide 200, and the two support rollers 300 on the slide 200 are each provided with driven wheels 208. The drive wheel 210 on the drive motor 209 is synchronously connected to the two driven wheels 208 through the chain 211 to ensure that the rotation of the support rollers 300 on both sides is consistent.

[0051] Optionally, the upper part of the upright frame 101 is provided with guide rods 103. There are two guide rods 103, which are located on both sides of the clamping frame 500 respectively. The distance between the guide rods 103 is less than the diameter of the ball. The end of the guide rod 103 is connected to a feeding ring 104. The diameter of the feeding ring 104 is greater than the diameter of the ball. The feeding ring 104 is located at one end of the upper part of the pressing roller 502.

[0052] Thus, two guide rods 103 are provided on the upper part of the upright frame 101. The distance between the guide rods 103 is smaller than the diameter of the intermediate tire ball, which allows the intermediate tires to roll through side by side. The feed ring 104 is located above the pressure roller 502 and has a diameter larger than the diameter of the intermediate tire ball. The feed ring 104 can position the intermediate tire and roll it between the pressure roller 502 and the support roller 300, ensuring that the intermediate tire is accurately positioned when it enters the clamping area.

[0053] Optionally, the support roller 300 is provided with an anti-slip layer 301 on the outside. The anti-slip layer 301 is made of rubber and has uniformly distributed anti-slip textures on its surface.

[0054] In this way, the anti-slip layer 301 on the outside of the support roller 300 is made of rubber and has uniformly distributed anti-slip texture, which effectively increases the friction between the support roller 300 and the intermediate tire, preventing the intermediate tire from slipping or shifting during rotation. In addition, the elasticity of the rubber material can also buffer the contact stress between the intermediate tire and the support roller 300, making the contact between the intermediate tire and the support roller 300 more gentle and tight, effectively increasing the contact area between the intermediate tire and the support roller 300, and preventing the intermediate tire from shifting or sliding when the grinding belt 401 grinds the intermediate tire.

[0055] Optionally, a guide slide rod 105 is provided inside the frame 100, the slide 200 is slidably mounted on the guide slide rod 105, a threaded rod 106 is rotatably mounted on the frame 100, a threaded sleeve 107 is provided at the bottom of the slide 200, the threaded sleeve 107 is threadedly connected to the threaded rod 106, and a sliding motor 108 is provided on the side of the frame 100, the sliding motor 108 is drivenly connected to the threaded rod 106.

[0056] In this way, the guide rods 103 inside the frame 100 are arranged in the extension direction, and there are two guide rods 103 arranged on both sides of the frame 100. The slide 200 is slidably sleeved on the guide rods 103 to ensure the stability of the slide 200 in linear reciprocating movement. The bottom of the slide 200 is provided with a threaded sleeve 107, and the bottom of the frame 100 is provided with a threaded rod 106 in the extension direction. The threaded sleeve 107 is sleeved on the threaded rod 106 and threadedly engaged with it. When the sliding motor 108 drives the threaded rod 106 to rotate, the slide 200 is driven to make linear reciprocating movement along the guide slide rod 105 through threaded transmission, so as to achieve precise control of the grinding stroke and ensure that the grinding belt 401 can evenly cover the surface of the intermediate tire, thereby improving the grinding accuracy and consistency.
