Description

Technical Field

[0001] This utility model relates to auxiliary equipment for tire manufacturing, and more specifically, to a tire bladder grinding device. Background Technology

[0002] A tire bladder is an inner mold used in tire vulcanization molding. During tire manufacturing, the tire bladder is installed into the tire blank, and then compressed gas is filled into the tire bladder to expand it, supporting the unvulcanized tire blank and making the tire blank fit tightly against the inner wall of the molding die to form a preset shape and size, thereby ensuring the dimensional accuracy of the tire.

[0003] Tire bladders are formed by extrusion using upper and lower molds during production. The gap between the upper and lower molds leaves annular flash on the outer surface of the tire bladder. The outer surface of the tire bladder is related to the appearance of the inner wall of the tire. Therefore, the flash needs to be removed and polished during tire bladder manufacturing. In the existing technology, flash removal is often done manually. However, manual polishing often results in an uneven outer surface and irregular shape of the tire bladder, leading to uneven thickness of the tire blank during molding and affecting the safety and appearance quality of the product. Utility Model Content

[0005] To solve the above-mentioned technical problems, one embodiment of this utility model adopts the following technical solution:

[0006] A tire bladder grinding device includes a support frame, a rotating assembly, and a flexible grinding assembly. The rotating assembly is installed in the middle of the support frame, and the flexible grinding assembly is installed on one side of the rotating assembly.

[0009] Optionally, a buffer is also fixedly installed on the upper end of the third cylinder, and the working end of the buffer corresponds to the position of the second limiting plate.

[0010] Optionally: The rotating assembly includes a motor, a gearbox, a drive wheel, and a driven wheel. The motor and gearbox are horizontally fixed on the support frame. The output shaft of the motor is connected to the input end of the gearbox. The output end of the gearbox is fixedly connected to one side of the drive wheel through a transmission shaft. The driven wheel is located on the opposite side of the drive wheel and is rotatably connected to the cylinder shaft of the first cylinder. The first cylinder is fixedly mounted on the support frame, and its cylinder shaft is concentric with the transmission shaft. A capsule clamping space is maintained between the drive wheel and the driven wheel.

[0011] Optional: The rotating assembly further includes a rotary joint, which is mounted on the drive shaft.

The rotary joint is connected to an external air source.

[0012] Optionally, the driving wheel and the driven wheel are frustums of the same shape, with their small end faces facing each other. The frustum has two circular end faces with unequal diameters, with the smaller diameter end face being the smaller end face.

[0013] Optionally, a bridge bearing is also fixedly installed between the gearbox and the drive wheel on the drive shaft.

[0014] Optional: It also includes a lifting assembly, which includes a second cylinder and a U-shaped bracket.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0023] like Figure 1As shown, a tire bladder grinding device includes: a support frame 1, a lifting assembly 2, a rotating assembly 3, and a flexible grinding assembly 4. The support frame 1 is a frame structure. The rotating assembly 3 is installed in the middle of the support frame 1, the lifting assembly 2 is installed at the bottom of the rotating assembly 3, and the flexible grinding assembly 4 is installed on one side of the rotating assembly 3. The lifting assembly 2 lifts the tire bladder 5 between the rotating assembly 3 and the tire bladder 5. The rotating assembly 3 clamps and fixes the tire bladder 5, then inflates it to make the tire bladder 5 fully inflated, and finally rotates the tire bladder 5. The flexible grinding assembly 4 grinds the burrs on the outer wall of the tire bladder 5.

[0024] like Figure 1 , Figure 2 The rotating assembly 3 shown includes: a motor 301, a gearbox 302, a drive wheel 303, and a driven wheel 304. The motor 301 and gearbox 302 are horizontally fixed on the support frame 1. The output shaft of the motor 301 is connected to the input end of the gearbox 302. The output end of the gearbox 302 is fixedly connected to one side of the drive wheel 303 through a transmission shaft 305. The motor 301 drives the gear of the gearbox 302 to rotate, and the gearbox 302 performs speed conversion to drive the transmission shaft 305 and the drive wheel 303 to rotate. Driven wheel 304 is located on the opposite side of drive wheel 303 and is rotatably connected to the cylinder shaft of first cylinder 306. First cylinder 306 is fixedly mounted on support frame 1, and its cylinder shaft is concentric with drive shaft 305. By keeping the cylinder shaft and drive shaft 305 concentric, drive wheel 303 and driven wheel 304 are kept concentric. A capsule clamping space 307 is maintained between drive wheel 303 and driven wheel 304, which facilitates the loading and unloading of tire capsules 5. Rotating assembly 3 also includes a rotary joint 309 for rotating... The connector 309 is mounted on the drive shaft 305, which has a vent hole (not shown in the figure). One end of the vent hole is connected to the rotary connector 309, and the other end is connected to the capsule clamping space 307. The rotary connector 309 is connected to an external air source. In use: the lifting assembly 2 lifts the tire capsule 5 into the capsule clamping space 307, the cylinder shaft of the first cylinder 306 extends, driving the driven wheel 304 to move towards the driving wheel 303, until the driving wheel 303 and the driven wheel 304 clamp and seal both ends of the tire capsule 5. The drive wheel 303 and the driven wheel 304 seal the openings at both ends of the tire capsule 5 and perform compression and sealing clamping. After the driven wheel 304 moves to the predetermined position, the first cylinder 306 stops moving. An external air source inflates the tire capsule 5 quantitatively through the rotary joint 309. After inflation, the motor 301 drives the drive wheel 303 to rotate, and the drive wheel 303 drives the tire capsule 5 to rotate. The driven wheel 304 follows the rotation of the tire capsule 5, and the flexible grinding component 4 grinds the burrs on the outer wall of the tire capsule 5.

[0025] A bridge bearing 308 is also fixedly installed between the gearbox 302 and the drive wheel 303 on the drive shaft 305. The bridge bearing 308 is fixedly connected to the support frame 1. The bridge bearing 308 makes the drive shaft 305 run more smoothly, thereby ensuring that the drive wheel 303 and the driven wheel 304 are concentric.

[0026] The driving wheel 303 and the driven wheel 304 are truncated cones of the same shape, and the small end faces of the driving wheel 303 and the driven wheel 304 are arranged facing each other. The driving wheel 303 and the driven wheel 304 of the truncated cone can keep the tire capsule 5 concentric with the driving wheel 303 and the driven wheel 304, and keep the tire capsule 5 in a horizontal state to prevent the tire capsule 5 from shifting and producing unqualified products.

[0027] like Figure 1 , Figure 3 As shown: The lifting assembly 2 includes a vertical guide rail 201, a second cylinder 202, a U-shaped bracket 203, and a height adjusting rod 204. The vertical guide rail 201 is vertically fixedly installed on the support frame 1 below the rotating assembly 3. The second cylinder 202 is slidably connected to the vertical guide rail 201, with its cylinder axis pointing upwards and fixedly connected to the bottom of the U-shaped bracket 203. The upper end of the height adjusting rod 204 is rotatably connected to the bottom of the second cylinder 202. An adjusting rod limiting nut 205 is also threaded onto the height adjusting rod 204, and the adjusting rod limiting nut 205 is fixedly connected to one side of the vertical guide rail 201. The U-shaped bracket 203 is a semi-circular bracket with its arc-shaped opening facing upwards and directly opposite the capsule clamping space 307. Before grinding the tire capsule 5... The height adjustment lever 204 is rotated to adjust the height position of the second cylinder 202, compensating for the movement distance of the cylinder shaft of the second cylinder 202 to accommodate tire capsules of different diameters. After the height of the second cylinder 202 is adjusted, the tire capsule 5 is placed on the U-shaped bracket 203. Then, the cylinder shaft of the second cylinder 202 extends to lift the tire capsule 5 until its two ends are concentric with the driving wheel 303 and the driven wheel 304. The second cylinder 202 stops moving, and the driving wheel 303 and the driven wheel 304 clamp the tire capsule 5. After clamping, the cylinder shaft of the second cylinder 202 retracts. After grinding is completed, it is raised again to lift the tire capsule 5. The lifting assembly 2 completes the loading and unloading of the tire capsule 5, avoiding heavy labor.

[0028] like Figure 1 , Figure 4As shown: The flexible grinding assembly 4 includes a guide rail 401, a grinding machine clamping assembly, and a grinding machine 402. The guide rail 401 is vertically fixed on the support frame 1. A slider 403 is slidably sleeved on the guide rail 401. A mounting base 404 is fixedly connected to one side of the slider 403. The mounting base 404 has a mounting shaft 405, which is perpendicular to the guide rail 401. The mounting base 404 can slide up and down on the guide rail 401 via the slider 403. The grinding machine clamping assembly is mounted on the mounting shaft 405 and specifically includes a rotating plate 406, a driven plate 407, and a first spring 408. The rotating plate 406 is sleeved on the mounting shaft 405 and can swing left and right at a small angle. The first spring 408 is sleeved on the mounting shaft 405 and located between the rotating plate 406 and the mounting base 404. The rotating plate 406 is threaded onto the mounting shaft. The limiting nut 409 on 405 provides a limit. The upper and lower ends of the driven plate 407 and the rotating plate 406 are connected by bolts. The clamping end of the grinder 402 is clamped and fixed by the driven plate 407 and the rotating plate 406, so that the working end of the grinder 402 can fit in contact with the tire bladder 5. In use: the height of the grinder 402 can be adjusted by adjusting the height of the mounting base 404. The axial position of the driven plate 407 on the mounting shaft 405 can be changed by changing the limiting nut 409, thereby adjusting the axial position of the grinder 402 on the mounting shaft 405. The first spring 408 provides elastic support to the rear of the rotating plate 406 to prevent the rotating plate 406 from being rigidly connected to the mounting shaft 405. The grinding angle of the working end of the grinder 402 can also be adjusted by the rotating plate 406 and the driven plate 407.

[0029] The flexible grinding assembly 4 also includes a flexible limiting assembly, which includes a connecting block 410. One end of the connecting block 410 is fixedly connected to the mounting base 404, and the other end of the connecting block 410 is threadedly connected to an adjusting nut 411. A second spring 412 is fixedly connected to the lower end of the adjusting nut 411. A first limiting plate 413 is also fixedly connected to one side of the rotating plate 406. The upper surface of the first limiting plate 413 corresponds to the lower end of the second spring 412. During use, as the grinding machine 402 contacts the outer surface of the tire bladder 5, the burrs will cause the grinding machine 402 to bounce up and down. To make the grinding smoother, additional... The flexible limiting component rotates the rotating plate 406 and the first limiting plate 413 left and right as the grinding machine 402 bounces during grinding. As the first limiting plate 413 rotates left and right, it compresses the second spring 412. The second spring 412 ensures that the grinding machine 402 does not bounce too much up and down, and also prevents the grinding machine 402 from making hard contact with the outer surface of the tire capsule 5. In order to adjust the swing distance of the grinding machine 402, when the swing of the grinding machine 402 is large, the limiting distance of the second spring 412 can be adjusted by rotating the adjusting nut 411 to reduce the swing of the grinding machine 402.

[0030] The flexible polishing assembly 4 also includes a third cylinder 414, which is vertically fixedly installed on the lower side of the guide rail 401 on the support frame 1. A second limiting plate 415 is also fixedly installed on the lower part of the slider 403 of the guide rail 401. The second limiting plate 415 corresponds to the cylinder shaft of the third cylinder 414, and is in contact but not fixedly connected. Before polishing, the cylinder shaft of the third cylinder 414 extends and lifts the flexible polishing assembly 4 through the second limiting plate 415, so that the polishing machine 402 is away from the capsule clamping space 307. After the tire capsule 5 is clamped, fixed and rotated, the polishing machine 402 is started, the cylinder shaft of the third cylinder 414 is retracted, and the flexible polishing assembly 4 slides down with the guide rail 401 under the action of gravity. The working part of the polishing machine 402 contacts the outer surface of the tire capsule and polishes the burrs.

[0031] A buffer 416 is also fixedly installed on the upper end of the third cylinder 414. The upper working end of the buffer 416 corresponds to the position of the second limiting plate 415, and is in contact but not fixedly connected. During the downward sliding process of the flexible grinding component 4, the flexible grinding component 4 has a downward impact force, which can easily cause over-grinding of the tire capsule 5, making the tire capsule 5 uneven. The buffer 416 effectively avoids the downward impact force of the flexible grinding component 4, so that the grinding machine 402 makes flexible contact with the outer surface of the tire capsule 5.

[0032] Specific usage method: Before first use, the height of the lifting component 2 needs to be adjusted according to the size of the tire capsule 5, as follows: According to the size of the tire capsule 5, rotate the height adjustment rod 204 forward or backward to make the second cylinder 202 move up or down. When the cylinder shaft of the second cylinder 202 extends, it can lift the tire capsule 5 into the capsule clamping space 307 and keep it concentric with the driving wheel 303 and the driven wheel 304. The height adjustment of the lifting component 2 is completed.

[0033] After the height adjustment is completed, the tire capsule 5 can be ground, specifically as follows: Place the blank tire capsule on the U-shaped bracket 203, then extend the cylinder shaft of the second cylinder 202 to lift the tire capsule 5 until its two ends are concentric with the driving wheel 303 and the driven wheel 304. The second cylinder 202 stops moving, and the cylinder shaft of the first cylinder 306 extends, driving the driven wheel 304 to move towards the driving wheel 303 until the driving wheel 303 and the driven wheel 304 clamp and seal the two ends of the tire capsule 5. An external air source inflates the tire capsule 5 quantitatively through the rotary joint 309. After inflation, the cylinder shaft of the third cylinder 414 retracts, and the flexible grinding component 4 slides downward with the guide rail 401 under the action of gravity. The second cylinder 202 drives the U-shaped bracket 203 to move downward, and at the same time, the grinding machine 402 and the electric... The motor 301 and the grinding machine 402 grind the burrs on the tire capsule 5. During the grinding process, the flexible limiting component flexibly limits the grinding machine until the grinding is completed. After the grinding is completed, the motor 301 and the grinding machine 402 stop. The second cylinder 202 drives the U-shaped bracket 203 to move upward to lift the tire capsule 5. Then, the cylinder shaft of the first cylinder 306 retracts, driving the driven wheel 304 to disengage from the clamp on the tire capsule 5. At the same time, the cylinder shaft of the third cylinder 414 extends, lifting the flexible grinding device, so that the grinding machine 402 disengages from the tire capsule 5. Finally, the cylinder shaft of the second cylinder 202 retracts, driving the finished tire capsule back to the starting point, and the finished product can be removed manually. Repeating the above actions can complete the operation of this utility model. It can quickly grind the tire capsule while ensuring that the ground tire capsule has a flat appearance and a regular shape.

[0034] Although the present invention has been described herein with reference to illustrative embodiments, it should be understood that many other modifications and implementations can be devised by those skilled in the art, which will fall within the scope and spirit of the principles disclosed herein. More specifically, various variations and improvements can be made to the components and / or layout of the subject matter combination within the scope of the present application. Besides variations and improvements to the components and / or layout, other uses will be apparent to those skilled in the art.
