Description

Technical Field

[0001] The utility model relates to the technical field of tire processing equipment, and particularly relates to a tire cutting device. Background Art

[0002] With the gradual improvement of people's living standards, the ownership of private cars and the number of trucks in China have also increased year by year. The increase in the number of vehicles has driven economic development. At the same time, the consumption and wear of automobile tires have generated a large number of waste tires, which need to be processed by equipment such as tire cutting machines before recycling.

[0003] For example, Chinese Patent CN213532731U discloses a cutting device for tire processing, including an equipment box, a column, a mounting plate, a sliding seat, a first motor, a cutting tool mounting bracket, a cutting tool, a second motor, a rack, a turntable, a tire fixing device, a feed handwheel and casters. The bottom end of the column is connected to the top end of the equipment box. A chamber is provided inside the equipment box. The mounting plate is mounted on the column. The sliding seat is slidably connected to the mounting plate. The first motor is mounted on the sliding seat. The cutting tool mounting bracket is mounted on the sliding seat. The output end of the first motor is connected to the input end of the cutting tool mounting bracket. The cutting tool is mounted on the cutting tool mounting bracket and slides relatively. The second motor is mounted on the sliding seat. A gear is provided at the output end of the second motor. The gear is meshed with the rack. The rack is mounted on the mounting plate. During operation, rotate the feed handwheel, the tire fixing device fixes the tire, turn on the third motor, the third motor drives the rotating shaft to rotate through the speed reducer, the rotating shaft drives the turntable to rotate, turn on the second motor, the second motor drives the gear to rotate, and drives the mounting plate to move left and right through the meshing connection between the gear and the rack to determine the cutting position. Then turn on the first motor, and the first motor drives the cutting tool to move up and down through the cutting tool mounting bracket.

[0004] It can be seen that when the existing tire cutting equipment cuts different waste tires, it is necessary to move the position of the cutting device, so as to change the distance between the cutting tool and the waste tire to achieve the effect of cutting waste tires of different sizes. However, the structure of the cutting device is relatively complex, and there are many connecting lines. Frequent movement is likely to cause damage to the cutting device. At the same time, frequent movement of the cutting device will also cause wear of the guide rail of the cutting device, resulting in the cutting tool not being perpendicular, and thus reducing the cutting effect. Summary of the Utility Model

[0005] The object of the present utility model is to solve the problem that in the existing tire cutting device, when cutting different tires, the cutting device needs to be moved, which may easily damage the cutting device and wear the guide rail of the cutting device, resulting in the cutting knife not being perpendicular and reducing the cutting effect. The present utility model provides a tire cutting device, which does not need to move the cutting device when cutting different tires, can effectively avoid damage to the cutting device and wear of the guide rail of the cutting device, ensure the perpendicularity of the cutting knife, and ensure the cutting effect.

[0006] To solve the above technical problems, an embodiment of the present utility model discloses a tire cutting device, including:

[0007] An operating table;

[0008] A placing plate, connected to the operating table in a manner that can move along a first direction;

[0009] A fixing component, rotatably arranged above the placing plate, and the fixing component is used for fixing the tire and driving the tire to rotate;

[0010] A cutting mechanism, including a cutting tool, and the cutting tool is fixed to one end of the operating table along the first direction, and the cutting tool is used for cutting the tire.

[0011] By adopting the above technical solution, the position of the cutting tool relative to the operating table remains fixed, and the placing plate drives the fixing component and the tire to approach or move away from the cutting tool along the first direction. Exemplarily, when the tire size is large, the placing plate is moved along the first direction away from the cutting tool, and when the tire size is small, the placing plate is moved along the first direction towards the cutting tool, so as to adjust the distance between the tire and the cutting tool, enabling the tire cutting device provided by the embodiment of the present application to be applicable to tires of various sizes and effectively improving the applicable range of the tire cutting device. Moreover, in the embodiment of the present application, the distance between the tire and the cutting tool is adjusted by moving the tire, rather than moving the cutting mechanism and the cutting tool, which can effectively extend the service life of the cutting mechanism, ensure the perpendicularity of the cutting tool at the same time, and effectively ensure the cutting effect on the tire.

[0012] According to another specific embodiment of the present utility model, along a second direction, a limiting block is provided at the bottom of the placing plate, and the second direction is perpendicular to the first direction;

[0013] Along the second direction, a limiting groove is provided at the top of the operating table, and the limiting groove extends along the first direction, and the limiting block is connected to the limiting groove in a manner that can slide along the first direction;

[0014] The limiting block and the limiting groove cooperate to form a limit for the placing plate in the second direction.

[0015] With the above technical solution, through the cooperation of the limiting block and the limiting groove, the storage plate is limited in the second direction to prevent the storage plate from detaching from the operating table in the second direction. Moreover, the limiting block can move relative to the limiting groove in the first direction, thereby driving the storage plate, the fixing component, and the tire fixed by the fixing component to move in the first direction to approach or move away from the cutting tool.

[0016] According to another specific embodiment of the present invention, the limiting block includes a first part and a second part;

[0020] At least a part of the first part is located in the limiting groove, and the second part is located below the limiting groove along the second direction to form a limit on the storage plate in the second direction.

[0021] With the above technical solution, along the third direction, the width of the first part is set to be shorter than that of the second part, that is, the cross-sections of the first part and the second part are in a "convex" shape structure. Along the second direction, the storage plate and the second part of the limiting block are respectively located on the upper and lower sides of the limiting groove. As described above, since the width of the second part along the third direction is greater than the width of the limiting groove, the storage plate can be stably connected to the operating table and will not detach from the operating table, ensuring the stability of the tire during the cutting process.

[0022] According to another specific embodiment of the present invention, the number of the limiting grooves is two, and the two limiting grooves are arranged on the operating table at intervals along the third direction, and the third direction is perpendicular to the first direction and the second direction;

[0023] The number of the limiting blocks is two, and the two limiting blocks are arranged on the bottom of the storage plate at intervals along the third direction;

[0041] The guide posts sequentially pass through one of the avoidance grooves and one of the guide grooves along the second direction;

[0042] When the adjusting disk rotates, the guide grooves can drive the guide posts to move relative to the avoidance grooves along the radial direction of the base disk, so that the tensioning plate moves from the first position to the second position, or from the second position to the first position.

[0077] To make the purpose, technical solution and advantages of the present utility model clearer, the following will further describe the embodiments of the present utility model in detail with reference to the drawings.

[0078] Refer to Figure 1 and Figure 2 , an embodiment of the present application provides a tire cutting device for cutting the rims of waste tires. The tire cutting device includes: a mounting assembly 1, an adjusting assembly 2, and a fixing assembly 3. Among them, the adjusting assembly 2 is mounted on the mounting assembly 1, and the fixing assembly 3 is mounted on the adjusting assembly 2.

[0079] Specifically, the mounting assembly 1 includes an operating table 101 and a cutting mechanism 104. The cutting mechanism 104 is fixed to one end of the operating table 101 along the first direction X. The cutting mechanism 104 includes a cutter 1041, and the cutter 1041 is used for cutting the tire. Correspondingly, the cutter 1041 is fixed to one end of the operating table 101 along the first direction X.

[0080] The adjusting assembly 2 includes a placing plate 201. The placing plate 201 is connected to the operating table 101 in a manner that it can move along the first direction X. The fixing assembly 3 is rotatably arranged above the placing plate 201. Among them, the fixing assembly 3 is used for fixing the tire and driving the tire to rotate. Furthermore, the placing plate 201 can drive the fixing assembly 3 and the tire fixed by the fixing assembly 3 to move along the first direction X to approach or move away from the cutter 1041.

[0081] In the embodiment of the present application, the position of the cutting tool 1041 relative to the operating table 101 remains fixed. The placing plate 201 drives the fixing assembly 3 and the tire to approach or move away from the cutting tool 1041 along the first direction X. Exemplarily, when the tire size is large, the placing plate 201 is moved along the first direction X away from the cutting tool 1041. When the tire size is small, the placing plate 201 is moved along the first direction X towards the cutting tool 1041, so as to adjust the distance between the tire and the cutting tool 1041, making the tire cutting ring device provided by the embodiment of the present application applicable to tires of various sizes and effectively improving the applicable range of the tire cutting ring device.

[0082] Moreover, in the embodiment of the present application, the distance between the tire and the cutting tool 1041 is adjusted by moving the tire, without moving the cutting mechanism 104. This can effectively extend the service life of the cutting mechanism 104, while ensuring the perpendicularity of the cutting tool 1041 and effectively guaranteeing the cutting ring effect on the tire.

[0083] In some possible implementation manners, with reference to Figure 3 and in combination with Figure 1 , along the second direction Y (the second direction Y is perpendicular to the first direction X), a limiting block 202 is provided at the bottom of the placing plate 201. Along the second direction Y, a limiting groove 106 is provided at the top of the operating table 101. The limiting groove 106 extends along the first direction X. The limiting block 202 is connected to the limiting groove 106 in a slidable manner along the first direction X. Through the cooperation of the limiting block 202 and the limiting groove 106, the placing plate 201 can move relative to the operating table 101 along the first direction X, and then drive the fixing assembly 3 and the tire fixed by the fixing assembly 3 to move along the first direction X to approach or move away from the cutting tool 1041.

[0084] In some possible implementation manners, continue to refer to Figure 3 and in combination with Figure 1 , the limiting block 202 includes a first part 2021 and a second part 2022. Along the second direction Y, the first part 2021 is located between the second part 2022 and the placing plate 201.

[0085] Wherein, the width of the first part 2021 along the third direction Z (the third direction Z is perpendicular to the first direction X and the second direction Y) is less than or equal to the width of the limiting groove 106 along the third direction Z, and the width of the second part 2022 along the third direction Z is greater than the width of the limiting groove 106 along the third direction Z. That is to say, along the third direction Z, the width of the first part 2021 is shorter than the width of the second part 2022, that is, the cross sections of the first part 2021 and the second part 2022 are in a "convex" shape structure.

[0086] Further, at least a part (i.e., all or part) of the first part 2021 is located within the limiting groove 106, and the second part 2022 is located below the limiting groove 106 along the second direction Y. That is, along the second direction Y, the storage plate 201 and the second part 2022 of the limiting block 202 are respectively located on the upper and lower sides of the limiting groove 106. As mentioned above, the width of the second part 2022 along the third direction Z is greater than the width of the limiting groove 106.

[0087] That is to say, through the cooperation of the limiting block 202 and the limiting groove 106, a limit on the storage plate 201 along the second direction Y is formed, preventing the storage plate 201 from detaching from the operating table 101 along the second direction Y. Therefore, the storage plate 201 can be stably connected to the operating table 101 without detaching from the operating table, ensuring the stability during the tire cutting process. Moreover, the limiting block 202 can move relative to the limiting groove 106 along the first direction X, thereby driving the storage plate 201, the fixing component 3, and the tire fixed by the fixing component 3 to move along the first direction X to approach or move away from the cutter 1041.

[0088] Exemplarily, in the embodiment of the present application, the number of the limiting grooves 106 is two, and the two limiting grooves 106 are arranged on the operating table 101 at intervals along the third direction Z. Correspondingly, the number of the limiting blocks 202 is two, and the two limiting blocks 202 are arranged at intervals along the third direction Z at the bottom of the storage plate 201. Each limiting block 202 is connected to a limiting groove 106 in a slidable manner along the first direction X. By providing two limiting grooves 106 and providing limiting blocks 202 that cooperate with the two limiting grooves 106 one by one, the stability of the storage plate 201 when moving along the first direction X can be effectively improved. Regarding the number of the limiting grooves 106 and the limiting blocks 202, the embodiment of the present application does not make specific limitations. For example, one, three, four, five or more limiting grooves 106 can also be provided, and limiting blocks 202 corresponding to the number of the limiting grooves 106 are provided, as long as it can ensure that the storage plate 201 can move relative to the operating table 101 along the first direction X.

[0089] In some possible implementation manners, continue to refer to Figure 3 , a fixing bolt 205 is further provided at the edge of the storage plate 201. After the storage plate 201 moves to the target position (i.e., the cutting position) relative to the operating table 101 along the first direction X, the relative position of the storage plate 201 and the operating disk 101 can be fixed through the fixing bolt 205, preventing the storage plate 201 from moving relative to the operating table 101 during the cutting process.

[0090] The specific structure of the fixing component 3 will be introduced in detail below with reference to the drawings.

[0091] Refer to Figure 4 and in combination with Figure 1The fixing assembly 3 of the embodiment of the present application includes: a base plate 301 and a plurality of tensioning plates 305 .

[0092] Specifically, the base plate 301 is rotatably connected to the upper portion of the storage plate 201 along the second direction Y. Each of the plurality of tension plates 305 is connected to the base plate 301 in a manner of being movable along a radial direction U of the base plate 301 .

[0093] For example, reference Figure 3 Combined with Figure 1 and Figure 4 , a motor seat 203 is provided at the bottom of the storage plate 201, and a first motor 204 is installed on the motor seat 203. The output shaft of the first motor 204 (not shown) extends along the second direction Y and passes through the storage plate 201. At the same time, the output shaft of the first motor 204 is fixedly connected to the base plate 301, so that the output shaft of the first motor 204 drives the base plate 301 to rotate, and then the base plate 301 can drive the tire to rotate to cut the tire. Exemplarily, the first motor 204 is located at the bottom center of the storage plate 201 along the second direction Y, and the output shaft of the first motor 204 is fixedly connected to the bottom center of the base plate 301.

[0094] Correspondingly, the operating table 101 is provided with a long slot 105, which extends along the first direction X. At least a portion of the motor seat 203 and at least a portion of the first motor 204 are located in the long slot 105 and can move relative to the long slot 105 along the first direction X. That is, along the second direction Y, the long slot 105 avoids the motor seat 203 and the first motor 204 to ensure that the cooperation between the limit block 202 and the limit slot 106 described above is not affected.

[0095] By way of example, in the embodiment of the present application, the motor seat 203 includes two first connecting plates 2031 and a first supporting plate 2032, wherein the two first connecting plates 2031 are arranged at intervals along the first direction X, one end of one of the first connecting plates 2031 is fixed to the bottom of the storage plate 201, and the other end is connected to one end of the first supporting plate 2032, one end of the other first connecting plate 2031 is fixed to the bottom of the storage plate 201, and the other end is connected to the other end of the first supporting plate 2032, and the first motor 204 is mounted on the first supporting plate 2032. The embodiment of the present application does not specifically limit the connection method between the first supporting plate 2032 and the first connecting plate 2031. By way of example, in the embodiment of the present application, the first supporting plate 2032 and the first connecting plate 2031 are integrally formed. In other embodiments, the first supporting plate 2032 and the first connecting plate 2031 may be fixedly connected by welding, bolts, screws, etc.

[0096] The present application embodiment does not specifically limit the fixing manner of the motor base 203 and the placement plate 201. For example, it can be fixed by welding, bolts, screws, etc.

[0097] In some possible implementation manners, each tension plate 305 is arc-shaped and extends along the circumferential direction of the base disk 301. A plurality of tension plates 305 surround the base disk 301 along the circumferential direction R of the base disk 301.

[0098] Wherein, each tension plate 305 has a first position (a position close to the base disk 301 along the radial direction U, as shown by the tension plate 305 in Figure 5 ), and a second position (a position far from the base disk 301 along the radial direction U, as shown by the tension plate 305 in Figure 6 ). Each tension plate 305 can move along the radial direction U of the base disk 301 to the first position or the second position. In the first position, the tension plate 305 does not abut against the tire 4. In the second position, the tension plate 305 abuts against the tire 4. That is, a plurality of tension plates 305 jointly abut against the tire in the second position to clamp the tire 4, so that the base disk 301 can drive the tire to rotate to cut the tire.

[0099] Specifically, referring to Figure 6 and combining with Figure 4 , a plurality of tension plates 305 jointly abut against the inner ring 41 of the tire 4 and provide a pressure along the radial direction U towards the outside of the tire 4 to the inner ring 41 of the tire 4, so as to clamp the tire 4, so that the base disk 301 can drive the tire 4 to rotate to cut the tire 4.

[0100] Exemplarily, continuing to refer to Figure 4 , in the first position, each tension plate 305 is connected end to end along the circumferential direction R of the base disk 301 to form a ring (as shown by the tension plates 305a and 305b in Figure 4 and a plurality of tension plates 305 in Figure 5 ). In the second position, each tension plate 305 is arranged at intervals along the circumferential direction R of the base disk 301 (as shown by a plurality of tension plates 305 in Figure 6 ). However, it is not limited thereto. In some other possible embodiments, in the first position, each tension plate 305 is arranged at intervals along the circumferential direction R of the base disk 301.

[0101] In some possible implementation manners, continuing to refer to Figure 4, on the inner wall of each tension plate 305, there is a sliding block 303 which extends radially U along the base plate 301. The base plate 301 is provided with a plurality of sliding grooves 302 corresponding one-to-one to the number of tension plates 305. Each sliding groove 302 extends radially along the base plate 301 and penetrates the outer side wall 3011 of the base plate 301. Each sliding block 303 is connected to a sliding groove 302 in a radially U-slidable manner along the base plate 301, so that the tension plate 305 can move from the first position to the second position, or from the second position to the first position.

[0102] Exemplarily, along the second direction Y, above each sliding groove 302, there is an avoidance groove 312. Each avoidance groove 312 extends radially U along the base plate 301 and penetrates the outer side wall 3011 of the base plate 301. Along the second direction Y, each sliding groove 302 communicates with the avoidance groove 312 above it. Along the circumferential direction R of the base plate 301, the width of the avoidance groove 312 is smaller than the width of the sliding groove 302, that is, the cross-section of the avoidance groove 312 and the sliding groove 302 is in a "convex" shape.

[0103] Exemplarily, along the second direction Y, above each sliding block 303, there is a guide post 304. Along the second direction Y, the guide post 304 passes through the corresponding avoidance groove 312.

[0104] Exemplarily, along the second direction Y, above the base plate 301, there is an adjusting plate 311. The adjusting plate 311 is rotatably connected to the base plate 301. The adjusting plate 311 is provided with a plurality of guide grooves 308 corresponding one-to-one to the number of guide posts 304. The extending direction of each guide groove 308 is not perpendicular to the radial U of the base plate 301. That is, in the projection along the second direction Y, each guide groove 308 and the corresponding sliding groove 302 are arranged at an angle, and this angle is not 90°. The guide post 304 passes through an avoidance groove 312 and a guide groove 308 in sequence along the second direction Y.

[0105] Specifically, when the adjusting plate 311 rotates relative to the base plate 301, the guide groove 308 can exert a squeezing effect on the part of the guide post 304 located in the guide groove 308, thereby driving the guide post 304 to move radially U relative to the avoidance groove 312 along the base plate 301, and further driving the sliding block 303 and the tension plate 305 fixed to the sliding block 303 to move radially U along the base plate 301, so that the tension plate 305 can move from the first position to the second position, or from the second position to the first position.

[0106] For example, when a tire needs to be cut, the tire is placed on the storage plate 201, and the adjustment disc 311 is controlled to rotate forward so that the tension plate 305 moves from the first position to the second position to fix the tire. Then, the base disc 301 drives the tire to rotate for cutting. When the tire needs to be replaced or the work needs to be stopped after cutting, the adjustment disc 311 is controlled to rotate reversely so that the tension plate 305 moves from the second position to the first position, facilitating tire replacement or stopping the work. It should be noted that the present application embodiment does not specifically limit the forward rotation and reverse rotation. For example, the forward rotation can be clockwise rotation or counterclockwise rotation, and the reverse rotation has a rotation direction opposite to that of the forward rotation. As long as the tension plate 305 can move from the first position to the second position during forward rotation and the tension plate 305 can move from the second position to the first position during reverse rotation.

[0107] In addition, through the movement of the plurality of tension plates 305 between the first position and the second position, the fixing component 3 in the embodiment of the present application can be applied to tires of various sizes, improving the applicability of the tire cutting device in the embodiment of the present application. Specifically, there are multiple second positions, and each second position corresponds to a tire of a different size. Refer to Figure 5 and Figure 6 and in combination with Figure 4 , exemplarily, when the inner diameter of the inner ring 41 of the tire 4 is relatively large, the adjustment disc 311 drives the tension plate 305 to move a first distance along the radial direction U to abut against the inner ring 41 (i.e., one of the second positions), thereby achieving the fixation of the tire 4. When the inner diameter of the inner ring 41 of the tire 4 is relatively small, the adjustment disc 311 drives the tension plate 305 to move a second distance along the radial direction U to abut against the inner ring 41 (i.e., another second position), thereby achieving the fixation of the tire 4. Among them, the first distance is greater than the second distance.

[0108] In some possible implementation manners, the fixing component 3 further includes a rotating block 309. Correspondingly, along the second direction Y, a rotating groove 310 is formed at the top of the base disc 301, and the rotating groove 310 extends along the second direction Y. The rotating block 309 extends along the second direction Y, and the rotating block 309 is rotatably connected to the rotating groove 310. Along the second direction Y, the top end of the rotating block 309 is fixedly connected to the bottom of the adjustment disc 311. Exemplarily, the rotating block 309 is cylindrical. The function of the rotating block 309 is to support the adjustment disc 311 to keep the rotation of the adjustment disc 311 stable.

[0109] Exemplarily, the fixing component 3 further includes a motor bracket 306 and a second motor 307. The motor bracket 306 is fixed to the top of the base plate 301 along the second direction Y.

Exemplarily, the output shaft of the second motor 307 is connected to the central position of the top of the adjustment plate 311 along the second direction Y.

[0112] Specifically, referring to Figure 1 and Figure 2 , the lifting component 1042 includes a lifting cylinder 10421, a lifting rod 10422, a lifting plate 10423, a guiding column 10424 and a bracket 10425. Among them, the lifting cylinder 10421 extends along the second direction Y, and the lifting cylinder 10421 is fixed to one end of the operating table 101 along the first direction X.

[0113] Exemplarily, the lifting rod 10422 extends along the second direction Y, and the lifting rod 10422 is sleeved in the lifting cylinder 10421 in a manner that is movable along the second direction Y. One end of the lifting rod 10422 away from the lifting cylinder 10421 is fixed with a lifting plate 10423. The lifting plate 10423 extends along the third direction Z. Along the third direction Z, a guiding hole (not shown in the figure) is provided at each end of the lifting plate 10423. The guiding column 10424 extends along the second direction Y, and each guiding column 10424 passes through a guiding hole of the lifting plate 10423. The guiding column 10424 can guide the lifting plate 10423 to move along the second direction Y.

[0114] Exemplarily, the bracket 10425 and the lifting cylinder 10421 are fixed to the same end of the operating table 101 along the first direction X. Along the second direction Y, one end of the guiding column 10424 is fixed to the operating table 101, and the other end is fixed to the bracket 10425. That is, the bracket 10425 and the operating table 101 jointly fix the guiding column 10424.

[0115] Along the first direction X, on the side of the lifting plate 10423 close to the placing plate 2, there is a fixing plate 10426 which extends along the first direction X. Along the first direction X, one end of the fixing plate 10426 is connected to the lifting plate 10423, and the other end is fixed with the cutter 1041. For the connection manner between the lifting plate 10423 and the fixing plate 10426, the embodiments of the present application do not make specific limitations. Exemplarily, in the embodiments of the present application, the fixing plate 10426 and the lifting plate 10423 are integrally formed. In other embodiments, the fixing plate 10426 and the lifting plate 10423 can be fixedly connected by welding, bolts, screws, etc.

[0116] For the specific lifting manner of the lifting rod 10422, the embodiments of the present application do not make specific limitations, as long as the lifting rod 10422 can drive the lifting plate 10423 and the cutter 1041 to lift along the second direction Y. For example, the lifting of the lifting rod 10422 can be realized by a cylinder.

[0117] In some possible implementation manners, referring to Figure 1 and Figure 2 , the mounting assembly 1 further includes a bottom plate 107 and a damper 102, which are arranged below the operating table 101 along the second direction Y. Along the second direction Y, one end of the damper 102 is fixed to the bottom plate 107, and the other end is fixed to the operating table 101. The damper 102 can buffer and absorb the vibration generated when the tire cutting ring device works, thereby reducing the damage to the electrical equipment caused by high-frequency vibration and improving the service life of the tire cutting ring device.

[0118] In some possible implementation manners, continuing to refer to Figure 1 and Figure 2 , each damper 102 is sleeved with a damping spring 103. Along the second direction Y, one end of the damping spring 103 abuts against the bottom plate 107, and the other end abuts against the operating table 101. The damping spring 103 can improve the buffer absorption effect on the vibration generated when the tire cutting ring device works, further reducing the damage to the electrical equipment caused by high-frequency vibration and improving the service life of the tire cutting ring device.

[0119] In some possible implementation manners, continuing to refer to Figure 1 and Figure 2, in the embodiment of the present application, the operation table 101 has a generally rectangular structure, and a damper 102 is provided at the bottom of each of the four corners of the operation table 101. To improve the buffering and absorption effect of the vibration generated during the operation of the tire cutting device, further reduce the damage to electrical equipment caused by high-frequency vibration, and improve the service life of the tire cutting device.

[0120] Regarding the specific number of the dampers 102 and the damper springs 103 sleeved on the dampers 102, the embodiment of the present application does not make specific limitations, as long as it can play a role in buffering and absorbing the vibration generated during the operation of the tire cutting device, reduce the damage to electrical equipment caused by high-frequency vibration, and improve the service life of the tire cutting device. For example, five, six or seven or more dampers 102 and damper springs 103 corresponding to the number of dampers 102 one by one can be set.

[0121] Reference Figures 1 to 5 , in the tire cutting device in the embodiment of the present application, before working, first place the tire 4 to be cut on the placing plate 201, and make the fixing component 3 located in the inner circle 41 of the tire 4. Then start the second motor 307 to drive the adjusting disc 311 to rotate relative to the base disc 301, so that a plurality of tension plates 305 move from the first position to the second position to clamp the tire 4. Then, move the placing plate 201 relative to the operation table 101 along the first direction X to the target position, and fix the position of the placing plate 201 relative to the operation table 101 through the fixing bolt 205. Then drive the cutter 1041 to move to the cutting position through the lifting component 1042 of the cutting mechanism 104, and start the first motor 204 to drive the base disc 301 to rotate to drive the tire 4 to rotate, so as to realize cutting the tire 4.

[0122] In the above process, only by moving the position of the tire 4 to adjust the distance between the tire and the cutter 1041 along the first direction X, without moving the cutter 1041, so the service life of the cutting mechanism 104 can be effectively improved, and at the same time, the perpendicularity of the cutter 1041 can be ensured, which can effectively ensure the cutting effect of the tire 4.
