Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0028] Example 1

[0029] In this embodiment, as Figures 1-5As shown, a tire-removing device includes a base 101, on which a support column 102 and a fixing column 103 are fixedly installed for support. A tire-removing mechanism 200 is provided on the top of the support column 102, and a limiting mechanism 300 is provided on one side of the fixing column 103. A tire blank 104 is provided on the limiting mechanism 300. Before the tire-removing device is used, it is first checked whether the device can be used normally, and then the limiting mechanism 300 is used to adjust the device to put it into the ready-to-use state.

[0030] The tire-changing mechanism 200 includes a slide plate 201. A clamping assembly for clamping the tire blank 104 head is slidably mounted on the upper surface of the slide plate 201. A slider 202 is fixedly mounted on the lower surface of the slide plate 201. The slider 202 is slidably connected to the support column 102. The shape of the support column 102 matches the shape of the slide plate 201. A mounting plate 203 is fixedly mounted on the end of the slide plate 201 away from the fixed column 103. An adjusting screw 204 is threadedly connected to the bottom of the mounting plate 203. One end of the adjusting screw 204 is rotatably connected to the support column 102, and the other end of the adjusting screw 204 is fixed. A throttle handle is provided. Turning the throttle handle will drive the adjusting screw 204 to rotate, so that the slide plate 201 can move along the direction of the slider 202, thereby adjusting the distance between the slide plate 201 and the tire blank 104, thus ensuring that the clamping plate 207 and the tire blank 104 maintain a reasonable distance. The top of the mounting plate 203 is hinged with a telescopic cylinder 205. The output end of the telescopic cylinder 205 is connected to the clamping assembly. When the telescopic cylinder 205 is activated, it will provide a pulling force to the clamping plate 207 to move to one side of the mounting plate 203, helping the component to separate from the tire blank 104.

[0031] Among them, such as Figures 2-5 As shown, the clamping assembly includes an L-shaped movable plate 206. The output end of a telescopic cylinder 205 is hinged to the L-shaped movable plate 206. A clamping plate 207 is rotatably mounted on the side of the L-shaped movable plate 206 away from the telescopic cylinder 205. The clamping plate 207 moves along the slide plate 201. Several clamping teeth are fixedly mounted on the lower surface of the clamping plate 207. The outer side of the clamping teeth is covered with a rubber or polyurethane protective layer, which increases friction while avoiding damage to the tire blank. A clamping plate cylinder 208 is hinged to the top of the L-shaped movable plate 206. The opening and closing degree of the clamping plate 207 is controlled by the clamping plate cylinder 208. The output end of the clamping plate cylinder 208 is hinged to the clamping plate 207. In use, a part of the material head is placed between the clamping plate 207 and the L-shaped movable plate 206, and the clamping plate cylinder 208 is driven to clamp the material head.

[0032] Among them, such as Figures 2-5As shown, the limiting mechanism 300 includes symmetrically arranged adjusting screws 301. Each adjusting screw 301 is threaded with a support rod seat 302. A crank 303 is fixedly installed on one side of each support rod seat 302. Several movable seats 304 are evenly distributed on the outer side of each support rod seat 302. A support rod 305 is rotatably mounted on each movable seat 304. A clamp 306 for fixing the tire blank 104 is provided at the end of each support rod 305. A sliding rod is fixedly installed at the end of each of the two adjusting screws 301 on opposite sides. 307. Each slide rod 307 has a baffle 308 fixedly installed on the side near the adjusting screw 301. The baffle 308 is stationary. When the support rod seat 302 is cranked by the crank handle 303, the support rod 305 will open under the action of the baffle 308. At the same time, the clamping plate 306 will support the bead portion of the tire blank 104. A sleeve 309 is provided between the two slide rods 307. The sleeve 309 is sleeved on the outside of the slide rod 307 by several bolts to facilitate the adaptation to the bead portion of different tire blanks. The sleeve 309 is a hollow iron tube to preserve the original shape of the tire blank to the greatest extent. The slide rod 307 is slidably connected to the sleeve 309, so that the adjusting screws 301 on both sides are coaxial. A rotating ring 310 is provided on the outer side of the slide rod 307. A tension spring 311 is fixed between the rotating ring 310 and the support rod 305. The tension spring 311 with appropriate tension is selected according to the actual environment. The tension spring 311 provides a force to the support rod 305 to move towards the rotating ring 310, which in turn works with the baffle 308 to limit the opening angle of the support rod 305. To increase the stability, a telescopic guide rod can be provided between the rotating ring 310 and the support rod 305. The tension spring 311 is sleeved on the outer side of the telescopic guide rod to limit its radial swing, ensure that the support rod 305 opens stably, and avoid the tension spring 311 from twisting or tangling when rotating. One side of one of the adjusting screws 301 is provided with a rotating component for rotating the tire blank 104 to assist the tire removal mechanism 200 in achieving the tire removal effect.

[0033] Among them, such as Figure 4 As shown, the clamp 306 includes a clamp mother part 3061 fixedly connected to the support rod 305. A clamp daughter part 3062 is provided on one side of the clamp mother part 3061. The clamp mother part 3061 and the clamp daughter part 3062 are connected by clamp screws. After the support rod 305 is adjusted to a suitable position, the beak part of the tire blank 104 is placed between the clamp mother part 3061 and the clamp daughter part 3062, and the clamp screws are tightened to fix the position of the tire blank 104.

[0034] Among them, such as Figure 3As shown, the rotating assembly includes a motor reduction gearbox 312 and a drive motor 313. The motor reduction gearbox 312 contains components such as belts and gears, which is existing technology. It can adjust the speed and torque of the drive motor 313 so that the device can operate in the best working condition. The motor reduction gearbox 312 is fixedly mounted on the fixed column 103. The output end of the drive motor 313 is fixedly connected to the input end of the motor reduction gearbox 312. A brake component can be provided on one side of the drive motor 313 so that the brake automatically releases when the drive motor 313 is energized and immediately re-engages when the drive motor 313 is de-energized. To prevent accidental rotation of the device, the output end of the motor reducer 312 is coaxially connected to the corresponding adjusting screw 301 via a coupling, facilitating power transmission. After the drive motor 313 starts, the motor reducer 312 adjusts the speed and torque input to the drive motor 313 according to its own transmission ratio, and then outputs the adjusted power from the output end to drive the adjusting screw 301. A foot pedal can be provided on one side of the base 101, which is electrically connected to the drive motor 313 to facilitate the forward and reverse operation of the limit mechanism 300.

[0035] Among them, such as Figure 1 and Figure 2 As shown, a controller 105 is provided on one side of the support column 102. The controller 105 is electrically connected to the electrical components of the device, which facilitates the output of commands and ensures process automation.

[0036] Among them, such as Figure 2 As shown, the adjusting screw 204 is set parallel to the inclined surface of the slide plate 201, and the sliding path of the slide plate 201 and the slider 202 is parallel to the adjusting screw 204, so that when the throttle is turned, the slide plate 201 and the slider 202 can be smoothly driven to move along the surface of the support column 102, ensuring the normal operation of the device.

[0037] Example 2

[0038] The difference from Example 1 is that, as in Example 1, Figure 6 and Figure 7 As shown, the limiting mechanism 300 also includes a limiting ring rotatably disposed on the outside of the slide rod 307. Several connecting blocks 314 are evenly distributed on the outside of the limiting ring. A moving rod 315 is fixedly disposed on the top of the connecting block 314. The moving rod 315 can slide smoothly in the groove 316. The support rod 305 has a groove 316 inside. The moving rod 315 is movably connected to the inner wall of the groove 316. Compared with the baffle 308, the connecting block 314 and the moving rod 315 can make the support rod 305 and the connecting block 314 in a stable connection relationship, which is convenient for limiting the opening degree of the support rod 305.

[0039] In use, first place the tire blank 104 between the clamping plates 306 of the limiting mechanism 300. The clamping plates 306 clamp the bead portion of the tire blank 104. Turn the crank handle 303 to rotate the adjusting screw 301, causing the support rod seat 302 to drive the support rod 305 to expand outward in conjunction with the baffle 308, thereby tightening the bead portion of the tire blank. Adjust the position of the sleeve 309 according to the shape and size of the tire blank 104. Fix the sleeve 309 to the slide rod 307 with bolts to adjust the spacing inside the bead portion of the tire blank, thus completing the adjustment operation of the limiting mechanism 300. Turn the handle of the adjusting screw 204 to drive the sliding plate 201 to slide along the support column 102, so that the clamping plate 207 and the tire... The tire blank 104 is kept at a reasonable distance. At this time, the output end of the telescopic cylinder 205 is in the extended state. The clamping cylinder 208 drives the clamping plate 207 to move downward, so that the part head is restricted between the clamping plate 207 and the L-shaped moving plate 206. The telescopic cylinder 205 drives the L-shaped moving plate 206 to retract, so that the clamping plate 207 moves away from the tire blank 104. The drive motor 313 drives the adjusting screw 301 to rotate through the motor reduction box 312, so that the tire blank 104 rotates slowly. In conjunction with the tire removal mechanism 200, the tire blank head is continuously peeled off. During the tire removal process, a small amount of gasoline or adhesive can be sprayed at the head to improve the peeling effect.

[0040] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
