Detailed implementation manners

[0033] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the drawings and embodiments.

[0034] Embodiment 1

[0035] In this embodiment, as Figures 1-5 shown, a tire demounting device includes a base 101, on which a support column 102 and a fixed column 103 are fixedly installed to play a supporting role. A tire demounting mechanism 200 is arranged at the top of the support column 102, and a limiting mechanism 300 is arranged on one side of the fixed column 103. A tire blank 104 is arranged on the limiting mechanism 300. Before starting to use a tire demounting device, first check whether the device can be used normally, and then adjust it through the limiting mechanism 300 to make the device enter the standby state;

[0036] The tire demounting mechanism 200 includes a sliding plate 201. A clamping component for clamping the head of the tire embryo 104 is slidably arranged on the upper surface of the sliding plate 201. A slider 202 is fixedly installed on the lower surface of the sliding plate 201. The slider 202 is slidably connected to the support column 102. The shape and style of the support column 102 are adapted to the shape and style of the sliding plate 201. One end of the sliding plate 201 away from the fixed column 103 is fixedly provided with a mounting plate 203. A regulating screw 204 is threadedly connected to the bottom of the mounting plate 203. One end of the regulating screw 204 is rotatably connected to the support column 102. The other end of the regulating screw 204 is fixedly provided with a turning handle. Rotating the turning handle can drive the regulating screw 204 to rotate, so that the sliding plate 201 can move along the direction of the slider 202, and further the distance between the sliding plate 201 and the tire embryo 104 can be adjusted, thereby ensuring a reasonable distance is maintained between the clamping plate 207 and the tire embryo 104. A telescopic cylinder 205 is hinged to the top of the mounting plate 203. The output end of the telescopic cylinder 205 is connected to the clamping component. When the telescopic cylinder 205 acts, it will provide a pulling force for the whole clamping plate 207 to move towards the side of the mounting plate 203, helping the component to separate from the tire embryo 104.

[0037] As shown in Figures 2-5 , the clamping component includes an L-shaped moving plate 206. The output end of the telescopic cylinder 205 is hinged to the L-shaped moving plate 206. A clamping plate 207 is rotatably arranged on the side of the L-shaped moving plate 206 away from the telescopic cylinder 205. The clamping plate 207 moves along the sliding plate 201. A clamping plate cylinder 208 is hinged to the top of the L-shaped moving 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. During use, a part of the head is placed between the clamping plate 207 and the L-shaped moving plate 206, and driving the clamping plate cylinder 208 can clamp the head.

[0038] As shown in Figures 2-5As shown in the figure, the limit mechanism 300 includes adjusting lead screws 301 symmetrically arranged. On each of the adjusting lead screws 301, a strut seat 302 is threadedly arranged. On one side of the strut seat 302, a crank 303 is fixedly arranged. A number of movable seats 304 are evenly distributed on the outer side of the strut seat 302. A strut 305 is rotatably arranged on the movable seat 304. At the end of the strut 305, there is a clip 306 for fixing the tire embryo 104. At the ends of the opposite sides of the two adjusting lead screws 301, slide rods 307 are fixedly arranged. On the side of the slide rod 307 close to the adjusting lead screw 301, a stop piece 308 is fixedly arranged. The stop piece 308 is in a stationary state. When the strut seat 302 is shaken by the crank 303, the strut 305 will open under the action of the stop piece 308. At the same time, the clip 306 will lift the bead part of the tire embryo 104. A sleeve 309 is arranged between the two slide rods 307. The sleeve 309 is sleeved on the outer side of the slide rod 307 through a number of bolts, which is convenient for adapting to the inner bead spacing of different embryos. The sleeve 309 is made of a hollow iron pipe, which is convenient for retaining the original shape of the embryo to the greatest extent. The slide rod 307 is slidably connected with the sleeve 309, so that the two adjusting lead screws 301 are in a coaxial state. A rotating ring 310 is rotatably arranged on the outer side of the slide rod 307. A tension spring 311 is fixedly arranged between the rotating ring 310 and the strut 305. Select a tension spring 311 with appropriate tension according to the actual environment. The tension spring 311 provides a force for the strut 305 to move towards the rotating ring 310 side, and then cooperates with the stop piece 308 to limit the opening angle of the strut 305. To increase the stability effect, a telescopic guide rod can be arranged between the rotating ring 310 and the strut 305. The tension spring 311 is sleeved on the outer side of the telescopic guide rod to limit its radial swing and ensure the stable opening of the strut 305, avoiding the situation of twisting or winding when the tension spring 311 rotates. On one side of one of the adjusting lead screws 301, there is a rotating assembly for rotating the tire embryo 104, which is used to assist the tire removing mechanism 200 to achieve the tire removing effect.

[0039] Among them, as Figure 4 shown, the clip 306 includes a clip mother part 3061 fixedly connected with the strut 305. On one side of the clip mother part 3061, there is a clip sub-part 3062. The clip mother part 3061 and the clip sub-part 3062 are connected by clip screws. After the strut 305 is adjusted to the appropriate position, the bead part of the tire embryo 104 is placed between the clip mother part 3061 and the clip sub-part 3062, and the clip screws are tightened to fix the position of the tire embryo 104.

[0040] Among them, as Figure 3As shown, the rotating assembly includes a motor reduction gearbox 312 and a driving motor 313. Inside the motor reduction gearbox 312, there are components such as belts and gears, which are prior art. The rotational speed and torque of the driving motor 313 can be adjusted to enable the device to operate in an optimal working state. The motor reduction gearbox 312 is fixedly installed on the fixed column 103. The output end of the driving 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 driving motor 313, such that when the driving motor 313 is powered on, the brake is automatically released, and when the driving motor 313 is powered off, the brake immediately brakes the output end to prevent accidental rotation of the device. The output end of the motor reduction gearbox 312 is coaxially connected to the corresponding adjusting lead screw 301 through a coupling for convenient power transmission. After the driving motor 313 is started, the motor reduction gearbox 312 adjusts the rotational speed and torque input by the driving motor 313 according to its own transmission ratio, and then outputs the adjusted power from the output end to drive the adjusting lead screw 301 to operate. A foot pedal can be provided on one side of the base 101, and the foot pedal is electrically connected to the driving motor 313 to facilitate the forward and reverse operation control of the limiting mechanism 300.

[0041] As shown in Figure 1 and Figure 2 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 to facilitate outputting instructions and ensuring process automation.

[0042] As shown in Figure 1 and Figure 2 shown, a plurality of clamping teeth are fixedly provided on the lower surface of the clamping plate 207, and a rubber or polyurethane protective layer is covered outside the clamping teeth to avoid damaging the tire embryo while increasing the friction force.

[0043] As shown in Figure 2 shown, the adjusting screw 204 is arranged parallel to the inclined surface of the sliding plate 201, and the sliding paths of the sliding plate 201 and the sliding block 202 are parallel to the adjusting screw 204, such that when the handle is rotated, the sliding plate 201 and the sliding block 202 can be smoothly driven to move along the surface of the support column 102 to ensure the normal operation of the device.

[0044] Embodiment 2

[0045] The difference from Embodiment 1 is that as shown in Figure 6 and Figure 7As shown, the limiting mechanism 300 further includes a limiting ring rotatably arranged outside the sliding rod 307. A number of connecting blocks 314 are evenly distributed on the outside of the limiting ring. A moving rod 315 is fixedly arranged at the top of the connecting block 314. The moving rod 315 can slide smoothly in the groove 316. The groove 316 is formed inside the support rod 305. The moving rod 315 is movably connected to the inner wall of the groove 316. Compared with the retaining piece 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.

[0046] During use, first place the tire embryo 104 between the clamping pieces 306 of the limiting mechanism 300, clamp the bead part of the tire embryo 104 through the clamping pieces 306, rotate the crank 303 to rotate and adjust the screw rod 301, so that the support rod seat 302 drives the support rod 305 to cooperate with the retaining piece 308 to expand outwards, and then tighten the bead of the embryo. Adjust the position of the sleeve 309 according to the shape and size of the tire embryo 104, and fix the sleeve 309 on the sliding rod 307 through bolts to realize the adjustment of the inner spacing of the bead of the embryo, and complete the adjustment operation of the limiting mechanism 300. Rotate the handle of the adjusting screw rod 204 to drive the sliding plate 201 to slide along the support column 102, so that the clamping plate 207 and the tire embryo 104 maintain a reasonable distance. At this time, the output end of the telescopic cylinder 205 is in the extended state, and the clamping plate cylinder 208 drives the clamping plate 207 to move downward, so that the part of the blank 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 contract, so that the clamping plate 207 moves away from the tire embryo 104. The driving motor 313 drives the screw rod 301 to rotate through the motor reduction box 312, so that the tire embryo 104 rotates slowly, and cooperates with the tire removing mechanism 200 to realize the continuous peeling of the blank of the embryo. During the tire removing process, a small amount of gasoline or glue slurry and other materials can be sprayed at the blank to improve the peeling effect.

[0047] The above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed in the present application, and all should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
