DETAILED DESCRIPTION

[0031] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with the embodiments and drawings, and the contents mentioned in the embodiments are not intended to limit the present invention. The present invention is described in detail below in conjunction with the drawings.

[0032] like Figure 1 and Figure 2 As shown, a tire grinding and glue spraying machine provided by the present invention includes a body 1, in which a moving mechanism 5, a clamping mechanism 2 for clamping the outer wall of the tire, a grinding mechanism 3 for grinding the inner wall of the tire, and a glue spraying mechanism 4 for spraying glue on the inner wall of the tire are arranged, and the moving mechanism 5 is used to drive the grinding mechanism 3 and the glue spraying mechanism 4 to move.

[0033] When the present invention is working, the existing staff puts the tire into the clamping mechanism 2, and the clamping mechanism 2 is operated to clamp the tire from the outside to the inside, that is, the clamping mechanism 2 clamps the outer wall of the tire, and then drives the grinding mechanism 3 to grind the inner wall of the tire and drives the glue spraying mechanism 4 to apply glue to the inner wall of the tire through the moving mechanism 5. The present invention clamps the tire from the outside to the inside, so that the inside of the tire is in an unobstructed state, which facilitates the grinding mechanism 3 and the glue spraying mechanism 4 to automatically grind and spray the inner wall of the tire respectively, thereby improving the fully automated processing of the tire and helping to improve the processing efficiency of the tire.

[0034] like Figure 3 and Figure 4 As shown, in this embodiment, the clamping mechanism 2 includes a turntable 21, a driving mechanism 23 and at least three clamping assemblies 22, the clamping assemblies 22 are distributed in a ring array on the end surface of the turntable 21, and the driving mechanism 23 is used to drive the clamping assemblies 22 to move toward or away from the center of the turntable 21; specifically, the number of the clamping assemblies 22 is preferably four, and the four clamping assemblies 22 are respectively slidably arranged on four bisectors of the end surface of the turntable 21. The clamping assemblies 22 are driven to move by one driving mechanism 23, which is conducive to ensuring the synchronization of the actions of the multiple clamping assemblies 22, and ensuring that the tire will not be clamped by the clamping assemblies 22 and deformed.

[0035] Specifically, the prior art clamps the tire from the inside out (clamps the inner sidewall of the tire) mainly based on the following considerations: clamping the tire from the outside in is unstable and can easily cause the tire to fall off. Figure 5As shown, in order to solve the above technical problems, the present embodiment adopts the following scheme: the clamping assembly 22 includes a clamping plate 24, a block 25 and two quick-release assemblies 26; a slide groove 241 and a plurality of pads 242 are provided on the side of the clamping plate 24 close to the center of the turntable 21; the plurality of pads 242 are arranged in parallel and located on the side wall of the slide groove 241; the pads 242 are used to be inserted into the pattern of the outer side wall of the tire; the outer surface of the pads 242 is inclined from the end away from the turntable 21 to the end close to the turntable 21; the block 25 is slidably arranged in the slide groove 241 and is used to prevent the tire from falling off; the quick-release assembly 26 is used to fix the block 25 in the slide groove 241; the two quick-release assemblies 26 are respectively arranged on both sides of the block 25; more specifically, the block 25 is used to contact with the end face of the tire away from the turntable 21 to achieve the effect of blocking the tire. That is, the present invention is provided with a pad 242, which is used to be stuck in the pattern of the tire, so as to clamp the tire while ensuring that the tire is not deformed as much as possible, which not only prevents the tire from escaping from the clamping assembly 22, but also avoids the deformation of the inner side of the tire that makes it difficult to install the metal rim; at the same time, the present invention is provided with a stopper 25 to prevent the tire from escaping from the present invention, and by setting the outer surface of the pad 242 to be inclined in the direction of the tire, it plays a role equivalent to a ratchet, so that the tire can only fall in the direction of the turntable 21 when it falls, and because the tire is close to the turntable 21 during operation, it is ensured that the tire will not shake back and forth due to uneven force.

[0036] Preferably, Figure 5As shown, the quick-release assembly 26 includes an anti-slip spring 261 and an anti-slip pin 262. The outer wall of the block 25 is provided with a receiving groove 251, and the anti-slip pin 262 is installed in the receiving groove 251. The anti-slip spring 261 is used to push the anti-slip pin 262 out of the receiving groove 251; the inner wall of the slide groove 241 is provided with a first tooth 2411, and the anti-slip pin 262 is provided with a second tooth 2621 for engaging with the first tooth 2411. Specifically, the anti-slip spring 261 is accommodated in the receiving groove 251, and one end of the anti-slip spring 261 abuts against the bottom wall of the receiving groove 251, and the other end of the anti-slip spring 261 abuts against one end of the anti-slip pin 262 away from the second tooth 2621. The quick-release assembly 26 facilitates the adjustment of the position of the stopper 25, that is, the present invention can stably clamp tires of various specifications for grinding and glue spraying, and its working principle is as follows: when the position of the stopper 25 needs to be adjusted, the anti-dropout pin 262 is pressed into the receiving groove 251, and the stopper 25 can slide in the slide groove 241; when the position of the stopper 25 is adjusted, the anti-dropout pin 262 is released, and the anti-dropout spring 261 will pop out the anti-dropout pin 262 until the first tooth 2411 is engaged with the second tooth 2621, thereby achieving the positioning of the stopper 25. In order to facilitate the pressing of the anti-dropout pin 262 into the receiving groove 251, a control screw 263 can be provided on the side wall of the anti-dropout pin 262, that is, the user can press the anti-dropout pin 262 into the receiving groove 251 by turning the control screw 263, which is convenient and quick to operate.

[0037] Specifically, Figure 3 and Figure 4 As shown, the driving mechanism 23 includes a driving component 231, a linkage seat 232, a transmission rod 233 and the same number of linkage rods 234 as the number of clamping components 22. The turntable 21 is provided with a clamping groove 211, and the clamping component 22 is slidably arranged in the clamping groove 211; the linkage seat 232 is concentrically arranged with the turntable 21, one end of the linkage rod 234 is rotatably arranged at a non-center position of the linkage seat 232, and the other end of the linkage rod 234 is rotatably connected to the clamping component 22; the driving component 231 is connected to the non-center position of the linkage seat 232 through the transmission rod 233, and preferably, one end of the transmission rod 233 is rotatably connected to one end of one of the linkage rods 234. When it is necessary to control the movement of the clamping assembly 22, the driving assembly 231 drives the linkage seat 232 to rotate through the transmission rod 233, thereby driving the linkage rod 234 to move: since the clamping assembly 22 slides in the clamping groove 211, and the linkage rod 234 is respectively rotatably connected to the linkage seat 232 and the clamping assembly 22, as the linkage seat 232 rotates, the linkage rod 234 will drive the clamping assembly 22 to move along the clamping groove 211 in the direction of approaching or moving away from each other, thereby achieving the effect of clamping or loosening the tire.

[0038] Preferably, Figure 6As shown, the driving assembly 231 includes a driving motor 2311, a driving reducer 2312, a universal joint 2313, a retaining spring 2314, a moving nut (not marked in the figure, a conventional component on the driving screw 2315) and a driving screw 2315. The driving motor 2311 is installed on the body 1, the universal joint 2313 is connected to the rotating shaft of the driving motor 2311 via the driving reducer 2312, the universal joint 2313 is installed in the retaining spring 2314, the driving screw 2315 is installed in the universal joint 2313, the moving nut is threadedly connected to the driving screw 2315, the other end of the transmission rod 233 is rotatably connected to the moving nut, and the driving screw 2315 drives the transmission rod 233 to move via the moving nut. That is, the present invention achieves the effect of slowly and accurately controlling the rotation of the driving screw 2315 by cooperating with the driving motor 2311 and the driving reducer 2312, thereby controlling the moving nut set on the driving screw 2315 to move back and forth, and the moving nut moving back and forth drives the transmission rod 233 to transfer, and then drives the linkage seat 232 to rotate back and forth; and the setting of the universal joint 2313 and the retaining spring 2314 increases the retaining force and supporting force of the present invention, so that the universal joint 2313 of the present invention will not deviate downward under the action of gravity after a long period of use, thereby ensuring the control accuracy.

[0039] Of course, if Figure 6 As shown, in order to improve the safety of the present invention, the driving assembly 231 also includes a fixed mounting plate 2316, a limiting plate 2317, a driving mounting plate 2318, a guide rod 2319, a lever 23110 and a detection switch, wherein the fixed mounting plate 2316 is fixed to the body 1, one end of the limiting plate 2317 is connected to the fixed mounting plate 2316, the limiting plate 2317 is provided with a limiting groove 23171, and the limiting groove 23171 is provided with two control positions 23172, the two control positions 23172 are respectively connected to the two ends of the limiting groove 23171, and the width of the control position 23172 is greater than the width of the limiting groove 23171; The rod 2319 is installed on the fixed mounting plate 2316, and the driving mounting plate 2318 is slidably set on the guide rod 2319. The lever 23110 includes a main body (not marked in the figure) and a control part (not marked in the figure). The width of the main body is adapted to the width of the control position 23172, and the width of the control part is adapted to the width of the limiting groove 23171. After passing through the limiting groove 23171, the control part is movably set in the driving mounting plate 2318; the detection switch is installed on the driving mounting plate 2318, and the detection switch is used to detect the position of the control part. The detection switch is electrically connected to the driving motor 2311.

[0040] The specific operation of the driving assembly 231 is controlled by the lever 23110 as follows: when the clamping assembly 22 needs to be moved, the lever 23110 is first pulled up so that the control unit is located in the control position 23172 away from the fixed mounting plate 2316, and then the lever 23110 is moved, and the driving mounting plate 2318 is driven to move by the lever 23110, that is, the driving motor 2311, the driving reducer 2312 and the universal joint 2313 are driven to move; when the lever 23110 moves to the control position 23172 close to the fixed mounting plate 2316, the lever 231 is pulled up. 10 is pressed down so that the body of the lever 23110 is installed in the control position 23172. At this time, the universal joint 2313 can just be sleeved on one end of the driving screw 2315, that is, the driving motor 2311 can drive the driving screw 2315 to rotate through the universal joint 2313 point when the driving motor 2311 is actuated, thereby achieving a control effect; and when there is no need to control the movement of the clamping assembly 22, it is only necessary to reset the lever 23110, so that the driving motor 2311 and the driving screw 2315 are separated when the present invention does not need to work to prevent the driving motor 2311 from malfunctioning and causing the tire to be clamped. At the same time, the detection switch is preferably a photoelectric switch, which is used to detect the position of the control unit to determine whether the driving mounting plate 2318 is in a moving state, thereby avoiding the safety accidents that may be caused by the malfunction of the driving motor 2311 when the driving mounting plate 2318 is in a moving state.

[0041] like Figure 7 As shown, in this embodiment, the grinding mechanism 3 includes a grinding motor 31, a grinding head 32, and a dust suction mechanism 33 for absorbing dust generated by the grinding head 32 when grinding the tire. The grinding head 32 is installed on the rotating shaft of the grinding motor 31. The grinding motor 31 and the dust suction mechanism 33 are both arranged on the moving mechanism 5. The dust suction mechanism 33 is located below the grinding head 32. The grinding head 32 is equipped with a monitoring switch for monitoring the grinding state. The grinding motor 31 drives the grinding head 32 to rotate to achieve the grinding of the inner wall of the tire, and then the dust suction mechanism 33 is used to absorb the powder produced by grinding to prevent the powder from adhering to the inner wall of the tire and affecting the gluing effect. The monitoring switch is set to ensure the grinding accuracy and prevent the grinding from being too deep and affecting the quality of the tire. The detection switch can be a high-precision shooting device such as an industrial camera.

[0042] Specific, combined Figure 7 and Figure 8As shown, the dust suction mechanism 33 includes a dust suction motor 331, a dust suction reducer 332, a pendulum 333, a connecting rod 334, a limiter 335 and a dust suction brush 336.

The other end of the pendulum 333 is rotatably connected to the connecting rod 334. The limiter 335 is rotatably connected to the moving mechanism 5. The connecting rod 334 is movably connected to the limiter 335. The dust suction brush 336 is installed on the limiter 335. The dust suction brush 336 is not only used for cleaning dust, but also for an external dust suction device. The pendulum 333 is preferably an eccentric piece. That is, the dust suction motor 331 and the dust suction reducer 332 cooperate to drive the pendulum 333 to rotate, thereby controlling the forward and backward movement of the connecting rod 334, thereby achieving the effect of controlling the swing of the limit member 335 and the dust suction brush 336 installed on the limit member 335, and allowing the dust suction brush 336 to sweep off and absorb the powder attached to the inner wall of the tire after grinding.

[0043] Combination Fig. 9 and Fig.10 As shown, in this embodiment, the glue spraying device includes a nozzle 41, a glue delivery pipe 42 and a suspension mechanism 43 for keeping the glue delivery pipe 42 in a suspended state, the nozzle 41 includes a main body 411, an air valve core 412 and a glue valve core 413, the main body 411 is provided with a sliding channel 4111, a connecting channel 4112, a main glue outlet channel 4113, a first air inlet hole 4114, a second air inlet hole 4115, a glue inlet port 4116 and two side glue outlet channels 4117, the first air inlet hole 4114 and the glue inlet port 4116 are both connected to one side of the sliding channel 4111, the second air inlet hole 4115 is connected to one end of the sliding channel 4111, and the other end of the sliding channel 4111 is connected to one end of the connecting channel 4112; the main glue outlet channel 4113 is connected to the connecting channel 411 2, and the other end of the two side glue channels 4117 are connected to the two sides of the connecting channel 4112 respectively; the air valve core 412 is slidably set in the sliding channel 4111, and the glue valve core 413 is installed on the air valve core 412, and the glue valve core 413 is located in the connecting channel 4112 and is used to control the connection between the connecting channel 4112 and the main glue channel 4113 or the side glue channel 4117, and the side wall of the air valve core 412 is provided with an isolating member 4118 for preventing the glue inlet 4116 from being connected to the first air inlet hole 4114 in the sliding channel 4111; the main glue channel 4113 and the two side glue channels 4117 are respectively provided with a spring 4119 and a glue blocking member 41110, and the spring 4119 is used to force the glue blocking member 41110 to block the connecting channel 4112.

[0044] That is, the present invention can choose to apply glue to the inner side wall or the inner end wall of the tire as needed, specifically as follows: when glue application is not required, no gas is passed into the first air inlet 4114 and the second air inlet 4115, and the main glue outlet channel 4113 and the side glue outlet channel 4117 are respectively equipped with a spring 4119 and a glue blocking member 41110. Therefore, the glue blocking member 41110 will, under the push of the spring 4119, block the connection between the main glue outlet channel 4113 and the connecting channel 4112, as well as the connection between the side glue outlet channel 4117 and the connecting channel 4112, so that the glue remaining in the nozzle 41 will not flow out of the glue outlet channel 4113 or the side glue outlet channel 4117 on its own; and when glue is required to be discharged from the main glue outlet channel 4113, the glue blocking member 4110 will block the connection between the main glue outlet channel 4113 and the connecting channel 4112, as well as the connection between the side glue outlet channel 4117 and the connecting channel 4112. Fig. 9 and Fig.10 For example, gas is introduced into the first air inlet 4114 to push the air valve core 412 and drive the glue valve core 413 to move to the right. The glue valve core 413 blocks the connection between the connecting channel 4112 and the side glue outlet channel 4117 and opens the connection between the connecting channel 4112 and the main glue outlet channel 4113, allowing the glue to flow into the main glue outlet channel 4113 through the glue inlet 4116 and the connecting channel 4112. Since the flow of glue is impactful, the impact force pushes open the glue blocking part 41110 and forces the spring 4119 to deform, allowing the main glue outlet channel 4113 to spray out the glue. The side glue outlet channel 4117 sprays glue by taking in air through the second air inlet 4115. The principle is the same as that of the main glue outlet channel 4113, which will not be repeated here. The present invention realizes the effect that a single nozzle 41 can control the main glue outlet 4113 or the side glue outlet 4117 to select one of the glue outlets, thereby simplifying the structure of the nozzle 41; at the same time, the nozzle 41 of the present invention is provided with a spring 4119 and a glue blocking member 41110, so that when no gas is introduced, the present invention can automatically block the outflow of the colloid inside the main body 411, thereby avoiding the waste of colloid and affecting the quality of glue coating.

[0045] In this embodiment, the suspension mechanism 43 is provided mainly because the glue spraying mechanism 4 in the present invention moves with the movement of the moving mechanism 5. If an ordinary glue delivery hose and an ordinary suspension mechanism are used, it is easy to cause glue leakage. Figure 2As shown, the suspension mechanism 43 in this embodiment specifically includes a basket screw 431, a wire rope 432, a pulley 433, an elastic rod 434 and a hanging piece 435. The rubber delivery tube 42 is made of Teflon material, and the rubber delivery tube 42 is wrapped with a heat insulation layer. One end of the wire rope 432 is connected to the body 1 through the basket screw 431, and the other end of the wire rope 432 is fixed to the body 1; the elastic rod 434 is bound to the rubber delivery tube 42 by a wire or a cable tie, and the elastic rod 434 is located at the bottom of the rubber delivery tube 42; the pulley 433 is slidably arranged on the wire rope 432, and the pulley 433 is connected to the rubber delivery tube 42 through the hanging piece 435; a glue tank 11 is arranged outside the body 1, and the rubber delivery tube 42 extends out of the body 1 and is connected to the glue tank 11. Since Teflon is resistant to high temperatures, it can be used for a long time without worrying about the deterioration of the rubber tube 42. In addition, a heat insulation layer is provided to prevent the high-temperature colloid from solidifying due to a drop in temperature. At the same time, since the present invention uses a pulley 433 and a steel wire rope 432 to slide to drive the rubber tube 42 to move, and an elastic rod 434 is tied to the bottom of the rubber tube 42, the elastic rod 434 is used to ensure that the rubber tube 42 will not break and facilitate the movement of the rubber tube 42, thereby preventing the rubber tube 42 from leaking. The turnbuckle 431 is used to adjust the tension of the steel wire rope 432 to ensure that the steel wire rope 432 will not loosen after a long period of use and affect the movement of the rubber tube 42.
