This patent achieves automatic double-sided trimming by automatically trimming and polishing both sides of the tire by activating a bidirectional shaft motor clamped in the rear housing on the left outer wall of the positioning bracket, thus improving trimming efficiency while saving manpower.

[0004] The aforementioned patent achieves automatic double-sided trimming and polishing, improving trimming efficiency while saving manpower. However, the current measuring equipment has the following problems: if the equipment is started before it is ready after the tire is clamped, the tire may become loose, resulting in uneven or inaccurate trimming, which affects the quality of the final product. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a tire manufacturing trimming device that solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a tire manufacturing trimming device, comprising a base and a tire, the tire being disposed on top of the base, and a clamping device, a trimming device, and an auxiliary device disposed above the base; wherein, the clamping device comprises a rotary motor, a drive shaft, a tripod, a clamping plate, a first spring, a lead screw, a sliding sleeve, an L-shaped rod, a connecting button, a protrusion, a center plate, a limit button, a second spring, a rack and pinion, a rotating rod, a gear, a fixed plate, a moving plate, and a third spring; the fixed end of the rotary motor is fixedly installed on the bottom of the base. The drive shaft is connected to the output end of the rotary motor via a first belt. The tripod is fixedly mounted on the top of the drive shaft, and the clamping plate is slidably mounted on the inner wall of the tripod. The first spring is positioned between the clamping plate and the tripod. By placing the tire on top of the tripod and the fixed plate, the outer wall of the tire contacts the clamping plate, causing the clamping plate to move and simultaneously stretching the compressed first spring. After placement, the first spring resets, clamping the outer wall of the tire. Rotating the lead screw drives the spiral groove to rotate, causing the sliding sleeve to move downwards. The movement of the sliding sleeve moves the connecting button. The movement of the connecting button causes the L-shaped rod to slide, eventually contacting and clamping the tire's inner wall. A first spring then resets the clamping plate. The lead screw is rotatably mounted on the top of the tripod. The sliding sleeve is slidably mounted on the circumferential surface of the lead screw. The L-shaped rod is slidably mounted on the inner wall of the tripod. One side of the connecting button is rotatably mounted on the surface of the sliding sleeve, and the other side is rotatably mounted on the surface of the L-shaped rod. The protrusion is fixedly mounted on the top inner wall of the lead screw. The central disc is rotatably mounted on the top inner wall of the lead screw. The limit button is rotatably mounted on the surface of the central disc. The second spring... A device is positioned between the central disc and the limit button. A second spring is used to reset the limit button. The rack is fixedly mounted on the surface of the limit button. The rotating rod is rotatably mounted on the top inner wall of the central disc. The gear is fixedly mounted on the circumferential surface of the rotating rod. The fixed plate is fixedly mounted on the top of the base. The movable plate is slidably mounted on the inner wall of the fixed plate. A third spring is positioned between the movable plate and the fixed plate. When the outer wall of the tire contacts the movable plate, the movable plate moves. As the movable plate moves, it stretches and compresses the third spring, which then resets the device. The third spring then drives the movable plate to reset.

[0007] According to the above technical solution, the circumferential surface of the lead screw is provided with a spiral groove, which is threadedly connected to the sliding sleeve. By rotating the lead screw, the spiral groove is driven to rotate, and the rotation of the spiral groove causes the sliding sleeve to move downward. The protrusion contacts the limit button, and the rack meshes with the gear.

[0008] According to the above technical solution, the trimming device includes an electric push rod, a fixed block, a sliding rod, a collection groove, and a No. 4 spring. The fixed end of the electric push rod is fixedly installed on the top of the moving plate, and the fixed block is fixedly installed on the output end of the electric push rod. The movement of the moving plate drives the fixed end of the electric push rod to move, which in turn moves the fixed block, allowing the trimming device to adaptively adjust to different tire sizes. The sliding rod slides through the inner and outer walls of the fixed block, and the collection groove is fixedly installed on the surface of the sliding rod. The No. 4 spring is disposed between the collection groove and the fixed block, and the No. 4 spring drives the collection groove to reset.

[0009] According to the above technical solution, the trimming device further includes an auxiliary wheel, a trimming knife, and a guide plate. The auxiliary wheel is disposed on the outer wall of the collection tank and contacts the outer wall of the tire. It will not be disturbed when contacting the rotating tire during trimming. The trimming knife is disposed on the inner wall of the collection tank, and the guide plate is fixedly installed on the inner wall of the collection tank.

[0010] According to the above technical solution, the trimming device further includes a fixing frame, a compaction sleeve, a storage box, and an air pump. The fixing frame is fixedly installed on the top of the base, the compaction sleeve is rotatably installed on the inner wall of the fixing frame, the storage box is located on the top of the compaction sleeve, the air pump is located on the top of the storage box, the circumferential surface of the compaction sleeve is provided with an air intake, the compaction sleeve and the storage box are connected by a pipe, the surface of the compaction sleeve is provided with a circular groove, the left side of the compaction sleeve is provided with a docking groove, and the bottom of the compaction sleeve is provided with a roller. After clamping the tire, the compaction sleeve is rotated 90° to contact the top of the tire, and the roller prevents collision with the rotating tire.

[0011] According to the above technical solution, the auxiliary device includes an electric push rod II and a grinding rod. The fixed end of the electric push rod II is fixedly installed on the surface of the base, and the grinding rod is set at the output end of the electric push rod II. The grinding rod descends by lowering the output end of the electric push rod II, and the outer wall of the trimmed tire is ground by the grinding rod.

[0012] According to the above technical solution, the auxiliary device further includes a hollow block and a pressure rod. The hollow block is fixedly installed on the surface of the fixed frame. One side of the pressure rod slides through the inner and outer walls of the fixed frame, and the other side of the pressure rod slides through the compaction sleeve. Before rotating the compaction sleeve, the pressure rod is moved downward to release it from the restriction of the compaction sleeve.

[0013] According to the above technical solution, the auxiliary device further includes an insert rod, a brake block, a hollow cylinder, a round button, and a No. 6 spring. The insert rod is slidably installed on the inner wall of the hollow block. The brake block is fixedly installed on the left side of the insert rod. The hollow cylinder is fixedly installed on the left side of the hollow block. The round button is rotatably installed on the circumferential surface of the hollow cylinder. The No. 6 spring is disposed between the insert rod and the hollow block. The No. 6 spring drives the insert rod to reset. The circumferential surface of the hollow cylinder is provided with a second spiral groove. The second spiral groove is threadedly connected to the round button. Rotating the compaction sleeve causes it to contact the inclined surface of the insert rod, causing the insert rod to move to the right. As the insert rod moves, it compresses the No. 6 spring. When the insert rod and the docking groove are on the same horizontal plane, the No. 6 spring is released and drives the insert rod to insert into the docking groove, thus completing the fixation of the compaction sleeve.

[0014] This invention provides a tire manufacturing trimming device. It has the following beneficial effects:

[0015] This invention, through the design of a clamping device, places the tire on top of a triangular frame and a fixed plate, and clamps it by contacting the inner wall of the tire with an L-shaped rod. The adaptive clamping mechanism can handle tires of various sizes without requiring the replacement of specialized clamps, thereby improving the flexibility of the production line and the versatility of the equipment. It reduces downtime required for clamp changes, accelerates the production pace, and improves overall production efficiency. After the tire is clamped, a rotary motor, in conjunction with a drive shaft and a triangular frame, prepares the tire for rotational trimming. Limit buttons and protrusions restrict the rotation of the lead screw, preventing accidental reversal that could cause the clamping to lose its effectiveness, leading to tire instability and movement, and affecting the efficiency of subsequent trimming operations. By preventing reversal, continuous production and operation can be maintained, improving work efficiency. This invention, through the setting of the trimming device, uses the movement of the moving plate in conjunction with the electric push rod and the fixed block to allow the trimming device to adaptively adjust to different tire sizes, ensuring contact with the trimmed area. A collection trough collects the rubber cut by the trimming blade and discharges it through a guide plate. When encountering a thicker trimmed area, the sliding rod and spring No. 4 cushion the movement of the collection trough, preventing contact with the rotating tire and thus avoiding damage to the trimming blade from the force generated by rotation. After clamping the tire, a 90° rotation of the compaction sleeve contacts the top of the tire, preventing the tire from moving or rotating during the trimming process. This ensures that the trimming blade can accurately and evenly remove excess rubber. Clamping also ensures the repeatability and consistency of the trimming operation, improving the trimming quality. By releasing the clamping sleeve from its restraints with the pressure rod, it contacts the inclined surface of the insert rod and, in conjunction with the No. 6 spring and the mating groove, secures the clamping sleeve, preventing it from wobbling and causing tire instability and operational errors. The electric push rod, in conjunction with the edge-grinding rod, removes unevenness and burrs generated during the trimming process, resulting in smoother and neater tire edges. This not only improves the tire's appearance but also helps reduce rolling resistance. An air pump draws in the debris generated during grinding through the suction port and collects it in a storage tank via a pipe. Rubber debris scattered in the work area during grinding can affect the cleanliness of the work environment, increase cleaning difficulty, and potentially adversely affect the health of workers.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figures 1-7One embodiment of the present invention is: a tire production trimming device, including a base 1 and a tire 2, the tire 2 being disposed on the top of the base 1, and a clamping device disposed above the base 1, the clamping device including a rotary motor 10, a drive shaft 11, a tripod 12, a clamping plate 121, a first spring 122, a lead screw 13, a sliding sleeve 14, an L-shaped rod 15, a connecting button 16, a protrusion 17, a center plate 18, a limit button 19, a second spring 110, a rack 111, a rotating rod 112, a gear 113, a fixed plate 114, a moving plate 115, and a third spring 116, the fixed end of the rotary motor 10 being fixedly mounted on the base 1. At the bottom, the drive shaft 11 is connected to the output end of the rotary motor 10 via a first belt. A tripod 12 is fixedly mounted on the top of the drive shaft 11. A clamping plate 121 is slidably mounted on the inner wall of the tripod 12. A first spring 122 is positioned between the clamping plate 121 and the tripod 12, causing the clamping plate 121 to return to its original position. A lead screw 13 is rotatably mounted on the top of the tripod 12. A sliding sleeve 14 is slidably mounted on the circumferential surface of the lead screw 13. An L-shaped rod 15 is slidably mounted on the inner wall of the tripod 12. One side of the connecting button 16 is rotatably mounted on the surface of the sliding sleeve 14. This configuration allows for the handling of various tire sizes without the need for specialized tire replacement. The fixture improves the flexibility of the production line and the versatility of the equipment, reduces downtime required for fixture changes, speeds up the production pace, and improves overall production efficiency. The other side of the connecting button 16 is rotatably mounted on the surface of the L-shaped rod 15. The protrusion 17 is fixedly mounted on the top inner wall of the lead screw 13. The center plate 18 is rotatably mounted on the top inner wall of the lead screw 13. The limit button 19 is rotatably mounted on the surface of the center plate 18. A second spring 110 is positioned between the center plate 18 and the limit button 19. The second spring 110 drives the limit button 19 to reset. The rack rod 111 is fixedly mounted on the surface of the limit button 19. The rotating rod 112 rotates... The rotating rod 112 is fixedly mounted on the circumferential surface of the rotating rod 112. After the tire 2 is fixed, the lead screw 13 is accidentally reversed, causing the clamping effect to be lost. This makes the tire 2 unstable and causes it to move, affecting the efficiency of subsequent trimming operations. By preventing reverse rotation, continuous production and operation can be maintained, improving work efficiency. The fixed plate 114 is fixedly mounted on the top of the base 1. The moving plate 115 is slidably mounted on the inner wall of the fixed plate 114. The third spring 116 is set between the moving plate 115 and the fixed plate 114. The third spring 116 drives the moving plate 115 to reset.

[0029] The lead screw 13 has a spiral groove on its circumferential surface. The spiral groove is threadedly connected to the sliding sleeve 14. When the spiral groove rotates, the sliding sleeve 14 moves downward. The protrusion 17 contacts the limit button 19, and the rack rod 111 meshes with the gear 113.

[0030] In this embodiment, the tire 2 is placed on top of the tripod 12 and the fixed plate 114. The outer wall of the tire 2 contacts the clamping plate 121, causing the clamping plate 121 to move and simultaneously stretching the compressed spring 122. After placement, the tire 2 is reset by the spring 122. Simultaneously, the outer wall of the tire 2 contacts the moving plate 115, causing the moving plate 115 to move. The moving plate 115 stretches the compressed spring 116, which is then reset. This method clamps the outer wall of the tire 2. Rotating the lead screw 13 causes the spiral groove to rotate, which in turn moves the sliding sleeve 14 downwards. The movement of the sliding sleeve 14 moves the connecting button 16, causing the L-shaped rod 15 to slide and finally contact the inner wall of the tire 2 for clamping. This method can handle tires of various sizes without requiring the replacement of special clamps, thus improving the flexibility of the production line and the versatility of the equipment. It reduces downtime required for clamp replacement, speeds up production, and improves overall production efficiency. After clamping, the rotary motor 10 rotates, driving the drive shaft 11 to rotate via the first belt. The rotation of the drive shaft 11 drives the tripod 12 to rotate, preparing for the rotational trimming of the tire 2. Simultaneously, the lead screw 13 rotates, causing the protrusion 17 to rotate. The rotation of the protrusion 17 contacts the inclined surface of the limit button 19, causing the limit button 19 to rotate and compress the second spring 110. When the lead screw 13 reverses direction, the non-inclined surface of the protrusion 17 contacts the limit button 19, thus restricting the rotation of the lead screw 13. If the lead screw 13 is accidentally reversed after the tire 2 is fixed, the clamping effect will be lost, causing the tire 2 to become unstable and move, affecting the efficiency of subsequent trimming operations. By preventing the reverse rotation, continuous production and operation can be maintained, improving work efficiency. By rotating the rotating rod 112, the gear 113 is driven to rotate. The rotation of the gear 113 causes the rack rod 111 to move. The movement of the rack rod 111 causes the limit button 19 to rotate, so that the limit button 19 is released from the restriction of the protrusion 17. At this time, the lead screw 13 can be rotated normally.

[0031] Please see Figures 1-10Based on the above embodiments, in another embodiment of the present invention, a trimming device and an auxiliary device are provided above the base 1. The trimming device includes an electric push rod 20, a fixed block 21, a sliding rod 22, a collection groove 23, and a No. 4 spring 24. The fixed end of the electric push rod 20 is fixedly installed on the top of the moving plate 115, the fixed block 21 is fixedly installed on the output end of the electric push rod 20, the sliding rod 22 slides through the inner and outer walls of the fixed block 21, and the collection groove 23 is fixedly installed on the surface of the sliding rod 22, so that the trimming device can adaptively adjust to different tire sizes 2 to ensure that it can contact the trimmed area. The No. 4 spring 24 is set between the collection groove 23 and the fixed block 21. The No. 4 spring 24 drives the collection groove 23 to reset. The movement of the collection groove 23 drives the sliding rod 22 to move while compressing the No. 4 spring 24, so that the movement of the collection groove 23 is buffered.

[0032] The trimming device also includes an auxiliary wheel 25, a trimming blade 26, and a guide plate 27. The auxiliary wheel 25 is set on the outer wall of the collection tank 23, the trimming blade 26 is set on the inner wall of the collection tank 23, and the guide plate 27 is fixedly installed on the inner wall of the collection tank 23. The cut rubber skin will enter the collection tank 23 and be discharged through the guide plate 27. When encountering a thicker trimmed area, the collection tank 23 will move by contacting the outer wall of the tire 2 to prevent the trimming blade 26 from being damaged by the force generated by the rotation of the tire 2.

[0033] The trimming device also includes a fixed frame 28, a compaction sleeve 29, a storage box 210, and an air pump 211. The fixed frame 28 is fixedly installed on the top of the base 1. The compaction sleeve 29 is rotatably installed on the inner wall of the fixed frame 28. The storage box 210 is located on the top of the compaction sleeve 29. The air pump 211 is located on the top of the storage box 210. An air intake is provided on the circumferential surface of the compaction sleeve 29. The compaction sleeve 29 and the storage box 210 are connected by a pipe. A circular groove is provided on the surface of the compaction sleeve 29. A docking groove is provided on the left side of the compaction sleeve 29. A roller is provided at the bottom of the compaction sleeve 29. After clamping the tire 2, the compaction sleeve 29 is rotated 90° to contact the top of the tire 2. The roller prevents collision with the rotating tire 2, which can prevent the tire 2 from moving or rotating during the trimming action. This ensures that the trimming knife 26 can accurately and evenly remove excess rubber. The clamping also ensures the repeatability and consistency of the trimming operation and improves the trimming quality.

[0034] The auxiliary device includes an electric push rod 30 and a grinding rod 31. The fixed end of the electric push rod 30 is fixedly installed on the surface of the base 1, and the grinding rod 31 is set at the output end of the electric push rod 30. Through grinding, the unevenness and burrs generated during the trimming process can be removed, making the edge of the tire 2 smoother and neater. This not only improves the appearance of the tire 2, but also helps to reduce rolling resistance.

[0035] The auxiliary device also includes a hollow block 32 and a pressure rod 33. The hollow block 32 is fixedly installed on the surface of the fixed frame 28. One side of the pressure rod 33 slides through the inner and outer walls of the fixed frame 28, and the other side of the pressure rod 33 slides through the compaction sleeve 29. Before rotating the compaction sleeve 29, the pressure rod 33 is moved downward to release the pressure rod 33 from the restriction of the compaction sleeve 29.

[0036] The auxiliary device also includes an insert rod 35, a brake block 36, a hollow cylinder 37, a round button 38, and a No. 6 spring 39. The insert rod 35 is slidably mounted on the inner wall of the hollow block 32. The brake block 36 is fixedly mounted on the left side of the insert rod 35. The hollow cylinder 37 is fixedly mounted on the left side of the hollow block 32. The round button 38 is rotatably mounted on the circumferential surface of the hollow cylinder 37. The No. 6 spring 39 is located between the insert rod 35 and the hollow block 32. The No. 6 spring 39 drives the insert rod 35 to reset, thus fixing the compaction sleeve 29 and preventing the compaction sleeve 29 from shaking and causing the tire 2 to lose stability and cause operational errors. The circumferential surface of the hollow cylinder 37 is provided with a spiral groove II, which is threadedly connected to the round button 38. The spiral groove II allows the round button 38 to move along the hollow cylinder 37.

[0037] In this embodiment, the movement of the moving plate 115 drives the fixed end of the electric push rod 20 to move. The movement of the fixed end of the electric push rod 20 causes the fixed block 21 to move, allowing the trimming device to adaptively adjust to different tire sizes 2 to ensure contact with the trimmed area. The auxiliary wheel 25 contacts the outer wall of the tire 2, ensuring no interference when contacting the rotating tire 2 during trimming. The continuous descent of the output end of the electric push rod 20 causes the trimming blade 26 to contact the trimmed area and cut it. The cut rubber skin enters the collection trough 23 and is discharged through the guide plate 27. When encountering a thicker trimmed area... When the tire 2 is in contact with the outer wall of the tire 2, the collection groove 23 moves. The movement of the collection groove 23 drives the sliding rod 22 to move and compresses the No. 4 spring 24, so that the movement of the collection groove 23 is buffered, preventing the trimming knife 26 from being damaged by the force generated by the rotation when it comes into contact with the rotating tire 2. After the tire 2 is clamped, the compaction sleeve 29 is rotated 90° to contact the top of the tire 2, and the roller prevents it from colliding with the rotating tire 2. This can prevent the tire 2 from moving or rotating during the trimming action, thereby ensuring that the trimming knife 26 can accurately and evenly remove excess rubber. Clamping can also ensure the repeatability and consistency of the trimming operation and improve the trimming quality.

[0038] Before rotating the compaction sleeve 29, the pressure rod 33 is moved downwards to release it from its constraint on the compaction sleeve 29. Rotating the compaction sleeve 29 then brings it into contact with the inclined surface of the insertion rod 35, causing the insertion rod 35 to move to the right. As the insertion rod 35 moves, it compresses the No. 6 spring 39. When the insertion rod 35 is on the same horizontal plane as the mating groove, the No. 6 spring 39 is released, and the insertion rod 35 is inserted into the mating groove. This completes the fixation of the compaction sleeve 29, preventing it from shaking and causing the tire 2 to lose stability, thus avoiding operational errors. The output end of the electric push rod 30 descends, causing the grinding rod 31 to descend. The grinding rod 31 then grinds the outer wall of the trimmed tire 2, removing the trimmed edges. The unevenness and burrs generated during the edge-grinding process make the edge of the tire 2 smoother and neater, which not only improves the appearance of the tire 2, but also helps to reduce rolling resistance. The debris generated after grinding is sucked into the air intake by the air pump 211 and collected in the storage box 210 through the pipe. If the rubber debris generated during the grinding process is scattered in the work area, it will affect the cleanliness of the work environment, increase the difficulty of cleaning, and may have an adverse effect on the health of the workers. By rotating the round knob 38, the round knob 38 moves along the hollow cylinder 37 through the setting of the spiral groove 2. The movement of the round knob 38 will drive the insert rod 35 to move. At this time, the insert rod 35 is disengaged from the docking groove, and the compaction sleeve 29 can move freely.

[0039] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
