Description

Technical Field

[0001] This invention relates to the field of tire cutting technology, specifically an integrated device for automatic cutting and positioning of bicycle tire tread. Background Technology

[0002] Bicycle tires are a key component of bicycles, usually made of rubber and mounted on the outside of the rim. They generate friction with the ground to propel the vehicle forward, provide cushioning, and ensure riding stability. With the continuous growth of bicycle ownership and the increasing awareness of environmental protection, the recycling and reuse of waste tires has become an important part of resource recycling. In particular, the tire tread, due to its rapid wear and high material remodelability, is often cut into specific sizes for the manufacture of recycled rubber products, the laying of sports fields, or as industrial filler material, thereby realizing the resource utilization of waste.

[0003] When cutting waste bicycle tires, manual positioning and clamping of the tires is usually required, which is inefficient and poses certain safety hazards. The cutting device cannot control the cutting length according to the specifications of the recycled materials, resulting in low utilization of the cut materials, insufficient equipment flexibility, and difficulty in achieving fast and accurate tire cutting operations. Summary of the Invention

[0004] The purpose of this invention is to provide an integrated automatic tire tread cutting and positioning device for bicycles, so as to solve the problem of the inconvenience of existing tire cutting.

[0005] To achieve the above objectives, the present invention provides the following technical solution: An integrated automatic cutting and positioning device for bicycle tire treads includes a support column and further includes: The clamping assembly, which can compress and fix the inserted tire, includes a support frame set outside the support column, a rotating frame set on the support frame, and a pressure block set on the rotating frame and the support frame. The outer wall of the support column is provided with a sliding groove, and one end of the support frame is provided with an installation block. The installation block is slidably set inside the sliding groove. The support frame is provided with a guide rail, a slider is provided on the guide rail, and the rotating frame is provided on the slider. The cutting assembly includes a movable frame mounted on a support frame, a cutting blade mounted on the movable frame, and a connecting block mounted on a rotating frame. The support frame has a guide groove inside, the movable block is mounted inside the guide groove, the movable frame is mounted on the movable block, the movable frame has a slot, the rotating frame has an installation groove, the connecting block is slidably mounted inside the installation groove, and the connecting block has a locking block that cooperates with the slot. The transmission assembly includes a connecting rope disposed on the movable block and the connecting block, a guide cylinder disposed on the support frame, and a movable cylinder slidably disposed at the bottom of the guide cylinder. One end of the connecting rope passes through the guide cylinder and is connected to the movable cylinder. A lifting ring is slidably disposed on the outside of the support column. A sliding block is disposed on the lifting ring. A guide ring is disposed on the sliding block. A rotating wheel is disposed at the bottom of the movable cylinder. A traction rope is disposed between the rotating wheel and the guide ring. The drive mechanism is connected to the lifting ring and drives the lifting ring to descend. The lifting ring drives the cutting assembly to move through the cooperation of the traction rope, the movable cylinder and the connecting rope.

[0006] Based on the above technical solutions, the present invention also provides the following optional technical solutions: In one alternative embodiment: the driving mechanism includes a lifting cylinder, a rotating plate, and a turntable; a fixed plate is provided inside the support column; a turntable is provided on the fixed plate; a transmission column is provided on the turntable; the rotating plate is rotatably mounted on the fixed plate; a square groove is provided on the rotating plate to cooperate with the transmission column; a lifting cylinder is slidably arranged inside the support column; a groove is provided on the inner wall of the lifting cylinder; and a top plate is provided at one end of the rotating plate to cooperate with the groove.

[0007] In one alternative: a limiting rod is slidably provided at the top of the fixing plate, one end of the limiting rod is provided with a reset spring, and the other end of the limiting rod passes into the groove.

[0008] In one alternative embodiment: a drive rod is provided on the fixed plate, the turntable is mounted on the drive rod, and a power component for driving the drive rod to rotate is provided on the fixed plate.

[0012] In one alternative: a support box is provided at the bottom of the support column, and a storage cabinet is provided inside the support box.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: The integrated automatic cutting and positioning device for bicycle tire treads uses a support frame and a rotating frame to fix the tire in place with pressure blocks. The cutting blade then cuts the tire. The position adjustment of the clamping blocks and the cutting blade is convenient. The clamping assembly connects the clamping blocks and the clamping slots, automatically connecting and locking the cutting mechanism while clamping the tire. No additional operation steps are required, achieving quick tire fixation. This ensures that the cutting assembly can only be activated after the tire is fixed, enhancing the safety of the equipment.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0025] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0026] like Figure 1-9 As shown, an integrated automatic cutting and positioning device for bicycle tire treads, according to an embodiment of the present invention, includes a support column 1 and further includes: The clamping assembly, capable of compressing and fixing the inserted tire, includes a support frame 2 located outside the support column 1, a rotating frame 8 mounted on the support frame 2, and pressure blocks 3 mounted on the rotating frame 8 and the support frame 2. A mounting plate 12 is located at the bottom of the support column 1, and the mounting plate 12 is fixed to the top of the support box 10 by bolts 16, thereby stably and vertically mounting the support column 1 on the support box 10. Multiple buffer posts 13 are provided on the mounting plate 12. A sliding groove 101 is formed on the outer wall of the support column 1. A mounting block 202 is provided at one end of the support frame 2, and the mounting block 202 is slidably disposed inside the sliding groove 101. The support frame 2 can rotate around the outer wall of the support column 1, facilitating flexible adjustment of the cutting position of the tire body 4 according to cutting requirements. The support frame 2 is equipped with a guide rail 7, a slider 9 is mounted on the guide rail 7, and a rotating frame 8 is rotatably mounted on the slider 9. When no tire is placed, the pressure block 3 is in a free state and its position is adjustable to accommodate tires of different sizes. The inner wall of the pressure block 3 is fitted with a friction layer made of a high-friction coefficient material to enhance the anti-slip effect during clamping. When the tire is placed, the rotating frame 8 rotates downward around the pivot on the slider 9 to a horizontal position. At this time, the support frame 2 and the pressure block 3 on the rotating frame 8 approach each other and dock. As the clamping action is completed, the friction layer on the inner wall of the pressure block 3 comes into close contact with the tire surface and the support components (support frame 2 and rotating frame 8), ensuring that the pressure block 3 does not shift during the cutting process and achieving stable clamping of the tire. The cutting assembly includes a movable frame 5 mounted on a support frame 2, a cutting blade 6 mounted on the movable frame 5, and a connecting block 29 mounted on a rotating frame 8. The support frame 2 has a guide groove 201 inside, and a movable block 30 is slidably disposed within the guide groove 201. The rotating frame 8 has a mounting groove 801, and the connecting block 29 is slidably disposed within the mounting groove 801. Both the movable block 30 and the connecting block 29 are mounted using elastic elements (such as telescopic springs), and both are in a neutral position when not subjected to external force. Figure 1 In the initial position shown, the movable frame 5 is fixedly mounted on the movable block 30. The movable frame 5 is provided with a slot 501, and the connecting block 29 is provided with a locking block 17 that mates with the slot 501. The locking block 17 is an arc-shaped plate, and the slot 501 is a matching arc-shaped groove, allowing the locking block 17 to pass into the slot 501, thus achieving docking between the movable frame 5 and the connecting block 29. Before the cutting operation, the rotating frame 8 is in the position shown. Figure 1 As shown in the upward flip position, the tire to be cut is placed on the multiple pressure blocks 3 on the support frame 2, and the rotating frame 8 is flipped downward to a horizontal position (as shown). Figure 5As shown), the tire is pressed and fixed by the pressure blocks 3 on both sides. During this process, the connecting block 29 rotates with the rotating frame 8, and the locking block 17 on it is simultaneously inserted into the locking groove 501 of the movable frame 5. The movable frame 5 is provided with a spring piece 502, and the locking block 17 on the connecting block 29 is correspondingly provided with multiple sets of inclined grooves 171. When the locking block 17 is inserted into the locking groove 501, the spring piece 502 is locked into the inclined groove 171, forming a mechanical interlock, so that the locking block 17 cannot be reset upward, ensuring that the movable frame 5 and the connecting block 29 cannot be separated during the cutting process, thereby realizing the docking and fixing between the support frame 2 and the rotating frame 8. During the cutting, the drive mechanism drives the movable frame 5 to slide along the guide groove 201, and the cutting blade 6 on the movable frame 5 moves accordingly to complete the cutting of the tire. The transmission assembly includes a connecting rope 14 mounted on the movable block 30 and the connecting block 29, a guide cylinder 18 mounted on the support frame 2, and a movable cylinder 19 slidably mounted at the bottom of the guide cylinder 18. One end of the connecting rope 14 passes through the guide cylinder 18 and connects to the movable cylinder 19. A lifting ring 25 is slidably mounted on the outside of the support column 1. A sliding block 27 is mounted on the lifting ring 25, and a guide ring 26 is mounted on the sliding block 27. A rotating wheel 28 is mounted at the bottom of the movable cylinder 19. A traction rope 24 is mounted between the rotating wheel 28 and the guide ring 26. Both ends of the traction rope 24 are fixed to the lifting ring 25 and pass sequentially around the rotating wheel 28 and the guide ring 26 to form a closed-loop transmission (corresponding to...). Figure 3 (As shown in the position), when the lifting ring 25 is subjected to force and moves downward, the traction rope 24 pulls the rotating wheel 28 downward, thereby driving the movable cylinder 19 to move down along the guide cylinder 18. The movable cylinder 19 synchronously pulls the movable block 30 and the connecting block 29 through the connecting rope 14, overcoming the resistance of the elastic element and moving, and finally driving the movable frame 5 and the cutting blade 6 to feed towards the tire and perform the tire cutting operation. The traction rope 24 and the rotating wheel 28 have an adaptive adjustment function. When the tire tread has uneven local hardness or thickness, resulting in increased cutting resistance and delayed progress on one side, the movement of the corresponding movable block 30 or connecting block 29 will be obstructed. At this time, the tension on the connecting rope 14 changes, forcing the movable cylinder 19 and the rotating wheel 28 to move. Then, the guide ring 26 on the sliding block 27 is driven to slide adaptively through the traction rope 24, adjusting the transmission path and tension distribution of the traction rope 24 in real time to ensure that the force on multiple sets of connecting ropes 14 is the same, ensuring balanced cutting force and preventing the tire from deflecting or being damaged due to uneven force. The drive mechanism is connected to the lifting ring 25 and drives the lifting ring 25 to descend. The lifting ring 25 drives the cutting component to move through the cooperation of the traction rope 24, the movable cylinder 19 and the connecting rope 14.

[0027] like Figure 1-9As shown, in a preferred embodiment of the present invention, the driving mechanism includes a lifting cylinder 35, a rotating plate 37, and a turntable 39. A fixed plate 34 is vertically arranged inside the support column 1, and a turntable 39 is arranged on the fixed plate 34. A transmission column 391 is arranged on the turntable 39. The rotating plate 37 is rotatably mounted on the fixed plate 34. The rotating plate 37 is rotatably mounted on the fixed plate 34 via a rotating shaft at one end, and can swing up and down within a certain angle range around the rotating shaft. A top plate 38 is rotatably arranged at the other end of the rotating plate 37. A square groove 371 is opened on the rotating plate 37, and one end of the transmission column 391 passes through the square groove 371. The lifting cylinder 35 is slidably arranged inside the support column 1. A horizontal plate 251 is arranged between the lifting cylinder 35 and the lifting ring 25. A limit groove 103 is opened on the support column 1, and the horizontal plate 251 slides along the limit groove 103. The inner wall of the lifting cylinder 35 is provided with... A groove 351 is provided, and the turntable 39 rotates under the drive of the power component. The transmission column 391 drives the rotating plate 37 to swing up and down around its axis through the square groove 371. During the downward swing of the rotating plate 37, the top plate 38 moves down with the rotating plate 37 and enters the groove 351, pushing the lifting cylinder 35 and the lifting ring 25 connected to it to descend as a whole. Then, through the transmission component, the cutting blade 6 is driven to feed towards the tire to perform the cutting operation. During the upward swing of the rotating plate 37, the top plate 38 is overturned by the force during the upward movement, which prevents it from pushing the lifting cylinder 35 to rise. The lifting cylinder 35 and the lifting ring 25 remain stationary, and the cutting blade 6 stops feeding. The intermittent descent ensures that the cutting blade 6 has sufficient dwell time during the cutting process, which can completely cut the tire tread material. This effectively avoids problems such as incomplete cutting and material tearing that may be caused by continuous feeding, thereby ensuring the flatness of the cut surface.

[0028] like Figure 8-9 As shown, in a preferred embodiment of the present invention, a limiting rod 36 is horizontally slidably provided at the top of the fixing plate 34. One end of the limiting rod 36 is provided with a return spring 40, and the other end of the limiting rod 36 is provided with an inclined guide surface that extends into the groove 351 of the inner wall of the lifting cylinder 35. When the lifting cylinder 35 is driven to descend by the top plate 38, the inclined guide surface of the limiting rod 36 is squeezed by the side wall of the groove 351, which can overcome the elastic force of the return spring 40 and slide outward, allowing the lifting cylinder 35 to descend. When the lifting cylinder 35 has an upward trend, the vertical bottom surface of the limiting rod 36 will interfere with the groove 351, jamming the groove 351 and preventing the lifting cylinder 35 from rebounding upward, thus ensuring the unidirectional movement of the lifting cylinder 35 during the cutting process.

[0029] like Figure 8-9 As shown, in a preferred embodiment of the present invention, a drive rod 41 is provided on the fixed plate 34, the turntable 39 is provided on the drive rod 41, and a power component for driving the drive rod 41 to rotate is provided on the fixed plate 34.

[0030] like Figure 1-3 As shown in the preferred embodiment of the present invention, the support column 1 is provided with a dial 15 at its top, and the guide cylinder 18 is provided with a pointer 22 at its top. The two work together to display the rotation angle of the support frame 2. The outer wall of the support column 1 is provided with a plurality of positioning holes 102. The guide cylinder 18 is provided with a positioning rod 21 that cooperates with the positioning holes 102. A spring 23 for resetting is provided outside the positioning rod 21. When it is necessary to adjust the cutting position, the user pulls the positioning rod 21 outward to disengage it from the current positioning hole 102, and the support frame 2 can be rotated to the target angle. At this time, the pointer 22 indicates the corresponding position on the dial 15. After alignment, the positioning rod 21 is released, and under the action of the spring 23, it automatically passes into the corresponding positioning hole 102, thereby realizing the positioning and locking of the support frame 2.

[0031] like Figure 1-8 As shown, in a preferred embodiment of the present invention, the movable frame 5 is provided with a rotating rod 503, the cutting blade 6 is provided on the rotating rod 503, the movable block 30 is provided with a drive motor 31, and both the drive motor 31 and the rotating rod 503 are provided with pulleys 32. A transmission belt 33 is provided between the two pulleys 32. The drive motor 31 drives the cutting blade 6 to rotate through the pulleys 32 and the transmission belt 33, providing power for cutting the tire.

[0032] like Figure 1-7 As shown, in a preferred embodiment of the present invention, the card block 17 is provided with a slanted groove 171, and the movable frame 5 is provided with a spring piece 502 that cooperates with the slanted groove 171, and the spring piece 502 can be pulled outward.

[0033] like Figure 1-3 As shown, in a preferred embodiment of the present invention, a support box 10 is provided at the bottom of the support column 1, and a storage cabinet 11 is provided inside the support box 10.

[0034] The above embodiments of the present invention provide an integrated device for automatic cutting and positioning of bicycle tire tread. The steps include adjusting the initial positions of the support frame 2 and the pressure blocks 3, placing the bicycle tire to be cut horizontally on the multiple pressure blocks 3 of the support frame 2, and flipping the rotating frame 8 downwards to a horizontal position, so that the pressure blocks 3 on the support frame 2 and the rotating frame 8 approach and align with each other, pressing the tire together through a friction layer. During this process, the connecting block 29 moves with the rotating frame 8, and its locking block 17 synchronously inserts into the locking groove 501 of the movable frame 5. The spring piece 502 engages in the inclined groove 171 of the locking block 17, forming a mechanical interlock. The support frame 2 and the rotating frame 8 are docked and fixed; the drive motor 31 pulley 32 and the transmission belt 33 drive the cutting blade 6 to rotate, start the power component of the drive mechanism (such as the motor), the turntable 39 drives the rotating plate 37 to swing up and down through the cooperation of the transmission column 391 and the square groove 371, the lifting cylinder 35 drives the lifting ring 25 to descend through the horizontal plate 251, the lifting ring 25 pulls the movable cylinder 19 down through the traction rope 24, the movable cylinder 19 synchronously pulls the movable block 30 and the connecting block 29 through the connecting rope 14, and drives the movable frame 5 and the cutting blade 6 to be steadily fed in the direction of the tire to perform the cutting operation.
