Description

Technical Field

[0001] This invention relates to the field of tire manufacturing, and in particular to a tread winding machine. Background Technology

[0002] With the continuous promotion of green production activities, how to achieve resource reuse and reduce dependence on new resources has become a key direction for current technological development. In the tire manufacturing industry, recycled waste rubber can be processed into reclaimed rubber powder, rubber, or carbon black through technologies such as physical crushing, desulfurization, or pyrolysis. These reclaimed materials can replace some raw materials in the production of tires or related materials. For example, the tread of a tire is mainly formed by repeatedly wound cords, which are mainly used to contact the ground and provide grip. Waste rubber can be used to manufacture the layer adhesive of the cords, which is used to bond the cords to the rubber layer of the tire.

[0003] When manufacturing tires, specialized winding equipment is required to evenly and tightly wind the ply fabric onto the tire's rubber skeleton. Related technology can be found in Chinese Patent No. CN221562335U, which discloses an aviation tire ply layer bonding mechanism. In use, two sets of hoops are fitted onto a rotating drum. The rubber component and ply fabric are then wound around the two sets of hoops. Adhesive is applied to the outside of the ply fabric, and the tire rubber layer is then wound around the outside of the ply fabric. The rotating drum then drives the ply fabric and tire rubber layer to rotate. A first bonding component is operated to press the ply fabric and tire rubber layer together, and a second bonding component is operated to press the edges of the ply fabric and tire rubber layer together, thus firmly bonding the tire rubber layer to the ply fabric. The mechanism includes a base plate, a vertical plate, a rotating shaft, and a rotating drum. The vertical plate is located at the top of the base plate, and a rotating shaft is rotatably mounted on the vertical plate. The rotating shaft is driven by a motor. The mechanism also includes a first bonding component and a second bonding component. The first bonding component is located on the vertical plate, and the second bonding component is located at the top of the base plate.

[0004] Regarding the aforementioned technologies, in order to ensure that the curtain fabric fits tightly against the rubber component, a rotating drum is needed to stretch the rubber component during the winding process, keeping it in a taut state to prevent deformation. Therefore, the rotating drum must have the function of radial expansion and contraction, similar to the structure of an umbrella frame, which has multiple radially movable support points. However, since the radial deformation structure is in an expanded state during operation, a gap needs to be left between adjacent support points. As a result, the stretched rubber component is more approximately polygonal than circular, leading to a tighter fit between the curtain fabric and the rubber component at the supported points during winding, affecting the uniformity of the curtain fabric winding. Summary of the Invention

[0005] To improve the uniformity of tire tread winding, this application provides a tire tread winding machine.

[0006] This application provides a tire tread winding machine, which adopts the following technical solution: A tire tread winding machine includes a frame with a rotating shaft that can rotate around its own axis. Several parallel arc-shaped plates are arranged circumferentially on the outer side of the rotating shaft. The rotating shaft is equipped with a pusher for driving all the arc-shaped plates to move radially. The side of each arc-shaped plate facing away from the rotating shaft is designated as an arc-shaped surface. When all the arc-shaped plates are in a state of moving away from each other, the arc-shaped surfaces of all the arc-shaped plates are coaxial. Several spacer plates are also arranged on the rotating shaft, staggered and parallel to the arc-shaped plates. The rotating shaft is equipped with a pusher for driving all the spacer plates to move synchronously closer to or away from the rotating shaft. The end face of each spacer facing away from the rotating shaft is designated as an arc-shaped surface. When the spacer is in a position away from the rotating shaft, the arc-shaped surface is coaxial with the arc-shaped surface, and at this time, all the arc-shaped plates and spacer plates cooperate to form a complete ring. A conveying mechanism is also provided on one side of the frame, and the conveying mechanism reciprocates along the axis of the rotating drum to uniformly convey the tire fabric to the rotating shaft.

[0007] By adopting the above technical solution, in the initial state, all the arc-shaped plates are close to each other. At this time, all the spacers are located inside the arc-shaped plates and avoid them. The rubber frame of the tire is placed on the outside of all the arc-shaped plates. The first pusher moves all the arc-shaped plates away from each other. At this time, all the arc-shaped plates cooperate to support the rubber part. When the arc-shaped plates reach the preset opening position, the second pusher moves all the spacers away from each other, so that the spacers fill the gap between two adjacent arc-shaped plates. At this time, all the first and second arc-shaped surfaces are coaxial and form a complete annular support surface to achieve uniform support for the rubber part, so that the rubber part is evenly supported. When winding the cord, the conveying mechanism is used to convey the cord to the rubber part so that the cord is evenly wound on the outside of the rubber part, which helps to improve the winding uniformity of the cord.

[0008] Optionally, the frame includes a vertical moving frame and a vertical moving platform. The vertical moving platform is vertically and liftably mounted on the vertical moving frame. The rotating shaft is horizontally mounted on one side of the vertical moving platform and is rotatably connected to the vertical moving platform around its own axis. The vertical moving platform is equipped with a rotating component for driving the rotating shaft to rotate.

[0009] By adopting the above technical solution, the vertical moving frame supports the vertical moving platform, so that the vertical moving platform moves synchronously with the rotating shaft. The vertical moving platform drives the rotating shaft to rotate through the rotating component, thereby rotating the rubber component. The vertical moving platform can be raised and lowered, which makes it easier to place the rubber component on the rotating shaft or remove the rubber component wrapped with the curtain from the rotating shaft, thus improving the convenience of work.

[0010] Optionally, the first pushing component includes two sets of opposing movable rings, each of which is slidably connected to the rotation axis along the axial direction. Several push rods are connected to the movable rings along the circumferential direction. When the movable rings move along the rotation axis, the push rods drive the arc-shaped plate closer to or away from the rotation axis. The second pushing component includes two movable rings, which are located between the two movable rings. The movable rings are also slidably connected to the rotation axis along the axial direction. Several push rods are arranged along the circumferential direction on the movable rings. When the movable rings move, the push rods drive the spacer plate closer to or away from the rotation axis. The rotation axis is equipped with a moving component, which is used to drive the movable rings one and two to move in stages.

[0011] By adopting the above technical solution, during operation, the moving part first drives the two moving rings to move closer to each other. When the moving rings move, they drive the arc plate away from the rotation axis through the push rod. When the moving rings move to the preset position, the moving part starts to drive the two moving rings to move closer to each other. Then, the push rod pushes the spacer into the gap between the two adjacent arc plates, thus completing the operation of opening the rubber part.

[0012] Optionally, the moving component includes a moving block, a power component, a rotating ring, and a rotating component. The moving block moves along the axis of rotation. The power component is mounted on the rotating shaft and provides power to the moving block. The rotating ring is located between moving ring one and moving ring two and is rotatably connected to the moving block around its own axis. An elastic component is provided between moving ring two and the rotating shaft. In its natural state, the elastic component pushes moving ring two closer to the rotating ring. A hook is provided on the side of the rotating ring closer to moving ring one. Moving ring one has a hooking part for connecting the hook. After the hook is connected to the hooking part, the rotating ring moves synchronously along the axial direction, causing moving ring one to move synchronously. The rotating component is mounted on the frame and is used to drive the rotating ring to rotate, so as to realize the connection and separation of the hook and the hooking part. Moving ring one also has a positioning component. When the arc plate is in the maximum open position, the hook and the hooking part are separated, and the positioning component positions moving ring one.

[0013] By adopting the above technical solution, under the support of the rotating shaft, the power component drives the moving block to move, causing the moving block to drive the rotating ring to move along the rotating shaft. Initially, the hook is connected to the hooking part. At this time, the rotating ring drives the first moving ring to move synchronously. When the arc-shaped plate opens to the preset position, the rotating component drives the rotating ring to rotate, causing the hook to separate from the hooking part. The positioning component then positions the first moving ring, completing the fixation of the arc-shaped plate. Under the action of the first elastic component, the two second moving rings move away from each other. The moving block continues to drive the rotating ring to move, causing the rotating ring to contact the second moving ring and drive the second moving ring to move.

[0014] Optionally, the rotating component includes a motor, a translation frame, and a transmission ring. A connecting ring is rotatably connected to the outer side of the rotating shaft around its own axis. An adjusting rod is fixedly connected to the connecting ring along the axial direction, and the adjusting rod passes through the rotating ring along the axial direction and is slidably connected to the rotating ring. Both the first and second moving rings have arc-shaped openings to avoid the adjusting rod. A support frame is fixedly provided at the upper end of the vertical moving frame, and the support frame extends to the side of the rotating shaft away from the vertical moving platform. The translation frame moves along the axis of the rotating shaft along the support frame, and the transmission ring is located on the side of the translation frame close to the rotating shaft and is coaxial with the rotating shaft in the working state. The motor is fixedly installed above the translation frame to drive the transmission ring to rotate. Multiple connecting blocks are fixedly provided on the side of the connecting ring close to the transmission ring, and the transmission ring has a slot adapted to the connecting blocks.

[0015] By adopting the above technical solution, after the vertical moving platform rises to the preset height, the transmission ring and the connecting ring are aligned and coaxial. When the translation frame moves closer to the rotating shaft, it drives the transmission ring to move closer to the connecting ring until the connecting block is inserted into the slot. At this time, the transmission ring is driven to rotate by motor one. Under the connection between the slot and the connecting block, the transmission ring drives the connecting ring to rotate synchronously, so that the connecting ring drives the rotating ring to rotate through the adjusting rod. During this process, the moving ring one and the moving ring two avoid the adjusting rod through the arc-shaped opening.

[0016] Optionally, the drive ring includes a positioning ring, a contact ring, and an elastic element two. The positioning ring is sleeved on the outside of the rotating shaft and rotatably connected to the rotating shaft. The contact ring is located on the side of the positioning ring away from the vertical moving stage and is slidably connected to the positioning ring along the axial direction. The connecting block is fixed to the side of the contact ring away from the positioning ring. When the contact ring rotates, it drives the positioning ring to rotate synchronously. The elastic element two is located between the positioning ring and the contact ring and is used to drive the contact ring away from the positioning ring. The positioning ring is fixedly connected to a limit block. Two limit grooves adapted to the limit blocks are opened on the outer surface of the rotating shaft along the circumferential direction. When the contact ring rotates, it drives the limit blocks to move between the two limit grooves. In its natural state, the limit block is inserted into any limit groove and restricts the rotation of the contact ring around its own axis.

[0017] By adopting the above technical solution, in the initial state, the contact ring moves away from the positioning ring under the action of the elastic element two, and the limiting block is located in any one of the limiting grooves. At this time, the hook is connected to the hooking part. When the transmission ring contacts the contact ring and drives the contact ring to approach the positioning ring, the elastic element two deforms, and the limiting block disengages from the limiting groove. When the transmission ring rotates, it drives the contact ring and the positioning ring to rotate synchronously. When the hook separates from the hooking part, the limiting block moves to another limiting groove. When the translation frame drives the transmission ring to reset, the contact ring resets under the action of the elastic element one and drives the limiting block to be inserted into the limiting groove, thereby restricting the rotation of the positioning ring and improving the working stability of the rotating ring.

[0018] Optionally, the positioning component includes a mounting ring and a positioning block. The mounting ring and the moving ring are rotatably connected coaxially, and the adjusting rod passes through the mounting ring and is slidably connected to the mounting ring along the axial direction. The positioning block is fixedly connected to the mounting ring and extends in a direction close to the axis of the rotating shaft. A straight groove is opened on the outer surface of the rotating shaft along the axial direction. When the positioning block is located in the straight groove, it moves along the straight groove. The rotating shaft also has an arc-shaped groove connected to the straight groove in the circumferential direction. When the rotating ring rotates, the positioning block moves between the straight groove and the arc-shaped groove. When the hook is disengaged from the hooking part, the positioning block is located in the arc-shaped groove and fits against the inner wall of the arc-shaped groove.

[0019] By adopting the above technical solution, when the moving ring moves along the axial direction, the mounting ring drives the positioning block to move along the straight groove. When the adjusting rod moves, it drives the mounting ring to rotate. At the same time as the hook disengages from the hook part, the mounting ring drives the positioning block into the arc groove. At this time, the rotating shaft restricts the movement of the moving ring along the axial direction through the positioning block, thereby achieving the positioning of the moving ring.

[0020] Optionally, the translation frame is also fixedly connected to a positioning shaft. The positioning shaft has a polygonal cross-section along the radial direction and is located inside the transmission ring and is rotatably connected to the transmission ring on the same axis. The end of the rotating shaft is provided with a polygonal hole that is adapted to the positioning shaft. When the connecting block is inserted into the slot, the positioning shaft is located inside the polygonal hole and fits against the inner wall of the polygonal hole.

[0021] By adopting the above technical solution, when the positioning shaft is inserted into the polygonal hole, the translation frame restricts the rotation of the rotating shaft through the positioning shaft, thereby facilitating the rotation of the connecting ring through the rotating component.

[0022] Optionally, the conveying mechanism includes a base, a movable frame, several conveying rollers, a heating roller, and a pressure roller. The movable frame is mounted on the base and reciprocates along the axis of rotation. The several conveying rollers are rotatably connected to the movable frame around their own axes to support and convey the curtain fabric. The heating roller is located on the side of the movable frame closer to the axis of rotation to heat the curtain fabric. A pressing frame is mounted on the movable frame and moves in a direction close to or away from the axis of rotation. The pressure roller is parallel to the axis of rotation and rotatably connected to the pressing frame to press the curtain fabric.

[0023] By adopting the above technical solution, the base supports the moving frame, which in turn is supported by the conveying rollers and drives the fabric to move. The fabric is wrapped around a heating roller, which heats the fabric, thereby increasing the adhesion of the fabric's adhesive layer. When the fabric is wrapped around the outside of the rubber component, the pressing frame drives the pressure rollers close to the rotating shaft, thus pressing the fabric firmly onto the rubber component. The width of the fabric is smaller than the width of the rubber component. When the moving frame moves, it causes the fabric to shift axially along the rubber component, thereby achieving uniform winding of the fabric.

[0024] In summary, this application includes at least one of the following beneficial technical effects: Initially, all the curved plates are close to each other, and all the spacers are located inside the curved plates, avoiding them. The tire's rubber frame is placed on the outside of all the curved plates. The first pusher moves all the curved plates away from each other, and all the curved plates cooperate to support the rubber component. When the curved plates reach the preset opening position, the second pusher moves all the spacers away from each other, filling the gap between two adjacent curved plates. At this time, all the first and second curved surfaces are coaxial and form a complete annular support surface to achieve uniform support for the rubber component, making the rubber component evenly supported. When the cord is wound, the conveying mechanism is used to transport the cord to the rubber component so that the cord is evenly wound on the outside of the rubber component, which helps to improve the winding uniformity of the cord. The base supports the moving frame, which in turn moves the fabric via conveyor rollers. Heating rollers wrap around the fabric, increasing its adhesive strength. When the fabric is wrapped around the outside of the rubber component, a pressing frame moves a pressure roller close to the rotating shaft, pressing the fabric firmly onto the rubber component. The width of the fabric is smaller than the width of the rubber component. As the moving frame moves, the fabric shifts axially along the rubber component, ensuring uniform winding.

[0033] The present application will be further described in detail below with reference to all the accompanying drawings.

[0034] This application discloses a tire tread winding machine. Example

[0035] Reference Figure 1 and Figure 2 A tire tread winding machine includes a frame 1 and a conveying mechanism disposed beside the frame 1. The conveying mechanism is used to convey the tire cord fabric and includes a base 31, a movable frame 32, a plurality of conveying rollers 33, a heating roller 34, and a pressure roller 35. The movable frame 32 is mounted on the base 31 and is slidably connected to the base 31 in the horizontal direction. The base 31 is equipped with a driving component for driving the movable frame 32 to move back and forth in a straight line. The driving component can be a commonly used mechanism in this technical field, such as a motor screw structure, which will not be described in detail.

[0036] Reference Figure 1 and Figure 2 Multiple conveyor rollers 33 are parallel to each other and rotatably connected to a movable frame 32 around their own axes. The movable frame 32 moves along the axis of the conveyor rollers 33. The fabric is sequentially wrapped around all the conveyor rollers 33 and moves along its length under the support of the conveyor rollers 33. A heating roller 34 is located on the side of the movable frame 32 closer to the frame 1. The fabric passes over the outside of the heating roller 34. When the heating roller 34 is working, it heats the fabric, thereby increasing the adhesion of the adhesive layer on the fabric. A pressing frame 36 is slidably connected to the movable frame 32 in the direction close to or away from the frame 1. The movable frame 32 is equipped with an electric actuator for moving the pressing frame 36. A pressure roller 35 is arranged parallel to the conveyor rollers 33 and rotatably connected to the pressing frame 36 around its own axis.

[0037] Reference Figure 1 and Figure 2 The frame 1 includes a vertically arranged vertical moving frame 11 and a vertical moving platform 12. The vertical moving platform 12 is mounted on the vertical moving frame 11 and moves vertically along the vertical moving frame 11. The vertical moving frame 11 is equipped with a lifting component for moving the vertical moving platform 12. The lifting component is a commonly used mechanism in this technical field, such as a cylinder, a hydraulic cylinder, a motor and gear rack combination structure, etc. In this embodiment, a motor screw structure is preferred, wherein the screw is arranged vertically and rotatably connected to the vertical moving frame 11 around its own axis, and the screw passes through the vertical moving platform 12 and is threadedly connected to the vertical moving platform 12. The motor is mounted on the vertical moving frame 11 and is used to drive the screw to rotate. Under the guidance of the vertical moving frame 11, the screw rotates and drives the vertical moving platform 12 to move vertically.

[0038] Reference Figure 2 and Figure 3 The vertical moving platform 12 is equipped with a horizontally arranged rotating shaft 2, which is parallel to the conveying roller 33. The rotating shaft 2 is rotatably connected to the vertical moving platform 12 around its own axis. The vertical moving platform 12 is equipped with a rotating component for driving the rotating shaft 2 to rotate. Specifically, the rotating component is also selected as a motor, and the motor is connected to the rotating shaft 2 through a reducer. When the motor works, it drives the rotating shaft 2 to rotate.

[0039] Reference Figure 2 and Figure 3 A rotating shaft 2 has multiple arc-shaped plates 21 evenly distributed along its circumference. All arc-shaped plates 21 are parallel to the rotating shaft 2, and a telescopic rod is installed between the arc-shaped plates 21 and the rotating shaft 2. The telescopic rod extends and retracts perpendicular to the rotating shaft 2. When the arc-shaped plates 21 move closer to or further away from the rotating shaft 2, they cause the telescopic rod to extend and retract. The rotating shaft 2 uses the telescopic rod to limit and guide the arc-shaped plates 21. The side of the arc-shaped plates 21 facing away from the rotating shaft 2 has an arc-shaped surface 211. When all the arc-shaped plates 21 reach their furthest point from the rotating shaft 2, all the arc-shaped surfaces 211 are coaxial.

[0040] Reference Figure 3 and Figure 4 The rotating shaft 2 is equipped with a pusher for moving the arc-shaped plate 21. The pusher includes two moving rings 221, which are sleeved on the outside of the rotating shaft 2 and slidably connected to the rotating shaft 2 axially. Multiple push rods 222, corresponding to the arc-shaped plates 21, are arranged circumferentially on the outside of the moving rings 221. One end of each push rod 222 is hinged to a moving ring 221, and the other end is hinged to an arc-shaped plate 21. Two push rods 222 are connected to the same arc-shaped plate 21. The push rods 222 remain in an inclined state. When the two moving rings 221 approach each other, the push rods 222 move the arc-shaped plate 21 away from the rotating shaft 2; when the two moving rings move away from each other, the push rods 222 move the arc-shaped plate 21 closer to the rotating shaft 2.

[0041] Reference Figure 3 and Figure 4 A positioning element 25 is provided on the movable ring 221. The positioning element 25 includes a mounting ring 251 and a positioning block 252. The mounting ring 251 is coaxially rotatably connected to the movable ring 221. When the movable ring 221 moves, it drives the mounting ring 251 to move synchronously. The positioning block 252 is fixedly connected to the mounting ring 251 and moves synchronously with the mounting ring 251. A straight groove 271 is formed on the outer circle of the rotating shaft 2 along the axial direction. When the two movable rings 221 are in a position away from each other, the positioning block 252 is located in the straight groove 271. The rotating shaft 2 also has an arc-shaped groove 272 that communicates with the straight groove 271 along the circumferential direction. The arc-shaped groove 272 is located at one end of the straight groove 271. When the two movable rings 221 are close to each other, the positioning block 252 is directly opposite the arc-shaped groove 272. When the mounting ring 251 rotates, it drives the positioning block 252 to switch between the straight groove 271 and the arc-shaped groove 272.

[0042] Reference Figure 3 and Figure 4 Multiple spacer plates 23 are arranged circumferentially on the outer side of the rotating shaft 2. The spacer plates 23 and the arc-shaped plates 21 are alternately arranged and parallel to each other. A telescopic rod 2 is also provided between the spacer plates 23 and the rotating shaft 2. The telescopic rod 2 extends and retracts in a direction perpendicular to the axis of the rotating shaft 2. The rotating shaft 2 limits and guides the spacer plates 23 through the telescopic rod 2, so as to guide the spacer plates 23 to move closer to or away from the rotating shaft 2. When all the arc-shaped plates 21 are in a position away from the rotating shaft 2, the gap between two adjacent arc-shaped plates 21 is adapted to the spacer plates 23. The side of the spacer plate 23 facing away from the rotating shaft 2 is provided with an arc-shaped surface 231. When the spacer plate 23 is between two arc-shaped plates 21, the arc-shaped surface 211 and the arc-shaped surface 231 are coaxial, and at this time all the arc-shaped plates 21 and the spacer plates 23 cooperate to form a complete ring structure.

[0043] Reference Figure 3 and Figure 4The rotating shaft 2 is provided with a second pusher for moving the partition plate 23. The second pusher includes two opposing moving rings 241. The moving rings 241 are sleeved on the outside of the rotating shaft 2 and are slidably connected to the rotating shaft 2 in the axial direction. Both movable rings 241 are located between two movable rings 221. Multiple push rods 242 corresponding to the spacer plate 23 are arranged circumferentially on the movable rings 241. One end of the push rod 242 is hinged to the movable rings 241 and the other end is hinged to the spacer plate 23. When the two movable rings 241 approach each other, the push rods 242 drive the spacer plate 23 away from the rotating shaft 2. When the two movable rings 241 move away from each other, the push rods 242 drive the spacer plate 23 closer to the rotating shaft 2. An elastic element 513 is provided between the movable plate and the movable rings 241. The elastic element 513 is a spring. One end of the spring is fixed to the rotating shaft 2 and the other end abuts against the movable rings 241. In the natural state of the elastic element 513, the two movable rings 241 move away from each other. At this time, the spacer plate 23 is in a position close to the rotating shaft 2.

[0044] Reference Figure 4 and Figure 5 The rotating shaft 2 is also equipped with a moving component, which is used to drive the first moving ring 221 and the second moving ring 241 to move in stages. The moving component includes two moving blocks 41 and a power component 42 (see reference). Figure 3 The system includes two rotating rings 43 and a rotating component. The rotating shaft 2 is hollow, and both moving blocks 41 are located inside the rotating shaft 2 and move along the length of the rotating shaft 2. The power component 42 (see reference) Figure 3 The power component 42 is used to move the moving block 41. Specifically, it can be an electric actuator or other driving mechanism. In this embodiment, the power component 42 (see reference) Figure 3 It includes a motor and a double-acting lead screw. The double-acting lead screw is set along the length of the rotating shaft 2 and is rotatably connected to the rotating shaft 2 around its own axis.

[0045] Reference Figure 3 and Figure 5 Two movable blocks 41 are located at the two ends of the bidirectional lead screw, and the bidirectional lead screw passes through the movable blocks 41 and is threadedly connected to the movable blocks 41. The second motor is installed at one end of the rotating shaft 2 to drive the bidirectional lead screw to rotate. Under the guidance of the rotating shaft 2, the bidirectional lead screw rotates and drives the two movable blocks 41 to move closer or further apart. An opening is provided on the outer side of the rotating shaft 2 along the axial direction, and one side of the movable block 41 passes through the opening and extends to the outer side of the rotating shaft 2.

[0046] Reference Figure 4 and Figure 5 The rotating ring 43 is located between the first moving ring 221 and the second moving ring 241. The rotating ring 43 is sleeved on the outside of the rotating shaft 2 and rotates around its own axis and is connected to the moving block 41. When the moving block 41 moves, it drives the rotating ring 43 to move along the rotating shaft 2.

[0047] Reference Figure 5 and Figure 6 A hook 431 is fixedly connected to the side of the rotating ring 43 near the moving ring 221. The moving ring 221 is provided with a hooking part 223 adapted to the hook 431. The hooking part 223 is specifically a recessed groove. The inner side of the groove extends along the circumference of the moving ring. When the hook 431 is located in the groove, the rotating ring 43 rotates around its own axis, causing the hook 431 to engage or disengage from the moving ring 221. When the hook 431 engages with the moving ring 221 through the hooking part 223, the rotating ring 43 moves along the axial direction, causing the moving ring 221 to move synchronously.

[0048] Reference Figure 4 and Figure 7 A connecting ring is rotatably connected to the end of the rotating shaft 2 away from the motor 441. The connecting ring is coaxial with the rotating shaft 2. An adjusting rod 52 is fixed between the two connecting rings. The adjusting rod 52 is set along the axial direction of the rotating shaft 2 and passes through the mounting ring 251 and the rotating ring 43 in sequence along the axial direction, and is slidably connected to both. When the connecting ring rotates, it drives the mounting ring 251 and the rotating ring 43 to rotate through the adjusting rod 52. The first moving ring 221 and the second moving ring 241 are both circumferentially open with arc-shaped openings. The adjusting rod 52 passes through the arc-shaped openings of the first moving ring 221 and the second moving ring 241. When the connecting ring rotates, the adjusting rod 52 does not contact the first moving ring or the second moving ring 241.

[0049] Reference Figure 4 and Figure 7 The connecting ring includes a positioning ring 511, a contact ring 512, and an elastic element 513. The positioning ring 511 rotates coaxially with the rotating shaft 2. The contact ring 512 is located at the end of the positioning ring 511 away from the motor and is slidably connected to the positioning ring 511 along the axial direction. The contact ring 512 is coaxial with the positioning ring 511. When the contact ring 512 rotates, it drives the positioning ring 511 to rotate synchronously. The elastic element 513 is a spring. The spring is located between the positioning ring 511 and the contact ring 512 and pushes the contact ring 512 away from the positioning ring 511 in its natural state.

[0050] Reference Figure 4 and Figure 7 Two limiting grooves 261 are formed on the outer surface of the rotating shaft 2 along the axial direction. The two limiting grooves 261 are distributed around the circumference of the rotating shaft 2, and a through groove 262 is connected between the two limiting grooves 261. The through groove 262 is located at the end of the limiting groove 261 closer to the motor. The contact ring 512 is fixedly connected to a limiting block 515 corresponding to the limiting groove 261. In the natural state of the elastic element 513, the limiting block 515 is inserted into any limiting groove 261 and fits against the inner wall of the limiting groove 261. At this time, the rotating shaft 2 limits the rotation of the contact ring 512 around the circumference through the limiting block 515, thereby positioning the adjusting rod 52.

[0051] Reference Figure 2 and Figure 7 The rotating components include a motor 441, a translation frame 442, and a transmission ring 443. A support frame 13 is fixed to the upper end of the vertical translation frame 11, extending to the end of the rotating shaft 2 away from the motor 2. The translation frame 442 is slidably connected to the vertical translation frame 11 along the axis of the rotating shaft 2. A cylinder for moving the translation frame 442 is mounted on the support frame 13. A positioning shaft 445 is fixedly connected to the end of the translation frame 442 near the rotating shaft 2. The positioning shaft 445 is parallel to the rotating shaft 2, and its radial cross-section is polygonal. When the rotating shaft 2 moves upward with the vertical translation platform 12 to its maximum displacement, it is coaxial with the positioning shaft 445. A polygonal hole 28 adapted to the positioning shaft 445 is provided at the end of the rotating shaft 2 away from the motor 2.

[0052] Reference Figure 3 and Figure 4 The transmission ring 443 is located outside the positioning shaft 445 and is rotatably connected to the translation frame 442. The positioning shaft 445 is parallel to the transmission ring 443. The motor 441 is mounted on the translation frame 442 to drive the transmission ring 443 to rotate. A connecting block 514 is fixedly connected to the side of the contact ring 512 away from the positioning ring 511. A slot 444 adapted to the limiting block 515 is opened on the side of the transmission ring 443 near the rotating shaft 2. When the connecting block 514 is inserted into the slot 444, the transmission ring 443 drives the contact ring 512 to rotate during rotation.

[0053] The implementation principle of a tire tread winding machine according to an embodiment of this application is as follows: In the initial state, the vertical moving platform 12 is located below the vertical moving frame 11, the arc plate 21 and the spacer plate 23 are both located close to the rotating shaft 2, and at this time the spacer plate 23 is located between the arc plate 21 and the rotating shaft 2, and there is an active gap between the moving ring 221 and the moving ring 241. At this time, the hook 431 of the rotating ring 43 is engaged with the hook part 223 of the moving ring 221, and the vertical moving platform 12 moves up until the rotating shaft 2 and the positioning shaft 445 are coaxial. The manipulating frame 442 moves close to the rotating shaft 2, so that the positioning shaft 445 is inserted into the limiting hole, thereby restricting the rotation of the rotating shaft 2 around its own axis. The frame 442 continues to move, so that the transmission ring 443 moves close to the contact ring 512, until the connecting block 514 is inserted into the slot 444. When the transmission ring 443 pushes the contact ring 512 close to the positioning ring 511, the contact ring 512 drives the limiting block 515 to move out of the corresponding limiting groove 261 and into the through groove 262.

[0054] The power unit 42 is activated, and through the moving block 41, it drives the rotating ring 43 to move closer to the second moving ring 241 along the axial direction. When the rotating ring 43 moves, it drives the first moving ring 221 to move synchronously through the hook 431. When the first moving ring 221 moves, it drives the positioning block 252 to move along the straight groove 271 to the arc groove 272 through the mounting ring 251. When the first moving ring 221 moves, it drives the arc plate 21 to support the rubber part. When the first moving ring 221 moves to the preset position, the arc plate 21 reaches the maximum open state, at which time all the arc surfaces 211 are coaxial. Motor 441 drives transmission ring 443 to rotate, which in turn drives positioning ring 511 to rotate via contact ring 512, and drives rotating ring 43 and mounting ring 251 to rotate via adjusting rod 52. When mounting ring 251 drives positioning block 252 from straight groove 271 into arc groove 272, hook 431 of rotating ring 43 separates from hanging part 223, and at this time, limiting block 515 on contact ring 512 moves along through groove 262 to another limiting groove 261.

[0055] After the hook 431 separates from the hook part 223, the positioning block 252 is located in the arc groove 272, and the moving ring 221 is in a positioning state. The power component 42 continues to drive the moving block 41 to approach the moving ring 241 until the rotating ring 43 contacts the moving ring 241 and pushes the two moving rings 241 closer to each other. When the moving ring 241 moves, it drives the spacer 23 to move into the gap between the two adjacent arc plates 21 until the spacer 23 fills the gap between the two arc plates 21 and supports the rubber part through the arc surface 231. At this time, the spacer 23 and the arc plate 21 cooperate to form a complete ring, so that the rubber part is evenly spread. The translation frame 442 is reset, causing the positioning shaft 445 to disengage from the polygonal hole 28 and the transmission ring 443 to separate from the contact ring 512. At this time, the contact ring 512 moves away from the positioning ring 511 under the action of the elastic element 513, so that the limiting block 515 is inserted into another limiting groove 261, thereby limiting the rotation of the rotating ring 43 and the mounting ring 251 through the positioning ring 511 and the adjusting rod 52.

[0056] The fabric is sequentially wrapped around the conveyor roller 33 and the heating roller 34 and adhered to the outside of the rubber component. At this point, the pressing frame 36 drives the pressure roller 35 closer to the rubber component, pressing the fabric tightly onto it. The motor 2 drives the rotating shaft 2 to rotate, causing the rubber component to rotate and gradually wrapping the fabric around its outside. During the wrapping process, the manipulating frame 32 moves back and forth along the axis of the rotating shaft 2, ensuring the fabric is evenly wrapped around the rubber component. The arc-shaped plate 21 and the spacer plate 23 cooperate to form a complete annular support structure, which evenly spreads the rubber component along the annulus, thus improving the uniformity and tightness of the fabric wrapping.

[0057] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
