Description

Technical Field

[0001] This invention relates to the field of tire wire bead positioning technology, specifically to an automatic tire wire bead positioning device and method. Background Technology

[0002] Steel wire rings are the core rigid skeleton structure of a tire. Suitable steel wire rings are required for the tire bead and tread. Among them, the belt layer steel wire ring at the tread is formed by continuously winding a single high-strength copper-plated steel wire around the circumference of the tread to form a jointless ring structure. The positioning of the steel wire during the winding process is a key process in the preparation of tire steel wire rings. The existing method for preparing belt-layer steel wire rings generally involves continuously winding a single steel wire from one side of the tire crown to the other to form a ring. After being wound and formed, the steel wire ring is placed on the outside of the tire body and then bonded to the rubber after vulcanization. Although existing winding methods for belt layer steel wire rings can position the steel wires during the winding process using fixed guide wheels or concave wheels, the movement of a single steel wire from one side of the tire crown to the other can cause lateral deviation of the steel wire during transportation, resulting in gaps between adjacent steel wires. Excessive gaps can affect the overall forming effect of the belt layer steel wire ring.

[0003] To address the aforementioned problems, the inventors have proposed an automatic tire wire bead positioning device and method. Summary of the Invention

[0014] A method for using an automatic tire wire bead positioning device includes the following steps: Step 1: One end of the steel wire is wrapped around the outer wall of the wheel-type inner support mechanism through an immersion coating mechanism, and the tire belt layer is fitted onto the outer wall of the wheel-type inner support mechanism. The water-based adhesive lubricant is a low-viscosity water-based liquid. Step two: Rotate the wheel-type inner support mechanism to allow the steel wire to wrap around the outer wall of the tire belt layer, forming a steel wire loop; Step 3: During the winding process, the water-based adhesive lubricant keeps the steel wires attached to the outer wall of the tire belt layer. Under the rolling positioning of the rolling positioning mechanism, the attachment is tight, and multiple steel wire loops are kept in contact. Step four: During the frictional rotation between the roller and the steel wire, the fan blades are driven to rotate, and a small airflow blows the surface of the steel wire through the air outlet to prevent the water-based adhesive lubricant from accumulating on the outer wall of the steel wire.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention uses a tension spring to provide tension to the swing arm. The roller and positioning pressure roller are always in close contact with the winding steel wire. The roller, in conjunction with the texture of the roller wall, increases the contact friction with the steel wire. The roller performs real-time rolling and positioning of the steel wire. During the winding process, the positioning pressure roller pushes the steel wire towards the disc to prevent the steel wire from deviating laterally and to tightly press adjacent steel wires together, avoiding gaps. This ensures the uniformity and density of the steel wire coil arrangement and improves the positioning effect.

[0016] 2. The immersion coating mechanism of the present invention can uniformly coat the outer wall of the steel wire with a water-based adhesive lubricant. The weak adhesion of the lubricant allows the steel wire to quickly adhere to the uncured tire belt layer, thereby avoiding the problems of collapse and lifting during the winding process of the steel wire.

[0017] 3. When the roller of the present invention rotates in friction with the steel wire, it synchronously drives the internal fan blades to rotate and generate micro airflow. The airflow is blown directionally to the surface of the steel wire through the air outlet, which can blow away excess water-based adhesive lubricant on the outer wall of the steel wire, prevent the lubricant from accumulating locally in the belt layer, and ensure the uniformity of the lubricant.

[0029] 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 skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] like Figure 1 - Figure 9 As shown, the present invention provides an automatic tire wire bead positioning device, including a frame 1, a winding and unwinding mechanism 2 and a wire 3. The winding and unwinding mechanism 2 is mounted on the frame 1, and the wire 3 is wound around the feeding section of the winding and unwinding mechanism 2. One end of the frame 1 is fixedly connected to a guide rod 11. An immersion coating mechanism 4 is slidably connected to the outer wall of the guide rod 11. The steel wire 3 passes through the immersion coating mechanism 4 and is slidably connected. The immersion coating mechanism 4 applies a water-based adhesive lubricant to the outer wall of the steel wire 3. One end of the frame 1 is rotatably connected to a wheel-type inner support mechanism 5. A tire belt layer 9 is fitted on the outer wall of the wheel-type inner support mechanism 5. The steel wire 3 is attached to the outer wall of the tire belt layer 9 by a water-based adhesive lubricant. A disc 7 is rotatably connected to and fitted on the outer wall of the wheel-type inner support mechanism 5. The disc 7 is fixedly connected to the frame 1. A roller pressing positioning mechanism 6 is provided on the disc 7. The wheel-type inner support mechanism 5 drives the tire belt layer 9 to rotate, and the steel wire 3 is wound on the outer wall of the tire belt layer 9. The roller pressing and positioning mechanism 6 performs roller pressing and positioning on the steel wire 3 during the winding process.

[0031] Combination Figure 1 As shown, the winding and unwinding mechanism 2 includes a drive motor 22 and a material conveying section. The material conveying section is composed of a winding rotating frame 21, which is rotatably connected to one end of the frame 1. The drive motor 22 is mounted on the outer wall of the frame 1, and the output end of the drive motor 22 is connected to the winding rotating frame 21. The steel wire 3 is wound on the outer wall of the winding rotating frame 21. The purpose of this setup is to drive the motor 22 to rotate the winding rotating frame 21 and unwind the steel wire 3.

[0032] Combination Figure 3 As shown, the immersion coating mechanism 4 includes a sliding guide block 41, a liquid storage box 42, and a rotating outer ring 43. The bottom of the sliding guide block 41 has two through holes 410, and the sliding guide block 41 is slidably connected to the outer wall of the guide rod 11 through the through holes 410. The height of the guide rod 11 is higher than that of the wheel-type inner support mechanism 5 and the winding and unwinding mechanism 2, respectively. The sliding guide block 41 is provided with a guide groove 412, and the steel wire 3 is slidably connected to the arc-shaped inner wall of the guide groove 412. The purpose of this arrangement is to guide the steel wire 3 along the arc-shaped inner wall of the guide groove 412. When a single steel wire 3 moves from one side of the tire belt layer 9 to the other side, it drives the sliding guide block 41 to move on the guide rod 11, thereby adapting to its movement process.

[0033] Combination Figure 3 As shown, the liquid storage box 42 is located on top of the sliding guide block 41. An inlet is provided on the outer wall of the liquid storage box 42. A rotating outer ring 43 is rotatably connected to the outer wall of the liquid storage box 42. Several drain holes 430 are provided on the rotating outer ring 43. A gap is left between the rotating outer ring 43 and the guide groove 412. An outlet is provided at the bottom of the liquid storage box 42. Grooves 431 are provided on the outer wall of the rotating outer ring 43. The bottom of the sliding guide block 41 is provided with an inner cavity 411, and a number of output ports 414 are provided on the inner cavity 411. The inner wall of the guide groove 412 is provided with a discharge port 413, which leads to the interior of the inner cavity 411. The purpose of this arrangement is that when the steel wire 3 passes between the guide groove 412 and the rotating outer ring 43, it rubs against the groove 431, causing the rotating outer ring 43 to rotate. When the drain hole 430 of the rotating outer ring 43 aligns with the outlet at the bottom of the liquid storage box 42, the water-based adhesive lubricant is discharged and applied to the steel wire 3 to reduce the friction between the steel wire 3 and the guide groove 412. The excess water-based adhesive lubricant flows from the discharge port 413 to the inner cavity 411, and then flows through the output port 414 to the guide rod 11, reducing frictional resistance.

[0034] Combination Figure 4 - Figure 5 As shown, the wheeled internal support mechanism 5 includes a servo motor 51 and an arc-shaped support block 59. The servo motor 51 is mounted on the outer wall of one end of the frame 1. A connecting shaft 52 is connected to the output shaft of the servo motor 51. Several bottom rods 57 are fixedly connected to the middle of the connecting shaft 52. A sliding frame 58 is slidably connected to the bottom rods 57. An arc-shaped support block 59 is fixedly connected to one end of the sliding frame 58. The outer wall of the connecting shaft 52 is provided with threads, and a rotating screw ring 54 is threadedly connected to the outer wall of the threaded connecting shaft 52. A sliding connecting block 55 is rotatably connected to the outer wall of the rotating screw ring 54. Several connecting arms 56 are rotatably connected to the outer wall of the sliding connecting block 55. One end of the connecting arm 56 is rotatably connected to the outer wall of the sliding frame 58. The purpose of this arrangement is to rotate the rotating ring 54 on the outer wall of the rotating connecting shaft 52, move the rotating ring 54 along the thread of the rotating connecting shaft 52, slide the sliding connecting block 55 on the rotating connecting shaft 52, drive the connecting arm 56 to swing through the sliding connecting block 55, push the sliding frame 58 to slide along the bottom rod 57, thereby adjusting the opening range of the arc-shaped support block 59 until the arc-shaped support block 59 can form an internal support and fix the tire belt layer 9, and then put the tire belt layer 9 onto the outer wall of the arc-shaped support block 59 to complete the clamping of the tire belt layer 9.

[0035] Combination Figure 5 As shown, a convex ring is provided at one end of the connecting shaft 52, and a first spring 53 is sleeved on the outer wall of the connecting shaft 52. The first spring 53 is located between the convex ring and the rotating screw ring 54. The purpose of this arrangement is to keep the first spring 53 taut and prevent the rotating screw ring 54 from loosening and causing accidental rotation.

[0036] Combination Figure 6 As shown, the roller positioning mechanism 6 includes a swing arm 61, a tension spring 62, and a roller 63. The swing arm 61 is rotatably connected to the outer wall of the disc 7. One end of the tension spring 62 is rotatably connected to the outer wall of the swing arm 61, and the other end of the tension spring 62 is rotatably connected to the outer wall of the disc 7. The roller 63 is rotatably connected to one end of the swing arm 61, and a plurality of cylinder wall textures 631 are provided on the outer wall of the roller 63. The purpose of this arrangement is that when the tire belt layer 9 rotates and winds the steel wire 3, the tension spring 62 provides continuous tension to the swing arm 61, so that the roller 63 at the end of the swing arm 61 is always in close contact with the outer wall of the wound steel wire 3, and the roller 63 rotates synchronously with the movement of the steel wire 3 and the rotation of the tire belt layer 9. The texture 631 on the outer wall of the roller 63 increases the contact friction with the steel wire, which not only prevents the steel wire from deviating laterally during winding, but also tightly presses the steel wire 3 onto the outer wall of the tire belt layer 9.

[0037] Combination Figure 7 and Figure 8 As shown, a sliding block 67 is slidably connected to the inner wall of the roller 63, and a connecting frame 69 is fixedly connected to the outer wall of the sliding block 67. The connecting frame 69 is slidably connected to the roller 63 and extends to the outside. A second spring 8 is provided between the sliding block 67 and the inner wall of the roller 63. An arc-shaped block 691 is connected to one end of the sliding block 67. A slot frame 692 is provided on the outer wall of the connecting frame 69, a sliding rod 694 is slidably connected on the inner wall of the slot frame 692, a third spring 693 is provided on the inner wall of the slot frame 692, and a positioning pressure wheel 695 is rotatably connected to one end of the sliding rod 694. The positioning pressure wheel 695 is provided with a circular wheel arc surface trapezoidal platform. The purpose of this setting is that when the steel wire 3 has a slight positional shift, the positioning pressure roller 695 on the outer side of the roller 63 adaptively presses against the steel wire 3 by the elastic force of the third spring 693. The positioning pressure roller 695 is provided with a circular arc-shaped trapezoidal platform, whose close end face fits the outer side of the steel wire 3, pressing the steel wire 3 against the disc 7, so that the steel wire loops formed by the winding of the steel wire 3 are tightly pressed together.

[0038] Combination Figure 6 - Figure 9 As shown, one end of the swing arm 61 is provided with an air inlet, which extends into the interior of the roller 63. A guide rod 68 is fixedly connected to the inner wall of the roller 63. A toothed ring 64 is rotatably connected to the outer wall of the sliding block 67. The toothed ring 64 is slidably connected to the guide rod 68. A gear 65 is rotatably connected to the inner wall of the toothed ring 64. A slot is opened on the outer wall of the gear 65. A fan blade 66 is connected to the axle of the gear 65. An arc-shaped hole is provided between the toothed ring 64 and the sliding block 67. Several air outlets 630 are opened on the outer wall of the roller 63. The purpose of this arrangement is that during the frictional rotation of the roller 63 and the steel wire 3, the guide rod 68 drives the toothed ring 64 to rotate synchronously. When the steel wire 3 is wound outward, the connecting frame 69 and the toothed ring 64 slide synchronously with the guide rod 68. The toothed ring 64 and the sliding block 67 rotate relative to each other. The toothed ring 64 drives the gear 65 and the fan blade 66 to rotate. The micro-airflow generated by the rotation of the fan blade 66 is blown directionally to the surface of the steel wire 3 through several air outlets 630 on the outer wall of the roller 63. On the one hand, the micro-airflow can blow away the excess water-based adhesive lubricant on the outer wall of the steel wire 3, preventing the lubricant from accumulating on the surface of the steel wire 3 and ensuring the uniformity of the lubricant film; On the other hand, the micro-airflow can quickly remove the local heat generated by the friction between the steel wire 3 and the roller 63 and the tire belt layer 9 during the winding process.

[0039] A method for using an automatic tire wire bead positioning device includes the following steps: Step 1: One end of the steel wire 3 is wrapped around the outer wall of the wheel-type inner support mechanism 5 through the immersion coating mechanism 4, and the tire belt layer 9 is fitted on the outer wall of the wheel-type inner support mechanism 5. The water-based adhesive lubricant is a low-viscosity water-based liquid. Step 2: The wheel-type inner support mechanism 5 is rotated to allow the steel wire 3 to wrap around the outer wall of the tire belt layer 9, forming a steel wire loop; Step 3: During the winding process, the water-based adhesive lubricant keeps the steel wire 3 attached to the outer wall of the tire belt layer 9. Under the rolling positioning of the roller positioning mechanism 6, the attachment is tight, and at the same time, multiple steel wire loops are kept in contact. Step four: During the frictional rotation between the roller 63 and the steel wire 3, the fan blade 66 is driven to rotate. A small airflow blows the surface of the steel wire 3 through the air outlet 630 to prevent the water-based adhesive lubricant from accumulating on the outer wall of the steel wire 3.

[0040] Working principle: First, according to the inner diameter of the tire belt layer 9 to be processed, rotate the rotating screw ring 54 on the outer wall of the connecting shaft 52. The rotating screw ring 54 moves along the thread of the rotating connecting shaft 52, and the sliding connecting block 55 slides on the rotating connecting shaft 52. The sliding connecting block 55 drives the connecting arm 56 to swing, and the connecting arm 56 pushes the sliding frame 58 to slide along the bottom rod 57, thereby adjusting the opening range of the arc-shaped support block 59 until the arc-shaped support block 59 can form an internal support and fix the tire belt layer 9. Then, the tire belt layer 9 is sleeved onto the outer wall of the arc-shaped support block 59 to complete the clamping of the tire belt layer 9.

[0041] Simultaneously, one end of the steel wire 3 is led out from the winding rotating frame 21 and passes through the guide groove 412 of the immersion coating mechanism 4, so that the steel wire 3 fits against the arc-shaped inner wall of the guide groove 412. Finally, the head end of the steel wire 3 is fixed to the outer wall of the arc-shaped support block 59 of the wheel-type inner support mechanism 5, completing the initial positioning of the steel wire. At this time, water-based adhesive lubricant can be added through the inlet of the liquid storage box 42. The lubricant flows into the inner cavity 411 through the bottom outlet of the liquid storage box 42, and then seeps into the guide groove 412 through the discharge port 413 to achieve immersion coating on the outer wall of the steel wire 3.

[0042] Start the drive motor 22 and the servo motor 51 of the wheel-type inner support mechanism 5. The drive motor 22 drives the winding rotating frame 21 to rotate, realizing the synchronous unwinding of the steel wire 3. The servo motor 51 drives the connecting shaft 52 and the arc-shaped support block 59 to rotate at a uniform speed, thereby driving the tire belt layer 9 to rotate synchronously. As the belt layer rotates, the steel wire 3 continuously winds around its outer wall, gradually forming a belt layer steel wire ring.

[0043] During the winding process, the immersion coating mechanism 4 continuously coats the outer wall of the steel wire 3 with water-based adhesive lubricant: when the steel wire 3 slides in the guide groove 412, it comes into full contact with the inner wall of the groove which is wetted with lubricant, so as to achieve uniform coating of lubricant. The outer ring 43 can be manually adjusted via the groove 431 to control the liquid output from the drain hole 430. This, combined with the output port 414 of the inner cavity 411, precisely controls the amount of lubricant applied, ensuring that only a thin liquid film forms on the surface of the steel wire. This satisfies both adhesion and lubrication requirements while avoiding over-coating. Simultaneously, the immersion coating mechanism 4 can slide along the guide rod 11, adapting to fine-tuning of its position during the wire winding process and ensuring continuous coating.

[0044] When the tire belt layer 9 rotates and winds the steel wire 3, the tension spring 62 provides a continuous tension to the swing arm 61, so that the roller 63 at the end of the swing arm 61 is always in close contact with the outer wall of the wound steel wire 3. The roller 63 rotates synchronously with the movement of the steel wire 3 and the rotation of the tire belt layer 9. The texture 631 on the outer wall of the roller 63 increases the contact friction with the steel wire, which not only prevents the steel wire from deviating laterally during winding, but also tightly presses the steel wire 3 onto the outer wall of the tire belt layer 9.

[0045] When the steel wire 3 is slightly misaligned, the positioning pressure roller 695 on the outside of the roller 63 adaptively presses against the steel wire through the elastic force of the third spring 693. The circular arc surface trapezoidal platform structure of the positioning pressure roller 695 performs secondary positioning on the steel wire 3, quickly returning the misaligned steel wire 3 to the predetermined winding trajectory, further improving positioning. The sliding block 67 can slide along the inner wall of the roller 63. With the buffering effect of the second spring 8, the roller 63 and the positioning pressure roller 695 adapt to the winding arc of the steel wire 3, avoiding hard contact that could damage the steel wire 3.

[0046] During the frictional rotation of the roller 63 and the steel wire 3, the guide rod 68 drives the toothed ring 64 to rotate synchronously. When the steel wire 3 is wound outward, the connecting frame 69 and the toothed ring 64 slide synchronously with the guide rod 68. The toothed ring 64 and the sliding block 67 rotate relative to each other. The toothed ring 64 drives the gear 65 and the fan blade 66 to rotate. The micro-airflow generated by the rotation of the fan blade 66 is blown directionally to the surface of the steel wire 3 through several air outlets 630 on the outer wall of the roller 63.

[0047] After the steel wire 3 is wound around the outer wall of the tire belt layer 9 to form a steel wire ring of predetermined specifications, the drive motor 22 and the servo motor 51 are turned off, the steel wire 3 is cut off, and each mechanism is reset to complete a complete winding and positioning of the steel wire ring in the tire belt layer 9.

[0048] All standard mechanical parts used in this invention can be purchased commercially, and irregularly shaped parts can be custom-made according to the description and drawings. The specific mechanical connection methods for each part can employ conventional methods such as bolts, rivets, and welding, which are already well-established in the prior art.
