Description

Technical Field

[0001] This invention relates to the field of tire processing technology, and in particular to a steel cord straightening device. Background Technology

[0002] Steel cord is commonly used in tire manufacturing. As the tire skeleton, steel cord must be kept in a straight line to ensure the tire's radial strength, uniformity, and high-speed stability, thereby improving tensile strength and fatigue resistance. However, during the production process, steel cord may be wound or coiled. If it remains bent, it may affect subsequent processing, such as its arrangement within the tire, leading to uneven stress and affecting the tire's strength and durability. Therefore, a straightening process is required for the steel cord. After straightening, the steel cord can distribute the load evenly under stress, avoiding localized stress concentration caused by bending, thereby improving tensile strength and fatigue resistance. Traditional straightening equipment mostly uses clamps to fix one end of the steel cord to ensure it is secure and does not slip. Then, appropriate tension is applied to the other end of the steel cord. However, this straightening method still has many problems in use: First, after the steel cord is straightened, the tension cannot be released immediately. It needs to be clamped for a period of time to maintain the straightness of the steel cord, but this is time-consuming and inefficient. Second, the rolled steel cord is long, so it can only be straightened section by section. However, the applied tension is not easy to control. At best, it will not straighten, and at worst, it will damage the rigidity of the steel cord. Third, the bending angle of the steel cord is different during the laying process. It is difficult to restore it to a straight state by simply straightening it, resulting in poor straightening effect. Summary of the Invention

[0003] To overcome the shortcomings of existing technologies, this invention provides a steel cord straightening device with a reasonable structural design and convenient use. It can continuously straighten steel cords and apply force to the steel cords at different angles and positions during the straightening process, allowing the steel cords to quickly return to a straight state with good straightening effect. It eliminates the need for long waiting times, saving time and effort and improving work efficiency. Furthermore, the applied tension has a gradual release effect, preventing damage to the steel cords. It can straighten steel cords without compromising their rigidity, thus solving many problems existing in the prior art.

An offset motor 40 connected to the screw 39 is provided on the outer wall of one of the partitions 37. A battery compartment 41 is provided on the partition 37 below the offset motor 40. A guide rod 42 is horizontally arranged below the screw 39. The guide rod 42 movably passes through the offset block 38 and is connected to the corresponding partition 37. A pull hole 43 is provided in the center of the offset block 38 between the guide rod 42 and the screw 39.

[0035] Optionally, the drive assembly includes a transmission channel 44 formed on the front side of the annular guide rail 31. The bottom end of the transmission channel 44 abuts against the surface of the movable seat 4 and communicates with the first groove 32. A transmission gear 45 is provided on the movable seat 4 on one side corresponding to the transmission channel 44. The transmission gear 45 extends into the transmission channel 44 and meshes with the tooth groove 36 on the gear ring 35. The transmission gear 45 is fixed to the movable seat 4 by gear clamps 46 provided on its left and right sides. Its rotating shaft moves through the right gear clamp 46 and slides upward. The upper pulley 47 is connected to the lower pulley 47 by a pulley clamp 48 on its right side. A motor groove 49 is horizontally provided in the movable seat 4 on the side corresponding to the transmission gear 45. A belt channel 50 connected to the motor groove 49 is vertically provided on the surface of the movable seat 4 at the position corresponding to the upper pulley 47. A transmission motor 51 is provided in the motor groove 49, and its output shaft is connected to the lower pulley 52. ​​The lower pulley 52 is located directly below the upper pulley 47. A belt 53 is wound around the upper pulley 47 and the lower pulley 52.

[0036] Optionally, buffer sleeves 54 are provided in both the inlet hole 3 and the pull hole 43, with the left and right ends of the buffer sleeves 54 being flared. The buffer sleeves 54 can reduce friction with the steel cord and reduce the risk of damaging the steel cord.

[0037] Before use, the steel cord is first fed into the first through slot 16 of the buffer mechanism and then into the inlet hole of the left support plate 2. After passing through the pull hole 43 of the offset block 38, it exits outward from the second through slot 22 of the right support plate 2. During use, the first cylinder 20 and the second cylinder 26 are activated respectively. The piston rod of the first cylinder 20 pushes the first slider 18 outward, causing the first slider 18 to move inward along the first limiting slot 17 on the corresponding side of the first limiting block 19 on both sides, thus pushing the steel cord into the first snap-fit ​​hole 21 and clamping the steel cord by the first slider 18. The piston rod of the second cylinder 26 pushes the second slider 24 outward, causing the second slider 24 to move downward along the second limiting slot 23 on the corresponding side of the second limiting block 25 on both sides, thus pushing the steel cord into the second snap-fit ​​hole 27 and clamping the steel cord by the second slider 24. Then, the offset motor 40 is started, and the battery in the battery compartment 41 powers the offset motor 40, causing it to move the offset block 38 via the screw 39, thereby pulling the steel cord to a taut state. At the same time, the drive motor 51 starts, and its output shaft drives the lower pulley 52 to rotate, which in turn transmits power to the upper pulley 47 via the belt 53, causing the drive gear 45 to rotate. As the drive gear 45 rotates, it drives the rotating ring 33 to rotate within the first groove 32 of the annular guide rail 31 through the toothed grooves 36 on the gear ring 35, thus causing the steel cord to make a circular motion through the offset block 38. To improve the straightening effect, the offset block 38 can be moved further outward, thereby increasing the rotation radius of the steel cord. As the tension increases, it can be released through the buffer mechanism to avoid damaging the steel cord. After the steel cord is under force, the first slider 18 pulls the steel cord and the buffer plate 9, causing it to flip to the right along the hinge position through the two hinge blocks 10. The two buffer cylinders 12 provide resistance to the buffer plate 9, keeping the steel cord taut. The air supply mechanism, via the compressor 14, injects air into the air tank 15, providing a constant air supply to the buffer cylinders 12 to maintain resistance. To further improve the straightening effect, the two transverse cylinders 29 can be activated, causing the moving seat 4 to move left and right, contacting different positions of the steel cord. The moving seat 4 then slides along the slide rail 6 within the corresponding slide rail 5. After the straightening process is completed, the infeed and outfeed fixing mechanisms are released, and the steel cord is pulled to allow the next section of steel cord to enter. Its structure is reasonable and easy to use. It can continuously straighten steel cords. During the straightening process, force can be applied to the steel cords at different angles and positions, so that the steel cords can quickly return to a straight state. The straightening effect is good, and there is no need to wait for a long time, which saves time and effort and improves work efficiency. Moreover, the applied tension has a slow release effect and will not damage the steel cords. It can straighten the steel cords without destroying their rigidity, thus solving many problems existing in the prior art.
