Description

Technical Field

[0001] This utility model relates to the technical field of giant tire production equipment, and in particular to a giant tire reverse wrapping device. Background Technology

[0002] The structure of a giant tire forming machine is a traditional four-drum, two-end method, although a two-drum, one-stage method is also available. It typically uses a tire carcass transfer ring to transfer the rubber components, resulting in unstable production processes, difficulty in bladder reversal, and inconsistent tire carcass forming quality. Currently, there are two main methods for reversing the tire carcass of giant tires: the first uses a finger rod for reversal; the second uses a combination of a bladder and a bead-locking device for reversal. The latter method is more efficient than the finger rod method.

[0003] The existing technology has at least the following problems: First, the reverse wrapping of the finger rod is time-consuming and laborious, and the reverse wrapping effect is not ideal. The reverse wrapping of one side takes about 30 minutes and requires the operator to be experienced. Second, the bead fastener can only push the tire carcass cord to the bead position, and the final reverse wrapping still requires manual intervention. The operation cannot be fully automated. Utility Model Content

[0004] This invention addresses the shortcomings of existing technologies by developing a giant tire reversing device. This invention can perform complete reversing while reducing manual intervention, effectively improving the reversing effect and efficiency.

[0005] The technical solution of this utility model to solve the technical problem is as follows: a giant tire reverse wrapping device, including a first main unit and a second main unit, and also including two sets of wall plates and two sets of propulsion covers. A main shaft is provided between the first main unit and the second main unit. Several sets of first telescopic devices are provided on both the first main unit and the second main unit. The output end of the first telescopic device is connected to one side of the wall plate. The wall plate is slidably mounted on the main shaft. Several sets of second telescopic devices are provided on one side of the wall plate. The output end of the second telescopic device is connected to one side of the propulsion cover. The propulsion cover is slidably mounted on the wall plate through a guide assembly.

[0006] As an optimization, both the first and second main units are equipped with several sets of guide seats, and several sets of first guide rods are correspondingly provided on one side of the wall panel. The first guide rods are slidably disposed within the guide seats. By setting the guide seats and first guide rods, firstly, they can cooperate with the main shaft to provide guidance for the movement of the wall panel, improving the stability of the wall panel's movement; secondly, they can support the wall panel and the propulsion cover, reducing the pressure on the main shaft.

[0007] As an optimization, the propulsion shroud includes a base plate, a cylinder, and a shroud body. The base plate is annular, with its outer edge connected to one end of the shroud body via the cylinder. The inner edge of the base plate is connected to the other end of the shroud body. The shroud body is cylindrical, with one end having a larger diameter than the other. By using the base plate and cylinder, the shroud body can be supported during the inversion process, ensuring its strength, preventing deformation, and guaranteeing the inversion effect. Furthermore, by designing the shroud body with an inclined inner surface, the capsule can be better propelled during the inversion process, further ensuring the inversion effect.

[0008] As an optimization, the guiding assembly includes several sets of guide sleeves and several sets of second guide rods. The guide sleeves are evenly distributed on one side of the wall panel, and the second guide rods are correspondingly disposed on the base plate, slidingly disposed within the guide sleeves. By setting the guide sleeves and second guide rods, the axial movement of the propulsion cover can be guided, preventing deviation, and also providing auxiliary support for the propulsion cover.

[0009] As an optimization, a base is also included, on which a first slide rail is provided. A first support is provided at the bottom of the propulsion shroud, and a first pulley is provided at the bottom of the first support. The first pulley is slidably mounted on the first slide rail. By setting up the base, the first slide rail, the first support, and the first pulley, the movement of the propulsion shroud can be supported, ensuring that the propulsion shroud is coaxial with the main shaft and preventing the propulsion shroud from shifting.

[0010] As an optimization, the bottom of the propulsion cover is vertically equipped with a third telescopic device and a second slide rail via a mounting bracket. A long slider slides vertically on the second slide rail, and the long slider is equipped with a second bracket. A second pulley is located at the bottom of the second bracket. The output end of the third telescopic device is connected to the bottom of the second bracket, and the second pulley is slidably mounted on the first slide rail. By setting up the third telescopic device and the second bracket, the pulley can be raised and lowered, and the pulley can be supported. By setting up the second slide rail and the long slider, the stability of the pulley's raising and lowering can be ensured.

[0011] As an optimization, several sets of reinforcing ribs are provided on one side of the wall panel. By setting the reinforcing ribs, both the lightweight design requirements are met and the strength of the wall panel is enhanced, preventing deformation during the wrapping process.

[0012] Compared with the prior art, the present invention has the following beneficial effects: By setting up a first host, a second host, and a main shaft, two functions are established: first, to support and place the tire carcass cord; and second, to provide support and guidance for the movement of the wall panel. The wall panel and the first telescopic device enable the propulsion hood to move along the main shaft. The propulsion hood applies force evenly to the tire carcass cord in the circumference, ensuring complete and stable wrapping of the tire bead at the edge. The propulsion hood's deep thrust extends 300mm beyond the tire bead, achieving maximum wrapping effectiveness and reducing manual intervention. The second telescopic device and guiding components ensure stable movement of the propulsion hood, and the propulsion distance can be controlled as needed to guarantee the effectiveness and stability of the wrapping.

Detailed Implementation

[0021] To clearly illustrate the technical features of this solution, the present invention will be described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

[0022] Example 1 Figures 1 to 7 As one embodiment of this utility model, such as Figures 1 to 7 As shown, a giant tire reversing device includes a first main unit 1 and a second main unit 2. The first main unit 1 is fixedly installed on the ground, and the second main unit 2 is slidably installed on horizontal and vertical slide rails. It also includes two sets of wall panels 3 and two sets of propulsion covers 4. A main shaft 5 is provided between the first main unit 1 and the second main unit 2. The main shaft 5 includes a fixed section and a moving section. One end of the fixed section is connected to the first main unit 1, and one end of the moving section is connected to the second main unit 2. The other end of the fixed section is detachably connected to the other end of the moving section. A curtain tube 8 and a set of capsule drums 9 are provided on the fixed section, and another set of capsule drums 9 are provided on the moving section. The two sets of capsule drums 9 are located on both sides of the curtain tube 8. Several sets of first telescopic devices 6 are provided on both the first main unit 1 and the second main unit 2. The output end of the first telescopic device 6 is connected to one side of the wall panel 3. A sliding sleeve is provided in the center of the wall panel 3. The wall panel 3 is slidably installed on the main shaft 5 through the sliding sleeve. Several sets of second telescopic devices 7 are provided on one side of the wall panel 3. The output end of the second telescopic device 7 is connected to one side of the propulsion cover 4. The propulsion cover 4 is slidably installed on the wall panel 3 through a guide assembly.

[0023] By setting up the first host 1, the second host 2, and the main shaft 5, it can support the placement of the tire carcass cord 27 and provide support and guidance for the movement of the wall panel 3. By setting up the wall panel 3 and the first telescopic device 6, it can drive the propulsion cover 4 to move along the main shaft 5. By setting up the propulsion cover 4, it can apply force evenly to the tire carcass cord 27 in the circumference, so that the edge of the tire carcass cord 27 completely wraps around the tire bead 28. The wrapping is stable, and the propulsion distance of the propulsion cover 4 is deep, which can push past the tire bead 28 by 300mm to the flat width of the cord tube 8, achieving the maximum wrapping effect and reducing manual intervention. By setting up the second telescopic device 7 and the guide assembly, it can drive the propulsion cover 4 to move stably. The propulsion distance of the propulsion cover 4 can be controlled as needed to ensure the wrapping effect and stability.

[0024] like Figures 1 to 3 As shown, both the first host 1 and the second host 2 are also provided with several sets of guide seats 10, and several sets of first guide rods 11 are correspondingly provided on one side of the wall panel 3. The first guide rods 11 are slidably disposed in the guide seats 10 one by one. By setting the guide seats 10 and the first guide rods 11, firstly, they can cooperate with the main shaft 5 to provide guidance for the movement of the wall panel 3, thereby improving the stability of the movement of the wall panel 3; secondly, they can support the wall panel 3 and the propulsion cover 4, thereby reducing the pressure on the main shaft 5.

[0025] like Figure 6As shown, the propulsion cover 4 includes a base plate 12, a cylinder 13, and a cover body 14. The base plate 12 is annular, and its outer edge is connected to one end of the cover body 14 via the cylinder 13. The inner edge of the base plate 12 is connected to the other end of the cover body 14. The cover body 14 is cylindrical, with one end having a larger diameter than the other. The output end of the second telescopic device 7 is connected to the base plate 12. By setting the base plate 12 and the cylinder 13, the cover body 14 can be supported during the reverse wrapping process, ensuring its strength, preventing deformation, and guaranteeing the reverse wrapping effect. By setting the cover body 14 so that its inner side is inclined, the capsule can be pushed more effectively during the reverse wrapping process, ensuring the reverse wrapping effect.

[0026] like Figures 1 to 3 As shown, the guiding assembly includes several sets of guide sleeves 15 and several sets of second guide rods 16. The guide sleeves 15 are evenly fixed on one side of the wall panel 3, and the second guide rods 16 are correspondingly mounted on the base plate 12. The second guide rods 16 are slidably mounted one-to-one within the guide sleeves 15. By setting the guide sleeves 15 and the second guide rods 16, the axial movement of the propulsion cover 4 can be guided, avoiding deviation, and also providing auxiliary support for the propulsion cover 4.

[0027] like Figures 1 to 3 and Figure 5 As shown, it also includes a base 17, on which a first slide rail 18 is provided. A first bracket 19 is provided at the bottom of the push-up cover 4 on the first main unit 1, and a first pulley is provided at the bottom of the first bracket 19. The first pulley is slidably mounted on the first slide rail 18. By setting up the base 17, the first slide rail 18, the first bracket 19, and the first pulley, the movement of the push-up cover 4 can be supported, ensuring that the push-up cover 4 is coaxial with the main shaft and preventing the push-up cover 4 from shifting and colliding with the curtain tube 8.

[0028] like Figures 1 to 3 , Figure 5 and Figure 7 As shown, the bottom of the propulsion cover 4 on the second main unit 2 is vertically equipped with a third telescopic device 20 and a second slide rail 21 via a mounting bracket 26. A long slider 22 is vertically slidable on the second slide rail 21, and a second bracket 23 is provided on the long slider 22. A second pulley 25 is provided at the bottom of the second bracket 23. The output end of the third telescopic device 20 is connected to the bottom of the second bracket 23. The second pulley 25 is slidably mounted on the first slide rail 18. The first telescopic device 6, the second telescopic device 7, and the third telescopic device 20 are all hydraulic cylinders. By setting the third telescopic device 20 and the second bracket 23, the second pulley 25 can be raised and lowered, supporting the second pulley 25; by setting the second slide rail 21 and the long slider 22, the stability of the second pulley 25 during raising and lowering can be ensured.

[0029] like Figures 1 to 3As shown, several sets of reinforcing ribs 24 are provided on one side of the wall panel 3. By setting the reinforcing ribs 24, both the lightweight design can be met and the strength of the wall panel 3 can be enhanced, preventing deformation during the wrapping process.

[0030] In use, the tire carcass transfer ring (not shown in the figure) enters the work station via the transverse and longitudinal slide rails (not shown in the figure), transferring the tire carcass ply 27 to the ply tube 8. Then, the tire carcass transfer ring is removed, and the tire bead 28 is fitted onto the edge of the ply tube 8. The second main unit 2 enters the work station via the transverse and longitudinal slide rails, as follows: Figure 7 As shown, the output end of the third telescopic device 20 extends, causing the long slider 22 to move downward along the second slide rail 21, driving the second bracket 23 to move downward, so that the second pulley 25 abuts against the first slide rail 18, supporting the corresponding propulsion cover 4; the other end of the fixed section connects with the other end of the moving section, and the two ends of the tire carcass ply 27 are respectively on the two sets of capsule drums 9; during the reverse wrapping, the capsule drum 9 is inflated, and the two ends of the tire carcass ply 27 slowly widen. After the capsule drum 9 is inflated to a certain extent, the output end of the first telescopic device 6 extends, pushing the wall plate 3 and the propulsion cover 4 together to move towards the tire carcass ply 27. The first pulley and the long slider 22 slide on the first slide rail 18, supporting the corresponding propulsion cover 4; as Figure 5 and Figure 6 As shown, after the first telescopic device 6 is pushed forward, the output end of the second telescopic device 7 extends out, pushing the pusher cover 4 to move towards the tire carcass ply 27. The cover 14 abuts against and pushes the expanded bladder of the bladder drum 9, causing the bladder to wrap around the tire bead 28. As the pusher cover 4 continues to push forward, it can go beyond the position of the tire bead 28 and push it to the flat width position of the ply tube 8, thereby achieving complete wrapping without manual adjustment.
