Description

Technical Field

[0001] This utility model relates to the field of tire manufacturing technology, specifically a device for correcting the alignment of rolled-up padding fabric. Background Technology

[0002] During tire production, after the inner liner film is calendered, it needs to be wound up by a winding machine and wrapped with a pad to prevent the film from sticking together. During the winding process, the pad must be evenly and flatly covered on the surface of the film, and its position must be precisely aligned with the film.

[0003] However, in actual production, factors such as winding tension fluctuations, guide roller installation deviations, equipment vibrations, or material slippage can lead to uneven coverage of the padding cloth, or even partial exposure of the film. This not only affects subsequent processes (such as cutting and bonding), but may also cause film contamination, adhesion, or edge damage, reducing product yield and production efficiency.

[0004] Currently, the method used to solve the above problems is that the inner lining layer covered with padding cloth is wound onto the I-beam after passing through multiple guide rollers. During this process, the alignment of the padding cloth depends entirely on the mechanical limit of the fixed guide rollers and the experience of the operator. The operator needs to monitor the winding status at all times. If the padding cloth is found to be off-center, the machine must be stopped immediately, and the correction can be made by manually adjusting the position of the guide rollers or even by pulling the padding cloth by hand. This manual correction method has problems such as low production efficiency, high labor intensity, and extremely high requirements for the employee's sense of responsibility and experience. More importantly, manual intervention in adjustment while the equipment is running poses a risk of limbs being caught in the equipment, resulting in prominent safety hazards.

[0005] To solve this problem, there is an urgent need to develop a correction device to achieve the comprehensive goals of stabilizing product quality, improving production efficiency, reducing costs, and eliminating safety hazards. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by providing a deviation correction device for winding mats. This device actively corrects the deviation of the conveyed mats through mechanization, thereby improving production quality and efficiency and avoiding the safety hazards associated with manual operation.

[0007] The technical solution of this utility model is: a correction device for rolling up padding cloth, including a correction mechanism and a detection mechanism; The correction mechanism includes a frame, on which a crossbeam is rotatably connected, and a first telescopic arm for driving the crossbeam to rotate is provided. A set of vertically arranged horizontal shafts are rotatably connected to the front side of the crossbeam. The detection mechanism includes a column, and an edge detector is mounted on the top of the column via an L-shaped right-angle bracket. The edge detector is used to detect the edge of the padding fabric conveyed by the upper horizontal axis. The edge detector is electrically connected to the first telescopic arm and is used to control the operation of the first telescopic arm.

[0008] Preferably, a set of lugs is provided on the front side of the free end of the crossbeam, and a swing seat is rotatably connected to the set of lugs. The free end of the crossbeam is also provided with a second telescopic arm that drives the swing seat to swing. The end of the cross shaft near the swing seat is rotatably connected to the swing seat.

[0009] Preferably, a set of the horizontal shafts consists of two vertically arranged shafts, and a reinforcing plate is rotatably connected to the ends of the two horizontal shafts.

[0010] Preferably, the free end of the right-angle bracket is provided with a third telescopic arm, the movable end of the third telescopic arm is fixedly connected to the edge detector, and the movement direction of the third telescopic arm is arranged perpendicular to the pad conveying direction.

[0011] Preferably, the first telescopic arm, the second telescopic arm, and the first telescopic arm are all electro-hydraulic cylinders or electric push rods.

[0012] Compared with the prior art, this utility model has the following advantages: This utility model, through the combination of a detection mechanism and a correction mechanism, can correct the problem of the pad fabric running off-center in real time and proactively, fundamentally avoiding the exposure, adhesion, tearing and surface damage of the inner lining film caused by the pad fabric running off-center, significantly reducing the scrap rate and saving production costs. Furthermore, it replaces the work mode that relies on manual monitoring and adjustment, eliminates frequent downtime caused by deviations in handling, ensures the continuity and stability of production, effectively improves the overall efficiency and capacity of the equipment, and reduces the excessive reliance on the experience and sense of responsibility of the operators at this workstation. At the same time, it can solve safety hazards during operation, eliminate direct contact and intervention between operators and operating equipment during production, fundamentally eliminate the safety risk of limbs being caught in the equipment, and create a safer working environment. In addition, the equipment has a simple structure and occupies little space, making it particularly suitable for the technical transformation and upgrading of existing old winding machines. It has extremely high promotional value and economic benefits. Attached Figure Description

[0014] The present invention will be further described below with reference to the accompanying drawings and embodiments. Example 1

[0015] like Figures 1 to 3 A web-correcting device for rolling up a mat includes a web-correcting mechanism 1 and a detection mechanism 2.

[0016] The correction mechanism 1 includes a frame 10, on which a crossbeam 7 is rotatably connected. Two vertically arranged horizontal shafts 8 are rotatably connected to the front side of the crossbeam 7. The pad 15 is conveyed through the horizontal shafts 8. To further increase the structural stability, a reinforcing plate 9 can be rotatably connected to the end of the two horizontal shafts 8.

[0017] A first telescopic arm 6 for driving the crossbeam 7 to rotate is also provided between the crossbeam 7 and the frame 10. The first telescopic arm 6 is arranged at an angle, and the lower end of the first telescopic arm 6 is hinged to the frame 10, and the upper end of the first telescopic arm 6 is hinged to the middle of the crossbeam 7.

[0018] The detection mechanism 2 includes a column 11. An edge detector 14 is mounted on the top of the column 11 via an L-shaped right-angle bracket 12. The edge detector 14 is used to detect the edge of the pad 15 being conveyed by the upper horizontal axis 8. The edge detector 14 is electrically connected to the first telescopic arm 6 and is used to control the operation of the first telescopic arm 6.

[0019] Working principle: When in use, push the trolley 16 into the work station from the side away from the detection mechanism 2, so that the vertical part of the pad 15 unfolds and wraps around the outside of the two horizontal shafts 8, and the edge detector 14 is used to detect the position of one edge of the pad 15. During the rolling operation of the pad 15, the axial movement of the edge of the pad 15 is monitored in real time by the edge detector 14. The edge detector 14 has a preset allowable range for the axial movement of the edge of the pad 15. Once the pad 15 deviates beyond the preset allowable range, the edge detector 14 controls the first telescopic arm 6 to swing, raising one end of the horizontal axis 8, thereby straightening the pad 15 in the direction of the deviated side. After the edge detector 14 detects that the edge of the pad 15 has returned to the correct position, it controls the first telescopic arm 6 to reset so that the horizontal axis 8 returns to the horizontal state. Example 2

[0020] This embodiment is a further optimization based on the above embodiment, specifically: like Figures 1 to 3 A pair of lugs 5 are provided on the front side of the free end of the crossbeam 7. A swing seat 4 is rotatably connected through the pair of lugs 5. A second telescopic arm 3 is provided on the free end of the crossbeam 7. One end of the second telescopic arm 3 is hinged to the crossbeam 7 and the other end is hinged to the swing seat 4. Thus, the swing seat can be driven to swing through the second telescopic arm 3. The end of the horizontal shaft 8 near the swing seat 4 is rotatably connected to the swing seat 4.

[0021] This design utilizes the second telescopic arm 3 to drive the swing seat 4 to swing the horizontal shaft 8, allowing the outer edge of the horizontal shaft 8 to unfold a certain distance. After unfolding, when the trolley 16 is pushed into the work station, it is convenient to wrap the unfolded pad 15 on the trolley 16 around the outside of the two horizontal shafts 8. Then, the second telescopic arm 3 drives the swing seat 4 to return to its original position, allowing the two horizontal shafts 8 to return to their original position and the pad 15 to be stretched and conveyed. Example 3

[0022] This embodiment is a further optimization based on the above embodiment, specifically: like Figure 1 and Figure 3 The free end of the right-angle bracket 12 is provided with a third telescopic arm 13. The moving end of the third telescopic arm 13 is fixedly connected to the edge detector 14. The movement direction of the third telescopic arm 13 is arranged perpendicular to the conveying direction of the pad 15.

[0023] When the trolley 16 is pushed into the work station, in order to prevent the pad 15 from touching the edge detector 14, the edge detector 14 can be moved back to make way by the third telescopic arm 13. After the trolley 16 is pushed into place, the edge detector 14 is pushed to the detection position by the third telescopic arm 13. The detection position can also be finely adjusted by the extension distance of the third telescopic arm 13.

[0024] Additionally, it is worth noting that the first telescopic arm 6, the second telescopic arm 3, and the third telescopic arm 13 described above are all electro-hydraulic cylinders or electric push rods. The electro-control method can be achieved by directly controlling their operation using the edge detector 14. The edge detector 14 uses a German Lemer E+L model FR5301 correction sensor in conjunction with a computer for debugging and testing.

[0025] This utility model is not limited to the above-described embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this utility model, and the changed content still falls within the protection scope of this utility model.
