Description

Technical Field

[0001] This utility model relates to the field of light-curing hose manufacturing technology, specifically to a fabric rack for light-curing hose manufacturing. Background Technology

[0002] Currently, the fabric laying process for trenchless UV-curing repair hoses is mostly achieved manually by rolling the fabric roll to lay a single layer of fabric before laying the next layer on top, repeating this layer-by-layer method. This is particularly challenging when threading the traction wire into the inner membrane layer, which is achieved manually by squeezing air to roll the traction wire – a method fraught with difficulties. Manually fabricating multiple layers is labor-intensive, inefficient, and prone to significant fabric misalignment, affecting both production efficiency and product quality. Furthermore, it requires multiple people to complete the multi-layer fabric fabrication, resulting in low efficiency and high cost. Therefore, the development of a fabric laying frame for UV-curing hoses has become a new challenge for technicians in my country's trenchless pipeline repair hose equipment manufacturing industry. Utility Model Content

[0003] The main purpose of this utility model is to provide a fabric rack made of light-cured flexible tube that allows multiple layers of fabric to be stacked together after being wrapped around.

[0004] To achieve the above objectives, the technical solution provided by this utility model is as follows: A fabric rack for manufacturing photocurable flexible tubes is fixed to a base and includes a frame. Two first supports are fixed to the lower end of one side of the frame, and these first supports are rotatably connected to a first roller. Two second supports are fixed to the upper end of one side of the frame, and these second supports are rotatably connected to a second roller. The second roller corresponds vertically to the first roller. Multiple winding components are fixed on the frame and are staggered. Each winding component includes two fourth supports and a fourth roller. The two fourth supports support both ends of the fourth roller, allowing both ends of the fourth roller to rotate within the two fourth supports. Two third supports are fixed to one side of the upper end of the frame, supporting both ends of a third roller, allowing both ends of the third roller to rotate within the two third supports. The third roller is close to and below the second roller. The first, second, third, and fourth rollers are parallel. A fifth roller, corresponding to the fourth roller, is rotatably mounted inside the lower end of the frame. The fifth roller is parallel to the first roller, and its lower end is flush with the lower end of the first roller.

[0005] Specifically, multiple fabric rolls are respectively mounted on multiple fourth rollers. The free end of the fabric passes over the lower end of a fifth roller and is located below the first roller. The inner film roll is mounted on a third roller. The free end of the inner film passes over the upper end of the second roller and the lower end of the first roller in sequence. The inner film is located at the upper end of the multi-layer fabric below the first roller.

[0006] Specifically, both ends of the fifth roller are rotatably connected to a fifth support, which is fixed inside the lower end of the frame.

[0007] Specifically, the inner film portion between the first rotating roller and the inner film roll is filled with air. The inner film portion between the first rotating roller and the inner film roll expands and forms a storage cavity inside. A traction coil is placed inside the storage cavity, and the free end of the traction coil passes through the free end of the inner film.

[0008] Specifically, multiple side supports are fixed at both ends of the frame.

[0009] Specifically, each of the first, second, third, fourth, and fifth rollers is fitted with two collars, and the collars are threaded with positioning screws.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The storage cavity design formed by the expansion of the inner film can directly accommodate the traction coil and achieve automatic unwinding during the pulling process. This avoids the introduction of additional traction equipment, reduces manual intervention, and significantly improves production efficiency. The inner film remains in an expanded state between the inner roll and the second roller, ensuring stable release of the traction coil within the storage cavity and preventing the coil from knotting or shifting. This is particularly suitable for continuous production scenarios of UV-curable tubes.

[0011] 2. By setting collars, users can flexibly adjust the limit positions on the first, second, third, fourth, and fifth rollers, achieving precise control over the fabric roll, inner film roll, inner film, and multi-layer fabrics, preventing the inner film and fabric from shifting or misaligning during high-speed movement. It adapts to different roll sizes, improving the equipment's versatility and error tolerance, and reducing scrap rates.

[0012] 3. The staggered arrangement of multiple winding components supports the simultaneous installation and operation of multiple fabric rolls. Each fabric roll corresponds to a fifth roller, forming an independent but coordinated unwinding path. The free end of the fabric passes around the fifth roller and is stacked below the first roller. This structure allows the factory to process multiple fabric rolls simultaneously, enabling parallel production, shortening the overall processing time, and is especially suitable for mass production environments.

[0013] 4. The first, second, third, fourth and fifth rollers are arranged in parallel, and the lower end of the fifth roller is flush with the lower end of the first roller. This ensures that the transmission path of the fabric and inner film is smooth and without twisting, optimizes the bypass path of the inner film, reduces material friction loss and extends the service life of the equipment.

[0014] 5. The modular design of the collar and positioning screws facilitates quick replacement of the roll material or adjustment of the limit. Daily maintenance can be completed without special tools. The inner membrane expansion mechanism automatically maintains the state of the storage cavity, reducing the need for manual monitoring. This design reduces the complexity of operation, allowing novice users to get started quickly, while reducing downtime and improving equipment utilization. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figures 1-3 As shown, a fabric rack for manufacturing photocurable flexible tubes is fixed to a base and includes a frame 10. Multiple side supports 11 are fixed to both ends of the frame 10. Two first supports 12 are fixed to the lower end of one side of the frame 10, and these two first supports 12 are rotatably connected to a first rotating roller 21. Two second supports 13 are fixed to the upper end of one side of the frame 10, and these two second supports 13 are rotatably connected to a second rotating roller 22. The second rotating roller 22 corresponds vertically to the first rotating roller 21. Multiple winding components are fixed on the frame 10, and these winding components are staggered.

[0021] The winding assembly includes two fourth supports 17 and a fourth roller 23. The two fourth supports 17 support both ends of the fourth roller 23, and both ends of the fourth roller 23 can rotate within the two fourth supports 17 respectively. Two third supports 14 are fixed to one side of the upper end of the frame 10. The two third supports 14 support both ends of the third roller 20, and both ends of the third roller 20 can rotate within the two third supports 14 respectively. The third roller 20 is close to and below the second roller 22.

[0022] The first roller 21, the second roller 22, the third roller 20, and the fourth roller 23 are parallel.

[0023] A fifth roller 24, corresponding to the fourth roller 23, is rotatably mounted inside the lower end of the frame 10. Both ends of the fifth roller 24 are rotatably connected to a fifth support 18, which is fixed inside the lower end of the frame 10. The fifth roller 24 is parallel to the first roller 21, and the lower end of the fifth roller 24 is flush with the lower end of the first roller 21.

[0024] Multiple fabric rolls 16 are respectively mounted on multiple fourth rollers 23, with the free ends of the fabrics passing over the lower end of a fifth roller 24 and positioned below the first roller 21. An inner film roll 15 is mounted on a third roller 20, with the free ends of the inner film successively passing over the upper end of a second roller 22 and the lower end of the first roller 21. The inner film is located below the first roller 21 at the upper end of the multi-layered fabric.

[0025] Air is filled in the inner membrane portion between the first roller 21 and the inner membrane roll 15. The inner membrane portion between the first roller 21 and the inner membrane roll 15 expands and forms a storage cavity inside. A traction coil 19 is placed in the storage cavity, and the free end of the traction coil 19 passes through the free end of the inner membrane.

[0026] Two collars 25 are fitted on the first roller 21, the second roller 22, the third roller 20, the fourth roller 23 and the fifth roller 24, and positioning screws 26 are threaded onto the collars 25.

[0027] In use, multiple fabric rolls 16 are respectively mounted on multiple fourth rollers 23, and the inner film roll 15 is mounted on the third roller 20. At this time, multiple fabric rolls 16 correspond one-to-one with multiple fifth rollers 24, so that the free end of the fabric passes around a fifth roller 24 and then passes under the first roller 21. Multiple layers of fabric are stacked under the first roller 21. Then, the free end of the inner film passes around the upper end of the second roller 22 and fills the inner film portion between the second roller 22 and the inner film roll 15 with air through the free end of the inner film. The inner film portion between the first roller 21 and the inner film roll 15 expands and forms a storage cavity inside. The traction coil 19 is placed into the storage cavity, and the free end of the traction coil 19 passes out from the free end of the inner film. Then, the free end of the inner film and the free end of the traction coil 19 pass around the lower end of the first roller 21 and are located at the upper end of the multiple layers of fabric. When the free ends of the fabric, the free ends of the inner film and the free ends of the traction coil 19 are pulled, the inner film portion between the inner film roll 15 and the second roller 22 is always in an expanded state. During the process of the inner film winding out, the traction coil 19 is always unwound in the storage cavity.

[0028] By setting the collars 25, the positions of the two collars 25 on the first rotating roller 21 can be adjusted. The two collars 25 on the first rotating roller 21 can limit the multi-layer fabric below the first rotating roller 21. Adjusting the positions of the two collars 25 on the second rotating roller 22 can limit the inner film. Adjusting the positions of the two collars 25 on the fifth rotating roller 24 can limit the fabric. The two collars 25 on the fourth rotating roller 23 can limit the fabric roll 16. The two collars 25 on the third rotating roller 20 can limit the inner film roll 15.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
