Description
Technical Field
[0001] This invention relates to the field of ultraviolet curing pipe technology, specifically to a production process for glass fiber flexible hoses based on ultraviolet curing pipe repair. Background Technology
[0002] UV-cured lining repair is a trenchless repair technology that has gradually become one of the mainstream technologies for trenchless pipeline repair due to its advantages such as high material strength and safe and reliable repair construction. As an indispensable repair material for UV-cured lining repair technology, the production and manufacturing of related UV-cured hoses has also become increasingly mature.
[0003] The UV-curable flexible tube, from the inside out, consists of: 1. A translucent inner membrane: maintaining internal pressure to ensure the inner tube's round shape, allowing UV light to pass through and cure the resin; 2. A resin-fiberglass reinforcement layer: the main structure of the inner tube, providing high modulus and strength after curing; 3. An outer protective membrane: providing waterproofing and resin protection. Currently, domestic UV-curable flexible tubes are almost entirely manufactured using a manual splicing process, which is inefficient, labor-intensive, and poses health risks to workers due to fiberglass debris. More importantly, the manual splicing method cannot guarantee the precision of the tube manufacturing process, resulting in air bubbles or uneven wall thickness after curing, significantly affecting the quality of the inner tube after pipe repair. Given these shortcomings, it is necessary to design a UV-curable pipe repair manufacturing process for fiberglass flexible tubes. Summary of the Invention
[0004] The purpose of this invention is to provide a manufacturing process for glass fiber hoses based on ultraviolet light curing for pipe repair, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a manufacturing process for fiberglass hoses based on ultraviolet light curing for pipe repair, the manufacturing process steps of which are as follows: Step 1. Weaving: Glass fiber filaments are woven together using a weaving mechanism to obtain a tubular glass fiber tube; Step 2. Blow molding: The raw material granules are extruded and blow molded using a blow molding mechanism to obtain a cylindrical inner film; Step 3. Flattening; The cylindrical glass fiber tube and inner membrane are flattened using an extrusion mechanism; Step 4. Impregnation: The air in the pores of the glass fiber tube with the inner membrane is extracted by the impregnation mechanism and immersed in the impregnation liquid. Then, the impregnation liquid is impregnated into the glass fiber tube by vacuum pressure to make it fully absorb the impregnation liquid. Step 5: Lamination: The outer membrane is laminated onto the glass fiber tube using a lamination mechanism.
[0006] Preferably, the weaving process in step one specifically includes: The motor drives the drive gear to rotate, and the driven gear, shaft and dial also rotate, thereby driving the spindle to move in the weaving track, so that the glass fiber filaments are continuously wound into a cylindrical glass fiber tube on the outer wall of the guide tube.
[0007] Preferably, the blow molding process in step two specifically includes: Raw material granules are fed into the extruder through the feed funnel. The extruder extrudes the raw material granules into the annular groove of the blow molding machine and blows them out through the annular groove. The air pump blows the raw material granules through the air blowing hole to form a cylindrical inner film. The inner film moves along the inner wall of the guide tube.
[0008] Preferably, the flattening process in step three specifically includes: The motor drives the drive sprocket to rotate, and the chain also rotates, thereby moving the traction block. Because the traction block, glass fiber tube, and guide tube are in close contact, the traction block can pull the glass fiber tube along the guide tube. When both the glass fiber tube and the inner membrane extend out of the guide tube, the inner membrane continues to bulge under the action of the air pump. The outer wall of the inner membrane contacts the inner wall of the glass fiber tube, so that the outer wall of the inner membrane wraps around the inner wall of the glass fiber tube. The traction block pulls the glass fiber tube with the inner membrane wrapped inside to the extrusion assembly. After passing through the guide roller, it enters between the two pressure plates. The electric cylinder drives the pressure plates to move, and the two rows of extrusion rollers also move. The extrusion rollers cooperate with the extrusion block to flatten the cylindrical glass fiber tube and the inner membrane into a flat shape.
[0009] Preferably, the impregnation process in step four specifically includes: The flat glass fiber tube is pulled into the impregnation tank by the drive roller. The vacuum pump works to evacuate the inside of the impregnation tank, which can remove the air from the pores of the glass fiber tube. Then, the cylinder pushes the lifting plate one to move downward, and the tension roller and the immersion roller also move downward. The immersion roller drives the glass fiber tube downward, so that the glass fiber tube is immersed in the impregnation liquid. The compressor works to pressurize the inside of the impregnation tank. Under the action of vacuum pressure, it can be ensured that the impregnation liquid completely fills the pores of the glass fiber tube, so that it can fully absorb the impregnation liquid and leave no air bubbles. After impregnation, the excess impregnation liquid on the glass fiber tube is squeezed out by the squeeze roller two.
[0010] Preferably, the composite process in step five specifically includes: Two traction rollers pull the outer film from two unwinding rolls, causing it to pass through guide roller two, traction rollers, and guide plate onto the material support frame. A slide cylinder drives a pneumatic gripper to move to the outer film, clamping it. A motor drives a drive pulley, which in turn moves a belt, causing the connecting block to move as well. This moves a moving plate along a slide rail, moving the pneumatic gripper and the outer film below the longitudinal hot-pressing assembly. The pneumatic gripper releases the outer film, and the slide cylinder moves it away from the film. The hot-pressing cylinder moves the lifting plate two downwards, causing the hot-pressing plate to move downwards as well. An electric heating wire is energized to heat the hot-pressing plate, allowing it to press against the two outer films. During heat sealing, the drive roller pulls the glass fiber tube between the two outer films, allowing the outer films to wrap around the glass fiber tube. Motor 3 drives the pneumatic gripper to move to the glass fiber tube, and the slide cylinder drives the pneumatic gripper to move onto the glass fiber tube. The pneumatic gripper clamps the glass fiber tube and the outer film. Motor 3 drives the pneumatic gripper to move, and the glass fiber tube and the outer film move accordingly. When the glass fiber tube moves to the required length, the cutting cylinder drives the cutting blade mounting frame to move downward, and the cutting blade also moves downward to cut the glass fiber tube. When the outer film is unwound to the required length, the cutting component 2 cuts it. The outer film is then heat-pressed by the transverse hot pressing component and the longitudinal hot pressing component, thereby bonding the outer film to the glass fiber tube.
[0011] Compared with the prior art, the technical solution provided by the present invention has at least the following technical effects or advantages: This invention features an impregnation mechanism. A vacuum pump creates a vacuum inside the impregnation tank, removing air from the pores of the glass fiber tube. A cylinder then pushes a lifting plate downwards, causing the tension roller and immersion roller to move downwards as well. The immersion roller moves the glass fiber tube downwards, immersing it in the impregnation solution. A compressor pressurizes the impregnation tank, ensuring the impregnation solution completely fills the pores of the glass fiber tube under vacuum pressure, allowing for full absorption and eliminating air bubbles. After impregnation, a second extrusion roller squeezes out excess impregnation solution from the glass fiber tube, allowing it to fall back into the impregnation tank, thus reducing waste. The invention also includes a lamination mechanism for unwinding and cutting the outer film and laminating it onto the glass fiber tube. This highly automated process reduces the need for frequent manual operation, improving production efficiency. Attached Figure Description

[0026] This invention provides another technical solution: a manufacturing process for fiberglass hoses based on ultraviolet light curing for pipe repair, the manufacturing process steps of which are as follows: Step 1. Weaving: The glass fiber filaments are woven together using weaving mechanism 1 to obtain a tubular glass fiber tube; Step 2. Blow molding: The raw material granules are extruded and blow molded through the blow molding mechanism 2 to obtain a cylindrical inner film; Step 3. Flattening; The cylindrical glass fiber tube and inner membrane are flattened by the extrusion mechanism 3; Step 4. Impregnation: The air in the pores of the glass fiber tube with the inner membrane is extracted by the impregnation mechanism 4 and immersed in the impregnation liquid. Then, the impregnation liquid is impregnated into the glass fiber tube by vacuum pressure so that it can fully absorb the impregnation liquid. Step 5: Lamination: The outer membrane is laminated onto the glass fiber tube using lamination mechanism 5; The weaving process in step one specifically includes: The motor 105 drives the drive gear 104 to rotate, and the driven gear 103, the rotating shaft 102 and the dial 107 also rotate, thereby driving the spindle 109 to move in the braiding track 106, so that the glass fiber filaments are continuously wound into a cylindrical glass fiber tube on the outer wall of the guide tube 207. The blow molding process in step two specifically includes: Raw material granules are fed into extruder 204 through feed funnel 205. Extruder 204 extrudes the raw material granules into the annular groove 202 of blow molding machine 201 and blows them out through the annular groove 202. Air pump blows the raw material granules through air blowing hole 206 to form a cylindrical inner film. The inner film moves along the inner wall of guide tube 207. The flattening process in step three specifically includes: The motor 302 drives the drive sprocket 304 to rotate, and the chain 303 also rotates, thereby driving the traction block 301 to move. Since the traction block 301, the glass fiber tube and the guide tube 207 are in close contact, the traction block 301 can pull the glass fiber tube to move along the guide tube 207. When both the glass fiber tube and the inner membrane extend out of the guide tube 207, the inner membrane continues to bulge under the action of the air pump. The outer wall of the inner membrane contacts the inner wall of the glass fiber tube, so that the outer wall of the inner membrane wraps around the inner wall of the glass fiber tube. The traction block 301 pulls the glass fiber tube with the inner membrane wrapped inside to the extrusion assembly. After passing through the guide roller 308, it enters between the two pressure plates 310. The electric cylinder 314 drives the pressure plate 310 to move, and the two rows of extrusion rollers 311 also move. The extrusion rollers 311 cooperate with the extrusion block 312 to flatten the cylindrical glass fiber tube and the inner membrane into a flat shape. The impregnation process in step four specifically includes: The flat glass fiber tube is pulled into the impregnation tank 401 by the drive roller 412. The vacuum pump works to evacuate the inside of the impregnation tank 401, which can extract the air from the pores of the glass fiber tube. Then, the cylinder 406 pushes the lifting plate 405 to move downward. The tension roller 407 and the immersion roller 408 also move downward. The immersion roller 408 drives the glass fiber tube to move downward, so that the glass fiber tube is immersed in the impregnation liquid. The compressor works to pressurize the inside of the impregnation tank 401. Under the action of vacuum pressure, it can be ensured that the impregnation liquid completely fills the pores of the glass fiber tube, so that it can fully absorb the impregnation liquid and leave no air bubbles. After impregnation, the excess impregnation liquid on the glass fiber tube is squeezed out by the squeeze roller 409. The composite process in step five specifically includes: Two traction rollers 506 pull the outer film on two unwinding rolls 508 to unwind it, so that the outer film on the unwinding roll 508 is unwound onto the material support frame 501 via guide roller 509, traction roller 506, and guide plate 510. The slide cylinder 512 drives the pneumatic gripper 511 to move to the outer film, where it grips it. Motor 521 drives the drive pulley 519 to rotate, which in turn drives the belt 518 to move. The connecting block 517 also moves, thus moving the moving plate 513 along the slide rail 515. This moves the pneumatic gripper 511 and the outer film below the longitudinal hot pressing assembly. The pneumatic gripper 511 releases the outer film, and the slide cylinder 512 moves the pneumatic gripper 511 away from the outer film. The hot pressing cylinder 522 moves the lifting plate 524 downward, and the hot pressing plate 527 also moves downward. The electric heating wire is energized to heat the pressing assembly. The plate 527 is heated, causing the hot press plate 527 to heat-seal the two outer films. At the same time, the drive roller 412 pulls the glass fiber tube between the two outer films, so that the outer films can wrap the glass fiber tube. The motor 3 521 drives the pneumatic gripper 511 to move to the glass fiber tube. The slide cylinder 512 drives the pneumatic gripper 511 to move onto the glass fiber tube. The pneumatic gripper 511 clamps the glass fiber tube and the outer film. The motor 3 521 drives the pneumatic gripper 511 to move, and the glass fiber tube and the outer film also move with it. When the glass fiber tube moves to the required length, the cutting cylinder 503 drives the cutting knife mounting frame 504 to move downward, and the cutting knife 505 also moves downward to cut the glass fiber tube. When the outer film is unwound to the required length, the cutting component 2 cuts it. The outer film is hot-pressed by the transverse hot press component and the longitudinal hot press component, so that the outer film can be laminated onto the glass fiber tube.

Under the action of vacuum pressure, it can be ensured that the impregnation liquid is completely filled into the pores of the glass fiber tube, so that it can fully absorb the impregnation liquid and leave no air bubbles. After impregnation, the excess impregnation liquid on the glass fiber tube is squeezed out by the squeeze roller (409).
6. The manufacturing process of a glass fiber flexible hose based on ultraviolet light curing for pipe repair according to claim 1, characterized in that: The composite process in step five specifically includes: Two traction rollers (506) pull the outer film on two unwinding rolls (508) to unwind it, so that the outer film on the unwinding roll (508) is unwound onto the material support frame (501) via guide roller two (509), traction roller (506) and guide plate (510). The slide cylinder (512) drives the pneumatic gripper (511) to move to the outer film, and the pneumatic gripper (511) clamps the outer film. Motor three (521) drives the drive pulley (519) to rotate, and the drive pulley (519) drives the outer film to rotate. The moving belt (518) moves, and the connecting block (517) moves accordingly, thereby driving the moving plate (513) to move. The moving plate (513) moves along the slide rail (515), which in turn drives the pneumatic gripper (511) and the outer membrane to move below the longitudinal hot pressing assembly. The pneumatic gripper (511) releases the outer membrane, and the slide cylinder (512) drives the pneumatic gripper (511) away from the outer membrane. The hot pressing cylinder (522) drives the lifting plate (524) to move downward, and the hot pressing plate (527) also moves downward. The electric heating wire is energized to heat the hot press plate (527), causing the hot press plate (527) to heat-seal the two outer films. At the same time, the drive roller (412) pulls the glass fiber tube between the two outer films, so that the outer films can wrap the glass fiber tube. The motor three (521) drives the pneumatic gripper (511) to move to the glass fiber tube. The slide cylinder (512) drives the pneumatic gripper (511) to move onto the glass fiber tube, and the pneumatic gripper (511) clamps the glass fiber tube and the outer film. Motor 3 (521) drives the pneumatic gripper (511) to move, and the glass fiber tube and outer film also move. When the glass fiber tube moves to the required length, the cutting cylinder (503) drives the cutting knife mounting bracket (504) to move downward, and the cutting knife (505) also moves downward to cut the glass fiber tube. When the outer film is unwound to the required length, the cutting component 2 cuts it. The outer film is hot-pressed by the transverse hot-pressing component and the longitudinal hot-pressing component, so that the outer film can be composited onto the glass fiber tube.
