A composite fiber winding machine for high-pressure vessels made of composite materials

Abstract

This utility model discloses a composite fiber winding machine for high-pressure vessels made of composite materials, including a platform plate. Support connecting plates are fixedly connected to the front and rear sides of the top center of the platform plate, and a rotating motor is fixedly connected to the front end of each support connecting plate. In this utility model, starting the rotating motor drives a reciprocating screw to rotate. The rotation of the reciprocating screw causes a movable block on the outer wall to move back and forth, thereby moving the composite fiber belt inside the top guide slip ring sleeve. Simultaneously, the rotating motor drives the reciprocating screw to rotate, which in turn drives the rear drive gear to rotate. The rotation of the drive gear drives the gear timing belt to rotate, which in turn drives the driven gear on the left side to rotate. The rotation of the driven gear drives the locking block to rotate, thereby driving the take-up roller to rotate, ensuring the stability of the take-up roller's winding.

Description

Technical Field

[0001] This utility model relates to the field of composite fiber winding machine technology, and in particular to a composite fiber winding machine for high-pressure vessels of composite materials. Background Technology

[0002] Composite high-pressure vessels are pressure vessels made using composite materials and designed to safely store gases or liquids under high-pressure conditions. These vessels are typically composed of high-strength fibers (such as carbon fiber, glass fiber, etc.) and a resin matrix (such as epoxy resin), manufactured through specific processes. Composite fiber winding machines are key equipment in the manufacture of composite high-pressure vessels. They form the outer shell of the vessel by impregnating continuous composite fibers (such as carbon fiber or glass fiber) in resin and winding them onto a mandrel according to a preset pattern.

[0003] Currently, most composite fiber winding machines use separate devices to drive the composite fiber belt forward and backward and to drive the winding roller. Furthermore, since the composite fiber belt is impregnated with resin on its outer wall, it cannot be guaranteed that the resin will not drip during the transport of the composite fiber belt. The dripping resin (such as epoxy resin, unsaturated polyester, etc.) not only wastes materials but may also contaminate the equipment, affect the working environment, and even make it difficult to clean after curing.

[0004] Therefore, how to provide a composite fiber winding machine for high-pressure vessels made of composite materials is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] One objective of this invention is to provide a composite fiber winding machine for high-pressure containers of composite materials. By incorporating a transmission component, the machine can drive the composite fiber belt to move back and forth while simultaneously rotating the winding roller, facilitating the winding of the composite fiber belt. Furthermore, while winding the composite fiber belt, the machine can also drive the scraping strip at the bottom to scrape and collect the dripping resin adhesive, thereby solving the problems mentioned in the background art.

[0006] A composite fiber winding machine for high-pressure vessels according to an embodiment of the present invention includes a platform plate. Support connecting plates are fixedly connected to both the front and rear sides of the top center of the platform plate. A rotary motor is fixedly connected to the front end of the support connecting plate, and a reciprocating screw is fixedly connected to the output end of the rotary motor. Two guide rods are fixedly connected between the support connecting plates on the side near the movable block of the platform plate. The outer walls of the guide rods are slidably connected to the movable block. A movable block is threadedly connected to the outer wall of the reciprocating screw. A scraping strip is fixedly connected to the bottom of the movable block. Two guide slip rings are fixedly connected to the top of the movable block. A drive gear is fixedly connected to the rear end of the reciprocating screw. A gear timing belt meshes with the outer wall of the drive gear. A driven gear meshes with the inner left wall of the gear timing belt. The outer wall of the driven gear is rotatably connected to the support plate.

[0007] As a preferred embodiment of this utility model: the driven gear has a locking groove inside, a locking block is locked inside the locking groove, a take-up roller is fixedly connected to the front end of the locking block, and the front end of the take-up roller is rotatably connected to the movable support plate.

[0008] As a further preferred embodiment of this utility model: two telescopic spring rods are fixedly connected to the bottom front end of the movable support plate, and the end of the telescopic spring rod away from the movable support plate is fixedly connected to the platform plate.

[0009] As a further preferred embodiment of this utility model: both the front and rear ends of the right side of the top of the platform plate are fixedly connected to a fixing plate, and an unwinding roller is rotatably connected to the top of the side of the fixing plate that is close to it.

[0010] As a further preferred embodiment of this utility model: a filter screen is provided on the top of the platform plate, the top of the filter screen is slidably connected to the scraping strip, and a collection hopper is provided at the bottom of the filter screen.

[0011] As a further preferred embodiment of this utility model: a liquid pump is fixedly connected to the bottom right side of the platform plate, a liquid pumping pipe is fixedly connected to the input end of the liquid pump, and the left end of the liquid pumping pipe is fixedly connected to the bottom of the collection hopper.

[0012] As a further preferred embodiment of this utility model: the output end of the liquid pump is fixedly connected to a drain pipe, the top of the drain pipe is fixedly connected to the dyeing box, the top center right side of the platform plate is fixedly connected to the dyeing box, and multiple guide limit rods are rotatably connected inside the dyeing box.

[0013] As a further preferred embodiment of this utility model: a support plate is fixedly connected to the rear left side of the platform plate, and a movable support plate is slidably connected to the front left side of the platform plate.

[0014] The beneficial effects of this utility model are:

[0015] First, pour an appropriate amount of resin solution into the dyeing box. Then, pass one end of the composite fiber strip on the outer wall of the unwinding roller through the guide limit rod, then through the two guide slip rings at the top of the movable block, and finally fix it to the outer wall of the take-up roller. Next, start the rotary motor to drive the reciprocating screw to rotate. The rotation of the reciprocating screw drives the movable block on the outer wall to move back and forth, thereby moving the composite fiber strip inside the guide slip ring at the top of the movable block. While the rotary motor drives the reciprocating screw to rotate, it also drives the drive gear on the rear side to rotate. The rotation of the drive gear drives the gear timing belt to rotate, which in turn drives the driven gear on the left side to rotate, and the rotation of the driven gear drives the locking block. The rotation of the rotating block drives the take-up roller, ensuring the stability of the take-up. After the composite fiber belt is impregnated with resin, it will be wound up following the rotation of the take-up roller. During the winding process, resin may drip. The moving block moves back and forth with the reciprocating screw, which in turn moves the scraping strip at the bottom of the moving block back and forth. This scrapes the resin dripping from the outer wall of the composite fiber belt during transmission. The resin is then filtered by the filter screen and filter plate at the bottom of the inner wall of the scraping strip and transferred to the collection hopper. The collection hopper is then emptied through the suction pipe at the input end of the suction pump, and the resin is discharged back into the impregnation box through the discharge pipe at the output end of the suction pump for reuse.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0025] refer to Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, a composite fiber winding machine for high-pressure vessels of composite materials includes a platform plate 1. Support connecting plates 18 are fixedly connected to both the front and rear sides of the top center of the platform plate 1. A rotary motor 10 is fixedly connected to the front end of the support connecting plate 18. A reciprocating screw 17 is fixedly connected to the output end of the rotary motor 10. Two guide rods 16 are fixedly connected between the support connecting plates 18 and the movable block 9 of the platform plate 1. The outer walls of the guide rods 16 are slidably connected to the movable block 9. The movable block 9 is threadedly connected to the outer wall of the reciprocating screw 17. A scraping strip 20 is fixedly connected to the bottom of the movable block 9. Two guide slip rings 1 are fixedly connected to the top of the movable block 9. 9. A drive gear 25 is fixedly connected to the rear end of the reciprocating screw 17. A gear timing belt 24 is meshed with the outer wall of the drive gear 25. A driven gear 22 is meshed with the inner wall of the left side of the gear timing belt 24. The outer wall of the driven gear 22 is rotatably connected to the support plate 4. A snap-fit ​​groove 23 is opened inside the driven gear 22. A snap-fit ​​block 21 is snapped inside the snap-fit ​​groove 23. A take-up roller 6 is fixedly connected to the front end of the snap-fit ​​block 21. The front end of the take-up roller 6 is rotatably connected to the movable support plate 7. Two telescopic spring rods 8 are fixedly connected to the bottom front end of the movable support plate 7. The end of the telescopic spring rod 8 away from the movable support plate 7 is fixedly connected to the platform plate 1.

[0026] First, start the rotating motor 10 to rotate. The rotation of the rotating motor 10 drives the reciprocating screw 17 to rotate. The rotation of the reciprocating screw 17 drives the movable block 9 on the outer wall to move back and forth. The two guide rods 16 fixed between the support connecting plates 18 can guide and limit the movable block 9. The back and forth movement of the movable block 9 can drive the composite fiber belt to move and also drive the scraping strip 20 at the bottom to move, scraping the resin dripping from the outer wall of the composite fiber belt. When it is necessary to remove the take-up roller 6, first pull the movable support plate 7 to move the movable support plate 7 forward, so that the movable support plate 7 compresses the telescopic spring rod 8. Then, the front end of the take-up roller 6 is disengaged from the inside of the movable support plate 7. Then, the locking block 21 at the rear end of the take-up roller 6 is pulled out from the locking groove 23 inside the driven gear 22. The take-up roller 6 can be removed and a replacement take-up roller 6 can be placed on it.

[0027] refer to Figure 1 , Figure 2 , Figure 4 As shown, fixed plates 2 are fixedly connected to the front and rear ends of the top right side of the platform plate 1. A roll-up roller 3 is rotatably connected to the top of the fixed plate 2 on the side close to it. A filter screen plate 26 is set on the top of the platform plate 1. The top of the filter screen plate 26 is slidably connected to the scraping strip plate 20. A collection hopper 11 is set at the bottom of the filter screen plate 26. A liquid pump 13 is fixedly connected to the bottom right side of the platform plate 1. A liquid pump pipe 15 is fixedly connected to the input end of the liquid pump 13. The left end of the liquid pump pipe 15 is fixedly connected to the bottom of the collection hopper 11. A drain pipe 14 is fixedly connected to the output end of the liquid pump 13. The top of the drain pipe 14 is fixedly connected to the dyeing box 12. A dyeing box 12 is fixedly connected to the middle right side of the top of the platform plate 1. Multiple guide limit rods 5 are rotatably connected inside the dyeing box 12. A support plate 4 is fixedly connected to the rear left side of the platform plate 1. A movable support plate 7 is slidably connected to the front left side of the platform plate 1.

[0028] By providing a filter screen 26, the resin liquid can be filtered when the scraping strip 20 scrapes it, ensuring that there are no impurities in the resin liquid transmitted to the collection hopper 11. The collection hopper 11 is then drawn through the suction pipe 15 at the input end of the suction pump 13, and then the resin liquid is discharged into the dyeing box 12 through the discharge pipe 14 at the output end of the suction pump 13 for reuse.

[0029] Working principle:

[0030] First, pour an appropriate amount of resin solution into the dyeing box 12. Then, pass one end of the composite fiber belt on the outer wall of the unwinding roller 3 through the guide limiting rod 5, then through the two guide slip ring sleeves 19 at the top of the movable block 9, and finally fix it to the outer wall of the take-up roller 6. Next, start the rotary motor 10 to drive the reciprocating screw 17 to rotate. The rotation of the reciprocating screw 17 drives the movable block 9 on the outer wall to move back and forth. Thus, the movement of the movable block 9 drives the composite fiber belt inside the guide slip ring sleeve 19 at its top to move. While the rotary motor 10 drives the reciprocating screw 17 to rotate, it also drives the rear drive gear 25 to rotate. The rotation of the drive gear 25 drives the gear timing belt 24 to rotate. The rotation of the gear timing belt 24 drives the driven gear 22 on the left to rotate. The rotation of the driven gear 22 drives the driven gear 22 to rotate. The locking block 21 rotates, thereby driving the winding roller 6 to rotate, ensuring the stability of the winding roller 6. After the composite fiber belt is impregnated with resin, it will be wound up following the rotation of the winding roller 6. During the winding process, resin may drip. The movable block 9 moves back and forth with the reciprocating screw 17, which drives the scraping strip 20 at the bottom of the movable block 9 to move back and forth. This scrapes the resin dripping from the outer wall of the composite fiber belt during the transmission process. The resin is then filtered by the filter screen and filter plate 26 at the bottom of the inner wall of the scraping strip 20 and transferred to the collection hopper 11. Then, the collection hopper 11 is drawn out by the suction pipe 15 at the input end of the suction pump 13, and the resin is discharged back into the impregnation box 12 through the discharge pipe 14 at the output end of the suction pump 13 for reuse.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
