Description

Technical Field

[0001] This invention relates to the field of fiber composite material processing equipment, and in particular to a fiber reinforced composite material winding and pressing molding device. Background Technology

[0002] Fiber-reinforced polymer (FRP) is a composite material formed by combining reinforcing fiber materials (such as glass fiber, carbon fiber, aramid fiber, etc.) and a matrix material through specific molding processes (such as winding, compression molding, pultrusion, etc.). Reinforcing fiber materials: primarily responsible for reinforcement, including glass fiber, carbon fiber, aramid fiber, etc. These fiber materials possess excellent properties such as high strength and high modulus. Matrix materials: typically resin-based materials, such as epoxy resin, phenolic resin, etc. The matrix material bonds the reinforcing fibers together to form an integral structure. Fiber-reinforced polymer (FRP) winding and compression molding equipment is used to produce high-performance composite materials. It is a production device integrating fiber winding, resin impregnation, and pressure molding. It utilizes high-strength, high-modulus fiber reinforcing materials (such as carbon fiber, glass fiber, etc.) and a resin matrix through specific processes to form composite material products with excellent properties.

[0003] A search revealed Chinese patent CN211843289U, which discloses a fiber-reinforced composite material extrusion molding device. The device includes two sets of fixed side plates, each rectangular in shape and corresponding to the other. A drive roller, with an S-shaped surface area, is movably connected to the middle of the two sets of fixed side plates via a movable shaft. An auxiliary side plate, also rectangular in shape, is fixedly mounted on the upper end of each fixed side plate. A groove, also rectangular in shape, is formed in the middle of the auxiliary side plate. A slider, rectangular in shape, is slidably connected inside the groove. The product is extruded and molded by the mutual contact and compression of the auxiliary and drive rollers. By designing the outer surfaces of the auxiliary and drive rollers as S-shaped, the contact area between the drive and auxiliary rollers and the product is increased, thereby improving the extrusion molding efficiency.

[0004] However, in actual use, the above-mentioned device cannot heat the extruded material during the extrusion process. If the extrusion process is too long, some materials may solidify prematurely, affecting the appearance of the subsequent molding and reducing the working efficiency of the device. Moreover, during the winding and extrusion process, some fiber materials may fall outside the device. If not handled in time, the fallen fiber materials will solidify outside the device and be difficult to clean, resulting in low functionality of the device. Therefore, a fiber-reinforced composite material winding and pressing molding device is proposed. Summary of the Invention

[0005] The purpose of this invention is to solve the problems in the prior art, such as the inability to heat the extruded material during the extrusion process, the possibility that the material may solidify prematurely due to the excessively long extrusion process, which affects the appearance of the subsequent molding and reduces the working efficiency of the device. In addition, some fiber material may fall outside the device during the winding and extrusion process. If not handled in time, the fallen fiber material will solidify outside the device and be difficult to clean, resulting in low functionality of the device. Therefore, this invention proposes a fiber reinforced composite material winding and pressing molding device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A fiber-reinforced composite material winding and pressing molding device includes a base, a substrate fixedly connected to the outside of the base, a heating mechanism disposed inside the substrate, the heating mechanism including a first motor disposed inside the substrate, a threaded rod disposed at the output end of the first motor, a moving plate being drivenly connected to the outside of the threaded rod, multiple sets of fans disposed outside the moving plate, a heating tube fixedly connected to the outside of the substrate, the operation of the heating mechanism causing the multiple sets of fans to blow the heat generated by the heating tube to the outside of the composite material at different positions, a winding mechanism disposed outside the base, and an extrusion mechanism disposed outside the base;

[0008] The base is equipped with a cleaning mechanism, which includes a second motor installed inside the base. The output end of the second motor is equipped with a gear, which is externally connected to a rack and pinion belt. A transmission rod is fixedly connected to the outside of the rack and pinion belt. A push plate is fixedly connected to the side of the transmission rod away from the rack and pinion belt. The operation of the cleaning mechanism causes the push plate to change from a stationary state to a moving state.

[0009] The above technical solution further includes:

[0010] The base plate is fixedly connected to the first motor. A square groove is provided inside the base plate. The first motor is fixedly installed inside the square groove. The threaded rod is rotatably connected to the square groove.

[0011] The external threaded connection is to a threaded cylinder, which is slidably connected to the base plate. A connecting rod is fixedly connected to the outside of the threaded cylinder, and the connecting rod is fixedly connected to the movable plate.

[0012] The substrate has a groove inside, and a sliding member is slidably connected inside the groove. The sliding member is fixedly connected to the moving plate.

[0013] The winding mechanism includes a winding bracket disposed outside the base, the base and the winding bracket being fixedly connected, a fiber supply box being fixedly connected to the side of the winding bracket away from the base, and a mandrel rotation assembly disposed outside the winding bracket.

[0014] The extrusion mechanism includes a support frame disposed outside the base, the base and the support frame being fixedly connected, an extrusion transmission assembly disposed inside the support frame, and an extrusion roller being drivenly connected to the extrusion transmission assembly.

[0015] An organic groove is provided inside the base, the second motor is located inside the groove, and a filter plate is fixedly connected inside the base.

[0016] The rack belt is internally connected to a gear rod, which is rotatably connected to the slot.

[0017] A waste collection box is fixedly connected inside the base, and a wastewater tank is fixedly connected outside the base.

[0018] A nozzle is fixedly installed inside the base, and the nozzle is capable of spraying water.

[0019] The present invention has the following beneficial effects:

[0020] 1. In this invention, when the extrusion mechanism is running, the first motor controls the rotation of the threaded rod, which drives the threaded cylinder to move. The threaded cylinder drives the connecting rod to move, which drives the moving plate to move. The moving plate drives multiple sets of fans to move. The multiple sets of fans transfer the heat generated by the heating tubes to the outside of the composite material being extruded. During the extrusion process, the material being extruded can be heated at different locations, so that the composite material is always kept at a high temperature during the extrusion process. This prevents the situation where some materials solidify and form prematurely due to excessively long extrusion time, and does not affect the subsequent molding of the fiber and resin composite material, thereby improving the working efficiency of the device.

[0021] 2. In this invention, when the winding mechanism and the extrusion mechanism are running, the second motor controls the gear to rotate, the gear drives the rack belt to rotate, the rack belt drives the transmission rod to move, and the transmission rod drives the push plate to slide outside the filter plate. The fallen material is cooled and solidified by multiple sets of nozzles and falls outside the filter plate. The push plate pushes the fallen material into the waste collection box. This can cool and solidify some of the fiber material that falls off during the winding and extrusion process and collect it, preventing the fallen fiber material from solidifying outside the device and becoming difficult to clean. This facilitates the subsequent cleaning work of the staff, is beneficial to the long-term use of the device, and enhances the functionality of the device. Attached Figure Description

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Example 1

[0031] like Figure 1-6 As shown, the fiber-reinforced composite material winding and pressing molding device proposed in this invention includes a base 1, a base plate 2 fixedly connected to the outside of the base 1, a heating mechanism inside the base plate 2, a first motor 4 inside the base plate 2, a threaded rod 5 at the output end of the first motor 4, a moving plate 8 externally connected to the threaded rod 5, multiple sets of fans 9 externally connected to the moving plate 8, and a heating tube 10 fixedly connected to the outside of the base plate 2. The operation of the heating mechanism causes the multiple sets of fans 9 to blow the heat generated by the heating tube 10 to the outside of the composite material at different positions. A winding mechanism and an extrusion mechanism are provided outside the base 1.

[0032] The base 1 is equipped with a cleaning mechanism, which includes a second motor 20 installed inside the base 1. The output end of the second motor 20 is equipped with a gear 21. The gear 21 is externally meshed with a rack belt 22. The rack belt 22 is externally fixedly connected to a transmission rod 23. The side of the transmission rod 23 away from the rack belt 22 is fixedly connected to a push plate 24. The operation of the cleaning mechanism causes the push plate 24 to change from a stationary state to a moving state.

[0033] The substrate 2 is fixedly connected to the first motor 4. A square groove 3 is provided inside the substrate 2. The first motor 4 is fixedly installed inside the square groove 3. The threaded rod 5 is rotatably connected to the square groove 3.

[0034] The threaded cylinder 6 is externally threaded and is slidably connected to the base plate 2. The threaded cylinder 6 is externally fixedly connected to the connecting rod 7, and the connecting rod 7 is fixedly connected to the movable plate 8.

[0035] An organic tank 19 is provided inside the base 1, and a second motor 20 is provided inside the machine tank 19. A filter plate 25 is fixedly connected inside the base 1.

[0036] The rack belt 22 is internally connected to a gear rod 26, which is rotatably connected to the slot 19.

[0037] A waste collection box 27 is fixedly connected inside the base 1, and a wastewater tank 28 is fixedly connected outside the base 1.

[0038] A nozzle 29 is fixedly installed inside the base 1, and the nozzle 29 can spray water.

[0039] In this embodiment, a base plate 2 is fixedly connected to the outside of the base 1. The heating mechanism set inside the base plate 2 is activated, and the first motor 4 in the heating mechanism starts to run. The first motor 4 is fixed inside the square groove 3 opened inside the base plate 2. When the first motor 4 runs, it controls the threaded rod 5 set at its output end to start rotating. The other side of the threaded rod 5 drives the inside of the threaded cylinder 6 to rotate inside the square groove 3. When the threaded rod 5 rotates inside the threaded cylinder 6, it generates spiral power and drives the threaded cylinder 6 to start moving. Since there is a sliding connection between the outside of the threaded cylinder 6 and the inside of the square groove 3, the threaded cylinder 6 will not rotate. When the threaded cylinder 6 moves, it drives the connecting rod 7 to start moving. The other side of the connecting rod 7 drives the moving plate 8 to start moving. Multiple sets of fans 9 are set outside the moving plate 8. When the moving plate 8 moves, it drives the multiple sets of fans 9 to start running at different positions. A heating tube 10 is fixedly connected inside the base plate 2. When the heating tube 10 runs, it generates a lot of heat. The multiple sets of fans 9 start blowing the heat to the outside of the extrusion mechanism at different positions, so that the temperature of the composite material being extruded by the extrusion mechanism will not decrease.

[0040] When the winding and extrusion mechanisms are running, the cleaning mechanism inside the base 1 is activated. A machine groove 19 is created inside the base 1, and the second motor 20, fixedly installed inside the machine groove 19, begins to operate. When the second motor 20 runs, it controls the gear 21 at its output end to rotate. The rotation of the gear 21 drives the rack belt 22, which meshes with its external parts, to rotate. The rotation of the rack belt 22, in turn, drives the gear rod 26, which meshes with its other side, to rotate. The other side of the gear rod 26 then rotates inside the machine groove 19, ensuring the stability of the rack belt 22 during rotation. The rotation of the rack belt 22 also drives the transmission rod 23, fixedly connected to its external parts, to move. When the transmission rod 23 moves, it drives the push plate 24 on the other side to move. A filter plate 25 is fixedly connected inside the base 1. When the unsolidified material box on the winding mechanism and the extrusion mechanism falls into the base 1, multiple sets of nozzles 29 fixedly installed inside the base 1 start spraying water, so that the unsolidified material solidifies when it falls onto the surface of the filter plate 25. At this time, the push plate 24 starts to slide inside the filter plate 25 and pushes the excess material to the other side of the base 1. A waste collection box 27 is fixedly connected to the other side of the base 1. The excess material is collected inside the waste collection box 27. The wastewater enters the wastewater tank 28 fixedly connected to the bottom of the base 1 through the inside of the filter plate 25, completing the cleaning and collection of the fallen material.

[0043] The winding mechanism includes a winding bracket 13 disposed outside the base 1, the base 1 and the winding bracket 13 are fixedly connected, a fiber supply box 14 is fixedly connected to the side of the winding bracket 13 away from the base 1, and a core mold rotation assembly 15 is disposed outside the winding bracket 13.

[0044] The extrusion mechanism includes a support frame 16 disposed outside the base 1, the base 1 and the support frame 16 being fixedly connected, and an extrusion transmission assembly 17 disposed inside the support frame 16, the extrusion transmission assembly 17 being drivenly connected to an extrusion roller 18.

[0045] In this embodiment, when the moving plate 8 moves, it drives the sliding member 12, which is fixedly connected to its exterior, to move. The other side of the sliding member 12 is slidably connected to the groove 11 opened inside the substrate 2. The sliding member 12 begins to slide inside the base 1. Two sets of grooves 11 and sliding members 12 are provided to ensure the stability of the heating mechanism during operation. The winding bracket 13 in the winding mechanism is fixed to the outside of the base 1. The fiber supply box 14 fixed inside the winding bracket 13 is responsible for supplying fiber reinforcing material to the outside of the resin substrate. The mandrel rotation assembly 15 is responsible for rotating the resin substrate fixed to its exterior, so that the winding work can be carried out smoothly. The support frame 16 in the extrusion mechanism is fixedly installed on the other side of the base 1. The extrusion transmission assembly 17 provided inside the support frame 16 is responsible for controlling the rotation of the extrusion roller 18 and adjusting its height, so as to extrude and mold the composite material of resin and fiber winding.
