Description

Technical Field

[0001] This utility model belongs to the field of impregnation modules, and in particular relates to a side-feed impregnation module for long glass fiber reinforced engineering plastics. Background Technology

[0002] Impregnation is a process technology that involves immersing a solid material in a liquid, allowing the liquid to penetrate and adhere to the surface or interior of the solid. It is widely used in materials preparation, chemical industry, textiles and other fields. When reinforcing glass fiber, the fluidity and permeability of thermoplastic resin melt (such as polystyrene PS) can be utilized to allow the melt to penetrate into the pores, cracks or surface of the solid material under certain temperature and pressure conditions, thereby achieving purposes such as coating, modification, filling or interfacial bonding, and thus optimizing the mechanical properties of glass fiber.

[0003] In the prior art, during the impregnation of glass fiber reinforced with engineering plastics, the impregnation module usually does not have a limiting and guiding structure, which makes it easy for the glass fiber to agglomerate during the conveying process. As a result, the glass fiber cannot be uniformly impregnated by the melt, affecting the quality of the glass fiber reinforcement. To address this issue, we provide a side-feed impregnation module for long glass fiber reinforced engineering plastics to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a side-feeding impregnation module for long glass fiber reinforced engineering plastics, in order to solve the problem that glass fiber is prone to agglomeration during the conveying process, which leads to the glass fiber not being uniformly impregnated by the melt and affects the quality of the glass fiber reinforced product.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a side-feeding impregnation module for long glass fiber reinforced engineering plastics, comprising a module, a disassembly and assembly structure, a limiting structure, a guiding structure, and an adjustment structure. The disassembly and assembly structure includes a connecting cover movably connected to the module, multiple positioning blocks fixedly connected to the module, a threaded rod fixedly connected to the upper surface of the positioning block, a nut movably connected to the outer surface of the threaded rod and fixedly connected to the connecting cover on the connecting plate, and a nut threadedly connected to the outer surface of the connecting plate. The limiting structure includes two connecting rods fixedly connected to the module, two connecting shafts rotatably connected to the inner surface of the connecting rods, positioning rods fixedly connected to the two connecting shafts, multiple positioning grooves opened on the positioning rods, a guiding structure provided on the module, and an adjustment structure provided on the module.

[0007] Preferably, the guide structure includes two upper guide rods fixedly connected to the module, two lower guide rods fixedly connected to the module, a plurality of first guide grooves formed on the upper guide rods, and a plurality of second guide grooves formed on the lower guide rods.

[0008] Preferably, the module is provided with an inlet and an outlet to ensure that the glass fiber can pass through the module smoothly for impregnation.

[0009] Preferably, a melt inlet pipe is fixedly connected to the module, so that the melt can smoothly enter the mold cavity.

[0010] Preferably, the nut has a connecting groove for threaded connection with the threaded rod.

[0011] Preferably, the connecting plate has a threaded rod movable connection hole, which facilitates the initial connection between the connecting cover and the module.

[0012] Preferably, a limiting ring is fixedly connected to the outer surface of the connecting shaft, and a limiting groove is provided on the connecting rod to rotatably connect with the limiting ring, so that the connecting shaft can rotate smoothly while ensuring that the connecting shaft will not move arbitrarily.

[0013] Preferably, the module has an impregnation cavity, and the limiting structure is two in number and symmetrically distributed.

[0014] Preferably, the adjustment structure includes two L-shaped rods fixedly connected to the module, a bearing plate fixedly connected to the L-shaped rods, a threaded screw threaded to the inner surface of the bearing plate, a limiting block rotatably connected to the inner surface of the threaded screw, a lifting plate fixedly connected to the lower surface of the limiting block, two guide blocks fixedly connected to the lifting plate, two lifting rods fixedly connected to the lower surface of the lifting plate, two rotating rods rotatably connected to the inner surfaces of the two lifting rods respectively, two anti-detachment rings fixedly connected to the outer surfaces of the two rotating rods respectively, a traction cylinder fixedly connected to the two rotating rods, a plurality of traction grooves opened on the traction cylinders, and a rotating block fixedly connected to the upper surface of the threaded screw.

[0015] Preferably, the L-shaped rod has a lifting groove that is slidably connected to the guide block, and the lifting rod has an anti-detachment groove that is rotatably connected to the anti-detachment ring.

[0016] This utility model has the following beneficial effects:

[0017] 1. The positioning rod, positioning groove, upper guide rod, and lower guide rod structure provide guidance and limit during the fiberglass traction process, preventing fiberglass from agglomerating during impregnation and ensuring the quality of the impregnated fiberglass. The positioning rod and traction cylinder can rotate, improving the stability of the fiberglass traction and conveying process. Furthermore, by operating the rotating block, the height and position of the traction cylinder and traction groove can be adjusted, allowing the device to regulate tension according to the length and thickness of different fiberglass fibers. This prevents damage to the fiberglass due to improper tension and ensures the performance of the final product.

[0018] 2. Through the design of the threaded rod, connecting plate and nut, the connecting cover can be removed by unscrewing the nut from the threaded rod. This allows the connecting cover to be removed from the module. Once the connecting cover is removed, it not only facilitates the initial traction of the fiberglass, but also allows for cleaning and maintenance of the module's interior in the later stages.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. Specific Implementation Example 1

[0031] like Figures 1-6 As shown, this utility model is a side-feeding impregnation module for long glass fiber reinforced engineering plastics, including module 1, disassembly and assembly structure, limiting structure, guiding structure and adjustment structure.

[0032] like Figures 1-3 As shown, in this embodiment, the disassembly and assembly structure includes a connecting cover 2 movably connected to module 1, multiple positioning blocks 3 fixedly connected to module 1, a threaded rod 4 fixedly connected to the upper surface of the positioning block 3, a nut 6 movably connected to the outer surface of the threaded rod 4 and fixedly connected to the connecting cover 2 on the connecting plate 5, and threadedly connected to the outer surface of the connecting plate 5. The nut 6 has a connecting groove 18 threadedly connected to the threaded rod 4, and the connecting plate 5 has a mating hole 19 movably connected to the threaded rod 4. The module 1 has an inlet 15 and an outlet 16 respectively, a melt inlet pipe 17 fixedly connected to the module 1, and an impregnation chamber 22.

[0033] In this embodiment, by rotating the nut 6 and unscrewing it from the threaded rod 4, the fixing of the connecting cover 2 can be released. At this time, the connecting cover 2 can be lifted upwards to remove the connecting cover 2 and the structure on the connecting cover 2 from the module 1. After the connecting cover 2 is removed, it is convenient to perform the initial traction of the glass fiber and to clean and maintain the structure inside the module 1 later. The connecting plate 5 is inserted into the threaded rod 4 through the mating hole 19 on the connecting plate 5, and then the nut 6 is screwed back onto the threaded rod 4 through the connecting groove 18 on the nut 6 and tightened, thereby completing the connection and fixing between the module 1 and the connecting cover 2. Specific Implementation Example 2

[0035] like Figures 1-6 As shown, this utility model is a side-feeding impregnation module for long glass fiber reinforced engineering plastics. Compared with Embodiment 1, in this embodiment, the limiting structure includes two connecting rods 7 fixedly connected to the module 1, two connecting shafts 8 rotatably connected to the inner surface of the connecting rods 7, positioning rods 9 fixedly connected to the two connecting shafts 8, multiple positioning grooves 10 opened on the positioning rods 9, a guide structure set on the module 1, and an adjustment structure set on the module 1. A limiting ring 20 is fixedly connected to the outer surface of the connecting shaft 8, and a limiting groove 21 rotatably connected to the limiting ring 20 is opened on the connecting rod 7. The number of limiting structures is two and they are symmetrically distributed.

[0036] The guide structure includes two upper guide rods 11 fixedly connected to module 1, two lower guide rods 12 fixedly connected to module 1, a plurality of first guide grooves 13 formed on the upper guide rods 11, and a plurality of second guide grooves 14 formed on the lower guide rods 12.

[0037] The adjustment structure includes two L-shaped rods 23 fixedly connected to module 1, a bearing plate 24 fixedly connected to the L-shaped rods 23, a threaded rod 25 threadedly connected to the inner surface of the bearing plate 24, a limiting block 26 rotatably connected to the inner surface of the threaded rod 25, a lifting plate 27 fixedly connected to the lower surface of the limiting block 26, two guide blocks 28 fixedly connected to the lifting plate 27, two lifting rods 29 fixedly connected to the lower surface of the lifting plate 27, two rotating rods 30 rotatably connected to the inner surfaces of the two lifting rods 29, two anti-detachment rings 31 fixedly connected to the outer surfaces of the two rotating rods 30, a traction cylinder 35 fixedly connected to the two rotating rods 30, multiple traction grooves 36 formed on the traction cylinders 35, and a rotating block 34 fixedly connected to the upper surface of the threaded rod 25. The L-shaped rods 23 are provided with lifting grooves 33 that are slidably connected to the guide blocks 28, and the lifting rods 29 are provided with anti-detachment grooves 32 that are rotatably connected to the anti-detachment rings 31.

[0038] In this embodiment, during the initial traction of the glass fiber, different glass fibers are passed through different traction grooves 36 on the traction cylinder 35. During the traction process, different glass fibers are also placed in different positioning grooves 10 on the positioning rod 9. At this time, the traction grooves 36 and positioning grooves 10 can limit the movement of the glass fibers, preventing adjacent glass fibers from contacting each other. Furthermore, the upper guide rod 11 and lower guide rod 12 are also provided with first guide grooves 13 and second guide grooves 14 corresponding to the positioning grooves 10, thereby preventing the glass fibers from agglomerating in the impregnation cavity 22. When the glass fiber traction is successfully completed, the effect is as follows: Figure 6 As shown, the melt is then conveyed into the impregnation chamber 22 within module 1 through the melt inlet pipe 17. As the melt gradually enters the impregnation chamber 22, it comes into contact with the glass fiber inside, thus impregnating the glass fiber. At this point, the glass fiber conveying and traction can begin. The positioning rod 9 is rotatably connected to the connecting rod 7 via the connecting shaft 8, and the traction cylinder 35 is rotatably connected to the lifting rod 29 via the rotating rod 30. This converts the sliding friction between the glass fiber and the positioning rod 9 and the traction cylinder 35 into rolling friction, reducing the friction between the glass fiber and the positioning rod 9 and the traction cylinder 35. The resistance to conveying is reduced, improving the stability of glass fiber conveying. By rotating the rotating block 34, the threaded screw 25 can be rotated. At this time, the rotating threaded screw 25, under the action of the threads between the bearing plates 24, drives the threaded screw 25 and the rotating block 34 to move downward or upward. In turn, the moving threaded screw 25 can drive the limiting block 26, the lifting plate 27 and the structure on the lifting plate 27 to move up and down. At this time, the height position of the traction cylinder 35 and the traction groove 36 can be changed, thereby changing the tension of the glass fiber during traction.
