Description

Technical Field

[0001] This invention relates to the field of composite material molding technology, and more specifically, to a thermoplastic molding apparatus for composite photovoltaic bracket components. Background Technology

[0002] As the photovoltaic industry increasingly demands lower system costs, higher installation efficiency, and enhanced environmental durability, the use of fiber-reinforced composite materials (especially continuous fiber-reinforced thermoplastic composites) to manufacture photovoltaic brackets has become an important trend. These materials have advantages such as light weight, high strength, corrosion resistance, maintenance-free operation, and recyclability, and are significantly superior to traditional steel and aluminum brackets. Pultrusion is an efficient process for the continuous production of composite profiles with constant cross-sections, and it is very suitable for producing long strip components such as beams and columns of photovoltaic brackets. However, existing pultrusion molding equipment for thermoplastic composites has certain technical defects in practical implementation: First, the fiber tensioning mechanism of existing pultrusion equipment is usually only mechanically adjustable, which can only provide constant or coarsely adjustable tension, making it difficult to achieve dynamic and precise tension control. Moreover, it has a single function, only responsible for tensioning and does not have the ability to pre-treat the fibers. Secondly, existing impregnation tanks or simple injection methods can easily lead to uneven distribution of resin in the width and thickness directions of fiber bundles. Air can easily be trapped inside the fiber bundles, forming "dry spots" or pores, which seriously affect the mechanical properties of the products. Third, the existing technology uses a fixed-position injection tube or injection nozzle, which easily causes the resin to be concentrated on a certain line of the fiber bundle, resulting in uneven distribution of resin in the width direction, which is particularly unfavorable for wide products. In view of this, the present invention proposes a thermoplastic molding device for composite photovoltaic bracket components. Summary of the Invention

[0003] This invention proposes a thermoplastic molding device for composite photovoltaic bracket components, which solves the problem that the resin is easily unevenly distributed in the fiber bundle width and thickness directions due to impregnation tanks or simple glue injection methods in the prior art.

[0005] Preferably, a copper tube is fixedly connected to the inner side of the tensioning roller, and a heating wire is fixedly connected to the inner side of the copper tube.

[0006] Preferably, the in-situ liquid impregnation mechanism includes a sealed impregnation chamber fixedly connected to the top of the frame. One end of the sealed impregnation chamber has a fiber inlet, and the other end has a fiber outlet. A plurality of guide rollers arranged vertically and horizontally are rotatably connected to the inner side of the sealed impregnation chamber. A second motor is fixedly installed on the outer side of the sealed impregnation chamber. The output shaft of the second motor is fixedly connected to one of the guide rollers. Two parallel glue guide tubes are rotatably connected to the top of the inner side of the sealed impregnation chamber. A plurality of glue injection nozzles arranged axially are fixedly connected to the bottom ends of the two glue guide tubes.

[0007] Preferably, the top of the sealed impregnation chamber is provided with a negative pressure component, including a wind duct fixedly connected to the top of the sealed impregnation chamber. A mounting frame is fixedly connected to the top of the wind duct. An air suction impeller is rotatably connected to the inner side of the mounting frame. A third motor is fixedly installed on the top of the mounting frame. The output shaft of the third motor is fixedly connected to the air suction impeller. A transmission component is provided on the outer side of the sealed impregnation chamber to drive the two guide tubes to reciprocate by cooperating with the start of the third motor.

[0008] Preferably, the transmission component includes a rotating shaft rotatably connected to the top of the sealed impregnation chamber, one end of the rotating shaft being fixedly connected to a first bevel gear, and the output shaft of the third motor being fixedly connected to a second bevel gear meshing with the first bevel gear.

[0009] Preferably, the ratio of the number of teeth of the first bevel gear to the number of teeth of the second bevel gear is 4:1.

[0010] Preferably, the transmission component further includes an eccentric wheel fixedly connected to the other end of the rotating shaft, a slide rail fixedly connected to the outer side of the sealed impregnation chamber, a slider slidably connected to the outer side of the slide rail, a connecting rod hinged to the top of the slider, and the end of the connecting rod away from the slider being rotatably connected to the outer edge of the eccentric wheel.

[0011] Preferably, a toothed plate is fixedly connected to the bottom of the slider, a first spur gear is fixedly connected to one end of each of the two guide tubes, and a second spur gear is rotatably connected to the outside of the sealed impregnation chamber, with the two ends of the second spur gear meshing with the two first spur gears respectively.

[0012] Preferably, a support is fixedly connected to the outside of the sealed impregnation chamber, and two pipe joints are fixedly connected to the top of the support. The two pipe joints are rotatably connected to the inlet ends of two glue guide tubes, and glue delivery tubes are fixedly connected to the inlet ends of the two pipe joints.

[0013] Preferably, the inlet end of the glue delivery tube is connected to a glue supply device.

[0014] The working principle and beneficial effects of this invention are as follows: 1. The position of the tension roller can be precisely adjusted by driving the movable seat with a cylinder, thereby dynamically controlling the fiber tension and ensuring stable and uniform fiber bundle tension during the impregnation and molding stages, resulting in high performance. The tension roller integrates heating wires and copper tubes, which can preheat the fibers while tensioning. This design removes moisture from the fiber surface and reduces the viscosity of the thermoplastic resin melt during subsequent impregnation, significantly improving the resin's wettability to the fibers and reducing "dry spots" and porosity defects inside the product from the source.

[0015] 2. By setting up staggered guide rollers in the sealed impregnation chamber, the fibers travel in a serpentine pattern, which greatly increases the contact area and contact time between the resin and the fibers, promoting full impregnation; the negative pressure generated in the impregnation chamber by the negative pressure component (suction impeller) can effectively extract the air between the fiber bundles and the air bubbles generated during the impregnation process, strongly promoting the penetration of resin into the fiber interior, greatly reducing the porosity of the finished product, and improving the density and mechanical strength of the material.

[0016] 3. Through a clever transmission mechanism, the same motor that drives the negative pressure component drives the injection nozzle to swing back and forth in the fiber width direction. This breaks the problem of uneven resin distribution caused by fixed-point injection and realizes transverse scanning injection of fiber bundles (especially wide products), ensuring that the resin is evenly distributed in the width and thickness directions.

[0017] 4. A rotating and sealed connection between the fixed glue supply line and the oscillating glue guide tube is achieved through a pipe fitting, ensuring the continuity and sealing of glue supply during the continuous oscillation of the glue nozzle and maintaining process stability.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. 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 of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0022] like Figures 1 to 8 As shown, this embodiment proposes a thermoplastic molding device for a composite photovoltaic bracket component, including a frame 1. One end of the top of the frame 1 is rotatably connected to an unwinding roller 2 for releasing fibers. A mounting frame 3 is fixedly connected to the middle of the frame 1. A feeding roller 4 is rotatably connected to the inner side of the mounting frame 3. A first motor 5 is fixedly installed on the outer side of the mounting frame 3. The output shaft of the first motor 5 is fixedly connected to the feeding roller 4. A tensioning mechanism 8 for tensioning fibers is provided on the inner side of the mounting frame 3. The tensioning mechanism 8 includes two movable seats 81 symmetrically distributed along the center line of the mounting frame 3. The mounting frame 3 has grooves 82 that slide and engage with the two movable seats 81. Cylinders 83 are fixedly connected to the inner side of the two grooves 82. The output ends of the two cylinders 83 are fixedly connected to the corresponding movable seats 81. A tensioning roller 84 is rotatably connected between the two movable seats 81. An in-situ liquid impregnation mechanism 9 for impregnating fibers is provided at the outlet end of the feeding roller 4. An extrusion mold 10 for forming fibers is provided at the outlet end of the in-situ liquid impregnation mechanism 9.

[0023] In this embodiment, continuous fibers are released from the unwinding roller 2 and conveyed forward under the traction of the feeding roller 4. The fibers first pass through the tensioning mechanism 8, which drives the movable seat 81 to move along the slide groove 82 via the cylinder 83, thereby adjusting the position of the tensioning roller 84 to apply and maintain the required tension on the fibers. Subsequently, the fibers with constant tension enter the in-situ liquid impregnation mechanism 9 for resin impregnation. The impregnated fiber bundle is finally fed into the extrusion die 10. Under the heating, compaction and shaping action of the die, the resin is cured, and the fibers are tightly bonded to the resin, continuously extruding a thermoplastic composite profile with a specific cross-section, i.e., a photovoltaic bracket component.

[0024] This design constructs a complete pultrusion production line framework, realizing continuous and automated production from fiber unwinding, tension control, resin impregnation to mold forming. The feed roller 4 provides stable traction power and is the core of continuous production. The tensioning mechanism 8 can dynamically and precisely control the fiber tension to ensure that the fiber bundles entering the impregnation and mold stages are uniformly tight, which is a key prerequisite for obtaining high-performance, uniformly shaped composite profiles.

[0025] In a further preferred embodiment of the present invention, a copper tube 841 is fixedly connected to the inner side of the tension roller 84, and a heating wire 842 is fixedly connected to the inner side of the copper tube 841.

[0026] In this embodiment, while the tensioning mechanism 8 applies mechanical tension to the fiber, the heating wire 842 built into the tensioning roller 84 is activated. The heat generated by the heating wire 842 is efficiently and evenly conducted to the surface of the tensioning roller 84 through the copper tube 841. When the fiber comes into contact with the heated surface of the tensioning roller 84, the fiber is preheated.

[0027] This design preheats the fibers before they enter the impregnation zone. Preheating removes any moisture or low-molecular-weight substances that may be adsorbed on the fiber surface, improving the interfacial bonding between the fiber and the subsequent impregnation resin. Simultaneously, the preheated fibers help reduce the viscosity of certain thermoplastic resin melts when they enter the impregnation chamber, making it easier for the resin to wet and penetrate the fiber bundle. This improves impregnation quality and reduces dry spots or porosity defects inside the product.

[0028] In a further preferred embodiment of the present invention, the in-situ liquid impregnation mechanism 9 includes a sealed impregnation chamber 91 fixedly connected to the top of the frame 1. One end of the sealed impregnation chamber 91 has a fiber inlet 92, and the other end of the sealed impregnation chamber 91 has a fiber outlet 93. A plurality of guide rollers 94 arranged vertically and horizontally are rotatably connected to the inner side of the sealed impregnation chamber 91. A second motor 98 is fixedly installed on the outer side of the sealed impregnation chamber 91. The output shaft of the second motor 98 is fixedly connected to one of the guide rollers 94. Two parallel glue guide tubes 95 are rotatably connected to the top of the inner side of the sealed impregnation chamber 91. A plurality of glue injection nozzles 96 arranged axially are fixedly connected to the bottom end of the two glue guide tubes 95.

[0029] In this embodiment, the fiber enters the sealed impregnation chamber 91 through the fiber inlet 92. Inside the chamber, the fiber sequentially winds around multiple staggered guide rollers 94, forming a serpentine path. A second motor 98 drives one of the guide rollers 94 to rotate slowly, assisting the fiber movement and preventing it from slipping on the guide roller 94. Simultaneously, liquid resin is delivered through the glue guide tube 95 to multiple glue nozzles 96 at its bottom, and is directly sprayed or dripped onto the fiber bundle as it travels through the serpentine path. As the fiber travels along the tortuous path, it is continuously enveloped and impregnated by the resin falling from different positions above.

[0030] The enclosed impregnation chamber 91 of this design provides a controlled environment for resin impregnation, reducing external contamination and resin volatilization. The staggered guide rollers 94 significantly increase the fiber's travel path length within the limited space, extending the resin-fiber contact and wetting time. Multiple axially distributed dispensing nozzles 96 ensure that resin is applied evenly across the width of the fiber bundle, avoiding localized insufficient impregnation.

[0031] In a further preferred embodiment of the present invention, a negative pressure component 97 is provided at the top of the sealed impregnation chamber 91. The negative pressure component 97 includes a duct 971 fixedly connected to the top of the sealed impregnation chamber 91, a mounting bracket 972 fixedly connected to the top of the duct 971, a suction impeller 973 rotatably connected to the inner side of the mounting bracket 972, and a third motor 974 fixedly mounted on the top of the mounting bracket 972. The output shaft of the third motor 974 is fixedly connected to the suction impeller 973. A transmission component 9b is provided on the outer side of the sealed impregnation chamber 91, which drives two guide tubes 95 to reciprocate by cooperating with the start of the third motor 974. The transmission component 9b includes a rotating shaft 9b1 rotatably connected to the top of the sealed impregnation chamber 91, a first bevel gear 9b2 fixedly connected to one end of the rotating shaft 9b1, and the output of the third motor 974... A second bevel gear 9b3, which meshes with a first bevel gear 9b2, is fixedly connected to the shaft. The gear ratio of the first bevel gear 9b2 to the first bevel gear 9b2 is 4:1. An eccentric wheel 9b4 is fixedly connected to the other end of the rotating shaft 9b1. A slide rail 9b5 is fixedly connected to the outside of the sealed impregnation chamber 91. A slider 9b6 is slidably connected to the outside of the slide rail 9b5. A connecting rod 9b7 is hinged to the top of the slider 9b6. The end of the connecting rod 9b7 away from the slider 9b6 is rotatably connected to the outer edge of the eccentric wheel 9b4. A toothed plate 9b8 is fixedly connected to the bottom of the slider 9b6. A first spur gear 9b9 is fixedly connected to one end of each of the two guide tubes 95. A second spur gear 9b0 is rotatably connected to the outside of the sealed impregnation chamber 91. The two ends of the second spur gear 9b0 mesh with the two first spur gears 9b9 respectively.

[0032] In this embodiment, by starting the third motor 974, the suction impeller 973 is driven to rotate, generating negative pressure in the air duct 971 and the sealed impregnation chamber 91. The power of the third motor 974 simultaneously drives the injection tube to swing through the transmission component 9b. The specific path is as follows: The second bevel gear 9b3 on the output shaft of the third motor 974 drives the first bevel gear 9b2 to rotate. Since the gear ratio between the two is 4:1, speed reduction and torque increase are achieved. The rotating shaft 9b1 rotates accordingly, driving the eccentric wheel 9b4 at its end to rotate. The eccentric wheel 9b4, through the connecting rod 9b7, converts the rotational motion into linear reciprocating motion of the slider 9b6 on the slide rail 9b5. The toothed plate 9b8 at the bottom of the slider 9b6 moves back and forth accordingly, driving the second spur gear 9b0, which meshes with it, to rotate alternately in both directions. The second spur gear 9b0 simultaneously meshes with two first spur gears 9b9, thereby driving the two glue guide tubes 95 and their glue injection nozzles 96 to reciprocate synchronously.

[0033] The negative pressure environment inside the impregnation chamber effectively removes air between fiber bundles and bubbles generated during resin impregnation, greatly promoting resin penetration into the fiber bundles and between fiber filaments, significantly reducing porosity in composite products, and improving density and mechanical properties. The reciprocating oscillation of the injection nozzle 96 means that the resin application is no longer a fixed straight line, but a transverse scanning pouring in the fiber bundle width direction. This further ensures the uniformity of resin distribution in the fiber width and thickness directions, which is especially beneficial for the full impregnation of wide or thick fiber products.

[0034] In a further preferred embodiment of the present invention, a bracket 99 is fixedly connected to the outside of the sealed impregnation chamber 91, and two pipe joints 90 are fixedly connected to the top of the bracket 99. The two pipe joints 90 are rotatably connected to the inlet ends of two glue guide tubes 95 respectively. A glue delivery tube 9a is fixedly connected to the inlet end of the two pipe joints 90, and a glue supply device is externally connected to the inlet end of the glue delivery tube 9a.

[0035] In this embodiment, liquid resin is delivered from an external adhesive supply device via a delivery pipe 9a. The delivery pipe 9a diverts the resin to two pipe fittings 90. The pipe fittings 90 are rotatably connected to the inlet end of the oscillating guide pipe 95, ensuring that the guide pipe 95 remains connected and sealed to the fixed delivery pipeline during oscillation, allowing the resin to continuously and stably enter the two guide pipes 95. This pipeline connection design achieves a flexible connection between the external adhesive supply system and the internal movable injection component. The rotatable connection structure of the pipe fittings 90 is crucial; it ensures that the adhesive supply pipeline is not twisted or pulled when the guide pipe 95 performs its reciprocating oscillation function, thereby guaranteeing the continuity and sealing of the adhesive supply, preventing resin leakage, and maintaining the stability of the impregnation process.

[0036] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
