Description

Technical Field

[0001] This utility model relates to the field of glass fiber reinforcement production technology, specifically, a fiber-reinforced composite material photocuring molding production line. Background Technology

[0002] Resin curing technology is a crucial step in the molding of polymer materials, with photocuring and thermocuring being the two main processes, playing a vital role in industrial production. Photocuring technology originated in the 1960s, utilizing ultraviolet (UV) or visible light to initiate free radical or cationic polymerization reactions in photosensitive resins, achieving cross-linking and curing of the polymer chains. Its core advantages lie in rapid molding (second-level curing), low-temperature operation (avoiding heat damage), and precise control (selective curing through illuminated areas). However, photocuring relies on the penetrating power of light; the penetration depth of UV or visible light into resin is limited, typically only suitable for thin layers or small parts. For thick-walled or complex structures, the surface layer may be fully cured while the interior remains uncured. Thermocuring, as a traditional process, activates curing initiators (such as amines and acid anhydride peroxides) in the resin system with heat, promoting thermal cross-linking reactions in epoxy resins, unsaturated polyurethane polyesters, etc. This technology features a wide range of material systems (adaptable to high-temperature stable components) and thorough deep curing, maintaining its irreplaceable position in high-performance fields such as aerospace composites and automotive structural adhesives. However, its high energy consumption (curing temperature often reaches 120-200℃), long cycle (several hours) and thermal stress problems have prompted the industry to improve towards low temperature and high efficiency.

[0003] Traditional fiber composite material production processes have high requirements for molds and drying ovens, resulting in excessively high production costs and low efficiency for producing large-diameter materials. Utility Model Content

[0004] To address the aforementioned issues, this utility model provides a fiber-reinforced composite material photocuring molding production line, comprising multiple yarn racks, guide plates, resin tanks, pressure bars, molding dies, photocuring equipment, counters, traction machines, cutting machines, and automatic packaging machines. The photocuring equipment is divided into a main photocuring section and a pre-photocuring section. The main photocuring section adopts a 360° annular photocuring setup. The main photocuring section has an overall box-shaped structure, including a box body. The upper part of the box body has an openable main photocuring section. The middle of the main photocuring section has two opposing semi-circular structures. The inner walls of the semi-circular structures are equipped with photocuring irradiation heads. The two opposing semi-circular structures form a channel as the main photocuring channel.

[0005] In the above technical solution, the fibers wound by multiple yarn frames pass through the guide plate and pressure bar and are placed at the bottom of the resin tank. The fibers pass through the forming die head and are twisted into a molded product and enter the photocuring equipment. After passing through the counter, they enter the interior of the traction machine and are then fed into the cutting machine operating platform and then into the automatic packaging machine.

[0006] The specific production steps are as follows:

[0007] Step 1: Place the fibers on the yarn rack, arranging them according to a set pattern;

[0008] Step 2: Calculate the required number of fibers based on the forming die and pass them through the guide plate;

[0009] Step 3: Pass the fiber through the pressure bar, and the fiber passes through the bottom of the resin tank through the action of the pressure bar;

[0010] Step 4: Pour the prepared resin into the resin tank;

[0011] Step 5: The impregnated fibers are molded into the desired shape using a molding die to form the initial molded product;

[0012] Step Six: After the surface resin of the molded product is dried in the pre-curing section, it enters the main curing section for light irradiation to accelerate the curing and molding process.

[0013] Step 7: The cured product passes through a counter, which sends a prompt message back to the light-shielding platform. The light-shielding plate is for irregularly shaped ribs, while straight ribs are opened as needed.

[0014] Step 8: Under the action of the traction machine, the material is cut to the required length by the cutting machine;

[0015] Step 9: Pack the products with the cut numbers using an automatic packaging machine;

[0016] Step 10: Transport the packaged products to a spacious area or construction site.

[0017] A further improvement to this invention is that the photocuring equipment is further enclosed in a housing, with the equipment itself housed within this housing. The top of the housing has an exhaust vent and an indicator light that illuminates during operation. Enclosing the photocuring equipment in a relatively sealed housing prevents the waste gas generated during production from being directly released into the production workshop, protecting the health of the operators. The exhaust vent on the housing can be connected to a pipeline to transmit the waste gas to a waste gas treatment device for processing. The indicator light serves as a warning.

[0018] In this invention, the main light curing section adopts a 360° annular light curing device; the pre-curing section includes a pre-curing tank, which is set on one side of the main light curing channel, and a light curing irradiation head is set facing the profile to be cured. The pre-curing tank allows the resin on the glass fiber surface to be pre-cured, so that the resin will not drip when entering the formal light curing process, thus protecting the light source of the light curing section; the main light curing section is set in three sections, and each section is equipped with 16 LED light sources; the upper half of the main light curing section is equipped with a handle for easy opening and closing, and the lower half is equipped with a base at the grounding point; the light curing device also includes a cooling system, which adopts a water circulation cooling device.

[0019] In the above improvements, the main curing section and the pre-curing section use LED light sources, and the protective glass for the LED light sources uses quartz lenses, with a standard optical power of 12000-18000 mw / cm². 2 The power adjustment is digitally adjustable, with a wavelength range of 365nm-395nm. The energy fluctuation is less than 10% after multiple lighting cycles and less than 10% in different regions.

[0020] The beneficial effects of this utility model are: the photocuring part of this utility model uses 360° irradiation to process and produce large-diameter glass fiber reinforcement materials, and the three-stage curing method accelerates curing, shortens curing time, and improves efficiency.

The photocuring equipment 7 is divided into a main photocuring section and a pre-photocuring section. The main photocuring section adopts a 360° annular photocuring setting. The main photocuring section has a box-shaped structure, including a box body 701. The upper part of the box body 701 has an openable photocuring section. The middle of the main photocuring section has two opposing semi-circular structures. The inner wall of the semi-circular structures is provided with a photocuring irradiation head 703. The two opposing semi-circular structures form a channel as the main photocuring channel 702.

[0029] The pre-curing section includes a pre-curing tank 706, which is located on one side of the main curing channel 702. A curing head is provided facing the profile to be cured. The curing section is set in three sections, with 16 LED light sources in each section. The upper part of the housing 701 of the curing equipment 7 is provided with a handle 704 for easy opening and closing, and the lower part is provided with a base 705 at the grounding point.

[0030] The UV curing device 7 is also provided with a housing 12, which encapsulates the UV curing device 7. The top of the housing 12 is provided with an exhaust vent 1201 for exhausting air and an indicator light 1202 that illuminates during operation.

[0031] like Figure 5 As shown, in this embodiment, the photocuring device 7 also includes a cooling system, which employs a water-circulating cooling system. The photocuring device 7 also includes a power supply, an electronic control system, a water-cooling system, and an irradiation head. Each light source is equipped with 16 LEDs; the protective glass for the LED light sources uses quartz lenses, and the standard optical power is 12000-18000 mw / cm². 2 The power adjustment is digitally adjustable, with a wavelength between 365nm and 395nm. The energy fluctuation is less than 10% after multiple lighting cycles and less than 10% in different areas. The water cooling system uses a water circulation cooling device to provide internal circulating water with a cooling effect for the LED lights, ensuring heat dissipation. The compressor has a cooling capacity of 15P, and one water chiller can power 3 lights and pre-cured lights, with a power consumption of 12KW. The total power of the equipment is approximately 50KW.

[0032] In this embodiment, a light-shielding plate 6 may also be included. The light-shielding plate 6 is disposed between the molding die head 5 and the photocuring device 7. The molded product can be completely covered by the light-shielding plate 6 as needed to prevent the product from being irradiated by the light source when it enters the photocuring device 7, thus ensuring that the covered part remains uncured. Removing the light-shielding plate 6 can also allow the uncured part of the product to be placed on the required mold for bending, and then irradiated by the light source to bend the product and allow it to cure quickly to obtain the desired product.

[0033] In this embodiment, the equipment control functions include: individual LEDs can be turned on / off independently or switched on / off according to material progress; LED power can be adjusted; the lights turn off when the cooling equipment malfunctions and alarms; the entire machine uses an exhaust fan for heat dissipation to remove excess heat from the machine; only the light curing method allows for barrel-shaped irradiation; in addition, it also includes leakage protection, overload protection, short circuit protection, and over-temperature protection.
