Detailed Implementation

[0033] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0034] like Figure 1-3As shown, the continuous production line for high flame-retardant fiberglass sheets of this utility model is provided with a raw material processing unit, a curing unit and a post-processing unit in sequence in the conveying direction of the production line; the raw material processing unit includes a fiber weaving device 1, and the curing unit includes a curing furnace 5 and a steam furnace 6. In the conveying direction, the steam furnace 6 is located downstream of the curing furnace 5.

[0035] This utility model relates to a continuous production line for high flame-retardant fiberglass sheets. By sequentially arranging a raw material processing unit, a curing unit, and a post-processing unit along the conveying direction of the production line, the raw materials can be mixed in the raw material processing unit, cured in the curing unit, and post-processed in the post-processing unit to directly obtain high flame-retardant fiberglass sheets, achieving continuous production. By setting up a fiber weaving device 1 for fiber weaving, the product width and density can be adjusted online, realizing personalized customization and flexible production functions. By setting up a steam furnace 6, the inorganic resin in the raw materials can be cross-linked and cured, ensuring the stable quality of the high flame-retardant fiberglass sheets and improving production efficiency.

[0036] Preferably, the raw material processing unit in this embodiment includes a resin platform 2 and an impregnation device 3. The impregnation device 3 is located downstream of the resin platform 2 in the conveying direction. The fiber weaving device 1 corresponds to the resin platform 2 and can be used to convey the woven fiber cloth onto the resin platform 2. After the base film 4, raw material resin can be added to it through the resin platform 2, and then the impregnation device 3 can be used for rolling and covering with a protective film to further realize continuous production. The fiber weaving device 1 is set to correspond to the resin platform 2, which can quickly add the woven fiber cloth to the raw material resin, effectively ensuring the efficiency of continuous production.

[0037] Preferably, the impregnation device 3 is equipped with a defoaming roller 11, and a pressure roller 10 is also provided upstream of the curing unit. The defoaming roller 11 can be used to roll the fiberglass mixture conveyed by the resin stage 2, and after being coated and covered with a protective film by the pressure roller 10, it enters the curing unit. The protective film can be applied by an independent automatic device, or the pressure roller 10 can be used directly to apply the film, completing the rolling and film application simultaneously; after curing, the protective film needs to be removed.

[0038] Preferably, the raw material conveyed by the resin station 2 needs to be supplemented with a setting accelerator before reaching the impregnation unit 3. The setting accelerator is evenly sprayed onto the raw material by a separate sprayer.

[0039] Preferably, it also includes a base film laying device, which includes an inflatable shaft for fixing the base film roll and a traction device 7 for pulling the base film 4. The inflatable shaft is located upstream of the resin stage 2, and the traction device 7 is located downstream of the curing unit. In this way, the base film roll can be locked on the inflatable shaft and pulled and unfolded throughout the production line by the traction device 7 to achieve the laying of the base film 4.

[0040] Preferably, the traction device 7 includes a traction shaft, on which a frequency converter is installed to control the rotation and traction of the traction shaft.

These flattening clamping rollers 12 are fixed on the fixed platform 13 and arranged on both sides of the bottom film 4. As the bottom film 4 unfolds in the length direction, the flattening clamping rollers 12 can flatten the bottom film 4 in the width direction.

[0044] Preferably, the resin platform 2 facilitates the addition of raw material resin, effectively improving production efficiency without affecting the operation of the production line. Specifically, the resin platform 2 is equipped with a raw material resin pump 21, which can quickly pump the raw material resin into the mixing tank, mix it evenly with the powder, and then spread it evenly on the bottom film 4, effectively improving production efficiency. The resin platform 2 is also equipped with a stirring device and a uniform material distribution device, which can better spread the raw material resin on the bottom film 4.

[0045] Preferred, such as Figure 3 As shown, the production line of this utility model also includes a resin mixing system 15 and an automatic metering system 14. The automatic metering system 14 is installed before the resin mixing system 15. The resin mixing system 15 includes a raw material resin outlet, which is connected to the raw material resin pump 21. The automatic metering system 14 can calculate the composition and ratio of the raw material resin and the amount of raw material resin used according to the requirements, and transmit these results to the resin mixing system 15 in the form of an electrical signal. The resin mixing system 15 can mix and stir the components according to the above results of the automatic metering system 14, and discharge the mixture according to the required amount, and send the mixture to the bottom film 4.

[0047] Preferably, the temperature inside the steam furnace 6 of this invention is 120°C. When the cured board enters the steam furnace 6, the inorganic resin can further react with the active filler and cure in the steam environment, preventing the inorganic resin from hydrolyzing due to incomplete curing. The cured inorganic resin has good water resistance, thereby improving the quality of the board.

[0048] Preferably, the post-processing unit of this invention includes a winding system and a cutting system arranged sequentially in the transmission direction.

[0049] In a further preferred embodiment, the cutting system includes a cutting edge device 8 and a cross-cutting device 9 arranged sequentially in the transmission direction, so that the cured board can be directly cut to obtain the finished high flame retardant fiberglass board.

[0050] Furthermore, the cutting system of this invention is also connected to the packaging unit, enabling the finished high flame-retardant glass sheets to be packaged directly, thereby further realizing the continuous production of high flame-retardant fiberglass sheets.

[0051] This utility model relates to a high flame-retardant fiberglass sheet production equipment, which includes a continuous production line as described above, and an electrical control unit. The control unit is electrically connected to the raw material processing unit, the base film laying device, the curing unit, and the post-processing unit.

It allows for real-time control as needed during production and facilitates maintenance and repair of each unit on the production line.

[0052] The specific working process of the production line and equipment of this utility model is as follows:

Under the action of the traction shaft controlled by the frequency converter, the decorative printing base film is laid at a speed of 0.5 to 10 meters per minute. During the laying process, the tension applied by the flattening clamping roller 12 keeps it flat.

[0054] Through the calculation of the metering system, the raw material resin is mixed in the resin mixing system 15 according to a certain ratio. After being fully stirred, it is pumped onto the unfolded decorative printing base film on the resin table 2 by the raw material resin pump 21 and evenly laid by the thickness gauge.

[0055] Meanwhile, the fiber weaving device 1 weaves the fiber yarn into a two-dimensional fiberglass cloth according to the designed pattern. After the raw material resin is laid on the decorative printing base film, the fiber weaving device 1 lays the woven two-dimensional fiberglass cloth on the raw material resin.

[0056] Before the above-mentioned mixed material is conveyed to the impregnation device 3, the spraying machine sprays the accelerator evenly onto the mixed material.

[0057] After the mixed materials pass through the impregnation device 3 and are bonded under the pressure of the defoaming roller 11, they are covered with a protective film by the pressure roller 10 and then enter the curing oven 5. The temperature of the curing oven 5 is gradually increased from 40 degrees to 80 degrees to promote resin curing and shaping; then it enters the steam oven 6 to further ensure the curing effect.

[0058] In this embodiment, the winding device is located between the steam furnace 6 and the traction shaft. After the board has been cured, it leaves the steam furnace 6, is first wound up by the winding device to remove the protective film, and then cut into boards of a fixed length by the cutting device.
