Description

Technical Field

[0001] This invention relates to an automatic processing equipment and process for carbon fiber woven fabrics, belonging to the field of carbon fiber woven fabric post-processing technology. Background Technology

[0002] Carbon fiber is primarily composed of carbon elements and possesses properties such as high temperature resistance, friction resistance, electrical conductivity, thermal conductivity, and corrosion resistance. It has a fibrous, flexible appearance and can be processed into various fabrics. Due to its low density, carbon fiber has high specific strength and specific modulus. The main application of carbon fiber is as a reinforcing material in composites with resins, metals, ceramics, and carbon, creating advanced composite materials. Carbon fiber woven fabrics are made by weaving continuous carbon fibers or short carbon fiber yarns. Based on the weaving method, carbon fiber fabrics can be divided into woven fabrics, knitted fabrics, and non-woven fabrics. Applications of carbon fiber woven fabrics include aircraft and aerospace equipment, sporting goods, and industrial equipment parts.

[0003] Current carbon fiber woven composite material manufacturing equipment suffers from numerous problems, including a lack of systematic control, poor quality stability, and inability to mass-produce. A key contributing factor is that continuous carbon fiber weaving modules produce woven fabrics prone to carbon fiber breakage, missed needles, and slippage, leading to large mesh sizes, structural defects, and an inability to guarantee continuity. Furthermore, traditional separate operations in the impregnation, spreading, and curing modules present a series of issues, including difficulties in spreading, unstable spreading dimensions, large required steel frame weight, inconvenient operation, adhesive adhesion to contact parts, and difficulty in cleaning. Summary of the Invention

[0004] To address the aforementioned issues, this invention provides an automated processing equipment and process for carbon fiber woven fabrics, which enables automated, intelligent, and unmanned preparation and control of carbon fiber woven fabric processing, significantly improving the production efficiency and quality of carbon fiber woven fabrics while reducing labor costs.

Below the roller is a small impregnation tank capable of fully accommodating the carbon fiber woven fabric, used for impregnating the carbon fiber woven fabric. The small impregnation tank is connected to an impregnation tank lifting device, which drives the small impregnation tank to move up and down. Each layer of the impregnation tank is also equipped with a pressure plate. The pressure plates within the five layers are interconnected and connected to the pressure plate lifting device. The pressure plates are located above the carbon fiber woven fabric and abut against it. The pressure plate lifting device drives the pressure plates to move up and down. A second exhaust device is also provided above the impregnation tank to exhaust waste gas during the impregnation process. A heating device is located on the side of the impregnation tank and is used to control the impregnation temperature.

[0008] In one embodiment of the present invention, the drying device is a drying box, and the widening device is a widening machine.

[0009] In one embodiment of the present invention, a solvent removal device is provided on the side of the widening device away from the impregnation device. The solvent removal device includes a circulating fan, a third exhaust device, and a stainless steel bracket. The stainless steel bracket is used to place the carbon fiber woven fabric, and the circulating fan is installed inside the solvent removal device.

The oven is located on one side of the adhesive spraying machine, and the conveyor belt passes through the adhesive spraying machine and the oven. The cutting knife is located above the conveyor belt on the side of the oven away from the adhesive spraying machine. The adhesive spraying machine is provided with an adhesive spraying nozzle and an adhesive spraying exhaust device, and the adhesive spraying nozzle is located above the conveyor belt.

[0012] In one embodiment of the present invention, the reverse adhesive spraying device includes an adhesive spraying machine, an oven, and a conveyor belt.

The gripping device is located above the conveyor belt of the reverse side adhesive spraying device and is used to grip the carbon fiber woven fabric on the conveyor belt and place it on the cutting machine for cutting the carbon fiber woven fabric. A storage device is provided on one side of the cutting device.

[0014] A second objective of this invention is to provide an automated processing technology for carbon fiber woven fabrics. The method utilizes the aforementioned automated processing equipment for carbon fiber woven fabrics and includes the following steps:

[0015] Step 1: The unwinding device places the carbon fiber woven fabric onto the conveyor belt at a uniform speed. Driven by the conveyor belt, it enters the soaking tank containing acetone solution. After soaking for 30 minutes, the excess acetone in the carbon fiber woven fabric is sucked out by the acetone absorption device inside the material and then enters the drying device. After drying for 120 minutes, it enters the winding device under the action of the conveyor belt to form a roll.

[0016] Step 2: Place the carbon fiber woven fabric to be impregnated on the impregnation buffer device. The carbon fiber woven fabric is driven into the impregnation tank by the rollers in the impregnation buffer device. The pressure plate lifting device controls the up and down movement of the carbon fiber woven fabric in the impregnation tank to achieve full and uniform impregnation. The impregnation tank lifting device drives the small impregnation tank to rise and fall to meet the different requirements of immersion and draining of the carbon fiber woven fabric. The impregnation time is 60 minutes, and the draining time is 60 minutes. During the impregnation process, the second exhaust device ensures the discharge of waste gas, and the heating device on the side of the impregnation tank controls the impregnation temperature.

[0017] Step 3: After the carbon fiber woven fabric comes out of the impregnation device, it directly enters the spreading device; the spreading time is 30 minutes, and the spreading size is 3100mm*1200mm.

[0018] Step 4: After the carbon fiber woven fabric comes out of the expansion device, it enters the solvent removal device, is placed on a stainless steel support, and is solvent removed for 120 minutes under the blowing of a circulating fan.

[0019] Step 5: After the carbon fiber woven fabric has been dissolved, it is placed in the curing device and placed on a stainless steel support for 120 minutes of curing. After curing, the carbon fiber woven fabric is moved to the cooling support for 120 minutes of cooling.

[0020] Step 6: After impregnation, expansion and curing, the carbon fiber woven fabric enters the front and back adhesive spraying process. First, the front is sprayed with adhesive. Under the action of the adhesive spray nozzle, the carbon fiber woven fabric is evenly sprayed with adhesive. The speed of the adhesive spray nozzle is 0.3m / s. After spraying, it is conveyed into the drying oven by the conveyor belt. After drying, it is preliminarily cut with a cutting knife to facilitate the back adhesive spraying.

[0021] Step 7: Turn the carbon fiber woven fabric over and put it into the conveyor belt of the reverse side glue spraying device. The reverse side glue is sprayed under the drive of the conveyor belt of the reverse side glue spraying device.

[0022] Step 8: After the reverse side adhesive is applied, the gripping device picks up the carbon fiber woven fabric from the conveyor belt of the reverse side adhesive application device and places it on the platform of the cutting machine. The cutting machine cuts the carbon fiber woven fabric using upper and lower roller cutters. After the cutting is completed, the entire processing of the carbon fiber woven fabric is finished.

[0023] Step 9: The processed carbon fiber woven fabric will be stored in a storage device. The temperature of the carbon fiber storage device is 20℃±10℃, and the absolute moisture content of each kg of dry air is no more than 13g of water. At least 5 collection boxes will be used to store carbon fiber woven fabric with a width of 1000mm to 1200mm.

[0024] Beneficial effects

[0025] (1) The present invention combines different processing units of carbon fiber woven fabrics through reasonable design, thereby improving the processing efficiency and quality of carbon fiber woven fabrics. Compared with other woven fabric processing equipment, the present invention realizes automated, intelligent and unmanned preparation and control of carbon fiber woven fabric processing, which greatly improves the production efficiency and quality of carbon fiber woven fabrics and reduces labor costs.

[0026] (2) The cleaning device set up in this invention uses acetone solution for cleaning, combines the conveyor belt with the soaking tank, and presses the conveyor belt into the soaking tank by the pressure roller, which ensures that the carbon fiber woven fabric can be fully soaked in the soaking tank while moving forward. Compared with the traditional method, which still requires manual placement and removal of carbon fiber woven fabric, this greatly saves labor costs and improves automation.

[0027] (3) This invention redesigns and upgrades the traditional impregnation, spreading, and curing modules. Traditional separate operations suffer from a series of problems, including difficulty in spreading, unstable spreading dimensions, large required steel frame weight, inconvenient operation, adhesive residue on contact parts, and difficulty in cleaning. To address these issues, this invention, in addition to cleaning and drying, first impregnates the fabric. During impregnation, a pressure plate controls the full impregnation of the carbon fiber woven fabric, ensuring consistent impregnation absorption and fabric thickness deformation. Subsequently, drying is completed using a solvent removal device. After impregnation and solvent removal, the spreading stage begins. Simultaneously, utilizing the principle of a textile width-setting machine, the fabric edges are automatically clamped and spread, continuously transferred to ensure stable spreading.

[0028] (4) The front and back adhesive spraying device of this invention replaces the original manual adhesive spraying. After the front adhesive is sprayed, the carbon fiber woven fabric can be flipped to the other side by a flipping platform, and then the double-sided adhesive spraying is completed. Compared with traditional manual adhesive spraying, the front and back adhesive spraying device of this invention improves the adhesive spraying quality, stabilizes the adhesive spraying quality, reduces labor costs, and allows for uninterrupted operation.

[0029] (5) The present invention provides a cutting device that can automatically and accurately cut composite materials, replacing the original manual cutting. After the carbon fiber woven fabric is placed on the operating table of the cutting machine and fixed in a fixed position by the gripping device, the cutting machine cuts the carbon fiber woven fabric according to the set size. No manual cutting is required, avoiding the injury to the human body caused by debris during cutting. Moreover, the cut surface of the product is flatter and more beautiful than that of manual cutting. Attached Figure Description

[0040] Furthermore, the washing and drying devices 7 are also equipped with a conveyor belt 2. The unwinding machine 1 and the winding machine 8 are located at both ends of the conveyor belt 2. The washing device includes an soaking tank 4. The conveyor belt 2 is arranged on the soaking tank 4. The conveyor belt 2 is used to transport the carbon fiber woven fabric from the unwinding machine 1 through the soaking tank 4 and the drying device 7 to the winding machine 8.

[0041] Optionally, the soaking tank 4 is filled with acetone solution, and the cleaning device further includes an anti-evaporation hood 3, a first exhaust device 5, and an acetone absorption device 6 for the material. The anti-evaporation hood 3 is placed over the soaking tank 4 to prevent acetone evaporation. The first exhaust device 5 is placed on the anti-evaporation hood 3 to discharge waste gas. The acetone absorption device 6 for the material is placed inside the cleaning device and abuts against the conveyor belt 2 inside the cleaning device. The acetone absorption device 6 for the material uses gauze as raw material to absorb the acetone on the carbon fiber woven fabric after soaking. It needs to be replaced after a certain period of time. After soaking, the carbon fiber woven fabric continues to move forward with the conveyor belt 2, and the excess acetone on the carbon fiber woven fabric is removed under the action of the acetone absorption device 6 for the material.

[0042] Optionally, the carbon fiber woven structure is a knitted weft-knitted structure, woven using a Cixing carbon fiber braiding machine, with dimensions of 2800mm*960*8mm and a weight of 3.2Kg±0.2Kg. After continuous weaving, the carbon fiber woven fabric will be formed into a roll and fed into the cleaning and drying device 7 via the unwinding machine 1.

[0043] Optionally, the conveyor belt 2 is also connected to multiple pressure rollers. Under the action of the pressure rollers, the conveyor belt 2 moves the carbon fiber woven fabric forward along the bottom of the soaking tank 4. The preferred operating speed of the conveyor belt 2 is 92 mm / min. During this process, the fabric will be continuously soaked in the soaking tank 4, ensuring that the fabric is soaked for 30 minutes without stopping the equipment, achieving sufficient soaking.

[0044] Optionally, the drying device 7 is a drying chamber. The carbon fiber woven fabric enters the drying chamber via the conveyor belt 2 for drying. The drying chamber is located at the rear end of the soaking tank 4, and the drying time is 12 minutes. Experiments have shown that the fabric can be naturally dried in 12 minutes at room temperature, ensuring thorough drying of the carbon fiber woven fabric. The maximum drying temperature is 100℃, and the adjustable range is from room temperature to 100℃. The temperature detection accuracy of the drying chamber is ±0.1℃, the heating rate of the drying chamber is 2~3℃ / min, and the temperature uniformity is ±5℃. During the washing and drying process, the equipment operates continuously, and the time required for a single 3000mm piece of fabric is within 45 minutes.

[0045] Furthermore, the impregnation device includes an impregnation buffer device 9, an impregnation tank 10, a second exhaust device 11, a pressure plate lifting device 12, an impregnation tank lifting device 13, and a heating device 14. The impregnation buffer device 9 includes a support and five parallel layers of rollers fixed on the support. The rollers are used to place the carbon fiber woven fabric and drive it into the impregnation tank 10. The impregnation tank 10 is divided into five layers in the vertical direction corresponding to the rollers of the impregnation buffer device 9. Each layer has a material inlet gate and a material outlet gate on both sides for the entry and exit of the carbon fiber woven fabric. Each layer of the impregnation tank 10 also has a heating device. The same roller as the impregnation buffer device 9 is used to support and move the carbon fiber woven fabric. A small impregnation tank capable of fully accommodating the carbon fiber woven fabric is provided below the roller in the impregnation tank 10 for impregnating the carbon fiber woven fabric. The small impregnation tank is connected to the impregnation tank lifting device 13, which is used to drive the small impregnation tank to move up and down. Each layer of the impregnation tank 10 is also provided with a pressure plate. The pressure plates in the five layers are interconnected and connected to the pressure plate lifting device 12. The pressure plate is located above the carbon fiber woven fabric and abuts against the carbon fiber woven fabric. The pressure plate lifting device 12 is used to drive the pressure plate to move up and down. When the impregnation tank lifting device 13 raises the small impregnation tank, the carbon fiber woven fabric will begin to be impregnated. By controlling the raising and lowering of the small impregnation tank, different requirements for soaking and draining of the carbon fiber woven fabric can be met. Since the carbon fiber woven fabric will generate buoyancy in the impregnation tank and cannot be fully impregnated, a pressure plate is set to fully submerge it. At the same time, the pressure plate is connected to the pressure plate lifting device 12. By controlling the raising and lowering of the pressure plate, the carbon fiber woven fabric is impregnated more fully and evenly. A second exhaust device 11 is also set above the impregnation tank 10, which is connected to the inside of the impregnation device through a pipe. The second exhaust device 11 is used to exhaust the waste gas during the impregnation process. The heating device 14 is located on the side of the impregnation tank 10.

A cooling support 19 is provided on one side of the curing chamber. The curing time of the curing device is 120 minutes. After curing, the carbon fiber woven fabric is moved to the stainless steel cooling support 19 for cooling.

[0049] Optionally, the front-side adhesive spraying device includes an adhesive sprayer, an oven 22, a cutting blade 23, and a conveyor belt 24. The oven 22 is located on one side of the adhesive sprayer, and the conveyor belt 24 passes through the adhesive sprayer and the oven 22. The cutting blade 23 is located above the conveyor belt 24 on the side of the oven 22 away from the adhesive sprayer. The adhesive sprayer is equipped with an adhesive spray nozzle 20 and an adhesive exhaust device 21. The adhesive spray nozzle 20 is located above the conveyor belt 24, and the adhesive exhaust device 21 is used to exhaust waste gas during the front-side adhesive spraying process.

After soaking for 30 minutes, the excess acetone in the carbon fiber woven fabric is sucked out by the acetone suction device 6 and then enters the drying device 7. After drying for 120 minutes, it enters the winding device 8 under the action of the conveyor belt 2 to form a roll.

[0058] Step 2: Place the carbon fiber woven fabric to be impregnated on the impregnation buffer device 9. The carbon fiber woven fabric is driven into the impregnation tank by the roller in the impregnation buffer device. The pressure plate lifting device 12 controls the up and down movement of the carbon fiber woven fabric in the small impregnation tank to achieve full and uniform impregnation. The impregnation tank lifting device 13 drives the small impregnation tank to rise and fall to meet the different requirements of immersion and draining of the carbon fiber woven fabric. The impregnation is 60 minutes and the draining is 60 minutes. During the impregnation process, the second exhaust device 11 ensures the discharge of waste gas.

[0059] Step 3: After the carbon fiber woven fabric comes out of the impregnation device, it directly enters the spreading device 15; the spreading time is 30 minutes and the spreading size is 3100mm*1200mm.

[0060] Step 4: After the carbon fiber woven fabric comes out of the expansion device 15, it enters the solvent removal device, is placed on the stainless steel bracket 18, and is solvent removed for 120 minutes under the blowing of the circulating fan 16.

[0061] Step 5: After the carbon fiber woven fabric has been dissolved, it is placed in the curing device and placed on the stainless steel support 18 for 120 minutes of curing. After curing, the carbon fiber woven fabric is moved to the cooling support 19 for 120 minutes of cooling.

[0062] Step 6: After impregnation, expansion and curing, the carbon fiber woven fabric enters the front and back adhesive spraying process. First, the front is sprayed with adhesive. Under the action of the adhesive spray nozzle 20, the carbon fiber woven fabric is evenly sprayed with adhesive. The speed of the adhesive spray nozzle 20 is 0.3m / s. After spraying, it is conveyed into the drying oven 22 by the conveyor belt 24. After drying, it is preliminarily cut with the cutting knife 23 to facilitate the back adhesive spraying.

[0063] Step 7: Turn the carbon fiber woven fabric over and put it into the conveyor belt 24 of the reverse side glue spraying device. The reverse side glue is sprayed under the drive of the conveyor belt 24 of the reverse side glue spraying device.

[0064] Step 8: After the reverse side is sprayed with adhesive, the gripping device 25 grips the carbon fiber woven fabric on the conveyor belt 24 of the reverse side spraying device and places it on the platform of the cutting machine 26. The cutting machine 26 cuts the carbon fiber woven fabric using upper and lower roller cutters. After the cutting is completed, the processing of the carbon fiber woven fabric is finished.

[0065] Step 9: The processed carbon fiber woven fabric will be stored in a storage device. The temperature of the carbon fiber storage device is 20℃±10℃, and the absolute moisture content of each kg of dry air is no more than 13g of water. At least 5 collection boxes can be stored. Carbon fiber woven fabrics with a width of 1000mm~1200mm can enter the collection boxes. The function of the storage device is to prevent dust and pollution.

[0066] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention.
