Description

Technical Field

[0001] This invention relates to the field of material coating preparation technology, specifically to a material coating preparation device and method for white-based, fully opaque, anti-wicking PVC edge-covering fabric. Background Technology

[0002] In tent and awning manufacturing, PVC clips are needed as accessories for connecting and fixing to aluminum alloy poles. The edge-binding fabric is internationally known as Keder. The clip material has a structure where one side is a polyester fiber mesh without PVC, and the other side is coated with PVC. In actual use, the polyester fiber mesh layer faces outwards, directly contacting rain and snow in outdoor environments. Ordinary polyester fiber mesh does not have anti-wicking properties, allowing rainwater and snow to penetrate the material along the polyester fiber mesh, leading to dirt, mold, and reduced strength, affecting appearance and lifespan. Therefore, a white, fully blackout, anti-wicking PVC edge-binding fabric material was developed. Summary of the Invention

[0009] As a preferred embodiment of the present invention, the scrapers on both sides are inclined toward the side away from the movable shell, and the sidewall of the scraper away from the movable shell is arc-shaped.

[0010] As a preferred embodiment of the present invention, the movable plate has a concave cross-section and vertical grooves on both the front and rear sides. Slide plates are movably connected in each of the vertical grooves, and the slide plates are fixedly connected to the movable shell.

[0011] A method for using a coating preparation device for white-based, fully opaque, anti-wicking PVC edge-sealing fabric includes the following steps: S1: Preparation of raw materials, including white base coat PVC paste: 100 parts E-PVC resin powder, 55-70 parts plasticizer, 2-5 parts ESO (soybean oil), 2-5 parts barium zinc stabilizer, 20-50 parts filler, 1-3 parts mildew inhibitor, 6-12 parts titanium dioxide; intermediate layer black PVC: 100 parts E-PVC resin powder, 55-70 parts plasticizer, 2-5 parts ESO (soybean oil), 2-5 parts barium zinc stabilizer. The PVC paste consists of: 20-50 parts stabilizer, 15-20 parts filler, 5-10 parts titanium dioxide, and 5-10 parts carbon black; 100 parts E-PVC resin powder, 55-70 parts plasticizer, 2-5 parts ESO (soybean oil), 2-5 parts barium zinc stabilizer, 20-50 parts filler, 1-3 parts mildew inhibitor, 1-2 parts UV inhibitor, 0.5-1.5 parts antioxidant, and 30 parts titanium dioxide. Various color pastes can be added to adjust the color to various shades. S2: The prepared white base PVC paste, intermediate black PVC paste, and top PVC paste are sequentially added into the inner cavity of the movable shell from right to left through the feed pipe. The device is then connected to an external power supply and control system. The second motor is started, which drives the second shaft to rotate. The second shaft drives the gear to rotate, and through gear transmission, all the second shafts rotate together. This allows the stirring rods on the second shafts to perform stirring operations on the inner cavity of the movable shell, ensuring the stability of the raw materials. S3: After soaking in ink for 24 hours, the waterproof polyester fiber mesh is placed on the designated board, and the board with the waterproof polyester fiber mesh is transported to the inner cavity of the fixed frame. The first motor is started, the first motor drives the first rotating shaft to rotate, the first rotating shaft drives the conveyor roller to rotate, the conveyor roller drives the conveyor belt to rotate, and the conveyor belt is used to transport the board with the waterproof polyester fiber mesh to the designated position on the fixed frame. S4: Reset the movable shell to the left position. Depending on the thickness of the material to be applied, the electric push rod on the left side of the movable shell needs to be activated. The electric push rod pushes the movable plate to move, and the movable plate drives the scraper to move, so that the scraper moves to a position with a specified height difference from the conveyor belt. S5: Start the top drive motor. The drive motor drives the threaded rod to rotate. The threaded rod engages with the connecting plate and moves, causing the rightmost movable shell to move to the right. When the movable shell moves to the upper position of the waterproof polyester fiber mesh, the nozzle is started at the same time. The nozzle is used to spray the raw material inside the movable shell onto the waterproof polyester fiber mesh, completing the white base PVC paste coating process. S6: Then, at specified intervals, the drive motors are started sequentially to complete the coating of black opaque PVC paste on the white base PVC paste coating, and the coating of the outer PVC paste of the edge binding fabric on the black opaque PVC paste coating. The coated material is then transported to the oven, and the oven temperature is controlled between 195-205℃ and the speed is 12-18m / min to fully plasticize the product and realize the production of white base opaque anti-wicking PVC edge binding fabric material. S7: During the coating process, the movable shell drives the scraper to move. The scraper smooths the coating material and controls the thickness, improving the production quality. It also starts the negative pressure equipment. Excess coating material enters the inner cavity of the scraper through the through hole under the negative pressure. The material in the inner cavity of the scraper is recovered into the movable shell through the connecting pipe, reducing material waste and improving the performance.

[0012] This invention provides a device and method for preparing a coating of white-based, fully opaque, anti-wicking PVC edge-covering fabric, which has the following beneficial effects: 1. This invention innovates the formulations of white base PVC paste, black light-blocking PVC paste with black layer, and edge-binding PVC paste. Furthermore, the polyester fiber mesh uses the highest grade anti-wicking mesh, which can effectively improve the full light-blocking effect and anti-wicking effect, and also increase the adhesion effect, effectively solving the problem of low peel strength between the anti-wicking mesh and the PVC paste. 2. This invention comprises a displacement drive component, a leveling and recycling component, movable shells, and nozzles. The three movable shells respectively hold three raw materials: white base PVC paste, black opaque PVC paste with a black layer, and PVC paste for the edge binding fabric. Driven by a drive motor, the three movable shells sequentially apply the coating to the waterproof polyester fiber mesh fabric through the nozzles. This effectively improves the preparation efficiency of the edge binding fabric coating. Furthermore, the scraper controls the leveling and thickness of the coating, effectively improving the quality of the edge binding fabric coating. Excess coating material can be recycled using a negative pressure device, reducing material waste and resulting in excellent performance. Attached Figure Description

Through the gear (19) transmission, all the second rotating shafts (17) rotate together, so that the stirring rod (18) on the second rotating shaft (17) stirs the inner cavity of the movable shell (2) to ensure the stability of the raw material properties. S3: After soaking in ink for 24 hours, the waterproof polyester fiber mesh is placed on the designated board and the board with the waterproof polyester fiber mesh is transported to the inner cavity of the fixed frame (1). The first motor (12) is started, the first motor (12) drives the first rotating shaft (11) to rotate, the first rotating shaft (11) drives the conveyor roller (9) to rotate, the conveyor roller (9) drives the conveyor belt (10) to rotate, and the conveyor belt (10) is used to transport the board with the waterproof polyester fiber mesh to the designated position on the fixed frame (1). S4: Reset the movable shell (2) to the left position. The electric push rod (23) on the left side of the movable shell (2) needs to be activated according to the thickness of the raw material to be applied. The electric push rod (23) pushes the movable plate (22) to move. The movable plate (22) drives the scraper (24) to move, so that the scraper (24) moves to a position with a specified height difference from the conveyor belt (10). S5: Start the top drive motor (15), drive motor (15) drives threaded rod (14) to rotate, threaded rod (14) engages with connecting plate (16) to move, so that the rightmost movable shell (2) moves to the right. When the movable shell (2) moves to the upper position of the waterproof yarn polyester fiber mesh, the nozzle (4) is started at the same time. The nozzle (4) sprays the raw material in the inner cavity of the movable shell (2) onto the waterproof yarn polyester fiber mesh to complete the white base PVC paste coating process. S6: Then, at specified intervals, start the drive motor (15) sequentially to complete the coating of black opaque PVC paste on white base PVC paste coating, the coating of PVC paste on the edge binding fabric on black opaque PVC paste coating, and transport the coated material to the oven, control the oven temperature between 195-205℃ and the speed between 12-18m / min, so that the product is completely plasticized, and realize the production of white base opaque anti-core absorption PVC edge binding fabric material; S7: During the coating process, the movable shell (2) drives the scraper (24) to move. The scraper (24) scrapes the coating material and controls the thickness, improving the production quality. It also starts the negative pressure equipment (26). Excess coating material enters the inner cavity of the scraper (24) through the through hole (27) under the action of negative pressure. The material in the inner cavity of the scraper (24) is recovered into the movable shell (2) through the connecting pipe (25), reducing the waste of material and improving the performance.
