Description

Technical Field

[0001] This utility model relates to the field of quartz cloth coating technology, specifically to a coating machine. Background Technology

[0002] After the quartz cloth is woven, it is treated with a coating agent to optimize its interfacial properties with the composite material.

[0003] Coating agents, such as coupling agents, are most commonly silane coupling agents. Their molecular structure has one end (organic functional group) that can chemically bond with the resin, and the other end (siloxane functional group) that can chemically bond with the silanol groups on the surface of quartz fibers. This can significantly improve the interlaminar shear strength, resistance to damp heat aging, and electrical properties of composite materials. Coupling agents are usually dissolved in solvents (such as alcohol) or water for easy coating. After applying the coupling agent, drying is an essential and crucial step. Generally, an impregnation method is used, where the quartz cloth is continuously passed through a tank containing a coupling agent solution, allowing the cloth to be completely immersed in the solution. This method results in a large amount of coupling agent solution adhering to the cloth, leading to significant consumption. The subsequent drying and curing process requires continuous high temperatures, resulting in significant energy costs. Some methods use a pair of extrusion rollers, with the adhering coupling agent solution passing through the middle to control the amount of excess liquid removed. However, improper pressure control of the extrusion rollers can lead to uneven coating or fabric deformation. Utility Model Content

[0004] The purpose of this invention is to provide a coating machine that solves the problem of excessive coating solution on quartz cloth, making subsequent processing difficult.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A coating machine includes a frame on which an unwinding shaft, a take-up shaft, a reversing shaft, and a guide shaft are mounted. The reversing shaft is located below the area between the unwinding shaft and the guide shaft. The unwinding shaft is used to mount a roll of quartz cloth, which is wound around the reversing shaft and the guide shaft before being wound onto the take-up shaft. A spray pipe is provided on one side of the frame, parallel to the unwinding shaft. Several nozzles are evenly spaced on the spray pipe, with the nozzles facing the quartz cloth side between the unwinding shaft and the reversing shaft. A hot air blower is provided on the quartz cloth side between the guide shaft and the reversing shaft, and a heat lamp is provided below the quartz cloth between the guide shaft and the take-up shaft.

[0006] Furthermore, the heating lamp is a tubular ultraviolet heating lamp.

[0007] Furthermore, several hot air blowers are evenly spaced along a direction parallel to the unwinding shaft.

[0008] Furthermore, the unwinding shaft, the rewinding shaft, and the guide shaft are located on the upper side of the frame and are arranged on the same plane.

[0009] Furthermore, the reversing shaft is located at the bottom of the frame, and the unwinding shaft, reversing shaft, and guide shaft are arranged in a triangular pattern.

[0010] Furthermore, the lower part of the frame is provided with a liquid collection tank.

[0011] Furthermore, the nozzle is mounted on a nozzle seat, and the nozzle is tilted so that the falling coating solution flows back into the collection tank.

[0012] The beneficial effects of this utility model are: This invention employs a spray coating method, replacing the existing method of passing the quartz cloth through a solution bath. Because less coupling agent solution adheres to the quartz cloth, it is easier to dry. The cloth can be unwound while simultaneously being wound up, improving efficiency. The unwinding speed of the quartz cloth is adjustable, allowing control over the coating amount. Utilizing multiple nozzles ensures uniform coating, saving on the consumption of coupling agent solution and other coating agents, and facilitating rapid drying. Attached Figure Description

Detailed Implementation The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0015] Embodiments of this utility model: like Figures 1 to 3As shown, the coating machine includes a frame 1. The frame 1 is equipped with an unwinding shaft 2, a take-up shaft 5, a reversing shaft 3, and a guide shaft 4. The unwinding shaft 2, take-up shaft 5, and guide shaft 4 are located on the upper side of the frame 1 and are arranged on the same plane. The reversing shaft 3 is located below the area between the unwinding shaft 2 and the guide shaft 4, at the bottom of the frame 1. The unwinding shaft 2, reversing shaft 3, and guide shaft 4 are arranged in a triangular pattern. The unwinding shaft 2 is used to mount a roll of quartz cloth 9. The quartz cloth 9 passes around the reversing shaft 3 and the guide shaft 4 and then winds onto the take-up shaft 5. The take-up shaft 5 is driven by a servo motor to wind up the dried quartz cloth 9; other shafts can be non-powered.

[0016] A nozzle 6 is provided on one side of the frame 1, and the nozzle 6 is arranged parallel to the unwinding shaft 2. A plurality of nozzles 61 are evenly spaced on the nozzle 6. In this embodiment, approximately 20 nozzles 61 are installed. The nozzles 61 are inclined upwards, facing the quartz cloth 9 between the unwinding shaft 2 and the reversing shaft 3, enabling the coupling agent solution to be sprayed evenly onto the surface of the quartz cloth 9 in a mist-like manner. In other embodiments, other types of solutions can be sprayed as needed. Because the quartz cloth 9 is relatively thin, it can achieve sufficient permeability, and the consumption of coupling agent solution is small, saving costs.

[0017] A liquid collection tank 7 is provided at the lower part of the frame 1. The nozzle is mounted on a nozzle seat 62, which has a vertical baffle plate to allow excess small amounts of coating agent droplets to flow back into the liquid collection tank 7. The liquid collection tank 7 can be located below the nozzle seat 62, or an additional liquid collection tank can be located below the reversing shaft 3; in other embodiments, an integral liquid collection tank can also be located below the frame 1 to collect excess coating agent droplets.

[0018] A hot air blower 8 is provided on one side of the quartz cloth 9 between the guide shaft 4 and the reversing shaft 3. Several hot air blowers 8 are evenly spaced along a direction parallel to the unwinding shaft 2. In this embodiment, three hot air blowers are designed. The air outlet direction of the hot air blowers 8 is towards the quartz cloth 9, which plays a preliminary drying role.

[0019] A drying lamp is installed below the quartz cloth 9 between the guide shaft 4 and the winding shaft 5. The drying lamp is a tubular ultraviolet lamp 10, which is set parallel to the guide shaft 4, and the quartz cloth 9 is dried again using the ultraviolet lamp 10.

[0020] Because the amount of coupling agent solution adhering to the quartz cloth 9 is relatively small (compared to the solution tank method in the prior art), it is also relatively easier to dry. The unwinding speed of the quartz cloth 9 can be controlled between 0.8 and 1 meter / minute. After spraying the coupling agent solution, the quartz cloth 9 undergoes two drying processes to meet the requirements and can be directly wound up for use. This utility model adopts a new coating and drying method, utilizing multiple sets of nozzles 61 to meet the requirements of uniform coating, which not only saves the consumption of coupling agent solution and other coating agents, but also facilitates rapid drying.
