TECHNICAL FIELD
[0001] The utility model relates to a kind of automatic film applicator with wire bar fixing device, specifically refers to a kind of by push plate, wire bar fixing piece and weight adding weight composition, the weight of weight adding weight can be selected to adjust coating pressure, and the automatic film applicator with wire bar fixing device that wire bar is conveniently fixed. BACKGROUND
[0002] Wire bar coating technology is a kind of slit coating film forming technology. Wire bar coating is to wind stainless steel wire with different diameters on a stainless steel rod with certain diameter and length to obtain wire bar with winding wire, and to prepare coating film with different thickness by the gap between steel wires. By selecting appropriate wire diameter and winding method, the thickness of coating can be accurately controlled. In addition to winding wire bar, there is also extruded wire bar, which is to extrude different size continuous grooves on a smooth steel rod by cold extrusion process, and to control the thickness of coating wet film by the size of groove, and the film forming principle is similar to winding wire bar.
[0003] Wire bar coating technology has been widely used in many fields due to its simple operation, uniform coating and wide application range. In adhesive, ink or paint, plastic, cosmetics and other industries, wire bar film applicator has become an indispensable coating tool. In the adhesive industry, wire bar film applicator can accurately control the coating thickness of adhesive, improve the adhesion effect and product quality; in the ink or paint industry, wire bar film applicator can ensure the uniform distribution of ink or paint, improve the clarity and color saturation of printed matter; in the plastic industry, wire bar film applicator can be used to prepare thin film with uniform thickness, improve the performance and appearance of plastic products; in the cosmetics industry, wire bar film applicator can be used to prepare base material for various cosmetics, ensure the uniformity and stability of products.
[0004] In recent years, with the development of optoelectronic material technology, wire bar coating has been widely used in the preparation of functional materials for polymer solar cells / organic solar cells, electrochromic devices and other optoelectronic devices. Since wire bar coating technology and roll-to-roll coating technology have great similarities, wire bar coating technology is often used before roll-to-roll coating for large area production of coating film to simulate roll-to-roll coating and test the film forming performance of materials.
[0005] However, when using wire bar for manual coating, due to the difference between operators, even if the same wire bar and coating material, coating substrate are used, it is often impossible to prepare a film layer with the same performance, that is, the reproducibility of manual wire bar coating is poor. Therefore, related technical personnel introduce automatic film applicator, which is a tool that can provide stable and adjustable moving speed. When wire bar is used for coating with automatic film applicator, the shear rate and weight added to the wire bar remain unchanged during coating, thereby greatly improving the reproducibility of coating.
[0006] But in the current application design of automatic film coater and wire bar, most of them are fixed wire bar ends, and only from the two ends of the wire bar pressure, pressure is not adjustable, in the actual coating, often due to uneven stress of wire bar, resulting in uneven coating film.
[0007] Design and development of a convenient installation and removal of wire bar, and can make the pressure on the wire bar coating pressure adjustable, and the pressure on the wire bar can be evenly distributed wire bar fixing device, the automatic film coater and wire bar coating technology to solve the problem.
