Problems solved by technology

[0008] The surface of the anilox roller has a mesh structure, which can accurately measure the adhesive and curing glue. For the solvent-free glue, if you want to achieve accurate coating, you must improve the coating accuracy and solve the problem of low transfer rate of the anilox roller to the solvent-free glue. The problem

Embodiment 1

[0038]This embodiment relates to a continuous coating mechanism for continuous coating of solvent-free curing glue (hereinafter also referred to as curing glue) on both sides of a flat product. The two groups of continuous coating mechanisms pass through continuously. During the passing process, the solvent-free curing glue is continuously coated on the surface of the flat product by the continuous coating mechanism.

[0039] The continuous coating mechanism includes an anilox roller 2, two rubber transfer rollers (4, 5), a glue supply nozzle 12, a scraper mechanism 1 and a cleaning spray suction pipe 7, two rubber transfer rollers (4, 5). 5) are smooth rollers, which are respectively arranged at the upper and lower positions of the anilox roller 2 and are in rolling contact with the anilox roller 2 respectively. The glue supply nozzle 12 is connected with the automatic glue supply system 8. The function of the automatic glue supply system 8 is to quantitatively supply glue to...

Embodiment 2

[0051] like Figure 5 As shown in the figure, the anilox roller can be designed to be able to rotate both clockwise and counterclockwise. Therefore, two scrapers need to be set up to cooperate with the anilox roller 2 when the anilox roller 2 rotates clockwise. Works in conjunction with anilox roll 2 rotating counterclockwise. Makes anilox roll gluing more flexible.

Embodiment 3

[0053] This embodiment involves the matching sizing structure of the anilox roller 2 and the pressing roller 14, such as Figure 7 As shown in the figure, the anilox roller 2 is provided with a constant temperature spacer 10, and the pressure roller 14 is also provided with a constant temperature spacer 10. A flat product such as a film is continuously wound around the pressing roller 14, and the pressing roller 14 squeezes the film to the surface of the anilox roller 2. During the extrusion process, the solvent-free cured glue in the grid on the surface of the anilox roller is squeezed onto the surface of the film.

[0054] In this embodiment, the anilox roller 2 rotates counterclockwise, the scraper mechanism 1 is arranged on the left side of the anilox roller 2, and the pressing roller 14 rotates clockwise.

Abstract

The invention relates to a continuous coating mechanism for a solvent-free curing adhesive coating layer. The continuous coating mechanism comprises an anilox roller, an adhesive supply spray pipe, a scraper mechanism and a cleaning spray and suction pipe; the coating mechanism is arranged on one side or two sides of a planar product and can be used for simultaneously coating one side or two sides of the planar product with a solvent-free curing adhesive; the glue supply spray pipe applies solvent-free curing adhesive liquid to the surface of the anilox roller, the scraper mechanism makes contact with the anilox roller to evenly scrape the solvent-free curing adhesive on surface of the anilox roller, and the rotating anilox roller directly or indirectly transfers and coats the the adhesive liquid onto the surface of the planar product; and the cleaning spray and suction pipe applies a diluent to the surface of the anilox roller to dilute residual adhesive on the surface of the anilox roller and in an adhesive tank, and sucks and discharges the solution diluted with the residual adhesive from the surface of the anilox roller. When the process is stopped, by spraying the solvent to the surface of the rotating anilox roller, the curing adhesive cured in meshes in the surface of the anilox roller is re-dissolved, so that online cleaning of the anilox roller is achieved, and the problems that a plate is easy to block and difficult to clean when the anilox roller is adopted for coating the solvent-free curing adhesive are solved.

Description

technical field [0001] The invention relates to a coating mechanism for accurately coating solvent-free curing glue on the surface of flat products. Background technique [0002] Environmentally-friendly production is an important upgrade content for enterprise development. Reducing exhaust gas, waste water and waste discharge from factories will help reduce environmental pressure. This limits the application of traditional solvent-based coatings and adhesives (also known as cured adhesives), because such solvent-based products will continuously release volatile solvents during coating and later use. Potential environmental stress and human health risks. Therefore, solvent-free curing adhesives (also referred to as solvent-free adhesives in the text) are considered to be environmentally friendly adhesives because they do not contain or contain very little solvent, and are being favored by the market. [0003] Solvent-based glue contains solvent, so it has good fluidity and...
