Description

Technical Field

[0001] This utility model relates to the field of tape processing technology, specifically to an environmentally friendly flame retardant synthetic tape coating device. Background Technology

[0002] Environmentally friendly flame retardant synthetic tape is a type of flame retardant tape that has a minimal environmental impact during production, use, and disposal. Its main characteristics include halogen-free, low smoke, low toxicity, and good flame retardant properties. It produces low smoke and does not generate toxic gases when burning, exhibiting significant flame retardant effects. It also has good bonding strength, high temperature resistance, and chemical resistance.

[0003] In the coating process of flame-retardant synthetic tapes, the mixed adhesive and flame retardant need to be evenly applied to the surface of the substrate, which includes various materials such as polyester film and PVC film. The coating thickness needs to be controlled using a doctor blade during coating. In existing technologies, slight variations in the coating thickness are unavoidable. The doctor blade removes excess composite adhesive, but over prolonged use, adhesive buildup on the doctor blade surface can solidify or drip to both ends, affecting the precise spacing between the doctor blade and the adhesive, causing deviations and impacting the quality of the finished product. Utility Model Content

[0004] This invention aims to solve the aforementioned technical problem that adhesive accumulates on the surface of the scraper and easily solidifies or drips to both ends after prolonged use, and provides an environmentally friendly flame retardant synthetic tape coating device that facilitates the collection of excess adhesive.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: an environmentally friendly flame retardant synthetic tape coating device, comprising a rotating guide roller and a substrate, the substrate extending over the guide roller; and further comprising:

[0006] Operating platform; located above the guide roller and substrate, and connected to the end of the guide roller; the operating platform is provided with a rectangular through groove;

[0007] A pressure roller is rotatably connected within a rectangular through groove, with its lower end in rotatable contact with the substrate.

[0008] Adhesive guiding assembly; including a collection box located on the operating table, the collection box having an elongated opening at one end near the pressure roller, an inclined scraper connected to the outside of the opening, the outside of the scraper contacting the pressure roller; a pusher plate that moves horizontally inside the collection box, and an outlet pipe connected to its end.

[0009] Furthermore, each end of the guide roller is provided with a fixing plate, and each fixing plate is provided with a column. The outer side of each column is provided with a thread and is threaded to two nuts. A sliding plate is provided between the two nuts and on the outside of the column. Each sliding plate is fixedly connected to one end of the operating table.

[0010] Furthermore, the operating table is provided with mounting plates on both sides, and the pressure roller is provided with shafts at both ends, which are rotatably connected to the corresponding mounting plates; one of the shafts extends out of the mounting plate and is provided with a drive motor.

[0011] Furthermore, the longitudinal section of the scraper is triangular.

[0012] Furthermore, the collection box is provided with symmetrical mounting plates two near both ends, one of which is provided with a drive motor two on its outer side, and the output end of the drive motor two extends to the space between the two mounting plates two with a threaded rod; a nut block is threadedly connected to the outer side of the threaded rod, and the lower end of the nut block extends into the collection box and is connected to the push plate.

[0013] Furthermore, the collection box is provided with a strip groove capable of accommodating the nut block; the front and rear sides of the push plate are in contact with the front and rear sides inside the collection box.

[0014] The advantages of this utility model compared with the prior art are as follows:

[0015] After setting the distance between the pressure roller and the guide roller, the excess adhesive on the substrate can be pushed out and gradually removed by rotating and squeezing. After being removed, it is continuously scraped off by the scraper on the rear side, so that the distance between the pressure roller and the guide roller is constant and not easily affected by the accumulated adhesive.

[0016] The scraped adhesive can be pushed out and collected for reuse while it is solidifying. Attached Figure Description
