Double-sided coating equipment and processing technology applying double-sided coating equipment

Abstract

The invention relates to double-sided coating equipment. The double-sided coating equipment comprises front-side coating equipment and back-side coating equipment, wherein the back-side coating equipment comprises a second rack, and a first guide roller, a traction roller, a second guide roller and a second coating roller which are sequentially distributed below a base material in the back-side coating direction of the base material are erected on the second rack; and a glue tank used for infiltrating part of the second coating roller is arranged under the second coating roller, the second guide roller is arranged on one side of the second coating roller, a second scraper is fixed to the other side of the second coating roller, the blade point of the second scraper is connected with the outer surface of the second coating roller in an abutting mode, the front-side coating equipment is located below the back-side coating equipment, and a middle roller is positioned between the front-side coating equipment and the back-side coating equipment. According to the high-efficiency double-sided coating equipment and a processing technology applying the double-sided coating equipment, double-sided coating can be achieved on one coating line.

Description

technical field [0001] The invention relates to the technical field of coating, in particular to a double-sided coating equipment and a processing technology using the double-sided coating equipment. Background technique [0002] The coating and compounding equipment in the prior art is mainly used for gluing coating and compounding processing of various roll substrates such as plastic film, paper, anodized aluminum, cloth and leather. It is widely used in various packaging fields and has broad development prospects. There are three types of coating compound equipment: gluing coating on spectroscopic roller, gluing coating on anilox roller and extrusion coating with hot melt adhesive. [0003] Smooth roll size coating This type of size coating is usually two-roll transfer coating. Adjust the gap between the upper rubber roller and the coating roller to adjust the amount of coating. The structure of the entire coating head part is relatively complicated, requiring high pro...

Problems solved by technology

The traditional coating mechanism can only perform one-sided coating, which is inefficient. If you want double-sided coating, you can only repeat the coating process on a single coating equipment, so that the efficiency of double-sided coating equipment is at least doubled. , also has the advantages of reducing manual operation, reducing the substrate loss of repeated equipment on the substrate, reducing the number of oven drying, reducing energy consumption, etc.
