Combined embossing technology and equipment of polyvinyl chloride (PVC) sheet

Abstract

The invention discloses combined embossing technology and equipment of a polyvinyl chloride (PVC) sheet. The compound embossing equipment comprises a surface membrane unwinding mechanism, a basement membrane unwinding mechanism and a winding mechanism, wherein a surface membrane preheating roller wheel is arranged in the rear of the rear surface of the surface membrane unwinding mechanism; a basement membrane preheating roller wheel is arranged in the rear of the rear surface of the basement membrane unwinding mechanism; first roller wheels of the surface membrane preheating roller wheel and the basement membrane preheating roller wheel are both provided with rubber rollers; a combined vat is arranged in the rear of the surface membrane preheating roller wheel and the basement membrane preheating roller wheel, and the rubber rollers are arranged with the combined vat together; a conveying roller is arranged in the rear of the combined vat; an embossing roller is arranged in the rear of the conveying roller, and the rubber rollers are arranged with the embossing roller together; and the winding mechanism is arranged in the rear of the embossing roller. Compared with the prior art, surface membrane unwinding and preheating is a path, basement membrane unwinding and preheating is an other path, the two paths are finally met together on the combined vat, combined by the combined vat and embossed by the embossing roller, and the whole production process is automatically carried out, thus the invention saves a large quantity of manpower, greatly enhances the production efficiency and the product quality and reduces the defective product ratio.

Description

technical field [0001] The invention relates to PVC sheet compound embossing technology and related equipment. Background technique [0002] The surface of PVC sheet needs to be embossed to look beautiful. The traditional embossing method is to use a plastic film that has been printed with wood grain and embossed and weather-resistant on the surface on a plastic laminating machine. Apply glue, heat and pressurize to make the color film and PVC different sheets bond together. This kind of lamination can be carried out immediately after the PVC sheet is extruded, or another production line can be set up for lamination. The entire composite operation must be within a certain temperature and time range, otherwise the quality of the product will be reduced. Therefore, the equipment used in the traditional technology is too complicated, the operation process is not smooth enough, and many operations need to be performed manually, which not only cannot guarantee the quality, but ...
