Laminating equipment for pvc laminated floor

Abstract

The invention discloses a laminator for PVC laminated floorboards. The laminator is characterized in that the laminator comprises a calendering mechanism and a traction mechanism, the calendering mechanism comprises a frame, a roller opening and closing mechanism and a horizontal four-roller calender assembly, the horizontal four-roller calender assembly sequentially comprises a first smooth roller, a second smooth roller, a network roller and a pattern roller, the traction mechanism comprises a left wallboard, a right wallboard and a traction system, the traction system comprises a cylinder compacting device, an upper steel roller, a lower glue roller and a lower glue roller driving device, and the lead-out outlet of the traction mechanism faces the network roller. The laminator has the following advantages: the temperature at the network roller is 100-110 DEG C, and the reduction of the temperature reduces the film deformation; and the arranged synchronous traction mechanism component makes the product discharge speed of the calendering roller of the calender same to the film discharging speed of the traction mechanism, so the tensile stress of the film in production is eliminated, and the defect of insufficient coverage of the product, caused by transverse shortening of the film, is avoided, thereby the yield of the product is greatly increased.

Description

technical field [0001] The present invention relates to a kind of PVC floor production equipment, more specifically, it relates to a kind of film-coating equipment of PVC film-coated floor. Background technique [0002] PVC flooring is a new type of light-weight ground decoration material that is very popular in the world today, also known as "light-weight ground material". It is a popular product in Europe, America, Asia, Japan and South Korea. It is popular abroad. It has entered the Chinese market since the early 1980s. It has been widely recognized in large and medium-sized cities in China and is widely used, such as homes, hospitals, Schools, office buildings, factories, public places, supermarkets, commercial, stadiums and other places. Specifically, polyvinyl chloride and its copolymer resin are used as the main raw materials, and fillers, plasticizers, stabilizers, colorants and other auxiliary materials are added to the sheet-like continuous substrate through coati...

AI Technical Summary

Problems solved by technology

[0006] In the laminating device, the film unwinding reel is in a free state. When the calender roller pulls, due to the rotational resistance caused by the weight of the film unwinding reel, the film generates tensile stress, and this longitudinal tensile stress makes the film longitudinally elongate. , the horizontal shortening, the self-weight of the film unwinding drum is constantly changing due to the continuous change of the size of the film roll, and the rotational resistance is also constantly changing, resulting in the pattern deformation of the color pattern film. At the same time, due to the lateral shortening, when the two-layer film is combined

Horizontal size is not enough

And the above changes are uncertain. When the PVC sheet is extruded from the mold, the temperature is 160-170 degrees. At this high temperature, the film deformation is more serious, which eventually leads to unqualified products.
