Production equipment for PVC composite coated floor

Abstract

The invention relates to production equipment for a PVC composite coated floor. The production equipment comprises a cooling roller set used for cooling a PVC base layer obtained after rolling, an outlet of the cooling roller set is connected with the front end of a composite roller through a conveying belt, a printing layer lead-in roller and abrasion layer lead-in rollers are arranged at the rear end of the composite roller, an outlet of the composite roller is connected with a heating device through a conveying roller set, corresponding lines are formed on the surface of a PVC film heated through the heating device through an embossing roller, a cooling and shaping device for cooling and shaping the PVC film is arranged at an outlet of the embossing roller, the PVC film out of the cooling and shaping device is subjected to surface treatment with a UV device, a back-fire device is arranged on a rear channel of the UV device, and the PVC film out of the back-fire device enters a cutting machine to be cut. The investment of the equipment can be reduced, and the production process can be simplified; meanwhile, the stability, smoothness and abrasive resistance of the composite floor can be ensured, and the service life can be prolonged.

Description

technical field [0001] The invention relates to the technical field of PVC flooring, in particular to production equipment for PVC composite film-covered flooring. 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 coating process or calendering,...

AI Technical Summary

Problems solved by technology

The process is complicated and the stability is not high, which directly affects the improvement of product quality and production efficiency.

The production equipment involved in the whole production line mainly includes internal mixers, calenders, multi-layer presses and other machines. In order to ensure a certain production efficiency, several hot presses are required. The internal mixer with a volume of 80L is the most For example, its theoretical production capacity is 675Kg / h, and the production capacity of 24-hour continuous work is 16.2 tons. Each PVC multi-layer press machine can press 2.5 tons of PVC boards with 24-hour continuous work. One internal mixer needs to be equipped with 7 sets of PVC The multi-layer press can reach the maximum production capacity. The price of an internal mixer is about 800,000, and the price of a PVC multi-layer press is about 280,000. The entire production line is based on the internal mixer and the PVC multi-layer press. The investment needs about 2.76 million, plus the investment of boilers, calenders and other equipment, it needs at least 4 million. The investment cost of equipment is high and the production process is complicated.

Moreover, the investment in equipment is large, the investment in the required plant area is huge, and the production cost is high
