Polyurethane automobile paint surface protective film, and multifunctional coating equipment and compounding process thereof

Abstract

The invention relates to the technical field of protective film production equipment, and especially relates to multifunctional coating equipment of a polyurethane automobile paint surface protectivefilm. A comma scraper coating assembly and a slit extrusion coating assembly are arranged on the left side of a rack, a reverse micro-concave coating assembly, a first winding assembly, a first roll feeding assembly, a first unwinding assembly, a third winding assembly, a cooling traction assembly, a composite traction assembly, a second unwinding assembly, a second roll feeding assembly and a second winding assembly are sequentially arranged on the rack from left to right, and a drying heating box is arranged at the top of the rack. According to the equipment, interfaces and components are reserved, three different film running routes are adopted to meet different production process requirements, multiple functions are achieved through one machine, the equipment is reasonable in structural position design, the function of each mechanical part is achieved most efficiently, the working efficiency and the product quality of the equipment are greatly improved, capital invested by customers in the earlier stage is reduced, and the occupied area of the equipment is reduced.

Description

technical field [0001] The invention relates to the technical field of protective film production equipment, in particular to a multifunctional coating equipment for polyurethane automotive paint surface protective film. Background technique [0002] Car paint protection film, also known as "invisible car cover", is a layer of transparent protective film attached to the surface paint of the car to protect the original car paint of the car from damage. This product has strong toughness and self-healing function, which can effectively prevent scratches and sand hits, and also isolates the contact between the car paint and the air, and can prevent acid rain, asphalt, bird droppings, etc. from damaging the paint surface . At the same time, the paint protection film is high-definition and bright, which can improve and protect the color and luster of the car paint surface. [0003] At present, most manufacturers need multiple coating equipment to complete the production and manu...

AI Technical Summary

Problems solved by technology

[0003] At present, most manufacturers need multiple coating equipment to complete the production and manufacture of urethane automotive paint protection film. A lot of manpower and material resources are invested in the early stage, and the area occupied by multiple mechanical equipment is relatively large. It is extremely inconvenient to replace the film roll
