Antistatic master batch coating device for CPP film processing

Abstract

The invention belongs to the field of film processing, and specifically relates to an antistatic master batch coating device for CPP film processing. The antistatic master batch coating device comprises a box body, spreading rollers are installed on the left upper side and the right upper side of the box body, the two sets of vertically adjacent spreading rollers are tangent to each other, through holes are formed in two sides of the top of the box body correspondingly, guide rollers are installed on two sides of an inner cavity of the box body correspondingly. Spray heads and a drying shell are installed between the two sets of guide rollers, and the number of the spray heads is two. According to the antistatic master batch coating device, the amount of sprayed paint is set through a controller, and therefore spraying of different thicknesses can be conducted according to different films, and adaptability is high; and meanwhile, spraying of different thicknesses can be conducted on different parts of a single set of films, in the spraying process, and the controller can accurately adjust a temperature controller according to the spraying amount. The drying temperature for the positions with different thicknesses changes accordingly, and therefore the drying effect is guaranteed, drying can be thorough, and the quality of later-stage products is effectively guaranteed.

Description

technical field [0001] The invention relates to the field of film processing, in particular to an antistatic masterbatch coating device for CPP film processing. Background technique [0002] CPP film is cast polypropylene film, also known as unstretched polypropylene film, which can be divided into general CPP film, aluminized grade CPP film and cooking grade CPP film according to different uses. The polypropylene film produced by the process, which is different from the BOPP film, is a non-oriented film. Strictly speaking, the CPP film only has a certain orientation in the longitudinal direction, mainly due to the nature of the process. Cooling to form excellent clarity and smoothness on the film. CPP film needs to be coated with antistatic masterbatch on the surface, which can reduce the resistance of the object surface and improve the effect of CPP film use. The antistatic masterbatch for CPP film processing on the market is currently Material coating device Some devices...

Problems solved by technology

[0004] During the use of the above-mentioned patents; although the sprayed liquid is quickly solidified by drying, due to the different thicknesses of different films and different positions of the film, accurate drying cannot be performed during the drying process. As a result, incomplete drying is prone to occur, which affects the quality in the later stage, and in the actual use process, the film is prone to wrinkles due to insufficient tension during the transmission process, which affects the spraying effect
