Description
Technical field
The present invention relates to a kind of used in the coating unit and production technology that blow inside prestige membrane equipment.
Background technology
In order to improve the physical and chemical performance of agriculture greenhouse film, people would generally after agricultural booth film extruding forming,
The surface of agriculture greenhouse film is coated with some liquid with modified function (also known as " feature masking liquid "), these feature masking liquids
Solidified forming is functional coat.Common feature masking liquid has anti-drip agent liquid, antifogging agent liquid etc..For example, anti-drip agent liquid,
The coating effect that antifogging agent liquid is formed is as follows：Due to agriculture greenhouse film in use, steam is easily on the surface of awning film
Condensation, not only hinders the transmission of light, and the water droplet that can build-up ice in low temperature affects the normal life of crops in crop surface
Produce, and these functional coats can reach effect of anti-drip, preventing atomization, solve above-mentioned condensation, drop frozen water, shading etc. and ask
Topic.
Implementing the device of coating functions masking liquid becomes coating unit, and coating unit is arranged under agricultural booth film production line
Trip, online painting is covered with feature masking liquid after agriculture greenhouse film production molding, and is solidified into functional coat, then wind again or
Collect.
The technique of agriculture greenhouse film coating functions coating, it is necessary to be precisely controlled the coating thickness of feature masking liquid, so as to reach
To the effect of environment-friendly high-efficiency.It is equal including the coating thickness on control agriculture greenhouse film two sides, and control agriculture greenhouse film is in length and breadth
Each position coating thickness upwards is uniform.
The coating unit structure and coating processes of existing agriculture greenhouse film functional coat is as follows：In sided corona treatment mechanism
Downstream arranges and applies liquid bath, and in the downstream for applying liquid bath drying mechanism is provided with；One or some interior deflector rolls are installed in liquid bath is applied, are applied
Functional liquid is loaded with liquid bath, the ball-cock assembly that liquid bath is provided with control function masking liquid is applied, so that feature masking liquid liquid level keeps steady
It is fixed.After agricultural booth film extruding forming, sided corona treatment is carried out online immediately, make agriculture greenhouse film surface become coarse, produce more
Many micropores, first run from top to down through the plastic film for agricultural use of sided corona treatment, in painting liquid bath, after bypassing interior deflector roll lower surface,
Painting liquid bath is left after running from bottom to top again, vertical drying device is eventually passed, makes feature masking liquid solidify to form feature painting
Layer.
But there is three below in existing coating unit structure and coating processes：
First, the coating thickness on agriculture greenhouse film two sides is not reciprocity, and wherein inner surface (side of deflector roll in contacting) is applied
Cover that thickness is less, and outer surface (not contacting the side of interior deflector roll) coating thickness is larger, causes the painting thickness on thin film two sides
Degree is uneven.
2nd, the coating thickness of agriculture greenhouse film cannot regulate and control in the vertical uniformly.Agriculture greenhouse film is in feature masking liquid
The speed of service influence whether that the more fast then coating thickness of coating thickness, the i.e. speed of service is less, conversely, the speed of service is more slow, apply
Cover thickness bigger.And the speed of production of agriculture greenhouse film occurs in process of production fluctuation, cause thin film in feature masking liquid
In the speed of service unavoidably there is fluctuation, and then cause the coating thickness at each position ripple vertically and horizontally occur along plastic film for agricultural use
It is dynamic.Existing coating unit and coating processes cannot carry out active correction regulation and control to the fluctuation of this coating thickness.
3rd, in existing coating unit structure and coating processes, affected by device, one can only be carried out to agriculture greenhouse film surface
Plant the coating of feature masking liquid, it is impossible to carry out two kinds even coating of several functions, i.e., under existing apparatus, by increasing work(
The method of energy property masking liquid kind cannot be realized come the correlated performance for increasing or improving agriculture greenhouse film.
4th, existing coating unit structure and coating processes, rely primarily on thin film carries out surface by the dip roller in masking liquid
Coating, it is impossible to control the coated weight of film surface, it is impossible to upper to realize quantitative control, the stability of coat cannot be stablized,
And waste larger.
