Description
Technical field
The present invention relates to medical film production field, more particularly to a kind of laboratory at the uniform velocity apparatus for coating.
Background technology
At present, the method needed for masking liquid being continuously and uniformly coated on substrate surface probably has following several：Dip-coating, roller
Formula coating, scraper type coating, the coating of comma formula, gravure, slit coventry type die head coventry are extrusion coated, the coating of metering bar type, spraying
Formula is coated with and other rotary coatings.It is wherein relatively broad for print roll coating, scraper type coating, gravure and slit
Die head is extrusion coated.
Print roll coating due to be difficult stablize all the time it is rotating transfer roll surface on defined thickness formed transfer film, because
This scrapes transfer film unnecessary on transfer roll surface with scrubber, to ensure defined transfer thickness.So that the utilization of coating material
Rate reduces, and increases production cost.
Fixed dimension gap between scraper and top surface based on scraper for coating, so using the coating method meeting
It is higher to the thickness requirement of base material, if base material itself became uneven may result in the inequality of coating weight on base material, and scraper for coating
The higher coating of suitable viscosity.
Gravure is a kind of relatively good coating method in actual production, but also has the drawbacks of certain.Intaglio plate formula
Coating is for the cleanliness factor of coating environment, the stability of coating system, speed and tension force precision, the homogeneity of material and base
The homogeneity of material has high requirement, while is not also suitable for the coating of some difficult cleanings of easily attachment.
The coating of slit coventry type die head coventry basis, is generally divided into slope flow coat cloth and curtain coating.Wherein, curtain coating is slope flow coat cloth
Upgrade version, a variety of coating fluids can be made while coating forms composite coating, but both coatings for technological requirement all very
The high coating fluid of high and unsuitable viscosity, it is just the opposite with scraper for coating.The enterprise of coating head is carried out also just with regard to current state's interior energy
It is Lekai, if it is desired to which with the method, it is necessary to reference learning foreign technology, and price is not cheap.
The easy apparatus for coating used as laboratory, is generally all coated with using bar.Traditional squash type bar is all
Close finer wire is wound in the just face of rod iron to carry out, it is thick by the diameter of finer wire and the precision control coating of winding
Degree.Now new-type bar is typically all to use precision die, and bumps are processed on rod iron surface using cold extrusion processing technology
Uniform wavy curve, plays the Painting effect identical with traditional bar.Since its surface does not have finer wire winding, no
Have the sorrow that steel wire loosens and its surface curve lubrication is smooth, easy to clean, can be generally coated after it installs handle additional.
However, firmly uneven, coating speed per hour inequality is made every time when during realistic individual is operating process due to hand coatings
Into Painting effect gap it is larger, it is therefore desirable to using machinery replace manual application accomplish and uniform force application it is controllable, coating speed per hour
Uniform, controllable is within the scope of certain.
The coating machine price of use for laboratory is higher on the market now, the more complicated working service of mechanical structure and cleaning
All cumbersome, the mode that uses of motor transmission is more complicated and coating accuracy not easy to control.
Guide wheel person and mechanical structure are installed additional using screw structure and in ball line slideway slide unit, can ensure precision
Conduction is become simple and stable at the same time, and oneself can make manually without purchase.
