Description
Technical field
Be not in bubble the utility model relates to one kind, and effectively prevent the curtain coating for the casting machine of dry hide phenomenon occur
Head.
Background technique
Casting machine is a mechanical equipment towards rubber-plastics material cast film product molding, is mainly used for cast film system
The fields such as product molding, the development of tape casting material prescription, the research of tape casting material property, are such as transported to curtain coating mechanism for material
Take cast film product etc..It is widely used casting machine, may be used as PE film production various product, especially paper diaper, defends
The disposable products such as raw towel, medical protection clothes.Be cast machine equipment feature: 1. concentrate panel operation, integrated circuit control.Casting machine
Equipment each section concentrates on panel operation control.2. panel major function: the adjustment of the A. speed of mainshaft；B. winding length setting；C.
Unwinding tension adjustment；D. winding tension is set；Starting.Stop button.3. cutter uses upper lower round knife, and can be according to different
Cutting width replaces lower edge bearing, adjusts cutting width to reach the cut quality of high-quality.
With the development of microelectric technique, photoelectron technology and power electronic technique, electronic ceramic film or substrate are wide
It is used for lamination sheet type capacitor and inductance generally.These films or substrate are cast on casting machine using ceramic slurry, no
Curtain coating theory of mechanics used in stack pile and the film or substrate of function is slightly distinguished, and the precision of casting machine and efficiency are not yet
Together, especially reach 10m in casting thickness hereinafter, thickness error is in the casting films manufacturing process of 1~4m, in addition to that must have strictly
Technique and Environmental Support other than, it is often more important that have high-accuracy curtain coating mechanized equipment.
Casting machine generally includes fuselage, unwinding system, winding system, feeding system, drying system, control system and base
Band film.Influence the principal element of casting machine device product quality are as follows: the viscosity of slurry, the gap of scraper, slurry storage tank liquid level
Highly, the speed etc. being cast.These factors all substantially solve at present.There is presently no the big problems well solved to be,
It being produced under equal conditions, the liquid level of slurry storage tank increases, and the pressure in slurry storage tank with regard to big, just accelerate by the speed of slurry outflow,
Pressure at curtain coating mouth is consequently increased, and accelerates slurry by the speed of scraper gap, and curtain coating film thickness in this way is increased by, raw
The casting films that output is come will be in uneven thickness, influences the quality of product.
Utility model content
Purpose of the utility model is to solve disadvantages existing in the prior art, and the one kind proposed is not in gas
Bubble, and it effectively prevent the curtain coating head for the casting machine of dry hide phenomenon occur.
A kind of curtain coating head of casting machine, comprising: rotor, casting roller, film strips and magazine are arranged on casting roller and follow curtain coating
Roller rotates counterclockwise and the film strips that are driven, and the adjustable rotor with casting roller gap, rotor and curtain coating are equipped with above casting roller

Further, the length of cavity and the length of rotor cooperate.
Compared with prior art, technical solutions of the utility model have the beneficial effect that first is that discharge port be higher than feed inlet, object
Material passes through sluice way to overflow, so that discharge port uniformly flows out, it is not in bubble and dry hide phenomenon；Second is that being withstood using screw
Blade pressuring plate will be scraped knife plate and be pressed on rotor, is convenient for changing and scrapes knife plate, facilitates adjusting and calibration scraper precision, scrapes knife plate and be not necessarily to
Punching, it is possible to select high hardness material and special material to make, prevent from scraping made of special material knife plate can not weld,
It is frangible to press, can not punch；Third is that scraping knife plate using the structure that the edge of a knife is thin, main body is thick, because scraper plate thickness will not deform, knife
Mouth is thin to can achieve high-precision curtain coating effect；Fourth is that casting slurry first passes through scraper because the cutting edge for scraping knife plate is higher by doctor roll
The height of roller carries out first time curtain coating, carries out secondary curtain coating using the cutting edge for scraping knife plate of protrusion, curtain coating precision is high, to liquid level
Requirement it is not harsh, can reach ultrathin membrane and thick film curtain coating, casting thickness range 20um-1200um；Fifth is that magazine is fitted in knife
Between roller and the gap of casting roller, belong to vertical plane with the clearance fit for scraping knife plate and be bonded, reaches that scrape will not when knife plate moves up and down
Spillage；Sixth is that scraping, knife plate is longer than magazine and rotor, and the slurry come out from magazine all spreads to the same height by knife plate is scraped, and solves
Because of the phenomenon of slurry height injustice caused by spillage, solves and adjust uneven caused by height curtain coating spillage ask because scraping knife plate
Topic；Seventh is that discharge port is lower than casting roller highest point, it is driven using film strips, the material for taking away discharge outlet is uniformly attached to film strips
On.
