Abstract
The present invention discloses a film printing manufacturing method and a film printing manufacturing apparatus. The film printing manufacturing method comprises: drying to dry a plastic raw material composition; heating to melt the plastic raw material composition so as to obtain a gelling composition; extruding to extrude the gelling composition; performing a blowing-film forming step to blow the gelling composition by using a gas so as to obtain a sheet composition; flattening to carry out calendaring on the sheet composition so as to obtain a film half-finished product; carrying out a first printing step to print one surface of the film half-finished product so as to obtain a film printing product; cutting to cut the film printing product; and rolling to roll the film printing product so as to obtain the film. According to the present invention, the waste of the transportation time can be reduced, the problem that the non-printed film half-finished product is broken due to the external force pulling can be reduced, and the time and the cost can be saved.
Description
Technical field
The invention relates to a kind of film-forming method, particularly relate to manufacture method and the device thereof of a kind of film printing.
Background technology
Progress along with science and technology, plastic product is closely bound up with the life of people, such as sporting goods, clothes, appliance and electronic, or the container that various packaged food contains or preserves uses, by the characteristic that can change pliability, shape, make it apply quite extensive, and become article indispensable in life.
The manufacturing process of plastics is first to be melted by plastic raw materials, extrude with screw rod again, blown the balloon pipe forming a plastic sheeting by the die head of inflation film manufacturing machine, the most further manufacture size, thickness, variform plastic, to coordinate various different situation to use with occasion.
Refering to Fig. 1, inventing No. 327956 patent for TaiWan, China and " utilize the manufacturing method thereof of blown film mode extrusion shrink film ", this Patent Case is mainly incited somebody to action: a. polyester material is inserted extrusion molding machine and melt extruded；B. through die head extrusion Hou Shang blow molding thin film, through vane cooling and shaping or horizontal mode extrusion one of them；C. molding curtain is utilized to guide thin film to the thermal treatment zone；D. thermoplastic thin film；E. utilize secondary inflation power that thermoplastic thin film is carried out certain multiple inflation.
Whereby, making material be easier to stable processing, improve shrinkage factor, during overcoming blown film, film body became uneven causes thin film stability the best, and drops the puzzlement of low production yield.
Via above narration, it is known that the existing manufacturing method thereof utilizing blown film mode extrusion shrink film still has following shortcoming when actually used:
One, efficiency is the best
Though upper blow molding is utilized existing, make the more agravic effect of finished product of institute's extrusion, and reach the uniform effect of thickness, but, in order to make this thin film have specific pattern, to meet the demand of different aesthetic property, it is necessary for this thinfilms scroll-like relation, and delivers to printing house to carry out next step, thus, not only can increase the freight charges of transport, more prolongation operating personnel be waited the time of operation, and reduces the efficiency of processing procedure.
Two, film body easily sticks together
It is wound into the thin film of shaft-like, easily because being stored in the environment of warm, or storing overlong time makes this thin film aging, the film body causing this thin film sticks together the most mutually or lumps, expansion is made to become difficulty, even cannot launch, so will result in the puzzlement in manufacture, and increase the expenditure of manufacturing cost.
Three, operation inconvenience
When the presswork to be carried out of the thin film of reel, this thin film need to be positioned on the wheel shaft of a printer, again this thin film is pulled out, send in this printer and print, during except need to carefully adjust the position that this thin film is positioned on this printer, with avoid produce printing error, more need cagily to pull out this thin film, reduce this thin film to be pullled by external force and rupture, not only increase the degree of difficulty of operation, the most do not have convenience.
Four, processed is discontinuous
Although early having printer technology miscellaneous on the market, but it is independent individual machine with existing inflation film manufacturing machine, the most even it is positioned at different Factory Buildings, therefore, the linking control problem of machinery compartment need to be overcome, although by transporting to complete presswork, but the processed of coherency can be unable to reach, and easily cause unnecessary time consume and waste with cost.
Disadvantages mentioned above all manifests the variety of problems that the existing manufacturing method thereof utilizing blown film mode extrusion shrink film is derived on using, if designing the shortcoming that can be effectively improved existing blown film processing procedure, develop a kind of design shortening processing time and improving production efficiency, must reach to put forward high efficiency target, create bigger business opportunity for dealer, and then promote the competitiveness on market.
