Abstract
The invention provides a laser printing process with high efficiency, low cost and stable product quality. The laser printing process is performed on the same machine, and comprises the following steps sequentially: 1) unwinding; 2) coating the whole breadth of a film material or a specific position of the breadth with a laser imaging layer; 3) primarily solidifying the position coated with the laser imaging layer; 4) carrying out mold pressing on the laser imaging layer; 5) further solidifying the laser imaging layer; and 6) winding. Experiment proves that the laser printing process can be applied to a poly(ethylene terephthalate) (PET) or biaxially-oriented polypropylene (BOPP) film material, can effectively ensure the imaging quality of the product, has lower production cost and higher production efficiency, and is particularly suitable for enterprises which specialize in laser film processing.
Description
Technical field
The present invention relates to a kind of technology that on film, processes laser pattern.
Background technology
Have now and on packing film, process laser pattern, the processing method below general employing the: 1) on printing machine, unreel; 2) use the press printing picture and text; 3) on printing machine, the whole breadth of thin-film material or the ad-hoc location of breadth are carried out radium-shine imaging layer coating; 4) on printing machine, primary solidification is carried out in the position that scribbles radium-shine imaging layer; 5) rolling on printing machine; 6) on laser molding press, unreel; 7) with laser molding press thin-film material is carried out mold pressing; 8) on laser molding press, the position that scribbles radium-shine imaging layer is further solidified; 9) rolling on moulding press.
Above processing method; Generally be to consider that thin-film material is not limited in the production of a certain product carrying out the utilization that corresponding manufacturing procedure can make machine on the different machines; Running opportunity and time that therefore production manager can arrange machine flexibly, and the riding position of each machine of flexible design.But, from improving product quality, the energy-saving and cost-reducing and angle of enhancing productivity, there is the risk of infringement product quality in above production method, and the shortcoming that has that energy consumption is big, production efficiency is lower etc.
In the existing processing method; Applying radium-shine imaging layer carries out on printing machine; And molding laser pattern carries out on laser molding press, coats thin-film material behind the radium-shine imaging layer and need pass through primary solidification and rolling and just can be transferred to and carry out mold pressing on the laser molding press.But; The extruding force that receives the closer to the thin-film material of rolling up heart place is big more; Because radium-shine imaging layer is only by primary solidification, receive that the imaging characteristic of corresponding position is easy to be destroyed after the strong extruding force, make the imaging effect variation at this position; Though yet those skilled in the art know this problem phenomenon, do not recognize the origin cause of formation of this problem phenomenon.For reducing of the influence of this phenomenon, generally can adopt the method that improves molding temperature to product.But, improve the power consumption that molding temperature can increase machine, in addition the unwinding device on the laser molding press, carry-over pinch rolls device and deflector roll etc.; In fact with printing machine on corresponding device and equipment repeat to some extent; For the enterprise that specializes in radium-shine processing film, the mode of production of existing separate machined exists machine cost and human cost height, and machine and semi-finished product occupy-place are big; Shortcomings such as the machine energy consumption is big, thereby need to propose a kind of new process program.
Summary of the invention
The purpose of this invention is to provide a kind of high efficiency, low cost, and the radium-shine typography of constant product quality.
For achieving the above object, the technical scheme below the present invention has taked:
Radium-shine typography, on uniform machinery, carry out following steps successively:
1) unreels;
2) on the ad-hoc location of the whole breadth of thin-film material or breadth, coat radium-shine imaging layer;
3) primary solidification is carried out in the position that scribbles radium-shine imaging layer;
4) radium-shine imaging layer is carried out mold pressing;
5) radium-shine imaging layer is further solidified;
6) rolling.
In the above-mentioned production technology; Because the radium-shine imaging layer of thin-film material just enters into mold pressing procedure after primary solidification; Can do not pushed during this time by brute force; And at radium-shine imaging layer after the mold pressing after further solidifying, thin-film material just can be by rolling, radium-shine imaging effect was cured and can not be destroyed easily this moment.Therefore there is not the relatively poor problem of imaging effect at the volume heart place of thin-film material in this radium-shine typography.And compare with 140～200 ℃ general molding temperature; Show through experiment; Because process is continuous, this technology only need be increased to the temperature of forging printing plate roller 60～130 ℃ can mold pressing go out satisfied radium-shine printing effect, and energy consumption greatly reduces; Can effectively reduce production cost of products, strengthen the competitive advantage of product.
Be implemented on the thin-film material that is printed on picture and text and present laser pattern, only need in above-mentioned steps 1) with step 2) between adding picture and text print steps get final product.
Show that through experiment radium-shine typography of the present invention can be applicable on PET or the BOPP thin-film material.Can effectively guarantee the image quality of product, make that production cost is lower, production efficiency is higher.Especially be fit to specialize in the enterprise of radium-shine processing film.
The specific embodiment
Below in conjunction with embodiment content of the present invention is described further.
It is example that present embodiment has the thin-film material picture and text printing and BOPP that can present laser pattern with processing.The radium-shine imaging layer that it adopted is the UV coating; And the machine that is adopted comprise unwinding device, printing machine, coating unit, UV coating primary solidification device, molding device, UV coating advance rank solidification equipment, wrap-up and be arranged on the said equipment and device between deflector roll etc., the said equipment all can adopt existing equipment.
Carry out following steps successively at above-mentioned machine:
1) unwinding device unreels;
2) utilize printing machine on the BOPP thin-film material, to carry out the picture and text printing;
3) utilize coating unit on the whole breadth of BOPP thin-film material, to coat the UV coating;
4) utilize UV coating primary solidification device that the UV coating is carried out primary solidification;
5) utilize molding device that the UV coating is carried out mold pressing;
6) utilizing the UV coating to advance the rank solidification equipment further solidifies the UV coating;
7) wrap-up rolling.
In the present embodiment, the primary solidification device of step 4) is a single tube UV photo solidification machine, and the parameter of its primary solidification is following: exposure is 1/1000 second under the UV of 3.5KW light shines.The rank solidification equipment that advances of step 6) is 3 pipe UV photo solidification machines, and its parameter of further solidifying is following: exposure is 1/1000 second under the UV of 3*3.5KW light shines.Only carrying out under the situation of primary solidification, then the molding temperature of step 5) only need be promoted to 90 ℃ and gets final product, and the mold pressing energy consumption is compared with the mode of separating machining and declined to a great extent, and does not see the radium-shine imaging effect variation phenomenon near the film at volume heart place in the finished product.
This specification lists be merely preferred embodiments of the present invention, all equivalent technologies conversion of under operation principle of the present invention and thinking, being done all are regarded as protection scope of the present invention.
