A kind of composite technology for fixed length stretching
Technical field
The present invention relates to the trans-printing technical field, be specifically related to a kind of composite technology for fixed length stretching.
Background technology
In the prior art, trans-printing is with attached to the epilamellar coating that has graph text information, by technologies such as gluing, roll extrusion, oven dry on the film aluminium lamination, graph text information is transferred to process on the paper.Because graph text information is to be produced on the version, the size of every version all has fixing size, if galley is stamped on the above-mentioned basement membrane continuously by cylinder, when the cylinder that is loaded with graph text information is impressed in the epilamellar process that scribbles the image layer in transfer, because the distortion of basal lamina material self, the variation of tensile stress, and the various distortion that in the stamp transfer process, produce, the capital makes certain difference that continuous embossed size between epilamellar each domain literary composition information all exists, the accumulated error of above-mentioned difference will cause being loaded with the graph text information forme and is stamped into version and sews on.Therefore, be necessary that the control technology of version kerf spacing is improved in the existing transfer printing technology.
Summary of the invention
The objective of the invention is to overcome defective of the prior art, design a kind of composite technology for fixed length stretching.This technology can be controlled the size between the basement membrane upper plate seam effectively, thereby can improve the product quality of trans-printing and give birth to tea efficient.
For achieving the above object, technical scheme of the present invention is to adopt a kind of composite technology for fixed length stretching, and described technology comprises the steps:
S1: on basement membrane, be coated with the imaging coating, adopt mould pressing process that the perfect information on the silver-colored face nickel version is stamped on the described imaging coating and make holography shifting film;
S2: on described basement membrane, be provided with and publish seam, the distance between the described version seam is controlled between 50.53mm~50.62mm;
S3: described holography shifting film is installed between the transfer membrane let off roll and transfer membrane stretching and drawing rod in the fixed length stretching machine set composite;
S4: in the described fixed length stretching machine set composite, near described transfer membrane let off roll, be provided with upper glue roller and paper let off roll, near described transfer membrane stretching and drawing rod, be provided with Paper tractor roller and compound milling roller, described paper is installed between described paper let off roll and the described Paper tractor roller;
S5: be provided with photoelectric sensor between described transfer membrane stretching and traction roller and described glue spreading system, described photoelectric sensor is used to detect the signal of described version seam, and sends the signal of described version seam in the described fixed length stretching machine set composite control circuit;
S6: described control circuit is published the physical length of version between seam according to the calculated signals of the detected version seam of described photoelectric sensor, and in the physical length of described version and the memory edition length is compared;
S7: described control circuit is according to the described comparative result output control signal that obtains among the S6, and described control signal is used to control the tractive force of described transfer membrane stretching and drawing rod, the equal in length in the physical length that makes described version and the described memory edition;
S8: described fixed length stretching machine set composite, gluing on the described transfer membrane after the stretched processing;
S9: described fixed length stretching machine set composite is combined with each other the transfer membrane behind the gluing and paper to send described transfer membrane and described paper in the baking oven then by milling roller again and dries;
S10: described fixed length stretching machine set composite, again basement membrane in the described transfer membrane after compound and described paper are separated, the coating that is loaded with perfect information is stayed on the paper.
Wherein, in the described step of S7, the tractive force of described transfer membrane stretching and drawing rod should be controlled between 2kg~3kg.
Wherein, in the described step of S8, the pressure of described upper glue roller should be controlled between 2kg~3kg.
Wherein, be provided with scraper in a side of described upper glue roller, described scraper is used to control the thickness of gluing.
Wherein, the thickness of described gluing should be controlled between the 4um-5um.
Wherein, in the described step of S9, the pressure of described milling roller should be controlled between 4kg~4.5kg.
Wherein, in the described step of S9, temperature should be controlled between 90 ℃~110 ℃ in the described baking oven.
Wherein, the compound speed of described transfer membrane and described paper should be controlled between the 65-80m/min.
Advantage of the present invention and beneficial effect are: because this technology can be controlled the size between the basement membrane upper plate seam effectively, therefore can improve the product quality of trans-printing and give birth to tea efficient.In addition, this fixed length stretching process using the location, compound, dry, peel off, but succeeding stretch, cover mark, seal mark, dual sensor detect the length manual confirmation between the version seam automatically, stretching is rolled and has been adopted servo-drive multistage stand alone type automatic tension control device, have devices such as the cooling of S type is rolled, zero velocity is overlapped device for mark, line is peeled off in addition, can adapt to water color ink glazing etc., more given prominence to its cost performance, can also reduce percent defective simultaneously, reduce production costs, economized on resources.
