Abstract

The utility model discloses a laser molding press capable of reducing the start-up loss. The laser molding press comprises a main body, an electrical control device, a retractable reel, a tension device, a traction device, and a molding pressing device, wherein the molding pressing device comprises two groups, and each group of the molding pressing devices comprises one printing roller and two groups of cooling pressure groups. In the starting process, in the first group of the molding pressing devices, the first cooling pressure group through which no base film passes is tightly close to the first printing roller, and when the parameters such as temperature are stable, the first cooling pressure group is away from the first printing roller, and immediately the second cooling pressure group through which a base film passes is tightly close to the first printing roller in the first group of the molding pressing device (in the whole starting process, the second group of the molding pressing devices and the first group of the molding pressing devices running in phase), so that the base film is subjected to molding pressing when the parameters such as the temperature are stable, so as to reduce the start-up loss and the production cost.

A kind of laser molding press that reduces starting loss

Technical field

The utility model relates to a kind of laser molding press that reduces starting loss, belongs to laser holography anti-counterfeit internal technical field.

Background technology

The application supply and demand of the radium-shine technology of holographic false proof such as laser hot stamping, laser transfer membrane, laser composite film are increasing, traditional radium-shine imaging moulding press is all wanted some basement membranes of loss when mold pressing starts, to reach stable mold pressing effect, particularly thereby radium-shine seamless mold pressing starting is wanted the film of loss 300-500 rice just can reach isoparametric the stablizing of temperature to reach stable mold pressing effect, and its mold pressing yield rate can only reach 95% left and right.If run into its yield rate 90% of cancel closedown less than, cause a lot of wastes and production cost improved greatly.

Utility model content

The utility model has overcome the problem for above-mentioned existence, provides a kind of and can reduce the laser molding press that starting loss improves yield rate.

The technical solution of the utility model:

A laser molding press that reduces starting loss, comprising: main body, electrical control gear, folding and unfolding spool, tensioner, draw-gear, molding device, and described molding device comprises two groups, described two groups of molding devices arrange in order; First group of molding device comprises the first roller, the first silica gel roller, the first chill roll, the second silica gel roller, the second chill roll, and second group of molding device comprises the second roller, the 3rd silica gel roller, the 3rd chill roll, the 4th silica gel roller, the 4th chill roll; The first silica gel roller and the first chill roll form the first cooling pressure group, the second silica gel roller and the second chill roll form the second cooling pressure group, the 3rd silica gel roller and the 3rd chill roll form the 3rd cooling pressure group, the 4th silica gel roller and the 4th chill roll form the 4th cooling pressure group, described the first cooling pressure group can be synchronizeed and be close to or leave the first roller and the second roller in molding device with the 4th cooling pressure group, and the second cooling pressure group can be synchronizeed and be close to or leave the first roller and the second roller in molding device with the 3rd cooling pressure group.

The utility model will only be furnished with roller in every group of traditional molding device, silica gel roller, each of chill roll, change into and in every group of molding device, be furnished with one of roller, two of silica gel rollers, two of chill rolls, in starting-up process, in first group of molding device, first use without basement membrane and be close to through the first cooling pressure group and the first roller, when reaching the first cooling pressure group and the first roller while stablizing, the parameters such as temperature leave, after leaving, by there being basement membrane to pass the second cooling pressure group in first group of molding device, be close to (second group of molding device of whole starting-up process and first group of molding device carry out for synchronizeing) with the first roller at once, in the situation that reaching stable, the parameters such as temperature just start like this mold pressing basement membrane, thereby reach, reduce the effect that start loss reduces production costs.
