Multi-station mould pressing machine
Technical field
The present invention relates to a kind of moulding press, belong to the anti-counterfeit laser technical field.
Background technology
The laser stamping systems, the radium-shine The Application of Technology demands of holographic false proof such as environment-friendly laser transfer paper increase gradually, in order to satisfy the demand, just need to improve the efficient of laser molding imaging technique.Traditional laser molding becomes camera; comprise main body; electrical control gear; Scroll; tensioner and mold pressing mechanism; electrical control gear is controlled the electric part of main frame; Scroll is arranged on head end and puts film; tensioner is the film tensioning; carry out mold pressing by mold pressing mechanism, existing mold pressing mechanism is single edition mold pressing, like this; if mold pressing version group goes wrong; it is long to change the mold pressing version group time, causes downtime long, seriously lowers production efficiency; in addition; because often there are the quality problems of keeping away seam and transferring seam in the mold pressing of single roller list warm area, causes product substandard products proportion of goods damageds height.
Summary of the invention
At prior art existing problems, the objective of the invention is to overcome above-mentioned shortcoming, providing a kind of can lower downtime, enhance productivity and multi-station mould pressing machine.
The present invention solves the technical scheme that its technical problem takes: a kind of multi-station mould pressing machine, it comprises main body, electrical control gear, Scroll, tensioner and mold pressing mechanism, it is characterized in that: described mold pressing mechanism comprises the mold pressing version group and the switching mechanism of two stations, the mold pressing version group of described each station comprises an edition roller, silica gel mold pressing roll and chill roll respectively, and described switching mechanism is changed the mold pressing version group of two stations.
Multi-station mould pressing machine, described mold pressing mechanism is two groups, and two groups of mold pressings are respectively low temperature mold pressing district and hot press moulding district, and described low temperature mold pressing district and hot press moulding mechanism are provided with in proper order.
Described multi-station mould pressing machine, described tensioner are two automatic tension controllers, and it is separately positioned on the two ends of two groups of mold pressing mechanisms.
Described multi-station mould pressing machine is respectively equipped with carry-over pinch rolls in the front portion of every group of mold pressing mechanism.
The present invention is owing to be provided with the mold pressing version group and the switching mechanism of two stations, when in use, when the mold pressing version group of a station is damaged, can directly mold pressing version group be changed into the mold pressing version group of another one station by switching mechanism, thereby reduce downtime, enhance productivity; In addition because mold pressing mechanism is set to two groups, two groups of mold pressings are respectively low temperature mold pressing mechanism and hot press moulding mechanism, described low temperature mold pressing mechanism and hot press moulding mechanism are provided with in proper order, after through the version seam process hot press moulding mechanism after the mold pressing for the first time, disappear like this, thereby improved product quality.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
Multiple station die press of the present invention, comprise main body, electrical control gear, Scroll, tensioner and mold pressing mechanism, tensioner is the automatic tension controller, as shown in Figure 1, mold pressing mechanism is two groups, two groups of mold pressing mechanisms are provided with in proper order, be provided with A station mold pressing version group and B station mold pressing version group in first group, this A station mold pressing version group comprises front page roller 2, silica gel mold pressing roll 3 and chill roll 4, B station mold pressing version group comprises second edition roller 5, the second silica gel pressure roller 6 and second chill roll 7 also are provided with the mechanism that A station mold pressing version group and B station mold pressing version group are changed mutually in first group of mold pressing mechanism;
Be provided with C station mold pressing version group and D station mold pressing version group in second group of mold pressing mechanism, C station mold pressing version group comprises front page roller 8, silica gel mold pressing roll 9 and chill roll 10, D station mold pressing version group comprises second edition roller 11, the second silica gel pressure roller 12 and second chill roll 13, is respectively equipped with carry-over pinch rolls 15,16 in first group of mold pressing mechanism and second group of mold pressing mechanism.
The course of work is: the base film that will need mold pressing passes (unreeling by the control of magnetic tensioner) in unreeling shaft 1 and passes automatic tension controller 17 and regulate the leading portion tension force.Enter first group of A station mold pressing version group through carry-over pinch rolls 15 live-rollers, film goes out the first mold pressing mechanism and has promptly produced laser effect.Enter second group of C station mold pressing version group again, the front page version is sewn on the overlapping mold pressing in high-temperature region of second edition, front page disappears after being sewn on overlapping mold pressing, second edition version seam is in the low-temperature space of second roller, not producing the mold pressing effect and kept the molding laser effect of front page, has been seamless effect on the basement membrane when going out the second mold pressing mechanism, through automatic tension controller 18, rolling then, this moment, the no-slot laser molding product was finished.When producing, when causing quality on the mold pressing version group defective because of foul or other reasons, can by B station mold pressing version group replace A station mold pressing version group as occurring in first group this moment, same as occurring in the second level, then can be by D station mold pressing version group replaced C station mold pressing version group.
