Problems solved by technology

However, if the anodized aluminum used for the first time is randomly curled during the winding process, it will be difficult to perform secondary hot stamping on it. Generally, the anodized aluminum used once in this case will be discarded, which will cause a lot of waste of resources.

Abstract

The invention discloses a device for carrying out hot stamping for multiple times on one impression roller. One impression unit comprises an impression roller (6) and a plurality of hot-stamping rollers at least comprising a front hot-stamping roller (3) and a rear hot-stamping roller (1), wherein a plurality of hot-stamping rollers are subjected to impression and hot stamping by virtue of one impression roller (6); an ultrasonic microscale humidifying device (10) is arranged behind the hot-stamping rollers; and each hot-stamping roller comprises a roller core (11) and a heat conduction layer (12) arranged at the periphery of the roller core. The device disclosed by the invention can implement different alumite hot stamping processes one each hot-stamping roller, thus the bottleneck of a single hot-stamping roller is broken through, the hot stamping efficiency is greatly improved and the floor area is reduced, and the cost is reduced while the hot-stamping overprinting precision is improved; and the device also can implement the same alumite hot stamping process by adopting two or a plurality of hot-stamping rollers, so that the spare area on the stamped alumite can be beneficially utilized, and the service efficiency of the alumite is effectively improved.

Description

technical field [0001] The invention relates to a printing machine, in particular to a device for multiple hot stamping on the same embossing roller. Background technique [0002] Anodized aluminum hot stamping is the method of heating and applying pressure to transfer the pattern or text to be hot stamped to the surface of the material to be hot stamped. In our country, anodized aluminum hot stamping has become an indispensable surface decoration method for modern packaging. In general packaging printing, there is a situation that one or more kinds of anodized aluminum foil stamping is required on one package surface. The current technical situation is that the stamping operation is performed sequentially in the form of an assembly line. Each stamping pattern of anodized aluminum needs to be stamped by one unit. process, the disadvantage is that the accuracy of hot stamping overprinting is poor, the equipment cost is high, the space is large, and it takes a long time. Since...
