Multi-station rotary hot-stamping machine with functions of synchronous change and automatic marking of aluminized foil rolls

Abstract

The invention provides a multi-station rotary hot-stamping machine with functions of synchronous change and automatic marking of aluminized foil rolls. The machine comprises one or more synchronous roll changing mechanisms (1) and delayed starters (2); each synchronous roll changing mechanism (1) is composed of pay-off devices (11), a pre-fixing device (12) for a roll to be changed, a wallboard (130 and a delayed cutter (14). The machine further comprises an automatic marking mechanism (3) and a master controller (4). The synchronous roll changing mechanisms (1) are disposed on an aluminized foil hot-stamping station; the automatic marking mechanism (3) is disposed on a substrate winding station (6); the delayed starters (2) are disposed among the mechanisms and are connected with the master controller (4). By controlling multiple aluminized foil rolls different in color respectively in the rotary hot-stamping process, the machine allows the aluminized foil rolls in multiple colors to be automatically changed, allows the aluminized foil rolls identical in color to be synchronously changed and allows joints to be automatically marked, thus the joints are easily removed during rewinding.

Description

technical field [0001] The invention relates to an auxiliary equipment for circular pressing and hot stamping, in particular to an automatic synchronous roll changing and marking device for anodized aluminum. Background technique [0002] In the process of circular hot stamping, it is necessary to transfer the material on the anodized aluminum film to the substrate paper. Due to the different lengths of the paper and the anodized aluminum film, the anodized aluminum needs to be replaced during the hot stamping process. The existing hot stamping When the equipment runs out of anodized aluminum, it can only be replaced by a new coil. For hot stamping equipment running at high speed, the shutdown will bring many adverse consequences: the shutdown will affect the continuity of the bronzing operation, especially in the process of multiple When hot-stamping rolls of anodized aluminum, it is necessary to replace one by one with multiple rolls of anodized aluminum, which takes longe...

Problems solved by technology

[0007]First of all, when the device fixes the position to be changed in advance, it is realized by the adsorption device, and it needs to use specific rollers to complete the docking, and each part has a single function 1. The integration of the equipment is low, and the parts occupy a large position in the hot stamping equipment; secondly, the device is not equipped with a cutting device that can act synchronously or with a delay corresponding to the docking action, and needs to be cut separately, which will affect the single roll hot stamping operation. Not big, but when performing multi-volume hot stamping, the position of the joints of each roll of hot stamping products will be quite different, which is not conducive to the inspection of the joints during the subsequent rewinding operation, and it is easy to cause missed inspections of the joints and cause serious product quality. In addition, the device did not take into account that under the condition of high-speed operation of bronzing equipment, the docking operation cannot be 100% successful at one time, and it did not set up corresponding remedial measures. Therefore, the stability and reliability of the equipment in the comparison document are relatively low. Low
