Abstract

The utility model provides a holographic electrochemical aluminium semi-automatic registration device of circle pressure circle gilding press, installs before holographic thermoprint electrochemical aluminium feed mechanism, on the colour group supporting rod of electrochemical aluminium transport position, mainly by parts such as worm gear 11, two gyro wheels 15, rocking disc 13 and gyro wheel pendulum rod 14 installed on base 12 constitute, use the device can realize that high-speed holographic thermoprint is timely, effectual registration is rectified, greatly improves production efficiency, reduces the consumption.

Description

The semi-automatic registration device of the holographic electrochemical aluminium of rotary-cutting hot stamping machine

Affiliated field: the utility model relates to the printing equipment technical field.

Background technology: existing gold stamping equipment, as shown in Figure 1, comprise that electrochemical aluminium closed reel 1, electrochemical aluminium deflector roll 2, swing-bar mechanism 3, electrochemical aluminium feed roller 4, electrochemical aluminium unreel the electrochemical aluminium unwinding and rewinding feed mechanism that dish 7 is formed, and photoelectric sensor 5, the 10 electrochemical aluminium register control mechanisms that form, impression that stock deflector roll 8, printing plate 9 are formed and heating arrangements etc. are partly.Its operation principle is: when the thermoprint holographic anti-counterfeiting label, photoelectric sensor 5 provides the position of contained hologram pattern on the electrochemical aluminium 6, controls electrochemical aluminium feeding speed ω by computer in good time ₂Reach synchronous with the printing plate position.When hot stamping pattern was passed through printing plate 9, the master control computer made printing plate external circe speed ω ₁, substrate speed v and electrochemical aluminium film translational speed all reach synchronous consistent, simultaneously contained hologram pattern also reaches synchronous consistent on thermoprint position on printing plate pattern and the stock and the electrochemical aluminium 6, under high temperature printing plate and force of impression P effect, the electrification aluminium film and on hologram pattern transfer to the stock surface, finish holographic thermoprinted.By controlling the speed omega of electrochemical aluminium closed reel 1 ₃For electrochemical aluminium provides tension force.

But in use, the master control computer often occurs crashing owing to be subjected to the hot stamping equipment Temperature Influence, causes hologram pattern to transfer to the malposition on the stock, holographic alignment can't be rectified a deviation; During each the start, hologram pattern on the electrochemical aluminum dipping form and the thermoprint location dislocation on the stock are bigger, and it is consuming time too many to depend merely on the computer correction, cause production efficiency to reduce, consume rising; In addition, equipment is influenced by various factors in operation process, causes the hologram pattern position on the electrochemical aluminum dipping form often to change, and computer just can't be rectified a deviation when excursion was excessive; Also can cause computer crash maybe can't rectify a deviation and touch master control computation screen continually, the inaccurate waste product of a large amount of thermoprints occur.

Summary of the invention: at the deficiency of above-mentioned existence, the utility model proposes the semi-automatic registration device of the holographic electrochemical aluminium of a kind of rotary-cutting hot stamping machine, use this device can realize timely, the effectively alignment correction of gold breath thermoprint at a high speed, greatly improved production efficiency, reduce consuming.

Description of drawings: Fig. 1 is existing rotary-cutting hot stamping principle of device schematic diagram.

Fig. 2 is the principle schematic according to the semi-automatic registration device of the holographic electrochemical aluminium of the rotary-cutting hot stamping machine that the utility model proposes.

Fig. 3 is that the A of alignment governor motion among Fig. 2 is to partial schematic diagram.

As Fig. 2,3 show, the semi-automatic registration device of the holographic electrochemical aluminium of rotary-cutting hot stamping machine, comprise by electrochemical aluminium closed reel 1, electrochemical aluminium deflector roll 2, swing-bar mechanism 3, electrochemical aluminium feed roller 4, electrochemical aluminium and unreel the dish 7 electrochemical aluminium unwinding and rewinding feed mechanisms of forming, and photoelectric sensor 5, the 10 electrochemical aluminium register control mechanisms that form, impression that stock deflector roll 8, printing plate 9 are formed and heating arrangements etc. are partly.Before the utility model is installed in the holographic thermoprinted electrochemical aluminium feed mechanism of original rotary-cutting hot stamping device, on the colour cell cramp bar of electrochemical aluminium transfer position, mainly constitute by the parts such as worm and gear 11, two roller 15, shaking tray 13 and roller fork 14 that are installed on the base 12.Manually shaking tray links to each other with worm shaft, outwards is connected with roller fork 14 on the worm-wheel shaft, and the fork two ends respectively have a roller to constitute two idler wheel mechanisms.

Electrification aluminium 6 is walked around two rollers 15 earlier, is carried out thermoprint through electrochemical aluminium deflector roll 2 to printing plate 9 again.The roller fork can suitable, counter-clockwise swing, and adjustable range is bigger, and when shaking tray 13 turned clockwise, the engaged transmission by worm gear and worm screw drove the fork that is connected on the worm gear and also turns clockwise, and moves backward by the roller pulling again; Otherwise when shaking tray was rotated counterclockwise, electrochemical aluminium moved forward.Occurring electrochemical aluminium thermoprinting in start or thermoprint process can not use this device to carry out the alignment correction on time, hologram pattern, the hot stamping pattern on the printing plate and the thermoprint position three on the stock on the electrochemical aluminium film are consistent, carry out the locating thermoprint of hologram pattern.Worm screw, worm-drive have self-locking performance in addition, when electrochemical aluminium is adjusted to the tram, can guarantee the relative stability of correct thermoprint position; When occurring the thermoprint position deviation once more, regulate this device and can realize accurate thermoprint again.
