Embodiment 1

[0027]As shown in Figure 1, Figure 2, and Figure 3, the laser holographic molding machine includes a frame 1, on which the first molding station and the second molding upper position are installed, and the first molding station is provided with a plate roller 21. The second molding station is equipped with a version roller 22, and a thermal oil internal circulation heating device is installed in the version roller; each molding station is provided with a backing roller 3, a pressing roller 4, and an oil cylinder 5, and the pressing roller 4 is provided with a Cooling water circulation cooling device, the lining roller 3 is a rubber roller, the rubber roller 3 is installed between the version roller 2 and the pressure roller 4, the two ends of the version roller are fixed on the frame, and the left and right sides of the frame are respectively equipped with Horizontal guide rail 6, slide plate 7 is installed respectively on the horizontal guide rail 6 of both sides, as shown in ...

Embodiment 2

[0033] The laser holographic molding process shown in Fig. 1 adopts the laser holographic molding machine described in Embodiment 1, comprising the following steps:

[0034] a. The molding manufacturer rolls and pastes the metal mold embossing plate 10 with the same laser dot matrix grating graphic information on the first plate roller 21 and the second plate roller 22 respectively, and the first plate roller forms a seam A of the metal mold embossing plate; A seam B of the metal mold embossing plate is formed on the second version roller; the seam B of the metal mold embossing plate on the second edition roller is aligned with the position of the cooling water flow channel, such as Figure 5 , Figure 6 shown;

[0035] b. Circularly transport hot oil to the first version roller through the hot oil pipeline, control the surface temperature of the first version roller at about 145°C, and carry out laser holographic embossing on the plastic film 13 at the first molding station. ...

Abstract

The laser hologram molding press includes one first molding site with one first plate roller with circular heating pipeline, one pressure roller and one lining roller in between; and one second molding site with one second plate roller with circular heating pipeline and one outer cooling water flow channel, one pressure roller and one lining roller in between. Each of the first molding site and the second molding site has one photoelectric eye for monitoring the joint of the molding metal plate, and the motor in the second plate roller has one rotation speed controlling circuit. The present invention has relatively low plate roller operation temperature and can eliminate plate gap in laser hologram molded film product. The present invention also provides laser hologram molding process.

Description

technical field [0001] The invention belongs to a laser holographic molding machine for producing laser holographic molding film products and a laser holographic molding process. Background technique [0002] The traditional laser holographic molding machine adopts single-roller one-time embossing technology. It only sets one molding station between the unwinding device and the winding device. Sandwiched between the version roller and the pressure roller, the version roller is equipped with a circulating heating oil pipeline, and the pressure roller is equipped with a cooling device. On the horizontal guide rail, the pressure roller can be pressed against the backing roller, and the backing roller can be pressed against the plate roller; the pushing mechanism is connected to the supports at both ends of the pressure roller, and the pushing mechanism generally adopts an oil cylinder. Before the embossing starts, the metal molded plate with laser holographic pattern pre-etche...
