Laser imprint transfer equipment is mainly divided into two categories: one is a dedicated laser imprint transfer production line; the other is a separate laser imprint transfer unit. The common component of these two types of equipment is the imprint transfer unit (shown in Figure 1), which is mainly composed of a laser imprint transfer film take-up and take-up mechanism, an imprint transfer mechanism, and a UV curing system. 
The laser imprint transfer film rewinding and unwinding mechanism mainly consists of an air expansion shaft, a magnetic powder brake (or a variable frequency motor, a servo motor), a paper feed roller, a damper roller, a pressure sensor, a tension sensor, a static eliminator, and a film aligning device. composition. At present, there are three main types of laser embossed transfer film rewinding and unwinding mechanisms on the market.
(1) One-way retracting and unwinding mechanism
Each time the agency replaces the laser-imprinted transfer film, it is necessary to manually use the boom to transfer the laser-imprinted transfer film from the take-up reel to the take-up reel.
(2) Two-way retracting and unwinding mechanism
The whole body can be rotated, the unwinding frame and the winding frame are installed on the same platform, and the manipulator, the cylinder and the like are installed under the platform, and the reel and the reel are connected with the driving motor by pneumatic interlocking, and the reel is controlled by the program when changing the reel. The drive motor is unlocked, the platform is lifted and rotated by 180°, the original reel A is connected with the original winding drive motor B, and the original reel B is connected with the original winding drive motor A, and the film is manually connected to complete the roll change.
(3) Retracting and unwinding mechanism with bidirectional driving function
The mechanism can be quickly rewinded. Its main feature is that the laser embossed transfer film roll can be normally retracted and released during the imprint transfer. When the laser embossed transfer film is unwinded, the device stops immediately and the laser embossing at the winding position The transfer film is quickly rewinded until it is rewinded and then printed normally. The rewinding speed can reach 200m/min or more, and the rewinding reel can be rolled up in a few minutes without switching back and forth.
