After searching, it was found that the Chinese patent with the announcement number CN216733581U disclosed a production device for accurately positioning printed hot stamping transfer film. In this patent, the connection seat is driven to rise by an electric telescopic rod, so that the spraying seat is away from the fixed seat, and the fixed seat is connected to the negative pressure device through the air pipe, and the substrate is fixed on the fixed seat by the negative pressure generated by the adsorption hole; when spraying, the connection seat is driven down by the electric telescopic rod, and then the spraying seat on the connection seat is driven down, and the switch of the motor is turned on.
