The invention provides an air bearing foil stamping auxiliary device. Each pressing plate is fixedly provided with a display spring guide column. Each display spring guide column is sleeved with a display spring. Guide holes of the stamping plate penetrate through the upper ends of the corresponding display spring guide columns and are pressed on the display springs; the stamping plate limiting piece limits the height position of the stamping plate; the upper die assembly is arranged on the lower die and matched with the lower die to form a stamping model. The blank holder force intelligent control assembly collects the pressure of each display bullet on the pressing plate, and when the sum of the pressure is larger than or equal to the set standard punching force, the punching force is stopped from being increased; and when the sum of the pressure is smaller than the set standard stamping force, the stamping force is stopped from being increased. The stamping die has the advantages that main body stamping and edge pressing force of four edges are achieved at the same time through one stamping force, and the edge pressing force can be accurately controlled; and the rebound rate of the foil after punch forming is reduced, the uniform wave height is ensured, and the manufacturing requirement of the air bearing foil is met.

The present invention relates to a foil stamping die used for foil stamping, and a method of manufacturing a vehicle interior component using the foil stamping die. An object of the present invention is to provide a foil stamping technique capable of enhancing the design property of a printing object. In a foil stamping die capable of transferring a foil to the printing object while applying an uneven pattern to a surface of the printing object by pressing the die toward the printing object on which the foil is placed, a pattern-shape portion which is a portion corresponding to the uneven pattern is provided, and an edge of the pattern-shape portion has the same thickness over the entire area thereof.

This utility model discloses a full-rotation / intermittent printing equipment with a skip-step cold foil stamping device, including a winding device and an unwinding device. A substrate transport path is formed between the winding device and the unwinding device. A skip-step cold foil stamping device is provided on the substrate transport path. The skip-step cold foil stamping device includes a cold foil film winding mechanism, a cold foil film unwinding mechanism, and a pressure roller. The pressure roller is disposed between the cold foil film unwinding mechanism and the cold foil film winding mechanism. The pressure roller presses the cold foil film onto the substrate. The pressure roller is connected to a lifting drive mechanism that drives it to lift and press down. After each hot foil stamping operation on the substrate, the pressure roller is lifted by the lifting drive mechanism to allow the cold foil film to retract. The cold foil film retracts to a set length and then stops. The pressure roller then descends to continue pressing the cold foil film onto the next substrate. The pressure roller of the present invention moves upward to allow the cold foil to retract, so that the cold foil retracts to a set length, making the hot stamping pattern on the cold foil compactly arranged with the prior pattern, thereby improving the utilization rate of the cold foil and effectively controlling costs.

This utility model relates to the technical field of printing equipment, and in particular to a cold foil transfer printing device for pharmaceutical packaging. It improves transfer quality by using an adaptively movable and height-adjustable roller to prevent excessive stretching and deformation of the transfer film. The device includes a base plate and a fixed roller, with the fixed roller rotatably mounted on the left end of the base plate. It also includes a slide table, a movable roller frame, two vertical sliding grooves, a roller shaft, a movable roller, and a reciprocating mechanism. The slide table is slidably mounted on a slide rail on the base plate via a slider. The movable roller frame is height-adjustable and mounted on the slide table. Vertical sliding grooves are provided at both ends of the movable roller frame. The roller shaft is slidably mounted in the two vertical sliding grooves at both ends. The movable roller is rotatably mounted on the roller shaft. The reciprocating mechanism is mounted on the base plate and drives the slide table to move back and forth on the base plate.
