[0002] Currently common film hot stamping machines are generally equipped with at least two sets of transmission mechanisms, one of which is used to transport the film to be hot stamped, and the other is used to transport foil materials. During operation, the two sets of transmission mechanisms rotate continuously, so that the film and foil materials pass between the hot stamping mold and the printing mold of the hot stamping mechanism, and the hot stamping pattern on the foil material is hot-stamped onto the film by the hot stamping film to complete the hot stamping operation. In order to make the hot stamping pattern on the foil material correspond to the hot stamping position on the film and ensure the hot stamping efficiency and hot stamping quality, the distance between two adjacent hot stamping pattern areas on the foil material needs to be adapted to the distance between two adjacent hot stamping positions on the film. However, in this way, the material between the two hot stamping pattern areas on the foil material will be wasted, and it is difficult to further reduce the cost. Summary of the invention

The first driven wheel is mounted on one end of the connecting shaft of the jumping iron wheel. The first driving wheel is mounted on the output end of the first power device.

At the same time, the foil collecting part and the foil releasing part are also started to make the foil and film materials in a movable state. In this way, the hot stamping wheel surface and the printing wheel drive the foil and film materials and the film in the process of rotating and pressing against each other. The foil material is immovable when the hot stamping wheel is in contact with the printing wheel and the foil collecting and releasing parts stop working. Since the foil material is only pulled forward when the hot stamping wheel surface and the printing wheel cooperate with each other to implement the hot stamping operation, and stops at other times, the distance between two adjacent hot stamping pattern areas on the foil material does not need to be matched with the distance between two adjacent hot stamping positions on the film. The distance between two adjacent hot stamping pattern areas on the foil material can be further reduced, thereby making full use of the foil material, reducing material waste, and ensuring the hot stamping effect.

DETAILED DESCRIPTION

[0017] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with examples and drawings. The schematic implementation scheme of the present invention and its description are only used to analyze the present invention and are not intended to limit the present invention.

[0018] Figure 1-Figure 6 The specific structure of a jump hot stamping mechanism of a cold stamping machine of the present invention is shown, the jump hot stamping mechanism includes a foil placing part 1, a foil collecting part 2, and a jump hot stamping part 3 connected to a machine base, the foil film material passes through the foil placing part 1, the jump hot stamping part 3, and the foil collecting part 2 in sequence, the jump hot stamping part 3 includes a first mounting seat 31, a first power device 32, and a jump hot stamping wheel 33, the first mounting seat 31 is connected to the machine base, the first power device 32 and the jump hot stamping wheel 33 are installed on the first mounting seat 31, wherein the jump hot stamping wheel 33 is formed by connecting a connecting wheel 331 and a hot stamping wheel surface 332, the hot stamping wheel surface 332 protrudes from the surface of the connecting wheel 331, the connecting shaft 333 of the jump hot stamping wheel 33 is connected to the output end of the first power device 32 through a transmission assembly, and the hot stamping wheel surface 332 cooperates with the printing wheel of the film transmission mechanism to achieve hot stamping.

[0019] The present invention provides a jump ironing mechanism of a cold foil stamping machine. The jump ironing mechanism is designed as a jump ironing wheel 333 formed by connecting a connecting wheel 331 and a stamping wheel surface 332, and the stamping wheel surface 332 is made to protrude from the surface of the connecting wheel 331. When the tensioned foil material passes between the jump ironing wheel 33 and the printing wheel (not shown in the figure) of the film transmission mechanism, the jump ironing wheel 33 is driven by the first power device 32 to rotate continuously, so as to drive the stamping wheel surface 332 to rotate, so that the tensioned foil material passes between the jump ironing wheel 33 and the printing wheel (not shown in the figure) of the film transmission mechanism. The hot stamping wheel surface 332 and the printing wheel can intermittently contact and press against each other for multiple times. When the hot stamping wheel surface 332 and the printing wheel are pressed against each other, the hot stamping wheel 33 and the printing wheel are continuously driven to rotate. At the same time, the foil collecting part 2 and the foil releasing part 1 are also started to work, so that the foil film material is in a movable state. In this way, the hot stamping wheel surface 332 and the printing wheel are driven to move forward in the process of rotating and pressing against each other, and the hot stamping pattern on the foil film material is hot-stamped to the corresponding position of the film, so as to realize the hot stamping operation. When the stamping wheel surface 332 is separated from the printing wheel, the foil collecting part 2 and the foil placing part 1 stop working, so that the foil film material is in an immovable state, and the jumping stamping wheel 33 is continuously driven to rotate. Since the surface of the connecting wheel 331 on the jumping stamping wheel 33 is lower than the surface of the stamping wheel surface 332, the connecting wheel 331 cannot contact and press against the printing wheel of the film transmission mechanism. At the same time, the foil collecting part 2 and the foil placing part 1 stop working, and the foil film material is in an immovable state. Therefore, when the connecting wheel 331 rotates, it cannot drive the foil film material to move forward. The foil film material stops moving, and the jumping stamping wheel 33 is continuously driven to rotate until the stamping wheel surface 332 contacts and mortgages the printing wheel again and the foil collecting part 2 and the foil placing part 1 are started again to realize the hot stamping operation. Thus, the above operation is repeated until the hot stamping operation of the entire film is completed. Since the foil material is only pulled forward when the stamping wheel surface 332 cooperates with the printing wheel to implement the hot stamping operation, and stops at other times, the distance between two adjacent hot stamping pattern areas on the foil material does not need to be adapted to the distance between two adjacent hot stamping positions on the film. The distance between adjacent hot stamping pattern areas on the foil material can be further reduced, thereby making full use of the foil material, reducing material waste, and ensuring the hot stamping effect. Moreover, since the foil material does not need to rotate continuously, the energy consumption of the cold stamping machine can be further reduced.
