Description

Technical Field

[0001] This invention relates to the field of cold ironing machine manufacturing technology, and in particular to a cold ironing machine's jump ironing mechanism. Background Art

[0002] Currently, common film hot stamping machines are generally equipped with at least two sets of transmission mechanisms. One set of transmission mechanisms is used to transport the film to be hot stamped, and the other set is used to transport the foil material. During operation, the two sets of transmission mechanisms rotate continuously, so that the film and foil material pass between the hot stamping mold and the substrate mold of the hot stamping mechanism. The hot stamping film applies the hot stamping pattern on the foil material to the film, completing 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 to ensure hot stamping efficiency and quality, the spacing between two adjacent hot stamping pattern areas on the foil material needs to be matched with the spacing 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

[0003] In view of the shortcomings of the prior art, the purpose of this invention is to provide a hot stamping mechanism for a cold foil stamping machine that can reduce waste of foil material while ensuring the hot stamping effect.

[0004] The present invention achieves the above objectives as follows:

[0005] This invention discloses a foil-feeding mechanism for a cold foil stamping machine, comprising a foil feeding section, a foil collecting section, and a foil-feeding section connected to a machine base. Foil material passes sequentially through the foil feeding section, the foil-feeding section, and the foil collecting section. The foil-feeding section includes a first mounting base, a first power unit, and a foil-feeding wheel. The first mounting base is connected to the machine base. The first power unit and the foil-feeding wheel are mounted on the first mounting base. The foil-feeding wheel is formed by connecting a connecting wheel and a stamping wheel surface. The stamping wheel surface protrudes from the surface of the connecting wheel. The connecting shaft of the foil-feeding wheel is connected to the output end of the first power unit via a transmission assembly. The stamping wheel surface cooperates with the printing wheel of a film transfer mechanism to achieve hot stamping.

[0006] Furthermore, the hot stamping wheel surface is fixed to the surface of the connecting wheel by screws.

[0007] Furthermore, the transmission assembly includes a first driven wheel, a first belt, and a first driving wheel. One end of the connecting shaft of the hot ironing wheel is fitted with the first driven wheel, the first driving wheel is fitted on the output end of the first power unit, and the first belt is tensioned and connected to the first driven wheel and the first driving wheel.

[0008] Furthermore, the base is equipped with a first guide rail seat and a second guide rail seat. The side of the first guide rail seat and the top surface of the second guide rail seat are both equipped with first guide rails. The first mounting base is provided with a first slider that is slidably connected to the first guide rail.

[0009] Furthermore, the first mounting base is also equipped with a hot ironing wheel position adjustment assembly. The hot ironing wheel position adjustment assembly includes an adjustment guide rail and an adjustment cylinder mounted on the first mounting base, and a mounting frame. The hot ironing wheel and the first power unit are mounted on the mounting frame. The bottom of the mounting frame is provided with an adjustment slider that cooperates with the adjustment guide rail. The mounting frame is connected to the free end of the adjustment cylinder.

[0010] Furthermore, a second guide rail is installed on the top surface and the other side of the first guide rail seat, and a third guide rail is installed on the side and bottom surface of the second guide rail seat.

[0011] Furthermore, the foil feeding section includes a second mounting base, a foil feeding roller mounted on the second mounting base, a plurality of driven foil feeding rollers, and a second power unit. The output end of the second power unit is connected to the foil feeding roller. The second mounting base is provided with a second slider, which is slidably connected to the second guide rail. The second power unit is a magnetic powder brake.

[0012] Furthermore, the foil taking-up section includes a third mounting base, a foil taking-up roller mounted on the third mounting base, a plurality of driven foil taking-up rollers, and a third power unit. The third mounting base is provided with a third slider, which is slidably connected to the third guide rail. A large driven wheel is fixed to one end of the foil taking-up roller, and a small driven wheel is fixed to one end of each of the plurality of driven foil taking-up rollers. A second driving wheel is installed at the output end of the third power unit, and the second driving wheel is connected to the large driving wheel and the small driven wheel via a second belt.

[0013] Furthermore, the foil-laying section also includes an adjustment assembly, which includes an adjustment power unit, a longitudinal guide rail, and an adjustment seat mounted on the second mounting base. The adjustment seat is slidably connected to the longitudinal guide rail, and an adjustment roller is provided on the adjustment seat. The adjustment seat is connected to the adjustment power unit.

[0014] Furthermore, the second mounting base is fixedly connected to the first mounting base by a connecting block and screws, and the first mounting base is fixedly connected to the third mounting base by another connecting block and screws.

[0015] The beneficial effects of this invention are:

[0016] The present invention provides a jumping-heating mechanism for a cold foil stamping machine. The component for applying foil material in the jumping-heating mechanism is designed as a jumping-heating wheel formed by connecting a connecting wheel and a stamping wheel surface, with the stamping wheel surface protruding from the surface of the connecting wheel. When the tensioned foil material passes between the jumping-heating wheel and the printing wheel of the film transfer mechanism, the jumping-heating wheel rotates continuously under the drive of a first power unit, thereby driving the stamping wheel surface to rotate. This allows the stamping wheel surface and the printing wheel to intermittently contact and press against each other intermittently. When the stamping wheel surface and the printing wheel press against each other, the jumping-heating wheel and the printing wheel continue to rotate. Simultaneously, the foil receiving section and the foil releasing section are activated, making the foil material movable. Thus, as the stamping wheel surface and the printing wheel rotate and press against each other, they drive the foil material and the film... The foil is moved forward and the hot stamping pattern on the foil is applied to the corresponding position on the film to achieve the hot stamping operation. When the hot stamping wheel separates from the printing wheel, the foil collection and foil placement sections stop working, making the foil immobile. The hot stamping wheel continues to rotate. Since the surface of the connecting wheel on the hot stamping wheel is lower than the surface of the hot stamping wheel, the connecting wheel cannot contact and press against the printing wheel of the film transfer mechanism. At the same time, the foil collection and foil placement sections stop working, making the foil immobile. Therefore, when the connecting wheel rotates, it cannot drive the foil forward. The foil stops moving. The hot stamping wheel continues to rotate until the hot stamping wheel contacts and presses against the printing wheel again. Then the foil collection and foil placement sections are restarted. Thus, the above operation is repeated until the hot stamping operation on the entire film is completed.

[0017] Since the foil material is only pulled forward when the hot stamping roller and the printing roller work together to perform the hot stamping operation, and remains stationary at other times, the spacing between two adjacent hot stamping pattern areas on the foil material does not need to match the spacing between two adjacent hot stamping positions on the film. The spacing 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 Implementation

[0026] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this invention are only used to explain this invention and are not intended to limit this invention.

[0027] Figures 1-6 The present invention illustrates the specific structure of a hot stamping mechanism in a cold foil press machine. The hot stamping mechanism includes a foil feeding section 1, a foil receiving section 2, and a hot stamping section 3 connected to the machine base. The foil material passes sequentially through the foil feeding section 1, the hot stamping section 3, and the foil receiving section 2. The hot stamping section 3 includes a first mounting base 31, a first power unit 32, and a hot stamping wheel 33. The first mounting base 31 is connected to the machine base. The first power unit 32 and the hot stamping wheel 33 are mounted on the first mounting base 31. The 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 hot stamping wheel 33 is connected to the output end of the first power unit 32 through a transmission assembly. The hot stamping wheel surface 332 cooperates with the printing wheel of the film transfer mechanism to achieve hot stamping.

[0028] The present invention provides a jumping ironing mechanism for a cold foil stamping machine. The component used for stamping foil material in the jumping ironing mechanism is designed as a jumping ironing wheel 333, formed by connecting a connecting wheel 331 and a stamping wheel surface 332. The stamping wheel surface 332 protrudes from the surface of the connecting wheel 331. When the tensioned foil material passes between the jumping ironing wheel 33 and the printing wheel (not shown in the figure) of the film transport mechanism, the jumping ironing wheel 33 rotates continuously under the drive of the first power unit 32, thereby driving the stamping wheel surface 332 to rotate, so that… The hot stamping wheel 332 and the printing wheel can intermittently contact and press against each other multiple times. When the hot stamping wheel 332 presses against the printing wheel, the hot stamping wheel 33 and the printing wheel continue to rotate. At the same time, the foil receiving section 2 and the foil releasing section 1 are activated, so that the foil material is in a movable state. In this way, as the hot stamping wheel 332 and the printing wheel rotate and press against each other, they drive the foil material and the film forward and hot stamping the hot stamping pattern on the foil material onto the corresponding position on the film, thus realizing the hot stamping operation.

[0029] When the hot stamping wheel 332 separates from the printing wheel, the foil receiving section 2 and the foil placing section 1 stop working, leaving the foil material in an immovable state. The hot stamping wheel 33 continues to rotate. Since the surface of the connecting wheel 331 on the hot stamping wheel 33 is lower than the surface of the hot stamping wheel 332, the connecting wheel 331 cannot contact and press against the printing wheel of the film transfer mechanism. At the same time, the foil receiving section 2 and the foil placing section 1 stop working, and the foil material is in an immovable state. Therefore, when the connecting wheel 331 rotates, it cannot drive the foil material forward. The foil material stops moving, and the hot stamping wheel 33 continues to rotate until the hot stamping wheel 332 contacts and presses against the printing wheel again. Then, the foil receiving section 2 and the foil placing section 1 are restarted to realize the hot stamping operation. Thus, the above operation is repeated until the hot stamping operation of the entire film is completed.

[0030] Since the foil material is only pulled forward when the hot stamping roller 332 and the printing roller cooperate to perform the hot stamping operation, and remains stationary at other times, the spacing between two adjacent hot stamping pattern areas on the foil material does not need to be adapted to the spacing between two adjacent hot stamping positions on the film. The spacing 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, ensuring the hot stamping effect, and further reducing the energy consumption of the cold stamping machine since the foil material does not need to rotate continuously.

[0031] Furthermore, in this embodiment, as Figure 3 and Figure 6 As shown, the hot stamping wheel surface 332 is fixed to the surface of the connecting wheel 331 by screws, which facilitates disassembly for maintenance or replacement with hot stamping wheel surfaces of different sizes to meet different hot stamping requirements; in other embodiments, the hot stamping wheel 33 can be formed by connecting the connecting wheel 331 and the hot stamping wheel surface 332 as one piece, with the hot stamping wheel surface 332 protruding from the surface of the connecting wheel 331.

[0032] Furthermore, in this embodiment, as Figure 3 , Figure 5 , Figure 6 As shown, the transmission assembly includes a first driven wheel 341, a first belt 342, and a first driving wheel.

The first belt 342 is stretched and connected to the first driven wheel 341 and the first driving wheel.

[0033] Furthermore, in this embodiment, as Figure 1 and Figure 5 As shown, the base is equipped with a first guide rail seat 4 and a second guide rail seat 5. The side of the first guide rail seat 4 and the top surface of the second guide rail seat 5 are both equipped with a first guide rail 6. The first mounting base 31 is provided with a first slider 311 that is slidably connected to the first guide rail 6.

[0034] Furthermore, in this embodiment, as Figure 3 As shown, the first mounting base 31 is also equipped with a jump ironing wheel position adjustment assembly. The jump ironing wheel position adjustment assembly includes an adjustment guide rail 312 and an adjustment cylinder 313 mounted on the first mounting base 31, and a mounting frame 314. The jump ironing wheel 33 and the first power unit 31 are mounted on the mounting frame 314. The bottom of the mounting frame 314 is provided with an adjustment slider 315 that cooperates with the adjustment guide rail 312. The mounting frame 314 is connected to the free end of the adjustment cylinder 313. The adjustment cylinder 313 drives the mounting frame 314 to slide along the adjustment guide rail 312 to adjust the distance between the jump ironing wheel 33 and the foil receiving part 2 and the foil releasing part 1.

[0035] Furthermore, in this embodiment, as Figure 4 As shown, a second guide rail 7 is also installed on the top surface and the other side of the first guide rail seat 4, and a third guide rail 8 is also installed on the side and bottom surface of the second guide rail seat 5.

[0036] Furthermore, in this embodiment, as Figure 1 , Figure 2 and Figure 4 As shown, the foil feeding section 1 includes a second mounting base 11, a foil feeding roller 12 mounted on the second mounting base 11, a plurality of driven foil feeding rollers 13, and a second power unit 14.

The second slider 111 is slidably connected to the second guide rail 7. The second power unit is a magnetic powder brake.

[0037] Furthermore, in this embodiment, as Figure 4, Figure 5 Figure 6 As shown, the foil taking-up section 2 includes a third mounting base 21, a foil taking-up roller 22 mounted on the third mounting base 21, a plurality of driven foil taking-up rollers 23, and a third power unit 24.

One end of the foil taking-up roller 22 is fixed with a large driven wheel 221, and one end of the plurality of driven foil taking-up rollers 23 is fixed with a small driven wheel 231. The output end of the third power unit 24 is equipped with a second driving wheel, and the second driving wheel is connected to the large driving wheel 221 and the small driven wheel 231 by a second belt 25.

[0038] Furthermore, in this embodiment, as Figure 1 As shown, the foil feeding section 1 further includes an adjustment assembly. The adjustment assembly includes an adjustment power unit (not shown in the figure), a longitudinal guide rail 15, and an adjustment seat 16, all mounted on the second mounting base 11. The adjustment seat 16 is slidably connected to the longitudinal guide rail 15. An adjustment roller 161 is provided on the adjustment seat 16. The adjustment seat 16 is connected to the adjustment power unit. The adjustment power unit drives the adjustment seat 16 to move up and down along the longitudinal guide rail 15 to adjust the position of the adjustment roller 161 and adjust the tension of the foil material.
