Description

Technical Field

[0001] This utility model belongs to the field of double-sided hot stamping, and specifically relates to a double-sided hot stamping device. Background Technology

[0002] Hot stamping, also known as foil stamping, is a printing decoration process that involves heating a metal printing plate to apply foil, pressing gold lettering or patterns onto a printed label. Existing hot stamping equipment typically includes a conveyor belt for transporting the printed label paper and a hot stamping pressing plate positioned above the conveyor belt, with the hot stamping foil placed on the top surface of the printed label paper.

[0003] Existing technologies have developed some double-sided hot stamping devices. For example, Chinese patent with publication number "CN118810224A" discloses "a double-sided hot stamping device" which can synchronously drive the hot stamping template and the upper hot stamping template toward the printed material to perform double-sided printing on both sides of the printed material through a drive component, or synchronously drive the two to move away from the printed material after hot stamping is completed, so that subsequent printed materials can move.

[0004] Although the drive components can synchronously drive the hot stamping stencil and the upper hot stamping stencil toward the printed material for double-sided printing on both sides, or synchronously drive them to move away from the printed material after hot stamping to facilitate subsequent printing, the above structure cannot effectively adapt to materials of different thicknesses when moving materials. Moreover, the above structure also reveals that the material cannot be effectively positioned and limited during processing, which can lead to material displacement or jitter. Utility Model Content

[0005] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a double-sided hot stamping device to solve the problem of double-sided hot stamping.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A double-sided hot stamping device includes a housing with a processing chamber inside. A servo motor is fixedly installed at the center of the upper end of the housing. A threaded rod is fixedly installed on the output shaft of the servo motor. A fixed post is threadedly connected to the outer ring of the threaded rod. An upper hot stamping plate is fixedly installed at the end of the fixed post away from the threaded rod. The upper hot stamping plate is slidably installed on both sides of the processing chamber. Lower hot stamping plates are fixedly installed on both sides of the processing chamber below the upper hot stamping plate. Cylinders are fixedly installed on both sides of the servo motor at the upper end of the housing. An upper positioning plate is fixedly installed on the output shaft of each of the two cylinders. Lower positioning plates are fixedly installed on both sides of the processing chamber below the upper positioning plates. Two limiting rollers are rotatably installed inside the upper and lower positioning plates. Multiple brushes are provided on both sides of the opposite surfaces of the upper and lower positioning plates. Two drawers are slidably installed on both sides of the processing chamber below the lower positioning plates.

[0008] As a preferred technical solution, a circular opening is provided inside the upper end of the housing at the position of the servo motor, and an internal thread is provided inside the fixing column. The threaded rod is threadedly connected to the internal thread provided inside the fixing column through the circular opening.

[0009] As a preferred technical solution, four support rods are fixedly installed at the position of the servo motor on the upper end of the housing. The ends of the four support rods away from the housing are fixedly installed at the bottom of the servo motor, and the servo motor is fixedly installed on the upper end of the housing through the support rods.

[0010] As a preferred technical solution, the processing chamber has limiting grooves on both sides of the upper hot stamping plate, and connecting plates are fixedly installed on both sides of the upper hot stamping plate. A limiting block is fixedly installed on the end of the connecting plate away from the upper hot stamping plate, and the limiting block is slidably installed inside the limiting groove.

[0011] As a preferred technical solution, mounting plates are fixedly installed on both sides of the processing chamber at both ends of the lower hot stamping plate. Both ends of the lower hot stamping plate are fixedly installed on the mounting plate at the end away from the processing chamber. The lower hot stamping plate is fixedly installed inside the processing chamber by the mounting plates.

[0012] As a preferred technical solution, the processing chamber has sliding grooves on both sides of the two upper positioning plates. Limiting rods are fixedly installed inside the sliding grooves. Sliding blocks are integrally formed at both ends of the two upper positioning plates. Limiting grooves are opened inside the sliding blocks. The sliding blocks are slidably installed inside the sliding grooves. The sliding blocks slide on the outer ring of the limiting rods through the limiting grooves opened inside.

[0013] As a preferred technical solution, the upper hot stamping plate has two rectangular slots inside, and the rotatable limiting roller inside the upper positioning plate is rotatably installed inside the upper positioning plate through the rectangular slots. The lower positioning plate has two sliding slots inside, and the rotatable limiting roller inside the lower positioning plate is rotatably installed inside the lower positioning plate through the sliding slots.

[0014] As a preferred technical solution, both ends of the processing chamber have integrally formed connecting blocks on both sides, and both sides of the drawer have connecting grooves. The drawer is slidably connected to the outer ring of the connecting blocks through the connecting grooves on both sides, and the drawer is located below the lower positioning plate.

[0015] In summary, the present invention has the following main advantages:

[0016] First, the staff places the material on the upper part of the lower positioning plate. Then, the staff starts the cylinder, which pushes the upper positioning plate, which is fixedly installed on the cylinder output shaft, to move up and down. With the help of the lower positioning plate, the material can be effectively positioned and fixed. Two limit rollers are rotatably installed inside the upper and lower positioning plates. The function of these limit rollers is to help keep the paper or other materials flat during the hot stamping process and prevent them from shifting or wrinkling. In addition, multiple brushes are provided on the opposite sides of the upper and lower positioning plates. These brushes can further ensure the stable delivery of the material and clean the dust on the top and bottom sides of the material, thus improving the hot stamping quality.

[0017] Secondly, the staff then pushes the material between the upper and lower hot stamping plates. Since the upper hot stamping plate is fixedly installed at the end of the fixed column away from the threaded rod, and the fixed column moves up and down under the drive of the threaded rod, the upper hot stamping plate also moves up and down on both sides of the processing chamber. Limiting blocks are fixedly installed on both sides of the upper hot stamping plate through connecting plates. These limiting blocks are slidably installed in the limiting grooves opened on both sides of the processing chamber, ensuring the stability and accuracy of the upper hot stamping plate during the lifting process, which can effectively improve the processing of materials.

The limiting rollers 12 that rotate inside the upper positioning plate 5 are rotatably installed inside the upper positioning plate 5 through the rectangular grooves 13. The lower positioning plate 6 has two sliding grooves 14 inside. The limiting rollers 12 that rotate inside the lower positioning plate 6 are rotatably installed inside the lower positioning plate 6 through the sliding grooves 14. Under the action of the limiting rollers 12, the material can be better fixed and limited, preventing displacement and shaking during processing.

[0030] refer to Figures 1 to 4The processing chamber 4 has integrally formed connecting blocks 21 on both sides of its interior. The drawer 7 has connecting grooves 20 on both sides. The drawer 7 is slidably connected to the outer ring of the connecting blocks 21 through the connecting grooves 20 on both sides. The drawer 7 is located below the lower positioning plate 6. The drawer 7 can effectively collect dust and waste materials, improving the ease of cleaning for workers.

[0031] Operating principle and advantages: During use, the operator places the material on the upper end of the lower positioning plate 6. Then, the operator activates cylinder 2, causing the output shaft of cylinder 2 to push the upper positioning plate 5, which is fixedly installed on the output shaft of cylinder 2, to move up and down. Combined with the action of the lower positioning plate 6, this effectively positions and fixes the material. Two limiting rollers 12 are rotatably installed inside both the upper and lower positioning plates 5 and 6. These limiting rollers 12 help keep the paper or other materials flat during the hot stamping process, preventing them from shifting or wrinkling. In addition, multiple brushes 15 are provided on the opposite sides of the upper and lower positioning plates 5 and 6. These brushes 15 further ensure stable material transport and clean dust from the top and bottom of the material, improving the hot stamping quality. Two drawers 7 are slidably installed on both sides of the processing chamber 4, below the lower positioning plate 6, for convenient collection. The brush 15 collects dust and foreign objects, which can be easily pulled out and emptied before being reinstalled, effectively improving the ease of cleaning for workers. Next, workers push the material between the upper hot stamping plate 10 and the lower hot stamping plate 11. Since the upper hot stamping plate 10 is fixedly installed at the end of the fixing column 9 away from the threaded rod 28, and the fixing column 9 moves up and down under the drive of the threaded rod 28, the upper hot stamping plate 10 also moves up and down on both sides inside the processing chamber 4. Limiting blocks 23 are fixedly installed on both sides of the upper hot stamping plate 10 via connecting plates 24. These limiting blocks 23 slide inside the limiting grooves 25 opened on both sides of the processing chamber 4, ensuring the stability and accuracy of the upper hot stamping plate 10 during the lifting process, effectively improving the material processing effect. After processing, workers can push the material to the other end of the box 3 for easy removal.
