Description

A laminating machine for intermittent hot stamping Technical Field

[0001] This utility model relates to a laminating machine, and more particularly to a laminating machine for intermittent hot stamping. Background Technology

[0002] The paper and film to be hot-stamped pass between the hot stamping pressure roller and the hot stamping traction roller of the hot stamping roller group. The hot stamping pressure roller applies the hot stamping pattern on the film to the paper, completing the hot stamping operation. In order to make the hot stamping pattern on the film correspond to the hot stamping position on the paper, and to ensure hot stamping efficiency and quality, the spacing between two adjacent hot stamping pattern areas on the foil film needs to be matched with the spacing between two adjacent hot stamping positions on the film. However, the material between two hot stamping pattern areas on the film will be wasted. Summary of the Invention

[0003] In view of the technical problems existing in the background art, the present invention aims to provide a laminating machine for intermittent hot stamping, in which the film material remains stationary after hot stamping while the paper moves, thereby shortening the gap between two hot stamping patterns and saving materials.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: This intermittent hot stamping laminating machine includes a frame, on which a film feeding roller group, a hot stamping roller group, a feeding assembly, and a discharging assembly are provided. The film feeding roller group forms a film feeding path and includes an unwinding roller, a rewinding roller, and a guide roller. The hot stamping roller group is disposed on the film feeding path and is lower than the film feeding roller group. The hot stamping roller group includes a hot stamping pressure roller and a hot stamping traction roller that cooperate with each other. The hot stamping pressure roller is close to or away from the hot stamping traction roller and is located at the hot stamping traction roller. Above, the feeding assembly is disposed on the feeding side of the hot stamping roller group, and the discharging assembly is disposed on the discharging side of the hot stamping roller group. It also includes a hot stamping pattern spacing control assembly that cooperates with the hot stamping roller group. The hot stamping pattern spacing control assembly includes a braking roller and a pull-back roller. The braking roller is close to or away from the guide roller. On the film feeding path, the guide roller is located between the unwinding roller and the hot stamping roller group. The pull-back roller is disposed on a second mounting base, which is reciprocatingly positioned. On the film feeding path, the pull-back roller is located between the guide roller and the hot stamping roller group.

[0005] In this scheme, after hot stamping is completed, the brake roller approaches and abuts against the guide roller, the hot stamping pressure roller resets, the pull-back roller moves to tighten the film strip, and at the same time, part of the film strip returns from the discharge side of the hot stamping pressure roller to the feed side. At this time, the film strip does not move, but the paper moves, which effectively shortens the gap between the two hot stamping patterns. The pull-back roller swings back and forth or moves back and forth in one direction.

[0006] Preferably, the second mounting base is oscillating and hinged to the output end of the pull-back cylinder.

[0007] In this scheme, the output end of the pull-back cylinder drives the second mounting base to swing, so that the pull-back roller, together with the hot stamping roller, controls the tension of the film belt.

[0008] Preferably, the brake roller is mounted on a third mounting base, the third mounting base is oscillating, and the third mounting base is hinged to the output end of the brake cylinder.

[0009] In this scheme, the output end of the brake cylinder drives the third mounting seat to swing, so that the brake roller moves closer to or further away from the guide roller.

[0010] Preferably, the hot stamping roller is mounted on a first mounting base, the first mounting base is oscillating, and the first mounting base is hinged to the output end of the hot stamping cylinder.

[0011] In this scheme, the output end of the hot stamping cylinder drives the first mounting seat to swing, so that the hot stamping pressure roller moves closer to or further away from the hot stamping traction roller.

[0012] Preferably, the feeding assembly includes a feeding traction roller and a feeding conveyor belt, the feeding traction roller is wound with the feeding conveyor belt, and the feeding traction roller is equipped with a pressure roller.

[0013] In this scheme, the feeding traction roller can both drive the feeding conveyor belt and work with the pressure roller to feed the paper into the hot stamping roller group.

[0014] Preferably, the discharge assembly includes a discharge conveyor belt and a discharge traction roller, the discharge traction roller connecting the discharge conveyor belt and the hot stamping roller group, and the discharge traction roller is equipped with a pressure roller.

[0015] In this scheme, the discharge traction roller works in conjunction with the pressure roller to remove the paper from between the hot stamping rollers.

[0016] Preferably, the discharge traction roller, the feed traction roller, and the hot stamping traction roller are linked together.

[0017] In this solution, the three components operate at the same linear speed, enabling smooth paper transport, and the drive structure is simple.

[0018] Preferably, the hot stamping roller has a heating chamber inside, and the heating chamber has stirring blades inside.

[0019] In this scheme, the agitator blades fully drive the water or heat transfer oil to circulate, preventing water or oil from remaining inside the roller, stabilizing the roller surface temperature, and ensuring the coating speed and coating quality.

[0020] Preferably, a gap is provided between the feeding conveyor belts for the installation of side baffles, and the side baffles are laterally movable and adjustable on the frame.

[0021] In this scheme, a side baffle is set to position the paper input horizontally.

[0022] The beneficial effects of this utility model are as follows: after hot stamping, the brake roller approaches and abuts against the guide roller, the hot stamping pressure roller resets, and the pull-back roller actuates to tighten the film strip. At the same time, part of the film strip returns from the discharge side of the hot stamping pressure roller to the feed side. At this time, the film strip remains stationary while the paper moves, effectively shortening the gap between the two hot stamping patterns. Therefore, this utility model has substantial features and progress compared with the prior art. Attached Figure Description

[0030] In the description of this application, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated.

[0031] Referring to Figures 1-3, an intermittent hot stamping laminating machine according to this embodiment includes a frame 24. The frame 24 is provided with a film feeding roller group 1, a hot stamping roller group 5, a feeding assembly 8, and a discharging assembly 9. The film feeding roller group 1 forms a film feeding path and includes an unwinding roller 2, a winding roller 3, and a guide roller 4. The hot stamping roller group 5 is disposed on the film feeding path and is lower than the film feeding roller group 1. The hot stamping roller group 5 includes a hot stamping pressure roller 6 and a hot stamping traction roller 7 that cooperate with each other. The hot stamping pressure roller 6 is close to or away from the hot stamping traction roller 7 and is located above the hot stamping traction roller 7. The feeding assembly 8 is disposed on the feeding side of the hot stamping roller group 5, and the discharging assembly 9 is disposed on the discharging side of the hot stamping roller group 5. The hot stamping pressure roller 6 is provided with a heating chamber, and the heating chamber is provided with stirring blades.

[0032] The system also includes a hot stamping pattern spacing control component 10 that cooperates with the hot stamping roller group 5. The hot stamping pattern spacing control component 10 includes a brake roller 11 and a pull-back roller 12. The brake roller 11 is close to or away from the guide roller 4. On the film feeding path, the guide roller 4 is located between the unwinding roller 2 and the hot stamping roller group 5. The pull-back roller 12 is disposed on a second mounting base 13. The second mounting base 13 is reciprocating. On the film feeding path, the pull-back roller 12 is located between the guide roller 4 and the hot stamping roller group 5.

[0033] In this embodiment, the paper conveying direction is defined as from front to back (longitudinal). The film feeding roller group 1 also includes a winding roller with the same function as the guide roller 4. The paper has at least two positions to be hot stamped, and the film feeding path is V-shaped. During hot stamping, the brake roller 11 moves away from the guide roller 4 to release the film, the pull-back roller 12 resets, and the hot stamping pressure roller 6 moves close to the hot stamping traction roller 7 to press the film onto the paper. Then, the film and the paper move synchronously, and the hot stamping pattern is attached to the hot stamping position. After hot stamping is completed, the brake roller 11 presses the film onto the guide roller 4, the hot stamping pressure roller 6 resets, and the pull-back roller 12 actuates to tension the film. Part of the film strip is returned from the discharge side of the hot stamping roller 6 to the feed side. The film strip is pulled forward, and the paper is pulled backward by the discharge assembly 9. The film strip and the paper are reliably separated. The take-up roller 3 and the unwind roller 2 are mature technologies, and the unwind roller 2 can actively unwind. The discharge assembly 9 and the feed assembly 8 are mature technologies. They can be fed by a robotic arm or be continuous paper strips. The hot stamping roller 6 can be raised and lowered or swing. The pull-back roller 12 and the brake roller 11 can swing or move in one direction. The hot stamping roller 6 can also be electromagnetically heated, which is a mature technology.

[0034] Referring to Figure 3, the second mounting base 13 is oscillating and hinged to the output end of the pull-back cylinder 14. The output end of the pull-back cylinder 14 drives the second mounting base 13 to oscillate, so that the pull-back roller 12 cooperates with the hot stamping roller 6 to control the tension of the film belt. The brake roller 11 is mounted on the third mounting base 15, which is oscillating and hinged to the output end of the brake cylinder 16. The hot stamping roller 6 is mounted on the first mounting base 17, which is oscillating and hinged to the output end of the hot stamping cylinder 18.

[0035] In this embodiment, the brake roller 11, pull-back roller 12, and hot stamping roller 6 are all oscillatingly arranged. The drive structure for pull-back and braking is vertical and is located above the hot stamping roller 6, making the film feeding roller group 1 sufficiently compact. The hot stamping drive structure provides installation space for the pull-back and braking drive structure. The hot stamping cylinder 18 can be located on both sides below the hot stamping roller 6.

[0036] Referring to Figures 1-2, the feeding assembly 8 includes a feeding traction roller 19 and a feeding conveyor belt 20. The feeding traction roller 19 is wound with the feeding conveyor belt 20 and is equipped with a pressure roller. The discharging assembly 9 includes a discharging conveyor belt 21 and a discharging traction roller 22. The discharging traction roller 22 connects the discharging conveyor belt 21 and the hot stamping roller group 5. The discharging traction roller 22 is equipped with a pressure roller. The discharging traction roller 22, the feeding traction roller 19, and the hot stamping traction roller 7 are linked together. A gap is provided between the feeding conveyor belts 20 for the side baffles 23 to be installed. The side baffles 23 are laterally adjustable and mounted on the frame 24.

[0037] In this embodiment, photoelectric eyes can be configured between the pressure rollers (not shown in the figure) to sense the position of the paper, so as to control the hot stamping roller group 5 to respond in a timely manner. There is no need to control the spacing of the paper. This is a mature technology. For paper of different specifications, the lateral position of the side baffle 23 can be adjusted to adapt to the width difference of the paper and to perform lateral positioning of the paper. The adjustment method of the side baffle 23 is specifically a sliding positioning connection.

[0038] The above description represents the preferred embodiment of this utility model. It should be noted that the scope of protection of this utility model is not limited thereto. For those skilled in the art, various improvements, modifications, or equivalent substitutions can be made without departing from the equivalent inventive concept disclosed in this utility model, and these can also be considered as part of the scope of protection of this utility model.
