Description

Technical Field

[0001] The utility model belongs to the technical field of hot stamping machines, and in particular relates to a retractable device for hot stamping machines. Background Art

[0002] The hot stamping process uses the principle of heat transfer to transfer the aluminum layer in the electroplated aluminum to the surface of the substrate to form a special metal effect. Since the main material used for hot stamping is electroplated aluminum foil, hot stamping is also called electroplated aluminum hot stamping. Electroplated aluminum foil is usually composed of multiple layers of materials, the base material is usually PE, followed by separation coating, color coating, metal coating (aluminum plating) and glue coating.

[0003] In the printing industry, hot stamping of electrochemical aluminum foil on paper is commonly used, which is called hot stamping. Hot stamping is a general term for a process. Hot stamping does not mean that the hot stamping is gold. There are many kinds of hot stamping paper materials, including gold, silver, laser gold, laser silver, black, red, green and so on.

[0004] In the existing hot stamping machine winding device, the unwinding roller and the winding roller for placing the hot stamping film are mostly installed at corresponding positions and are in an unadjustable state. Since the hot stamping film is reusable, after a roll of hot stamping film is used up, the hot stamping film roll located at the winding position needs to be disassembled and installed at the unwinding position. The overall operation is rather cumbersome. Therefore, a hot stamping machine winding device is needed to assist in solving this problem. Utility Model Content

The scanner 14 can ensure the integrity of the hot stamping film during the hot stamping process, thereby ensuring the smooth progress of the subsequent paper hot stamping work.

[0028] Reference Figure 1 , Figure 3 and Figure 4As shown, the rotating assembly 17 includes a support frame 18 fixed to the mounting frame 1. A worm gear disc 19 is rotatably embedded at the center of the support frame 18. An adjusting motor 21 is installed on one side of the support frame 18. A worm 211 is installed at the front end of the motor shaft of the adjusting motor 21. The worm gear disc 19 and the worm 211 are in transmission cooperation. A plug post 20 is vertically fixed at the center of the worm gear disc 19. A rotating frame 181 is sleeved on the plug post 20. The overall center of gravity of the rotating frame 181 is on the plug post 20, ensuring that the overall rotating assembly 17 is more stable and minimizing the shaking of the rotating assembly 17 during operation. The first hot stamping film winding and unwinding roller 15 and the second hot stamping film winding and unwinding roller 16 are respectively installed at both ends of the rotating frame 181.

[0029] Through the set rotating assembly 17, through the rotating assembly 17 arranged at the bottom of the mounting frame 1, after the hot stamping film is used up, the positioning pin 22 is completely pulled out, and the adjusting motor 21 is started. The adjusting motor 21 drives the worm 211 to rotate. The worm 211 and the worm gear disc 19 are in transmission cooperation, so that the entire worm gear disc 19 rotates, and then drives the entire plug post 20 to rotate. During the rotation of the plug post 20, the entire rotating frame 181 is driven to rotate, so that the positions of the first hot stamping film winding and unwinding roller 15 and the second hot stamping film winding and unwinding roller 16 are swapped by 180 degrees as a whole. After the position of the first hot stamping film winding and unwinding roller 15 is changed, the adjusting motor 21 is inserted into the corresponding mounting hole 182, thus completing the swapping of the overall positions of the first hot stamping film winding and unwinding roller 15 and the second hot stamping film winding and unwinding roller 16, avoiding the situation of disassembling, replacing, and adjusting the position after a hot stamping film roll is used up, and improving the efficiency of replacing the hot stamping film roll.

[0033] During operation, the servo motor is started synchronously, and the servo motor drives the paper winding roller and the first hot stamping film rewinding roller 15 and the second hot stamping film rewinding roller 16 to rotate, so that the paper passes through the limiting support shaft 7, the guide rod 8, and the hot stamping pressure roller 11 in sequence and is wound on the paper winding roller, and the hot stamping film passes through the unwinding roller 13, the guide rod 8, and the hot stamping roller 12 in sequence and is wound and installed on the first hot stamping film rewinding roller 15, so that the hydraulic rod 10 is extended as a whole. In the process of extending the hydraulic rod 10, the hot stamping pressure roller 11 is driven to descend as a whole, and the hot stamping pressure roller 11 is pressed between the hot stamping rollers 12.

[0034] After the hot stamping film is used up, the positioning pin 22 is pulled out as a whole, and the adjusting motor 21 is started. The adjusting motor 21 drives the worm 211 to rotate, and the worm 211 cooperates with the worm wheel 19 for transmission, so that the worm wheel 19 rotates as a whole, and then drives the plug column 20 to rotate as a whole. During the rotation of the plug column 20, the rotating frame 181 is driven to rotate as a whole, so that the positions of the first hot stamping film rewinding roller 15 and the second hot stamping film rewinding roller 16 are swapped 180 degrees as a whole. After the first hot stamping film rewinding roller 15 is changed, the adjusting motor 21 is inserted into the corresponding mounting hole 182, thereby completing the overall position swap of the first hot stamping film rewinding roller 15 and the second hot stamping film rewinding roller 16, thereby avoiding the situation where a hot stamping film roll needs to be disassembled, replaced and adjusted after use.

[0035] All technical features in this embodiment can be freely combined according to actual needs.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein.
