A device for hot stamping dynamic patterns on splicing paper Technical Field

[0001] This invention relates to the field of hot stamping technology, and in particular to a hot stamping device for dynamic patterns on splicing paper. Background Technology

[0002] Hot stamping is a process that uses heat transfer to transfer the aluminum layer from electroplated aluminum foil onto the surface of a substrate, creating a unique metallic effect. Because the main material used in hot stamping is electroplated aluminum foil, it is also called electroplated aluminum foil stamping. In roller-type hot stamping equipment, hot stamping modules are installed on the hot stamping rollers. The pattern engraved on the hot stamping module determines the pattern stamped on the item. In enterprise production processes, some hot stamping production lines require frequent changes to the hot stamping pattern. However, a single hot stamping module typically only has one fixed pattern engraved. Therefore, each time a hot stamping pattern is changed, the hot stamping module needs to be disassembled and replaced. This process requires stopping the hot stamping production line, severely hindering production efficiency. To address these problems, this application proposes an improvement.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to Figures 1-9. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Example:

[0030] As shown in Figures 1 to 9, this invention discloses a dynamic pattern hot stamping device for splicing paper, including a left roller frame 11 and a right roller frame 12. A hot stamping roller 2 is rotatably arranged between the left roller frame 11 and the right roller frame 12. Three mounting grooves 21 are axially formed on the side wall of the hot stamping roller 2. Each mounting groove 21 is equipped with a hot stamping mechanism, which includes a mounting base 3, a first hot stamping module 4, and a second hot stamping module 5. The first hot stamping module 4 and the second hot stamping module 5 are located in the mounting groove 21, and the mounting base 3 is fixedly covered in the mounting groove 21. The mounting base 3 has a module opening 31 in the middle. The module opening 31 can only expose one of the first hot stamping module 4 and the second hot stamping module 5. The first hot stamping module 4 and the second hot stamping module 5 are provided with different hot stamping patterns. The hot stamping roller 2 is provided with a pattern changing mechanism for switching the position of the first hot stamping module 4 and the second hot stamping module 5. By changing the position of the first hot stamping module 4 and the second hot stamping module 5 through the pattern changing mechanism, the first hot stamping module 4 and the second hot stamping module 5 can be switched to be exposed from the module opening 31, thereby changing the hot stamping pattern.

[0031] Furthermore, the first hot stamping module 4 has an upper inclined block 41 on the bottom side facing the second hot stamping module 5, and the second hot stamping module 5 has a lower inclined block 51 on the bottom side facing the first hot stamping module 4 for cooperating with the upper inclined block 41. The pattern changing mechanism includes a module moving mechanism for driving the second hot stamping module 5 to move toward the first hot stamping module 4. When the module moving mechanism drives the second hot stamping module 5 to move toward the first hot stamping module 4, the second hot stamping module 5 presses against the upper inclined block 41 of the first hot stamping module 4 through the lower inclined block 51, thereby causing the first hot stamping module 4 to be pressed down.

[0032] Specifically, the module moving mechanism includes a movable rod 6, and a movable hole 22 is provided at the axis of the hot stamping roller 2. The movable rod 6 is movably fitted in the movable hole 22. The movable rod 6 is aligned with the axis of the hot stamping roller 2. A support leg 52 is provided at the lower end of the second hot stamping module 5. The lower end of the support leg 52 is connected to the movable rod 6. Therefore, when the movable rod 6 is pushed, the second hot stamping module 5 can be driven through the support leg 52.

[0033] Next, the pattern changing mechanism also includes a prismatic rod 63 rotatably connected to the movable rod 6. Each of the first hot stamping modules 4 has a prismatic rod 63 located below it. The hot stamping roller 2 has a prismatic hole 23 in the movable hole 22 for the prismatic rod 63 to slide within it. That is, the prismatic rod 63 can only slide left and right within the prismatic hole 23 and cannot rotate. Note that the prismatic hole 23 should be slightly larger than the movable hole 22 to facilitate the entry of the movable rod 6. Additionally, the hot stamping roller 2 has a penetrating movable hole 22 and a prismatic rod 63 on the lower side of the mounting groove 21. The control port 24 inside the shaped hole 23 has an axial guide groove 64 on the prismatic rod 63. A telescopic sleeve 42 is slidably connected to the axial guide groove 64. The support leg 52 and the telescopic sleeve 42 both pass upward through the control port 24. The support leg 52 and the telescopic sleeve 42 can only slide left and right within the control port 24. The front and rear sides are limited by the control port 24. A telescopic rod 43 is movably arranged on the telescopic sleeve 42. The telescopic rod 43 is connected to the first hot stamping module 4. A compression spring 44 is provided inside the telescopic sleeve 42 to abut against the telescopic rod 43.

[0034] In addition, the movable rod 6 also includes an eccentric rod 61 located below each of the second hot stamping modules 5. The axis of the eccentric rod 61 is offset from the axis of the movable hole 22 and the axis of the movable rod 6. An annular guide groove 62 is provided on the outer side wall of the eccentric rod 61. The lower end of the support leg 52 is movably connected in the annular guide groove 62. That is to say, when the movable rod 6 rotates, it drives the eccentric rod 61 to rotate. The eccentric rod 61 can drive the second hot stamping module 5 to move radially relative to the hot stamping roller 2 through the support leg 52.

[0035] The structure for driving the movable rod 6 to move left and right and rotate is as follows: the left end of the movable rod 6 penetrates through the hot stamping roller 2. A hydraulic cylinder 7 is provided on the left roller frame 11. The output shaft of the hydraulic cylinder 7 is rotatably connected to the movable rod 6. In addition, a limit groove 65 is axially opened on the left end of the movable rod 6, and a driven gear 81 is sleeved on the left end of the movable rod 6. The driven gear 81 is provided with a limit key 82 that slides in the limit groove 65. An L-shaped plate 111 can be provided on the left roller frame 11 to prevent the driven gear 81 from sliding left and right. A motor 83 is provided on the left roller frame 11. A drive gear 84 is provided on the output shaft of the motor 83. A toothed belt 85 is provided between the drive gear 84 and the driven gear 81. It should be noted that the motor 83 does not have a self-locking function and will not lock the rotation of the hot stamping roller 2. In addition, the motor 83 can only drive the movable rod 6 to rotate and cannot drive the entire hot stamping roller 2 to rotate because the drive mechanism that drives the entire hot stamping roller 2 to rotate has a self-locking function.

[0036] The working principle of this invention is as follows: As shown in Figure 2, when the first hot stamping module 4 is exposed from the module opening 31, a switch is needed to expose the second hot stamping module 5 from the module opening 31. The hydraulic cylinder 7 drives the movable rod 6 to move to the right. The movable rod 6, through the support leg 52, moves the second hot stamping module 5 towards the first hot stamping module 4. The prismatic rod 63 also moves to the right with the movable rod 6. However, since the first hot stamping module 4 is located on the module opening 31, it cannot move to the right at this time. Therefore, the telescopic sleeve 42 below the first hot stamping module 4 slides relative to the prismatic rod 63, and the second hot stamping module 5 approaches the first hot stamping module 4. The second hot stamping module 5 presses against the upper inclined block 41 of the first hot stamping module 4 through the lower inclined block 51, thus pressing the first hot stamping module 4 downwards. When the first hot stamping module 4 is pressed downwards away from the module opening 31, it is pushed to the right by the second hot stamping module 5. When the second hot stamping module 5 reaches below the module opening 31, the motor 83 drives the movable rod 6 to rotate. During the rotation, the eccentric rod 61 on the movable rod 6 drives the second hot stamping module 5 to move upward, so that the second hot stamping module 5 is exposed from the module opening 31, thus completing the position switch. When it is necessary to switch again, the motor 83 first drives the movable rod 6 to rotate, so that the eccentric rod 61 drives the second hot stamping module 5 downward away from the module opening 31. Then the hydraulic cylinder 7 drives the movable rod 6 to move to the left. At this time, the second hot stamping module 5 is driven to move to the left. The first hot stamping module 4 needs to wait until the telescopic sleeve 42 reaches the rightmost end of the axial guide groove 64 before it is driven to move to the left by the prism rod 63. At this time, the upper inclined block 41 on the first hot stamping module 4 has already separated from the lower inclined block 51 of the second hot stamping module 5. Therefore, after the first hot stamping module 4 reaches the module opening 31, it is pushed upward by the compression spring 44 and exposed from the module opening 31.

[0037] In order to better limit the front and rear positions of the first hot stamping module 4 and the second hot stamping module 5 and maintain the stability of switching between the first hot stamping module 4 and the second hot stamping module 5, a limiting plate 32 is provided in the mounting base 3 on the front and rear sides of the first hot stamping module 4 and the second hot stamping module 5.

[0038] Since the first hot stamping module 4 has a compression spring 44 below it, in order to prevent the first hot stamping module 4 from retracting into the module opening 31 when it is pressed against the electroplated aluminum, the mounting base 3 is provided with an electromagnet 91 at the position of the module opening 31. The left and right sides of the first hot stamping module 4 are provided with limiting suction plates 45, which are made of magnetic material. When the first hot stamping module 4 is exposed from the module opening 31, the electromagnet 91 is energized and attracts the limiting suction plates 45 on the first hot stamping module 4, thereby fixing the first hot stamping module 4.

[0039] In addition, the mounting base 3 is provided with an electric heating plate 92 on the side facing the first hot stamping module 4 and the second hot stamping module 5. The electric heating plate 92 is powered on to heat the first hot stamping module 4 and the second hot stamping module 5.

[0040] It should also be noted that the right roller frame 12 is provided with a conductive slip ring 93 on the outer sleeve of the hot stamping roller 2. Since the hot stamping roller 2 rotates continuously during operation, a conductive slip ring 93 is required to connect the electromagnet 91 and the electric heating plate 92 to make the wire harness rotatably connected. The conductive slip ring 93 is existing technology, and its internal structure will not be described in detail here.

[0041] It should also be noted that the terms used in this invention, such as "front," "rear," "vertical," "horizontal," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the scope of protection of this invention.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
