DETAILED DESCRIPTION

[0036] The following is combined with Figure 1-6 This application is described in further detail.

[0037] This application discloses a high-precision automatic hot stamping machine. Figure 1 and Figure 2The high-precision automatic hot stamping machine includes a workbench 1 and a mounting frame 11 mounted on the workbench 1. Mounting frame 11 includes a pusher 12 and a hot stamping plate 2 located at the output end of pusher 12. Pusher 12 can be configured as a pneumatic cylinder. During printing, the printed sheet 01 and hot stamping foil are sequentially placed on the workbench 1, aligned with the hot stamping plate 2. Pusher 12 then moves the hot stamping plate 2 toward the workbench 1, causing printing to proceed.

[0038] Reference Figure 1 and Figure 2 A pressing frame 3 and an elastic component 4 are provided on the workbench 1. The pressing frame 3 is connected to the workbench 1 via the elastic component 4. The elastic component 4 includes an outer sleeve 41, an inner rod 42, and a first elastic member 43. The outer sleeve 41 is arranged perpendicular to the workbench 1, and the inner rod 42 slides within the outer sleeve 41. The first elastic member 43 can be configured as a spring, which is sleeved on the outside of the inner rod 42. The pressing frame 3 is connected to the end of the inner rod 42 facing away from the workbench 1. One end of the first elastic member 43 is connected to the outer sleeve 41, and the other end is connected to the pressing frame 3. The first elastic member 43 is used to drive the inner rod 42 to move away from the workbench 1. Before printing, the pressing frame 3 is pushed toward the workbench 1 until it moves to abut against the plate 01, thereby securing the plate 01. Hot stamping is then performed to reduce wrinkles on the plate 01 when the hot stamping plate 2 contacts the plate 01, keeping the plate 01 flat and improving printing quality.

[0039] Reference Figure 1 and Figure 2 A push rod 5 is provided at the output end of the push member 12. The push rod 5 is connected to the hot stamping plate 2. A push plate 51 is sleeved on the outside of the push rod 5. The push plate 51 is slidably arranged on the outside of the push rod 5 along the length direction of the push rod 5. The push plate 51 is bent in the direction toward the pressing frame 3 to form a pushing portion 511. A second elastic member 52 is sleeved on the outside of the push rod 5. The second elastic member 52 can be a spring. The second elastic member 52 is arranged between the hot stamping plate 2 and the push plate 51, and the two ends of the second elastic member 52 are respectively connected to the hot stamping plate 2 and the push plate 51. The elastic force of the second elastic member 52 is greater than the elastic force of the first elastic member 43. When the hot stamping plate 2 moves, it drives the push plate 51 to move. When the hot stamping plate 2 moves to the pressing frame 3, the pushing portion 511 moves to abut against the pressing frame 3. The push rod 5 continues to move, driving the pressing frame 3 toward the plate 01 through the pushing portion 511. After the pressing frame 3 is completely pressed into contact with the plate 01, the push rod 5 drives the hot stamping plate 2 to move to the plate 01 for printing. As the push rod 5 moves, the pressing frame 3 and the hot stamping plate 2 sequentially abut against the plate 01, thereby improving printing efficiency.

[0040] Reference Figure 2 and Figure 3The pressing frame 3 is provided with multiple pressing frames 6, which are located on the side of the pressing frame 3 close to the workbench 1. Multiple pressing frames 3 are arranged at intervals around the plate 01. Pressing rods 61 are provided on the pressing frames 6, extending along the length of the pressing frames 6 and located on the side of the pressing frame 6 close to the workbench 1. When the pressing frame 3 moves, the pressing frames 6 drive the pressing rods 61 to contact the plate 01, thereby limiting and fixing the plate 01.

[0041] Reference Figure 3 and Figure 4 A mounting plate 7 is provided on the pressing frame 3. The pressing frame 6 and the pressing frame 3 are spaced apart. There are multiple groups of mounting plates 7 corresponding to the multiple pressing frames 6. Each group of mounting plates 7 includes two mounting plates 7, and the two mounting plates 7 are respectively provided at both ends of the pressing frame 6. A mounting rod 62 is provided at the end of the pressing frame 6. A guide groove 71 is provided on the mounting plate 7 in the horizontal direction. The end of the guide groove 71 away from the interior of the workbench 1 is inclined in the direction away from the workbench 1. The mounting rod 62 slides in the guide groove 71 along the length direction of the guide groove 71. In the initial state, the mounting rod 62 is placed at the end of the guide groove 71 close to the interior of the workbench 1. After the pressing frame 3 moves and drives the pressing rod 61 to abut against the plate 01, the pressing frame 3 continues to move, driving the mounting rod 62 to move in the guide groove 71, driving the pressing frame 3 to move horizontally away from the interior of the workbench 1. By driving the pressing rod 61 to abut against different positions on the plate 01, the plate 01 is unfolded, thereby improving the flatness of the plate 01 during printing.

[0042] Reference Figure 3 and Figure 5 , two adjacent pressing frames 6 are perpendicular to each other, and an auxiliary component 8 is provided between the two adjacent pressing frames 6. The auxiliary component 8 includes an auxiliary sleeve 81, an auxiliary frame 82 and an auxiliary rod 83. The middle position of the auxiliary frame 82 corresponds to the middle position of the ends of the two adjacent pressing frames 6, and the angles between the auxiliary frame 82 and the two pressing frames 6 are the same, that is, they are all 45 degrees. There are at least two auxiliary sleeves 81 corresponding to the two pressing frames 6. The auxiliary sleeve 81 is sleeved on the outside of the auxiliary frame 82, and the side of the auxiliary sleeve 81 is connected to the pressing frame 6. The auxiliary sleeve 81 is slidably provided on the auxiliary frame 82 along the length direction of the auxiliary frame 82. The auxiliary rod 83 is provided on the side of the auxiliary frame 82 close to the workbench 1. When the pressing rod 61 is in contact with the layout 01, the auxiliary rod 83 is also in contact with the layout 01. When the pressing frame 6 moves, the auxiliary frame 82 is driven to move synchronously through the auxiliary sleeve 81, and the auxiliary rod 83 is driven to move at the same time. Under the action of the pressing rod 61 and the auxiliary rod 83, multiple positions on the layout 01 are evenly contacted, and the layout 01 is evenly expanded as a whole, further improving the printing quality.

[0043] Reference Figure 3 and Figure 5A third elastic member 811 is disposed between the two auxiliary sleeves 81. The third elastic member 811 can be configured as a spring, with both ends of the spring connected to the two auxiliary sleeves 81. The third elastic member 811 is stretched when the auxiliary sleeves 81 move. After printing is completed, the push rod 5 returns to its initial position. The pressing frame 3 returns to its initial position under the action of the first elastic member 43. Simultaneously, the auxiliary sleeve 81 returns to its initial position under the action of the third elastic member 811. After the auxiliary sleeve 81 returns to its initial position, the pressing frame 6 drives the mounting rod 62 back to its initial position, so that the positions of the pressing rod 61 and the auxiliary rod 83 can be adjusted again to fix the plate 01.

[0044] Reference Figure 3 and Figure 4 , a buffer assembly 9 is provided on both the pressing frame 6 and the auxiliary frame 82, the pressing rod 61 is connected to the pressing frame 6 through the buffer assembly 9, and the auxiliary rod 83 is connected to the auxiliary frame 82 through the buffer assembly 9. The connection method of the auxiliary rod 83 and the buffer assembly 9 is the same as the connection method of the pressing rod 61 and the buffer assembly 9. The buffer assembly 9 includes a buffer rod 91 and a fourth elastic member 92, the buffer rod 91 is connected to the end of the pressing rod 61, the buffer rod 91 is slidably arranged on the pressing frame 6 along the vertical direction, the first elastic member 43 can be set as a spring, one end of the spring is connected to the buffer rod 91, and the other end is connected to the pressing frame 6, and the spring is used to drive the buffer rod 91 to move in the direction toward the workbench 1. After the pressing rod 61 and the workbench 1 are in contact, the buffer rod 91 can move relative to the pressing frame 6, reducing the excessive friction between the two when the pressing rod 61 moves relative to the layout 01, which causes damage to the layout 01, thereby protecting the layout 01.

[0045] Reference Figure 3 and Figure 6 The pressing rod 61 is rotatably mounted on the buffer rod 91. The pressing rod 61 is hollow and has a rotating shaft 611 disposed on the buffer rod 91. The pressing rod 61 is rotatably mounted outside the rotating shaft 611. A rotating member 612 is disposed within the pressing rod 61. The rotating member 612 can be configured as a torsion spring, one end of which is connected to the side of the pressing rod 61 and the other end to the rotating shaft 611. When the pressing rod 61 moves relative to the plate 01, the rotating member 612 is rotated and twisted. After the pressing rod 61 unfolds the plate 01, the pressing rod 61 tends to rotate in the opposite direction, placing the plate 01 in a tensioned state and further improving printing quality.

[0046] The implementation principle of this application is: before the hot stamping plate 2 moves to contact the layout 01, the pressing frame 3 and the pressing frame 6 drive the pressing rod 61 to abut against the layout 01. At the same time, under the action of the guide groove 71, after the mounting rod 62 abuts against the layout 01, the mounting rod 62 moves relative to the layout 01, and the layout 01 is unfolded while being fixed. When the hot stamping plate 2 is printing, the layout 01 remains flat, thereby improving the printing quality.

[0047] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
