[0023] The embodiment of the present application provides an indentation adjustment device for a hot stamping machine. Refer to Figures 1 to 2 , including:

[0024] A cylinder 1, an adjustment device, a mounting table 2, and a connecting plate 3. Among them,

[0025] The cylinder 1 is installed on the mounting table 2, and the piston rod 4 of the cylinder 1 extends downward through the mounting table 2 and is connected to the rotating shaft of the hot stamping roller 15;

[0026] The adjusting device is installed on the mounting table 2 and includes: a slider 5, a fixed block 6, an adjusting screw 7, and an adjusting rod 8. The fixed block 6 is fixedly connected to the mounting table 2. The fixed block 6 includes a bearing portion 9 and an adjusting portion 10. The upper surface of the bearing portion 9 is an inclined surface. The slider 5 is disposed above the bearing portion 9, and the upper surface of the bearing portion 9 abuts against the lower surface of the slider 5. A first opening 11 is horizontally formed in the adjusting portion 10. The adjusting screw 7 passes through the first opening 11 and is threadedly connected to the side wall of the slider 5. A second opening 12 is vertically formed in the slider 5. The adjusting rod 8 passes through the second opening 12 and extends downward through the bearing portion 9. A protrusion is provided at the upper end of the adjusting rod 8, and the diameter of the protrusion is larger than the diameter of the second opening 12.

[0027] The connecting plate 3 is located below the mounting table 2 and is fixedly connected to the adjusting rod 8 and the piston rod 4 respectively.

[0028] Specifically, the adjusting screw 7 passes through the first opening 11 of the fixed block 6 and is threadedly connected to the side wall of the slider 5. By rotating the adjusting screw 7, the position of the slider 5 on the inclined surface can be precisely controlled. For example, when the adjusting screw 7 is rotated clockwise, the adjusting screw 7 is screwed into the slider 5, and due to the blocking of the nut, the slider 5 is driven to move obliquely downward in the direction of the adjusting screw 7, and the height position of the slider 5 is lowered; conversely, the height position of the slider 5 is raised. A protrusion is provided at the upper end of the adjusting rod 8, and the diameter of the protrusion is larger than the diameter of the second opening 12 to limit the downward movement stroke of the adjusting rod 8 and prevent the adjusting rod 8 from falling off the slider 5. By adjusting the height position of the slider 5, the limit of the downward movement stroke of the adjusting rod 8 can be adjusted. When the height position of the slider 5 is lowered, the up and down movement stroke of the adjusting rod 8 increases; conversely, the up and down movement stroke of the adjusting rod 8 decreases.

[0029] Specifically, the connecting plate 3 is located below the mounting table 2 and is fixedly connected to the adjusting rod 8 and the piston rod 4 respectively. By adjusting the position of the slider 5 through the adjusting device, the stroke of the adjusting rod 8 is changed, and finally, the precise adjustment of the stroke of the piston rod 4 is achieved through the connecting plate 3. By adjusting the stroke of the piston rod 4, the magnitude of the pressure transmitted by the piston rod 4 to the hot stamping roller 15 can be realized, so as to achieve the precise control of the hot stamping indentation.

[0030] In some embodiments, a bearing 13 is sleeved on the rotating shaft of the hot stamping roller 15, and the lower end of the piston rod 4 is connected to the outer ring of the bearing 13.

[0031] Specifically, the cylinder 1 is installed on the mounting table 2, and its piston rod 4 penetrates through the mounting table 2 and is connected to the rotating shaft of the hot stamping roller 15 through a bearing 13. This connection method ensures that the movement of the piston rod 4 can be directly transmitted to the hot stamping roller 15, achieving precise control of the indentation. A bearing 13 is sleeved on the rotating shaft of the hot stamping roller 15, and the lower end of the piston rod 4 is connected to the outer ring of the bearing 13. This connection method reduces friction and wear, and improves the accuracy and stability of adjustment.

[0032] In some embodiments, the diameter of the first opening 11 is larger than the diameter of the adjusting screw 7;

[0033] The diameter of the second opening 12 is larger than the diameter of the adjusting rod 8.

[0034] Specifically, the diameter of the first opening 11 being larger than the diameter of the adjusting screw 7 can leave space for the up and down movement of the adjusting screw 7, so that the slider 5 can achieve an oblique up and down movement; the diameter of the second opening 12 being larger than the diameter of the adjusting rod 8 can leave space for the oblique movement of the slider 5.

[0035] In some embodiments, the mounting table 2 is fixedly connected to the wall panel 14.

[0036] Specifically, the mounting table 2 and the wall panel 14 are firmly connected by bolts or other fixing parts to ensure the stability and safety of the entire device during operation.

[0037] In some embodiments, a guide rail is sleeved on the piston rod 4, and one end of the guide rail is fixedly connected to the wall panel 14.

[0038] Specifically, a guide rail is sleeved on the piston rod 4, and one end of the guide rail is fixedly connected to the wall panel 14. The design of the guide rail helps to guide the movement trajectory of the piston rod 4 and improves its movement accuracy and stability.

[0039] In some embodiments, the guide rail is of a long strip structure, and its length is determined according to the actual needs of the hot stamping machine indentation adjustment device. The cross-sectional shape of the guide rail is usually "T" - shaped or "U" - shaped. Among them, the top surface of the "T" - shaped guide rail contacts the lower surface of the piston rod 4 to provide support and guiding functions; the "U" - shaped guide rail contacts the piston rod 4 through the side walls on both sides to achieve the same effect. The width and height (or depth) of the guide rail are determined according to the diameter of the piston rod 4 and the required support stability. Usually, the width of the guide rail is slightly larger than the diameter of the piston rod 4 to ensure that the piston rod 4 can move smoothly in the guide rail. One end of the guide rail is firmly connected to the wall panel 14 by bolts or other fixing parts to ensure the stability of its position and its immobility. The other end of the guide rail can be designed with a stop device, such as a stop block or a limit screw, to prevent the piston rod 4 from moving excessively in the guide rail.

[0040] In summary, compared with the prior art, the hot stamping machine indentation adjustment device provided by the above technical solution can adjust the height position of the slider 5 in the adjustment device, thereby adjusting the stroke of the up and down displacement of the adjusting rod 8. Through the fixing effect of the connecting plate 3, the stroke of the piston rod 4 is made consistent with the stroke of the adjusting rod 8, thereby realizing the adjustment of the stroke of the piston rod 4. When the slider 5 moves obliquely downward, the stroke of the piston rod 4 increases, the pressure of the piston rod 4 on the hot stamping roller 15 increases, and the hot stamping indentation also increases. On the contrary, the hot stamping indentation decreases. This solves the problem that when the prior art hot stamping device performs hot stamping on printed matter, the hot stamping device will perform hot stamping straight up and down, and it is difficult to adjust the size of the hot stamping indentation.
