Description

Technical Field

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0021] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside" and "outside" etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they should not be understood as limitations on the present invention.

[0022] like Figure 1-4 As shown, the utility model is a cold stamping device, comprising an operating table 1, on which two vertical plates 2 are arranged, and a horizontal plate 21 is commonly arranged at the upper ends of the two vertical plates 2, and a cylinder 22 is arranged in the middle of the horizontal plate 21, and a first circular ring 24 is arranged at the output end of the cylinder 22, and a first connecting rod 25 is arranged on the outer side of the first circular ring 24, and a first connecting frame 26 is arranged on the first connecting rod 25, and a cold stamping roller 27 is arranged on the first connecting frame 26, and driven by the cylinder 22, the cold stamping roller 27 is driven to move downward;

[0023] A plate roller 31 is provided directly below the cold stamping roller 27. The plate roller 31 is used in conjunction with the cold stamping roller 27. Both ends of the plate roller 31 are rotatably connected to the operating table 1.

[0024] When in use, the printed product is transported in the direction of the arrow, and the distance between the cold stamping roller 27 and the plate roller 31 is adjusted by the extension and contraction of the cylinder 22, so that it is suitable for cold stamping of printed products of different heights, ensuring the quality of cold stamping, ensuring the clarity of cold stamping patterns, and reducing the scrap rate.

[0025] Preferably, a slide groove 28 is provided on the vertical plate 2, a support rod 29 is provided in the slide groove 28, a motor 30 is installed on the support rod 29, the output shaft of the motor 30 extends the first connecting frame 26 and is connected to the cold stamping roller 27, and driven by the motor 30, the cold stamping roller 27 is driven to rotate; the support rod 29 is provided to support the motor 30, thereby improving the stability of the motor 30, and when the motor 30 is driven, the cold stamping roller 27 is driven to rotate, thereby cold stamping the printed matter.

[0026] In this embodiment, a screw rod 23 is provided at the output end of the cylinder 22, the first ring 24 is sleeved on the bottom end of the screw rod 23, a nut 4 is screwed on the outer side of the screw rod 23, a second ring 41 is rotatably provided on the nut 4, the second ring 41 is sleeved on the outer side of the screw rod 23, a second connecting rod 42 is provided on the outer side of the second ring 41, a second connecting frame 43 is provided on the second connecting rod 42, an upper pressure roller 44 is provided on the second connecting frame 43, a lower pressure roller 45 is provided directly below the upper pressure roller 44, and both ends of the lower pressure roller 45 are rotatably connected to the operating table 1;

[0027] When the cylinder 22 is extended and retracted downward, the cold stamping roller 27 and the upper pressing roller 44 are at the same descending height, and both are in contact with the printed product. After the contact is completed, the nut 4 is rotated to drive the second ring 41 to move downward, thereby driving the upper pressing roller 44 to move downward, so that there is a height difference between the upper pressing roller 44 and the cold stamping roller 27, so that the upper pressing roller 44 can press the printed product;

[0028] The upper pressing roller 44 and the lower pressing roller 45 cooperate with each other to press the printed product. By pressing, the surface of the paperboard is ensured to be flat without protrusions or depressions, which is conducive to the close fit between the cold stamping roller 27 and the surface of the printed product.
