Description

Technical Field

[0001] The utility model belongs to the field of hot stamping, and particularly relates to a hot stamping device. Background Art

[0002] Hot stamping is a special printing process that does not use ink. Hot stamping refers to the process of hot stamping electrochemical aluminum foil onto the surface of the substrate under a certain temperature and pressure.

[0003] In the existing hot stamping devices, the structural design is mostly that the winding structure and the unwinding structure are respectively located on both sides thereof, and the hot stamping structure is located in the middle of the unwinding structure and the winding structure; however, when replacing the printing material with this structure, the workers have to disassemble and assemble the printing material wound by the winding structure and the printing material unwound on the unwinding structure at both sides of the frame respectively, and this operation is relatively troublesome and the replacement efficiency is low; and in the existing hot stamping device, based on the limitations of the winding structure and the unwinding structure on both sides thereof, it is not convenient to further expand the functional structure.

[0004] For example, a 3D round hot stamping device disclosed in a prior patent (application number CN201720244762.5) includes a first frame, a second frame, a third frame, and a fourth frame connected in sequence, an unwinding unit arranged on the first frame, a printing unit arranged on the second frame, a round hot stamping unit arranged on the third frame, and a rewinding unit arranged on the fourth frame, and the round hot stamping unit includes a first unwinder arranged on one side of the upper end of the round hot stamping unit, a first rewinder arranged on the other side of the upper end of the round hot stamping unit, and a round hot stamping structure arranged below the midpoint of the center connection line between the first unwinder and the first rewinder. This device has the above-mentioned defects of the prior art. Utility Model Content

[0005] In order to solve the above problems, the technical purpose of the utility model is to provide a hot stamping device, in which the printing material unwinding component and the printing material winding component are located on the same side, which makes it more convenient, faster and more efficient to replace the printing material.

[0006] Another technical purpose of the utility model is to provide a hot stamping device, which is convenient for further expanding the functional structure and making it more convenient to use.

[0007] In order to achieve the above-mentioned purpose, the technical solution of the utility model is as follows.

[0008] A hot stamping device, characterized in that the hot stamping device comprises:

[0009] A reeling and unreeling mechanism, the reeling and unreeling mechanism comprising a printing material unreeling assembly for unreeling the printing material and a printing material reeling assembly for reeling the printing material;

[0010] A digital printing mechanism for printing on a substrate;

[0011] A hot stamping mechanism for hot stamping the printing material;

[0012] The frame, the digital printing mechanism is arranged on the upper side of the frame, and the unwinding and rewinding mechanism and the hot stamping mechanism are respectively arranged on the left and right sides of the frame; the printing material unwinding component to the digital printing mechanism to the hot stamping mechanism and then to the printing material winding component forms a processing path for digital printing and hot stamping of the printing material.

[0013] In the hot stamping device, when it is processed, the printing material is first unwound by the unwinding component, the printing material is digitally printed by the digital printing mechanism, and then hot stamped by the hot stamping mechanism, and finally rewound by the rewinding component to complete the digital printing and hot stamping processing of the printing material in the processing path; and in the hot stamping device, the unwinding component and the rewinding component are arranged on the same side of the frame, when it is necessary to disassemble and assemble the printing material rewound by the rewinding component and the printing material unwound on the unwinding component, the worker can complete the work at the same position, and the disassembly and assembly process is more convenient, faster and more efficient. And because the unwinding component and the rewinding component are both located on one side of the frame, it is more convenient to further expand and install the functional structure on the other side of the frame as needed.

[0014] Furthermore, the device also includes a corona component and a deflection correction component, and the processing path enters the digital printing mechanism after passing through the corona component and the deflection correction component from the printing material unwinding component. The corona component and the deflection correction component are used to perform corona and deflection correction treatment on the printing material before digital printing by the digital printing mechanism.

[0015] Furthermore, there are two printing material winding assemblies, which are respectively arranged on the left and right sides of the printing material unwinding assembly; the processing path is from the hot stamping mechanism to any one of the two printing material winding assemblies. The two printing material winding assemblies can be arranged so that different printing material winding assemblies can be selected for winding as needed. The printing material winding assembly located on the side of the printing material unwinding assembly close to the hot stamping mechanism can be used to wind up a relatively small amount of printing material, and the printing material winding assembly located on the other side of the printing material unwinding assembly away from the hot stamping mechanism can be used to wind up a relatively larger amount of printing material.

[0016] Furthermore, the hot stamping mechanism includes a hot stamping film winding assembly, a hot stamping film unwinding assembly, and a hot stamping assembly. The hot stamping film winding assembly and the hot stamping film unwinding assembly are both arranged on the upper side of the frame. The unwinding mechanism and the hot stamping assembly are arranged on the left and right sides of the frame respectively. The processing path passes through the hot stamping assembly. The hot stamping film unwinding assembly, the hot stamping assembly, and the hot stamping film winding assembly form a hot stamping film path. The hot stamping film unwinding from the hot stamping film unwinding assembly passes through the hot stamping assembly, and the printing material passing through the hot stamping assembly is hot stamped, and finally the hot stamping film winding assembly is rewound.

[0018] A cooling roller assembly cooperates with a cold stamping roller assembly and a hot stamping roller assembly, so that it can be used for both cold stamping and hot stamping. When used for cold stamping, the cold stamping roller assembly is driven by the cold stamping driving assembly to approach the cooling roller assembly to control the cold stamping gap distance to meet the stamping distance, and at the same time, the hot stamping driving assembly drives the hot stamping roller assembly to approach the cooling roller assembly and away from the cooling roller assembly. At this time, the stamping film passes through the cold stamping gap to cooperate with the cold stamping roller assembly and the cooling roller assembly to perform cold stamping on the printing material. If hot stamping is required, the above process is reversed. Based on the structural design of the mechanism, when it is used on a stamping device, the size of the stamping device can be avoided to be too large and the cost can be reduced.

[0019] Furthermore, the cooling roller assembly is a water-cooled roller assembly.

[0020] Furthermore, the hot stamping roller assembly is located below the cooling roller assembly, and the cold stamping roller assembly is located obliquely above the cooling roller assembly.

The cold stamping driving assembly includes a cylinder, which is fixed on the cold stamping roller bracket and is in transmission connection with the cold stamping movable blocks.

[0023] Furthermore, the cold stamping drive assembly includes two cylinders, which are respectively fixed on two cold stamping roller brackets, and the two cylinders are respectively connected to the two cold stamping movable blocks in a transmission manner.

The hot stamping drive assembly drives the hot stamping roller bracket to rotate around one end thereof to drive the hot stamping roller to approach or move away from the cooling roller assembly.

[0025] Further, the hot stamping drive assembly includes a drive member, a hot stamping movable block, and a hot stamping transmission member, wherein the drive member is fixedly arranged on the frame, the drive member is in transmission connection with the hot stamping movable member, so as to drive the hot stamping movable member to reciprocate, the hot stamping transmission member is fixedly arranged on the hot stamping movable block, and the hot stamping transmission member is provided with a transmission inclined surface for driving the hot stamping roller bracket to rotate, and the other end of the hot stamping roller bracket is movably supported on the transmission inclined surface.
