Description

Technical Field

[0001] The present invention relates to a gilding device, and particularly to a gilding air blowing device. Background Art

[0002] The gilding device is mainly used to gild the aluminum foil on the gilding aluminum foil onto the paper. Its structure mainly includes an upper die table and a lower die table. During operation, the lower die table rises, so that the embossing steel plate on the lower die table cooperates with the gilding plate on the upper die table to press and combine the paper and the aluminum foil for gilding operation. The defect of this structure is that after gilding is completed, the paper is directly moved horizontally by the gripper tooth row, and the paper and the aluminum foil are horizontally separated, resulting in a poor gilding effect. Therefore, there are also some gilding devices with air blowing functions on the market, but the air blowing components are often set far away from the paper and the aluminum foil, and the air blowing separation effect is very limited. Summary of the Invention

[0003] In view of the deficiencies of the background art, the technical problem to be solved by the present invention is to provide a gilding air blowing device with a simple structure, reasonable design, which can first blow and separate the paper and the gilding aluminum foil after gilding is completed, and then drive the paper to be conveyed backward by the gripper tooth row, ensuring the gilding quality.

[0004] To this end, the present invention is implemented as follows:

[0005] A gilding air blowing device has a fixedly arranged upper die table, and a gilding plate is arranged on the upper die table. A lower die table is cooperatively arranged below the upper die table, and an embossing steel plate is arranged on the lower die table. The lower die table is connected to a first lifting drive assembly. It is characterized in that: it further includes a blow pipe, and air blowing heads are arranged at intervals on the blow pipe. The blow pipe is arranged on a lifting seat, and the lifting seat is movably arranged on the lower die table and is connected to a second lifting drive assembly. When the gripper tooth row passes through the upper die table and the lower die table and the lower die table rises for gilding operation, the second lifting drive assembly drives the lifting seat and the blow pipe to rise, so that the air blowing heads are higher than the lower die table. When the lower die table descends, the air blowing heads blow air, and before the gripper tooth row moves, the second lifting drive assembly drives the lifting seat and the blow pipe to descend, so that the air blowing heads are lower than the lower die table.

[0006] The second lifting drive assembly includes a first connecting rod and a second connecting rod. One end of the first connecting rod is hinged to the lifting seat, the other end of the first connecting rod is coaxially hinged to one end of the second connecting rod, the other end of the second connecting rod is hinged to the lower die table, and an extrusion member is connected to the hinge shaft of the first connecting rod and the second connecting rod. A cam cooperating with the extrusion member is arranged on the machine frame, and the lifting seat is connected to an elastic resetting member.

[0007] The elastic resetting member is a spring. One end of the spring is connected to the lifting seat, and the other end is connected to the lower die table.

[0008] A sliding seat is connected to the lifting seat, and a slide rail cooperating with the sliding seat is arranged on the lower die table.

[0009] The pressing member is a bearing.

[0010] For the hot stamping air blowing device of the above technical solution, the air blowing assembly is directly movably arranged on the lower die table and adaptively lifted and lowered along with the lifting and lowering of the lower die table, so that the position of the air blowing assembly is closer to the paper and the aluminum foil, ensuring that the paper can be stably blown away from the gold foil substrate after hot stamping, and then the paper is driven backward by the gripper tooth row for conveying, and the collision with the movement of the gripper tooth row can be avoided, ensuring the quality of hot stamping.

[0014] Figure 3 It is Figure 2 a view from another perspective. Detailed Embodiments

[0015] As shown in the figure, a hot stamping air blowing device disclosed by the present invention has a fixed upper die table 1. A hot stamping plate 20 is arranged on the upper die table 1. A lower die table 2 is arranged in cooperation below the upper die table 1. An embossing steel plate 21 is arranged on the lower die table 2. The lower die table 2 is connected to a first lifting drive assembly. The first lifting drive assembly includes a crank, and the crank is connected to the lower die table 2 through a connecting rod assembly 10 to drive the lower die table 2 to lift. This belongs to the prior art and will not be elaborated here. It further includes a blow pipe 17, which is connected to an air compressor. Air blowing heads 18 are arranged at intervals on the blow pipe 17. The blow pipe 17 is arranged on a lifting seat 13. The lifting seat 13 is movably arranged on the lower die table 2 and is connected to a second lifting drive assembly. When the gripper bar row 5 passes through the upper die table 1 and the lower die table 2 and the lower die table 2 rises for hot stamping operation, the second lifting drive assembly drives the lifting seat 13 and the blow pipe 17 to rise, so that the air blowing heads 18 are higher than the lower die table 2. When the lower die table 2 descends, the air blowing heads 18 blow air, and before the gripper bar row 5 moves, the second lifting drive assembly drives the lifting seat 13 and the blow pipe 17 to descend, so that the air blowing heads 18 are lower than the lower die table 2. In this embodiment, the second lifting drive assembly includes a first connecting rod 16 and a second connecting rod 15. One end of the first connecting rod 16 is hinged to the lifting seat 13. The other end of the first connecting rod 16 is coaxially hinged to one end of the second connecting rod 15. The other end of the second connecting rod 15 is hinged to a connecting rod seat 19 on the lower die table 2. An extrusion member 14 is connected to the hinge axis of the first connecting rod 16 and the second connecting rod 15. A cam 7 cooperating with the extrusion member 14 is arranged on the machine frame 9. The lifting seat 13 is connected to an elastic reset member 6. The elastic reset member is a spring 6. One end of the spring 6 is connected to the lifting seat 13, and the other end is connected to a spring seat 8 on the lower die table 2. Of course, in addition to the above structure, the second lifting drive assembly can also adopt common linear drive components such as cylinders, gear racks, ball screws, and linear motors to control the lifting of the lifting seat 13. A sliding seat 11 is connected to the lifting seat 13. A slide rail 12 cooperating with the sliding seat 11 is arranged on the lower die table 2 to guide the lifting of the lifting seat 13. The extrusion member 14 is a bearing, making the cooperation between the extrusion member 14 and the cam 7 smoother and more reliable.

[0016] The working principle of the present invention is as follows: the aluminum foil 3 is fed between the upper and lower die platforms through the aluminum foil roller 4, and the paper is also pulled between the upper and lower die platforms by the paper gripper row 5, and then the lower die platform 2 rises to press the paper and the aluminum foil between the hot stamping plate 20 and the stamping steel plate 21 to perform the hot stamping operation. At the same time, during the rising process of the lower die platform 2, the extrusion member 14 contacts the cam 7 and drives the first and second connecting rods to move, driving the lifting seat 13, the blowing pipe 17 and the blowing head 18 to rise, so that the blowing head 18 is higher than the lower die platform 2. When the hot stamping is completed, the lower die platform 2 descends, and the paper gripper row 5 also descends together, and the paper and the aluminum foil are pressed between the hot stamping plate 20 and the stamping steel plate 21. The aluminum foil 3 opens an oblique opening, and the blowing head 18 will immediately blow air toward the oblique opening to blow the paper and the aluminum foil 3 apart. As the lower die table 2 continues to descend, the extrusion member 14 separates from the cam 7, and the first and second connecting rods are reset under the action of the elastic reset member 6, driving the lifting seat 13 to descend, so that the blowing head 18 descends and is lower than the lower die table 2, making room for the gripper row 5 to move, and the gripper row 5 can smoothly drive the paper to be transported backward. Such a cyclic action allows the blowing component to avoid the movement law of the gripper row 5, ensuring that the movement of the gripper row 5 will not be interfered with by the blowing component.

[0017] This structure of the present invention directly sets the blowing component movably on the lower die table, and adaptively rises and falls with the rise and fall of the lower die table, so that the position of the blowing component is closer to the paper and the aluminum foil, ensuring that the paper can be stably blown apart from the gold foil substrate after hot stamping, and then the paper is driven backward for transportation by the paper gripper row, and collision with the movement of the paper gripper row can be avoided, thereby ensuring the quality of hot stamping.
