Description

Technical Field

[0001] The present invention relates to the technical field of hot stamping printing, and particularly to a novel wallpaper hot stamping device. Background Art

[0002] With the improvement of people's material and spiritual living standards, people pay more and more attention to the beautification of the surface of books. Traditional printing technologies such as color printing can no longer meet people's needs, so various new printing processes have emerged, and printing machines with different functions have also emerged, such as hot stamping machines. The essence of hot stamping is transfer printing, which is a process of transferring the pattern on the hot stamping tape to the substrate.

[0003] Currently, there are also some hot stamping devices on the market. For example, a hot stamping machine with the Chinese patent publication number CN102092186A includes a substrate conveying device and a hot stamping film conveying device, and a hot stamping device for pressing the hot stamping film on the substrate. The hot stamping device at least includes a first impression roller and a second impression roller that interact with each other. When the two impression rollers work, they can press the hot stamping film and the substrate tightly together, and then transfer the hot stamping film to the substrate.

[0004] However, after hot stamping and laminating with a hot stamping machine such as the above, a drying device is used to dry it. However, during drying, the hot stamping film paper and the substrate are prone to heat expansion. When the composite paper cools down, the base layer and the hot stamping film paper are prone to cold shrinkage, resulting in wrinkles in the hot stamping film paper and affecting the product quality.

Specific embodiments

[0024] The embodiment of the present invention provides a new type of wallpaper bronzing device, as Figures 1-6 shown, including a lower pressing roller 9, an upper pressing roller 10, a base layer, and a bronzing paper 11. The lower pressing roller 9 and the upper pressing roller 10 are used to press the base layer and the bronzing paper 11 into a composite paper 8, and the above technology is the existing technology of the bronzing process.

[0025] This device also includes a base conveyor belt 1, a drying conveyor belt 2, and a cooling conveyor belt 3 for conveying the composite paper 8. The base conveyor belt 1 is an existing conveyor belt, driven by a conveyor belt roller motor. The drying conveyor belt 2 and the cooling conveyor belt 3 are correspondingly arranged above and below the base conveyor belt 1 along the conveying direction, and the drying conveyor belt 2 and the cooling conveyor belt 3 clamp the composite paper 8 on the base conveyor belt 1 for conveying.

[0026] According to the composite paper 8 with different thicknesses and when the composite paper 8 initially passes through the base conveyor belt 1, it is necessary to loosen the drying conveyor belt 2 and the cooling conveyor belt 3 from the base conveyor belt 1 first. Therefore, a clamping assembly 6 for adjusting the distance between them and the base conveyor belt 1 is provided in both the drying conveyor belt 2 and the cooling conveyor belt 3.

[0027] As Figure 1As shown in the figure, a clamping assembly 6 is provided at each end inside each drying conveyor belt 2 or cooling conveyor belt 3. The clamping assembly 6 includes two support wheels 61, an adjusting wheel 62, two connecting rods 63, two telescopic rods 65, a telescopic sleeve 64, and an air pump 66. The middle of the telescopic sleeve 64 is fixed to the frame. The two support wheels 61 and the adjusting wheel 62 are in a triangular shape. The two support wheels 61 and the adjusting wheel 62 support the top, bottom, and side of the conveyor belt respectively. The belt of the conveyor belt meshes with the support wheels 61 and the adjusting wheel 62. The adjusting wheel 62 is hinged to the two support wheels 61 through two connecting rods 63. The two telescopic rods 65 are telescopically connected to the upper and lower ends of the telescopic sleeve 64. The end of the telescopic rod 65 located inside the telescopic sleeve 64 is in a piston-type sealed movable connection with the telescopic sleeve 64, similar to a cylinder. The ends of the two telescopic rods 65 extending out of the telescopic sleeve 64 are respectively hinged to the two support wheels 61. The air pump 66 is arranged on the frame and communicated with the central chamber of the telescopic sleeve 64. When the air pump 66 inflates the telescopic sleeve 64, it can push the two telescopic rods 65 outwards, realizing the expansion of the height of the conveyor belt and clamping it with the base conveyor belt 1. A motor for driving the support wheel 61 can be provided on the telescopic rod 65.

[0028] As Figure 1 and Figure 3 shown in the figure, a drying mechanism 4 for drying is provided inside the drying conveyor belt 2. The drying mechanism 4 includes a support plate 41, a number of drying boxes 42, and a blower 43. A number of drying boxes 42 are fixed on the support plate 41 and arranged in sequence along the conveying direction inside the drying conveyor belt 2. The support plate 41 is fixed on the frame. The blower 43 is communicated with the drying boxes 42 through an air duct 44. Nozzles 45 are provided at the bottom of the drying boxes 42. Electric heating wires 46 are provided inside the drying boxes 42. The blower 43 is used to provide air inside the drying boxes 42. The air is heated by the electric heating wires 46 and the hot air is sprayed from the nozzles 45 towards the belt at the bottom of the drying conveyor belt 2 to heat it.

[0029] As Figure 6 shown in the figure, dense through holes 21 are provided on the drying conveyor belt 2. The adjacent two rows of through holes 21 along the conveying direction are arranged alternately. The hot air passes through the through holes 21 and contacts the composite paper 8 on the base conveyor belt 1, realizing the drying of the composite paper 8 while being clamped by the drying conveyor belt 2.

[0030] A cooling mechanism 5 for cooling is provided inside the cooling conveyor belt 3. The cooling mechanism 5 includes a cooling box 51 which is fixed on the frame. At the front and rear ends of the cooling box 51, there are a box inlet 53 and a box outlet 52 through which the cooling conveyor belt 3 can pass. A nitrogen inlet pipe 54 and a nitrogen outlet pipe 55 through which low-temperature nitrogen can enter are provided on the cooling box 51, and the nitrogen inlet pipe 54 is connected to a nitrogen source. The nitrogen source is a device for manufacturing liquid nitrogen, which is not the protection center of this case. Liquid nitrogen can rapidly cool the cooling conveyor belt 3, and the nitrogen source can also be replaced by other cooling sources. After the belt of the cooling conveyor belt 3 enters the cooling box 51, its temperature drops sharply, and then when it rotates to the bottom and contacts the composite paper 8 on the base conveyor belt 1, heat exchange occurs to cool the composite paper 8.

[0031] During the drying and cooling processes, the drying conveyor belt 2 and the cooling conveyor belt 3 press the composite paper 8 tightly on the base conveyor belt 1 throughout the process. The composite paper 8 completes drying and cooling in the pressed state, preventing the composite paper 8 from wrinkling due to thermal expansion and contraction and improving the product quality.

[0032] To prevent a large amount of nitrogen from leaking out of the cooling box 51, a sealing assembly 7 is provided at the box inlet 53 and the box outlet 52 of the cooling box 51. Specifically, the sealing assembly 7 includes two sets of sealing rollers 71, a telescopic plate 73, and a spring 74. The width of the sealing roller 71 is slightly larger than the width of the composite paper 8. Telescopic cavities 72 are opened at the upper and lower ends of the box inlet 53 or the box outlet 52. The two telescopic plates 73 are telescopically connected in the telescopic cavities 72 respectively. The two sealing rollers 71 are rotatably connected to the ends of the two telescopic plates 73 extending out of the telescopic cavities 72 and are corresponding up and down. The spring 74 is arranged in the telescopic cavity 72, and its upper and lower ends are respectively connected to the top of the telescopic cavity 72 and the telescopic plate 73. The tension of the spring 74 is used to firmly hold the cooling conveyor belt 3 between the two sealing rollers 71. When the vertical width of the cooling conveyor belt 3 is increased or decreased, the upper and lower sealing rollers 71 compress the spring 74, and no matter how the height of the cooling conveyor belt 3 is switched, the sealing rollers 71 can clamp it.

[0033] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
