Technical Field

[0001] This invention relates to the field of paper processing technology, and more specifically to paper hot stamping apparatus and paper hot stamping method. Background Technology

[0002] The equipment used to transfer part of the colorant (hot foil layer or electroplated layer) on hot foil (electroplated aluminum foil) onto paper to form a pattern on the paper is a hot foil stamping device.

[0003] The hot stamping apparatus includes a main body, which includes a frame with a hot stamping station. A hot stamping assembly is mounted on the side of the hot stamping station, enabling hot stamping of paper. The frame houses a hot stamping paper roller, a base paper roller, a product paper roller, and a waste paper roller. In use, hot stamping paper (i.e., colored paper) is mounted on the hot stamping roller, the paper to be hot stamped is mounted on the base paper roller, and the paper to be hot stamped is wound onto the product paper roller. For products with patterns, the waste paper (i.e., scraps of hot stamping paper with some color removed) is wrapped around the waste paper roller. The path of the hot stamping paper from the hot stamping paper roller to the hot stamping station is the hot stamping paper travel route. The path of the paper to be hot stamped from the raw paper roller to the hot stamping station is the paper travel route. The path of the hot stamped product from the hot stamping station to the product roller is the product route. The path of the hot stamping paper from the hot stamping station to the waste paper roller after use is the waste paper collection route.

[0004] In the existing technology, there are no pre-treatment components on the paper travel path of the hot stamping device. As a result, the paper for hot stamping is not treated, and the pigment cannot adhere well to the paper. During use, the pigment is prone to falling off, and the quality of hot stamping cannot be guaranteed. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned shortcomings by providing a paper hot stamping device and method that ensures the ink does not easily fall off and improves product quality.

[0006] The technical solution of the paper hot stamping device of the present invention is implemented as follows: The paper hot stamping device includes a device body, which includes a device frame. A hot stamping station is located on the device frame, and a hot stamping assembly is installed on the side of the hot stamping station. The hot stamping assembly can perform hot stamping on paper. A hot stamping paper roller, a base paper roller, a product roller, and a waste paper roller are installed on the device frame. In use, hot stamping paper is installed on the hot stamping paper roller, the paper to be hot stamped is installed on the base paper roller, the product roller is wrapped with the hot stamped product with a pattern, and the waste paper roller is wrapped with the remaining paper after the hot stamping paper has been used. The path that the hot stamping paper takes from the hot stamping paper roller to the hot stamping station is the hot stamping paper travel route. The path of the paper to be hot-stamped from the base paper roller to the hot-stamping station is the paper travel route. The path of the hot-stamped product from the hot-stamping station to the product roller is the product route. The path of the hot-stamped paper from the hot-stamping station to the waste paper roller after use is the waste paper collection route. Its characteristic is that there is also a humidification chamber installed on the device frame. The humidification chamber has a humidification chamber inlet and a humidification chamber outlet. The paper travel route passes through the humidification chamber inlet and the humidification chamber outlet. It also includes a humidifier with a moisture outlet that leads to the humidification chamber. The humidifier can make the humidity in the humidification chamber reach 80-85%, and the humidity of the paper after passing through the humidification chamber reaches 5-8%.

[0007] Furthermore, a heating device and a temperature measuring device are installed in the humid chamber. The heating device and the temperature measuring device are connected to a control device. The temperature measuring device transmits the measured temperature to the control device, which controls the degree of activation of the heating device. The control device can make the temperature in the humid chamber reach 50-60°C.

[0008] Furthermore, multiple pairs of pressing rollers are installed in the humid chamber, and the paper travels through the pressing rollers, so that the paper is subjected to a pressing force of 1 to 1.2 kg / cm².

[0009] Furthermore, a drying chamber is installed on the device frame. The drying chamber has a drying chamber inlet and a drying chamber outlet. The product route passes through the drying chamber inlet and the drying chamber outlet. It also includes a dryer with a drying gas outlet that leads to the drying chamber. The dryer can make the humidity in the drying chamber reach 20-25%.

[0010] Furthermore, the humidity in the humid room differs from that in the dry room by at least 50%.

[0011] The technical solution of the paper hot stamping device of the present invention is implemented as follows: the raw materials used are hot stamping paper and paper to be hot stamped. Before hot stamping, the paper needs to be moistened so that the moisture content of the paper reaches 5-8%. This process is the paper moistening process. The water used to moisten the paper during the paper moistening process is moistening water.

[0012] Furthermore, during the paper wetting process, the temperature of the paper is 50-60℃.

[0013] Furthermore, the wetting water used in the paper wetting process also contains acetic acid, and the pH of the wetting water is 5.3-5.5.

[0014] Furthermore, during the process of the paper becoming wet, it is also subjected to rolling pressure, which reaches 1 to 1.2 kg / cm².

[0015] Furthermore, after the paper is hot-stamped, it needs to be dried immediately.

[0016] The beneficial effects of this invention are that such a paper hot stamping device and paper hot stamping method have the advantages of making the hot stamped product color less likely to fall off and improving product quality. Attached Figure Description

[0021] The technical solution of the present invention will be further described below with reference to the embodiments.

[0022] like Figure 1 , 2As shown in Figure 3, the paper hot stamping device includes a device body, which includes a device frame 1. A hot stamping station 2 is located on the device frame, and a hot stamping assembly 21 is installed on the side of the hot stamping station. The hot stamping assembly can perform hot stamping on paper. Hot stamping paper roller 3, base paper roller 4, product roller 5, and waste paper roller 6 are installed on the device frame. In use, hot stamping paper is installed on the hot stamping paper roller, the paper to be hot stamped is installed on the base paper roller, the product roller is wrapped with a patterned product formed by hot stamping, and the waste paper roller is wrapped with the remaining waste paper after the hot stamping paper has been used. The path of the hot stamping paper from the hot stamping paper roller to the hot stamping station is the hot stamping paper travel path 31. The paper to be hot stamped starts from the base paper roller and travels along the base paper roller. The path from the paper roller to the hot stamping station is the paper travel route 41. The path from the hot stamping station to the product roller after the hot stamping is intact is the product route 51. The path from the hot stamping station to the waste paper roller after the hot stamping paper has been used is the waste paper collection route 61. Its characteristic is that there is also a humidification chamber 7 installed on the device frame. The humidification chamber has a humidification chamber inlet 71 and a humidification chamber outlet 72. The paper travel route passes through the humidification chamber inlet and the humidification chamber outlet. It also includes a humidifier 73. The humidifier has a moisture outlet 74. The moisture outlet leads to the humidification chamber. The humidifier can make the humidity in the humidification chamber reach 80-85%. The humidity of the paper after passing through the humidification chamber reaches 5-8%.

[0023] The paper hot stamping apparatus of the present invention first moistens the paper before hot stamping, so that the paper has a certain degree of humidity. During the hot stamping process, the pigment is more likely to adhere to the paper, thus achieving the purpose of the present invention.

[0024] When in use, the humidifier uses an aqueous solution containing acetic acid, which makes the pattern on the hot stamping foil adhere more firmly to the paper.

[0025] Furthermore, a heating device 75 and a temperature measuring device 77 are installed in the humid chamber. The heating device and the temperature measuring device are connected to a control device. The temperature measuring device transmits the measured temperature to the control device, which controls the degree of activation of the heating device. The control device can make the temperature in the humid chamber reach 50-60°C.

[0026] This invention is designed to improve the hot stamping effect on paper, for example, to make the hot stamping layer adhere more firmly to the paper.

[0027] Furthermore, multiple pairs of pressing rollers 76 are installed in the humid chamber, and the paper travels through the pressing rollers, so that the paper is subjected to a pressing force of 1 to 1.2 kg / cm².

[0028] This invention, with its specific configuration, allows for a better hot stamping effect on the paper; for example, it ensures that the hot stamping layer adheres more firmly to the paper. To enable the operation of the pressing roller, a pressing motor is naturally connected to it.

[0029] Furthermore, a drying chamber 8 is installed on the device frame. The drying chamber has a drying chamber inlet 81 and a drying chamber outlet 82. The product route passes through the drying chamber inlet and the drying chamber outlet. It also includes a dryer 83, which has a drying gas outlet 84 that leads to the drying chamber. The dryer can make the humidity in the drying chamber reach 20-25%.

[0030] This design allows for better hot stamping results, for example, making the hot stamping layer adhere more firmly to the paper. All of the above configuration is sufficient to ensure that the drying chamber has dry air.

[0031] Furthermore, the humidity in the humid room differs from that in the dry room by at least 50%.

[0032] This method of obtaining hot stamping foil ensures better integrity of the design even after a long period of time.

[0033] Example 1 The raw materials used are hot stamping foil and the paper to be hot stamped. Before hot stamping, the paper needs to be moistened so that the paper's moisture content reaches 5-8%. This process is called paper moistening. The water used to moisten the paper during the paper moistening process is called moistening water.

[0034] The resulting hot stamping foil is the first hot stamping foil.

[0035] Example 2 Repeat Example 1 above, and during the paper wetting process, the temperature of the paper is 50-60°C.

[0036] The resulting hot stamping foil is the second type of hot stamping foil.

[0037] Example 3 Repeat Example 2 above, and in the process of wetting the paper, the wetting water also contains acetic acid, and the pH of the wetting water is 5.3 to 5.5.

[0038] The resulting hot stamping foil is the third type of hot stamping foil.

[0039] Example 4 Repeat Example 3 above, and during the process of the paper being moistened, the paper is also subjected to rolling pressure of 1 to 1.2 kg / cm².

[0040] The resulting hot stamping foil is the fourth type of hot stamping foil.

[0041] Example 5 Repeat Example 4 above, and after the paper is hot-stamped, it needs to be dried immediately.

[0042] The resulting hot stamping foil is the fifth type of hot stamping foil.

[0043] After testing, the integrity of the patterns remained better over a long period of time with the first, second, third, fourth, and fifth hot foil stamping foils, indicating that the quality was better in that order.

[0044] It should be noted that the above-described paper hot stamping apparatus and paper hot stamping method embodiments, beneficial effects, etc., can be explained and interpreted by each other.

[0045] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
