[0026] Reference Figures 1-4 A dehydration device for preparing white cardboard includes a base plate 1, white cardboard 3, and a dehydration mechanism 4;

[0027] A dewatering box 2 is provided on the base plate 1. One end of the white cardboard 3 passes through the dewatering box 2. Two dewatering mechanisms 4 are provided on the dewatering box 2. The two dewatering mechanisms are located on both sides of the white cardboard 3 and are connected to the white cardboard 3. A winding mechanism (not shown in the figure) is provided on the base plate 1. One end of the white cardboard 3 is connected to the winding roller on the winding mechanism. The dewatered white cardboard 3 can be wound up by the winding structure. The winding mechanism is a conventional structure in this field and belongs to the prior art. It can be implemented by those skilled in the art and will not be described in detail.

[0028] The dehydration mechanism 4 includes a cylinder 41, a housing 42, a heating grid 43, a scraper 44, an industrial vacuum cleaner 45, a filter box 46, and a round tube 47. The dehydration box 2 has two housings 42, which are located on both sides of the white cardboard 3. The heating grid 43 is fixedly installed inside the housing 42 and corresponds to the white cardboard 3. Multiple scrapers 44 are fixedly connected to the upper part of the heating grid 43 and are in contact with the white cardboard 3. Through the coordinated design of the dehydration box 2, the cylinder 41, the heating grid 43, the scraper 44, the industrial vacuum cleaner 45, and the control panel 5, not only can the white cardboard 3 be dehydrated, but also impurities on the surface of the white cardboard 3 can be effectively cleaned and collected, thus improving product quality.

[0029] In this embodiment, two cylinders 41 are fixedly installed on the housing 42. Both cylinders 41 are fixedly connected to the dewatering box 2 and are used to move and adjust the two housings 42, thereby facilitating the dewatering of white cardboard 3 of different specifications.

[0030] In this embodiment, an industrial vacuum cleaner 45 is fixedly installed on the dehydration tank 2. One end of the industrial vacuum cleaner 45 is sealed with a flexible hose, and one end of the flexible hose is sealed with the housing 42. It is used to suck up the impurities cleaned by multiple scrapers 44. One end of the industrial vacuum cleaner 45 is sealed with a conveying pipe, and one end of the conveying pipe is sealed with a filter box 46. The filter box 46 is fixedly connected to the dehydration tank 2. A dehumidifying filter plate is installed inside the filter box 46 to filter water vapor in the hot air. One side of the filter box 46 is sealed with a round pipe 47. One end of the round pipe 47 is sealed with the dehydration tank 2 and extends into the dehydration tank 2 to transport the filtered hot air into the dehydration tank 2, thereby increasing the temperature inside the dehydration tank 2 and further improving the dehydration effect on the white cardboard 3.

[0031] In this embodiment, a control panel 5 is fixedly installed on the dehydration tank 2. The two cylinders 41, the industrial vacuum cleaner 45 and the heating grid 43 are all connected to the control panel 5. The control panel 5 drives and controls the cylinders 41, the industrial vacuum cleaner 45 and the heating grid 43.

[0032] In this embodiment, multiple scrapers 44 are arranged at equal intervals on the heating grid 43. All scrapers 44 are thermally conductive. As a result, through the heat transfer between the heating grid 43 and the multiple scrapers 44, one side of the scraper 44 irons the white cardboard 3, making the paper smoother.

[0033] In this embodiment, the two dehydration mechanisms 4 are symmetrical to each other.

[0034] Working principle: During use, the cylinder 41, industrial vacuum cleaner 45 and heating grid 43 are driven and controlled through the control panel 5;

[0035] First, one end of the white cardboard 3 is passed through the dehydration box 2 and connected to the winding mechanism. Then, the housing 42 drives the heating net 43 to clamp onto the white cardboard 3 and make multiple scrapers 44 contact the white cardboard 3. After that, the heating net 43 and the industrial vacuum cleaner 45 are used.

[0036] The heating wire 43 heats and dries the white cardboard 3. Meanwhile, since the multiple scrapers 44 are thermally conductive, heat transfer between the heating wire 43 and the multiple scrapers 44 allows one side of the scrapers 44 to iron the white cardboard 3, making the paper smoother. This further heats and dries the white cardboard 3. At the same time, the multiple scrapers 44 can scrape and clean impurities on the surface of the white cardboard 3, reducing impurities on the surface of the white cardboard 3 after dehydration and improving cleanliness and product quality.

[0037] Driven by the industrial vacuum cleaner 45 and utilizing the hose and housing 42, impurities removed by multiple scrapers 44 are sucked up and collected. Simultaneously, it absorbs water vapor generated during the dehydration of the white cardboard 3. The hot air, still containing water vapor, is then discharged through a conveying pipe into the filter box 46. Here, the dehumidifying filter plate within the filter box 46 filters the water vapor. The filtered hot air is then discharged through a circular pipe 47 into the dehydration chamber 2, raising the temperature within the dehydration chamber 2 and further enhancing the dehydration effect on the white cardboard 3.

[0038] The technological advancements of this invention compared to existing technologies are as follows: through the cooperation of various components, not only can the white cardboard 3 be dehydrated, but also impurities on the surface of the white cardboard 3 can be cleaned and collected, thus improving product quality. Moreover, the structure is simple and the practicality is higher.
