Abstract
Description
Technical Field
[0001] This utility model belongs to the field of paper production technology, and specifically relates to a drying device for paper production. Background Technology
[0002] In traditional papermaking, papermaking is typically done using a paper-forming screen. After the paper is formed, the wet paper is removed from the screen and stacked together. When the stack reaches a certain height, a pressure plate is placed on top to press out the excess water. Finally, the squeezed-out sheets are separated one by one and then attached to a dryer for further drying. Figure 6 As shown;
[0003] However, when the paper is placed on the heating surface of the dryer, the operator needs to manually smooth the paper with a brush to prevent wrinkles from forming during the drying process. This manual process is inefficient and subject to the limitations of manual skills, which can lead to paper quality problems.
[0004] In view of this, the present invention provides a drying device for paper production to solve the above problems. Utility Model Content
[0005] To achieve the above objectives, the present invention provides the following technical solution: a drying device for paper production, comprising a base and a heating plate disposed on the top surface of the base, wherein the top surface of the heating plate is provided with an adsorption plate for placing paper, and the top surface of the adsorption plate is provided with an array of micropores, wherein the air inlet end of a vacuum adsorption component disposed on one side of the adsorption plate is connected to the micropores, so that when the vacuum adsorption component is running, the paper placed on the top surface of the adsorption plate can be adsorbed flat.
[0006] As a preferred embodiment of the paper production drying device of this utility model, the adsorption plate includes a plate body with an internal cavity, and the micropore array is formed on the top surface of the plate body and communicates with the cavity.
[0007] In a preferred embodiment of the paper drying device of this invention, the air inlet of the vacuum adsorption component is connected to the cavity.
[0008] As a preferred embodiment of the paper drying device of this utility model, the vacuum adsorption component includes a vacuum pump disposed in the base, and the air inlet of the vacuum pump is connected to a vacuum valve and the cavity in sequence through a vacuum pipeline.
[0009] As a preferred embodiment of the paper drying device of this utility model, a vacuum pressure gauge is also installed in the pipeline between the air inlet of the vacuum pump and the vacuum valve.
[0010] As a preferred embodiment of the paper production drying device of this utility model, an infrared heating plate is further provided above the adsorption plate, and the infrared heating plate is connected to the base through a linear drive mechanism.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] 1. This utility model, through the combined arrangement of an adsorption plate and a vacuum adsorption component, allows paper to be placed on the surface of the adsorption plate and then smoothly adsorbed through the numerous micropores arranged in an array on the top surface of the adsorption plate, thus eliminating the need for manual leveling, reducing labor consumption, and improving production efficiency.
[0013] 2. This utility model sets an infrared heating plate above the adsorption plate, which allows short-wave infrared light to quickly penetrate the paper fibers, thereby drying and heating both sides of the paper in conjunction with the heating plate, thus shortening the drying time and further improving the drying efficiency.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] This utility model relates to a drying device for paper production, such as... Figures 1-2 As shown, the device includes a base 1, a heating plate 2 disposed on the top surface of the base 1, a vacuum adsorption assembly 4, and a controller 5 for controlling the operation of the heating plate 2 and the vacuum adsorption assembly 4. The top surface of the heating plate 2 is provided with an adsorption plate 3 for placing paper. The adsorption plate 3 should be made of a material with good thermal conductivity, such as copper, aluminum, or stainless steel, to better transfer the heat generated by the heating plate 2. In this embodiment, the adsorption plate 3 is preferably made of stainless steel. The adsorption plate 3 includes a plate body 31 with an internal cavity 32, and a large number of micropores 33 arranged in an array are formed on the top surface of the plate body 31. Figure 4 As shown, the micropore 33 is connected to the cavity 32 inside the plate 31.
[0024] Specifically, such as Figure 3 As shown, the vacuum adsorption assembly 4 includes a vacuum pump 41 disposed in the base 1. The air inlet of the vacuum pump 41 is connected to the vacuum valve 42 and the cavity 32 in sequence through the vacuum pipeline 43. The vacuum valve 42 can be used to control the on / off and flow rate of the gas in the vacuum adsorption assembly 4, so as to facilitate the adjustment of the vacuum degree according to the characteristics of different papers.
[0025] When in use, the vacuum pump 41 operates to create a negative pressure in the cavity 32, which in turn allows the paper attached to the top surface of the adsorption plate 3 to be adsorbed flat through the micropores 33, replacing the manual leveling step. This also prevents the paper from curling up after drying, keeping the paper flat and dry, and improving the paper quality.
[0026] Furthermore, in order to facilitate operators to monitor the working status of the vacuum adsorption component 4 in real time and ensure that the vacuum level is within the set range, a vacuum pressure gauge 44 can be added to the pipeline between the vacuum pump 41 and the vacuum valve 42.
[0027] Figure 5The second embodiment of this utility model is shown, which differs from the previous embodiment in that an infrared heating plate 6 is also provided above the adsorption plate 3. In this embodiment, the infrared heating plate 6 is a far-infrared heating plate. Far-infrared rays can cause resonance of the molecules in the material, generating heat inside the paper and achieving uniform heating from the inside out. This is very effective in preventing deformation and cracking of the paper due to inconsistent drying speeds inside and outside, and can maintain good physical properties and appearance quality of the paper during the drying process. The infrared heating plate 6 is connected to the base 1 through a linear drive mechanism 7. It should be noted that the operation of the linear drive mechanism 7 and the infrared heating plate 6 is also controlled by the controller 5. In this embodiment, the linear drive mechanism 7 is an electric push rod, but a hydraulic rod can also be used. The distance between the infrared heating plate 6 and the adsorption plate 3 can be adjusted by the operation of the linear drive mechanism 7 to facilitate the operator in laying the paper.
[0028] In use, the infrared heating plate 6 irradiates the top surface of the paper and the heat from the adsorption plate 3 heats the bottom surface of the paper, thus achieving composite heating of the paper, thereby shortening the drying time of the paper and improving production efficiency.
[0029] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
