Abstract
Description
Technical Field
[0001] This utility model relates to the field of impregnated paper production technology, and in particular to a drying device for impregnated paper production. Background Technology
[0002] Impregnated paper is a functional material made by impregnating base paper with a specific resin or adhesive. It is widely used as a surface veneer in furniture, flooring and other fields. Impregnated paper is mainly made of non-woven wood pulp, polyethylene and plant fibers. This combination gives it super absorbency and resistance to dissolution. It is also an economical and practical low-particle paper towel.
[0003] Impregnated paper production often requires multiple impregnation and drying processes. Drying is generally accomplished using a drying chamber. Existing drying chambers primarily achieve the drying effect by introducing heated air from both sides and venting exhaust gas from the top. However, the air entering from the sides in existing drying chambers results in faster drying at the edges of the impregnated paper and slower drying in the center. This not only leads to uneven drying but also easily causes some areas to have poor drying performance. Therefore, the drying device needs to ensure that the warm, dry airflow contacts the impregnated paper surface better, more evenly, and over a larger area. Furthermore, the exhaust gas contains toxic and harmful gases such as formaldehyde, which require effective adsorption treatment. Utility Model Content
[0004] This invention addresses the shortcomings of existing technologies by providing a drying device for impregnated paper production.
[0005] This utility model is achieved through the following technical solution:
[0006] A drying apparatus for impregnated paper production includes a drying chamber, a cover plate, an air guide hood, an air inlet pipe, a support rod, a paper pressing roller, a mounting rod, a material guiding roller, a filter device, and impregnated paper. The cover plate is installed on one side of the drying chamber. The air guide hood is fixed to the top of the drying chamber. The air inlet pipe is located on the top of the air guide hood. The support rod is fixedly installed on the inner side of the bottom of one end of the drying chamber. The paper pressing roller is movably connected to the top of the support rod. The mounting rod is fixedly installed on both sides of the drying chamber. The material guiding roller is movably connected to the mounting rod. The filter device is located at the back of the drying chamber. The impregnated paper is held inside the drying chamber.
[0007] In a preferred embodiment of the present invention, the filtration device includes a filter shell installed on the back of the drying chamber and an exhaust fan disposed on the back of the filter shell. An adsorption pad is horizontally disposed inside the filter shell, and an air inlet groove is disposed on one side of the drying chamber, on the side connected to the filter shell.
[0008] The filtration device uses an exhaust fan to expel air from inside the drying chamber, and the adsorption pad inside the filter housing decomposes and adsorbs toxic and harmful substances in the exhaust gas, reducing the emission of toxic and harmful gases, thereby protecting the production environment and the health of workers.
[0009] In a preferred embodiment of this utility model, one end of the paper pressing roller is movably connected to the inside of one side of the drying box, the paper pressing roller is horizontally arranged, and the paper pressing rollers inside the drying box are distributed in a W shape.
[0010] The W-shaped pressure rollers allow for longer impregnated paper placement within the drying chamber, thereby increasing the drying stroke and ensuring optimal drying results.
[0011] In a preferred embodiment of the present invention, paper through holes are provided on both sides of the drying box. After the impregnated paper enters from the paper through hole at one end of the drying box, it travels around the surface of the paper pressing roller and then exits from the paper through hole at the other end of the drying box.
[0012] In a preferred embodiment of the present invention, the air guide cover has a herringbone structure, with V-shaped structures at both ends of its bottom. An air outlet is provided at the bottom of the air guide cover, and the air outlet at the bottom of the air guide cover is parallel to the outer surface of the impregnated paper.
[0013] The air guide hood is equipped with multiple air outlets, and the distance between the air outlets and the surface of the impregnated paper is effectively controlled. In addition, the air outlet area is larger, so that the impregnated paper can be effectively dried over a large area and for a long time, thus ensuring the drying effect.
[0014] The beneficial effects of this utility model are:
[0015] This drying device for impregnated paper production increases the travel distance of the impregnated paper within the drying chamber through a W-shaped internal pressing roller. A guide hood further enhances the effect of heated, dry air on the impregnated paper surface, increasing drying time and area for more uniform and comprehensive drying. The resulting exhaust gas is purified by an adsorption device, thus protecting the environment and the health of workers. Attached Figure Description

[0020] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings, so that the advantages and features of this utility model can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of this utility model. The directional terms mentioned in this utility model, such as "up," "down," "front," "back," "left," "right," "top," and "bottom," are only for reference to the accompanying drawings. Therefore, the directional terms used are for the purpose of explaining and understanding this utility model, and not for limiting this utility model.
[0021] like Figure 1-3 The drying device for impregnated paper production shown includes a drying chamber 1, a cover plate 2, an air guide hood 3, an air inlet pipe 4, a support rod 5, a paper pressing roller 6, a mounting rod 7, a material guiding roller 8, a filter device 9, and impregnated paper 10. The cover plate 2 is installed on one side of the drying chamber 1, the air guide hood 3 is fixed to the top of the drying chamber 1, the air inlet pipe 4 is located on the top of the air guide hood 3, the support rod 5 is fixedly installed on the inner side of the bottom of one end of the drying chamber 1, the paper pressing roller 6 is movably connected to the top of the support rod 5, the mounting rod 7 is fixedly installed on both sides of the drying chamber 1, the material guiding roller 8 is movably connected to the mounting rod 7, the filter device 9 is installed on the back of the drying chamber 1, and the impregnated paper 10 is clamped inside the drying chamber 1.
[0022] Specifically, the filter device 9 includes a filter shell 91 installed on the back of the drying chamber 1 and an exhaust fan 92 located on the back of the filter shell 91. An adsorption pad is horizontally arranged inside the filter shell 91. An air inlet groove is provided on one side of the drying chamber 1, connected to the filter shell 91. One end of the paper pressing roller 6 is movably connected to the inside of one side of the drying chamber 1. The paper pressing roller 6 is horizontally arranged. The paper pressing rollers 6 inside the drying chamber 1 are distributed in a W shape. Paper through holes are opened on both sides of the drying chamber 1. After the impregnated paper 10 enters through the paper through hole at one end of the drying chamber 1, it travels around the surface of the paper pressing roller 6 and then exits through the paper through hole at the other end of the drying chamber 1. The air guide hood 3 has a herringbone structure with V-shaped structures at both ends of its bottom. An air outlet is opened at the bottom of the air guide hood 3. The air outlet at the bottom of the air guide hood 3 is parallel to the outer surface of the impregnated paper 10.
[0023] In this embodiment, the impregnated paper 10 is effectively supported at both ends of the drying chamber 1 by the guide rollers 8, so that the impregnated paper 10 will not come into contact with the edges of the paper holes at both ends of the drying chamber 1 during the drying process. After the impregnated paper 10 enters the drying chamber 1, it passes through the surface of the paper pressing roller 6 in sequence, so that it is arranged in a W shape inside the drying chamber 1. The cover plate 2 is easy to open for the paper feeding of the impregnated paper 10. One end of the paper pressing roller 6 is movably connected to the inside of the drying chamber 1, and the other end is movably connected to the support rod 5, so that it is set horizontally.
[0024] Furthermore, during use, an air source is connected to the air inlet pipe 4 at the top of the air guide hood 3. The heated and dried air enters the drying chamber 1. Since the air guide hood 3 has a herringbone structure and its two ends have a V-shaped structure at the bottom, the air outlet area is large and is horizontally set with the surface of the impregnated paper 10, maintaining a constant distance. This ensures that the dried and heated air can better contact the surface of the impregnated paper 10. Long-term, long-stroke, and uniform and effective drying work ensures the drying effect. The exhaust gas generated after drying contains toxic and harmful volatile substances. At this time, the exhaust fan 92 works to extract the internal exhaust gas. When it is discharged, the exhaust gas will pass through the filter shell 91 and be adsorbed and decomposed by the parallel adsorption pads, thereby greatly reducing the harm of the exhaust gas and achieving the effect of protecting the environment and workers' health.
