Description

Technical Field

[0001] The utility model relates to the technical field of impregnated paper, in particular to a drying device for impregnated paper. Background Art

[0002] Impregnated paper, also known as "melamine" paper, is a kind of plain base paper or printed decorative paper that has been impregnated with amino resin (melamine formaldehyde resin and urea-formaldehyde resin) and dried to a certain degree. It has a certain resin content and volatile content. It can be glued to each other or to the artificial board substrate by hot pressing.

[0003] When drying the impregnated paper, the existing method uses hot air direct blowing for drying. This drying method can only dry one side, and the drying efficiency is low. In addition, direct blowing drying will cause the surface of the impregnated paper to shake and produce wrinkles, affecting the quality of the impregnated paper.

[0004] Therefore, we propose a drying device for impregnated paper to solve the above problems. Utility Model Content

[0007] The inner wall of the drying roller is fixedly connected with a heating wire, and the heating wire is in a cylindrical frame shape and is compatible with the inner cavity of the drying roller.

[0008] Preferably, the drying roller is made of a heat-conducting material.

[0009] Preferably, the door panel is made of transparent material.

[0010] Preferably, a heat insulation board is fixedly connected to the surface of the heating plate, and the heat insulation board is made of a heat insulation material.

[0011] Preferably, a plurality of exhaust fans are fixedly connected to the top of the box.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] Start the heating wire and the heating plate. The heating wire heats up and releases heat to transfer the heat to the drying roller. The drying roller is set to a heat-conducting material, which can better transfer heat to the outside, heat and dry the impregnated paper sleeved on the surface of the drying roller, and the heating plate also releases heat to bake the impregnated paper. The heat is heated for drying, and the heat insulation plate fixedly connected to the surface of the heating plate insulates while also ensuring that the heat is used to bake the impregnated paper, which solves the existing method of using hot air direct blowing for drying. This drying method can only dry one side, and the drying efficiency is low. In addition, direct blowing drying will cause the surface of the impregnated paper to shake and produce wrinkles, affecting the quality of the impregnated paper. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-4 The utility model provides a technical solution: a drying device for impregnated paper, comprising a box body 1 and a plurality of mounting frames 2 fixedly connected to the inner cavity of the box body 1, the impregnated paper is inserted into the inner cavity of the box body 1 through a through hole 5 opened on the surface of the box body 1, the impregnated paper is sleeved on a plurality of drying rollers 3 in an S shape, the mounting frame 2 provides support for the drying rollers 3, and the impregnated paper after sleeved is delivered to the outside of the box body 1 through the through hole 5 to be connected to the winding device, a plurality of door panels 9 are hinged on the surface of the box body 1, and the door panels 9 are opened during operation to facilitate the sleeved impregnated paper, and the door panels 9 are set to a transparent material to facilitate the observation of the drying condition of the inner cavity of the box body 1.

[0021] For details, please refer to Figure 1-4 After the impregnated paper is sleeved, the heating wire 7 and the heating plate 4 are started. The heating wire 7 heats and releases heat to transfer the heat to the drying roller 3. The drying roller 3 is set to a heat-conducting material, which can better transfer heat to the outside, and heat and dry the impregnated paper sleeved on the surface of the drying roller 3. The heating plate 4 also releases heat to bake the impregnated paper. The insulation board 8 fixedly connected to the surface of the heating plate 4 insulates while also ensuring that the heat is used to bake the impregnated paper. The water vapor generated during drying is discharged to the outside through the exhaust fan 6 to prevent the water vapor from remaining in the box body 1 and affecting the impregnated paper.

[0022] Working principle: The impregnated paper is delivered to the inner cavity of the box 1 through the through hole 5 opened on the surface of the box 1, and the impregnated paper is sleeved on multiple drying rollers 3 in an S shape. The mounting frame 2 provides support for the drying rollers 3. The impregnated paper after sleeved is delivered to the outside of the box 1 through the through hole 5 and connected to the winding device. Multiple door panels 9 are hinged on the surface of the box 1. During operation, the door panels 9 are opened to facilitate the sleeve connection of the impregnated paper. At the same time, the door panels 9 are set to transparent material to facilitate observation of the drying situation of the inner cavity of the box 1. After the sleeve connection of the impregnated paper is completed, the heating wire 7 and the heating plate 4 fixedly connected to the inner wall of the drying roller 3 are started. The heating wire 7 heats and releases heat to transfer the heat to the drying roller 3. The drying roller 3 The heat conducting material is set to better transfer heat to the outside, and the impregnated paper sleeved on the surface of the drying roller 3 is heated and dried. The heating plate 4 also releases heat to bake the impregnated paper. The heating is dried, and the heat insulation plate 8 fixedly connected to the surface of the heating plate 4 is insulated while also ensuring that the heat is used to bake the impregnated paper. The water vapor generated during drying is discharged to the outside through the exhaust fan 6 to avoid water vapor remaining in the box body 1 and affecting the impregnated paper, thereby solving the problem that the existing method of using hot air direct blowing for drying can only perform single-sided drying, and the drying efficiency is low. In addition, direct blowing drying will cause the surface of the impregnated paper to shake and produce wrinkles, thereby affecting the quality of the impregnated paper.

[0023] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
