Description

Technical Field

[0001] The utility model belongs to the technical field of glue-impregnated wood-grained paper drying equipment, in particular to a drying device for glue-impregnated wood-grained paper. Background Art

[0002] Wood grain paper is a kind of special paper. It is usually made of kraft paper made of wood pulp as the base paper, and then embossed and dyed on the surface to produce colorful wood grain paper with different patterns. Wood grain paper is used in various fields, especially in the packaging of various products, because of its high ornamental value, strong practicality and high cost performance.

[0003] After searching, the patent announcement number CN210127359U discloses a glue dipping and drying device for wood grain paper production, which belongs to the technical field of wood grain paper glue dipping and drying, including a glue dipping tank, a first motor is installed on one side of the top of the glue dipping tank, the output end of the first motor is connected to a first pulley through a transmission belt, a first leather roller runs through the interior of the first pulley, a first belt is sleeved below the outer surface of the first pulley, a second motor, a rotating shaft, and a scraper are provided. When the wood grain paper after glue dipping is transmitted to the drying chamber through the second leather roller, the wood grain paper will be transmitted between the two scrapers, and because the distance between the two scrapers is fixed and located on both sides of the wood grain paper, at this time, the staff turns on the second motor through the operating table, and the rotation of the second motor drives the rotating shaft to rotate, and the rotation of the rotating shaft drives the scraper to rotate. Under the action of the scraper, more glue adhering to the outer surface of the wood grain paper is scraped off, so that the outer surface of the wood grain board is more uniform, so as to improve the flatness and aesthetics of the wood grain paper.

[0004] After the existing wood grain paper is impregnated with glue and dried, the dried impregnated wood grain paper is directly transported to the outside. The dried impregnated wood grain paper is in a high temperature state. The impregnated wood grain paper in a high temperature state is easy to absorb moisture in the external air environment, which easily causes the impregnated wood grain paper to become damp after drying, affecting the quality of the impregnated wood grain paper after drying. At this time, we propose a drying device for wood grain paper impregnation to solve the existing problems. Utility Model Content

DETAILED DESCRIPTION

[0028] 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.

[0029] See also Figures 1 to 9The utility model of the drying device for wood grain paper impregnation mainly comprises a shell 1: the front end wall of the shell 1 is provided with a sealing door A4 and a sealing door B6, the rear end wall of the sealing door A4 and one side of the rear end wall inside the shell 1 are both installed with a high-frequency medium heater 16, a guide roller 17 is installed inside the shell 1, and a limit plate 18 is installed above and below the outer wall of the guide roller 17, a connecting shaft 2 is installed at the top and bottom center positions of the guide roller 17, and the other ends of the connecting shaft 2 on the top and bottom ends of the guide roller 17 are respectively installed on the sealing bearing on the top end of the shell 1 and the inner bearing on the bottom end of the shell 1, and the other side of the rear end wall of the shell 1 and the front end wall of the sealing door are A second box body 9 is installed, a plate-type activated carbon filter 27 and a second exhaust fan 26 are installed inside the second box body 9, and the second exhaust fan 26 is located at the front end or rear end of the plate-type activated carbon filter 27. A first box body 11 is installed on one side of the top and bottom ends of the shell 1, a first exhaust fan 23 and a plate-type air filter 22 are installed inside the first box body 11, and the first exhaust fan 23 is located above or below the plate-type air filter 22. When the utility model dries the wood-grained paper after the impregnation is completed, the staff makes the impregnated wood-grained paper in the conveying state enter from the wood-grained paper inlet and outlet slot 3 on the outer wall of one side of the shell 1 and exit from the wood-grained paper on the outer wall of the other side of the shell 1. The wood grain paper enters and exits the slot 3 for output. During the transportation of the impregnated wood grain paper inside the shell 1, the high-frequency medium heater 16 converts ordinary power into a high-frequency electric field. The electric field can penetrate the glue. The water molecules in the glue will absorb the high-frequency electric field, polarize themselves, and generate heat through the rapid friction between molecules. Therefore, the high-frequency heating method is that the heat generated by the water itself is different from the heat conduction method of steam or electric heating. Therefore, the part with more water absorbs more high-frequency energy, so that the glue can be heated quickly to achieve rapid curing of the glue. When the impregnated wood grain paper continues to be transported after drying, the first exhaust fan 23 and the second exhaust fan 26 are started. The first exhaust fan 23 is started to output external cold air The air is sent to the inside of the shell 1, and the air flow formed by the first exhaust fan 23 above and below the Y-axis direction of the utility model will produce a certain collision. The second exhaust fan 26 is started to discharge the air inside the shell 1 to the outside. During the above air flow process, the impregnated wood grain paper in a high-temperature state after drying can be effectively cooled down. Therefore, the utility model can quickly cool the impregnated wood grain paper after drying, avoiding the situation where the impregnated wood grain paper in a high-temperature state after drying contacts with the external air environment, causing moisture in the air to be adsorbed onto the glue wood grain paper in a high-temperature state after drying, thereby improving the quality of the impregnated wood grain paper after drying.
