Description

Technical Field

[0001] The utility model relates to an air drying device, in particular to a melamine impregnated paper glue impregnation air drying device, belonging to the technical field of paper processing. Background Art

[0002] The full name of melamine impregnated paper is melamine impregnated adhesive paper. It is a kind of adhesive paper with a certain resin content and volatile content that is made of plain base paper or printed decorative paper impregnated with amino resin and dried to a certain degree. It can be glued to each other or to the artificial board substrate after hot pressing. Melamine impregnated paper needs to be impregnated with glue during the processing process. After the impregnation is completed, it needs to be quickly air-dried to facilitate subsequent operations. Quick air-drying requires the use of an air-drying device.

[0003] A rapid air-drying device for book and periodical printing is disclosed in the Chinese patent application publication specification CN218838962U, in which an exhaust mechanism drives air to flow from top to bottom through the through holes on the upper end surface of the upward section of the conveyor belt, so that the paper prints are adsorbed on the conveyor belt, thereby improving the problem that the paper is easily displaced under the action of the flowing air during the air-drying process. The air blown out of the air outlet pipe is guided to the air outlet end of the wind hood through an air guide plate, which helps to blow the hot air evenly onto the surface of the printed matter, so that the printed matter is evenly air-dried.

[0004] Although the above patent can utilize the negative pressure environment formed in the exhaust hood to make the paper and the conveyor belt fit more closely, when the size of the paper is smaller than the size of the exhaust hood, the paper cannot cover the exhaust hood. At this time, air will enter the exhaust hood from the unshielded part of the paper, so it is impossible to form a negative pressure area to adsorb the paper, which will lead to the problem of paper deviation during the operation. At the same time, it directly introduces the outside air and heats it through the electric heating wire. The dust contained in the air will also be blown onto the paper colloid, affecting the quality of the melamine impregnated paper. Utility Model Content

[0005] The utility model provides a melamine impregnated paper impregnation air-drying device to solve the problem that when air-drying papers of different sizes in the prior art, the papers are easily displaced under the action of flowing air, and the influence of dust on the quality of the melamine impregnated paper during the air-drying process is reduced.

[0006] The utility model is realized through the following technical scheme: a melamine impregnated paper glue air-drying device, comprising an air-drying chamber for air-drying operation, the air-drying chamber comprising an outer shell, the upper surface of the outer shell is provided with a heating chamber for heating air, an inner top wall of the outer shell is installed with an air pump, the input end of the air pump is connected with the heating chamber through a pipeline, the upper surface of the outer shell is slidably connected with a paper body to be processed, and the paper body to be processed is connected with an external winding device.

[0007] The air drying chamber also includes a plurality of sleeves, each of which is sleeved with an inner tube, and the outer surface of the inner tube is provided with a plurality of groups of circumferentially opened exhaust ports, and the output end of the air pump is connected with the sleeve through a hose, and the air pump can pump the hot air heated in the heating chamber into the interior of the sleeve, and discharge it through the exhaust port of the inner tube to air dry the paper body to be processed.

[0008] The heating chamber includes an insulation shell, and a plurality of connecting rods are installed on the inner wall of the insulation shell. An electric heating wire is installed between every two connecting rods. The electric heating wire is electrically connected to an external power supply. The electric heating wire is energized by the external power supply, thereby heating the electric heating wire to form hot air.

[0009] Two track plates are fixed to the inner wall of the insulation shell, and a first filter plate is slidably connected between the two track plates. The first filter plate passes through the insulation shell, and a handle is installed on the side of the first filter plate. The first filter plate can be pulled out by the handle and then replaced and cleaned to maintain the filtering capacity of the first filter plate.

[0010] A second filter plate is installed on the upper surface of the insulation shell. The filter port size of the second filter plate is larger than the filter port size of the first filter plate. The size of the second filter plate is larger than the size of the first filter plate. The air is filtered once through the second filter plate and then filtered twice by the first filter plate to reduce the influence of dust on the air-drying quality.

[0011] A connecting plate is arranged inside the shell, and the connecting plate is connected to the sleeve. An auxiliary spring and an auxiliary telescopic rod are installed on the upper surface of the connecting plate. The other ends of the auxiliary spring and the auxiliary telescopic rod are connected to the shell. The elastic force of the auxiliary spring can push the connecting plate to rise and fall, thereby achieving close contact with the paper body to be processed of different thicknesses.

[0012] The size of the sleeve is smaller than that of the outer shell, and the size of the paper body to be processed is smaller than that of the sleeve, which is beneficial to the stability of the sleeve and thus maintains the overall stability.

[0013] The utility model provides a melamine impregnated paper impregnation air-drying device, which has the following beneficial effects:

[0014] 1. The melamine impregnated paper glue air-drying device heats the air by setting a heating chamber, and the heated air is discharged through the exhaust port of the inner tube to air-dry the paper body to be processed. At the same time, the inner tube contacts and squeezes the paper body to be processed under the elastic force of the auxiliary spring. Through the squeezing and diversion of the inner tube, the problem that the paper is easily displaced under the action of flowing air is solved.

[0015] 2. The melamine impregnated paper glue air-drying device is provided with a first filter plate and a second filter plate, so that the outside air is first filtered through the second filter plate and then filtered through the first filter plate for a second time. At the same time, the first filter plate can be pulled out by a handle for replacement and cleaning, and the second filter plate can be disassembled, replaced and cleaned, so as to maintain the filtering capacity of the first filter plate and the second filter plate and reduce the influence of dust on the air-drying quality.

[0028] Please refer to Figure 1 , Figure 4 and Figure 5 The heating chamber 2 includes an insulation shell 201, and a plurality of connecting rods 202 are installed on the inner wall of the insulation shell 201. An electric heating wire 203 is installed between every two connecting rods 202. The electric heating wire 203 is electrically connected to an external power supply. The electric heating wire 203 is energized by the external power supply, so that the electric heating wire 203 is heated to form hot air.

[0029] Please refer to Figure 3 , Figure 4 and Figure 5 Two track plates 204 are fixed to the inner wall of the insulation shell 201, and a first filter plate 205 is slidably connected between the two track plates 204.
