Description

Technical Field

[0001] The invention relates to the technical field of impregnated paper production, in particular to a drying device for impregnated paper production capable of recovering preheating. Background Art

[0002] Impregnated paper, full name melamine impregnated paper, also known as "melamine" paper. It is a kind of plain base paper or printed decorative paper, which is impregnated with amino resin and dried to a certain degree to form a glued paper with a certain resin content and volatile content.

[0003] During the production process of impregnated paper, after hot pressing, the impregnated paper may contain a certain amount of moisture inside. The inside of the impregnated paper can be dried with the help of drying equipment. During the drying process, sometimes in order to maintain production efficiency, the temperature inside the drying chamber is adjusted to a higher level, resulting in the moisture in the substrate evaporating too quickly during the drying process, generating stress, and then causing warping.

[0035] A guide tube 24 is installed inside the drying box 11, one end of which is connected to the input port of the air compressor 21, a rectangular groove is provided on one side of the guide tube 24, and a sealing slide 23 is movably provided inside the rectangular groove, an exhaust plate 25 is installed at one end of the sealing slide 23, and a plurality of separation grooves are provided on the exhaust plate 25. The exhaust plate 25 can move with the sealing slide 23, and the position of the exhaust plate 25 can be adjusted according to different temperatures, so that the internal water flow can be quickly extracted to reduce the residual water vapor inside, so that the inside of the drying box 11 remains dry, and the drying efficiency of the equipment is ensured.

[0036] like Figure 8 As shown, a fixing frame 32 is installed on the inner wall of the winding bracket 3, and a winding shaft 33 is rotatably arranged inside the fixing frame 32. The winding shaft 33 is used to limit the recovery of the impregnated paper. The winding bracket 3 can be directly turned over to disassemble and assemble the winding shaft 33, and can be quickly replaced.

[0037] like Figure 8 As shown, in order to reduce the occurrence of wrinkles during the winding process of the equipment, a plurality of buffer pads 34 are installed on the fixed frame 32. The buffer pads 34 are triangular in shape. A rubber gasket is installed on the side of the buffer pad 34 close to the winding shaft 33 for auxiliary limiting the impregnated paper. A reset pressure plate 35 is inserted on the buffer pad 34. One end of the reset pressure plate 35 is arc-shaped and rests on the impregnated paper during transmission. A plurality of spring shafts are installed at one end of the reset pressure plate 35, and one end of the spring shaft rests on the inner wall of the buffer pad 34. The impregnated paper can be wound on the winding shaft 33, and under the action of the rubber gasket at one end of the reset pressure plate 35, it plays a limiting role to reduce the looseness during the winding process. The reset pressure plate 35 can rest on the top of the impregnated paper, and can stretch the impregnated paper during transmission so that it can be laid flat on the winding shaft 33.

[0038] like Figure 8 As shown, due to the high temperature inside the drying box 11, the winding shaft 33 needs to be cooled down for a certain period of time before being disassembled and assembled, so as to reduce the safety hazards of the operators during the operation. A plurality of heat dissipation grooves 31 are provided on the winding bracket 3, and the positions of the heat dissipation grooves 31 correspond to the positions of the buffer pads 34. The heat dissipation grooves 31 are used to assist in cooling. The external airflow can enter through the heat dissipation grooves 31, and the impregnated paper of the winding hand can be cooled, so that the subsequent disassembly and replacement of the winding shaft 33 is convenient, the burn situation of the operators is reduced, and the intermediate cooling time can be saved.

[0039] like Figure 5 and Figure 6 As shown, the impregnated paper may be wrinkled or compressed during the transmission process, and a plurality of docking plates 45 are installed on the surface of the transmission shaft 4. The docking plates 45 are symmetrically arranged on the transmission shaft 4 in pairs, and a movable plug rod 41 is installed and inserted between the docking plates 45. A plurality of reset plug rods 43 are installed at the bottom of the movable plug rod 41, and the reset plug rod 43 is against the surface of the transmission shaft 4. A plurality of support rings 42 are installed on the top of the movable plug rod 41, and the support ring 42 is used to be against one side of the impregnated paper. During the transmission process, the impregnated paper can be squeezed between the support ring 42 at the top of the movable plug rod 41, and the impregnated paper can be stretched during the transmission process to reduce the occurrence of wrinkles. The support ring 42 plays a supporting role, which can enable air flow to flow at the bottom of the impregnated paper, thereby improving the overall drying efficiency and reducing the situation where the water content inside the impregnated paper is high and causes incomplete drying.

[0040] like Figure 7 As shown, in order to ensure uniform drying and reduce the warping of the impregnated paper due to uneven temperature at both ends under stress, a plurality of air inlet grooves 411 are provided on the side wall of the movable plug rod 41. The air inlet grooves 411 are arranged in a uniform array at both ends of the movable plug rod 41. An exhaust plate 44 is installed on the top of the movable plug rod 41. The exhaust plate 44 is arc-shaped and made of nylon mesh.

[0041] A plurality of limiting tubes 46 are installed between the docking plates 45. The limiting tubes 46 are arc-shaped. The airflow inside the transmission shaft 4 can be transported to the inside of the air inlet groove 411 along the limiting tubes 46, and can blow air to dry both sides of the impregnated paper. Under the action of squeezing the top of the movable plug rod 41, the positions of the air inlet groove 411 and the air delivery holes of the limiting tubes 46 correspond to each other, and the external device can also transmit heat flow to the inside of the transmission shaft 4. Under the action of the limiting tubes 46, the airflow can enter the air inlet groove 411 and be discharged along the exhaust plate 44, so that the impregnated paper and one side of the cross section of the transmission shaft 4 can be blown dry, and both sides of the impregnated paper can be dried, thereby reducing the warping caused by uneven drying and ensuring the processing quality of the equipment.

[0042] Working principle: First, when the impregnated paper needs to be dried, the air compressor 21 can be operated to quickly extract the water vapor inside the drying box 11 and transport it to the inside of the hollow tube 22. The impregnated paper can be heated during the transmission process to ensure that it has a certain temperature before the drying process to prevent the temperature inside the drying box 11 from being too high, which may cause the water to evaporate quickly and cause the edge to warp and twist. In addition, during the transmission process, the impregnated paper can be stretched by the transmission shaft 4 to reduce the folding and twisting, so that it can be transmitted to the winding shaft 33, and during the transmission process, the impregnated paper can be stretched by the transmission shaft 4 to reduce the folding and twisting. During the process, under the action of the air compressor 21, the part with water vapor inside the drying box 11 can be transferred to the inside of the hollow tube 22 along the air extraction plate 25, and the position of the air extraction plate 25 can be adjusted, so as to reduce the situation that the inside of the drying box 11 is filled with water mist after a long period of processing, and the overall drying efficiency can be effectively improved. After the airflow with water is transferred to the inside of the hollow tube 22, the dust in the air hole can be separated under the cooperation of the adsorption shaft and the water absorption plate 27, and the water vapor is gathered inside the water absorption plate 27, which is convenient for subsequent unified treatment and plays a role in purifying the processing environment.

[0043] Then, during the transmission process, the impregnated paper can be squeezed between the support ring 42 at the top of the movable plug rod 41, and the impregnated paper can be stretched during the transmission process to reduce the occurrence of wrinkles. Under the action of squeezing the top of the movable plug rod 41, the positions of the air inlet groove 411 and the air delivery hole of the limiting tube 46 correspond to each other, and the external device can also transmit the heat flow to the inside of the transmission shaft 4. Under the action of the limiting tube 46, the air flow can enter the air inlet groove 411 and be discharged along the exhaust plate 44, so that one side of the cross section of the impregnated paper and the transmission shaft 4 can be blown and dried to reduce the warping caused by uneven drying on both sides.

[0044] Finally, during the transmission process, the impregnated paper can be wound on the winding shaft 33, and under the action of the rubber gasket at one end of the reset pressure plate 35, it plays a limiting role to reduce the looseness during the winding process, and the reset pressure plate 35 can be against the top of the impregnated paper, and the impregnated paper during the transmission process can be stretched to make it lay flat on the winding shaft 33. At the same time, the external airflow can enter through the heat dissipation groove 31 to dissipate the heat of the impregnated paper on the winding hand, which is convenient for the subsequent disassembly and replacement of the winding shaft 33, reducing the risk of burns to the operator.

[0045] 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.
