Description

Technical Field

[0001] The utility model relates to the technical field of drying systems, in particular to a drying system of a paper compound machine. Background Art

[0002] Mechanical paper laminating machine is a kind of equipment widely used in printing industry. Its function is to laminate paper with other materials to enhance the strength, water resistance and surface smoothness of paper.

[0003] Mechanical paper laminating machines combine paper with other materials through a series of process steps. The paper is first fed into the machine and then coated by a coater. The coater evenly coats the required composite material on the surface of the paper. After coating, the paper enters the drying room and is heated at high temperature to quickly dry the coated material. Next, the surface of the paper is embossed by an embossing machine to increase its surface smoothness and texture effect. Finally, after cutting and collection, the composite paper products are separated and can be further processed.

[0004] At present, hot air drying is mostly used in the drying stage. The hot air evaporates the moisture on the composite paper and dries the composite paper, and increases the temperature and humidity of the air in the dryer. Usually, an exhaust fan is used on the top of the dryer to discharge the high-temperature and high-humidity air inside. However, since the composite paper is transported inside the dryer, the air below it cannot be discharged. The moisture in the air will be absorbed by the composite paper again, affecting the drying effect of the composite paper. At the same time, after the temperature of the composite paper rises, it needs to be cooled for subsequent processing. The cooling effect of the existing cooling device is not uniform enough, which will affect the quality of the composite paper.

[0005] Therefore, the present application provides a drying system for a paper laminating machine to meet the demand. Utility Model Content

A pressure roller 33 is slidably connected to the top of the roller 32, and both ends of the rotating shaft of the pressure roller 33 slide in the vertical slide grooves 31 respectively, and the contact surface between the roller 32 and the pressure roller 33 corresponds to the position of the paper passing port 30.

[0043] Working principle of the utility model: the end plate 21, the partition plate 22 and the buckle cover 7 on the workbench 2 form a hot air chamber, a cooling chamber and a cooling chamber. When drying, the composite paper passes through the conveying box 3 from the paper passing port 30, and is supported by the roller 32 and pressed by the pressure roller 33. The pressure roller 33 slides in the vertical slide groove 31, which is convenient for the composite paper to be adjusted when passing through, so that the composite paper passes through the hot air chamber, the cooling chamber and the cooling chamber and can be stably transported. In this process, the hot air blower 11, the hair dryer 12 and the air conditioner 13 beside the frame 1 are all working, and the bracket 4 The air supply box 5 and the exhaust box 6 are supported and fixed on the upper and lower sides of the composite paper. The hot air blower 11 supplies hot air to the air supply box 5 in the hot air chamber through the air inlet pipe 50. The hot air is blown out from the air outlet 51 and blown to the upper and lower surfaces of the composite paper. The hot air evaporates the moisture on the composite paper and heat-dries the composite paper. At the same time, the exhaust fan 10 extracts the hot air in the hot air chamber through the exhaust pipe 62 and the exhaust box 6 to reduce the air humidity in the hot air chamber. At the same time, the hair dryer 12 blows the room temperature air into the cooling chamber to heat and dry the composite paper. The composite paper is initially cooled down, and the air conditioner 13 sends the low-temperature air into the cooling chamber to cool the composite paper again. In this process, the air sent into the hot air chamber, the cooling chamber, and the cooling chamber is blown out obliquely from the air outlet ducts 51 on the front and rear sides of the air supply box 5, so that the air is in uniform contact with the surface of the composite paper, which can make the temperature of the composite paper rise and fall evenly, reduce the influence of thermal expansion and contraction on the composite paper, and improve the processing quality of the composite paper. The upper and lower exhaust boxes 6 respectively extract the air on the upper and lower sides of the composite paper, which can ensure the ventilation efficiency. 61 can increase the air flow speed at the exhaust port 60 and reduce noise. The observation window 70 can be used to observe the composite paper conveying and drying process. The practical handle 71 can be used to lift and remove the buckle cover 7 for maintenance of internal components. The connecting frame 52 can be used to connect and fix the exhaust box 6. When installing the buckle cover 7, the bottom of the buckle cover 7 is placed in the support bar 20. After placement, the baffle 23 on the end plate 21 and the partition 22 contacts the edge of the inner wall of the buckle cover 7, thereby enhancing the airtightness between the buckle cover 7 and the end plate 21 and the partition 22.
