[0002] In the process of producing base paper for paper cups, the drying link has an important impact on product quality and production efficiency. Traditional drying devices usually adopt electric heating wires or gas heating methods. Although the drying effect can be achieved, the energy consumption is high and the drying uniformity needs to be improved. In the prior art, continuous dryers are mostly used for drying base paper for paper cups. The wet base paper for paper cups is sent into the drying chamber through a conveyor belt, and a heating element is used for drying. Problems such as high energy consumption, low thermal efficiency, and uneven drying of traditional drying methods affect the quality and production cost of base paper for paper cups.

[0003] Publication No. CN111809445A discloses a drying device for paper production, including a box body. One side of the inner wall of the box body is fixedly connected with a motor through a connecting plate, and the output shaft of the motor is fixedly connected with a first lead screw. One end of the first lead screw away from the motor is fixedly connected with a connecting block, and one end of the connecting block away from the first lead screw is fixedly connected with a second lead screw. One end of the second lead screw is rotationally connected with the inner wall of the box body through a connecting plate. Sliders are sleeved on the surfaces of the first lead screw and the second lead screw, and the top of the slider is slidably connected with the top of the inner wall of the box body. The bottom of the slider is fixedly connected with a mounting seat, and a blower is arranged inside the mounting seat. When the first lead screw and the second lead screw start to rotate, the slider starts to slide, thereby driving the blower to start moving. Then, the blower and the heating cylinder are started to dry the paper, improving the quality of the product. However, during the drying process of the paper by this device, the tensioning efficiency of the paper surface is too low, and wrinkles may occur. Summary of the Utility Model
