[0039] It should be noted that, as shown in the figure, a plurality of through holes are opened around the perforated inner frame 2 for hot air output to dry the diaphragm passing through the inner side of the perforated inner frame 2. First, the hollow mounting head 701 is used as the starting point, and the fan 712 is set to work. Through the connected pipes, one end of the hollow mounting head 701 generates negative pressure to suck the air inside the thermal insulation outer box 1. The temperature and humidity of the extracted air are detected in real time by the temperature and humidity sensor 702, and then the air is circulated to the dehumidification device 704 for dehumidification. After dehumidification, the air is heated by the electric heating wire 706 inside the heating box 705. After heating, the air passes through the second return air duct 707 and then circulated to the thermal insulation outer box 1 through the fan 712 for drying the diaphragm. During the drying process, when the humidity in the air is high, the air is continuously heated and dried. When the humidity is low, the first motor 709 opens the valve plate 710 to suck the cold air filtered by the drying filter 711 and circulates it to the inside of the thermal insulation outer box 1. The drying heat is inversely proportional to the humidity, which prevents the diaphragm from deforming due to excessive drying, and the drying process is more linear.

The mixing assembly is provided with a mixing pipe 801, and a rotating shaft 803 with a first stirring blade 804 is installed inside the mixing pipe 801. The rotating shaft 803 drives the first stirring blade 804 to rotate, so that the cold air and the hot air passing through can be quickly mixed, thereby improving the uniformity of the air temperature;

[0041] In some embodiments, see Figure 1 , Figure 7The mixing assembly includes a connecting pipe 802 and a second motor 805, one end of the connecting pipe 802 is fixedly installed at the bottom of one end of the mixing pipe 801, the other end of the connecting pipe 802 is fixedly installed at the output end of the fan 712, the second motor 805 is fixedly installed at one end of the mixing pipe 801, the output end of the suction pipe 708 is connected to the air inlet 5, the rotating shaft 803 is rotatably connected inside the mixing pipe 801, and one end of the rotating shaft 803 is fixedly installed at one end of the output shaft of the second motor 805, and the first stirring blade 804 is fixedly installed on the outer wall of the rotating shaft 803.

[0042] It should be noted that during the air circulation process, when the suction pipe 708 is used to draw cold air to lower the drying temperature, the hot air and cold air pass through the mixing pipe 801, and the second motor 805 drives the rotating shaft 803 to rotate, and the first stirring blade 804 is used to quickly stir and mix the hot air and the cold air to avoid uneven distribution of the hot and cold air when drying in the perforated inner frame 2, thereby further improving the drying quality.

[0043] The heat preservation component is arranged between the heat preservation outer box 1 and the dynamic adjustment drying component. The heat preservation component is provided with a liquid cavity 901 and a heat exchanger 902, the liquid cavity 901 is filled with liquid, and the liquid is circulated to the inside of the heat exchanger 902 for heating, so as to form a hot water protection layer around the heat preservation outer box 1, thereby reducing the influence of the outside on the temperature inside the heat preservation outer box 1;

[0044] In some embodiments, see Figure 1 , Figure 3 , Figure 5 The insulation component includes a liquid pump 903, a liquid supply pipe 904 and a return pipe 905.

[0046] The air stirring component is arranged between the heat-insulating outer box 1 and the perforated inner frame 2. The air stirring component is provided with two fixing rings 1001 and a plurality of connecting rods 1003. The connecting rods 1003 are also provided with second stirring blades 1004. The two fixing rings 1001 are used to rotate in the cavity between the heat-insulating outer box 1 and the perforated inner frame 2, driving the connecting rods 1003 and the second stirring blades 1004 to revolve, stirring the hot air transported to the cavity between the heat-insulating outer box 1 and the perforated inner frame 2, so that the hot air can surround the perforated inner frame 2 for a week and be discharged from the exhaust holes around the perforated inner frame 2, surrounding and drying the diaphragm;

[0047] In some embodiments, see Figure 4 The air stirring assembly includes a plurality of supporting rollers 1002, an inner tooth groove 1005, a third motor 1006 and a driving gear 1007.

[0048] It should be noted that, in the process of circulating drying, when the hot air passes through the cavity between the thermal insulation outer box 1 and the perforated inner frame 2, the third motor 1006 is used to drive the driving gear 1007, and the driving gear 1007 is engaged with the inner tooth groove 1005, so that the fixed ring 1001 rotates under the support of the support roller 1002, and the second stirring blade 1004 in the middle of the connecting rod 1003 is used to stir the hot air transported to the cavity between the thermal insulation outer box 1 and the perforated inner frame 2, so that the hot air can surround the perforated inner frame 2 and be discharged from the exhaust holes around the perforated inner frame 2, surrounding the diaphragm for drying, thereby improving the uniformity of hot air distribution during drying and improving the drying effect.

[0049] The working process and principle of the present invention are as follows: when in use, the diaphragm enters the perforated inner frame 2 through the feed port 3 for drying. First, starting from the hollow mounting head 701, the fan 712 is started, and the air inside the heat preservation outer box 1 is sucked by one end of the hollow mounting head 701 through each connected pipe. The temperature and humidity of the extracted air are detected in real time by the temperature and humidity sensor 702, and then the air is circulated to the dehumidification device 704 for dehumidification. After dehumidification, the air is heated by the electric heating wire 706 inside the heating box 705. The air is heated, and after heating, it passes through the second return air duct 707, and then circulates to the inside of the heat preservation outer box 1 through the fan 712 to dry the diaphragm. During the drying process, when the humidity in the air is high, it continues to heat and dry. When the humidity is low, the first motor 709 opens the valve plate 710 to suck the cold air filtered by the drying filter 711, and when the suction pipe 708 is used to suck the cold air to lower the drying temperature, the hot air and the cold air pass through the mixing pipe 801, and the second motor 805 drives the rotating shaft 803 to rotate, and the first stirring blade 804 is used to quickly stir the hot air. The hot air and the cold air are stirred and mixed to avoid uneven distribution of the hot and cold air when they are dried in the perforated inner frame 2. Then the air is circulated into the cavity between the perforated inner frame 2 in the thermal insulation outer box 1. The driving gear 1007 is driven by the third motor 1006. The driving gear 1007 is meshed with the inner tooth groove 1005, so that the fixed ring 1001 rotates under the support of the supporting roller 1002. The hot air transported to the cavity between the thermal insulation outer box 1 and the perforated inner frame 2 is stirred by the second stirring blade 1004 in the middle of the connecting rod 1003. The hot air moves so that it can surround the perforated inner frame 2 for a week and be discharged from the exhaust holes around the perforated inner frame 2, surrounding and drying the diaphragm, and then circulate again. At the same time, during the drying process, the water in the liquid cavity 901 is continuously circulated to the heat exchanger 902 by utilizing the cooperation of the liquid pump 903, the liquid supply pipe 904 and the return pipe 905. During the drying process, the water circulated to the heat exchanger 902 is continuously heated, forming a heat-insulating layer composed of water for the heat-insulating outer box 1, thereby reducing the influence of the outside world on the internal temperature of the heat-insulating outer box 1.
