A suction hood 4 is fixedly connected to the upper part of the drying chamber 1. A collection box 5 is fixedly connected to the top right side of the drying chamber 1, and a sealing sleeve (not shown in the figure) is provided on the outside of the collection box 5 to facilitate opening and cleaning of impurities inside. An exhaust fan 7 is located on the left side of the collection box 5, and air supply pipes 8 are fixedly connected to both sides of the exhaust fan 7 to deliver hot air. A drying chamber 9 is fixedly connected to the bottom of the drying chamber 1, containing a solid desiccant. A sealing cover 10 is provided on the front side of the drying chamber 9 for easy replacement of the desiccant. Connecting parts 11 are fixedly connected to both sides of the sealing cover 10 for connection. Both connectors 11 have flexible spring sheets 12 fixedly connected to their inner sides, with the ends of the flexible spring sheets 12 being U-shaped. A pressing block 13 is fixedly connected to the outer end of the flexible spring sheet 12; pressing the pressing block 13 causes the flexible spring sheet 12 to contract and deform, thus facilitating the release of the limiting position on the flexible spring sheet 12 and allowing the sealing cover 10 to be opened. A sealing groove 15 is provided on the front side of the drying chamber 9. Installation components are connected to both sides of the drying chamber 9. Cylinders 20 are fixedly connected to both sides of the top of the drying chamber 1. A lifting frame 21 is fixedly connected to the output end of the cylinder 20, enabling the lifting frame 21 to move up and down. The lifting frame 21 passes through and is slidably connected to the top of the drying chamber 1. Conveyor rods 22 are fixedly connected to the inner bottom of both lifting frames 21. The outer surface of the conveyor rods 22 is smooth, facilitating the heating and conveying of the plush fabric. An electric heating rod 23 is fixedly connected inside the conveyor rod 22, enabling it to be heated.

[0033] Reference Figure 3 The installation assembly includes a mounting base 16, the inner side of which is fixedly connected to the outer wall of the drying chamber 9. A slot 25 is provided at the front end of the mounting base 16, and a groove 17 is provided on the outer side of the mounting base 16, which communicates with the slot 25. Two limiting blocks 18 are fixedly connected in the slot 25, and the limiting blocks 18 are located on both sides of the groove 17. The installation assembly can limit the flexible spring pieces 12 on both sides of the sealing cover 10, which facilitates the installation and removal of the sealing cover 10, thereby facilitating the replacement of the desiccant in the drying chamber 9.

[0034] Reference Figure 1-4The bottom of the collection box 5 is fixedly connected to the suction hood 4 via a pipe. A filter screen 6 is fixedly connected inside the collection box 5, which can filter and collect lint. The end of the left air supply pipe 8 passes through and is fixedly connected to the drying box 9, and the end of the right air supply pipe 8 passes through and is fixedly connected to the collection box 5. A sealing strip 14 is fixedly connected to the inside of the sealing cover 10. The sealing strip 14 is set in the sealing groove 15. The sealing effect of the sealing cover 10 on the drying box 9 is improved by inserting the sealing strip 14 into the sealing groove 15. A connecting pipe 19 passes through and is fixedly connected to the right side of the drying box 9, and the end of the connecting pipe 19 passes through and is fixedly connected to the bottom of the drying box 1. The dried hot air can be sent back into the drying box 1 through the connecting pipe 19. Support legs 24 are fixedly connected to the four corners of the bottom of the drying box 1.

[0035] Working principle: The free end of the nonwoven fabric to be dried is fixed with external auxiliary tools such as support rods, and then horizontally passed through the inlet / outlet 2 and the two conveyor rods 22 in sequence. After the fabric passes through, it is fixed to the winding mechanism. The auxiliary tools are removed, and then the cylinder 20 is activated to drive the lifting frame 21 to rise and fall, which in turn drives the conveyor rods 22 to rise and fall. By staggering the two conveyor rods 22 vertically, the nonwoven fabric in the drying chamber 1 is stretched and tightened into an "S" shape, extending the time it stays in the drying chamber 1. After the nonwoven fabric is fixed, the electric heating plate 3 and the exhaust fan 7 can be turned on. The power of the electric heating plate 3 can be determined according to the specific volume of the drying chamber 1 and the humidity of the fabric, etc. Alternatively, an existing adjustable temperature heating plate can be used for real-time temperature adjustment. An appropriate amount of desiccant is placed into the drying chamber 9. Then, the sealing strip 14 of the sealing cover 10 is inserted into the sealing groove 15 on the outside of the drying chamber 9. Simultaneously, the flexible spring pieces 12 on both sides of the sealing cover 10 are inserted into the slots 25 on both sides of the drying chamber 9 for mounting components. At this time, the U-shaped flexible spring pieces 12 are compressed by the limiting block 18, causing them to contract. The pressing block 13 enters the slot 17. When the flexible spring pieces 12 are fully inserted into the slot 25, the outer end of the flexible spring pieces 12 is released from the compression of the limiting block 18, thus resetting them and opening them within the slot 25. The limiting block 18 then limits the flexible spring pieces 12, completing the fixed installation of the sealing cover 10. The plush cloth, heated by the electric heating plate 3, generates hot air, which is collected by the suction hood 4 above. The suction hood 4 delivers the hot and humid air to the collection box 5 through a pipe. The filter 6 inside the collection box 5 filters out impurities such as lint carried in the hot and humid air, preventing impurities from entering subsequent equipment. The filtered hot and humid air, driven by the exhaust fan 7, enters the drying chamber 9 through the air supply duct 8 on the right. The drying chamber 9 uses an internal desiccant (not shown in the diagram) to dry the hot and humid air, removing moisture and turning it back into dry hot air. The dried hot air then returns to the drying chamber 1 through the connecting pipe 19 on the right side of the drying chamber 9, achieving hot air recycling, improving energy efficiency, and reducing drying energy consumption.
