[0020] Combined with the drawings, the utility model includes an outer shell 1. An inlet for the cloth 2 is provided at the left end of the outer shell 1, and an outlet for the cloth 3 is provided at the right end. A plurality of cloth supporting devices are arranged in the outer shell 1. The plurality of cloth supporting devices are evenly distributed in the left-right direction. Each cloth supporting device includes a connecting arm 4. A rotating shaft 5 in the front-rear direction is installed at the midpoint of the connecting arm 4. The rear end of the rotating shaft 5 is installed on the rear wall of the outer shell 1 through a bearing. A cloth roller 6 in the front-rear direction is installed at each end of the connecting arm 4. The connecting arm 4 can drive the two cloth rollers 6 to revolve around the rotating shaft 5, and the cloth roller 6 can also rotate by itself. The cloth enters the outer shell 1 from the inlet for the cloth 2 at the left end, passes through the two cloth rollers 6 of a plurality of cloth supporting units in sequence to the right, and then passes out from the outlet for the cloth 3. A plurality of heating tubes 7 are provided at the inner top and inner bottom of the outer shell 1. Air blowers 8 are installed on the upper and lower walls of the outer shell 1. The air blowers 8 blow air into the outer shell 1 and the air is heated by the heating tubes 7. An air outlet pipe 9 is provided on the outer shell 1, and the hot air dries the cloth.

[0021] Inside the described outer casing 1, there are two horizontal partitions 10, upper and lower. The partitions 10 are provided with air holes 11. A sandwich layer is formed between the upper partition 10 and the upper wall of the outer casing 1, and a sandwich layer is formed between the lower partition 10 and the lower wall of the outer casing 1. The heating tubes 7 are located in the sandwich layers. The partitions 10 can prevent the cloth from directly contacting the heating tubes 7 and can also make the hot air blow into the outer casing 1 more evenly.

[0022] A pressure valve 12 is installed on the described air outlet pipe 9. When the pressure inside the outer casing 1 reaches the opening value of the pressure valve 12, the pressure valve 12 opens, and the air outlet pipe 9 starts to exhaust. The pressure valve 12 can keep the pressure inside the outer casing 1 slightly higher than the atmospheric pressure, which can make the hot air distribute more evenly inside the outer casing 1 and avoid dead corners.

[0023] A set of cloth feeding counter-rollers 13 are installed at both the cloth inlet 2 and the cloth outlet 3 for feeding the cloth. The cloth feeding counter-rollers 13 at the cloth inlet 2 can also squeeze the cloth to squeeze out excessive moisture in the cloth for preliminary dehydration.

[0024] A belt pulley 14 is installed at the rear end of the rotating shaft 5 of each of the described cloth supporting units. The rotating shafts 5 of the cloth supporting units are all driven by a driving motor via a belt 15.

[0025] A cloth guiding groove 16 in the left-right direction is opened on the front wall of the described outer casing 1 for guiding the cloth to pass through the outer casing 1 initially.

[0026] A door panel 17 is hinged on the front wall of the described outer casing 1 above the cloth guiding groove 16. The door panel 17 can be lowered to close the cloth guiding groove 16.

[0027] A magnetic strip 18 is provided below the cloth guiding groove 16. After the door panel 17 is lowered, the magnetic strip 18 adsorbs the door panel 17 to make the door panel 17 close tightly.

[0028] A sealing strip 19 is provided on the door panel 17. After the door panel 17 is closed, a seal is formed between the door panel 17 and the outer wall of the outer casing 1 to prevent air leakage through the cloth guiding groove 16.

[0029] In the initial state before the start of the present utility model, the two cloth rollers 6 of each group of cloth supporting units are in a state where the left cloth roller 6 is higher and the right cloth roller 6 is lower. Open the door panel 17, pass the end of the cloth through the cloth feeding counter-rollers 13 at the cloth inlet 2 into the outer casing 1, then guide the cloth to pass through between the two cloth rollers 6 of multiple groups of cloth supporting units in sequence through the cloth guiding groove 16, and finally pass through the cloth feeding counter-rollers 13 at the cloth outlet 3, and then close the door panel 17; at this time, the left cloth roller 6 of each group of cloth supporting units is located above the cloth, and the right cloth roller 6 is located below the cloth.

[0030] Fix the right end of the cloth in place, start the drive motor, and drive the rotating shafts 5 of all cloth supporting units to rotate counterclockwise through the belt 15, so that each group of cloth supporting units rotates to the state where the cloth roller 6 on the left is low and the cloth roller 6 on the right is high. During this process, the cloth is stretched into a wavy shape by the cloth roller 6, and then start the feeding pair rollers 13 at the cloth inlet 2 and the cloth outlet 3 to feed the cloth, and at the same time start the fan 8 and the heating tube 7 to send hot air into the outer shell 1 to dry the cloth.

[0031] When initially threading the cloth through the outer shell 1 of the present utility model, the cloth only needs to be linearly threaded through the outer shell 1, without threading the cloth up and down between the cloth rollers 6. The rotation of the cloth supporting unit can automatically stretch the cloth into a wavy shape, greatly reducing the difficulty of initially pulling the cloth and improving the work efficiency.

[0032] The present utility model makes the hot air blow into the outer shell 1 more evenly through the air distribution of the partition plate 10, and forms a pressure slightly higher than the atmospheric pressure in the outer shell 1 through the pressure valve 12, so that the hot air fills the outer shell 1 and avoids dead corners, thereby enabling the cloth to be dried more evenly and fully.
