Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

The temperature controller 3 and the heating wire 4 are electrically connected. The bracket 5 is fixedly installed at the bottom of the dryer 1.

[0022] By adopting the above technical scheme, it is possible to utilize the asynchronous motor 68 as the driving source and control the active stirring rod 63 and the driven stirring rod 64 to rotate in opposite directions through mechanical transmission, thereby achieving efficient turning of the polyurethane material in the material cage 61, and utilize the heating wire 4 to heat the wind blown by the fan 2, thereby achieving efficient and uniform drying of the polyurethane material in the material cage 61, and the temperature of the heating wire 4 can be adjusted according to the different high temperature resistance of the polyurethane material to avoid the polyurethane material being damaged by excessive drying temperature.

[0023] Example 2: Please refer to Figure 1-3On the basis of the first embodiment, a material cage 61 is fixedly installed inside the dryer 1, and the material cage 61 includes a drying cage and two support blocks, and the two support blocks are fixedly installed at the bottom of the drying cage. A discharge port is opened on one side of the drying cage, and a mesh door is hinged on the discharge port to facilitate the removal of the dried polyurethane material. A feed hopper 62 with one end penetrating and extending into the material cage 61 is fixedly installed on the top of the dryer 1, and an active stirring rod 63 with one end penetrating and extending to the outside of the material cage 61 is rotatably installed on the top wall of the material cage 61, and a pulley 63 with one end penetrating and extending to the outside of the material cage 61 is rotatably installed on the top wall of the material cage 61. The active stirring rod 64 is used to facilitate the uniform turning of the polyurethane material. The outer surfaces of the active stirring rod 63 and the driven stirring rod 64 are provided with a support assembly 65. The support assembly 65 includes two mounting grooves and two bearings. The two bearings are respectively fixedly installed on the inner circumferential walls of the two mounting grooves. The two bearings are both opened on the material cage 61. The outer surfaces of the active stirring rod 63 and the driven stirring rod 64 are respectively fixedly connected to the inner circumferential walls of the two bearings to facilitate the support of the rotation of the active stirring rod 63 and the driven stirring rod 64. The outer surfaces of the active stirring rod 63 and the driven stirring rod 64 are both fixedly connected with a worm gear 66.

[0024] By adopting the above technical solution, it is possible to control the two worm gears 66 to rotate in opposite directions, thereby controlling the active stirring rod 63 and the driven stirring rod 64 to rotate in opposite directions, thereby utilizing the rotating active stirring rod 63 and the driven stirring rod 64 to evenly stir the polyurethane material inside the material cage 61, and utilizing the heating wire 4 to heat the wind blown by the fan 2, thereby achieving even drying of the polyurethane material.

[0025] In the implementation of this example, a transmission rod 67 for driving the two worm gears 66 to rotate is rotatably installed at the bottom of the material cage 61. The transmission rod 67 includes two worms, the opposite ends of the two worms are welded, and the opposite ends of the two worms are rotatably installed at the bottom of the material cage 61. The outer surfaces of the two worms are respectively meshed with the outer surfaces of the two worm gears 66, so that the rotating transmission rod 67 drives the two worm gears 66 to rotate.

[0027] By adopting the above technical solution, it is possible to add the polyurethane material into the interior of the material cage 61 through the feed hopper 62, start the asynchronous motor 68 on the bracket 5, so that the asynchronous motor 68 drives the rotating shaft in the linkage assembly 69 to rotate, so that the rotating shaft drives the transmission rod 67 to rotate by means of a belt, and then the outer surfaces of the worm and the worm wheel 66 are engaged to drive the two worm wheels 66 to rotate in opposite directions.

[0028] The working principle of the above embodiment is:

[0029] When the dryer for processing hydrolysis-resistant polyurethane elastomer is in use, the polyurethane material is added into the interior of the material cage 61 through the feed hopper 62, and the asynchronous motor 68 on the bracket 5 is started, so that the asynchronous motor 68 drives the rotating shaft in the linkage assembly 69 to rotate, so that the rotating shaft drives the transmission rod 67 to rotate by means of a belt, and then the two worm wheels 66 are driven to rotate in opposite directions by means of the meshing of the outer surfaces of the worm and the worm wheel 66, thereby controlling the active stirring rod 63 and the driven stirring rod 64 to rotate in opposite directions, thereby achieving the goal of evenly turning the polyurethane material inside the material cage 61 by means of the rotating active stirring rod 63 and the driven stirring rod 64, and evenly drying the polyurethane material by means of the heating wire 4 to heat the wind blown by the fan 2.
