[0021] As shown in the figure, a wind cooling device applied to an extrusion device is provided, comprising: a discharge pipe 1, the discharge pipe 1 is connected to the molding discharge port of the extrusion device, and the side wall of the discharge port of the discharge pipe 1 is provided with one or more air inlets 2 and one or more first air outlets 3; a ring body 4, the ring body 4 is a hollow structure, the ring body 4 is sleeved at the position of the air inlet 2 of the discharge port, and the inner wall of the ring body 4 is provided with one or more second air outlets 5, and the second air outlets 5 are communicated with the air inlet 2; a pipe fitting interface 6, the pipe fitting interface 6 is arranged on the ring body 4, and the pipe fitting interface 6 is connected to an external air source through a pipeline; when working, the external air source inputs compressed gas into the ring body 4 through the pipe fitting interface 6, and the compressed gas enters the air inlet 2 of the discharge pipe 1 from the second air outlet 5 of the ring body 4, and the compressed gas air-cools the molded product of the discharge pipe 1, and the compressed gas is discharged from the first air outlet 3 of the discharge pipe 1.

[0022] In the production process of the fiber rod, the molding temperature is 200°C. After the fiber rod is molded, it is cooled naturally, which leads to slow cooling speed, low production efficiency and unstable molding quality.

[0023] The following describes the use of the air cooling device in a fiber rod production equipment. When in use, the discharge pipe 1 is connected to the molding discharge port of the fiber rod, the ring body 4 is sleeved on the air inlet 2 of the discharge pipe 1, and a first air outlet 3 of the discharge pipe 1 is reserved. The external air source and the pipe interface 6 are connected through a pipeline. When in use, the fiber rod is squeezed out of the discharge pipe 1. At the same time, the compressed gas reaches the pipe interface 6 through the pipeline, and the compressed gas enters the ring body 4. The compressed gas is discharged from the second air outlet 5 of the ring body 4 and enters the air inlet 2 of the discharge pipe 1, so that the fiber rod in the discharge pipe 1 is air-cooled to achieve rapid cooling and improve the molding quality of the fiber rod. Then, the compressed gas is blown out from the reserved first air outlet 3.

[0024] In implementation, a suitable number of air inlets 2, first air outlets 3 and second air outlets 5 may be selected according to implementation conditions, so as to achieve faster air cooling.

[0025] As shown in the reference figure, a first flange 7 is provided at the front end position of the inner wall of the ring body 4, and the first flange 7 protrudes radially. A second flange 8 is provided at the rear end position of the inner wall of the ring body 4, and the second flange 8 protrudes radially. When the ring body 4 is sleeved on the discharge pipe 1, the first flange 7 and the second flange 8 are in contact with the outer wall of the discharge pipe 1, and the first flange 7, the second flange 8 and the outer wall of the discharge pipe 1 form a passage for compressed gas to flow.

[0026] In order to facilitate the compressed gas to enter the air inlet 2 of the discharge pipe 1, a protruding first flange 7 and a second flange 8 structure are provided at the front and rear end positions on the ring body 4. Therefore, when the ring body 4 is sleeved on the discharge pipe 1, due to the raised first flange 7 and second flange 8, the inner wall of the ring body 4 and the outer wall of the discharge pipe 1 are not tightly attached, and there is a certain space between the two. Therefore, when the compressed gas enters the ring body 4, the compressed gas is discharged from the second air outlet 5, and the compressed air is filled in the space formed by the first flange 7, the second flange 8, the inner wall of the ring body 4 and the outer wall of the discharge pipe 1. The compressed air can enter the discharge pipe 1 from the air inlet 2 at other positions of the outer wall of the discharge pipe 1 for air cooling.

[0027] As shown in the drawings, the utility model includes a screw 9 , which is arranged on the ring body 4 , and the screw 9 is fixed to the discharge pipe 1 through the ring body 4 .

[0028] The ring body 4 is locked on the discharge pipe 1 by fixing with screws 9 .

[0029] A detachable forming die is installed in the discharge pipe 1, and the forming die is used to form the shape of the extruded product. The provided forming die is used to limit the shape of the product, such as a round fiber rod or a flat fiber rod.

[0030] The above does not limit the technical scope of the present invention. Any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
