[0032] Example: Figure 1-4 As shown, this utility model provides a technical solution: a polyester staple fiber screw extrusion device, including a screw extruder 1, and a cooling assembly 2 installed on one end face of the screw extruder 1;

[0033] The cooling assembly 2 includes an extruder head 201, a bracket 202, a base 203, an air pump mounting bracket 204, a connecting air pump 205, an air inlet pipe 206, an air collection hood 207, an air outlet pipe 208, an outer annular pipe 209, a connecting air pipe 210, an inner annular pipe 211, an inner air outlet 212, an outer air outlet 213, a water tank 214, and an inclined air inlet pipe 215.

[0034] The screw extruder 1 has an extrusion head 201 installed at its extrusion end. A bracket 202 is provided at one end of the screw extruder 1, and a base 203 is welded to the bottom of the bracket 202. An air pump mounting bracket 204 is welded to one end of the screw extruder 1. A connecting air pump 205 is installed inside the air pump mounting bracket 204. An air inlet pipe 206 is connected to the air inlet end of the connecting air pump 205, and a gas collection hood 207 is welded to the air inlet end of the air inlet pipe 206. An air outlet pipe 208 is connected to the air outlet end of the connecting air pump 205. An outer annular pipe 209 is welded to one end face of the bracket 202. The air outlet end of the air outlet pipe 208 is connected to the outer annular pipe 209 for convenient rapid air delivery. Two connecting air pipes 210 are welded to the inner annular pipe 211, symmetrically welded to each other. On the outside, the internal chambers of the outer annular tube 209 and the inner annular tube 211 are connected by a connecting air pipe 210 to facilitate the delivery of cooling gas. One end of the connecting air pipe 210 is welded to the inner annular tube 211. An inner air outlet 212 is opened on the outside of the inner annular tube 211, and an outer air outlet 213 is opened on the inside of the outer annular tube 209. Several outer air outlets 213 are opened at equal angles on the inside of the outer annular tube 209, and several inner air outlets 212 are opened at equal angles on the outside of the inner annular tube 211 to facilitate uniform cooling of the polyester. A water tank 214 is snapped onto the bottom of the gas collecting hood 207. An oblique air inlet pipe 215 is welded to one end face of the water tank 214. The input end of the connecting air pump 205 is electrically connected to the output end of an external power supply.

[0035] A filter assembly 3 is installed inside the water tank 214;

[0036] Filter assembly 3 includes a snap-fit ​​groove 301, a sliding groove plate 302, a filter screen 303, a sealing rubber 304, and a sealing sheet 305;

[0037] A snap-fit ​​groove 301 is provided on one side end face of the water tank 214. A sliding groove plate 302 is slidably installed on the inner side of the snap-fit ​​groove 301. An air passage groove is provided on the inner side of the water tank 214. The air passage groove is located on the inner side of the water tank 214 at the bottom position of the sliding groove plate 302 to facilitate cooling of gas. A filter screen 303 is embedded in the inner side of the sliding groove plate 302. A sealing rubber 304 is bonded to the corresponding position of one side end face of the water tank 214 and the snap-fit ​​groove 301. A sealing sheet 305 is welded to one side end face of the sliding groove plate 302.

[0038] The working principle and usage process of this utility model are as follows: First, when the screw extruder 1 extrudes polyester filaments from the extrusion head 201, the operator pulls the polyester filaments out from the space between the outer annular tube 209 and the inner annular tube 211. At the same time, the connecting air pump 205 is turned on to draw air out from the inside of the water tank 214 through the air collection hood 207 and the air inlet pipe 206. At this time, the external air will enter the bottom of the water tank 214 through the inclined air inlet pipe 215, and then enter the top of the water tank 214 through the water at the bottom of the water tank 214. Then, this air will be sucked into the inside of the connecting air pump 205 through the air collection hood 207, and then... When air passes through the water at the bottom of the water tank 214, the air is cooled and then input into the connecting air pump 205. Then, the cooled air is input into the inner side of the outer annular pipe 209 through the air outlet pipe 208, and some air enters the interior of the inner annular pipe 211 through the connecting air pipe 210. Subsequently, the cooled air is evenly sprayed onto the polyester filament from the inner air outlet 212 and the outer air outlet 213, thereby cooling the polyester filament from all directions, so that the polyester filament can be quickly formed. Then, when the polyester filament is wound up, it can prevent the deformation of the polyester filament that is not completely cooled, thus ensuring the manufacturing quality of the polyester filament.

[0039] Finally, after being cooled by water, a large amount of air passes through the filter screen 303. At this time, the humid air is filtered by the filter screen 303, thus filtering out the water vapor and impurities. This prevents the humid air from damaging the connecting air pump 205 and also prevents impurities from being sprayed onto the surface of the polyester filament, further ensuring the quality of the polyester filament. After a period of use, the sliding plate 302 can be pulled out from the inside of the snap-fit ​​groove 301. Then, the operator can clean and replace the filter screen 303. Afterward, the sliding plate 302 is pushed back into the inside of the snap-fit ​​groove 301. At this time, the sealing plate 305 will fit against one side of the sealing rubber 304, thus ensuring the airtightness of the water tank 214.

[0040] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
