[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] This utility model provides a technical solution:

[0035] Please refer to Figure 1 to Figure 4A drawing device for processing polyester fibers includes a fixed base plate 1, an air-cooling component 3 installed on the top of the fixed base plate 1, and a distance adjustment component 4 provided on one side of the air-cooling component 3. Multiple cooling rollers 2 and multiple take-up shafts 5 are rotatably installed on the inner side of the distance adjustment component 4. The take-up shafts 5 and the cooling rollers 2 are parallel to each other and are arranged in a one-to-one correspondence with each other.

[0036] The air-cooled assembly 3 includes a cooling ring 308 that is adapted to the height of the take-up shaft 5, and a breathable mesh 309 is fixedly installed inside the cooling ring 308. A support rod 305 is fixedly connected between the cooling rings 308, and an air supply duct 307 is fixedly connected to one side of the support rod 305.

[0037] The support rod 305 has a hollow structure and is connected to the air supply pipe 307. The air supply pipe 307 is a plastic corrugated pipe. The end of the air supply pipe 307 is fixedly connected to the cold air box 310, and the side wall of the cold air box 310 is fixedly installed with a cold air fan 306. The bottom of the support rod 305 is fixedly connected to the guide slider 304, and the connection between the guide slider 304 and the fixed base plate 1 is provided with a guide groove 302. The inside of the guide slider 304 is connected to the guide screw 303 through a threaded sleeve, and one end of the guide screw 303 is fixedly connected to the power output end of the guide motor 301.

[0038] By adopting the above technical solution, the polyester fiber passes through the cooling ring 308, passes through the bottom of the corresponding cooling roller 2, wraps around the top of the take-up shaft 5, and is wound around the outside of the take-up shaft 5. When passing through the cooling ring 308, the cold air fan 306 can be started. The cold air fan 306 sends cold air through the cold air box 310 into the air supply pipe 307, and then through the air supply pipe 307 to the inside of the hollow support rod 305, and then sequentially to the inside of the cooling ring 308. The inside of the cooling ring 308 is provided with an annular breathable mesh 309, which can provide circumferential air supply and cooling to the polyester fiber inside, thereby making the cooling of the polyester fiber more uniform.

[0039] Simultaneously, while the polyester fiber is being wound up, the guide motor 301 can be started. The guide motor 301 drives the guide screw 303 to rotate, which in turn drives the guide slider 304 on the guide screw 303 to slide inside the guide groove 302, thereby driving the cooling ring 308 to reciprocate. In conjunction with the winding shaft 5, the winding of the polyester fiber can be achieved.

[0040] Specifically, such as Figure 4As shown, the distance adjustment assembly 4 includes two sets of slidable limiting sliders 403. Limiting grooves 401 are provided at the connection between the limiting sliders 403 and the fixed base plate 1. A bidirectional lead screw 404 is connected internally to the two sets of limiting sliders 403 via a threaded sleeve. One end of the bidirectional lead screw 404 is fixedly connected to the power output end of a lead screw motor 405.

[0041] A movable support 402 is fixedly installed on the top of the device. The cooling roller 2 is rotatably installed inside one set of movable supports 402, and the winding shaft 5 is rotatably installed inside another set of movable supports 402. The cooling roller 2 has a hollow structure, and both ends of the cooling roller 2 are provided with pipe connection ports 6. One end of the winding shaft 5 is fixedly connected to the power output end of the winding motor 7.

[0042] By adopting the above technical solution, one of the pipe connection ports 6 is a water inlet and the other is a water outlet. Cold water is sent to the pipe connection port 6 through the water inlet and enters the cooling roller 2. When the polyester fiber passes through the cooling roller 2, it can be cooled and cooled down by the cooling roller 2. After absorbing heat, it can be discharged outward from the water outlet. The lead screw motor 405 is started, which drives the bidirectional lead screw 404 to rotate. When the bidirectional lead screw 404 rotates, it can cause the two sets of limit sliders 403 to move in opposite directions, thereby adjusting the distance between the two sets of limit sliders 403.

[0043] Working principle: Polyester fibers pass through the cooling ring 308, around the bottom of the corresponding cooling roller 2, around the top of the take-up shaft 5, and are wound around the outside of the take-up shaft 5. When passing through the cooling ring 308, the cold air fan 306 is activated, and the cold air fan 306 sends cold air through the cold air box 310 into the air supply pipe 307, and then through the air supply pipe 307 to the inside of the hollow support rod 305, and then sequentially to the inside of the cooling ring 308. The inside of the cooling ring 308 is equipped with an annular breathable mesh 309, which allows for circumferential air supply and cooling of the polyester fibers inside, making the cooling of the polyester fibers more uniform. One of the pipe connection ports 6 is a water inlet and the other is a water outlet. Cold water is sent to the pipe connection port 6 through the water inlet and enters the cooling roller 2. When the polyester fibers pass through the cooling roller 2, they are cooled and cooled again by the cooling roller 2. After absorbing heat, they can be discharged outward from the water outlet. The lead screw motor 405 is activated. It can drive the bidirectional lead screw 404 to rotate, and when the bidirectional lead screw 404 rotates, it can cause the two sets of limit sliders 403 to move together.

[0044] The two sets of limit sliders 403 are moved in opposite directions to adjust the distance between them. At the same time, while the polyester fiber is being wound up, the guide motor 301 can be started. The guide motor 301 drives the guide screw 303 to rotate, which in turn causes the guide slider 304 on the guide screw 303 to slide inside the guide groove 302, thereby driving the cooling ring 308 to reciprocate. In conjunction with the winding shaft 5, the winding of the polyester fiber can be achieved.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
