Description

Technical Field

[0001] This utility model relates to the field of polyester filament production technology, specifically to a cooling device for polyester filament production. Background Technology

[0002] Polyester filament is a type of yarn made from polyester chips as raw material, using high-speed spinning to produce pre-oriented polyester yarn, which is then drawn and false-twisted. The production process of polyester filament mainly involves using a spinneret to spin the yarn out, and after spinning, a cooling device is needed to cool it down in order to maintain the shape of the polyester filament.

[0003] Currently, existing cooling devices for polyester filament production typically use air cooling, which is achieved by the airflow generated by the rotation of a fan. As the production spinning speed increases, the cooling effect on the polyester filament decreases, resulting in low cooling efficiency. Furthermore, uneven cooling may occur, which can easily lead to deformation or breakage of some polyester filaments during transport.

[0004] Based on this, the present invention designs a cooling device for polyester filament production to solve the above problems. Utility Model Content

[0014] The first guide wheel and the second guide wheel are provided at the front and rear of the water-cooling cylinder, which can guide and limit the polyester filament, so that the polyester filament passes through the center of the annular water spray mechanism inside the water-cooling cylinder.

[0015] As a preferred technical solution of this utility model, an annular air knife is provided behind the second guide wheel.

The water inlet pipe 3024 is fixedly connected to the upper end of the annular body 3021. The water inlet pipe 3024 is slidably arranged in the mounting groove 301. The outer side of the upper end of the water inlet pipe 3024 is provided with an external thread, and the locking nut 3025 is screwed onto the thread. The water inlet pipe 3024 is connected to the annular water pipe 3022.

[0033] Both ends of the water-cooled cylinder 3 are provided with sealing end plates 305, and the center of each sealing end plate 305 is provided with a through hole. A drain pipe 303 is provided at the center of the lower end of the water-cooled cylinder 3, and the bottom end of the drain pipe 303 is connected to a support base 304, which is connected to the plate body 2.

[0034] The drain pipe 303 at the lower end of the water-cooled cylinder 3 is connected to the water inlet of the cooler 4 through a connecting pipe. The water outlet of the cooler 4 is connected to the water inlet of the water tank 5 through a connecting pipe. A water pump 6 is installed at the upper end of the water tank 5. The water inlet of the water pump 6 is connected to a suction pipe, and the water inlet end of the suction pipe is located at the bottom of the inside of the water tank 5. The water outlet of the water pump 6 is connected to the water distribution pipe 7 through a connecting pipe. The water distribution pipe 7 is fixed to one side of the plate 2 through a fixed pipe seat 8. The water distribution ports on the water distribution pipe 7 are connected to the water inlet pipe 3024 on the annular water spray mechanism 302 through connecting pipes.

[0035] The cooler 4 and the water tank 5 are both fixedly mounted on the base plate of the base frame 1.

[0036] The aforementioned water-cooled cylinder 3, cooler 4, water tank 5, water pump 6, and water distribution pipe 7 are connected by connecting pipes to form a circulating cooling structure, which achieves water cooling of polyester yarn while avoiding waste of water resources, and has good practicality.

[0037] A first guide wheel 9 is provided at the front of the water-cooled cylinder 3, and a second guide wheel 10 is provided at the rear of the water-cooled cylinder 3. The first guide wheel 9 and the second guide wheel 10 are arranged on the same horizontal line.

[0038] An annular air knife 11 is provided behind the second guide wheel 10. The annular air knife 11 is fixedly installed on the upper end of the plate 2. The air inlet pipe of the annular air knife 11 is connected to the air outlet of the vortex air pump 12 through a connecting pipe.

[0043] The working principle and usage process of this utility model are as follows: In specific use, the polyester filament is passed through the through hole opened at the center of the sealing end plate 305 at both ends of the water-cooling cylinder 3, so that the polyester filament passes through the center of the annular water spray mechanism 302 inside the water-cooling cylinder 3. During the process of the polyester filament passing through the water-cooling cylinder 3, the water pump 6 starts to draw out the cooling water in the water tank 5 and delivers it to the water distribution pipe 7 through the connecting pipe. Then, the cooling water is delivered to the annular water spray mechanism 302 through the water distribution pipe 7, so that the cooling water enters the annular water pipe 3022 and is atomized and sprayed out from the multiple atomizing nozzles 3023 arranged in an annular shape, so as to perform all-round water cooling and cooling of the polyester filament. Then, the polyester filament is guided by the second guide wheel 10 to pass through the center of the annular air knife 11. The annular air knife 11 blows air around the polyester filament to achieve air cooling treatment of the polyester filament, and at the same time dries the polyester filament, so as to ensure the cooling effect of polyester filament production.
