Description

Technical Field

[0001] This utility model relates to the field of drying equipment technology, specifically to a high-efficiency drying device for polyester filament production. Background Technology

[0002] Polyester is characterized by its resistance to chemicals and frequent washing, reducing fading and discoloration of clothing. Polyester is an important type of synthetic fiber and is the commercial name for polyester fiber in my country. It is a fiber-forming polymer—polyethylene terephthalate (PET)—obtained from purified terephthalic acid (PTA) or dimethyl terephthalate (DMT) and ethylene glycol (EG) through esterification or transesterification and polycondensation reactions. The fiber is then spun and post-treated.

[0003] A search revealed that CN223304703U describes a drying device for polyester filaments. This device includes a frame with a drying chamber fixedly mounted on it. A turbine fan, communicating with the inner cavity of the drying chamber, is located at the upper end of the drying chamber for upward exhaust. A heating wire section, also communicating with the inner cavity of the drying chamber, is fixed at the lower end of the drying chamber. The heating wire within this section heats the filaments as air passes through. Inlet and outlet ports are located on the left and right sides of the upper end of the drying chamber, and guide rollers are rotatably mounted within these ports to guide the polyester filament bundles. This invention provides a more uniform drying effect. Furthermore, by adjusting the position of the drying traction rollers, the time it takes for the polyester filament bundles to pass through the drying chamber can be adjusted to meet different drying humidity requirements. An up-and-down movable second slider reduces excessive stretching of the polyester filament bundles during movement.

[0004] However, the above-mentioned drying device still has the following problems: the drying device cannot squeeze out the moisture contained inside the polyester filament before drying, thus reducing the drying efficiency of the polyester filament, and the drying device cannot adjust the heating area of ​​the polyester filament, thus affecting the drying effect of the polyester filament.

The second motor 95 drives the worm gear 94 and worm wheel 92 to mesh, causing the drive rod 93 to rotate the drive roller 12. The friction between the drive roller 12 and the polyester filament pulls the polyester filament forward. The support spring 62 pushes the movable baffle 63 downward, which in turn drives the support rod 64 to push the extrusion roller 20 downward, squeezing the polyester filament onto the dewatering roller 19. With the traction of the polyester filament, the extrusion roller 20 and the dewatering roller 19 can squeeze out the water inside the polyester filament. The squeezed water is guided into the water collection tank 17 through the water collection hopper 4 and the drain pipe 5. The first motor 72 is controlled to drive the threaded rod 73 to rotate, so that the threaded rod 73 and the lifting rod 74 can perform threaded transmission, which can stretch the middle part of the polyester filament, increase the heat-receiving area of ​​the polyester filament, and improve the drying efficiency.
