Description

Technical Field

[0001] This utility model relates to the field of polyester filament drying, and in particular to a polyester filament drying device. Background Technology

[0002] Solution-dyed recycled high-strength polyester FDY yarn is produced by combining recycled polyester chips with solution-dyed masterbatch and melt spinning technology for high-strength fibers. The raw materials for producing polyester yarn are granulated and wet-sliced ​​before being heated in a screw extruder and spun into yarn. The shaped polyester yarn needs to be sprayed with water or cooled with water to quickly set its shape. After cooling, a drying device is used to dry the damp polyester yarn.

[0003] Existing drying equipment first brings the damp polyester yarn into contact with the desiccant in the drying chamber to absorb and remove the moisture from the polyester yarn. Then, it uses a compression drying chamber to squeeze out the moisture from the center and spread it to the surface. Finally, it uses air to quickly remove the moisture, making the polyester yarn drier.

[0004] However, during the drying process, the polyester filaments are always tightly packed together, making it impossible for the hot air to pass evenly through the tightly packed polyester filaments, resulting in poor drying effect.

[0005] Therefore, it is necessary to provide a new drying device for polyester filaments to solve the above-mentioned technical problems. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model provides a drying device for polyester yarn, which solves the problem that when polyester yarn is dried, the polyester yarn is always densely squeezed together, making it impossible for hot air to pass evenly through the squeezed polyester yarn, resulting in poor drying effect.

[0007] The polyester filament drying device provided by this utility model includes a cooling water tank, a first guide roller is movably arranged, and a plurality of ventilation pipes with supporting legs fixed at the bottom are arranged at intervals on one side of the cooling water tank. A hot air outlet is connected to the top of the ventilation pipe.

[0008] In a preferred embodiment, multiple pairs of second guide rollers are spaced apart above the ventilation duct.

[0009] In a preferred embodiment, a connecting pipe is provided on one side of the cooling water tank, the connecting pipe is connected to the ventilation pipe, and an air inlet is provided on the connecting pipe.

[0010] In a preferred embodiment, a lifting seat is provided above the cooling water tank, an mounting plate is installed at the bottom of the lifting seat, and a rubber wiper is provided at the bottom of the mounting plate.

[0011] In a preferred embodiment, a sliding column and a lead screw are spaced apart above the cooling water tank. Both the sliding column and the lead screw pass through the lifting seat. The sliding column is slidably connected to the lifting seat, and the lead screw is threadedly connected to the lifting seat.

[0012] The bottom of the sliding column is fixed to the cooling water tank, and the bottom of the lead screw is movably connected to the surface of the cooling water tank.

[0013] In a preferred embodiment, a hexagonal block is fixed to the top of the lead screw, and the lead screw is galvanized.

[0014] The beneficial effects of this utility model are:

[0015] When this drying device is in use, after the polyester yarn has been cooled from inside the cooling water tank, it will pass through the first guide roller and the second guide roller in sequence. Before passing through the first guide roller, the rubber scraper will remove the moisture from the surface of the polyester yarn, so that the hot air sprayed from the hot air outlet can dry the surface of the yarn.

[0016] Using a wrench to turn the hexagonal block drives the lead screw to rotate. The lifting seat can be moved up or down to adjust the pressure of the rubber wiper blade on the polyester yarn, ensuring wiping efficiency while avoiding damage to the polyester yarn. Attached Figure Description
