Description

Technical Field

[0001] The utility model belongs to the technical field of yarn drying, in particular to an environmentally friendly polyester yarn drying mechanism. Background Art

[0002] During the production process, environmentally friendly polyester yarn may contain a certain amount of moisture due to dyeing and rinsing. If this moisture is not removed promptly, it will affect the yarn quality and the efficiency of subsequent processing. Drying removes moisture from the yarn to ensure dryness and stability. Drying also improves the softness and comfort of the yarn, making it more in line with market demand.

[0003] Before drying, polyester yarn undergoes treatments such as straightening and crimping. These pretreatment steps ensure that the yarn is evenly heated during the drying process, preventing quality issues. Furthermore, the drying time of polyester yarn must be controlled; too long a drying time may result in overdrying, while too short a drying time may result in incomplete drying.

[0041] Example 2

[0042] Combine Figure 1 and Figure 3 As shown, in order to solve the problem of yarn drying time, this solution provides a hot air drying device 7 for contacting with the yarn to perform segmented drying.

[0043] like Figure 3 As shown, the hot air drying device 7 includes a positioning rod 71, a guide wheel 72 and a hot air blower 732. The positioning rod 71 is arranged on one side of the drive box 3. The positioning rod 71 is arranged parallel to the side of the guide sleeve 62 away from the take-up roller 4. The free end of the positioning rod 71 is provided with a guide wheel 72.

The drying hole 74 is located on the inner wall of the guide wheel 72 close to the side of the positioning rod.

[0045] As a preferred embodiment: an extension seat 611 is also installed on the side of the fixed seat 61 close to the take-up roller 4, and a limiting roller 612 is installed above the extension seat 611. The height of the limiting roller 612 is located between the take-up roller 4 and the guide sleeve 62.

[0046] As a preferred embodiment: the positioning rods 71 are arranged in multiple groups, preferably three groups distributed in a triangular shape, the side wall of the drive box 3 is provided with a slot, the positioning rods 71 are installed in the slot through a fixing part 77, the main pipe 75 is a hard pipe, the main pipe 75, the heater 731, and the fan 732 are installed and fixed on the inner wall of the drive box 3, and the branch pipe 76 is a flexible telescopic pipe, which can be adjusted automatically according to the position of the positioning rod 71.

[0047] When using this structure, the fan 732 directs the hot air heated by the heater 731 into the main pipe 75 and the branch pipe 76 in sequence. The drying temperature is preferably 70-90°C, and the drying holes 74 exhaust the hot air from one side of the guide wheel 72.
