Device for preventing yarn bottom falling of two-for-one twister in processing process

Abstract

The invention discloses a device for preventing yarn bottom falling of a two-for-one twister in the processing process. The device structurally comprises a spindle, a bobbin and a bottom falling preventing cushion. The spindle and the bobbin are located on the same horizontal plane, the spindle and the bobbin are connected, and the bottom falling preventing cushion is arranged at the bottom of the spindle. The bottom falling preventing cushion is composed of a gasket and a center hole. The gasket and the center hole are round, the gasket and the center hole are concentric circles, the gasket is provided with the center hole, the diameter of the inner circle of the gasket is slightly smaller than the outer diameter of the bobbin, and the diameter of the outer circle of the gasket is equal to the inner diameter of the spindle. The thickness of the gasket is 4 mm, the gasket is a soft sponge, and the bobbin is used for storing yarn. The sponge is cushioned into the bottom of the spindle, the phenomenon of yarn bottom falling is effectively avoided, yarn twisting production is smoothly carried out, and meanwhile the product quality is guaranteed.

Description

technical field [0001] The invention relates to a device for preventing yarn from falling to the bottom in the processing process of a two-for-one twister, belonging to the field of two-for-one twisters. Background technique [0002] The two-for-one twister is a kind of twisting equipment, which can realize two twists in one turn, and the twisting efficiency is doubled compared with traditional twisting equipment. The package capacity is increased, 10,000 meters without joints, the twisting quality is greatly improved, and the lower layer height is especially suitable for operation. [0003] In actual production, we are twisting 300D / 96F polyester DTY dyed double-ply yarn. When the spindle speed is 3200 rpm and the twist is 150 twists / m, the air circle is unstable, and the self-stop probe shakes up and down. The ingot breakage rate reaches 1 time / 5 minutes, and the twist unevenness rate reaches 15%. After inspection, it was found that the reason for the above phenomenon wa...
