Cross air blowing device

Abstract

The invention provides a cross air blowing device. The device comprises an upper-layer door, a lower-layer door, an air inlet and an air outlet, wherein the upper-layer door is mounted at one end of a frame, and one end of the upper-layer door is connected with one end of the lower-layer door; the lower-layer door is mounted at the other end of the frame; the air inlet is arranged at the other end of the frame; the air outlet is arranged at the other end of the upper-layer door, and the lower-layer door is a sealing door. Thus, the lower-layer door adopts a sealing structure, so that the cooling airflow direction in the position where the lower-layer door and a spinning path opening cannot be changed, the condition that tows swing in the position where the lower-layer door and the spinning path opening are connected due to airflow impact is avoided, bending, breakage and adhesion of the tows in the position are avoided, and the product quality is improved.

Description

technical field [0001] The invention belongs to the technical field of spinning, in particular to a side blowing device. Background technique [0002] In the production of split fiber master filament spinning, the melt is sprayed out from the spinneret hole and enters the side blowing device for cooling, so that the tow is cooled and split, and the next production process is carried out. [0003] In the prior art, when the side blowing device cools the tow, at the junction of the side blowing and the spinning shaft, due to the sudden change of the wind direction of the cooling wind, the tow bends, swings, intertwines and sticks here, and the spinning Increased broken wires, difficult wire separation, high raw material consumption, and reduced product quality. [0004] Based on this, the present invention provides a side blowing device for solving the above-mentioned problems in the prior art.

Problems solved by technology

[0005] Aiming at the problems existing in the prior art, the embodiment of the present invention provides a side blowing device, which is used to solve the problems at the junction of the side blowing and the spinning shaft when the side blowing device in the prior art cools and separates the tow. Due to the sudden change of the wind direction of the cooling wind, the tow is bent, broken or stuck here, which leads to the difficulty of separating the filaments and the decline in product quality.
