Multi-section side-blowing device for spinning

Abstract

The invention provides a multi-section side-blowing device for spinning. The multi-section side-blowing device for spinning comprises a side-blowing box, multiple side-blowing rectifying devices and an air-blowing channel. A side-blowing pipe is fixed in the side-blowing box. The side-blowing rectifying device comprises an air inlet pipe, an air inlet valve, an air distributing cavity, an air baffle and an air distributing plate. The air inlet pipe is provided with an air inlet and an air outlet. The air inlet is connected with the side-blowing pipe. The air outlet is connected with the air distributing cavity. The air inlet pipe is further provided with the air inlet valve. The air outlet of the air inlet pipe is provided with the air baffle. The air-blowing channel is separated from theside-blowing rectifying device through the air distributing plate. Side-blowing of the multi-section side-blowing device adopts multi-section inlet air, and each section of an air quantity can be independently controlled, so a technical defect that the air quantity of each point of the side-blowing cannot be controlled is solved.

Description

technical field [0001] The invention relates to the technical field of spinning, in particular to a multi-stage side blowing device for spinning. Background technique [0002] In the production of nylon 6 monofilament spinning, the melt is sprayed out from the spinneret hole and enters the side blowing device for cooling. Because the fiber is thicker, cooling is difficult, so a higher side blowing window is required. In the prior art, the side blowing is single-stage blowing, and the air volume at each point varies greatly, resulting in difficulties in production and a decline in product quality. In the prior art, the door for side blowing is single-layer, and a movable shelf is needed when replacing the spinning assembly and cleaning the spinneret surface, and the operator stands on the shelf to work, which is prone to personal safety accidents; in the prior art, the side The blowing door is a louver-type air-permeable structure. Due to the sudden change of the wind direct...

In the prior art, the side blowing is single-stage blowing, and the air volume at each point varies greatly, resulting in production difficulties and product quality decline

In the prior art, the door for side blowing is single-layer, and a movable shelf is needed when replacing the spinning assembly and cleaning the spinneret surface, and the operator stands on the shelf to work, which is prone to personal safety accidents; in the prior art, the side The blowing door is a louver-type air-permeable structure. Due to the sudden change of the wind direction of the cooling wind at the junction of the side blowing and the spinning shaft, the filament bundles are bent, swayed, intertwined and bonded here, and the spinning is broken. Silk increases, raw material consumption is high, product quality declines
