Nozzle

Abstract

The invention relates to the technical field of cloth dyeing and finishing, and discloses a nozzle. The nozzle comprises an overflow pipe and a jet pipe; the overflow pipe penetrates through the jet pipe in the axial direction of the jet pipe; the two ends of the jet pipe are in sealed connection with the overflow pipe respectively; at least one overflow port is formed in the area, corresponding to the jet pipe, of the overflow pipe; and at least one water outlet is formed in the jet pipe. During actual use, liquid enters the overflow pipe and then enters a water containing cavity from each overflow port; the liquid in the water containing cavity overflows from each water outlet after reaching a certain amount, so that the pressure intensity of the liquid sprayed from each water outlet isthe same, and the flow speed of the liquid sprayed from each water outlet is the same; therefore, when the nozzle is applied to an open-width sand washing machine, the acting force of fluid sprayed out of different water outlets on cloth is the same, the cloth is always in an open state and cannot be blocked in a flow channel, the overall splitting degree of the cloth is the same, and the consistency after sand washing is high.

Description

technical field [0001] The invention relates to the technical field of cloth dyeing and finishing, in particular to a nozzle. Background technique [0002] In the technical field of cloth dyeing and finishing, in order to make the cloth smooth and fluffy, a drum-type sand washing machine is often used to sand-wash and open the cloth. However, the drum-type sand washing machine cannot meet the production demand due to the small amount of sand washing, the uneven friction force between cloth and cloth in the sand washing process, and the poor consistency of the cloth after sand washing. If the open-width sand washing machine is designed to sand-wash the cloth, the following technical problems need to be solved: first, the cloth needs to be in an open state along the width direction of the cloth when the cloth is conveyed in the open width; Make sure that the cloth receives the same fluid force as it flows, otherwise the friction between different areas of the cloth and the fl...

Problems solved by technology

The drum-type sand washing machine cannot meet the production needs due to the small amount of sand washing, the uneven friction force between the cloth and the cloth during the sand washing process, and the poor consistency of the cloth after sand washing.

If the open-width sand washing machine is designed to sand-wash the cloth, the following technical problems need to be solved: first, the cloth needs to be in an open state along the width direction of the cloth when the cloth is conveyed in the open width; Make sure that the cloth receives the same fluid force as it flows, otherwise the friction between different areas of the cloth and the fluid will be uneven, resulting in poor consistency of the cloth after sand washing

[0003] At present, in the cloth dyeing and finishing equipment, most of the nozzles with only one nozzle are used as the power source to eject the fluid, and the single-port nozzle cannot be applied to the open-width sand washing machine due to the following reasons. Different fluid flow rates will result in different fluid force on the cloth and the corresponding area of ​​the fluid ejected from the single-port nozzle, which not only affects the consistency of cloth sand washing, but also makes the cloth shrink to the point where the force is the largest, making the The cloth is no longer fully stretched, and in severe cases, the cloth will be blocked in the runner
