Description

Technical Field

[0001] The utility model relates to the field of textured yarn manufacturing, and particularly to an automatic air pressure regulating pipeline for textured yarn production. Background Art

[0002] Textured yarn is a kind of silk thread formed by subjecting monofilament to a texturing process, which has good elasticity and durability. During the texturing process, the textured yarn is wound around a paper shaft or a plastic pipe. After multiple stretching and rotation, it forms a textured yarn roll through a bobbin on a winding machine. During the production process, it is necessary to transport the gas in an air compressor to the texturing machine through a pipeline. However, during the transportation process, due to the too long transportation pipeline, the pressure of the gas changes greatly, resulting in unstable air pressure in the texturing machine. Especially for the texturing machine located at the end of the transportation pipeline, the air pressure is very small, reducing the production efficiency of the textured yarn. Summary of the Invention

[0003] In order to solve certain or some technical problems existing in the prior art, the purpose of this application is to provide an automatic air pressure regulating pipeline for textured yarn production, which can automatically control the air pressure, ensure the stable pressure of the gas transported in the pipeline, and improve the production efficiency.

The electric pressure regulating valve can automatically control the air pressure to ensure the stable pressure of the gas transported in the main pipeline; when the main pipeline is damaged and needs to be repaired, there is no need to stop work. Just close the main pipeline and open the valve on the branch pipeline to continue working; the temperature sensor can timely transmit the temperature signal to avoid the too high temperature of the transported gas affecting the work of the texturing machine.

[0005] Preferably, a protective tube is sleeved on the transmission line of the temperature sensor. The protective tube adopts an L-shaped structure, and the protective tube is connected to the main pipeline or the branch pipeline through a plurality of fixing devices. The gas transported by the main pipeline or the branch pipeline has a certain temperature. The protective tube is used to protect the transmission line to avoid the direct contact between the transmission line and the main pipeline or the branch pipeline, resulting in damage and deformation.

[0006] Preferably, the fixing device is formed by winding iron wire into an 8-shaped structure, with one end sleeved on the protective tube and the other end sleeved on the main pipeline or the branch pipeline. It is convenient to use and has a low cost.

[0007] Preferably, the fixing device adopts a detachable connector, which includes a left connector and a right connector which are mutually connected at the bottom, the left connector is provided with a left clamping groove, the right connector is provided with a right clamping groove which cooperates with the left clamping groove to clamp the protective tube, the right connector is provided with a clamping belt which is detachably connected to the left connector, and the clamping belt is sleeved on the main pipe or the branch pipe.

After the cassette is sleeved on the main pipe or the branch pipe, the female buckle and the sub-buckle are used for buckling, which has a simple structure and convenient connection.

[0009] Preferably, a connecting column is provided on the connecting plate, and the end of the protection tube is in contact with the connecting column, so as to avoid shaking of the protection tube and ensure accurate measurement of the temperature sensor.
