Description

Technical Field

[0001] The utility model relates to the technical field of spinning machines, in particular to a spinning nozzle used in a spinning machine. Background Art

[0002] The jet vortex spinning machine uses a jet air flow to twist the fiber strips after drafting. Some free fibers at the head ends of the fiber strips are wrapped around the outside of the fiber strips for spinning. There are two types: single nozzle and double nozzle. The fiber strips are stretched thin by the drafting device and output from the front roller. They pass through the first nozzle, the second nozzle, the yarn guide hook, and the yarn roller, and are wound into a bobbin by the groove drum. The vortex rotation directions of the two nozzles are opposite, and the vortex intensity of the second nozzle is greater than that of the first nozzle, so that the twist on the yarn strip between the two nozzles can overcome the torque and resistance applied to the yarn strip by the first nozzle, and is transmitted to the jaws of the front roller. The free head ends of the twisted fibers on the periphery of the fiber strip are affected by the first nozzle and wrapped around the fiber strip in the opposite direction. The twisted fibers of the yarn core pass through the nozzle and are twisted backward, while the wrapped fibers are wrapped tighter and tighter during the reverse twisting process, providing yarn strength and cohesion.

[0003] In the prior art, a spinning machine is a machine used by people to weave silk threads, and a nozzle is often used to blow the wool thread fluffy and spray it out. When the gas blows the wool thread to move, external dust often enters the inside of the nozzle, thereby polluting the working environment inside the nozzle and may adhere to the outer surface of the wool thread, thereby affecting the subsequent weaving of the wool thread. In addition, most spinning nozzles are columnar parts, and the structural strength of this type of nozzle is poor. It lacks a good external fixing mechanism, and the textile nozzle is easily deformed and damaged when subjected to external force. For this reason, we propose a spinning nozzle for a spinning machine to solve the above problems. Utility Model Content

[0035] By means of the above structure: by setting the cooperation between the first protective tube 2, the annular air tube 3 and the second protective tube 4, the nozzle body 1 can be effectively protected to avoid damage to the nozzle body 1 caused by bumps, and then through the cooperation between the annular air tube 3, the air inlet pipe 5 and the connector 6, and through the connector 6 to the inside of the annular air tube 3, the gas will enter the interior of the nozzle body 1 through multiple air holes 103 and twist the yarn. Here, by setting the filter 7, external dust and other debris can be prevented from entering the interior of the nozzle body 1, thereby avoiding polluting the working environment inside the nozzle body 1, and can also prevent dust and other debris from adhering to the outer surface of the wool yarn, thereby affecting the subsequent weaving quality of the wool yarn.

[0036] As a preferred solution of the present invention, thread grooves are provided on the outer side of the air intake pipe 5 and the inner wall of the connecting head 6, and the two thread grooves cooperate with each other. By providing the thread grooves, the connecting head 6 and the air intake pipe 5 can be easily disassembled and assembled, and the filter 7 can be easily disassembled and assembled, which is convenient for subsequent cleaning and maintenance of the filter 7.
