Problems solved by technology
[0003] In the related art, a wire clip is usually provided in the tension maintaining mechanism, and the warp yarn is kept in tension by using the wire clip. Due to the friction between the wire clip and the warp yarn, when the warp yarn with weak strength and toughness is extracted, it is easy to break. Yarn situation, which seriously affects the yarn threading efficiency

The invention discloses a tension maintaining mechanism and a drawing-in machine. The tension maintaining mechanism comprises a first main body and a yarn guide piece, wherein the first main body is provided with an air injection hole; the yarn guide piece is fixed to the first main body and comprises a guide table; a yarn guide groove is defined by the side face, facing the first main body, of the guide table and the side face, provided with the air injection hole, of the first main body; and the air injection hole is used for injecting air to warp yarn in the yarn guide groove to enable the warp yarn to maintain tension. The air injection hole is formed in the yarn guide piece, acting force is applied to the warp yarn in the yarn guide groove through airflow injected out of the air injection hole, and the purpose of maintaining the tension of the warp yarn is achieved; and in the process, the warp yarn is not in sliding friction with other solids, the problem of yarn breakage is effectively solved, and the yarn threading efficiency is improved.
Description
Technical field [0001] The present invention relates to the technical field of textile equipment, in particular to tension retention mechanism and wearing machine. Background technique [0002] In order to make the extract mechanism to complete the extraction of the warp yarn, it is often desirable to provide a tension holding mechanism to ensure that the warp yarn after shearing the shear mechanism still has a sufficient tension. [0003] In the related art, wire clamps are typically provided in the tension holding mechanism, and the wire clamp is used to keep the tension, the friction between the wire clamp and the warp yar, is easy to break when the extraction strength and weak toughness are weak. The case of the yarn, thus seriously affecting the yarn efficiency. Inventive content [0004] The present invention is intended to address at least one of the technical problems present in the prior art. To this end, the present invention proposes a tension holding mechanism that c...
