[0002] With the development of economy, people's living standards are gradually improving, the clothing industry is developing rapidly, and the demand for various clothing is also increasing. Yarn is indispensable in the production of clothing.

[0003] The two-for-one twister is a twisting device that can achieve two twists in one turn. The twisting efficiency is doubled compared to traditional twisting equipment, the winding capacity is increased, and there is no joint in 10,000 meters. The twisting quality is greatly improved, and the lower layer height makes it particularly suitable for operation. The two-for-one twister can bond two or more single yarns into ply yarns by twisting, and enhance the performance of the original yarn. However, it is difficult for the current two-for-one twister to twist multiple yarns at the same time. If the materials of the yarns are different, the yarns will be out of sync or stuck during the twisting, which makes it difficult to meet the use requirements. Therefore, it is necessary to improve it. Summary of the invention

[0004] The present invention provides a superimposed multi-yarn two-for-one twisting machine which can simultaneously twist yarns of multiple different materials, has a high degree of design freedom, can freely install different numbers of yarn tubes according to needs, has high working efficiency, and is easy to operate; it solves the technical problem that the current two-for-one twisting machine in the prior art has a single structure and can only twist a single yarn. If the materials of the two yarns are different, it is difficult to use one yarn tube to twist the two yarns together, and the actual use requirements cannot be met.

[0005] The above technical problem of the present invention is solved by the following technical scheme: a superimposed multi-yarn two-for-one twisting machine, including a machine tool, a plurality of detachable winding drums are arranged at the bottom of the machine tool, a plurality of driving bases are arranged at intervals on the machine tool, each driving base is provided with a plurality of two-for-one twisting yarn drums that can be longitudinally stacked, and two adjacent two-for-one twisting yarn drums are fixedly connected by a positioning structure. When in use, different numbers of two-for-one twisting yarn drums can be installed according to needs, and yarns of different materials are wound on the upper and lower two-for-one twisting yarn drums. When installing, the bottom two-for-one twisting yarn drum is fixed on the driving base, and the other two-for-one twisting yarn drums are installed on the top. When installing, the upper and lower two-for-one twisting yarn drums are fixed by the positioning structure. When the driving base is turned on, the driving base will drive the upper two-for-one twisting yarn drum to rotate at the same time, and the yarn is drawn out from the two-for-one twisting yarn drum, and extends downward through the central cavity of the two-for-one twisting yarn drum upward. With the rotation of the driving base, the yarns of the upper and lower two-for-one twisting yarn drums are twisted together under high-speed rotation and centrifugal action, and the twisted yarns are wound and stored on the winding drum.

During installation, the positioning ring of the upper two-for-one twisted yarn drum can be inserted into the lower one to ensure the positioning of the upper and lower two-for-one twisted yarn drums during installation.

[0007] Preferably, each of the installation grooves has a hemispherical positioning groove formed at the bottom, and each positioning ring has a spherical positioning protrusion formed at the bottom. After installation, the positioning protrusion at the bottom of the positioning ring will also be inserted into the positioning groove, further ensuring the positioning and fixation of the upper and lower double twisted yarn drums, avoiding the situation that the upper and lower double twisted yarn drums are not installed properly and are unstable during operation.

[0008] Preferably, the two adjacent positioning rings are matched with the mounting grooves through threads. During installation, the bottom two-for-one twisted yarn drum is fixed on the driving base, and then the other two-for-one twisted yarn drum is installed on the top. During installation, the positioning ring of the upper two-for-one twisted yarn drum is screwed into the mounting groove of the lower two-for-one twisted yarn drum.
