[ technical field ] A method for producing a semiconductor device

The invention relates to a method for producing yarns, in particular to a method for producing yarns by double twisting of primary twisting and secondary twisting, and belongs to the technical field of textile machinery.

[ background of the invention ]

As is well known, the spindle of a two-for-one twister is rotated at a high speed during twisting, thereby forming a balloon. Meanwhile, electrical equipment such as a winding motor, a yarn guide motor, an overfeed motor and the like is required to be installed inside a spindle of the two-for-one twister, so that the yarn is actively wound on a yarn bobbin. Since the center of the spindle shaft needs to penetrate the yarn, the electric wire can not penetrate into the spindle directly from the center of the spindle shaft, otherwise the electric wire is wound with the yarn. How to transmit electric energy from the outside of the spindle rotating at high speed to the inside of the spindle for the use of electrical equipment in the balloon and how to accurately control electrical equipment such as a winding motor, a yarn guiding motor, an overfeeding motor and the like in the yarn balloon are technical problems in the industry.

However, the above-described conductive structure has the following problems in practical use by the present applicant: the method has the advantages of multiple components, unstable performance, high failure rate and inconvenient control.

In addition, the yarn after two-for-one twisting needs to be wound on a yarn bobbin by the combined action of a winding roller and a yarn guide head, as shown in the patent No. 201020588013.2 of the people's republic of china, which is applied earlier by the applicant. The winding forming device is arranged in a spindle surrounded by a balloon, and due to the limited installation space, the winding forming device adopts a grooved drum to guide yarns and wind and form the yarns. However, grooved-drum yarn guiding can only be used for relatively soft yarns such as cotton yarns and wool; the terylene chemical fiber filament cannot be wound by the grooved drum due to smoothness, so that the terylene chemical fiber filament has certain limitation.

Meanwhile, the bobbin creel in the yarn balloon cannot be automatically lifted along with the increase of the diameter of the yarn bobbin, so that the load on a winding roller is increased, and the energy consumption is increased; if the winding roller slips, even the yarn twist of the same yarn bobbin is inconsistent, so that the quality of the yarn is poor.

In the present embodiment, 3 primary twisting spindles 3 are provided. The primary twisting motor 2 is linked with all the primary twisting spindles 3 through a tangential belt 21, so that the transmission speeds of all the primary twisting spindles 3 are consistent, and the primary twisting motor 2 is used for performing primary twisting on the yarns. Of course, the transmission mode that the first twisting motor 2 transmits the first twisting spindles 3 one by one can also be adopted.
