The invention discloses an automatic silk reeling machine headstock brushing end cocoon feeding device and a control technology thereof. The cocoon feeding device comprises a brushing-picking end cocoon without end cooling mechanism arranged on an end picking pot (10) and a mixed cocoon conveying mechanism connected with the brushing-picking end cocoon without end cooling mechanism, the output side of the mixed cocoon conveying mechanism is arranged on a high-temperature cocoon feeding opening of an end brushing pot (2), and a water flow system cooperates with the end picking pot (10) and thebrushing-picking end cocoon without end cooling mechanism; the control technology comprises the following steps that 1) the brushing-picking end cocoon without end cooling mechanism cools brushing-picking end cocoons without ends in the end picking pot (10); 2) the mixed cocoon conveying mechanism mixes the cooled brushing-picking end cocoons without ends and reeling silk dropping end cocoons andconveys the cooled brushing-picking end cocoons without ends and the reeling silk dropping end cocoons to the end brushing pot (2) for end brushing; 3) new cocoons are supplemented to the end brushingpot (2); the cooled brushing-picking end cocoons without ends in the end picking pot and the reeling silk dropping end cocoons are mixed and added in the end brushing pot, and therefore the stabilityof the brushing end cocoon setting quantity is improved, and the temperature fluctuation is reduced.

The invention discloses an electric pneumatic spindle, belongs to the field of two-for-one twister spindles, and solves the problems of low automation level and no synchronous cooperation of electric and pneumatic yarn guide functions of an existing two-for-one twister spindle. The electric pneumatic spindle comprises a rotor assembly, wherein the rotor assembly comprises a rotor motor and a spindle blade fixedly connected with a rotor iron core on a rotor motor, and further comprises a pneumatic yarn threading device arranged in the spindle blade; the pneumatic yarn threading device comprises a straight air inlet channel, an oblique air inlet channel, a yarn guide cavity, a yarn guide assembly arranged in the yarn guide cavity, and a straight yarn inlet channel; the straight air inlet channel is formed in one end, fixedly connected with the rotor iron core, of the spindle blade; the oblique air inlet channel is connected with the straight air inlet channel; and the straight yarn inlet channel is formed in one end, extending into a yarn pipe assembly, of the spindle blade. According to the electric pneumatic spindle, the motor-driven and pneumatic yarn guide functions of the existing two-for-one twister spindle can be well combined, so that automated start-stop and yarn guiding are realized and the development requirements of automated management of modern spinning and weaving workshops are met.

The invention provides a threading machine used for inserting a steel wire into a core and a threading method. The threading machine comprises a frame having a first end and a second end, a feeding device arranged at the first end of the frame, a material clamping device connected with the feeding device, a steel wire uncoiling and coiling device arranged at the second end of the frame, a threading device capable of moving between the first end and the second end, a wire clamping device arranged at the first end of the frame, and a burning device used for heating the steel wire dragged by the threading device, wherein the material clamping device and the wire clamping device can selectively align at the position of the threading device. The threading machine is advantaged in that material conveying is realized through the feeding device, the core is clamped through the material clamping device, the steel wire is released by the steel wire uncoiling and coiling device, the steel wire is dragged by the threading device to realize threading, the steel wire is clamped by the wire clamping device, the steel wire is heated by the burning device, the threading machine used for inserting the steel wire into the core is commonly formed through the parts, compared with a traditional manual threading method, the threading machine further is more reliable, and threading efficiency is substantially improved.
