6results about How to "Improve yarn quality" patented technology

This invention relates to a blending process for hemp fiber and sorona fiber, belonging to the technical field of blending and processing of natural fibers and bio-based elastic fibers. The blending process for hemp fiber and sorona fiber of this invention includes the following steps: raw material selection → pre-spinning process → post-spinning process → packaging. This invention solves the problems of poor spinnability, high breakage rate, and stiffness and wrinkling in pure wet-spun hemp through specific proportions and wet spinning processes, achieving high-count, stable, and high-quality production. This significantly improves spinnability, enhances yarn quality, and greatly improves hand feel and comfort, achieving high elasticity and comfort to meet user needs.

This utility model discloses a bearing assembly structure for a rotor motor, including a housing, a motor spindle, and a rotor. The housing houses a stator assembly and a rotor assembly arranged opposite to each other. The motor spindle is located inside the housing, and its output end is coaxially connected to the rotor to drive its rotation. A support base is located at the head of the housing, and a cover is mounted on the support base. The shaft of a DC brushless motor is connected to the air-jet spinning rotor assembly, transmitting the rotational power generated by the motor to the rotor. The motor speed can be precisely controlled by changing the input voltage or current to meet the needs of different spinning processes, improving production efficiency and yarn quality. It features high efficiency, fast response, and high stability. The bearing design provides a larger support area, significantly reducing vibration and offset of the motor spindle during high-speed rotation, thereby improving the concentricity and operational stability of the rotor.

The application discloses a multiple composite yarn spinning method, which adopts four single-drive rollers, a rubber roller with rubber roller sleeves added to the left and right of a back upper flat roller, and a roller with a roller sleeve added to the middle of a back lower roller, and includes single roving feeding spinning, double roving feeding spinning and triple roving feeding spinning, and single roving feeding, double roving feeding and triple roving feeding are selected respectively, each roving fed can be selected to undergo two-group independent two-zone drafting processes, and then the production of fancy yarns with different effects is realized, the variety of yarns is enriched, the added value of the yarns is improved, and in the drafting process, the drafting effect is improved and the yarn quality is improved by the additional friction force field of the middle and back upper rubber roller and the additional friction force field of the back lower roller.

This application belongs to the field of carbon fiber manufacturing technology, and discloses a carbon fiber sizing yarn bundling device, comprising: an upper roller assembly including an upper roller frame and an upper bundling roller rotatably mounted on the upper roller frame, the upper bundling roller having a first annular groove along its circumference on its surface; a lower roller assembly disposed below the upper roller assembly, including a lower roller frame and a lower bundling roller rotatably mounted on the lower roller frame, the lower bundling roller having a second annular groove along its circumference on its surface; the upper and lower bundling rollers corresponding one-to-one, and a bundling channel forming between the first and second annular grooves; a mounting frame including a sliding groove, with both ends of the upper roller frame slidably disposed within the sliding groove, and both ends of the lower roller frame fixedly disposed on the mounting frame; and a counterweight mechanism mounted on the upper roller frame. By applying pressure through the counterweight mechanism, the bundling channel can apply pressure to the sizing carbon fiber yarn during bundling, thereby squeezing out excess sizing material and compacting it. Simultaneously, during the bundling process, the upper and lower bundling rollers are rotating, resulting in low frictional resistance between them and the yarn.

This invention discloses a spring-loaded cradle, relating to the field of textile equipment technology, comprising a handle, frame, base, locking plate, positioning plate, and pressure adjusting block. The handle is rotatably connected to the frame via a handle pin, the frame is rotatably connected to the base via a first cradle shaft, and the locking plate is rotatably connected to the base via a second cradle shaft. The locking plate has a locking groove, in which a driving pin is embedded, and the driving pin is located at the end of the handle. The handle is rotatably connected to the frame via a handle pin, which is embedded in the pressure adjusting block. The pressure adjusting block has a threaded hole, in which a pressure adjusting screw is threaded. The handle cover is fixedly connected to the handle via the pressure adjusting screw. A positioning plate is also fixedly connected to the frame, and the pressure adjusting block is embedded in the handle. This mechanical structure, which features "one-click fixing and separation of fixing and pressure adjustment," allows for operation by a single person. The cradle is first fixed, and then the pressure is adjusted without interference, greatly improving installation efficiency and reducing labor intensity.

The utility model discloses a kind of beam limiting structure, comprising: main shaft, the side fixed connection of main shaft has transmission gear, main shaft sleeve is equipped with beam cylinder, the both sides of beam cylinder are respectively provided with bearing, main shaft is equipped with accommodating groove, accommodating groove is provided with elastic member, elastic member has a elastic deformation limiting portion, limiting portion is protruding from the opening plane of the accommodating groove in natural state;Wherein, the bearing of the side close to the transmission gear is arranged between the transmission gear and the limiting portion of the elastic member.The limiting portion of the elastic member continuously applies elastic pre-tightening force towards transmission gear to bearing, can automatically compensate the tiny gap generated due to manufacturing tolerance, bearing wear or vibration, ensure that beam cylinder always maintains stable axial position when high-speed operation and yarn tension change, effectively prevent its axial movement, deviation and even disengage from main shaft, greatly improve the stability of the whole process and yarn quality.
