In modern cards, the card and silk ensembles are still used. The structure of the double twisting unit of the double twisting machine mainly includes the spindle braking device, the spindle part of the double twisting machine, the yarn winding device, and the special device of the double twisting unit. Carding machines are used to process cotton fibers and chemical fibers and belong to textile machinery.
According to the spinning process, carding is an important process. The front process of the carding machine is the opening and cleaning machine, and the latter process is the drawing frame (carding process) or the sliver coiler (combing process). Special equipment for the textile industry on the winder.
As the last process of spinning and the first process of weaving, winding is the link between the past and the next.“bridge”Therefore, it occupies an important position in the textile field. The comprehensive line has its advantages, mainly in: 1. Card holes of various sizes and shapes for various requirements. 2. The carding machine can be larger, suitable for coarse sand.
The synthetic heel has a sharp edge and less head breakage. 4. Si's steel heald is only 1/2.5 lighter than the heald frame and wears less. Huddle's slender observation eliminates clear warp, large gaps in warp.
Grob's development is mainly based on China's international social standards 150364 and 365 to produce combined silk healds. There are several types of heddle eyes. The twisting eye is generally hexagonal, providing a needle-like structure channel that is unfavorable for the warp direction, and we will saw the warp soon.λThe twisting technology part near the heald eye of the solder g also influences the free selective sliding of the adjacent detection yarn.
Although my country's international environmental standards still guarantee this kind of comprehensive eye, Grob does not recommend passing this kind of comprehensive eye. Soldering ring eyelets are often used abroad, which can prevent the problem of solder sawing into the warp. Flat groove 5R type welding ring eye is suitable for weaving yarn, fine cross yarn and high fabric, and it is not afraid of warp wear after heat treatment.
The R-type welding ring eye has a thin groove on the outer edge of its base, which makes the combination with the heald firmly. R-type welding penalty; the inner side of the eye is round, and the damage of the coarse yarn is not burned in the time volume of the yarn, such as xanthogenous fiber abdominal distension. The GROB company produces healds with maintenance, the stranded wire part is not welded with eyelets, and the untwisted heald frame is untwisted at the time of election.
If using a perster automatic drawing-in machine, the healds must be improved, and the twisting technique part of the upper heald ear must be at least 5.5 mm long, starting with the heald eye: yes. To accommodate the separation of the integrated filaments, the lower ear should be color-coded. Stick 19 is the grob and silk integrated child welding ring eye.
The heavy hammer used for jacquard treatment should be hung under the treatment with the ring. Grob Company also has a method that does not need to be broken, the minister is connected to the lower integrated ear and any clearance is poured, and there is any sound and movement on the side during movement, which can greatly extend the service life of the integrated lead screw on the hammer head, suitable for High-speed carding machine.
