The bowl and flexible wire clothing are composed of the above copper needle base cloth and plants. Grinder A spinning machine that turns fiber strands into rovings. The main function is to draft and twist, and to wind the roving into a certain package to meet the processing requirements of the spinning frame.
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).
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. From vulcanized rubber cloth, cotton fabric, copper glue with multi-layer mixed linen fabric. Base fabric structure 2 cylinders, doffer surface in rubber (CYCLCC), 5 rubber (YCLCCC), five; flat card clothing rubber surface with five, eight rubber surfaces (YCCLCCCGC) and seven rubber suppliers (YCCLCCCC), etc.
Suppliers should base fabric strength, small, long-term use elongation not loose, and flexible carding force, due to the point of action Hang deflection H to quickly restore the original position. The strength, elasticity and recovery of the multi-layer convergent thicker base fabric are good. There are thick and thin needles, various round, triangular, oblate, rectangular, etc. cross-sections.
Angular distribution at the U-shaped needle and implanted in the base fabric. There are three ways to needle g twill and satin stripes, as shown in Figure 3-31. The method is named 6X cylinder (3+2) satin, 6 means 6 transverse threads per 50.8mm, with longitudinal (3+2) = 5 stitches, 6×4 Doffer represents the horizontal strip 6 every 38.1mm line 0.6, there are four longitudinal stitches; ! 5233 cover twill, 4 represents four horizontal lines every 25.4mm, six longitudinal.
Satin cylinders are generally used to increase lateral density; Doffer uses stripes; twill covers. The flat card clothing of the carding machine is divided into double row and single row city. Type 702 cover is a double-row cover, from fH1 to 10 pins, 8 pins in the hollow, and 10 pins in the back row.
There is no gap in the middle of the card clothing company is 7 mm. ) The fork row cover can play the carding function of the rear part of the comb surface. If there is a gap in the middle, the accumulation of short-pile hand impurities can help to eliminate other harmful defects in the cover and flowers. In order to reduce the effect of combing, the steel needle is generally bent into a knee shape.
However, the bending moment of the colored steel needle is large, and the deformation is small after being stressed, so straight-footed steel needles such as type 702 and type 672 flat clothing can be used. The vertical height of the pot needle, including the part inserted into the base fabric, is generally 8-9 mm. The tip of the needle is generally ground with pressure and side galleries, and the tip of the needle is shaped into a knife to make the tip sharp.
Type 702 and 672 flat card clothing, the steel wire is fan-shaped and circular, the section is cut into a wedge, the wedge angle is 22, and the tip is very sharp. But the tip of the cut is no longer flat. The flatness of the needle surface is poor.
50-60 gauge carbon dowel wire or 65 gauge dowel wire. The needle tip hardness is hrc58-62, and the quenching depth is i-i. .5mm to make it wear-resistant.
