In order to ensure the uniform distribution of warp yarns, the box gap must be uniform, and under the current development conditions of information technology in our country, it is very difficult to completely achieve this, because the thickness of the pin and the diameter of the pin wire have a tolerance. During the spinning process of the spinning frame, the semi-finished roving or sliver is drafted, twisted, and wound into a spinning machine. The combed sliver and the needle-carding machine combine the sliver, the needle row is drafted to improve the sliver structure, and the roving is further spun into spun yarn on the ring spinning frame, which is the main spinning machine. 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.
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. If a box with a length of one meter and a street piece of 3,000 pieces is braided, the thickness tolerance of the knot piece is 0.01 mm, and the accumulated tolerance of the gold length will reach 30 mm.
The accumulation tolerance of the carding box piece requires that we can only find it continuously after weaving for a certain length of time, which requires dismantling and re-braiding. To overcome the above drawbacks, max spajeck gmbh uses a quad (surface or v-shaped) tuoeah for box sections with shadows at the bottom or only quads. Thanks to the elasticity of the corner pins, the warp can be corrected regardless of thickness tolerances.
A fair identification. Figure 6-~ is a concave shaded box, Figure (a), Figure (b) is an arc section, Figure (e), Figure (d) is a v-shaped section. As shown in Figure (d), h is greater than the thickness of the piece, so there is room to use its flexibility to adjust the box gap.
The box of the carding machine also has the following advantages: (1) If the crown is cut into four shapes, the white sheet can effectively control the thickness and the actual design thickness of the large company. When using a large tolerance pin, it can reduce material consumption. and weight. (2) The elastic deformation of the pin pieces of the carding machine makes the arrangement between the fan pieces and the box pieces close, which improves the rigidity of the whole box and can effectively prevent the weft pieces from breaking. (3) If the use of medium density, double latitude, and tetraploid bacteria is also Suli, as long as the size of the elasticity needs to be controlled in chess, the goal can be achieved.
