(1) The length of the sliver trajectory data of each rotation of the coiling helical gear of the carding machine should generally be the product of the length of the sliver that can be sent out by the small pressure roller in the same period and the extension of the coiling sliver. 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.
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. (2) Conveying chute conduit gear, the gear box, will rotate through an appropriate angle when the gear on the chassis rotates with a radius equal to the diameter of the tampon, the arc length and the eccentricity of the circumference, so that only A tight circle is laid out.
(3) The forming of the sliver of the carding machine should be clear, not separated and adhered to each other, laid flat and not wrinkled, the air holes should be straight and run through the full height, and the size of the cylinder wall gap should be appropriate. (4) Under the conditions determined by the roll size (strip height and diameter), the maximum capacity of the strip should be provided to improve equipment utilization and labor productivity. (5) The carding machine coiler can adapt to high speed, light load, low noise, low wear, low power and easy maintenance.
Due to the limited height of the strip, the method to increase the capacity of the strip is to increase its diameter and design relevant parameters reasonably. The sliver is laid in the coil plate through the coil plate, and becomes a cylinder with air holes in the center. The total weight of the sliver can be calculated according to the following formula: In actual production, the density of the sliver in the sliver can vary greatly.
The inner density of the ring with the width of the sliver diameter around the air hole can be the largest, followed by the edge of the sliver, and the density of other different parts is the smallest. The higher the density "extreme", the smaller the can capacity. One of the developmental problems of reducing the "extremely poor" network density is a reasonable and effective solution to the relationship between can diameter (D), pore diameter (do), eccentricity (e) and sliver diameter (d). .
If the large circle bar meets one of the following two formulas, the bar has the largest market capacity. According to the teaching design of the above formula, it is expected that the maximum environmental capacity of the can cannot be obtained through the diameter of the air hole. There is a reciprocating working device of the chassis used in foreign countries, so that the strip has economical rotation and continuous reciprocating motion in the front and rear, so that the obvious difference in the density of the storage in the strip is gradually reduced, and the measured capacity can be increased by more than 15%.
The sliver speed ratio is related to the sliver capacity and the quality management of the sliver in the can. When the coiling speed ratio is large, the sliver capacity is increased, but it cannot be significantly increased. If the coiling speed ratio is selected in an appropriate way, it will not only not affect the system capacity too much, but also improve the quality of sliver storage and reduce sliver hair, adhesion and other problems.
