Carding machine licker-in speed

Experiments show that when the mechanical state and output of the carding machine are constant, the percentage of cotton bundles decreases with the increase of the drum speed, but decreases when the drum speed exceeds a certain range. 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.

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). When the mechanical state and roll speed are constant, the percentage of cotton tuft increases with the increase of production. The reason for this change is the change in the number of teeth of the rollers on the fibers.

Therefore, when the output of the carding machine increases, the speed of the drum must be increased accordingly to ensure the carding effect. The general output range and twist speed of the carding machine are shown in Table 4-10. It should be noted that the overspeed licker-in does not significantly improve the carding effect, but will increase fiber damage, such as power consumption and maintenance work. Cotton carding rollers to clamp cotton and cotton and hold whiskers between plates not only solid, but also have a uniform lateral grip, grab or sawtooth bundle fibers, and the carding effect affects the licker-in.

Heavy pressure is generally used to increase the clamping force of the cotton layer when the quantitative yield of the collar is increased or heavy. Appropriately, when the pressure is increased, not only the holding force can be increased, but also the uneven lateral grip, but the excessive pressure to bend the center roll batt upwards to weaken the grip of the holding force of the center roll batt layer , but makes the lateral grip unevenly increased. Therefore, in the new card, the diameter of the weight feed roller is increased after the pressure of bending deformation is used, and the reduced roller method is used for enhanced stiffness.
