The A20lD split roller card has six linkages and a differential planetary gear train, shown in Figure 3-38. 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. 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. Constant speed drive roller on the power distribution shaft part separation (cylinder axis) eccentric cam 8 mm H when 11 is complete, the cam is the H-type planetary gear train of the tie rod, and rotates synchronously on the cylinder shaft; through the power transmission part is distributed 94T The large gear shaft is driven by the crank bolt drive gear 10 through the axle 2, crank gear 3 and 69T synchronously rotating the spool shaft gear 69T.

Total forward rotation and total reverse rotation The movement of the separation management mechanism is determined by the total forward rotation and total reverse rotation of the rollers separated by the enterprise, and the difference between the total length and the effective output of the total reverse clockwise rotation. The total amount of separation roll clockwise, and the total amount of the inverted several models are shown in Table 3-14.
When designing a new machine, shortening should minimize the effective length of the total output and reverse clockwise total output at the same time, thereby facilitating increased speed. As can be seen from the table, the fa261 card has the smallest total volume and total volume, followed by the fa251b, which is beneficial to the development of high-speed cards.
