The friction disc let-off mechanism of the carding machine does not use a brake, and people can swing freely during the entire spinning time of the main drive. 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). 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.
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. It adopts the rear inertia of the large back beam to facilitate the production with large beating-up tension. For example, a box-shaped hat loom of about 2 meters, after weight up to 50 kilograms.
It works as follows: when beating up, the opening of the loom moves forward; as a result of this, the warp remains in a state of friction between the morning delivery and the man's support later; man's bags and commerce tend to slip after the warp arrives, The latter does not turn in the holder, and the warp length from morning to opening increases rapidly with tension (Figs. 10-14). At this time, the underlying warp capacity ti did not increase in time, that is, due to the frictional resistance of the backspread, the change in flight was captured behind the tzo t, and the rapid increase in the torque t mountain a increased, causing the consequences of the activity , while the pivot point a is rotated clockwise, the consequences will be snapped to the original equilibrium position. Until t, increase to overcome the resistance of the meiming, after the warp is dragged, it slides along the surface of the rear person, ti gradually becomes thinner, and finally makes the movement of the rear beam the child calls tend to balance, after that.
Stop making fun of me. After beating, the opening moves backwards, the warp tension drops first, and the back beam moves along the hem. after.
The greater the inertia, the smaller the bait. To avoid this advantage being passed on to the adjustment device, sequence 5 and sequence 7 in Fig. 10-4 are not connected by a chain, but are used to adjust the position of the two bolts shown in the figure, which can be determined by the oscillation of the dynamic warp tension by the two The gap control between the screws does not emit an x number. Only when the amount of let-off is insufficient or too large, the average tension of the warp yarn will change, and the pin 6 pushes the upper screw and the lower screw, so that the adjustment device enters the workpiece.
