After the carding machine realizes the large package, in order to facilitate the workers to operate at the back of the machine, the carding machine must use the overhead input (see Figure 5-1). 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. 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 feeding mechanism of the carding machine consists of guide rollers, traverse devices, etc. The driver diagram is shown in Figure 5-2. The front, middle and rear guide pulleys are actively driven by the rear guide pulley through the chain and sprocket, reducing accidental drafting.
Here, the height of the guide rollers from the ground, the position of each other, the distance between the front guide rollers and the speed of each guide roller, etc. Easy to operate and reduce accidental drafting. When the sliver strength is low (such as combed sliver), the following methods can be used: (1) Increase the pressure on the card to stop the pressure.
(2) Reduce the transmission ratio of the rear roller to the guide roller. (3) Reduce the height of the guide rollers and reduce the distance between the guide rollers. In the traverse device at the rear end of the worm-driven rear roller, due to the planetary structure, the movement is slow and stable.
When the bell mouth and the traverse guide slowly reciprocate the rubber roller and the roller, which prevents the movement of the sliver between the grooves of the glue series ground, stop acting as a protective colloid. The bell mouth is installed on the lateral guide rod, and the size of the opening should be adapted to the feeding bar.
