Figure 3-1 shows the schematic diagram of the A186 carding 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. 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. 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 lap 2 is embedded in the groove of the lap holder 1, and the lap 3 is thereby fixed on the lap roller 4. With the rotation of the lap roller, the lap is slowly degraded layer by layer by means of trade friction. Under the grip of the feeder plate 5 and the feeder roller 6, the cotton layer is conveyed forward by the rotation of the feeder roller, and is opened and combed by the rotating licker-in roller 7 at an economical high speed.
The pile roll 8 prevents the presence of overflow of the fibers on the licker-in. Below the licker-in is a dust-removing knife 9 and a small drain bottom 10, which supports the long fibers caught by the licker-in teeth, and cooperates with the licker-in to remove other impurities and stab short fibers. The teeth of the licker-in or the fibers grabbed meet the Xinjinlong 11 after passing through the dust removal knife and the small leakage bottom.
The surface of Xinjinlong is covered with metal card clothing, and its surface treatment speed is significantly higher than that of the licker-in. The needle teeth strip the fibers on the surface of the licker-in, and enter the Xinjinlong, cover and work area through the rear cover 12. The surface of the cover plate 13 is covered with elastic card clothing. There are 106 pieces in the whole machine, and one of them is 40 pieces in the state of social work and life. The influence of the surface reaction speed of Xinjinlong is far greater than that of the cover plate, and the fibers are carded into a single-cell fiber tissue state under the important action of the two needle surfaces, and the purpose of removing impurities from these small products is achieved by fully mixing materials.
The fiber thorns on the needle surface of the cover plate are filled with impurities, which are peeled off by the upper chopper 14 and become the movable cover plate flower after walking out of the working area. The stripped cover can be re-entered into the corporate work area from above the licker-in at the rear of the machine. The fibers caught by the Xinjinlong needle teeth meet the doffer 18 through the front upper cover plate 15, the needle copy door 16, and the front lower cover plate 17.
Doffer believes that the surface is also covered with metal card clothing, and its surface speed in China is much lower than that of Xinjinlong. Under the educational effect of the two needle surfaces, some of the research fibers on Xinjinlong have condensed to the doffer needle surface, forming a thin green color. fiber layer. Most of the fibers left on the surface of Xinjinlong will be re-selected into the working area of Xinjinlong and cover plate protection through the large drain bottom 19 and the fibers stripped from the licker-in, mixed with each other and accepted by us for re-carding. The fiber layer condensed on the surface of the doffer is peeled off by the stripping roller 21, and a small amount of short fiber thorn impurities left on the surface of the doffer are discharged out of the machine by the intelligent dust hood 20.
The fiber layer on the stripping roller is transferred to the output roller 22 and stripped off by the upper and lower nip rollers 23 to become a cotton web. The cotton web is combined into a cotton sliver through the large pressure roller 25 at the la team mouth 24. The coiler 26 regularly coils the sliver into the tampon holder 27.
The main information technology environmental characteristics of the A186 type card are listed in sub-table 3-1.. The functions and the location of the main mechanisms, including them in the licker-in section, the cylinder, the doffer section, and the ejector pin As part of the thorn state, its structure and effects are analyzed in detail later in three parts.
