The carding machine is mainly composed of cotton rollers, cotton sheets, rods, dust removal knives, etc. 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). 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. Its structure is shown in the figure. 3-1. The main function of this part of the mechanism is to comb the cotton layer with the roller.
The cotton layer is fed with a cotton roller, and the cotton layer is combed with a licker-in roller. The fiber on the licker-in is supported by the dust-removing knife and the small leakage bottom, and the impurities are removed under the combined action of the licker-in, the dust-removing knife and the small leakage bottom. Card feed and licker-in section Card feed roller mechanism The outlet of the card licker-in plate forms a strong jaw that is clamped and restrained on the cotton layer of the licker-in , giving a strong open card to the entire lateral width of the cotton layer.
If the rollers are weak against the batt, the carding effect of the licker-in to grab the tuft from the batt will be great and poor. For example, in the lateral width of the cotton layer, due to the strong clamping force in the area where the thickness of the cotton layer is uneven, the clamping force of the thin layer is weak. This uneven clamping will affect the uniformity of the cotton layer by the carding machine. Therefore, the cotton roller requires uniform clamping force and lateral clamping force on the cotton layer.
Feed rollers as well as bearings with inner baffles for bearings. As shown in Figure 3-2. The two ends of the feeding roller car are respectively installed in a feeding roller bearing with a width of 60 mm. The feeding plate is equipped with a bearing with an inclination of 15 to the vertical line, and a baffle is used. When the thickness of the feeding layer changes, the feeding The roller can slide up, down, left and right along the different baffle slope designs along with the bearing.
Since the feeding roller thorn and the feeding plate have the effect of friction on the grip of the cotton layer, the surface of the output roller has a tooth-shaped uniform groove, and the financial lever is used at both ends of the enterprise to be pressurized by a spring system. Appropriate development and aggravating social pressure can not only increase the gripping force of the feeding roller on the cotton layer, but also reduce the large difference in the pressure of the feeding roller on the thickness of the cotton layer, and improve the uneven lateral grip of the cotton layer. There is a certain tension control indication time scale on the pressurized air spring box of the feeding roller on the A186 type carding machine. When the indication scale is at the spoon position, the actual pressure of the cotton layer is 370 kg, and at 2:00, it is 412 kg. Going one step further, the total working pressure at both ends is increased by 42 kg, so that you can flexibly and effectively adjust the financial pressure you need.
