(1) The phenomenon partially or completely surrounds a small volume of paper feed roller sliver or lower roller cotton, cotton roller, thus causing film, one side wool or not all output hanging, making children's car thin noodles or even broken strips. 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. 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). (2) Reason analysis 1. There are burrs on the surface of the upper and lower feeding rollers, or after the surface is stained with oil or sticky with warm hands, it is easy to remove fibers during the winding process. 2. The temperature and humidity of the workshop are not suitable.
If the temperature is too high, it is easy to dissolve the cotton wax in the cotton fiber, wither on the surface of the Laura, and the adhered fibers are entangled, and the relative humidity is too high, which is also an important factor for entanglement. (3) Repair method 1. After installing the upper and lower cloth feeding rollers or stripping the ginning fiber, wipe the surface of the cloth feeding roller with a dry and clean rewinding or rag. If it is summer, sweat should be wiped off.
2. The grooved roller is fitted with cotton wax and dirt sticks, the roller should be removed with a hot water or gasoline swab to remove the shovel. 3. Rollers can be used in places with burrs on the surface“00”No. of fine sandpaper (or by using old“0”No. sandpaper) and smooth it. 4. If the temperature and humidity control in the processing workshop of the carding machine is improper, the comrades who manage the temperature and temperature should be strengthened to adjust the temperature and humidity of the enterprise workshop to keep within a normal working range (generally, the design temperature of the workshop should be controlled at 22 ~28°C, it is more appropriate to control the relative humidity at 55~65%).
(4) Preventive measures During installation and operation, the management thinking should be centralized, the system operation sequence should be implemented, the students' operation tour should be strengthened, effective prevention should be the main focus, and unnecessary damage to the enterprise should be discovered and reduced in time. (5) Suggestions for improvement When it is necessary to speed up or re-quantify and feed, rearrange the pins. 1. In order to improve the strength and combing effect of cylindrical needles in the last 4 rows (14-17 rows) of 31~3s fine needles, 26 flat needles/cm were planted.
2. Syringe needle 33 instead of needle 28, needle 28 is more prone to damage than needle 33 in the long run, the final performance can improve carding. After setting the above two measures to rearrange the sliders of table 1-20, a table more suitable for B-type machine is designed. 3. Some factories are conducting experimental research on the use of fine sawtooth Xinjinlong to improve the carding efficiency of students.
