Cotton mixing: 1 Photoelectric control The cotton feeding amount of the cotton feeder is controlled by photoelectricity, and the cotton stored in the cotton mixing machine is quantitatively sent to the entrance of the opener.
Opening: the feeding amount is controlled by the photoelectric of the cotton feeder, and the opened staple fiber is sent to the cotton feeder by the fan through the material pipeline.
Cotton feeding: the photoelectric switch is used to control the cotton opener to feed raw staple fibers, and the photoelectric instrument on the inclined nail curtain is used to control the raw staple fibers to feed into the carding machine entrance.
Pre-carding: control the thickness or weight of incoming material through frequency conversion, manually fine-tune the speed of frequency converter and send it to the lapping machine.
Web laying: the raw materials entering the web laying machine are folded horizontally and vertically for more than 5 layers, and the laid sheet staple fibers are sent to the main carding machine.
Main carding: frequency conversion control is used to comb the flaky staple fiber sent by the winder. The original staple fiber is carded by the cylinder, the working roller and the stripping roller, and then transferred from the doffer to the messy roller, so that the fiber breaks and the transverse strength is increased. The paper stripping roller peels the formed paper web from the messy roller and sends it to the paper web conveying curtain for three-layer compounding. The scraps cut by the edge trimmer enter hot rolling and are sent to the cotton feeder through the air duct.
During hot rolling, sheet-like raw material short fibers entering the upper and lower hot rollers of the hot rolling mill from the main carding machine are hot-pressed to form the temperature and pressure required by the process by controlling and adjusting the temperature and pressure of the hot rollers. * The temperature of the hot roller is 235-240℃. The hot oil comes from the heating oil furnace and is sent to the upper and lower hot rollers by the hot oil pump. * The compressed air provided by the hot roller pressure air compressor enters the pressure regulating cylinder with a pressure of 1.2MPa and a pressure of 0.8-0.9MPa.
The product from the hot rolling mill is wound into a coil by an edge trimmer, and the maximum diameter of the coil is 800 mm
Inspect and weigh the finished products according to the product quality standards, sample and test their physical indicators, and weigh each roll of products.
