(Summary description)1.2 Overview of the process equipment flow 1. Into the cotton The raw staple fiber is manually placed on the long curtain in proportion, and the long curtain is conveyed to the entrance of the mixer. 2. Cotton blending 2-1 Use photoelectric control to control the feeding amount of cotton fed by the cotton feeder; 2-2 Use photoelectricity to control the amount of cotton stored in the blender and quantify the thickness or weight before sending it to the opening machine entrance. 3. Opening 3-1 The feeding part is controlled by the photoelectric control of the cotton feeder. 3-2 The opened raw material (short fiber) is sent to the cotton feeder through the material pipeline by a fan. 4. For cotton 4-1, use a photoelectric switch to control the raw material fed from the opener. 4-2 Use the photoelectric meter on the diagonal nail curtain to control the raw material sent to the entrance of the carding machine.入量. 5. Pre-carding 5-1 Use the frequency conversion to control the input amount thickness or weight  5-2 Method: Manually fine-tune the speed of the frequency converter and send it to the netting machine. 6. Laying machine The raw material that enters the laminating machine is fed into the main carding machine by cross-folding more than 5 layers of staple fibers that have been laid out in the horizontal and vertical directions. 7. Main carding 7-1 Frequency conversion control of the flake staple fiber sent from the web-laying machine. 7-2 The raw material the staple fiber is split through the cylinder, work roll and stripping roller. 7-3 The doffer The raw material short fiber is transferred to the messy roll. 7-4 The messy roll disrupts the fiber to increase the transverse strength. 7-5 The stripping roll strips the forming web from the messy roll and sends it to the web conveying curtain. Three-layer composite   7-6 The edge trimmed by the trimming machine enters the hot rolling. The trimmed trim is sent to the cotton feeder through the air duct. 8. Hot rolling The sheet material short fiber that enters the upper and lower hot rolls of the hot rolling mill from the main combing machine is subjected to hot press forming by adjusting the temperature and pressure of the hot roll to adjust the temperature and pressure required by the process. *The temperature of the hot roller, the hot oil 235240℃, is sent to the upper and lower hot rollers by the hot oil pump from the heating oil furnace. *Heat roller pressure: compressed air provided by the air compressor passes through the pressure regulating device, the upper pressure is 1.2MPa, the lower pressure is 0.80.9MPa, and enters the pressure regulating cylinder. 9. The product from the hot rolling mill is rolled after trimming. Long rolls are wound into rolls. The maximum diameter of rolls is 800mm. 10. Finished product inspection and weighing 10-1 Sampling and testing its physical indicators according to product quality standards (10-2) Weigh each roll of product. 11. Rewinding If there is a requirement for the number of broken ends of the product from the winding machine during the winding process, rewind and mark the broken ends. 12. Packaging, warehousing, leaving the factory 12-1 Different products are packaged and labeled, 12-2 the packaged products are put into the warehouse, and 12-3 are sold and left.
