The working principle is to open, comb and remove impurities from the cotton rolls sent from the previous process or the oily cotton layer supplied by the cotton box, so that all the curled cotton loops become basically straight single fibers. In the process, the broken seeds, impurities and short fibers left over from the cotton cleaning process are removed, and then cotton strips of a certain specification are integrated and stored in cotton tubes for use in the drawing process.

[0036] See also Figure 5 Limiting grooves 24 are provided on both sides of the lead frame 3, and the width of the limiting grooves 24 is the same as the width of the turning handle 23. The turning handle 23 can be pulled and turned to enter the limiting grooves 24, which facilitates the staff to complete the installation or removal of the cover plate 17.

[0037] Working principle: first, when it is necessary to parallel the cotton strips, multiple groups of cotton strips are passed through the gap between the adjusting roller 5 and the electric roller 4, and the height of the adjusting roller 5 is adjusted by rotating the bolts on both sides of the adjusting roller 5 so that the adjusting roller 5 fits the cotton strips, and then the multiple groups of cotton strips are pulled to pass through the lead frame 3, and the multiple groups of cotton strips are paralleled through the lead frame 3. The paralleled cotton strips will be discharged through the circular outlet of the lead frame 3, and then the paralleled cotton strips are pulled through the gap between the cleaning plate 9 and the curved surface block 10, and then the bidirectional threaded rod 11 is rotated. Since the bidirectional threaded rod 11 is threadedly connected to the threaded block 8, and the threaded block 8 is slidably connected to the sliding frame 7, the rotation of the bidirectional threaded rod 11 will drive the threaded block 8 to move in the sliding frame 7, and the movement of the threaded block 8 will drive the cleaning plate 9 to move. The movement of the cleaning plate 9 makes the brush on one side fit the outer side of the cotton strip and push the cotton strip to fit one side of the curved surface block 10;

[0038] Secondly, pull the cotton strip through the wire tube 16 and wind it around the take-up roller 2, then start the motor at the bottom of the electric roller 4 and the take-up roller 2, the motor at the bottom of the take-up roller 2 will drive the take-up roller 2 to rotate, and the motor 4 will drive the cotton strip to move, and the take-up roller 2 and the electric roller 4 will cooperate with each other to wind the parallel cotton strip around the take-up roller 2, and the cotton strip will pass through the gap between the cleaning plate 9 and the curved block 10 during the conveying process, and the cotton strip will be cleaned by the brush of the cleaning plate 9 once, and the cotton strip will fall into the collection frame 12 under the influence of gravity, and the subsequent staff can recycle the cotton strip in the collection frame 12 by opening the sealing door 13;

[0039] Finally, when it is necessary to maintain the internal structure of the lead frame 3, the handle 23 is manually pulled. The movement of the handle 23 will drive the sliding rod 20 to move, and the movement of the sliding rod 20 will drive the fixed block 21 to move. The movement of the fixed block 21 will separate from the fixing groove of the docking block 18, and the movement of the fixed block 21 will cause the spring 22 to deform. When the handle 23 is pulled to the position of the limit groove 24, the handle 23 is rotated so that one end of it is embedded in the limit groove 24, and the handle 23 is temporarily fixed through the limit groove 24. Then, the cover 17 can be pulled to complete the disassembly. When the internal structure of the lead frame 3 is maintained, the docking block 18 at the bottom of the cover 17 is inserted into the fixed frame 19, and then the handle 23 is rotated again to separate it from the limit groove 24. At this time, the spring 22 will restore the deformation and push the fixed block 21 to move, and the fixed block 21 will move into the fixing groove of the docking block 18, thereby completing the fixation of the cover 17. The operation is simple, which is convenient for the staff to regularly maintain the component.
