[0034] Working principle: During use, the staff sets the cotton web on the air shaft 11 for cotton loading processing. When the thickness of the cotton web on the surface of the air shaft 11 is less than the detection range of the induction photoelectric eye 208, the alarm 3 issues an alarm to prompt the staff to change the cotton. During cotton changing, the staff uses an external control switch to start the electric push rod 5 and the first motor 7. The output end of the electric push rod 5 drives the L-shaped plate 6 and the first motor 7 to move. At the same time, the output end of the first motor 7 drives the first synchronous pulley 8 to rotate. When the first synchronous pulley 8 rotates, it drives the belt 9 to transmit power. When the telescopic end of the electric push rod 5 drives the first motor 7 to move to a specified position, the inner side of the belt 9 contacts the surface of the second synchronous pulley 12, and then the second synchronous pulley 12 can be driven to rotate. When the second synchronous pulley 12 rotates, it drives the air shaft 11 to rotate, and the remaining cotton web can be quickly wound up, thus improving the cotton changing efficiency of the staff. And the output end of the second motor 202 drives the gear 203 to rotate, which can make the toothed plate 204 drive the L-shaped bracket 205 to move, so as to adjust the position of the induction photoelectric eye 208. By adjusting the position of the induction photoelectric eye 208, it is convenient for different staff to use, enabling the staff to have sufficient time for other production of the cotton web.
