[0021] When winding the cotton quilt, the power supply of the motor 1 is turned on, the power output shaft of the motor 1 rotates to transmit power to the main machine 2, the main machine 2 drives the winding shaft 3 to wind the cotton quilt, at the same time, the power output shaft of the motor 1 transmits power to the rotating part 501 of the screw assembly 5, the rotating part 501 rotates and drives the translation part 502 to move linearly, when the translation part 502 contacts the first button 401 of the first trigger mechanism 4 and presses the first button 401, the first trigger mechanism 4 sends a power-off signal, the controller cuts off the power supply of the motor 1, the motor 1 stops rotating, and then the winding shaft 3 stops winding the cotton quilt; by setting the distance between the translation part 502 and the first trigger mechanism 4, the winding termination position of the cotton quilt on the greenhouse can be controlled, manual visual judgment is not needed, the accuracy of the cotton quilt winding position is improved, the cotton quilt is prevented from being wound excessively, the safety of the cotton quilt winding work is improved, the manual labor during the re-expansion of the cotton quilt is avoided, the manual resources are saved, and the work efficiency of the cotton quilt winding is improved.

[0022] Further, the rotating part 501 is connected with the power output shaft of the motor 1 through the speed reduction gear set 6. The rotating part 501 is reduced in rotation number in proportion to the rotation number of the power output shaft of the motor 1 by the speed reduction gear set 6. For example, when the cotton quilt is rolled up from the bottom of the greenhouse, the rotation number of the power output shaft of the motor 1 is 60, and the rotation number of the rotating part 501 driven by the speed reduction gear set 6 is 10.
