[0020] As Figure 1 and Figure 2 shown, a specific embodiment of the present utility model provides a labor-saving film winder, which is used for the film winding operation of a greenhouse, and has the characteristics of labor-saving operation and convenient use; specifically, it includes a body 100 and a reduction gear set arranged in the body 100; an input gear disc 200 located outside the body 100 is drivingly connected to the input end of the reduction gear set, and a control zipper 300 for pulling the input gear disc 200 to rotate is arranged on the input gear disc 200; the output end of the reduction gear set is drivingly connected to a film winding rotating shaft 400 that penetrates out of one side of the body 100 away from the input gear disc 200; the reduction gear set is also drivingly connected to a ratchet wheel, and a pawl cooperating with the ratchet wheel is arranged in the body 100.
[0021] As Figure 1 and Figure 2 shown, through the above settings, the film winder in this embodiment can be arranged in the film winding area at the upper end of the greenhouse during use. Before operation, the end of the greenhouse film needs to be connected to the film winding rotating shaft 400 through a connecting rope. After the body 100 is fixed, the film winding operation can be carried out. The user pulls the control zipper 300 to drive the reduction gear set to rotate through the input gear disc 200. The reduction gear set reduces the rotation speed of the film winding rotating shaft 400 after deceleration, making it more labor-saving to pull the control zipper 300 and more convenient for single-person operation. In practical applications, the reduction ratio of the reduction gear set is selected according to needs. In this embodiment, the tooth speed ratio is 12:1, which improves the convenience of operation while saving labor; this embodiment also uses a ratchet structure to control the rotation direction of the reduction gear set, and the set ratchet structure can prevent the film from rebounding during the upward curling process; when the film needs to be released, by releasing the pawl, the film winding rotating shaft 400 can rotate in the reverse direction, improving the safety of operation.
