[0002] The film, also known as thin film plastic, is mainly composed of polyethylene. It is mainly used to cover farmland. It plays a role in increasing ground temperature, maintaining soil moisture, promoting seed germination and rapid growth of seedlings, and inhibiting the growth of weeds. The seedlings need to be ventilated and cooled when they grow, so a punching device is needed to punch holes in the agricultural film.

[0003] Now, a punching machine is used when punching holes in agricultural film. However, the existing punching machine needs to manually position the agricultural film during the process of punching holes in the agricultural film, that is, the operator needs to clamp and position the agricultural film before punching holes. After the punching is completed, the agricultural film is loosened and holes are punched in other positions of the agricultural film. It is cumbersome and time-consuming to use, which is not conducive to the overall processing speed.

[0004] To this end, we propose an agricultural film punching device for agricultural film processing. Utility Model Content

[0012] Beneficial Effects

[0013] The utility model provides an agricultural film punching device for agricultural film processing, which has the following beneficial effects:

[0014] (1) When the agricultural film punching device is used for agricultural film processing, one end of the agricultural film is set on the winding mechanism so that the agricultural film can be wound up. In addition, when punching holes, the cam plate is rotated by the rotating mechanism, and the end of the cam plate away from the axis contacts the movable frame, squeezing the movable frame to move downward. The first spring will be compressed. During the descent of the movable frame, the positioning plate will first contact the agricultural film. The positioning plate is forced to move upward with the connecting slide rod. The second spring begins to stretch and generates elastic force. The elastic force will act on the agricultural film to squeeze and position the agricultural film. At the same time, the punching column will follow the movable frame to move downward to punch holes in the agricultural film. Manual clamping and positioning are not required, which is convenient to operate and improves processing efficiency.

[0015] (2) When the agricultural film punching device is used for agricultural film processing, the agricultural film is sent through the position between the limiting roller and the punching device body, and then wrapped around the outer wall of the winding wheel. The limiting roller can limit the agricultural film. By turning on the stepper motor, the stepper motor drives the connecting rotating rod to rotate, and the transmission belt drives the transmission rotating rod to rotate. When the transmission tooth plate and the transmission gear are in meshing process, the movable rotating rod drives the winding wheel to roll up the agricultural film. When the transmission rotating rod and the transmission gear are in a non-meshing process, the cam plate will rotate and squeeze the movable frame to complete the punching operation. The transmission tooth plate with different numbers of tooth plates can be replaced, and the movement distance of the agricultural film each time can be changed, thereby realizing the change of the interval size of the punching, thereby improving practicality.
