[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1:

[0019] like Figure 1 and Figure 2 As shown, an agricultural film winding device includes a base 1. A first side plate 2 and a second side plate 3 are sequentially fixedly installed on one side of the upper surface of the base 1. Two rotating shafts 4 are rotatably connected through one side of the first side plate 2. The second side plate 3 is provided with a positioning mechanism that cooperates with the rotating shafts 4. The positioning mechanism includes a groove 6 formed on the outer surface of the second side plate 3. A rotating plate 7 rotatably connected to the groove 6 via a bearing is embedded inside the groove 6. A locking rod 8 is slidably connected through the outer surface of the rotating plate 7. One end of the rotating shaft 4 and one end of the locking rod 8 are both rectangular structures. Both ends of the winding roller 5 are provided with locking grooves 9 that cooperate with the rotating shaft 4 and the locking rod 8. A spring 10 is fixedly connected between one end of the locking rod 8 and the rotating plate 7.

[0020] In use, the take-up roller 5 is clamped between the rotating shaft 4 and the clamping rod 8. By pulling the clamping rod 8, and with the cooperation of the spring 10 and the groove 6, the take-up roller 5 can be easily installed and removed.

[0021] A motor 11 is fixedly installed on the outer surface of the first side plate 2 near the rotating shaft 4. The output shaft of the motor 11 and one end of the rotating shaft 4 are both fixedly connected to gears, and the two gears mesh with each other.

[0022] The rotation of motor 11 drives the rotating shaft 4 to rotate through two gears, which in turn drives the take-up roller 5 to rotate, thus winding up the film. Since there are two take-up rollers 5, after one take-up roller 5 has finished winding, the other take-up roller 5 can be used directly to wind up the film, which can improve work efficiency.

[0023] A winding roller 5 for winding agricultural film is provided between the rotating shaft 4 and the positioning mechanism. A tension detection and adjustment mechanism is installed on the upper surface of the base 1. The tension detection and adjustment mechanism includes an electric push rod 12 fixedly installed on the upper surface of the base 1. A connecting plate 13 is fixedly connected to the top of the electric push rod 12. A pressure sensor 14 is fixedly installed on the top of the connecting plate 13. A U-shaped frame 15 is fixedly connected to the top of the pressure sensor 14. A guide roller 16 is rotatably connected inside the U-shaped frame 15. A controller 17 that cooperates with the electric push rod 12 and the pressure sensor 14 is installed on one side of the upper surface of the base 1.

[0024] When the film is being wound up, the pressure sensor 14 can detect the tension of the film. When the tension changes significantly, the pressure sensor 14 can transmit a signal to the controller 17, which will then control the electric push rod 12 to operate and automatically adjust the tension, thereby improving the winding effect.

[0025] Two limiting plates 18 are symmetrically slidably connected to the outer surface of the take-up roller 5, and locking bolts 19 are threadedly connected to the outer surface of the limiting plates 18.

[0026] It can limit the movement of films of different widths.

[0027] Working principle: In use, the take-up roller 5 is clamped between the rotating shaft 4 and the clamping rod 8. By pulling the clamping rod 8, and with the cooperation of the spring 10 and the groove 6, the take-up roller 5 can be installed and removed. The motor 11 rotates, which drives the rotating shaft 4 to rotate through two gears, thereby driving the take-up roller 5 to rotate, so as to wind up the film. Since there are two take-up rollers 5, after one take-up roller 5 has finished winding, the other take-up roller 5 can be used directly to wind up, which can improve work efficiency.

[0028] When the film is being wound up, the pressure sensor 14 can detect the tension of the film. When the tension changes significantly, the pressure sensor 14 can transmit a signal to the controller 17, which will then control the electric push rod 12 to operate and automatically adjust the tension, thereby improving the winding effect.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description, and thus all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this utility model. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0030] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
