[0002] Agricultural film is a product used in agricultural production to protect plants from water loss. With the advancement of science and technology, the requirements for agricultural film are getting higher and higher, and various new types of film are constantly emerging. The production of agricultural film involves mechanically winding the film into rolls after it is formed, and then cutting it.

[0003] Chinese patent application CN202221827891.4 discloses a cutting device for plastic agricultural film production, relating to the field of plastic agricultural film technology. The device includes a base plate with a cutting groove at the center of its upper surface. Support plates are symmetrically fixedly connected to the upper surface of the cutting groove. Limiting grooves are symmetrically formed on the outer surface of the support plates. A top plate is fixedly connected to the upper surfaces of the two support plates. Reinforcing plates are symmetrically fixedly connected to the outer surfaces of the top plates. A first motor is fixedly connected to the upper surface of the reinforcing plates. The drive end of the first motor passes through the reinforcing plates and is fixedly connected to a first threaded rod. This invention, by starting the first motor, drives the first threaded rod to rotate, thereby causing the sliding frame to descend. That is, the lower surface of the pressing plate presses the plastic agricultural film against the base plate. Then, an electric telescopic rod is activated, causing the cutting frame to descend, thus cooperating with the cutting blade to perform the cutting operation. The device provides good cutting stability through its cooperation in pressing and cutting.

[0004] However, existing cutting devices still have some drawbacks, such as simple structure, inability to accurately cut plastic films to the required length, and low cutting efficiency. Utility Model Content

[0021] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. Identical components are indicated by the same reference numerals.

[0022] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0023] To make the content of this utility model easier to understand, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0024] like Figures 1 to 4 As shown, a cutting device for producing plastic agricultural film includes a worktable 1, a first fixing plate 2 installed at one end of the upper surface of the worktable 1, a winding mechanism 3 installed on the first fixing plate 2, guide wheels 4 installed in pairs on the upper surface of the worktable 1, a fixing frame 5 provided on one side of the guide wheels 4, a lifting mechanism 6 installed on the fixing frame 5, a second fixing plate 7 installed at the bottom of the lifting mechanism 6, an auxiliary mechanism 8 installed on the second fixing plate 7, and a length adjustment mechanism 9 installed on one side of the fixing frame 5.

[0025] The length adjustment mechanism 9 includes a mounting base 901 fixedly installed on one side of the worktable 1. A drive motor 902 is mounted on the mounting base 901. A threaded rod 903 is connected to the output end of the drive motor 902. An adjustment plate 904 is threadedly connected to the threaded rod 903. A guide rod 905 is installed on the other side of the worktable 1. The adjustment plate 904 is slidably connected to the guide rod 905.

[0026] Through the above scheme, the drive motor 902 drives the threaded rod 903 to rotate. The threaded rod 903 is connected to the adjusting plate 904 through a threaded pair, which converts the rotational motion into linear motion. The adjusting plate 904 slides along the guide rod 905, and its displacement is fed back to the control system through the encoder, so as to realize the precise setting of the cutting length. The precise length control reduces the waste generated due to cutting errors.

[0027] The lifting mechanism 6 includes an electric push rod 601 fixedly installed on the top of the fixed frame 5. The extended end of the electric push rod 601 is fixedly connected to the second fixed plate 7. An auxiliary rod 602 is sleeved on the fixed frame 5. The bottom end of the auxiliary rod 602 is fixedly connected to the second fixed plate 7. A cutting blade 603 is connected to the bottom end of the second fixed plate 7.

[0028] Through the above solution, the electric push rod 601 drives the cutting blade 603 to rise and fall vertically. With the guidance of the auxiliary rod 602, the cutting process is fast and stable, which greatly shortens the single cutting time and reduces the problem of uneven cutting surface caused by manual operation, thereby improving the overall production efficiency and quality.

[0029] The auxiliary mechanism 8 includes connecting seats 801 fixedly installed on both sides of the second fixed plate 7. An anti-slip frame 802 is fitted on the connecting seat 801. A return spring 803 is fitted on the anti-slip frame 802. A rectangular groove 804 is opened on the anti-slip frame 802. An anti-slip pad 805 is installed at the bottom of the anti-slip frame 802.

[0030] Through the above scheme, the reset spring 803 pushes the anti-slip frame 802 down, so that the anti-slip pad 805 is in close contact with the surface of the plastic agricultural film, effectively preventing the film from sliding or shifting during cutting. The design of the rectangular groove 804 further releases the stress during the cutting process, avoids the film from deforming due to excessive compression, and ensures cutting accuracy.

[0031] The unwinding mechanism 3 includes a second drive motor 301 fixedly installed at one end of the first fixed plate 2. The output end of the second drive motor 301 is connected to a rotating shaft 302. A baffle 303 is installed on the rotating shaft 302. A fixing nut 304 is threadedly connected to one end of the rotating shaft 302.

[0032] Through the above scheme, the drive motor 301 drives the rotating shaft 302 to rotate, and with the clamping structure of the baffle 303 and the fixing nut 304, the plastic agricultural film is automatically unwound and stably fixed, reducing manual intervention and labor intensity, while ensuring uniform film tension during unwinding and avoiding wrinkles or breakage.

[0033] The upper surface of the workbench 1 is provided with a cutting groove 101 that matches the cutting blade 603, and a scale 102 is provided on one side of the cutting groove 101.

[0034] Through the above scheme, the cutting groove 101 and the cutting blade 603 are precisely matched, ensuring that the blade is fully embedded in the groove during cutting, reducing burrs on the cutting edge. The introduction of the scale 102 makes it easier for operators to quickly locate the cutting starting point, further improving the controllability and repeatability of the cutting position.

[0035] The bottom of the workbench 1 is equipped with a support leg 10.

[0036] The working principle of this utility model patent is as follows: First, the plastic agricultural film roll is placed on the rotating shaft 302 of the unwinding mechanism 3, with baffles 303 limiting both ends and the fixing nuts 304 tightened to ensure that the film roll does not move axially. The second drive motor 301 is started, and the rotating shaft 302 rotates at a set speed. The film is guided to the cutting area by the guide wheel 4. According to the cutting requirements, the first drive motor 902 drives the threaded rod 903 to rotate, and the adjusting plate 904 moves linearly along the guide rod 905 until its end reaches the designated position of the scale 102. The electric push rod 601 is started. When the second fixed plate 7 descends, the anti-slip frame 802 is elastically pressed down by the return spring 803, so that the anti-slip pad 805 is in close contact with the film surface. The electric push rod 601 continues to push the second fixed plate 7 down, and the cutting blade 603 is embedded in the cutting groove 101 to complete the vertical cutting of the film. After the cutting is completed, the electric push rod 601 retracts, the second fixed plate 7 rises, the anti-slip frame 802 resets, and the film re-enters the waiting-to-cut state.

[0037] The above description is only a preferred embodiment of this utility model patent and is not intended to limit this utility model patent. Any modifications, equivalent substitutions and improvements made within the spirit and principles of this utility model patent should be included within the protection scope of this utility model patent.
