The multiple sets of take-up rollers 10 are driven to rotate synchronously by the drive mechanism installed on the side wall of the frame 1. The take-up roller 10 is detachably connected to the drive mechanism. The drive mechanism is composed of a motor-driven chain transmission assembly. It should be noted that the unwind roller 2, the first guide roller 4 and the second guide roller 9 are respectively driven to rotate by corresponding motors installed on the side wall of the frame 1.

[0020] Furthermore, the adjustment mechanism includes: a mounting base 5, a fixed base 6, an adjustment base 601, and a telescopic frame; the mounting base 5 is mounted on the frame 1; the fixed base 6 is mounted in the middle of the mounting base 5; multiple sets of adjustment bases 601 are provided, and the multiple sets of adjustment bases 601 are symmetrically distributed on both sides of the fixed base 6. The adjustment bases 601 are slidably connected along the width direction of the mounting base 5. A connecting base 603 is installed on one set of adjustment bases 601 at the end. The connecting base 603 is connected to the side wall of the mounting base 5 through a telescopic component. The telescopic component is a hydraulic rod. The cutting blade is installed at the bottom of the adjustment base 601 or the fixed base 6. The cutting blade consists of a blade holder 8 and a blade 801 installed at the bottom of the blade holder 8. The blade holder 8 is connected to the bottom of the fixed base 6 or the adjustment base 601 by bolts; the telescopic frame is installed between the fixed base 6 and the multiple sets of adjustment bases 601.

[0021] Furthermore, the telescopic frame includes: a first shaft 7, a first connecting rod 701, a second connecting rod 702, and a second shaft 703; multiple sets of first shafts 7 are provided, and the multiple sets of first shafts 7 are respectively installed on the fixed seat 6 and multiple sets of adjusting seats 601; four sets of first connecting rods 701 are provided, and the first connecting rods 701 are rotatably connected to the corresponding first shafts 7. Two sets of first connecting rods 701 are rotatably connected to the two sets of adjusting seats 601 located at both ends of the telescopic frame, and the two sets of first connecting rods 701 are V-shaped; multiple sets of second connecting rods 702 are provided, and every two sets of second connecting rods 702 are connected to the fixed seat 6. The first shaft 7 is rotatably connected, and the two sets of second connecting rods 702 are in an X-shape. Multiple sets of second shafts 703 are provided. The end of the first connecting rod 701 away from the corresponding first shaft 7 is rotatably connected to the end of the adjacent second connecting rod 702. The end of the second connecting rod 702 away from the corresponding first shaft 7 is rotatably connected to the end of the other adjacent sets of second connecting rods 702. It should be noted that a displacement sensor is provided between the two sets of adjusting seats 601 to detect the distance between the two sets of cutting blades and improve the adjustment efficiency.

[0022] Furthermore, the mounting base 5 has a guide rail 501 on its side wall, and the fixed base 6 is installed in the middle of the guide rail 501 by bolts. The adjusting base 601 is equipped with a slide 602, which is slidably connected to the guide rail 501. The guide rail 501 is U-shaped, and the slide 602 is L-shaped.

[0023] Furthermore, two sets of U-shaped frames 301 are installed inside the frame 1. The tensioning roller 3 is rotatably connected to the corresponding U-shaped frame 301. Multiple sets of elastic elements 302 are installed between the U-shaped frame 301 and the bottom end of the frame 1. Each elastic element 302 consists of a telescopic rod and a spring sleeved on its outside. The telescopic rod guides the spring, allowing it to extend and retract only along the height direction of the telescopic rod. The spring enables the tensioning roller 3 on the U-shaped frame 301 to self-adjust, thereby adjusting the tension of the biodegradable membrane and preventing the biodegradable membrane from being too tight or too loose.

[0024] In this embodiment, since the fixed seat 6 is fixedly installed on the guide rail 501, and the adjusting seat 601 is slidably connected to the guide rail 501, when the telescopic component is activated by the controller to drive the connecting seat 603 to move horizontally along the mounting seat 5, multiple sets of first connecting rods 701 and second connecting rods 702 rotate and adjust along the corresponding first shaft 7 and second shaft 703. This causes the telescopic frame to retract or expand around the fixed seat 6, thereby driving multiple sets of cutting blades to adjust their spacing equally. According to the needs of using the biodegradable membrane, the spacing between the multiple sets of cutting blades is adjusted to a suitable distance. Then, multiple sets of winding drums with the same width are respectively installed on the corresponding winding rollers 10. The drums with the biodegradable membrane are installed on the unwinding rollers 2. The ends of the biodegradable membrane are passed through the tension rollers 3 and two sets of... The first guide roller 4 cuts the biodegradable film with multiple sets of film-cutting blades. The cut biodegradable film is then passed through another set of tension rollers 3 and the second guide roller 9, and then wound onto the corresponding take-up roller 10. The multiple take-up rollers 10 can then be started to rotate, and the unwinding roller 2 can be started to unwind the film. The biodegradable film is continuously cut by multiple sets of film-cutting blades, dividing it into multiple sets of equal width. The spacing between each set of film-cutting blades can be adjusted by the adjustment mechanism, thereby cutting biodegradable films of different widths. It should be noted that a cutting blade, as described in the patent with authorization announcement number CN222450543U, is installed on the frame 1 between the second guide roller 9 and the multiple sets of take-up rollers 10. This blade can cut the biodegradable film after it has been wound onto the take-up roller 10 for a certain length, making it easier to collect the material.

[0026] like Figures 1 to 3 As shown, the biodegradable membrane cutting machine proposed in this utility model, compared with Embodiment 1, has a U-shaped mounting base 5 with two sets of ear seats 604 symmetrically mounted on the mounting base 5. The ear seats 604 are mounted on the frame 1 through a lifting component. The frame 1 has a clearance opening corresponding to the ear seats 604. The lifting component is a hydraulic rod, and the ear seats 604 are adjusted along the height direction of the frame 1 by the hydraulic rod.

[0027] In this embodiment, the controller starts the synchronous movement of two sets of lifting components. The lifting components drive the ear seat 604 to move and adjust the mounting seat 5 along the height direction of the frame 1, thereby driving multiple sets of film cutting blades to adjust upward or downward. When the biodegradable film passes through the two sets of first guide rollers 4, the mounting seat 5 can be adjusted up and down to facilitate the adjustment of the position of the die-cutting blade and the biodegradable film, which is convenient for film laying and cutting.
