Description

Technical Field

[0001] This utility model relates to the technical field of mulch film processing equipment, specifically a slitting machine for mulch film processing. Background Technology

[0002] Mulch film, also known as ground cover film, is usually transparent or black PE film, but also comes in green and silver. It is used to cover the ground to increase soil temperature, retain soil moisture, maintain soil structure, prevent pests from attacking crops and diseases caused by certain microorganisms, and promote plant growth. In agricultural production, different sizes of plots require different widths of mulch film. Therefore, slitting machines are needed to cut the finished mulch film during the mulch film production process.

[0003] In the prior art, patent CN217708254U discloses a slitting machine for film processing, including a worktable and a slitting unit; the worktable has a support plate on each of the left and right sides of the front and rear ends, a detachable feeding roller is rotatably connected between the inner sides of the two support plates at the rear left and right, and a detachable winding roller is rotatably connected between the inner sides of the two support plates at the front left and right, and a flattening unit is provided in the middle of the upper side of the worktable along the left and right direction;

[0004] Existing slitting machines for film processing have the following drawbacks: The slitting width is adjusted by manually moving a slider within a chute, which in turn moves the slitting blade. A spring is used to press and limit the slider, making it difficult to precisely adjust the slitting blade position due to manual slider movement. Furthermore, the spring-based slider-limiting mechanism is ineffective and may cause slider wobbling during use, resulting in inaccurate film slitting. Therefore, we propose a slitting machine for mulch film processing. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a slitting machine for processing mulch film. Through an adjustment mechanism, a specific gear rotates, which drives the corresponding screw to rotate, causing the slider at the corresponding position to move, which in turn drives the corresponding slitting blade to move. This allows for precise adjustment of the position of the slitting blade, thereby adjusting the slitting width. While precisely adjusting the slitting width of the mulch film, it also provides a better fixing effect on the slitting blade, effectively solving the problems in the background technology.

[0013] Furthermore, a pointer is fixedly connected to the upper right surface of the slider, and scale lines are provided on the upper surface of the mounting bracket to precisely adjust and control the movement position of the slitting blade.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0025] Please see Figure 1-6 This embodiment provides a technical solution: a slitting machine for processing mulch film, including a frame 1. A collecting roller 10 is rotatably connected to the left side of the inside of the frame 1, an unwinding roller 3 is rotatably connected to the right side of the inside of the frame 1, a guide roller 8 is rotatably connected to the inside of the frame 1, a mounting frame is fixedly connected to the left side of the inside of the frame 1, a protective shell 11 is fixedly connected to the front surface of the frame 1, a control switch 2 is fixedly connected to the right side of the front surface of the frame 1, the input end of the control switch 2 is electrically connected to an external power source, a motor 17 is fixedly connected to the left side of the rear surface of the frame 1, the front end of the output shaft of the motor 17 is fixedly connected to the rear end of the collecting roller 10, the input end of the motor 17 is electrically connected to the output end of the control switch 2, and a mounting base 4 is fixedly connected to the rear surface of the inside of the frame 1. The machine frame 1 is rotatably connected to a screw 5, and a knob is fixedly connected to the upper end of the screw 5. A slider 2 is threadedly connected to the outer surface of the screw 5. The rear surface of the slider 2 is slidably connected to the inner wall of the mounting base 4. A movable roller 7 is fixedly connected to the front surface of the slider 2. A fixed roller 6 is fixedly connected inside the frame 1. When it is necessary to cut the mulch film, the mulch film on the unwinding roller 3 with the mulch film is passed between the fixed roller 6 and the movable roller 7, then passed under the guide roller 8, and finally fixed to the outer surface of the collecting roller 10. Rotating the knob causes the screw 5 to rotate, which drives the slider 2 to move downward along the direction of the screw 5, and drives the movable roller 7 to move downward, so that the movable roller 7 and the fixed roller 6 provide pressure to the mulch film, keeping the mulch film in a taut state. The machine frame 1 also includes an adjustment mechanism 9.

[0026] Adjustment mechanism 9 includes screw 1 901, screw 2 902, screw 3 903, screw 4 904, driven gear 905, and drive gear 906. Screw 4 904 is rotatably connected to the front surface of frame 1. Screw 3 903 is rotatably connected inside screw 4 904. Screw 2 902 is rotatably connected inside screw 3 903. Screw 1 901 is rotatably connected inside screw 2 902. Driven gear 905 is fixedly connected to the left end of screw 1 901, screw 2 902, screw 3 903, and screw 4 904. Driven gears 906 are rotatably connected to the upper inner surface of protective shell 11. Driven gears 906 are all meshed with the laterally adjacent driven gears 905. Adjustment mechanism 9 also... The adjustment mechanism 9 includes a rotating rod 907, a first rotating cylinder 908, a second rotating cylinder 909, a movable rod 910, and a spring 911. The rotating rod 907 is rotatably connected to the front surface of the protective shell 11. A handle 12 is fixedly connected to the front end of the rotating rod 907. The first rotating cylinder 908 is slidably connected to the outer surface of the rotating rod 907. The second rotating cylinder 909 is fixedly connected to the rear end of the first rotating cylinder 908. The movable rod 910 is rotatably connected inside the second rotating cylinder 909. A spring 911 is fixedly connected between the lower surface of the movable rod 910 and the inner surface of the second rotating cylinder 909. The inner surface of the drive gear 906 is provided with slots. The movable rod 910 is fitted into the slots. The adjustment mechanism 9 also includes a rotating ring 912 and a locking rod 913. The rotating ring 912 is rotatably connected to the outer surface of the rotating rod 907. On the outer surface of the rotating ring 912, a locking rod 913 is fixedly connected. A limit groove is provided on the right surface of the protective shell 11. The locking rod 913 is slidably connected in the limit groove. When it is necessary to adjust the cutting width, the locking rod 913 is rotated upward, and then the locking rod 913 moves in the horizontal groove of the limit groove, driving the rotating cylinder 908 to move and the rotating cylinder 909 to move. The spring 911 pushes the upper end of the movable rod 910 upward, so that the upper end of the movable rod 910 is in close contact with the inner arc surface of the drive gear 906 that needs to be adjusted. After moving to the specific position, the locking rod 913 is rotated downward, so that the locking rod 913 is fixed in the vertical groove of the limit groove. At this time, the handle 12 is rotated, and the rotation of the handle 12 drives the rotating rod 907 to rotate. The rotating drum 908 rotates, which in turn rotates the rotating drum 909, causing the locking rod 913 to rotate. When the locking rod 913 rotates to the position corresponding to the locking slot, the locking rod 913 engages in the locking slot. Then, the handle 12 continues to rotate, causing the drive gear 906 to rotate, which in turn causes the driven gear 905 to rotate, which in turn causes the screw 901, screw 902, screw 903, or screw 904, which are fixedly connected to the driven gear 905, to rotate. This causes the slider 15 on the outer surface of the screw 901, screw 902, screw 903, or screw 904 to move, which in turn causes the slitting blade 16 to move, thereby adjusting the slitting width of the mulch film. At the same time, the slitting width of the mulch film can be precisely adjusted according to the position of the pointer 13 and the scale line 14.

[0027] Among them, the outer surfaces of screw 1 (901), screw 2 (902), screw 3 (903), and screw 4 (904) are all threaded with slider 15. The left surface of slider 15 is slidably connected to the right surface of the mounting frame. The right surface of slider 15 is fixedly connected with a slitting blade 16. A pointer 13 is fixedly connected to the upper side of the right surface of slider 15. The upper surface of the mounting frame is provided with scale lines 14. When the control switch 2 is operated, the motor 17 is started. The output shaft of the motor 17 rotates, driving the collecting roller 10 to rotate and collect the mulch film. At the same time, when the mulch film passes under the slitting blade 16, it is cut by the slitting blade 16 into the required width.

[0028] The working principle of the slitting machine for processing mulch film provided by this utility model is as follows: When mulch film needs to be slitted, the mulch film on the unwinding roller 3 is passed between the fixed roller 6 and the movable roller 7, then through the underside of the guide roller 8, and finally fixed to the outer surface of the collecting roller 10. Rotating the knob causes the screw 5 to rotate, driving the slider 2 to move downwards along the direction of the screw 5, which in turn drives the movable roller 7 downwards. This causes the movable roller 7 and the fixed roller 6 to apply pressure to the mulch film, keeping it taut. Control switch 2 starts motor 17, the output shaft of motor 17 rotates, driving the collecting roller 10 to rotate and collect the mulch film. Simultaneously, as the mulch film passes under the slitting blade 16, it is cut to the required width. When the cutting width needs adjustment, rotate the locking rod 913, causing it to rotate upwards. Then, the locking rod 913 moves within the transverse groove of the limiting groove, driving the first rotating drum 908 to move, causing the second rotating drum 909 to move. Spring 911 pushes the movable rod 910 upwards. At the upper end, the upper end of the movable rod 910 is pressed tightly against the inner arc surface of the drive gear 906 to be adjusted. After moving to the specific position, the locking rod 913 is rotated downwards, fixing the locking rod 913 in the vertical groove of the limiting groove. At this time, the handle 12 is rotated, which drives the rotating rod 907 to rotate, causing the first rotating cylinder 908 to rotate, which in turn drives the second rotating cylinder 909 to rotate, causing the locking rod 913 to rotate. When the locking rod 913 rotates to the position corresponding to the locking groove, the locking rod 913 is engaged in the locking groove. Then the handle 12 continues to rotate. The rotation of the drive gear 906 causes the driven gear 905 to rotate, which in turn causes the screw 901, 902, 903, or 904, which are fixedly connected to the driven gear 905, to rotate. This causes the slider 15 on the outer surface of the screw 901, 902, 903, or 904 to move, which in turn moves the slitting blade 16, thereby adjusting the slitting width of the mulch film. At the same time, the slitting width of the mulch film can be precisely adjusted according to the position of the pointer 13 and the scale line 14.

[0029] It is worth noting that the motor 17 disclosed in the above embodiments is YE3-63M2-2, and the control switch 2 is provided with a control button corresponding to the motor 17 and used to control its switch.

[0030] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
