Description

Technical Field

[0001] This utility model relates to the field of silage film cutting technology, specifically to a silage film limiting cutting device. Background Technology

[0002] To effectively maintain the nutritional content and freshness of cattle feed and prevent it from becoming moldy or rotten due to air, moisture, and the external environment, silage is typically used for storage. During this process, operators need to tightly cover the piled-up cattle feed with silage film to create a relatively closed fermentation environment.

[0003] Currently, there are no dedicated silage films on the market. In practical applications, the ring-shaped film material needs to be cut into single-layer film before being made into silage film. Therefore, the ring-shaped film must be cut and separated manually. However, because the diameter of the ring-shaped film material is relatively long, manual cutting is prone to uneven film edges and cutting deviations due to improper operation. Cut deviations will reduce the sealing effect and thus affect the quality of silage. Utility Model Content

[0004] In view of the problems in the related technologies, this utility model proposes a silage film limiting and cutting device to overcome the above-mentioned technical problems existing in the existing related technologies.

[0005] Therefore, the specific technical solution adopted by this utility model is as follows: A silage film limiting and cutting device includes a support frame, a blade connected to the middle of the support frame, a movable frame slidably connected to both sides of the support frame, a first mounting seat installed below the top of the movable frame, a first limiting roller rotatably connected inside the first mounting seat, a second mounting seat provided below the first mounting seat, a second limiting roller rotatably connected inside the second mounting seat, and the second mounting seat connected to the movable frame.

[0006] Furthermore, in order to facilitate the adjustment of the height of the first limiting roller, the top of the movable frame is provided with a threaded hole, and a screw is threaded inside the threaded hole. One end of the screw is rotatably connected to the first mounting base.

[0007] Furthermore, in order to prevent the first mounting base from shifting during movement, a limit block is connected to one side of the first mounting base, and a limit groove is provided on the moving frame, with the limit block matching the limit groove.

[0008] Furthermore, in order to adjust the position of the movable frame, the bottom of the support frame is provided with a groove, and a two-way threaded rod is provided inside the groove. The two-way threaded rod is connected to the fixed plate through a bearing. The fixed plate is connected to the support frame. A threaded sleeve is threadedly connected to the two-way threaded rod, and the threaded sleeve is connected to the movable frame.

[0009] Furthermore, in order to drive the bidirectional threaded rod to rotate, a driven bevel gear is connected to the bidirectional threaded rod. The driven bevel gear meshes with the driving bevel gear, and the driving bevel gear is connected to the rotating rod.

[0010] Furthermore, one end of the rotating rod passes through the connecting plate and connects to the turntable, the connecting plate is connected to the support frame, and the turntable is located on the outside of the support frame.

[0011] Furthermore, the bottom of the support frame is connected to three rollers.

[0012] Furthermore, a handle is attached to one side of the support frame.

[0013] The beneficial effects of this utility model are as follows: (1) By setting a blade in the middle of the support frame, the silage film can be precisely cut. The movable frame is slidably connected on both sides. With the double roller limiting structure of the first limiting roller and the second limiting roller, the silage film can be effectively clamped and limited from top to bottom to prevent the film material from shifting or wrinkling during the cutting process, thereby improving the cutting accuracy and stability. In addition, by setting a threaded hole and a screw structure at the top of the movable frame and rotating one end of the screw to the first mounting seat, the height of the first limiting roller can be adjusted, which is convenient to adapt to silage films of different thicknesses or tension states, and improves the applicability and versatility of the equipment.

[0014] (2) By providing a groove at the bottom of the support frame and setting a two-way threaded rod and threaded sleeve in the groove, the two moving frames can move synchronously in opposite directions, thereby flexibly adjusting the distance between the two limiting rollers to meet the limiting requirements of silage films of different widths, and improving the adaptability and working efficiency of the device.

[0018] 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.

[0019] According to an embodiment of the present invention, a silage film limiting and cutting device is provided.

[0020] Example 1

[0021] like Figures 1-4 As shown, the silage film limiting and cutting device according to an embodiment of the present utility model includes a support frame 1. The support frame 1 is the basic frame of the entire silage film limiting and cutting device, which provides stable support. A blade 2 is connected in the middle of the support frame 1 for cutting the passing silage film. The blade 2 is located behind the first limiting roller 5. Slide grooves are provided on both sides of the support frame 1. Movable frames 3 are slidably connected inside the slide grooves. These movable frames 3 can slide along the support frame 1 to adapt to silage films of different widths.

[0022] like Figure 1 and Figure 4 As shown, a first mounting base 4 is installed below the top of the movable frame 3. A first limiting roller 5 is rotatably connected inside the first mounting base 4. The function of the first limiting roller 5 is to provide upper pressure and support during the cutting process, helping to maintain the flatness of the silage film. The first mounting base 4 allows the first limiting roller 5 to rotate freely, reducing friction while ensuring the smooth passage of the silage film. A second mounting base 6 is provided below the first mounting base 4. A second limiting roller 7 is rotatably connected inside the second mounting base 6. The second limiting roller 7 works in conjunction with the first limiting roller 5 to provide support and pressure to the silage film from below, ensuring stability during the cutting process. The second mounting base 6 is connected to the movable frame 3. The top of the movable frame 3 is provided with a threaded hole 8. A screw 9 is threadedly connected inside the threaded hole 8. One end of the screw 9 is rotatably connected to the first mounting base 4.

[0023] By rotating the screw 9, the height of the first mounting base 4 (and the first limiting roller 5) can be precisely adjusted to adapt to different operating requirements or changes in silage film thickness. A limiting block 10 is connected to one side of the first mounting base 4, and a limiting groove 11 is provided on the moving frame 3. The limiting block 10 matches the limiting groove 11, ensuring that the first limiting roller 5 will not deviate from the predetermined track when moving up and down, thus improving the stability and safety of the equipment operation.

[0024] like Figures 2-4 As shown, the bottom end of the support frame 1 is provided with a groove 12, and a bidirectional threaded rod 13 is provided inside the groove 12. The two ends of the bidirectional threaded rod 13 have opposite thread directions, so that the two moving frames 3 can be adjusted to move closer or further apart during rotation, thereby adapting to the cutting requirements of silage film of different widths. The bidirectional threaded rod 13 is connected to the fixed plate 14 through a bearing. The fixed plate 14 is connected to the support frame 1. A threaded sleeve 15 is threadedly connected to the bidirectional threaded rod 13. The threaded sleeve 15 is connected to the moving frame 3. A driven bevel gear 16 is connected to the bidirectional threaded rod 13. The driven bevel gear 16 meshes with the driving bevel gear 17. The driving bevel gear 17 is connected to the rotating rod 18. One end of the rotating rod 18 passes through the connecting plate 20 and is connected to the turntable 19. The connecting plate 20 is connected to the support frame 1. The turntable 19 is located on the outside of the support frame 1.

[0025] The operator can easily drive the rotating rod 18 to rotate by rotating the turntable 19 located on the outside of the support frame 1, which in turn drives the active bevel gear 17 and the driven bevel gear 16 to operate, and finally realizes the control of the bidirectional threaded rod 13. The bottom end of the support frame 1 is connected to three rollers 21, which facilitates the adjustment of the position of the support frame 1. A handle 22 is connected to one side of the support frame 1, which is convenient for the operator to push.

[0026] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0027] In summary, with the help of the above-mentioned technical solution of this utility model, in actual use, the operator first places the silage film on the support frame 1 and ensures that the silage film passes between the first limiting roller 5 and the second limiting roller 7. By rotating the screw 9, the height of the first limiting roller 5 can be adjusted to accommodate silage films of different thicknesses, ensuring that it remains flat during the cutting process.

[0028] Next, the operator can adjust the distance between the two movable frames 3 by rotating the turntable 19 located on the outside of the support frame 1, according to the width of the silage film. The rotation of the turntable 19 will drive the rotating rod 18 to rotate, which in turn drives the bidirectional threaded rod 13 to rotate through the meshing of the driving bevel gear 17 and the driven bevel gear 16. Since the threads at both ends of the bidirectional threaded rod 13 are in opposite directions, the threaded sleeves 15 on both sides can be moved synchronously during rotation, so that the two movable frames 3 move closer or further apart, thereby adapting to the cutting requirements of silage films of different widths.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
