[0019] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0020] In the description of this utility model, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] like Figures 1 to 3 As shown, this utility model discloses a wire mesh edge-cutting device, including a horizontally arranged workbench 1 and a wire mesh unwinding shaft 2 horizontally arranged in front of the workbench 1. A rolled wire mesh 3 is mounted on the unwinding shaft 2. A rotary cutter 4 is arranged above the workbench 1, with its axis extending laterally. The rotary cutter 4 is driven to rotate by a power component to cut the wire mesh output from the unwinding shaft. A waste collection component is arranged below the rear of the workbench 1 to collect the waste material 5 cut from the left and right ends of the wire mesh 3. During operation, the wire mesh led from the unwinding shaft passes under the rotary cutter. The power component drives the rotary cutter to rotate, cutting the left and right ends of the wire mesh. Simultaneously, the rotary cutter can also cut the wire mesh into pieces. The waste collection component collects the waste material cut from the left and right ends of the wire mesh. This device uses a rolling cutter to trim the left and right ends of the wire mesh. At the same time, the rolling cutter can also cut the wire mesh into pieces. Compared with traditional manual cutting, it is more convenient to operate and effectively improves work efficiency.

[0022] In this embodiment, the rotary cutter 4 includes a cylindrical rotary cutter body 6. A plurality of cutting blades 7 are evenly distributed around the outer circumference of the rotary cutter body 6. The cutting blades 7 are parallel to the axis of the rotary cutter body 6 and are used to cut the wire mesh into pieces. Annular edge-cutting blades 8 are provided on the outer circumference of both the left and right ends of the rotary cutter body 6. These edge-cutting blades are used to cut the left and right ends of the wire mesh. Furthermore, the outer circumference of the rotary cutter body is textured for contact with the wire mesh. When the rotary cutter rotates, the textured surface contacts the wire mesh, which also helps to convey the wire mesh backward to some extent.

[0023] In this embodiment, a rolling cutting shaft 9 is fixedly inserted through the middle of the rolling cutting blade body 6. The rolling cutting shaft 9 is mounted on an inverted U-shaped rolling cutting support frame 10. The power assembly includes a power mounting frame 11, a rolling cutting motor 12, and a sprocket and chain transmission component 13. The power mounting frame 11 is located above the rolling cutting support frame 10. The rolling cutting motor 12 is arranged horizontally and is connected to the bottom of the power mounting frame 11 through a connecting frame 14. The output shaft of the rolling cutting motor 12 extends to the right and is connected to the left end of the rolling cutting shaft 9 through the vertically arranged sprocket and chain transmission component 13. The rolling cutting motor 12 drives the rolling cutting shaft 9 to rotate through the sprocket and chain transmission component 13.

[0024] In this embodiment, the top left end of the rolling support frame 10 is provided with a vertically penetrating clearance hole 15, and the sprocket and chain drive component 13 passes through the clearance hole 15 vertically.

[0025] In this embodiment, a vertically arranged lifting cylinder 16 is also installed at the bottom of the power mounting bracket 11. The cylinder rod of the lifting cylinder 16 extends downward and its end is connected to the middle of the rolling cutter support frame 10. The lifting cylinder drives the rolling cutter to move vertically up and down through the rolling cutter support frame. By making the rolling cutter adjustable, the wire mesh can be passed through directly below the rolling cutter before operation.

[0026] In this embodiment, the rear end of the workbench 1 is equipped with a transversely arranged transition roller 17 to facilitate the bypassing of waste materials.

[0027] In this embodiment, the waste collection assembly includes a waste conveying roller group disposed below and in front of the transition roller 17 and rotating in opposite directions. The waste conveying roller group includes two waste conveying rollers 18, which are distributed in a front-to-back manner. Waste passes between the two waste conveying rollers 18, and the waste conveying roller group conveys the waste downward. A waste collection frame 28 is disposed directly below the waste conveying roller group.

[0028] In this embodiment, a discharge port 19 is provided on the workbench 1 directly behind the rotary cutter 4. The discharge port facilitates the falling of the wire mesh cut by the rotary cutter, thus achieving material discharge. Furthermore, the discharge port 19 is vertically continuous, and a discharge pipe 20 is vertically arranged below the discharge port 19. A wire mesh collection frame 21 is arranged directly below the discharge pipe 20 to collect the cut wire mesh. It should be noted that since the waste material after rotary cutting is conveyed downwards by the waste material conveying roller group, the entire wire mesh can be pulled from front to back. After each piece of wire mesh is cut by the rotary cutter, since the entire wire mesh is constantly being conveyed, the uncut wire mesh will push the cut wire mesh backwards, thus falling into the discharge port, and then along the discharge port and discharge pipe into the wire mesh collection frame.

[0029] In this embodiment, a suction pipe 22 is connected to the upper side wall of the discharge pipe 20. The suction pipe 22 is connected to a suction pump (not shown in the figure), and a baffle plate (not shown in the figure) is provided at the connection between the suction pipe 22 and the discharge pipe 20. During operation, the suction pump draws suction from the discharge pipe through the suction pipe, creating a certain negative pressure at the upper end of the discharge pipe, which facilitates the better suction of the rolled wire mesh into the discharge pipe. The presence of the baffle plate prevents the wire mesh from entering the suction pipe. It should be noted that the suction pump stops after working for a period of time. After the suction pump stops, the wire mesh adsorbed on the baffle plate falls along the discharge pipe into the wire mesh collection frame.

[0030] In this embodiment, a pair of left-right distributed conveyor plates 23 are arranged on the worktable 1 directly in front of the rotary cutter 4. The conveyor plates 23 are arranged longitudinally, and the pair of conveyor plates 23 correspond to the left and right ends of the wire mesh, respectively. There is a gap between the conveyor plates 23 and the worktable 1 to facilitate the passage of the wire mesh. The front ends of the pair of conveyor plates 23 are connected by a horizontally arranged connecting plate 24. By setting the conveyor plates, the wire mesh can be better positioned close to the worktable during conveying, reducing upward tilting.

[0031] In this embodiment, a longitudinally arranged mounting bracket 25 is fixed to the right end of the front end face of the workbench 1, and the right end of the wire mesh unwinding shaft 2 is rotatably connected to the mounting bracket 25 through a bearing.

[0032] In this embodiment, an air nozzle 26 is provided in front of the rotary cutter 4. The air nozzle 26 is connected to the air inlet pipe 27. The air nozzle 26 is inclined with a high front end and a low rear end. The air nozzle 26 blows air between the rotary cutter 4 and the worktable 1 to cool down the cut wire mesh and disperse some debris generated during the rotary cutting process.

[0033] If this utility model discloses or relates to mutually fixedly connected parts or structural components, then, unless otherwise stated, a fixed connection can be understood as: a detachable fixed connection (e.g., using bolts or screws), or a non-detachable fixed connection (e.g., riveting, welding). Of course, mutually fixed connections can also be replaced by an integral structure (e.g., manufactured using a casting process) (except where it is obviously impossible to use an integral forming process).

[0034] In addition, unless otherwise stated, the terms used to indicate positional relationships or shapes in any of the technical solutions disclosed in this utility model above include states or shapes that are similar to, close to, or approximate with them.

[0035] Any component provided by this utility model can be assembled from multiple individual components, or it can be a single component manufactured by a one-piece molding process.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
