Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of metal mesh processing, and more specifically, to a cutting mechanism for metal mesh processing. Background Technology

[0002] In the production and processing of metal mesh, the edge trimming process is a crucial step in ensuring product quality and subsequent performance. With the increasing demand for metal mesh from industries such as construction, mining, and protective equipment, its processing quality and production efficiency are receiving increasing attention.

[0003] Currently, in most metal mesh processing steps, traditional equipment directly winds up the metal mesh after weaving or stamping, without pre-treating the edges. This production method has significant drawbacks: the untreated edges of the metal mesh are often uneven, with burrs and rough edges, and sometimes even loose or curled wires. During the winding process, these irregular edges easily entangle and become stuck together, not only affecting the smoothness of the winding process and reducing winding efficiency, but also potentially causing wear and tear on the winding equipment and shortening its lifespan. Furthermore, the uneven edges result in an uneven surface on the wound metal mesh roll, affecting the product's appearance quality and causing inconvenience for subsequent transportation and storage. In addition, in actual use, untreated burrs and rough edges also pose safety hazards, easily injuring operators or damaging related equipment.

[0004] Therefore, designing a trimming mechanism that can neatly process the edges of the metal mesh before it is rolled up has become an urgent need to solve the above problems and improve the processing quality and production efficiency of metal mesh. Utility Model Content

[0005] To overcome the aforementioned defects, embodiments of this disclosure provide an edge-cutting mechanism for metal mesh processing, solving the problem that in the prior art, untreated metal mesh edges are often uneven, with burrs, rough edges, and even loose or curled metal wires in some areas. During the winding process, these irregular edges are prone to tangling and hooking together, which not only affects the smooth winding process but also reduces winding efficiency.

[0006] According to one aspect, at least one embodiment of this disclosure provides a cutting mechanism for metal mesh processing, comprising: A platform and a top plate, wherein the top plate is disposed on the platform; A conveying and trimming assembly is disposed on the platform and the top plate; A height adjustment assembly is disposed on the platform and the top plate; The conveying and cutting assembly includes a pair of conveying rollers, which are rotatably connected to the frame and the top plate respectively. The conveying rollers located in the frame are driven to rotate by electricity. Both the surface of the frame and the surface of the top plate are provided with cutting holes. A cutting saw blade is installed on the top plate and is driven to rotate by electricity.

[0007] As a further technical solution, the cutting saw blade is located inside the cutting elongated hole, and a positioning baffle is provided on the surface of the frame. The upper end of the positioning baffle is movably fitted into the cutting elongated hole on the surface of the top plate.

[0008] As a further technical solution, a notch is provided on the side surface of the top plate, and a dividing baffle is provided on the surface of the platform. The dividing baffle is located at the notch and is fixed at an inclined angle.

[0009] As a further technical solution, the height adjustment component includes a pair of columns, the columns are fixed at both ends of the top of the platform, the top plate is movably fitted inside the columns, and the columns are vertically movably connected to the columns.

[0010] As a further technical solution, a vertical screw is rotatably connected to the surface of the platform, and the vertical screw is connected to the top plate by a threaded connection. Both ends of the surface of the top plate are provided with external grooves, and both ends of the surface of the platform are provided with support studs.

[0011] As a further technical solution, the support stud is located inside the outer groove, and a movable nut is screwed onto the support stud by means of threads. The movable nut is located at the upper and lower ends of the outer groove, respectively.

[0012] As a further technical solution, the platform has an overall L-shaped structure, and the top plate is located on one side of the platform.

[0013] As a further technical solution, the side surface of the positioning baffle is flush with the inner surface of the cutting saw blade.

[0014] The beneficial effects of the embodiments disclosed herein are as follows: In this disclosure, the conveying and cutting edge assembly achieves continuous conveying of the metal mesh through the electric drive of the conveying rollers. The high-speed rotation of the cutting saw blade precisely cuts the edges of the metal mesh, solving the problems of uneven edges and burrs on the metal mesh. The positioning baffle is flush with the inner surface of the cutting saw blade to ensure the straightness of the metal mesh cutting edge, prevent the edges from tangling and hooking together during winding, improve winding efficiency, reduce wear on the winding equipment, improve the appearance quality of the wound metal mesh, and reduce subsequent transportation and storage inconvenience and safety hazards.

[0015] In this disclosure, the height adjustment component, through the cooperation of a column, a vertical screw, and a movable nut, can flexibly adjust the height of the top plate to adapt to the processing needs of metal mesh of different thicknesses. This design improves the versatility of the equipment, allowing it to process metal mesh of different specifications without replacing equipment parts, reducing equipment adjustment time and costs. Simultaneously, it ensures precise spacing between the conveyor roller and the cutting saw blade, guaranteeing cutting accuracy, avoiding processing errors caused by unsuitable height, and improving the cutting quality of the metal mesh and the applicability of the equipment.

[0023] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0024] like Figures 1-4 As shown, a metal mesh processing edge-cutting mechanism according to an embodiment of the present disclosure includes: A platform 1 and a top plate 2, wherein the top plate 2 is disposed on the platform 1; A conveying and trimming assembly 3 is disposed on the platform 1 and the top plate 2; Height adjustment component 4, which is disposed on the platform 1 and the top plate 2; The conveying and cutting assembly 3 includes a pair of conveying rollers 3-1, which are rotatably connected to the frame 1 and the top plate 2 respectively. The conveying rollers 3-1 located in the frame 1 are driven to rotate by electricity. Both the surface of the frame 1 and the surface of the top plate 2 are provided with cutting elongated holes 3-2. A cutting saw blade 3-3 is installed on the top plate 2. The cutting saw blade 3-3 is driven to rotate by electricity and is located in the cutting elongated holes 3-2. A positioning baffle 3-4 is provided on the surface of the frame 1. The upper end of the positioning baffle 3-4 is movably fitted into the cutting elongated holes 3-2 on the surface of the top plate 2. A notch 3-5 is provided on the side surface of the top plate 2. A separating baffle 3-6 is provided on the surface of the frame 1. The separating baffle 3-6 is located at the notch 3-5 and is fixed at an inclined angle.

[0025] In some examples, to achieve continuous conveying and trimming of the metal mesh, a conveying and trimming assembly 3 is designed. This assembly includes a pair of conveying rollers 3-1, which are respectively installed in the frame 1 and the top plate 2. The conveying rollers 3-1 in the frame 1 are driven to rotate by a motor, and the metal mesh is conveyed forward by friction. The conveying rollers 3-1 in the top plate 2 serve as driven rollers for auxiliary support. The cutting holes 3-2 on the surfaces of the frame 1 and the top plate 2 provide working space for the cutting saw blade 3-3, which is vertically installed at the bottom of the top plate 2 and driven to rotate at high speed by an independent motor.

[0026] During the metal mesh conveying process, the upper end of the positioning baffle 3-4 on the surface of the frame 1 is inserted into the cutting elongated hole 3-2 of the top plate 2, forming a lateral limit to ensure that the edge of the metal mesh remains parallel to the cutting saw blade 3-3. The notch 3-5 on the side surface of the top plate 2 cooperates with the separating baffle 3-6 of the frame 1. The separating baffle 3-6 is fixed at an inclination of 30°~45°, which can guide the cut edge material to one side for collection, while the main metal mesh continues to be conveyed forward. For example, when the metal mesh passes through the cutting elongated hole 3-2, the positioning baffle 3-4 restricts its lateral movement, the high-speed rotating saw blade cuts the edge along the trajectory of the elongated hole, and the inclination separating baffle 3-6 separates the edge material from the main body, realizing automated edge cutting operation.

[0027] like Figures 1-4As shown in the figure, the height adjustment component 4 in this embodiment includes a pair of columns 4-1. The columns 4-1 are fixed at both ends of the top of the platform 1. The top plate 2 is movably fitted inside the columns 4-1. The columns 4-1 are vertically movably fitted onto the columns 4-1. A vertical screw 4-2 is rotatably connected to the surface of the platform 1. The vertical screw 4-2 is threadedly connected to the top plate 2. Both ends of the surface of the top plate 2 are provided with outer grooves 4-3. Both ends of the surface of the platform 1 are provided with support studs 4-4. The support studs 4-4 are located inside the outer grooves 4-3. A movable nut 4-5 is threadedly connected to the support studs 4-4. The movable nuts 4-5 are located at the upper and lower ends of the outer grooves 4-3, respectively.

[0028] In some examples, in order to achieve precise adjustment of the height of the top plate 2 and adapt to the effect of metal mesh of different thicknesses, a height adjustment component 4 is designed. A pair of columns 4-1 are vertically fixed on the top of the frame 1. The top plate 2 is mounted on the columns 4-1 through linear bearings and can slide up and down along the columns 4-1. The vertical screw 4-2 on the frame 1 is engaged with the threaded hole at the bottom of the top plate 2. When the screw is rotated, the top plate 2 rises and falls due to the threaded transmission. The adjustment range is set according to the height of the columns 4-1.

[0029] The outer grooves 4-3 at both ends of the top plate 2 engage with the support studs 4-4 of the frame 1. The support studs 4-4 are inserted into the outer grooves 4-3, and the position of the top plate 2 is locked by the movable nuts 4-5 at both ends. During adjustment, first loosen the nuts, rotate the vertical screw 4-2 to raise or lower the top plate 2 to the target height, and then tighten the nuts to secure it. For example, when processing 5mm thick metal mesh, adjust the top plate 2 to a higher position; when processing 1mm thin mesh, lower the top plate 2 to ensure that the distance between the conveyor roller 3-1 and the saw blade matches the mesh thickness. This ensures smooth sliding and prevents the top plate 2 from shaking. Combined with the self-locking characteristic of the vertical screw 4-2, the top plate 2 remains stable during processing, avoiding a decrease in cutting accuracy due to vibration.

[0030] For example, such as Figure 1 As shown, the platform 1 has an overall L-shaped structure, and the top plate 2 is located on one side of the platform 1.

[0031] In some examples, the frame 1 adopts an L-shaped structure, with the top plate 2 located on one side inside the frame 1. Through rigid support and integration with the reference plane, a stable working platform for metal mesh cutting is constructed. The surface of the horizontal section serves as the reference plane for metal mesh conveying, ensuring that the metal mesh remains horizontal during conveying. The vertical section provides vertical support for the top plate 2, which is fixed to the inside of the vertical section with bolts, forming a semi-enclosed working space with the horizontal section of the frame 1.

[0032] When the metal mesh is laid on the horizontal section of the platform 1, the inner right-angled side of the L-shaped structure naturally forms a positioning reference. The edge of the metal mesh can be directly attached to this reference edge for transportation, reducing manual positioning errors.

[0033] For example, such as Figure 1 As shown, the side surface of the positioning baffle 3-4 is flush with the inner surface of the cutting saw blade 3-3.

[0034] In some examples, the side surface of the positioning baffle 3-4 is flush with the inner surface of the cutting saw blade 3-3 to ensure the straightness of the metal mesh edge and the neatness of the winding after cutting. The positioning baffle 3-4 is made of wear-resistant steel and is on the same vertical plane as the inner cutting edge of the cutting saw blade 3-3. When the metal mesh moves with the conveying roller 3-1, the side surface of the positioning baffle 3-4 is in close contact with the edge of the metal mesh, forming a rigid limit and forcing the metal mesh to move in a straight line along the cutting direction of the saw blade.

[0035] During the trimming process, if the metal mesh shifts due to uneven tension, the positioning baffle 3-4 can immediately correct the shift, ensuring that the saw blade always cuts along the preset trajectory. Because the trimmed metal mesh edge is flush with the side surface of the positioning baffle 3-4, the edge can tightly adhere to the winding roller during winding, preventing skewing.

[0036] In actual use: Fix the frame 1 to the processing site. Adjust the height of the top plate 2 using the column 4-1 and vertical screw 4-2 of the height adjustment component 4 to make the spacing of the conveying rollers 3-1 match the thickness of the metal mesh. Tighten the moving nut 4-5 to fix the position of the top plate 2. Place the metal mesh on the surface of the frame 1, ensuring its edges are against the positioning baffle 3-4. Start the electric drive device of the conveying rollers 3-1 inside the frame 1. The conveying rollers 3-1 rotate, driving the metal mesh forward. Simultaneously, start the electric drive device of the cutting saw blade 3-3. The cutting saw blade 3-3 rotates at high speed within the cutting hole 3-2. During the metal mesh conveying process, the positioning baffle 3-4 restricts its lateral movement. The cutting saw blade 3-3 cuts the edge of the metal mesh along the trajectory of the cutting hole 3-2. The cut edge material is guided to one side and collected by the notch 3-5 on the side surface of the top plate 2 and the separating baffle 3-6 of the frame 1. The main metal mesh continues to be conveyed to complete the edge cutting. After processing is completed, turn off all drive devices and remove the edge-cut metal mesh.
