Description

Technical Field

[0001] The utility model relates to the technical field of mechanical engineering, in particular to an automatic edge trimming and grinding device for a metal mesh. Background Art

[0002] Metal mesh is widely used in a variety of industries, including construction, automotive manufacturing, food processing, and mining screening. Due to its high strength, corrosion resistance, and excellent air permeability, metal mesh has become a key foundational material in these industries. During the production process, metal mesh often requires cutting and edge processing to meet different usage requirements.

[0003] Chinese patent CN220093727U discloses "a metal mesh trimming device". Through the setting of structures such as a motor and a rotating shaft, the blade and the grinding plate make reciprocating linear motion left and right, and trim the metal mesh transported on the conveyor belt. The trimmed metal mesh contacts the grinding plate again, and the grinding plate grinds and deburrs the trimmed surface, thereby achieving the effect of improving the trimming efficiency.

[0004] In the aforementioned structural design, the blade and grinding plate reciprocate along the same straight line during the cutting and grinding process. This simplifies the mechanical structure to a certain extent, but it also introduces potential wear issues. Physically, when two surfaces continuously contact and exert pressure in the same manner, friction gradually wears away the material in the contact area. Because the blade and grinding plate move in a straight line, and the metal mesh continuously moves along the same path, friction and shear forces are concentrated on the same parts of the blade and grinding plate, causing increased wear in these areas. The blade's cutting edge contacts the same part of the metal mesh with every cut, and the repeated shearing action causes specific areas of the blade's edge to wear faster. As wear accumulates, the blade's sharpness gradually decreases, affecting cutting quality, resulting in uneven cuts, and even burrs. Similarly, during the deburring process, the grinding plate's surface in contact with the metal mesh experiences increased friction. Over time, these areas will experience excessive wear, leading to reduced grinding efficiency, ineffective burr removal, and substandard finish on the metal mesh edge.

[0005] In view of this, we propose an automatic edge trimming and grinding device for metal mesh. Utility Model Content

[0006] The purpose of the utility model is to provide an automatic edge trimming and grinding device for metal mesh, which solves the problem that the blade and the grinding plate are cut and ground on a fixed linear track, resulting in increased local wear, thereby affecting the processing quality and equipment performance.

The driving roller 25 drives the conveyor belt 26 to move, and the conveyor belt 26 drives the metal mesh to be transported. The two conveyor belts 26 clamp the metal mesh, which plays a role in stable transportation, reduces the unstable vibration of the metal mesh, and improves the efficiency of automatic edge trimming and grinding.

[0030] The inner wall of the housing 1 is fixedly connected to the reciprocating cylinder 31, and the inner wall of the positioning member 34 is slidably connected to the outer wall of the vertical slide 33. The reciprocating cylinder 31 drives the connecting rod 32 to reciprocate up and down, and the connecting rod 32 drives the vertical slide 33 to reciprocate up and down.

The reciprocating motion can reduce the continuous contact time of the crescent cutter 39 with the material during the cutting process, reduce the cutting resistance and cutting heat accumulation, thereby improving the stability and comfort of the cutting process, and different parts of the crescent blade cut into the material at different angles. This change helps to reduce the long-term accumulation of stress at a specific cutting angle, thereby reducing the local wear of the crescent cutter 39, improving the cutting effect, making the cutting uniform, and reducing the generation of burrs.
