Description

Technical Field

[0001] The utility model relates to the field of stationery production, in particular to an automatic flattening and cutting device for a metal wire mesh. Background Art

[0002] Wire mesh plays an important role in the stationery industry and is widely used to make office supplies such as file baskets, folders, pen holders, and stationery accessories such as pen refills and pen caps. Traditional wire mesh processing usually relies on manual operation and requires multiple processes, including flattening and cutting. It is inefficient and easily limited by technical level, resulting in long production cycles, high costs, and difficult to ensure product quality.

[0003] The existing devices have made some improvements in the flattening and cutting of workpieces, but there are still some problems in practical applications. For example, the patent with publication number CN217315205U discloses a copper strip cutting and flattening device, which has some problems in the metal mesh cutting and flattening in the stationery industry. 1. Metal mesh adhesion: During the cutting process, there are impurities such as oil and rust on the surface of the metal mesh, or there is adhesive residue on the metal mesh itself, which will cause adhesion between the metal meshes. When the cutting tool contacts the metal mesh, these adhesions may cause the tool to get stuck or the cutting to be poor, affecting the processing effect. 2. Insufficient cutting: The lines of the metal mesh are thin and dense. If the design of the tool is unreasonable or the quality of the tool is poor during cutting, it is easy to cause insufficient cutting. Part of the metal mesh may not be completely cut off, resulting in unstable product quality and even affecting subsequent processing procedures. Utility Model Content

The cross-cutting mechanism 4 is fixed on the upper right end of the frame, and its function is to perform transverse cutting after the metal wire mesh is flattened, and cut the metal wire mesh according to the preset length or at the required position. The transmission mechanism 5 is fixed at the bottom of the frame, providing power transmission for the entire device. Specifically, the motor drive shaft drives the belt and the pulley connected to the belt to rotate, and the pressure roller 32 and the auxiliary roller 33 are driven to rotate through the gear transmission, ensuring that the automation process of the equipment can proceed smoothly.

The feeding cylinder 11 is fixed to the middle of the left side of the frame 1, and its main function is to store the raw material of the metal wire mesh to be processed. The feeding cylinder 11 serves as the starting point for conveying materials, ensuring that the metal wire mesh enters the equipment in the correct manner and is parallel to the pressing roller 32 and the auxiliary roller 33, so as to prepare for the subsequent flattening and cutting processes. The collecting box 12 is arranged at the upper right end of the frame, and its function is to collect the metal wire mesh after flattening and cutting.

It has the following functions: 1. Reduce wear: The spherical stripping head can reduce the wear caused by the direct contact between the wire mesh and the hard surface during the stripping process. Since the spherical design has a certain elasticity, it can provide a buffering effect during stripping and reduce the possible damage to the wire mesh. 2. Ease the angle: The special shape of the stripping head helps to control the angle at which the wire mesh is stripped from the winding mechanism, making the stripping action smoother and avoiding deformation or breakage of the material due to too steep an angle. 3. Improve the yield rate: By easing the stripping angle and reducing wear, this design is conducive to improving the yield rate of the entire production process and ensuring the quality of the wire mesh.
