Description

Technical Field

[0001] The utility model relates to the technical field of mesh production, in particular to a cutting device with a positioning structure for mesh production. Background Art

[0002] The mesh is a building material used for coal mine roof protection, tunnels, bridge construction, roadbed reinforcement, and construction sites. The main materials for the mesh are low-carbon steel wire, electro-galvanized wire, hot-dip galvanized wire, and modified drawn wire. The mesh is woven and shaped during the production process. The shaped mesh needs to be cut into appropriate lengths using cutting equipment, and then the cut mesh is cut through the cutting equipment.

[0003] When cutting the existing mesh, the produced mesh needs to be transferred to the inside of the cutting device through a conveyor, and then the mesh is cut under the action of the cutting device. However, when cutting, since the mesh itself is long and has a certain elasticity, if the mesh is not limited, the mesh itself will undergo elastic deformation when cut, resulting in an uneven cut of the cut mesh. Utility Model Content

[0004] In order to overcome the existing problems, an embodiment of the present application provides a cutting device for mesh production with a positioning structure, wherein a first limiting component and a second limiting component are provided on the upper surface of a receiving platform, and a second limiting roller is provided on the receiving platform at one end of the first limiting component. By changing the distance between the first limiting component and the second limiting roller, it can adapt to mesh widths of different sizes and match meshes of different sizes, and a second limiting component is provided. The second limiting component limits the upper part of the mesh to avoid warping of the mesh.

[0013] Preferably, a bearing is provided at the intersection of the receiving platform and the second limiting roller. Through the setting of the bearing, when the second limiting roller and the receiving platform are connected to each other, the second limiting roller can reduce the friction with the receiving platform through the bearing at the bottom end when rotating. A limiting groove is provided at the corresponding position of the receiving platform and the transmission shaft.

When the mesh is transmitted to the upper surface of the receiving platform 6, the roller 71 is taken out, and the two ends of the roller 71 are respectively connected to the first fixed frame 72 and the second fixed frame 73. Under the action of gravity, the roller 71 drops to the bottom end of the first fixed frame 72 and the second fixed frame 73 to limit the mesh on the upper surface of the receiving platform 6, and the roller 71 can roll inside the first fixed frame 72 and the second fixed frame 73, thereby reducing the friction with the mesh.

[0033] The frame 1 is provided with a receiving platform 6 at the intersection of the first limiting component 5, and a connecting hole 9 is opened at the intersection of the receiving platform 6 and the second limiting roller 8. The connecting hole 9 is interconnected with the bottom end of the second limiting roller 8, and after the second limiting roller 8 and the receiving platform 6 are connected to each other, the side surface of the second limiting roller 8 and the first fixed frame 72 at one end of the second limiting component 7 are in the same vertical plane.
