Description

Technical Field

[0001] The utility model relates to the technical field of sofa leather cutting, in particular to a leather cutting tool for sofa production. Background Art

[0002] Leather sofas are made of animal skins, such as pig skin, cow skin, sheep skin and other animal skins, which are processed through a specific process. Because the leather is breathable and, more importantly, very soft, it is very comfortable to sit on and not easy to get dirty. In the production process of sofa leather, the leather needs to be cut, and tooling plays a vital role in the cutting.

In the actual cutting process, since the leather raw material itself has a certain toughness and the cutting position will undergo a certain elastic deformation after cutting, the cutting position may change, resulting in a poor cutting effect. Therefore, a leather cutting tool for sofa production is proposed. Utility Model Content

The lateral position of the cutting blade 23 is adjusted by the operation of the electromagnetic slide rail 20, and the contact between the cutting blade 23 and the leather is adjusted by the second electric push rod 21. The cutting blade 23 is driven by the second motor to rotate to cut the leather, and the external winding device is placed on the rear side of the cutting table 1 to wind the leather. As the leather is wound, the leather moves on the roller 11, and the leather is cut by the cutting knife, so that the part of the cutting position is fixed, thereby avoiding a certain elastic deformation of the cutting position after the cutting is completed, which then causes the cutting position to change and affects the cutting effect.
