Cutting knife and cutting bed for cutting bed

Abstract

The invention discloses a cutting knife for a cutting bed, which comprises a cutting knife body. The cutting knife body is provided with a coplanar main cutting edge, a secondary cutting edge and a knife tip cutting edge, and the included angle between the main cutting edge and the secondary cutting edge is is 180°, one of the main cutting edge and the secondary cutting edge extends from the tip of the cutting edge to the direction away from the cutting edge, and the other is connected to the end of the cutting edge. When the cloth is cut with the cutting knife for the cutting bed, it can be ensured that the cloth at the relative positions on both sides of the cutting knife for the cutting bed can be completely cut off. Compared with the prior art, there is no incompletely cut cloth. Therefore, It can prevent the cloth from being brought into the bristle brick with the downward movement of the knife tip, avoid the situation that the bristle brick is difficult to clean, and improve the service life of the bristle brick. When the tip of the knife rises, it can avoid the slight displacement of the cloth with the tip of the knife under the action of friction, that is, avoid the phenomenon of banding, and improve the integrity of the cloth and the cutting accuracy. The invention also discloses a cutting machine comprising the cutting knife for the cutting machine.

Description

technical field [0001] The invention relates to the technical field of cutting bed technology equipment, and more specifically, relates to a cutting knife for a cutting bed. In addition, the present invention also relates to a cutting machine including the above-mentioned cutting knife for cutting machine. Background technique [0002] At present, high-rise cutting machines are more and more widely used in the field of clothing, that is, the height or number of layers of fabrics cut by the cutting machine is increasing. [0003] However, due to the limitation of the existing cutter blade structure of the cutting bed, it is easy to make the cloth cutting incomplete. Therefore, when using the existing cutter to cut the cloth, it is easy to bring the cloth, especially when cutting small pieces of cloth. , the cloth phenomenon is particularly serious. [0004] In addition, when using existing cutters to cut fabrics such as chiffon, it is easy to bring uncut fabrics into the br...
