Machine fabric cutting cutter head

Abstract

The invention discloses a machine-used cloth cutting cutter head, comprising a cutter head, the cutter head is a circular sheet, a disk body is arranged in the middle, a mounting hole is arranged in the middle of the disk body, hypotenuses are arranged on both sides of the outside, the outer ring is a blade edge, and the installation hole is expanded. Correspondingly set four fixing holes on the circumference, the bottom of the hypotenuse is fixed with the disc body, and gradually shrinks and becomes thinner, the top forms a circle of blade edge, and several blade tips are evenly distributed on the edge of the blade, and a blade valley is set in the middle of two adjacent blade edges , the valley bottom of the blade valley and the left and right adjacent blade tips are provided with blade one and blade two, the fixing hole and the installation hole are concentric circles, the angle of the blade tip is 145-155 degrees, and the angle between blade one and blade two is 155- 165 degrees, blade tip, blade 1, and blade 2 are all sharp cutting edges, and blade 1, blade 2, and blade tip of the present invention form undulating and connected blade edges, which solves the problem of embedding concave-convex teeth in cloth and threads during cloth cutting The dragging of the fabric in the cutter head also avoids the high-temperature carbonization of both sides of the face cloth caused by the disc-shaped cutter head in the cloth cutting process.

Description

technical field [0001] The invention relates to a cutter head for trimming the face cloth, especially a cloth cutting cutter head for a machine. Background technique [0002] The face cloth has a uniform width, and the length of the cloth is different after weaving. It needs to be trimmed on both sides. The current trimming is generally rolled out, and a reciprocating blade or a rotating cutter head is set on both sides to cut off the edge of the cloth. However, the commonly used blades and discs are zigzag, and the blades are elongated. When trimming, they need to reciprocate up and down, and the installation space is large. , cause the surface cloth to drag or get stuck and fail. The cutter head is generally in the shape of a zigzag or toothless disc. The zigzag is easy to jam and fail. The toothless disc cutter will rub at high speed and generate high temperature during use. , resulting in carbonization on both sides of the face cloth. Contents of the invention [000...
