The utility model discloses can break the cardboard when dividing paper, conveniently take out, show to improve and divide paper effect and quality.
Description
Technical Field
The utility model relates to a paper knife field, concretely relates to corrugated container board paper knife.
Background
The existing disc paper separating knife has a single edge and a sawtooth edge, and the cut edge paper is strip-shaped, so that the cut edge paper is not easy to collect due to too long edge and cannot be cut. The existing paper separating knife does not have the function of breaking paper in the process of separating paper.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a corrugated container board divides paper sword to above-mentioned defect exactly.
The utility model comprises six arc-shaped cutter blocks which are butted in sequence and have the same structure, and the six arc-shaped cutter blocks are butted in sequence to form an annular structure;
a plurality of mounting and fixing holes penetrating through the arc-shaped cutter block are uniformly formed in the arc-shaped cutter block, a pair of double-edged blades perpendicular to the outer side edge are horizontally arranged on the outer side edge of the arc-shaped cutter block in parallel, and tooth grooves which are continuously arranged are formed in the double-edged blades;
two ends of the outer side edge of the arc-shaped blade block are respectively provided with a vertical serrated cutting blade, and the serrated cutting blades connect the ends of a pair of double-edged blades perpendicular to the outer side edge, so that the double-edged blades and the serrated cutting blades form a concave cavity part on the outer side edge of the arc-shaped blade block.
A pair of double-edged blades perpendicular to the outer side edge are respectively positioned at the uppermost part and the lowermost part of the outer side edge of the arc-shaped cutter body block.
The depth of the gullet is less than the width of the double-edged blade.
The arc-shaped blade block, the double-edge blade and the serrated cutting blade are of an integrally formed structure.
The arc-shaped cutter block, the double-edged cutter and the serrated cutting blade are made of tungsten steel materials, carbon steel materials, stainless steel materials or hard alloy materials.
The number of the plurality of mounting fixing holes is three.
The utility model has the advantages that: through the design of the tooth's socket of arranging in succession on the twolip blade and the twolip blade of a pair of perpendicular to outside border, and be equipped with vertical cockscomb structure cutting blade and can break the cardboard when dividing paper, conveniently take out, show improvement branch paper effect and quality. Meanwhile, the cutting edge is not easy to passivate, and the service life is prolonged.

Detailed Description
As shown in the attached drawings, the utility model comprises six arc-shaped cutter blocks 1 which are abutted in sequence and have the same structure, and the six arc-shaped cutter blocks 1 are abutted in sequence to form an annular structure;
a plurality of mounting and fixing holes 2 penetrating through the arc-shaped cutter block 1 are uniformly formed in the arc-shaped cutter block, a pair of double-edge blades 3 perpendicular to the outer side edge are horizontally arranged on the outer side edge of the arc-shaped cutter block 1 in parallel, and tooth grooves 4 which are continuously arranged are formed in the double-edge blades 3;
two ends of the outer side edge of the arc-shaped blade block 1 are respectively provided with a vertical serrated cutting blade 5, and the serrated cutting blades 5 connect the ends of a pair of double-edged blades 3 perpendicular to the outer side edge, so that the double-edged blades 3 and the serrated cutting blades 5 form a recessed cavity portion 6 on the outer side edge of the arc-shaped blade block 1.
A pair of double-edged blades 3 perpendicular to the outer edge are respectively positioned at the uppermost and lowermost portions of the outer edge of the arc-shaped blade block 1.
The depth of the gullets 4 is less than the width of the double-edged blade 3.
The arc-shaped blade block 1, the double-edged blade 3 and the serrated cutting blade 5 are of an integrally formed structure.
The arc-shaped cutter block 1, the double-edged cutter 3 and the serrated cutting blade 5 are made of tungsten steel materials, carbon steel materials, stainless steel materials or hard alloy materials.
The number of the plurality of mounting fixing holes 2 is three.
The working principle is as follows: after the six arc-shaped cutter blocks 1 are sequentially and fixedly arranged on the paper separating machine, the six arc-shaped cutter blocks 1 are sequentially abutted to form an annular structure; in the use through the design of continuous arrangement tooth's socket 4 on a pair of twolip blade 3 and the twolip blade 3 of perpendicular to outside border, be equipped with vertical cockscomb structure cutting blade 5 and can break the cardboard when dividing paper, conveniently take out, show improvement branch paper effect and quality. Meanwhile, the cutting edge is not easy to passivate, and the service life is prolonged. The double-edged blades 3 and the serrated cutting blades 5 form a concave cavity part on the outer side edge of the arc-shaped blade block 1, so that the shredded paper can be accommodated, the shredded paper can fall conveniently during rotation, and the paper separating effect and quality are obviously improved.
