Technical Field

The invention relates to the field of blades, in particular to a wear-resistant blade for crushing a PCB (printed circuit board).

Background

The blade of the broken usefulness of common PCB board all is spiral or the formula of bending basically, and the area of contact of this kind of blade and PCB board is great, leads to the blade wearing and tearing very fast, reduces the life of blade, and blade after wearing and tearing is duller when cutting the PCB board, reduces the crushing efficiency of PCB board.

Disclosure of Invention

The invention aims to provide a wear-resistant blade for crushing a PCB (printed circuit board) so as to solve the problems in the background technology.

In order to achieve the purpose, the invention provides the following technical scheme: the utility model provides a be used for PCB board breakage to use wear-resisting blade, includes the blade disc, the mounting hole has been seted up at the middle part of blade disc, the avris of blade disc is fixed and is equipped with a plurality of blades, four trompils have been seted up on the blade disc.

Preferably, four of said openings are arranged equidistantly.

Preferably, the opening is in the shape of a sector.

Preferably, the end face of the blade is arcuate in shape.

Preferably, a plurality of said blades are equally spaced.

The invention has the technical effects and advantages that:

according to the invention, the crushing efficiency and quality of the PCB are improved through the fan-shaped blade, the wear resistance is good, and the broken residues can slide down conveniently by using the opening, so that the blockage is reduced.

Drawings

Fig. 1 is a schematic front structural view of the present invention.

In the figure: 1. a cutter head; 2. mounting holes; 3. opening a hole; 4. a blade.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The invention provides a wear-resistant blade for crushing a PCB (printed circuit board), which is shown in figure 1 and comprises a cutter head 1, wherein the middle part of the cutter head 1 is provided with a mounting hole 2, the side of the cutter head 1 is fixedly provided with a plurality of blades 4, and the cutter head 1 is provided with four openings 3.

The four openings 3 are arranged equidistantly.

The opening 3 is fan-shaped.

The end face of the blade 4 is arc-shaped.

The plurality of blades 4 are equidistantly distributed.

This practical theory of operation:

during the operation, utilize fan-shaped blade 4 to cut the PCB board broken, and fan-shaped blade 4 is less with the area of contact of PCB board, reduces the wearing and tearing of blade 4 when guaranteeing the crushing efficiency and the quality of PCB board, and the wearability is good, prolongs the life of blade 4, and broken PCB board passes through trompil 3 landing, and the residue after the breakage of being convenient for through trompil 3 slides down, reduces the jam, conveniently saves trouble, guarantees the normal breakage of blade 4.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
