According to the PCB crushing machine, the sawteeth replace the blades to crush the PCB, the crushing effect is good, and the damage of the blades is reduced.)

1. The utility model provides a broken blade of zigzag PCB board, includes blade disc (1), its characterized in that: the side of the cutter head (1) is fixedly provided with a plurality of saw teeth (4).

2. The serrated PCB crushing blade of claim 1, wherein: a plurality of the saw teeth (4) are arranged at equal intervals.

3. The serrated PCB crushing blade of claim 1, wherein: the middle part of the cutter head (1) is provided with a plurality of leakage holes (3).

4. The serrated PCB crushing blade of claim 3, wherein: the plurality of the leakage holes (3) are distributed at equal intervals.

5. The serrated PCB crushing blade of claim 1, wherein: the middle part of the cutter head (1) is provided with a mounting hole (2).

Technical Field

The invention relates to the field of blades, in particular to a sawtooth-shaped PCB crushing blade.

Background

The blade that the PCB board used when broken all comprises handle of a knife and cutting edge basically, utilizes the cutting edge to cut the breakage to the PCB board, and the opening easily appears when the cutting edge contacts with the PCB board for a long time, makes the crushing ability decline of cutting edge, influences the normal breakage of PCB board, and the blade damage cycle is shorter.

Disclosure of Invention

The invention aims to provide a sawtooth-shaped PCB crushing blade 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 broken blade of zigzag PCB board, includes the blade disc, the avris of blade disc is fixed and is equipped with a plurality of sawtooth.

Preferably, a plurality of said serrations are arranged equidistantly.

Preferably, the middle part of the cutter head is provided with a plurality of leakage holes.

Preferably, a plurality of said orifices are equally spaced.

Preferably, the middle part of the cutter head is provided with a mounting hole.

The invention has the technical effects and advantages that:

according to the PCB crushing machine, the sawteeth replace the blades to crush the PCB, the crushing effect is good, and the damage of the blades 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. a leak hole; 4. and (4) saw teeth.

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 sawtooth-shaped PCB (printed Circuit Board) crushing blade shown in figure 1, which comprises a cutter head 1, wherein a plurality of sawteeth 4 are fixedly arranged on the side of the cutter head 1.

The plurality of teeth 4 are arranged equidistantly.

The middle part of the cutter head 1 is provided with a plurality of leakage holes 3.

A plurality of orifices 3 are distributed equidistantly.

The middle part of the cutter head 1 is provided with a mounting hole 2.

This practical theory of operation:

during the operation, utilize the sawtooth to replace the blade to carry out the breakage to the PCB board, crushing effect is good, reduces the damage of blade, easily appears the opening when avoiding the cutting edge to contact with the PCB board for a long time, makes the crushing ability decline of cutting edge, influences the normal breakage of PCB board, and the life cycle of extension blade utilizes the residue landing after the small opening 3 is convenient for broken.

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.
