Detailed Description

In order to further explain the technical scheme of the utility model, the utility model is explained in detail by specific examples.

Referring to fig. 1 and 2, the utility model discloses a powder dust collection mechanism, which is provided with a dust collection cover 1 and a dust collection branch pipe 2 connected with negative pressure gas, wherein the dust collection cover 1 is provided with a dust collection opening 11; and a discharge hole 31 of the discharging mechanism 3 is positioned in the dust hood 1.

When the powder dust collection mechanism of the utility model is used for discharging and collecting dust, electrode powder is discharged downwards from the discharge hole 31; the dust collection branch pipe 2 is connected with a negative pressure fan, the dust collection branch pipe 2 is communicated with negative pressure gas, dust generated during electrode powder blanking is collected by the dust collection branch pipe 2, blanking is performed simultaneously, time is saved, and production efficiency is improved; the discharge hole 31 extends into the dust hood 1, so that a blanking and dust collection integrated structure is realized, dust collection, recycling and reutilization can be comprehensively carried out on powder generated during blanking, and the dust collection effect is good; the dust collection device is not required to be additionally and independently arranged, and the structure is simple and the cost is low; according to the utility model, dust is synchronously sucked in the blanking process, and is directly sucked into the blanking mechanism 3, so that dust flying is avoided, the health of workers is ensured, and the dust is directly recycled, so that raw material waste is avoided, and the dust-free blanking machine is more environment-friendly.
