AI Technical Summary

Technical Problem

The existing lithium battery kneading device has poor dust removal performance. The negative pressure suction method cannot effectively remove the debris splashed during the kneading process, resulting in low dust removal efficiency.

Method used

A positive pressure air outlet channel is set above the kneading device, and a negative pressure dust removal pipe is set below. The positive pressure airflow is used to counteract the initial kinetic energy of the debris, and the debris is stabilized by the airflow guide ring. Combined with the design of the central needle and the airflow guide ring, a stable airflow circulation is formed to improve the dust removal effect.

Benefits of technology

It improves dust removal efficiency, reduces the power requirements of the vacuum pump, lowers equipment costs, and ensures more efficient debris removal.

Abstract

A dust removal mechanism of a battery rubbing device, comprising: a dust removal box, a positive pressure outlet channel being arranged on the top of the dust removal box and being communicated with a positive pressure source; a support shaft base being rotatable around its axis, a rubbing assembly being arranged on the support shaft base, the support shaft base being provided with a ventilation pipeline extending along its axis, and the upper part of the support shaft base being located in the dust removal box; a dust removal pipeline being communicated with the ventilation pipeline of the support shaft base; a center hole needle being arranged on the support shaft base; an airflow guide ring being arranged on the support shaft base and being located at the periphery of the center hole needle, an area formed between the airflow guide ring and the center hole needle being communicated with the ventilation pipeline; and an outlet of the positive pressure outlet channel being directed to the airflow guide ring. The utility model sets the positive pressure outlet channel above the rubbing area and sets the negative pressure dust removal pipeline below the rubbing area, blows air in the rubbing area by using the positive pressure, and the positive pressure airflow can offset the initial kinetic energy of the debris generated during rubbing, the airflow guide ring can stabilize the debris, avoids the debris from splashing, and improves the dust removal effect and the dust removal efficiency.
