Description

Continuous paint-supplying type pipeline coating rolling brush Technical Field The invention relates to the technical field of building decoration, in particular to a continuous paint-supply type pipeline coating rolling brush. Background In pipeline coating operations such as building decoration, industry are anticorrosive, traditional instrument adopts ordinary cylinder brush more, it needs constructor to dip in the paint bucket with the round brush repeatedly and dips in the coating, there is showing the defect, frequently dip in the paint and lead to construction flow to break, the operating efficiency is low, be difficult to adapt to large-scale pipeline construction demand, the coating dips in the volume unable accurate control, the initial stage coating is too much easily trickle, the coating is not enough easily to produce the roll coating vestige in the later stage, it is uneven to lead to coating thickness, influence anticorrosive and decorative effect, dip in-process coating easily drips, cause extravagant and pollution operation environment, volatile organic matter loss is unfavorable for the environmental protection simultaneously, need carry the paint bucket with oneself, it is very inconvenient when high altitude, narrow space operation, still there is the safe risk that the paint bucket knocked over. Thus, there is a great need in the industry for a pipe coating tool that provides a continuous supply of coating material and addresses the pain points described above.
