Painting brush coating and roller coating integrated device

Abstract

The invention provides a painting brush coating and roller coating integrated device. The painting brush coating and roller coating integrated device combines the advantages of the effects of brush coating and no dead corner with the advantage of coating efficiency of roller coating, so that while the coating quality is ensured, construction efficiency is improved, and coating period is shortened. The painting brush coating and roller coating integrated device is characterized by comprising a roller head, a brush head and a gravity constant device, the working position of the brush head is located above the roller head, the axial direction of the brush head is parallel with the axial direction of the roller head, the roller head comprises a roller core and a roller which is installed on the roller core in a freely rotary mode, the gravity constant device is connected with the brush head through a lever, the connection line of the gravity center of the gravity constant device and the supporting point of the lever deflects in the vertical direction, and the brush head and the gravity constant device are located on the same side of the lever, so that the gravity of the gravity constant device plays a role in hampering the brush head to enable the angle between the brush head and a working face to be constant.

Description

technical field [0001] The present invention relates to application devices for applying paint. Background technique [0002] In decoration, coatings are widely used. The commonly used construction methods are roller coating and brush coating. In terms of coating effect, knurling is inevitable and the degree of fineness is not high when rolling coating. However, brush coating has no obvious construction traces of roller coating, and the effect is relatively smooth and delicate. From the perspective of the painted surface, the brush can meet almost all the operations of the painted surface, while the roller is only suitable for flat surface painting, and due to the limitation of the tool, there will be a construction dead angle on the edge of the vertical surface, that is, there will be incomplete painting. to the part.

Problems solved by technology

[0003] However, in terms of coating efficiency, brushing cannot be compared with roller coating. Taking the medium-long hair roller commonly used in architectural decoration as an example, dipping the paint once can paint 1-2M 2 Even more, while the brush paints 1M 2 , at least a dozen or even dozens of times of dipping, so the work efficiency is low and the labor intensity is high

[0004] In the actual construction work, it is often adopted that one construction worker rolls the paint on the front with a roller, and the other builds the back with a brush to sweep evenly, and repaints the dead corners of the construction by roller coating. Such a traditional construction method is relatively expensive. High labor costs
