Paint spraying device for local surface of cylindrical wood in building engineering

Abstract

The invention discloses a paint spraying device for a local surface of cylindrical wood in building engineering. The paint spraying device comprises a machine frame, a paint liquid tank, a stirring mechanism, a clamping mechanism, a moving and sliding block, a supporting screw rod, touch rods and reverse switches. The supporting screw rod is rotatably erected in an upper inner cavity of the machine frame, the supporting screw rod is sleeved with the moving and sliding block in a screwed connection mode, and two rectangular sliding cavities are symmetrically formed in the top of the machine frame. Adjusting screw rods are rotatably mounted in the two rectangular sliding cavities, the adjusting screw rods are sleeved with two rectangular sliding blocks correspondingly in a threaded connection mode, and supporting blocks are erected at the bottom ends of the two rectangular sliding blocks. The touch rods are arranged on the inner side walls of the two supporting blocks, the reverse switches are arranged on the left and right outer walls of the upper part of the moving and sliding block, a paint spraying seat is fixedly at the bottom end of the moving and sliding block in a suspended mode, and a plurality of paint mist nozzles are fixedly arranged at the bottom of the paint spraying seat. The paint spraying device can realize the adjustment of the distance between the two touch rods, the paint mist spraying range is controllable, and local spraying of paint mist on wood can be realized.

Description

technical field [0001] The invention relates to the field of construction wood processing, in particular to a device for spraying paint on the partial surface of cylindrical wood in construction engineering. Background technique [0002] Construction engineering refers to the engineering entity formed through the construction of various housing buildings and their ancillary facilities and the installation of supporting lines, pipelines, and equipment. The construction projects of "houses and buildings" include factories, theaters, hotels, shops, schools, hospitals and residences, etc. The new construction, reconstruction or expansion of construction projects must be done with materials and can only be realized through construction activities. Wood is the lignified tissue of plants capable of secondary growth, such as trees and shrubs. After the primary growth of these plants ends, the vascular cambium in the rhizome becomes active, developing bast outward and wood inward. ...

AI Technical Summary

Problems solved by technology

[0003] Nowadays, houses and other buildings need to use wood, and different woods play different roles. Some wood needs to be painted before being used. After the surface of the wood is polished and smooth, some are manually painted, resulting in uneven paint application. Although There are some spraying equipment in the prior art, but the spraying range is uncontrollable and inconvenient to use
