Description
Technical field
The present invention relates to guitar grinding technology field, more particularly, relate to a kind of guitar polishing dust removal system for workshop.
Background technology
In order to ensure to produce the qualified product obtained, need in guitar production process through processes such as corase grind, fine grinding, polishings, guitar is also divided into body and neck two parts, the body of guitar and the polishing work of neck are first separately polishings, assembling rear continuation polishing, in this multiple sanding and polishing process, the sanding and polishing machine used is all different.And be no matter in which step process for sanding process, all a large amount of wood powders can be produced, if these wood powders are sucked by the direct labor in workshop, healthyly great harm will be caused to it; For wood processing workshop, larger hazards are disaster hidden-trouble, so must have perfect fire prevention measure in factory, and the dust in wood processing workshop belongs to one of combustible dust, after reaching finite concentration, run into naked light or spark is very easily blasted, abnormally dangerous.Along with the development of economy and improving constantly of living standards of the people, the working environment of people obtains and improves significantly, improves workshop condition, reduces employee's occupational disease, reaches national requirements for environmental protection, become enterprise's top priority.
But for guitar production plant, dedusting work has a difficult problem for two aspects, one is that the mechanical type that guitar sanding and polishing uses is various, namely produce dirt mode, wood chip dust dispersal direction is various, such as some grinding machine produces larger wood pellet, seat particle is in some generation, some is along upper tangential direction, some is along the existing direction of incision, again because some is more heavier than general dust granule in wood powder, so dust-precipitating system needs all there is good pick-up performance for different product dirt machinery; Two is that wood powder particle size range is wider, and dust concentration is higher, and general dust pelletizing system cannot meet wood pellet dust removal requirement.
Through retrieval, Chinese Patent Application No.: 201310305437.1, the applying date: on July 19th, 2013, invention and created name is: a kind of dust exhaust apparatus, this technical scheme comprises base, base is provided with motor, described motor output end is fixedly connected on casing side by cover cylinder, at casing upper end open place by the second bolt connection outlet lid, the output shaft of motor stretches in casing, and impeller is fixedly connected with on motor output shaft, described casing opposite side is fixed with sweep-up pipe by the first bolt.Although the dust exhaust apparatus of this invention can according to the actual conditions of factory floor, control of dust is carried out to the place that workshop dust is more from flexible arrangement to a certain extent, but also because dust exhaust apparatus is single, in the face of between guitar grinding machine, the specification of different grinding machine can not well meet the requirements, and because wood chip is more heavier than general dust granule, if concrete dust granules source, inlet scoop is comparatively far away, control of dust requirement can not be met far away by wind-force.
