Combined type woodworking engraving machine of multi-station dust removing device

Abstract

The invention discloses a combined type woodworking engraving machine of a multi-station dust removing device. The combined type woodworking engraving machine comprises a machine platform for loading an object to be engraved and a rack which spans across the machine platform, and further comprises a dust removing mechanism; the dust removing mechanism comprises a main body; a negative-pressure general pipe and sealed air cylinders are arranged at the top of the main body; a plurality of negative-pressure branched pipes are arranged at the bottom of the dust removing mechanism; the positions of the sealed air cylinders and the negative-pressure branched pipes correspond to the positions of engraving machine main shafts; a sealing plug is connected with the tail end of a piston rod of one sealed air cylinder; the shape of the sealing plug is adaptive to the shapes of inner walls of the negative-pressure branched pipes; when the piston rod of the sealed air cylinder moves toward one negative-pressure branched pipe, an outer wall of the sealing plug is clung to the inner wall of the negative-pressure branched pipe. When a certain engraving machine main shaft does not work, an air cylinder works to block the corresponding negative-pressure branched pipe through the sealing plug; meanwhile, a negative-pressure gas value is reduced by the system and dust collection work of other stations can still be realized, so that the cost is saved and the combined type woodworking engraving machine is easy to repair and manage.

Description

technical field [0001] The invention relates to the field of numerical control machine tool processing equipment, in particular to a woodworking engraving machine with a combined multi-station dust removal device. Background technique [0002] Engraving machine is a general mechanical equipment widely used in wood industry, advertising industry, handicraft industry, mold industry, construction industry, printing and packaging industry, decoration industry, it can carve woodworking board, density board, acrylic organic board, PVC board, hibiscus Board, two-color board, marble, jade, fireproof board, rubber board, glass and other materials. [0003] The multiple engraving knives and their supporting mechanisms of the existing multi-head engraving machine are generally fixed as a whole, and the same signal is used for overall control. Multiple engraving knives can only move up and down as a whole, and each engraving knife cannot be controlled and calibrated independently. When...

Problems solved by technology

[0003] The multiple engraving knives and their supporting mechanisms of the existing multi-head engraving machine are generally fixed as a whole, and the same signal is used for overall control. Multiple engraving knives can only move up and down as a whole, and each engraving knife cannot be controlled and calibrated independently. When the workpiece material corresponding to each engraving knife is slightly different in thickness and hardness, because the engraving machine cannot individually control each engraving knife, the engraving accuracy is reduced

[0004] The existing multi-head engraving machine is distributed on an aluminum plate. Each engraving machine spindle is independently controlled by the control system for engraving. During the engraving process, a lot of dust and impurities will be generated, which need to be sucked away by the negative pressure system. Sometimes a certain engraving machine The main shaft of the machine does not work, but at this time the negative pressure system still sucks air at this station, resulting in ineffective loss and increased cost
