Abstract
The invention discloses a double-funnel type medium-pressure smoke discharging device for a laser engraving (cutting) machine, which comprises a double-funnel type fan cover with an air hole on the periphery, a dual-horn mouth air suction nozzle, a dual plugging air door, and a splayed movable cover plate. The lower end of the dual-horn mouth air suction nozzle which is positioned in the center of the whole fan cover is connected with an exhaust duct, and the other end of the exhaust duct is connected with a powerful exhaust fan. The powerful negative pressure generated by the fan is guided through the exhaust duct by the dual-horn mouth air suction nozzle; and strong negative pressure airflow is generated in the middle space of the double-funnel fan cover so as to extend towards the periphery to the edge of the fan cover, so that toxic and harmful flue gas generated during laser engraving (cutting) processing is rapidly and efficiently discharged. The double-funnel type medium-pressure smoke discharging device for the laser engraving (cutting) machine also has the advantage of convenient installation, use and maintenance.
Description
[technical field]
The present invention is a kind of fume extractor that is applicable to laser engraving (cutting) machine field.
[technical background]
The basic principle of laser engraving (cutting) machine is exactly to make the Workpiece shaping that is seated on the work top by the high energy laser beam calcination.Follow laser processing procedure can produce a large amount of poisonous and harmful flue gases, not only contaminated environment but also corrode machine.The general composition of laser machine smoke evacuation system is: fume extractor one smoke discharging pipe---the air exhauster of work top (workpiece) machine intimate, for reducing the influence of blower fan vibrations to operating accuracy, blower fan is all fixed away from machine.As seen, decision laser machine smoke evacuation system effect quality mainly is whether the fume extractor design of machine intimate is reasonable.When guaranteeing efficient smoke evacuation, also should take into full account the collection of clearing up laying dust and tiny workpiece and tiny waste material how easily.And the fume extractor of prior art does not address these problems well.
[summary of the invention]
The technical problem that institute of the present invention desire solves provides good, the tiny workpiece of a kind of smoke discharging effect and garbage collection is cleared up pressure type fume extractor in laser engraving (cutting) the machine double-funnel convenient, that unitary construction is simple, cleaning is easy.
The technical solution used in the present invention is: press principle in the utilization, adopt by double-funnel fan housing, double horn mouth air draught mouth, splayed configuration removable cover, drawer type charging conduit, air door plate and form fume extractor in laser engraving (cutting) machine.This device places laser machine worktable face below, and double horn mouth air draught mouth is positioned at whole fan housing centre, and air draught mouth lower end connects powerful blower fan by smoke discharging pipe and forms smoke evacuation system.
The technique effect that the present invention reached is: when machine was not worked, whole device was the upper end open type, can be used for room ventilation.During machine works, the double-funnel fan housing forms certain confined space with the big workpiece that is seated on the machine works table top, powerful negative pressure by the blower fan generation, lead through double horn mouth air draught mouth by exhaust duct, two funnel fan housing central space produce extremely strong negative-pressure air-flow and to around extend to the fan housing edge, the flue gas that produces during to Laser Processing can be fast, fully discharge, even closing machine intrinsic protection cover can not guaranteed free from extraneous odour yet.Thisly can open working method be convenient to the operating staff and observe the laser head working condition, the effectively generation of accident prevention.The use of air door plate realizes that selectivity improves the efficient smoke discharging effect that smallclothes add man-hour.Funnel type fan housing, top, inlet scoop splayed configuration removable cover prevent that effectively tiny workpiece and waste material are inhaled into tuyere.The embedded screen pack of alternative interpolation in the tuyere chamber is so that realize improving to greatest extent the ventilation efficiency of blower fan.Fan housing bottom design one drawer type charging conduit, convenient tiny workpiece and garbage collection and very easy cleaning.This device have smoke evacuation fully, simple structure, be easy to make, with low cost, working service advantage extremely easily, greatly improved laser engraving (cutting) machine operating efficiency, improved work situation.

[specific embodiment]
1, fume extractor of the present invention adopts the making of 0.9-1.2MM iron plate, and concrete preparation method sees also figure one to figure seven.
2, this device is placed on laser engraving (cutting) the machine worktable face 8 below laminate supports 13 (seeing also figure eight).Double horn mouth air draught mouth 2 modularization makings, taking-up snaps in carriage 12 after connecting exhaust duct 6, and exhaust duct 6 other ends connect centrifugal blower 7, and air draught mouth top is placed splayed configuration removable cover 3 and is promptly finished smoke evacuation system installation (the embedded filter screen 11 optional dresses in tuyere chamber).
3, large format workpiece 9 adds man-hour, opens horn mouth both sides air door plate 5 (A/B), opens centrifugal blower 7 and gets final product operate as normal.During laser engraving, flue gas mainly concentrates on workpiece 9 tops, and the powerful vacuum flow that fresh air inlet 13 (seeing also figure four) produces around the fan housing can effectively be got rid of flue gas, and this moment is better as 14 smoke discharging effects of the protected enclosure of closing machine own.Flue gas mainly concentrates on workpiece 9 belows during cutting, and in the both sides of two funnel fan housings 1 central space, the strong negative-pressure air-flow that leads through double horn mouth air draught mouth 2 is got rid of flue gas fast.In the actual production, good smoke discharging effect allows the machine protected enclosure 14 can open work, more helps the operating staff and observes the laser head working condition, and effectively accident prevention takes place.Processing can be placed on workpiece the fan housing middle part during than the workpiece of large format, and the negative-pressure air-flow around it is enough to get rid of flue gas quick and completely.And the small breadth workpiece adds man-hour in batches, also workpiece can be placed on side leakage bucket top, closes opposite side horn mouth air door plate, has more guaranteed efficient smoke evacuation.
4, tiny workpiece and the odds and ends 10 of following negative-pressure air-flow to come off in the process, middle part are by splayed configuration removable cover 3, drop down onto the drawer type stock chest by the hopper walls free skating all around.It is also very convenient both to put and end to waste, put in order cleaning.
5, during the processing rigid material, need not to use filter screen in the whole air channel, remove splayed configuration removable cover 3, can take out the embedded filter screen 11 in tuyere chamber, because of tiny workpiece and odds and ends can not enter the air channel, so can realize smoke exhaust efficiency to greatest extent; And processing is removed splayed configuration removable cover 3 during light material, inserts the embedded filter screen 11 in tuyere chamber and gets final product operate as normal.Accept or reject and comply with one's wishes, the filter screen cleaning is ery easy especially.
In a word, pressure type fume extractor in laser engraving of the present invention (cutting) the machine double-funnel, simple and reliable for structure, it is quick and complete to discharge fume, and working service is very convenient.
