Abstract
The utility model discloses a double-hopper-type medium-pressure smoke evacuator of a laser engraving cutting machine, which comprises a double-hopper-type fan cover with the periphery equipped with air holes, a double-horn-mouth induced-draft nozzle, a double-pulling-and-inserting-type air door and a splay movable cover plate. The lower end of the double-horn-mouth induced-draft nozzle located on the center portion of the total fan cover is connected with an exhaust duct, and the other end of the exhaust duct is connected with a strong fan. Strong negative pressure generated by the fan passes through the exhaust duct, is guided by the double-horn-mouth induced-draft nozzle, forms negative pressure air flow in space of the middle portion of the double-hopper fan cover and extends to the edge of the fan cover in all directions, and toxic and harmful smoke generated during processing of the laser engraving cutting machine can be exhausted fast and high-efficiently in any work modes. The bottom portion of the double-hopper-type fan cover is respectively equipped with drawer-type charging conduits, mouths of hoppers are smaller than those of drawers, and then dropped small workpieces and scattered waste materials can be collected completely and cleaned conveniently. The double-hopper-type medium-pressure smoke evacuator further has the advantages of extremely simple and convenient mounting, using 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: work top (the workpiece)---fume extractor of machine intimate---smoke discharging pipe---air exhauster.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 the laser engraving cutting 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 and form fume extractor in the laser engraving cutting machine by double-funnel fan housing, double horn mouth air draught mouth, splayed configuration removable cover, drawer type charging conduit, air door plate.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 became 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 fan housing edge fresh air inlet, 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 filter screen of alternative interpolation in the tuyere chamber is so that realize improving to greatest extent the ventilation efficiency of blower fan.The fan housing bottom design has drawer type charging conduit and bell mouth less than drawer, and tiny workpiece and odds and ends that cutting comes off are dropped into drawer along the hopper walls free skating, and blanking is collected fully, cleaning is convenient.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 Fig. 1 to Fig. 7.
2, this device is placed on the laser engraving saw working bench face 8 below laminate supports 13 (seeing also Fig. 8).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 15 (seeing also Fig. 4) 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, the middle part drops down onto the drawer type stock chest by the hopper walls free skating all around by splayed configuration removable cover 3.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 the laser engraving cutting machine double-funnel of the present invention, simple and reliable for structure, it is quick and complete to discharge fume, and working service is very convenient.
