The specific embodiment
As shown in Figure 1, described multi-functional spray gun for paint along the gas channel in the rifle body, is disposed with material pin adjusting device 3, air valve 9, amplitude regulation arrangement 2, feed mode conversion equipment (15-17), nozzle 11, divides compression ring 26 and stream cap 6; They and rifle body 1 forms one and begins a gas passage till the stream cap 6 from inlet suction port 8;
Material pin adjusting device 3 be positioned at rifle body 1 the rear end, be provided with air valve 9 and material pin 10 in the material pin adjusting device 3, material pin 10 withstands on the front inner wall of nozzle 11, forms the switch valve of a coating; The middle part of material pin is provided with material pin self sealss part 12; Nozzle 11 is communicated with coating kettle 4 by passage 13, has formed the paint path 27 of a sealing;
As shown in Figure 2, side at rifle body 1 front end is provided with the feed conversion equipment, the feed conversion equipment comprises adjusting knob 15, adjustment seat 16, regulating valve stem 17, pressure sending type air admission hole 18 and tonifying Qi hole 21, adjustment seat 16 is fixed on the rifle body 1, adjustment seat 16 is provided with the passage 25 that is in communication with the outside, adjusting knob 15 is connected with regulating valve stem 17, when rotating adjusting knob 15, regulating valve stem 17 can cut out and open pressure sending type air admission hole 18, when opening pressure sending type air admission hole 18, be communicated with coating kettle 4 by tonifying Qi hole 21 during pressure sending type air admission hole 18, thereby realize the pressure sending type feeding; When closing pressure sending type air admission hole 18, coating kettle 4 is in communication with the outside by the passage 25 on tonifying Qi hole 21 and the adjustment seat 16, thereby realizes the hydrocone type feed.
As shown in Figure 3, described stream cap 6 comprises three kinds of forms, and the stream cap 22 of two jiaos of ears of one band is high pressure stream cap, and the stream cap 24 of the stream cap 23 of its two bands straight trough and its three bands circular port is low-pressure stream cap.When with angle ear stream cap 22, secondary streams 19 is from the ejection of angle ear, and amplitude of accommodation adjusting device can be closed and open auxiliary air-flow aperture 5, by the size of control secondary streams, can adjust the spraying swath shape (from the circle to the oblong) of coating; When with straight trough stream cap 23 and circular hole stream cap 24, primary air 7 and secondary streams 19 directly are mixed into one the tunnel and from nozzle with flow the gap of cap and spray behind undue compression ring 26.
Use principle is: when spray gun normally uses, after compressed air enters the rifle body from inlet suction port, earlier in air valve enters amplitude regulation arrangement, amplitude regulation arrangement can be divided into air-flow major and minor two-way air-flow, when with angle ear stream cap, at this moment primary air ejection ejection from the gap of nozzle and stream cap will produce medium sucking-offs such as suction will paint; Secondary streams is ejections from two jiaos of ears, will paint atomizing, and form uniform spraying swath, can regulate the shape (from the circle to the oblong) of spraying swath by amplitude of accommodation adjusting device; Simultaneously also can make a part of compressed air enter the coating kettle, carry out the pressure sending type feed to spray gun for paint, thereby change normal hydrocone type feed mode by the adjusting knob on the feeding adjusting device; Can use different spray pressures and feed pressure according to spraying medium and the different of spraying requirement; When the stream cap 24 of the stream cap that uses straight trough and its three bands circular port, be merged into one the tunnel between the gas collection that the major-minor air-flow is directly formed and spray then before stream cap and nozzle, adjusting knob must be opened employing force feed feed mode when normally using.Regulate the adjusting knob of material pin adjusting device rear end, can control the stroke of material pin, and then the flow size of control coating; Material pin self sealss part can prevent that coating from spilling and preventing that extraneous air from entering into coating.
