Abstract
This utility model provides the wiper mechanism of a kind of polyureas spray-painting gun, belongs to spray Polyurea Elastomer Technology field.It is made up of cylinder projection, high air pressure passages, abluent passage, check valve on pressure-air connector, abluent connector, gun body.The supplies cleaner structure of this utility model design, owing to being mounted with check valve, makes material in material mixed process can not enter in wiper mechanism when spray gun spraying operation；Design elder generation by abluent cleaning spray gun again by pressure-air cleaning spray gun, during cleaning spray gun, open material abluent valve, under pressure, abluent enters spray gun and is removed by the material in spray gun, after removing, closes material abluent valve, open pressure-air access switch simultaneously, the abluent in gun body is purged out gun body.It is more thorough, quick that the supplies cleaner structure of this utility model design makes spray gun clean, and improves the life-span of spray gun.
Description
Technical field
This utility model belongs to spray Polyurea Elastomer Technology field, relates to the wiper mechanism of a kind of polyureas spray-painting gun.
Background technology
Traditional polyureas spraying is that carbimide component exists with amide components (expecting to be called for short with A material, B individually below)
Produce impingement mix in polyureas gun body, realize the mixing of two kinds of components in the moment clashed into, occur chemical reaction to generate one
Elastomeric material, so spray gun is the Core equipment of polyureas spraying elastomeric technology.Nowadays clean polyureas spray-painting gun generally to adopt
By machinery automatically cleaning and pressure-air two kinds of methods of cleaning, pressure-air cleaning is after spray gun is shut down, will spray with pressure-air
Polyurea materials in rifle purges out gun body, and this kind of method is cleaned not thorough in causing gun body, polyurea materials has certain
Residual.
Summary of the invention
The purpose of this utility model is to provide the wiper mechanism of a kind of polyureas spray-painting gun, solves the problems referred to above.
The technical solution adopted in the utility model and operation principle be: when spray gun spraying operation, by the peace of check valve
Dress so that in material mixed process, material can not enter in wiper mechanism.After carrying out a spraying operation, unclamp trigger,
Material feeding valve closing, opens material abluent valve simultaneously, and under pressure, abluent enters spray gun by spray gun
Material is removed, and after removing, closes material abluent valve, opens pressure-air access switch, by gun body simultaneously
Abluent purges out gun body.
The technical scheme that the utility model proposes provides the benefit that:
First, more excellent devises supplies cleaner structure, uses and first uses abluent cleaning spray gun, then purges with pressure-air
Spray gun so that spray gun cleans more thorough, quick, improves the life-span of spray gun；Second, when designing the wiper mechanism of spray gun,
Spray gun performance, operating characteristics and processing and manufacturing are considered so that the wiper mechanism of spray gun is reasonable in design, easy and simple to handle, just
In processing.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings this utility model is described in further detail:
Fig. 1 is spray gun general assembly drawing front view of the present utility model；
Fig. 2 is the spray gun general assembly drawing of the present utility model sectional view at supplies cleaner structure；
In figure, 1 is pressure-air connector；2 is abluent connector；3 is that on gun body, cylinder is protruding；4 high pressure are empty
Gas passage；5 is abluent passage；6 is check valve；7 is check valve back-moving spring；8 is check valve baffle plate；
Detailed description of the invention
Below in conjunction with the accompanying drawings, the technical scheme in this utility model embodiment is clearly fully described by.
As shown in Figure 1, 2, after spray gun stops operation, material can accumulate in mixing chamber and material channel, if not in time
Cleaning, then can blocking channel, destroy spray gun.On gun body, design coordinates with pressure-air connector 1 and abluent connector 2
Screwed hole, accordingly outside pressure-air connector 1 with abluent connector 2 design cooperate with it installation identical greatly
Little helicitic texture.Gun body outside high pressure air channel inlet and abluent feeder connection respectively with pressure-air connector
1, designing two cylinder projections 3, beneficially connector and gun body at abluent connector 2 cooperation coordinates installation tightr.
Pressure-air connector 1 and abluent connector 2 all closely cooperate with supply pipe, and all use threaded joining with gun body
Close and install, improve sealing effectiveness.
As in figure 2 it is shown, after pressure-air connector 1 and abluent connector 2 all coordinate with gun body and install, high pressure is empty
Gas passage 4 and abluent passage 5 design respectively in pressure-air connector 1 and abluent connector 2, and internal diameter is 5mm, high
Pressure air connection piece 1 and abluent connector 2 are with material connector level in a distance, it is ensured that installation connecting element and confession
Should not interfere during pipe.
Further, because high air pressure passages 4 and abluent passage 5 design respectively enters Channel front end at material,
During for preventing spray gun spraying from working, in material reflux to supplies cleaner structure, high air pressure passages 4 and abluent passage 5 export
End design and installation check valve 6, gun body groove has cylinder boss, check valve 6 to put thereon at mixing chamber, pressure-air
Connector 1 and abluent connector 2 all use with gun body threaded cooperation to install and are fastened in flushing channel by check valve.
During spray gun work, polyurea materials is blocked outside abluent enters passage by check valve baffle plate 8 completely.When cleaning spray gun, open-minded
Material abluent pressure source, check valve baffle plate 8 makes one-way valve spring 7 compress under pressure, 5 dozens, material abluent passage
Opening, material abluent enters spray gun, Rapid Cleaning spray gun, after having cleaned, closes material abluent valve, check valve baffle plate 8
Under back-moving spring 7 acts on, it is returned to initial position, material abluent passage is cut off again.Open pressure-air to enter simultaneously
Switch, the abluent in gun body is purged out gun body by pressure-air, closes pressure-air valve, check valve after having purged
High air pressure passages 4 is cut off by 6.
Further, this utility model is applicable not only to the spray gun of polyurea materials mixing, and the cleaning of remaining spray-painting gun is equal
It is suitable for.
Although preferred embodiment of the present utility model being described above in association with accompanying drawing, but this utility model being not limited to
Above-mentioned detailed description of the invention, above-mentioned detailed description of the invention is only exemplary rather than determinate, the common skill of this area
Art personnel, under enlightenment of the present utility model, on the premise of objective of the present utility model and claim, can do
Represent, within such conversion each falls within protection domain of the present utility model as going out multiple types.
