Description
Technical field
The utility model relates to the spraying field, particularly relates to a kind of device that hydrojet is provided for spray gun.
Background technology
Spraying refers to the process for surface of the work by pigment or coating, is generally by spray gun, by means of pressure or centrifugal force, hydrojet is dispersed into to even and fine aerosol or particle, is applied over the coating process on coated article surface.And the devices such as spray gun; mainly to adopt gas or high pressure to take out of at a high speed by same trying to get the first word in hydrojet; carry out atomization and dispel as particle or line style, when ejection gas with coating, together spray, therefore using the device such as spray gun is to spray uniform short decorative effect.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of spray silk feeding device that can spray short silk decorative effect.
The technical solution of the utility model is as follows: a kind of skill is coated with beautiful gas piston occluding device, comprise cylinder body (1), in described cylinder body (1), be provided with piston (2), the two ends up and down of this cylinder body (1) are equipped with opening, and the lower end of this cylinder body (1) is sealed by bottom end cover (3), in described bottom end cover (3), be provided with pore (3a), an end of this pore (3a) communicates with cylinder body (1) inside, the other end and bottom end cover (3) exterior; The upper end of described cylinder body (1), by upper end cover (4) sealing, is provided with discharge opening (4a) in this upper end cover (4), an end of this discharge opening (4a) communicates with cylinder body (1) inside opening, the other end and upper end cover (4) exterior.
While adopting said apparatus to spray, piston is divided into lower upper two parts by cylinder body, in the first half of cylinder body, inject coating, then the pore on bottom end cover is connected with tracheae, use the latter half ventilation of Compressed Gas to cylinder body, pushing piston moves from bottom to top, thereby the coating that promotes to inject in cylinder body the first half sprays from the discharge opening of upper end cover, this spraying method, owing to only having coating not have gas to spray from nozzle, namely can spray short silk decorative effect in conjunction with the outside gas sprayed.After coating overflowed, the Compressed Gas pushing piston was against the cylinder body upper end, and the gas of cylinder body the latter half is intercepted by piston can't be from overflowing discharge opening.
In order to reduce the pressure of the coating of going out from discharge opening, and reduce Compressed Gas to entering the air pressure in cylinder body, described pore (4a) is " L " shape, and described discharge opening (4a) is " L " shape of turned upside down.
In order to facilitate filling paint, described upper end cover (4) center outwardly convex forms column-like projection block (7), at this column-like projection block (7) and upper end cover (4) central vertical, offer charging hole, vertical section of the lower end of this charging hole and discharge opening (4a) communicates, in this charging hole, is equiped with plug (5).Use said structure carrying out coating while filling, extract plug, get final product from pouring coating in charging hole, coating just enters into vertical section of discharge opening from charging hole, then enters in cylinder body.
Described plug (5) is for having the column structure of step surface, the stub end of this plug (5) is inserted in the charging hole of upper end cover (4), the outer fixed cap (6) that is set with of described column-like projection block (7), this fixed cap (6) has downward opening inner chamber, and the inwall of this fixed cap (6) is provided with internal thread and matches with the external screw thread on column-like projection block (7) surface, the stub end of described plug (5) is positioned at the inner chamber of fixed cap (6), the little head end of this plug (5) outwards runs through fixed cap (6), and stretching out the outer and nut (9) of fixed cap (6) is fixedly linked.The step surface of described plug is connected in the inner chamber of fixed cap, can prevent that coating extrudes plug from charging hole when discharging, and the nut be threaded at the little head end of plug can prevent that plug from dropping in cylinder body along charging hole and discharge opening.
The stub end of described plug (5) is set with sealing ring (8), and sealing circle (8) is positioned at charging hole.
Described piston (2) is connected with bolt (10) towards the center of pore (3a) one side, on this bolt (10), also be set with oil absorbent piece (11) and pad (12), described oil absorbent piece (11) is clamped by piston (2) and pad (12), and the outer peripheral face of this oil absorbent piece (11) contacts with cylinder body (1) inwall.In use, because hydrojet does not contain lubricating oil, the not lubricated easily wearing and tearing of the permanent motion of piston, by the upper lubricating oil of oil absorbent piece absorption, piston, when moving up and down, drives oil absorbent piece and moves up and down, and oil absorbent piece rubs mutually with inboard wall of cylinder block, the lubricating oil adhered on oil absorbent piece just can be attached on inboard wall of cylinder block, thus lube pistons.
Can't oil suction in order to prevent that oil absorbent piece from being pushed too much by bolt, described oil absorbent piece (11) is sleeved on bolt (10) by limiting gasket (13).
Beneficial effect: the utility model can adopt gas that the coating in cylinder body is pressed into to the place ahead on spray gun rifle mouth, when flowing out, liquid material can be blown out the thread effect of irregular fineness by the air-flow that outside air gun sprays downwards, not only have convenient and swiftly, also have the characteristics such as spray pressure is stable, coating quality is high, low cost of manufacture.
