Abstract
The utility model belongs to metal surface coating treatment process field relates to an intraductal wall application spray gun, comprises handle and spray tube, and the spray tube includes outer tube and inner tube, and the inner tube is the coating passageway, and along inner tube direction blowout, the gap is the compressed air passageway between outer tube and the inner tube, and the nozzle through special design is from one side towards the coating blowout, obtains the small-angle sector fog type that coating sprayed. The utility model discloses can prevent the jam of coating in the spray tube pipe wall and wash inconveniently, the spraying fog type that obtains has effectively improved the spraying effect.
Description
Technical field
The utility model belongs to coating metal surfaces treatment process field, is specifically related to a kind of inside pipe wall application spray gun.
Background technology
In coating metal surfaces treatment process field, often run into the situation that the metal device inwall need carry out application, as laser printer roller bearing etc., interior finishing is had higher requirements.Existing proboscis inwall spray gun, because making, the structural design of proboscis spray gun waits that the coating of constructing mixes in the proboscis wall of long spray gun with compressed air, in 5cm place, distance nozzle place waits to construct the coating helicla flute, quicken, to ejection all around, produce the circle spraying of full round angle from nozzle.Said method usually causes the coating of waiting to construct to stop up in the helicla flute inner accumulated of nozzle long tube, so that can't reach the mist type disappearance of spraying mist type or certain direction of expectation, finally causes portion's product of institute's application bad.The problems referred to above become problem points to be solved in the utility model.
Summary of the invention
The purpose of this utility model is to provide a kind of inside pipe wall application spray gun, design novel lance tube structure, change wait to construct coating and the situation that compressed air mixes in proboscis spray gun tube wall, realize rational coating mist type, thereby improve the inner coating process effect of pipe.
The technical solution of the utility model is: a kind of inside pipe wall application spray gun, constitute by handle and jet pipe, and from handle input coating and compressed air, jet pipe adopts ad hoc structure to obtain the mist type that coating sprays.
Described handle below is provided with the coating inlet, and the rear portion is provided with the compressed air inlet.
Described jet pipe is the long tube shape, and front end is provided with tube head.
Described jet pipe comprises outer tube and interior pipe, is hollow, and interior pipe box is in outer tube, and inner pipe passway is communicated with the coating inlet of handle, and the passage that the slit constitutes between outer tube and the interior pipe is communicated with the compressed air inlet of handle.
The tube head of described jet pipe is provided with paint spray nozzle and two nozzles of compressed-air atomizer, paint spray nozzle is communicated with inner pipe passway, it is consistent with inner pipe passway to spray direction, compressed-air atomizer is located on the projection of shower nozzle one side, and the channel connection that the slit constitutes between outer tube and the interior pipe, jet direction is vertical with channel direction.
Adopt the jet pipe of said structure, coating is walked different passages with compressed air, during use, the coating of waiting to construct sprays forward by paint spray nozzle, and compressed air sprays towards coating from a side by compressed-air atomizer, and coating and compressed air meet outside nozzle, because compressed air is in the rapid expansion at nozzle place, produce an eccentric air flue, coating is sprayed away to the side, obtain low-angle covering of the fan mist type at a certain direction.During operation,, can finish whole inside pipe wall spraying by corollary equipment rotating band spraying part.Such nozzle structure had both been avoided the obstruction of coating in spray gun, can obtain required mist type again.
The beneficial effects of the utility model are that the inside pipe wall application spray gun through after the repacking not only can obtain required mist type, improves spraying effect, can also prevent obstruction and the cleaning inconvenience of coating in the proboscis tube wall.
Description of drawings
Fig. 1 is a structural representation of the present utility model.Wherein, 1 is handle, and 2 are the coating inlet, and 3 is the compressed air inlet, and 4 is jet pipe, and 5 is nozzle head.
Fig. 2 is the section enlarged diagram of the utility model proboscis jet pipe front end.Wherein, 6 is the jet pipe outer tube, and 7 is pipe in the jet pipe, and 8 is paint spray nozzle, and 9 is compressed-air atomizer.
Schematic diagram when Fig. 3 implements for the utility model.Wherein, 4 is jet pipe, and 8 is the coating spout, and 9 is the compressed air spout, the 10 mist types that produce for when operation.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described further:
As shown in Figure 1, a kind of inside pipe wall application spray gun is made of handle (1) and jet pipe (4), and described handle (1) below is provided with coating inlet (2), and the rear portion is provided with compressed air inlet (3), and described jet pipe (4) is the long tube shape, and front end is provided with tube head (5).
As shown in Figure 2, described jet pipe (4) comprises outer tube (6) and interior pipe (7), be hollow, interior pipe (7) is enclosed within the outer tube (6), and inner pipe passway is the coating passage, is communicated with paint spray nozzle (8), it is consistent with inner pipe passway to spray direction, the slit is a compressed air channel between outer tube and the interior pipe, is communicated with compressed-air atomizer (9) on being located at shower nozzle one lateral process, and jet direction is vertical with channel direction.
As shown in Figure 2, when implementing the utility model, the coating of waiting to construct sprays forward by paint spray nozzle, compressed air sprays towards coating from a side by compressed-air atomizer, coating and compressed air meet outside nozzle, because compressed air produces an eccentric air flue in the rapid expansion at nozzle place, coating is sprayed away to the side, obtain low-angle covering of the fan mist type at a certain direction.By corollary equipment rotating band spraying part, can finish whole inside pipe wall spraying.
