Description

A putty spraying machine

technical field

The utility model relates to the field of paint spraying equipment, in particular to a putty spraying machine.

Background technique

The putty spraying machine is a small machine for stirring, pumping and spraying high-quality putty powder. It is one of the spraying machines. It mainly sprays various decorative putty produced at home and abroad. Atomization effect, suitable for house protection, painting, priming, etc.

In the Chinese utility model patent whose publication number is CN204220341U, a new type of real stone paint/putty spraying machine is disclosed, which includes a pressure tank and a spray gun connected with the pressure tank. The upper cover of the pressure tank is connected with the pressure tank by means of an inner buckle. The spray gun includes a spray gun body. The lower side of the spray gun body is respectively provided with a paint channel and an air pressure channel. The opening of the spray gun body is located on one side of the paint channel. An atomizing material spraying mechanism is provided, and a communication cavity connecting the paint channel and the air pressure channel is provided in the spray gun body, and a valve stem control mechanism is arranged in the communication cavity to control the communication between the air pressure channel and the atomizing material spraying mechanism.

The above-mentioned patents increase the capacity of the storage tank and overcome the defect of poor circulation of the paint caused by the gravity of the traditional storage tank. However, the nozzles of the above-mentioned putty spraying machines are sharp, and when the wall is sprayed, the pressure at the center of the paint sprayed by the nozzle is different from that at the edge, resulting in unevenness during the spraying process, and when spraying, there is a gap between the nozzle and the wall. At a certain interval, the sprayed paint will scatter, which will also lead to uneven spraying.

Utility model content

Aiming at the existing technical problems, the utility model provides a putty spraying machine. By setting the first nozzle in a flat shape, when the first nozzle sprays the paint, the pressure at the center and the edge is the same, and the sprayed paint is more uniform. Set up a protective cover to avoid scattering caused by feeding.

In order to achieve the above object, the utility model provides the following technical solutions:

A putty spraying machine, comprising a spraying machine body, the spraying machine body is connected with a feeding pipe, the end of the feeding pipe away from the spraying machine body is connected with a spray gun, and the spraying gun is connected with an extension rod, and the extension rod is away from One end of the spray gun is connected with a first nozzle, the first nozzle is set in a flat shape, the first nozzle is screwed to the extension rod, and a flat protective cover is arranged outside the first nozzle.

By adopting the above-mentioned technical scheme, since the pressure of the center of the nozzle is different from that of the periphery when spraying with a general sharp nozzle, the sprayed paint is uneven, resulting in uneven sprayed paint on the wall, which requires repeated spraying , by setting the nozzles in a flat shape, the sprayed paint is more uniform, and a protective cover is set around the first nozzle, and the protective cover plays the role of converging and blocking materials to prevent the paint from flying out.

Further, the interior of the extension rod is hollow, the muzzle of the spray gun communicates with the extension rod, and the end of the extension rod away from the spray gun communicates with the first nozzle.

By adopting the above technical solution, by setting the extension rod to be hollow, the paint flows out from the spray gun and sprays directly through the extension rod and the first nozzle, without the need for an additional feeding pipe, and is more convenient to use.

Further, one side of the bottom end of the protective cover is provided with several rollers, and the rollers are arranged side by side along the length direction of the protective cover.

By adopting the above-mentioned technical scheme and setting rollers, when spraying paint, the flat first nozzle can be pasted on the wall through the rollers, and then the first nozzle can be pulled to achieve the effect of spraying while walking. The first nozzle and the wall The distance between the objects is fixed, as long as the pulling speed of the first nozzle is controlled to make the speed uniform, that is, the sprayed paint is more uniform.

Further, the protective cover is further provided with a baffle between the roller and the first nozzle, and the baffle is fixedly arranged with the protective cover and its height is higher than the diameter of the roller.

By adopting the above technical solution, during the use of the putty spraying machine, the protective cover is closely attached to the wall through the rollers. When the extension rod is manually pulled, an acute angle is formed between the extension rod and the wall, and the paint sprayed from the first nozzle It will be sprayed on the roller, causing damage to the rotating shaft of the roller. By setting the baffle, the baffle is blocked between the roller and the first nozzle, and the paint will not be sprayed on the roller.

Further, a scraper is provided on the side of the bottom end of the protective cover away from the rollers, and the scraper is arranged along the length direction of the protective cover.

By adopting the above-mentioned technical solution, pulling the extension rod, the extension rod is tilted on the wall, and the first nozzle sprays the paint for spraying. Since the paint may be left in strands after being applied to the wall, by setting the scraper, dragging During the moving process, the scraper is attached to the wall for scraping, so that the paint can be applied more stably and evenly on the wall.

Further, both ends of the protective cover are also connected with return pipes, and the return pipes are connected to the main body of the sprayer.

By adopting the above-mentioned technical scheme, since the first nozzle sprays the paint, the protective cover is installed obliquely, and the paint sprayed by the first nozzle will gather and cause dripping when sprayed on the inner wall of the baffle or the protective cover. By setting the return pipe, the accumulated The paint flows back to the sprayer body from the return pipe, which not only avoids the waste of paint, but also prevents the paint from dripping onto the wall, avoiding uneven spraying.

Further, a second nozzle is threadedly connected to the end of the extension rod away from the spray gun, and the second nozzle is sharp.

By adopting the above technical scheme, when the putty sprayer is spraying the corner, the flat first nozzle and the protective cover cannot be extended in. By setting the second nozzle, the thread of the first nozzle is removed and replaced with the second nozzle. Nozzle, you can spray the corner of the wall, no need for an additional putty sprayer for spraying.

Further, the end of the feeding pipe close to the sprayer body is provided with a filter screen.

By adopting the above technical scheme, the filter screen can initially filter the paint, so as to prevent unevenly stirred paint from flowing into the feeding pipe and causing blockage.

Compared with the prior art, the beneficial effects of the utility model are:

(1) By setting the first nozzle into a flat shape, since the first nozzle is flat, when it sprays paint, the center pressure of the first nozzle is basically the same as the pressure at the edge, and the sprayed paint is relatively uniform, and the paint is applied to the wall. After that, it is more uniform, and the first nozzle is equipped with a flat protective cover. After the paint is sprayed, it will be blocked by the protective cover without causing the paint to scatter. Not only is the spray uniform, but the production process is also cleaner;

(2) By setting the rollers, the protective cover can be pulled on the wall through the rollers, and then the first nozzle sprays the paint for spraying. Since the distance between the protective cover and the wall is fixed, the paint spraying is more uniform and will not cause unevenness.
