Description

Technical Field

[0001] The utility model relates to the technical field of paint spraying nozzles, and particularly relates to an adjustable paint spraying nozzle. Background Technique

[0002] Paint spraying is a coating method in which paint is dispersed into uniform and fine droplets by means of a spray gun or a disc atomizer with the aid of pressure or centrifugal force and applied to the surface of the workpiece to be coated. After paint spraying, the workpiece has protection to extend the service life of the workpiece, including aesthetics and other special properties. Among them, the paint spraying nozzle is a relatively important component of the paint spraying equipment, controlling the transportation of the paint liquid.

[0003] The prior art (publication number: CN 217190448U) discloses a multi-angle adjustable nozzle for automatic paint spraying, belonging to the technical field of nozzles. It includes a nozzle body, a rotating groove is opened inside the nozzle body, a rotating sphere is arranged inside the nozzle body, the rotating sphere is adapted to the rotating groove, a connecting head is arranged at the top end of the rotating sphere, a nozzle is arranged at the bottom end of the nozzle body, a communicating hose is arranged at the bottom end of the rotating sphere, and the rotating sphere is interconnected with the inside of the nozzle through the communicating hose.

[0004] Although the above patent can adjust the rotating sphere at any angle inside the rotating groove through the cooperation of the nozzle body, the rotating sphere and the communicating hose and then fix it, so that the angle between the nozzle and the connecting head can be changed, there are the following drawbacks. During adjustment, the equipment needs to be shut down and the screw rod needs to be manually rotated to adjust the angle of the nozzle body. The manual adjustment process increases the labor intensity of workers, has a long operation time, and affects the paint spraying efficiency. Therefore, we propose an adjustable paint spraying nozzle. Content of the Utility Model

[0005] The main purpose of the utility model is to provide an adjustable paint spraying nozzle, which can effectively solve the problems in the background technique.

[0006] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] An adjustable paint spraying nozzle includes a vertical plate. A second rotating component is arranged at the upper part of the front end of the vertical plate. A circular groove is opened in the middle of the front end of the vertical plate. A rotating column is movably sleeved in the circular groove. A first rotating component is arranged at the front end and the rear end of the rotating column, and the first rotating component extends to the front side of the rotating column. Fixing plates are installed at the left and right parts of the front end of the rotating column. A rotating shaft is movably sleeved between the two fixing plates. A connecting rod is fixedly sleeved in the middle of the outer surface of the rotating shaft. An adjusting component is installed at the lower part of the outer surface of the connecting rod. A paint spraying head is installed at the front end of the adjusting component.

[0008] Preferably, the first rotating member includes a first motor, which is installed at the rear end of the rotating column. The output end of the first motor movably penetrates through the front side of the rotating column and is fixedly connected with a first bevel gear. The first bevel gear is meshed with a second bevel gear, and the second bevel gear is fixedly sleeved on the rotating shaft.

[0009] Preferably, the second rotating member includes a second motor, which is installed at the upper part of the front end of the vertical plate. The output end of the second motor movably penetrates through the rear end of the vertical plate and is fixedly connected with a gear. The gear is meshed with an annular gear, and the annular gear is fixedly sleeved on the outer cylindrical surface of the rear part of the rotating column.

[0010] Preferably, the adjusting member includes an electric cylinder, which is installed at the lower part of the outer surface of the connecting rod. The output end of the electric cylinder is fixedly connected with a sleeve rod, and the sleeve rod is movably sleeved on the connecting rod.

[0011] Preferably, the paint spraying head is installed at the front end of the sleeve rod.

[0012] Preferably, a guiding groove is formed on the inner cylindrical surface of the circular groove, and a guiding ring is arranged in the guiding groove. The guiding ring is fixedly sleeved on the outer surface of the rotating column.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. By arranging the first rotating member and the second rotating member, the angle of the paint spraying head can be automatically adjusted. When the angle needs to be adjusted, control the first motor to drive the first bevel gear to rotate. The first bevel gear drives the second bevel gear to rotate. The second bevel gear drives the paint spraying head to rotate up and down through the rotating shaft. Control the second motor to drive the gear to rotate. The gear drives the annular gear to rotate. The annular gear drives the paint spraying head to rotate through the rotating column, so as to automatically adjust the angular position of the paint spraying head, without stopping the machine and manual operation by workers, reducing the labor intensity of workers, shortening the adjustment time, and ensuring the painting efficiency.

[0015] 2. By arranging the adjusting member, the distance between the paint spraying head and the workpiece can be adjusted. When the paint spraying head needs to be close to the workpiece, control the output end of the electric cylinder to drive the sleeve rod to move forward. The sleeve rod drives the paint spraying head to be close to the workpiece. When it needs to be far away from the workpiece, control the output end of the electric cylinder to shorten, so that the paint spraying head is far away from the workpiece. By adjusting the distance between the paint spraying head and the workpiece, the coverage range and uniformity of the paint mist can be optimized, ensuring that the paint layer thickness is consistent, avoiding the situation of too thick or too thin coating, and thus improving the spraying quality and surface finish.
