In addition, the present disclosure provides examples of various specific processes and materials, but one of ordinary skill in the art may recognize applications of other processes and/or use of other materials.

Referring to fig. 1-3, the utility model provides an anti-deposition spraying machine, which comprises a base 1, a cylindrical material storage tank 2 arranged on the base, a buffer tank 3, an air pump 4 and a spray gun 5; the buffer tank 3 is respectively connected with the material storage tank 2, the air pump 4 and the spray gun 5 through pipelines; the stirring device also comprises a rotating shaft 6 coaxially arranged in the material storage tank 2, a stirring plate 7 sleeved on the rotating shaft, and a motor 8 arranged at the bottom of the material storage tank and used for driving the rotating shaft 6 to rotate; the stirring plate 7 is a rectangular plate (namely, the cross section of the stirring plate 7 is on the diameter of the cross section of the inner cavity of the storage tank) which is positioned on the longitudinal section of the inner cavity of the storage tank, the two side edges of the stirring plate are close to the side wall of the storage tank, the lower end of the stirring plate is close to the bottom of the storage tank, and a plurality of through holes 7.1 are uniformly formed in the stirring plate. The close proximity means that a small gap is formed between the edge of the stirring plate 7 and the side wall and the bottom of the storage tank, and the gap is subject to the condition that the stirring plate 7 is not hindered from rotating.

The working principle of the anti-deposition spraying machine is as follows: the paint flows into the buffer tank 3 from the storage tank 2, the air pump 4 conveys high-pressure air to the buffer tank 3 to convey the paint to the spray gun 5, and finally the paint is atomized and sprayed onto a wall body by the spray gun. Drive stirring board 7 through motor 8 and rotate when using, stir the coating on whole longitudinal section in the storage tank 2 simultaneously, can prevent effectively that the coating from deposiing, when the stirring board passes through, the coating can flow through from the clearing hole 7.1 on the stirring board and reach the dispersion effect, prevents the coating aggregation granulation to can guarantee the spraying quality and avoid the spray gun to block up.

Further, as shown in fig. 1 and 3, an annular guide rail 2.1 is arranged on the inner wall of the storage tank 2, and a corresponding guide opening 7.2 is formed in the stirring plate 7 and is slidably connected with the annular guide rail. Through the matching effect of the guide port and the annular guide rail, the stirring plate 7 can be ensured to be always on the longitudinal section of the inner cavity of the material storage tank, and the stirring plate 7 is prevented from being clamped and blocked due to deflection; bending of the rotating shaft 6 due to shear forces is avoided, which is particularly important, particularly because the rotating shaft 6 is of a cantilever structure and is easy to bend and deform.

In some embodiments, two annular guide rails 2.1 are detachably provided, and the two annular guide rails respectively face the upper end and the lower end of the stirring plate 7 (as shown in fig. 1); a sleeve part 7.3 sleeved with the rotating shaft 6 is arranged in the middle of the stirring plate 7 and is connected with the rotating shaft 6 in a key mode (as shown in figure 2); four corners of the stirring plate are provided with guide ports 7.2 which are L-shaped guide ports, the guide port at the upper end is abutted against the bottom of the corresponding annular guide rail, and the guide port at the lower end is abutted against the top of the corresponding annular guide rail (as shown in figures 1 and 2). Because the limiting function of two ring rail 2.1, need not to link firmly between stirring board 7 and the pivot 6 and also can not deviate from, this structure can make things convenient for the maintenance of installing and removing of stirring board 7, when dismantling, demolish the ring rail 2.1 of upside earlier, can directly take out stirring board 7 from pivot 6.

Specifically, the annular guide rail 2.1 is fixedly connected with the storage tank 2 through a screw 2.2, and the screw 2.2 is assembled from the outer side of the storage tank 2, as shown in fig. 3. When the annular guide rail 2.1 is disassembled, the screw 2.2 is directly disassembled from the outside, so that the annular guide rail 2.1 can be taken out, the operation is convenient and fast, and objects cannot block the screwdriver. In order to prevent the coating from flowing out of the mounting holes of the screws 2.2, a sealing ring can be arranged between the annular guide rail 2.1 and the inner wall of the storage tank 2.

Preferably, the axes of adjacent through holes 7.1 in said stirring plate 7 are not parallel, see fig. 2. When the coating flows through different through holes 7.1, the coating has different directions to form turbulent flow, thereby more effectively stirring the coating uniformly and preventing aggregation and granulation.

Further, as shown in fig. 1 and 3, a top cover 9 is provided on the upper end of the storage tank 2, and a vent hole 9.1 is provided on the top cover. Set up the top cap and can prevent that coating from overflowing, and set up the air vent and can make 2 inner chambers of storage tank and atmosphere intercommunication, avoid coating because the negative pressure can't flow in buffer tank 3 smoothly.

Further, as shown in fig. 3, a sealing ring 9.2 is disposed between the top cover 9 and the storage tank 2, and the top cover 9 and the storage tank 2 are connected by a plurality of hasps 2.3.

In this embodiment, as shown in fig. 1, a switching valve 10 is disposed on a pipeline between the storage tank 2 and the buffer tank 3, and the nozzle 5.1 of the spray gun 5 can be inserted into the vent hole 9.1. When spraying is carried out, the switch valve 10 is opened to enable the coating to flow into the buffer tank 3, when the spraying work is finished, the switch valve 10 can be closed, the nozzle 5.1 of the spray gun 5 is inserted into the vent hole 9.1, the air pump 4 is started, and the coating in the buffer tank 3, the spray gun 5 and the connecting pipeline is sprayed back to the storage tank 2, so that the blockage caused by solidification of the residual coating in the buffer tank 3, the spray gun 5 and the connecting pipeline after the machine halt is avoided.

In a preferred embodiment, see fig. 1 and 3, a fixing sleeve 9.3 for fixing the spray gun 5 is arranged on the upper side of the vent hole 9.1, a boss 9.3a for pressing the trigger 5.2 of the spray gun is arranged at the upper end of the fixing sleeve, and the gun body 5.3 of the spray gun can be inserted into the fixing sleeve 9.3 and the nozzle 5.1 of the spray gun extends into the vent hole 9.1 after the fixing sleeve is inserted. When residual paint is sprayed back, the gun body 5.3 is directly inserted into the fixed sleeve 9.3, and the bulge part 9.3a presses the trigger 5.2, so that the operation of holding by hand is not needed, and the use convenience is improved.

Preferably, an elastic ring 5.4 can be provided on the gun body 5.3 of the spray gun, which elastic ring serves to increase the friction between the gun body 5.3 and the fixing sleeve 9.3. The elastic ring 5.4 may be, but is not limited to, a rubber ring, a cow's leather ring, etc., and by increasing the friction force, it is ensured that the protrusion 9.3a effectively presses the trigger 5.2.

Furthermore, see fig. 1, the base 1 is provided with universal wheels 1.1 and a push handle 1.2 for easy movement.

In summary, although the present invention has been described with reference to the preferred embodiments, the above-mentioned preferred embodiments are not intended to limit the present invention, and those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and the embodiments are substantially the same as the present invention.
