[0002] At present, the common spraying equipment on the market has only a storage barrel for storing paint, and it needs to be cleaned after use to prevent the paint from sticking to the inner wall of the barrel, which affects subsequent use. In addition, during use, since the feed pipe connected to the spray gun is mostly extended to the bottom of the storage barrel, the paint is drawn out, resulting in poor fluidity of the paint inside the storage barrel, which may cause the paint to precipitate, resulting in poor spraying effect, so improvements are made. Summary of the invention

[0003] The purpose of the present invention is to solve the above problems existing in the background technology and to provide a composite material surface automatic spraying device and a working method thereof.

[0004] The present invention achieves the above-mentioned purpose by adopting the following technical solutions:

[0006] A working method of a composite material surface automatic spraying device, the working method comprising the following steps:

[0007] Step 1: Move the movable device to the inner bottom of the cylinder, then open the control valve and inject the paint into the cylinder;

[0008] Step 2: Start the motor and drive the movable device upward through the screw, so that the paint on the upper end of the movable device passes through the filter plate and moves to the bottom of the movable device to complete the filtration;

[0009] Step 3: Adjust the flow valve, then start the motor in reverse, so that the screw drives the movable device to move downward, and pushes the paint into the tube for spraying. During the downward movement of the movable device, subsequent paint or cleaning liquid can be continuously injected into the upper part of the movable device through the liquid inlet to replenish the paint or clean the cylinder with cleaning liquid.

[0010] Compared with the prior art, the beneficial effects of the present invention are: the present invention is not only convenient for cleaning the inner wall of the cylinder, but also during the spraying process, the movable device moves up and down, and then the stirring blades and the rotatable filter plate drive the paint above and below the movable device to move, which can effectively avoid the phenomenon of paint sedimentation, thereby ensuring the spraying effect.

[0029] The outer diameter of the annular plate II 227 is larger than the diameter of the circular hole 213 .

[0030] The fixing plate 219 is configured to be arc-shaped.

[0031] A working method of a composite material surface automatic spraying device, the working method comprising the following steps:

[0032] Step 1: Move the movable device 2 to the inner bottom end of the cylinder 11, then open the control valve 15 to inject the coating into the cylinder 11;

[0033] Step 2: Start the motor 17, and drive the movable device 2 to move upward through the screw 16, so that the paint on the upper end of the movable device 2 passes through the filter plate 225 and moves to the bottom of the movable device 2, completing the filtration;

[0034] Step three: adjust the flow valve 110, then start the motor 17 in reverse, so that the screw 16 drives the movable device 2 to move downward, and pushes the paint into the tube 19 for spraying. During the downward movement of the movable device 2, subsequent paint or cleaning liquid can be continuously injected into the upper part of the movable device 2 through the liquid inlet 14 to replenish the paint or clean the cylinder 11 with the cleaning liquid.

[0035] The working principle of the present invention is as follows: when the paint is first added to the device, the movable device 2 is moved to the bottom of the cylinder 11, and then the control valve 15 is opened to inject the paint into the cylinder 11; after the paint is filled, the motor 17 is started, and the motor 17 drives the screw 16 to rotate. During the rotation of the screw 16, the slider II 222 and the slider I 212 are restricted by the slide groove 12, so that the movable device 2 cannot rotate. Therefore, after the screw 16 rotates, under the action of the limit block 229, the filter device 22 is driven to move upward, so that a gap is exposed between the filter plate 225 and the floating block 211, and then The paint on the upper end of the filter plate 225 passes through the filter plate 225 and then impacts the floating block 211 to change direction and complete filtering, and finally flows to the lower end of the floating block 211 through the circular hole 213. After all the paint flows to the lower end of the floating block 211, the flow valve 110 is opened, and the motor 17 is started in reverse, so that the screw 16 drives the filter device 22 to move downward. Under the action of buoyancy, the upper end surface of the floating block 211 is close to the lower end of the filter plate 225. During the downward movement of the movable device 2, the control valve 15 can be opened at the same time, so that the subsequent additional paint or cleaning liquid flows to the upper end of the filter device 22.

[0036] In the process of the movable device 2 moving downward, due to the continuous rotation of the screw 16, a plurality of rollers 215 that can roll in the length direction of the screw 16 are provided on the inner wall of the cylinder 214, so that the cylinder 214 can roll along the length direction of the screw 16, and when the screw 16 rotates, the friction between the rollers 215 and the rollers 215 drives the rollers 215 and the cylinder 214 to rotate, thereby driving the stirring blade 216 to rotate, so that the stirring blade 216 drives the paint under the floating block 211 to rotate continuously to prevent the paint from settling, and at the same time, the stirring blade 216 also drives the connecting ring 217 to rotate, and the connecting ring 217 is connected to the outer side of the connecting ring 217. The teeth drive the gear I 2113, the gear II 2114 and the elastic telescopic rod 2115 fixedly connected to the upper end of the gear II 2114 to rotate, so that the gear III 2116 rotates. The elastic telescopic rod 2115 is always in a compressed state, so that the gear III 2116 is always in the annular groove 226. During the rotation of the gear III 2116, the filter plate 225 is driven to rotate through the tooth grooves on the inner wall of the annular groove 226, thereby driving the paint on the upper end of the filter plate 225 to move, and the viscosity of the paint drives the overall paint movement, further preventing the paint on the upper end of the filter device 22 from settling;

[0037] During the upward movement of the movable device 2, i.e., during the process of filtering the paint on the upper end of the filter device 22 and adding it to the lower end of the floating block 211, the filter plate 225 moves upward relative to the floating block 211 under the drive of the screw 16, so that the upper end of the filter plate 225 contacts the fixed plate 219. During the rotation of the filter plate 225 according to the above steps, the upper end surface of the filter plate 225 will always contact the fixed plate 219, and the fixed plate 219 will push the filter residue on the upper end of the filter plate 225 to prevent the filter residue from accumulating on the upper end of the filter plate 225 and affecting the downward flow of the paint. At the same time, during the upward movement of the annular plate I 221, the residue on the inner wall of the cylinder 11 will also be scraped off;

[0038] If the cleaning liquid is introduced from the liquid inlet 14 during the downward movement of the movable device 2, the filter plate 225 rotates when the movable device 2 moves to the lowest point, driving the cleaning liquid to impact the inner wall of the cylinder 11, so that the residue is mixed in the cleaning liquid. When the movable device 2 moves upward, when the residue mixed in the cleaning liquid is at the position of the filter plate 225, the cleaning liquid passes through the filter plate 225, and the residue is retained on the filter plate 225 until the movable device 2 moves to the highest point. Then, the motor 17 is turned off, the cover 13 is opened, and the residue on the upper end of the filter device 22 is cleaned, making cleaning simpler and more convenient. At the same time, after the cleaning liquid moves to the bottom of the floating block 211, the cleaning liquid is sprayed from the spray gun in a spraying manner to clean the spray gun and a small amount of residue in the tube 19.

[0039] In the present invention, the tube 19 does not need to be inserted into the interior of the cylinder 11, thereby preventing residues from being left on the outer wall of the tube 19. Only the interior of the tube 19 needs to be cleaned, thereby simplifying the cleaning steps.

[0040] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other forms of assembly without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-restrictive, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations within the meaning and range of equivalents of the claims be included in the invention.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
