Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts, and specifically relates to a painting and spraying mechanism for automobile parts. Background Technique

[0002] As is well known, automobile parts are each unit that constitutes an entire automobile and a product serving the automobile. There is a wide variety of automobile parts. With the improvement of people's living standards, people's consumption of automobiles is increasing more and more, and the market for automobile parts has become larger and larger. During the production process of automobile parts, a painting and spraying mechanism is required for spraying.

[0003] The patent with the application number CN202322506749.0 discloses a painting and spraying mechanism for automobile parts, including a spraying box, and a spraying component is arranged on the outer surface of the spraying box; the spraying component includes a liquid storage tank, the upper end surface of the liquid storage tank is fixedly connected with a lid through bolts, the upper end surface of the lid is fixedly connected with a first motor, the output end of the first motor penetrates through the lid movably, and the output end of the first motor is fixedly connected with a stirring rod.

[0004] Although this device avoids the situation of material precipitation or separation, this device stirs by the horizontal rotation of the stirring blades. This stirring method has a good stirring effect on the materials and water in the same water layer, but it cannot effectively roll the materials in the lower part to the upper part for stirring and mixing. When this device is not working, there are more materials deposited below. Using the stirring method of the stirring blades, it is easy to have a higher mixing degree of the materials and water below than that of the materials and water above, thus resulting in water layers with different mixing degrees. Therefore, the stirring effect is not very good. Secondly, the stirring blades and the stirring rod of this device are fixedly arranged. When it is necessary to clean or replace the stirring blades, the stirring blades and the stirring rod need to be cleaned or replaced as a whole, rather than the stirring blades can be disassembled for separate cleaning or replacement. Therefore, the practicality is not very good and there is still room for improvement. Content of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1-4, a painting and spraying mechanism for automobile parts of the utility model, includes a base 1. There is an installation groove 2 on the base 1. An annular air pipe 3 is installed in the installation groove 2. An air inlet pipe 4 is arranged on the left part of the annular air pipe 3. An air pump 5 is installed on the left part of the air inlet pipe 4. Start the air pump 5, and the air pump 5 conveys gas into the annular air pipe 3 through the air inlet pipe 4. Several exhaust pipes 6 are arranged on the upper part of the annular air pipe 3. The gas in the annular air pipe 3 enters into the exhaust pipes 6. There is a baffle 17 on the upper part of the installation groove 2. The baffle 17 is provided with several through holes, and all are in a through and sealed setting with the corresponding exhaust pipes 6. The baffle 17 separates the exhaust pipes 6 from the spraying material. One-way valves 7 are arranged on the upper parts of several exhaust pipes 6. Sprayers 8 are arranged on the upper parts of several one-way valves 7. The gas in the exhaust pipes 6 pushes open the one-way valves 7 and enters into the sprayers 8 and then sprays out, forming an upward air flow, blowing the material deposited on the upper part of the baffle 17 up for mixing, avoiding excessive deposition of the lower material and the concentration of mixing with the water below being higher than that of mixing with the water above. There is a barrel 9 on the upper part of the base 1. The barrel 9 cooperates with the base 1 to hold the spraying material. Several first threaded holes are arranged on the upper part of the barrel 9, and bolts 10 are all threadedly connected thereto. The upper parts of several bolts 10 are threadedly connected with a top plate 11. The top plate 11 is installed on the barrel 9 through the threaded connection mode of the bolts 10 and the first threaded holes. The middle part of the top plate 11 is rotatably connected with a connecting rod 12 through a rotating shaft. A first motor 13 is installed on the upper part of the connecting rod 12. Start the first motor 13, the first motor 13 rotates, driving the connecting rod 12 to rotate. Several second threaded holes 14 are arranged on the lower part of the connecting rod 12, and screws 15 are all threadedly connected thereto. Stirring rods 16 are arranged at one ends of several screws 15. The stirring rods 16 are installed on the connecting rod 12 through the threaded connection mode of the screws 15 and the second threaded holes 14 and rotate along with the rotation of the connecting rod 12, stirring the paint in the barrel 9. Then, along with the upward air flow formed by the gas sprayed out of the nozzle, the material accumulated at the bottom is blown into the upper water layer. Through the stirring of the stirring rods 16, the mixing degree of the material in each water area is balanced as much as possible. There is a gap between one end of each of several stirring rods 16 and the inner wall of the barrel 9, providing enough space for the installation of the stirring rods 16. There is a gap between the lower parts of several stirring rods 16 and the sprayers 8, preventing the stirring rods 16 from colliding with the sprayers 8 when rotating. A first drain pipe is arranged on the right part of the barrel 9. A liquid extraction pump 18 is arranged on the right part of the first drain pipe. A second drain pipe is arranged on the right part of the liquid extraction pump 18. A spraying device 19 is arranged on the right part of the second drain pipe. Start the liquid extraction pump 18, and the liquid extraction pump 18 conveys the well-stirred material in the barrel 9 into the second drain pipe through the first drain pipe, and then conveys it into the spraying device 19 for spraying on automobile parts. The right part of the second drain pipe is connected through and penetrates a spraying box 20. An electric telescopic rod 21 is installed on the upper part of the spraying box 20. The lower part of the electric telescopic rod 21 is rotatably connected with a pressing plate 22 through a rotating shaft.The lower part of the spraying box 20 is rotatably connected with a connecting rod 12 through a rotating shaft. Another pressing plate 22 is arranged on the upper part of the connecting rod 12. The electric telescopic rod 21 is started, and the electric telescopic rod 21 extends, driving the pressing plate 22 to move downward, cooperating with the lower pressing plate 22 to press the automobile parts, and then cooperating with the spraying device 19 to spray pictures. A second motor 23 is installed at the lower part of the connecting rod 12. The second motor 23 is started, and the second motor 23 rotates, driving the lower pressing plate 22 to rotate, and driving the automobile parts and the upper pressing plate 22 to rotate for spraying.

[0024] In summary, for this automobile part painting and spraying mechanism, during use, the staff can start the air pump 5. The air pump 5 conveys gas into the annular air pipe 3 through the air inlet pipe 4, and enters the nozzle through several exhaust pipes 6 and one-way valves 7, and then sprays into the barrel 9 to form an upward air flow, which impacts the materials gathered on the upper part of the base 1 into the water layer above. Then, through the rotation of the first motor 13, the stirring rod 16 is driven to rotate, and the materials impacted to each water layer by the nozzle 8 are stirred and fully mixed with the water in the corresponding water layer. When it is necessary to clean or replace the stirring rod 16 after using for a period of time, the bolt 10 is unscrewed from the first threaded hole, and devices such as the top plate 11 and the connecting rod 12 are removed from the barrel 9. Then, the screw rod 15 is unscrewed from the second threaded hole 14 of the connecting plate, and then the stirring rod 16 can be removed for cleaning or replacement.
