Description

Technical Field

[0001] The present invention relates to the technical field of automobile charging pile painting, and in particular to surface painting equipment suitable for protecting automobile charging piles. Background Art

[0002] In the production and maintenance of modern automobile charging piles, surface painting technology plays a vital role. The existing painting equipment uses a coating roller to evenly apply the paint on the surface of the workpiece. Although it can meet the basic coating requirements, it has many shortcomings in terms of paint use efficiency, coating quality and production efficiency. For example, the method of spraying paint through a coating roller lacks precise control of the amount of paint, resulting in uneven use of paint during each spraying process, which in turn causes inconsistent surface coating thickness and surface defects such as sagging and missing paint. This not only affects the appearance quality of the coating, but also weakens the protective performance of the coating and shortens the service life of the charging pile. At the same time, the traditional spraying technology has a long drying time, which limits the efficiency of the production process and cannot meet the needs of rapid production, resulting in an extension of the overall working cycle, increased production costs and waste of resources.

[0009] Preferably, one end of the spring is fixedly connected to the inner side of the square plate, the other end of the spring is fixedly connected to the outer side of the fixed cylinder, and the outer surface of the square plate fits with the outer surface of the eccentric wheel.

[0010] Preferably, the dosing component includes a dosing box, which is fixedly connected to the middle side of the top end of the mounting base, a dual-axis motor is installed on the outer side of the dosing box, one of the output ends of the dual-axis motor is fixedly connected to a transmission shaft, the outside of the transmission shaft is fixedly connected to two sector gears, the inner side of the dosing box is fixedly connected to two limit plates, the inner side of the limit plate is slidably connected to a driving rack plate, and one end of the driving rack plate is fixedly connected to a push plate.

[0011] Preferably, the outer sides of the two sector gears are meshingly connected with the outer side of the driving rack plate, and the outer surface of the push plate is slidably connected with the inner wall of the quantitative box.

[0012] Preferably, it also includes a second connecting pipe, which is connected to the outer surface of the quantitative box, and a pump body is fixedly installed on the outer side of the quantitative box at one end of the second connecting pipe, the output end of the pump body is fixedly connected to the first connecting pipe, and the input end of the first connecting pipe is fixedly connected to the paint spray pipe.

[0013] Preferably, one end of the first connecting pipe is connected to one side of the top end of the quantitative box, and one end of the paint spraying pipe is connected to the outside of the storage cylinder.

[0014] Preferably, the other output end of the dual-axis motor is fixedly connected to the first connecting shaft, the other output end of the first connecting shaft is fixedly connected to the first bevel gear, the outer side of the first bevel gear is meshingly connected to the second bevel gear, and the outer side of the second bevel gear is fixedly connected to the second connecting shaft.

[0015] Working principle: When using this device, first start the pump body to allow the paint inside the storage tube to enter the first connecting tube through the paint spraying tube, and then enter the quantitative box through the first connecting tube. At this time, start the dual-axis motor to rotate the transmission shaft, so as to drive the two fan-shaped gears to intermittently mesh along the outer side of the driving rack plate, so that the driving rack plate moves back and forth along the inner wall of the limit plate, so as to drive the push plate to move synchronously. When the paint inside the quantitative box is filled, close the control valve outside the first connecting tube and open the control valve outside the second connecting tube. At this time, as the push plate moves to the right along the inner wall of the quantitative box, the paint inside the quantitative box is sprayed out through the second connecting tube, so that the paint is sprayed on the outer surface of the car charging pile. Since the length of the driving rack plate is fixed, the amount of each spray is fixed, which ensures the consistency of the coating of each sprayed component and avoids surface defects caused by uneven spraying. In addition, by accurately controlling the amount of paint required for each spraying, paint waste is significantly reduced, thereby reducing operating costs; At this time, the servo motor is started to drive the driving screw to rotate, so that the threaded frame is driven to move up and down along the outer surface of the driving screw, so that the paint sprayed from the paint spray tube is evenly sprayed on the outer surface of the charging pile, so that the paint can be evenly covered on various complex surface shapes, significantly reducing the uneven coating thickness or omission caused by a single spraying direction; In addition, when the output end of the servo motor rotates, the eccentric wheel will also be driven to rotate. Since the square plate and the eccentric wheel are in contact with each other, the eccentric wheel can drive the square plate to move back and forth when in contact. When the square plate moves, the movable rod is driven to move synchronously. When the rubber piston moves along the inner wall of the fixed cylinder, when the rubber piston moves downward along the inner wall of the fixed cylinder, the one-way valve inside the air intake pipe is closed, and the one-way valve inside the first jet pipe is opened. At this time, the air inside the fixed cylinder is discharged into the interior of the heating box through the first jet pipe, and after being heated by the electric heating wire inside the heating box, it is discharged into the interior of the jet rack through the second jet pipe and discharged through the jet rack, thus accelerating the drying speed of the paint, thereby shortening the overall spraying cycle. This improves production efficiency and allows multiple spraying in the same workflow, further enhancing the uniformity and adhesion of the coating.

[0016] Finally, in the process of spraying paint, the other output end of the dual-axis motor is started to drive the first connecting shaft and the first bevel gear to rotate coaxially. Since the first bevel gear and the second bevel gear are meshed with each other, the rotation of the first bevel gear will drive the second bevel gear to rotate synchronously, thereby driving the second connecting shaft to rotate synchronously, thereby driving the stirring shaft inside the storage cylinder to rotate, mixing the paint inside the storage cylinder, and ensuring the uniformity and stability of the paint.

[0017] The present invention provides a surface painting device suitable for protecting a car charging pile. It has the following beneficial effects: 1. The present invention can be configured to precisely control the amount of paint sprayed by adding a metering component to achieve quantitative spraying. The precise control of the paint amount ensures the consistency of the coating on each sprayed component and avoids surface defects caused by uneven spraying amount. In addition, by precisely controlling the amount of paint required for each spraying, paint waste is significantly reduced, thereby reducing operating costs.

[0018] 2. The present invention can spray repeatedly on the surface of the charging pile by adding a reciprocating spraying component, so that the paint can be evenly covered on various complex surface shapes, significantly reducing the uneven coating thickness or omission caused by a single spraying direction. This method effectively improves the adhesion and durability of the coating, ensuring long-term protection of the charging pile in harsh environments.

[0019] 3. The present invention can achieve rapid drying of the paint when the reciprocating paint spraying assembly is working by adding a drying assembly, and accelerate the drying speed of the paint by providing appropriate heat and airflow through the drying assembly, thereby shortening the overall spraying cycle. This improves production efficiency and allows multiple spraying in the same work process, further enhancing the uniformity and adhesion of the coating. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Please see attached Figure 1 - Attachment Fig. 9 The embodiment of the present invention provides a surface painting device suitable for protecting a car charging pile, including: A mounting base plate 1, which serves as a support carrier for the entire device, has a storage cylinder 6 fixedly connected to one side of the top of the mounting base plate 1, universal wheels 5 are installed at the four corners of the bottom of the mounting base plate 1, and a push handle 4 is fixedly connected to one side of the mounting base plate 1; The mounting base plate 1 is the foundation of the device and provides structural support to ensure that each component can be safely and firmly fixed thereon to avoid tilting or collapse during use.

[0024] The storage cylinder 6 is fixed to one side of the top end of the mounting base plate 1 and is responsible for storing the paint or other materials to be sprayed.

[0025] Universal wheels 5 enhance the mobility of the entire device. Universal wheels allow the device to be moved flexibly in different directions to adapt to changes in the working environment.

[0026] A reciprocating painting assembly, which is installed on one side of the top of the mounting base plate 1 and is used to paint the outer surface of the vehicle charging pile; The reciprocating paint spraying assembly includes a mounting frame 205, which is fixedly connected to one side of the top of the mounting base plate 1, and a servo motor 201 is installed on the top of the mounting frame 205, and a driving screw 202 is fixedly connected to the output end of the servo motor 201, and the external thread of the driving screw 202 is connected to the threaded frame 203; A guide rod 204 is slidably connected to a through hole on one side of the inner side of the threaded frame 203. The upper and lower ends of the guide rod 204 are fixedly connected to the inner wall of the mounting frame 205. The end of the driving screw 202 away from the servo motor 201 is movably connected to the inner bottom wall of the mounting frame 205 through a bearing. Specifically, by starting the servo motor 201 to drive the driving screw 202 to rotate, the threaded frame 203 is driven to move back and forth up and down along the outer surface of the driving screw 202, so that the paint sprayed from the paint spray tube 804 is evenly sprayed on the outer surface of the charging pile. In this way, the paint can be evenly covered on various complex surface shapes, significantly reducing the uneven coating thickness or omissions caused by a single spraying direction.

[0027] A quantitative component, which is installed on the outside of the reciprocating paint spraying component and is used to configure and accurately control the amount of paint sprayed to achieve quantitative spraying; The quantitative component includes a quantitative box 702, which is fixedly connected to the middle side of the top of the installation base plate 1, a double-axis motor 701 is installed on the outside of the quantitative box 702, one of the output ends of the double-axis motor 701 is fixedly connected to a transmission shaft 703, the outside of the transmission shaft 703 is fixedly connected to two sector gears 704, the inside of the quantitative box 702 is fixedly connected to two limit plates 10, the inside of the limit plate 10 is slidably connected to a driving rack plate 705, and one end of the driving rack plate 705 is fixedly connected to a push plate 706; Specifically, by starting the dual-axis motor 701, the transmission shaft 703 rotates, so that the two sector gears 704 are intermittently meshed along the outer side of the driving rack plate 705, so that the driving rack plate 705 moves back and forth along the inner wall of the limit plate 10, so as to drive the push plate 706 to move synchronously. When the paint inside the quantitative box 702 is filled, the control valve outside the first connecting pipe 801 is closed, and the control valve outside the second connecting pipe 802 is opened. At this time, as the push plate 706 moves to the right along the inner wall of the quantitative box 702, the paint inside the quantitative box 702 is sprayed out through the second connecting pipe 802, so that the paint is sprayed on the outer surface of the car charging pile. Since the length of the driving rack plate 705 is fixed, the amount of each spraying is fixed, which ensures the consistency of the coating of each spraying component and avoids surface defects caused by uneven spraying. In addition, by accurately controlling the amount of paint required for each spraying, the waste of paint is significantly reduced, thereby reducing operating costs.

[0028] The outer sides of the two sector gears 704 are meshed with the outer sides of the driving rack plate 705, and the outer surface of the push plate 706 is slidably connected with the inner wall of the quantitative box 702; A drying component, which is installed outside the reciprocating spray painting component and is used to heat the coating after spraying to accelerate the drying process of the coating; The drying assembly includes a fixed cylinder 302 and an eccentric wheel 308. The fixed cylinder 302 is fixedly connected to one side of the top of the mounting frame 205. The interior of the fixed cylinder 302 is slidably connected to a rubber piston 311. The outer side of the rubber piston 311 is slidably connected to a movable rod 310. The outer side of the movable rod 310 is sleeved with a spring. One end of the movable rod 310 is fixedly connected to a square plate 301. The eccentric wheel 308 is fixedly connected to the output end of the servo motor 201. The outer side of the fixed cylinder 302 is connected to an air intake pipe 304. The outer side of the fixed cylinder 302 is also connected to a first jet pipe 305. Check valves 309 are installed on the inner sides of the air intake pipe 304 and the first jet pipe 305. The other side of the first jet pipe 305 is fixedly connected to a heating box 306. The outer side of the heating box 306 is installed with a second jet pipe 307. One end of the second jet pipe 307 is fixedly connected to a jet frame 303.

[0029] One end of the spring is fixedly connected to the inner side of the square plate 301, and the other end of the spring is fixedly connected to the outer side of the fixed cylinder 302. The outer surface of the square plate 301 fits the outer surface of the eccentric wheel 308. Specifically, the rubber piston 311 slides inside the fixed cylinder 302 and is responsible for promoting the flow of air.

[0030] The movable rod 310 is connected to the rubber piston 311, and is connected to the square plate 301 through a spring to provide necessary support and movement. The eccentric wheel 308 is connected to the servo motor 201. When the motor rotates, the eccentric wheel 308 also rotates. The air intake pipe 304 and the first air injection pipe 305 are used for air intake and exhaust respectively, and the built-in check valve 309 controls the direction of air flow. The heating box 306 is used to heat the air to improve the drying effect.

[0031] After the servo motor 201 is started, the eccentric wheel 308 rotates, pushing the square plate 301 to reciprocate. The movement of the square plate 301 drives the movable rod 310 and the rubber piston 311, causing the rubber piston 311 to move up and down on the inner wall of the fixed cylinder 302. When the rubber piston 311 moves downward, the one-way valve 309 in the air inlet pipe 304 is closed, and the one-way valve 309 in the first jet pipe 305 is opened. At this time, the air in the fixed cylinder 302 is discharged into the heating box 306 through the first jet pipe 305. After being heated by the electric heating wire in the heating box 306, the warm air is discharged through the second jet pipe 307. The discharged hot air is ejected through the jet rack 303 to quickly heat and dry the paint.

[0032] The system can effectively speed up the drying of the paint, thereby shortening the spraying cycle and improving production efficiency. Since multiple spraying can be performed in the same workflow, the uniformity and adhesion of the coating are enhanced, improving the quality of the final product.

[0033] The mixing assembly is installed on one side of the top of the installation base plate 1 and is used to fully stir the paint.

[0034] It also includes a second connecting pipe 802, which is connected to the outer surface of the quantitative box 702, and a pump body 803 is fixedly installed on the outer side of the quantitative box 702 at one end of the second connecting pipe 802, and the output end of the pump body 803 is fixedly connected to the first connecting pipe 801, and the input end of the first connecting pipe 801 is fixedly connected to the paint spraying pipe 804; one end of the first connecting pipe 801 is connected to one side of the top of the quantitative box 702, and one end of the paint spraying pipe 804 is connected to the outer side of the storage cylinder 6; Specifically, the quantitative box 702 is used to store and accurately control the amount of paint to ensure that the amount of paint sprayed each time is stable. The second connecting pipe 802 is used to connect the quantitative box 702 and the pump body 803 to achieve the flow of paint. The first connecting pipe 801 is used to connect the pump body 803 and the paint spraying pipe 804 to transfer the paint to the spraying device.

[0035] When the system starts working, the pump body 803 is first started. The start of the pump body 803 will generate negative pressure, thereby extracting the paint inside the storage tube 6. The paint flows to the second connecting pipe 802 through the outlet of the storage tube 6, and the flow process depends on the suction effect of the pump body 803. The paint flows into the outer surface of the quantitative box 702 through the second connecting pipe 802. The quantitative box 702 is designed to accurately control the storage and release of the paint to ensure that the amount of paint is stable during the spraying process.

[0036] The other output end of the dual-axis motor 701 is fixedly connected to the first connecting shaft 901, the other output end of the first connecting shaft 901 is fixedly connected to the first bevel gear 902, the outer side of the first bevel gear 902 is meshingly connected to the second bevel gear 903, and the outer side of the second bevel gear 903 is fixedly connected to the second connecting shaft 904.

[0037] Specifically, the second connecting shaft 904 is fixedly connected to the outer side of the second bevel gear 903 and is responsible for transmitting the rotation to the stirring shaft inside the storage cylinder 6 .

[0038] When the dual-shaft motor 701 is started, the rotational power at its output end is transmitted to the first bevel gear 902 through the first connecting shaft 901. The rotation of the first bevel gear 902 drives the second bevel gear 903 to rotate synchronously. Due to the precise meshing of the two bevel gears, the rotational power is efficiently transmitted to the second connecting shaft 904. As the second connecting shaft 904 rotates, the stirring shaft inside the storage barrel 6 starts to rotate, thereby effectively stirring and mixing the paint.

[0039] The device achieves high torque output through a multi-stage gear transmission system, which can maintain a stable stirring effect under different workloads, effectively prevent coating stratification and precipitation, and ensure the uniformity and stability of the coating. This design not only improves the stirring efficiency, but also extends the service life of the equipment and reduces maintenance costs.

[0040] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
