[0010] In the above-mentioned automatic spraying device for the surface of the composite material rod, during the feeding process, it is not easy for gas to enter the supplied paint, so that it is not easy for gas to remain in the paint during the addition of paint, thereby improving the feeding quality. The spraying intelligent controller can flexibly adjust the feeding rate and automatically judge the shortage of materials, and automatically replenish the paint. During the replenishment process, the mixing of new and old paints is reduced, and the old paint is not easy to remain, thereby achieving uninterrupted feeding.

[0011] As a further improvement of the present application, the input end of the input pipe is respectively connected to the feeding pump and the air pump through a multi-way pipe, and the feeding pump and the air pump are both electrically connected to the feeding module.

[0030] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0031] The first implementation method:

[0032] Figure 1-Figure 5The invention shows an automatic spraying device for the surface of a composite material rod, comprising a rod 1, a rotating assembly 2, an automatic displacement platform assembly 4 and a mixing nozzle assembly 3. The rotating assembly 2 is installed at both ends of the rod 1 to drive the rod 1 to rotate. A storage box 5 and a supply box 6 are arranged on the automatic displacement platform assembly 4. The tops of the storage box 5 and the supply box 6 are connected through a transfer pipe 17. The output end of the supply box 6 is connected to the input end of the mixing nozzle assembly 3 through a supply pipe 18. The mixing nozzle assembly 3 is placed above the rod 1 to spray the surface of the rod 1. The storage box 5 supplies the supply box 6. The material in the supply box 6 is The paint is sprayed out through the mixing nozzle assembly 3 to spray the rod 1. During the spraying process, the rotating assembly 2 drives the rod 1 to rotate, and the automatic displacement platform assembly 4 controls the storage box 5, the supply box 6 and the mixing nozzle assembly 3 to reciprocate along the axial direction of the rod 1 to evenly spray the rod 1. The rotating assembly 2 is a rotating mechanism in the prior art for driving the spraying workpiece to rotate, and the automatic displacement platform assembly 4 is a translation mechanism in the prior art for moving along the X-axis and the Y-axis. It is a prior art well known to personnel in this field and is not within the scope of protection of this application. This application will not repeat its specific structure and working principle.

[0033] Multiple groups of storage boxes 5 and supply boxes 6 can be set to transport different types of coatings to the mixing nozzle assembly 3, and mixed and sprayed through the mixing nozzle assembly 3 to improve the spraying effect. For example, spraying a new type of polyurea material onto the surface of the rod 1 can achieve rapid curing at room temperature, high construction efficiency, and improve the wear resistance and weather resistance of the rod 1.

[0034] It is worth mentioning that the bottom of the storage box 5 is connected to an input pipe 15, an input solenoid valve 16 is installed on the input pipe 15, an exhaust head 13 is connected to one side of the upper end of the storage box 5, a piston plate 8 is provided in the inner cavity of the storage box 5, a three-way pipe 9 is penetrated through the piston plate 8, one output end of the three-way pipe 9 is connected to the exhaust head 13 through an exhaust hose 12, and an exhaust solenoid valve 11 is installed at the connection between the exhaust head 13 and the three-way pipe 9, a pumping pump 10 is installed at the other output end of the three-way pipe 9, and a storage proximity switch 20 is installed at the top of the inner cavity of the storage box 5 corresponding to the three-way pipe 9. When the paint is located at the top of the piston plate 8, please refer to Figure 2, air is supplied to the bottom of the piston plate 8 through the input pipe 15, so that the piston plate 8 moves up to squeeze the prepared paint into the inner cavity of the supply box 6, thereby achieving the purpose of supplying the inner cavity of the supply box 6. When the piston plate 8 moves up to the specified position, the paint is input into the inner cavity of the storage box 5 through the input pipe 15. During the paint input process, the gas at the bottom of the piston plate 8 is discharged through the three-way pipe 9, the exhaust hose 12 and the exhaust head 13, and the pumping pump 10 is controlled to work, and the paint at the bottom of the piston plate 8 is transferred to the top of the piston plate 8, and the paint in the storage box 5 is stably input into the inner cavity of the supply box 6, so as to ensure the uniformity of the feeding, and when feeding the storage box 5, it is not easy for the gas to enter the paint supplied to the supply box 6, and in the feeding process, the mixing of new and old paints is reduced, so that the old paint in the inner cavity of the storage box 5 is not easy to remain, thereby improving the spraying quality.

[0035] In addition, a piston plate 24 is provided in the middle of the feed box 6, a pumping pump 25 is installed at the through hole opened on the piston plate 24, a pressurized air bag 29 is installed on the top of the piston plate 24, the inner cavity of the pressurized air bag 29 is connected to a two-way air pump 30 through a ventilation hose, the output end of the transfer pipe 17 extends to the bottom of the inner cavity of the feed box 6 through the conveying channel 23, a glue supply pump 21 is installed between the feed pipe 18 and the inner cavity of the feed box 6, and a hydraulic sensor 28 is installed on the top of the inner cavity of the feed box 6. When the piston plate 8 moves up to squeeze the paint into the inner cavity of the feed box 6, the paint The material will push the piston plate 24 to move upward, and the piston plate 24 pushes the original paint to feed the mixing nozzle assembly 3 through the glue supply pump 21, so that the original paint is not easy to mix with the paint at the bottom of the piston plate 24, and the original paint is used up as much as possible to reduce the residue. The two-way air pump 30 is used to inflate the pressurized air bag 29, and the residual paint can be squeezed to the input end of the glue supply pump 21 to further reduce the residue of the paint. The paint at the bottom of the piston plate 24 can be transferred to the top of the piston plate 24 through the operation of the pumping pump 25, so as to facilitate the supply of new paint to the glue supply pump 21.

[0036] In the present embodiment, a spraying intelligent controller is provided on the automatic displacement platform assembly 4, and a feeding module, a feeding module, an exhaust module and a spraying control module are provided on the spraying intelligent controller. The spraying control module is electrically connected to the rotating assembly 2, the mixing nozzle assembly 3, the automatic displacement platform assembly 4 and the glue supply pump 21 respectively, the feeding module is electrically connected to the feeding module, the pumping pump 25, the hydraulic sensor 28 and the two-way air pump 30 respectively, the feeding module is electrically connected to the exhaust module, the input solenoid valve 16, the pumping pump 10 and the proximity switch 20 on the glue storage, and the exhaust module is electrically connected to the exhaust solenoid valve 11; the feeding module controls the input solenoid valve 16 to open, and the gas is input into the inner cavity of the storage box 5 through the input solenoid valve 16, and the gas pushes the piston plate 18 to move upward to squeeze the paint into the inner cavity of the feeding box 6, and simultaneously pushes the piston plate 24 to move upward to push the paint on the top of the piston plate 24 to At the glue supply pump 21, the hydraulic sensor 28 detects the hydraulic data of the paint entering the glue supply pump 21 and feeds it back to the feeding module. The feeding module determines whether the hydraulic data reaches the preset value (the qualified hydraulic value when the paint is fed to the glue supply pump 21 is preset in the feeding module). When the feeding module determines that the hydraulic data is less than the preset value, it sends a pressurization signal to the feeding module. Otherwise, it sends a pressure reduction signal to the feeding module. The feeding module controls the switching degree of the input solenoid valve 16 to control the gas input speed and flexibly adjusts the feeding rate according to demand; when the piston plate 8 moves up and contacts the proximity switch 20 on the glue storage, the proximity switch 20 on the glue storage sends a signal to the feeding module, and the feeding module sends an exhaust signal to the exhaust module to control the exhaust solenoid valve 11 on the three-way pipe 9 to open, and the gas at the bottom of the piston plate 8 can be discharged through the exhaust head 13. At this time, the paint is input through the input pipe 15. Please refer to Figure 4 , the gas on the top of the paint is discharged through the exhaust head 13, reducing the residual gas in the paint after adding. At the same time, the feeding module feeds back the lack of material signal to the feeding module. The feeding module controls the two-way air pump 30 to inject gas into the inner cavity of the pressurized airbag 29. The volume of the pressurized airbag 29 increases to squeeze the paint to the input end of the glue supply pump 21, and increases the paint pressure here to keep it at a preset value, so as to achieve the purpose of uninterrupted feeding, and ensure that the mixing nozzle assembly 3 always outputs the paint stably and evenly during the feeding process, thereby improving the spraying quality; after the gas at the bottom of the piston plate 8 is exhausted, the exhaust module controls the exhaust solenoid valve 11 to close. At the same time, the feeding module controls the pumping pump 10 to work, and the paint at the bottom of the piston plate 8 is input to the top of the piston plate 8, and the piston plate 8 is gradually reset. The feeding module controls the pumping pump 25 to work, and the paint at the bottom of the piston plate 24 is input to the top of the piston plate 24, and the piston plate 24 is gradually reset. The two-way air pump 30 is controlled to discharge the gas in the pressurized airbag 29, so that the pressurized airbag 29 is reset. After the reset is completed, the gas is injected into the input pipe 15 again to adjust the feeding speed to the glue supply pump 21, and the mixing of new and old paints and the residue of old paints can be reduced, thereby improving the spraying quality.

[0037] Also, see Figure 5 The input end of the input pipe 15 is connected to the feeding pump and the air pump through a multi-way pipe respectively. The feeding pump and the air pump are electrically connected to the feeding module. When it is necessary to introduce gas into the input pipe 15, the feeding module controls the input solenoid valve 16 to open and the air pump to work. When it is necessary to input paint into the input pipe 15, the feeding module controls the input solenoid valve 16 to open and the feeding pump to work. The feeding pump inputs the paint through the input pipe 15 to the bottom of the piston plate 8.

[0038] In addition, the bottom of the piston plate 8 is a concave structure, and the three-way pipe 9 is installed at the highest point of the concave surface of the bottom of the piston plate 8. When the paint is injected into the bottom of the piston plate 8, the gas is discharged through the three-way pipe 9 and the exhaust head 13 at the top. Through the concave design, the gas is gradually concentrated at the input end of the three-way pipe 9, and the gas is completely discharged, reducing the gas remaining in the paint.

[0039] In this implementation, see Figure 1 A nozzle distance adjusting assembly 7 is installed on one side of the feed box 6 close to the mixing nozzle assembly 3. The output end of the nozzle distance adjusting assembly 7 is installed with the mixing nozzle assembly 3 to control the distance between the mixing nozzle assembly 3 and the rod 1. The spraying control module is electrically connected to the nozzle distance adjusting assembly 7. When the rod 1 is sprayed by the mixing nozzle assembly 3, the nozzle distance adjusting assembly 7 can be controlled by the spraying control module to operate, so that the nozzle distance adjusting assembly 7 controls the mixing nozzle assembly 3 to move toward the rod 1 or away from the rod 1 to adjust the spraying distance.

[0040] The second implementation method:

[0041] See also Figure 3-Figure 4 and Figure 6-Figure 9, which is different from the first embodiment, a detection frame 31 is provided at the output end of the exhaust head 13, and the detection frame 31 is rotatably connected to the outer wall of the exhaust head 13 through a rotating shaft. When the paint enters the inner cavity of the detection frame 31, the detection frame 31 loses balance and flips over. A liquid level sensor 14 is installed on the inner wall of the detection frame 31, and the liquid level sensor 14 is electrically connected to the exhaust module. When the paint is injected into the inner cavity of the storage box 5 through the input pipe 15, the gas is discharged through the exhaust head 13. When the paint fills the bottom of the piston plate 8 and enters the exhaust head 13, it will be discharged from the exhaust head 13 into the detection frame 31, and the staff can quickly and intuitively observe the inspection. The paint in the detection frame 31 is detected to determine whether the gas in the paint at the bottom of the piston plate 8 is discharged, and when the paint enters the detection frame 31, it will be detected by the liquid level sensor 14. The liquid level sensor 14 sends the detected data to the exhaust module. The exhaust module determines that the gas has been completely discharged. The exhaust module sends a signal of exhaust completion to the feeding module. The feeding module controls the transfer of the paint at the bottom of the piston plate 8 to the top of the piston plate 8. When the paint enters the inner cavity of the detection frame 31, the detection frame 31 loses balance and flips over. The flipped detection frame 31 opens downward. After the paint flows out, the detection frame 31 flips over and resets again to facilitate the next detection.

[0042] It is worth mentioning that a glue storage lower proximity switch 19 is installed at the bottom of the inner cavity of the storage box 5, and the glue storage lower proximity switch 19 is electrically connected to the feeding module. A glue supply lower proximity switch 26 is installed at the bottom of the inner cavity of the feeding box 6, and a glue supply upper proximity switch 27 is installed at the upper end of the inner cavity of the feeding box 6. The feeding module is electrically connected to the glue supply lower proximity switch 26 and the glue supply upper proximity switch 27 respectively. When the feeding module controls the pumping pump 10 to work, the paint at the bottom of the piston plate 8 is transported to the top of the piston plate 8, and the piston plate 8 moves down and contacts the glue storage lower proximity switch 19. At this time, the lower proximity switch 19 of the glue storage sends a signal to the feeding module that the piston plate 8 has been reset, so that the feeding module can accurately determine the position of the piston plate 8, and promptly control the pumping pump 10 and the feeding pump to stop working, and switch the air pump to work, and quickly push the piston plate 8 up through the air pump to achieve stable feeding; when the piston plate 24 moves down and contacts the lower proximity switch 26 of the glue supply, the lower proximity switch 26 of the glue supply sends a signal to the feeding module that the piston plate 24 has been reset, so that the feeding module can promptly control the pumping pump 25 and the two-way air pump 30 to shut down.

[0043] In addition, the glue supply lower proximity switch 26 and the glue storage lower proximity switch 19 are both embedded in the bottom of the corresponding supply box 6 and storage box 5. When the piston plate 24 and the piston plate 1 8 are reset, the residual amount of paint at the bottom is reduced, making it difficult for old paint to remain.

[0044] In this embodiment, when the material storage box 5 is feeding the material supply box 6, if it is no longer necessary to add paint to the inner cavity of the material storage box 5, please refer to Figure 8At this time, the feeding module controls the pumping pump 25 to work and quickly introduce the paint at the bottom of the piston plate 24 to the top of the piston plate 24. At the same time, in order to make the paint pressure on the top of the piston plate 24 reach the specified value, the feeding module can synchronously control the two-way air pump 30 to inflate the pressurized airbag 29, compress the space of the paint on the top of the piston plate 24, thereby increasing the pressure of the paint, so that the paint can enter the glue supply pump 21 at a preset pressure, stably supply the mixing nozzle assembly 3, so that it can spray the surface of the rod 1 evenly, and improve the spraying quality.

[0045] A filter cavity is provided at the connection between the transfer pipe 17 and the conveying channel 23 , and a filter screen 22 is installed between the filter cavities to filter the paint and reduce the clogging of the mixing nozzle assembly 3 by the solid particles of the paint.

[0046] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
