[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and regulate and control the parameters of the conveyed medium. During the valve manufacturing process, a painting device is required to paint the valve surface.

[0003] Chinese Patent No. CN211099738U discloses a valve painting device, including a base plate. A paint storage tank is fixedly connected to one side of the base plate, and a pump body is fixedly connected to the upper end of the paint storage tank. A paint spraying pipe is fixedly connected to the upper end of the base plate. The paint spraying pipe is connected to the output end of the pump body through a connecting pipe. The input end of the pump body extends to the inner bottom of the paint storage tank. Two nozzles are installed on the side of the paint spraying pipe away from the connecting pipe. This painting device can clamp and limit the valve while also rotating the valve after clamping and positioning, thereby enabling comprehensive painting of the valve. Excess paint can be collected for resource recycling and reuse.

[0004] Existing valve painting equipment cannot coordinate the drying and painting processes during valve painting, making it impossible to continuously dry the painted valves. Different equipment is required for valve processing, which affects the integrity of the paint surface and reduces valve processing efficiency during the transfer process. Therefore, a valve painting device is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and solve the problems mentioned in the background, this utility model proposes a valve painting device.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A valve spraying device of this utility model includes a housing; a paint storage tank is installed on one side of the top of the housing, and a feed hole is opened on the top of the paint storage tank. A feed pipe is fixedly connected to the port of the feed hole. A support frame is fixedly connected to the top of one side of the housing, and a conveying pump is installed on the support frame. The input port of the conveying pump is located inside the paint storage tank, and the output port of the conveying pump is connected to a conveying pipe. The other end of the conveying pipe is fixedly connected to a first hollow pipe, and the first hollow pipe is equipped with... There are multiple nozzles. A first hollow tube and a second hollow tube are fixedly connected between the inner walls of the two sides of the housing, and the first hollow tube and the second hollow tube are located on the inner sides of the housing. After the valve is clamped and positioned, when the valve is painted, the paint in the paint tank flows into the nozzle through the action of the delivery pump, so that the paint in the nozzle is sprayed onto the surface of the valve, thereby enabling the valve to be painted. At the same time, under the action of the third motor, the valve after being clamped and positioned can be rotated, thereby enabling the valve to be rotated for painting, making the valve painting more comprehensive.

[0007] Preferably, a drying chamber is installed on the other side of the top of the box body. An air inlet is provided on one side of the top of the drying chamber, and an air inlet pipe is fixedly connected to the port of the air inlet. A first motor is installed at the center of the top of the drying chamber. A fan is rotatably mounted on the output end of the first motor via a rotating shaft, and the fan is located inside the drying chamber. Mounting plates are fixedly connected to both inner walls of the drying chamber, and multiple heating tubes are fixedly connected to the two mounting plates. The heating tubes are located below the fan. A vent is provided at the bottom of the drying chamber, and an air supply pipe is fixedly connected to the port of the vent. The other end of the air supply pipe is fixedly connected to a second hollow tube, which is equipped with multiple air outlets. When the valve is being painted, the fan rotates due to the action of the first motor. With the cooperation of the heating tubes, the hot air generated by the heating tubes is blown through the vent into the air outlets. The hot air ejected from the air outlets can dry the paint on the valve surface, thereby enabling the paint on the valve surface to dry quickly and greatly improving the efficiency of subsequent valve processing.

[0008] Preferably, the bottom of the housing has a mounting groove, and a second motor is mounted on one bottom side of the housing. The output end of the second motor is connected to a bidirectional lead screw, and the other end of the bidirectional lead screw is rotatably mounted on the inner wall of the mounting groove at the end away from the second motor. Two moving blocks are sleeved on the bidirectional lead screw, both of which are located in the mounting groove and are movably connected to it. A clamping plate is fixedly connected to the top of each of the two moving blocks, and a support plate is fixedly connected to one side of one of the clamping plates. A third motor is mounted on the support plate, and the output end of the third motor is connected to a rotating shaft, with the other end of the rotating shaft passing through... A first limiting cone is fixedly connected to the clamping plate, and a second limiting cone is rotatably mounted on the other clamping plate through a bearing seat. Before painting the valve, in order to facilitate precise painting of the valve, when clamping and limiting the valve, the sealing door is opened, and the valve end is fitted onto the first limiting cone. Then, through the action of the second motor, the bidirectional lead screw drives the two clamping plates to move closer to each other, so that the first limiting cone and the second limiting cone also move closer to each other until both the first limiting cone and the second limiting cone abut against both ends of the valve, thereby clamping and fixing the valve to be painted, which facilitates the subsequent precise painting of the valve.

[0009] Preferably, an exhaust vent is provided at the top of one side of the housing, and a connecting pipe is fixedly connected to the port of the exhaust vent. The other end of the connecting pipe is fixedly connected to the purification box. A fixing plate is installed on one side of the housing, and the purification box is installed on the fixing plate. A filter screen and an activated carbon adsorption screen are arranged sequentially inside the purification box. An exhaust vent is provided on the purification box, and an exhaust pipe is fixedly connected to the port of the exhaust vent. When using this device, in order to avoid environmental pollution caused by the direct discharge of gas from the housing, the purification box is set up so that, under the synergistic effect of the filter screen and the activated carbon adsorption screen, a large amount of dust or dirt in the turbid gas can be removed, while also adsorbing toxic substances in the turbid gas. This purifies the turbid gas in the housing. The purified gas is discharged from the body through the exhaust pipe, thereby preventing environmental pollution.

[0010] Preferably, a sealing door is hinged to one side of the port of the housing via a hinge, and an observation window is provided on the sealing door. A handle is installed on one side of the sealing door. When using the device, the observation window facilitates timely observation of the painting status inside the housing.

[0011] The advantages of this utility model are:

[0012] 1. When painting a valve, this utility model uses a delivery pump to allow the paint in the storage tank to flow into the spray head, which then sprays the paint onto the valve surface, thus enabling the valve to be painted. At the same time, under the action of a third motor, the valve, after being clamped and positioned, can be rotated, thus enabling the valve to be rotated for painting, making the valve painting more comprehensive.

[0013] 2. When painting the valve, the first electric motor causes the fan to rotate. With the help of the heating tube, the hot air generated by the heating tube is blown into the air outlet through the vent. The hot air sprayed out of the air outlet can dry the paint on the valve surface, thereby enabling the paint on the valve surface to dry quickly and greatly improving the efficiency of subsequent valve processing.

[0014] 3. When using this utility model, by setting up a purification box, under the synergistic effect of the filter screen and the activated carbon adsorption screen, it can remove a large amount of dust or ash from the turbid gas, while also adsorbing toxic substances in the turbid gas, thereby purifying the turbid gas in the box.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0024] Please see Figure 1-4 As shown, a valve spraying device includes a housing 1; a sealing door 33 is hinged to one side of the housing 1 via a hinge, and an observation window 34 is provided on the sealing door 33. A handle is fitted on one side of the sealing door 33. A paint storage tank 2 is installed on the top side of the housing 1, and a feed hole is opened on the top of the paint storage tank 2. A feed pipe 8 is fixedly connected to the port of the feed hole. A support frame 3 is fixedly connected to the top of one side of the housing 1, and a delivery pump 4 is installed on the support frame 3. The input port of the delivery pump 4 is located inside the paint storage tank 2, and the output port of the delivery pump 4 is connected to a delivery pipe 5. The other end of the delivery pipe 5 is fixedly connected to a first hollow pipe 6, and multiple spray nozzles 7 are fitted on the first hollow pipe 6. The inner walls on both sides of the housing 1 are separated by... The first hollow tube 6 and the second hollow tube 15 are fixedly connected, and the first hollow tube 6 and the second hollow tube 15 are located on the inside sides of the housing 1 respectively. After the valve is clamped and positioned, when the valve is painted, the delivery pump 4 is started, so that the paint in the paint tank 2 is delivered to the first hollow tube 6 through the delivery pipe 5, and then flows into the nozzle 7, so that the paint in the nozzle 7 is sprayed on the surface of the valve, thereby enabling the valve to be painted. At the same time, under the action of the third motor 23, the first limiting cone 24 is rotated, and with the cooperation of the second limiting cone 26, the valve after being clamped and positioned can also be rotated, thereby enabling the valve to be rotated for painting, making the valve painting more comprehensive.

[0025] Please see Figure 4As shown, a drying chamber 9 is installed on the other side of the top of the box body 1. An air inlet is provided on one side of the top of the drying chamber 9, and an air inlet pipe 17 is fixedly connected to the port of the air inlet. A first motor 10 is installed at the center of the top of the drying chamber 9. A fan 11 is rotatably mounted on the output end of the first motor 10 via a rotating shaft, and the fan 11 is located inside the drying chamber 9. Mounting plates 12 are fixedly connected to both inner walls of the drying chamber 9. Multiple heating tubes 13 are fixedly connected to the two mounting plates 12, and the heating tubes 13 are located below the fan 11. A vent is provided at the bottom of the drying chamber 9, and an air inlet pipe 17 is fixedly connected to the port of the vent. There is an air supply pipe 14, and the other end of the air supply pipe 14 is fixed to the second hollow pipe 15. The second hollow pipe 15 is equipped with multiple air outlets 16. When the valve is painted, the first motor 10 is started, which makes the fan 11 rotate. With the cooperation of the heating pipe 13, the hot air generated by the heating pipe 13 is blown into the air supply pipe 14 through the vent hole, then flows into the second hollow pipe 15, and finally enters the air outlets 16. The hot air sprayed out of the air outlets 16 can dry the paint on the surface of the valve, thereby enabling the paint on the surface of the valve to dry quickly and greatly improving the efficiency of subsequent valve processing.

[0026] Please see Figure 5 As shown, the bottom of the housing 1 has a mounting groove 18. A second motor 19 is installed on one side of the bottom of the housing 1. The output end of the second motor 19 is connected to a bidirectional lead screw 20, and the other end of the bidirectional lead screw 20 is rotatably mounted on the inner wall of the mounting groove 18 away from the second motor 19. Two moving blocks are sleeved on the bidirectional lead screw 20. Both moving blocks are set in the mounting groove 18 and are movably connected to the mounting groove 18. The top of each moving block is fixedly connected to a clamping plate 21. A support plate 22 is fixedly connected to one side of one clamping plate 21. A third motor 23 is installed on the support plate 22. The output end of the third motor 23 is connected to a rotating shaft, and the other end of the rotating shaft passes through the clamping plate 21 and is fixedly connected to a first limiting cone 24. The other clamping plate 23 is fixedly connected to a first limiting cone 24. A second limiting cone 26 is rotatably mounted on the valve via a bearing seat 25. Before painting the valve, it needs to be clamped and limited to facilitate precise painting. When clamping and limiting the valve, the sealing door 33 is opened, and the valve port is placed on the first limiting cone 24. Then, the second motor 19 is started, causing the bidirectional lead screw 20 to drive the two moving blocks closer to each other, which in turn drives the two clamping plates 21 to also move closer to each other. This causes the first limiting cone 24 and the second limiting cone 26 to also come closer to each other until both the first limiting cone 24 and the second limiting cone 26 are in contact with both ends of the valve. At this point, the second motor 19 stops operating, thus clamping and fixing the valve to be painted, which facilitates precise painting of the valve later.

[0027] Please see Figure 6As shown, an exhaust port is provided at the top of one side of the box 1. A connecting pipe 27 is fixedly connected to the port of the exhaust port, and the other end of the connecting pipe 27 is fixedly connected to the purification box 29. A fixing plate 28 is installed on one side of the box 1, and the purification box 29 is installed on the fixing plate 28. A filter screen 30 and an activated carbon adsorption screen 31 are arranged sequentially inside the purification box 29. An exhaust port is provided on the purification box 29, and an exhaust pipe 32 is fixedly connected to the port of the exhaust port. When using this device, in order to avoid environmental pollution caused by the direct discharge of gas from the box 1, the turbid gas in the box 1 flows into the purification box 29 through the exhaust port. Under the synergistic effect of the filter screen 30 and the activated carbon adsorption screen 31, a large amount of dust or ash in the turbid gas can be removed, and toxic substances in the turbid gas can also be adsorbed, thereby purifying the turbid gas in the box 1. The purified gas is discharged from the body through the exhaust pipe 32, thereby preventing environmental pollution.

[0028] Working principle: Due to the lack of a corresponding drying mechanism in existing valve painting devices, it is impossible to dry the painted valves after painting, thus reducing the processing efficiency of the valves in the subsequent process. Therefore, a valve painting device is proposed to address the above problem. Before painting the valve, in order to facilitate precise painting, the valve needs to be clamped and limited. When clamping and limiting the valve, the sealing door 33 is opened, and the valve port is fitted onto the first limiting cone 24. Then, the second motor 19 is started, causing the bidirectional lead screw 20 to drive the two moving blocks to move closer to each other, which in turn drives the two clamping plates 21 to move closer to each other, so that the first limiting cone 24 and the second limiting cone 26 also move closer to each other until the first limiting cone 24 and the second limiting cone 26 both abut against the two ends of the valve. At this point, the second motor 19 stops operating, thus clamping and fixing the valve to be painted, which facilitates the subsequent precise painting of the valve.

[0029] After the valve is clamped and positioned, when painting the valve, the delivery pump 4 is started, so that the paint in the paint tank 2 is delivered to the first hollow tube 6 through the delivery pipe 5, and then flows into the nozzle 7, so that the paint in the nozzle 7 is sprayed onto the valve surface, thereby enabling the valve to be painted. At the same time, under the action of the third motor 23, the first limiting cone 24 is rotated, and with the cooperation of the second limiting cone 26, the valve after clamping and positioning is also rotated, so that the valve can be rotated for painting, making the valve painting more comprehensive. When painting the valve, the first motor 10 is started, so that the fan 11 is rotated. With the cooperation of the heating tube 13, the hot air generated by the heating tube 13 is blown into the air supply pipe 14 through the vent hole, then flows into the second hollow tube 15, and finally enters the air outlet 16. The hot air sprayed out of the air outlet 16 can dry the paint on the valve surface, so that the paint on the valve surface can be dried quickly, which greatly improves the efficiency of subsequent valve processing.

[0030] When using this device, in order to avoid environmental pollution caused by the direct discharge of gas from the chamber 1, a purification chamber 29 is set up. The turbid gas in the chamber 1 flows into the purification chamber 29 through the exhaust port. Under the synergistic effect of the filter plate 30 and the activated carbon adsorption plate 31, a large amount of dust or ash in the turbid gas can be removed, and toxic substances in the turbid gas can also be adsorbed, thereby purifying the turbid gas in the chamber 1. The purified gas is discharged from the body through the exhaust pipe 32, thereby preventing environmental pollution.
