Description
Technical Field
[0001] This invention relates to the field of spraying equipment technology, specifically to an intelligent spraying device with adaptive curved surface function. Background Technology
[0002] In the production of workpieces, in order to easily give the workpiece surface different colors or improve the workpiece's corrosion resistance, a spraying device is usually used to spray the corresponding paint layer onto the surface of the workpiece.
[0003] For example, a spraying device for coating spraying with adjustable spraying range disclosed in CN215465478U includes a base and a pair of side plates disposed on both sides of the top of the base; an adjustment mechanism is provided between the tops of the pair of side plates, the adjustment mechanism includes a first slider slidably disposed on the pair of side plates, two first slide rods fixed side by side between the two first sliders, and a second slider movably sleeved on the two first slide rods, the top of the second slider is provided with a handle, and the bottom of the second slider is mounted with a spray head through a first electric push rod.
[0004] The existing technology has the following technical problems: In order to ensure the uniformity of spraying, the existing spraying device usually only allows the nozzle to perform a single movement, which is not convenient to change the movement trajectory of the nozzle according to different spraying surfaces. As a result, when the nozzle moves in a straight line and needs to spray the curved surface of the workpiece, the nozzle can only move along a direction parallel to the tangent of the curved surface. This results in uneven paint concentration on the curved surface. When the nozzle moves in an arc and needs to spray the flat surface of the workpiece, the arc-shaped movement of the nozzle will also cause uneven paint concentration on the flat surface.
[0005] For example, a spraying device for metal sheets disclosed in CN209901557U includes a housing, a glue storage device at the top of the housing, a glue outlet pipe rotatably connected to the bottom of the glue storage device, a glue outlet cylinder at the lower end of the glue outlet pipe, a spray nozzle connected to the outer wall of the glue outlet cylinder through several glue outlet holes, a connecting rod fixed to the bottom end of the glue outlet cylinder, a third gear sleeved on the connecting rod, multiple rotating shafts vertically arranged around the connecting rod, a fourth gear meshing with the third gear sleeved on the rotating shaft, a first mounting plate at the upper end of the rotating shaft, and a second mounting plate rotatably connected to the inner top wall of the housing through multiple electric telescopic rods.
[0006] The existing technology has the following technical problems: When the existing spraying device sprays the workpiece, it is not convenient to protect the paint. As a result, after the spray nozzle sprays the paint onto the workpiece, some of the paint tends to adhere to the inner wall of the device. As the paint accumulates on the inner wall of the equipment, after the spraying is completed, the adhered paint tends to emit an irritating odor, which in turn affects the surrounding workers.
[0007] For example, a core spraying device with publication number CN209205613U includes a spray gun, a track, and a water tank. The track is located above the water tank, and a worktable for placing the core to be sprayed is set inside the water tank. A robotic arm is installed below the track and moves back and forth within the track, holding the spray gun and aiming it at the worktable below. A high-level water tank is set on one side of the water tank. Water in the water tank is pumped into a water pipe that extends into the upper part of the high-level water tank. Water is pumped to a high level and continuously overflows from the high-level water tank, forming a water curtain. Paint particles generated by the spray gun in the air are adsorbed and filtered by the water curtain in the device. The spray gun moves forward or backward at a uniform speed with the robotic arm within the track, resulting in uniform spraying and high efficiency.
[0008] The existing technology has the following technical problems: In order to facilitate the absorption of excess paint after spraying, the existing spraying device adds a water curtain to the device to adsorb the paint. However, after the paint is absorbed by the water curtain, it is not easy to filter the paint residue. As a result, after the water pump circulates and draws water, the paint residue in the water source can easily enter the pipeline and cause the pipeline to be blocked.
[0009] Therefore, we propose an intelligent spraying device with adaptive curved surface function to solve the problems mentioned above. Summary of the Invention
[0010] The purpose of this invention is to provide an intelligent spraying device with adaptive curved surface function to solve the problems mentioned in the background art. In order to ensure the uniformity of spraying, the existing spraying devices on the market usually only allow the nozzle to perform a single movement, which is not convenient to change the movement trajectory of the nozzle according to different spraying surfaces. When spraying the workpiece, it is not convenient to protect the paint. As a result, after the nozzle sprays the paint onto the workpiece, some paint easily adheres to the inner wall of the device. After the paint is absorbed by the water curtain, it is not convenient to filter the paint residue. As a result, after the water pump circulates and draws water, the paint residue in the water source can easily enter the pipeline and cause pipeline blockage.

Furthermore, the surface of the heat insulation shell is provided with a heat insulation layer, which is used to prevent the heat exchange between the heat insulation shell and the external environment.
[0018] By adopting the above technical solution, when water enters the interior of the spray block, the water is sprayed downwards through the evenly distributed nozzles at its lower end, thus forming a water curtain.

A positioning magnet is provided on the side of the electromagnet and is fixed to the paint spray head. A slide rod is fixedly connected to the upper end of the movable rack and is mounted through the support block. The support block is fixed to the top of the interior of the heat insulation housing.
[0020] Preferably, the transmission gear and the movable rack are meshed, and the upper end of the movable rack is fixedly connected to a slide rod that can slide on the support block.
[0021] By adopting the above technical solution, the forward and reverse rotation of the transmission gears enables the meshing movable rack to move back and forth.
[0022] Preferably, the self-cleaning structure comprises a main airbag, an air supply pipe, a pushing airbag, a piston rod, a limiting post, a negative pressure chamber, a toggle rod, a connecting pipe, and a cleaning nozzle. The main airbag is attached to the end of the sliding rod. The main airbag and the pushing airbag are connected to each other through the air supply pipe. The pushing airbag is attached between the upper end of the piston rod and the inside of the limiting post. The limiting post is fixed inside the heat insulation shell. The lower end of the piston rod extends into the inside of the negative pressure chamber. The upper end of the piston rod is fixedly connected to a toggle rod. The upper end of the toggle rod extends into the inside of the paint storage box. The negative pressure chamber is connected to the cleaning nozzle through the connecting pipe. The cleaning nozzle is fixed on the left and right sides inside the water tank. The cleaning nozzle is located below the barrier net.
[0023] Preferably, the airflow inside the main airbag can enter the interior of the propulsion airbag through the air supply pipe, and both the main airbag and the propulsion airbag are made of elastic rubber material.
[0024] By adopting the above technical solution, when the main airbag is subjected to external pressure, the airflow inside it can enter the interior of the propulsion airbag through the air supply pipe.
[0025] Preferably, the piston rod and the actuating rod are fixedly connected, and the actuating rod can slide on the paint storage box.

[0030] By adopting the above technical solution, the water source sprayed upward through the branch nozzles can be used to reverse-wash the barrier net, preventing paint residue from clogging the holes in the barrier net.
[0031] Compared with the prior art, the beneficial effects of the present invention are: the intelligent spraying device with adaptive arc surface function can easily change the spraying trajectory according to different shapes of spraying surfaces, and can also adsorb excess paint through water curtain, and prevent paint residue from entering the pipe during the water source recycling process.
[0032] 1. Equipped with a transmission gear, the spray head is fixed to the transmission gear by engaging the positioning magnet and electromagnet on the spray head. The reciprocating rotation of the transmission gear drives the spray head to reciprocate, thus adapting to the painting of curved surfaces. At the same time, the positioning magnet on the spray head can be engaged with the electromagnet on the movable rack, thus fixing the spray head to the movable rack. The reciprocating rotation of the transmission gear can drive the movable rack to move the spray head left and right, thus adapting to the painting of flat surfaces.
[0033] 2. A spray block is installed. The second pump can circulate and draw water from the pool into the spray block. The water sprayed from the nozzles at the bottom of the spray block forms a water curtain. The water curtain blocks the paint and prevents it from being sprayed onto the inner wall of the insulation shell. At the same time, the heater inside the pool can change the temperature of the water. By changing the water temperature, the temperature inside the insulation shell can be adjusted to a suitable range according to actual needs.
[0034] 3. Equipped with a cleaning nozzle, the piston rod reciprocates up and down inside the limiting post, allowing the actuating rod at the upper end of the piston rod to move inside the paint storage box. The movement of the actuating rod improves the flowability of the paint inside the storage box, preventing paint separation. At the same time, the reciprocating movement of the piston rod allows the cleaning nozzle to draw and squeeze water from the water tank. The water intake and drainage of the cleaning nozzle improves the flowability of the water in the tank, increasing the heating efficiency of the heater. Furthermore, the upward spray of water from the cleaning nozzle can backwash the upper filter screen, preventing paint residue from clogging the filter screen and affecting its normal filtration function.

[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0045] Please see Figures 1-8 The present invention provides the following two embodiments:
[0046] Example 1:
[0047] Existing spraying devices, in order to ensure uniform spraying, typically restrict the nozzle to a single movement pattern, making it difficult to adjust the nozzle's trajectory according to the different spraying surfaces. This results in uneven paint concentration across the curved surface when the nozzle moves in a straight line to spray the workpiece's curved surface. Similarly, when the nozzle moves in an arc to spray the workpiece's flat surface, the arc-shaped movement of the nozzle also leads to uneven paint concentration across the flat surface. To address this technical problem, this embodiment discloses the following technical content, such as... Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown;
[0048] An intelligent spraying device with adaptive curved surface function includes a heat-insulating shell 1, a protective door 2 hinged to the side of the heat-insulating shell 1, and a paint storage box 3 fixedly installed at the upper middle of the heat-insulating shell 1. The upper end of the paint storage box 3 is connected to a first pump 4, and the first pump 4 is connected to the paint storage box 3 through an extraction pipe 5. The first pump 4 is connected to the spray head 7 through a delivery pipe 6. The spray head 7 is installed on a control structure 16. The control structure 16 changes the movement path of the spray head 7 to adapt to flat or curved surface spraying. The control structure 16 consists of a servo motor 161, a transmission gear 162, a movable rack 163, an electromagnet 164, a positioning magnet 165, a slide bar 166, and a support block. The system comprises 167 components, with a servo motor 161 fixed to the back of the heat insulation housing 1. The output end of the servo motor 161 extends into the interior of the heat insulation housing 1, and a transmission gear 162 is fixedly connected to the output end of the servo motor 161. A movable rack 163 is meshed with the upper part of the transmission gear 162. Electromagnets 164 are embedded on the sides of both the movable rack 163 and the transmission gear 162. A positioning magnet 165 is provided on the side of the electromagnet 164, and the positioning magnet 165 is fixed to the paint spray head 7. A slide rod 166 is fixedly connected to the upper end of the movable rack 163, and the slide rod 166 is mounted through the support block 167. The support block 167 is fixed to the top of the interior of the heat insulation housing 1. The transmission gear 162 and the movable rack 163 are meshed, and the slide rod 166 fixedly connected to the upper end of the movable rack 163 can slide on the support block 167.
[0049] The working principle of this embodiment is as follows: When it is necessary to spray paint the curved surface of the workpiece, the workpiece is placed on the upper end of the support plate 9 and fixed. Then, the electromagnet 164 on the side of the transmission gear 162 is energized, so that the positioning magnet 165 on the spray head 7 and the electromagnet 164 on the transmission gear 162 attract each other, thus fixing the spray head 7 to the transmission gear 162. Then, by turning on the first pump 4, the paint in the paint storage box 3 is transported to the inside of the spray head 7 through the extraction pipe 5 and the delivery pipe 6. Then, the transmission gear 162 is reciprocated by the servo motor 161. The reciprocating rotation of the transmission gear 162 drives the side spray head. 7 rotates synchronously, thereby achieving uniform spraying of paint on the curved surface using the rotating paint head 7. When it is necessary to spray paint on the flat surface of the workpiece, the electromagnet 164 on the movable rack 163 is energized, and then the positioning magnet 165 on the paint head 7 and the electromagnet 164 on the movable rack 163 are attracted to each other, thus fixing the movable rack 163 and the paint head 7. At this time, when the transmission gear 162 reciprocates, it can cause the movable rack 163 to move back and forth in a linear manner. The reciprocating movement of the movable rack 163 can drive the paint head 7 to move synchronously, so that the flat surface of the workpiece can be sprayed with paint through the linearly moving paint head 7.
[0050] Example 2:
[0051] The intelligent spraying device with adaptive curved surface function disclosed in this embodiment is a further improvement based on the above embodiment one. Some spraying devices, when spraying workpieces, do not easily protect the coating, resulting in some coating adhering to the inner wall of the device after spraying. As the coating accumulates on the inner wall, it easily emits an irritating odor after spraying, thus affecting surrounding workers. To solve this technical problem of coating easily adhering to the inner wall of the device, this embodiment discloses the following technical content, such as... Figures 1-3 As shown;
[0052] A water tank 8 is fixed to the lower end of the interior of the heat insulation shell 1. A support plate 9 is fixedly connected to the middle of the water tank 8, and a heater 10 is installed inside the water tank 8. A second pump 11 is fixed on the left and right sides of the heat insulation shell 1. The second pump 11 is connected to the water tank 8 through a transmission pipe 12, and is also connected to the spray block 14 through a guide pipe 13. The spray block 14 is fixed to the top of the left and right sides inside the heat insulation shell 1, so that it sprays water along the side wall of the heat insulation shell 1 to form a water curtain to block the paint. Multiple nozzles are evenly distributed at equal intervals at the lower end of the spray block 14, and the spray block 14 is symmetrically arranged about the transverse central axis of the heat insulation shell 1. The surface of the heat insulation shell 1 is provided with a heat insulation layer, which is used to prevent the heat exchange between the heat insulation shell 1 and the external environment.
[0053] The working principle of this embodiment is as follows: During the painting process, the second pump 11 is turned on. The turn on of the second pump 11 enables the water source inside the water tank 8 to be transmitted to the interior of the spray block 14 through the guide pipe 13 via the transmission pipe 12. The water source is sprayed out through the nozzle at the lower end of the spray block 14 in a direction perpendicular to the heat insulation shell 1. The water source sprayed out through the nozzle at the lower end of the spray block 14 forms a water curtain, which blocks the sprayed paint and prevents the paint from being sprayed onto the inner wall of the heat insulation shell 1. A heater 10 is installed inside the water tank 8. The heater 10 can heat the water source inside the water tank 8 as needed, thereby regulating the internal temperature of the heat insulation shell 1 and keeping the internal temperature of the heat insulation shell 1 within a suitable range.
[0054] Example 3:
[0055] The intelligent spraying device with adaptive curved surface function disclosed in this embodiment is a further improvement based on the above embodiment two. Existing spraying devices, in order to facilitate the absorption of excess paint after spraying, add a water curtain to the device to adsorb the paint. However, after the paint is absorbed by the water curtain, it is not convenient to filter the paint residue. This leads to paint residue in the water source easily entering the pipe after the water pump circulates, causing pipe blockage. To solve this technical problem of paint residue easily entering the pipe, this embodiment discloses the following technical content, such as... Figure 1 , Figure 2 and Figures 5-8 As shown;
[0056] A barrier net 15 is fixed inside the left and right sides of the water tank 8 to filter paint residue from the water source. A self-cleaning structure 17 is installed above the control structure 16 to prevent paint layering inside the paint storage box 3 and to achieve reverse rinsing of the barrier net 15. The self-cleaning structure 17 consists of a main airbag 171, an air supply pipe 172, a push airbag 173, a piston rod 174, a limiting post 175, a negative pressure chamber 176, a toggle rod 177, a connecting pipe 178, and a cleaning nozzle 179. The main airbag 171 is bonded to the end of the slide rod 166. The main airbag 171 is connected to the push airbag 173 through the air supply pipe 172. The push airbag 173 is bonded between the upper end of the piston rod 174 and the inside of the limiting post 175. The limiting post 175 is fixed inside the heat insulation shell 1, and the lower end of the piston rod 174 extends into the negative pressure chamber 176. The upper end of the piston rod 174 is fixedly connected to the actuating rod 177, which extends into the paint storage box 3. The negative pressure chamber 176 is interconnected with the cleaning nozzle 179 through the connecting pipe 178. The cleaning nozzle 179 is fixed on the left and right sides inside the water tank 8 and is located below the barrier net 15. The airflow inside the main airbag 171 can enter the interior of the pushing airbag 173 through the air supply pipe 172. Both the main airbag 171 and the pushing airbag 173 are made of elastic rubber. The piston rod 174 and the actuating rod 177 are fixedly connected, and the actuating rod 177 can slide on the paint storage box 3. The limiting posts 175 are evenly distributed inside the heat insulation shell 1. The negative pressure chambers 176 inside the two limiting posts 175 located on the left side of the paint spray head 7 are connected to the cleaning spray pipe 179 on the left side of the water tank 8 via a connecting pipe 178. The negative pressure chambers 176 inside the two limiting posts 175 located on the right side of the paint spray head 7 are connected to the cleaning spray pipe 179 on the right side of the water tank 8 via a connecting pipe 178. Multiple branch spray pipes are evenly distributed at the upper end of the cleaning spray pipe 179, and the branch spray pipes at the upper end of the cleaning spray pipe 179 are perpendicular to the barrier net 15.
[0057] The working principle of this embodiment is as follows: When the sprayed paint is blocked by the water curtain, the downward flowing water contains paint residue. After the water falls into the pool 8, the paint residue in the water can be filtered by the barrier net 15. Regardless of whether the workpiece is painted on a curved or flat surface, the transmission gear 162 can cause its movable rack 163 to move back and forth during the reciprocating rotation. When the movable rack 163 moves back and forth, it can cause the upper slide rod 166 to move back and forth on the support block 167. When the slide rod 166 moves, the main airbag 171 on it and the support block 167 move back and forth. After block 167 contacts and is compressed, the airflow inside its main airbag 171 can enter the interior of the push airbag 173 through the air supply pipe 172. After the push airbag 173 inflates, it causes its piston rod 174 to move upward inside the limiting post 175. When the slide rod 166 moves, the main airbag 171 on it disengages from the support block 167, and the main airbag 171 resets. At this time, the airflow inside the push airbag 173 flows back to the interior of the main airbag 171 through the air supply pipe 172. Then, the push airbag 173 contracts and pulls the piston rod 174 downward. The piston rod 174 reciprocates up and down inside the limiting post 175. This reciprocating movement of the piston rod 174 allows the actuating rod 177, which is fixedly connected to its upper end, to move synchronously inside the paint storage box 3. The reciprocating movement of the actuating rod 177 improves the flowability of the paint inside the paint storage box 3, preventing the paint from separating due to prolonged storage. Simultaneously, when the lower end of the piston rod 174 moves upward inside the negative pressure chamber 176, a negative pressure is created inside the negative pressure chamber 176. This negative pressure is then transmitted through the connecting pipe 178 and the cleaning spray pipe 1. 79 draws water from inside the water tank 8. When the lower end of the piston rod 174 moves downward inside the negative pressure chamber 176, it can squeeze the water drawn from inside the cleaning nozzle 179 upward. The water squeezed upward by the cleaning nozzle 179 can be used to backwash the filter holes on the barrier screen 15, preventing the filter holes on the barrier screen 15 from being blocked by paint residue. At the same time, when the cleaning nozzle 179 is performing water intake and drainage operations, it can improve the flow of water inside the water tank 8. The increased flow of water can increase the heating efficiency of the heater 10 on the water source.
