Description

Technical Field

[0001] This invention relates to a ceramic coating spraying device capable of operating at multiple free angles, belonging to the field of ceramic coating spraying processing. Background Technology

[0002] Ceramic coatings, due to their excellent properties such as high hardness, wear resistance, high temperature resistance, and corrosion resistance, are widely used for surface protection and functional modification of mechanical parts, electronic components, and aerospace structural parts. Spray coating, as an important ceramic coating preparation process, has become one of the most widely used coating methods in industrial production due to its convenient operation, high film-forming efficiency, and applicability to complex-shaped substrates.

[0003] Currently, most existing ceramic coating spraying equipment adopts a structure of linear conveyor belt combined with fixed spray guns. After the material is transported to the spraying station by the conveyor belt, the fixed spray guns spray the material surface from top to bottom or from the side. However, there are obvious shortcomings in practical applications. First, the spraying direction of the fixed spray gun is limited, making it difficult to achieve uniform coverage of the multiple sides and irregular surfaces of the material. The problem of spraying dead corners is particularly prominent, resulting in uneven coating thickness distribution, which seriously affects the protective performance and bonding quality of the coating. Second, although some devices can expand the spraying range by adding multiple sets of spray guns or driving the spray guns to make reciprocating linear motion, this often leads to more complex equipment structure and increased manufacturing costs. Moreover, the overlapping areas between multiple spray guns are prone to overspraying or underspraying, making control difficult.

[0004] Therefore, there is an urgent need to improve the ceramic coating spraying device that can operate at multiple free angles in order to solve the above-mentioned problems. Summary of the Invention

[0005] The purpose of this invention is to provide a ceramic coating spraying device that can operate at multiple free angles. Based on the rotation of the square conveyor belt, the sprayer, which is fixedly connected to the extension arc rod, can revolve around the central axis, thereby further improving the coating quality of the material. Moreover, the rotation of the square conveyor belt and the sprayer is driven by only one drive device, which not only reduces energy consumption, but also reduces the load and maintenance cost of the drive device.

[0006] To achieve the above objectives, the main technical solutions adopted by the present invention include: A ceramic coating spraying device capable of operating at multiple free angles includes a first conveyor belt and a second conveyor belt for material conveying, and a spraying chamber located between the first conveyor belt and the second conveyor belt. Inside the spraying chamber, a square conveyor belt is arranged between the first conveyor belt and the second conveyor belt. The square conveyor belt contains a liquid storage tank and a square conveyor belt drive roller. The square conveyor belt drive roller is used for the transmission of materials by the square conveyor belt, and the liquid storage tank is used not only for the rigid support of the square conveyor belt as a whole, but also for the storage of liquid. A forward and reverse motor is installed below the square conveyor belt. A transmission cylinder is fixedly installed at the output end of the forward and reverse motor. The transmission cylinder extends into the liquid storage tank and is fixedly connected to the liquid storage tank. A fixed bevel gear is fixedly installed on the lower half of the transmission cylinder. The fixed bevel gear is meshed with a rotating bevel gear that is rotatably connected to the transmission cylinder through a connecting bevel gear. An extension arc rod that is rotatably connected to the transmission cylinder is fixedly installed on the upper side of the rotating bevel gear. A sprayer for spraying materials is fixedly installed at the end of the extension arc rod away from the rotating bevel gear.

[0007] Preferably, the upper half of the transmission cylinder has multiple liquid inlet slots, and each liquid inlet slot is located inside the liquid storage tank, while the lower half of the transmission cylinder has a liquid outlet slot.

[0008] Preferably, a buffer cavity is provided inside the extension arc rod, the liquid outlet groove is located inside the buffer cavity, and a liquid delivery pipe for liquid delivery is also fixedly installed on the extension arc rod. One end of the liquid delivery pipe is connected to the inside of the delivery buffer cavity, and the other end of the liquid delivery pipe is connected to the inside of the sprayer. A sealing rubber ring is fitted on the upper side of the connection between the transmission cylinder and the extension arc rod, and the sealing rubber ring is used to seal between the two.

[0009] Preferably, an outer frame tube is fixedly provided on the upper side of the forward and reverse motor. The outer frame tube is used to protect the fixed bevel gear, the connecting bevel gear, and the rotating bevel gear. The connecting surface of the rotating bevel gear and the extended arc rod is located outside the outer frame tube and is rotatably connected to the outer frame tube. A forward and reverse motor bracket is fixedly installed on the outside of the outer frame tube. The forward and reverse motor bracket is used to support the height and position of the forward and reverse motor.

[0010] Preferably, one of the square conveyor belt drive rollers is provided with a protective shell on one side, and a drive roller motor is fixedly installed inside the protective shell. The output end of the drive roller motor extends to the outside of the protective shell and is fixedly connected to one end of one of the square conveyor belt drive rollers. The protective shell is also located inside the square conveyor belt and is wrapped around it, and the diameter of the protective shell is the same as that of the drive roller of the square conveyor belt.

[0011] Preferably, a sealing plate is fixedly installed on both sides of the liquid storage tank opening, and a baffle is fixedly installed on the other side of the sealing plate. Both baffles are in contact with one end of the square conveyor belt drive roller, and one end of the protective shell is fixedly connected to one of the baffles on one side. One side of the sealing plate has an injection hole, which extends to the outside through the sealing plate and the baffle. A threaded plug is threadedly connected to one side of the injection hole.

[0012] Preferably, both the first conveyor belt and the second conveyor belt are provided with supports, and both supports are provided with rigid support plates for providing rigid support for the first conveyor belt and the second conveyor belt. Both supports are also provided with drive motors for driving the first conveyor belt and the second conveyor belt.

[0013] Preferably, the first conveyor belt is positioned higher than the square conveyor belt, and a gap is left between the first conveyor belt and the square conveyor belt to allow the extension arc rod to rotate. An inclined support plate fixedly connected to the support is provided on the side of the first conveyor belt near the square conveyor belt. The inclined support plate is inclined towards the side of the square conveyor belt. Several connectors are fixedly provided on the side of the inclined support plate near the square conveyor belt. Each connector is rotatably connected to a compensating rotating rod at the end away from the inclined support plate. Multiple rollers for assisting material movement are rotatably provided on the compensating rotating rod. A return spring can be added to the connector and the rotating node of the compensation rod, so that the compensation rod can automatically reset when no force is applied.

[0014] Preferably, multiple flexible plastic diaphragms are provided in the openings on both sides of the spraying chamber. The upper ends of the flexible plastic diaphragms are fixedly connected to the spraying chamber. A ventilation groove is provided inside the spraying chamber. A fan is rotatably installed in the ventilation groove via an installation rod. A ventilation pipe communicating with the inside of the spraying chamber is fixedly installed on the outside of the ventilation groove.

[0015] Preferably, an infrared detector is fixedly installed inside the spraying chamber. The infrared detector is used for object detection. The infrared detector is electrically connected to the drive motor, the transmission roller motor and the forward and reverse motor respectively through a signal device. The forward and reverse motor is electrically connected to the pump body inside the sprayer through a signal device.

[0016] This invention has at least the following beneficial effects: When the forward and reverse motors start, they drive the liquid storage tank to rotate via the transmission cylinder. Since the square conveyor belt wraps around the liquid storage tank, the square conveyor belt rotates accordingly, enabling multi-directional spraying of the material on the square conveyor belt. Based on the rotation of the square conveyor belt, the sprayer, which is fixedly connected to the extension arc rod, can revolve, thereby further improving the spraying effect on the material. Moreover, the rotation of the square conveyor belt and the sprayer is driven by only one drive device, which not only reduces energy consumption but also reduces the load and maintenance costs of the forward and reverse motors.

[0017] The liquid stored inside the storage tank can flow into the buffer chamber through multiple liquid inlet slots opened in the upper part of the transmission cylinder. The liquid can then be supplied to the sprayer through the liquid delivery pipe connected to the buffer chamber. Since the length and position of the liquid delivery pipe are fixed, the liquid delivery pipe will not affect the rotation of the sprayer when the sprayer is rotating, thus enabling the sprayer to spray the material.

[0018] The two separate supports not only support the first and second conveyor belts, but also enhance the rigidity of the bearing surfaces of the first and second conveyor belts through the rigid support plate, so that both the first and second conveyor belts can bear the weight of the material. At the same time, the power source for the first and second conveyor belts comes from two separate drive motors, which enables the first and second conveyor belts to convey the material.

[0019] Multiple compensating rotating rods are installed at the end of the first conveyor belt near the square conveyor belt via inclined support plates. The length of the compensating rotating rods is used to compensate for the material's shortcomings. At the same time, the rollers provide sliding assistance for the material, allowing it to be smoothly conveyed onto the square conveyor belt for spraying. Attached Figure Description

[0022] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0023] like Figures 1-10 As shown, the ceramic coating spraying device capable of operating at multiple free angles provided in this embodiment includes a first conveyor belt 1 and a second conveyor belt 2 for material conveying, and a spraying chamber 4 located between the first conveyor belt 1 and the second conveyor belt 2. Inside the spraying chamber 4, a square conveyor belt 8 is arranged between the first conveyor belt 1 and the second conveyor belt 2. Inside the square conveyor belt 8, there is a liquid storage tank 802 and a square conveyor belt drive roller 801. The square conveyor belt drive roller 801 is used for the transmission of materials by the square conveyor belt 8. The liquid storage tank 802 is not only used for the rigid support of the square conveyor belt 8 as a whole, but also for the storage of liquid. The first conveyor belt 1, the second conveyor belt 2 and the square conveyor belt 8 can all convey materials, so that multiple arranged materials can be sprayed in sequence. In order to enable the material to be sprayed from multiple directions, a forward and reverse motor 13 is installed below the square conveyor belt 8. A transmission cylinder 131 is fixedly installed at the output end of the forward and reverse motor 13. The transmission cylinder 131 extends into the liquid storage tank 802 and is fixedly connected to the liquid storage tank 802. When the forward and reverse motor 13 is started, it can drive the liquid storage tank 802 to rotate through the transmission cylinder 131. Since the square conveyor belt 8 wraps around the liquid storage tank 802, the square conveyor belt 8 will rotate accordingly, thereby enabling multi-directional spraying of the material located on the square conveyor belt 8. To further improve the spraying effect, a fixed bevel gear 16 is fixedly installed on the lower half of the transmission cylinder 131. The fixed bevel gear 16 is meshed with a rotating bevel gear 17, which is rotatably connected to the transmission cylinder 131, through a connecting bevel gear 18. An extension arc rod 10, which is rotatably connected to the transmission cylinder 131, is fixedly installed on the upper side of the rotating bevel gear 17. A sprayer 9 for spraying materials is fixedly installed at the end of the extension arc rod 10 away from the rotating bevel gear 17. When the transmission cylinder 131 rotates, the fixed bevel gear 16, which is fixedly connected to it, will rotate accordingly. At this time, the fixed bevel gear 16 can drive the rotating bevel gear 17 to rotate through the action of the connecting bevel gear 18. Since the rotating bevel gear 17 and the transmission cylinder 131 are rotatably connected, the meshing of the three will not cause jamming. At the same time, during this process... The rotating bevel gear 17 rotates in the opposite direction to the connecting bevel gear 18. Thus, the extended arc rod 10, which is fixedly connected to the upper side of the rotating bevel gear 17, can rotate in the opposite direction to the square conveyor belt 8. In this way, the sprayer 9, which is fixedly connected to the extended arc rod 10, can revolve around the square conveyor belt 8 while the square conveyor belt 8 rotates on its own axis. The sum of 180° in the two rotation directions is equal to the spraying of one rotation of the material, which can further improve the spraying effect on the material. At the same time, the extended arc rod 10 has a certain curvature at the corner, so that when the extended arc rod 10 rotates, it will not come into contact with the square conveyor belt 8, so that the sprayer 9 can be used smoothly with the square conveyor belt 8. Moreover, the connection between the extended arc rod 10 and the transmission cylinder 131 is located at the center point of the square conveyor belt 8, so that the rotation points of the two are the same. Moreover, the rotation of the square conveyor belt 8 and the sprayer 9 is driven by only one drive device, which not only reduces energy consumption, but also reduces the load and maintenance cost of the forward and reverse motors 13. It should be noted that, through the system settings, the reciprocating rotation amplitude of the forward and reverse motor 13 is only 180° (the reciprocating rotation direction of the forward and reverse motor 13 is: clockwise-counterclockwise, clockwise-counterclockwise, the square conveyor belt 8 is in the same reciprocating rotation direction as the forward and reverse motor 13, while the sprayer 9 is in the opposite direction to the reciprocating rotation direction of the forward and reverse motor 13). At the same time, the operator can set the number of reciprocating rotations of the forward and reverse motor 13 through the system to change the spraying effect. It should be noted that a concave ring is provided on the transmission cylinder 131, which allows the rotating bevel gear 17 to be rotatably connected to the transmission cylinder 131 through the concave ring without displacement.

[0024] To supply liquid to the sprayer 9, the upper half of the transmission cylinder 131 has multiple liquid inlet slots 132, each located inside the liquid storage tank 802. The lower half of the transmission cylinder 131 has a liquid outlet slot 133. A buffer chamber 121 is located inside the extension arc rod 10, and the liquid outlet slot 133 is located inside the buffer chamber 121. A liquid delivery pipe 12 for liquid transport is also fixedly installed on the extension arc rod 10, with one end of the pipe connected to the inside of the delivery buffer chamber 121. The other end of the liquid pipe 12 is connected to the inside of the sprayer 9. The liquid stored in the liquid storage tank 802 can flow into the buffer chamber 121 through the multiple liquid inlet grooves 132 opened in the upper part of the transmission cylinder 131. The liquid can be supplied to the inside of the sprayer 9 through the liquid delivery pipe 12 connected to the buffer chamber 121. Since the length and position of the liquid delivery pipe 12 are fixed, the liquid delivery pipe 12 will not affect the rotation of the sprayer 9 when the sprayer 9 is rotating, so that the sprayer 9 can spray the material. In addition, a sealing rubber ring 134 is fitted on the upper side of the connection between the transmission cylinder 131 and the extension arc rod 10. The sealing rubber ring 134 is used for sealing between the two. Adding a sealing rubber ring 134 to the connection between the transmission cylinder 131 and the extension arc rod 10 can effectively prevent liquid from seeping out through the connection gap. Furthermore, sealing plates 111 are fixedly installed on both sides of the liquid storage tank 802, and baffles 11 are fixedly installed on the other side of the sealing plates 111. Both baffles 11 are in contact with one end of the square conveyor belt drive roller 801. One side of the sealing plate 111 has an injection hole 112. The injection hole 112 extends to the outside through the sealing plate 111 and the baffle 11. A threaded plug 113 is threadedly connected to one side of the injection hole 112. The sealing plate 111 can seal the openings on both sides of the liquid storage tank 802 to prevent liquid from leaking out. At the same time, it provides protection for the two square conveyor belt drive rollers 801. The baffle 11 installed on one side of the sealing plate 111 can seal both sides of the square conveyor belt 8. When it is necessary to add liquid to the liquid storage tank 802, the operator can manually unscrew the threaded plug 113 and then connect the delivery pipe to the inside of the liquid storage tank 802 through the injection hole 112 to supply oil to the inside of the liquid storage tank 802. It should be noted that, in order to ensure the rigidity and strength of the transmission cylinder 131, the mass of the transmission cylinder 131 can be increased by using rigidity strength, so that the transmission cylinder 131 can complete the function of the transmission part.

[0025] In order to protect the transmission parts, such as Figure 6 , Figure 7As shown, an outer frame tube 15 is fixedly installed on the upper side of the forward and reverse motor 13. The outer frame tube 15 is used to protect the fixed bevel gear 16, the connecting bevel gear 18, and the rotating bevel gear 17. The connecting surface of the rotating bevel gear 17 and the extension arc rod 10 is located outside the outer frame tube 15 and is rotatably connected to the outer frame tube 15. The outer frame tube 15 installed on the upper side of the forward and reverse motor 13 can protect the fixed bevel gear 16, the rotating bevel gear 17, and the connecting bevel gear 18, which can prevent the transmission efficiency of the transmission part from decreasing due to external fly ash impurities and other factors. At the same time, the connecting surface of the rotating bevel gear 17 and the extension arc rod 10 is outside the outer frame tube 15, so it will not affect the rotation of the sprayer 9. Furthermore, one end of the connecting bevel gear 18 can be rotatably connected to the inner wall of the outer frame tube 15, thereby limiting the position and height of the connecting bevel gear 18. In addition, a forward and reverse motor bracket 14 is fixedly installed on the outside of the outer frame tube 15. The forward and reverse motor bracket 14 is used to support the height and position of the forward and reverse motor 13. The forward and reverse motor bracket 14 can support the forward and reverse motor 13 so that the forward and reverse motor 13 can work at the specified height position.

[0026] Furthermore, such as Figure 9 As shown, a protective shell 19 is provided on one side of one of the square conveyor belt drive rollers 801. A drive roller motor 191 is fixedly installed inside the protective shell 19. The output end of the drive roller motor 191 extends to the outside of the protective shell 19 and is fixedly connected to one end of one of the square conveyor belt drive rollers 801. The drive roller motor 191 can drive one of the square conveyor belt drive rollers 801 to rotate, so that the square conveyor belt drive roller 801 wrapped by the square conveyor belt 8 can provide power to the square conveyor belt 8, thereby enabling the square conveyor belt 8 to perform the conveying effect. In addition, the protective shell 19 is also located inside the square conveyor belt 8, and the diameter of the protective shell 19 is the same as that of the square conveyor belt drive roller 801. One end of the protective shell 19 is fixedly connected to one of the side baffles 11. The protective shell 19 can not only provide position fixation and support for the drive roller motor 191, but also work with the square conveyor belt drive roller 801 to prevent the surface of the square conveyor belt 8 from being uneven. It should be noted that the gap between the drive roller motor 191 and the protective shell 19 and the connected square conveyor belt drive roller 801 is small, so that a large area of ​​the connection part at the output end of the drive roller motor 191 will not collapse.

[0027] Furthermore, such as Figures 1-5As shown, both the first conveyor belt 1 and the second conveyor belt 2 are equipped with supports 3. Each support 3 has a rigid support plate 302 providing rigid support for the first conveyor belt 1 and the second conveyor belt 2. Both supports 3 also have drive motors 301 for driving the first conveyor belt 1 and the second conveyor belt 2. The first conveyor belt 1 is positioned higher than the square conveyor belt 8, and a gap is left between the first conveyor belt 1 and the square conveyor belt 8 to allow the extension arc rod 10 to rotate. An inclined support plate 101, fixedly connected to the support 3, is provided on the side of the first conveyor belt 1 closest to the square conveyor belt 8. The inclined support plate 101 is inclined towards the side of the square conveyor belt 8 and fixed on the side closest to the square conveyor belt 8. The system is equipped with several connectors 103, each of which is rotatably connected to a compensating rod 102 at the end away from the inclined support plate 101. Multiple rollers 104 for assisting material movement are rotatably mounted on the compensating rod 102. The two separate supports 3 not only support the first conveyor belt 1 and the second conveyor belt 2, but also enhance the rigidity of the force-bearing surfaces of the first conveyor belt 1 and the second conveyor belt 2 through the rigid support plate 302, so that both the first conveyor belt 1 and the second conveyor belt 2 can bear the weight of the material. At the same time, the power source of the first conveyor belt 1 and the second conveyor belt 2 comes from two separate drive motors 301, thereby enabling the first conveyor belt 1 and the second conveyor belt 2 to convey the material. In addition, a certain gap is left between the first conveyor belt 1 and the square conveyor belt 8 to allow the sprayer 9 to rotate. To compensate for the gap between the first conveyor belt 1 and the square conveyor belt 8, such as... Figure 9 As shown, multiple compensating rotating rods 102 are set at the end of the first conveyor belt 1 near the square conveyor belt 8 via inclined support plate 101. The length of the compensating rotating rods 102 is used to compensate for the material's weight. At the same time, the rollers 104 can also provide sliding assistance for the material, so that the material can be smoothly conveyed to the square conveyor belt 8 for spraying. In order to cooperate with the multiple inclined compensating rotating rods 102, the height of the first conveyor belt 1 is higher than that of the square conveyor belt 8. In order to reset the compensating rod 102 when it is not under force, a reset spring can be added to the connector 103 and the rotating node of the compensating rod 102 so that the compensating rod 102 can automatically reset when it is not under force. Furthermore, multiple soft plastic diaphragms 5 are installed in the openings on both sides of the spray chamber 4. The upper end of the soft plastic diaphragm 5 is fixedly connected to the spray chamber 4. A ventilation groove 401 is opened inside the spray chamber 4. A fan 7 is rotatably installed in the ventilation groove 401 via an installation rod. A ventilation pipe 6 communicating with the inside of the spray chamber 4 is fixedly installed on the outside of the ventilation groove 401. The installation of the soft plastic diaphragm 5 can prevent paint from splashing to the outside of the spray chamber 4. To reduce odor, fan 7 is always on, drawing air out of the spray booth 4 through vent pipe 6.

[0028] An infrared detector 402 is fixedly installed inside the spraying chamber 4. The infrared detector 402 is used to detect objects. The infrared detector 402 is electrically connected to the drive motor 301, the transmission roller motor 191 and the forward and reverse motor 13 through a signal device. The forward and reverse motor 13 is electrically connected to the pump body inside the sprayer 9 through a signal device. When the infrared detector 402 detects material, it can control the drive motor 301 and the transmission roller motor 191 to shut down through the signal device, so that the material can stay on the square conveyor belt 8. When the forward and reverse motor 13 completes the set rotation, the drive motor 301 and the transmission roller motor 191 will automatically turn on to transport the material. In addition, the infrared detector 402 is tilted downwards and its detection point is located at the center of the square conveyor belt 8. Therefore, when the material is conveyed to the center of the square conveyor belt 8, the infrared detector 402 can send a switch signal to the aforementioned drive equipment.

[0029] like Figures 1-10 As shown, the ceramic coating spraying device capable of operating at multiple free angles provided in this embodiment includes the following steps: Step 1: Material conveying. When the material is conveyed onto the first conveyor belt 1, the drive motor 301 can drive the first conveyor belt 1 to convey the material into the spraying chamber 4. Step 2: When the material enters the spraying chamber 4, the infrared detector 402 will detect the material and then use the signal device to control the rotation of the drive motor 301 and the transmission roller motor 191, so that the drive motor 301 and the transmission roller motor 191 stop rotating, thereby stopping the conveyor belt from conveying. Step 3: When the infrared detector 402 detects the material, it will drive the forward and reverse motor 13 to start through the signal device, so that the forward and reverse motor 13 can drive the square conveyor belt 8 and the sprayer 9 to rotate. Step 4: When the forward and reverse motor 13 receives the start command, it will drive the pump inside the sprayer 9 through the signal device, so that the sprayer 9 can spray the material. Step 5: After the spraying is completed, the signal device can send a start command to the signal receiver of the drive motor 301 and the transmission roller motor 191, so that the drive motor 301 and the transmission roller motor 191 can continue to perform the conveying function.
