Description

Technical Field

[0001] The invention relates to a ceramic coating spraying system, belonging to the technical field of spraying. Background Art

[0002] The spraying process uses a spray gun to disperse the paint into a uniform, fine mist using pressure or centrifugal force, and then applies it to the surface of the object being coated. Water-based, high-temperature-resistant, flexible ceramic coatings are a commonly used coating. Current ceramic coating spraying systems primarily consist of paint preparation equipment, conveying equipment, multiple sets of placement fixtures mounted on the movable portion of the conveying equipment, a spraying device located on the fixed portion of the conveying equipment and connected to the paint preparation equipment, and an air-drying device located behind the spraying device and mounted on the fixed portion of the conveying equipment. When the system is in operation, the coating preparation equipment first completes the preparation of the water-based high-temperature resistant flexible ceramic coating; after the coating is prepared, the workpiece is mounted on the placement fixture and transported to the spraying equipment via the conveying equipment for spraying; after the spraying is completed, the conveying equipment is used again to transfer the workpiece to the air-drying equipment to complete the coating curing; finally, the cured workpiece is removed from the air-drying equipment by the conveying equipment, thereby realizing the linear and continuous transportation of the workpiece between different stations. To ensure the smooth flow of the workpiece between the spraying and air-drying stations, the spraying equipment and the air-drying equipment are in a connected state. However, since both devices generate airflow during operation, and the airflow affects each other between the devices, the probability of interference from adjacent processes when operating at different stations increases significantly, which in turn increases the risk of defects in the sprayed workpiece, seriously affecting the spraying effect and quality. In addition, this linear system layout also has the problem of large equipment installation space. Summary of the Invention

The exhaust device is used to generate airflow. The exhaust device can be a fan 5. The inner wall surface of the right part of the outer cover 1 is recessed outward to form a second groove 19 located between the two adjacent rotating plates 6 on the right side. The second groove 19 provides installation space for components such as the second main pipe 193, and the second main pipe 193 is set on the bottom end of the second groove 19. The second main pipe 193 provides a mounting carrier for the second vertical pipe 191, and then multiple second vertical pipes 191 are equidistantly connected and installed on the upper end of the second main pipe 193.

Gas is extracted from the air-drying cavity of the outer cover 1 through the suction pipe 192. A first cover 51, which is connected to the inlet 11 of the air extraction device and has a conical cross-section with a narrow front and a wide rear, is installed on the front end of the air extraction device. The first pipe 52 is connected to the air extraction device through the first cover 51, and the other end of the first pipe 52 passes through the outer cover 1 and is connected to the second main pipe 193. The first pipe 52 is connected and arranged on the front end of the first cover 51. The second main pipe 193 is connected to the first cover 51 through the first pipe 52. Then, the air pipe 13 located between the two adjacent rotating plates 6 on the right side is connected and arranged on the upper end of the outer cover 1. Air is supplied to the air drying cavity of the outer cover 1 through the air pipe 13. A dustproof net 14 is installed on the upper end of the air pipe 13. The dustproof net 14 realizes the dustproof function. A collecting cylinder 35 having a conical cross-section that is wide at the top and narrow at the bottom is installed on the top inner side of the frame 3, and the upper end of the collecting cylinder 35 is connected to the first through-slot 17. Excess ceramic coating is collected through the collecting cylinder 35. The upper end surface of the frame 3 is recessed downward to form a first through-slot 17. The spraying cavity of the outer cover 1 is connected to the collecting cylinder 35 through the first through-slot 17. The upper end surface of the frame 3 is recessed downward to form a second through-slot 161 that is connected to the upper end of the collecting cylinder 35 and is located on the right side of the first through-slot 17. The impurity removal cavity of the outer cover 1 is connected to the collecting cylinder 35 through the second through-slot 161.

[0020] During use, the raw materials of the water-based high-temperature resistant flexible ceramic coating are first put into the stirring tank 32, and then the second motor 34 is started to drive the agitator to rotate, thereby stirring the raw materials of the water-based high-temperature resistant flexible ceramic coating in the stirring tank 32. At the same time, a curing agent is added into the stirring tank 32, so that the raw materials of the water-based high-temperature resistant flexible ceramic coating and the curing agent are evenly mixed, and then the water-based high-temperature resistant flexible ceramic coating is prepared in the stirring tank 32.

[0021] After the water-based high-temperature resistant flexible ceramic coating is prepared, the workpiece to be sprayed is first conveyed to the feeding position by the conveyor 21 on the left side. Five rotating plates 6 are equidistantly arranged on the outer end of the rotating shaft 7 inside the outer cover 1, so that the internal space of the outer cover 1 is divided into five cavities by the five rotating plates 6. The five cavities are respectively a feeding cavity connected to the inlet 11, a spraying cavity, a decontamination cavity, an air-drying cavity, and a discharging cavity connected to the outlet 12. Then, a person takes the workpiece to be sprayed from the conveyor 21 and places the workpiece to be sprayed into the feeding cavity inside the outer cover 1 through the inlet 11. Then, the corresponding pressing plate 46 is pushed upward to compress the corresponding elastic member 44, causing the elastic member 44 to generate elastic force, and the workpiece to be sprayed is placed on the upper end of the bracket 41. Then, the pressing plate 46 is released, and under the elastic force of the elastic member 44, the pressing plate 46 moves downward and contacts the upper end of the workpiece to be sprayed in a squeeze manner, thereby quickly clamping the workpiece to be sprayed. Then, the first motor 15 is started to drive the rotating shaft 7 to rotate, thereby rotating the five rotating plates 6, the five mounting plates 4, the five brackets 41 and other components by a designed angle, so that the clamped workpiece to be sprayed is rotated into the spraying chamber. At this time, a new workpiece to be sprayed is clamped and mounted in the new feed chamber. At the same time, the pump 31 is started to extract the ceramic coating prepared in the stirring tank 32 and transport the extracted ceramic coating to the first main pipe 181. The ceramic coating in the first main pipe 181 is then diverted into multiple first vertical pipes 182. The ceramic coating in the first vertical pipe 182 is then diverted into multiple atomizing nozzles 183, and the atomized ceramic coating is sprayed toward the surface of the clamped workpiece to be sprayed through the multiple atomizing nozzles 183, thereby performing a spraying operation on the clamped workpiece. During the spraying process, excess ceramic coating will fall into the collecting barrel 35 through the first through groove 17, thereby completing the collection of the ceramic coating. When the spraying is completed, the first motor 15 and the rotating shaft 7 and other components are used again to rotate the sprayed workpiece into the impurity removal chamber and stop spraying for a period of time. At this time, the newly clamped workpiece to be sprayed enters the spraying chamber and is sprayed. During the spraying time, the atomized ceramic coating floating in the chamber falls and enters the collecting barrel 35 through the second through groove 161, thereby achieving impurity removal treatment for the environment in which the workpiece is located after spraying, effectively reducing the probability of impurities adhering to the outer surface of the workpiece during the subsequent air-drying process, effectively reducing the probability of defects such as bumps on the surface of the workpiece after air-drying, and effectively ensuring the spraying effect and quality. After the spraying time is up, the first motor 15 and the rotating shaft 7 and other components are used again to rotate the cleaned workpiece into the air-drying chamber, and then the fan 5 is started. The fan 5 will extract the gas in the first cover 51, so that a negative pressure is formed in the first cover 51. Under the action of the negative pressure, the gas in the air-drying chamber enters the first cover 51 along the multiple suction pipes 192, the multiple second vertical pipes 191, the second main pipe 193 and the first pipe 52. At the same time, the external air enters the air-drying chamber through the air pipe 13, thereby forming an airflow in the air-drying chamber. The formed airflow will flow on the outer surface of the cleaned workpiece, so that the ceramic coating sprayed on the surface of the workpiece is solidified, and the workpiece spraying operation is completed. Then, the first motor 15 and the rotating shaft 7 and other components are used to rotate the solidified workpiece into the discharge cavity. Then, another person disassembles and removes the workpiece in the discharge cavity through the outlet 12, and places the removed workpiece on the conveyor 21 on the right. The conveyor 21 on the right is used to convey the removed workpiece out, thereby realizing a circular continuous hidden spraying operation on the workpiece in the five cavities formed by the five rotating plates 6 in the outer cover 1, effectively reducing the probability of interference from adjacent processes when operating at different workstations, effectively reducing the probability of defects in the sprayed workpiece, effectively ensuring the spraying effect and quality, and reducing the space required for the layout and installation of the overall system.

[0022] Example 2: This machining system utilizes an outer housing 1, a rotating shaft 7, and five rotating plates 6 to create five functional chambers arranged in a circular configuration. Driven by a first motor 15, the workpiece is continuously and concealedly transported in a circular motion, completing the following processes: clamping and loading, spraying, impurity removal, air drying, and material removal. This design effectively reduces the risk of interference between different process steps. During the impurity removal process, the system primarily utilizes the gravitational settling properties of floating impurities. However, in actual operation, it was found that impurities were prone to secondary floating during workpiece transportation, significantly increasing the probability of impurities reattaching to the workpiece surface. Furthermore, the time required for impurity removal and the fluidity of the ceramic coating sprayed on the workpiece surface significantly increase the risk of flow marks forming on the workpiece surface during the impurity removal process.

[0023] In order to solve the above problems, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 7 and Figure 8As shown, a second cover 53, which is connected to the outlet 12 of the air extraction device and has a tapered cross-section with a wide front, is installed on the rear end of the air extraction device. The second cover 53 allows the second pipe 54 to communicate with the air extraction device. The filter 16 is installed in the second through-slot 161. The filter 16 prevents the material in the collection cylinder 35 from entering the outer cover 1. A conical cylinder 552, which has a tapered cross-section with a wide top and a narrow bottom, is then set in the second through-slot 161. The conical cylinder 552 provides a mounting support for the blocking plate 55. A second tube 54, the other end of which passes through the frame 3 and is in communication with the lower end of the conical cylinder 552, is connected and arranged on the rear end of the second cover 53. The conical cylinder 552 and the second cover 53 are connected through the second tube 54. A blocking plate 55 located in the second through groove 161 is set on the upper end of the conical cylinder 552. The mouth of the conical cylinder 552 is blocked by the blocking plate 55. A plurality of through holes 551 penetrating the blocking plate 55 are formed on the upper end surface of the blocking plate 55. The plurality of through holes 551 are arranged in a conical structure that is narrow at the bottom and wide at the top. The plurality of through holes 551 are used in combination to spray gas into the outer cover 1. Five straight cylinders 47 are respectively arranged on the upper ends of the five pressure plates 46. The straight cylinders 47 provide a mounting carrier for the guide cylinder 42, and five guide cylinders 42 with a conical cross-section that is narrow at the top and wide at the bottom and located on the lower side of the fixed plate 43 are respectively installed on the upper ends of the five straight cylinders 47. The gas sprayed from the through hole 551 is guided by the guide cylinder 42, and a plurality of auxiliary rods 421 are equidistantly arranged on the outer edge of the guide cylinder 42. The auxiliary rods 421 facilitate the up and down movement of the guide cylinder 42.

[0024] During use, the second motor 34, the stirring tank 32 and the stirrer are first used to prepare the water-based high-temperature resistant flexible ceramic coating. After the water-based high-temperature resistant flexible ceramic coating is prepared, a conveyor 21 is first used to convey the workpiece to be sprayed to the feeding position, and five rotating plates 6 located in the outer cover 1 are equidistantly arranged on the outer end of the rotating shaft 7, so that the internal space of the outer cover 1 is divided into five cavities by the five rotating plates 6. The five cavities are respectively a feeding cavity connected to the inlet 11, a spraying cavity, a decontamination cavity, an air-drying cavity and a discharging cavity connected to the outlet 12. Then, the workpiece to be sprayed is placed into the feeding cavity in the outer cover 1 through the inlet 11; The pressure plate 46, elastic member 44 and bracket 41 are then used to quickly clamp the workpiece to be sprayed. The first motor 15, rotating shaft 7, five rotating plates 6, five mounting plates 4 and five brackets 41 are then used to rotate the clamped workpiece to be sprayed into the spray chamber. The pump 31, first manifold 181, multiple first vertical pipes 182 and multiple atomizing nozzles 183 are then used to atomize the ceramic coating prepared in the mixing tank 32 and spray it onto the surface of the clamped workpiece to be sprayed, thereby performing a spraying operation on the clamped workpiece. During the spraying process, the ceramic coating is collected through the first through groove 17 and the collecting cylinder 35. When the spraying is completed, the first motor 15 and the rotating shaft 7 and other components are used again to rotate the sprayed workpiece into the impurity removal chamber and stop spraying for a period of time. At this time, the fan 5, the first cover 51, the multiple suction pipes 192, the multiple second vertical pipes 191, the second main pipe 193 and the first pipe 52 are used to extract the gas in the air-drying chamber in the outer cover 1, and the extracted gas enters the conical cylinder 552 along the second cover 53 and the second pipe 54, and flows obliquely upward through the multiple through holes 551, thereby blowing out the floating impurities close to the workpiece. Then the flowing gas enters the guide cylinder 42 and flows obliquely downward under the guidance of the guide cylinder 42, thereby exerting a downward force on the floating impurities in the impurity removal chamber, thereby assisting the falling of the floating impurities in the impurity removal chamber, and then the falling impurities enter the collecting cylinder 35 through the second through groove 161; It assists the impurity removal operation, effectively reduces the probability of secondary floating of impurities due to the rotation of the rotating plate 6 and other components, and pre-treats the ceramic coating sprayed on the workpiece surface, effectively reduces the probability of flow marks on the workpiece surface, and effectively ensures the spraying effect and quality; Then, the first motor 15 and the rotating shaft 7 and other components are used to rotate the cleaned workpiece into the air-drying chamber, and then the fan 5, the first cover 51, multiple suction pipes 192, multiple second vertical pipes 191, the second main pipe 193, the first pipe 52 and the air pipe 13 are used to form an airflow in the air-drying chamber. The formed airflow will flow on the outer surface of the cleaned workpiece, so that the ceramic coating sprayed on the surface of the workpiece is solidified, and then the workpiece spraying operation is completed. Then, the first motor 15 and the rotating shaft 7 and other components are used to rotate the solidified workpiece into the discharge chamber, and then the workpiece in the discharge chamber is disassembled and removed through the outlet 12, and the removed workpiece is placed on the conveyor 21 on the right, and the conveyor 21 on the right is used to convey the removed workpiece out.

[0025] Example three: The system is based on a circular layout, and five closed cavities are constructed through the outer cover 1, the rotating shaft 7 and five sets of rotating plates 6. Driven by the first motor 15, the workpiece is continuously and hidden along a circular trajectory, completing the five major processes of clamping and loading, spraying, impurity removal, air drying and material removal in sequence. This design significantly reduces the risk of operational interference between processes through physical isolation and circular movement line planning. During the air-drying process, the system continuously introduces external gas through the air pipe 13 to ensure the formation of a stable airflow in the air-drying chamber, thereby realizing the air-drying operation. However, the external supplementary gas is likely to contain moisture, which makes the supplementary gas entering the air-drying chamber easily interfere with the air-drying effect. Currently, a desiccant 134 is used to pre-treat the supplementary gas, but the desiccant 134 is very easy to break during use and maintenance, causing debris to enter the air-drying chamber, directly affecting the air-drying quality of the workpiece surface and possibly causing secondary pollution.

[0026] In order to solve the above problems, Figure 9 and Figure 10 As shown, the air pipe 13 located between the two adjacent rotating plates 6 on the right side is connected and arranged on the upper end of the outer cover 1. Air is supplied to the air-drying cavity of the outer cover 1 through the air pipe 13. The mounting pipe 131, which is integrated with the air pipe 13 and arranged obliquely with the left side higher and the right side lower, is connected and installed on the upper end of the air pipe 13. The mounting pipe 131 provides installation space for components such as the fixed filter plate 135. The fixed filter plate 135 is then set in the mounting pipe 131. The fixed filter plate 135 is used to limit the installation between the desiccant 134 and the mounting pipe 131. The desiccant 134 at the right end of the fixed filter plate 135 is filled in the mounting tube 131, and the gas entering the outer cover 1 is dried by the desiccant 134. The movable filter plate 133 at the right end of the desiccant 134 is movably set in the mounting tube 131, and the movable filter plate 133 is used to restrict the installation between the desiccant 134 and the mounting tube 131. The inner wall surface of the mounting tube 131 is recessed outward to form a groove, and the groove provides an installation space for the retaining spring 132. The retaining spring 132 attached to the right end of the movable filter plate 133 is assembled on the groove, and the retaining spring 132 is used to restrict the installation between the movable filter plate 133 and the mounting tube 131.

[0027] During use, the second motor 34, the stirring tank 32 and the stirrer are first used to prepare the water-based high-temperature resistant flexible ceramic coating. After the water-based high-temperature resistant flexible ceramic coating is prepared, a conveyor 21 is first used to convey the workpiece to be sprayed to the feeding position, and five rotating plates 6 located in the outer cover 1 are equidistantly arranged on the outer end of the rotating shaft 7, so that the internal space of the outer cover 1 is divided into five cavities by the five rotating plates 6. The five cavities are respectively a feeding cavity connected to the inlet 11, a spraying cavity, a decontamination cavity, an air-drying cavity and a discharging cavity connected to the outlet 12. Then, the workpiece to be sprayed is placed into the feeding cavity in the outer cover 1 through the inlet 11; The pressure plate 46, the elastic member 44 and the bracket 41 are then used to quickly clamp the workpiece to be sprayed. The first motor 15, the rotating shaft 7, the five rotating plates 6, the five mounting plates 4 and the five brackets 41 are then used to sequentially allow the clamped workpiece to be sprayed to enter the spraying chamber, the impurity removal chamber, the air-drying chamber and the discharge chamber. The pump 31, the first main pipe 181, the multiple first vertical pipes 182 and the multiple atomizing nozzles 183 are first used to spray the clamped workpiece to be sprayed in the spraying chamber. The fan 5, the second cover 53 and the second pipe 54, the conical cylinder 552, the multiple guide cylinders 42 are then used to remove floating impurities in the impurity removal chamber. Then, the fan 5, the first cover 51, multiple suction pipes 192, multiple second vertical pipes 191, the second main pipe 193 and the first pipe 52 are used to extract gas from the air-drying chamber and form an airflow, so as to solidify the ceramic coating sprayed on the surface of the workpiece, and then complete the workpiece spraying operation. Then, the workpiece in the discharge chamber is disassembled and removed, and the removed workpiece is placed on the conveyor 21 on the right, and the conveyor 21 on the right is used to transport the removed workpiece out.

[0028] During the process of extracting gas from the air-drying chamber, the external gas enters the installation tube 131 and passes through the movable filter plate 133, the desiccant 134 and the fixed filter plate 135 in sequence. At this time, the movable filter plate 133 and the fixed filter plate 135 will filter the external gas, and at the same time, the desiccant 134 dries the external gas. Then, the treated external gas enters the air-drying chamber through the air pipe 13, thereby replenishing the gas into the air-drying chamber, thereby ensuring the formation of a continuous airflow in the air-drying chamber, realizing the treatment of the external gas entering the air-drying chamber in the outer cover 1, effectively reducing the probability of interference with the air-drying operation of the workpiece due to factors such as moisture in the external gas, and effectively ensuring the spraying effect and quality.

[0029] Because the mounting tube 131 is in an inclined state with the left side higher and the right side lower, the desiccant 134 inside the mounting tube 131 is in an inclined state with the left side higher and the right side lower as a whole. During maintenance, the retaining spring 132 is first removed to release the restriction on the movable filter plate 133, and then the movable filter plate 133 is taken out from the mounting tube 131. At this time, the desiccant 134 in the mounting tube 131 will automatically slide outward, effectively reducing the probability of debris entering the air drying chamber due to the breakage of the desiccant 134 during use and maintenance, effectively reducing the probability of secondary contamination of the workpiece, and effectively ensuring the spraying effect and quality.

[0030] Although this specification is described according to implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
