[0002] Specialty ceramics refer to high-performance ceramic materials with special physical, chemical, or mechanical properties. They are mainly used in functional or structural applications requiring high strength, high temperature resistance, wear resistance, corrosion resistance, electrical insulation, and thermal conductivity. Examples include machining tools, brake discs, and bearings. For bearings, the primary coating area is the raceway. The production process of specialty ceramics requires the use of powder coating equipment to apply powder to the ceramic surface.

[0003] The main components of powder coating equipment include: a feeding system consisting of a storage hopper, conveying pipes, and a vibrating screen (for filtering powder impurities); a spraying mechanism consisting of an adjustable powder spray head / ring nozzle, which is precisely positioned via a telescopic rod or multi-directional slide rail; a drive control system consisting of a motor, gear set, and CNC system to adjust the speed and spraying trajectory; and some equipment also includes a recycling device: a dust collection hood, filter element, or powder scraper to reduce waste and maintain environmental cleanliness.

[0004] When powder coating the raceway on the outer wall of the bearing inner ring, traditional powder coating operations mostly involve spraying powder directly from the nozzle. In this case, the bearing inner ring moves to the nozzle position under the movement of the conveyor belt, resulting in a higher powder density on the front side of the bearing surface and a lower powder density on the back side. Therefore, the powder adhering to the bearing raceway surface is prone to unevenness, which affects product quality. Utility Model Content

[0028] Example:

[0029] Reference Figures 1-4 A special ceramics production powder spraying equipment includes a powder spraying box 1 and a conveyor belt 2. The conveyor belt 2 passes through the powder spraying box 1, carrying the inner ring of the bearing through the powder spraying box 1 for powder spraying. It also includes multiple sets of rotating seats 201 for fixing the bearings, and multiple sets of fixed seats 202 fixedly connected to the conveyor belt 2. The multiple sets of fixed seats 202 are equidistantly distributed along the contour of the conveyor belt 2. There are two to thirty sets of fixed seats 202; preferably, there are twenty-four sets. Twenty-four sets of rotating seats 201 are correspondingly provided, rotatably connecting the rotating seats 201 to the fixed seats 202. The powder spraying box 1 is equipped with a drive unit for driving the rotating seats 201 to rotate. In use, the rotation is driven by the drive unit. The rotating base 201 allows the inner ring of the bearing to rotate, facilitating powder spraying and reducing uneven powder spraying in a single application, thus improving powder spraying quality. A powder spraying plate 3 is movably installed inside the powder spraying box 1, with at least one nozzle 301 fixedly connected to it for spraying powder onto the inner ring raceway. Here, three nozzles 301 are equidistantly arranged along the bearing's direction of movement, allowing for powder spraying into the raceway during bearing rotation, reducing uneven spraying and improving performance. A feeding system is fixedly connected to the outer wall of one side of the powder spraying box 1, and the powder spraying plate 3 is connected to the output end of the feeding system via a flexible hose for feeding the nozzles 301.

[0030] During use, continuous powder spraying can be achieved by using a conveyor belt to transport the two bearings. Moreover, the bearings can rotate during the movement, which can reduce the phenomenon of uneven powder spraying and improve product quality.

[0031] Reference Figure 3 A plug-in post 203 is fixedly connected to the top of the rotating base 201. The plug-in post 203 extends into the center hole of the inner ring, and the outer wall of the plug-in post 203 is interference-fitted with the center hole of the inner ring to fix the inner ring and facilitate rotation of the inner ring. Moreover, the plug-in post 203 is preferably made of rubber. On the one hand, it is convenient to fix the inner ring, and the rotating base 201 can rotate with the inner ring during rotation. On the other hand, it is easy to install and disassemble, which can avoid damage to the inner ring and affect product quality.

[0032] Reference Figure 3 A rotating cavity is provided inside the rotating seat 201, and a rotating plate 204 is rotatably connected inside the rotating cavity. One end of the fixed seat 202 extending into the rotating cavity is fixedly connected to the rotating plate 204. In use, by rotatably connecting the rotating plate 204 to the rotating seat 201, the fixed seat 202 and the rotating plate 204 are fixedly connected, which can ensure that the rotating seat 201 rotates reliably and improve the use effect.

[0033] Reference Figure 3 The drive unit can be driven by a motor to rotate the rotating seat 201. Here, we design the drive unit to have a rack 701 fixedly connected to the inner wall of the powder spraying box 1, so that the side wall of the rotating seat 201 meshes with the rack 701. When the rotating seat 201 rolls along the rack 701, it rotates at least two revolutions, preferably three revolutions, from the start of engagement to disengagement. In use, by fixing the rack 701 to the inner wall of the powder spraying box 1, when the conveyor belt 2 moves the rotating seat 201 to the position of the rack 701, the rotating seat 201 meshes with the rack 701. As the conveyor belt 2 continues to move forward, the rotating seat 201 rolls over the rack 701, rotating the inner ring of the bearing, and spraying powder during rotation, thus improving the performance.

[0034] Reference Figure 3 A fixing bracket 7 is fixedly connected to the inner wall of the powder spraying box 1 by a first screw. The rack 701 is fixedly connected to the end of the fixing bracket 7 away from the powder spraying box 1 by a second screw, which facilitates the fixing of the rack 701 and improves the performance.

[0035] Reference Figure 3 An electric slide table 5 is fixedly installed at the top inside the powder spraying box 1. A base 501 is fixedly connected to the sliding seat of the electric slide table 5. The sliding direction of the sliding seat is perpendicular to the material conveying direction of the conveyor belt 2. The base 501 is preferably fixed to the sliding seat with a third screw. An mounting plate 502 is fixedly connected to the bottom of the base 501. The powder spraying plate 3 is lifted and connected to the mounting plate 502. In use, by starting the electric slide table 5, the distance between the nozzle 301 and the workpiece can be adjusted. Then, the powder spraying plate 3 is lifted and connected to the mounting plate 502. This is suitable for spraying powder at different height positions of the workpiece, thus improving the application range.

[0036] Reference Figure 3 and Figure 4The powder spraying plate 3 can be raised and lowered using a pneumatic cylinder, hydraulic cylinder, or electric telescopic cylinder. Here, a connecting rod 4 is fixedly connected to the powder spraying plate 3. The connecting rod 4 has a Z-shaped structure. A limit block 401 is fixedly connected to the end of the connecting rod 4 away from the powder spraying plate 3. The limit block 401 is slidably connected to the mounting plate 502. A limiting element is provided in the mounting plate 502 to limit the sliding of the limit block 401. In use, by driving the limit block 401 to slide in the mounting plate 502, the powder spraying height of the nozzle 301 can be adjusted to improve the usage effect.

[0037] Reference Figure 3 and Figure 4 The limiting component can have equidistantly distributed through holes on the mounting plate 502, and then the limiting block 401 can be fixed in a suitable position using bolts or pins. Here, the limiting component is designed with a screw 6 threadedly connected to the limiting block 401, and a guide groove 503 is provided on the mounting plate 502. The limiting block 401 is slidably connected in the guide groove 503. A pad 601 is fixedly provided at the end of the screw 6 extending out of the guide groove 503, and a knob 602 is fixedly connected at the end of the pad 601 away from the screw 6. Furthermore, the inner wall of the pad 601 abuts against the outer wall of the mounting plate 502. During use, by loosening the knob 602, the limiting block 401 can be driven to slide up and down along the guide groove 503 to adjust the powder spraying height of the nozzle 301. After adjustment, tightening the knob 602 will cause the inner wall of the pad 601 to abut against the outer wall of the mounting plate 502, thus fixing the limiting block 401 in the current position. In addition, anti-slip textures are fixedly connected to both the inner wall of the pad 601 and the outer wall of the mounting plate 502 to reduce slippage and improve the fixing effect.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
