Description

Technical Field

[0001] This utility model belongs to the field of ceramic ball production technology, and more specifically, relates to a ball polishing and sorting device. Background Technology

[0002] Ceramic balls are a type of high-performance mechanical parts. Compared with metal balls of the same diameter, ceramic balls have many advantages, such as light weight, high rigidity, high hardness, low coefficient of friction, low coefficient of thermal expansion, high temperature resistance, rust resistance, and corrosion resistance. Therefore, they have become core components of high-end bearings, valves, measuring instruments, etc., and are widely used in aerospace, chemical, metallurgical, medical, food, oilfield, precision electronics and many other fields. Due to the special service environment of high-speed bearings, valves and other components, the requirements for the surface quality of ceramic balls are extremely stringent. Cracks and oxide pores on the surface of the ball can have a serious negative impact on its safety and lifespan. Therefore, surface defect detection technology for ceramic balls is one of the key technologies in this industry.

[0003] The powder metallurgy process and the grinding and polishing process of ceramic balls are complex and involve many uncertainties, resulting in a wide variety of defects on the surface of ceramic balls. Furthermore, due to the large volume of ceramic balls used, manufacturers produce a significant number daily. To ensure product output and quality, manual inspection is currently the primary method, which is labor-intensive and inefficient. Moreover, internal defects in ceramic balls are often difficult to detect manually, leading to inconsistent product quality. Additionally, the production process requires polishing and cleaning the rough ceramic balls to obtain the finished products. As the ball bearing material, the smoothness of the outer surface of the ceramic ball is a crucial parameter. Therefore, a device is needed to perform preliminary inspection of the ceramic balls, reducing the workload of workers and ensuring proper polishing of the ceramic ball surface to guarantee good product quality.

[0004] This invention can be used to sort ceramic balls and polish ceramic balls. Utility Model Content

[0015] 1. By setting up a temporary storage bin, the defective ceramic balls can be detected. There is a vertical drop of 2.5-3.5 meters between the forward and reverse conveyor belts and the bottom of the temporary storage bin. The ceramic balls are dropped from a height. During the drop, the gravitational potential energy is converted into kinetic energy. The accumulated kinetic energy will shatter some defective ceramic balls.

[0016] 2. By setting up a vibrating belt screen, the ceramic balls are sorted. Under the vibration of the vibrating motor, qualified products roll down to the next belt under the action of gravity, while unqualified products, after falling from the temporary storage bin, have been broken into irregular products and will be seriously pushed out of the belt in the opposite direction, thus sorting out the good ceramic balls.

[0017] 3. By setting up a polishing machine, the ceramic balls are polished; the first drive motor is started, which drives the polishing cylinder to rotate. The product is rubbed in the polishing machine due to the rotation of the polishing machine and the counter-rotation of the cylinder wall. Under the action of water flow, the purpose of cleaning and polishing is achieved. The wear-resistant damping baffle can effectively enhance the polishing effect.

[0018] 4. The entire device enables ceramic balls to undergo five screening processes. On the unloading platform, workers perform preliminary screening of the products, completing the first screening process for material distribution. Then, the ceramic balls are thrown into a temporary storage bin from the forward and reverse belt conveyors, where workers can further screen the ceramic balls, completing the second high-altitude drop screening process. Next, the ceramic balls enter the first vibrating belt screen, completing the second shaking screening process. They then enter the polishing machine for polishing and washing, and are then screened through the second vibrating belt screen, completing the fourth polishing and washing screening process. Finally, the fifth manual loading and screening process is completed during manual loading in the sorting bin.

[0019] 4. In summary, this ball polishing and sorting device, by being equipped with a temporary storage bin, a vibrating belt screen, and a polishing machine, can separate and polish ceramic balls. Attached Figure Description

The product is then transported to the first vibrating screen 10 for sorting. Finally, the best-quality products are transported to the intermediate transfer conveyor belt 11. The intermediate drop chamber 12 has two main functions: first, to temporarily store ceramic balls; and second, to allow ceramic balls to fall from a height into the intermediate drop chamber 12 for secondary drop testing of defective balls. After falling into the intermediate drop chamber 12, the ceramic balls enter the polishing machine 13 for polishing. The clean water used for polishing is pumped in from the other end by the water pump 1501, and the wastewater is discharged from the ball outlet end to the water tank of the polishing machine 13 for sedimentation. The settled clean water is discharged through the pipe to the main clean water tank 15 for reuse.

The accumulated kinetic energy shatters some defective ceramic balls.

[0039] In this embodiment of the utility model, the temporary storage bin 7 is composed of several compartments of equal size; each compartment of the temporary storage bin 7 has a discharge port 701 at the bottom of its front end, and a solenoid valve switch is arranged on the discharge port 701 to achieve the effect of controlling the discharge. The solenoid valve switch is existing technology, so its structure is not shown in the figure, but that does not mean that it does not exist.

[0040] In this embodiment of the utility model, connecting blocks 801 are connected to both the front and rear ends of the forward and reverse belt conveyor 8. Connecting holes are formed through the left and right surfaces of the connecting blocks 801.

Guide rods 803 are installed on the bottom of the front connecting block 801 and the connecting holes of the rear connecting block 801. Support blocks 806 are installed at both the left and right ends of the threaded rod 804 and the guide rod 803. A support plate 802 is fixedly connected to the support block 806. A positioning plate 802 is fixedly connected to the right end of the threaded rod 804. The displacement motor 805 is fixedly mounted on the support plate 802. It can deliver products into different compartments of the temporary storage chamber 7. In use, the displacement motor 805 drives the threaded rod 804 to rotate, which causes the connecting block 801 to move, thereby enabling the forward and reverse belt conveyor 8 to move left and right. The forward and reverse belt conveyor 8 is an existing device that can realize the forward and reverse rotation of the belt. The forward and reverse belt conveyor 8, which can rotate the belt in both directions and can move the displacement 805 left and right, can deliver products into different compartments of the temporary storage chamber 7.

[0041] In this embodiment of the utility model, the first vibrating belt screen 10 includes: a vibrating belt 1001, a support 1002, a load-bearing spring 1003, a vibrating motor 1004, and a mounting plate 1005. The vibrating belt 1001 is provided at the bottom right end of the discharge belt 9. The mounting plate 1005 is installed on the outside of the vibrating belt 1001. The support 1002 is fixedly connected to the front and rear sides of the center of the mounting plate 1005. The load-bearing spring 1003 is fixedly connected to the bottom end of the support 1002. The vibrating motor 1004 is installed at the center of the bottom end of the mounting plate 1005. The first vibrating belt screen 10 has the same structure as the second vibrating belt screen 17. It achieves the effect of sorting ceramic balls. During operation, under the vibration of the vibrating motor 1004, qualified products roll downwards onto the transfer rising belt 11 under the action of gravity. Unqualified products, after falling from the temporary storage bin 7, have been broken into irregular products and will be discharged from the belt in the opposite direction, thereby sorting out good ceramic balls.

[0042] In this embodiment of the utility model, the polishing machine 13 includes: a first rear cover 1301, a first drive motor 1302, a polishing cylinder 1303, a support frame 1304, and a wear-resistant damping baffle 1305. The first rear cover 1301 is fixedly installed at the front end of the transfer drop chamber 12. The polishing cylinder 1303 is movably connected to the front end of the first rear cover 1301. The wear-resistant damping baffle 1305 is provided on the inner surface of the polishing cylinder 1303, and the entire inner surface is lined with a 30mm nylon wear-resistant liner. The support frame 1304 is movably connected to the outer sides of the front and rear ends of the polishing cylinder 1303. The first drive motor 1302 is installed at the right end of the polishing cylinder 1303 to polish ceramic balls. The polishing cylinder 1303 has a high front end and a low rear end, with a 1.2-degree inclination. This achieves the effect of polishing ceramic balls. During use, the first drive motor 1302 is started, driving the polishing cylinder 1303 to rotate. The product inside the polishing machine 13 rubs against the cylinder wall due to the rotation of the polishing machine 13, and under the action of water flow, it achieves the purpose of cleaning and polishing. The wear-resistant damping baffle 1305 can effectively enhance the polishing effect. Finally, the ceramic balls polished for a period of time are discharged from the end of the polishing machine 13. The 1.2-degree inclination of the polishing cylinder 1303 allows the ceramic balls to slowly move towards the rear outlet of the polishing cylinder 1303.

[0043] In this embodiment of the utility model, the drying drum 19 includes: a drying cylinder 1901, a second rear cover 1902, a hot air pipe 1903, a second drive motor 1904, and a guide trough 1905.

The drying cylinder 1901 is movably installed at the front end of the second rear cover 1902. The second drive motor 1904 is installed on the right side of the drying cylinder 1901. The guide trough 1905 is provided inside the drying cylinder 1901. The front end of the drying drum 19 is higher than the rear end. The drying tube is inclined at one degree to achieve the effect of drying ceramic balls. During use, the hot air pipe 1903 is connected to waste heat air from the kiln 1 at an 80-120 degree angle. Then, the second drive motor 1904 is started, driving the ceramic balls to move slowly along the guide chute 1905 out of the drying drum 19. Furthermore, the drying drum 19 should be equipped with a support device to support the drying drum 1901 and the second drive motor 1904, depending on the site conditions. The drying tube is inclined at one degree, allowing the ceramic balls to slowly move towards the rear outlet of the drying drum 19. Additionally, the drying drum 19 should be equipped with a support device to support the drying drum 1901 and the second drive motor 1904, depending on the site conditions.

[0044] Working principle: During operation, the product is automatically transported to the return line 3 via the shuttle car 2 at the end of the kiln 1. Then, it automatically shifts 805 to the unloading platform 4 at the end of the return line 3. The operator then controls the machine to unload the product into the unloading platform 4. The product is then transported to the bridge belt 6 via the unloading inclined belt 5 at the bottom of the unloading platform 4. The bridge belt 6 then transports the product to the forward and reverse belt conveyor. The forward and reverse belt conveyor stores the product in the temporary storage bin 7. The displacement 805 motor drives the threaded rod 804 to rotate, which allows the connecting block 801 to move, thus enabling the forward and reverse belt conveyor 8 to move left and right. The forward and reverse belt conveyor 8 is an existing device that can realize the forward and reverse rotation of the belt. The forward and reverse belt conveyor 8, which can rotate the belt in both directions and shift left and right 805, allows the forward and reverse belt conveyor 8 to send the product into different bins of the temporary storage bin 7. The forward and reverse belt conveyor 8 is 2.5-3 meters away from the bottom of the temporary storage bin 7.With a vertical drop of 5 meters, ceramic balls are dropped from a height. During the fall, gravitational potential energy is converted into kinetic energy, and the accumulated kinetic energy shatters some defective balls. The bottom of the temporary storage bin 7 has a discharge port 701. The solenoid valve can be controlled to allow products to fall from the temporary storage bin 7 onto the discharge belt 9, which then transports them to the first vibrating screen 10. Under the vibration of the vibrating motor 1004, qualified products roll downwards under gravity onto the intermediate rising belt 11, while unqualified products, having already fallen from the temporary storage bin 7, are shattered into irregular shapes, which will severely impact the product quality. The heavy conveyor belt exits in the opposite direction, thus separating the good ceramic balls and completing the product sorting. Finally, the good products are transported to the transfer drop chamber 12 via the transfer rising conveyor belt 11. The ceramic balls fall from a higher position into the transfer drop chamber 12, where problematic balls undergo a second drop test. They then enter the polishing machine 13 for polishing. The first drive motor 1302 is started, driving the polishing cylinder 1303 to rotate. Inside the polishing machine 13, the products rub against the counter-rotating cylinder wall due to the rotation of the polishing machine 13, achieving cleaning and polishing under the action of water flow. This process enhances wear resistance. The baffle 1305 effectively enhances the polishing effect. Finally, the ceramic balls, polished for one period, are discharged from the end of the polishing machine 13. The polishing water is pumped in from the other end by the water pump 1501. Wastewater is discharged from the ball outlet to the lower water tank of the polishing machine 13 for sedimentation. The settled water is discharged through a pipe to the main clear water tank 15 for reuse. Next, the ceramic balls enter the second vibrating belt screen 17. Under the vibration of the vibrating motor 1004, qualified products roll downwards onto the first lifting belt 18 under gravity, while unqualified products pass through the screen. The ceramic balls, already broken into irregular shapes, fall from the drop chamber 12 and are conveyed out in the opposite direction by a conveyor belt. This separates the good ceramic balls, which then enter the drying drum 19. The hot air pipe 1903 is connected to waste heat air from the kiln 1 at 80-120 degrees Celsius. The second drive motor 1904 is then activated, moving the ceramic balls and allowing them to slowly move out of the drying drum 19 along the guide chute 1905. After drying, the ceramic balls exit the drying drum 19 and are finally conveyed to the sorting chamber 21 via the second lifting conveyor belt 20.

[0045] The entire device enables ceramic balls to undergo five screening processes. On the unloading platform 4, workers perform preliminary screening of the products, completing the first screening process for material distribution. Then, the ceramic balls are thrown into the temporary storage bin 7 from the forward and reverse belt conveyors 8, where workers can further screen the ceramic balls, completing the second high-altitude drop screening process. Next, the ceramic balls enter the first vibrating belt screen 10, completing the second shaking screening process. They then enter the polishing machine 13 for polishing and washing, and are then screened through the second vibrating belt screen 17, completing the fourth polishing and washing screening process. Finally, during manual loading in the sorting bin 21, the fifth manual loading and screening process is completed.

[0046] In addition, various belts in this device are equipped with power output devices to drive the belts to rotate. Each rising belt is equipped with a baffle to enable it to lift the ceramic balls. Appropriate support devices should also be provided according to the terrain to fix the position of the components of this device. It also includes devices such as tension pulleys to ensure the stable operation of the belts. Since the installation and use of belts is already very widespread, the methods of installing belts, driving belts, and ensuring the stable operation of belts have long been common knowledge. Although the belt drive devices and support devices are not shown in the attached drawings, it does not mean that they do not exist. They are simply not shown because they can be set according to different terrains and the setting method is common knowledge and not the inventive point of this patent.
