Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of grinding machine, concretely relates to a glass ceramic double-sided grinding machine. BACKGROUND

[0002] In the current thriving modern manufacturing industry, glass and ceramic materials are widely used in many fields due to their excellent properties, such as high light transmittance and chemical stability of glass, high hardness and wear resistance of ceramic, etc. From the mobile phone cover glass and smart watch dial in the consumer electronics field to the high-temperature resistant ceramic parts in the aerospace field, from the precision glass lenses of optical instruments to the ceramic substrates in electronic circuits, the demand for these glass and ceramic products is increasing day by day, and the requirement for their processing precision is becoming increasingly stringent. In the production of glass and ceramic, a grinding machine is usually used. However, the existing grinding machine can only grind and polish one side of the workpiece. If both sides of the workpiece need to be ground, the grinding machine needs to be stopped and the workpiece needs to be turned over for re-grinding, which takes a long time and reduces the processing efficiency of the grinding machine.

[0003] A double-sided grinding machine is disclosed in Chinese Patent No. CN 212859037U. The device controls the sun gear to rotate circumferentially through the bottom drive mechanism. The sun gear drives the planetary gear to rotate around it during rotation. The planetary gear revolves around the sun gear through the inner ring gear during rotation. The workpiece inside the placement hole rotates relative to the lower grinding disc and the upper grinding disc during rotation of the planetary gear, so that the upper surface and the lower surface of the workpiece can be ground and polished, greatly improving the processing efficiency of the double-sided grinding machine. However, the device usually uses grinding fluid during processing. When processing glass and ceramic, waste materials will be discharged through the gap between the upper grinding disc and the lower grinding disc. Since no collection mechanism is provided, the waste materials will be thrown on the rack or even the operator, which is inconvenient to collect and affects the appearance.

[0004] Therefore, the utility model is proposed. UTILITY MODEL CONTENTS

Detailed Implementation

[0039] The present invention will now be described in further detail with reference to the accompanying drawings.

[0040] Please see Figures 1-9 As shown, this embodiment provides a glass-ceramic double-sided grinding machine, including a device body 1, a lower grinding disc 2 and an upper grinding disc 3, an annular baffle 4, which is fixedly installed around the lower grinding disc 2 on the device body 1, and a collection groove 25 is defined between the annular baffle 4 and the lower grinding disc 2. A collection hole 16 communicating with the collection groove 25 is provided through the device body 1, and a collection box 11 is fixedly installed inside the device body 1. A filter cylinder 10 is connected to the collection box 11 at the other end and communicates with the collection hole 16. A filter screen 21, a filter bag 9 and an activated carbon adsorption plate 8 are arranged sequentially from top to bottom inside the filter cylinder 10. An inclined guide plate 20 is fixedly installed in the collection box 11 relative to the filter cylinder 10, and an electromagnet 19 is fixedly installed in the collection box 11 relative to the guide plate 20.

[0041] Specifically, during the operation of the glass-ceramic double-sided grinding machine, the mixture of waste material and grinding fluid generated during grinding is thrown to the edge of the lower grinding disc 2 and enters the collection tank 25 defined between the annular baffle 4 and the lower grinding disc 2. The waste material and grinding fluid enter the filter cylinder 10 through the collection hole 16. Inside the filter cylinder 10, the material is filtered and purified sequentially through the filter screen 21, the filter bag 9, and the activated carbon adsorption plate 8. The pre-treated liquid and remaining impurities enter the collection box 11 and flow under the guidance of the guide plate 20. The electromagnet 19 adsorbs the ferromagnetic impurities. The overall structure is simple to operate and can effectively collect and treat the waste material and grinding fluid generated during the grinding process, achieving preliminary filtration and purification of the waste material, reducing environmental pollution, and facilitating the recycling of the grinding fluid.

[0042] It should be noted that in this embodiment, the height of the annular baffle 4 is higher than the height of the connection between the upper grinding disc 3 and the lower grinding disc 2. Secondly, the structure and working principle of the device body 1, the upper grinding disc 3 and the lower grinding disc 2 can be referred to the publication document with patent announcement number CN 212859037U, which is prior art and will not be described here. At the same time, in this embodiment, the electromagnet 19 is controlled by the control device on the device body 1, and the installation and working principle of the electromagnet 19 are also prior art.

[0043] In this embodiment, as Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 7As shown, a ring-shaped guide plate component 7 is fixedly installed on the device body 1 between the lower grinding disc 2 and the annular baffle 4. The collection tank 25 is located between the guide plate component 7 and the annular baffle 4. The guide plate component 7 includes a fixing ring 72 sleeved on the outer wall of the lower grinding disc 2 and an inclined plate 71 fixedly installed on the top of the fixing ring 72. The inclined plate 71 has an inclined end face that is inclined towards the collection tank 25. There is a gap between the fixing ring 72 and the lower grinding disc 2. Specifically, after the mixture of waste material and grinding fluid generated during grinding is thrown to the edge of the lower grinding disc 2, The waste and grinding fluid will fall onto the inclined plate 71 of the guide plate component 7. Since the inclined plate 71 has an inclined end face that is inclined towards the collection tank 25, the waste and grinding fluid will flow into the collection tank 25 along the inclined plate 71. The setting of the guide plate component 7 can more effectively guide the waste and grinding fluid to the collection tank 25, avoid the waste from being scattered randomly on the grinding machine body 1, and improve the efficiency and reliability of waste collection. At the same time, the gap between the fixing ring 72 and the lower grinding disc 2 can prevent the lower grinding disc 2 from rubbing and colliding with the guide plate component 7 during rotation.

[0044] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 7As shown, a guide assembly 17 is movably installed inside the collection tank 25. A drive assembly 5 is provided on the device body 1 to drive the guide assembly 17 to move along the collection tank 25. The drive assembly 5 drives the guide assembly 17 to rotate around the guide plate component 7, thereby guiding the waste in the collection tank 25 to the collection hole 16. The drive assembly 5 includes an external gear 53, which is sleeved and rotatably mounted on the annular baffle 4. The guide assembly 17 is fixedly connected to the external gear 53. A first motor 51 is fixedly installed on the device body 1. A drive gear 52 that meshes with the external gear 53 is fixedly installed on the first motor 51. Specifically, by starting the first motor 51, the drive gear 52 is driven to rotate. Since the drive gear 52 meshes with the external gear 53, the external gear 53 rotates accordingly. The guide assembly 17 is fixedly connected to the external gear 53, thereby realizing the circular motion of the guide assembly 17. During the process, the waste in the collection tank 25 is gradually guided to the collection hole 16. The arrangement of the guiding component 17 and the driving component 5 ensures that the waste in the collection tank 25 can smoothly enter the collection hole 16, avoiding the accumulation of waste in the collection tank 25, ensuring the continuity and stability of waste collection, and improving the efficiency of waste treatment. Furthermore, the guiding component 17 includes a connecting rod 172 and a scraper 171. The connecting rod 172 is fixedly connected to the external gear 53, and the scraper 171 is fixedly installed at the bottom of the connecting rod 172. The scraper 171 is in contact with the bottom wall of the collection tank 25. The scraper 171 can directly contact the bottom wall of the collection tank 25, effectively scraping and guiding the waste to the collection hole 16, improving the waste collection effect and avoiding waste residue on the bottom wall of the collection tank 25. It should be noted that the material of the scraper 171 can be rubber, silicone, etc.

[0045] In this embodiment, as Figure 5 , Figure 6 and Figure 8As shown, the filter screen 21 is slidably disposed inside the filter cylinder 10. The filter cylinder 10 is provided with a vibration assembly 6 for driving the filter screen 21 to vibrate. The vibration assembly 6 includes two drive rods 65, which pass through each other and are movably disposed on the filter cylinder 10. Both drive rods 65 are L-shaped structures. The first end of the two drive rods 65 is fixedly connected to the filter screen 21, and the second end of the two drive rods 65 is fixedly connected to a drive plate 62. A second motor 61 is fixedly installed inside the device body 1. A Z-shaped rod 64 is fixedly installed on the drive shaft of the second motor 61. The end of the Z-shaped rod 64 facing away from the second motor 61 passes through and is movably disposed. The drive plate 62 has a drive groove 63 through which the Z-shaped rod 64 can move. Specifically, by starting the second motor 61, the Z-shaped rod 64 is driven to rotate. The Z-shaped rod 64 moves in the drive groove 63 of the drive plate 62, thereby causing the drive plate 62 to move up and down. The drive plate 62 drives the filter screen 21 to vibrate in the filter cylinder 10 through the drive rod 65. The vibration of the filter screen 21 can prevent waste from clogging the filter screen 21, maintain the filtration efficiency of the filter screen 21, and ensure that waste and grinding liquid can pass smoothly through the filter screen 21 for preliminary filtration, thereby improving the stability and reliability of the entire filtration system.

[0046] In this embodiment, as Figure 8 and Figure 9 As shown, a slider 22 is fixedly mounted on the filter screen 21, and a groove 23 is provided on the filter cylinder 10 for the slider 22 to slide. A corrugated sleeve 24 is movably mounted in the groove 23. The two ends of the corrugated sleeve 24 are fixedly connected to the slider 22 and the inner wall of the groove 23, respectively. Specifically, the cooperation between the slider 22 and the groove 23 ensures the stability and accuracy of the vibration of the filter screen 21. The corrugated sleeve 24 can prevent impurities from entering the groove 23, avoid the slider 22 from being obstructed in the groove 23, and also reduce the wear between the slider 22 and the groove 23, thus extending the service life of the equipment. It should be noted that the installation method between the corrugated sleeve 24 and the slider 22 and the groove 23 is existing technology and will not be described here.

[0047] In this embodiment, as Figure 3 , Figure 5 , Figure 6 and Figure 8 As shown, the top and bottom of the filter cylinder 10 are respectively provided with a feed hopper 12 and a discharge hopper 18 that communicate with the collection hole 16 and the collection box 11. Specifically, the feed hopper 12 and the discharge hopper 18 facilitate the flow of waste and grinding fluid between the filter cylinder 10 and the collection box 11, ensuring the smooth progress of the entire waste treatment process, and also facilitating the cleaning and maintenance of the filter cylinder 10 and the collection box 11.

[0048] In this embodiment, as Figure 3 , Figure 5 and Figure 8As shown, a feed pipe 15 is fixedly installed through the top of the collection tank 11 and communicates with its interior. A drain pipe 13 is connected to the collection tank 11, and an electric valve 14 is fixedly installed on the drain pipe 13 to control its opening and closing. Specifically, the feed pipe 15 facilitates the adjustment and replenishment of the liquid composition in the collection tank 11, and the drain pipe 13 and electric valve 14 facilitate the discharge and control of the treated liquid, thereby improving the flexibility and practicality of the equipment.

[0049] Working principle:

[0050] When the main body 1 is working, the upper grinding disc 3 and the lower grinding disc 2 grind the glass ceramic. The resulting waste and grinding fluid mixture is thrown to the edge of the lower grinding disc 2. The mixture first falls onto the inclined plate 71 of the guide plate component 7. Since the inclined plate 71 has an inclined end face that is inclined towards the collection tank 25, the waste and grinding fluid flow along the inclined plate 71 into the collection tank 25 between the annular baffle 4 and the lower grinding disc 2. The first motor 51 is started by the external control device. The first motor 51 drives the drive gear 52 to rotate. The drive gear 52 interacts with the gear sleeved on the annular baffle 4. The external gear 53 meshes with the upper gear, causing it to rotate. The guide assembly 17 (including the connecting rod 172 and the scraper 171) fixedly connected to the external gear 53 then rotates around the guide plate component 7. The scraper 171 is in contact with the bottom wall of the collection tank 25. During the movement, the waste in the collection tank 25 is gradually guided to the collection hole 16. The waste and grinding liquid enter the feed hopper 12 at the top of the filter cylinder 10 through the collection hole 16, and then enter the filter cylinder 10. Then the second motor 61 is started, and its drive shaft drives the Z-shaped rod 64 to rotate. The drive plate 62 moves within the drive groove 63, causing the drive plate 62 to move up and down, and the drive rod 65 to vibrate the filter screen 21 within the filter cylinder 10. The mixture, after initial filtration by the filter screen 21, continues to flow downwards and is further filtered by the filter bag 9. The filter bag 9 can intercept smaller particulate impurities. Next, the mixture passes through the activated carbon adsorption plate 8, which adsorbs organic matter, odors, etc., achieving further purification. Afterwards, the remaining impurities enter the collection box 11 through the discharge hopper 18. The mixture entering the collection box 11 flows under the guidance of the inclined guide plate 20. The electromagnet 19 is activated by the control device, causing the electromagnet 19 to adsorb ferromagnetic impurities, achieving separation of ferromagnetic substances from the liquid. When it is necessary to discharge the treated liquid, the electric valve 14 on the drain pipe 13 is opened, and the liquid can be discharged from the drain pipe 13. The overall structure is simple to operate and can effectively collect and treat the waste and grinding liquid generated during the grinding process, achieving initial filtration and purification of waste, reducing environmental pollution, and facilitating the recycling of grinding liquid.
