Description

Technical Field

[0001] The invention relates to a functional ceramic sheet cleaning device, in particular to a wet cleaning device for functional ceramic sheets. Background Art

[0002] Functional ceramics refer to materials whose applications primarily utilize their non-mechanical properties. These materials typically possess one or more functions, such as electrical, magnetic, optical, thermal, chemical, and biological. Some also have coupled functions, such as piezoelectricity, piezomagnetics, thermoelectricity, electro-optics, acousto-optics, and magneto-optics. With the rapid development of materials science, the various new properties and applications of functional ceramic materials are increasingly being recognized and actively explored.

[0003] With the large-scale development and application of functional ceramics, the market demand is growing. The traditional preparation process and supporting equipment can no longer meet the needs of large-scale processing, and cleaning film is one of the links.

[0004] Usually, ceramic sheets are densified by stacking and firing, and their shapes are as follows: Figure 4 As shown, in order to prevent the adhesion of ceramic sheets caused by high temperature sintering, a layer of isolation powder is usually sprinkled between the ceramic sheets. After the functional ceramic sheets are sintered out of the furnace, a large amount of isolation powder adheres to their surface, which needs to be manually dispersed into Figure 5 After the functional ceramic sheet is cleaned, the isolation powder on the surface is removed, which is commonly known as cleaning sheet. However, due to the brittleness of the functional ceramic sheet itself, some common automated machines for polishing and grinding are not suitable for cleaning functional ceramic sheets, and the ceramic sheet can easily be broken during the process. Therefore, the common method of cleaning sheets at present is for workers to spread the functional ceramic sheet flat on a special cleaning plate, and then manually grind it with sandpaper. After grinding one side, turn it over and grind the other side. Although this method is relatively safe and will not damage the ceramic sheet, its efficiency is very low, the labor input is large, and some of the dust from the grinding will be scattered in the surrounding air, the working environment is poor, and it causes damage to the health of workers. In today's market demand, it cannot meet the needs of large-scale production and processing. Therefore, it is very necessary to design an efficient and safe cleaning device for functional ceramic sheets. Summary of the Invention

[0005] The purpose of the present invention is to provide a functional ceramic sheet wet cleaning device, which has the characteristics of high cleaning efficiency, no damage to the ceramic sheet, low labor input, no dust dispersion, and good working environment.

[0006] The technical solution of the present invention is a wet-type cleaning device for functional ceramic sheets, comprising a bracket, a grinding barrel provided above the bracket, a convex ring provided on the circumference of the grinding barrel, a driving wheel provided on the bracket below the convex ring and cooperating with the convex ring, and the driving wheel being connected to a driving motor via a transmission device;

[0007] The grinding barrel includes a cleaning segment, the two ends of which are respectively connected to a trumpet-shaped discharge segment and a feed segment, wherein the inner walls of the cleaning segment and the discharge segment are provided with a plurality of spirally arranged ribs, and the spacing between adjacent ribs is less than the minimum width of the functional ceramic sheet;

[0008] A spray pipe is suspended above the grinding barrel, a spray head is provided below the spray pipe, and one end of the spray pipe is connected to a water supply device after extending out of the grinding barrel.

[0009] In the aforementioned wet cleaning device for functional ceramic sheets, the transmission device is a transmission rod axially fixedly connected to the driving wheel, and the transmission rod is fixedly connected to the rotating shaft of the driving motor.

[0010] In the wet cleaning device for the functional ceramic sheet mentioned above, the barrel wall of the cleaning segment is provided with drainage holes arranged in a ring shape.

[0011] In the wet cleaning device for the functional ceramic sheet, the central axis of the cleaning segment is horizontal, and the cleaning segment as a whole has a larger diameter at one end close to the feed section and a smaller diameter at the other end close to the feed section. The drainage hole is located at the end of the cleaning segment close to the feed section.

[0012] In the aforementioned wet cleaning device for functional ceramic sheets, the slope of the lower side of the cleaning segment is 1-3°.

[0013] In the aforementioned wet cleaning device for functional ceramic sheets, a water collecting tank is provided below the drainage hole, and a drainage pipe is provided at the bottom of the water collecting tank.

[0014] In the aforementioned wet cleaning device for functional ceramic sheets, a water pump is installed in the middle of the spray pipe.

[0015] In the aforementioned wet cleaning device for functional ceramic sheets, the water supply device is a water storage barrel, and is arranged above the grinding barrel.

[0016] In the aforementioned wet cleaning device for functional ceramic sheets, the thickness of the ribs is 3-5 mm.

[0017] In the aforementioned wet cleaning device for functional ceramic sheets, the side of the rib that contacts the ceramic sheet is in an arc shape.

[0018] Beneficial effects of the present invention

[0019] 1. The present invention drives the grinding barrel by a driving motor to grind the ceramic disc by mechanical processing. Compared with the traditional manual cleaning method, the cleaning efficiency is greatly improved, the labor input is reduced, and it can fully meet the needs of large-scale production.

[0020] 2. The present invention provides spirally distributed ribs in the grinding barrel and controls the spacing between them to be smaller than the minimum width of the ceramic sheet. The ribs have three functions: (1) when the grinding barrel rotates forward and reverse, they can respectively play the role of grinding and discharging; (2) increase the roughness of the barrel wall, increase the friction between the abrasive and the ceramic sheet, make the abrasive and the ceramic sheet turn and rub in the grinding barrel, and increase the grinding frequency; (3) avoid the ceramic sheet from being brought from a low place to a high place, especially when the ceramic sheet is wet, it will stick to the inner wall of the grinding barrel and be brought to the top. When the ceramic sheet falls from a high place or even the top, it is easy to break. Therefore, the narrow rib design can act as a bridge to prevent the ceramic sheet from being closely attached to the inner wall of the grinding barrel. When the ceramic sheet is brought to a certain height (usually not more than half the height of the grinding barrel), it will fall under the action of its own gravity and roll with the abrasive, completing the grinding while avoiding breaking. Therefore, the present invention improves the efficiency of cleaning the sheet through the above design, and at the same time, it has the advantage of not breaking the ceramic sheet and not being damaged. In addition, according to the current actual processing situation, the broken ceramic pieces are caused by micro cracks during the molding and sintering processes. During the wet cleaning process, the expansion of the cracks leads to breakage. From this perspective, compared with the manual cleaning method, the present invention also has the effect of automatically removing defective products.

[0021] 3. By rationally designing the rib thickness, the present invention prevents excessive rib thickness from forming a platform that would otherwise lift the ceramic sheet to a higher position. Furthermore, by designing the ribs in contact with the ceramic sheet in an arc shape, the contact between the ribs and the ceramic sheet is smoother during rotation, preventing damage to the ceramic sheet surface caused by sharp corners. This further improves safety during the cleaning process, prevents breakage of the ceramic sheet, and provides a damage-free experience.

[0022] 4. The present invention is a wet cleaning sheet, that is, by setting a water spray pipe in the grinding barrel, it can prevent the dust in the grinding barrel from spreading everywhere, ensuring a better working environment; at the same time, the spraying water can also thoroughly clean the ceramic sheet, eliminating the subsequent cleaning process and further improving the overall processing efficiency of the ceramic sheet.

[0023] In summary, the present invention has the advantages of high cleaning efficiency, low ceramic plate damage rate, low labor input, less dust dispersion and good working environment. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] The present invention will be further described below with reference to the examples, but they are not intended to limit the present invention.

[0031] Embodiments of the present invention

[0032] A wet cleaning device for functional ceramic sheets, as shown in the attached Figure 1-3 As shown, it includes a bracket 1, a rolling barrel is provided above the bracket 1, a convex ring 2 is provided on the circumference of the rolling barrel, a driving wheel 3 cooperating with the convex ring 2 is provided on the bracket 1 below the convex ring 2, and the driving wheel 3 is connected to the driving motor 5 through a transmission device 4; the rolling barrel includes a cleaning segment 6, and the two ends of the cleaning segment 6 are respectively connected to a trumpet-shaped discharge segment 7 and a feed segment 8, wherein the inner walls of the cleaning segment 6 and the discharge segment 7 are provided with a plurality of spirally arranged ribs 9, and the spacing between adjacent ribs 9 is less than the minimum width of the functional ceramic piece; a spray pipe 11 is suspended above the inside of the rolling barrel, and a spray head 12 is provided below the spray pipe 11, and one end of the spray pipe 11 is connected to a water supply device 14 after extending out of the rolling barrel.

[0033] During operation, the abrasive and the peeled ceramic sheets are first placed into the grinding barrel from the feed port of the feed section 8, and the drive motor 5 is started to rotate the grinding barrel in a direction that prevents the material from being discharged from the discharge section 7. During the rotation, the material inside is lifted toward the rising side by the friction provided by the ribs 9. After reaching a certain height, it falls and continuously tumbles, causing continuous friction between the abrasive and the functional ceramic sheet to complete the grinding of the functional ceramic sheet. During the tumbling process, the water supply device 14 sprays water into the interior through the spray pipe 11 and the spray head 12. The sprayed water can absorb dust in the air. At the same time, the functional ceramic sheet is cleaned during the tumbling process of the material. When the cleaning time is over, the driving motor 5 is reversed, and the abrasive and functional ceramic sheets are moved toward the side of the discharge section 7 under the action of the spiral ribs and discharged from the discharge port of the discharge section 7. The discharged materials are simply screened to separate the functional ceramic sheets and the abrasive, and the abrasive continues to be sent to the rolling mill for cleaning, and the functional ceramic sheets are sent to the next processing step.

[0034] Furthermore, the transmission device 4 is a transmission rod axially fixedly connected to the driving wheel 3, and the transmission rod is fixedly connected to the rotating shaft of the driving motor 5. The transmission is carried out by the transmission rod, and the structure is simpler.

[0035] Furthermore, the barrel wall of the cleaning segment 6 is provided with a ring-shaped arrangement of drainage holes 10, and the water in the cleaning process is discharged from the drainage holes 10, which can discharge dust in time to avoid secondary pollution caused by deposition, and is more convenient for drainage.

[0036] Furthermore, the central axis of the cleaning segment 6 is horizontal, and the cleaning segment 6 as a whole has a large diameter at one end close to the feed segment 8 and a small diameter at the other end close to the feed segment 8. The drainage hole 10 is located at the end of the cleaning segment 6 close to the feed segment 8. During the cleaning process, water will gather at the low point at one end of the feed segment 8 and be discharged from the drainage hole 10 there, so that the sewage is discharged more thoroughly.

[0037] Furthermore, the slope of the lower side of the cleaning segment 6 is 1-3°. When the slope is too small, it is not conducive to the water gathering in the lower part. When the slope is too large, the material will be concentrated in the lower part to form an accumulation, affecting the cleaning effect. Therefore, setting 1-3° is more appropriate.

[0038] Furthermore, a water collecting trough 15 is provided below the drainage hole 10 , and a drainage pipe 16 is provided at the bottom of the water collecting trough 15 . The water discharged from the drainage hole 10 is collected by the water collecting trough 15 and then transferred to the sewage treatment area through the drainage pipe 16 .

[0039] Furthermore, a water pump 13 is installed in the middle of the spray pipe 11. The water pump 13 provides a certain water pressure so that the water sprayed from the spray head 12 has a certain impact force, thereby improving the cleaning effect of the functional ceramic sheet surface.

[0040] Furthermore, the water supply device 14 is a water storage barrel and is arranged above the grinding barrel.

[0041] Furthermore, the thickness of the rib 9 is 3-5 mm.

[0042] Furthermore, the side of the rib 9 that contacts the ceramic sheet is in an arc shape. In the actual manufacturing process, the rib 9 is directly made of steel wire with a diameter of 3-5 mm.

[0043] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, can make equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, which should be covered by the scope of protection of the present invention.
