Description

Technical Field

[0001] The invention relates to a functional ceramic sheet cleaning device, in particular to a dry type functional ceramic sheet cleaning device. Background Art

[0002] Functional ceramics refer to materials that are mainly used for their non-mechanical properties during application. Such materials usually have one or more functions, such as electricity, magnetism, light, heat, chemistry, biology, etc. Some also have coupling functions, such as piezoelectricity, piezomagnetics, thermoelectricity, electro-optics, acousto-optics, magneto-optics, etc. With the rapid development of materials science, various new properties and new applications of functional ceramic materials are constantly being recognized and actively developed.

[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. Figure 4 As shown, in order to prevent the ceramic sheets from sticking together due to high temperature sintering, a layer of isolating powder is usually sprinkled between the ceramic sheets. A large amount of isolating powder is deposited on the surface of the ceramic sheets, and it needs to be manually dispersed into Figure 5 After the sheet-shaped functional ceramic sheet shown in the figure is cleaned, the isolation powder on the surface is removed, which is also called a cleaning sheet. However, due to the high 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 sheets can be easily broken during the process. Therefore, the common method of cleaning sheets at present is that workers lay the functional ceramic sheets flat on a special cleaning sheet tray, and then manually grind them with sandpaper. After grinding one side, they turn 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 the 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 dry cleaning device for functional ceramic sheets, which has the characteristics of high cleaning efficiency, low ceramic sheet damage rate, low labor input, less dust dispersion and good working environment.

[0006] The technical solution of the present invention is: a dry cleaning device for functional ceramic sheets, comprising a bracket, a grinding barrel is arranged above the bracket, a convex ring is arranged on the circumference of the grinding barrel, a driving wheel matched with the convex ring is arranged on the bracket below the convex ring, and the driving wheel is connected to a driving motor via a transmission device;

[0007] The grinding barrel includes a cleaning segment, and the two ends of the cleaning segment 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] The dry cleaning device for functional ceramic sheets mentioned above has an exhaust pipe suspended above the grinding barrel, a dust collecting hood is provided below the exhaust pipe, and one end of the exhaust pipe extends out of the grinding barrel and is connected to an exhaust fan and a dust collector in sequence.

[0009] In the dry cleaning device for the functional ceramic discs, 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] The dry cleaning device for the functional ceramic sheet mentioned above, wherein the dust collector is a bag dust collector.

[0011] In the dry cleaning device for the functional ceramic sheet mentioned above, the thickness of the ribs is 3-5 mm.

[0012] In the dry cleaning device for the functional ceramic sheet, the side of the rib in contact with the ceramic sheet is in an arc shape.

[0013] Beneficial Effects of the Invention

[0014] 1. The present invention drives the grinding barrel by driving the motor to grind the ceramic sheet 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.

[0015] 2. The present invention provides spirally distributed ribs in the grinding barrel and controls the spacing between the ribs 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, it can play the role of grinding and discharging respectively; (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 bringing the ceramic sheet from a low place to a high place. When the ceramic sheet falls from a very high place, it is easy to break. Therefore, the narrower rib design can play the role of 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 not only improves the efficiency of cleaning the sheet through the above design, but also has the advantages that the ceramic sheet will not break and the damage rate is extremely low. In addition, according to the current actual processing situation, there is almost no ceramic chip breakage. Even if there is a very small amount of breakage, it is because cracks appear in the ceramic chip itself during the sintering or peeling process. From this perspective, compared with the manual chip cleaning method, the present invention also has the effect of automatically removing defective products.

[0016] 3. The present invention reasonably sets the thickness of the ribs to avoid the ribs being too thick to form a platform and bring the ceramic sheet to a higher place; in addition, by setting the contact side of the ribs with the ceramic sheet to be arc-shaped, the contact between the ribs and the ceramic sheet during rotation is smoother, avoiding damage to the surface of the ceramic sheet caused by sharp corners. Therefore, the safety of the cleaning process is further improved, the ceramic sheet is avoided from being broken, and it has the advantage of no damage.

[0017] 4. Although the present invention is a dry cleaning sheet, by arranging an exhaust pipe and a dust collecting hood in the grinding barrel, the air containing a large amount of dust can be promptly extracted from the grinding barrel and uniformly collected and processed, which can prevent the dust in the grinding barrel from spreading everywhere and ensure a better working environment.

[0018] 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

[0028] During operation, the abrasive and the peeled ceramic sheet are first placed into the grinding barrel from the feed port of the feed section 8, and the drive motor 5 is started to drive the grinding barrel to rotate in the direction in which the material will not be discharged from the discharge section 7. During the rotation process, the internal material is lifted toward the rising side under the action of the friction provided by the ribs 9, and falls down after reaching a certain height, thereby continuously tumbling, so that the abrasive and the functional ceramic sheet are continuously rubbed against each other, completing the grinding of the functional ceramic sheet. When the cleaning time is over, the drive motor 5 is reversed, and the abrasive and the functional ceramic sheet move toward the side of the discharge section 7 under the action of the spiral ribs and are discharged from the discharge port of the discharge section 7. After the discharged material is simply screened, the functional ceramic sheet and the abrasive can be separated, and the abrasive continues to be sent to the grinding barrel for cleaning, and the functional ceramic sheet is sent to the next processing step.
