It also includes a blank cutting tool disc (4), a numerical control module (5), and tools (6) with different cutting structures mounted on the tool disc (4). A monitoring device (7) is placed next to the cutting tool disc (4) to input cutting data into the numerical control module (5). The ceramic blank (8) is placed on the ceramic placement platform (3), and the tools (6) cut the ceramic blank according to a set program. The cutting process is monitored by the monitoring device (7). A transparent isolation plate (9) is placed in front of the monitoring device (7), and a prompting device (10) is installed to indicate the progress of the cutting process. The cutting device in the aforementioned patent has the following shortcomings: during the cutting process, deviations are prone to occur, damaging the shape of the blank and resulting in varying degrees of loss.

[0018] A molding process for a fire evacuation ceramic lamp includes the following steps:

[0019] S1: The raw materials for the blank are divided by weight, and after being slurried, they are prepared into clay strips;

[0020] S2: Vacuum refining of the prepared material;

[0021] S3: The clay strips after vacuum roughing are extruded and refined a second time using a vacuum pug mill;

[0022] S4: Cut the obtained clay into a stainless steel mold as needed;

[0023] S5: The steel mold containing the mud is conveyed to the roller pressing equipment for pressing;

[0024] S6: After pressing, the steel mold is placed in the baking room to bake the blank, and then it is demolded to obtain the lamp blank;

[0025] S7: The lamp blank is processed through the above-mentioned fire evacuation ceramic lamp forming equipment;

[0026] S8: The processed lamp blanks are sequentially subjected to glazing, printing, and glazing firing to obtain ceramic lamp products;

[0027] S9: Ceramic lamp products are packaged in different grades.

[0028] Preferably, in step S1, the raw materials for the green body, by weight, include 30-35 parts of premium kaolin, 50-55 parts of potassium feldspar, 10-15 parts of ultrafine quartz, 5-7.5 parts of alumina powder, 2-3 parts of whitening agent, and 3-5 parts of plasticizer.

[0029] Furthermore, in step S1, the composition of the raw material for the billet is controlled as follows: SiO2 64.30%, Al2O3 17-20%, Fe2O3 <0.1%, CaO 0.45-0.75%, MgO 0.25-0.4%, TiO2 <0.05%, K2O 6-7%, Na2O 1-1.5%, and other 2-3%, with the loss on ignition controlled at 5-6%.

[0030] A further preferred embodiment: the amount of alumina powder added accounts for 4.5% to 7% of the total mass of the raw material.

[0031] As a preferred embodiment of the present invention: in step S3, the rotational speed of the extrusion shaft of the vacuum pumice machine is controlled at 20-25 r / min, and the vacuum degree is controlled at 98% or higher.

[0034] Based on the aforementioned scheme: In step S8, the temperature of the second baking dough is controlled at 1075-1100℃.

[0035] Based on the aforementioned scheme, the preferred option is to further limit the raw materials of the green body in step S1 to: 32-33 parts of premium kaolin, 52-54 parts of potassium feldspar, 11-13 parts of ultrafine quartz, 6-7 parts of alumina powder, 3 parts of whitening agent, and 4 parts of plasticizer.

[0036] A further preferred embodiment of the aforementioned scheme is that the amount of alumina powder added is further limited to 6% of the total mass of the raw material.

[0037] The beneficial effects of this invention are as follows:

[0038] 1. This invention, by setting up a turntable, a sliding ball, and other structures, facilitates the placement of the lamp blank on the turntable. By rotating the turntable, the circumferential sidewall of the lamp blank comes into contact with the scraper mechanism, thereby avoiding uneven cutting and improving the cutting effect. In addition, due to the use of a cyclone-shaped elastic sheet, by rotating the central rotating rod and under the limitation of the annular fixed seat, one end of the elastic sheet moves away from the central rotating rod, thereby causing the arc-shaped support plate to expand outward. After the central rotating rod rotates to a certain extent, the arc-shaped support plate contacts and supports the inner wall of the lamp blank to achieve a fixing effect. This design can adapt to lamp blanks of different sizes, ensuring the versatility of the equipment.

[0039] 2. By setting up structures such as one-way stoppers, sliding cylinders, and sliding rods, one end of the one-way stopper can extend into the annular gear seat. When the central rotating rod rotates, the hollow roller slides on the tooth surface of the annular gear seat under the guidance of the annular gear seat, and the sliding rod slides in the sliding cylinder under the deformation of the sliding rod spring. Thus, the connecting ring can rise and fall to match the sliding of the hollow roller. When the central rotating rod rotates in the restricted direction, the hollow roller blocks one side of the tooth surface of the annular gear seat, thereby cooperating with the annular gear seat to form a one-way restriction on the rotation direction of the central rotating rod, effectively preventing the elastic plate from rebounding. By setting up hollow rollers, the restriction effect is ensured while improving the smoothness of the rotation of the central rotating rod.

[0040] 3. By setting up a spiral spring, the one-way stop can be disengaged from the ring tooth seat by pressing down the pedal, and then the central rotating rod and handle can be reset under the action of the spiral spring. The operation is simple and reliable, improving practicality. By setting up a hollow rubber strip, the deformation of the hollow rubber strip can increase the friction between the curved support plate and the lamp blank when the curved support plate contacts the inner wall of the lamp blank, thereby improving the fixing effect and ensuring reliability.

[0041] 4. By setting up lifting knobs, horizontal adjustment knobs, angle adjustment knobs, etc., the scraper can be easily adjusted in multiple directions, thus making it adaptable to lamp blanks of different shapes and sizes, improving its flexibility and versatility.

[0042] 5. By setting up structures such as limiting airbags and elastic sleeves, the volume of the limiting airbag can be adjusted by adjusting the airbag, thereby changing the distance between the lifting block and the sliding plate. With the cooperation of the elastic sleeve deformation buffer, the scraper can fully contact the outer wall of the lamp blank, thereby improving the reliability of cutting. Since the limiting airbag is adjustable, it can better meet the user's needs.

[0043] 6. By setting up pressure sensing components and pressure gauges, the force between the scraper and the outer wall of the lamp blank can be intuitively understood, which facilitates better adjustment by adjusting the airbag and improves practicality; by setting up scraper seats, dust collection devices and other structures, the waste scraped off by the scraper can be collected and processed in real time, improving environmental protection and practicality.

[0044] 7. By setting up a brush head, the lamp blank can be rotated based on the turntable, and the surface of the lamp blank can be wiped simultaneously, improving the cleanliness of the lamp blank and facilitating further processing; by setting up a cleaning spring and a ring plate, the cleaning force of the brush head can be enhanced, thereby improving the cleaning effect.

[0045] 8. By setting up structures such as cleaning rollers, cleaning airbags, and arc-shaped brushes, the arc-shaped brushes can contact and clean the surface of the lamp blank when it rotates. Since the arc-shaped brushes are arc-shaped, they can effectively avoid scratching the surface of the lamp blank.

[0046] 9. The cleaning airbag can be adjusted in size to accommodate lamp blanks of different sizes. In addition, the cleaning airbag can also relieve pressure, preventing excessive force between the curved brush blade and the lamp blank, which could damage the lamp blank. Furthermore, since the cleaning roller rotates on the annular protrusion, the pressure relief capability is further enhanced, ensuring the cleaning effect while improving the protection of the lamp blank.

[0047] 10. By setting up arc-shaped brush blades, cleaning brushes, and concave brush plates, the corresponding structure can be selected for cleaning according to needs, adapting to different lamp blanks and improving selectivity and flexibility of use. Attached Figure Description

Therefore, they should not be construed as limitations on this patent.

[0064] In the description of this patent, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integral connection or setting. Those skilled in the art can understand the specific meaning of the above terms in this patent according to the specific circumstances.

[0065] Example 1:

[0066] A type of equipment for molding ceramic lamps for fire evacuation, such as Figure 1-7 As shown, the device includes a base 1 and a turntable 4 for supporting the lamp blank 5. An annular slide block 2 is fixed to the top outer wall of the base 1 by screws. Four or more evenly distributed circumferential sliding rods 24 are fixed to the bottom outer wall of the turntable 4 by screws. The bottom outer wall of each sliding rod 24 is slidably connected to the top inner wall of the annular slide block 2. A mounting bracket 11 is fixed to the top outer wall of the base 1 by screws. A scraper mechanism is mounted on one side of the mounting bracket 11. A positioning mechanism for positioning the lamp blank 5 is provided on the turntable 4. The positioning mechanism includes a central rotating rod 21 and four or more arc-shaped support plates 23. The central rotating rod 21 is rotatably connected to the inner wall of the turntable 4, and the central rotating rod 21 coincides with the central axis of the turntable 4. Elastic plates 20 are welded between the inner wall of the arc-shaped support plate 23 near the central rotating rod 21 and the outer circumferential wall of the central rotating rod 21. An annular sliding rod 24 is fixed to the top outer wall of the turntable 4 by screws. The fixed seat 19 has an elastic plate 20 that slides through the inner wall of the annular fixed seat 19, forming a cyclone-shaped structure. The top side wall of the central rotating rod 21 is fixed with a handle 22 by screws. By setting up a turntable 4, a sliding ball rod 24, and other structures, the lamp blank 5 can be easily placed on the turntable 4. By rotating the turntable 4, the circumferential side wall of the lamp blank 5 can be made to contact the scraper mechanism, thereby avoiding uneven cutting and improving the cutting effect. In addition, due to the use of the cyclone-shaped elastic plate 20, by rotating the central rotating rod 21, under the limitation of the annular fixed seat 19, one end of the elastic plate 20 moves away from the central rotating rod 21, thereby causing the arc-shaped support plate 23 to expand outward. After the central rotating rod 21 rotates to a certain extent, the arc-shaped support plate 23 contacts and supports the inner wall of the lamp blank 5 to achieve a fixing effect. This design can adapt to lamp blanks 5 of different sizes, ensuring the versatility of the equipment.

[0067] To prevent the elastic sheet from rebounding 20; such as Figure 3-5 As shown, the outer circumference of the central rotating rod 21 is fixed with an annular gear seat 35 by screws. The bottom outer wall of the turntable 4 is fixed with four or more slide cylinders 33 by screws. Each slide cylinder 33 has a slide rod 30 slidably connected to its inner wall. A single slide rod spring 27 is welded between the top outer wall of the slide rod 30 and the top inner wall of the slide cylinder 33. The bottom end of the slide rod 30 is fixed with a single connecting ring 26 by screws. Two or more equidistant one-way stops 28 are fixed to the inner circumference of the connecting ring 26 near the central rotating rod 21 by screws. The one-way stops 28 are adapted to the annular gear seat 35. A hollow roller 34 is rotatably installed on the outer wall of one end of the one-way stops 28 near the annular gear seat 35. A foot rod 32 is fixed to one side of the outer wall of the connecting ring 26 by screws. A pedal 3 is integrally provided at one end of the foot rod 32. By setting up structures such as one-way stop 28, slide cylinder 33 and slide rod 30, one end of the one-way stop 28 can be inserted into the annular gear seat 35. When the central rotating rod 21 rotates, the hollow roller 34 slides on the tooth surface of the annular gear seat 35 under the guidance of the annular gear seat 35. The slide rod 30 slides in the slide cylinder 33 under the deformation of the slide rod spring 27. As a result, the connecting ring 26 can rise and fall to match the sliding of the hollow roller 34. When the central rotating rod 21 rotates in the restricted direction, the hollow roller 34 blocks one side of the tooth surface of the annular gear seat 35, thus cooperating with the annular gear seat 35 to form a one-way restriction on the rotation direction of the central rotating rod 21, effectively preventing the elastic plate 20 from rebounding. By setting the hollow roller 34, the restriction effect is ensured while improving the smoothness of the rotation of the central rotating rod 21.

[0068] To facilitate the reset of the central rotating rod 21; such as Figure 4 , Figure 5 As shown, the outer wall of the slider 24 near the central rotating rod 21 is fixed with the same connecting frame 31 by screws. The top outer wall of the connecting frame 31 is integrally provided with a convex ring, which is located outside the bottom end of the central rotating rod 21 and is concentric with the central rotating rod 21. The bottom side wall of the central rotating rod 21 and the inner wall of the convex ring of the connecting frame 31 are welded with the same spiral spring 29. By setting the spiral spring 29, the one-way stop 28 can be disengaged from the annular tooth seat 35 by pressing down the pedal 3, and then the central rotating rod 21 and the handle 22 can be reset under the action of the spiral spring 29. The operation is simple and reliable, and the practicality is improved.

[0069] To improve the fixation effect; such as Figure 4 As shown, two or more hollow adhesive strips 25 are embedded in the outer wall of one side of the arc-shaped support plate 23. By setting the hollow adhesive strips 25, when the arc-shaped support plate 23 contacts the inner wall of the lamp blank 5, the deformation of the hollow adhesive strips 25 can increase the friction between the support plate 23 and the lamp blank 5, thereby improving the fixing effect and ensuring reliability.

[0070] To facilitate the cutting of leftover material and rough edges; such as Figure 2 , Figure 6 , Figure 7 As shown, the scraper mechanism includes a scraper 44 and a scraper seat 13. The same lifting screw 12 is rotatably mounted on the inner walls of both sides of the mounting bracket 11. The top end of the lifting screw 12 passes through the mounting bracket 11 and is fixed with a lifting knob 15 by screws. The lifting screw 12 is threadedly connected to a lifting block 14. An adjusting seat 36 is mounted on one outer wall of the lifting block 14 via a pressure adjusting mechanism. An adjusting rod 41 is slidably connected to the inner wall of one end of the adjusting seat 36, and a horizontal adjusting knob 40 for fixing the adjusting rod 41 is threadedly connected to the inner wall of the top of the adjusting seat 36. A rotating rod 43 is rotatably connected to the inner wall of one end of the adjusting rod 41. An angle adjustment knob 42 for fixing the rotating rod 43 is threadedly connected to the top inner wall of one end of the adjusting rod 41. The scraper 44 is fixed to the outer wall of one side of the scraper seat 13 by screws, and the outer wall of one end of the rotating rod 43 is fixed to the outer wall of the other side of the scraper seat 13 by screws. By setting up structures such as the lifting knob 15, the horizontal adjustment knob 40, and the angle adjustment knob 42, the scraper 44 can be easily adjusted in multiple directions, so that it can adapt to lamp blanks 5 of different shapes and sizes, improving flexibility and versatility.

[0071] For ease of adjustment; such as Figure 6 , Figure 7 As shown, the pressure regulating mechanism includes an elastic rubber sleeve 37 and a limiting airbag 38. A guide post 45 is provided on one side of the regulating seat 36. One end of the guide post 45 is fixed to a rubber sleeve mounting plate by screws. A guide seat 46 is slidably connected to the outer wall of the guide post 45, and a sliding plate 47 is slidably connected to the outer wall of the guide seat 46. The outer walls of both ends of the elastic rubber sleeve 37 are respectively bonded to one side of the outer wall of the sliding plate 47 and one side of the outer wall of the rubber sleeve mounting plate. The limiting airbag 38 is fitted over the guide seat 46, and the guide seat 46 is located between the lifting block 14 and the sliding plate 47. The top outer wall of the 38 is connected to an adjustable airbag 9 with an air valve via an air pipe 39. The adjustable airbag 9 is fixed to the outer wall of one side of the mounting bracket 11 by a buckle. By setting up structures such as the limiting airbag 38 and the elastic sleeve 37, the volume of the limiting airbag 38 can be adjusted by the adjustable airbag 9, thereby changing the distance between the lifting block 14 and the sliding plate 47. With the cooperation of the deformation buffer of the elastic sleeve 37, the scraper 44 can fully contact the outer wall of the lamp blank 5, thereby improving the reliability of cutting. Since the limiting airbag 38 is adjustable, it can better meet the user's needs.

[0072] To improve practicality; such as Figure 1 , Figure 7As shown, a pressure sensing component 49 is installed between the outer wall of one end of the adjusting seat 36 and the outer wall of one side of the rubber sleeve mounting plate. The pressure sensor in the pressure sensing component 49 can be a PT124G-111. A pressure gauge 48 is fixed to one side of the outer wall of the adjusting seat 36 by screws. The pressure gauge 48 is electrically connected to the pressure sensing component 49. By setting the pressure sensing component 49 and the pressure gauge 48, the force between the scraper 44 and the outer wall of the lamp blank 5 can be intuitively understood, which facilitates better adjustment by adjusting the airbag 9 and improves practicality.

[0073] To facilitate waste collection; such as Figure 2 , Figure 6 As shown, the scraper seat 13 has a cover-shaped structure, and the inner wall of one side of the scraper seat 13 is tangent to the outer wall of one side of the scraper 44. A dust collection device 18 is provided on the top outer wall of the base 1, and the bottom outer wall of the scraper seat 13 is open. The negative pressure pipe 10 is connected to the input end of the dust collection device 18. By setting up the scraper seat 13, the dust collection device 18 and other structures, the waste scraped off by the scraper 44 can be collected and processed in real time, which improves environmental protection and practicality.

[0074] To facilitate cleaning the surface of lamp blank 5; such as Figure 1 , Figure 2 As shown, a cleaning rack 6 is fixed to the top outer wall of the base 1 by screws. A cleaning rod 17 is slidably connected to the inner wall of one side of the cleaning rack 6. A brush head 16 is provided on the outer wall of the cleaning rod 17 near the lamp blank 5. By setting the brush head 16, the lamp blank 5 can be rotated based on the turntable 4, and the surface of the lamp blank 5 can be wiped simultaneously to improve the cleanliness of the lamp blank 5 and facilitate further processing.

[0075] To improve cleaning effectiveness; such as Figure 1 As shown, the outer wall of the cleaning rod 17 is fixed with an annular plate 8 by screws, and a cleaning spring 7 is welded between one side of the outer wall of the annular plate 8 and one side of the outer wall of the cleaning frame 6. By setting the cleaning spring 7 and the annular plate 8, the cleaning force of the brush head 16 can be enhanced, thereby improving the cleaning effect.

[0076] In this embodiment, the user places the lamp blank 5 to be processed on the turntable 4 and rotates the central rotating rod 21 by rotating the handle 22. Under the limitation of the annular fixing seat 19, one end of the elastic piece 20 moves away from the central rotating rod 21, thereby causing the arc-shaped support plate 23 to expand outward. After the central rotating rod 21 rotates to a certain extent, the arc-shaped support plate 23 contacts and supports the inner wall of the lamp blank 5 to achieve the effect of fixing the lamp blank 5. The user rotates the turntable 4 to make the circumferential side wall of the lamp blank 5 contact the scraper mechanism, thereby avoiding uneven cutting. The uniformity of the cutting process improves the cutting effect. During the rotation of the central rotating rod 21, the hollow roller 34 slides on the tooth surface of the annular toothed seat 35 under the guidance of the annular toothed seat 35. The slide rod 30 slides inside the slide cylinder 33 under the deformation of the slide rod spring 27, thereby allowing the connecting ring 26 to rise and fall in coordination with the sliding of the hollow roller 34. When the central rotating rod 21 rotates in the restricted direction, the hollow roller 34 blocks one side of the tooth surface of the annular toothed seat 35, thus cooperating with the annular toothed seat 35 to form a unidirectional restriction on the rotation direction of the central rotating rod 21. To prevent the elastic sheet 20 from rebounding; when the lamp blank 5 needs to be removed, the one-way stop 28 can be disengaged from the annular toothed seat 35 by pressing down the pedal 3, and then the central rotating rod 21 and the rotating handle 22 can be reset under the action of the spiral spring 29. In addition, by setting up structures such as the lifting knob 15, the horizontal adjustment knob 40, and the angle adjustment knob 42, the scraper 44 can be easily adjusted in multiple directions, so that it can adapt to lamp blanks 5 of different shapes and sizes. By setting up structures such as the limiting airbag 38 and the elastic rubber sleeve 37, the scraper 44 can be adjusted in multiple directions. The volume of the limiting airbag 38 can be adjusted by adjusting the airbag 9, thereby changing the distance between the lifting block 14 and the sliding plate 47. With the cooperation of the elastic rubber sleeve 37 deformation buffer, the scraper 44 can fully contact the outer wall of the lamp blank 5, thereby improving the reliability of cutting. Since the limiting airbag 38 is adjustable, it can better meet the user's needs. By setting the brush head 16, the lamp blank 5 can be rotated based on the turntable 4, and the surface of the lamp blank 5 can be wiped simultaneously, improving the cleanliness of the lamp blank 5 and facilitating further processing.

[0077] Example 2:

[0078] A type of equipment for molding ceramic lamps for fire evacuation, such as Figure 8 , Figure 9As shown, in order to better clean the surface of the lamp blank 5, this embodiment makes the following improvements based on embodiment 1: A cleaning frame 6 is fixed to the top outer wall of the base 1 by screws. A cleaning rod 50 is adjustablely inserted and fixed to the inner wall of one side of the cleaning frame 6. The outer circumference of the cleaning rod 50 is integrally provided with equally spaced annular protrusions 53. A cleaning roller 54 is rotatably connected to the outer wall of the annular protrusions 53. A cleaning airbag 51 with an air valve is sleeved and fixed to the outer wall of the cleaning roller 54. Evenly distributed arc-shaped brushes 52 are adhered to the outer circumference of the cleaning airbag 51. The arc-shaped brushes 52 are adapted to the position of the outer wall of the lamp blank 5. By setting the cleaning roller 54, The cleaning airbag 51 and the arc-shaped brush 52, among other structures, enable the arc-shaped brush 52 to contact and clean the surface of the lamp blank 5 when it rotates. Because the arc-shaped brush 52 is arc-shaped, it can effectively prevent scratches on the surface of the lamp blank 5. The cleaning airbag 51 can be adjusted in size to accommodate lamp blanks of different sizes. In addition, the cleaning airbag 51 can also relieve pressure, preventing excessive force at the contact point between the arc-shaped brush 52 and the lamp blank 5 from damaging the lamp blank 5. Furthermore, since the cleaning roller 54 rotates on the annular protrusion 53, the pressure relief capability is further enhanced, ensuring the cleaning effect while improving the protection of the lamp blank 5.

[0079] Example 3:

[0080] A type of equipment for molding ceramic lamps for fire evacuation, such as Figure 8 , Figure 9 As shown, in order to more selectively clean the surface of the lamp blank 5, this embodiment makes the following improvements based on embodiment 1: A cleaning frame 6 is fixed to the top outer wall of the base 1 by screws. A cleaning rod 50 is adjustablely inserted and fixed to the inner wall of one side of the cleaning frame 6. The outer circumference of the cleaning rod 50 is integrally provided with equidistantly distributed annular protrusions 53. The outer wall of the annular protrusions 53 is rotatably connected to a cleaning roller 54 through a damping slip ring 57. A cleaning airbag 51 with an air valve is sleeved and fixed to the outer wall of the cleaning roller 54. An arc-shaped brush 52, a cleaning brush 55, and a concave brush plate 56 are sequentially bonded to the outer circumference of the cleaning airbag 51. The concave brush plate 56 is adapted to the outer circumference of the lamp blank 5. By setting the arc-shaped brush 52, the cleaning brush 55, and the concave brush plate 56, the corresponding structure can be selected for cleaning according to the needs, so as to adapt to different lamp blanks 5, improving selectivity and flexibility of use.

[0083] S1: The raw materials for the blank are divided by weight, and after being slurried, they are prepared into clay strips;

[0084] S2: Vacuum refining of the prepared material;

[0085] S3: The clay strips after vacuum roughing are extruded and refined a second time using a vacuum pug mill;

[0086] S4: Cut the obtained clay into a stainless steel mold as needed;

[0087] S5: The steel mold containing the mud is conveyed to the roller pressing equipment for pressing;

[0088] S6: After pressing, the steel mold is placed in the baking room to bake the blank, and then it is demolded to obtain lamp blank 5;

[0089] S7: The lamp blank 5 is processed by the fire evacuation ceramic lamp forming equipment described in Example 1, Example 2 or Example 3;

[0090] S8: The processed lamp blank 5 is sequentially subjected to glazing, printing, and glazing firing to obtain the ceramic lamp product;

[0091] S9: Ceramic lamp products are packaged in different grades.

[0092] In step S1, the raw materials for the green body, by weight, include 30-35 parts of premium kaolin, 50-55 parts of potassium feldspar, 10-15 parts of ultrafine quartz, 5-7.5 parts of alumina powder, 2-3 parts of whitening agent, and 3-5 parts of plasticizer.

[0093] In step S1, the composition of the raw material for the billet is controlled as follows: SiO2 64.30%, Al2O3 17-20%, Fe2O3 <0.1%, CaO 0.45-0.75%, MgO 0.25-0.4%, TiO2 <0.05%, K2O 6-7%, Na2O 1-1.5%, and other 2-3%, with the loss on ignition controlled at 5-6%.

[0094] The amount of alumina powder added accounts for 4.5% to 7% of the total mass of the raw material.

[0095] In step S3, the rotational speed of the extrusion shaft of the vacuum pumice machine is controlled at 20-25 r / min, and the vacuum degree is controlled at 98% or higher.

[0096] In step S6, when baking the blanks in the baking room, the blanks are wrapped with fire-resistant paper before baking. The baking temperature is controlled at 1050-1125℃, and the blanks are kept warm for 2-3 hours after baking.

[0097] In step S8, before glazing, the processed lamp blank 5 needs to be washed with water by a brake washing machine, and the washed lamp blank 5 is sent to the baking room for secondary baking. After secondary baking, the glazing operation is carried out.

[0098] In step S8, the temperature of the second baking blank is controlled at 1075-1100℃.

[0102] To ensure the product's heat dissipation performance, the proportion of alumina powder in the raw materials was changed while keeping other conditions unchanged. After production, a heat dissipation test was conducted, and the temperature drop of the lampshade surface per unit time was recorded. The following data was obtained:

[0103] Alumina powder addition ratio 4.5％ 5.0％ 5.5％ 6.0％ 6.5％ 7.0％ Temperature drop per unit time 5.6℃ 7.9℃ 9.8℃ 10.5℃ 10.3℃ 9.6℃

[0104] As can be seen from the above, when the alumina powder content accounts for 6 to 6.5% of the total raw material, the ceramic lamp has excellent heat dissipation capacity, and when the alumina powder content is 6%, the ceramic lamp has the best heat dissipation capacity. Therefore, the preferred alumina powder content is 6%.
