[0027] Furthermore: in the step S1, the composition of the green body raw material is controlled to be: 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%, and the loss on ignition is controlled at 5-6%.

[0035] The beneficial effects of the present invention are:

[0036] 1. The present invention provides a turntable, a sliding ball rod and other structures, which can facilitate the placement of the lamp blank on the turntable, and the circumferential side wall of the lamp blank is brought into contact with the scraper mechanism by rotating the turntable, thereby avoiding uneven cutting and improving the cutting effect. In addition, due to the use of a whirlwind-shaped elastic sheet, by rotating the center rotating rod, one end of the elastic sheet is moved away from the center rotating rod under the limitation of the annular fixed seat, so that the arc support plate expands outward. After the center rotating rod rotates to a certain extent, the arc 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.

[0037] 2. By setting structures such as a one-way stop column, a slide cylinder and a slide rod, one end of the one-way stop column can be extended into the annular gear seat. When the center 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 slide rod slides in the slide cylinder under the deformation of the slide rod spring, so that the connecting ring can rise and fall to cooperate with the sliding of the hollow roller. When the center 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 the effect of one-way restriction of the rotation direction of the center rotating rod, effectively avoiding the rebound of the elastic sheet. By setting the hollow roller, the restriction effect is guaranteed while improving the smoothness of the rotation of the center rotating rod.

[0038] 3. By setting a spiral spring, the one-way stop column can be separated from the annular gear seat by pressing down the pedal, and then the center rotating rod and the rotating handle can be reset under the action of the spiral spring. The operation is simple and reliable, which improves practicality. By setting a hollow rubber strip, when the arc-shaped support plate contacts the inner wall of the lamp blank, the deformation of the hollow rubber strip can be used to increase the friction between the arc-shaped support plate and the lamp blank, thereby improving the fixing effect and ensuring reliability.

[0039] 4. By setting up structures such as the lifting knob, the horizontal adjustment knob, and the angle adjustment knob, the scraper can be easily adjusted in multiple directions, so that it can adapt to lamp blanks of different shapes and sizes, thereby improving flexibility and versatility.

[0040] 5. By setting up structures such as a limiting airbag and an elastic rubber sleeve, the volume of the limiting airbag can be adjusted by using the adjusting airbag, thereby changing the distance between the lifting block and the sliding plate, and with the cooperation of the deformation buffer of the elastic rubber sleeve, 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.

[0041] 6. By setting up a pressure sensing component and a pressure gauge, the force between the scraper and the outer wall of the lamp blank can be intuitively understood, which is conducive to better adjustment by adjusting the airbag and improving practicality; by setting up a scraper seat, a dust suction device and other structures, the waste scraped by the scraper can be collected and processed in real time, improving environmental protection and practicality.

[0042] 7. By setting up a brush head, the lamp blank can be driven to rotate based on the turntable, and the surface of the lamp blank can be wiped simultaneously, thereby improving the cleanliness of the lamp blank and facilitating further processing; by setting up a cleaning spring and annular plate, the cleaning force of the brush head can be enhanced, thereby improving the cleaning effect.

The fixed seat 19 and the elastic sheet 20 slide through the inner wall of the annular fixed seat 19, and the elastic sheet 20 forms a whirlwind structure; the top side wall of the central rotating rod 21 is fixed with a rotating handle 22 by a screw; by setting the turntable 4, the sliding ball rod 24 and other structures, it is convenient to place the lamp blank 5 on the turntable 4, and the circumferential side wall of the lamp blank 5 is brought into contact with the scraper mechanism by rotating the turntable 4, thereby avoiding the phenomenon of uneven cutting and improving the cutting effect. In addition, due to the use of the whirlwind-shaped elastic sheet 20, by rotating the central rotating rod 21, under the limit of the annular fixed seat 19, one end of the elastic sheet 20 is moved away from the central rotating rod 21, so that the arc support plate 23 expands outward. After the central rotating rod 21 rotates to a certain extent, the arc 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] When using this embodiment, the user places the lamp blank 5 to be processed on the turntable 4, and rotates the central rotating rod 21 by the turning handle 22. Under the limit of the annular fixing seat 19, one end of the elastic sheet 20 is moved away from the central rotating rod 21, so that the arc-shaped support plate 23 expands 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 so that the circumferential side wall of the lamp blank 5 contacts the scraper mechanism, thereby avoiding uneven cutting. The phenomenon of uniformity improves the cutting effect; in the process of rotating the central rotating rod 21, the hollow roller 34 slides on the tooth surface of the annular tooth seat 35 under the guidance of the annular tooth seat 35, and the slide bar 30 slides in the slide cylinder 33 under the deformation of the slide bar spring 27, so that the connecting ring 26 can rise and fall to cooperate 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 tooth seat 35, thereby cooperating with the annular tooth seat 35 to form a one-way restriction on the rotation direction of the central rotating rod 21. When the lamp blank 5 needs to be removed, the pedal 3 can be pressed down to disengage the one-way blocking column 28 from the annular gear seat 35, 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 the lifting knob 15, the horizontal adjustment knob 40, the angle adjustment knob 42 and other structures, the scraper 44 can be adjusted in multiple directions, so that it can adapt to lamp blanks 5 of different shapes and sizes. By setting the limiting airbag 38, the elastic rubber sleeve 37 and other structures, The volume of the limiting airbag 38 can be adjusted by using the adjusting airbag 9, thereby changing the distance between the lifting block 14 and the sliding plate 47, and with the cooperation of the deformation buffer of the elastic rubber 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 usage needs; by setting the brush head 16, the lamp blank 5 can be driven to rotate based on the turntable 4, and the surface of the lamp blank 5 can be wiped synchronously, thereby improving the cleanliness of the lamp blank 5 and facilitating further processing.

[0070] S1: Take the green body raw materials according to weight, slurry them and prepare them into mud strips;

[0071] S2: vacuum refining the prepared product;

[0072] S3: The vacuum-refined mud strips are subjected to secondary extrusion and mud making by a vacuum mud making machine;

[0073] S4: Cut the obtained clay into stainless steel molds as needed;

[0074] S5: transporting the steel mold containing the clay material to the roller pressing equipment for pressing;

[0075] S6: The pressed steel mold is placed in a baking room to bake the blank and then demoulded to obtain a lamp blank 5;

[0076] S7: Processing the lamp blank 5 through the fire evacuation ceramic lamp forming equipment described in Example 1;

[0077] S8: performing glaze pouring, printing, and glaze firing on the processed lamp blank 5 in sequence to obtain a ceramic lamp product;

[0078] S9: Grading and packaging of ceramic lamp products.

[0079] In the step S1, the raw materials for the green body include, by weight, 30 to 35 parts of special kaolin, 50 to 55 parts of potassium feldspar, 10 to 15 parts of ultrafine quartz, 5 to 7.5 parts of alumina powder, 2 to 3 parts of whitening agent, and 3 to 5 parts of plasticizer.

[0080] In step S1, the composition of the green body raw material is controlled to be: 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%, and the loss on ignition is controlled at 5-6%.

[0081] The amount of the aluminum oxide powder added is 4.5-7% of the total mass of the green body raw material.

[0082] Wherein, in the step S3, the rotation speed of the extrusion rotating shaft of the vacuum clay extruder is controlled at 20-25 r / min, and the vacuum degree is controlled at above 98%.

[0083] Among them, in the step S6, when baking the dough in the baking room, the dough is wrapped with fire-resistant paper and then baked. The temperature of the dough is controlled at 1050-1125° C. and is kept warm for 2-3 hours after baking.

[0084] Among them, in the 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 a baking room for secondary baking, and then the glazing operation is performed after the secondary baking.

[0085] Wherein, in the step S8, the temperature of the secondary baked dough is controlled at 1075-1100°C.

[0086] Among them, the green body raw materials in the step S1 are further limited to: 32-33 parts of special 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.

[0087] The amount of alumina powder added is further limited to 6% of the total mass of the green body raw material.

[0088] Experiment 1:

[0089] In order to ensure the heat dissipation performance of the product, the proportion of alumina powder in the raw materials was changed while other conditions remained 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:

[0090] 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℃

[0091] From the above, it can be seen that when the alumina powder addition ratio accounts for 6-6.5% of the total raw material ratio, the ceramic lamp has excellent heat dissipation capacity, and when the alumina powder addition ratio is 6%, the ceramic lamp has the best heat dissipation capacity. Therefore, the alumina powder addition ratio is preferably 6%.
