The terms "vertical", "horizontal", "left", "right", "top", "bottom", "bottom", "top" and similar expressions used herein are for Not meant to be the only implementation.

Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field to which this application belongs. The terms used herein in the specification of the present application are for the purpose of describing particular embodiments only, and are not intended to limit the present application. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

The embodiment of the present application discloses a method for removing slag from a green ceramic tape. The casting machine 100 is used to produce a green ceramic tape. For a plurality of green ceramic tapes, the green ceramic tapes in this application refer to the green ceramic tapes cut by the casting machine 100 . The green ceramic belt slag cleaning method disclosed in the present application comprises the following steps:

S110, cooling the green ceramic tape to a first temperature;

During the process of cooling the green ceramic belt to the first temperature, the slag on the green ceramic belt is also cooled at the same time. When the green ceramic belt is cooled to the first temperature, the viscosity between the cooled slag and the cooled green ceramic belt decreases, so that the slag falls off from the green ceramic belt, which facilitates subsequent cleaning of the slag. In this step, the first temperature is a technical parameter. When the green ceramic tape is cooled to the first temperature, the predetermined characteristics of the green ceramic tape will not be damaged, and the viscosity between the slag and the green ceramic tape can be reduced. .

Preferably, the first temperature can be 5°C to 20°C. Within this temperature range, the viscosity between the slag and the green ceramic tape is low, and the predetermined characteristics of the green ceramic tape will not be damaged, so as to avoid the failure of cooling due to insufficient cooling. The viscosity between the slag and the green ceramic tape is not reduced, or excessive cooling is avoided to damage the intended properties of the green ceramic tape.

Preferably, the green ceramic tape can be cooled to the first temperature by cold air, the cooling effect by cold air is good, the process is simple, and the implementation cost is low. Further, a dust filter can be installed at the outlet of the cold air to avoid dust being carried in the cold air used to cool the green ceramic belt, and to avoid blowing dust to the green ceramic belt during the cooling process, causing secondary pollution of the green ceramic belt, Prevent more dust on the green ceramic tape.

S120, eliminating static electricity of the cooled green ceramic tape;

The green ceramic belt will carry a certain amount of static electricity during the production process and in step S110, so that the slag is adsorbed on the green ceramic belt through electrostatic adsorption force. Reduce the degree of adhesion between the slag and the green ceramic belt, so that the material slag can fall off from the green ceramic belt more easily, which is convenient for subsequent cleaning of the material slag.

S130, blowing high-pressure gas to the green ceramic belt after the static electricity has been eliminated, and sucking the high-pressure gas blown to the green ceramic belt, the moving direction of the green ceramic belt on the casting machine 100 is the first direction, and the blowing direction of the high-pressure gas Opposite to the first direction, so that the high pressure gas is blown back to the green ceramic belt, the high pressure gas can blow up the slag on the green ceramic belt, and the high pressure gas blown back to the green ceramic belt takes away the material on the green ceramic belt. After the slag is sucked, the slag is prevented from falling everywhere, thereby removing the slag on the green ceramic belt. The method of backflushing can avoid high-pressure gas blowing the slag to the green ceramic belt that has been removed, resulting in secondary pollution of the green ceramic belt.

Preferably, the pressure of the high-pressure gas can be 0.3Mpa to 1.5Mpa. Within this pressure range, the high-pressure gas can blow up the slag on the green ceramic belt, and then be sucked away to avoid low pressure and The slag on the green ceramic belt cannot be blown up, which causes the slag to continue to adhere to the green ceramic belt, preventing the poor removal effect of the material slag. Or avoid blowing away the slag due to high air pressure. Part of the high-pressure gas escapes and is not taken away by suction, causing the slag to fall everywhere, and then continue to fall on the green ceramic belt, causing secondary pollution of the green ceramic belt. At the same time, avoid high air pressure and damage the green ceramic tape, resulting in rupture or damage of the green ceramic tape.

S140 , heating the green ceramic tape with hot air, the heated green ceramic tape has better flexibility and is convenient for winding, preventing the green ceramic tape from being broken due to poor flexibility due to cooling in step S110 when the green ceramic tape is being wound.

Preferably, the temperature of the hot air can be 30°C to 40°C. Too high or too low temperature will affect the winding process of the green ceramic tape.

Further, a dust filter can be installed at the hot air outlet to avoid dust being carried in the hot air, to avoid blowing dust to the green ceramic belt, causing secondary pollution of the green ceramic belt, and preventing more dust on the green ceramic belt. .

In a method for removing slag from a green ceramic belt disclosed in the embodiments of the present application, the green ceramic belt is first cooled, and when the green ceramic belt is cooled to a first temperature, the slag after cooling and the cooled green ceramic belt are separated from each other. The viscosity decreases, the slag falls off from the green ceramic belt, and then the electrostatic adsorption force between the material slag and the green ceramic belt is eliminated through the electrostatic removal step, so as to further reduce the degree of adhesion between the material slag and the green ceramic belt, so that the material slag can be eliminated. It is easier to fall off from the green ceramic belt, and finally the high-pressure gas can blow up the slag on the green ceramic belt, and the high-pressure gas blown back to the green ceramic belt takes away the slag on the green ceramic belt. Thereby, the slag on the green ceramic belt is removed, and suction is performed at the same time, and the high-pressure gas carrying the slag is sucked away, so as to prevent the slag from falling everywhere, and prevent the slag from continuing to fall on the green ceramic belt, thereby avoiding the occurrence of raw material. The secondary pollution of the ceramic belt, and the way of back blowing can prevent the high-pressure gas from blowing the slag to the green ceramic belt that has been removed, thereby avoiding the secondary pollution of the green ceramic belt.

It can be seen that the above-mentioned slag cleaning method for the green ceramic belt has excellent removal effect. Compared with the purging mechanism in the prior art, the slag cleaning method disclosed in the present application can remove the slag that is relatively firmly adhered to the green ceramic belt, and can not only eliminate the The slag scattered on the surface of the green ceramic belt can also eliminate the slag adhering to the green ceramic belt, and by avoiding blowing up the surrounding material slag and dust during cleaning, it can prevent the slag from continuing to fall on the green ceramic belt. Therefore, the secondary pollution of the green ceramic belt is caused, thereby preventing the slag and dust from affecting the quality of the green ceramic belt, improving the quality of the green ceramic belt, and further improving the yield of the green ceramic belt.

The technical solutions and technical effects of the present application are further described below through specific comparative experimental examples. It should be noted that the following comparative experimental examples are only for further explanation of the present application and do not limit the technical solutions of the present application.

Set up the following comparison experiments:

Comparative Example 1: 200 green ceramic sheets without dust removal and slag removal were randomly selected. The size of the single-layer substrate obtained after sintering the green ceramic sheets was all 12cm×12cm. The appearance of the single-layer substrate was inspected under a 6000K white LED lamp. Point defects caused by slag such as porcelain buds, pits, etc., and the proportion of defective single-layer substrates in 200 single-layer substrates. The green ceramic sheets produced in the same batch were laminated and sintered to obtain a laminated substrate (2 green ceramic sheets laminated), 200 laminated substrates were randomly selected, and the slag shadow inside the laminated substrate was inspected under a 6000K white LED lamp. , and count the proportion of the 200 laminated substrates with slag shadows.

Comparative Example 2: A purging mechanism is set at the discharge end of the green ceramic sheets of the casting machine, and the green ceramic sheets are blown by high-pressure gas, and 200 green ceramic sheets obtained through the above process are randomly selected. The size of the layered substrates are all 12cm×12cm. Under the 6000K white light LED lamp, the point defects caused by the apparent porcelain buds, pits and other slag of the single-layer substrates are inspected, and the 200 single-layer substrates with defects in the single-layer substrates are counted. proportion. The green ceramic sheets produced in the same batch were laminated and sintered to obtain a laminated substrate (2 green ceramic sheets laminated), 200 laminated substrates were randomly selected, and the slag shadow inside the laminated substrate was inspected under a 6000K white LED lamp. , and count the proportion of the 200 laminated substrates with slag shadows.

Comparative Example 3: 200 pieces of green ceramic sheets after the dust removal and slag removal treatment of the technical solution of the present application were randomly selected. The size of the single-layer substrate obtained after sintering the green ceramic sheets was all 12cm×12cm, and the test was performed under a 6000K white light LED lamp. Point defects caused by slag such as apparent porcelain buds and pits of single-layer substrates, and the proportion of defective single-layer substrates in 200 single-layer substrates was counted. The green ceramic sheets produced in the same batch were laminated and sintered to obtain a laminated substrate (2 green ceramic sheets laminated), 200 laminated substrates were randomly selected, and the slag shadow inside the laminated substrate was inspected under a 6000K white LED lamp. , and count the proportion of the 200 laminated substrates with slag shadows.

The comparative experimental results are shown in Table 1.

Proportion of defective single-layer substrates Proportion of laminated substrates with slag shadows Comparative Example 1 37.5% 23.5% Comparative Example 2 31.0% 19.0% Comparative Example 3 6.5% 3.5%

It can be seen from the above experimental results that in Comparative Example 2, only the method of blowing the green ceramic sheets with high pressure gas cannot achieve the expected effect of dust removal and slag removal, and it may be because the high pressure gas blows the slag and dust around the discharge end of the casting machine. After rising, it falls on the green ceramic sheet, causing secondary pollution of the green ceramic sheet, resulting in a high proportion of defective single-layer substrates and a high proportion of laminated substrates with slag shadows. In Comparative Example 3, the proportion of defective single-layer substrates obtained after dust removal and slag removal by the technical solution of the present application was significantly lower than that of Comparative Examples 1 and 2, and the proportion of laminated substrates with slag shadows was significantly reduced. The ratio is obviously reduced, so the technical solution of the present application is excellent in the dust removal and slag removal effect on the green ceramic sheets, and the expected effect can be achieved.

Please refer to FIG. 1 to FIG. 5 , an embodiment of the present application discloses a device for cleaning slag with a green ceramic tape. The device for cleaning slag with a green ceramic tape is installed on the casting machine 100 to remove the slag on the green ceramic tape. The belt is a green ceramic belt cut by the casting machine 100, that is to say, a slag cleaning device can be installed on the casting machine 100 to remove the slag from the cut green ceramic belt. The slag cleaning device disclosed in the present application includes a support frame 200, a cold air device 300, a static elimination strip 400, a suction device 500 and a high-pressure air blowing device 600, wherein:

The support frame 200 is erected on the casting machine 100, can be connected to the frame of the casting machine 100 by bolts, and spans the green ceramic belt on the casting machine 100, and the moving direction of the green ceramic belt on the casting machine 100 In the first direction, the cold air device 300, the static elimination strip 400, the suction device 500 and the high-pressure air blowing device 600 are sequentially arranged on the support frame 200, that is to say, the green ceramic tape first passes through the cold air device 300, After passing through the static elimination strip 400, then through the suction device 500 and the high-pressure air blowing device 600, the air outlet of the cold air device 300 is arranged opposite to the green ceramic belt, so that the cold air blown by the cold air device 300 faces the green ceramic belt. It can maximize the cooling effect of cold air. The suction device 500 and the high-pressure air blowing device 600 are located on the same side of the green ceramic tape, the suction direction of the suction device 500 is the second direction, and the blowing direction of the high-pressure air blowing device 600 is the third direction.

Please refer to FIG. 5 again, the angle between the vectors of the first direction and the third direction is 100° to 160°, that is, the angle between the blowing direction of the high-pressure air blowing device 600 and the moving direction of the green ceramic tape is 100° To 160°, in this case, the high-pressure gas has a good blowing effect on the slag, so that more slag can be blown up from the green ceramic belt. To avoid that when the vector angle between the first direction and the third direction is large, the high-pressure gas flicks over the surface of the green ceramic belt, and the slag on the green ceramic belt cannot be blown up, causing the slag to continue to adhere to the green ceramic belt. Belt, to prevent the slag removal effect is not good, at the same time, high-pressure gas flicking over the surface of the green ceramic belt will cause inconvenient suction. Or avoid that when the vector angle between the first direction and the third direction is small, the high-pressure gas is blowing against the green ceramic belt, which will cause a greater impact on the green ceramic belt, so as to avoid the high-pressure gas blowing damage to the green ceramic belt, resulting in The ceramic belt is broken or damaged. At the same time, when the high-pressure gas is blowing against the green ceramic belt, the high-pressure gas escapes around, which is not convenient for suction, causing the slag to float away from the surrounding area and cannot be removed.

The vector angle between the second direction and the third direction is 120° to 170°, that is, the angle between the suction direction of the suction device 500 and the moving direction of the green ceramic tape is 120° to 170°. In this case The suction device 500 has a good suction effect on the high-pressure gas blown by the high-pressure air blowing device 600, and the high-pressure gas carrying the slag is sucked away, so as to prevent the slag from falling everywhere, and prevent the slag from continuing to fall on the green porcelain. Therefore, the secondary pollution of the green ceramic belt is avoided, and the cleaning effect of the green ceramic belt material slag cleaning device is improved. To avoid that when the vector angle between the second direction and the third direction is large, the gas in the upper part of the suction port of the suction device 500 cannot be sucked, so that the slag floats on the upper part, and cannot be sucked and flicked over the surface of the green ceramic tape. The high-pressure gas caused by the inability to suck away the slag that has been flicked on the surface of the green ceramic belt, resulting in poor removal effect. Or avoid that when the vector angle between the second direction and the third direction is small, the suction port of the suction device 500 sucks against the green ceramic belt, so that the high-pressure gas cannot be suctioned comprehensively, and the high-pressure gas may be sucked from the suction port. One side floats to the upper part, causing the slag to float on the upper part, resulting in poor removal effect.

It should be noted that the above-mentioned vector angle value between the first direction and the third direction and the vector angle value between the second direction and the third direction are obtained by the inventor of the present application through multiple calculations, software simulation analysis, and experimental practice. .

In the apparatus for cleaning the slag of the green ceramic tape disclosed in the embodiment of the present application, the green ceramic tape is first cooled by the cold air device 300, and when the green ceramic tape is cooled to the first temperature, the cooled slag and the cooled green ceramic tape are removed. The viscosity between the belts decreases, the slag falls off the green ceramic belt, and then the green ceramic belt is destaticized by the static elimination strip 400 to eliminate the electrostatic adsorption force between the material slag and the green ceramic belt, so as to further reduce the material slag The degree of adhesion between the green ceramic belt and the green ceramic belt, so that the slag can fall off the green ceramic belt more easily. Finally, the high-pressure air blowing device 600 is used to blow back the slag on the green ceramic belt. The high-pressure gas of the green ceramic belt takes away the slag on the green ceramic belt, thereby removing the material slag on the green ceramic belt. The slag floats everywhere to prevent the slag from continuing to fall on the green ceramic belt, thereby avoiding secondary pollution of the green ceramic belt, and the method of backflushing can prevent the high-pressure gas from blowing the material slag to the green ceramic belt that has been removed. , so as to avoid secondary pollution of the green ceramic tape.

It can be seen that the cleaning effect of the above-mentioned green ceramic slag cleaning device is excellent. Compared with the purging mechanism in the prior art, the green ceramic slag cleaning device disclosed in the present application can remove the material that is relatively firmly adhered to the green ceramic belt. The slag can not only eliminate the slag scattered on the surface of the green ceramic belt, but also eliminate the slag adhered to the green ceramic belt, and prevent the slag from continuing to be blown up by avoiding the surrounding slag and dust during cleaning. It falls on the green ceramic belt, thereby causing secondary pollution of the green ceramic belt, thereby preventing the slag and dust from affecting the quality of the green ceramic belt, improving the quality of the green ceramic belt, and further improving the yield of the green ceramic belt.

In order to further prevent the slag blown up by the high-pressure gas from falling everywhere, and then continue to fall on the green ceramic belt, causing secondary pollution of the green ceramic belt, optionally, the green ceramic belt material and slag cleaning device may also include a dust-proof device. The cover 700, the suction device 500 and the high-pressure air blowing device 600 are all located in the dust cover 700, so as to collect the high-pressure gas blown out by the high-pressure air blowing device 600 in the dust cover 700, and prevent the high-pressure gas carrying the slag from drifting to other At the same time, the suction device 500 only needs to suck the high-pressure gas in the dust cover 700, so that the high-pressure gas carrying the slag can be sucked away to a large extent, so that the slag can be removed completely without residue. secondary pollution, thereby improving the slag removal effect of the green ceramic belt slag cleaning device, avoiding the slag and dust affecting the quality of the green ceramic belt, improving the quality of the green ceramic belt, and further improving the yield of the green ceramic belt.

Further, the distance between the opening of the dust cover 700 and the green ceramic tape is the first distance, and the first distance is 2 cm to 10 cm, so that the distance between the opening of the dust cover 700 and the green ceramic tape is set smaller, It will not affect the normal movement of the green ceramic belt. When the distance between the opening of the dust cover 700 and the green ceramic belt is small, it can further prevent the high-pressure gas carrying slag from passing through the opening of the dust cover 700 and the green ceramic belt. The gaps between them are scattered to other positions, and the high-pressure gas is kept in the dust cover 700 to a large extent, so that the slag is kept in the dust cover 700, and then sucked away by the suction device 500, which further improves the removal Effect.

Preferably, the temperature of the cold air blown out by the cold air device 300 is 5°C to 15°C, and the cold air at this temperature can cool the green ceramic belt to 5°C to 20°C. The viscosity between them is low, and the predetermined characteristics of the green ceramic belt are not damaged, so that the viscosity between the slag and the green ceramic belt is not reduced due to insufficient cooling, or the predetermined characteristics of the green ceramic belt are prevented from being damaged due to excessive cooling.

Preferably, the pressure of the high-pressure gas blown by the high-pressure air blowing device 600 can be 0.3Mpa to 1.5Mpa. Within this pressure range, the high-pressure gas can blow up the slag on the green ceramic belt, and then be taken away by suction , to prevent the slag on the green ceramic belt from being able to be blown up due to the low air pressure, which will cause the slag to continue to adhere to the green ceramic belt and prevent the slag removal effect from being poor. Or avoid blowing away the slag due to high air pressure. Part of the high-pressure gas escapes and is not taken away by suction, causing the slag to fall everywhere, and then continue to fall on the green ceramic belt, causing secondary pollution of the green ceramic belt. At the same time, avoid high air pressure and damage the green ceramic tape, resulting in rupture or damage of the green ceramic tape.

Preferably, the distance between the air blowing port of the high-pressure air blowing device 600 and the suction port of the suction device 500 can be 10 cm to 20 cm, so that the high-pressure gas blown by the high-pressure air blowing device 600 blows through the green ceramic tape for the first time after the It is sucked and taken away by the suction device 500 to prevent the high-pressure gas from blowing to other places, and to prevent the slag from falling to other places with the high-pressure gas, so that the high-pressure gas blows through the slag carried by the green ceramic belt for the first time. It is sucked and taken away by the suction device 500 to further improve the removal effect.

The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity, all possible combinations of the technical features in the above-described embodiments are not described. However, as long as there is no contradiction between the combinations of these technical features, All should be regarded as the scope described in this specification.
