DETAILED DESCRIPTION

[0041] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0042] like Figures 1 to 8 As shown, a gypsum board raw material mixing device according to an embodiment of the present invention comprises a stirring tank 1, a stirring motor 11 is installed at the top of the stirring tank 1, a stirring paddle 111 is arranged inside the stirring tank 1, the end of the rotating shaft of the stirring motor 11 is fixedly connected to the top of the stirring paddle 111, a feeding port 12 is arranged on one side of the top of the stirring tank 1, a vibration pump 13 is installed on the side of the stirring tank 1 away from the feeding port 12, a discharge hopper 2 is arranged above the feeding port 12, a processing box 21 is fixed at the bottom end of the discharge hopper 2, a screening bucket 25 is arranged on one side of the processing box 21, and two crushing rollers 22 are rotatably connected to the other side of the processing box 21. The processing box 21 is tilted and arranged inside, and the bottom end of the inclined surface of the screen bucket 25 faces the crushing roller 22. A plurality of protrusions are fixed to the outside of the crushing roller 22. A transmission gear 221 is fixed to one end of the crushing roller 22. The two transmission gears 221 are meshed and connected. A pulley is fixed to the end of one of the crushing rollers 22 away from the transmission gear 221. A first motor 224 is installed at the bottom end of the processing box 21. A pulley is also fixed to the end of the rotating shaft of the first motor 224. The pulley of the crushing roller 22 and the pulley of the first motor 224 are connected by a belt. A guide pipe 26 is fixed to the bottom end of the processing box 21. The bottom end of the guide pipe 26 is connected to the feed port 12.

[0043] When producing gypsum board, it is necessary to mix the raw materials to form slurry, and the slurry is used for subsequent molding. During the mixing process, gypsum powder is first put into the discharge hopper 2. At this time, the gypsum powder will fall into the screen bucket 25 through the guidance of the discharge hopper 2. The screen bucket 25 can screen the gypsum powder. The agglomerated gypsum powder blocks in the gypsum powder will fall to the position of the crushing roller 22 along the slope of the surface of the screen bucket 25. At this time, the first motor 224 is started to drive the crushing roller 22 to rotate through the belt and the pulley. The two crushing rollers 22 rotate in opposite directions. At this time, the fallen gypsum powder blocks will be crushed and broken by the crushing roller 22, and the crushed gypsum powder blocks will become gypsum powder and mix with the unagglomerated gypsum powder. The gypsum powder is mixed together, and then the gypsum powder is input into the feed port 12 through the material guide pipe 26 to prevent the agglomerated gypsum powder from affecting the subsequent mixing. The gypsum powder is output to the inside of the mixing tank 1 through the feed port 12, and then additives and water are added to the inside of the mixing tank 1. The stirring motor 11 is started to drive the stirring paddle 111 to rotate. At this time, the stirring paddle 111 can mix the raw materials in the mixing tank 1. After mixing into a slurry, the vibration pump 13 is started to vibrate the slurry in the mixing tank 1. The vibration of the vibration pump 13 can generate small bubbles in the slurry, which can enhance the sound insulation effect of the gypsum board. The mixed slurry is then output from the inside of the mixing tank 1.

[0044] like Figures 2 to 5 As shown, two movable plates 252 are fixed on each side of the screen bucket 25, and movable grooves 211 matching the movable plates 252 are opened on both sides of the processing box 21. The movable plates 252 are slidably connected inside the movable grooves 211, and a guide rod 212 is fixed inside the movable grooves 211. The guide rod 212 runs through the inside of the movable plates 252, and a first spring 213 is sleeved on the outside of the guide rod 212. One end of the first spring 213 is fixedly connected to the inner wall of the movable groove 211, and the other end of the first spring 213 is fixedly connected to the movable plate 252. An extension rod is fixed to the bottom end of the movable plate 252 close to the transmission gear 221, and a plurality of push posts 222 are fixed at equal intervals on the end of the transmission gear 221 close to the movable plate 252 away from the crushing roller 22;

[0045] When the crushing roller 22 rotates, the two transmission gears 221 will be driven to rotate at the same time. At this time, the transmission gear 221 drives the push column 222 to rotate. During the rotation of the push column 222, it will contact the extension rod of the movable plate 252, and the extension rod is pushed by the push column 222. At this time, the extension rod drives the movable plate 252 to move inside the movable groove 211. At this time, the movable plate 252 squeezes the first spring 213. When the push column 222 rotates to a certain distance, it will separate from the extension rod. The distance between the bottom end of the extension rod of the movable plate 252 and the center of the transmission gear 221 is less than the distance between the bottom end of the push column 222 and the center of the transmission gear 221, so that the push column 222 can be separated from the extension rod. At this time, the first spring 213 will push the movable plate 252 to reset inside the movable groove 211. Continuous operation in the above-mentioned motion state will cause the screen bucket 25 to move back and forth. At this time, vibration will be generated, making it easier for the screen bucket 25 to screen the gypsum powder on the surface to prevent the gypsum powder from accumulating inside the screen bucket 25.

[0046] like Figures 4 to 7 As shown, one side of the bottom end of the sieve bucket 25 is rotatably connected with a threaded rod 255 through a support block, one end of the threaded rod 255 is provided with a second motor 253, the second motor 253 is installed at the bottom end of the sieve bucket 25, the end of the rotating shaft of the second motor 253 is fixedly connected to one end of the threaded rod 255, the external thread of the threaded rod 255 is connected with a moving block 254, a sliding rod is fixed on the side of the bottom end of the sieve bucket 25 symmetrical to the threaded rod 255, the outside of the sliding rod is slidably connected with a slider, a moving rod 256 is fixed between the moving block 254 and the slider, a plurality of telescopic holes 2561 are evenly spaced at the top of the moving rod 256, a second spring 2571 is fixed at the bottom end of the telescopic hole 2561, a push block 257 is fixed at the top of the second spring 2571, a conical slope is provided above the push block 257, and a plurality of sieving holes 251 are evenly spaced at the bottom end of the sieve bucket 25;

[0047] After the sieve bucket 25 is used, gypsum powder is easily accumulated inside the sieve hole 251. At this time, the inside of the sieve hole 251 needs to be cleaned, and the second motor 253 is started to drive the threaded rod 255 to rotate, and the threaded rod 255 drives the moving block 254 to move, and the moving block 254 drives the moving rod 256 to move. At this time, the push block 257 is retracted into the inside of the telescopic hole 2561, and when the moving rod 256 moves to the position of the sieve hole 251, the second spring 2571 can push the push block 257 to extend from the inside of the telescopic hole 2561, and the push block 257 can clear the inside of the sieve hole 251, and then the moving rod 256 will be driven to continue to move, and under the guidance of the conical slope above the push block 257, the edge of the sieve hole 251 can push the push block 257 into the inside of the telescopic hole 2561, and this can be repeated so that the push block 257 can clean the inside of each sieve hole 251.

[0048] like Figure 7As shown, a brush 2572 is fixed to the top of the push block 257;

[0049] When the push block 257 extends into the screen hole 251, the brush 2572 will enter the screen hole 251 along with the push block 257. At this time, the brush 2572 can sweep the gypsum powder inside the screen hole 251 to make the inside of the screen hole 251 cleaner. There is a certain gap between the bristles of the brush 2572 to prevent the push block 257 from being affected by the bristles during the extension and retraction process.

[0050] like Figures 1 to 8 As shown, a rotating disk 223 is fixed to one end of the crushing roller 22 away from the first motor 224 and away from the transmission gear 221, a pressing roller 23 is arranged above the two crushing rollers 22, a lifting frame 231 is fixed to the top of the pressing roller 23, the lifting frame 231 penetrates the top of the processing box 21, and a connecting arm 232 is rotatably connected to one end of the lifting frame 231 close to the rotating disk 223, and the bottom end of the connecting arm 232 is rotatably connected to the rotating disk 223;

[0051] During the process of the crushing roller 22 crushing the gypsum powder blocks, some of the gypsum powder blocks may be large, and it is difficult for the crushing roller 22 to crush them at this time. Therefore, it is necessary to apply a thrust to the top of the gypsum powder blocks to assist the crushing roller 22. During the rotation of the crushing roller 22, the turntable 223 is driven to rotate. At this time, the turntable 223 drives the connecting arm 232 to move. During the movement of the connecting arm 232, the lifting frame 231 is driven to move up and down. At this time, the lifting frame 231 drives the pressure roller 23 to move up and down inside the processing box 21. During the downward movement of the pressure roller 23, the gypsum powder blocks between the two crushing rollers 22 are pressed downward, which makes it easier for the crushing roller 22 to crush the gypsum powder blocks.

[0052] like Figures 1 to 3 As shown, a material spraying pipe 24 is provided below the sieve bucket 25, and the material spraying pipe 24 is fixedly connected to the processing box 21, a blower 241 is installed at one end of the material spraying pipe 24, and a material storage box 242 is provided above one end of the material spraying pipe 24 close to the blower 241, and the material storage box 242 is fixedly connected to the processing box 21, and the bottom end of the material storage box 242 is connected to the material spraying pipe 24 through a pipeline;

[0053] During mixing, the gypsum powder and the foaming agent need to be stirred, but the foaming agent is usually placed directly into the mixing tank 1, which will cause the gypsum powder to be stirred for a longer time inside the mixing tank 1. Therefore, during the discharge process, the foaming agent is placed into the storage box 242. At this time, the blower 241 is started to blow air into the spray pipe 24. A negative pressure is generated at the connection between the spray pipe 24 and the storage box 242, which can suck the foaming agent inside the storage box 242 into the spray pipe 24. At the same time, the airflow blown by the blower 241 is sprayed into the processing box 21. At this time, the foaming agent can be mixed with the gypsum powder in advance to reduce the time for subsequent stirring.

[0054] like Figures 1 to 10 As shown, the top of the guide tube 26 is rotatably connected with a spiral blade 261, the bottom of the guide tube 26 is installed with a third motor 262, the end of the rotating shaft of the third motor 262 is fixedly connected with the spiral blade 261, the top of the spiral blade 261 is fixed with a toothed disc 263, one side of the top of the toothed disc 263 is provided with a rotating rod 265, the rotating rod 265 is rotatably connected with the guide tube 26, the end of the rotating rod 265 close to the toothed disc 263 is fixed with a linkage gear 264, the linkage gear 264 is meshed with the toothed disc 263, and the outer side of the rotating rod 265 is fixed with a flip plate 266;

[0055] After the foaming agent is blown into the interior of the gypsum powder, only a preliminary mixing is performed therebetween. At this time, the third motor 262 is started to drive the spiral blade 261 to transport the falling mixture. During the transportation process, the toothed disc 263 drives the linkage gear 264 to rotate. At this time, the linkage gear 264 drives the rotating rod 265 to rotate. The rotating rod 265 drives the flip plate 266 to stir and mix the mixture transported by the surface of the spiral blade 261 again, so that the mixing can be more sufficient. Then, the mixture can be transported to the bottom of the guide pipe 26 under the transportation of the spiral blade 261, and then transported to the inside of the mixing tank 1 through the feed port 12.

[0056] like Figures 1 to 10 As shown, the retractable plate 267 is movably connected inside the flip plate 266, and a third spring 268 is fixed between the retractable plate 267 and the inner side of the flip plate 266;

[0057] During the rotation of the flip plate 266, the contact distance between the flip plate 266 and the spiral blade 261 will change. In order to prevent the flip plate 266 from interfering with the rotation of the spiral blade 261, a telescopic plate 267 is set inside the flip plate 266. The third spring 268 pushes the telescopic plate 267 out so that the telescopic plate 267 can contact the mixture. When the distance between the flip plate 266 and the spiral blade 261 changes, the telescopic plate 267 will automatically telescope inside the flip plate 266 due to external force, which is more convenient for mixing.

[0059] S1. Select gypsum powder, foaming agent and additives with reliable quality according to production requirements;

[0060] S2, pre-treating the gypsum powder, separating and crushing the internal lumps;

[0061] S3, adding gypsum powder, water and liquid additives into the mixing tank 1 for preliminary stirring and mixing to form a uniform slurry;

[0062] S4, using the vibration pump 13 to vibrate the slurry inside the stirring tank 1, so that small bubbles are generated in the slurry inside the stirring tank 1;

[0063] S5. Output the mixed slurry to the outside.
