[0014] A method for using an apparatus for preparing packaging products from modified salt gypsum, comprising the following specific steps: S1 pours modified salt gypsum powder into the device through the feed pipe, and at the same time, pours fibrous material into the opening box. Under the action of the opening mechanism, the fiber material is opened to form finer and looser fiber bundles that enter the interior of the outer shell and enter the interior of the crushing box along with the modified salt gypsum powder. S3 modified salt gypsum and fiber bundles are shredded inside the shredding box by a shredding mechanism, allowing them to be fully mixed in a smaller volume. The mixture then enters the feeding pipe and is quantitatively delivered to the mixing tank.

[0016] 2. The method for preparing packaging products with modified salt gypsum includes a cleaning mechanism consisting of an air pump, a connecting pipe, and an air outlet. When the mixture is being crushed or the device is not in operation, the air pump can be started simultaneously. Air is drawn from the outside through the second through hole and the connecting pipe, and the airflow is sprayed at high speed through the air outlet onto the inner wall of the inner liner to clean it and remove the attached material.
[0017] 3. The method for preparing packaging products with modified salt gypsum involves setting an inner liner inside the crushing box. By rotating the inner liner, the first through hole aligns with the connection port of the first water pipe and the crushing box, allowing clean water to be introduced from inside the water tank for internal cleaning.

Therefore, they should not be construed as limitations on this invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Example
[0022] like Figures 1 to 7As shown, this embodiment describes a method for preparing packaging products using modified gypsum, including an outer shell 1. The upper surface of the outer shell 1 is connected to a feed pipe 2 and a discharge port 3 at its left and right ends, respectively. The top of the discharge port 3 is connected to an opening box 4. Modified gypsum powder is fed into the device through the feed pipe 2, while fibrous material is placed inside the opening box 4 for opening and then enters the device through the discharge port 3. An opening mechanism 5 is installed inside the opening box 4, and a first motor box 6 is provided on the rear surface of the opening box 4. The opening mechanism 5 can open the fibrous material, making it into finer and looser fiber bundles, which is convenient for subsequent crushing, mixing and stirring. A fixing rod 7 is connected to the left end surface of the outer shell 1, and a crushing box 8 is connected to the other end of the fixing rod 7. The top of the crushing box 8 is connected to the lower surface of the outer shell 1. The fixing rod 7 fixes the crushing box 8 in place. An inner liner 9 is movably connected inside the crushing box 8. A notch is opened on the front end surface of the inner liner 9. A first through hole 10 is opened in the middle of the upper and lower surfaces of the crushing box 8 and the inner liner 9. A second through hole 11 is opened at both ends of the upper surface of the crushing box 8 and the inner liner 9. In the initial state, the two first through holes 10 are in corresponding positions, so that the mixture can enter the inner liner 9 from the inside of the outer shell 1 for crushing. At the same time, the two second through holes 11 are also in corresponding positions, so that air can be drawn from the outside for internal cleaning. A second motor box 13 is installed on the front end surface of the crushing box 8 and the rear end surface of the inner liner 9. A connecting rod 12 is connected to both ends of the rear end surface of the inner liner 9. The connecting rod 12 facilitates manual rotation of the inner liner 9. A cleaning mechanism 15 is provided in the middle of the inner liner 9, and a crushing mechanism 14 is provided on the outside of the cleaning mechanism 15. The crushing mechanism 14 can fully crush and mix the mixture. The cleaning mechanism 15 can use airflow to flush the inner wall of the inner liner 9 while crushing, thereby preventing material from adhering. A water tank 16 is provided on the right side of the crushing box 8, and a mixing box 18 is provided below the water tank 16. A stirring rod 24 is installed inside the mixing box 18. The crushed and mixed material finally enters the mixing box 18, and water is provided by the water tank 16 in a metered manner to stir it into a slurry.
[0023] Furthermore, the lower surface of the outer shell 1 has an inclined structure, and the right end of the lower surface of the outer shell 1 is connected to the water tank 16 through a support rod. The inclined lower surface allows the fiber bundle to slide automatically and fall into the interior of the crushing box 8 together with the modified salt gypsum powder.
[0024] Furthermore, the opening mechanism 5 includes a first roller 501, a second roller 502, protrusions 503, and a connecting shaft 504. The first roller 501 and the second roller 502 are located on the left and right sides inside the opening box 4, respectively. The outer surfaces of the first roller 501 and the second roller 502 are evenly distributed with protrusions 503, and the front and rear end surfaces of the first roller 501 and the second roller 502 are connected to the connecting shaft 504. The first roller 501 and the second roller 502 are driven to rotate by two motors inside the first motor box 6. When the fiber material falls between the first roller 501 and the second roller 502, it will be combed by the protrusions 503 on the surface, thereby breaking down the tight and entangled fiber clumps into a fine and fluffy state, which is convenient for subsequent mixing.
[0025] Furthermore, the rear end of the inner liner 9 extends through the outside of the grinding box 8, which facilitates manual control of the rotation of the inner liner 9. To maintain stability between the inner liner 9 and the grinding box 8, a rubber pad can be added between them to increase friction, or the inner liner 9 can be fixed with screws after rotation is complete.
[0026] Furthermore, the crushing mechanism 14 includes a first connecting block 1401, a second connecting block 1402, and blades 1403. The first connecting block 1401 and the second connecting block 1402 are located on the front and rear sides of the inner liner 9, respectively. Multiple blades 1403 are connected at equal angles on the outer surfaces of the first connecting block 1401 and the second connecting block 1402. By controlling the rotation of the first connecting block 1401 and the second connecting block 1402 through the two second motor boxes 13 on the surface of the crushing box 8 and the inner liner 9, the blades 1403 can rotate at high speed to crush and mix the mixture.
[0027] Furthermore, the first connecting block 1401 and the second connecting block 1402 are respectively connected to the front surface of the crushing box 8 and the rear surface of the inner liner 9, and the first connecting block 1401 and the second connecting block 1402 rotate in opposite directions. By rotating in opposite directions, the mixture can be fully crushed.
[0028] Furthermore, the cleaning mechanism 15 includes an air pump 1501, connecting pipes 1502, and an air outlet 1503. The air pump 1501 is located between the first connecting block 1401 and the second connecting block 1402, and its front and rear ends are movably connected to the first connecting block 1401 and the second connecting block 1402, respectively. Two connecting pipes 1502 are symmetrically connected to the outer surface of the air pump 1501, and the other ends of the two connecting pipes 1502 correspond to the positions of the two second through holes 11, respectively. The air outlet 1503 is located at the first connecting block 1401. Both the outer surfaces of block 1401 and the second connecting block 1402 are provided with openings. When the mixture is being crushed or the device is not in operation, the air pump 1501 can be started simultaneously. Air is drawn from the outside through the second through hole 11 and the connecting pipe 1502, and the airflow is sprayed out at high speed through the air outlet 1503 to clean the inner wall of the inner liner 9 and remove the attached material. The connection between the first connecting block 1401, the second connecting block 1402 and the air pump 1501 is sealed to ensure that there are no gaps and that the rotation is not affected.
[0029] Furthermore, the left and right ends of the outer shell 1 are respectively connected to a first water pipe 19 and a second water pipe 20 via a water pump. The other ends of the first water pipe 19 and the second water pipe 20 are respectively connected to the crushing box 8 and the water tank 16. A support plate 17 is provided between the water tank 16 and the mixing box 18. The water inside the water tank 16 can be supplied not only to the inside of the mixing box 18, but also to the inside of the crushing box 8. It is only necessary to control the inner liner 9 to rotate so that the first through hole 10 is connected to the crushing box 8 and the first water pipe 19.
[0030] Furthermore, a feeding pipe 21 is connected to the left end surface of the mixing tank 18, and the upper left end of the feeding pipe 21 is connected to the crushing box 8. A support leg 22 is connected to the lower surface of the feeding pipe 21, and a screw rod 23 is installed inside the feeding pipe 21. The screw rod 23 is rotated by a motor installed at the left end of the feeding pipe 21, so that the mixture is quantitatively fed into the interior of the mixing tank 18.
[0031] A method for using an apparatus for preparing packaging products from modified salt gypsum, comprising the following specific steps: S1 pours modified salt gypsum powder into the device through the feed pipe 2, and at the same time, pours fiber material into the opening box 4. Under the action of the opening mechanism 5, the fiber material is opened to form finer and looser fiber bundles that enter the interior of the outer shell 1 and enter the interior of the crushing box 8 along with the modified salt gypsum powder. S3 modified salt gypsum and fiber bundles are shredded inside the shredding box 8 by the shredding mechanism 14, so that the two can be fully mixed in a smaller volume. Then the mixture enters the feeding pipe 21 and is quantitatively transported to the mixing tank 18 through the feeding pipe 21. At this time, water from the water tank 16 is pumped into the mixing tank 18 by a water pump, and the mixture is stirred by the stirring rod 24 to obtain a slurry. Finally, the slurry is taken out through the outlet on the rear surface of the mixing tank 18 for mold shaping. When the crushing mechanism 14 is cutting the mixture, the cleaning mechanism 15 can draw air from the outside and make the airflow spray out at high speed inside the inner liner 9 to flush the inner wall, so as to avoid the mixture from adhering. When cleaning the inside of the inner liner 9, the connecting rod 12 is manually pushed to make the inner liner 9 rotate inside the crushing box 8, and the first through hole 10 on the upper surface of the inner liner 9 is aligned with the connection port between the first water pipe 19 and the crushing box 8. Then, clean water can be introduced and the crushing mechanism 14 can be started simultaneously to perform internal cleaning.
