[0037] Specific usage method and function of this embodiment: In the present invention, by starting the third motor 302 to drive the rotation of the third lead screw 303, the cover body 304 is driven to move to the outside of the inner cylinder 301. The air cylinder 305 is started to drive the scraper 306 to move to the bottom inner side position of the inner cylinder 301 to realize the sealing effect on the inner cylinder 301. Waste paper and other materials after cleaning are added into the inner cylinder 301, and the corresponding amount of white water is added. When the crushing roller 408 faces downward, the fourth motor 403 is directly started to drive the rotation of the screw 402, thereby driving the connecting plate 401 and the connecting rod 4 to move downward along the outside of the cylinder body 3, so that the crushing roller 408 enters the inner cylinder 301, and the fixing plate 404 is attached to the top of the inner cylinder 301. Then, the bottom group of sixth motors 406 is started to drive the crushing roller 408 to rotate to crush the waste paper in the inner cylinder 301. After crushing, the fourth motor 403 drives the screw 402 to reverse, so that the fixing plate 404 rises. Then, the fifth motor 405 is started to drive the fixing plate 404 to flip between the two connecting plates 401, so that the grinding roller 407 faces downward. Then, the grinding roller 407 enters the inner cylinder 301 for grinding to complete the grinding process. After grinding is completed, the third motor 302 is started to drive the rotation of the third lead screw 303, so that the cover body 304 slides downward along the outside of the inner cylinder 301. The cover body 304 stops after sliding to the inside of the transmission ring 501, and the four rectangular grooves on the outside of the cover body 304 are engaged with the four rectangular protrusion structures on the inside of the transmission ring 501. At this time, the inner cylinder 301 loses the sealing effect provided by the cover body 304, and the pulp water inside it can fall into the lower box body 2 through the sieve holes on the outside of the inner cylinder 301. In order to accelerate the filtration of the inner cylinder 301, the transmission wheel 201 can be started to drive the transmission ring 501 to rotate. The transmission ring 501 drives the cover body 304 to rotate. Through the cooperation of the rectangular grooves on both sides of the cover body 304 and the rectangular protrusions on both sides of the outer wall of the inner cylinder 301, the cover body 304 can drive the inner cylinder 301, so that the inner cylinder 301 rotates inside the cylinder body 3 along with the cover body 304. At the same time, through the cooperation of the rectangular protrusions on both sides of the inner wall of the inner cylinder 301 and the scraper 306, the scraper 306 and the air cylinder 305 can be driven to rotate synchronously. During the high-speed rotation of the inner cylinder 301, centrifugal force is generated on the pulp water inside the inner cylinder 301, thereby accelerating the screening of the pulp water. Only the pulp water that can pass through the sieve holes on the outer wall of the inner cylinder 301 is qualified pulp water and enters the lower box body 2. If the inner cylinder 301 is blocked during the screening process, the air cylinder 305 can be started to drive the scraper 306 to move upward along the inner wall of the inner cylinder 301 by a certain distance to clean the pulp water blocked on the sieve holes to a certain extent and complete the screening process. After screening is completed, the residual pulp water inside the inner cylinder 301 can be scraped to the top of the inner cylinder 301 by starting the air cylinder 305 to drive the scraper 306 upward, which is convenient for subsequent cleaning and recycling.Greatly improves the cleaning efficiency; after the pulp and water enter the box body 2, a certain amount of ingredients are added and stirred. If foam appears during the stirring process, the second motor 205 can be started to drive the second lead screw 206 to rotate, thereby driving the second slider 204 to move along the two groups of second guide rails 203. At the same time, the buoyancy plate 208 is driven to move through the first slide bar 207. Under the action of the buoyancy of the pulp and water, the buoyancy plate 208 can always maintain its position on the surface of the pulp and water. At the same time, the pump body 202 is started to generate suction at the suction port 209 through the pipeline, so as to extract the foam floating on the surface of the pulp and water and discharge it through the pipeline, which can effectively remove the foam on the surface of the pulp and water, thereby facilitating the subsequent production process and being beneficial to improving the quality of papermaking; then the first motor 104 is started to drive the first lead screw 105 to rotate, thereby driving the first slider 103 and the box body 2 to rotate along the first guide rail 102, and the pulp and water are evenly sprayed on the long net part 101 through the flow pulp port 210 at the bottom of the box body 2, and the subsequent processing and forming process is carried out through the forming part 1 to complete the entire papermaking process; by integrating steps such as crushing, pulping, screening, and pulp blending, there is no need to use a variety of different equipment for production. This device greatly reduces the occupied space and area of the equipment, is more convenient for transportation and use, and at the same time reduces the procurement and use costs of the equipment, reduces production costs, is convenient for small production sites to use, and effectively shortens the papermaking process.,

10. A short - process papermaking process, which adopts the short - process papermaking device according to claim 9, characterized in that: Including the following steps: Step 1: Start the third motor (302) to drive the third lead screw (303) to rotate, thereby driving the cover body (304) to move to the outside of the inner cylinder (301). Start the cylinder (305) to drive the scraper (306) to move to the inner bottom position of the inner cylinder (301) to achieve the sealing effect on the inner cylinder (301). Add the cleaned waste paper into the inner cylinder (301) and add the corresponding amount of white water. With the crushing roller (408) facing downwards, directly start the fourth motor (403) to drive the screw (402) to rotate, thereby driving the connecting plate (401) and the connecting rod (4) to move downward along the outside of the cylinder body (3), so that the crushing roller (408) enters the inner cylinder (301), and the fixing plate (404) fits against the top of the inner cylinder (301). Then start the bottom group of sixth motors (406) to drive the crushing roller (408) to rotate to crush the waste paper in the inner cylinder (301); Step 2: After the crushing is completed, drive the screw (402) to reverse by the fourth motor (403) to raise the fixing plate (404). Then start the fifth motor (405) to drive the fixing plate (404) to flip between the two connecting plates (401), so that the grinding roller (407) faces downwards. Then make the grinding roller (407) enter the inner cylinder (301) for grinding to complete the grinding process; Step 3: After the pulping is completed, start the third motor (302) to drive the third lead screw (303) to rotate, so that the cover body (304) slides downward along the outside of the inner cylinder (301). Stop after the cover body (304) slides to the inside of the transmission ring (501), and make the four rectangular grooves on the outside of the cover body (304) engage with the four rectangular protrusion structures on the inside of the transmission ring (501). At this time, the inner cylinder (301) loses the sealing effect provided by the cover body (304), and the pulp water inside it can fall into the lower box body (2) through the sieve holes on the outside of the inner cylinder (301). To accelerate the filtration of the inner cylinder (301), the transmission wheel (201) can be started to drive the transmission ring (501) to rotate, and the transmission ring (501) drives the cover body (304) to rotate. Through the cooperation of the rectangular grooves on both sides of the cover body (304) and the rectangular protrusions on both sides of the outer wall of the inner cylinder (301), the cover body (304) can drive the inner cylinder (301), so that the inner cylinder (301) rotates inside the cylinder body (3) along with the cover body (304). At the same time, through the cooperation of the rectangular protrusions on both sides of the inner wall of the inner cylinder (301) and the scraper (306), the scraper (306) and the cylinder (305) can be driven to rotate synchronously. During the high-speed rotation of the inner cylinder (301), centrifugal force is generated in the pulp water inside the inner cylinder (301), thereby accelerating the screening of the pulp water. Only the pulp water that can pass through the sieve holes on the outer wall of the inner cylinder (301) is qualified pulp water and enters the bottom box body (2). If the inner cylinder (301) is blocked during the screening process, the cylinder (305) can be started to drive the scraper (306) to move upward along the inner wall of the inner cylinder (301) by a certain distance to clean the pulp water blocked on the sieve holes to a certain extent and complete the screening process; Step 4: After the screening of the pulp is completed, the residual pulp water inside the inner cylinder (301) can be removed by starting the cylinder (305) to drive the scraper (306) upward, so as to scrape the pulp water inside the inner cylinder (301) to the top of the inner cylinder (301), which is convenient for subsequent cleaning and recycling, greatly improving the cleaning efficiency; after the pulp water enters the box body (2), a certain amount of ingredients are added for stirring. If foam appears during the stirring process, the second motor ((205)) can be started to drive the second lead screw (206) to rotate, thereby driving the second slider (204) to move along the two groups of second guide rails (203). At the same time, the buoyancy plate (208) is driven to move through the first slide rod (207). Under the action of the buoyancy of the pulp water, the buoyancy plate (208) can always maintain its position on the surface of the pulp water. At the same time, the pump body (202) is started to generate suction at the suction port (209) through the pipeline, so as to extract the foam floating on the surface of the pulp water and discharge it through the pipeline, which can effectively remove the foam on the surface of the pulp water, thus facilitating the subsequent production process and being beneficial to improving the quality of papermaking; then, by starting the first motor (104) to drive the first lead screw (105) to rotate, the first slider (103) and the box body (2) are driven to rotate along the first guide rail (102), and the pulp water is evenly sprayed out through the flow pulp port (210) at the bottom of the box body (2) onto the long wire section (101), and subsequent processing and forming operations are carried out through the forming section (1) to complete the entire papermaking process.
