All other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example 1: Please refer to Figure 1-Figure 4 The utility model provides a technical solution: a grinding device for chemical-mechanical pulp processing, comprising: a crushing box 1, a feed pipe 2 is fixedly provided on the top of the crushing box 1, a main shaft 3 is provided on the lower side of the feed pipe 2, and a secondary shaft 4 is installed on the upper and lower sides of the main shaft 3. A small crushing piece 5 is fixedly provided on the fixed sleeve of the main shaft 3, and a large crushing piece 6 is fixedly provided on the fixed sleeve of the secondary shaft 4. A grinding box 7 is provided on the lower side of the large crushing piece 6, and a knife-marked grinding ring 8 is fixedly connected to the inner ring surface of the grinding box 7. A knife-marked grinding block 9 is installed on the inner ring of the knife-marked grinding ring 8, and a discharge pipe 10 is provided on the lower side of the knife-marked grinding block 9.

[0023] The feeding pipe 2 can pour the material to be ground into the interior of the crushing box 1, and the main shaft 3 and the secondary shaft 4 rotate together, so that the main shaft 3 drives the small crushing pieces 5 to rotate, and the secondary shaft 4 drives the large crushing pieces 6 to rotate. During the rotation of the small crushing pieces 5 and the large crushing pieces 6, the raw materials inside the crushing box 1 can be crushed to avoid the occurrence of crushing dead corners inside the crushing box 1, thereby effectively crushing the materials. The crushed materials fall into the grinding box 7, and through the rotation of the knife-patterned grinding block 9, combined with the knife-patterned grinding ring 8, the crushed raw materials can be ground out. After the grinding is completed, the materials will flow to the bottom wall of the grinding box 7 through the gap between the knife-patterned grinding block 9 and the knife-patterned grinding ring 8, and then flow out along the discharge pipe 10, so as to facilitate the collection of the ground materials, thereby achieving the purpose of facilitating the crushing of the grinding device, avoiding the jamming of the raw materials due to the excessive volume of the raw materials during the grinding process, and ensuring the effect of raw material processing.

[0024] Embodiment 2: On the basis of embodiment 1, a sealing cover 11 is slidably inserted into the top of the feed pipe 2, the lower surface of the crushing box 1 is fixedly connected to the upper surface of the grinding box 7, and a driving motor 12 is fixedly installed on one side of the crushing box 1. The output end of the driving motor 12 passes through the crushing box 1 and is fixedly connected to one end of the main shaft 3. The other end of the main shaft 3 is rotatably sleeved on the side wall of the crushing box 1. A sealing cover 11 is slidably inserted into the top of the feed pipe 2. The sealing cover 11 can facilitate the sealing of the feed pipe 2 to prevent the material from flying out during the crushing process. The driving motor 12 is fixedly installed on the side wall of the crushing box 1, so that the driving motor 12 drives the main shaft 3 to rotate. The other end of the main shaft 3 is rotatably sleeved in the bearing seat fixedly installed on the side wall of the crushing box 1. Both ends of the secondary shaft 4 are rotatably sleeved on the side wall of the crushing box 1. A driving gear 13 is fixedly sleeved on one side of the main shaft 3, and a driven gear 14 is fixedly sleeved on one side of the countershaft 4. The driving gear 13 and the driven gear 14 are meshed and transmitted. Both ends of the countershaft 4 are also rotatably sleeved in the bearing seat fixedly installed on the side wall of the crushing box 1. The driving gear 13 is fixedly sleeved on one end of the main shaft 3, and the driven gear 14 is fixedly sleeved on one end of the countershaft 4. Cylinders 15 are fixedly installed on both sides of the bottom of the crushing box 1, and the output end of the cylinder 15 is fixedly connected to one side of the sealing partition 16. The sealing partition 16 is sleeved in the crushing box 1 and is slidably connected to the crushing box 1. The cylinders 15 fixedly installed on both sides of the bottom of the crushing box 1 are convenient for driving the sealing partition 16 to move. The sealing partition 16 slides on the inner side of the bottom of the crushing box 1, thereby separating the crushing box 1 from the grinding box 7.

[0025] The drive motor 12 is electrically connected to the external terminal control device. The sealing cover 11 is taken out and the material can be added to the crushing box 1 from the feed pipe 2. Then the sealing cover 11 is covered, so that the opening of the feed pipe 2 can be blocked by the sealing cover 11, thereby preventing the material from flying out during the crushing process and preventing the generation of dust. At this time, by starting the drive motor 12, the drive motor 12 drives the main shaft 3 fixedly connected to its output end to rotate. The main shaft 3 drives the small crushing pieces 5 arranged in a linear array thereon to rotate. At the same time, the main shaft 3 drives the driving gear 13 fixedly mounted on one end thereof to rotate. The driving gear 13 is meshed with the driven gears 14 on its upper and lower sides for transmission, so that the driven gear 14 drives the large crushing pieces 6 arranged in a linear array thereon to rotate. Therefore, during the rotation of the small crushing pieces 5 and the large crushing pieces 6, the raw materials can be effectively crushed. At the same time, the small crushing pieces 5 and the large crushing pieces 6 are staggered, thereby avoiding the occurrence of crushing dead corners in the crushing box 1, achieving the purpose of better crushing effect on the raw materials, and reducing the volume of the raw materials to improve the effect of subsequent raw material grinding.

[0026] Example 3: On the basis of Example 2, the discharge pipe 10 is fixedly sleeved at the bottom of the grinding box 7 and the discharge pipes 10 are arranged in a circular array. A high-torque motor 17 is provided on one side of the discharge pipe 10. There are several discharge pipes 10 and they are fixedly sleeved at the bottom of the grinding box 7. The discharge pipe 10 is connected to the grinding box 7. The output end of the high-torque motor 17 passes through the bottom of the grinding box 7 and is fixedly sleeved in the knife-marked grinding block 9. The upper surface of the knife-marked grinding block 9 is fixedly connected with a smooth bevel block 18. The high-torque motor 17 is fixedly installed at the bottom of the grinding box 7. The high-torque motor 17 has a large output torque, which is convenient for driving the knife-marked grinding block 9 fixedly connected to its output end to rotate. The knife-marked grinding block 9 is fixedly connected with a smooth bevel block 18. The smooth bevel block 18 has a smooth surface and the top is arranged at an angle.

[0027] The cylinder 15 and the high-torque motor 17 are electrically connected to the external terminal control device. When the material is crushed in the crushing box 1, the extension of the output end of the cylinder 15 is controlled to drive the two sealing partitions 16 to move backward at the bottom of the crushing box 1, thereby connecting the crushing box 1 with the grinding box 7, so that the crushed material falls into the grinding box 7, and the crushed material falls onto the smooth inclined block 18 installed on the upper side of the knife-marked grinding block 9. The smooth inclined block 18 has a smooth surface and an inclined top, so that the material can slide along the smooth inclined block 18 to between the knife-marked grinding ring 8 and the knife-marked grinding block 9. At this time, the material is passed through the grinding box 7. By starting the high-torque motor 17, the high-torque motor 17 drives the knife-marked grinding block 9 to rotate, thereby cooperating with the knife-marked grinding ring 8 to grind the material, and the ground material then flows downward through the gap between the knife-marked grinding ring 8 and the knife-marked grinding block 9. A discharge pipe 10 is provided just below the gap between the knife-marked grinding ring 8 and the knife-marked grinding block 9, so that the material flows out from the discharge pipe 10 under the rotation cooperation of the knife-marked grinding block 9, thereby facilitating the collection of the material and ensuring the effect of raw material processing. At the same time, a large amount of grinding time is not required, the time of raw material processing is reduced, and the use efficiency and effect of the grinding device are improved.

[0028] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
