It should be understood that the specific embodiments described herein are only part of the embodiments of the present invention, not all of them, and are only used to explain the embodiments of the present invention and are not intended to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0020] Example 1
[0021] See also Figure 1-Figure 3 The utility model provides a technical solution: a wood grinding device for papermaking, comprising: a material receiving box 1, a material receiving pool 2 is opened on the upper surface of the material receiving box 1, the material receiving pool 2 is used to store the ground wood, a wood grinding mechanism 3 is arranged in the material receiving pool 2, the wood grinding mechanism 3 is used to cut and grind the wood, the wood grinding mechanism 3 includes a top shell 6, an abrasive assembly 14, a bottom shell 4, a rectangular shell 8 and its internal structure, the bottom shell 4 is fixedly installed at the bottom of the material receiving pool 2, the bottom shell 4 mainly plays a certain supporting role, the top shell 6 is fixedly connected to the bottom shell 4 by a connecting block, and the top shell 6 also plays a role It has a certain supporting function, which is mainly to provide a support and placement point for the placement of logs. The abrasive assembly 14 is installed between the bottom shell 4 and the top shell 6, and extends into the top shell 6 and the bottom shell 4 respectively. The rectangular shell 8 is fixedly installed on one side of the bottom shell 4. The rectangular shell 8 is used to protect the second motor 16 and the rotating wheel 17 to ensure that they will not be affected by the broken wood. A groove 13 is provided on the upper surface of the bottom shell 4. The groove 13 is used to set the abrasive assembly 14. The side wall of the groove 13 is provided with a channel 15. The channel 15 is used to pass the belt 10 to facilitate the transmission of kinetic energy.
[0022] During actual use, the wood is put in through the top of the top shell 6, and the wood will be cut by the wood grinding mechanism 3. Each piece of wood cut will be ground on the surface of the grinding plate. The grinding process will throw the ground wood into the material receiving pool 2. During this process, the second motor 16 will drive the grinding disc 9 to move through the belt 10, and the cutting disc 5 will move in the opposite direction.
[0023] Example 2
[0024] See also Figure 1-Figure 3On the basis of the first embodiment, the abrasive assembly 14 includes a cutting disc 5, a grinding disc 9 and a first motor 12. The first motor 12 is fixedly mounted in the bottom wall of the groove 13. The output end of the first motor 12 passes through the bottom wall of the groove 13 and is rotatably connected thereto. The grinding disc 9 is mounted on the output end of the first motor 12 and is rotatably connected thereto. Therefore, the first motor 12 cannot drive the concave disc to move. The movement of the concave disc is driven by the belt 10. The grinding disc 9 is arranged in the groove 13 and is rotatably connected thereto. This ensures that the grinding disc 9 will not be easily stuck by wood chips. The cutting disc 5 is mounted on the upper surface of the grinding disc 9. The grinding disc 9 is fixedly connected to the output end of the first motor 12 through a rotating shaft. Therefore, the first motor 12 can drive the cutting disc 5 to rotate. The rotation direction of the cutting disc 5 is the inclined direction of the cutting hole 18 from bottom to top. A first annular groove 11 is provided on one side of the grinding disc 9. The first annular groove 11 is arranged in the middle of the grinding disc 9 for working through external equipment. A plurality of cutting holes 18 are provided on the cutting disc 5. Each cutting hole 18 is arranged at an angle. A second motor 16 is fixedly installed inside the rectangular shell 8. The second motor 16 is used to drive the grinding disc 9 to rotate. The output end of the second motor 16 is fixedly connected to a rotating wheel 17. The rotating wheel 17 is used to transmit the power of the second motor 16. A belt 10 is provided on one side of the rotating wheel 17. One end of the belt 10 is sleeved on the rotating wheel 17, and the other end of the belt 10 passes through the channel 15 and is sleeved on the grinding disc 9.
[0025] When the cut wood block is in the inclined cutting hole 18, the output end of the second motor 16 drives the rotating wheel 17 to rotate, and the rotating wheel 17 drives the grinding wheel 9 to rotate through the belt 10. The rotation of the grinding wheel 9 grinds the wood in the cutting hole 18. The cooperation of the first motor 12 and the second motor 16 allows the grinding wheel 9 and the cutting disc 5 to rotate in opposite directions, making the grinding process convenient and efficient.
[0026] Example 3
[0027] See also Figure 2 and Figure 4On the basis of the second embodiment, a cutting knife 19 is installed on the top of each cutting hole 18, and the cutting knife 19 prepares for the wood cutting process of the cutting disc 5. A discharge port 20 is opened on one side of each cutting hole 18. The cut wood cannot be thrown out from the discharge port 20. Only the wood after grinding can be thrown out from the discharge port 20. The upper surface of the grinding disc 9 is provided with a plurality of grinding wood grains 24. The existence of the grinding wood grains 24 effectively improves the speed of grinding wood. The upper surface of the grinding disc 9 is provided with a second annular groove 23. The second annular groove 23 is provided on the upper surface of the grinding disc 9. 3 is slidably connected to a rotating ring 21, which can rotate in the second annular groove 23. A plurality of balls 22 are embedded on both sides of the rotating ring 21. The arrangement of the balls 22 is to make the rotation between the grinding disc 9 and the cutting disc 5 smooth, so as to ensure that the two are relatively smooth during the cooperation process and only generate very small rolling friction. The upper surface of the top shell 6 is provided with a plurality of through holes 7. The arrangement of the plurality of through holes 7 allows multiple pieces of wood to be placed at a time, and the operation is simple. The wood can be vertically inserted into the through holes 7.
[0028] During actual use, the wood is first inserted into the through hole 7, and then the first motor 12 will drive the movement of the cutting disc 5, and the second motor 16 will drive the movement of the grinding disc 9 through the belt 10. The reverse movement of the cutting disc 5 and the grinding disc 9 causes the wood blocks cut by the cutting disc 5 to be continuously ground by the grinding disc 9 in the cutting hole 18 until they are all ground into powder and debris. The ground powder and debris will be thrown out from the discharge port 20, and the thrown powder and debris will fall into the receiving pool 2.
[0029] 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.
