[0019] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0020] like Figures 1-4 The vertical ring die pellet mill shown includes a base 1, a lower platen housing 2, and an upper platen cover 3. The lower platen housing 2 is fixedly connected to the upper end face of the base 1, and the upper platen cover 3 is rotatably hinged to the upper end face of the lower platen housing 2. It also includes:

[0021] A grinding wheel 13 is rotatably connected to the lower housing 2. A servo motor 12 is fixedly connected to the lower inner wall of the base 1. The output end of the servo motor 12 is fixedly connected to the lower end face of the grinding wheel 13 to drive the grinding wheel 13 to rotate.

[0022] Two H-shaped sleeves 8 are rotatably connected to the upper cover 3. A rotating shaft 10 is rotatably connected to each of the two sleeves 8 through a bearing 9. A pressure roller 11 is fixedly connected to the lower end face of each of the two rotating shafts 10. The two pressure rollers 11 are inserted into the grinding mold 13 and cooperate with the inner wall of the grinding mold 13 to crush waste wood.

[0023] An adjustment mechanism is located between the sleeve 8 and the upper cover 3. The adjustment mechanism is used to eccentrically adjust the distance between the two pressure rollers 11 and the mold 13.

[0024] When the device is in operation, the servo motor 12 is turned on. The output end of the servo motor 12 rotates, driving the grinding mold 13 to rotate inside the lower casing 2. The inner wall of the grinding mold 13 and the two pressure rollers 11 crush the waste wood, thereby turning the waste wood into wood pellets.

[0025] In this solution, the grinding wheel 13 rotates actively and cooperates with the two pressure rollers 11 to crush waste wood. The bearing 9, which is built into the pressure roller 11 in the prior art, is placed on the upper side of the pressure roller 11. Since the bearing 9 is inside the sleeve 8, it helps to reduce the temperature of the bearing 9 during operation, thereby extending the service life of the bearing 9. In this solution, the active rotation of the pressure roller 11 in the prior art is changed to active rotation of the grinding wheel 13, which makes it easier to set the servo motor 12 on the lower side of the grinding wheel 13, thereby saving space in the upper cover 3. This also makes it easier to set the bearing 9 and the sleeve 8 in a mutually cooperating external manner. This is different from the prior art and also achieves a bearing cooling effect that the prior art cannot achieve.

[0026] It is worth mentioning that the circumferential surface of the rotating shaft 10 is fixedly connected to the inner wall of the inner ring of the bearing 9, and the outer wall of the outer ring of the bearing 9 is fixedly connected to the sleeve 8, so that the rotating shaft 10 can rotate with the sleeve 8 and cannot move up and down relative to the sleeve 8. Since the sleeve 8 is designed in the H shape, the sleeve 8 can rotate in the circular hole of the upper disc cover 3 and cannot move up and down relative to the upper disc cover 3.

[0027] Specifically, the adjusting mechanism comprises two gear rings 7, which are fixedly connected to the upper part of the circumferential surface of the sleeve 8. The through holes in the two sleeves 8 are arranged at eccentric positions. The two rotating shafts 10 are rotatably connected to the through holes of the two sleeves 8 at the eccentric positions through the two bearings 9. The upper end surface of the upper disc cover 3 is threadedly connected with four jackscrews 5. The outer sides of the two gear rings 7 are engaged with the inner gear sleeve plates 6. The four jackscrews 5 press the two inner gear sleeve plates 6 to adjust the rotation angle of the two inner gear sleeve plates 6.

[0028] In work, with long-term use of the device, the long-term wear of the pressure roller 11 and the grinding tool 13 will cause the gap to become larger and larger. The rotation of the jackscrew 5 to press the inner gear sleeve plate 6 can realize the rotation of the inner gear sleeve plate 6. The rotation of the inner gear sleeve plate 6 drives the rotation of the gear ring 7. The rotation of the gear ring 7 drives the rotation of the sleeve 8. Since the through holes in the sleeve 8 are arranged at eccentric positions, the rotation of the sleeve 8 can adjust the distance between the pressure roller 11 and the grinding tool 13, thereby facilitating the long-term use of the device.

[0029] Specifically, the two oil cylinders 4 are rotatably connected between the base 1 and the upper disc cover 3. The upper disc cover 3 is driven to open and close through the two oil cylinders 4.

[0030] In work, the extension and shortening of the output end of the oil cylinder 4 can realize the rotation of the opening and closing of the upper disc cover 3, which is more labor-saving.

[0031] The working principle of the utility model:

[0032] When the device needs to be used, the servo motor 12 is turned on. The output end of the servo motor 12 rotates to drive the grinding tool 13 to rotate in the lower disc shell 2. The inner wall of the grinding tool 13 and the two pressure rollers 11 realize the rolling and grinding of the waste wood, so as to make the waste wood into wood particles.

[0033] The basic principle, main features and advantages of the utility model are shown and described above. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions in the specification are only the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model can have various changes and improvements. These changes and improvements all fall within the scope of the claimed utility model. The protection scope of the utility model is defined by the appended claims and their equivalents.
