[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-5 This utility model provides a technical solution:

[0024] A hard carbon grinding mill with a ceramic liner includes a grinding device 1, a motor 2, and a grinding roller 3. The grinding device 1 includes a grinding frame 101, and a plurality of grinding teeth 102 are arranged in a linear array on one side of the grinding frame 101. The top of the grinding teeth 102 is chamfered on both sides.

[0025] The interior of the grinding frame 101 is also lined with ceramic material. The ceramic lining plays a key protective role in the grinding process due to its excellent high hardness, high wear resistance and good chemical stability.

[0026] It can effectively resist the strong impact and friction of hard carbon materials on the inner wall of the grinding frame 101 during high-speed grinding, greatly reducing the wear of the grinding frame 101 and thus extending the service life of the equipment.

[0027] Meanwhile, the chemical stability of the ceramic lining ensures that no chemical reaction occurs when it comes into contact with hard carbon materials, effectively guaranteeing the purity of the hard carbon powder and avoiding the introduction of impurities due to chemical reactions, thereby ensuring the stability and reliability of product quality.

[0028] The chamfer on the crushing tooth 102 allows the hard carbon material to be cleverly guided into the notch when it enters the grinding device 1, just like opening a precise "guide channel" for the hard carbon material. This allows the hard carbon to smoothly reach the working area of ​​the grinding blade 301, greatly facilitating the crushing operation of the grinding blade 301 on the hard carbon and significantly improving the starting efficiency and accuracy of the entire grinding process.

[0029] The grinding roller 3 is provided with grinding blades 301. Each grinding blade 301 has two protruding ends. There are multiple grinding blades 301. Multiple grinding blades 301 are arranged in a linear array on the side wall of the grinding roller 3. There is an included angle of 30° or 150° between the protruding ends of two adjacent grinding blades 301.

[0030] The above design allows the pressure to be concentrated on the several grinding blades 301 that are performing the grinding operation during the grinding process.

[0031] When dealing with hard carbon materials with high hardness, this concentrated pressure characteristic can significantly enhance the crushing ability of the grinding blade 301 on hard carbon, effectively preventing the grinding blade 301 from getting stuck due to the excessive hardness of the hard carbon.

[0032] This design ensures the continuity and efficiency of the grinding process, enabling stable grinding operations even when handling high-hardness carbon materials.

[0033] When the grinding blade 301 rotates, it is recessed inward on the side facing the grinding tooth 102.

[0034] During the grinding process, the hard carbon material will slide along its surface under the pressure of the grinding blade 301.

[0035] The presence of the indentation effectively confines the hard carbon fiber below the indentation during sliding, preventing it from sliding out of the indentation.

[0036] This feature not only ensures that the hard carbon material is always within the effective range of the grinding blades 301, guaranteeing the sufficiency and uniformity of grinding, but also prevents the hard carbon from being ejected from the grinding device 1 during the high-speed rotating grinding process.

[0037] Once hard carbon is ejected, it will not only cause material loss, but may also pose a serious threat to the personal safety of operators.

[0038] Therefore, the recessed design not only improves grinding efficiency but also greatly enhances the safety of the equipment.

[0039] A motor 2 is installed at the rear of the grinding device 1. The output shaft of the motor 2 is connected to a drive wheel 201. The grinding roller 3 is connected to a driven wheel 202. A transmission belt 203 is laid between the drive wheel 201 and the driven wheel 202.

[0040] After the motor 2 starts, its output shaft drives the drive wheel 201 to rotate. Since the drive wheel 201 and the driven wheel 202 are connected by a transmission belt 203, power can be transmitted from the drive wheel 201 to the driven wheel 202, thereby causing the grinding roller 3 to start rotating.

[0041] During rotation, the grinding blades 301 make a circular motion, which affects the hard carbon material entering the grinding device 1.

[0042] Protective covers are provided on the outer sides of the motor 2, drive wheel 201, driven wheel 202 and transmission belt 203.

[0043] First, during the grinding process, hard carbon materials are ground into fine powder particles, i.e., carbon powder.

[0044] If these toner particles enter the motor 2, drive wheel 201, driven wheel 202, and transmission belt 203, they will gradually accumulate and adhere to the surfaces of these components, thereby hindering their normal operation.

[0045] For example, carbon powder entering the motor 2 may affect the heat dissipation performance of the motor 2, causing the motor 2 to overheat and shorten its service life; carbon powder adhering to the transmission belt 203 will increase the friction of the transmission belt 203, reduce the transmission efficiency, and may even cause the transmission belt 203 to slip or break.

[0046] The protective cover effectively prevents toner from entering, keeps these components clean, and ensures their smooth and reliable operation.

[0047] In addition, the protective cover can also provide safety protection for operators.

[0048] During equipment operation, components such as motor 2, drive wheel 201, and driven wheel 202 are in a state of high-speed rotation. If operators accidentally come into contact with these moving parts, it will cause serious personal injury accidents.

[0049] The protective cover isolates these dangerous components from the outside environment, preventing operators from accidentally touching them and thus ensuring the personal safety of the operators and enabling the equipment to operate stably in a safe environment.

[0050] Optionally, the crushing teeth 102 are slidably connected in the grinding frame 101, and the grinding frame 101 is rotatably connected to the screw 4. The screw 4 is provided with multiple pairs of reverse threads, and the crushing teeth 102 are arranged on the reverse threads.

[0051] One end of the screw 4 extends out of the grinding frame 101 and is located on the outside of the grinding frame 101. A worm gear 401 is provided at one end of the screw 4, and a worm 402 meshing with the worm gear 401 is provided on one side of the worm gear 401.

[0052] The top end of the worm gear 402 extends out from one side of the grinding frame 101 and is formed above the grinding frame 101. A knob 403 is installed on the top end of the worm gear 402.

[0053] When the position of the grinding teeth 102 needs to be adjusted, the operator turns the knob 403 located above the grinding frame 101.

[0054] The rotation of knob 403 causes worm 402 to start rotating. Since worm 402 and worm wheel 401 mesh with each other, the rotational motion of worm 402 is transmitted to worm wheel 401, causing worm wheel 401 to rotate accordingly.

[0055] The worm gear 401 is connected to one end of the screw 4, thereby further transmitting the rotational power to the screw 4, causing the screw 4 to rotate in the grinding frame 101.

[0056] The screw 4 is provided with multiple pairs of reverse threads, and the crushing teeth 102 are installed on these reverse threads.

[0057] When the screw 4 rotates, according to the principle of thread transmission, the crushing teeth 102 located on different reverse thread sections will move in relative or opposite directions in the axial direction of the screw 4.

[0058] For example, if a pair of crushing teeth 102 are located on the left-hand thread and the right-hand thread of the screw 4 respectively, then when the screw 4 rotates clockwise, one crushing tooth 102 will move towards the grinding roller 3, while the other will move away from the grinding roller 3.

[0059] In this way, the spacing between each grinding tooth 102 and the relative positional relationship between the grinding tooth 102 and the grinding blade 301 can be precisely adjusted.
