This invention enables repeated grinding of coating particles.

[0003] After investigation and analysis, the patent has the following drawbacks in actual use: The discharge port of this device is located at the bottom of the cylinder, which makes it difficult to completely discharge the material. This results in incomplete unloading, and the residual material needs to be manually cleaned by reaching into the cylinder. This not only increases the intensity of operation but also easily contaminates the subsequent grinding materials.

[0004] In summary, this application proposes a rotary grinding machine to solve the aforementioned problems. Utility Model Content

[0005] The purpose of this invention is to provide a tilting grinding machine that solves the problem that the discharge port is located at the bottom of the cylinder, which makes it difficult to completely discharge the material, resulting in incomplete unloading and the need for manual cleaning of residual material inside the cylinder, which not only increases the intensity of operation but also easily contaminates the material to be ground later.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rotary grinding machine, comprising: A base, with an auxiliary frame on top of the base, and a grinding cylinder on top of the auxiliary frame; The rotating assembly is set on the auxiliary frame. The rotating assembly includes a vertical plate, a motor and auxiliary rollers. The motor is fixedly installed on one side of the vertical plate. A connecting column is fixedly installed on the output shaft of the motor. The other end of the connecting column passes through the vertical plate and is fixedly installed on one side of the grinding cylinder. Two sets of auxiliary rollers are rotatably installed on the inner walls of both sides of the auxiliary frame and are symmetrically distributed front and back. The tilting assembly is mounted on the base and includes a threaded column, a guide rod, a movable plate, and a hinged connecting rod. The movable plate is mounted on the threaded column and the guide rod. Multiple sets of hinged connecting rods are hinged to the top of the movable plate, and the other end of the hinged connecting rods is hinged to the bottom of the vertical plate.

[0007] Preferably, the grinding cylinder is equipped with multiple sets of grinding balls; the grinding balls are made of high-hardness and wear-resistant material, which can break down and refine the material to be ground through impact and friction. The distribution density of the multiple sets of grinding balls is adapted to the volume of the grinding cylinder, ensuring that the material is in full contact with the grinding balls, improving grinding efficiency and uniformity, and avoiding the situation where some material is not ground.

[0008] Preferably, one side of the vertical plate is fixedly installed on one side of the auxiliary frame, and the outer wall of the grinding cylinder is in contact with the outer wall of the auxiliary roller; the vertical plate provides stable support for the motor and the grinding cylinder, ensuring that there is no shaking when the motor drives the grinding cylinder to rotate; the rolling contact between the auxiliary roller and the outer wall of the grinding cylinder provides guidance for the rotation of the grinding cylinder and limits its radial deviation, and reduces the rotational resistance of the grinding cylinder by replacing sliding friction with rolling friction, thereby reducing energy consumption and cylinder wall wear and extending the service life of the equipment.

[0009] Preferably, a discharge port is provided on one side of the grinding cylinder, and a hinged cover plate is hinged to one side of the grinding cylinder; the size of the discharge port is adapted to the discharge requirements of the ground material, and a rubber sealing ring is provided at the contact part between the hinged cover plate and the discharge port, which can ensure the sealing of the grinding cylinder when closed, and prevent material leakage or dust overflow during the grinding process; the hinged structure facilitates the quick opening and closing of the cover plate, and the material can be discharged through the discharge port after the grinding is completed, which is convenient to operate, does not require disassembling the grinding cylinder, and improves the unloading efficiency.

[0010] Preferably, the tilting assembly further includes a second motor. The second motor is fixedly installed on one inner wall of the base. The output shaft of the second motor is fixedly installed at one end of the threaded column, and the other end of the threaded column is rotatably installed on the other inner wall of the base. Guide rods are fixedly installed on the inner walls of both sides of the base. There are two sets of guide rods located on the front and rear sides of the threaded column.

Through the tilting design, the material can flow out of the grinding cylinder naturally under the action of gravity, reducing manual intervention and resistance during the discharge process. This allows the material to be discharged more smoothly, improving the discharge speed and efficiency. This effectively avoids the problem of incomplete unloading in existing devices and reduces the risk of material jamming or accumulation.

[0011] Preferably, connecting plates are rotatably mounted on both the front and rear sides of the base, and the connecting plates are fixedly mounted on the auxiliary frame. The connecting plates rotatably connect the base and the auxiliary frame to form a flipping structure, which allows the auxiliary frame to be manually pushed to flip around the rotation axis of the connecting plate and the base, thereby helping to adjust the tilt direction and angle of the grinding cylinder and further improving the ease of unloading. At the same time, the connecting plates provide stable support for the auxiliary frame, ensuring that the auxiliary frame does not shake during the grinding process and guaranteeing the stability of the grinding process.

[0012] Preferably, the inner wall of the grinding cylinder is polished and has multiple sets of raised ribs. Polishing the inner wall can reduce the frictional resistance between the material and the cylinder wall, and prevent the material from sticking to the cylinder wall and causing residue. When the grinding cylinder rotates, the raised ribs can drive the grinding balls and the material to make irregular movements, which can enhance the impact force of the grinding balls on the material and improve the grinding efficiency, especially suitable for grinding materials with high hardness.

At the same time, the tilt angle of the grinding cylinder can be precisely adjusted through the hinged connecting rod to adapt to different grinding trajectory optimization needs.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0018] Please see Figure 1-4 This utility model provides a technical solution: a flip-type grinding machine, including a base 1, a rotating component and an tilting component. An auxiliary frame 2 is provided above the base 1, and a grinding cylinder 3 is provided above the auxiliary frame 2. The rotating component is provided on the auxiliary frame 2 and includes a vertical plate 4, a motor 5 and auxiliary rollers 6. The motor 5 is fixedly installed on one side of the vertical plate 4, and a connecting column is fixedly installed on the output shaft of the motor 5. The other end of the connecting column passes through the vertical plate 4 and is fixedly installed on one side of the grinding cylinder 3. Two sets of auxiliary rollers 6 are rotatably installed on the inner walls of both sides of the auxiliary frame 2 and are symmetrically distributed front and back. The tilting component is provided on the base 1 and includes a threaded column 9, a guide rod 10, a moving plate 11 and a hinged connecting rod 12. The moving plate 11 is provided on the threaded column 9 and the guide rod 10. Multiple sets of hinged connecting rods 12 are hingedly installed on the top of the moving plate 11, and the other end of the hinged connecting rod 12 is hingedly installed to the bottom of the vertical plate 4.

[0019] Furthermore, the grinding cylinder 3 is equipped with multiple sets of grinding balls. The grinding balls are made of high-hardness and wear-resistant material, which can break down and refine the material to be ground through impact and friction. The distribution density of the multiple sets of grinding balls is adapted to the volume of the grinding cylinder 3 to ensure that the material is in full contact with the grinding balls, improve grinding efficiency and uniformity, and avoid the situation where some materials are not ground.

[0020] Furthermore, one side of the vertical plate 4 is fixedly installed with one side of the auxiliary frame 2, and the outer wall of the grinding cylinder 3 is in contact with the outer wall of the auxiliary roller 6. The vertical plate 4 provides stable support for the motor 5 and the grinding cylinder 3, ensuring that there is no shaking when the motor 5 drives the grinding cylinder 3 to rotate. The output shaft of the motor 5 is rigidly connected to one side of the grinding cylinder 3 through the connecting column. Therefore, when the motor 5 is running, it will directly drive the grinding cylinder 3 to rotate around its own axis. The two sets of auxiliary rollers 6 are always in contact with the outer wall of the grinding cylinder 3. The rolling contact between the auxiliary rollers 6 and the outer wall of the grinding cylinder 3 provides guidance for the rotation of the grinding cylinder 3 and limits its radial deviation. On the other hand, it reduces the rotational resistance of the grinding cylinder 3 by replacing sliding friction with rolling friction, thereby reducing energy consumption and cylinder wall wear and extending the service life of the equipment.

[0021] Furthermore, a discharge port is provided on one side of the grinding cylinder 3, and a hinged cover plate 7 is hinged to one side of the grinding cylinder 3. The size of the discharge port is adapted to the discharge requirements of the ground material. A rubber sealing ring is provided at the contact part between the hinged cover plate 7 and the discharge port. When closed, it can ensure that the grinding cylinder 3 is sealed and prevent material leakage or dust overflow during the grinding process. The hinged structure facilitates quick opening and closing of the cover plate. After grinding is completed, the material can be discharged through the discharge port by opening the cover plate. The operation is convenient and does not require disassembling the grinding cylinder, which improves the discharge efficiency. A snap-locking structure is provided on the hinged cover plate 7, which can lock the hinged cover plate 7 onto the grinding cylinder 3.

[0022] Furthermore, the tilting assembly also includes a second motor 8. The second motor 8 is fixedly installed on one inner wall of the base 1. The output shaft of the second motor 8 is fixedly installed at one end of a threaded column 9, and the other end of the threaded column 9 is rotatably installed on the other inner wall of the base 1. Guide rods 10 are fixedly installed on both inner walls of the base 1. There are two sets of guide rods 10 located on the front and rear sides of the threaded column 9. The threaded column 9 is threadedly installed on a movable plate 11, and the guide rods 10 are slidably installed on the movable plate 11. The second motor 8 drives the threaded column 9 to rotate synchronously, and the movable plate 11 is threadedly installed on the threaded column 9. Furthermore, the movable plate 11 is slidably connected to two sets of guide rods 10. When the threaded column 9 rotates, the movable plate 11 moves linearly along the axis of the threaded column 9 under the limiting action of the guide rods 10. When the movable plate 11 moves to the left, it drives the vertical plate 4 to move upward through the hinged connecting rod 12. Since the connecting plates 13 are rotatably installed on both the front and rear sides of the base 1, and the connecting plates 13 are fixedly connected to the auxiliary frame 2, the grinding cylinder 3 is tilted. Through the tilting design, the material can flow out of the grinding cylinder naturally under the action of gravity, reducing manual intervention and resistance in the discharge process. This allows the material to be discharged more smoothly, improving the discharge speed and efficiency, thereby effectively avoiding the problem of incomplete discharge in existing devices and reducing the risk of material jamming or accumulation. At the same time, the tilt angle of the grinding cylinder 3 can be precisely adjusted through the hinged connecting rod 12 to adapt to different grinding trajectory optimization needs.

[0023] Secondly, connecting plates 13 are rotatably installed on both the front and rear sides of the base 1, and the connecting plates 13 are fixedly installed on the auxiliary frame 2. The connecting plates 13 rotatably connect the base 1 and the auxiliary frame 2 to form a flipping structure. The auxiliary frame 2 can be manually pushed to flip around the rotation axis of the connecting plates 13 and the base 1, which helps to adjust the tilt direction and angle of the grinding cylinder 3 and further improves the convenience of unloading. At the same time, the connecting plates 13 provide stable support for the auxiliary frame 2 to ensure that the auxiliary frame 2 does not shake during the grinding process and to ensure grinding stability.

[0024] Secondly, the inner wall of the grinding cylinder 3 is polished and has multiple sets of raised ribs. The polished inner wall can reduce the frictional resistance between the material and the cylinder wall, and prevent the material from sticking to the cylinder wall and causing residue. When the grinding cylinder 3 rotates, the raised ribs can drive the grinding balls and the material to make irregular movements, which can enhance the impact force of the grinding balls on the material and improve the grinding efficiency, especially suitable for grinding materials with high hardness.

[0025] Working principle: First, open the hinged cover plate 7 on one side of the grinding cylinder 3, and put the material to be ground into the grinding cylinder 3. Then close the cover plate 7 to ensure a seal. At this time, the multiple sets of grinding balls inside the grinding cylinder 3 are in an initial horizontal state along with the cylinder body. Start the motor 5 in the rotating assembly. The output shaft of motor 5 is rigidly connected to one side of the grinding cylinder 3 through the connecting column. Therefore, when motor 5 is running, it will directly drive the grinding cylinder 3 to rotate around its own axis. The two sets of auxiliary rollers 6 are always in contact with the outer wall of the grinding cylinder 3, providing guidance for the rotation of the grinding cylinder 3 and preventing the cylinder body from deviating. When the grinding operation is completed, turn off motor 5 and start motor 8. Motor 8 drives the threaded column 9 to rotate in the same direction. As the threaded column 9 rotates, a movable plate 11 is threadedly installed on it, and the movable plate 11 is simultaneously slidably connected to two sets of guide rods 10. When the threaded column 9 rotates, the movable plate 11 moves linearly along the axis of the threaded column 9 under the limiting action of the guide rods 10. When the movable plate 11 moves to the left, it drives the vertical plate 4 to move upward through the hinged connecting rod 12. Since the base 1 has connecting plates 13 rotatably installed on both the front and rear sides, and the connecting plates 13 are fixedly connected to the auxiliary frame 2, the grinding cylinder 3 is tilted, the discharge port of the grinding cylinder 3 faces downward, the hinged cover plate 7 is opened, and the ground finished material is naturally discharged from the discharge port under the action of gravity, completing the unloading.

[0026] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
