Description

Technical Field

[0001] This utility model relates to the field of calcium powder grinding technology, and in particular to a calcium powder grinding machine. Background Technology

[0002] Calcium carbonate grinding mills are specialized equipment used to grind calcium carbonate raw materials to a specific particle size to meet the application needs of various industries. Their core function is to crush calcium carbonate particles through mechanical force and airflow impact, and to control the particle size distribution of the product through a grading system. They are widely used in plastics, rubber, papermaking, coatings, pharmaceuticals, and other fields.

[0003] To address this issue, patent CN221386808U discloses a grinding device for calcium powder processing, comprising a grinding table and grinding blocks. A grinding groove is formed at the top of the grinding table, and the grinding blocks are placed inside the grinding groove, with the size of the grinding groove matching that of the grinding blocks. The device also includes a rotating rod and a sieving groove. This invention controls a motor to operate, and the rotating rod drives the grinding blocks to rotate, performing the grinding of calcium carbonate. Simultaneously, the rotating rod drives a first bevel gear to rotate, which in turn drives a fixed rod to rotate, thereby causing a cam to rotate on the bottom side of a sieve plate. This vibration of the sieve plate allows for the screening of large-sized calcium carbonate raw materials in the sieving groove, solving the problem that existing grinding devices for calcium powder processing cannot effectively screen the size of the calcium carbonate raw materials to be ground, thus affecting grinding efficiency.

[0004] The existing technical solutions mentioned above have the following drawbacks: although calcium powder can be ground, the gap between the grinding block and the grinding tank is a fixed value, which means that the calcium powder particles in the gap cannot be squeezed and ground, making it inconvenient to stably grind the calcium powder, thus affecting the quality of calcium powder grinding. Utility Model Content

[0005] The purpose of this invention is to provide a calcium powder grinding machine to solve the problem that existing calcium powder grinding machines are inconvenient to reliably grind calcium powder.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a calcium powder grinding machine, including a processing table;

[0007] A grinding disc is fixedly connected to the top of the processing table, an L-shaped bracket is fixedly connected to the top of the processing table, and a grinding mechanism is fixedly connected to the top of the L-shaped bracket.

[0008] The grinding mechanism includes a frame plate fixedly installed on the top of an L-shaped bracket. A drive motor is fixedly connected to the top of the frame plate. The output shaft of the drive motor is fixedly connected to a first rotating rod via a coupling. A first gear is fixedly connected to one end of the first rotating rod. A second gear is movably connected to the outer wall of the first gear. A second rotating rod is fixedly connected to the inner wall of the second gear. A receiving block is fixedly connected to the bottom end of the second rotating rod.

[0009] Preferably, the receiving block has a movable groove inside, a rotating shaft is movably connected inside the receiving block, a movable block is fixedly connected to the outer wall of the rotating shaft, and a grinding rod is fixedly connected to the outer wall of the rotating shaft.

[0010] Preferably, the first gear forms a rotating structure with the L-shaped bracket via the first rotating rod, and the first gear meshes with the second gear, so that the rotation of the first gear can drive the rotation of the second gear.

[0011] Preferably, the second gear forms a rotating structure with the L-shaped bracket via the second rotating rod, and the receiving block forms a rotating structure with the L-shaped bracket via the second rotating rod, which allows the receiving block to rotate along the L-shaped bracket.

[0012] Preferably, the receiving block forms a rotating structure with the grinding rod via a rotating shaft, and the movable block is located in the movable groove, which allows the grinding rod to rotate along the receiving block and grind the calcium powder in the grinding disc.

[0013] Preferably, an assembly mechanism is fixedly connected to the bottom of the processing table. The assembly mechanism includes a limiting ring fixedly installed at the bottom of the processing table. A threaded groove is opened inside the limiting ring. A threaded block is movably connected to the inner wall of the limiting ring. A receiving rod is fixedly connected to the top of the threaded block. A cylindrical plug is fixedly connected to the top of the receiving rod.

[0014] Preferably, the limiting ring is threadedly connected to the threaded block through a threaded groove, and the cylindrical plug is engaged with the grinding disc. The grinding calcium powder in the grinding disc can be discharged by disassembling the cylindrical plug.

[0015] The advantages of the calcium powder grinding machine provided by this utility model are as follows:

[0016] By setting up a grinding disc and grinding mechanism, starting the drive motor can make the first gear rotate, which in turn makes the second gear rotate, driving the receiving block fixedly connected to one end of the second rotating rod to rotate. Under the action of the rotating shaft, the grinding rod can rotate along with the receiving block while rotating on its own along the receiving block, which facilitates the stable grinding of calcium powder in the grinding disc.

[0017] Furthermore, since the grinding rod is tilted, it can always be in contact with the inner wall of the grinding disc, which further improves the quality and precision of grinding.

[0018] Furthermore, since the size of the first gear is smaller than that of the second gear, the rotational stability of the second gear can be improved, thereby further improving the stability of the grinding rod grinding the calcium powder.

[0019] Furthermore, the combined effect of the movable groove and the movable block can improve the stability of the grinding rod's rotation grinding.

[0020] By rotating the threaded block through the set grinding disc and assembly mechanism, the threaded block can be disassembled from the limiting ring, allowing the columnar plug fixedly connected to the top of the receiving rod to rotate and move out along the grinding disc, which facilitates the quick feeding of the calcium powder that has been ground in the grinding disc.

[0028] Please see Figures 1-5 The present invention provides a calcium powder grinding machine, including a processing table 1.

[0029] Reference Figure 1 , Figure 2 and Figure 3 As shown, a grinding disc 2 is fixedly connected to the top of the processing table 1, an L-shaped bracket 3 is fixedly connected to the top of the processing table 1, and a grinding mechanism 4 is fixedly connected to the top of the L-shaped bracket 3.

[0030] By placing calcium powder in the grinding disc 2 and starting the drive motor 42, the first gear 44, which is fixedly connected to the outer wall of the first rotating rod 43, can rotate. Since the first gear 44 is meshed with the second gear 45, the second gear 45 can rotate, which in turn drives the receiving block 47, which is fixedly connected to one end of the second rotating rod 46, to rotate. Since the grinding rod 48 is in contact with the inner wall of the grinding disc 2 and the movable block 473 is located in the movable groove 471, as the receiving block 47 rotates, under the action of the rotating shaft 472, the grinding rod 48 can be driven to rotate along with the receiving block 47 while rotating on its own axis, so that the grinding rod 48 grinds the calcium powder in the grinding disc 2.

[0031] Reference Figure 2 , Figure 4 and Figure 5 As shown, an assembly mechanism 5 is fixedly connected to the bottom of the processing table 1. The assembly mechanism 5 includes a limiting ring 51 fixedly installed at the bottom of the processing table 1. A threaded groove 52 is opened inside the limiting ring 51.
