Description

Technical Field

[0001] The present application relates to the technical field of sand mill pin rotors, and more specifically, to a nano grinding machine pin rotor structure. Background Art

[0002] A sand mill, also known as a bead mill, is a wet ultrafine grinding device primarily used for wet grinding of liquid chemical products. It is the most adaptable, advanced, and efficient grinding equipment. The rotor, a crucial component of a sand mill, has a significant impact on its performance due to its structure.

[0003] Currently, in existing sand mill rotor structures, the rotor pins are typically secured to the rotor axis using screws. A spacer ring is installed on the screw to isolate the screw from the material, preventing direct contact between the two. Furthermore, the spacer ring has a toothed structure, which is driven by the main shaft to perform the grinding operation. However, this rotor structure presents numerous problems. The screw-locked spacer ring is cumbersome to install, and the toothed structure on the spacer ring complicates its machining. Furthermore, stress concentration during grinding can easily cause the spacer ring to rupture, allowing grinding media and material to enter the rotor mounting surface, making rotor disassembly and assembly difficult. In severe cases, this can damage the pins, impacting production efficiency and failing to meet grinding requirements.

[0004] Therefore, how to provide a nano-grinder rod pin rotor structure that is easy and efficient to install, can effectively prevent materials and grinding media from entering the rotor mounting surface, enhance the durability of the rotor, and reduce the cost of use has become a technical problem that needs to be urgently solved by those skilled in the art.

[0111] As described above, the nano-grinder rod pin rotor structure provided by the embodiment of the utility model solves the problem of cumbersome rod pin locking in the traditional rotor structure, solves the problem of the toothed structure of the rotor spacer sleeve, which causes stress concentration and easy rupture, solves the problem that the spacer sleeve cannot be added with a sealing ring, which causes zirconium beads and materials to easily enter the rotor mounting surface and make disassembly and assembly difficult, and solves the problem of complex processing of the traditional spacer sleeve. In the rod-pin rotor structure of the nano-grinder, its main structure is composed of the first rotor mechanism 1, the second rotor mechanism 3 and the intermediate mechanism 2 arranged between the first rotor mechanism 1 and the second rotor mechanism 3. It uses a split structure, which effectively reduces the cost; wherein, the first rotor mechanism 1 includes the rotor shaft 4, the first pressure cover mechanism 5, the first rod-pin assembly 7, the spacer frame 8 and the first spacer sleeve 9, the first pressure cover mechanism 5 is installed on the front end face of the rotor shaft 4 by fasteners to protect the rotor shaft 4, a spindle mounting hole is provided on the rotor shaft 4, the external rotating spindle passes through the first pressure cover mechanism 5 and is installed in the rotor shaft 4, driving the entire rotor structure to rotate and realizing power transmission, a plurality of groups of the first rod-pin assemblies 7 are evenly spaced on the side wall of the rotor shaft 4, the first rod-pin assembly 7 is clamped with the rotor shaft 4 through the groove 6, and the spacer frame is installed between the two first rod-pin assemblies 7 The frame 8 presses the first rod pin assembly 7 and fixes it on the rotor shaft 4, which is efficient and convenient to install. The first spacer sleeve 9 is sleeved on the spacer sleeve skeleton 8, which can effectively avoid the grinding medium and material from entering the installation surface of the rotor shaft 4 during the grinding operation, thereby enhancing the practicality of the rotor structure. For the second rotor mechanism 3, its main structure includes the rotor skeleton 10, the second rod pin assembly 11, the second spacer sleeve 12 and the second pressing cover mechanism 13. The rotor skeleton 10 is connected to the rotor shaft 4 through the intermediate mechanism 2. The second rod pin assembly 11 and the second spacer sleeve 12 are mutually overlapping structures with the rotor skeleton 10. The second rod pin assembly 11 and the second spacer sleeve 12 are sleeved on the rotor skeleton 10 to achieve convenient installation. The second pressing cover mechanism 13 is set at the rear end of the rotor skeleton 10, which can not only press the rod pin assembly and the spacer sleeve set on the rotor skeleton 10, but also fix the installation position of the rotor skeleton 10. It can be seen that the technical solution provided by the present invention is convenient and efficient to install compared with the prior art, can effectively prevent materials and grinding media from entering the rotor installation surface, enhance the durability of the rotor, and reduce the cost of use.
