Description

Technical Field

[0001] This utility model relates to the field of ball mill technology, and in particular to a vibration table mechanism for a vibratory ball mill with a separate vibration motor and grinding cylinder. Background Technology

[0002] A vibratory ball mill is a high-efficiency pulverizing device that uses high-frequency vibration to drive grinding media to impact, rub, and shear materials. It mainly consists of a frame, vibrator (including an eccentric block or vibratory motor), grinding jar (cylinder), cooling system, grinding media (steel balls, steel rods, etc.), and control system. The vibratory motor or eccentric block drives the grinding jar to generate high-frequency vibration (typically 16-20 Hz, amplitude 7-14 mm), causing the grinding media to collide violently with the material, achieving a combined effect of impact, compression, and friction. The vibration energy transfer efficiency is 2-5 times that of traditional ball mills, making it particularly suitable for preparing micron- to nano-scale ultrafine powders.

[0003] Chinese utility model patent CN118491625A discloses a dual-excitation dual-rigid-body ball mill, sodium-ion battery cathode material production equipment and process, including an outer rigid body, an inner rigid body, an elastic vibration platform, and two vibration motors. The outer rigid body includes a horizontal grinding cylinder with a feed inlet at the top and a discharge outlet at one end along its axial direction. The inner rigid body includes a stirring blade rotatably disposed inside the grinding cylinder, with the rotation axis of the stirring blade parallel to and offset from the central axis of the grinding cylinder. The elastic vibration platform supports the grinding cylinder, and the two vibration motors are distributed on both sides of the grinding cylinder to drive the grinding cylinder to vibrate. This ball mill is a horizontal ball mill. During installation, the grinding cylinder needs to be pre-fixed to the upper base plate, and then the vibration motors are installed on both sides of the grinding cylinder. During discharge, the material is discharged through the outlet on one side of the grinding cylinder. To ensure that the material is discharged as completely as possible, the grinding cylinder can be rotated and flipped for feeding. However, this cannot be achieved using the upper base plate structure disclosed in this patent. In addition, the installation position of the vibrating motor relative to the grinding cylinder will also have different effects on the subsequent vibration of the grinding cylinder and the abrasive. However, the above-mentioned upper base plate structure cannot achieve independent and multi-directional free installation of the vibrating motor, which will affect the subsequent working effect.

[0004] Therefore, a new technical solution is urgently needed to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this utility model is to overcome the problems of the prior art and provide a vibration table mechanism for a vibratory ball mill with a separate vibration motor and grinding cylinder. This mechanism solves the technical problems of existing base plates for installing grinding cylinders being unable to adapt to the rotation of the grinding cylinder for material feeding, as well as the compact space, lack of independent installation space for the grinding cylinder and vibration motor, and the limited installation angle of the vibration motor, which affects the vibration abrasive effect.

[0006] The above objectives are achieved through the following technical solutions:

[0007] A vibration table mechanism for a vibratory ball mill with a separate vibration motor and grinding cylinder includes a vibration table plate. The vibration table plate is provided with a vibration motor mounting position and a grinding cylinder mounting position. A grinding cylinder through groove is provided in the grinding cylinder mounting position to allow the grinding cylinder to rotate freely. Grinding cylinder support positions are symmetrically arranged on the left and right sides of the grinding cylinder through groove. A shaft locking assembly is provided in the grinding cylinder support position to movably connect the grinding cylinder shafts at both ends of the grinding cylinder.

[0008] Furthermore, the length of the vibration motor mounting position is equal to the length of the grinding cylinder mounting position.

[0009] Furthermore, the vibration table plate has a keel structure.

[0010] Furthermore, the grinding cylinder support has a C-shaped groove that matches the shape of the grinding cylinder shaft.

[0011] Furthermore, the pivot locking assembly includes a C-shaped bushing that can engage with the C-shaped groove and form an O-shaped sleeve hole.

[0012] Furthermore, the rotary locking assembly also includes a pressure arm support disposed on the surface of the vibration table plate. A pressure arm and a pressure arm cylinder are hinged on the pressure arm support. One end of the pressure arm is connected to a pressure head that can press the C-shaped bushing, and the other end is provided with an upper pressure arm slide that allows a roller trolley connected to the piston end of the pressure arm cylinder to slide. The vibration table plate is also provided with a lower pressure arm slide corresponding to the upper pressure arm slide. By sliding the roller trolley within the upper pressure arm slide and the lower pressure arm slide, the lifting and lowering control of the pressure arm can be realized.

[0013] Furthermore, the upper pressure arm slide and the lower pressure arm slide are respectively provided with trolley inclined grooves, and the inclination angle of the trolley inclined grooves is 30° to 60°.

[0014] Furthermore, the roller trolley includes a push block connected to the piston end of the pressure arm cylinder, and the push block is symmetrically provided with an upper roller group and a lower roller group.

[0015] Furthermore, a downward arc-shaped protrusion is provided below the vibration table plate corresponding to the grinding cylinder support position.

[0016] Furthermore, an elastic component is provided below the vibration table plate for elastic connection between the vibration table plate and the support below.

[0017] This utility model provides a vibration table mechanism for a vibratory ball mill with a separate vibratory motor and grinding cylinder. By setting a vibratory motor mounting position and a grinding cylinder mounting position with a through groove on the vibration table plate, it can achieve free installation of the vibratory motor at multiple angles and precise assembly of the grinding cylinder. This separate vibration table mechanism is not only simple in structure and can meet the installation requirements of grinding cylinders of various specifications, but also has good fixing effect and excellent vibration reduction effect.

[0033] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. The described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0034] like Figures 1 to 7 As shown, this solution provides a vibration table mechanism for a vibratory ball mill with a separate vibration motor and grinding cylinder, including a vibration table plate 1. The vibration table plate 1 is provided with a vibration motor mounting position 101 and a grinding cylinder mounting position 102. A grinding cylinder through groove 105 is provided in the grinding cylinder mounting position 102 to allow the grinding cylinder 3 to rotate freely. Grinding cylinder support positions 103 are symmetrically arranged on the left and right sides of the grinding cylinder through groove 105. A shaft locking assembly 2 is provided in the grinding cylinder support position 103 to movably connect the grinding cylinder shafts 301 at both ends of the grinding cylinder 3.

[0035] Specifically, this vibration table mechanism can achieve free installation of the vibration motor 4 through the independent vibration motor mounting position 101, and can achieve movable installation of the grinding cylinder 3 through the independent grinding cylinder mounting position 102. It can also achieve rapid positioning of the grinding cylinder shaft 301 through the grinding cylinder support position 103, thus achieving precise assembly. Finally, the grinding cylinder 3 and the vibration table plate 1 are movably connected through the shaft locking assembly 2.

[0036] It should be noted that, in this embodiment, the length of the vibration motor mounting position 101 is equal to the length of the grinding cylinder mounting position 102. Under this structure, the vibration motor 4 can be placed at any position of the vibration motor mounting position 101, such as corresponding to the left, middle or right section of the grinding cylinder mounting position 102, thereby satisfying that different mounting positions of the vibration motor 4 relative to the grinding cylinder 3 can bring different abrasive effects to the subsequent vibration abrasive of the grinding cylinder 3.

[0037] Furthermore, the vibrating table 1 has a keel structure 5. Non-uniform vibration of the vibrating table 1 can lead to chaotic movement trajectories of the grinding media. This keel structure is the main load-bearing and force-transmitting skeleton of the vibrating table. Through grid or frame design, it disperses the load, suppresses vibration deviation, and ensures efficient transmission of excitation force. By balancing the vibration phase difference in different areas of the table, it reduces waveform distortion, makes the movement of the grinding media more regular, and improves the uniformity of grinding. A sound insulation layer can also be embedded in the keel structure to cut off the sound bridge transmission path of vibration through the metal structure and reduce noise leakage.

[0038] In this embodiment, a downward arc-shaped protrusion 104 is provided below the vibration table plate 1 corresponding to the grinding cylinder support position 103, which is used to strengthen the support of the grinding cylinder 3.

[0039] As an embodiment of this solution, the arc-shaped protrusion 104 has a cavity, and several reinforcing ribs are provided in the cavity to improve the support strength of the grinding cylinder support position 103.

[0040] An elastic component 7 is also provided below the vibration table 1 for elastic connection between the vibration table 1 and the lower support, thereby further reducing the vibration impact of the vibration table 1 on the lower support during operation and achieving the effect of vibration reduction. As a specific embodiment of this solution, the elastic component 7 is a spring.

[0041] like Figures 1-3 As shown, the grinding cylinder support 103 has a C-shaped groove that matches the shape of the grinding cylinder shaft 301. The grinding cylinder shaft and the C-shaped groove are connected by a shaft bearing 6, thereby enabling the grinding cylinder shaft 301 to rotate freely relative to the C-shaped groove.

[0042] like Figures 4-7 As shown, in this embodiment, the rotating shaft locking assembly 2 includes a C-shaped bushing 201 that can engage with the C-shaped groove and form an O-shaped sleeve hole. The C-shaped bushing can be connected to the C-shaped groove by bolts.

[0043] In addition, the rotary locking assembly 2 also includes a pressure arm support 202 disposed on the surface of the vibration table 1. A pressure arm 203 and a pressure arm cylinder 204 are hinged on the pressure arm support 202. One end of the pressure arm 203 is connected to a pressure head 205 that can press the C-shaped bushing 201, and the other end is provided with an upper pressure arm slide 207 that allows the piston end of the pressure arm cylinder 204 to slide. The vibration table 1 is also provided with a lower pressure arm slide 208 corresponding to the upper pressure arm slide 207. The lifting and lowering control of the pressure arm 203 can be realized by the sliding of the roller trolley 206 in the upper pressure arm slide 207 and the lower pressure arm slide 208.

[0044] Specifically, the roller trolley 206 is driven forward by the pressure arm cylinder 204. Since the lower pressure arm slide 208 is fixed on the vibration table 1, the upper pressure arm slide 207 will lift after being pushed upward and rotate relative to the junction point with the pressure arm support 202. Then, the other end of the pressure arm 203 drives the pressure head 205 to move downward, pressing one side of the C-shaped bushing 201 to firmly fix it on the C-shaped groove. This ensures that there will be no loosening or displacement during long-term vibration operation, thus ensuring the stability of the grinding cylinder 3 connection.

[0045] The upper pressure arm slide 207 and the lower pressure arm slide 208 are respectively provided with trolley inclined grooves 209. The inclination angle of the trolley inclined grooves 209 is 30° to 60°. The extension lines of the trolley inclined grooves 209 of the upper pressure arm slide 207 and the trolley inclined grooves 209 of the lower pressure arm slide 208 are compared at a point to form an angle.

[0046] like Figure 4 and Figure 7 As shown, in this embodiment, the roller trolley 206 includes a push block 210 connected to the piston end of the pressure arm cylinder 204. The push block 210 is symmetrically provided with an upper roller group 211 and a lower roller group 212. The upper roller group 211 can act on the trolley inclined groove 209 on the upper pressure arm slide 207, and the lower roller group 212 can act on the trolley inclined groove 210 on the lower pressure arm slide 208. Through the synchronous drive of the upper roller group 211 and the lower roller group 212, the opening and closing of the upper pressure arm slide 207 and the lower pressure arm slide 208 can be realized.

[0047] The above description is only for illustrating the embodiments of this utility model and is not intended to limit this utility model. For those skilled in the art, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
