Description

Technical Field

[0001] This utility model relates to the field of powder production lines, and in particular to a modifying machine used in powder production lines. Background Technology

[0002] In existing powder modification production, the powder fails to fully integrate and coat with the modifier, resulting in the quality not reaching the ideal level. Utility Model Content

[0003] To address the aforementioned issues, this technical solution provides a modifier for use in powder production lines.

[0004] To achieve the above objectives, the technical solution is as follows:

[0005] A modification machine used in powder production lines, comprising a disassembly device body and a fixing body;

[0006] The main body of the peeling device includes a peeling end spindle, one end of which is provided with a peeling end rotor, the peeling end rotor is provided with a needle pressure plate, and the other end of the peeling end spindle is driven by a driver through the peeling end rotor.

[0007] The fixed body includes a fixed end spindle, one end of which is provided with a fixed end rotor, and the fixed end rotor is provided with a needle that cooperates with the needle pressure plate. The other end of the fixed end spindle is also driven by a driver.

[0008] A cavity is provided between the body of the opening device and the fixed body.

[0009] In some embodiments, the main shaft at the opening end is fitted with a deep groove ball bearing, and the main shaft at the opening end is also provided with a bearing housing.

[0010] In some embodiments, the cavity is provided with an injection chamber.

[0011] In some embodiments, the body of the disassembly device is further provided with a tensioning screw for adjusting the tension of the belt.

[0012] In some embodiments, the opening device body is provided with a plurality of handwheels.

[0013] The beneficial effects of this application are:

[0014] This application utilizes the friction between a high-speed rotating needle disc and a fixed needle seat to subject the powder material to strong impact and shear forces within the needle disc cavity, achieving deagglomeration and dispersion. The high-speed motion of the needle disc (typically reaching thousands of revolutions per minute) creates a vortex two-phase flow within the cavity, where the material and modifier are thoroughly mixed and undergo surface chemical reactions. This ensures uniform force on the material and adapts to powder modification scenarios with varying particle size requirements, achieving complete coating and guaranteeing product quality.

[0019] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] Please refer to Figure 1-3 As shown, the modifier used in the powder production line includes a disassembly device body 1 and a fixing body 2.

[0021] The main body 1 of the peeling device includes a peeling end spindle 3, one end of which is provided with a peeling end rotor 4, the peeling end rotor 4 is provided with a needle pressure plate 5, and the other end of the peeling end spindle 3 is driven by a driver through the peeling end rotor 4.

[0022] The fixed body 2 includes a fixed end spindle 6, one end of which is provided with a fixed end rotor 7, and the fixed end rotor 7 is provided with a needle 8 that cooperates with the needle pressure plate 5. The other end of the fixed end spindle 6 is also driven by a driver.

[0023] A cavity 9 is provided between the body 1 of the opening device and the body 2 of the fixing device.

[0024] This application uses a modifier (such as stearic acid) to form a monolayer coating on the surface of powder particles. Specifically, the working principle of the powder modification needle mill mainly relies on the needle structure to generate impact, shearing and friction on the material, while heat energy promotes the uniform coating of the modifier and the powder.

[0025] Furthermore, the equipment utilizes the friction between the high-speed rotating needle disc and the fixed needle seat to subject the powder material to strong impact and shear forces within the needle disc cavity, achieving deagglomeration and dispersion. The high-speed motion of the needle disc (typically reaching thousands of revolutions per minute) creates a vortex two-phase flow within the cavity, where the material and modifier are thoroughly mixed and undergo surface chemical reactions. During the modification process, the heat generated by friction raises the powder temperature, accelerating the chemical bonding between the modifier (such as stearic acid) and the powder surface. For example, a stearic acid monolayer can coat the surface of calcium carbonate particles while retaining a small amount of free modifier to enhance interparticle lubrication. Typical equipment employs a wide-cavity design and is equipped with an adjustable needle disc structure, optimizing the modification effect by changing conditions such as rotation speed and temperature. This structure ensures uniform force on the material and adapts to powder modification scenarios with different particle size requirements.

[0026] In this embodiment, the main shaft 3 at the opening end is fitted with a deep groove ball bearing 10, and the main shaft 3 at the opening end is also fitted with a bearing seat 11.

[0027] In this embodiment, the cavity 9 is provided with an injection cavity 12.

[0028] In this embodiment, the main body 1 of the opening device is also provided with a tensioning screw 13 for adjusting the tension of the belt. By rotating the screw, the motor is driven to move in and out, so as to adjust the tension of the belt.

[0029] In this embodiment, the main body 1 of the opening device is provided with a plurality of handwheels 14.

[0030] The above description is only a preferred embodiment of this application and is not intended to limit the scope of implementation of this application. Any other embodiments whose principles and basic structures are the same as or similar to those of this application are within the protection scope of this application.
