Description

Technical Field

[0001] This utility model belongs to the field of magnetic powder pressing and processing technology, specifically relating to a material cylinder for preventing agglomeration of powdered magnetic powder materials. Background Technology

[0002] The existing material cylinders on the market are all of general structure and are simply used as material carriers. They do not take into account the changes in materials over time and in the environment, and cannot adapt to increasingly sophisticated industrial production, especially for environmentally sensitive materials such as neodymium iron boron.

[0003] The raw materials for pressing NdFeB metals are pre-loaded into the powder press's cylinder before startup and then transported to the pressing area via rubber pipes. Because the raw materials are generally composed of very fine metal powder, and NdFeB materials, in particular, have strong water absorption and oxidizing properties, they easily absorb moisture from the air during prolonged operation, causing powder agglomeration and reduced flowability. This reduced flowability can lead to: (1) Material blockage in rubber conveying pipeline results in material not being filled, compressor running out of power, damaging molds and equipment; (2) The uneven filling of materials in the mold cavity leads to a decrease in the consistency of product size and performance; (3) Water absorption causes electrochemical reactions in NdFeB materials, resulting in reduced performance. Utility Model Content

[0004] To address the aforementioned issues, this invention provides an anti-agglomeration feeder for powdered magnetic powder materials. It is particularly suitable for solving the problem of powder agglomeration caused by the absorption of moisture from the air during storage in the feeder for environmentally sensitive materials such as neodymium iron boron materials during production, thereby maintaining the stability of the material properties.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A powdered magnetic powder material anti-agglomeration cylinder includes a cylinder body, a cylinder cover, and a stirring blade fixing frame, stirring blades, stirring blade support columns, and thermocouples disposed inside the cylinder body. An isolation inner cylinder structure is also provided inside the cylinder body. The stirring blade fixing frame is located at the upper end of the isolation inner cylinder structure, the stirring blades are located below the stirring blade fixing frame, and the stirring blade support columns are located below the stirring blades. A motor positioning rod is also provided on the stirring blade fixing frame, extending out of the cylinder body. A servo motor is provided at the outer end of the motor positioning rod, and the servo motor controls the rotation of the stirring blades.

[0006] Furthermore, the barrel body includes a cylindrical section and a conical section, with a discharge port located at the bottom of the conical section. The included angle of the conical section of the barrel body is 32-35°.

[0007] Furthermore, the insulating inner cylinder structure includes an upper annular end face and a lower inner liner. The upper annular end face is sealed to the cylindrical section of the barrel body, and the lower inner liner is sealed to the conical section of the barrel body. The thermocouple is mounted on the insulating inner cylinder structure and located within the sealed space between the insulating inner cylinder structure and the barrel body. Two thermocouples are symmetrically arranged on both sides of the insulating inner cylinder structure.

[0008] Furthermore, the stirring blade includes a rotating shaft and a blade body mounted on the rotating shaft. The rotating shaft is mounted on the stirring blade holder via bearings. A transmission belt is provided inside the motor positioning rod to transmit the power of the servo motor to the rotating shaft, thereby driving the stirring blade to rotate.

[0009] Furthermore, the stirring blade support column includes a cross-shaped base and a support column body disposed on the cross-shaped base. The upper end of the support column body is a protruding hemispherical structure design. The cross-shaped base is fixedly snapped into the lower end of the conical section of the material cylinder body. The upper end of the support column body is correspondingly disposed with the lower end of the rotating shaft of the stirring blade.

[0010] Furthermore, the lower end of the rotating shaft of the stirring blade is designed with a concave hemispherical structure, which corresponds to the upper end of the support column body.

[0011] Furthermore, the barrel cover is detachably disposed on the outer side of the upper end of the cylindrical section of the barrel body, and a dustproof cotton is also disposed between the barrel cover and the barrel body, the dustproof cotton being detachably disposed on the barrel cover.

[0012] Furthermore, a barrel fixing strap is provided on the outer side of the cylindrical section of the barrel body to fix the barrel to the powder press.

[0013] This invention modifies the material cylinder by adding spirally rising stirring blades and a thermocouple, and by incorporating dustproof cotton to improve the original metal cylinder cover. The rotating blades cause materials such as neodymium iron boron to tumble within the cylinder, and the thermocouple's heating action evaporates moisture, keeping the powder dry and preventing agglomeration. The dustproof cotton at the top effectively prevents dust from overflowing during stirring, thus avoiding environmental pollution and harm to workers' health. It also allows moisture inside the cylinder to evaporate and prevents external impurities from entering. Attached Figure Description

[0017] like Figure 4As shown, the barrel body 1 includes a cylindrical section 11 and a conical section 12, with a discharge port 10 located below the conical section 12. The included angle of the conical section 12 of the barrel body 1 is 32-35°, facilitating material discharge. The insulating inner cylinder structure 7 includes an upper annular end face 71 and a lower inner liner 72. The upper annular end face 71 is sealed to the cylindrical section 11 of the barrel body 1, and the lower inner liner 72 is sealed to the conical section 12 of the barrel body 1. The thermocouple 6 is mounted on the insulating inner cylinder structure 7 and located within the sealed space between the insulating inner cylinder structure 7 and the barrel body 1.

[0018] The present invention describes two thermocouples 6, which are symmetrically arranged on both sides of the isolation inner cylinder structure 7.

[0019] like Figure 5 As shown, the stirring blade 4 includes a rotating shaft 41 and a blade body 42 disposed on the rotating shaft 41. The rotating shaft 41 is disposed on the stirring blade fixing frame 3 through a bearing structure. A transmission belt (not shown in the relevant structural diagram) is disposed inside the motor positioning rod 8 to transmit the power of the servo motor 9 to the rotating shaft 41, thereby driving the stirring blade 4 to rotate.

[0020] like Figure 6 As shown, the stirring blade support column 5 includes a cross-shaped base 51 and a support column body 52 disposed on the cross-shaped base 51. The upper end of the support column body 52 is a protruding hemispherical structure design. The cross-shaped base 51 is fixedly snapped into the lower end of the conical section 12 of the material cylinder body 1. The upper end of the support column body 52 is correspondingly disposed to the lower end of the rotating shaft 41 of the stirring blade 4.

[0021] The lower end of the rotating shaft 41 of the stirring blade 4 has a concave hemispherical structure design, which corresponds to the upper end of the support column body 52. ​​The stirring blade fixing frame 3 at the upper part of the stirring blade 4 and the stirring blade support column 5 at the lower part cooperate to enable the stirring blade 4 to rotate stably.

[0022] The structure of the barrel cover 2 is as follows Figure 7 As shown, the barrel cover 2 is detachably mounted on the outer side of the upper end of the cylindrical section 11 of the barrel body 1.
