Description

Technical Field

[0001] This utility model relates to the field of magnet raw material proportioning technology, and in particular to a neodymium iron boron magnet raw material proportioning and mixing device. Background Technology

[0002] In the manufacturing process of neodymium iron boron magnets, high-purity neodymium, iron, and boron powders need to be proportioned first, then placed in a mixing device for thorough mixing, and finally pressed into magnet shapes for magnetization. However, currently, the proportioning and mixing steps are performed separately, which increases the number of processing steps and affects the production efficiency of magnets. Furthermore, the existing mixing method uses a spiral mixer, which, due to the use of only one spiral auger for stirring and mixing, makes it difficult to mix materials adhering to the side wall of the barrel. Therefore, to solve the above problems, a neodymium iron boron magnet raw material proportioning and mixing device was designed. Utility Model Content

[0003] In view of the shortcomings of existing magnet raw material proportioning, the purpose of this utility model is to provide a neodymium iron boron magnet raw material proportioning and mixing device, which has the advantages of simultaneously performing material proportioning and mixing and thorough mixing.

[0004] To achieve the above objectives, the present invention employs the following technical solution: a neodymium iron boron magnet raw material proportioning and mixing device, comprising a raw material barrel, a mixing barrel, a combined mixing plate, a proportioning control component, a multi-functional auger, a drive component, a discharge mechanism, and a control panel. The mixing barrel has three raw material barrels connected to its top, which slide axially along the top of the mixing barrel. A proportioning control component for controlling the proportion of raw materials is located inside the raw material barrel. A combined mixing plate is located inside the mixing barrel at the corresponding material drop position, used for preliminary mixing of the raw materials entering the mixing barrel. A multi-functional auger for mixing raw materials is rotatably connected to the middle of the mixing barrel. The drive component is located inside the mixing barrel for driving the multi-functional auger to rotate. A discharge mechanism is located at the discharge port of the mixing barrel. A control panel for operation is located on the outer wall of the mixing barrel.

[0005] Preferably, the combined mixing plate has a V-shaped plate and a sloping plate. The V-shaped plate is disposed upside down at the bottom outlet of the middle raw material barrel, and the sloping plates are disposed at the bottom outlets of the two side raw material barrels respectively. One end of the sloping plate extends to the bottom of the V-shaped plate.

[0006] Preferably, the proportional control component includes a telescopic rod, a sealing plate, and a weight sensor. The weight sensor is fixedly connected to the outer wall of the raw material barrel via a bracket and is used to measure the overall mass of the raw material barrel. The telescopic rod is located at the top of the raw material barrel, and its telescopic end extends into the discharge port of the raw material barrel. The telescopic end of the telescopic rod is fixedly connected to the sealing plate, and the sealing plate slides axially within the discharge port of the raw material barrel. The sealing plate is used to control the opening or closing of the discharge port of the raw material barrel.

[0007] Preferably, the multifunctional auger has an annular mounting ring, a spiral auger, a toothed ring, and scrapers. The annular mounting ring is rotatably connected inside the mixing tank. The spiral auger is fixedly connected to the middle of the annular mounting ring by a bracket. Two scrapers that fit against the inner wall of the mixing tank are symmetrically provided at the bottom of the annular mounting ring. A toothed ring is provided on the inner circle of the annular mounting ring.

[0008] Preferably, the drive assembly includes a drive motor and a drive gear, the drive gear meshes with a gear ring, the drive gear is fixedly connected to the output shaft of the drive motor, and the drive motor is fixedly connected inside the mixing tank;

[0009] Preferably, the discharge mechanism includes a hydraulic rod and a baffle. The baffle is hinged to one side of the discharge port of the mixing tank. The bottom of the hydraulic rod is hinged to the mixing tank. The telescopic end of the hydraulic rod is hinged to one side of the baffle. The hydraulic rod is used to drive the baffle to block or open the discharge port of the mixing tank.

[0010] The beneficial effects of this utility model are: 1. By recording the weight of the raw materials by a weight sensor outside the raw material barrel, the weight sensor calculates the difference in weight between the three raw material barrels when making the proportion, thereby accurately controlling the proportion of raw materials; 2. The raw materials in the mixing barrel are fully mixed by a spiral auger. At the same time as the spiral auger mixes, the scraper plate is attached to the inner wall of the mixing barrel, so that the raw materials adhering to the inner wall of the mixing barrel can also be scraped off and mixed.

[0019] The combined mixing plate 3 has a V-shaped plate 31 and an inclined plate 32. The V-shaped plate 31 is set up in an upside-down manner at the bottom outlet of the middle raw material barrel 1. The inclined plate 32 is set at the bottom outlet of the two side raw material barrels 1 respectively. One end of the inclined plate 32 extends to the bottom of the V-shaped plate 31.

[0020] The proportional control component 4 has a telescopic rod 41, a sealing plate 42, and a weight sensor 43. The weight sensor 43 is fixedly connected to the outer wall of the raw material barrel 1 by a bracket. The weight sensor 43 is used to measure the overall mass of the raw material barrel 1. The telescopic rod 41 is set at the top of the raw material barrel 1. The telescopic end of the telescopic rod 41 extends into the discharge port of the raw material barrel 1. The telescopic end of the telescopic rod 41 is fixedly connected to the sealing plate 42. The sealing plate 42 slides axially in the discharge port of the raw material barrel 1. The sealing plate 42 is used to control the opening or closing of the discharge port of the raw material barrel 1.

[0021] The multi-functional auger 5 has an annular mounting ring 51, a spiral auger 52, a toothed ring 53, and a scraper 54. The annular mounting ring 51 is rotatably connected to the inside of the mixing tank 2. The spiral auger 52 is fixedly connected to the middle of the annular mounting ring 51 by a bracket. Two scraper 54s that fit against the inner wall of the mixing tank 2 are symmetrically provided at the bottom end of the annular mounting ring 51. A toothed ring 53 is provided on the inner circle of the annular mounting ring 51.

[0022] The drive assembly 6 includes a drive motor 61 and a drive gear 62. The drive gear 62 meshes with a gear ring 53. The drive gear 62 is fixedly connected to the output shaft of the drive motor 61. The drive motor 61 is fixedly connected inside the mixing tank 2.

[0023] The discharge mechanism 7 includes a hydraulic rod 71 and a baffle 72. The baffle 72 is hinged to one side of the discharge port of the mixing tank 2. The bottom of the hydraulic rod 71 is hinged to the mixing tank 2. The telescopic end of the hydraulic rod 71 is hinged to one side of the baffle 72. The hydraulic rod 71 is used to drive the baffle 72 to block or open the discharge port of the mixing tank 2.

[0024] With the above settings, its specific working principle in actual operation is as follows:

[0025] Before mixing, neodymium, iron, and boron powders are first loaded into three raw material containers 1 respectively, and then the data to be mixed is entered into the control panel 8.

[0026] During the mixing process, the weight sensors 43 on the outside of the three raw material barrels 1 record the initial weight of the raw materials. Then, the control panel 8 activates the telescopic rods 41 inside the three raw material barrels 1 respectively, so that the telescopic rods 41 drive the sealing plate 42 to open the discharge port of the raw material barrel 1, thereby causing the raw materials in the raw material barrel 1 to fall into the mixing barrel 2. During this process, the weight sensor 43 calculates the difference in weight of the three raw material barrels 1, so as to accurately control the mixing ratio of the raw materials.

[0027] While the mixing process is underway, the raw materials falling from the raw material barrel 1 come into contact with the V-shaped plate 31 and the inclined plate 32, thereby mixing the raw materials in pairs before they fall into the mixing barrel 2.

[0028] While the mixing ratio is being carried out, the drive motor 61 is also started at the same time. The drive motor 61 drives the multi-functional auger 5 to rotate through the drive gear 62 and the gear ring 53. During the rotation of the multi-functional auger 5, the spiral auger 52 fully mixes the raw materials in the mixing barrel 2. At the same time as the spiral auger 52 mixes, the scraper 54 is attached to the inner wall of the mixing barrel 2, so that the raw materials adsorbed on the inner wall of the mixing barrel 2 can also be scraped off and mixed.

[0029] After mixing is completed, the hydraulic rod 71 is extended, and the hydraulic rod 71 drives the baffle 72 to open the discharge port of the mixing tank 2, thereby unloading the material;
