[0002] The components of iron are atoms such as iron, cobalt, nickel, etc. The internal structure of its atoms is relatively special and it has a magnetic moment itself. A magnet can generate a magnetic field and has the property of attracting ferromagnetic substances such as metals like iron, nickel, cobalt, etc.

[0003] When producing magnets, a grinding device is needed to grind the raw materials. However, when the raw materials are fed into the feeding port of the grinding device, under the action of gravity, the magnets will accumulate in one place, thus reducing the grinding efficiency of the grinding device. Usually, when the magnets are fed, they all contact one part of the grinding device, and long-term use will cause one part of the grinding device to be overused while the other part is not used. Content of the Utility Model

[0027] In order to enable those skilled in the art to better understand the present utility model, the technical solution of the present utility model will be further described below in conjunction with the drawings and embodiments.

[0028] As Figures 1-5 shown, a raw material grinding device for magnet production includes a grinding box 1. There is a feeding port 11 above the grinding box 1. Inside the grinding box 1, a transfer mechanism 2, a grinding mechanism 3, a filtering mechanism 4 and a material receiving part are arranged in sequence;

[0029] The transfer mechanism 2 includes a transfer plate 21 and a connecting member 22. The connecting member 22 is located below the transfer plate 21. The connecting member 22 is assembled and connected with a reciprocating transmission mechanism 23. The transfer plate 21 is located directly below the feeding port 11. Guide plates 24 inclined downward and outward are arranged on the left and right sides of the transfer plate 21. A plurality of vertical plates 25 are uniformly and fixedly connected above the transfer plate 21.

[0030] Adopting the technical solution of this embodiment, magnet raw materials enter the grinding box 1 from the feeding port 11. The transfer mechanism 2 is used to evenly transport the magnet raw materials, so that the magnet raw materials evenly fall above the grinding mechanism 3. The grinding mechanism 3 is used to grind the magnetic raw materials. The filtering mechanism 4 is used to screen the ground magnetic raw materials. The magnetic raw materials enter the grinding box 1 from the feeding port 11. The magnetic raw materials fall above the transfer plate 21. The transfer plate 21 drives the magnetic raw materials to move. Under the reciprocating movement of the transfer plate 21, the magnetic components fall. The guide plates 24 are used to separate the magnetic components.

[0031] Refer to Figure 1 and 4 : The reciprocating transmission mechanism 23 includes a reciprocating lead screw 231. The other end of the reciprocating lead screw 231 is rotatably connected to a slide bar 232. The number of connecting members 22 is two. One connecting member 22 is slidably connected to the slide bar 232, and the other connecting member 22 is threadedly connected to the reciprocating lead screw 231. A first motor 233 is fixedly connected to the end of the reciprocating lead screw 231.

[0032] In this embodiment, the first motor 233 drives the reciprocating lead screw 231 to rotate. The connecting member 22 is threadedly connected to the reciprocating lead screw 231. When the reciprocating lead screw 231 rotates, it drives the connecting member 22 to move, and the connecting member 22 drives the transfer plate 21 to move reciprocally. The function of the reciprocating lead screw 231 can also be achieved by the mutual cooperation of a telescopic cylinder, an electric lead screw, gears, and a rack.

[0033] Refer to Figures 1-2 : The grinding mechanism 3 includes a primary grinding assembly and a secondary grinding assembly. The primary grinding assembly includes two first grinding rollers 311. The two first grinding rollers 311 mesh with each other and rotate towards each other inward. One of the first grinding rollers 311 is drivingly connected to a second motor 312.

[0034] In this embodiment, the grinding mechanism 3 is used to grind the magnet raw material. The primary grinding assembly 31 is used to perform primary grinding on the magnetic raw material, and the secondary grinding assembly 32 is used to perform finer grinding on the magnetic raw material. The magnetic raw material that falls onto the upper side of the first grinding rollers 311 after passing through the transfer plate 21 is located on both sides of the grinding rollers 311. The first grinding rollers 311 rotate towards each other inward, driving the magnetic raw material to move towards the middle.

[0035] Refer to Figures 1-2 : The secondary grinding assembly includes four second grinding rollers 321. The four second grinding rollers 321 are divided into two groups. The two second grinding rollers 321 in one group are located on the same side. The two second grinding rollers 321 in one group mesh with each other and rotate towards each other inward. The two second grinding rollers 321 located in the middle rotate relatively outward. The end of one second grinding roller 321 is drivingly connected to a third motor 322.

[0036] In this embodiment, the size of the second grinding rollers 321 is smaller than that of the first grinding rollers 311. The magnetic raw material that falls from the second grinding rollers 321 lands in the middle of the two second grinding rollers 321 in the middle. When the two second grinding rollers 321 in the middle rotate outward, they drive the magnetic raw material to move towards both sides, and the second grinding rollers 321 on the left and right sides grind the magnetic raw material.

[0037] Refer to Figures 1-2 : The filtering mechanism 4 includes a filter screen plate 41. The filter screen plate 41 is slidably connected to the grinding box 1. An elastic member 42 is slidably connected to the lower side of the filter screen plate 41. A vibration motor 43 is assembled and connected to the edge of the filter screen plate 41.

[0038] In this embodiment, the filter screen plate 41 filters and screens the ground magnetic raw material. The vibration motor 43 is used to vibrate the filter screen plate 41 up and down, and the elastic member 42 is used to reduce the impact force received by the filter screen plate 41 during vibration.

[0039] Refer to Figure 3 : The material receiving part is a material receiving frame 51, and the grinding box 1 is provided with an outlet for the material receiving frame 51.

[0040] In this embodiment, the material receiving frame 51 is used to collect the filtered magnetic raw materials, and the material receiving frame 51 is taken out from the outlet of the material receiving frame 51.

[0041] The control mode of the present utility model is automatically controlled by a controller. The control circuit of the controller can be realized by simple programming of those skilled in the art. The provision of power also belongs to the common knowledge in this field. And the present utility model is mainly used to protect mechanical devices. Therefore, the control mode and circuit connection of the present utility model will not be further explained in detail.

[0042] The above embodiments are only used to exemplarily illustrate the principles and effects of the present utility model, rather than to limit the present utility model. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present utility model. Therefore, all equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the present utility model should still be covered by the claims of the present utility model.
