[0002] Magnetic materials refer to materials that can directly or indirectly generate magnetism from transition elements such as iron, cobalt, nickel and their alloys. Magnetic materials can be divided into soft magnetic materials and hard magnetic materials according to the difficulty of demagnetization after magnetization. Materials that are easy to demagnetize after magnetization are called soft magnetic materials, and materials that are not easy to demagnetize are called hard magnetic materials. Magnetic materials are made through powder making - mixing - molding - sintering - finishing - magnetization. During molding, a granulator is generally used for continuous granulation. However, when the roller extrude the powder, the internal pressure groove is easy to adhere to the material, resulting in a reduction in the number of pressure grooves and reducing the efficiency of granulation.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] The utility model provides a high-efficiency magnetic material continuous granulation device, such as Figure 1-2 As shown, it includes a shell 1 with a conical feed hopper 2 on the top, two parallel pressing rollers 3 with pressing grooves on the outer walls are rotatably connected in the shell 1, and the pressing grooves are used for granulating magnetic materials. A motor for driving one of the pressing rollers 3 to rotate is installed on the outer wall of the shell 1, and a meshing gear 4 is connected to the same end of the two pressing rollers 3. A crushing roller 5 for breaking block magnetic materials is provided below the pressing roller 3. The crushing roller 5 is connected to the pressing roller 3 through a belt drive, and a screen 10 for screening the formed magnetic materials is provided below the crushing roller 5. A through hole for recycling materials is provided at the bottom of the shell 1, and a material port for discharging the formed magnetic materials is provided at the side wall of the shell 1 and at the bottom end of the screen 10. A slot cleaning component 6 for cleaning the pressing groove is connected to the inner wall of the shell 1, and the position of the slot cleaning component 6 is as shown in FIG. Figure 1 As shown, the magnetic material powder enters the housing 1 through the feed hopper 2, and the motor drives the pressing roller 3 to rotate, so that the powder passing through the middle of the two pressing rollers 3 can be extruded and formed. After extrusion, the magnetic material powder has the same shape as the pressing groove, and is connected with flake powder. It continues to fall and is crushed by the crushing roller 5, so that the soft flake powder can be crushed. The formed magnetic material falls and is discharged from the top of the screen 10, and the unformed magnetic material is recovered and reshaped through the screen 10.

[0022] The slot cleaning assembly 6 includes a fixed seat 61 installed on the inner wall of the housing 1, a spring 63 is connected to the side wall of the fixed seat 61, and a fixed tube 62 is connected to the end of the spring 63. The spring 63 connects the fixed tube 62 to the fixed seat 61, which can increase the swing amplitude of the fixed tube 62 when it is vibrated. A metal wire 64 that contacts the pressure roller 3 is installed on the side wall of the fixed tube 62. The metal wire 64 is located in the movement path of the pressure groove and can contact the pressure groove when the pressure roller 3 rotates. A fixed tube 65 is fixed to the side wall of the fixed tube 62, and an end is inserted into the fixed tube 65. The resistance rod 66 that resists the gear 4 can, through the metal wire 64 of the groove cleaning component 6, resist the grooves on the surface of the pressing roller 3 to clean them when the pressing roller 3 rotates, to prevent the magnetic material from adhering to the grooves and causing a reduction in the number of grooves that can be extruded, and to reduce the number of available grooves when the pressing roller 3 rotates once, thereby ensuring efficient and continuous granulation efficiency. The resistance rod 66 that resists the gear 4 can continuously vibrate when the gear 4 rotates and transmit it to the fixed tube 62, driving the metal wire 64 to vibrate, which is beneficial to improving the cleaning effect of the material adhering to the grooves.

[0023] Specifically, the slot cleaning component 6 also includes a fan 8 installed on the top of the shell 1. The fan 8 has a switch button. The air outlet of the fan 8 is connected to the air duct 7. The other end of the air duct 7 extends into the shell 1 and is connected to the fixed tube 62. The side wall of the fixed tube 62 is provided with an air hole 9 facing the pressure roller 3. The fan 8 guides the forced airflow through the air duct 7 to the fixed tube 62 and sprays it out from the air hole 9, which can exert an airflow impact on the material in the pressure slot, thereby improving the cleaning effect of the pressure slot.

[0024] Specifically, the number and positions of the air holes 9 correspond to the pressed grooves.

[0025] Specifically, the fixing tube 62 is a hollow tubular structure.

[0026] Specifically, a screw threadedly connected to the side wall of the fixing tube 65 is passed through, and the end of the screw can contact the abutment rod 66 to limit its movement, thereby facilitating the adjustment of the distance between the abutment rod 66 and the gear 4 and ensuring the optimal distance for the gear 4 to impact the abutment rod 66 when rotating.

[0027] Specifically, one end of the abutment rod 66 close to the gear 4 is hemispherical, so as to ensure smooth collision between the abutment rod 66 and the gear 4 .

[0028] Working principle: When in use, the powder of magnetic material enters the shell 1 through the feed hopper 2, and the motor drives the pressing roller 3 to rotate, and the powder passing through the middle of the two pressing rollers 3 can be extruded and formed. After extrusion, the magnetic material powder is in the same shape as the pressing groove, and is connected with flaky powder. It continues to fall and is crushed by the crushing roller 5, and the softer flaky powder can be crushed. The formed magnetic material falls and is discharged from the top of the screen 10. The unformed magnetic material is recovered and reshaped through the screen 10. When the pressing roller 3 rotates, the metal wire 64 of the slot cleaning component 6 can contact the pressing groove on its surface for cleaning, so as to prevent the magnetic material from adhering to the pressing groove and reducing the number of pressing grooves that can be extruded and formed, and reduce the number of pressing grooves available when the pressing roller 3 rotates once, thereby ensuring efficient and continuous granulation efficiency. The contact rod 66 that contacts the gear 4 can continuously vibrate and transmit to the fixed pipe 62 when the gear 4 rotates, driving the metal wire 64 to vibrate, which is beneficial to improving the cleaning effect of the material adhering to the pressing groove.
