[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0032] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0033] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-5 A high-efficiency sintering device for permanent magnet ferrite materials includes a base 1, a reciprocating swing mechanism 2, an auxiliary box opening mechanism 3, and a sintering box 4; the base 1 is equipped with a reciprocating swing mechanism 2 for controlling the movement of the sintering box 4; the top of the sintering box 4 is hinged with a cover that can be flipped.

[0034] The reciprocating swing mechanism 2 includes a drive assembly 21 for controlling the swing of the bearing support assembly 22 and a bearing support assembly 22 for driving the sintering box 4 to move; the drive assembly 21 is installed at the inner bottom of the base 1, the bearing support assembly 22 is installed at the top of the base 1, and the drive assembly 21 is connected to the bearing support assembly 22.

[0035] An auxiliary opening mechanism 3 for controlling the automatic opening and closing of the sintering box 4 cover is installed on the support assembly 22. The auxiliary opening mechanism 3 includes a movable component 31 for controlling the movement of the sintering box 4 for loading and unloading operations, an opening and closing component 32 for controlling the opening and closing of the sintering box 4 cover, and a mounting frame 33. The mounting frame 33 is installed on the support assembly 22, the movable component 31 is installed inside the mounting frame 33, the sintering box 4 is installed on the movable component 31 and connected to the opening and closing component 32, and the opening and closing component 32 is installed on the mounting frame 33 and connected to the cover of the sintering box 4.

[0036] The left side of the mounting frame 33 is set as the loading and unloading station; the middle part of the mounting frame 33 is set as the sintering station.

[0037] In this invention, when the sintering box 4 is in the loading / unloading position, the cover on the top of the sintering box 4 is opened upwards under the action of the opening and closing component 32. Then, the operator places the permanent magnet ferrite raw material to be sintered into the sintering box 4 in the loading / unloading position. Then, the movable component 31 works to move the sintering box 4 toward the sintering position. During the movement, the opening and closing component 32 works to make the cover on the sintering box 4 rotate downwards until the cover is in a horizontal position, thereby closing the opening at the top of the sintering box 4. Then, the sintering box 4 works to heat and sinter the permanent magnet ferrite raw material inside.

[0038] During the operation of the sintering box 4, the drive component 21 drives the bearing support component 22 to swing back and forth. The mounting frame 33 moves together with the bearing support component 22, causing the sintering box 4 to swing back and forth and continuously turning over all the permanent magnet ferrite raw materials in the sintering box 4. This improves the uniformity of heating of the permanent magnet ferrite raw materials during the sintering process and also avoids the agglomeration of the permanent magnet ferrite raw materials during the sintering process, thereby improving the sintering quality.

[0039] This invention, through the cooperation of the movable component 31 and the opening and closing component 32, enables the cover on the sintering box 4 to open and close automatically after sintering is completed and at the start of sintering, avoiding burns when manually opening the cover and further improving the practicality of the device.

[0040] like Figures 1-4As shown, the drive assembly 21 includes a drive motor 211, a T-type reducer 212, a rotating shaft 213, a vertical plate 214, a drive gear 215, a driven gear ring 216, a guide wheel 217, and an arc-shaped plate 218. The drive motor 211 is fixedly installed on the front side of the inner bottom of the base 1; the T-type reducer 212 is fixedly installed in the middle of the inner bottom of the base 1; the output end of the drive motor 211 is fixedly connected to the input end of the T-type reducer 212; the output ends on both sides of the T-type reducer 212 are fixedly connected to one end of the rotating shaft 213; two vertical plates 214 are symmetrically fixedly installed on the left and right sides of the inner bottom of the base 1; the drive gear 215 is rotatably installed on the bottom outer end of the vertical plate 214; the other end of the rotating shaft 213 is rotatably connected to the bottom inner end of the vertical plate 214; and the rotating shaft 213 passes through the vertical plate 214 and is fixedly connected to the drive gear 215.

[0041] Two arc-shaped plates 218 are respectively installed on the left and right sides of the support assembly 22; a driven gear ring 216 is fixedly installed at the bottom of the arc-shaped plate 218; the driven gear ring 216 is meshed with the drive gear 215. A guide wheel 217 is rotatably installed on the top of the outer end of the vertical plate 214; the arc-shaped plate 218 is located between the driven gear ring 216 and the guide wheel 217, and the guide wheel 217 is in rolling connection with the top surface of the arc-shaped plate 218.

[0042] like Figures 1-4 As shown, the supporting assembly 22 includes a swing disk 221, connecting rods 222, rollers 223, and mounting brackets 224. Multiple mounting brackets 224 are fixedly installed at the four corners of the top of the base 1. Rollers 223 are rotatably mounted on the mounting brackets 224. Each roller 223 has a sliding groove. Two swing disks 221 are respectively located on the left and right sides of the top of the base 1, and the bottom sides of the swing disks 221 are slidably connected to the two rollers 223 on the same side, with the bottom of the swing disks 221 also rollingly connected to the sliding grooves on the two rollers 223 on the same side. Two connecting rods 222 are symmetrically fixed between the left and right swing disks 221. A mounting frame 33 is fixedly installed on the left and right swing disks 221. An arc-shaped plate 218 is fixedly installed inside the swing disks 221. The mounting frame 33 is located between the two connecting rods 222 and is fixedly installed on the two swing disks 221.

[0043] like Figures 1-4 As shown, the movable component 31 includes a push cylinder 311, guide rails 312, and sliding blocks 313. The push cylinder 311 is fixedly installed at the front end of the mounting frame 33. The two guide rails 312 are symmetrically fixedly installed on the front and rear sides of the inner side of the mounting frame 33. The two sliding blocks 313 are respectively limited and slidably connected to the two guide rails 312. The front and rear sides of the bottom of the sintering box 4 are respectively fixedly connected to the two sliding blocks 313. The output end of the push cylinder 311 is fixedly connected to the left side of the sintering box 4.

[0044] like Figures 1-4 As shown, the opening and closing assembly 32 includes a first rotating rod 321 and a second rotating rod 322. One end of the first rotating rod 321 is fixedly connected to the left side of the top cover of the sintering box 4; the other end of the first rotating rod 321 is hinged to one end of the second rotating rod 322; and the other end of the second rotating rod 322 is hinged to the upper left side of the mounting frame 33.

[0045] In this invention, the operator places the permanent magnet ferrite raw material into the sintering box 4 located at the loading and unloading station. Then, the push cylinder 311 works to pull the sintering box 4 along the guide rail 312, following the sliding block 313, towards the sintering station. During the movement of the sintering box 4, the cover will move to the right, at which point the cover will pull the first rotating rod 321 downwards. The first rotating rod 321 pulls the second rotating rod 322 downwards, until the cover is horizontal and closes the top opening of the sintering box 4. At this point, the sintering box 4 is closed and in the sintering station. Subsequently, the sintering box 4 operates to heat and sinter the permanent magnet ferrite raw material inside.

[0046] During the sintering process, the drive motor 211 drives the T-type reducer 212 to work. The T-type reducer 212 causes the rotating shafts 213 on both sides to rotate. The rotation of the rotating shafts 213 drives the drive gear 215 to rotate. The drive gear 215 then drives the driven gear ring 216 to drive the arc plate 218 to rotate along the guide wheel 217. At this time, the swing disk 221 follows the arc plate 218 to swing back and forth along the support roller 223. The mounting frame 33 swings back and forth along with the swing disk 221, which continuously turns over the permanent magnet ferrite raw materials in the sintering box 4, so that all the permanent magnet ferrites can be heated evenly.

[0047] After sintering is completed, the drive motor 211 stops working, and the positions of the swing disk 221 and the mounting frame 33 are restored. The push cylinder 311 works to push the sintering box 4 to move horizontally to the left. During the movement, the first rotating rod 321 pulls the cover set on the sintering box 4 to rotate upward. The upward rotation of the first rotating rod 321 will lift the second rotating rod 322 upward until the sintering box 4 moves to the loading and unloading station. At this time, the cover set on the sintering box 4 will be flipped open upward under the traction of the first rotating rod 321 and the second rotating rod 322. Then, wait for the permanent magnet ferrite material to cool down after sintering.

[0048] Example 2: In some embodiments, such as Figure 5As shown, in a preferred embodiment of this utility model, a baffle is fixedly installed on the outer side of the second rotating rod 322. When the sintering box 4 moves to the right to the sintering station, the sintering box 4 drives the second rotating rod 322 to rotate downward, and the second rotating rod 322 drives the baffle to rotate downward, so that the baffle moves to the left end opening of the mounting frame 33, reducing the size of the left end opening of the mounting frame 33 and reducing the heat dissipation during sintering in the sintering box 4.

[0049] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
