[0015] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0016] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0017] like Figures 1-5 As shown, a feeding mechanism for an air jet mill for lithium iron phosphate includes: an air jet mill 1, a controller 101 installed on one side of the air jet mill 1, a feed frame 102 installed on the top of the air jet mill 1, a control plate 103 disposed inside the feed frame 102, a screening plate 104 installed at an incline inside the feed frame 102, a control component disposed inside the air jet mill 1 for controlling the amount of material entering the equipment, the control component including: the control plate 103, a ratchet 201 and a ratchet bar 301, and a screening component disposed inside the air jet mill 1 for crushing large particles of material and reducing the operating pressure of the equipment, the screening component including: the screening plate 104, an active crushing roller 502 and a driven crushing roller 6.

[0018] The material feed rate can be precisely controlled by the control plate 103, ratchet 201, and ratchet bar 301 in the control component. This prevents the material from being overloaded or underloaded, which would affect the grinding efficiency. It ensures that the equipment operates under a suitable load, ensuring continuous production and reasonable energy consumption. Secondly, the screening plate 104, active crushing roller 502, and driven crushing roller 6 can screen and crush large particles, reducing the amount of coarse material entering the air jet mill, reducing the grinding pressure and wear of the equipment, improving the uniformity of material grinding and the quality of finished products, and extending the service life of the equipment.

[0019] The feed frame 102 is rotatably connected to a rotating rod 2. One end of the rotating rod 2 passes through the control plate 103, and the outer side of the rotating rod 2 is connected to the inside of the control plate 103. A ratchet 201 is provided on the outer side of the feed frame 102. One side of the ratchet 201 is connected to one end of the rotating rod 2. A control wheel 3 is connected to one side of the ratchet 201. A ratchet bar 301, which is used in conjunction with the ratchet 201, is rotatably connected to one side of the feed frame 102 via a rotating shaft. A fixing plate 4 is connected to one side of the feed frame 102. An arc spring 401 is installed on the top of the fixing plate 4. One end of the arc spring 401 is connected to one side of the ratchet bar 301.

[0020] When the equipment is working, the operator adjusts the feed rate by rotating the control wheel 3. The control wheel 3 drives the ratchet 201 and the rotating rod 2 connected to the control wheel 3 to rotate synchronously. The rotation of the rotating rod 2 drives the control plate 103 to change its tilt angle inside the feed frame 102, thereby adjusting the size of the opening through which the material passes. When the angle is adjusted to the correct position, under the elastic force of the arc spring 401, the end of the ratchet bar 301 automatically engages with the teeth of the ratchet 201, utilizing the one-way self-locking characteristic of the ratchet mechanism to lock the rotating rod 2. The control plate 103 is firmly locked in its current position to prevent angle changes due to vibration, thereby achieving stable feeding. When it is necessary to remove the ratchet bar 301 from the ratchet wheel 201, move the other end of the ratchet bar 301 to disengage the end of the ratchet bar 301 from the ratchet wheel 201. Then, rotate the ratchet wheel 201 to reset it. After adjustment, release the ratchet bar 301. The elastic force of the arc spring 401 pushes the ratchet bar 301 to reset it, and the end of the ratchet bar 301 is engaged in the teeth of the ratchet wheel 201.

[0021] The feed frame 102 is internally connected to a vertical plate 5. The top of the vertical plate 5 is connected to the bottom of the screening plate 104. One side of the vertical plate 5 is rotatably connected to the inner wall of the feed frame 102 with an active crushing roller 502 and a driven crushing roller 6. A motor 501 is installed on one side of the feed frame 102. One side of the motor 501 is driven by a drive shaft connected to one end of the active crushing roller 502. A gear a503 is provided on one side of the feed frame 102. One side of the gear a503 is connected to the other end of the active crushing roller 502. A gear b601 is meshed with one side of the gear a503. One side of the gear a503 is connected to one end of the driven crushing roller 6. A sprocket a7 is connected to one side of the gear a503. A sprocket b701 is provided on one side of the feed frame 102. A chain 702 is provided between the sprocket a7 and the sprocket b701. A fixing rod 703 is connected to one side of the sprocket b701. One end of the fixing rod 703 extends into the inside of the feed frame 102 and is connected to an impact wheel 704. A rubber block 705 is installed at the bottom of the screening plate 104. One end of the impact wheel 704 is in contact with the rubber block 705. One end of the fixing rod 703 is rotatably connected to the inner wall of the feed frame 102 through a bearing.

[0022] Furthermore, after feeding, the material first falls onto the inclined screening plate 104 for preliminary screening. Fine particles that meet the particle size requirements pass directly through, while larger particles slide down the surface of the screening plate to the crushing area between the active crushing roller 502 and the driven crushing roller 6. At the same time, the motor 501 drives the active crushing roller 502 to rotate, and through the meshing transmission of gear a503 and gear b601, it drives the driven crushing roller 6 to rotate synchronously in the opposite direction, effectively crushing large particles. Meanwhile, gear a503 drives the fixed rod 703 and the impact wheel 704 to rotate continuously through the transmission of sprocket a7, chain 702 and sprocket b701. The rotating impact wheel 704 periodically impacts the rubber block 705 at the bottom of the screening plate 104, causing the screening plate 104 to produce slight continuous vibration, improving screening efficiency and preventing screen hole clogging.

[0023] Working principle: When the equipment is working, the operator adjusts the feed rate by rotating the control wheel 3. The control wheel 3 drives the ratchet 201 and the rotating rod 2 connected to the control wheel 3 to rotate synchronously. The rotation of the rotating rod 2 drives the control plate 103 to change its tilt angle inside the feed frame 102, thereby adjusting the size of the opening through which the material passes. When the angle is adjusted to the correct position, under the elastic force of the arc spring 401, the end of the ratchet bar 301 will automatically engage with the teeth of the ratchet 201. The one-way self-locking characteristic of the ratchet mechanism firmly locks the rotating rod 2 and the control plate 103 in the current position, preventing the angle from changing due to vibration, thereby achieving stable feeding.

[0024] Furthermore, when it is necessary to release the ratchet bar 301 from the ratchet wheel 201, move the other end of the ratchet bar 301 to disengage the end of the ratchet bar 301 from the ratchet wheel 201. Then, rotate the ratchet wheel 201 to reset it. After adjustment, release the ratchet bar 301. The elastic force of the arc spring 401 pushes the ratchet bar 301 to reset it, and the end of the ratchet bar 301 is engaged in the teeth of the ratchet wheel 201.

[0025] Furthermore, after feeding, the material first falls onto the inclined screening plate 104 for preliminary screening. Fine particles that meet the particle size requirements pass directly through, while larger particles slide down the surface of the screening plate into the crushing area between the active crushing roller 502 and the driven crushing roller 6. At the same time, the motor 501 drives the active crushing roller 502 to rotate, and through the meshing transmission of gear a503 and gear b601, it drives the driven crushing roller 6 to rotate synchronously in the opposite direction, effectively crushing the large particles.

[0026] Furthermore, gear a503 drives the fixed rod 703 and the impact wheel 704 to rotate continuously through the transmission of sprocket a7, chain 702 and sprocket b701. The rotating impact wheel 704 periodically impacts the rubber block 705 at the bottom of the screening plate 104, causing the screening plate 104 to vibrate slightly and continuously, improving screening efficiency and preventing screen hole clogging.

[0027] In addition, all electrical components mentioned in the article are electrically connected to the main controller and power supply. The main controller can be a conventional known device such as a computer that performs control, and the existing publicly available power connection technology will not be described in detail in the article.
