For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0030] The embodiments of this utility model will be described below based on its overall structure.

[0031] A lithium iron phosphate production equipment, such as Figures 1-4 As shown, the device includes a housing 1 and a feeding mechanism 6. The feeding mechanism 6 includes a first feeding pipe 601. A retaining tube 602 is provided on one side of the inner wall of the first feeding pipe 601. A retaining plate 603 is engaged and slidably mounted inside the retaining tube 602. A movable valve 604 is provided at one end of the retaining plate 603. One side of the movable valve 604 is connected to the inner wall of the first feeding pipe 601 via a rotating shaft. A fixing block 605 is provided on the outer surface of the first feeding pipe 601. A sliding groove 612 is provided inside the fixing block 605. An electric push rod 606 is provided in the sliding groove 612. A slider 607 is provided at one end of the electric push rod 606. A weighing sensor 608 is installed in the top mounting slot of 7. A hopper 609 is installed at the top of the first feeding pipe 601. A second feeding pipe 610 is installed at the top of the hopper 609. A solenoid valve 611 is installed on the second feeding pipe 610. A movable valve 604 is connected to the inner wall of the first feeding pipe 601 through a rotating shaft. It can flexibly open or close the feeding channel according to production needs, thereby accurately controlling the amount of raw materials added. The second feeding pipe 610 provides a channel for raw materials to enter the hopper. The solenoid valve 611 on it can remotely control the flow of raw materials, further enhancing the controllability of the feeding process.

[0032] See Figure 2There are two clamping tubes 602. The two clamping tubes 602 are symmetrically arranged along the central axis of the first feeding tube 601. The two clamping tubes 602 are symmetrically arranged to provide stable support for the first feeding tube 601 and can evenly distribute the force generated during the feeding process. The symmetrically arranged clamping tubes 602 can better cooperate with the first feeding tube 601 to form a tight sealing structure, which can effectively prevent the raw materials from leaking during the feeding process.

[0033] See Figure 3 There are two electric push rods 606, which are symmetrically arranged along the central axis of the slide groove 612. The two electric push rods 606 are symmetrically arranged and can synchronously push the slider 607 to slide in the slide groove 612, making the feeding action more stable and reliable. The two symmetrically arranged electric push rods 606 support each other in structure, which enhances the overall rigidity of the feeding mechanism 6.

[0034] See Figure 1 A mounting bracket 2 is provided on one side of the outer casing 1, and a motor 3 is mounted on the mounting bracket 2. By mounting the motor 3 on the mounting bracket 2 and fixing it to one side of the outer casing 1, the entire equipment structure becomes more compact. The mounting bracket 2 provides a stable mounting platform for the motor 3, ensuring the stability and safety of the motor during operation.

[0035] See Figure 4 The output end of the motor 3 is connected to a rotating rod 7, and a screw ribbon 8 is provided on the rotating rod 7. During the mixing process, the screw ribbon 8 can also shear and disperse the raw materials to a certain extent, which helps to break up the agglomerates in the raw materials and further improve the mixing effect. The screw ribbon 8 on the rotating rod 7 moves with the rotation of the rotating rod 7, which can effectively stir and mix the raw materials in the outer shell 1.

[0036] See Figure 1 The outer casing 1 is surrounded by a base 4, and the bottom of the outer casing 1 is provided with a discharge port 5. The base 4 provides stable support for the outer casing 1. During the production process, the equipment may be affected by various forces, such as vibration and impact. The discharge port 5 ensures that the mixed lithium iron phosphate can be smoothly discharged from the equipment, ensuring that the material can flow out evenly and continuously, avoiding the problems of blockage or material accumulation.

[0037] See Figure 3 The load cell 608 is model CZL133. The CZL133 load cell 608 typically has high-precision measurement capabilities, ensuring that the preset accurate weight is achieved every time material is added, thereby improving the consistency of product quality. The CZL133 sensor takes into account the stability of long-term use. Even in the face of complex and changing environmental conditions, the load cell 608 can maintain stable measurement performance and reduce errors caused by environmental changes.

[0038] The implementation principle of this utility model is as follows: First, the raw material is added into the hopper 609 through the second feeding pipe 610. Then, the raw material falls onto the movable valve 604. The raw material presses down on the weighing sensor 608 by gravity. When the weighing sensor 608 detects that the weight of the raw material reaches the set threshold, the external control console controls the electric push rod 606 to drive the slider 607 to slide in the slide groove 612 through an electrical signal. This causes the movable valve 604 to fall down and the solenoid valve 611 to close, allowing the raw material to fall into the lower outer shell 1 and be mixed through the screw ribbon 8. At the same time, the electric push rod inside the buckle 602 drives the buckle plate 603 to extend, causing the movable valve 604 to rotate to the horizontal. Then, the electric push rod 606 drives the slider 607 to slide out in the slide groove 612. After that, the solenoid valve 611 opens to continue adding material into the hopper 609. The raw material after mixing is transported to the subsequent processing stage through the discharge port 5.

[0039] All parts not covered in this utility model are the same as or can be implemented using existing technologies, and will not be described in detail here.
