[0002] Lithium-ion batteries are a type of battery that uses lithium metal or lithium alloy as the negative electrode material and a non-aqueous electrolyte solution. The materials for lithium-ion battery cells are prepared by physical mixing to obtain different mass ratios, thus requiring a proportioning device. However, existing proportioning devices are prone to condensation of the raw material powders used for proportioning due to moisture, lack suitable and efficient heating and stirring mechanisms, and the heating and stirring mechanisms are prone to damage after prolonged use, resulting in high replacement costs and inconvenience for individual replacement. In addition, the top cover of the device is complicated to disassemble and assemble, and lacks a suitable quick maintenance opening and closing mechanism. Utility Model Content

[0006] The present invention is further configured such that a plurality of heating plates are provided on both sides of the inner wall of the heating box, and the plurality of heating plates are arranged alternately for convenient and efficient heating.

[0007] The present invention is further configured such that each of the two air guide pipes is equipped with a fan, and each of the two air guide pipes is equipped with a filter screen on the side near the rotating shaft, so as to achieve efficient air delivery and guidance.

[0008] The present invention is further configured such that each of the two stirring seats is symmetrically provided with a plurality of positioning holes, and the rotating shaft is provided with positioning rods corresponding to the plurality of positioning holes, which facilitates installation and positioning.

[0009] The present invention is further configured such that each end of the plurality of positioning rods is provided with a positioning ring, and the positioning ring and the positioning rod are threadedly connected to achieve installation and locking.

[0011] (III) Beneficial Effects Compared with the prior art, this utility model provides a lithium battery raw material proportioning device, which has the following beneficial effects: 1. Through the design of the stirring base, the device generates hot air through the heating chamber, which is then delivered to the T-shaped air guide groove of the rotating shaft via a fan and air guide pipe, and finally introduced into the heat conduction groove inside the stirring base. This design allows heat to be directly and evenly conducted to the stirring base and fully exchanged with the materials inside the cylinder, avoiding the problems of low thermal efficiency and uneven heating caused by traditional external wall heating. It achieves synchronous, efficient, and uniform heating of lithium battery raw materials during the stirring process, effectively improving mixing and drying efficiency.

[0012] 2. Through the design of the positioning rod, the stirring seat is precisely installed by engaging with the positioning rod on the rotating shaft via the positioning hole, and is locked in place by the threaded positioning ring. This detachable connection method allows individual stirring seats to be replaced independently after wear or damage, without scrapping the entire stirring shaft or drive mechanism, greatly reducing subsequent maintenance costs and the complexity of component replacement, and improving the economic efficiency and ease of maintenance of the equipment.

[0013] 3. The design incorporates an inspection plate. An inspection slot is created on the front face of the cylinder and enclosed by a removable inspection plate, secured with bolts. This design changes the traditional maintenance method that requires disassembling the entire cylinder top cover or large cover plate. When inspection or cleaning of the interior is needed, simply removing the front inspection plate directly exposes the internal space. The direct operating passage and spacious operating area make daily inspections, troubleshooting, and internal cleaning exceptionally time-saving and labor-saving, significantly improving the maintainability of the equipment.

[0024] Please see Figure 3 and Figure 4As an implementation method for efficient heating: several heating plates 14 are provided on the inner walls of both the left and right ends of the heating box 4, and the several heating plates 14 are arranged alternately. A fan 15 is provided inside each of the two air guide pipes 5, and a filter screen 16 is provided on the side of each of the two air guide pipes 5 near the rotating shaft 3.

After the mixing is completed, the valve of the bottom discharge pipe is opened to discharge the materials outward.

[0031] During the stirring and heating process, the control device with its own control system starts the fan 15 and multiple heating plates 14. The heating plates 14 are arranged in an alternating manner to form an efficient heating path. The fan 15 efficiently guides and transports the internal air.
