Description

Technical Field

[0001] This utility model relates to the field of headphone lithium battery production technology, specifically a double-star mixer for headphone lithium battery production. Background Technology

[0002] Headphone lithium batteries are lithium-ion batteries specifically designed to provide power to headphones. They belong to the category of miniaturized, high-energy-density lithium batteries. Their core characteristics are small size and light weight, while also possessing high energy density. They can store enough electricity within a limited volume to support headphones achieving a long battery life. In the production process of headphone lithium batteries, various raw materials need to be thoroughly stirred and mixed to ensure the performance and quality of the battery.

[0003] However, the existing Shuangxing mixer used in the production of lithium batteries for headphones still has some problems in use: Existing dual-star mixers used in the production of headphone lithium batteries typically employ a single stirring paddle structure. During stirring, the raw materials tend to form vortices within the stirring container, preventing some materials from being fully stirred. Furthermore, the stirring range is limited, which cannot adequately meet the high requirements for stirring precision and uniformity of raw materials in the production of headphone lithium batteries. Therefore, we propose a dual-star mixer for the production of headphone lithium batteries to solve the problems mentioned above. Utility Model Content

[0004] The purpose of this utility model is to provide a dual-star mixer for the production of headphone lithium batteries, in order to solve the problem mentioned in the background art that the dual-star mixer for the production of headphone lithium batteries usually adopts a single stirring paddle structure. During stirring, the raw materials are prone to forming vortices in the stirring container, which makes it impossible for some raw materials to be fully stirred, and the stirring range is limited. It cannot well meet the high requirements for the stirring precision and uniformity of raw materials in the production of headphone lithium batteries.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dual-star mixer for the production of headphone lithium batteries, comprising a base and a frame. A frame is welded to the top of the base, and a controller is installed on the outer side of the frame. A planetary gearbox is connected to the upper flange of the frame. A main motor and an auxiliary motor are installed inside the planetary gearbox. A first drive shaft is movably connected to the output end of the main motor. Three sets of first stirring paddles are bolted to the outer surface of the first drive shaft. A second drive shaft is movably connected to the output end of the auxiliary motor. A second stirring paddle is bolted to the outer surface of the second drive shaft. Two sets of mounting seats are bolted to the top of the base, and the two sets of mounting seats are symmetrically designed about the base. An electric push rod is fixed above the two sets of mounting seats. A bracket is provided on one side of the frame. Fixing blocks are welded to both ends of the bracket, and the output end of the electric push rod is fixedly connected to the bottom of the fixing block. A mixing tank is installed in the middle of the bracket.

[0006] By adopting the above technical solution, the main motor in the planetary gearbox drives the first drive shaft and the first stirring paddle, and the auxiliary motor drives the second drive shaft and the second stirring paddle to stir the materials in the mixing tank at different speeds and directions. At the same time, the electric push rod can push the support and the mixing tank to lift and lower, thereby enhancing the stirring effect. This achieves efficient and uniform mixing of electrode materials in the production of headphone lithium batteries, reduces stirring dead zones, and improves the quality and consistency of battery production.

[0007] Preferably, the first impeller is a turbine impeller and the second impeller is a helical impeller, and the first impeller and the second impeller are designed to rotate in opposite directions.

[0008] Using the above technical solution, the high-speed rotation of the turbine agitator generates strong shearing force, which can break up material agglomerates; the rotation of the spiral agitator promotes the axial and radial flow of the material, and the opposite rotation of the two enhances the relative motion between the materials, which can fully disperse the lithium battery electrode materials at the micro level and uniformly mix them at the macro level, improve the stirring efficiency and quality, and ensure the stability of battery performance.

[0009] Preferably, two sets of slide rails are welded to one side of the frame, and two sets of sliders that are slidably connected to the slide rails are welded to the rear end of the bracket.

[0010] By adopting the above technical solution, a slide rail is set on the frame and a matching slider is set at the rear end of the support. The sliding characteristics of the slider in the slide rail enable the support to move linearly along the slide rail. When the electric push rod pushes the support, the slide rail and the slider work together to guide and stabilize, ensuring that the support rises and falls smoothly, thereby allowing the mixing tank to move stably, improving the mixing effect and the safety of equipment operation.

[0011] Preferably, the slide rail has a T-shaped structure, and the middle part of the slider is adapted to the shape of the slide rail.

[0012] By adopting the above technical solution, the T-shaped slide rail and the matching slider form a specific engagement relationship. When the slider slides on the slide rail, the T-shaped structure can limit the slider from moving excessively in other directions perpendicular to the sliding direction. This can effectively prevent the support from shaking or shifting during the lifting process, ensuring the stability and accuracy of the movement of the support and mixing tank, and ensuring the smooth progress of the mixing work.

[0013] Preferably, two sets of locking blocks are symmetrically welded on the inner side of the bracket, a first insertion hole is provided in the middle of the locking block, and supports are welded on both sides of the mixing tank. A locking groove adapted to the locking block is provided in the middle of the support, and the locking block is slidably connected to the support through the locking groove. A second insertion hole is provided in the middle of the support, and a pin passes through the middle of the first insertion hole and the second insertion hole.

[0014] By adopting the above technical solution, the mixing box can be quickly positioned on the bracket by using the sliding connection between the card block and the matching slot on the support. Then, the mixing box is fixed to the bracket by the cooperation of the first insertion hole, the second insertion hole and the pin. This not only facilitates the installation and disassembly of the mixing box and improves the efficiency of equipment assembly and maintenance, but also ensures that the connection between the mixing box and the bracket is stable during the mixing process, and avoids the mixing box shaking during the mixing process, which affects the mixing effect.

[0015] Preferably, the bottom of the mixing tank is equipped with four sets of casters.

[0016] By adopting the above technical solution, the caster wheel, through its flexible rotating wheel structure, can change its direction of travel, allowing the mixing tank to move in any direction on a horizontal surface, reducing the difficulty and labor intensity of manual handling, and improving the convenience of production operations.

[0017] Compared with the prior art, the beneficial effects of this utility model are: 1. The main motor drives the first drive shaft, which in turn drives the first agitator, which is in the form of a turbine agitator, to rotate at high speed. This generates strong shearing force, which quickly breaks up material agglomerates, making the material particles finer and more evenly distributed. The auxiliary motor drives the second drive shaft, which drives the second agitator, which is in the form of a spiral agitator, to rotate and push the material to flow in the axial and radial directions. The two motors rotate in opposite directions, which greatly enhances the relative motion between the materials and creates a complex and thorough mixing environment. This ensures that the electrode materials required for the production of headphone lithium batteries can be mixed efficiently and evenly, effectively improving product quality and consistency. 2. The sliding connection between the slots on the supports on both sides of the mixing tank and the inner blocks of the bracket allows the mixing tank to be quickly and accurately positioned and installed on the bracket, greatly improving installation efficiency. The first and second insertion holes on the blocks and supports, respectively, allow for the insertion of pins after alignment, which securely fixes the mixing tank to the bracket. This effectively prevents the mixing tank from shaking or shifting due to vibration or external forces during mixing, ensuring stable and reliable mixing and guaranteeing the mixing quality of electrode materials in the production of headphone lithium batteries.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Please see Figures 1-4This utility model provides a technical solution: a dual-star mixer for the production of headphone lithium batteries, including a base 1 and a frame 2. The frame 2 is welded on the top of the base 1. A controller 3 is installed on the outside of the frame 2. A planetary gearbox 4 is connected to the top flange of the frame 2. A main motor 5 and an auxiliary motor 8 are installed inside the planetary gearbox 4. The output end of the main motor 5 is movably connected to a first drive shaft 6. Three sets of first stirring paddles 7 are bolted to the outer surface of the first drive shaft 6. The output end of the auxiliary motor 8 is movably connected to a second drive shaft 9. A second stirring paddle 10 is bolted to the outer surface of the second drive shaft 9. Two sets of mounting seats 11 are bolted to the top of the base 1, and the two sets of mounting seats 11 are symmetrically designed about the base 1. An electric push rod 12 is fixed above the two sets of mounting seats 11. A bracket 13 is provided on one side of the frame 2. Fixing blocks 14 are welded to both ends of the bracket 13, and the output end of the electric push rod 12 is fixedly connected to the bottom of the fixing block 14. A mixing tank 19 is installed in the middle of the bracket 13. The first agitator 7 is a turbine agitator, and the second agitator 10 is a helical agitator, with the first agitator 7 and the second agitator 10 rotating in opposite directions. Two sets of slide rails 15 are welded to one side of the frame 2, and two sets of sliders 16 that are slidably connected to the slide rails 15 are welded to the rear end of the support 13. The slide rails 15 have a T-shaped structure, and the middle part of the sliders 16 is adapted to the shape of the slide rails 15.

[0022] The base 1 provides stable support for the entire equipment. The frame 2 is welded to the base 1 to form the main framework. The controller 3 installed on the outside is used to control the operation of the equipment. Inside the planetary gearbox 4 connected by a flange on the top of the frame 2, after the main motor 5 and the auxiliary motor 8 start, the main motor 5 drives the first drive shaft 6 to rotate, causing the first agitator 7, which acts as a turbine agitator, to rotate at high speed, generating strong shear force to break up material agglomerates. The auxiliary motor 8 drives the second drive shaft 9 to rotate, causing the second agitator 10, which acts as a helical agitator, to rotate and push the material to flow axially and radially. The two rotate in opposite directions, enhancing the relative motion between the materials and achieving high material flow. The system achieves efficient and uniform mixing. Two sets of symmetrical mounting seats 11 on the base 1 fix electric push rods 12. The output end of the electric push rods 12 is connected to the fixing blocks 14 at both ends of the bracket 13, which can push the bracket 13 to rise and fall. Two sets of sliders 16 at the rear end of the bracket 13 are slidably connected to the T-shaped slide rail 15 welded to one side of the frame 2. The middle part of the slider 16 is adapted to the shape of the slide rail 15, which can guide and stabilize the bracket 13 when the electric push rod 12 pushes it, ensuring that the bracket 13 and the mixing box 19 installed in the middle rise and fall smoothly, thereby improving the mixing effect and the safety of equipment operation, and meeting the mixing requirements of electrode materials in the production of headphone lithium batteries.

[0023] Two sets of locking blocks 17 are symmetrically welded on the inner side of the bracket 13. A first insertion hole 18 is opened in the middle of the locking block 17. Supports 20 are welded on both sides of the mixing tank 19. A slot 21 that matches the locking block 17 is opened in the middle of the support 20. The locking block 17 is slidably connected to the support 20 through the slot 21. A second insertion hole 22 is opened in the middle of the support 20. A pin 23 passes through the middle of the first insertion hole 18 and the second insertion hole 22.

[0024] Two sets of locking blocks 17 are symmetrically welded to the inner side of the bracket 13. The first insertion hole 18 on the blocks 17 is engaged with the slots 21 and the second insertion hole 22 on the supports 20 welded to both sides of the mixing tank 19. During installation, the slots 21 on the supports 20 on both sides of the mixing tank 19 are aligned with the locking blocks 17 and slid in to achieve the initial positioning and connection of the mixing tank 19 on the bracket 13. At this time, the first insertion hole 18 and the second insertion hole 22 are aligned. Then, the pin 23 is inserted through the two to fix them. This not only facilitates the installation and disassembly of the mixing tank 19, but also enables the assembly and removal of the mixing tank 19 on the equipment quickly, improving production efficiency. It also ensures that the mixing tank 19 is firmly connected to the bracket 13 during the mixing process, preventing the mixing tank 19 from shaking or shifting due to vibration or external force generated by the mixing, thus ensuring the stable operation and quality of the mixing.

[0025] Four sets of casters 24 are installed at the bottom of the mixing tank 19.

[0026] The casters 24, with their flexible rotating wheel structure, can change the direction of travel, allowing the mixing tank 19 to move in any direction on the horizontal plane. This avoids the inconvenience and personnel injury that may be caused by the weight of the mixing tank 19, reduces the difficulty and labor intensity of manual handling, improves the convenience of production operations, and helps to optimize production operations and improve overall production efficiency.

[0027] Working principle: For this type of dual-star mixer used in the production of lithium batteries for headphones, the base 1 provides stable support for the equipment, the frame 2 forms the main framework, and the controller 3 controls the operation of the equipment. Inside the planetary gearbox 4, the main motor 5 drives the first drive shaft 6, causing the turbine-shaped first stirring paddle 7 to rotate at high speed, generating strong shearing force to break up material agglomerates. The auxiliary motor 8 drives the second drive shaft 9, causing the spiral-shaped second stirring paddle 10 to push the material axially and radially. The two rotating in opposite directions enhance the relative motion of the material to efficiently mix it. The electric push rod 12, fixed by the mounting base 11 on the base 1, pushes the fixing blocks 14 at both ends of the bracket 13, causing the slider 16 at the rear end of the bracket 13 to slide along the T-shaped slide rail 15 on one side of the frame 2, achieving smooth lifting and lowering. When installing the mixing box 19, the slots 21 of the supports 20 on both sides are aligned with the inner locking blocks 17 of the bracket 13 and slid in, so that the first insertion hole 18 is aligned with the second insertion hole 22 and then the pin 23 is inserted for fixation. The four sets of universal wheels 24 at the bottom of the mixing box 19 can rotate flexibly to change direction, facilitating its movement to facilitate installation, disassembly, and other operations.

[0028] This completes a series of tasks. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0029] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
