Description

Technical Field

[0001] The utility model relates to a feeding device, in particular to a conductive agent feeding device for lithium electronic batteries. Background Technique

[0002] With the continuous progress of technology and the urgent global demand for clean energy, lithium batteries have become the leading technology in the field of energy storage due to their high energy density, long life, and environmental friendliness. In the structure of lithium batteries, conductive agents play a crucial role. They not only promote electron conduction between the positive and negative electrodes but also assist in the efficient movement of ions, thus greatly improving the overall performance of the battery. The conductive agents of lithium-ion batteries usually exist in the form of powders and are the key components to ensure the smooth flow of electrons inside the battery. During the battery manufacturing process, the addition and distribution of conductive agents are particularly critical, directly affecting the conductivity, stability, and ultimate energy efficiency of the battery.

[0003] In the existing conductive agent feeding device, manual experience is relied on for the initial proportioning. Such proportioning is difficult to control the weight of the conductive agent feeding, easily resulting in short weight of the feeding, thus leading to relatively large errors. To improve the accuracy of the feeding, there is an urgent need for a conductive agent feeding device for lithium electronic batteries to solve the above deficiencies.

[0004] Therefore, it is necessary to design a conductive agent feeding device for lithium electronic batteries to solve the above technical problems. Content of the Utility Model

[0005] In order to overcome the disadvantages of being difficult to control the weight of the conductive agent feeding, easily resulting in short weight of the feeding and thus relatively large errors, the purpose of the utility model is to provide a conductive agent feeding device for lithium electronic batteries.

[0006] The technical solution is as follows: A conductive agent feeding device for lithium electronic batteries includes a support frame, a material box, a mixing barrel, a water pump, a push plate, and a first electric push rod. More than one material box is fixedly connected in a circular array at the top of the support frame. A mixing barrel is fixedly connected inside the support frame. A water pump is fixedly connected to the top of the support frame. The water pump is connected and communicated with the mixing barrel through a pipeline. A first electric push rod is fixedly connected to one side of each material box. The telescopic rod of each first electric push rod is fixedly connected with a push plate, and the push plates are all slidably connected to the bottom of the corresponding material boxes.

[0007] As an improvement of the above solution, it further includes an electronic scale, a second electric push rod, and a feeding frame. Electronic scales are symmetrically placed on both sides of the top of the support frame. The electronic scales are located below the push plates. More than one second electric push rod is fixedly connected in a circular array at the top of the mixing barrel. A feeding frame is slidably connected to one side of each second electric push rod.

[0008] As an improvement to the above solution, it further includes a motor, a stirring rod, a valve and a conveyor. The top of the mixing drum is fixedly connected with a motor, and the output shaft of the motor is fixedly connected with a stirring rod located inside the mixing drum. The middle and lower part of the mixing drum is connected and communicated with a valve, and the bottom of the mixing drum is fixedly connected with a conveyor.

[0009] As an improvement to the above solution, feeding openings are provided on all sides of the mixing drum.

[0010] As an improvement to the above solution, the middle and lower part structure of the mixing drum is funnel-shaped.

[0011] As an improvement to the above solution, the inside of the conveyor is in a spiral state.

[0012] The utility model has the following advantages: 1. By controlling the first electric push rod to push the push plate, the material falls from the material box onto the electronic scale for weighing, so that the weight of the conductive agent injection can be accurately controlled, thus solving the problem of large manual proportioning error and improving the accuracy of injection.

[0013] 2. By using the second electric push rod to push the feeding frame into the mixing drum, the material is conveyed into the mixing drum, eliminating the need for manual feeding, thus reducing the labor intensity of workers and improving work efficiency. Description of the Drawings

Detailed Description of the Invention

[0020] The above solution will be further described below in conjunction with specific embodiments. It should be understood that these embodiments are for illustrating the present application and not for limiting the scope of the present application. The implementation conditions adopted in the embodiments can be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not specified are usually the conditions in conventional experiments.

[0021] Embodiment: A feeding device for conductive agents of lithium - ion batteries, as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 shown, includes a support frame 1, a material box 2, a stirring cylinder 3, a water pump 4, a push plate 5, a first electric push rod 6, an electronic scale 7, a second electric push rod 8 and a feeding frame 9. Four material boxes 2 are welded in a circular array at the top of the support frame 1. A stirring cylinder 3 is welded inside the support frame 1. The lower - middle part of the stirring cylinder 3 is funnel - shaped. A water pump 4 is installed on the right side of the top of the support frame 1 through screws. The water pump 4 is connected and communicated with the stirring cylinder 3 through a pipeline. A first electric push rod 6 is installed on the side of each material box 2 away from the stirring cylinder 3 through screws. The telescopic rod of each first electric push rod 6 is welded with a push plate 5, and the push plate 5 is slidably connected to the bottom of the corresponding material box 2. Electronic scales 7 are placed symmetrically left and right on the front and back sides of the top of the support frame 1. The electronic scales 7 are located directly below the push plates 5. Four second electric push rods 8 are welded in a circular array at the top of the stirring cylinder 3. A feeding frame 9 is slidably connected to the side of each second electric push rod 8 away from the stirring cylinder 3. Feeding ports are provided around the stirring cylinder 3 to facilitate the feeding frame 9 to feed materials into the stirring cylinder 3.

[0022] When the staff uses this equipment, first, the materials need to be poured into the material box 2. Then, the first electric push rod 6 is started. The telescopic rod of the first electric push rod 6 pushes the push plate 5 to the side away from the stirring cylinder 3. When the push plate 5 no longer blocks the feeding port of the material box 2, the materials will fall onto the electronic scale 7 for weighing. After weighing, the telescopic rod of the first electric push rod 6 drives the push plate 5 to reset and block the feeding port of the material box 2. Then, the second electric push rod 8 is started. The telescopic rod of the second electric push rod 8 drives the feeding frame 9 to convey the materials into the stirring cylinder 3, so that the materials fall into the stirring cylinder 3. After that, the second electric push rod 8 drives the feeding frame 9 to reset.

[0023] As Figure 2 and Figure 3 shown, it further includes a motor 10, a stirring rod 11, a valve 12 and a conveyor 13. A motor 10 is installed on the top of the stirring cylinder 3 through screws. A stirring rod 11 located inside the stirring cylinder 3 is welded on the output shaft of the motor 10. A valve 12 is connected and communicated with the lower - middle part of the stirring cylinder 3. A conveyor 13 is connected to the bottom of the stirring cylinder 3 through screws. The inside of the conveyor 13 is in a spiral state.

[0024] When the material falls into the mixing drum 3, the motor 10 can be started immediately. The motor 10 drives the mixing rod 11 to rotate through the output shaft to mix the material. Some lithium-ion battery conductive agent feedings may be solid-liquid mixtures. If it is a solid-liquid mixture, water can be pumped from the water pump 4 into the mixing drum 3 for mixing. After the material is mixed, the valve 12 is opened, and the mixed material will flow into the conveyor 13 along the mixing drum 3 and then be conveyed by the conveyor 13 to the next manufacturing process to complete the feeding of the lithium-ion battery conductive agent. Subsequently, the motor 10 is turned off and the mixing rod 11 stops rotating. If it is necessary to feed the lithium-ion battery conductive agent again, the above operations can be repeated.
