Description

Technical Field

[0001] The utility model relates to the field of lithium battery manufacturing, in particular to a material extraction device for a lithium battery mixer. Background Art

[0002] In the lithium battery manufacturing process, components such as active materials, conductive carbon black, dispersants, adhesives and additives need to be added to the mixer in a certain proportion and order to form a stable fixed suspension.

[0003] During the lithium battery stirring process, it is necessary to sample and test the stirring material in the rotating inner cylinder. The existing structure of the lithium battery mixer (rotating inner cylinder) generally uses a suction rod for sampling. That is, when the slurry needs to be taken out, the sampling suction rod is manually placed in the rotating inner cylinder of the lithium battery mixer, and the sampling is done manually. After the sampling is completed, the sampling suction rod is taken out. The whole operation is extremely inconvenient and easy to contaminate the slurry. The traditional mixing drum is provided with a material taking device (such as patent CN220835388U), which adopts the method of completely installing the material taking device in the mixing drum. Since the material taking structure is always placed in the stirring material, it is easy to get blocked, and the material taking device placed in the barrel is not convenient for maintenance.

[0004] Therefore, in order to solve the above problems, a lithium battery mixer pumping device is needed to solve the above production problems. Utility Model Content

[0005] In view of this, the lithium battery mixer extraction device of the present technical solution installs a discharge valve on the mixer cover and cooperates with the discharge valve to install a extraction mechanism, so that the extraction end of the extraction mechanism passes through the discharge valve and extends into the mixer. When extraction is required, the extraction mechanism can be extended into the mixing drum, and when the mixing mechanism needs to mix the material, the extraction mechanism can be retracted. The overall mechanism is convenient for material extraction and detection without affecting the normal mixing of the material, avoiding the traditional method of manually using a material extraction rod to extend into the mixing drum to extract the material, thereby avoiding material contamination. At the same time, the device does not extend into the mixing drum, is not prone to blockage, and reduces the number of equipment maintenance times.

[0007] Furthermore, the extraction mechanism includes a cylinder assembly, a extraction rod assembly used in conjunction with the cylinder assembly, and a extraction seat assembly installed on the discharge valve. The cylinder assembly is telescopically driven to drive the extraction rod assembly to telescopically extract materials along the axial direction of the extraction seat assembly.

[0008] Furthermore, the extraction rod assembly includes an extraction head used in conjunction with the cylinder assembly, an extraction tube connected to the extraction head, and a sealing sleeve sleeved on the end of the extraction head. The cylinder assembly is extended and retracted to drive the extraction head to retract and retract.

[0009] Furthermore, the material extraction seat assembly includes a base installed on the discharge valve, a guide sleeve arranged between the base and the cylinder assembly, and a support rod, and the support rod is connected between the cylinder assembly and the base.

[0010] Furthermore, the guide sleeve is externally mounted on the draw rod assembly, and a sleeve slot for sliding the draw rod assembly is provided on the guide sleeve. There are two support rods, and the two support rods are symmetrically arranged relative to the guide sleeve.

[0011] Furthermore, a plurality of oil seals are arranged between the material extraction pipe and the base, and a sealing pressure plate used in conjunction with the oil seal is installed on the base. The sealing pressure plate is sleeved on the material extraction pipe and the lower end of the guide sleeve is pressed against the sealing pressure plate.

[0012] Furthermore, the cylinder assembly includes a cylinder base and a driving cylinder fixedly mounted on the cylinder base. The driving cylinder cooperates with the drawing head and drives the drawing head to telescopically move along the axial direction of the lithium battery mixer.

[0013] Furthermore, it also includes a slurry sampling valve and a slurry discharge control valve installed on the pumping head.

[0014] The beneficial effects of the utility model are as follows: the lithium battery mixer extraction device of the technical scheme installs a discharge valve on the mixer cover and cooperates with the discharge valve to install a extraction mechanism, so that the extraction end of the extraction mechanism passes through the discharge valve and extends into the mixer, and the extraction mechanism can be extended into the mixing drum when extraction is required, and the extraction mechanism can be retracted when the mixing mechanism needs to mix the material.
