Abstract
Description
Technical Field
[0001] This utility model belongs to the field of lithium battery processing technology and relates to a blowing and washing mechanism for cylindrical lithium batteries. Background Technology
[0002] Before coating lithium batteries with an outer film, they need to be cleaned to remove surface dust and other impurities. In the existing technology, each cylindrical lithium battery is usually rolled through a mesh conveyor line, and a blowing device is set above the conveyor line to blow and wash the surface of the battery. This blowing and washing method takes up a lot of space and it is difficult to ensure that secondary pollution does not occur during the blowing and washing process. Utility Model Content
[0003] The purpose of this invention is to address the aforementioned problems in existing technologies by providing a cleaning mechanism for cylindrical lithium batteries. The technical problem this invention aims to solve is how to improve the cleaning effect.
[0004] The objective of this utility model can be achieved through the following technical solution: a blowing and washing mechanism for a cylindrical lithium battery, characterized in that it includes a blowing and washing pipe, an inlet pipe and an outlet pipe, wherein the inlet pipe and the outlet pipe are respectively connected to the two ends of the blowing and washing pipe, the blowing and washing pipe has a spiral guide plate inside, and both the inlet pipe and the outlet pipe have an annular elastic diaphragm; in its natural state, the aperture of the through hole in the middle of the elastic diaphragm is smaller than the outer diameter of the cylindrical lithium battery; the two ends of the blowing and washing pipe are respectively provided with an air inlet pipe and an air outlet pipe, and the air inlet pipe is connected to the air outlet of an air pump.
[0005] Furthermore, the feed pipe has a conical hopper at its inlet.
[0006] Cylindrical lithium batteries are fed one by one through the feed pipe, and after passing through the blow-wash pipe, they are pushed out through the discharge pipe. During this process, the airflow is spiraled downward between the spiral guide plate and the outer circumference of the lithium battery, cleaning the outer surface of the lithium battery. The elastic diaphragm is used to seal and prevent airflow from escaping, ensuring that most of the airflow can be discharged from the exhaust pipe. Only the cylindrical lithium batteries have a small amount of air leakage at the electrode contact position. At the same time, the elastic diaphragm is also used to scrape dust from the outer wall of the lithium battery, achieving the dual effect of blowing and scraping. Attached Figure Description
[0007] Figure 1 This is a schematic diagram of the lithium battery blowing and washing structure.
[0008] Figure 2 yes Figure 1 A magnified view of part A in the middle.
[0009] In the diagram, 1 is the rinsing pipe; 2 is the feed pipe; 3 is the discharge pipe; 4 is the guide plate; and 5 is the elastic diaphragm. Detailed Implementation
[0010] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0011] like Figure 1 and Figure 2 The blowing and washing mechanism shown includes a blowing and washing pipe 1, an inlet pipe 2, and an outlet pipe 3. The inlet pipe 2 and the outlet pipe 3 are respectively connected to the two ends of the blowing and washing pipe 1. The blowing and washing pipe 1 has a spiral guide plate 4 inside. Both the inlet pipe 2 and the outlet pipe 3 have an annular elastic diaphragm 5. In its natural state, the diameter of the through hole in the middle of the elastic diaphragm 5 is smaller than the outer diameter of the cylindrical lithium battery. The two ends of the blowing and washing pipe 1 are respectively provided with an air inlet pipe and an air outlet pipe. The air inlet pipe is connected to the air outlet of an air pump. The inlet of the inlet pipe 2 has a conical hopper.
[0012] Cylindrical lithium batteries are fed one by one into the feed pipe 2, and after passing through the blow-wash pipe 1, they are pushed out from the discharge pipe 3. During this process, the airflow is discharged in a spiral downward state between the spiral guide plate 4 and the outer peripheral surface of the lithium battery, cleaning the outer surface of the lithium battery. The elastic diaphragm 5 is used for sealing to prevent airflow from escaping, ensuring that most of the airflow can be discharged from the exhaust pipe. Only the cylindrical lithium battery has a small amount of air leakage at the electrode contact position. At the same time, the elastic diaphragm 5 is also used to scrape dust from the outer wall of the lithium battery, achieving the dual effect of blowing and scraping.

Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
