Description

TECHNICAL FIELD

[0001] The utility model relates to lithium electricity crushing and packaging system technical field, specifically related to a kind of feeding dust removal device for lithium electricity crushing and packaging system. BACKGROUND

[0002] In the preparation of lithium battery positive material, the process of packaging lithium battery powder is involved. In the prior art, the packaging of lithium battery powder is usually carried out on a semi-automatic or semi-automatic packaging production line. A feeding station is provided on the lithium battery powder conveying production line. The packaging bag (such as a ton bag) for packaging lithium battery powder is opened by a packaging manipulator and placed on the weighing table of the feeding station. The lithium battery powder is poured into the packaging bag through the feeding pipe from above. When the feeding reaches the set weight, the feeding is stopped, and the bag opening is clamped by the packaging manipulator and transferred to the automatic bag sealing station for heat sealing of the bag opening, thereby completing the packaging of the ton bag.

[0003] The problem in the above-mentioned ton bag packaging process is that, in order to ensure the accuracy of feeding, the feeding pipe cannot form a sealed contact or force contact with the bag opening of the ton bag, so as not to affect the accuracy of the weighing measurement. However, this may cause the lithium battery powder to fall into the packaging bag by gravity, which may cause the lithium battery powder to fly and escape, thereby polluting the surrounding environment. SUMMARY

[0004] To solve the above problems, the utility model provides a feeding dust removal device for lithium electricity crushing and packaging system, which aims to ensure the accuracy of feeding while preventing the escape of lithium battery dust during feeding.

[0016] The first inflatable disc and the second inflatable disc are made of rubber material, and an annular cavity is arranged in the first inflatable disc and the second inflatable disc.

[0017] Preferably, a plurality of limiting pins are arranged between the upper and lower walls of the annular cavity of the first inflatable disc and the second inflatable disc, and the limiting pins are used for limiting the expansion of the first inflatable disc and the second inflatable disc in the up-down direction.
