Description

Technical Field

[0001] The utility model relates to the technical field of packaging devices, in particular to a full-servo dry ice packaging device. Background Art

[0002] Dry ice is a white crystal that sublimates easily at room temperature and has a high heat of vaporization. When sublimating at normal pressure, it can rapidly reduce the surrounding temperature. Therefore, when dry ice sublimates in the air, it will liquefy and even further condense water vapor in the air. The formed water vapor droplets or small ice crystals adhere to the dust in the air to form the white smoke we can see. The crystal structure of dry ice is a simple cubic molecular crystal. Individual carbon dioxide molecules are located at the vertices and face centers of the cube in different orientations, accumulating to form dry ice crystals. Dry ice needs to be packaged after production. In order to better package dry ice, a full-servo dry ice packaging device is proposed.

[0003] For example, the feeding and packaging mechanism of a dry ice production line disclosed in the authorization publication number CN215205588U includes an ejection mechanism, a conveying mechanism, and a buffer mechanism. The ejection mechanism forms a 90° angle with the discharge conveyor belt and ejects the dry ice blocks on the discharge conveyor belt to the conveying mechanism. The conveying mechanism is used to feed the dry ice blocks one by one into the packaging machine. The buffer mechanism is provided at the entrance of the packaging machine to decelerate the dry ice blocks.

[0004] Although it realizes the feeding and packaging mechanism of the above-mentioned dry ice production line and can improve packaging efficiency, it does not solve the problem that the existing packaging device is not conducive to convenient self-rotating wrapping packaging of dry ice pallets and automatic cutting of packaging film during use, and is not conducive to uniform wrapping packaging of dry ice pallets, which affects the packaging effect.
