Description

TECHNICAL FIELD

[0001] The utility model relates specifically to a liquid fertilizer packaging device. BACKGROUND

[0002] Liquid fertilizer refers to the fertilizer that provides the required nutrition of plants in the form of water solution. Compared with solid fertilizer, liquid fertilizer has faster absorption speed and more direct action mode, and is suitable for foliar spraying or irrigation. In order to prevent leakage, the surface of the packaging bottle is covered with heat shrink film after the liquid fertilizer is packaged by the plastic bottle. When the film is heat shrunk, the film is heated to shrink by two symmetrical heating plates, so as to tightly adhere to the packaging bottle, so as to improve the sealing performance, thereby effectively preventing leakage during transportation and storage, and keeping the quality and concentration of the fertilizer stable.

[0003] In the process of covering the heat shrink film of the existing liquid fertilizer packaging bottle, the positions of the two heating plates are relatively fixed. When the packaging bottle is moved to the positions between the two heating plates by the conveying belt, the distance between the two heating plates and the packaging bottle is not convenient to adjust. When the distance is far from the packaging bottle, the heat is wasted by escaping into the air. When the distance between the two heating plates is close, the number of packaging bottles that can pass between the two heating plates is small, which affects the processing efficiency. Therefore, the liquid fertilizer packaging device is proposed. CONTENT OF THE UTILITY MODEL
