Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of turnover box automation processing production line, belong to logistics transport equipment field. BACKGROUND

[0002] With the high-speed development of modern manufacturing and logistics industry, turnover box is widely used in chemical industry, electronics, pharmaceutical, food and other fields as the core carrier of material storage and transportation. The turnover box involved in the present application is made of metal material, including a bottom plate and four side wall plates. When the turnover box is in a stacked state, the four side wall plates are folded and placed in sequence. When the turnover box is in an open state, the four side wall plates are overlapped in sequence, and the adjacent side wall plates are connected and fixed by a lock catch. The processing and operation of traditional turnover boxes are mainly completed by manual work. The workers need to assist with a forklift to separate the stacked empty turnover boxes into individual empty boxes and arrange them neatly. Then the workers manually unfold the four folded wall plates of the turnover box and lock the lock catch to realize the opening of the turnover box. After that, the workers manually unfold, arrange and line the pre-made film bag inside the turnover box to prevent direct contact between the material and the box wall. In the prior art, there are devices for making and unfolding the film bag, which are only applied to small paper boxes. Since the film bag cannot be tightly attached to the inner wall of the box, and the manual opening process is not compatible with the mechanical bag-making and lining process, it is easy to cause disorder in the production rhythm, and the film bag in the turnover box is manually lined and attached. The processing and operation of traditional turnover boxes have low processing efficiency, low automation degree and high labor intensity. Moreover, since the box body is made of metal material, it is easy to cause safety accidents such as wall plate collapse and lock catch pinching during manual opening by workers, which poses a great safety hazard.
