Description

Technical Field

[0001] The utility model relates to the field of box loading and conveying, in particular to a box loading and unloading device. Background Art

[0002] Before tobacco processing, the cigarette packs packaged in cartons need to be unpacked and unloaded. However, the existing box loading and unloading process requires manual unloading of the unpacked box loading into the assembly line for material transportation. This is not only time-consuming and labor-intensive, but also inconvenient for workers to lift the box loading and turn over the box to unload the material when encountering a high assembly line. Therefore, a box turning and unloading device is needed to unload the material.

[0003] A Chinese patent with publication number CN220948940U discloses an automatic unpacking device for boxed materials, including an elevator, a box turning and unloading device is fixedly installed at the lower end of the elevator, a third roller conveyor, a second roller conveyor and a first roller conveyor are fixedly installed in sequence on the side of the box turning and unloading device away from the elevator, a clamping car is arranged on the side of the first roller conveyor away from the second roller conveyor; a cable tie cutting device is fixedly installed on the end of the second roller conveyor close to the first roller conveyor, and an outer box grabbing device is fixedly installed on the end of the second roller conveyor close to the third roller conveyor; the beneficial effects are: the support plate and the carton are fitted together through the flexibility of the support plate, the damage of the outer box is avoided, the reuse rate of the outer box is improved, the production cost of the workshop is saved, the labor intensity of the operator is reduced by automatically grabbing and placing the outer box, and the unloading effect of the material box is improved.
