Description

TECHNICAL FIELD

[0001] The utility model relates to automatic packaging technical field. More specifically, the utility model relates to an industrial chrome acid anhydride bucket hoop automatic locking device. BACKGROUND

[0002] Chrome acid anhydride is a dangerous chemical, which can harm human health and environment. Inhaling it can cause acute poisoning. Therefore, its production and packaging process should avoid human intervention as much as possible. The bucket hoop is a device used to connect the lid and the barrel body together to achieve sealing and fastening. The conventional bucket hoop structure includes:

[0003] The bucket hoop body, handle and connecting piece, wherein the bucket hoop body is a ring body structure with a notch, one side of the notch of the bucket hoop body is hinged with the handle, and the other side of the notch of the bucket hoop body is hinged with one end of the connecting piece. The other end of the connecting piece is also hinged with the handle. When the bucket hoop needs to be tightened, the handle is pushed in the specified direction, which can drive the connecting piece to move, so that the two sides of the notch of the bucket hoop body are close to each other. After the handle is completely pressed onto the bucket hoop body, the tightening and fastening of the bucket hoop are completed.

[0004] The utility model patent with patent application number CN220536016U discloses a bucket hoop locking device for F1 area, which comprises a first adjusting mechanism, a second adjusting mechanism, a support plate and a locking mechanism arranged around an assembly station. The first adjusting mechanism can centrally position a container body placed in the assembly station. The second adjusting mechanism can centrally position a cover body combined with the container body. The support plate can support and limit a bucket hoop set at the joint of the cover body and the container body. The locking mechanism can push and press the bucket hoop body of the bucket hoop, and also can turn the handle of the bucket hoop to lock the cover body on the container body. Although this device can lock the bucket hoop, it cannot ensure that the bottom of the bucket hoop is tightly attached to the support plate during the fastening process. During the fastening process, the bucket hoop and the barrel body are prone to misalignment, which can cause the cover to fail, and the bucket hoop needs to be adjusted again, which affects the work efficiency and is not conducive to automatic production.
