Full-automatic bale breaker

Technical Field

The invention relates to the technical field of unpacking devices, in particular to a full-automatic unpacking machine.

Background

At present, in the packing field, the raw materials that the product was packed in the blowing is mostly the resin particle principle, and to the multi-purpose 100 kilograms plastic bag packing of resin particle, in use needs artifical broken bag and reinforced, because the resin particle raw materials that need at every turn are more, so traditional this kind of mode just has the problem of manual operation inefficiency and safe risk. Chinese patent discloses some automatic unpacking equipment, such as a fully automatic big process unpacking machine, application No. 2016210076251, which comprises a frame, a lifting mechanism, a movable grid medium sensing mechanism, a material grabbing mechanism, a traveling mechanism, a bag breaking mechanism, a vibrating mechanism and a waste bag processing mechanism, the concrete structure of the material grabbing mechanism is not disclosed, but only the fact that the air cylinder drives the rotating shaft to rotate is explained, the rotating shaft fixes the grippers, how to grab the packaging bags by the specific grippers is not written, whether the packaging bags are grabbed firmly or not is directly related to the subsequent work, in addition, the structure directly arranges the waste bag processing mechanism at the front side of the rack, the bag breaking mechanism is arranged on the rear side of the waste bag processing mechanism, the waste bag processing mechanism only shows that the shifting fork is driven to rotate by the driving cylinder, and how the shifting fork pulls the waste bag down for processing is not shown, so that the integral structure of the patent is quite unclear. In addition, the Chinese patent also discloses a full-automatic high-speed unstacking and unpacking machine, application number 201720928462.9, the structure of which is basically the same as that of the first comparison document, but the specific structure of a grabbing mechanism is disclosed, the grabbing structure is too complex, the structure can not grab large-area and large-volume packaging bags at all, the surfaces of the packaging bags per se are very smooth, a grab hand can not grab the packaging bags firmly at all, in addition, the structure is provided with devices for automatically shaking the belt and pushing the bags, the structure is very complex, and thirdly, only the upper layer can be unpacked at each time, and the working efficiency is lower.
