Case unpacking mechanism for case unpacking machine

Abstract

The invention provides a case unpacking mechanism for a case unpacking machine. The case unpacking mechanism comprises an upright, a guide rail, a sliding block, a long folding sheet, a short folding sheet and a lifting mechanism, wherein the guide rail is arranged on the upright, the sliding block is arranged on the guide rail in a sliding mode, the long folding sheet and the short folding sheet are arranged on the sliding block, and the lifting mechanism controls lifting of the sliding block. A connecting rod angle changing assembly is arranged between the long folding sheet and the short folding sheet and driven by a case unpacking air cylinder, the long folding sheet and the short folding sheet are respectively provided with a plurality of pin installation bases arranged side by side, pins are installed on the pin installation bases, and guide bases are arranged in the directions of the pins. By the adoption of the technical scheme, automatic case unpacking, namely, flattening of paper cases, can be achieved, the stability and the continuity of case unpacking are improved, the rate of good products is increased, the working efficiency is improved, and the cost is reduced.

Description

technical field [0001] The invention relates to the field of packaging and unpacking machines, in particular to an unpacking mechanism for the unpacking machine. Background technique [0002] At present, most of the unpacking mechanisms of the unpacking machines in the same industry in the market use cylinders to push materials to push the flattened cartons forward, and then the front end uses the mechanism of the cylinder to control the suction cups to unpack, but the unpacking mechanism of the cylinders to control the suction cups is due to The air pressure is not constant and the adsorption force of the lip of the suction cup on the carton is different, which will lead to a low yield rate during the unpacking process of the suction cup and affect the stability of the unpacking mechanism. Contents of the invention [0003] In order to overcome the deficiencies in the existing equipment technology, the object of the present invention is to provide an unpacking mechanism f...
