Automatic cement bag unpacking device

Abstract

The invention relates to an automatic cement bag unpacking device which effectively solves the problems that cement is prone to remaining in a packing bag, and the packing bag cannot be automaticallyarranged. According to the technical scheme, the automatic cement bag unpacking device comprises a shell, two rotating shafts are inserted into the shell, and the two rotating shafts can synchronouslyand reversely rotate; a blade is arranged between the two rotating shafts, L-shaped rods are arranged on the rotating shafts, each L-shaped rod is composed of a long rod and a short rod, and when thetwo rotating shafts synchronously rotate towards the middle, the short rods on the L-shaped rods can be inserted into the packaging bag; first door plates with the lower ends hinged to the shell arearranged at the left side and the right side of the shell, the two first door plates can rotate outwards respectively, movable rods are inserted into the first door plates, and the movable rods on thetwo first door plates are in bilateral symmetry and can move leftwards and rightwards; and the two movable rods are arranged between the front L-shaped rod and the rear L-shaped rod and are arrangedabove the rotating shafts. The automatic cement bag unpacking device solves the problems that the cement is prone to remaining in the packaging bag and the packaging bag cannot be automatically arranged, the cement in the packaging bag can be completely poured out without residues, and the packaging bag can be collected and arranged.

Description

technical field [0001] The invention relates to the field of building construction, in particular to an automatic unpacking device for cement bags. Background technique [0002] A large amount of cement is often used in the process of building construction. Cement is usually packed in single-layer bags, and some high-end cement is also packed in inner bags containing plastic films. The inner bag is set with a strong outer bag; During the production process, the packaging bag needs to be dismantled and the cement poured out; generally, the packaging bag is cut manually with a knife when unpacking, and the cement in the packaging bag is poured out by shaking the bag manually after the bag is cut. This method is not only inefficient, but also requires a lot of labor, and it is necessary to cut multiple openings on the bag, which will cause the debris of the packaging bag to enter the cement. At the same time, after the cement escapes into the air, it is easy to cause dust pollu...
