An automatic unpacking device for cement bags

Abstract

The invention relates to an automatic unpacking device for cement bags, which effectively solves the problem that cement is easy to remain in the packaging bag and the packaging bag cannot be automatically sorted; The rotating shafts can rotate in opposite directions synchronously; there is a blade in the middle of the two rotating shafts, and there is an L-shaped rod on the rotating shaft. The L-shaped rod is composed of a long rod and a short rod. On the bag; the left and right sides of the casing are the first door panels whose lower ends are hinged on the casing, the two first door panels can rotate outward respectively, and the first door panels are inserted with movable rods, and the movable rods on the two first door panels are symmetrical And can move left and right; two movable rods are placed between the front and rear L-shaped rods, and placed above the rotating shaft; the invention solves the problem that cement is easy to remain in the packaging bag and the packaging bag cannot be automatically arranged, and the cement in the bag is completely Pour out clean without residue, and can collect and organize the packaging bags.

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...
