Background
In the field of application of solid material crushing treatment technologies, such as a jaw bag breaker and a counter-impact bag breaker in a mine bag breaker, the crushing device is specially applied to crushing of hard and brittle materials so as to obtain smaller and uniform-sized materials (such as crushing of materials such as stones and coal mines); the common shearing type bag breaking machine is applied to breaking materials with high flexibility and toughness so as to obtain smaller and uniform-size materials (such as breaking of materials such as rubber, iron sheets and cloth). In daily urban solid waste, plastic bags are mainly used as packages for garbage waste, such as household kitchen waste, restaurant garbage bags, bagged waste generated in the currently prevailing takeaway industry and the like, and for the bagged waste, the garbage bags need to be broken first to meet the garbage classification process of subsequent treatment and the like. The plastic bag of bagged wastes belongs to materials with general flexibility and toughness, and obviously, the conventional mine bag breaking machine can not meet the treatment requirement; although the shearing type bag breaking machine can break or break the materials, the shearing type bag breaking machine can also break garbage in the bag when working, and the subsequent process is influenced.
The current bag breakers in the market have single-sided shear bag breakers and blade-spaced bag breakers. The unilateral shearing type bag breaking machine is transformed from an original shearing type crusher, only a bag can be cut into two parts, and materials in the bag can be damaged or the bag cannot be completely broken, so that the materials cannot be fully separated and dispersed from the bag. The blade interval type bag breaking machine does not shear materials, only breaks bags by means of differential speed of two shafts, the plastic bags slide down and pass through too fast, the plastic bags can only be punctured, the bag breaking rate is low, and the bag breaking effect is poor. In summary, the bag-breaking machine described above has application defects or needs manual intervention after bag-breaking and discharging, and needs to shake off the materials in the bag in a half-bag-breaking state, which increases unnecessary processing procedures.
