Bag breaking device and domestic waste sorting line with it

Abstract

The invention discloses a bag breaking device and a domestic garbage sorting line with the same. The bag breaking device comprises a supporting frame, and a scraper machine and a bag breaking mechanism that cooperates with the scraper to form a differential to shear broken bags are disposed on the supporting frame; the bag breaking mechanism is provided with a corresponding first driver, and the first driver drives the bag breaking mechanism to swing back and forth through an eccentric mechanism; and the scraper includes a second driver and a conveyor belt, and the second driver drives the conveyor belt and materials to be separated on the conveyor belt to be delivered online. According to the bag breaking device and the domestic garbage sorting line with the same, the blade teeth of the bag breaking device is driven to swing back and forth under the action of the eccentric mechanism, and a differential movement is formed between the blade teeth of the bag breaking device and the scraper; the differential movement is used to achieve the effect of tearing and cutting the broken bags, and the efficiency of the bag breaking is improved; in addition, the blade teeth of the bag breakingmechanism are driven by the eccentric mechanism during the cutting process, the change of the cutting angle during the bag breaking process helps to reduce the wear of blades of the bag breaking mechanism, and the reciprocating swing cutting process greatly reduces the problems of material blocking and material winding in the bag breaking process.

Description

technical field [0001] The invention relates to the field of bag breaking, in particular to a bag breaking device. In addition, the present invention also relates to a domestic waste sorting line comprising the above-mentioned bag breaking device. Background technique [0002] The bag breaking device is used in fields that require bag breaking production or processing. For example, a bag breaking device needs to be introduced during the processing and processing of primary urban domestic waste to break the bagged domestic waste and facilitate subsequent mechanical processing of domestic waste. sorting process. Most of the existing bag breaking machines adopt the hopper feeding method and the drum structure. The whole bag breaking mechanism is generally composed of a drum, a moving blade, a frame, a casing, and a power system. After entering the hopper, the bag body is cracked, broken and scattered under the high-speed rotation of the moving knife driven by the roller, and ...
