Crushing assembly and crusher comprising same

Abstract

The invention relates to a crushing assembly. The crushing assembly comprises a first tool, a second tool and a rotary shaft. The first tool and the second tool are arranged on the rotary shaft. The first tool is fixed relative to the rotary shaft. The second tool can swing relative to the rotary shaft. According to the crushing assembly, the first tool is driven to rotate by the rotary shaft so that a plastic shell and other materials can be shredded, and the materials are broken into pieces by the second tool swinging relative to the rotary shaft. By adopting the mode that the first tool and the second tool are combined, tool abrasion is reduced, quick crushing of complex plastic containing screws and other metal impurities is achieved, the metal separation pretreatment procedure is omitted, the production cost is reduced, and the production efficiency is improved. The invention further relates to a crusher comprising the crushing assembly.

Description

technical field [0001] The invention relates to the field of garbage crushing, in particular to a crushing assembly and a crusher including the crushing assembly. Background technique [0002] With the wide application of plastics in daily life, the amount of plastic waste is increasing, and the recycling and reuse of plastic waste is becoming more and more important, among which the recycling of plastic shells of home appliances is particularly important. At present, there are two main types of crushing equipment for plastic casings of household appliances. One is the blade-cutting crusher, the blade is fixed on the main shaft and the body, and the plastic is cut through the operation of the main shaft. This type of equipment is low in price and is mainly used for crushing pure plastics such as beverage bottles, and for crushing belts such as TV sets. Household appliance casings with metal such as screws are likely to cause wear on the cutting edge and reduce production ef...

Problems solved by technology

One is the blade-cutting crusher, the blade is fixed on the main shaft and the body, and the plastic is cut through the operation of the main shaft. This type of equipment is low in price and is mainly used for crushing pure plastics such as beverage bottles, and for crushing belts such as TV sets. Home appliance shells with metal such as screws are likely to cause wear on the cutting edge and reduce production efficiency

The other is the four-shaft crusher, which can crush and crush materials containing metal and other materials such as refrigerators through four-axis operation. However, this type of equipment is expensive and consumes a lot of energy. It is used for crushing household appliances. Plastic casing will undoubtedly increase the cost of crushing and reduce production efficiency
