Description

TECHNICAL FIELD

[0001] The application relates to the technical field of iron wire removing, in particular to an intelligent iron wire removing method for PET bottle bricks. BACKGROUND

[0002] Due to the light weight, good preservability, heat resistance and pressure resistance of PET bottles, the PET bottles have been widely applied to many fields such as beverage packaging, food, chemical industry and medicine, and with the development of economy, the market demand for the PET bottles is also increasing year by year. When the materials are discarded, many problems such as environmental pollution are also faced. The PET bottles belong to recyclable materials, and recycling the PET bottles not only realizes the reuse of resources, but also reduces the pollution to the environment.

[0003] In the recycling process, in order to facilitate storage and transportation, a hydraulic packing machine is usually used to compress and reduce the volume of the PET bottles. When the PET bottles are extruded to a certain volume, the dispersed PET bottles are formed into bottle bricks through iron wire bundling.

[0004] In the PET bottle cleaning and recycling industry, the PET bottles need to be sequentially broken, cleaned and dried. The prerequisite for realizing this series of production processes is to unpack and scatter the PET bottle bricks. The known unpacking and scattering method is to manually cut the iron wire, pull it out, and then transport the PET bottle bricks from which the iron wire is removed to a unpacking machine to scatter the PET bottle bricks by the unpacking machine. Since the PET bottle bricks are formed through iron wire bundling after being extruded by the hydraulic packing machine, in the process of cutting the iron wire, the iron wire may burst, the PET bottles may scatter and the like, which is harmful to the surrounding operators. The scattered PET bottles also need to be cleaned by the operators from time to time, which affects the working environment and increases the work burden of the operators.
