Smashing device used for copper wire granulator

Abstract

The invention discloses a smashing device used for a copper wire granulator. The smashing device comprises a machine frame, wherein three mounting grooves are formed in the machine frame, both ends of the machine frame are provided with bearing frames in a screw joint manner by means of fastening bolts, each bearing frame is provided with bearings at corresponding positions of the mounting grooves, the bearing in the middle is provided with a main hob, the bearings at two sides are provided with auxiliary hobs, each auxiliary hob is provided with annular hob blades in an array, hob grooves matched with the annular hob blades are formed in the mounting grooves, a mounting shaft of the main hob is provided with hob blades and a wire shifting board, and a V-shaped cutting edge is integrally formed on the upper end of each hob blade. Through improving bare single-row hobs of a smashing device of an original copper wire granulator into a two-side auxiliary blade closed mode, the smashing device effectively solves the problem that cables are clamped between cracks of cutters and cannot be cut effectively, and the additionally arranged wire shifting board can effectively drive the cables which are not completely cut to continue to participate in cutting.

Description

technical field [0001] The invention relates to the technical field of metal crushing, in particular to a crushing device for a copper rice machine. Background technique [0002] With the rapid development of our country and the world's social economy, the production and consumption of cables has become the second largest industry in China after the automobile industry. The rapid development of the wire and cable industry will inevitably lead to the elimination of a large number of waste wires and cables. The composition includes metal conductors, insulators and covering protective layers. The main materials of insulators and protective layers are polyvinyl chloride, polyethylene, fluororesin, neoprene, chlorosulfonated polyethylene and other halogen-containing materials. Due to the annual The amount of use is huge, and it contains a lot of recyclable resources, so it is of great significance for the recycling of waste cables. The copper rice machine is currently the main eq...

[0002] With the rapid development of our country and the world's social economy, the production and consumption of cables has become the second largest industry in China after the automobile industry. The rapid development of the wire and cable industry will inevitably lead to the elimination of a large number of waste wires and cables. The composition includes metal conductors, insulators and covering protective layers. The main materials of insulators and protective layers are polyvinyl chloride, polyethylene, fluororesin, neoprene, chlorosulfonated polyethylene and other halogen-containing materials. Due to the annual The amount of use is huge, and it contains a lot of recyclable resources, so it is of great significance for the recycling of waste cables. The copper rice machine is currently the main equipment for recycling cables. It separates and processes the cables into copper rice, and the processed copper rice can be used directly. , in the existing copper rice machine, it is necessary to crush the cable into copper rice through the crushing device first, and peel off the protective layer outside the copper wire. The existing copper rice machine crushing equipment has low efficiency of processing copper rice and protects The removal rate of layers is not high, mainly because the existing equipment mainly uses single-row straight-tooth cutters, so the cutting of cables is not sufficient, and the single-row hobs of the original copper rice machine are all exposed in the frame. When actually cutting copper rice, the cable is easy to get stuck in the cutting gap and cannot be effectively cut off. If a new type of equipment that can effectively improve the cutting efficiency and the removal rate of the protective layer can be invented, this kind of problem can be solved. For this reason, we provide a crushing device for copper rice machine
