A push-type can compression device based on negative pressure contraction

Abstract

The invention discloses a press-type can compression device based on negative pressure contraction, and relates to the technical field of waste product recovery. The push-type can compression device based on negative pressure shrinkage includes a negative pressure mechanism, the inner wall of the negative pressure mechanism is slidably connected with a diversion rotating mechanism, and the surface top of the diversion rotating mechanism is fixedly connected with a limit mechanism through a bearing, and the limit mechanism The bottom of the bottom is fixedly connected with the upper surface of the negative pressure mechanism, and the top of the surface of the diversion rotating mechanism is fixedly connected with a support frame. The press-type can compression device based on negative pressure shrinkage, through the piston ring, draws the gas in the can into the negative pressure housing, causing the can to shrink inward, thereby preventing the can from expanding sideways when the can is compressed, resulting in a compressed can Edges and corners are generated. When the compressed pop cans are packed in woven bags, the corners are easy to scratch the woven bag, resulting in damage to the woven bag. The compressed pop cans cannot be bagged, which is inconvenient for transportation.

Description

technical field [0001] The invention relates to the technical field of waste product recycling, in particular to a press type can compression device based on negative pressure contraction. Background technique [0002] At present, when recycling used cans, the cans are usually first flattened to reduce the space occupied by the cans. However, during the extrusion process, the upper and lower ends are misaligned, causing the cans to expand sideways, resulting in edges and corners. When the compressed cans are packed in bags, the edges and corners generated by the compression of the cans are easy to scratch the woven bag, causing the cans to leak from the inside of the woven bag, making it inconvenient to collect and transport the compressed cans. [0003] Such as Chinese patent announcement number is that CN207310605U discloses a pop can crushing device, pop cans are placed in the compression sleeve, and then step on or press the pedal to make the compression plug flatten the...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a press-type can compression device based on negative pressure contraction, which solves the problem that the upper and lower ends of the can are misaligned during the extrusion process, causing the can to expand sideways and produce edges and corners. When the compressed cans are packed in woven bags, the edges and corners produced by the compression of the cans are easy to scratch the woven bag, causing the cans to leak from the inside of the woven bag, making it inconvenient to collect and transport the compressed cans
