Pressing type ring-pull can compression device based on negative pressure contraction

Abstract

The invention discloses a pressing type ring-pull compression device based on negative pressure contraction and relates to the technical field of waste recycling. The pressing type ring-pull compression device based on negative pressure contraction comprises a negative pressure mechanism. A flow guide rotating mechanism is connected to the inner wall of the negative pressure mechanism in a slidingmanner, and a limiting mechanism is fixedly connected to the top of the surface of the flow guide rotating mechanism through a bearing. The bottom of the limiting mechanism is fixedly connected withthe upper surface of the negative pressure mechanism. A supporting frame is fixedly connected to the top of the surface of the flow guide rotating mechanism. By means of the pressing type ring-pull can compression device based on negative pressure contraction, gas in a ring-pull can is extracted into a negative pressure shell through a piston ring, the ring-pull can contracts inwards, and therefore the problems that the ring-pull can is expanded laterally when being compressed, corners are generated on the compressed ring-pull can, when a woven bag is used for loading the compressed ring-pullcan, the woven bag is likely scratched by the corners, consequently, the woven bag is broken, the compressed ring-pull can cannot be bagged, and transportation is not convenient are solved.

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
