Problems solved by technology

[0006] 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

Abstract

The invention discloses a press type ring-pull can compression device and method based on negative pressure contraction, and belongs to the technical field of waste recovery. The press type ring-pullcan compression device based on negative pressure contraction comprises a negative pressure mechanism. The inner wall of the negative pressure mechanism is in sliding connection with a flow guide rotating mechanism. The top of the surface of the flow guide rotating mechanism is fixedly connected with a limiting mechanism through bearings. The bottom of the limiting mechanism is fixedly connected with the upper surface of the negative pressure mechanism. The top of the surface of the flow guide rotating mechanism is fixedly connected with a supporting frame. According to the press type ring-pull can compression device based on negative pressure contraction, through a piston ring, gas in a ring-pull can is sucked into a negative pressure shell, the ring-pull can is contracted inwards, and therefore the situation that when compressed, the ring-pull can expands towards the side face, consequently, edges and corners are generated to the compressed ring-pull can, when the compressed ring-pull can is contained in a woven bag, the woven bag is prone to being scratched by edges and corners, consequently, the woven bag is damaged, the compressed ring-pull can cannot be bagged, and transporting is inconvenient is avoided.

Description

[0001] This application is a divisional application with an application date of August 23, 2018 and an application number of CN201810963523.4, which is a push-type can compression device based on negative pressure contraction. technical field [0002] The invention relates to the technical field of waste product recycling, in particular to a compression device and method for pressing cans based on negative pressure contraction. Background technique [0003] 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 compress...
