Cigarette packet conveying channel capable of separating and detecting packet cover on line of hard packet packer

Abstract

The invention relates to a device in a hard cigarette packet packer, in particular to a cigarette packet conveying channel capable of separating and detecting a packet cover on line of a hard packet packer. The cigarette packet conveying channel comprises a supporting bridge, a baffle and a conveying belt, wherein a packet cover separation device and a detection device are mounted on the cigarette packet conveying channel; the packet cover separation device comprises two pairs of differential transmission rollers and a transmission mechanism for driving the differential transmission rollers to rotate along the conveying direction of the conveying belt; the two pairs of differential transmission rollers are symmetrically arranged on two sides of the conveying belt; each pair of differential transmission rollers comprises a slow conveying roller and a fast conveying roller which are distributed in sequence along the conveying direction of the conveying belt; and the detection device comprises two groups of laser correlation type photoelectric switches which are arranged in sequence along the conveying direction of the conveying belt. The cigarette packet conveying channel can separate the packet cover from a drawing type flip hard cigarette packet conveyed on the conveying channel and automatically detect whether the packet cover is separated to a proper distance.

Description

technical field [0001] The invention relates to a device in a cigarette hard box packaging machine, in particular to a cigarette packet conveying channel of the hard box packaging machine. Background technique [0002] The ZB45 packaging unit is a GDX2 model introduced by China Tobacco Import and Export Corporation from Italy G.D Company, and handed over to Shanghai Tobacco Industrial Machinery Factory for localization. Among them, the YB45 hard box packaging machine is its main part, and the production capacity of this model is Up to 400 packs / minute, stable performance, high production efficiency, widely used in various cigarette manufacturers. [0003] With the development of tobacco products, a small liftable clamshell box rigid packaging came into being. The traditional packaging methods including the ZB45 rigid box packaging machine can no longer meet the requirements of this packaging. The technical solution with the patent application number of 2017100939457.5 is an...

Problems solved by technology

[0004] In the actual production process, due to the cutting of the integral label paper without cutting the bottom, there may be a phenomenon that the label paper sticks to each other, or the phenomenon that the pull tab slides out of the paper jam slot of the inner frame, the former will cause the box cover to not be pulled out The lid cannot be opened due to separation, which will make the pull-opening of the lid less smooth

At present, on the production line, the liftable flip-top hard packs with these quality defects still need to be manually inspected, screened and eliminated, which is inefficient and labor-intensive
