Flexible turning-around device for small cigarette packets

Abstract

The invention provides a flexible turning-around device for small cigarette packets. The flexible turning-around device for the small cigarette packets comprises a speed control unit, a packet distributing unit and a reversing unit. The speed control unit comprises two sets of plane conveying belts which are arranged up and down and rotate relatively; a cigarette packet conveying channel is formedbetween the plane conveying belts; the packet distributing unit comprises two sets of harrow conveying belts which rotate oppositely; the two sets of harrow conveying belts are arranged left and right; a cigarette packet subpackaging conveying channel is formed between the two sets of harrow conveying belts; the distance between every two adjacent harrows on the same harrow conveying belt is larger than the length of a cigarette packet. an outlet of the cigarette packet conveying channel is connected with an inlet of the cigarette packet subpackaging conveying channel; a cigarette packet accelerating mechanism is mounted at the joint; the reversing unit comprises a reversing conveying belt and a sliding table; the conveying direction of the reversing conveying belt is perpendicular to thecigarette packet subpackaging conveying channel; the reversing conveying belt is provided with an anti-springback mechanism and a flexible collision table; and a plurality of push plates are evenly distributed on the reversing conveying belt. The device has the advantages of controlling the cigarette packet supply speed and quantity and preventing cigarettes from being damaged due to overspeed cigarette collision.

Description

technical field [0001] The invention relates to the tobacco industry, in particular to a flexible U-turn device for cigarette packets. Background technique [0002] After the cigarette packs are made into small packs, they enter the channel from the main machine and are transported to the small pack transparent paper packaging machine by the channel. The channel is usually transported by a conveyor belt. Generally, at least one change of direction is required. [0003] In some occasions, in order to meet the packaging requirements of the subsequent packaging machine, the filter end or tobacco end of the cigarette pack is required to be conveyed forward, and the current conveyor is often at a high speed for efficiency. At the reversing conveyor belt, it will be installed A stopped end face, when the cigarette package hits the end face, it will fall onto the reversing conveyor belt, and then be transported to the packaging machine by the reversing conveyor belt. [0004] Ther...

Problems solved by technology

[0005] First, when the cigarette package hits, if the filter tip is facing forward, the tobacco at the tobacco end will be compressed due to inertia, resulting in a cavity at the end; when the tobacco end is facing forward, the tobacco at the tobacco end will leak out due to inertia, causing quality problems

[0006] Second, because the speed of the conveyor belt is always fast, the cigarette packets are backlogged at the reversing conveyor belt. The current solution is to install a lifting mechanism at the reversing conveyor belt to lift only one pack of cigarettes at a time. A pack of cigarettes is pushed onto the conveyor belt of the packaging machine, which is awkward
