Continuous-packaging packaging bag folding mechanism and folding method

Abstract

The invention discloses a continuous-packaging packaging bag folding mechanism. The mechanism comprises a first folding conveyor belt and a second folding conveyor belt; a conveying surface of the second folding conveyor belt is lower than a conveying surface of the first folding conveyor belt; the second folding conveyor belt can realize forward or backward conveying; and a continuous-packaging packaging bag is conveyed by the first folding conveyor belt to the second folding conveyor belt, and is folded by forward or backward conveying by the second folding conveyor belt. According to the folding mechanism, through the combination of the two conveyor belts, folding operation of the continuous-packaging packaging bag can be realized under simple combined actions, the folding speed is fast, and the cost is low. According to a folding method, a pause step is added to ensure flatness of the packaging bag, the situation of non-flat folding caused by inertia is prevented, and through same-speed transmission and synchronous pause of the first folding conveyor belt and the second folding conveyor belt which are matched with each other, folding effect of the packaging bag is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of packaging equipment, and in particular relates to a folding mechanism for multipack packaging bags and a method for folding packaging bags using the mechanism. Background technique [0002] In the packaging industry, many products (such as food, medicine, etc.) are packaged in bags. In the actual production of products, in order to obtain higher production efficiency, the action of product bagging has multiple stations. At the same time, so most of the packaging after bagging is a continuous package structure. In one case, it needs to go through sub-packaging operations. In another case, when some products are packed into the packaging box, they are multi-packages (consecutive packages). of; [0003] When packing (boxing) multi-pack products, it is necessary to fold the packs so that each product bag in the packs is stacked in sequence, and then packed. In the prior art, the process of stacking packs is ...

Problems solved by technology

[0003] When packing (boxing) multi-pack products, it is necessary to fold the packs so that each product bag in the packs is stacked in sequence, and then packed. In the prior art, the process of stacking packs is manually operated, but It is foreseeable that the manual folding and packaging method has low folding efficiency and wastes manpower, and the manual operation station reduces the degree of automation, which is not conducive to assembly line operations and affects packaging efficiency to a large extent; the second is to use Automatic folding methods such as manipulators, the way of manipulators, the cost of equipment is relatively high, and its folding efficiency is not as good as manual operation
