Abstract
A conveying module and a conveying device for a packing machine are provided. The conveying module for the packing machine is provided on the circulating conveyor mechanism, and includes a modular pedestal on which a telescopic linkage mechanism and at least two holding units arranged in parallel for placing packing bags are provided. Each holding unit includes left and right holding components engaged with sides of the packing bag and movable relative to each other. The telescopic linkage mechanism synchronously is configured to enable the left and right holding components to move relative to each other, so as to drive all the holding units to synchronously switch between a bag deployed attitude and a bag retracted attitude. The spacing distance of the left and right holding components in the bag deployed attitude is larger than that in the bag retracted attitude.
