Bag clamping conveying mechanism and bag clamping conveying method

Abstract

The invention discloses a bag clamping conveying mechanism and a bag clamping conveying method. The bag clamping conveying mechanism comprises a rack, a conveying mechanism and clamping hand assemblies arranged on the conveying mechanism and used for conveying bags, wherein the conveying mechanism comprises a chain wheel, a chain and a chain wheel driving motor used for driving the chain wheel to rotate, the clamping hand assemblies comprise the A-type clamping hand assemblies and the B-type clamping hand assemblies, one or more A-type clamping hand assemblies form a group, one or more B-type clamping hand assemblies form a group, the number of the A-type clamping hand assemblies in each group is the same as the number of the B-type clamping hand assemblies in each group, and with the group as a unit, the A-type clamping hand assemblies and the B-type clamping hand assemblies are arranged at intervals. According to the bag clamping conveying mechanism and the bag clamping conveying method, packaging bags can be continuously and quickly conveyed, so that a packaging machine can achieve a faster working speed, and the working efficiency is greatly improved; and the distance between clamping hands of the hand clamping assemblies is adjusted through the control of a guide rail mechanism, actions such as bag opening and bag closing are completed, and the overall structure is compact.

Description

technical field [0001] The invention relates to the technical field of packaging machinery, in particular to a bag-clamping transmission mechanism and a bag-clamping transmission method. Background technique [0002] In the field of packaging machines, especially in horizontal packaging machines, bags need to be conveyed between each station. Most of the bag transmission mechanisms in existing horizontal packaging machines are fixed and moved by two layers of multiple clips, through different The opening and closing sequence and the movement of the mobile clip are used to realize the bag transmission. Due to the limitation of the structure, this kind of transmission is mostly linear, and the bag can only be transmitted in a straight line for a certain distance. Due to the range of motion and the weight of the clip itself, it cannot reach too high. The transmission speed is high, and the distance between the clips is fixed when working. When it is necessary to change bags of ...

[0002] In the field of packaging machines, especially in horizontal packaging machines, bags need to be conveyed between each station. Most of the bag transmission mechanisms in existing horizontal packaging machines are fixed and moved by two layers of multiple clips, through different The opening and closing sequence and the movement of the mobile clip are used to realize the bag transmission. Due to the limitation of the structure, this kind of transmission is mostly linear, and the bag can only be transmitted in a straight line for a certain distance. Due to the range of motion and the weight of the clip itself, it cannot reach too high. The transmission speed is high, and the distance between the clips is fixed when working. When it is necessary to change bags of other widths, it is necessary to loosen the bolts, adjust the distance, and then tighten them. The time is long, the efficiency is low, and the device takes up the effective work of the bag. The space is relatively large, which affects the realization of other application functions, such as limited coding positions, etc.
