Problems solved by technology

Manual or semi-automatic packaging of flat bottom paper bags can no longer meet the urgent needs of market development
In the process of fully automatic packaging machinery, in order to facilitate loading, the packaging bag needs to be opened automatically. The existing bag opening method is to open it by blowing gas into the packaging bag. Due to the limited air supply, the bottom of the bag is not positioned. Tooling, it is difficult to ensure that the packaging bag is completely opened

Abstract

The invention discloses a bag opening and positioning tool of a packaging machine. The tool comprises a fixed seat, a lifting mechanism fixed to the fixed seat and a bag opening clamp which is connected to the top end of the lifting mechanism and is in bilateral symmetry; the lifting mechanism comprises a lifting driving air cylinder and a lifting rod, wherein the lifting driving air cylinder is fixed to the bottom end of the fixed seat, and the lifting rod is connected with the lifting driving air cylinder; the bag opening clamp comprises a U-shaped mounting frame fixed to the top end of the lifting rod, a movable guide rail fixed to the top end of the U-shaped mounting frame, two clamping plates which are mounted on the movable guide rail in a sliding manner and provided with opposite inner end faces and a clamping plate driving air cylinder connected with the clamping plates; and the lifting driving mechanism and the clamping plate driving air cylinder are both connected with a master controller.

Description

technical field [0001] The invention relates to the field of packaging machines, in particular to a bag opening and positioning tool for the packaging machine. Background technique [0002] At present, with the improvement of people's awareness of environmental protection and the emphasis on food safety and hygiene, flat-bottomed paper bags with beautiful appearance, easy placement, good air permeability, and environmental protection and hygiene have become the trend of packaging development. Flat-bottomed paper bags can no longer meet the urgent needs of market development by manual or semi-automatic packaging. In the process of fully automatic packaging machinery, in order to facilitate loading, it is necessary to automatically open the packaging bag. The existing bag opening method is to open it by blowing gas into the packaging bag. Due to the limited gas supply, the bottom of the bag is not positioned. Tooling, it is difficult to ensure that the packaging bag is comple...
