A foot-opening mechanism in an automatic packaging machine for flat-bottomed bags

Abstract

The invention discloses a foot opening mechanism in a fully-automatic packing machine for flat-bottom bags. The foot opening mechanism comprises a support, and is characterized in that two fixing seats and two guiding seats which are arranged in parallel are distributed on the end surface of one end of the support; a guiding optical shaft is mounted between the fixing seats; a lifting optical shaft is mounted between the guiding seats; a cylinder head connection plate is mounted on the lifting optical shaft and the guiding optical shaft in a guiding and matching manner and driven by a foot opening cylinder below the cylinder head connection plate; a clamping block is mounted at the end part of the lifting optical shaft; a bag opening plate frame is rotationally mounted on the clamping block through rotation pins; a bag opening plate is mounted at the upper end of the bag opening plate frame; and the middle part of the bag opening plate frame is connected with the clamping block through a tension spring. The foot opening mechanism is reasonable in structural design; the cylinder drives the bag opening plate to hook the flat bottom of a paper bag, and by the aid of the positive pressure air blowing action, the paper bag is opened completely; and the requirements for producing fully-automatic packing machines are met.

Description

Technical field [0001] The invention relates to a foot opening mechanism, in particular to a foot opening mechanism in a flat-bottom bag full-automatic packaging machine. Background technique [0002] At present, with the improvement of people's awareness of environmental protection and the importance of food safety and hygiene, flat-bottomed paper bags with beautiful appearance, easy placement, good air permeability, environmental protection and sanitation have become the development trend of packaging. Flat-bottomed paper bags can no longer meet the urgent needs of market development by manual or semi-automatic packaging. [0003] In the process of fully automatic packaging machinery, in order to facilitate the filling, the packaging bag needs to be automatically opened. In order to facilitate its assembly line operation, a foot opening mechanism is required to assist the opening of the packaging bag. The traditional way to open the packaging bag is mostly The opening mechanism ...

Manual or semi-automatic packaging of flat bottom paper bags can no longer meet the urgent needs of market development

[0003] In the process of fully automatic packaging machinery, in order to facilitate loading, it is necessary to automatically open the packaging bag. In order to facilitate its assembly line operation, a foot opening mechanism is needed to assist the opening of the packaging bag. The traditional way to open the packaging bag is mostly The mechanism is opened by opening the bag on the upper mouth of the gas. Due to the limited gas supply, there is no opening mechanism at the bottom, so it is difficult to ensure that the packaging bag is completely opened.
