Bag sucking and opening device for seam bottom valve opening bag

Abstract

The invention provides a bag sucking and opening device for a seam bottom valve opening bag. The bag sucking and opening device for the seam bottom valve opening bag comprises a rack, a bag opening sucker support, an avoiding air cylinder, a bag lifting air cylinder and a reversing connection rod. One end of the rack is hinged to a bag lifting lever, a bag lifting sucker support and a transition connection rod are hinged to the bag lifting lever, and a U shape is formed by the bag lifting sucker support and the transition connection rod. A bag lifting sucker is arranged on the bag lifting sucker support, and a bag opening air cylinder is connected to the transition connection rod. The bag opening sucker support is fixed to the bag opening air cylinder and is provided with a bag opening sucker, and the bag opening sucker is opposite to the bag lifting sucker. One end of the avoiding air cylinder is connected with the bag lifting lever, and the other end of the avoiding air cylinder is connected with the bag lifting sucker support and used for driving the bag lifting sucker support to swing. One end of the bag lifting air cylinder is hinged to the rack, and the other end of the bag lifting air cylinder is connected with the bag lifting lever and used for driving the bag lifting lever to swing to be in the vertical state from the horizontal state. One end of the reversing connection rod is hinged to the rack, and the other end of the reversing connection rod is hinged to the transition connection rod. According to the bag sucking and opening device for the seam bottom valve opening bag, bag sucking and opening of the seam bottom valve opening bag can be continuously and accurately achieved, the structure is compact and functions are reliable.

Description

technical field [0001] The invention relates to the technical field of valve pocket suction bag opening, in particular to an automatic suction bag opening device for seam bottom valve pockets. Background technique [0002] Today, seam bottom valve pockets are widely used in the product packaging of my country's cement, chemical and other powder industries due to its low cost and simple manufacturing process. However, due to the inherent disadvantage of the difficulty of opening the bag, the seam bottom valve bag seriously restricts the packaging automation of related industries. In addition, most of the related industries are high-pollution industries, which will cause irreparable damage to the body of packaging operators. Foreign related equipment is mostly aimed at sticky bottom valve pockets, which is difficult to apply and promote in a large scale. Due to the cost of packaging bags, equipment and other factors, it is difficult for domestic enterprises to quickly abandon...
