Packaging bag opening mechanism

Abstract

The invention provides a packaging bag opening mechanism which can be used for opening mouths of packaging bags so as to be convenient for filling and is applicable to paper packaging bags. The packaging bag opening mechanism comprises a paper collecting plate, a paper sucking plate, two paper sucking plate guide columns, a bag collecting base bottom plate and an inner bag lifting servo motor, wherein both the paper collecting plate and the paper sucking plate are provided with vacuum air suction systems, the front sides of the paper collecting plate and the paper sucking plate are vertically oppositely arranged. Each vacuum air suction system comprises a mesh type air suction port, a vacuum bottom plate, a vacuum pipe and a vacuum pump. Both the paper collecting plate and the paper sucking plate are of hollow structures. The mesh type air suction ports and the vacuum bottom plates are mounted on two sides of the hollow structures, the mesh type suction ports are respectively arranged on the front sides of the paper sucking plate and the paper collecting plate, the vacuum bottom plates are respectively assembled on the back sides of the paper sucking plate and the paper collecting plate and are communicated with the vacuum pipes, the vacuum pipes are connected with the vacuum pumps, and the paper sucking plate is sleeved on the two paper sucking plate guide columns.

Description

Technical field: [0001] The invention relates to an opening mechanism for a packaging paper bag, which belongs to the technical field of packaging equipment. Background technique: [0002] At present, in the packaging line, it is often necessary to remove the packaging paper bag from the conveying mechanism, put it on the line correctly, and then open the paper bag to facilitate the insertion of particulate matter. [0003] In the existing packaging production line, the opening of the opening of the packaging bag is either manually operated or automatically opened by corresponding equipment. However, the design of the existing mechanism and equipment is not clever enough. Sometimes it is not convenient to open the opening of the bag. It is necessary to design The new opening mechanism and the existing devices are all designed for a product of a certain specification. Invention content: [0004] According to the state of the art, the present invention provides an opening m...
