Description

Wrapping bag inserting mechanism

Technical Field

The utility model belongs to the technical field of packaging machinery, concretely relates to wrapping bag slash pocket mechanism.

Background

In the industrial production process, a large amount of solid granular or powdery materials need to be packaged by packaging bags and then transported. Before the packaging of materials is carried out, the packaging bag conveying belt needs to be assigned to a charging station, then the packaging bag is lost through a special device, then the packaging bag is opened through a special bag opening device, and then the opened packaging bag is conveyed to a specific position to be filled, and then the subsequent packaging or conveying work can be continued. The existing bag taking mechanism, bag opening mechanism and bag conveying mechanism are often mutually independent structures, and generally occupy larger space and have more redundant structures; and the bag opening mechanism performs bag opening work through mutually independent mechanisms, so that the synchronism of the bag opening work is not easy to guarantee, and the working efficiency is not high enough.

Most of the existing bag opening mechanisms are provided with suckers on two sides of a packaging bag, the suckers are mounted on a rack, and the suckers on two sides of the packaging bag are driven by a gear and rack to move close to or away from the side face of the packaging bag, so that the packaging bag is opened. However, the conventional bag opening device has the problems of large stroke and large occupied space. Meanwhile, the synchronism of the bag opening mechanisms positioned on the two sides of the packaging bag is difficult to unify, and the problem that the packaging bag falls off can be caused.

The existing bag conveying mechanism mostly adopts belt transmission or adopts parts such as oil cylinders and air cylinders to carry out linear transportation, occupies a large space, and in a working environment with heavy dust, the service lives of the linear transportation parts such as the oil cylinders and the air cylinders can be greatly reduced, and meanwhile, the use and maintenance costs of the belt groups, the oil cylinders and the air cylinders are relatively high.

Consequently, to get in traditional wrapping bag slash pocket mechanism the bagging apparatus, open the bagging apparatus, send the redundant structure that the bagging apparatus exists many, the structure is complicated, get the bag and open the bag and send the bag synchronism low, the wrapping bag removes the in-process and drops easily, the relatively higher problem of maintenance cost, the utility model discloses a wrapping bag is opened and is sent a bag mechanism.
