Feeding device with bag insertion function

Abstract

The invention relates to a feeding device with the bag insertion function. The feeding device comprises a feeding pipe, a bag grabbing mechanism capable of conducting axial stretching along a feeding pipe is arranged on the exterior of the front end of the feeding pipe, the bag grabbing mechanism is used for being inserted into a valve opening of a valve opening bag and grabbing the valve opening bag when being stretched out, and used for bringing back the valve opening bag when being drawn back, and the front end of the feeding pipe is exposed out so that a feeding opening is located in the center of the upper portion of the valve opening bag. The feeding device is suitable for packaging various kinds of powder such as mineral powder, cement, edible powder and various kinds of chemical powder with the valve opening bag. When the feeding device is used for packaging the powder through the valve opening bag, bag insertion is not needed any more, only the valve opening bag needs to be tidied and positioned, then the bag grabbing mechanism of the feeding device automatically grabs the valve opening bag and enables the valve opening bag to be arranged on the feeding pipe in a sleeved mode, and the bag insertion function in the prior art is achieved. By means of the technical scheme, the feeding device is unique in idea, ingenious in conception, simple in structure, low in manufacturing cost, simple, practical, high in production efficiency, particularly convenient to maintain and quite suitable for packaging the powder with the valve opening bag inland.

Description

technical field [0001] The invention relates to packaging machinery, in particular to equipment for packaging powder in valve pockets, more specifically to a feeding device for packaging powder in valve pockets, especially a feeding device with the function of inserting bags. Background technique [0002] Powder packaging generally uses valve pockets to prevent powder from spraying out when filling powder. The valve bag is a popular packaging bag in the world at present. It feeds from the top or bottom valve port. It adopts special filling equipment. After filling the material, it is packed into a cube. The stacking is neat and beautiful. According to the material, valve bags can be divided into: pp valve bags, PE valve bags, paper-plastic composite valve bags, kraft paper valve bags and multi-layer kraft paper valve bags. The valve bag is mainly used for packaging food powder, chemical powder, fertilizer, synthetic materials, grain, salt, minerals and other powdery or gran...
