Container forming device for filling machine

Abstract

The invention relates to a container forming device for a filling machine, comprising container supports and paired movable parts, wherein the container supports are respectively arranged on sealing pliers and reverse sealing pliers which are paired, and the paired movable parts are arranged on the paired sealing pliers and the reverse sealing pliers and used for pulling a packing material tubes; the container supports are in a flat plate shape, and forming plates are fixed on the movable part; and the forming plates and the container supports form a forming cavity surrounding the rectangular section of the packaging material tube under the state that the movable parts pull the packaging material tube. Therefore, four sides of the packaged container are respectively folded and formed by the container supports and the forming plates from the four sides, folding lines at the four corners of the container supports and the forming plates correspond to the four corners of the packaged container, i.e. four knuckle lines correspond to the folding lines of the forming plates; and since the knuckle line parts of the packaged material are prepressed with crease lines, the knuckle parts cangenerate regular deformations and can not be squeezed into the folding lines in the extrusion process of the packaging material tube.

Description

technical field [0001] The present invention relates to a filling machine, in particular to a container forming device for the filling machine. Through the forming device, the filling machine forms the cylinder formed by the packaging strip into a single one, the cross section of which is approximately Rectangular packing container. Background technique [0002] At present, most of the milk and beverages we drink often use aseptic packaging containers. The packaging container can isolate light, oxygen in the air, and the entry of foreign bacteria, so that the packaged product can be stored at ambient temperature for a long time without spoiling. Common such packaging containers on the market include pillow bags, brick bags, roof bags, diamond bags, etc. Among them, the hexahedral brick bags are more popular among consumers because of their beautiful appearance, easy placement, and convenient use. [0003] Brick packs are made in filling machines. In the filling machine, t...

Problems solved by technology

This container forming device has the following disadvantages: the cross-section of a single capacity holder is U-shaped, and the gap between the paired capacity holders is in the middle of the side of the container after they are engaged with each other. During the process, when a single packaging container is squeezed, the gap between the capacity holder will inevitably pinch the side of the cylinder
