Description

FFS heavy bag edge inserting machine and edge inserting manufacturing method

Technical Field

The invention relates to the technical field of bag making, in particular to an FFS heavy bag edge inserting machine and an edge inserting manufacturing method.

Background

FFS is an integrated abbreviation for bag (Film), Fill (Fill) and Seal (Seal), and it is a high-speed packaging technology developed from europe in the early 90 s of the 20 th century, with high packaging efficiency and low cost. FFS bags are bags that are typically first made from a hose track, then filled, and finally closed within the apparatus. An FFS heavy bag is understood here to mean a bag filled with a filling material having a weight of at least 5kg (filling weight). Usually even bags having a fill weight of at least 25 kg. The hose tracks used usually, but not exclusively, have side folds. The bag thus produced therefore has a first wall and a second wall which are connected to one another by a lateral edge or lateral fold and by a bottom. Thereby bounding the bag interior space. It is easy to understand that in the case of lateral folds, these are likewise connected to the two walls by lateral edges.

The invention with the publication number of CN109228526A discloses a bag making edge inserting machine, which comprises an edge inserting rack, wherein two groups of edge inserting wheels are symmetrically arranged on the edge inserting rack in the horizontal direction, the horizontal distance between the two groups of edge inserting wheels is adjustable, and each group of edge inserting wheels is provided with an installation rack, a polished rod, an adjusting screw rod, a nut seat, an adjusting hand wheel and the like for installing the edge inserting wheels.

The edge inserting wheel has unique edge inserting wheel and limiting design, can improve the edge inserting efficiency and the product quality, and has adjustable space and wide application range.

However, since the double-wrapped bag is generally wound before passing through the edge-inserting machine, and both walls of the bag in the wound state are in a bonded state, if the bag is not artificially spread, both the walls of the bag are generally folded up to one side at the same time when both the side edges of the bag are pressed by the edge-inserting wheel, and it is difficult to generate a necessary M-shaped edge-inserting.

Disclosure of Invention

Aiming at the defects in the prior art, one of the purposes of the invention is to provide an FFS heavy bag edge inserting machine which has the beneficial effects of continuously expanding the integrally connected FFS heavy bags and ensuring that the side edges of the bags form regular M-shaped inserting edges between two side walls.

One of the above objects of the present invention is achieved by the following technical solutions:

an FFS heavy bag edge inserting machine comprises a mounting frame, a guide roller arranged at one end of the mounting frame, a pair of pressing rollers arranged at the other end of the mounting frame and a motor for driving the pressing rollers to rotate, wherein an edge inserting mechanism is arranged between the guide roller and the pressing rollers and comprises two edge inserting wheel sets respectively connected to two sides of the mounting frame, each edge inserting wheel set comprises at least two edge inserting wheels, the thickness of each edge inserting wheel decreases from one end close to the guide roller to one end far away from the guide roller one by one, and the distance between two opposite edge inserting wheels in the two edge inserting wheel sets gradually decreases; and a support frame for supporting the bag is arranged between the edge inserting wheel set and the guide roller, and the bag wraps the support frame and passes through the periphery of the support frame.

By adopting the technical scheme, the bag is led out from the bag roll, passes through the guide roller, is sleeved on the support frame from the outside of the support frame, is supported by the support frame, is gradually extruded from the lateral edge of the bag by the edge inserting wheel, and is extruded towards the middle until the final M-shaped inserting edge is formed. In the process, the support frame positioned in the bag is arranged, so that two walls of the bag which are originally tightly attached together can be unfolded, the edge inserting wheel can conveniently extrude the bag from the side edges to the middle, and the final ideal edge inserting shape is formed.

The present invention in a preferred example may be further configured to: prop the type frame and include two fixed plates and locate two between the fixed plate prop the type roller, the parallel is equipped with a pair of first supporting roller on the mounting bracket, two first supporting roller is close to the interval of one side each other and is greater than two prop the interval of type roller axis and be less than two prop the type roller and keep away from the interval of one side each other, first supporting roller level sets up, two the level is arranged out between the first supporting roller, prop the type frame support two between the first supporting roller, two walls of sack press from both sides respectively between one of them props the type roller and first supporting roller.

Through adopting above-mentioned technical scheme, utilize first supporting roller and prop the butt between the type roller for prop fixing that can be stable under the condition of not being connected between type frame and the mounting bracket in definite position, realize spacing to propping the type frame, and guaranteed that the sack can be smooth parcel props type frame, and constantly from propping the type frame periphery and passing through, the structure is ingenious, reasonable in design, prop the bag effectual.

The present invention in a preferred example may be further configured to: one or more balance rollers are further arranged between the fixing plates, and the balance rollers are symmetrically arranged relative to a symmetrical plane between the support rollers.
