Description
Technical Field
The invention relates to film bag production equipment, in particular to square bottom film bag production equipment.
Background
The conventional film bag is generally a strip-shaped bottom film bag, and the strip-shaped bottom film bag is generally manufactured by flattening a film cylinder into a sheet shape, then performing heat sealing on one end of the film cylinder to form a longitudinal heat sealing line 01, and unfolding the other end of the film cylinder to form a bag opening 02, so that the strip-shaped bottom film bag shown in fig. 1 is formed.
Such a strip-shaped bottom film bag cannot maintain a relatively stable form after being filled with a liquid such as water, for example, cannot maintain a form in which the bottom of the bag is stuck to the ground and the mouth 02 of the bag faces upward; in addition, when the strip-shaped bottom film bag filled with liquid is lifted upwards from the bag opening 02, the bag walls of the strip-shaped bottom film bag are generally closed towards the middle, a tip part is formed at the longitudinal heat seal line 01 of the bag bottom, and most of the pressure of the liquid acts on the longitudinal heat seal line 01 of the bag bottom, so that the longitudinal heat seal line 01 is easily separated locally to leak liquid; in addition, the bag wall of the strip-shaped bottom film bag is not limited by any shaping, and the whole strip-shaped bottom film bag is deformed randomly along with the flowing of the liquid, namely, cannot maintain a relatively stable form, and after the liquid is filled in, a large inflation space is difficult to form at the upper part of the liquid, so that the strip-shaped bottom film bag cannot be used for transporting fish fries, shrimp fries and the like.
In order to solve the above-mentioned problems of the strip-shaped bottom film bag, two transverse heat sealing lines 03 are added on the basis of the strip-shaped bottom film bag at present, namely, after the strip-shaped bottom film bag is opened, two ends of the longitudinal heat sealing line 01 at the bottom of the bag are respectively sealed with one transverse heat sealing line 03, and the transverse heat sealing lines 03 and the longitudinal heat sealing lines 01 are all positioned on the plane where the bottom of the bag is positioned and are vertical to each other, so that the square bottom film bag shown in fig. 2 is formed, and the upright relatively stable form can be maintained after liquid is filled.
However, at present, for the production of square-bottom film bags, a manual heat sealing mode is generally adopted, two workers are needed, one worker pulls two ends of a longitudinal heat sealing line 01 at the bottom of the strip-shaped bottom film bag, the two side bag walls at the lower part of the bottom of the other worker are pulled outwards, then folded edges are formed, the bag is placed on a heat sealing shearing device to seal along the folded edges, two transverse heat sealing lines 03 are formed and cut off, and finally the square-bottom film bag shown in fig. 2 is formed.
