Description

Technical Field

[0001] The present invention relates to the technical field of inner bag processing, and particularly to an efficient preparation and processing device and a preparation method for forming a bulk bag inner bag. Background Art

[0002] A bulk bag, also known as a ton bag or a ton sack, is a flexible packaging container, which is mostly used in the upstream industries of the industrial chain, such as the packaging and transportation of bulk commodities such as mineral products, chemical products, grains, and cement. It is a low-cost and large-capacity packaging suitable for rapid loading and unloading, and has been widely used for nearly two decades.

[0003] Most bulk bags adopt the form of an inner bag and an outer bag. The inner bag is mostly made of materials such as PE and aluminum foil. The inner bag is nested into the outer bag to play a role in isolating and strengthening the protection of the bag body. The outer bag has loading and unloading ports and shows an obvious state of size reduction. However, since most of the existing inner bags are straight cylinder structures, during the unloading process, the inner bag in the unloading port is forced to be constricted in a smaller unloading port structure, resulting in congestion of the inner bag, poor unloading, affecting the unloading speed, and thus reducing the working efficiency of the unloading process. To solve this problem, a new manufacturing process has been adopted in the prior art: the cylindrical liner blank is manually cut into four pieces, and after manual alignment, it is heat-sealed by a heat-sealing machine to form a new square inner bag. Although this method can solve the problem of the closing of the square inner bag, it still cannot solve the problem of the loading and unloading closing of the straight cylinder inner bag, and at the same time, it will cause problems such as too low manual operation efficiency, high machine equipment and labor costs, and high labor intensity.

[0004] Moreover, through research, it is found that in other fields that require the use of formed inner bags, there are also problems of low forming efficiency and high processing costs due to limitations in equipment and process conditions. Summary of the Invention
