Description

Technical Field

[0001] The utility model relates to the technical field of splitting flexible container bags, in particular to a device for splitting flexible container bags. Background Art

[0002] Use flexible container bags to integrate and package the goods together, and use forklifts, cranes or other transportation tools to achieve containerized unit transportation. When producing flexible container bags, the fabric needs to be cut.

[0003] A Chinese patent discloses a device for dividing flexible bulk bags, with the publication number CN115056542A, comprising: a dividing seat with a through slot at its upper end; and a conveyor belt assembly, which is provided in two groups and movably installed in the through slot for transporting flexible bulk bags. The flexible bulk bag dividing device described in the present invention is capable of transporting the flexible bulk bag to the top of the dividing member through the provided dividing seat, conveyor belt assembly, support seat, first cylinder, first connecting rod, dividing piece, dividing tool, buffer tube, buffer rod and spring. The conveyor belt assembly is capable of transporting the flexible bulk bag to the top of the dividing member. The first cylinder and the connecting rod are used in conjunction to separate the flexible bulk bag through the dividing tool, thereby improving the dividing efficiency of the device. The cutting length is the same, and there will be no phenomenon of tearing or pulling of the cut, thereby improving the yield rate of the flexible bulk bag production. The provided mounting member and mounting frame enable the dividing member to be disassembled and maintained, making it convenient for people to use.

[0004] However, this system still has some drawbacks: The device controls the second cylinder to position the fabric with the pressing element, preventing it from shifting during cutting. However, the fabric is relatively soft, and wrinkles may form between the two pressing elements during fabric conveying. The device cannot tighten the fabric, which can result in uneven cutting positions. Therefore, we proposed a flexible container bag splitting device to address this problem. Utility Model Content
