Description

Technical Field

[0001] The present invention relates to the technical field of packaging equipment, and in particular to a heavy-load merging and conveying device for soft packages. Background Art

[0002] In industrial production, it is often necessary to transport materials packed in ton bags. These materials are usually large in size and heavy in weight. Traditional conveying equipment may have some limitations when handling ton bag materials. For example, linear conveyors can only transport in a straight line. For some needs that require turning transportation, the ton bags are usually placed on pallets for transportation. Or the ton bags are transported to a separate conveyor, which is moved 90° to achieve the turning transportation of the ton bags. Both of these conveying methods have different disadvantages. The former requires pallets and has a high cost of use. The latter can only complete the conveying turning of ton bags, occupies a large area, and cannot complete the merging of multiple conveyor lines into one conveyor line.

[0003] The patent "A three-chain plate type transfer chain plate machine" (CN207985918U) proposes a transfer chain plate machine in which the long chain plate in the middle part first contacts the ton bag to provide tension when connecting ton bags. After conveying a certain distance, the long chain plate and the short chain plates on both sides provide tension at the same time to convey the ton bag to the middle of the transfer chain plate machine. After the chain plate machine rotates as a whole in situ, the ton bag packaging is output according to the same principle. Although this solution can solve the above-mentioned drawbacks, because the long chain plate only provides tension to one-third of its width when it just contacts the bottom of the ton bag, when the bottom of the ton bag is soft, there is still a phenomenon of bag jamming in the gap between the front conveyor and the transfer chain plate machine.

[0004] Therefore, in order to meet the problems of ton-bag steering and conveying during factory production and combining multiple conveyor lines into one conveyor line, and to ensure the success rate of ton-bag conveying, it is urgent to develop a heavy-load combined conveying device for soft bags.
