Description

Technical Field

[0001] The utility model relates to the technical field of packaging material sorting machinery, and more specifically to a feeding turntable suitable for a strip bag filling machine. Background Art

[0002] The pillow packaging production line requires operation, but in the whole process, there are often unqualified strips that are weighed. These unqualified strips will be rejected at one time. Assuming that there are 10 strips of material in one flush, since one of them is an unqualified strip, the remaining 9 qualified strips will be rejected. The rejected strips need to be manually boxed, which not only seriously affects the continuity of the packaging operation, but also generates a lot of manpower and time costs.

[0003] At present, there are bag filling machines on the market that can reduce the rejection of qualified strip packs, increase packaging efficiency, and reduce manpower and time costs. For example, the utility model patent with announcement number CN220448271U and announcement date February 6, 2024, named "A high-efficiency bag filling machine suitable for pillow packaging machine", in which the strip packs are sorted and transported by a circular turntable. After the strip packs are transported from the feeding station to the circular turntable, the circular turntable rotates and rotates the strip packs to the discharging station accordingly, and the circular turntable is output from the discharging station. During the rotation of the circular turntable, the bar bags will be thrown out due to the centrifugal force. The solution of the utility model to solve this problem is to set a liftable transition bin between the circular turntable feeding bin and the conveyor line and between the feeding bin and the conveyor belt, and set an arc-shaped baffle between the transition bins; during feeding and discharging, the transition bin descends to a position flush with the feeding bin on the circular turntable to facilitate feeding; when the circular turntable rotates, the transition bin rises, and when the circular turntable starts to rotate and stops rotating, the bar bags in the feeding bin on the circular turntable are protected from being thrown out; the arc-shaped baffle located between the transition bins can also prevent the bar bags from being thrown out due to the centrifugal force during the rotation of the circular turntable, and cooperates with the transition bin to protect the bar bags throughout the rotation of the circular turntable.

[0004] The technical solution for solving the problem of strip packages being thrown out due to centrifugal force during circular rotation in the above-mentioned prior art is relatively complicated, that is, a transition bin and an arc-shaped baffle are set, and the transition bin needs to be lifted and lowered, resulting in high equipment costs.
