[0002] During the process of powder packaging, it is often necessary to stack the packaged powder bags to form a packaging stack for the convenience of subsequent packaging and transportation. However, when stacking the packaging stack, it may be not neatly stacked due to various reasons. At this time, a shaping machine is needed to shape the packaging stack to make it neat.

[0003] When the existing shaping machine is in use, the top plate used for compacting the top is often a whole piece of plate formed integrally. When the pressing plates on both sides compact the two sides of the packaging stack, they need to close towards the middle. At this time, the integrally formed top plate cannot flexibly adapt to the distance between the pressing plates, so there are limitations in use and the applicable range is low. Therefore, it is necessary to design a new shaping device to solve this problem. Content of the Utility Model

[0004] The purpose of the utility model is to provide a shaping device for powder packaging stacks to solve the problem that the top plate of the existing shaping machine cannot flexibly adapt to the distance between the two pressing plates on both sides mentioned in the above background technique.
