An automatic bagging device for straws

Abstract

This invention provides an automatic straw bagging device, including a base frame, a flipping component, a film guiding unit, a heat-cutting component, and a film roll. The flipping component is located at the upper end of the base frame and is used to flip the straws. The heat-cutting component is located at the output end of the flipping component and is used to cut the packaging film. The film guiding unit is located on one side of the base frame, at one end of the flipping component, and contains the film roll. This automatic straw bagging device, with its flipping component and heat-cutting component fixedly connected to the output end of the flipping component, transports a certain number of straws from upstream equipment to the flipping component, and then through the flipping component to the packaging film in the heat-cutting component for packaging. This reduces the risk of stacked straws being easily shaken apart during transport due to conveyor belt vibration, which could lead to the straws and plastic film being sealed together during the packaging process, requiring manual picking and resealing, resulting in wasted manpower and resources.

When the photoelectric sensor 24 detects a suction tube inside the storage box 22, it sends a signal back to the controller. The controller then controls the flipping cylinder 23 to retract, causing the storage box 22 to flip. At this time, the drive motor 425, controlled by the controller, rotates, driving the active roller 423 to rotate, which in turn drives the driven roller 424 to rotate and seal the packaging film. When the photoelectric sensor 24 detects that the suction tube is located on the side of the heating plate 432 and the pressure plate 434 away from the storage box 22, the controller controls the telescopic cylinder 433 to extend, which drives the heating plate 432 with the groove 4322 to move closer to the pressure plate 434.

Both ends of the packaging film are fixed by the active roller shaft 423 and the driven roller shaft 424. When the straw in the storage box 22 triggers the photoelectric sensor 24, the photoelectric sensor 24 sends a signal to the controller. The controller connects to and starts the flipping cylinder 23 to flip the outer shell 21 and send the straw to the output end of the storage box 22. Then, the controller signals the drive motor 425 of the hot cutting assembly 4 to rotate and drive the active roller shaft 423 and the driven roller shaft 424 to seal the packaging film. Then, the controller controls the telescopic cylinder 433 to push the heating plate 432 down along the slide groove 4311, so that the groove 4322 of the heating plate 432 cooperates with the blade 435 on the pressure plate 434 to perform hot melt welding and cutting of the packaging film, completing the automatic bagging of a single set of straws.
