Description

Technical Field

[0001] The utility model relates to the technical field of sealing machines, in particular to a municipal environmental protection sealing machine. Background Art

[0002] A sealing machine is a machine that seals containers containing products. After the product is loaded into the packaging container, in order to keep the product sealed and preserved, maintain product quality, and avoid product loss, the container needs to be sealed. This operation is completed by a sealing machine.

[0003] For example, the Chinese patent with publication number CN209796006U proposes a sealing machine. This patent fixes a pallet for supporting the packaging bags on the side of the sealing machine close to the processing of the staff. After the packaging bags are placed on the pallet, the pallet supports the packaging bags, saving the workers' effort in lifting the packaging bags. At the same time, the ball bearings connected to the pallet are convenient for changing the position of the placed packaging bags on the pallet, further saving the workers' effort, reducing the workers' fatigue, and increasing the workers' work efficiency. However, in this solution, since the device places the packaging bags on the pallet and moves them when sealing them, and the packaging bags are relatively soft, the workers may need to hold the packaging bags for sealing. At this time, the workers' hands may be close to the upper and lower hot pressing plates, which may cause burns to the workers, and the sealing effect of the packaging bags may be reduced.

[0029] Through the provided extrusion plate 6, when the electric heating plate 5 melts and seals the bag opening of the packaging bag, the staff starts the electric push rod 8 by using the PLC controller. The movement of the telescopic rod of the electric push rod 8 will drive the moving block 23 and the extrusion plate 6 to move, and then the extrusion plate 6 can be moved downward to make the extrusion plate 6 close to the packaging bag and squeeze it, and then cooperate with the electric heating plate 5 to melt the packaging bag, so as to facilitate the electric heating plate 5 to seal the packaging bag.

[0030] By setting the limiting post 24, when the staff seals the packaging bag, the staff extends the opening of the packaging bag out of the top surface of the placement plate 15, and then rotates the limiting post 24, so that the limiting post 24 moves downward to make the limiting post 24 close to the top surface of the packaging bag, thereby limiting the opening position of the packaging bag, preventing the bag opening from naturally opening or turning inside out when sealing, which affects the subsequent sealing of the packaging bag.
