[0087] In order to facilitate the understanding of the present invention, specific embodiments of the present invention will be described in more detail below with reference to the accompanying drawings.

[0088] Unless otherwise specified or defined, the "first, second..." used in this article is only used to distinguish names and does not represent a specific quantity or order.

[0089] Unless stated otherwise or defined otherwise, the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0090] It should be noted that, in this document, “fixed to” or “connected to” may mean directly fixing or connecting to an element, or indirectly fixing or connecting to an element.

[0091] like Figure 1 As shown, the bagging machine provided in this embodiment includes a base 100, wherein the height direction of the base 100 is set as the first direction, the length direction of the base 100 is set as the second direction, and the width direction of the base 100 is set as the third direction.

[0092] A material conveyor belt 120 and a discharge conveyor belt 130 are provided on the top of the machine base 100 . The material conveyor belt 120 is used to transport materials to be packaged, and the discharge conveyor belt 130 is used to transport empty packaging bags and packaging bags with materials.

A pushing assembly 400 is set at the end of the material conveyor belt 120, and a sealing assembly 500 is set at a position between the end and the edge of the machine base 100. A bag supply assembly 200 is set at a position between the front end of the discharge conveyor belt 130 and the edge of the machine base 100. This can improve the structural compactness of the bagging machine, reduce the volume of the equipment, reduce the space occupancy rate, and increase the scope of application.

[0094] A bag opening assembly 300 for opening the bag mouth of the packaging bag is provided between the material conveyor belt 120 and the discharge conveyor belt 130 so that the material pushing assembly 400 can push the material into the packaging bag.

[0095] During use, the material conveyor belt 120 moves to the end of the material conveyor belt 120, and the bag supply component 200 transports the packaging bag to the discharge conveyor belt 130. The discharge conveyor belt 130 transports the empty packaging bag to the bag opening component 300. The bag opening end of the bag opening component 300 extends into the packaging bag and opens the packaging bag. At this time, the pushing component 400 pushes the material into the packaging bag. After the bag opening component 300 and the pushing component 400 are reset, the packaging bag containing the material reaches the sealing component 500 under the continued transportation of the discharge conveyor belt 130. The vacuuming end of the vacuuming component 580 enters the packaging bag to exhaust air, and resets after the exhaust is completed. The sealing component 500 seals the packaging bag.
