Description

Technical Field

[0001] The utility model belongs to the field of packaging bag production equipment, in particular to an exhaust component of packaging bag production equipment. Background Art

[0002] In the production process of plastic bags, paper bags or other types of packaging bags, they are often processed from multiple layers of film. If there is gas between each layer of film, there will also be gas on the surface of the packaging bag when it is processed into a packaging bag, which will affect the judgment of whether the packaging bag is leaking. Therefore, exhaust components are needed to remove gas, bubbles or air in the bag to ensure the flatness and sealing of the inside of the bag. These exhaust components play a key role in the manufacturing process of packaging bags and can affect the quality and appearance of packaging bags.

[0003] The common exhaust methods in packaging bag production are as follows:

[0004] Vent holes: During the manufacturing process of packaging bags, vent holes can be set on one or more sides of the bag to allow the gas in the bag to be discharged. These vent holes are usually made by equipment such as perforators or laser cutting.

[0005] Vent: For liquid or gas packaging bags, vents may be set at the bottom or top of the bag to facilitate the removal of bubbles or gas in the bag and ensure the flatness of the inside of the bag.

[0006] Vacuum packaging machine: For some packaging bags that require high sealing and freshness preservation, such as food packaging bags, vacuum packaging machines may be used. This equipment can extend the shelf life of food by extracting the air in the packaging bag to form a vacuum state.

[0007] Compression exhaust device: During the sealing and forming process of the packaging bag, a compression exhaust device may be used to exhaust the gas in the bag by applying pressure or squeezing the bag to ensure the flatness and sealing of the seal.

[0008] Gas extraction system: For some products that require special atmosphere packaging, a gas extraction system may be used to extract the gas in the packaging bag and then fill it with specific gas to achieve the purpose of preserving, antiseptic or protecting the product.

[0009] CN217970250U provides a feeding and exhaust device for packaging bag production, comprising a fixed base, wherein the left and right ends of the fixed base are respectively fixedly installed with fixed vertical plates, a conveyor belt is rotatably installed on the fixed base, a plurality of limiting holes are evenly opened on the conveyor belt, and an extrusion device is respectively arranged on the inner end surfaces of the two fixed vertical plates, a plurality of vibration springs located in the conveyor belt are fixedly installed on the upper end of the fixed base, a vibration plate is fixedly installed between the plurality of vibration springs, an extension plate penetrating each fixed vertical plate is respectively fixedly installed on the left and right ends of the vibration plate, a storage box is respectively fixedly installed on the outer ends of the two fixed vertical plates, a vibration rod is respectively slidably installed up and down in the two storage boxes, a toggle rod is respectively fixedly installed on the upper ends of the two vibration rods, a rotating rod meshing with the extrusion device is respectively rotatably installed on the two fixed vertical plates, a cam is respectively fixedly installed on the outer ends of the two rotating rods, and a vibration disk is respectively fixedly installed on the lower ends of the two vibration rods.

[0010] The above method has a relatively complex structure, high cost and complicated processing process. Utility Model Content
