Automatic bag opening and sealing machine and automatic bag opening and sealing method

Abstract

The invention discloses an automatic bag opening and sealing machine. The machine comprises a rack, a bag opening device located on the rack and connected with a vacuum unit, a sealing heating device for heat-bonding a bag, a rail device for the moving of the bag opening device, and an additionally arranged bag pressing device, wherein the bag pressing device is used for tightly pressing two sides of the bag of which the opening is opened, and comprises a sliding claw device and a pressure regulator, the sliding claw device comprises a guide rail mechanism, a push-pull air cylinder mechanism, a sliding claw mechanism and an elevator mechanism, the guide rail mechanism moves under the action of the push-pull air cylinder mechanism, the sliding claw mechanism is driven to move, and further the edge of the bag opening is tightly pressed by the elevating of the elevator mechanism. The invention also discloses an automatic bag opening and sealing method.

Description

technical field [0001] The invention relates to the field of sealing machines, in particular to an automatic bag opening and sealing machine and an automatic bag opening and sealing method thereof. Background technique [0002] Plastic bags are very common for food and medicine packaging. The general packaging method is to print and manufacture plastic bags first. The three sides of the plastic bag are glued and sealed, leaving one side unsealed. Food and medicine are loaded from the opening, and then, Use a plastic sealer to seal the remaining one of the pockets to complete the plastic bag packaging of the item. [0003] At present, it is generally used to manually open the mouth of the plastic bag, and then put food and medicine into it, which is inefficient and labor-intensive, which is not conducive to high-efficiency large-scale flow production. [0004] The patent No. is "201120045078.7", and the patent titled "plastic bag opening device" discloses a plastic bag openi...

AI Technical Summary

Problems solved by technology

[0005] However, the suction of the vacuum suction cup is limited. On the one hand, the tightly closed plastic bag cannot be pulled open firmly; Fast loading, and during the whole process of loading, the vacuum suction cup must always work, which wastes resources to a certain extent

[0006] In the prior art, the equipment for bag opening and sealing is independent. In actual application, manpower must be supplemented to complete the process of bag opening, filling and sealing.
