Automatic packaging machine and operating method thereof

Abstract

The invention relates to an automatic packaging machine and an operating method thereof. The machine comprises a bag feeding device, a bag sheathing device, and a sealing bag-delivery device. The bag feeding device comprises a bag crossing catch rod for catching on a bag-carrying opening of a packaging bag. The bag crossing catch rod is driven by a first driving mechanism to swing up and down. A first sucking disc is arranged above a first belt conveyor mechanism. The first sucking disc is driven by a second driving mechanism to move laterally and vertically and driven by a third driving mechanism to swing up to place the sucked packaging bag on the first belt conveyor mechanism. The bag feeding device is provided with two bag hanging mechanisms operating alternatively. The bag sheathing device comprises a bag opening mechanism, a bag distracting and conveying mechanism and a bag fixing and arranging mechanism which are arranged on a frame. The sealing bag-delivery device comprises a bag fixing and arranging mechanism, a heat-sealing mechanism and a cold pressing mechanism which are arranged above a second belt conveyor mechanism in order in an output direction. Finger cylinder groups for clamping a packaging bag are arranged on the upper portions of both sides of the second belt conveyor mechanism, and each finger cylinder group comprises a first finger cylinder, a second finger cylinder, and a third finger cylinder, and is fixed to a second slider. The automatic packaging machine is capable of achieving automatic packaging, and also can ensure the quality of sealing.

Description

technical field [0001] The invention relates to an automatic packaging machine and a working method. Background technique [0002] In the traditional packaging process, it is necessary to manually put the packaging bag on the blanking port, and then manually straighten the bag mouth after the blanking is completed, and then heat seal it with a sealing machine. This method has low production efficiency, and the labor intensity of workers is also relatively large, and the sealing positions are not the same due to manual differences. However, the bagging machine that was born in the later period usually uses the motor as the main power source for bag feeding. This kind of mechanism is relatively complicated, consumes a lot of energy, and has a high failure rate. The sealing part uses a special bag sorting mechanism to deal with the opening of the packaging bag during heat sealing, because the shape of the packaging bag mouth after filling is different, which often results in u...

Problems solved by technology

This method has low production efficiency, and the labor intensity of workers is also high, and the sealing positions are not the same due to manual differences.

The bagging machine that was born in the later period usually uses the motor as the main power source for bag feeding. This kind of mechanism is more complicated, consumes a lot of energy, and the failure rate is also high.

The sealing part uses a special bag sorting mechanism to deal with the opening of the packaging bag during heat sealing, because the shape of the packaging bag mouth after filling is different, which often results in unsatisfactory bag sorting effect and affects the heat sealing.
