A driving mechanism of a medium-package machine

Abstract

The invention discloses a driving mechanism of a medium packing machine. The driving mechanism comprises a driving motor and a camshaft, and the camshaft is connected onto the driving motor. The driving mechanism further comprises a bag pushing cam, a first bag pushing swing arm, a bag pushing connecting rod, a second bag pushing swing arm, a third bag pushing swing arm, a fourth bag pushing swing arm, a fifth bag pushing swing arm, a roller and a pressing plate. Under the mechanical matching of the bag pushing cam, the bag pushing connecting rod and the bag pushing wing arms, a push rod of the medium packing machine is driven to rise and fall, and the bag pushing action is completed. The cam is used for driving, and the whole driving mechanism is stable, simple to regulate and easy to operate.

Description

Technical field [0001] The present invention relates to a tundish machine, in particular to a drive mechanism of the tundish machine. Background technique [0002] Tundish packaging machines are widely used in packaging collars and middleware. They are often used for the packaging of daily necessities such as toilet paper, diapers and sanitary napkins, as well as for the packaging of foods such as bread, pastries and pastries. [0003] For example, the publication number is CN102649485A, and the publication date of the Chinese invention patent application on August 29, 2012 discloses a plastic packaging machine, especially a tundish machine for packaging sanitary napkins, diapers, toilet paper and other sanitary products. It includes a feeding line, a packaging bag conveying line, and a packaging bag sealing and cutting machine that are sequentially connected, and a push rod mechanism for pushing the product from the feeding line to the packaging bag sealing and cutting machine.

AI Technical Summary

Problems solved by technology

[0007] 1. The cylinder drive is not stable enough, and the action is not completed in place, especially in the case of fast packaging speed, the cylinder drive often does not complete the action in place, causing the lift height of the push rod to be insufficient to contact the packaged items, resulting in damage to the packaged items and blockage; or the lifting height of the suction bag rod is not enough, causing the packaging bag to not be loaded into the predetermined position in time, and the packaging operation cannot be completed

[0008] 2. Each action requires an independent cylinder to complete. There are many cylinders used. Each cylinder needs to be connected to a separate air supply mechanism. The mechanism is complex, takes up a lot of space, and requires a large amount of electricity, resulting in waste of electricity.

[0009] 3. It is driven by a single cylinder. When the equipment is installed and debugged, it is necessary to ensure the precise coordination of each action, and the workload of the workers is huge.

[0014] 1. Use the cylinder to realize the lifting action of the push rod of the bag pushing mechanism, the lifting action of the suction bag rod of the suction bag mechanism, and the retreat action of the claw opening mechanism. When the packaging speed of the middle bag machine is fast, the cylinder drive is often The action will not be completed in place, causing the lift height of the push rod to be insufficient to contact the packaged items, resulting in damage and blockage of the packaged items; or the lift height of the suction bag rod is not enough, resulting in the packaging bag not being able to be loaded into the predetermined position in time, and the packaging operation cannot be completed ;Each action requires an independent cylinder to complete, and there are many cylinders used. Each cylinder needs to be connected to a separate air supply mechanism. The mechanism is complex, takes up a lot of space, and requires a large amount of electricity, resulting in waste of electricity; , when the equipment is installed and debugged, it is necessary to ensure the precise coordination of each action, and the workload of the workers is huge

Since each cylinder works independently, once one of the actions is not in place, it cannot accurately cooperate with the other two actions, and the packaging action cannot be completed

Workers are required to re-adjust, wasting a lot of working time

[0015] 2. The existing drive mechanism driven by the cam cannot complete the lifting action of the push rod of the bag pushing mechanism, the lifting action of the suction bag rod of the suction bag mechanism and the retreat action of the claw opening mechanism, and cannot be used on the tundish machine to realize The function of the charter machine
