A driving device for a medium-package machine

Abstract

The invention discloses a medium package machine driving device which comprises a driving motor and a camshaft. The camshaft is connected to the driving motor. The driving device further comprises package pushing cams, a first package pushing swing arm, a package pushing connecting rod, a second package pushing swing arm, a third package pushing swing arm, a fourth package pushing swing arm, a fifth package pushing swing arm, a roller, a pressing board, a belt absorbing cam, a first bag absorbing swing arm, a bag absorbing connecting rod, a second bag absorbing swing arm, an open claw cam, an open claw swing arm and an open claw connecting rod. Lifting and falling motion of a pushing rod of a medium package machine, forward and backward motion of an open claw component and lifting and falling motion of a bag absorbing rod are all driven through the cams and achieved through one driving motor, a whole driving mechanism is stable and reliable, and debugging is simple and easy.

Description

technical field [0001] The invention relates to a tundish machine, in particular to a driving device of the tundish machine. Background technique [0002] The medium packaging machine is widely used in the packaging field, and is often used for the packaging of daily necessities such as toilet paper, diapers and sanitary napkins, and is also used for the packaging of foods such as bread, pastries and pastries. [0003] For example, the publication number is CN102649485A, and the Chinese invention patent application with the publication date of August 29, 2012 discloses a plastic packaging machine, especially relates to a packaging machine for packaging sanitary products such as sanitary napkins, paper diapers, toilet paper, etc. It includes a feeding line, a packaging bag conveying line and a packaging bag sealing and cutting machine connected in sequence, and also includes a push rod mechanism for pushing products from the feeding line to the packaging bag sealing and cutti...

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
