Lifting device for welding sealing cover in big soft infusion bag production line

Abstract

The invention discloses a lifting device for welding sealing covers in a big soft infusion bag production line, comprising a driving mechanism, an oscillating arm, a lifting slide shaft and a welding head of the sealing cover; wherein, an output end of the driving mechanism is connected with the oscillating arm, a lifting slide shaft is sheathed on a lifting base, the top of the lifting slide shaft is provided with the welding head of the sealing cover, and the bottom of the lifting slide shaft is connected with the oscillating arm through a connecting rod. The lifting device for the sealing cover welding in the big soft infusion bag production line of the invention has simple and compact structure, low cost and reliable use, and is not easy to be damaged.

Description

Lifting device for sealing cover welding of large infusion soft bag production line Technical field The invention mainly relates to the field of medical packaging equipment, in particular to a lifting device for welding the sealing cover of a large infusion soft bag production line. Background technique The large infusion soft bag production line needs to weld the sealing cover to the soft bag interface after the bag is made and filled to form a completely sealed soft bag with a good liquid medicine. The sealing cap welding head of the existing large infusion soft bag production line needs to be lifted and lowered according to a certain motion law. There are two ways to realize the lifting motion in the prior art. One is to use two cylinders connected together to pass the program. Control to achieve, the other is to use a servo motor to drive a linear drive through program control. The former method uses two cylinders to achieve the lifting action. Because the cylinder and th...

Problems solved by technology

The former method uses two cylinders to realize the lifting action, because the cylinder and the solenoid valve driving the cylinder are relatively easy to damage and affect the sealing cover welding production of soft bag products, and the acceleration of the cylinder is not easy to control, the acceleration is relatively large, and the impact The force is relatively large, and it is easy to cause vibration and damage to other vital parts.

The latter uses a servo motor to drive a linear driver to realize the lifting action through program control. Although the acceleration can be set freely to avoid a large impact force, but because a linear driver is required, the cost of the linear driver is relatively high and the length of time is high. Some internal parts are also easily damaged during time running, which also affects the sealing cover welding production of soft bag products
