Filling head lifting device for big soft infusion bag production line

Abstract

The invention discloses a filling head lifting device for a big soft infusion bag production line, comprising a driving mechanism, an oscillating arm, a lifting sliding shaft and a filling head; wherein, the output end of the driving mechanism is connected with the oscillating arm, the lifting sliding shaft is sleeved on a lifting base, the upper end of the lifting sliding shaft is provided with the filling head, and the lower end of the lifting sliding shaft is connected with the oscillating arm through a connecting rod. The filling head lifting device for big soft infusion bag production line of the invention has simple and compact structure, low cost and reliable use and is not easy to damage.

Description

technical field [0001] The invention mainly relates to the field of medical packaging equipment, in particular to a filling head lifting device for a large infusion soft bag production line. Background technique [0002] The large infusion soft bag production line needs to fill the liquid medicine into the soft bag after bag making, and the filling nozzle is required to seal the interface of the soft bag during filling to prevent the liquid medicine from coming out of the interface during filling , When the filling nozzle seals the interface of the soft bag and the filling pipeline is cleaned and disinfected in place, the filling nozzle needs to have a lifting action. In the past, there are two ways to realize the lifting action of the filling nozzle in the large infusion soft bag production line. One way is that a cylinder with a longer stroke drives a filling head mounting plate to lift, and the filling head mounting plate is equipped with one and one Although the structu...

Problems solved by technology

In the past, there are two ways to realize the lifting action of the filling nozzle in the large infusion soft bag production line. One way is that a cylinder with a longer stroke drives a filling head mounting plate to lift, and the filling head mounting plate is equipped with one and one Although the structure of the above filling head is relatively simple and the cost is relatively low, since multiple filling heads are installed on one board, the sealing between the filling head and the interface is likely to occur due to the error of processing accuracy and packaging materials. Inconsistency leads to liquid leakage during filling. At the same time, because the stroke of one cylinder is relatively long, the movement range of the filling head is relatively large, which is also easy to cause damage to the filling hose; another way is to combine two cylinders together. , every two cylinders drive a filling head to lift. Compared with the first method, this method has lower precision requirements for parts and packaging materials (interfaces), and the sealing effect is better, but this method has a disadvantage. It is high cost, especially when the number of filling heads is relatively large, its cost disadvantage is even more prominent, so it is not an ideal filling head lifting device

The two methods also have a common disadvantage that because the cylinder is used to control the lifting of the filling head, the acceleration of the cylinder is not easy to control, the acceleration is relatively large, the impact force is relatively large, and it is easy to cause vibration. It is easy to cause the liquid medicine to drip out from the filling head during the action and affect the product quality
