Soft bag separate welding system, production line and method

Abstract

The invention discloses a soft bag separating type welding system. The separating type welding system comprises a top edge and connector welding mechanism, a side edge welding mechanism and a bottom edge welding mechanism. The top edge connector welding mechanism is used for welding top edge and connector areas of soft bags inserted in connectors. The side edge welding mechanism is arranged at the rear end of the top edge and connector welding mechanism and used for welding the side edges of the soft bags. The bottom edge welding mechanism is arranged at the rear end of the side edge welding mechanism and used for welding the bottom edges of the soft bags after filling of the soft bags is completed. The invention further provides a soft bag separating type welding method and a soft bag production line based on the separating type welding system. By means of the manner of separably welding the soft bags, the problems that the requirements of existing equipment for the flatness and machining precision of molds are restrict, time and labor are consumed when the molds are replaced, and large air cylinder pressure is needed are solved.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a soft bag separate welding system and method and a soft bag production line based on the separate welding system. Background technique [0002] With the increasingly fierce market competition, the popularity of conventional infusion bags makes the market competitiveness of conventional infusion soft bag products lower and lower. [0003] When traditional equipment prepares soft infusion bags, the welding process is as follows: the film roll (the film roll is a double-layer film that is tightly bonded together) is sent to the bag making station by the film pulling station, and the film splitter first separates the interface part of the end (the purpose is to facilitate the subsequent delivery of the interface, only a very narrow part of the interface is separated, most of which will not be separated), and then the preheated interface is sent between the two layers of fi...
