Abstract

The present invention disclose a one time welding forming device for transfusion soft bag interface, including upper welding forming mould and lower welding forming mould formed by lock, inside the lower welding forming mould is provided with floatable lower interface welding floating forming mould, which is provided with heating pipe inside. The invention is a one time welding forming device for transfusion soft bag with simple and compact structure, low cost, simple and convenient operation, being capable of producing soft bag external shape and interface welding satisfied soft bag by one time welding.

Description

technical field [0001] The invention mainly relates to the field of pharmaceutical packaging products, in particular to a one-time welding forming device for an interface of a soft transfusion bag. Background technique [0002] The existing large infusion soft bag is made in two steps. The first step is to weld the special plastic film for the soft bag into the shape of the large infusion soft bag through high-temperature pressure welding in the soft bag welding forming mold. The plastic interface welding surface in the soft bag welding forming mold pre-welds the plastic film dedicated to the soft bag with plastic interfaces of various shapes. This pre-welding is virtual welding and needs to be performed twice at the subsequent plastic interface welding station. Welding can ensure that the plastic film and the plastic interface are welded firmly, preventing the occurrence of false welding problems and causing waste products. The main reason why the existing soft bag welding...
