Problems solved by technology

[0004] In this way, in the first welding station, the two welding circuits need to be converted to each other, and the two welding steps are carried out in one station, so the time taken by the first station is the sum of the time of the two steps : t1=ta+tb+t auxiliary. It prolongs the standby time of other stations, increases the time of working steps and poor coordination at the same time, resulting in a decrease in operating efficiency
It has become a technical bottleneck restricting the automatic production of blood bags (PVC infusion bags) to improve production efficiency

Abstract

The invention provides a three-position bag welding mechanism. The three-position bag welding mechanism comprises a bag welding pipe position die, a bag welding head position die and a bag welding edge position die, wherein the bag welding head position die is connected between the bag welding pipe position die and the bag welding edge position die in parallel, and is respectively in ordered fit with the bag welding pipe position die and the bag welding edge position die. The three-position bag welding mechanism avoids conversion between welding modes, enables the welding performance to be more stable and shortens the auxiliary time.

Description

technical field [0001] The invention relates to the technical field of plastic molding equipment, in particular to a three-station welding bag mechanism. Background technique [0002] At present, most of the blood bags (PVC infusion bags) at home and abroad are made of PVC materials. After high-frequency equipment and molds, the accessory tubes and diaphragms of the bag are divided into three parts according to the sequence: tube and diaphragm, head diaphragm, and rest diaphragm. The first step is to weld the blood bag (PVC infusion bag) sequentially on the two stations. [0003] When welding at the first station, it needs to be welded twice: first, the upper and lower molds are connected to the high frequency, and the central positioning element of the nozzle is grounded to form a tube and a diaphragm for welding. After this step of welding, it is converted into a welding circuit where the upper mold is connected to high frequency and the lower mold is grounded to weld the...
