The invention relates to a detection method of an infusion soft bag prepared based on high-frequency heat sealing, and relates to heat sealing strength detection of the infusion soft bag. The detection method of the infusion soft bag prepared based on high-frequency heat sealing comprises the steps that a prepared polyethylene soft film is conveyed to a high-frequency heat sealing device through a conveying device controlled by a control module, hot pressing is conducted for t1 time at the preset pressure P1 and the preset temperature T1, and the infusion soft bag is obtained; the prepared infusion soft bag is conveyed to a cooling chamber for cooling; the cooled infusion soft bag is conveyed to a detection device, the infusion bag is filled with a preset amount of gas, and the detection device is moved to a preset position to extrude the infusion soft bag for detection; and during detection, a numerical value of a pressure sensor arranged on the detection device and an image scanned by an image scanner arranged on the detection device are acquired to judge whether the heat sealing strength of the infusion soft bag is qualified or not. The detection accuracy of the infusion soft bag is improved, so that the quality of the infusion soft bag is further improved.
Description
technical field [0001] The invention relates to the technical field of heat sealing strength detection of infusion soft bags, in particular to a detection method for infusion soft bags prepared based on high-frequency heat sealing. Background technique [0002] For infusion soft bags used for medical nutrient solution injection, its heat sealing performance is an important way to evaluate the quality of infusion soft bags. Infusion infusion soft bags with good heat sealing strength can ensure the quality of medical nutrient solution and avoid the risk of The problems of rupture of the infusion soft bag, oxygen permeability, nitrogen permeability and moisture permeability caused the effect of the nutrient solution to fail to meet expectations. [0003] The production process of the infusion soft bag is made by heat-sealing and welding the special polyethylene film through a heat-sealing machine. The heat-sealing temperature, time and pressure of the heat-sealing welding are t...
