Problems solved by technology

The current infusion soft bag production line adopts manual off-line sampling inspection, which is difficult to detect and the labor intensity of workers is also high; in the production process, when the heat sealing strength changes and cannot meet the standard, effective measures cannot be taken immediately to carry out inspections on the production line. control, resulting in a large number of substandard products

Embodiment 1

[0026] Such as figure 1 , figure 2 , image 3 As shown, the on-line detection device for the heat sealing strength of the infusion soft bag of the present invention is located at the filling station of the infusion soft bag production line. The filled filling needle 14 is provided with a liquid filling on-off valve 4 on the liquid path connected to the filling needle 14 . The needle filling part 1 can move up and down under the drive of the filling lifting part 6. When the needle filling part 1 descends and presses and seals with the interface of the infusion soft bag 8, the filling needle 14 is just communicated with the infusion soft bag 8. The on-line detection device for heat seal strength of soft infusion bags of the present invention includes an inflatable passage 131 provided on the filling needle part 1 for communicating with the soft infusion bag 8 to be tested, an inflatable part 17 connected to the inflatable passage 131, and a detection assembly. Like the filli...

Embodiment 2

[0033] Such as Figure 4 As shown, the structure of this embodiment is roughly the same as that of Embodiment 1, except that the vacuum degree detector 5 and the vacuum suction bag part 9 are removed, and the air path between the inflatable part 17 and the inflatable channel 131 and A flow meter 12 is arranged on the air path between the air extraction component 11 and the air extraction channel 132 .

[0034]The detection principle is as follows: first, the inflatable part 17 fills the infusion soft bag 8 with compressed gas of a set pressure and maintains the pressure for a certain period of time, monitors the intake flow through the flow meter 12, then closes the intake on-off valve 2, opens the The air outlet on-off valve 3, the air pumping part 11 starts to pump air, pump out the compressed gas in the infusion soft bag 8, and collect data through the flow meter 12, if the flow rate of the extracted gas matches the intake flow rate, it means that the gas in the infusion so...

Embodiment 3

[0036] Such as Figure 5 As shown, the difference between this embodiment and Embodiment 2 is that the detection component includes a pressure sensor 18 arranged on the air path between the intake on-off valve 2 and the inflation channel 131 .

[0037] The detection principle is as follows: fill the infusion soft bag 8 with compressed gas of a set pressure and keep the pressure for a certain period of time, then close the air intake on-off valve 2, if the detection data of the pressure sensor 18 is consistent with the pressure in the bag, it means If there is no leakage of gas in the soft infusion bag 8, it can be determined that the soft infusion bag 8 is not damaged, that is, the heat sealing strength is qualified; It has been damaged, that is, the heat sealing strength is not enough.

Abstract

The invention discloses a transfusion soft bag heat-seal strength on-line detecting device which comprises an air inflation part, bag pressing plate parts, an air inflation channel and a detecting component. The air inflation channel is arranged on a needle filling part at a transfusion soft bag production line filling working position and is used for being communicated with a transfusion soft bag to be detected. The detecting component is used for detecting whether the transfusion soft bag is broken by expanding through air pressure. The air inflation part is connected with the air inflation channel. An air on-off valve is arranged on an air path between the air inflation part and the air inflation channel. The bag pressing plate parts are arranged on the two sides of the transfusion soft bag to be detected and can tightly press the transfusion soft bag after air inflation expansion. The detecting component comprises travel switches or optoelectronic switches which are arranged on the bag pressing plate parts and are matched with the transfusion soft bag for action. The invention further discloses a transfusion soft bag production line which comprises the filling working position, and the transfusion soft bag heat-seal strength on-line detecting device is arranged on the filling working position. The transfusion soft bag heat-seal strength on-line detecting device is simple and compact in structure, low in cost, convenient to control, high in reliability and capable of achieving real-time on-line detecting, the labor intensity of workers is lowered, and bag manufacturing pass rate is improved.

Description

[0001] This application is a divisional application [0002] The filing date of the original application is: July 04, 2012 [0003] The application number of the original application is: 201210229491.8 [0004] The invention title of the original application is: an on-line detection device for heat sealing strength of soft transfusion bags and a production line for soft transfusion bags. technical field [0005] The invention mainly relates to the field of medical packaging equipment, in particular to an on-line detection device for heat sealing strength of soft infusion bags and a production line for soft infusion bags. Background technique [0006] The bag-making process of the infusion soft bag production line is to heat-weld non-PVC films and interfaces of different shapes and specifications through corresponding welding molds. The temperature, time and pressure of heat-sealing welding are currently commonly used welding control parameters. In order to ensure the quali...
