Description

Technical Field

[0001] The utility model relates to the technical field of infusion bag sealing, and more specifically, to a sealing detection device for the production of infusion bags. Background Art

[0002] An infusion bag is a container widely used for the delivery of liquid medicine in medical treatment. After the infusion bag is produced and formed, in order to prevent defective products from entering the market, it is usually necessary to detect the sealing performance of the infusion bag.

[0003] The patent with the publication number of CN113865804A discloses a batch detection device and detection method for the production of polypropylene infusion bags, including an operation table, a detection mechanism, an air inlet mechanism and a docking mechanism. The detection mechanism is installed on the operation table, the air inlet mechanism is installed on the detection mechanism, and the docking mechanism is installed on the air inlet mechanism. This patent detects the sealing performance of polypropylene infusion bags by putting the polypropylene infusion bags into water, then inflating the inside of the polypropylene infusion bags, and then observing whether there are bubbles generated manually. There are the following problems: 1. It is necessary to observe each infusion bag manually in real time, which is easy to cause visual fatigue. If there are small leakage holes and weak bubbles, it is easy to miss detection or misjudgment, and the detection effect is poor, making it difficult to ensure the accuracy of the detection results. 2. Because the material of the infusion bag itself is soft and easy to bend, when the polypropylene infusion bag is filled with air, under the buoyancy of water, the bag mouth of the polypropylene infusion bag filled with air will bend, causing the polypropylene infusion bag filled with air to float on the water surface. If the leakage part of the polypropylene infusion bag is higher than the water surface, it will be difficult to detect whether the sealing performance of the polypropylene infusion bag is qualified, thus making it difficult to ensure the accuracy of the detection results.

[0043] The utility model provides a sealing detection device for the production of infusion bags. The position of the infusion bag is fixed and the opening is unfolded mainly through the action of the first adsorption mechanism and the second adsorption mechanism, and the infusion bag is inflated by the air supply mechanism. Then, the opening of the infusion bag is sealed by the sealing mechanism. Finally, the pressure stability of the inflated infusion bag is detected by the pressure detection mechanism, and the qualification is judged through the feedback of the pressure detection mechanism, so as to improve the accuracy of detection.

[0044] The following is a detailed description of a sealing detection device for the production of infusion bags according to the present application through the following embodiments.

[0045] In this embodiment, as Figures 1 to 3 shown, the sealing detection device for the production of infusion bags includes: a support frame 1 for placing the infusion bag to be detected;

[0046] A first moving mechanism 2 is arranged on the support frame 1 and is used to drive the first adsorption mechanism 3 to move;

[0047] A first adsorption mechanism 3 is arranged on the first moving mechanism 2 and is used to adsorb the first side of the infusion bag to be detected;

[0048] A second adsorption mechanism 4 is arranged on the support frame 1 and is used to adsorb the second side of the infusion bag to be detected, and the first side and the second side are correspondingly arranged;

[0049] An air supply mechanism 5 is arranged on the support frame 1 and is used to supply air to the infusion bag to be detected;

[0050] A sealing mechanism 6 is arranged on the support frame 1 and is used to seal the opening of the infusion bag to be detected;

[0051] A pressure detection mechanism 7 is arranged on the support frame 1 and is used to detect the pressure of the infusion bag to be detected.

[0052] In this technical solution, the support frame 1 is horizontally arranged. The first moving mechanism 2 is arranged on the upper side of the support frame 1 through the support rib plate 101. The first moving mechanism 2 is provided with a horizontally front-back motor screw slider moving mechanism and a vertically arranged air cylinder. The screw slider moving mechanism of the first moving mechanism 2 is used to drive the air cylinder of the first moving mechanism 2 to slide back and forth. The first adsorption mechanism 3 is arranged on the air cylinder of the first moving mechanism 2, and the second adsorption mechanism 4 is arranged on the support frame 1. Both the first adsorption mechanism 3 and the second adsorption mechanism 4 are provided with a plurality of suction cups. The plurality of suction cups of the first adsorption mechanism 3 are fixed on the air cylinder of the first moving mechanism 2 and are arranged downward. The first adsorption mechanism 3 is used to adsorb the upper side of the infusion bag to be detected. The plurality of suction cups of the second adsorption mechanism 4 are fixed on the support frame 1 and are arranged upward. The second adsorption mechanism 4 is used to adsorb the lower side of the infusion bag to be detected. The plurality of suction cups of the first adsorption mechanism 3 and the second adsorption mechanism 4 are respectively connected to a negative pressure machine through a control valve (not shown in the figure). Negative pressure is provided by the negative pressure machine, and the opening and closing of each suction cup are controlled through the control valve.

[0053] The air supply mechanism 5 is provided with an intake valve, a gas cylinder (not shown in the figure), and an air supply pipe 501. The on-off between the gas cylinder and the air supply pipe 501 is controlled through the intake valve. The gas cylinder conveys an inert gas or a sterile gas into the infusion bag to be detected through the air supply valve, so that the infusion bag to be detected expands. The sealing mechanism 6 is arranged corresponding to the opening of the infusion bag on the second adsorption mechanism 4. After the air supply mechanism 5 fills a certain amount of gas into the infusion bag, the opening of the infusion bag is sealed through the sealing mechanism 6. The pressure detection mechanism 7 is a pressure sensor arranged on the support frame 1.

[0054] During use, when the first adsorption mechanism 3 moves the infusion bag to the second adsorption mechanism 4 and adsorbs on the upper and lower sides of the infusion bag through the first adsorption mechanism 3 and the second adsorption mechanism 4, then the air cylinder of the first moving mechanism 2 is used to drive the first adsorption mechanism 3 to move upward a small distance, so that the opening of the infusion bag opens under the negative pressure of the two-side adsorption mechanisms. Then, air supply and sealing at the opening are carried out through the air supply mechanism 5 and the sealing mechanism 6. The air cylinder of the first moving mechanism 2 is used to keep the first adsorption mechanism 3 in contact with the air-supplied infusion bag, and the expanded infusion bag generates pressure on the pressure detection mechanism 7. When the pressure detected by the pressure detection mechanism 7 gradually decreases, it indicates that there is a quality problem of air leakage in the detected infusion bag. When the pressure detected by the pressure detection mechanism 7 remains unchanged, it indicates that the quality of the detected infusion bag is qualified.

[0055] In some technical solutions, at least one suction cup in the plurality of suction cups of the first adsorption mechanism 3 and the second adsorption mechanism 4 is arranged corresponding to the opening position of the infusion bag.

[0056] In some other technical solutions, the sealing requirement of the sealing mechanism 6 for the opening of the infusion bag can also be reduced, so that the gas in the infusion bag can leak through the opening when the pressure detection mechanism 7 detects. In this case, the pressure value detected by the pressure detection mechanism 7 gradually decreases. The leakage speed can be fed back by comparing the change rate of the pressure value, and finally it can be fed back whether there is a leak in the infusion bag.

[0057] In this embodiment, the sealing mechanism 6 includes:

[0058] A second moving mechanism 601, arranged on the support frame 1, for driving the unfolding mechanism 602 to move;

[0059] An unfolding mechanism 602, arranged on the second moving mechanism 601, for expanding the opening of the infusion bag to be detected;

[0060] A pressing mechanism 603, arranged on the support frame 1, for sealing the opening of the infusion bag to be detected unfolded by the unfolding mechanism 602.

[0061] In this technical solution, the second moving mechanism 601 is a horizontally arranged cylinder, fixed on the upper side of the support frame 1.

The pressing mechanism 603 is arranged on the support rib 101 of the support frame, and the pressing mechanism 603 is vertically arranged and corresponds to the opening of the infusion bag on the second adsorption mechanism 4.

[0062] After the first adsorption mechanism 3 and the second adsorption mechanism 4 unfold the opening of the infusion bag with the help of the cylinder of the first moving mechanism 2, the unfolding mechanism 602 and the liquid supply pipe of the liquid supply mechanism 5 are extended into the opening of the infusion bag through the second moving mechanism 601, and then the opening of the infusion bag is pressed by means of the pressing mechanism 603 to ensure the accuracy and effect of the sealing.

[0063] In this embodiment, the unfolding mechanism 602 includes:

[0064] A sliding member 604, connected to the second moving mechanism 601, and the second moving mechanism 601 is used to drive the sliding member 604 to move;

The third moving mechanism 605 is used to drive the first support member 606 and the second support member 607 to move towards or away from each other. The first support member 606 and the second support member 607 are used to open the opening of the infusion bag to be detected.

[0067] In this technical solution, the sliding member 604 is fixed on the telescopic shaft of the second moving mechanism 601, and the second moving mechanism 601 can drive the sliding member 604 to move left and right. The sliding member 604 is provided with a chute for restricting the rotation of the first support member 606 and the second support member 607. The first support member 606 and the second support member 607 are slidably disposed on both sides of the chute of the sliding member 604. The front and rear sides of the right ends of the first support member 606 and the second support member 607 are provided with arc chamfers. The third moving mechanism 605 is a screw slider moving mechanism, and the screw of the third moving mechanism 605 is provided with two sections of symmetric threads before and after. The first support member 606 and the second support member 607 are respectively symmetrically arranged on the two sections of threads of the third moving mechanism 605. The third moving mechanism 605 can synchronously drive the first support member 606 to move forward and the second support member 607 to move backward, or the third moving mechanism 605 can synchronously drive the first support member 606 to move backward and the second support member 607 to move forward.

[0068] In this embodiment, the pressing mechanism 603 includes:

[0069] A fourth moving mechanism 608, arranged on the support frame 1;

[0070] A pressing block 609, arranged on the fourth moving mechanism 608, and the fourth moving mechanism 608 is used to drive the pressing block 609 to approach or move away from the first support member 606 and the second support member 607.

[0071] In this technical solution, the fourth moving mechanism 608 is a vertically arranged telescopic cylinder, fixedly arranged on the support rib 101 of the support frame 1, and is located below the screw slider moving mechanism of the first moving mechanism 2. The pressing block 609 is arranged at the lower end of the fourth moving mechanism 608, and the pressing block 609 is arranged corresponding to the opening of the infusion bag when the infusion bag is located on the second adsorption mechanism 4. During use, the pressing block 609 is pressed between the first support member 606 and the second support member 607 through the fourth moving mechanism 608, and the opening of the infusion bag is tensioned around the first support member 606 and the second support member 607, and is also tensioned between the pressing block 609 and the first support member 606 and the second support member 607 respectively.

[0072] In some technical solutions, the materials of the pressing block 609, the right end of the first support member 606 and the right end of the second support member 607 are set as rubber materials.
