[0002] At present, the powder-liquid double-chamber bag product is a ready-to-mix infusion product. The product includes a liquid chamber containing an injection solvent and a powder chamber containing drug powder. The two chambers are separated by a weakly welded partition strip. When in use, the powder and liquid stored inside are generally taken out through the bag head at one end. During manufacturing, after the double-chamber bag is manufactured, in order to prevent the bag body of the double-chamber bag from having sealing problems, the bag body of the double-chamber bag will be tested by a testing device, and a bag head detection device will also be used to detect the bag head of the double-chamber bag to avoid the bag head from leaking.

[0029] In order to further understand the content, features and effects of the utility model, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0030] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention unless otherwise specifically stated.

[0031] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses.

[0032] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0033] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0034] The structure of the utility model is described in detail below in conjunction with the accompanying drawings.

[0035] like Figures 1 to 5As shown, the bag head detection device provided by the embodiment of the utility model includes:

[0036] The first station includes two groups of positive wheels 4 and a first negative plate 5. The two groups of positive wheels 4 are arranged in correspondence with each other up and down, and the first negative plate 5 is arranged in correspondence with the two groups of positive wheels 4; the second station includes two groups of four-tooth wheels 1 and a second negative plate 2. The four-tooth wheel 1 is a positive electrode. The two groups of four-tooth wheels 1 are arranged in correspondence with each other up and down, and the space between the two teeth of the four-tooth wheel 1 is an arc shape for fitting the bag head. The second negative plate 2 is arranged in correspondence with the two groups of four-tooth wheels 1;

[0037] For details, please refer to Figure 1 , Figure 3 , Figure 4 and Figure 5 ,like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, in specific use, the double-chamber bag is conveyed to the first station, the bag body is located between the two sets of positive electrode wheels 4, and the lower half of the bag head is located on the second negative electrode plate 5, and then the high voltage between the first negative electrode plate 5 and the positive electrode wheel 4 is used to detect the bag head and the bag body;

[0038] After passing the inspection at the first station, the double-chamber bag continues to be transported to the second station. At this time, the bag head will be placed in the arc edge on one side of the four-tooth wheel 1, and the bag body will be positioned on the second negative electrode plate 2. Subsequently, the two groups of four-tooth wheels 1 will rotate a quarter of a turn at the same time, so that the arc shapes of the upper and lower groups of four-tooth wheels 1 correspond to each other, forming a circular groove to surround the upper and lower halves of the bag head. Subsequently, the high voltage between the four-tooth wheel 1 and the second negative electrode plate 2 is used to perform an overall inspection of the bag head, thereby effectively improving the inspection speed and inspection effect.

[0039] It should be noted that whether the product is qualified or not is determined by collecting a large amount of data from qualified samples after they pass through the electrodes. For example, if the qualified voltage is 12V, the voltage generated by the double-chamber bag when it passes through the positive wheel 4 and the first negative plate 5 does not exceed 12V, which is a qualified sample. After passing through the electrode, the voltage will be greater than the threshold value of 12V, which is an unqualified sample.

[0040] Furthermore, it also includes a support plate 18, the first station and the second station are both arranged on one side of the support plate 18, and the first station and the second station are arranged at the same level, and two groups of drive components 6 are arranged on the other side of the support plate 18, and the two groups of drive components 6 are respectively arranged corresponding to the first station and the second station;

[0041] Please refer to Figures 1 to 5 ,like Figures 1 to 5 As shown, the structures in the first station and the second station are operated by the driving assembly 6 .

[0042] Specifically, the driving assembly 6 includes a driving motor 601, a first gear 602 is provided at the output end of the driving motor 601, a second gear 603 is meshedly connected to one side of the first gear 602, and a third gear 604 is meshedly connected to the lower end of the second gear 603; two groups of first mounting seats 9 are provided at one end of one side of the support plate 18, and connecting columns 19 are rotatably installed in the two groups of first mounting seats 9, and one end of the two groups of connecting columns 19 is fixedly installed on the second gear 603 and the third gear 604 respectively, and a connecting rod 10 is provided on the outer surface of the other end of the connecting column 19, and the positive wheel 4 is rotatably installed on one end of the connecting rod 10; a spring 14 is provided at the other end of the connecting rod 10, and a clamping column 15 is provided on one side of the support plate 18, and the spring 14 is clamped with the clamping column 15;

[0043] Start the driving motor 601 to drive the first gear 602 to rotate, the first gear 602 drives the second gear 603, and the second gear 603 drives the third gear 604. When the second gear 603 and the third gear 604 rotate, the connecting column 19 at one end of the two rotates with them to drive the connecting rod 10 to rotate, so as to adjust the position of the positive wheel 4, so that the two groups of positive wheels 4 are close to each other to fit with the bag body of the double-chamber bag, thereby improving the detection effect and limiting the double-chamber bag at the same time.

[0044] It should be noted that, since the spring 14 itself is elastic, a pre-tightening effect is formed when the connecting rod 10 rotates.

[0045] Furthermore, a first rotating wheel 11 is provided at one end of the connecting column 19, a second rotating wheel 13 is fixedly installed at one end of the positive electrode wheel 4, and a belt 12 is provided between the first rotating wheel 11 and the second rotating wheel 13;

[0046] For details, please refer to Figure 4 When the connecting column 19 rotates, it drives the first rotating wheel 11, and through the cooperation of the belt 12, the second rotating wheel 13 rotates at the same time, thereby achieving the effect of rotating the two sets of positive wheels 4 to cooperate with the conveying device to convey the double-chamber bag.

[0047] Furthermore, two sets of second mounting seats 16 are provided at the other end of one side of the support plate 18, and rotating shafts 20 are rotatably mounted in the two sets of second mounting seats 16. One end of the two sets of rotating shafts 20 is respectively fixedly mounted on the second gear 603 and the third gear 604, and two sets of four-tooth wheels 1 are respectively fixedly mounted on the other ends of the two sets of rotating shafts 20;

[0048] Specifically, the driving motor 601 is started to drive the first gear 602 to rotate, the first gear 602 drives the second gear 603, and the second gear 603 drives the third gear 604. When the second gear 603 and the third gear 604 rotate, the rotating shaft 20 at one end of the two rotates with them to rotate the four-tooth wheel 1 to surround the bag head, thereby improving the detection effect of the bag head.

[0049] Further, two groups of first support rods 21 are provided at one end of one side of the support plate 18, and the two groups of first support rods 21 are respectively fixedly installed at both ends of the first negative electrode plate 5; two groups of second support rods 3 are provided at the other end of one side of the support plate 18, and the two groups of second support rods 3 are respectively fixedly installed at both ends of the second negative electrode plate 2;

[0050] For details, please refer to Figure 1 , Figure 4 and Figure 5 ,like Figure 1 , Figure 4 and Figure 5 As shown, the first support rod 21 and the second support rod 3 have different lengths, so that the positions of the first negative electrode plate 5 and the second negative electrode plate 2 are different, and thus the functions are also different. The first negative electrode plate 5 is used to support the bag head, and the second negative electrode plate 2 is used to support the bag body, providing different supporting forces.

[0051] Furthermore, two groups of sensing modules 8 are correspondingly arranged at the upper end of one side of the support plate 18, and the two groups of sensing modules 8 are respectively arranged corresponding to the first station and the second station, and two groups of reflecting mirrors 17 are correspondingly arranged at the lower end of one side of the support plate 18, and the two groups of reflecting mirrors 17 are arranged in upper and lower correspondence with the two groups of sensing modules 8;

[0052] Specifically, the sensing module 8 is mainly used for real-time collection of parameters of object detection data. The sensing module 8 can be a different detection method, such as an ultrasonic sensor, an infrared sensor or a touch sensor.

[0053] Preferably, the utility model adopts the sensing method of infrared sensor. When the double-chamber bag is not transported to the first station or the second station, the infrared light of the infrared sensor will be emitted to the reflector 17 below and reflected back, and the first station and the second station will not perform any work; when the infrared light emitted by the infrared sensor is blocked by the double-chamber bag and cannot be reflected back, the first station and the second station will work according to the pre-set running trajectory, thereby facilitating the first station and the second station to take action in time to detect the bag head of the double-chamber bag and collect data at the same time.

[0054] Furthermore, support columns 7 are fixedly installed at both ends of the other side of the support plate 18 to adjust the support plate 18;

[0055] For details, please refer to Figure 2 and Figure 3 ,like Figure 2 and Figure 3As shown, one end of the piston rod of the support column 7 is fixed to a place with supporting force, such as a workbench, the ground, etc. It should be noted that when the double-chamber bag is inspected, there will be liquid inside the double-chamber bag, and bubbles will inevitably appear, so that two groups of support columns 7 are started at the same time, and the angle of the device is adjusted to make the device in a tilted state to avoid the presence of bubbles in the bag head, thereby improving the detection effect of the bag head.

[0056] Preferably, the device is tilted at an angle ranging from 15° to 45°.

[0057] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
