DETAILED DESCRIPTION

[0028] In order to make the purpose, technical scheme and advantages of the present application more clear, the technical scheme of the present application will be described in detail below. Obviously, the described embodiments are only some embodiments of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of the present application.

It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally of a kind and do not limit the number of objects, for example, the first object can be one or more. In addition, "and / or" in the specification and claims indicates at least one of the connected objects, and the character " / ", generally indicates that the objects before and after are in a "or" relationship.

[0030] The embodiments of the present application disclose a high-pressure discharge engagement detection device for the head of an infusion bottle and an infusion bottle leakage detection equipment. Figures 1 to 5 The high-pressure discharge engagement detection device for the head of an infusion bottle and the infusion bottle leakage detection equipment provided by the embodiments of the present application will be described in detail through specific embodiments and application scenarios.

[0031] Please refer to Figure 1 The embodiments of the present application disclose a high-pressure discharge engagement detection device for the head of an infusion bottle, which comprises a support 100, a first electrode 200 and a driving mechanism 300. The support 100 is the basic component of the entire high-pressure discharge engagement detection device for the head of an infusion bottle, which can provide a mounting basis for the first electrode 200 and the driving mechanism 300. For example, the support 100 can be a plate structure. The first electrode 200 is rotatably arranged on one side of the support 100, and the driving mechanism 300 is arranged on the other side of the support 100. The driving mechanism 300 is in transmission connection with the first electrode 200 to drive the first electrode 200 to rotate.

[0032] In the embodiments of the present application, please continue to refer to Figure 1 The number of the first electrodes 200 is two, and the two first electrodes 200 are oppositely and adjacently arranged. A detection area for the head 610 of the infusion bottle 600 to pass through is formed between the two first electrodes 200. The head 610 of the infusion bottle 600 can pass through the detection area under the conveying of the conveying chain. The driving mechanism 300 drives the two first electrodes 200 to synchronously and reversely rotate, so as to ensure that the head 610 can smoothly pass through and avoid the situation of collision and bottle jamming. In the process of the head 610 passing through the detection area, the two first electrodes 200 can discharge the head 610 to perform leakage detection.

[0033] Specifically, please refer to Figure 1 and Figure 2The first electrode 200 comprises a wheel body 210, and the wheel body 210 is provided with a plurality of tooth portions 211 distributed along the circumferential direction of the wheel body 210, and each two adjacent tooth portions 211 have an inwardly recessed discharge surface 212. When the infusion bottle 600 passes through the detection area, the bottle head 610 of the infusion bottle 600 is accommodated in the recessed position of the two first electrodes 200, and the discharge surfaces 212 of the two first electrodes 200 are opposite to each other and wrap around the bottle head 610 of the infusion bottle 600. As the infusion bottle 600 continues to be conveyed, the driving mechanism 300 drives the two first electrodes 200 to synchronously and reversely rotate to adapt to the position change of the bottle head 610.

[0034] Based on the above technical scheme, when the bottle head 610 of the infusion bottle 600 is conveyed to the detection area between the two first electrodes 200, the bottle head 610 can be located in the area enclosed by the two discharge surfaces 212, the discharge surfaces 212 can be close to the outer circumferential portion of the bottle head 610, and the continuous discharge of the two discharge surfaces 212 can form a stable electric field distribution and comprehensively detect the circumferential side of the bottle head 610, thereby ensuring the accuracy of the detection result, and having the characteristics of convenient detection and high accuracy.

[0035] In the embodiment of the present application, please continue to refer to Figure 1 The driving mechanism 300 can comprise a motor 310, a first gear 320 and a second gear 330, wherein the first gear 320 and the second gear 330 are meshed with each other, the two first electrodes 200 are connected to the first gear 320 and the second gear 330 through a connecting shaft 340, and the motor 310 is connected to one of the first gear 320 and the second gear 330 to drive the two first electrodes 200 to synchronously and reversely rotate. It can be understood that the motor 310 is connected to the first gear 320 or the second gear 330, which can be directly connected or indirectly connected through an intermediate transition gear, and the present application does not make a specific limitation thereon. Through the transmission mode of the meshing of the first gear 320 and the second gear 330, the synchronous and reverse rotation of the two first electrodes 200 can be realized by one motor 310, thereby optimizing the space occupation of the driving mechanism 300.

[0036] In the embodiment of the present application, please continue to refer to Figure 1 The first electrode 200 further comprises a sleeve 220 integrally connected with the wheel body 210, the sleeve 220 is sleeved on the connecting shaft 340 and connected and fixed through a threaded connecting piece. For example, a threaded hole is formed in the side wall of the sleeve 220, the threaded connecting piece is threadedly connected in the threaded hole, and abuts against the circumferential wall of the connecting shaft 340 to realize the connection and fixation of the first electrode 200 and the connecting shaft 340. Of course, in a further technical scheme, the threaded connecting piece can also be locked on the end face of the connecting shaft 340 to reinforce the connection stability of the first electrode 200 and the connecting shaft 340.

[0037] It can be understood that the first electrode 200 in the embodiment of the application is connected with a power supply, and the first electrode 200 is connected with the power supply through a wire for example. In a further technical solution, the infusion bottle neck high-voltage discharge engagement detection device further comprises an electrically conductive element 400, which can be a metal guide rod. The electrically conductive element 400 is electrically connected with the two first electrodes 200, and one of the two first electrodes 200 is connected with the power supply. In this way, the problem of increased connection points caused by connecting each first electrode 200 with the power supply separately can be avoided. In the case of increased connection points, the probability of loose connection points and poor contact increases, thereby affecting the stability of detection. In the embodiment of the application, the two first electrodes 200 are electrically connected through the metal guide rod, so that the problem of increased connection points can be avoided, thereby ensuring the stability of detection work. The discharge surfaces 212 of the two first electrodes 200 can discharge at the same time, and can cover the entire periphery of the neck 610 of the infusion bottle 600, so as to realize comprehensive and dead-angle-free detection, which is helpful to find small defects and flaws of the neck 610 and improve the accuracy of detection to ensure product quality.

[0038] In a further technical solution, the discharge surface 212 is a circular arc surface, and the radius of the discharge surface 212 is greater than the radius of the neck 610 of the infusion bottle 600. In this way, when the neck 610 of the infusion bottle 600 is surrounded by the two discharge surfaces 212, there is a gap between the discharge surface 212 and the peripheral wall of the neck 610. On the one hand, the gap can prevent direct contact between the discharge surface 212 and the peripheral wall of the neck 610, thereby avoiding damage to the neck 610 caused by extrusion. On the other hand, when the discharge surface 212 discharges, when the electric field strength in the gap reaches a certain degree, gas molecules will be ionized to form a discharge channel, thereby generating a discharge phenomenon, so as to ensure normal discharge detection.

[0039] It should be noted that in the related art, the cross-sectional shape of the neck 610 of the infusion bottle 600 is usually circular, so the discharge surface 212 can be a circular arc surface as described above. It can be understood that if the cross section of the neck 610 of the infusion bottle 600 is of other shapes, such as rectangular, elliptical, etc., the shape of the discharge surface 212 is adapted to the outer peripheral contour of the neck 610.

[0040] In a further technical solution, in the case where the discharge surface 212 is a circular arc surface, the central angle corresponding to the discharge surface 212 is less than 180°. The design of the circular arc surface with a central angle less than 180° makes the two discharge surfaces 212 have a larger opening. When the neck 610 of the infusion bottle 600 slowly enters between the two discharge surfaces 212, even if the position and size of the neck 610 deviate slightly, the neck 610 will not directly collide and jam with the first electrode 200, thereby protecting the integrity of the neck 610 and the first electrode 200.

[0041] In the embodiment of the present application, the infusion bottle neck engaging device further comprises a second electrode 500, which is fixedly arranged relative to the support 100, and is used to contact the bottle body of the infusion bottle 600. For example, the second electrode 500 can be in the form of an electric brush or an elastic electrode sheet. When the bottle neck 610 is intact, the infusion bottle 600 acts as an insulator, and a capacitance is formed between the first electrode 200 and the second electrode 500. The capacitance value between the first electrode 200 and the second electrode 500 is relatively large, and the induced micro-current generated is relatively small. When the bottle neck is damaged and leaks, the capacitance formed between the infusion bottle 600 and the first electrode 200 and the second electrode 500 disappears or decreases. At this time, a loop is formed between the first electrode 200 and the second electrode 500, and the current can directly flow to the negative electrode brush through the leakage, resulting in an increase in the micro-current. The micro-current generated can be measured by the detection circuit to determine whether the infusion bottle 600 leaks at the bottle neck.

[0042] Please refer to Figure 4 and Figure 5 The embodiment of the present application further discloses an infusion bottle leakage detection device. The disclosed infusion bottle leakage detection device comprises the infusion bottle neck high-voltage discharge engaging detection device described above.

[0043] It should be noted that in this document, the terms "comprising", "containing" or any other variant thereof are intended to cover non-exclusive inclusions, so that a process, method, article or device that includes a series of elements not only includes those elements, but also includes other elements not explicitly listed or inherent to such a process, method, article or device. Without more limitations, the element defined by the statement "comprising a" does not exclude the presence of another identical element in the process, method, article or device that includes the element. In addition, it should be noted that the scope of the methods and devices in the embodiments of the present application is not limited to performing functions in the order shown or discussed, but can also include performing functions in a substantially simultaneous manner or in reverse order, for example, the described method can be performed in an order different from that described, and various steps can also be added, omitted or combined.
