[0002] like Figure 1 to Figure 3 As shown, the existing bottle cap 100 generally includes an inner plug 101 and an outer seal 102. When the bottle cap 100 is screwed on the bottle mouth 200, the inner plug 101 is deformed and pressed against the inner wall of the bottle mouth 200, and the outer seal 102 wraps the outer wall of the bottle mouth 200, thereby achieving sealing of the bottle mouth 200.

Due to the different uses and usage environments of the bottles, the internal pressures generated after the bottles are filled with liquids, gases and other substances are also different, which makes it difficult for manufacturers or users to quickly select a suitable bottle cap 100 to ensure the sealing of the bottle mouth 200.

[0036] In the description of this embodiment, the terms "upper", "lower", "right", etc., are based on the directions or positions shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0037] like Figure 1 to Figure 4 As shown, the present embodiment provides a bottle cap sealing detection device for detecting the sealing performance of bottle caps 100 with different structures, the bottle cap 100 comprises an inner plug 101 and an outer seal 102, when the bottle cap 100 is screwed on the bottle mouth 200, the inner plug 101 is deformed and pressed against the inner wall of the bottle mouth 200, and the outer seal 102 wraps the outer wall of the bottle mouth 200, the bottle cap sealing detection device comprises a detection member 1 and a stress detection module, the detection member 1 has a simulated bottle mouth, different types of bottle caps 100 can be selectively sealed and capped on the simulated bottle mouth to form a plurality of sealing sections, a stress detection module is arranged at the simulated bottle mouth, the stress detection module is configured to detect and output the stress distribution of the simulated bottle mouth with the bottle cap 100, so as to obtain the stress magnitude of each sealing section, and the sealing position and sealing length of the inner plug 101 and the outer seal 102 can be analyzed according to the stress magnitude. Different types of bottle caps 100 have different sealing structures. By comparing the stress distribution of different types of bottle caps 100 under the same conditions, the difference in sealing performance of different sealing structures can be accurately detected, so that the bottle cap 100 with good sealing performance can be quickly selected. In addition, under normal circumstances, the stress magnitude of the circumference at the same height along the axial direction of the simulated bottle mouth should be the same. When there is a defect in the inner plug 101 or the outer seal 102 of the bottle cap 100, the stress at the defect will suddenly change. The bottle cap sealing detection device provided by this embodiment can accurately determine the defect location, especially facilitate the discovery of tiny defects that are not easily detected by the naked eye, thereby improving the accuracy and efficiency of sealing performance detection, and facilitating the analysis and improvement of defects.

[0038] It should be noted that, in the present embodiment, the bottle cap 100 is threadedly connected to the bottle mouth 200, and in other embodiments, the connection method between the bottle cap 100 and the bottle mouth 200 includes but is not limited to a press cap connection or a snap cap connection, etc. The sealing performance of the bottle cap 100 of the above connection method can be tested by adaptively improving the simulated bottle mouth provided in the present embodiment, which will not be elaborated here.

[0039] Furthermore, the bottle cap sealing detection device also includes a detection box 2, which has a display screen 3 for displaying the stress distribution of the simulated bottle mouth of the bottle cap 100 output by the stress detection module, so that the operator can intuitively see the stress distribution diagram of the simulated bottle mouth, thereby quickly judging whether there are defects in the inner plug 101 or the outer seal 102 of the bottle cap 100.

[0040] like Figure 4 As shown, a plurality of detection members 1 can be selectively installed on the detection box 2, and the detection members 1 can be compactly installed on the detection box 2, which is beneficial to improving the appearance and user experience of the bottle cap sealing detection device, and the models of the simulated bottle mouths of at least two detection members 1 are different, so that the detection members 1 can detect the sealing of bottle caps 100 of different models, thereby improving the versatility of the bottle cap sealing detection device. In this embodiment, four detection members 1 are installed on the detection box 2, and the models of the simulated bottle mouths of each detection member 1 are different, so that the bottle cap sealing detection device can detect the sealing of bottle caps 100 of various structures corresponding to four different models of simulated bottle mouths, which can meet the actual production needs.

[0041] In order to facilitate the installation of the detection member 1, a plurality of mounting holes are provided on the detection box 2, and a plurality of detection members 1 can be detachably installed in the corresponding mounting holes, thereby limiting the detection member 1 and improving the stability of the connection between the detection member 1 and the detection box 2.

[0042] Furthermore, if Figure 5 As shown, the detection member 1 includes a connected detection portion 11 and a mounting portion 12, a simulated bottle mouth is provided on the top of the detection portion 11, and a stress detection module is arranged on the inner wall, outer wall and top of the simulated bottle mouth, which can detect the stress distribution of the inner wall, outer wall and top of the detection portion 11 in the blocked state of the bottle cap 100, and input the detected stress value to the display screen 3 to generate a simulated bottle mouth stress distribution diagram, so that the operator can intuitively and efficiently judge the sealing performance of the bottle cap 100. Specifically, the stress detection module includes a plurality of strain gauges arranged on the detection portion 11, and the plurality of strain gauges can transmit the stress values ​​detected at the positions to the control module of the bottle cap sealing detection device, and the control module outputs the stress values ​​to the display screen 3 to display the stress distribution diagram on the display screen 3. Since the control module is a prior art, the working principle of the control module is not described in detail.

[0043] Optionally, the connection method between the mounting portion 12 and the corresponding mounting hole includes, but is not limited to, threaded connection or plug-in fit, so that the connection between the detection element 1 and the detection box 2 is stable and easy to install and disassemble, which is convenient for operators to replace damaged detection elements 1 and to replace detection elements 1 of different models. In other embodiments, the connection method between the mounting portion 12 and the corresponding mounting hole can also be welding or bonding, so that the connection between the mounting portion 12 and the detection box 2 is more stable.

[0044] In actual production, due to the different uses and usage environments of the bottle, the internal pressure generated after the bottle is filled with liquid, gas and other substances is also different. Therefore, the bottle cap sealing detection device provided in this embodiment also includes a pressurizing mechanism. Figure 5 As shown, a pressurizing chamber 13 connected to the simulated bottle mouth is provided in the detection member 1, and the gas outlet end of the pressurizing mechanism is connected to the pressurizing chamber 13 of the detection member 1 to adjust the pressure in the pressurizing chamber 13, so that the stress detection module outputs the stress distribution of the simulated bottle mouth with the bottle cap 100 under different pressures, so that the operator can quickly select a suitable bottle cap 100 to seal the bottle body with a certain pressure inside. It should be noted that during the production and transportation process, the pressure in the bottle body may change due to the influence of temperature difference or shaking, so it is necessary to detect the stress distribution of the simulated bottle mouth under different pressures to ensure that the bottle cap 100 has good sealing performance from low pressure to high pressure.

[0045] Specifically, an inflation port connected to the pressurized chamber 13 is opened on the detection member 1, and the pressurizing mechanism includes an air source and multiple air pipes 4. One ends of the multiple air pipes 4 are connected to the air outlet of the air source, and the other ends of the air pipes 4 are connected to the inflation port of the detection member 1 one by one, so that the gas in the air source can enter the pressurized chamber 13 to obtain the pressure required by the operator.

[0046] Furthermore, a through first hole is opened at the bottom of the mounting hole, the first hole is connected to the inflation port, the air supply pipe 4 passes through the first hole and is connected to the inflation port, and the first hole can play a role in fixing the air supply pipe 4.

[0047] In this embodiment, since the gas source is arranged outside the detection box 2, a first hole is also opened on the detection box 2, and the gas supply pipe 4 passes through the first hole and communicates with the gas filling port of the gas source.

[0048] Furthermore, each gas delivery pipe 4 is provided with a pressure regulating valve to control the pressure of the gas input into the pressurizing chamber 13 .

[0049] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here.
