Description

Technical Field

[0001] This utility model relates to the field of condom detection technology, specifically to a device for detecting pinholes in condoms. Background Technology

[0002] In order to prevent damaged condoms from entering the market during the condom production process, their quality needs to be tested before packaging.

[0003] Chinese patent document CN217017519U discloses a pinhole detection device for condoms. During detection, each conductive mold stays at the detection station for a set time. During this detection period, the conductive mold and the outer conductive component rotate simultaneously, similar to a gear pair transmission. Multiple outer conductive components alternately sweep across the outer surface of the condom during rotation. More preferably, the conductive mold and the outer conductive components rotate at different speeds, forming a differential mode. This ensures that after both have rotated multiple times, the outer conductive components have detected the entire surface area of ​​the condom, improving the detection accuracy.

[0004] In the above scheme, by alternately sweeping the outer conductive component across the outer surface of the condom during rotation, and by making the rotation speed of the conductive mold and the outer conductive component different, a differential mode is formed between them. During the test, if the rotation speed of the outer conductive component is too fast, friction will be generated between the outer conductive component and the outer surface of the condom when it sweeps across the outer surface of the condom, which will cause damage to the surface of the condom and affect the test results.

[0029] Example 1

[0030] like Figure 1-5 As shown, the present invention proposes a pinhole detection device for condoms, comprising a frame 1, a rotating disk 2, a mounting frame 4, and a drive assembly;

[0031] The rotating disk 2 is rotatably mounted on the top of the frame 1. The rotating disk 2 rotates on the frame 1 via a motor (not shown in the figure). Multiple outwardly inclined conductive molds 3 are rotatably connected at the top of the rotating disk 2 and near its edge.

[0032] The mounting bracket 4 is set on one side of the rotating disk 2. The side of the mounting bracket 4 is provided with a conductive component that drives the conductive mold 3 to rotate on the rotating disk 2 and cooperates with the conductive mold 3 to test the condom. During the test, the conductive component is in close contact with the condom. When the conductive component drives the conductive mold 3 to rotate, the conductive mold 3 drives the condom to roll and contact the conductive component, so that the surface of the condom is evenly stressed and avoids damage.

[0033] The drive component is located at the top of the mounting frame 4 and connected to the conductive component. It is used to drive the conductive component to rotate on the mounting frame 4 during use, and to drive the conductive mold 3 to rotate on the rotating disk 2, so that the conductive component and the conductive mold 3 rotate synchronously, thereby making the conductive component roll into contact with the condom, so that the condom can be tested.

[0034] In an optional embodiment, the bottom end of the mounting bracket 4 is hinged to the frame 1, and a cylinder 6 is provided on the side of the mounting bracket 4. The two ends of the cylinder 6 are rotatably connected to the mounting bracket 4 and the frame 1 respectively, and are used to rotate the mounting bracket 4 on the frame 1 by means of the cylinder 6 during use, thereby moving the conductive components away from and closer to the rotating disk 2.

[0035] In this embodiment, the conductive mold 3 is rotated to the side of the conductive component by the rotating disk 2 and connected to the conductive component, so that the surface of the condom is in close contact with the conductive component. At the same time, the drive component is started to drive the conductive component to rotate on the mounting bracket 4. The rotation of the conductive component drives the conductive mold 3 to rotate synchronously on the rotating disk 2. The action is similar to the meshing and rotation of gears, and the conductive mold 3 drives the surface of the condom to continuously roll and contact the conductive component, which effectively avoids surface damage caused by friction and improves the reliability of the test results.

[0036] Example 2

[0037] like Figure 4-5 As shown, the present invention proposes a pinhole detection device for condoms. Compared with the first embodiment, the difference in this embodiment is that the conductive component includes a rubber ring 5, an outer conductive component 7, and a rotating shaft 11.

[0038] The rotating shaft 11 is rotatably mounted on the other side of the mounting bracket 4 and connected to the drive assembly;

[0039] The outer conductive component 7 is fixedly installed on the outside of the rotating shaft 11 and near the top.

[0040] The rubber ring 5 is sleeved on the outside of the rotating shaft 11 and located below the outer conductive part 7, and is in rolling connection with the conductive mold 3.

[0041] In an optional embodiment, an anti-slip strip 10 is provided on the outer side of the conductive mold 3 and on the side of the rubber ring 5. There are multiple anti-slip strips 10, which are arranged at equal angles around the center of the conductive mold 3. They are used to increase the friction between the conductive mold 3 and the rubber ring 5 during use, thereby improving the effect of frictional transmission between the conductive mold 3 and the rubber ring 5.

[0042] In an optional embodiment, a connecting plate 12 is provided on the outer side of the rotating shaft 11 near the bottom end. A rubber ring 5 is sleeved on the outer side of the connecting plate 12. The diameter of the connecting plate 12 is less than or equal to the bottom diameter of the outer conductive element 7, which is used to limit the position of the outer conductive element 7 during use. At the same time, the outer dimension of the rubber ring 5 is greater than the bottom dimension of the outer conductive element 7, so that when the rotating shaft 11 drives the rubber ring 5 to contact the conductive mold 3 through the connecting plate 12, the pressure causes the rubber ring 5 to be compressed and wrapped around the outside of the anti-slip strip 10, thereby improving the effect of the rubber ring 5 driving the conductive mold 3.

[0043] In an optional embodiment, a locking block 13 is provided on the outer circular surface of the connecting disk 12, and a locking groove 14 is provided on the inner side of the rubber ring 5. When the rubber ring 5 and the connecting disk 12 are installed together, the locking block 13 is accommodated in the locking groove 14 to limit the rotation of the rubber ring 5 during use, so as to prevent the rubber ring 5 from rotating on the connecting disk 12, which would prevent the rubber ring 5 from driving the conductive mold 3 to rotate.

[0044] In this embodiment, the drive component drives the rotating shaft 11 to rotate, and the rotation of the rotating shaft 11 is transmitted to the rubber ring 5 through the connecting plate 12. This causes the rubber ring 5 to drive the conductive mold 3 to rotate synchronously, and at the same time, the outer conductive component 7 rotates synchronously with the conductive mold 3. This ensures that the surface of the condom on the conductive mold 3 is in continuous rolling contact with the outer conductive component 7, ensuring that there are no missed detections during the detection process, improving the overall detection accuracy and efficiency, and avoiding friction between the outer conductive component 7 and the condom, which could cause damage to the surface of the condom.

[0045] Example 3

[0046] like Figure 1 and Figure 4 As shown, the present invention proposes a pinhole detection device for condoms. Compared with the first embodiment, the difference in this embodiment is that the driving component includes a motor 8 and a transmission structure 9.

[0047] The motor 8 is mounted on the side of the mounting bracket 4. The motor 8 can rotate in both directions to prevent the wires from getting tangled.

[0048] The transmission structure 9 is installed at the ends of the output shaft of the motor 8 and the rotating shaft 11. The transmission structure 9 is one of chain drive, belt drive and gear drive.

[0049] In this embodiment, the motor 8 starts and drives the transmission structure 9 to operate, and the power is transmitted to the rotating shaft 11 through the transmission structure 9, so that the rotating shaft 11 and the transmission structure 9 rotate synchronously. This drives the rubber ring 5 to drive the conductive mold 3 to rotate synchronously, ensuring that the surface of the condom and the outer conductive part 7 continue to roll in contact, improving the detection accuracy and preventing damage to the surface of the condom caused by friction.

[0050] In this invention, a condom is placed on a conductive mold 3, and the conductive mold 3 is rotated to the side of the outer conductive component 7 by a rotating disk 2. The conductive mold 3 and the anti-slip strip 10 are brought into contact with the rubber ring 5, and the surface of the outer conductive component 7 is made to fit tightly against the condom. At the same time, the motor 8 is started to drive the transmission structure 9 to rotate, so that the transmission structure 9 transmits power to the rotating shaft 11, so that the rotating shaft 11 and the transmission structure 9 rotate synchronously. At the same time, the rotating shaft 11 transmits the rotational power to the rubber ring 5 through the connecting disk 12, so that the rubber ring 5 drives the conductive mold 3 to rotate synchronously and in opposite directions through its own characteristics and the cooperation of the anti-slip strip 10. This makes the conductive mold 3 cause the condom to continuously roll and contact the surface of the outer conductive component 7, ensuring no missed detections during the detection process, improving the overall detection accuracy and efficiency, and avoiding friction between the outer conductive component 7 and the condom, which could cause damage to the surface of the condom.

[0051] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
