Technical Field
[0001] The utility model relates to the technical field of film detection, in particular to a conductive brush filament. Background Art
[0002] Plastic films are used in many scenarios of industrial production. Since plastic films are made automatically by machines, they can be automatically rolled into products by machines after production. In the process of rolling them into products, relevant testing equipment will also test the plastic films to confirm whether their ingredients are toxic, that is, to determine whether there are errors in the production process. However, during the testing process, it is not convenient to test the physical indicator of whether there are holes on the surface of the plastic film.
[0003] Since the plastic film is an insulator, whether there are holes in the plastic film can be detected by detecting whether the plastic film allows current to flow from both ends thereof. Based on this, a conductive brush filament is proposed. Utility Model Content

[0006] Preferably, the adjustment assembly further comprises a sliding hole and a contact, the sliding hole is opened on both sides of the bracket, the two contacts are respectively fixedly connected to the two ends of the bracket, and the contacts are slidably connected to the inside of the sliding hole.
[0007] Preferably, the adjustment assembly further comprises a spring and a screw rod, the two springs are respectively fixedly connected between the two ends of the slide and the inner walls of the two slide grooves, the screw rod is rotatably connected to the bracket, and the screw rod is threadedly connected to the slide rod.
[0008] Preferably, the power-carrying component includes a cavity and a fixing ring, the cavity is opened inside the bracket, the two fixing rings are fixedly connected to the inner wall of the cavity, and the two ends of a brush rod are rotatably connected to the two fixing rings respectively.
[0009] Preferably, the power supply component further comprises a wire and a plug wire, the two wires are respectively fixedly connected to the two fixing rings, and the plug wire is commonly fixedly connected between the two wires.

[0011] Compared with the prior art, the utility model has the following significant advantages:
[0012] First: In the utility model, the screw is first rotated, and the slide is moved upward by the rotation of the screw. The movement of the slide drives a brush rod connected to it to move upward. At this time, a large gap is left between the two brush rods. The plastic film to be inspected is passed through the bracket, and the film is located between the two brush rods. At this time, the screw is reversed to move the slide downward, so that the brush rod connected to it is close to another brush rod, until the two brush rods are respectively against the two sides of the film. At this time, the film is moved between the two brush rods, and the film will cause the two brush rods to rotate.
[0013] Second: In the utility model, the plug cord is connected to an external power supply. At this time, current enters the plug cord and is then transmitted to the fixed ring through the wire. The fixed ring then transmits the current to the brush rod connected to it. At this time, the brush rod located below is charged. The electrical measuring device is connected to the two contacts, and the film continues to move between the two brush rods. When there are holes in the film, since the brush filaments on the two brush rods are extremely fine, the brush filaments on the two brush rods will touch at the holes. Since the brush rod below is charged, the brush rod above will also generate current on its surface after it touches. When the current is detected by the electrical measuring device, it means that there are holes in the film. BRIEF DESCRIPTION OF THE DRAWINGS
