Example 1

Please refer to FIG. 1 to FIG. 5 , this embodiment provides a technical solution: a plastic film flattening detection device, comprising a supporting bottom plate 1 , and the left and right sides of the supporting bottom plate 1 are provided with vertical The chute 10 , the limiting rods 11 are fixedly installed between the left and right sides of the support base plate 1 , the support base plate 1 is provided with a flatness detection device 2 , and the flatness detection device 2 includes the left and right side plates of the support base plate 1 . The first conveying roller 20 and the second conveying roller 21 arranged above the first conveying roller 20 are rotatably connected with each other, and both ends of the second conveying roller 21 are rotatably connected with a fixed sleeve 23, and the fixed sleeve 23 is located in the Inside the chute 10 and slidingly connected with the chute 10, a comparison plate 25 is arranged above the second conveying roller 21, and the comparison plate 25 is slidably connected with the limit rod 11, and the surface of the comparison plate 25 is provided There is a flat marking line 251 to ensure that when the plastic film passing between the first conveying roller 20 and the second conveying roller 21 is not flat, the raised plastic film will push the second conveying roller 21 upward. , the upward movement of the second conveying roller 21 can drive the comparison plate 25 to move upward, and the upward movement of the comparison plate 25 will expose the flat marking line 251, indicating that the plastic film is not flat enough, which is convenient for use.

In this embodiment, the limit rod 11 is provided with a sliding hole 111 along the length direction of the limit rod 11 , and the comparison plate 25 is located in the sliding hole 111 and is slidably connected with the sliding hole 111 . Sliding in the sliding hole 111 ensures that the comparison plate 25 can normally slide on the limiting rod 11 .

Specifically, the flat marking line 251 is located in the sliding hole 111, so that under normal circumstances, the flat marking line 251 will not be exposed. When the flatness of the plastic film is abnormal, it can drive the comparison plate 25 to move. At this time, the flat marking line 251 can be moved. The line 251 is exposed to facilitate the flatness detection operation.

Further, a rotating shaft 22 is fixedly installed on both end rod bodies of the first conveying roller 20 and the second conveying roller 21, a bearing 221 is fixedly installed on the rotating shaft 22, the rotating shaft 22 is fixedly installed on the inner ring of the bearing 221, and the bearing 221 is fixed.
