Technical Field

[0001] The utility model relates to a pendulum impact measuring device for detecting the impact force of printed packaging films, belonging to the technical field of film detection equipment. Background Art

[0002] When the printed flexible packaging film is produced, it forms a finished product after processes such as printing, lamination, inkjet coding, and slitting. After the printed flexible packaging film is made into a finished product, the impact resistance of the packaging film will be detected, and this uses a pendulum impact measuring device. The current pendulum impact measuring device includes a pendulum impact measuring instrument body and a chassis. Then, two pairs of pinch rollers are arranged on the chassis. The pinch rollers clamp the packaging film to be tested. By placing the rolled packaging film on the two pairs of pinch rollers and pulling the packaging film, the test position can be changed in segments. However, since the pinch rollers are rotationally clamped, the packaging film is prone to looseness during the test, affecting the test results. Moreover, there is no winding and broken part of the packaging film roll, and it is not easy to place the packaging film roll. Content of the Utility Model

[0003] The utility model provides a pendulum impact measuring device for detecting the impact force of printed packaging films, which solves the problem that the upper film and the lower film on the current laminator are prone to looseness before entering the hot press pair rollers, affecting the hot press lamination effect.
