[0028] Referring to Figures 1-4 A TPU composite film thickness adjusting device, comprising a frame 1, a thickness gauge 2 and a drawing assembly 3.

[0029] Among them, the frame 1 is provided with a testing frame 4 for the composite film to pass through, and the testing frame 4 comprises an upper movable beam 41 and a lower movable beam 42; the upper movable beam 41 and the lower movable beam 42 are connected through two stands 43, and the upper movable beam 41, the lower movable beam 42 and the two stands 43 form a rectangular frame. The testing frame 4 can be detachably mounted on the frame 1. Specifically, the frame 1 comprises two side plates 11 and a plurality of crossbeams 12 connecting the two side plates 11. This embodiment is provided with three crossbeams 12, and the two side plates 11 are provided with a “U” type notch 13 for mounting the testing frame 4. The “U” type notch 13 is provided with a supporting assembly 14 for supporting the testing frame 4, and the supporting assembly 14 comprises a mounting plate 141 for mounting the supporting assembly 14 on the side plate 11, a supporting plate 142 vertically arranged on the top of the mounting plate 141 and a reinforcing inclined plate 143 arranged below the supporting plate 142, and the reinforcing inclined plate 143 can increase the bearing capacity of the supporting plate 14. The mounting plate 141 is fixedly mounted on the two side plates 11 by screws. The bottom of the testing frame 4 is provided with a connecting plate 45 connected with the supporting plate 142, and the connecting plate 45 is detachably connected with the supporting plate 142 by screws. The design of this embodiment that the testing frame 4 can be detachably mounted on the frame 1 makes it possible to replace the testing frame 4 with a width suitable for the composite film produced when the width of the composite film produced exceeds the inner diameter of the testing frame 4, so that the application range of the thickness adjusting device is wider.

[0030] The thickness gauge 2 is connected with a central control system of the film pasting production line. The thickness gauge 2 is used for monitoring the thickness of the TPU composite film on line, and the detection data is fed back to the central control system of the film pasting production line. The central control system controls the width of the extrusion nozzle of the extrusion mechanism, so that the thickness of the TPU composite film is monitored in real time, and the production efficiency is greatly improved, and the production cost of the enterprise is reduced. The thickness gauge 2 is an X-ray thickness gauge. The X-ray thickness gauge 2 utilizes the characteristics that the change of the intensity of X-rays is related to the thickness of the material when the X-rays penetrate the measured material, so as to measure the thickness of the material. It is a non-contact dynamic metering instrument.

[0031] In order to facilitate the on-line test of the thickness of the composite film, the thickness gauge 2 comprises an upper sensing component 21 and a lower sensing component 22, and a gap for the composite film to pass through is arranged between the upper sensing component 21 and the lower sensing component 22.

The slide rail 44 is provided with a plurality of inclined surfaces 441 on the side facing the slide block 23. The design of the plurality of inclined surfaces 441 can improve the accuracy of the movement of the thickness gauge 2.

The traction assembly 3 comprises a front traction roller 31 and a rear traction roller 32 arranged on the front and rear sides of the test frame 4. The front traction roller 31 and the rear traction roller 32 are in the same horizontal plane, and the height of the top of the two is just the same as the height of the gap between the upper sensing component 21 and the lower sensing component 22, so that the composite film can pass through the thickness gauge 2 in a horizontal state, and the detection accuracy is ensured. The composite film is pulled to the gap between the upper sensing component 21 and the lower sensing component 22 by the front traction roller 31, and then is led out by the rear traction roller 32.

[0033] Finally, it should be noted that: the above only describes the preferred embodiments of the present application, and is not used to limit the present application.
