[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Example 1:

[0032] Please see Figure 1-4 In this embodiment, the present invention provides:

[0033] A material thickness testing device includes a first winding and unwinding support 3, a second winding and unwinding support 4, and a thickness gauge structure 2. The first winding and unwinding support 3 and the second winding and unwinding support 4 are respectively arranged on both sides of the thickness gauge structure 2. The thickness gauge structure 2 includes a crossbeam assembly structure and an upper and lower probe assembly. The upper and lower probe assembly is fixed inside the crossbeam assembly structure. The crossbeam assembly structure includes an upper crossbeam 21, a lower crossbeam 22, and a fixing frame 23 that fixes the upper crossbeam 21 and the lower crossbeam 22 on both sides. The upper probe 24 in the upper and lower probe assembly is located on the upper crossbeam 21, and the lower probe 25 in the upper and lower probe assembly is located on the lower crossbeam 22. The upper probe 24 is an X-ray receiving end, and the lower probe 25 is an X-ray emitting end. Both the upper probe 24 and the lower probe 25 are covered by a metal shell 9.

[0034] The material is placed on the second take-up and unwinding bracket 4 and pulled to the first take-up and unwinding bracket 3 by the thickness gauge structure 2. The thickness of the material can be accurately measured by the X-ray emission and reception of the X-ray receiver in the upper probe 24 and the X-ray emitter in the lower probe 25 of the thickness gauge structure 2. The metal cover 8 protects the upper probe 24 and the lower probe 25.

[0035] Appendix Figure 5 , 7 In section 9, the first take-up and unwind bracket 3 includes a first bottom bracket 31, a first scale bracket 33 is provided on the inner side of the first bottom bracket 31, a first vertical scale bracket 32 ​​is installed on the front side, a first horizontal axis 34 is provided between the first vertical scale brackets 32 through an up-down adjustment structure, a first adjusting roller 36 is movably connected to the first horizontal axis 34 through a first adjusting roller support seat 35, and a first take-up roller 37 is connected to the first scale bracket 33 through a front-back adjustment structure.

[0036] Appendix Figure 6 , 8 In section 10, the second take-up and unwind bracket 4 includes a second bottom bracket 41, a second scale bracket 43 is provided on the inner side of the second bottom bracket 41, a second vertical scale bracket 42 is installed on the front side, a second horizontal shaft 44 is provided between the second vertical scale brackets 42 through an up-down adjustment structure, a second adjusting roller 46 is movably connected to the second horizontal shaft 44 through a second adjusting roller support 45, and a second take-up roller 47 is connected to the second scale bracket 43 through a front-back adjustment structure.

[0037] In the above technical solution, the first adjusting roller 36 is movably fixed on the first horizontal shaft 34 by the first adjusting roller support 35, and the second adjusting roller 46 is movably fixed on the second horizontal shaft 44 by the second adjusting roller support 45. The movable fixing is achieved by screws and spring nuts. By adjusting the position of the spring nuts on the first horizontal shaft 34 or the second horizontal shaft 44, the left and right adjustment of the first adjusting roller 36 and the second adjusting roller 46 can be realized.

[0038] The height of the first adjusting roller 36 or the second adjusting roller 46 on the first horizontal axis 34 or the second horizontal axis 44 can be adjusted by the up-down adjustment structure, so as to make the material passing through taut. The front-back adjustment structure can adjust the front-back position of the first winding roller 37 or the second winding roller 47, which can also make the material taut.

[0039] The vertical adjustment structure includes a corner bracket 51 movably connected to the first vertical scale support 32 / second vertical scale support 42, and a first spring nut 52 and a first screw 53 for adjustment. The corner bracket 51 has two fixed positions. One position is connected to the bottom of the first horizontal axis 34 or the second horizontal axis 44 by a cylindrical head screw, and the other end is connected to the first vertical scale support 32 or the second vertical scale support 42 by the first screw 53 and the first spring nut 52. By adjusting the first screw 53 and the first spring nut 52, the vertical adjustment of the first horizontal axis 34 and the second horizontal axis 44 can be realized, that is, the vertical position adjustment of the first adjusting roller 36 or the second adjusting roller 46 can be realized. Whether the heights of the two ends of the first adjusting roller 36 or the second adjusting roller 46 are consistent can be determined by the scale display on the first vertical scale support 32 or the second vertical scale support 42.

[0040] When adjusting the first adjusting roller 36 or the second adjusting roller 46, the heights of the two rollers must be consistent so that the roll material can pass flat through the middle of the upper and lower probe assembly.

[0041] The front and rear adjustment structure includes ball bearings 61 installed on both sides of the first take-up roller 37 / second take-up roller 47, and a take-up roller bracket 62 connected to the ball bearings 61. The take-up roller bracket 62 is fixed on the second scale bracket 43 by the second spring nut 63 and the second screw 64.

[0042] The first take-up roller 37 or the second take-up roller 47 is movably connected to the take-up roller bracket 62 via ball bearing 61. The take-up roller bracket 62 is connected to the second scale bracket 43 via the second spring nut 63 and the second screw. The second spring nut 63 and the second screw 64 allow the first take-up roller 37 and the second take-up roller 47 to move back and forth on it, and their left and right positions can be displayed according to the scale on the second scale bracket 43, thus preventing the first take-up roller 37 and the second take-up roller 47 from moving in an inclined state.

[0043] The first take-up roller 37 and the second take-up roller 47 are controlled by the take-up and untake-up motor 7, which is mounted on one of the take-up and untake-up supports.

[0044] The bottom of the first winding and unwinding support 3, the second winding and unwinding support 4, and the thickness gauge structure 2 are equipped with a ferrule 8.

[0045] After the positions of the first winding bracket 3, the second winding bracket 4, and the thickness gauge structure 2 are adjusted, the Foma wheel 8 is locked to prevent changes in their positions. When the material is not tensioned enough, the position can also be adjusted by the Foma wheel 8 to make the material tensioned.

[0046] During operation, the roll material is placed on the take-up and unwind bracket equipped with motor 7. According to the attached diagram in the instruction manual, the roll material is placed on the second take-up and unwind bracket 4. During this process, the roll material is slid over the first adjusting roller 36, the upper and lower probe assembly, and the second adjusting roller 46, pulling the material onto the first take-up and unwind bracket 3. The first adjusting roller 36 and the second adjusting roller 46 are adjusted to make their heights consistent. The front and rear positions of the first take-up and unwind bracket 3 and the second take-up and unwind bracket 4 are adjusted to make the roll material being tested taut. After power is applied, the thickness of the roll material is measured by X-rays emitted between the upper probe 24 and the lower probe 25.

[0047] Example 2

[0048] Appendix Figure 11 In the middle, a material placement plate 26 passing through the upper and lower probe assembly is placed between the first adjusting roller 36 and the second adjusting roller 46, and a pressure block 27 is provided on the material placement plate 26.

[0049] If the material to be measured is a cut material, the material can be placed flat on the material placement plate 26, stretched flat with the pressure block 27, placed on the first adjusting roller 36 and the second adjusting roller 46, and passed through the gap between the upper and lower probe assembly. After the fuma wheel 8 is self-locked, after power is turned on, the upper and lower probe assembly is used to move back and forth to measure the thickness of the material.
