Description

Technical Field

[0001] The utility model relates to the technical field of X-ray thickness gauges, in particular to a window structure of an X-ray thickness gauge emission head. Background Art

[0002] X-ray thickness gauge uses the property that when X-rays penetrate the material, the change in X-ray intensity is related to the thickness of the material, so as to measure the thickness of the material. It is a non-contact dynamic measuring instrument.

[0003] At present, most of the X-ray thickness gauges on the market are composed of two parts: a receiving head located at the top and a transmitting head located at the bottom. Generally, the window of the transmitting head at the bottom is a concave structure. When the X-ray thickness gauge measures the thickness of ultra-thin aluminum foil strips, due to the oil on the surface of the ultra-thin aluminum foil strips, the protective oil on the aluminum foil strips is easy to form an oil film on the measuring window of the transmitting head at the bottom of the thickness gauge, or the accumulation of dirt (aluminum oxide) on the measuring window affects the measurement accuracy of the thickness gauge and causes the problem of low yield rate in the production of ultra-thin aluminum foil strips. In order to ensure the measurement accuracy of the thickness gauge and thus ensure the yield rate of aluminum foil strips produced by users, an air purge device for the thickness gauge window film is proposed.

[0025] See also Figures 1 to 5 In an embodiment of the utility model, an X-ray thickness gauge transmitting head window structure includes an X-ray thickness gauge body 5, the X-ray thickness gauge body 5 includes a thickness gauge receiving head 1 and a thickness gauge transmitting head 2, a mounting plate 3 is installed on the upper side of the thickness gauge transmitting head 2 through a plurality of first bolts 6, a through hole 13 is opened in the center of the mounting plate 3, the through hole 13 is located directly above the measuring window of the thickness gauge transmitting head 2, a pressure ring groove 8 is opened on the upper side of the mounting plate 3, the shape of the pressure ring groove 8 is the same as that of the pressure ring plate 4, the cross-section of the pressure ring plate 4 is L-shaped, the pressure ring plate 4 is installed in the pressure ring groove 8 through a plurality of second bolts 9, a circular window membrane 7 is laid in the center of the surface of the pressure ring groove 8, and the ring edge of the window membrane 7 is clamped between the pressure ring plate 4 and the pressure ring groove 8.

[0026] Specifically, a first sealing ring groove 12 is opened on the bottom side wall of the pressure ring groove 8, and a first sealing ring 10 is arranged in the first sealing ring groove 12. The cross-section of the first sealing ring 10 is set in an X shape. The first sealing ring groove 12 extends from the upper side of the first sealing ring 10 to abut against the window film 7. The first sealing ring 10 is located between the window film 7 and the first sealing ring groove 12, which can play a sealing role.

[0027] Specifically, a second sealing ring groove 11 is opened on the bottom side wall of the mounting plate 3, and a second sealing ring 14 is arranged in the second sealing ring groove 11. The bottom side of the second sealing ring 14 extends out of the second sealing ring groove 11 and abuts against the upper side of the thickness gauge transmitter head 2. The second sealing ring 14 and the first sealing ring 10 are both made of rubber material. The second sealing ring 14 is placed between the mounting plate 3 and the thickness gauge transmitter head 2, which can improve the sealing between the mounting plate 3 and the thickness gauge transmitter head 2.

[0028] The working principle of the utility model is:

[0029] During installation, first press the mounting plate 3 onto the upper side of the thickness gauge transmitting head 2 through the first bolt 6, and place a second sealing ring 14 between the mounting plate 3 and the thickness gauge transmitting head 2 to ensure the sealing between the mounting plate 3 and the thickness gauge transmitting head 2. Then place the window film 7 at the upper central position of the mounting plate 3, and place the first sealing ring 10 in the first sealing ring groove 12 to ensure the sealing between the window film 7 and the mounting plate 3. Then, install and fix the pressure ring plate 4 in the pressure ring groove 8 through the second bolt 9. The pressure ring plate 4 can press and fix the edge of the window film 7 in the pressure ring groove 8 to ensure the stable position of the window film 7.

[0030] This solution not only ensures the sealing of the measuring window of the thickness gauge transmitter head 2, but also the position of the window film 7 is basically flush with the position of the pressure ring plate 4. This structure effectively avoids the situation in which the aluminum foil strip is brought to the thickness gauge head to form an oil film on the measuring window, or dirt is accumulated on the measuring window during use. This ensures the measurement accuracy of the thickness gauge and further achieves the purpose of improving the yield rate of aluminum foil strips.
