Description

TECHNICAL FIELD

[0001] The utility model relates to steel band temperature measuring device field, specifically, it relates to continuous steel band surface contact type temperature measuring device. BACKGROUND

[0002] In the manufacturing industry, the equipment taking steel band as the carrier is an indispensable part, whether it is film manufacturing, or plate manufacturing or multi-layer composite, the use of steel band equipment is indispensable. The traditional temperature measuring element has metal contact type and infrared temperature measurement, and the two kinds of temperature measurement cannot accurately detect the actual temperature of the steel band surface. The metal contact type needs to contact the steel band, but when the steel band is in the running process, the steel band and the temperature measuring element will produce friction between the metals, which will quickly damage the temperature measuring element or cause scratches on the steel band surface. And the infrared temperature measurement needs to irradiate the steel band, but the surface of the steel band is very smooth after polishing treatment, and after infrared irradiation, it is easy to cause more reflection, which reduces the reception of the infrared radiation of the temperature measuring instrument, thereby affecting the accuracy of temperature measurement.

[0024] The embodiment is used for measuring the surface temperature of the steel belt 1, mainly composed of graphite strip 2 and thermocouple 3, when the steel belt 1 is in the running process, the graphite strip 2 contacts the steel belt 1, the temperature of the steel belt 1 is transmitted to the graphite strip 2, and then the temperature is detected by the thermocouple 3, so that the actual temperature of the surface of the steel belt 1 can be accurately measured.

[0025] Specifically, as Figure 1As shown, this embodiment includes: a graphite strip 2, a thermocouple 3, a nut 4, a fixing plate 5, a square tube 6, a spring 7, a round tube 8, and a cylinder 9. The thermocouple 3 is inserted into the graphite strip 2 and installed within the fixing plate 5. The thermocouple 3 is mounted on the fixing plate 5 via the nut 4. One end of the spring 7 abuts against the fixing plate 5, and the other end abuts against the square tube 6. The spring 7 pushes the fixing plate 5 and the graphite strip 2 within it to adhere tightly to the steel strip 1.

[0026] The square tube 6 extends toward the fixed plate 5 and has multiple cylinders 9. The fixed plate 5 extends toward the square tube 6 and has multiple round tubes 8. The spring 7 and the round tubes 8 are fitted onto the cylinders 9, and the cylinders 9 are allowed to slide axially along the inner wall of the round tubes 8.

[0027] In one embodiment, the graphite strip 2 has a hole, and the rod of the thermocouple 3 is inserted into the graphite strip 2 through the hole. The gap between the rod of the thermocouple 3 and the hole of the graphite strip 2 is less than or equal to 0.1 mm.

[0029] like Figure 2 As shown, in one embodiment, the nut 4 and two round tubes 8 are welded to the fixing plate 5, forming a structure in which the graphite strip 2 is embedded. The other end of the spring 7 is fitted with a square tube 6, on which three cylinders 9 are mounted. The two cylinders 9 on either side are inserted into the two round tubes 8 as a guide mechanism, and the spring 7 is fitted onto the middle cylinder 9. The spring 7 pushes the graphite strip 2 upwards, tightly adhering it to the steel strip 1, allowing the steel strip 1 to transfer heat more quickly. Holes are drilled in the graphite strip 2, and a thermocouple 3 is inserted into them. One end of the thermocouple 3 has external threads, allowing it to be fixed in place by the nut 4. The gap between the hole in the graphite strip 2 and the thermocouple 3 rod does not exceed 0.1 mm, ensuring efficient heat transfer and thus more accurately measuring the real-time temperature of the steel strip 1 surface.
