However, the measured temperature is only the temperature inside the furnace cavity and cannot fully and truly reflect the actual temperature of the product.

[0003] In order to measure the actual temperature of the product, currently, one end of a thermocouple is usually fixed on the surface of the product, so that the thermocouple enters the annealing furnace together with the movement of the product to measure the actual temperature of the product. Due to the long length of the annealing furnace, in order for the thermocouple to follow the movement of the product, the length of the thermocouple is correspondingly long, resulting in the problem that the wire outside the furnace is prone to knotting, winding or getting stuck on other objects, leading to serious wear or even breakage of the thermocouple.

[0004] Therefore, it is necessary to provide a temperature measuring device to solve the above problems. Summary of the Utility Model

[0034] The present utility model will be further described in detail below with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present utility model, rather than limiting the present utility model. In addition, it should be noted that for the sake of description, only the parts related to the present utility model rather than all the structures are shown in the drawings.

[0035] In the description of the present utility model, unless otherwise clearly defined and limited, the terms "connected", "connected" and "fixed" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0036] In the present utility model, unless otherwise clearly specified and defined, the first feature being "above" or "below" the second feature may include direct contact between the first and second features, or may also include the situation where the first and second features are not in direct contact but in contact through additional features therebetween. Moreover, the first feature being "above", "over" and "on top of" the second feature includes the first feature being directly above and obliquely above the second feature, or simply indicating that the horizontal height of the first feature is higher than that of the second feature. The first feature being "below", "beneath" and "underneath" the second feature includes the first feature being directly below and obliquely below the second feature, or simply indicating that the horizontal height of the first feature is lower than that of the second feature.

[0037] In the description of this embodiment, the orientation or positional relationships such as "above", "below", "right", etc. are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0038] In the heat treatment technology, it is usually necessary to measure the temperature inside the furnace body to ensure that the temperature of the heat treatment reaches the requirements. However, the measured temperature is only the temperature inside the furnace cavity and cannot fully and truly reflect the actual temperature of the product. In order to be able to measure the actual temperature of the product, currently, one end of the thermocouple is usually fixed on the surface of the product, so that the thermocouple enters the annealing furnace together with the movement of the product to measure the actual temperature of the product. Since the length of the annealing furnace is relatively long, in order for the thermocouple to follow the movement of the product, the length of the thermocouple is correspondingly long, resulting in the problem that the wire outside the furnace is prone to knotting, winding or getting stuck on other objects, leading to serious wear or even breakage of the thermocouple.

[0039] To solve the above problems, as Figure 1 shown, this embodiment provides a temperature measuring device, which includes a support frame 1, a wire winding mechanism 2 and a placement box 3. The wire winding mechanism 2 is rotatably arranged on the support frame 1 around its own axis, the thermocouple is wound around the wire winding mechanism 2, the placement box 3 is arranged on the wire winding mechanism 2, one end of the thermocouple is connected to a temperature recorder, and the temperature recorder is accommodated in the placement box 3.

[0040] When measuring temperature, the other end of the thermocouple is fixed on the product. The product will enter the annealing furnace along with the mesh belt of the annealing furnace, and the thermocouple will also be brought in. The product moves into the furnace along with the mesh belt of the annealing furnace, generating a certain pulling force to pull the thermocouple, causing the winding mechanism 2 to rotate to release the thermocouple wound on it, so that the thermocouple can move into the furnace synchronously with the product. After annealing is completed, the product comes out from the furnace tail, the thermocouple is disassembled from the product, and then the winding mechanism 2 is rotated in the reverse direction, and the thermocouple can be rewound on the winding mechanism 2. Among them, the data measured by the thermocouple is displayed by a temperature recorder. The setting of the placement box 3 enables the temperature recorder to be conveniently accommodated therein, making the entire temperature measuring device more tidy and beautiful.

[0041] Compared with the prior art, the temperature measuring device provided by this embodiment winds the thermocouple on the winding mechanism 2 so that the part of the thermocouple that has not entered the furnace will not be knotted, wound or stuck on other objects, and through the winding method, the space occupied by the thermocouple can be saved. This temperature measuring device has a simple structure, is practical and effective, has a low manufacturing cost, and is easy to operate.

[0042] Specifically, as Figure 1 shown, the winding mechanism 2 includes two relatively arranged support discs 21 and a plurality of winding columns 22. The two ends of the winding column 22 are respectively fixedly connected to the two support discs 21, and the plurality of winding columns 22 are arranged in a circular pattern between the two support discs 21. The thermocouple is wound on the plurality of winding columns 22. Since the plurality of winding columns 22 are arranged in a circular shape, the thermocouple is also in a circular shape after being wound on the winding mechanism 2 and can be easily pulled out under the pull of the product. By setting the support disc 21, a stable support basis is provided for the winding column 22, and the support disc 21 usually has a certain weight, which can prevent the thermocouple from rebounding when wound on the winding mechanism 2.

[0043] In an alternative embodiment, an anti-slip layer is provided on the winding column 22. By setting the anti-slip layer, the friction between the thermocouple and the winding column 22 can be increased, preventing the thermocouple from shifting or loosening due to sliding during the winding process, and ensuring that the thermocouple can be tightly wound on the winding column 22. Specifically, the anti-slip layer is a rubber anti-slip layer or a plastic anti-slip layer.

[0044] In this embodiment, as Figure 1 shown, the placement box 3 is arranged between the two support discs 21 and is located within the circle formed by the plurality of winding columns 22. The space is effectively utilized, making this temperature measuring device more compact; and when the thermocouple is unwound or wound, it will not interfere with the placement box 3, ensuring that the thermocouple can be smoothly pulled out or rewound onto the winding mechanism 2.

[0045] Specifically, as Figure 1As shown in the figure, at least one side of the winding mechanism 2 facing the support frame 1 is provided with a first positioning hole 23, and the support frame 1 is provided with a second positioning hole 11. The winding mechanism 2 can rotate so that the first positioning hole 23 is aligned with the second positioning hole 11, and a locking member is inserted through the first positioning hole 23 and the second positioning hole 11 to limit the rotation of the winding mechanism 2. Rotate the winding mechanism 2 until the first positioning hole 23 is aligned with the second positioning hole 11, and insert the locking member through the first positioning hole 23 and the second positioning hole 11 to limit the rotation of the winding mechanism 2, that is, the winding mechanism 2 cannot rotate at this time. Through this setting, when the measuring device is idle, the winding mechanism 2 is locked, which can prevent the winding mechanism 2 from rotating under the action of external force, resulting in the release of the thermocouple wound thereon. Before measurement, remove the locking member, and it can be used normally, which is simple, fast, and convenient to operate.

[0046] In this embodiment, a first positioning hole 23 is provided on one support disk 21. In other embodiments, first positioning holes 23 are provided on both support disks 21, and correspondingly, second positioning holes 11 are also provided on both sides of the support frame 1.

[0047] Furthermore, the number of the first positioning holes 23 is multiple, and the multiple first positioning holes 23 are arranged in a circular pattern on the winding mechanism 2. The design of the multiple first positioning holes 23 enables the winding mechanism 2 to achieve multiple precise positioning points on the support frame 1. Each first positioning hole 23 can cooperate with the second positioning hole 11 on the support frame 1. By rotating the winding mechanism 2 by a small angle, one of the multiple first positioning holes 23 can be aligned with the second positioning hole 11, making the fixation of the winding mechanism 2 more efficient and rapid.

[0048] In some embodiments, as Figure 1 shown, the temperature measuring device further includes a handle 4. The handle 4 is arranged on the winding mechanism 2, and the handle 4 is shaken to make the winding mechanism 2 rotate. The design of the handle 4 enables the user to intuitively operate the winding mechanism 2 through hand movements. By shaking the handle 4 to make the winding mechanism 2 rotate in the opposite direction, the thermocouple can be rewound onto the winding mechanism 2, improving the comfort of operation. Specifically, the handle 4 is arranged on the support disk 21.

[0049] In other embodiments, the temperature measuring device further includes a driving member, and the driving member is configured to drive the winding mechanism 2 to rotate about its own axis. The driving member can drive the winding mechanism 2 to rotate to rewind the thermocouple, eliminating the need for manual driving, saving time and effort, and improving work efficiency.

[0050] Specifically, as Figure 1 shown, a plurality of moving wheels 5 are arranged at the bottom of the support frame 1. Through the moving wheels 5, the support frame 1 can be moved between different positions without laborious handling, enabling the measuring device to flexibly adjust its position according to needs, improving work efficiency, and reducing the human burden.

[0051] Furthermore, the moving wheel 5 includes a wheel body and a buckle, and the buckle can restrict the rotation of the wheel body. After the measuring device is moved to a suitable position, the buckle can be buckled to restrict the rotation of the wheel body, so that the measuring device can be fixed in a suitable position for subsequent temperature measurement operations.

[0052] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
