[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] like Figures 1 to 4 As shown, an electromagnetic induction heating roller with temperature detection function includes an electromagnetic induction heating roller body 1. Multiple temperature detection units are connected to the outer side of the electromagnetic induction heating roller body 1. Each temperature detection unit consists of a temperature detection display unit 2 and a temperature detection sensing unit 21. The temperature detection sensing unit 21 is attached to the outer wall of the electromagnetic induction heating roller body 1. A slider 8 is connected to the back of the temperature detection sensing unit 21. A fixing rod 6 is connected between the multiple temperature detection units. The multiple sliders 8 are slidably connected to the fixing rod 6.

[0022] like Figure 1 As shown, the electromagnetic induction heating roller with temperature detection function in this utility model is similar in structure to existing rollers using electromagnetic induction heating, such as the roller using electromagnetic induction heating disclosed in patent publication number CN213661999U. The main improvement of this utility model is that it has a temperature detection device on the outer surface of the heating roller, so as to provide feedback on the temperature at multiple points on the outer surface of the heating roller, such as... Figures 1 to 4 As shown, when the electromagnetic induction heating roller with temperature detection function in this utility model is in use, when the electromagnetic induction heating roller body 1 is working, the temperature detection sensing unit 21 in the temperature detection unit can be attached to the outer wall of the electromagnetic induction heating roller body 1. The temperature of the temperature detection sensing unit 21 will be displayed through the temperature detection display unit 2. This setting makes it convenient for people to detect the temperature on the outside of the roller. Since there are multiple temperature detection units, it is convenient to perform multi-point temperature detection on the outside of the roller, so as to detect whether the heating on the outside of the roller is uniform.

[0023] Meanwhile, the arrangement of slider 8 and fixed rod 6 facilitates the movement of individual temperature detection units, making it easier to select detection points and improving flexibility.

[0024] The temperature detection temperature sensing unit 21 can realize accurate monitoring of the temperature of the outer surface of the electromagnetic induction heating roller body 1. The arrangement of multiple temperature detection units enables multi-point temperature detection on the outer side of the roller body, ensuring comprehensive coverage and accurate assessment of uniform heating. The temperature detection display unit 2 presents real-time temperature data, providing operators with intuitive and clear temperature distribution information. This design improves the accuracy and reliability of temperature monitoring, facilitates timely detection and resolution of uneven heating issues, and helps optimize production processes and product quality. The slider 8 and fixed rod 6 can facilitate the movement of individual temperature detection units, making it easier to select detection points and improving flexibility.

[0025] It is worth noting that the temperature detection temperature sensing unit 21 and the temperature detection display unit 2 in the temperature detection unit are both existing mature technologies. The temperature detection temperature sensing unit 21 should be selected according to the specific application scenario and requirements, such as contact-type thermocouples or thermal resistors, and non-contact infrared thermometers, aiming to detect the temperature of the outer surface of the electromagnetic induction heating roller body 1. All of the above are existing mature technologies, so they will not be described in detail here.

[0026] As shown in Figure 1 , Figure 2 and Figure 3 , the two ends of the fixed rod 6 are connected with L-shaped brackets 4, the outer ends of the horizontal rods of the L-shaped brackets 4 are fixedly connected with mounting plates 9, and mounting holes 91 are formed in the mounting plates 9.

[0027] Specifically, the L-shaped brackets 4 can facilitate the installation and support of the fixed rod 6, and the mounting plates 9 and mounting holes 91 can facilitate the installation of the L-shaped brackets 4.

[0028] It is worth noting that the movement of the L-shaped brackets 4 and the mounting plates 9 depends on the specific conditions of the electromagnetic induction heating roller body 1, aiming to install the fixed rod 6 so that the temperature detection unit can be reasonably located on the outer side of the electromagnetic induction heating roller body 1.

[0029] As shown in Figure 3 , the top of the L-shaped bracket 4 is rotatably connected with a mounting end shaft 10, the mounting end shaft 10 passes through one end of the L-shaped bracket 4 and is connected with the fixed rod 6, and the outer wall of one of the L-shaped brackets 4 is fixedly connected with a base 42, the base 42 is fixedly installed with a motor 5, and the output end of the motor 5 is fixedly connected with the mounting end shaft 10.

[0030] Specifically, in order to make the temperature detection temperature sensing unit 21 of the temperature detection unit away from the electromagnetic induction heating roller body 1 when not in use, the motor 5 can be started, the output shaft of the motor 5 drives the mounting end shaft 10 to rotate in the L-shaped bracket 4, drives the fixed rod 6 connected thereto to rotate, and drives multiple temperature detection units to rotate, so that the temperature detection temperature sensing unit 21 is away from the outer surface of the roller body.

[0031] As Figure 3 shown, the two ends of the fixed rod 6 are provided with rectangular grooves 61, and the end portions of the mounting end shafts 10 are fixedly connected with rectangular insertion rods 11 inserted into the rectangular grooves 61.

[0032] Specifically, in order to facilitate the disassembly and assembly of the fixed rod 6, and to facilitate the increase or decrease of the temperature detection units, the L-shaped support 4 can be disassembled, so that the L-shaped support 4 drives the mounting end shafts 10 to move away from the fixed rod 6, and the rectangular insertion rods 11 are separated from the rectangular grooves 61, so that the fixed rod 6 can be conveniently increased or decreased in the number of temperature detection units connected with the sliding blocks 8.

[0033] As Figure 3 shown, the fixed rod 6 is a rectangular rod. The rectangular rod-shaped fixed rod 6 makes the sliding adjustment of the sliding blocks 8 stable.

[0034] As Figure 3 shown, the horizontal rod and the vertical rod of the L-shaped support 4 are fixedly connected with an inclined support 41. The inclined support 41 can improve the stability of the L-shaped support 4.

[0035] As Figure 1 , Figure 2 and Figure 4 shown, the two L-shaped supports 4 are fixedly connected with a heat dissipation unit. The heat dissipation unit comprises a heat dissipation mounting shell 3, a plurality of mounting grooves are formed in the heat dissipation mounting shell 3, a plurality of fans 31 are fixedly connected in the mounting grooves, and filter screens 7 for filtering are connected to the outer walls of the mounting grooves.

[0036] Specifically, when the plurality of temperature detection units are rotated to a certain angle, they will enter the heat dissipation mounting shell 3, and the fans 31 will be started, so that the natural wind will be sent into the heat dissipation mounting shell 3, which can accelerate the air flow, so that the temperature detection temperature sensing unit 21 can be cooled faster, and the service life thereof can be effectively improved.

[0037] In the above structure, the motor 5 and the fan 31 are both existing mature technologies, so they will not be described in detail here.

[0038] Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement to part of the technical features, and any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the utility model shall be included in the protection scope of the utility model.
