Description

TECHNICAL FIELD

[0001] The utility model relates to temperature control device technical field, concretely is a kind of auxiliary temperature control device for electromagnetic induction heating roller. BACKGROUND

[0002] Electromagnetic induction heating roller is a kind of heating equipment widely used in rubber, plastic, papermaking and other industries, and its working principle is based on electromagnetic induction principle. Specifically, when alternating current passes through the induction coil wound around the non-ferromagnetic material roller body, an alternating magnetic field is generated around these coils. This magnetic field can penetrate into the metal roller body and induce eddy currents. Because of the resistance in the metal material, eddy currents will generate Joule heat during flow, thereby realizing the conversion of electric energy into heat energy, and the roller body itself is heated.

[0003] In order to ensure the stability and accuracy of the heating process, electromagnetic induction heating roller usually needs to be equipped with auxiliary temperature control device. These devices include temperature sensor, controller and power regulator. The temperature sensor is responsible for detecting the temperature of the roller body and transmitting the signal to the controller. The controller adjusts the power regulator to control the size of the alternating current in the induction coil according to the received temperature signal. When the temperature sensor detects a change in the temperature of the roller body, the controller will adjust the power regulator accordingly, thereby changing the current size of the induction coil to achieve accurate control of the temperature of the roller body.

[0004] Although the current size of the induction coil can be effectively controlled by the controller and the power regulator to control the temperature of the roller body, this control method has limitations in terms of cooling. Specifically, when the temperature of the roller body is too high, the controller will instruct the power regulator to reduce the current of the induction coil, thereby reducing the heating intensity of the roller body. However, at this time, the temperature of the roller body mainly depends on its own heat dissipation capacity and cannot be quickly reduced to an appropriate level. Therefore, this temperature control method may not be flexible and efficient in some cases. SUMMARY

[0022] 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.

[0023] Please see Figures 1 to 6 An auxiliary temperature control device for an electromagnetic induction heating roller includes an electromagnetic coil 2 at the bottom of a mounting frame 1, the electromagnetic coil 2 being sleeved on the outside of the heating roller, an atomizing box 3 being fixedly connected to the top of the mounting frame 1, and conduits 4 being fixedly connected to both sides of the atomizing box 3. Spraying components are connected to the ends of the two conduits 4 away from the atomizing box 3, and the two spraying components are located on both sides of the electromagnetic coil 2. A flipping component is connected between the two spraying components, and a lifting component is connected to the side of the flipping component closer to the mounting frame 1. The lifting component is connected to the mounting frame 1.

[0024] like Figures 1 to 6 As shown, the main improvement of this utility model lies in improving the cooling efficiency of the electromagnetic heating roller, such as... Figures 1 to 6As shown, in the auxiliary temperature control device for the electromagnetic induction heating roller of this utility model, when the temperature sensor on the heating roller detects that the temperature is too high, the electromagnetic coil 2 stops heating. At the same time, the lifting assembly lowers the two spraying assemblies from the mounting frame 1 to a position close to the heating roller. Then, the flipping assembly flips the two spraying assemblies inward to surround the heating roller. Finally, the atomizing spray is introduced into the spraying assembly through the conduit 4 through the atomizing box 3 at the top of the mounting frame 1, and sprayed onto the surface of the heating roller through the spraying assembly. This uses cooling mist to quickly cool the surface of the heating roller, improving the cooling efficiency of the heating roller. At the same time, atomized cooling makes the cooling process of the heating roller more gentle, ensuring cooling efficiency while avoiding potential damage caused by rapid cooling of the heating roller. It should be noted that the conduit 4 needs to use a flexible hose to facilitate the lifting and lowering of the spraying assembly. At the same time, a pump is integrated in the atomizing box 3 to deliver the atomized gas to the spraying assembly. This is an existing structure and will not be described in detail.

[0025] like Figures 2 to 6 As shown, the lifting assembly includes two cylinders 5, which are respectively embedded at both ends of the bottom of the mounting frame 1. The telescopic ends of the two cylinders 5 are fixedly connected to the lifting plates 6, and the tilting assembly is connected to the two lifting plates 6. The bottom of the mounting frame 1 simultaneously lifts and lowers the two lifting plates 6 through the two cylinders 5, ensuring that the spraying assembly can move stably up and down.

[0026] like Figure 5 and Figure 6 As shown, a reinforcing rib 13 connects the two lifting plates 6. The two ends of the reinforcing rib 13 are fixedly connected to the middle position of adjacent sides of the two lifting plates 6, respectively. Two spraying components are located on both sides of the reinforcing rib 13. Installing the reinforcing rib 13 between the two lifting plates 6 prevents them from moving towards either end, ensuring the stability of the tilting components and spraying components installed on the lifting plates 6, and improving the structural strength between the two lifting plates 6.

[0027] like Figures 1 to 6 As shown, the tilting assembly includes two symmetrically arranged tilting rods 7. The two ends of each tilting rod 7 are rotatably connected to two lifting plates 6 via pivots. The sides of the two tilting rods 7 that are furthest from each other are connected to two spraying assemblies. A drive assembly is connected to the outer side of one of the lifting plates 6. The two tilting rods 7 are located on either side of the reinforcing rib 13. The spraying assembly can freely tilt between the two lifting plates 6 via the pivots at both ends of the tilting rods 7. Simultaneously, the drive assembly facilitates control of the tilting angle of the tilting rods 7, thereby driving the tilting angle of the spraying assembly.

[0028] like Figures 1 to 6As shown, the driving assembly includes a driving motor 8, a driving gear 9 and a driven gear 10, the rotating shafts of the two turning rods 7 at the same end are penetrated through the hoisting plates 6, and are fixedly connected with the driving gear 9 and the driven gear 10 respectively, the driving gear 9 is engaged with the driven gear 10, the output shaft of the driving motor 8 is fixedly connected with the driving gear 9, and the driving motor 8 is fixedly installed on the outside of the hoisting plate 6 through a motor base. The driving motor 8 drives the driving gear 9 to rotate, and the driven gear 10 engaged with the driving gear 9 synchronously drives the two turning rods 7 to realize relative turning between the two hoisting plates 6.

[0029] As shown in the figure, Figures 1 to 6 As shown, the spraying assembly includes a semicircular hollow plate 11 and a plurality of spray heads 12, the semicircular hollow plate 11 is fixedly connected with the turning rod 7, the plurality of spray heads 12 are uniformly distributed on the inner side of the recess of the semicircular hollow plate 11, and the plurality of spray heads 12 are fixedly connected with and communicated with the semicircular hollow plate 11, and the end of the conduit 4 away from the atomization box 3 is fixedly connected with and communicated with the outer side of the semicircular hollow plate 11. When it is detected that the temperature on the heating roller is too high, the two cylinders 5 synchronously drive the two hoisting plates 6 to be lowered from below the mounting frame 1, so that the two outwardly turned semicircular hollow plates 11 are lowered to the top of the heating roller and the electromagnetic coil 2, then the driving motor 8 is started, and the two turning rods 7 are synchronously driven to turn inwardly by the driving gear 9 and the driven gear 10, so as to drive the two outwardly turned semicircular hollow plates 11 to be folded inwardly at the same time, so as to enclose the heating roller and the electromagnetic coil 2 inwardly, at this time, the atomization box 3 simultaneously delivers the atomized cooling gas into the two semicircular hollow plates 11 through the conduits 4 on both sides, then the atomized cooling gas is sprayed from the plurality of spray heads 12 on the inner side of the semicircular hollow plate 11 to the heating roller, so that the atomized cooling gas contacts the surface of the heating roller, and the rapid cooling of the heating roller is realized, after the cooling operation is completed, the two semicircular hollow plates 11 can be conveniently folded upwardly, the electromagnetic coil 2 is heated again, and the observation of the heating roller is avoided.

[0030] As shown in the figure, Figures 3 to 6 As shown, the plurality of spray heads 12 are located between the coil slits of the electromagnetic coil 2. The plurality of spray heads 12 are arranged between the coil slits of the electromagnetic coil 2, when the spray heads 12 spray the atomized cooling gas, the atomized gas can be prevented from being sprayed onto the electromagnetic coil 2, so that the atomized gas better contacts the heating roller, and the atomization cooling effect is further improved.

[0031] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model.
