Description

Technical Field

[0001] This utility model relates to the field of heating device technology, specifically to an induction heating device with intelligent temperature adjustment. Background Technology

[0002] Thin-sheet stainless steel is a widely used material in sheet metal manufacturing. Its processing principle involves the raw material undergoing plastic deformation under external force within the equipment to obtain parts of the desired shape and size. The surface protection measures for thin-sheet stainless steel vary depending on the processing requirements. Laser cutting is the most common cutting process for thin-sheet stainless steel sheet metal parts. To prevent scratches on the material surface during cutting and subsequent processing, a special protective film for laser cutting is usually applied to the surface of the sheet metal parts. However, this protective film has strong adhesiveness and adsorption, requiring removal after processing. At room temperature, removing this protective film is difficult and can easily damage the workpiece surface due to improper removal. Multiple experiments have verified that when the ambient temperature or workpiece surface temperature is controlled within the range of 30℃ to 40℃, the adhesiveness of the protective film significantly decreases, making it easiest to remove. Utility Model Content

[0003] The purpose of this invention is to provide an intelligent temperature-adjustable induction heating device to solve the problem of the difficulty in removing the special protective film at room temperature.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: An intelligent temperature-adjustable induction heating device includes: a mounting frame, several electric heating modules, a temperature sensor, a heat-conducting plate, and a distribution box. The device has a grid-type structure, with the heating surface of each electric heating module close to the grid-type structure. The heat-conducting plate is located below the bottom of the mounting frame, close to the grid-type structure. The temperature sensor is located on the body of each electric heating module and is signal-connected to it. The distribution box is located on the side wall of the mounting frame and is electrically connected to the electric heating modules and the temperature sensor.

[0005] As a preferred technical solution, several of the electric heating modules are arranged in two rows within the mounting frame.

[0006] As a preferred technical solution, the bottom upper surface of the mounting frame is provided with limiting members on both sides of each column of electric heating modules.

[0007] As a preferred technical solution, the limiting member is an L-shaped plate, one side of which is fixedly connected to the bottom of the mounting frame, and the other side abuts against the side of the electric heating module.

[0008] As a preferred technical solution, the mounting frame is provided with a bracket at its bottom.

[0009] As a preferred technical solution, the top of the mounting frame is provided with a cover plate.

[0010] As a preferred technical solution, the heat-conducting plate has an inverted V-shaped cross-section.

[0011] As a preferred technical solution, the heating surface of the electric heating module has a serpentine mounting cavity.

[0012] As a preferred technical solution, a control switch is provided on the side wall of the mounting frame for each of the electric heating modules, and the control switch is electrically connected to the electric heating module and the temperature sensor.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: This invention can heat workpieces that require removal of surface coatings, thereby reducing the stickiness and adsorption of the protective film on the workpiece surface, facilitating subsequent removal of the protective film; the optimized heating device can effectively transfer the generated heat to the designed location, improving heating efficiency; the temperature sensor can monitor the temperature in real time, respond promptly and take measures, effectively reducing production costs and preventing potential safety risks.

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0017] Example 1 like Figure 1-4 As shown, this embodiment discloses an intelligent temperature-adjustable induction heating device, including: a mounting frame 1, several electric heating modules 2, a temperature sensor 3, a heat-conducting plate 4, and a distribution box 5. The several electric heating modules 2 are horizontally laid on the bottom upper surface of the mounting frame 1. The bottom of the mounting frame 1 has a grid structure. The heating surface of the electric heating modules 2 is close to the grid structure. The heat-conducting plate 4 is disposed below the bottom of the mounting frame 1 close to the grid structure. The temperature sensor 3 is disposed on the body of the electric heating module 2 and is signal-connected to the electric heating module 2. The distribution box 5 is disposed on the side wall of the mounting frame 1 and is electrically connected to the electric heating modules 2 and the temperature sensor 3.

[0018] It should be noted that the mounting frame 1 in this embodiment has a rectangular structure. The mounting frame 1 is placed on a workbench, on which a thin stainless steel sheet is placed at the bottom. The bottom of the mounting frame 1 has a grid-like structure. This structure provides stable support for the electric heating module 2 and ensures that heat penetrates evenly through the bottom of the mounting frame 1 to heat the sheet metal sheet below, avoiding localized heat accumulation. The electric heating modules 2 are evenly distributed on top of the grid-like structure, ensuring as much coverage as possible and eliminating any dead corners in the heating area. A heat-conducting plate 4 is positioned below the bottom of the mounting frame 1, near the grid structure, to conduct heat generated by the electric heating module 2 to the thin stainless steel plate below. Each electric heating module 2 has a corresponding temperature sensor 3 that collects its output temperature data in real time and controls the module's operation based on the detected temperature data. When the temperature of the electric heating module 2 exceeds a preset upper limit, the temperature sensor 3 controls it to stop heating to ensure safety. After stopping, if the temperature drops below the set value, the temperature sensor 3 restarts the heating module 2, thus regulating the operating temperature. A commercially available distribution box 5 can be used, electrically connected to both the electric heating module 2 and the temperature sensor 3 via cables to supply power.

[0019] Example 2 like Figure 1-4 As shown, this embodiment is based on the above embodiment. Specifically, several electric heating modules 2 are arranged in two columns within the mounting frame 1. In this embodiment, the electric heating modules 2 are preferably arranged in two columns and three rows, totaling six electric heating modules 2, to meet the heating requirements of covering the long strip of sheet metal.

[0020] Furthermore, limiting members 6 are provided on both sides of the bottom upper surface of the mounting frame 1 corresponding to each row of electric heating modules 2. The limiting members 6 can prevent the electric heating modules 2 from shifting, thereby ensuring the stability of the heating area.

[0021] Furthermore, the limiting member 6 is an L-shaped plate, one side of which is fixedly connected to the bottom of the mounting frame 1, and the other side abuts against the side of the electric heating module 2. This type of limiting member 6 ensures structural strength without excessively occupying installation space. Preferably, the L-shaped plate is connected to the bottom of the mounting frame 1 by bolts.

[0022] Example 3 like Figure 1-4 As shown, this embodiment is based on the above embodiment. Specifically, a bracket 7 is provided at the bottom of the mounting frame 1. The bracket 7 provides mounting support for the mounting frame 1.

[0023] Example 4 like Figure 1-4 As shown, this embodiment is based on the above embodiment. Specifically, a cover plate 8 is provided on the top of the mounting frame 1 to provide protection for the interior of the mounting frame.

[0024] Example 5 like Figure 1-4 As shown, this embodiment is based on the above embodiment. Specifically, the heat-conducting plate 4 has an inverted V-shaped cross section, so that heat is transferred from both sides of the heat-conducting plate 4 to the bottom.

[0025] Example 6 like Figure 1-4 As shown, this embodiment is based on the above embodiment. Specifically, the heating surface of the electric heating module 2 has a serpentine mounting cavity. The serpentine mounting cavity 9 is used to install the heating tube.

[0026] Example 7 like Figure 1-4 As shown, this embodiment is based on the above embodiment. Specifically, a control switch 10 is provided on the side wall of the mounting frame 1 for each of the electric heating modules 2. The control switch 10 is electrically connected to the electric heating module 2 and the temperature sensor 3. The control switch 10 controls the opening and closing of the electric heating module 2.
