[0030] The following is combined with Figure 1-12 This application is described in further detail.

[0031] Reference Figure 1 and Figure 2 The embodiment of the present application discloses a high-temperature heating device for preventing oxidation of a sheet, comprising an automatic feeding component 1, a heating chamber 2 and a protective gas supply component 3. The heating chamber 2 is used to heat a sheet 100, and at least one end is provided with an inlet and outlet 21. The automatic feeding component 1 is used to feed the sheet 100 into the heating chamber 2 from the inlet and outlet 21, and take it out of the heating chamber 2 after heating is completed. The protective gas supply component 3 is used to blow protective gas into the heating chamber 2 to form a protective atmosphere to prevent the sheet 100 from being oxidized during high-temperature heating.

[0032] The protective gas can be selected according to actual needs, and generally an inert gas is used. In order to reduce the amount of protective gas used, the accommodating space in the heating chamber 2 is preferably a slit-type structure, slightly larger than the thickness of the sheet 100, so as to facilitate the entry and exit of the sheet 100.

[0033] Reference Figures 3 to 6 The heating chamber 2 includes a heat-conducting sheet bottom plate 22, a sealing cover plate 23, a sealing strip 24, a heating element 25 and a heating element fixing plate 26. The bottom surface of the heat-conducting sheet bottom plate 22 is provided with a groove 221 for accommodating the heating element 25. The heating element fixing plate 26 is used to cover and fix the heating element 25. The sealing strip 24 is arranged between the heat-conducting sheet bottom plate 22 and the sealing cover plate 23 to enhance the sealing performance of the side. The heat-conducting sheet bottom plate 22 and / or the sealing cover plate 23 are also provided with an air inlet 27, and the air inlet 27 is connected to the protective gas supply assembly 3.

One or more rows of blowing holes 281 are provided on the blowing rod 28, so that the protective gas can better fill the heating chamber 2 and exhaust the air.

[0035] Reference Figure 7 The sheet material anti-oxidation high temperature heating device also includes a sheet material limiting assembly 4, which is used to limit the left and right feeding positions of the sheet material 100. The sheet material limiting assembly 4 includes a fixed block 41, an adjusting block 42, a fixed rod 43, a threaded adjusting rod 44 and a hand wheel 45. The fixed rod 43 is fixed on the fixed block 41, and the adjusting block 42 is slidably arranged on the fixed rod 43. The threaded adjusting rod 44 is threadedly connected with the adjusting block 42. The hand wheel 45 is arranged at one end of the threaded adjusting rod 44. The adjusting block 42 is driven to approach or move away from the fixed block 41 by rotating the hand wheel 45 and the threaded adjusting rod 44. Each time the product is changed, it is necessary to adjust the spacing between the fixed block 41 and the adjusting block 42 to adapt to the width of different sheets 100, to ensure that the sheet material 100 can accurately enter the heating chamber 2 without deflection, to avoid the jamming of the automatic feeding assembly 1 and to affect the normal transportation of the sheet material 100.

[0036] Reference Figure 8 The automatic feeding assembly 1 includes a first support plate 11, a second support plate 12, a motor 13, a feeding roller 14, a sheeting rubber wheel 15 and a sheeting cylinder 16. The feeding roller 14 is rotatably arranged between the first support plate 11 and the second support plate 12. The motor 13 is arranged on the first support plate 11 and connected to the feeding roller 14 through a coupling 17 to drive the feeding roller 14 to rotate. The sheeting rubber wheel 15 is arranged on the cylinder shaft of the sheeting cylinder 16. The sheeting cylinder 16 is arranged on the second support plate 12 to drive the sheeting rubber wheel 15 to rise and fall, so as to press the sheet 100 between the feeding roller 14 and the sheeting rubber wheel 15. The automatic feeding method is adopted to reduce the risk of scalding of the staff due to the high temperature of the equipment.

[0037] Reference Fig.10 and Fig.11The protective gas supply assembly 3 includes a placement rack 31, a combination box 32, a flow meter 33, a regulating valve 34 and a manifold block 35. The combination box 32 is arranged on the placement rack 31, the flow meter 33 is arranged in the combination box 32 through a fixing plate 36, the manifold block 35 is arranged on the inner wall of the combination box 32, and the regulating valve 34 is arranged on the outer wall of the combination box 32. The external gas source is connected to the manifold block 35, the regulating valve 34 and the flow meter 33 in sequence, and finally connected to the heating chamber 2. In this embodiment, there are two manifold blocks 35, each of which is provided with four manifold holes, and the corresponding number of flow meters 33 and regulating valves 34 is eight.

[0038] Reference Figure 1 , Figure 2 and Fig. 9 The sheet material anti-oxidation high temperature heating device further comprises a rack 5 and a workbench 6. The rack 5, the automatic feeding assembly 1 and the protective gas supply assembly 3 are all arranged on the workbench 6. The heating chamber 2 and the sheet material limiting assembly 4 are all arranged on the rack 5. Of course, the sheet material limiting assembly 4 can also be arranged on the heat-conducting sheet placing bottom plate 22. The rack 5 is welded by the bottom plate and the square tube. The bottom plate has a square hole 51 adapted to the heating element fixing plate 26, which is convenient for heat dissipation and reduces the adverse effect of the high temperature of the heating chamber 2 on the workbench 6.

[0039] Reference Figure 1 and Fig.12 The sheet material anti-oxidation high temperature heating device also includes a heat shield 7, which is arranged on the workbench 6 and is used to isolate the heating chamber 2. Because the heating chamber 2 can reach a high temperature of 500°C during operation, the heat shield 7 is added to prevent workers from accidentally touching and getting burned during operation.

[0040] The working process of the present application is as follows: turn on the heating element 25, and the heating chamber 2 gradually heats up; open the regulating valve 34, observe the flow meter 33, and adjust the regulating valve 34 to the required flow rate, so that the protective gas enters the heating chamber 2 and fills the gap between the heat-conducting sheet-setting bottom plate 22 and the sealing cover plate 23; when the temperature sensor detects that the temperature inside the heating chamber 2 reaches the requirement, the sheet 100 is placed in the limiting area of ​​the sheet limiting assembly 4, and the pressing cylinder 16 is started. The pressing cylinder 16 drives the pressing rubber wheel 15 to descend, and the sheet 100 is pressed between the pressing rubber wheel 15 and the feeding roller 14; the motor 13 is started, and the motor 13 drives the feeding roller 14 to rotate, and the feeding roller 14 feeds the sheet 100 into the heating chamber 2, and the motor 13 stops rotating after reaching the position; after the set baking time, the automatic feeding assembly 1 sends the sheet 100 out, and cools it after taking it out. After cooling, the surface of the sheet 100 can be observed and detected.

[0041] The present application heats the sheet 100 to a high temperature in the heating chamber 2. In order to prevent oxidation of the surface of the sheet 100, a protective gas is provided to the heating chamber 2 during the entire heating process to form a protective atmosphere to prevent the sheet 100 from being heated and oxidized at a high temperature, thereby reducing the impact on the judgment result and not easily causing misjudgment. In addition, due to the presence of the protective atmosphere, the heating temperature can also be appropriately increased, which can reduce a certain heating time, and the surface oxidation of the sheet 100 will not be significantly aggravated, which can improve the detection efficiency to a certain extent. For example, in the prior art, under the high temperature condition of 460°C, it is necessary to bake the sheet for five minutes. The present application raises the temperature to 500°C, and it only takes one minute to bake the sheet to achieve a similar baking and heating pretreatment effect.

[0042] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
