[0035] The working process of the heavy-duty closed-loop stepping integrated oven of the utility model is:

[0036] When automatically started in the no-material state, the lifting and conveying platform 41 at the entrance of the pre-bake heating section 1 descends, the lifting and conveying platform 41 at the connection between the exit of the pre-bake heating section 1 and the entrance of the gluing section 2 rises, the lifting and conveying platform 41 at the connection between the exit of the gluing section 2 and the entrance of the solid baking heating section 3 descends, and the lifting and conveying platform 41 at the exit of the solid baking heating section 3 rises.

[0037] When there is material to start automatically, the process is as follows:

[0038] 1. When the material frame 9 with the material placed therein moves to the entrance of the pre-baking and heating section 1 driven by the first conveying chain 6, after the arrival detection device detects that the material frame 9 is in place, the lifting and conveying platform 41 starts to rise, and after rising to the position, it waits to be conveyed to the baking box 32 of the pre-baking and heating section 1; after the baking time of the pre-baking and heating section 1 is reached, the automatic insulation door 33 is opened, and the material frame 9 is conveyed into the baking box 32 by the second conveyor belt 42 on the lifting and conveying platform 41. After being conveyed to the position, the automatic insulation door 33 is closed, and the next step of step timing preparation is entered;

[0039] 2. After the material on the material frame 9 is baked in the baking box 32 of the pre-baking and heating section 1, the automatic insulation door 33 at the outlet of the pre-baking and heating section 1 is opened and closed after the material frame 9 is output. At this time, the lifting and conveying platform 41 at the junction of the outlet of the pre-baking and heating section 1 and the entrance of the gluing section 2 rises to receive the material until the second conveyor belt 42 conveys the material frame 9 to the right place and then stops. After the delay time, the lifting and conveying platform 41 descends until the material frame 9 is placed on the second conveying chain 7;

[0040] 3. The second conveying chain 7 drives the material frame 9 to be conveyed along the gluing section 2. When the material frame 9 is in place, the material on the material frame 9 is coated with glue. After the gluing is completed, the material frame 9 is then conveyed to the exit of the gluing section 2 and the entrance of the curing and heating section 3;

[0041] 4. When the in-place detection device detects that the material frame 9 is in place, the lifting conveyor 41 starts to rise, and after rising to the position, it waits to feed the material to the fixed baking heating section 3. After the baking time is reached, the automatic insulation door 33 opens, and the material frame 9 is conveyed to the baking box 32 through the second conveyor belt 42. After being conveyed to the position, the automatic insulation door 33 is closed;

[0042] 5. After the material is baked in the baking box 32 of the solid baking and heating section 3, the automatic insulation door 33 at the outlet of the solid baking and heating section 3 is opened and closed after the material frame 9 is output. At this time, the lifting conveying platform 41 at the outlet of the solid baking and heating section 3 rises to receive the material frame 9 until the second conveyor belt 42 conveys the material frame 9 to the right place and then stops. After the delay time, the lifting conveying platform 41 descends until the material frame 9 is placed on the first conveying chain 6;

[0043] 6. The first conveyor chain 6 continues to convey the material frame 9 forward. When the photoelectric sensor 81 senses the presence of material, the discharge position blocking cylinder 82 rises. After the material frame 9 is in place, the first conveyor chain 6 stops conveying. Then the discharge position positioning cylinder 83 drives the clamping claw 84 to fix and limit the material frame 9, waiting for personnel to pick up and change materials. After the material picking and changing is completed, the above action process is repeated again.
