[0013] The present utility model will be specifically described below in conjunction with the drawings:

[0014] As shown in FIGS. 1 and 2, the degradable fiber low-carbon full-automatic pulp molding production line of the present utility model includes a pulp molding drying box 1. Openings are respectively provided on the left and right sides inside the pulp molding drying box 1, and a mesh chain conveyor 2 is fixedly connected inside between the openings; an observation window 3 is fixedly connected in sequence from left to right at the upper middle opening of the front part of the pulp molding drying box 1; support frames 4 are respectively fixedly connected on the left and right sides of the upper part inside the pulp molding drying box 1.

[0015] Among them, the degradable fiber low-carbon full-automatic pulp molding production line further includes an airless heating and drying assembly 5, and the airless heating and drying assembly 5 is fixedly connected between the lower parts of the support frames 4, which is conducive to achieving the effect of drying pulp molding without wind, effectively avoiding the problem of local deformation of pulp molding during the drying process, and thus effectively improving the processing quality of pulp molding; the working process of the present utility model has no aerobic combustion, so that low-carbon environmental protection work can be achieved.

[0016] In this embodiment, in combination with the attachedFigure 3 As shown, the airless air-heated drying assembly 5 includes a hollow drying plate 51, and a heat conducting plate 52 is integrally connected to the inside of the hollow drying plate 51 in sequence from left to right; at the opening in the middle of the rear part of the hollow drying plate 51, an air inlet pipe 53 is fixedly connected, and an air inlet valve 54 is fixedly connected to the rear end of the air inlet pipe 53; at the opening in the middle left side of the air inlet pipe 53, a temperature regulating pipe 55 is integrally connected, and the left end of the temperature regulating pipe 55 is inclined backward. One end of the temperature regulating pipe 55 away from the air inlet pipe 53 is fixedly connected with a temperature regulating valve 56; a separate air compressor 57 is arranged at the rear side of the air inlet valve 54, and the output end of the air compressor 57 is connected to the rear end of the air inlet valve 54 through a pipeline; exhaust pipes 58 are fixedly connected to the openings on the left and right sides of the rear part of the hollow drying plate 51 respectively, and exhaust valves 59 are fixedly connected to the rear ends of the exhaust pipes 58 respectively.

[0017] In this embodiment, specifically, the left and right sides of the middle part of the upper part of the hollow drying plate 51 are fixedly connected to the lower part of the support frame 4 respectively.

[0018] In this embodiment, specifically, the air inlet pipe 53 penetrates through the rear side inside the pulp molding drying box 1, and the temperature regulating pipe 55 is arranged at the rear side of the pulp molding drying box 1.

[0019] In this embodiment, specifically, the exhaust pipes 58 penetrate through the rear side inside the pulp molding drying box 1 respectively.

[0020] In this embodiment, specifically, the hollow drying plate 51 is made of a hollow aluminum alloy plate.

[0021] In this embodiment, specifically, the heat conducting plate 52 is made of an aluminum alloy mesh plate with a rectangular longitudinal section. The thickness of the heat conducting plate 52 decreases sequentially from the middle to both sides. Since the heat conducting plate 52 in the middle is thicker and the heat conducting plates 52 on both sides are thinner, the heat conducting plate 52 in the middle can absorb a large amount of heat in the air, and the heat conducting plates 52 on both sides can absorb less heat in the air. At this time, the temperature in the middle part of the hollow drying plate 51 is higher, while the temperature on both sides of the hollow drying plate 51 is relatively lower, thus avoiding the problem that the pulp molding directly cracks due to high temperature.

[0022] In this embodiment, specifically, the rear ends of the exhaust valves 59 are respectively connected to the input ends of an external cooler through pipelines.

[0023] In this embodiment, specifically, the temperature regulating pipe 55 is made of a stainless steel pipe.

[0024] In this embodiment, specifically, the observation window 3 is made of a transparent tempered glass window.

[0025] In this embodiment, specifically, the intake valve 54, the temperature regulating valve 56, and the exhaust valve 59 are respectively solenoid valves.

[0026] In this embodiment, specifically, the intake valve 54, the temperature regulating valve 56, the air compressor 57, the exhaust valve 59, and the mesh belt conveyor 2 are respectively electrically connected to an external control panel.

[0027] In this embodiment, when drying the pulp molding, the operator can operate the external control panel to enter the drying mode. At this time, the control panel will automatically control the air compressor 57 to start, and at the same time control the intake valve 54 and the exhaust valve 59 to open. Subsequently, the air compressor 57 will send high-temperature gas through the pipeline, the intake valve 54, and the intake pipe 53 into the hollow drying plate 51. The hollow drying plate 51 will absorb the heat in the air. At the same time, the heat conducting plate 52 will increase the contact area and time between the hollow drying plate 51 and the high-temperature gas, thereby effectively improving the heat utilization rate. Finally, the high-temperature gas will be discharged into an external cooler through the exhaust pipe 58 and the exhaust valve 59 for cooling and emission. Since the hollow drying plate 51 releases heat to the pulp molding drying box 1 after absorbing heat, the pulp molding can be dried without wind through the hollow drying plate 51, thereby effectively avoiding the problem of local deformation of the pulp molding and achieving the effect of drying the pulp molding without wind, and effectively improving the processing quality of the pulp molding. When it is necessary to adjust the temperature in the hollow drying plate 51, the operator can control the temperature regulating valve 56 to open partially through the external control panel, so that external air can enter the intake pipe 53 through the temperature regulating pipe 55, thereby reducing the temperature of the air in the intake pipe 53 and achieving the purpose of adjusting the temperature.

[0028] Any technical solution using the technical solution of the present invention, or a technical solution designed by those skilled in the art inspired by the technical solution of the present invention and achieving the above technical effects shall fall within the protection scope of the present invention.
