Detailed Implementation

[0030] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Example 1

[0031] Reference Figure 1 and Figure 2 This utility model provides a corrugated paper heating device, including a device body, with multiple ventilation grilles at the bottom of the device body, and a control panel on one side of the device body. The device body is characterized by a movable switch door 111 at the front, and the device body also includes a suspended heating module, which includes:

[0032] Mounting bracket 110 is fixedly installed inside heating chamber 100;

[0033] Placement plate 112 is fixedly installed on both sides inside the heating chamber 100;

[0034] There are four lower fans 113, and all of them are fixedly installed on the mounting bracket 110.

[0035] There are four jet nozzles 114. All jet nozzles 114 are connected to the lower fan 113. All jet nozzles 114 are fixedly installed on the mounting bracket 110.

[0036] Infrared heating lamp 115 is fixedly installed at the geometric center of the top surface of mounting bracket 110.

[0037] An upper fan 116 is fixedly installed at the top of the heating chamber 100. The bottom end of the upper fan 116 extends into the interior of the mounting bracket 110, and an air intake 117 is connected to the bottom end of the upper fan 116.

[0038] Working Principle: In this embodiment, airflow is injected upwards by the lower fan 113 and the jet nozzle 114, causing the corrugated cardboard above the placement plate 112 to suspend inside the heating chamber 100. This prevents the cardboard from shifting or vibrating due to uneven airflow, thus ensuring uniform heating. The infrared heating lamp 115 is a mid-wave infrared heating lamp, model Heraeus-IR-2450, fixedly installed at the geometric center of the top surface of the mounting frame 110. It radiates infrared heat energy upwards to perform non-contact heating on the suspended corrugated cardboard, improving heating efficiency and preventing uneven heating of the cardboard. An upper fan 116 is fixedly installed at the top of the heating chamber 100. It is an adjustable-speed axial flow fan, model Delta AFB Fresnel lens 1224SHE, with its bottom end extending into the interior of the mounting frame 110 and connected to the air intake 117. When the upper fan 116 is running, it can adsorb the top surface of the cardboard onto the air intake 117, enhancing the stability of the cardboard and preventing it from drifting due to airflow disturbance. The bottom of the main body of the device has multiple ventilation grilles to exhaust excess airflow, maintain internal air circulation, and improve suspension stability. A control panel is located on one side of the main body, using a Siemens TP700 Comfort PLC intelligent touchscreen. This panel can monitor and adjust the operating status of the lower fan 113, upper fan 116, and infrared heating lamp 115 in real time, achieving precise temperature control and airflow management. This optimizes the heating effect on the corrugated cardboard, improving product quality and production efficiency. Example 2

Simultaneously, two telescopic rods 119 are fixedly installed at the top of the interior of the heating chamber 100, and the bottom of the telescopic rods 119 are fixedly connected to the air intake 117. A pneumatic telescopic rod controls the height of the air intake 117, allowing it to adjust with the extension and retraction of the telescopic rods 119, thereby changing the suspension height of the cardboard. This ensures that corrugated paper of different thicknesses can receive infrared heating from the infrared heating lamp 115 within the optimal distance. The telescopic rod 119 model is SMC CJ2B16-Heating Chamber 100 Pneumatic Telescopic Rod. Two limiting frames 120 are fixedly installed at the top of the placement plate 112. These are stainless steel limiting frames made of AISI 304 material, ensuring that the suspended cardboard will not shift horizontally due to airflow disturbances, improving stability and heating uniformity. A reflector 121 is fixedly mounted on the outer surface of the infrared heating lamp 115. The reflector 121 is shaped like an inverted frustum and is made of high-reflectivity aluminum alloy, specifically 6061-T6 aluminum alloy, with a silver-plated surface. A Fresnel lens 122 is fixedly mounted on the top of the reflector 121. The Fresnel lens 122 is an Edmund Optics 83-920 IR lens, used to diffuse infrared light, ensuring uniform coverage of the entire corrugated cardboard surface and preventing localized overheating or energy concentration. Multiple diffuse reflection plates with alumina ceramic coating are fixedly mounted on the inner wall of the heating chamber 100 to optimize infrared light distribution, ensuring uniform scattering of heat energy across the entire heating area, improving the heating consistency of the corrugated cardboard, reducing light energy loss, and further improving heating efficiency and cardboard quality.
