Technical Field
[0001] This utility model relates to the field of hollow panel manufacturing technology, specifically a hot air circulation mechanism for a hollow panel manufacturing oven. Background Technology
[0002] The production of hollow square panels mainly involves specialized production lines and equipment, and continuous production through specific processes. Hollow square panels, also known as hollow boards or corrugated boards, are a new type of material that is lightweight, non-toxic, non-polluting, waterproof, shockproof, anti-aging, corrosion-resistant, and available in a variety of colors. The production process mainly relies on specialized hollow square panel production lines, which are typically equipped with intelligent operation and processing systems, user-friendly structural designs, and stable production equipment to ensure the production of high-quality products. Drying is a crucial step in the production of hollow square panels.
[0003] However, the existing hot air circulation mechanism of the hot drying oven for hollow panel production still has some problems in use:
[0004] In the existing hot air circulation mechanism of the hot drying oven for hollow panel production, the simultaneous operation of multiple components inside the CNC machining center during the cutting process inevitably causes vibration to the CNC machining center, resulting in shaking and other issues. This not only affects the cutting accuracy but also the processing quality, reduces the efficiency of the CNC machining center, and makes it unable to meet processing requirements.
[0005] Therefore, we propose a hot air circulation mechanism for a hot drying oven used in the production of hollow cell boards to solve the problems mentioned above. Utility Model Content

This not only affects the cutting accuracy but also the processing quality, reduces the efficiency of the CNC machining center, and makes it unable to meet processing requirements.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a hot air circulation mechanism for a hollow cell panel production oven, comprising a housing and a controller:
[0008] A controller is fixedly installed on one side of the enclosure, a display is fixedly installed on the outer surface of the enclosure, a sealed door is rotatably connected to the outside of the enclosure, an air inlet fan is fixedly installed at the rear end of the enclosure, a diverter pipe is fixedly connected to the air outlet of the air inlet fan, a heating box is fixedly installed on the inner side wall of the enclosure, and two sets of heating boxes are symmetrically arranged along the inside of the enclosure, an air outlet is opened on the side end face of the heating box, a heater is installed inside the heating box, a heating wire is embedded inside the heater, and a temperature sensor is fixedly installed on the inner wall of the enclosure.
[0009] Using the above technical solution, the air intake fan delivers external air to the heating chamber of the box through the diversion pipe. The cold air is then heated by the heater and heating wire inside the heating chamber to form hot air. The heated hot air is then evenly discharged through the air outlet on the side of the heating chamber, thus achieving heat drying treatment of the inside of the box.
[0010] Preferably, the diversion pipe is divided into two branches, and the two branches of the diversion pipe are connected to the two sets of heating boxes in a corresponding flow connection.
[0011] By adopting the above technical solution, external air is delivered to the two sets of heating chambers inside the chamber through the diversion pipe, which can increase the heating area and improve the heating effect.
[0012] Preferably, several air outlets are evenly distributed along the outer surface of the heating box, and the heating wires are arranged in an S-shape along the inside of the heater.
[0013] Using the above technical solution, multiple air outlets are distributed along the outer surface of the heating box, which allows hot air to be evenly discharged into the box, thereby achieving uniform heating of the central air-filled plate. The heating wires are arranged in an S-shape inside the heater, which can increase the contact area between the heating wires and the air and improve the heating efficiency.
[0014] Preferably, a slide rail is fixedly installed at the bottom of the box, a shelf is provided inside the box, and a pulley is fixedly installed at the bottom of the shelf, with the pulley slidably connected to the slide rail.
[0015] Using the above technical solution, the placement rack inside the box is connected to the slide rail via pulleys, which makes it easy to place the hollow panel inside the box for heat drying.
[0016] Preferably, a fixing plate is fixedly installed at the end of the slide rail, a damper is fixedly installed on one side of the fixing plate, a spring is provided on the outer surface of the damper, and a baffle is fixedly installed at the other end of the damper and the spring.
[0017] By adopting the above technical solution, by installing a baffle with a spring and a damper at the end of the slide rail, it is possible to avoid collision between the placement rack and the box, thereby protecting the placement rack and the box and reducing noise and vibration.
[0018] Preferably, an exhaust fan is fixedly installed on the top of the housing, one end of the exhaust fan is fixedly connected to a connecting pipe, and the other end of the connecting pipe is in a flow connection with the interior of the housing.
[0019] With the above technical solution, an exhaust fan is installed on the top of the box. The exhaust fan is connected to the inside of the box through a connecting pipe, which can exhaust hot air and, together with the intake fan, realize the circulation of hot air, ensuring a more uniform temperature inside the box.
[0020] Compared with the prior art, the beneficial effects of this utility model are:
[0021] 1. Hot air is evenly distributed to two sets of heating chambers through an inlet fan and a distribution pipe, and then blown onto the central open space plate through evenly distributed air outlets on the side end face of the heating chamber. This achieves uniformity in the entire drying process, avoids local overheating or undercooling, and improves drying quality. The heaters inside the heating chambers are embedded with heating wires arranged in an S-shape, which increases the heating area, improves heating efficiency, and shortens drying time. Temperature sensors monitor the temperature inside the hot drying chambers in real time and feed it back to the controller, achieving precise temperature control and ensuring the high efficiency and stability of the drying process. The controller and display settings allow operators to easily control and monitor the working status of the hot drying chambers, improving production efficiency.
[0022] 2. The slide rails fixedly installed at the bottom of the chamber provide guidance and support for the movement of the rack, allowing it to move smoothly along the rails. The pulleys fixedly installed at the bottom of the rack are slidably connected to the slide rails. This design further ensures the smoothness and flexibility of the rack's movement, making it easy for operators to place or remove the openwork panels into the oven. The buffer device consisting of a fixed plate, damper, and spring fixedly installed at the end of the slide rail effectively slows down the speed of the rack when it moves to the end of the slide rail, avoiding violent impacts caused by inertia, protecting the chamber walls and rack from damage, and also reducing noise. The baffle fixedly installed at the other end of the damper and spring not only enhances the strength of the entire buffer device but also acts as a limit, ensuring that the rack is effectively blocked and positioned when it moves to the end of the slide rail, preventing it from continuing to move forward or wobbling, thus ensuring the stability of the rack and openwork panels during the oven drying process.

Figures 1-6 This utility model provides a technical solution: a hot air circulation mechanism for a hot drying oven for producing hollow cell boards, comprising a box body 1 and a controller 2: the controller 2 is fixedly installed on one side of the box body 1, a display 3 is fixedly installed on the outer surface of the box body 1, a sealing door 4 is rotatably connected to the outside of the box body 1, an air inlet fan 5 is fixedly installed at the rear end of the box body 1, a diverter pipe 6 is fixedly connected to the air outlet end of the air inlet fan 5, a heating box 7 is fixedly installed on the inner side wall of the box body 1, and two sets of heating boxes 7 are symmetrically arranged along the inside of the box body 1, an air outlet 8 is opened on the side end face of the heating box 7, a heater 9 is installed inside the heating box 7, a heating wire 10 is embedded inside the heater 9, and a temperature sensor 11 is fixedly installed on the inner wall of the box body 1; the diverter pipe 6 is divided into two branches, and the two branches of the diverter pipe 6 are correspondingly connected to the two sets of heating boxes 7; several air outlets 8 are evenly distributed along the outer surface of the heating box 7, and the heating wires 10 are arranged in an S-shape along the inside of the heater 9.
[0032] The chamber 1, as the main body of the entire hot air drying oven, provides a closed space for the drying process. A controller 2 is fixedly installed on one side of the chamber 1 to control and adjust the working status of the oven. A display 3 is also fixedly installed on the outer surface of the chamber 1, which can display the temperature and other relevant information inside the chamber 1 in real time, facilitating operator monitoring. A sealing door 4 is rotatably connected to the outside of the chamber 1 to maintain its airtightness during the drying process, preventing heat loss and the entry of external impurities. An air intake fan 5 is fixedly installed at the rear of the chamber 1, serving as the power source for hot air circulation. It draws in outside air and heats it. A diversion pipe 6 is fixedly connected to the outlet of the air intake fan 5. The diversion pipe 6 is divided into two branches, each corresponding to one of the two heating chambers 7, ensuring that the hot air is evenly distributed to the two heating chambers 7. High heating efficiency: Two sets of heating chambers 7 are symmetrically arranged inside the chamber 1, with air outlets 8 on their side end faces. Several air outlets 8 are evenly distributed along the outer surface of the heating chamber 7 to ensure that hot air can be blown evenly onto the central open space plate, improving drying uniformity. Heaters 9 are installed inside the heating chamber 7, with heating wires 10 embedded inside. The heating wires 10 are arranged in an S-shape along the inside of the heater 9, which increases the heating area and improves heating efficiency. Temperature sensors 11 are also fixedly installed on the inner wall of the chamber 1 to monitor the temperature inside the hot drying chamber in real time and transmit the signal to the controller 2. The controller 2 can automatically adjust the power of the heater 9 and the speed of the air inlet fan 5 according to the feedback from the temperature sensor 11 to keep the temperature inside the hot drying chamber within the set range, ensuring the high efficiency and stability of the drying process.
[0033] A slide rail 12 is fixedly installed at the bottom of the box 1. A placement rack 13 is provided inside the box 1. A pulley 14 is fixedly installed at the bottom of the placement rack 13, and the pulley 14 is slidably connected to the slide rail 12. A fixing plate 15 is fixedly installed at the end of the slide rail 12. A damper 16 is fixedly installed on one side of the fixing plate 15. A spring 17 is provided on the outer surface of the damper 16. A baffle 18 is fixedly installed at the other end of the damper 16 and the spring 17.
[0034] A slide rail 12 is fixedly installed at the bottom of the inner chamber 1, providing guidance and support for the movement of the placement rack 13. The placement rack 13 is used to carry the hollow panel. A pulley 14 is fixedly installed at its bottom. The pulley 14 is slidably connected to the slide rail 12, allowing the placement rack 13 to move easily along the slide rail 12, making it convenient for operators to put the hollow panel into or take out of the hot oven. At the end of the slide rail 12, a fixing plate 15 is fixedly installed. A damper 16 is fixedly installed on one side of the fixing plate 15. A spring 17 is provided on its outer surface to slow down the speed of the placement rack 13 when it moves to the end of the slide rail 12, preventing it from violently hitting the wall of the chamber 1 due to inertia, causing damage or noise. A baffle 18 is fixedly installed at the other end of the damper 16 and the spring 17. The baffle 18 not only enhances the strength of the entire buffer device, but also plays a limiting role, ensuring that the placement rack 13 can be effectively blocked and positioned when it moves to the end of the slide rail 12, preventing it from continuing to move forward or shake.
[0035] An exhaust fan 19 is fixedly installed on the top of the housing 1. One end of the exhaust fan 19 is fixedly connected to a connecting pipe 20, and the other end of the connecting pipe 20 is in a flow connection with the interior of the housing 1.
[0036] An exhaust fan 19 is fixedly installed above the housing 1, allowing hot air to be drawn out of the housing 1 under the drive of the fan. One end of the exhaust fan 19 is fixedly connected to a connecting pipe 20, which serves as a channel for hot air circulation. The other end of the connecting pipe is in a circulating connection with the interior of the housing 1. Thus, when the exhaust fan 19 is started, hot air is drawn out of the housing 1 and passes through the connecting pipe 20. Depending on the specific design requirements, the hot air may be reheated or directed to other parts of the housing 1 to achieve hot air circulation. Through the circulation of hot air, the temperature inside the housing 1 can be made more uniform, thereby accelerating the drying speed of the hollow glass panels and ensuring drying uniformity. Hot air circulation can ensure that every corner inside the housing 1 is fully heated, avoiding local overheating or undercooling and ensuring uniform drying quality.
[0037] Working Principle: For the hot air circulation mechanism of the hot drying oven in the production of this type of hollow panel, during the drying process, outside air is drawn into the oven body 1 by the inlet fan 5, and then evenly distributed to the two sets of heating chambers 7 through the diversion pipe 6. Each heating chamber 7 is equipped with a heater 9, which has S-shaped heating wires 10 embedded inside to heat the air. This increases the heating area and improves heating efficiency. The heated air is blown into the oven body 1 through evenly distributed air outlets 8 on the side end face of the heating chamber 7. Simultaneously, a temperature sensor 11 is fixedly installed on the inner wall of the oven body 1 to monitor the temperature inside the oven in real time. The temperature sensor 11 transmits the signal to the controller 2, and the controller 2 automatically adjusts the heating based on the feedback from the temperature sensor 11. The power of the air conditioner 9 and the rotation speed of the air intake fan 5 are adjusted to maintain the temperature inside the chamber 1 within the set range, ensuring the efficiency and stability of the drying process. In addition, a slide rail 12 is fixedly installed at the bottom of the chamber 1, providing guidance and support for the movement of the placement rack 13. The placement rack 13 is used to carry the hollow panel, and a pulley 14 is fixedly installed at its bottom, allowing the placement rack 13 to move easily along the slide rail 12, making it convenient for operators to put the hollow panel into or take out of the hot drying oven. At the end of the slide rail 12, a buffer device consisting of a fixing plate 15, a damper 16, and a spring 17, as well as a baffle 18, are fixedly installed. These components work together to slow down the speed of the placement rack 13 when it moves to the end of the slide rail 12, preventing it from violently impacting the wall of the chamber 1 due to inertia, causing damage or noise. Meanwhile, the baffle 18 also serves as a limit, ensuring that the placement rack 13 can be effectively blocked and positioned when it moves to the end of the slide rail 12. Finally, an exhaust fan 19 is fixedly installed above the box 1. When the exhaust fan 19 is started, hot air will be drawn out from the box 1 through the connecting pipe 20. Through the circulation of hot air, the temperature inside the box 1 can be made more uniform, thereby accelerating the drying speed of the hollow panel and ensuring the uniformity of the drying quality.
