Several positioning rods 8 are installed at the bottom of the inner cavities of the drying box 1 and the bundling tube 5. Rotary rollers 9 are sleeved on the surface of the positioning rods 8.

[0026] Reference Figure 1 , Figure 2 , Figure 3 Through the structural design of the bundle tube 5, positioning shaft 6, and sealing plate 7, the functions of saving energy and improving thermal efficiency are realized. This reduces the heat loss during feeding or discharging, thereby reducing the energy required for the heating rod and reducing the interference of the external environment on the interior of the drying oven 1.

[0027] A drive gear 10 is fixedly installed at the end of the output of the conveyor motor 3. A chain 11 is meshed with the surface of the drive gear 10. A conveyor roller 12 is rotatably installed on one side of the top of the inner cavity of the bundle tube 5.

[0028] Reference Figure 1 , Figure 2 , Figure 3 Through the structural design of drive gear 10, chain 11, conveyor roller 12, and transmission gear 13, it is easy to cooperate with conveyor motor 3 and drive roller 4 to realize the function of automated continuous feeding. This can form a continuous conveying system, thereby ensuring that the foam board flows continuously in the device, thus ensuring the continuity of drying, reducing the idle time of the device, improving production efficiency, and solving the problem of low production efficiency.

[0029] A control panel 14 is fixedly installed on one side of the drying oven 1. A temperature and humidity sensor is installed on the back of the control panel 14. Fan units 15 are threadedly connected to both sides of the top of the drying oven 1. A baffle 16 is movably installed on one side of the fan unit 15 and at the bottom of the fan.

[0030] Reference Figure 1 and Figure 4The control panel 14 facilitates the adjustment of the working status of the motor and heating rod, and can also be used with temperature and humidity sensors to monitor the internal environment of the drying chamber 1 to ensure the accuracy of the drying environment. The fan unit 15 facilitates the increase of air flow speed, thereby achieving the purpose of air intake and exhaust, so as to optimize the internal environment of the drying chamber 1 in the future. The baffle 16 facilitates the closure of the opening of the fan unit 15, thereby further improving the sealing performance of the device and further reducing the interference of the external environment on the interior of the drying chamber 1 and the energy consumption required by the heating rod.

[0031] A servo motor 17 is fixedly installed on the other side of the drying oven 1, and a few baffles 18 are fixedly installed on the surface of the output end of the servo motor 17.

[0032] Reference Figure 2 and Figure 3 The servo motor 17 and the baffle 18 facilitate the disturbance of the gas inside the drying chamber 1, so as to ensure that the foam board is dried evenly.

[0033] A return pipe 19 is fixedly installed in the middle part of both sides of the drying oven 1. A diffuser hood 20 is fixedly installed at the end of the return pipe 19. The top of the diffuser hood 20 is fixedly connected to the ground of the drying oven 1. Several second heating rods 21 are fixedly installed inside the return pipe 19.

[0034] Reference Figure 2 and Figure 5 The return pipe 19 and the diffuser 20 facilitate the recycling of the gas in the drying chamber 1, thereby further reducing the energy consumption of the heating rod. The second heating rod 21 facilitates the secondary heating of the gas during the return process, ensuring that the gas after return is at the correct temperature, thus ensuring the drying effect of the foam board.

[0035] Each of the two corners at the bottom of the bundle tube 5 is equipped with a support leg 22.

[0036] Reference Figure 1 and Figure 2 The outriggers 22 provide stable support for the entire device, thereby ensuring the stability of the device during operation. At the same time, they can also isolate the device from the ground to reduce heat loss inside the device.

[0037] Working Principle: When using this device, the gas inside the drying chamber 1 is heated by the first heating rod 2 and the second heating rod 21. The foam board is placed at the inlet of the front-end bundle tube 5. After the bottom of the foam board is supported by the rotating roller 9, the top of the foam board is pressed by the conveyor roller 12. The front-end conveyor motor 3 is started through the control panel 14. The conveyor motor 3, in conjunction with the drive roller 4, drives the drive gear 10 to rotate. The drive gear 10, in conjunction with the chain 11, drives the transmission gear 13 to rotate. The transmission gear 13 transmits the rotational force of the chain 11 to drive the conveyor roller 12. The rotation of the conveyor roller 12 carries the foam board into the drying chamber 1. A thrust is generated on the sealing plate 7, causing it to rotate around the positioning shaft 6. As the sealing plate 7 rotates, it provides the space required for the foam board to enter the drying chamber 1. After the foam board enters the drying chamber 1, the sealing plate 7 rotates back under its own weight to close the bundle tube 5. The output end of the servo motor 17 drives the baffle plate 18 to disturb the gas inside the drying chamber 1. After heat exchange, the gas at the top is released to the bottom of the foam board through the return pipe 19 and the diffuser 20. During this period, the gas is reheated by the second heating rod 21. The heated foam box exchanges heat with the foam board to dry it. After drying, the foam board is released out of the drying chamber 1 through the bundle tube 5 as the end conveyor motor 3 operates.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
