[0020] The loading platform 1 is provided with a first sprocket 11, a motor 12 and a furnace body 13. The furnace body 13 is provided with a second sprocket 14. The motor 12 drives the first sprocket 11 and the second sprocket 14 to rotate synchronously in the same direction.

[0021] The material cart 2 moves between the loading platform 1 and the furnace body 13 , and is provided with a rack 21 meshing with the first sprocket 11 and the second sprocket 14 .

[0022] From the above description, it can be seen that the beneficial effects of the utility model are: an aging furnace loading structure, after the furnace is filled with aluminum profiles, the driving motor 12 traction control drives the first sprocket 11 and the second sprocket 14 to rotate synchronously in the same direction, and the rack 21 of the material cart 2 is engaged with the first sprocket 11, so as to transport the material cart 2 to the furnace body 13. When the material cart 2 moves and contacts the second sprocket 14 in the furnace body 13, the first sprocket 11 and the second sprocket 14 jointly drive the material cart 2 to continue to transport. When the first sprocket 11 outside the furnace is separated from the material cart 2, the second sprocket 14 in the furnace drives the material cart 2 alone to complete the loading. The material cart 2 adopts this loading method. Not only is the loading process stable and smooth, but also compared with the single sprocket drive loading method, it can reduce energy consumption by at least 20%, which is beneficial to reducing the power consumption of aging. In addition, the loading structure of the utility model can also increase the single loading amount. The load capacity of the material cart 2 is increased from the original 16 tons to 30 tons, which helps to improve production efficiency.

[0023] In an optional embodiment, the output shaft of the motor 12 is provided with a first output wheel 15 and a second output wheel 16 , the first output wheel 15 is connected to the first sprocket 11 through a double-row chain, and the second output wheel 16 is connected to the second sprocket 14 through a double-row chain.

[0024] From the above description, it can be seen that the motor 12 synchronously drives the first sprocket 11 and the second sprocket 14 to rotate in the same direction at the same speed through the first output wheel 15 and the second output wheel 16, thereby improving the stability and continuity of the operation of the trolley 2.

[0025] In an optional embodiment, a first tensioning wheel 17 is connected between the motor 12 and the first sprocket 11 , and a second tensioning wheel 18 is connected between the motor 12 and the second sprocket 14 .

[0026] From the above description, it can be known that the functions of the first tensioning wheel 17 and the second tensioning wheel 18 are to adjust the tension of the transmission chain, so as to ensure the stable operation of the sprockets.

[0027] In an optional embodiment, a lifting furnace door 131 is provided on a side of the furnace body 13 facing the first sprocket 11 , and the lifting furnace door 131 is located between the first sprocket 11 and the second sprocket 14 .

[0028] From the above description, it can be seen that the furnace body 13 adopts a lifting furnace door 131, which opens upward when the material car 2 passes, thereby improving the safety of the loading operation.

[0029] In an optional embodiment, guide rails 19 are provided on the loading platform 1 and the furnace body 13 , and the material cart 2 is provided with wheels 22 that cooperate with the guide rails 19 .

[0030] It can be seen from the above description that the trolley 2 achieves stable transportation through the cooperation between the wheels 22 and the guide rails 19.

[0031] In an optional embodiment, the loading platform 1 is provided with a sinking chamber 101 , and the first sprocket 11 , the motor 12 and the second sprocket 14 are all arranged in the sinking chamber 101 .

[0032] From the above description, it can be seen that designing the sinking chamber 101 to install the first sprocket 11 , the motor 12 and the second sprocket 14 is beneficial to saving the ground space of the loading platform 1 .

[0033] The working principle of the utility model is: S1, start the control power supply. S2, check whether the travel switch, voltmeter, and button are normal. S3, check the temperature control instrument, hot air circulation system, and temperature measuring thermocouple in detail to see if they are normal. S4, lift the furnace door 131, the trolley, start the temperature controller, the fan, and the heating power supply, and only start production after confirming that they are normal. S5, when loading and unloading the furnace, it is forbidden to stand in front of or behind the material basket or under the furnace door. You should stand on both sides, and the weight of the profile must not exceed its design capacity or be higher than the edge of the material frame. S6, when entering the furnace, press and hold the "trolley in" button until it is in place, and then press and hold the "furnace door close" button; conversely, when unloading the furnace, press and hold the "furnace door open" button until it is in place, and then press and hold the "trolley out" button until it is in place. S7, after entering the furnace, the aging switch operation sequence (open) is: fan inverter control → circulation fan start → heating start. S8, the switch operation sequence before aging is finished and unloading (closed): heating stop → circulation fan stop.

Due to the high temperature environment in the furnace, the bearing seat material is processed with A3 plate, and the bearing is a high temperature resistant bearing. The bearing seat is locked on the bottom plate, and the bottom plate is welded on the channel steel of the feeding car 2 frame. The bottom plate and the lower surface of the upper channel steel are welded with vertical ribs to increase its strength. The wheel 22 group, the shafts and holes at both ends of the wheel 22 are worn and cannot be repaired, and the internal bearing 6010 of the wheel 22 is an ultra-light load bearing, which is difficult to replace after damage.
