[0002] In aluminum profile processing equipment, the aluminum rod needs to be heated before extrusion. Usually, the aluminum rod is heat treated in an aluminum rod heating furnace, that is, the aluminum rod is heated by burning natural gas in a burner. In order to make the aluminum reach the specified temperature, the temperature of the space inside the furnace is usually detected. Generally, the temperature detection device is set on the furnace cavity or inner wall. Although it can detect the accurate temperature in the furnace, it cannot accurately reflect the actual temperature of the aluminum rod. Especially in continuous production, the temperature in the furnace is high, and the new material enters at a low temperature. The aluminum rod needs a period of heating time to reach the temperature in the furnace. It is impossible to accurately control the temperature of the aluminum rod and the quality of the aluminum profile. The temperature detection of the aluminum rod is mainly carried out manually or with a simple detection device. The obtained aluminum rod temperature data is inaccurate and unstable, which may cause the quality of the aluminum profile to be unstable, which needs to be improved urgently. Summary of the invention

The microprocessor is communicated with the control system in the electric cabinet; the discharge table is connected with the aluminum rod shearing machine.

[0007] When in use, the aluminum rod falls from the aluminum rod placement rack into the feed table, and is driven by the feed conveyor roller to move toward the heating furnace and enter the heating furnace from the rod furnace inlet; while heating the aluminum rod, the aluminum rod is evenly heated while moving toward the rod furnace outlet on the aluminum rod channel. When the aluminum rod extends from the rod furnace outlet into the discharge table, the infrared temperature sensing device located on the outer surface of the furnace body measures the temperature of the aluminum rod by utilizing the infrared radiation heat effect, that is, the infrared temperature sensor measures the temperature of the aluminum rod, obtains the outlet temperature of the aluminum rod heating furnace, and realizes accurate detection of the outlet aluminum rod temperature. The infrared temperature sensor transmits the temperature data The temperature is transmitted to the microprocessor. If the microprocessor determines that the measured temperature is within the set temperature range, no processing is performed. If the microprocessor determines that the temperature is lower than the specified temperature range, that is, when the temperature of the aluminum rod out of the furnace is measured to be too low, the microprocessor feeds back to the control system and adjusts the temperature in the heating furnace, that is, increases the temperature in the heating furnace. Similarly, through continuous temperature adjustment, the temperature of the aluminum rod is controlled, and more precise temperature control is achieved to ensure the stability of the thickness and hardness of the coarse-grained layer of the aluminum profile.
