The working principle of the packaging production line
The packaging production line includes many packaging machinery, such as conveyors. Simply put, the packaging production line is a kind of machinery that we transport products for production during production, which is the packaging production line. For example, the baler is also one of them, so what are the differences between the unmanned baler and the fully automatic baler? The working principle of the conveyor is to use the open sliding tip as coal, ore or material, etc. to form a scraper chain. As a traction component? When the head drive motor is started, it is driven by the hydraulic coupling, reducer, and driving sprocket. The sprocket on the head shaft of the driven motor rotates. The chain circulates and the animal material moves along the conveying direction until it reaches the head of the machine to unload. The scraper chain runs steplessly in a closed loop. The conveying of materials is completed. The characteristics of the combined operation of the electric motor and the hydraulic coupling: ①Improve the parking performance of the scraper conveyor. Start the motor with light load, low starting current, and shorten the starting time: Improve the starting performance of the cage motor. It can make full use of the motor overload capacity and start smoothly under heavy load? ②It has good overload protection performance. When the scraper conveyor is overloaded, part of the working fluid enters the auxiliary chamber, making the motor not overloaded. When the scraper conveyor is stuck or continuously overloaded, the worm wheel is blocked or the speed is very low, the slip between the pump wheel and the worm wheel reaches or approaches a large value, and the temperature of the working fluid rises due to the internal friction force. When the melting point of the molten alloy protective plug (120?丨40'C), the alloy plug melts, the working fluid is sprayed out, the fluid coupling no longer transmits energy and torque, and the scraper conveyor stops running. The motor runs idly to protect the motor and Other working parts. ③It can slow down the impact of the transmission system. The fluid coupling is a non-rigid transmission, which can absorb vibration, reduce impact, make the working mechanism run smoothly, and improve the service life of the equipment. It can make the load distribution tend to be balanced when multiple motors are driven. Because the mechanical characteristics of the motors of the same model are also different, the load distribution will be uneven. After the hydraulic coupling is used, the motor characteristic curve is replaced by the motor-hydraulic coupling combined soft output characteristic curve, which reduces the motor load difference. Improved uneven load distribution. Then by adjusting the filling amount of each coupling, the load distribution can be balanced.
