Hot melt adhesive coating machine discharge unit material change method (3).

When the discharge unit of the Hot melt adhesive coating machine needs to change materials, press the receiving button, the discharge storage rack motor accelerates, and the discharge traction motor slows down. In this process, the discharge traction pendulum roller controls the discharge traction motor, the discharge storage rack motor follows the speed of the main engine, and when the speed of the discharge storage rack = the speed of the main engine, the speed of the discharge traction motor is reduced to 0. At this time, the discharge traction pendulum roller of the hot melt adhesive coating machine is switched from the original control discharge traction motor to the control of the discharge storage rack motor, so as to ensure the stable discharge tension and smoothly stop the zero-speed material connection.
