Operating procedures of powder coating equipment

* * * There are four steps. 1. Premix: Weigh the raw materials according to the formula and add them into the premix tank. Generally speaking, the premixing tank has four buttons, the switch is used for stirring and the switch is used for crushing. Note that the materials should not be mixed too much at a time, and it is best not to exceed the rated load. Too much material is easy to damage the motor and make it mix unevenly. It is best to stir for more than 3 minutes for the first time, and it can be stirred for 2 minutes after 2 times. Generally, it is enough to stir alone. Except for special powder, there is no need to turn on the grinding motor.

The second is extrusion, the extrusion process is relatively simple, pay attention to the temperature of the extruder, and generally adjust the temperature to automatic temperature control. Generally, the set temperatures for outdoor products are 105℃ in the first zone,10℃ in the second zone, 90℃ in the first zone and 100℃ in the second zone. After the temperature reaches the set temperature. Turn on the circulating water, tablet motor and tablet speed regulator. There are many kinds of governors, and only one function is cooling and crushing to achieve appropriate results. It doesn't matter whether you walk fast or slow. After opening the graphics tablet, start the main screw, and adjust it when the main screw rotates between 38 and 45 under special circumstances. When the screw current shows normal, the feed motor can be started. The amount of feed mainly depends on the bearing capacity of the screw main motor and so on. The characteristics of one product are different from those of another product, so the feeding is inconsistent, which needs to be debugged in actual operation. When the machine is turned off, the operation can be reversed. After the feed is closed, be sure to rush the car. If you don't hurry the car, it won't start next time.

Mill, the mill is a first induction ventilation motor. Only after the current of the induced air motor returns to normal can the rotary screen motor and the discharge valve motor be started, and then the auxiliary mill motor can be started. After the auxiliary mill turns to the set value, the main mill motor can be started again, and then the feeding can be started. The settings of the auxiliary mill and the main mill are determined by the technicians after adjustment. Sometimes, the value of feeding has a great relationship with the performance and appearance of products. Needless to say, give points. Playing with your hands is very tiring.
