1. Firstly, check whether the mixer works normally. Firstly, turn off the power supply of the mixer, put the raw materials, master color and toner with good ratio into the mixing bucket, cover the mixing bucket, and turn on the power switch of the mixer after checking the correctness.
2. To check whether the refrigerator is working normally, first turn on the motor switch of the refrigeration system to see whether the motor is running normally, then turn on the water tower switch to check whether the water supply is normal, set the temperature of the refrigerator, and start the refrigerator.
3. Check the circuit and waterway of the mixer every day. No sundries can be stacked around the machine to ensure the safety of the production environment. The hollow blow molding machine checks the mechanical part, electrical part, hydraulic pressure, water and air way every day.
4.Preheating of blow molding machine: before heating, the cooling water of the feeding section of the machine bucket must be connected. During the heating process, check whether the connection of each heating wire is correct and reliable. During the heating process, pay attention to whether the temperature displayed on the touch screen is normal (generally, the heating time is 3-4 hours).
5. Check whether the machine is normal before starting, and start the main oil pump. The oil temperature is between 35 and 55 degrees. Start the oil pump idle for 30 minutes to clean the oil circuit system without load.
6. Feeding, start the hanging motor, check again whether the temperature of the barrel and die head reaches the working temperature, whether the hanging material is stable.
7. Manually shoot material and strangle material, after normal check blowing needle and die head blowing is normal. Set the hydraulic system to 0.4-0.6mpa and the top blowing pressure to 0.2-0.4mpa
8. Press the semi-automatic and start button to trial produce products. According to the conditions of trial production products, time the injection length, weigh and measure the wall thickness, and confirm the quality of products with quality control before mass production.
Points for attention:
1) The hollow extrusion blow molding machine is a high voltage and strong current electrical equipment, and non-professional personnel are not allowed to maintain, disassemble and measure it. Prevent high voltage electric shock.
2) The mold of the hollow blow molding machine must be installed by crane, and the operation of the crane shall be in accordance with the operation rules of the crane. No part of the worker's body should be near the mold area during the working process and the molding process. When the machine IS moving the mold to open and close the mold, the operator and bystanders should not enter the safety door area or open the safety door to avoid injury.
3) Pay attention to the safety protection and maintenance of all moving and rotating parts of the machine. Pay attention to the warning signs everywhere and press the red emergency stop button in case of emergency to prevent accidents.
4) Prevent high temperature scald in the heating part during heating.
5) After the work, cut off the power supply, and clean and maintain the machine.
