Automatic large extrusion blow molding machine before starting

As for the preparation before starting the automatic large hollow blow molding machine, Deman extrusion blow molding machine has mentioned it in the previous instruction manual of the large plastic hollow blow molding machine.

Because of hollow blow molding machine, preparation before starting really is necessary, even for production process of hollow blow molding machine in the future will have a direct impact, therefore, this article, we will fully automatic large hollow blow molding machine, ready to do further analysis and discussion, before starting to spread some large hollow blow molding machine operation procedures correctly, said will each step in detail as possible, In order to help you easily complete the machine before starting the preparatory work.

Large hollow blow molding machine before starting

1. Open the cooling water of the cooling cylinder of the hollow blow molding machine. Pay attention! Need to open all, so as to avoid the occurrence of screw bite phenomenon; At the same time, also check the cooling water and start-up system. Make sure water and air do not clog and leak.

2. Preheat the hydraulic oil. If the temperature of the hydraulic oil in the tank of the hollow blow molding machine is too low, the heater needs to be turned on.

3. Press the start button of the hollow blow molding machine and then stop it immediately to check whether the pump is running in the correct direction. If any deviation is found, the power cord of the two-phase connecting motor should be replaced immediately.

4. When starting the hollow blow molding machine, it should ensure that the hydraulic system is under the condition of no pressure. After starting the machine, the pressure of the overflow system of each pump should be adjusted to the pressure value meeting the operation requirements. There are often two pressure systems in the large hollow blow molding machine, one is the closing unit, the other is the blow molding unit, and each of the two units has a pressure vent valve. After the pump stops, the pressure vent valve needs to be opened. When the pump is working, the pressure vent valve needs to be closed.

5. Adjust the position of all travel switches to make the moving template running switch smooth.

6. Switch on the heating and temperature regulation system.

7. Install the mold matching the hollow blow molding machine. Before installing the mold, clean the surface of the mold and the contact surface with the template of the hollow blow molding machine.

The above are some checks to be done before starting the large hollow blow molding machine. After the above problems are checked, we need to do the following:

Basic parameter check and position calibration of large hollow extrusion blow molding machine

1. Clean and lubricate the moving parts and fasteners, and tighten them in time if they are loose.

2. Check the heating time. Different device areas should set different heating time.

3. Check the pressure of the air compressor. The range is 0.8Mpa-1Mpa.

4. Check the water pressure of the mold and extruder.

5. Check and turn on the water system.

6. Adjust the gap of the die evenly and check whether the standard line of the main machine and the auxiliary machine is aligned.

7. Start the extruder, die locking device, manipulator and other operating equipment to carry out load free operation, check the normal operation of each emergency device, and remove the fault in time.

8. Set the temperature of the head and each heating section of the extrusion blow molding machine according to the regulations of the process conditions, and heat it stage by stage.

In addition to the preparation before starting the large hollow extrusion blow molding machine, the raw materials used for the production of hollow blow molding machine are equally important. What we need to do is to make sure that the raw materials we use meet the drying requirements of the production standard, if not, we need to further dry.

Here I want to give you an extra expansion about hollow blow molding products. Sometimes, even if we operate the machine correctly according to the operation manual of the hollow blow molding machine, the products produced will have all kinds of problems.

Note that technicians responsible for the production of hollow blow molding machine need to be trained in the operation of hollow blow molding machine before they can officially work.

Because the entire production process of the automatic large hollow blow molding machine is automatically completed in one step, any mistake in the production process will lead to production interruption. Therefore, it is very important to do a good job in the preparation before the start of the large hollow blow molding machine, and no sloppiness can be tolerated.
