Today, let's talk about the storage type blow molding machine, also known as the storage type blow molding machine. The editor has sorted out the maintenance of the storage type extrusion blow molding machine for you.
1. Start with the ingredients first. For raw materials, it must be clean and clean. For small stones, sand, especially metals, if they enter the storage blow molding machine, they will get stuck and damage the pressing hydraulic cylinder. Servo hydraulic cylinder seals, etc., require a lot of money and energy to repair, and production is forced to stop during the maintenance period; iron removers can be installed in the barrels and crushers, and the maintenance work of the storage-type hollow blow molding machine can be done well.
2. When feeding, also pay attention to site hygiene and maintain cleanliness.
3. During the reproduction process, the leftover material of the lower storage blow molding machine should be cleaned up in time.
4. When heating the raw materials, be sure to give the blow molding machine a certain preheating time, and heat it to the process standard to maintain a constant temperature for more than 2 hours.
5. The heater of the blow molding machine should be grounded and take measures to prevent electric shock!
6. If the pressure of the storage type blow molding machine is too high, it may be due to factors such as raw materials or design, which lead to the high melt pressure with the extruder, which affects the production efficiency and the temperature rise of the extruder and blow molding machine. high. Therefore, when such a situation occurs, technical trimming is required. The head of the blow molding machine can be removed, and the flow channel of the blow molding machine can be overhauled and polished. If you do not have confidence in yourself, you can perform maintenance on a small scale each time, and gradually meet the specified requirements.
7. What problems should we pay attention to when replacing the color material in the head maintenance of the storage type hollow blow molding machine? How can we shorten the time for changing the colorant?
1) You can add an appropriate amount of water to the raw materials, but don’t overdo it! The purpose of this is to be able to generate air bubbles in the storage blow molding machine, increase the melt pressure, and shorten the color change time.
2) Manually adjust the pressure in the hydraulic cylinder of the pressing material, increase the melt time and shorten the refueling time.
3) When changing the color material, the color material in the blow molding machine and the barrel should be cleaned to prevent it from entering the extruder again. This is also a small method to speed up the color change.
4) The blow molding machine with long-term material change can be technically modified, and computer engineering software is used to analyze and improve the various parts of the blow molding machine. It can also speed up the color change.
8. Carry out spot inspection and maintenance of the storage blow molding machine every day, and make written records.
The above are the eight maintenance points of the storage-type hollow blow molding machine. For the storage-type blow molding machine, it is necessary to not only maintain it but also pay attention to cleaning, because many polymeric plastics will stay in the head of the blow molding machine when the temperature is high. For a period of time, and the melted polymer plastic will accumulate on the head of the runner, resulting in streaks in the produced product, so the cleaning of the machine head is particularly important and must be paid attention to! This article gives you a simple and practical way to clean the storage head.
