What should be noted for the installation and debugging of ABA blown film machine?

ABA blown film machine is an efficient equipment used for producing multi-layer co extruded films, widely used in packaging, agriculture, construction and other fields. The installation and debugging process is crucial to ensure the normal operation of the equipment and product quality. The following are the key points to pay attention to when installing and debugging ABA blown film machine.

1、 Preparation work before installation

Site selection and preparation

Site requirements: The installation site should be flat and sturdy, and the ground load-bearing capacity should meet the equipment requirements. The site area should be large enough to facilitate the installation, operation, and maintenance of equipment.

Environmental conditions: Ensure that the installation environment is well ventilated, with appropriate temperature and humidity, and avoid the impact of adverse environments such as high temperature, high humidity, and dust on the equipment.

Power supply and gas source: Ensure that the power supply voltage and frequency meet the equipment requirements, the gas source pressure is stable, and necessary power protection devices and gas source filtering devices are equipped.

Equipment inspection

Open box inspection: After the equipment arrives, an open box inspection should be conducted to confirm that the equipment and accessories are complete, without damage or missing.

Basic inspection: Check whether the equipment foundation meets the requirements, ensure that the foundation is level and stable, and avoid vibration and displacement during equipment operation.

2、 Equipment installation

Equipment in place

Lifting and Handling: Use appropriate lifting equipment and tools to ensure that the equipment is smoothly and safely transported to the designated location. During the transportation process, collision and vibration should be avoided.

Positioning and fixing: Place the equipment on the foundation, use a level to adjust the levelness of the equipment, and ensure that all components are aligned. Use anchor bolts or expansion bolts to secure the equipment and ensure its stability.

pipeline connection

Gas path connection: Connect the gas path according to the equipment manual to ensure that the gas path is unobstructed and leak free. After connecting the air circuit, a pressure test should be conducted to ensure that the air circuit system is working properly.

Waterway connection: Connect the cooling water system to ensure smooth and leak free waterways. The cooling water flow rate and temperature should meet the equipment requirements.

Electrical connection

Power connection: Connect the power supply according to the equipment electrical drawing, ensuring correct and secure wiring. After connecting the power supply, insulation testing should be conducted to ensure electrical safety.

Control circuit connection: Connect the control circuit to ensure that all control components are working properly. After connecting the control circuit, a functional test should be conducted to ensure that the control system is functioning properly.

3、 Equipment debugging

Mechanical debugging

Transmission system debugging: Check the tension and lubrication of components such as belts, chains, gears, etc. in the transmission system to ensure smooth operation and no abnormal noise.

Extrusion system debugging: Check the installation of the screw, barrel, heating ring and other components of the extruder to ensure the normal operation of the extrusion system. Adjust the temperature, pressure, speed and other parameters of the extruder to ensure stable extrusion process.

Mold head debugging: Check the installation of the mold head to ensure alignment with the extruder. Adjust the gap, temperature and other parameters of the mold head to ensure uniform film thickness and smooth surface.

Electrical debugging

Control system debugging: Check the operation of components such as PLC, touch screen, sensors, etc. in the control system to ensure its normal operation. Adjust control parameters to ensure stable operation of the equipment.

Safety protection debugging: Check the safety protection devices of the equipment, such as emergency stop button, overload protection, temperature protection, etc., to ensure that the safety protection devices are working properly.

Process debugging

Raw material preparation: Prepare suitable raw materials according to production requirements, ensuring that the raw materials are dry and free of impurities. The ratio and mixing of raw materials should meet the process requirements.

Process parameter adjustment: Adjust the temperature, pressure, speed, traction speed and other process parameters of the equipment according to production requirements to ensure that the thickness, width, transparency and other indicators of the film meet the requirements.

Trial production: Conduct trial production, observe the appearance, thickness, strength and other indicators of the film, adjust process parameters, and ensure stable product quality.

4、 Precautions

safe operation

Operation training: Operators should receive professional training, familiarize themselves with the structure, principles, operation methods, and safety precautions of the equipment.

Protective measures: Operators should wear necessary protective equipment, such as gloves, goggles, etc., to avoid harm caused by dangerous factors such as high temperature and high pressure.

Emergency handling: If any abnormal situation occurs during the operation of the equipment, it should be stopped immediately for inspection and troubleshooting before continuing to operate.

Maintenance

Regular inspection: Regularly inspect the mechanical, electrical, pneumatic, and plumbing components of the equipment to ensure proper operation.

Lubrication and maintenance: Regularly lubricate and maintain the transmission system, bearings, and other components of the equipment to ensure smooth operation.

Cleaning and maintenance: Regularly clean the mold head, screw, barrel and other components of the equipment to avoid impurities affecting product quality.

Record and feedback

Operation record: Record the operating parameters, fault conditions, maintenance and upkeep of the equipment, providing a basis for equipment optimization and improvement.

Problem feedback: If any problems are encountered during the operation of the equipment, they should be promptly reported to the equipment supplier or professional technical personnel to seek solutions.

The installation and debugging of ABA blown film machine is a complex and meticulous process that requires strict adherence to the equipment manual and operating procedures. By proper installation, debugging, and maintenance, the normal operation of equipment can be ensured, and production efficiency and product quality can be improved. At the same time, operators should possess professional knowledge and skills to ensure the safe operation and long-term stable operation of the equipment.
