Product Details

　　Screw parallel automatic extrusion equipmentCorrect stopping sequence:

1. Firstly, we need to feed the twin-screw extruder. Conventional extruders have feeders or feeding systems. When using a multi-channel supply system, it is necessary to stop each auxiliary supply machine.

2. If the twin-screw extruder has a vacuum exhaust system, we need to close the valve of the vacuum pipeline and then open the upper cover plate of the vacuum chamber.

3. The screw of the twin-screw extruder cannot stop rotating directly, and the method of gradually reducing the screw rotation speed should be adopted to remove the residue inside the cylinder as much as possible.

4. When using heat sensitive materials that are prone to thermal decomposition as raw materials for twin-screw extruders, replace the residual materials in the main body with polyolefin materials before stopping, and stop the main body after the materials are basically discharged.

5. Stop the main motor cooling fan, oil pump, vacuum pump, and pump of the twin-screw extruder in sequence. Cut off the power switch of each section heater on the electrical meter control panel and stop auxiliary equipment such as the pellet machine.

　　Introduction to screw parallel automatic extrusion equipment:

A complete set of screw type automatic extrusion equipment consists of a main engine, auxiliary engine, and control system. The extruder is the main equipment for plastic extrusion molding, which consists of an extrusion system, a transmission system, a heating and cooling system, and a host control system.

1. The extrusion system, consisting of a barrel, screw, and hopper, is the core working part of the extruder.

2. The transmission system consists of a motor, a speed control device, and a transmission device. The function is to provide the required speed and torque to the screw.

3. The heating and cooling system consists of temperature control equipment. The function is to heat and cool the barrel to ensure that the extrusion system is formed within the temperature range required by the process.

4. The control system mainly consists of instruments, electrical appliances, and actuators. The function is to regulate and control the barrel temperature, head pressure, and screw speed.

Maintenance and upkeep:

1. Regularly inspect the lubrication system. The lubrication system is crucial for normal operation. During use, the oil level and quality of the lubricating oil should be checked regularly, and the lubricating oil should be replaced and added in a timely manner. In addition, the lubrication system should be regularly cleaned to ensure that the lubricating oil is unobstructed.

2. Regularly inspect the electrical system. The electrical system is crucial for normal operation. Regularly check whether the connections of electrical components are secure, whether the wires are worn, and whether the control system is working properly. If any abnormal situation is found, it should be repaired or replaced in a timely manner.

3. Regularly clean the screw and cylinder. After a period of use, some residues will accumulate in the screw and cylinder, affecting their normal operation. Therefore, regular cleaning of the screw and cylinder is very necessary. When cleaning, appropriate cleaning agents and tools can be used to remove residues.

4. Regularly inspect the cooling system. The cooling system plays an important role in controlling the temperature of equipment. Regularly check the flow and temperature of the cooling water to ensure the normal operation of the cooling system. If insufficient cooling water flow or abnormal temperature is found, the cooling system should be cleaned or replaced in a timely manner.

5. Regularly inspect safety protection devices. Safety protection devices are important equipment that ensure the safety of operators. Regularly check whether safety devices such as safety doors, emergency stop buttons, and limit switches are working properly, and perform necessary repairs or replacements.
