The film blowing machine is a kind of equipment that heats and melts plastic particles and blows them into a film. It is mainly composed of two parts: film blowing and winding. The function of the winding part is to wind the blown film into a roll, and make the rolled film flat and wrinkle-free, the curling edge is neat, and the film on the reel should be moderately tight to prevent stretching and deformation of the film and ensure quality. Therefore, constant tension control must be used when winding. At present, torque motors are mainly used in the industry to achieve the above-mentioned control, but there are disadvantages that manual adjustment is required during use, and the operation is inconvenient. The torque motor generates high heat during long-term operation, and its controller is easily damaged and has low reliability. . This article intends to use the Pineer inverter to introduce a constant tension control system for film blowing machine winding, which can significantly improve the ease of operation and reliability of the equipment while ensuring the winding process.

Wire drawing machine is one of the main processing equipment in the wire and cable industry. It mainly processes copper wire into various specifications of thin wires. It is generally composed of pay-off, water-cooled, wire-winding and wire-arranging parts. The electric drive part mainly consists of pay-off Realization of motor, take-up motor and arranging motor. With the continuous promotion of frequency conversion technology, frequency converters are increasingly being used in wire drawing machine equipment.

1. Robin Kang frequency converter is widely used in air compressors, energy saving and environmental protection. The dedicated inverter for air compressors has received great welcome from the market. There are many types of air compressors, including piston air compressors, screw air compressors, and centrifugal air compressors, but almost all of their air supply control methods use loading and unloading control methods. Although the air supply control method is simple in principle and easy to operate, it has many problems such as high energy consumption, easy damage to the intake valve, and unstable air supply pressure. With the development and progress of society, high-efficiency and low-consumption technologies have attracted more and more attention. Whether the frequency conversion speed regulation technology can be applied in the field of air compressor air supply to save power while improving air compressor performance and air supply quality has become a topic of our concern.

Extruder is the basic equipment of plastic industry and chemical fiber industry. Many materials such as clay, food, metal, plastic, etc. can be extruded. The most common extruder is a screw extruder. Introduction to Extrusion Machinery:
