Chenille controller

The system is highly integrated with high-speed brushless motor and stepping motor drive control technology. At the same time, the motor closed-loop control algorithm is introduced. The machine transmission part is driven independently by the motor and can adjust the speed steplessly. The production efficiency is high, meeting various spinning forming requirements, and solving the problems of large spindle difference, high noise, low yarn quality, etc. caused by the belt transmission of the transmission machine.

Digital winding and ranging control system

The system highly integrates high-speed precision servo, brushless DC, stepping motor drive control technology, and introduces high-speed traverse servo yarn guide motion control and online constant tension closed-loop control algorithm. It has been widely used in the winding and traverse winding control of spinning winding equipment such as precision winding winders, stranders, doubling machines, and air wrapping machines to achieve highly flexible digital winding functions, It improves the winding performance and package quality of the machine, and is the best choice for yarn winding equipment.

Rewinder control system

According to the winding process characteristics of the winding equipment of the plastic wire drawing unit, our company integrates many technologies such as constant tension system and field bus communication, and adjusts the speed of the winding motor in real time through the change of the tension sensor, so as to ensure the uniform tightness and tightness of the winding forming and meet the user's needs.

QT series intelligent control module

QT series integral partial rotary valve electric device is used for 90 ° rotary valve. The product has small volume, light weight, high efficiency, high reliability, and can be operated on site or controlled remotely.

New fine and small control module

The fine and small intelligent modules are widely used in petroleum, chemical industry, electric power, metallurgy, pharmacy, paper making, energy, water treatment, shipping, textile, food processing, building automation and other fields. At the same time, it has many advantages, such as small volume, light weight, beautiful appearance, unique and compact structure, easy installation, small operating torque, convenient operation, digital display valve position, no maintenance, safe and convenient use, etc.

DZW type aluminum case intelligent control module

DZW series multi turn valve device is the driving equipment for valve opening, closing or regulating control. DZW type electric device is used for the hoist to make linear motion or with the turbine deceleration part for the hoist to make partial rotary motion, and it can be used to match the valve, which can realize remote control, centralized control and automatic control of the valve.

DZW type iron case intelligent control module

DWZ rotary modular multi turn electric actuator is a very important field driving device in the industrial process control system. Its energy is convenient to use, simple to install and debug, and is increasingly widely used in electric power, metallurgy, petroleum, chemical and other industrial sectors.

Single-ring absolute encoder

The 12 bit single turn absolute value encoder uses intelligent magnetic sensing elements to convert mechanical rotation or angular displacement into electrical signals through three-axis Hall technology for non-contact measurement. Its products have high resolution, good temperature stability, and are widely used in industrial automatic measurement and monitoring systems, especially for occasions where mechanical changes are frequent, the environment is harsh, and the sensor is required to have a long service life and high reliability.

Multi-ring absolute encoder

The multi turn absolute encoder is specially developed for the actuator industry and automation industry. It can measure and remember the absolute position of the angle. The rotation angle and the number of rotation cycles are unique within the range.

Photoelectric yarn sensor

Photoelectric yarn sensor is a high-precision, non-contact photoelectric weft sensor, which is suitable for winding, twisting, doubling and synthetic fiber deformation and other textile processes. The photoelectric yarn sensor is a kind of wire breaking sensor which is easy to use and install. It can detect the operation of various types of spinning on the spinning machine (linear operation, reciprocating operation and annular operation).

Hall sensor

Hall sensor is a high-precision, non-contact magnetic induction sensor, which is suitable for winding, twisting, merging and synthetic fiber deformation and other textile processes. It can detect the running speed of various types of spinning on the spinning machine. It is suitable for winding, twisting, doubling and synthetic fiber deformation, winding machine and other textile processes.
