Brief introduction to the characteristics of automatic winding machine belt drive system of automatic winding machine manufacturers

The automatic winding machine of Zhengtaifeng automatic winding machine manufacturer is divided into two parts: winding and arranging, so the transmission part of the automatic winding machine is also independent. The transmission of the winding part is to transfer the rotation of the motor to the chuck, so that the chuck can rotate according to the research and development of the computer automatic winding machine at the established speed, and complete the winding action. The transmission of the wire arranging part is to convert the rotation of the stepping motor into translation and arrange the wire according to the technical requirements. The load and accuracy of the two parts are different. The winding part requires high speed and heavy load, but the accuracy requirement is not high, while the winding part requires low speed and light load, but the accuracy requirement is high. Therefore, in the whole structural design, the design of transmission system is related to the accuracy, efficiency and reliability of the whole system.

Belt transmission is a mechanical transmission that uses intermediate flexible belt to transmit motion and power. The belt drive consists of a master wheel and a slave wheel, and a belt tightly sleeved on the two wheels. According to the working principle, belt drive can be divided into friction drive and meshing drive. There are flat belt drive, V-belt drive, circular belt drive and wedge belt drive that transmit motion and power by friction, and the difference between them is the different cross-sectional shape; The synchronous belt transmission relies on the engagement of the convex teeth on the inner surface of the belt with the tooth grooves on the pulley to transmit motion and power.

The annular inner surface of the flat belt drive belt is pressed against the outer surface of the pulley to generate friction. Common flat belts include canvas core flat belts, leather flat belts, woven flat belts and composite flat belts. Generally, the joint is connected into a ring, so the transmission is not stable enough. Because the flat belt is soft and can be twisted, it can be divided into three transmission forms according to the relative position and rotation relationship of the shafts in low power transmission: open transmission-two shafts are parallel and have the same rotation direction, which is a common form; Cross drive-two shafts are parallel and turn in opposite directions, which is used to change the direction of rotation; Semi-cross drive-two shafts are crossed, and the crossing angle is usually 90 degrees, which is used to transmit the rotation between two staggered shafts in space. The belt is in a semi-cross state and is only suitable for one-way drive.

The axial compression motor of the compression force compression device is controlled by a high-function frequency converter, and the radial compression motor is a compact servo deceleration motor, and both axial and radial compression are fed back by a high-precision encoder to realize closed-loop control, so the controlled compression force has high precision, linearity and smoothness. The automatic winding machine not only has the function of limiting and protecting the moving limit position, but also has the function of automatically identifying obstacles, that is, the pressing device can find objects that may conflict with the pressing roller in advance during the moving process, and slow down or contain them in advance to ensure that the coil is not damaged, and also ensure the safety of equipment and people.

The closed-loop vector control frequency converter with wide winding coil diameter and high function can control the spindle motor drive, which can realize stepless speed regulation between 0 and 0～10.0rpm at the moment, effectively overcoming the common problems of low transmission efficiency, high noise and high failure rate of traditional winding machines. It has forward and backward counting function and power-off memory function. When the preset number of turns is reached, the equipment automatically stops and sends out prompt information to ensure the accuracy of winding turns. In the process of winding the coil, the pressing device can supply predetermined axial and radial pressing forces.
