Double-output-shaft motor driven two or three roller drawing frame

By using a dual-head servo motor drive and synchronous belt transmission structure, combined with servo control and cooling protection components, the problems of low synchronization accuracy and poor structural stability in existing technologies have been solved. This has enabled high-precision synchronization of the rollers and stability of the transmission system, thereby improving the overall performance of the drawing frame.

AI Technical Summary

Technical Problem

Existing dual-output-shaft motor drive schemes are mostly single-sided drives, failing to achieve integrated synchronous control of symmetrical rollers, making it difficult to balance structural compactness and operational stability.

Method used

The system employs dual-head servo motors to drive drive wheel one and drive wheel two respectively. Through a combination of synchronous belt and transmission wheel structure, along with a servo controller, encoder, and swab tension sensor, it achieves synchronous precision control of the middle roller and rear roller. Cooling and protection components are also provided to improve system stability.

Benefits of technology

It improves the synchronization accuracy of the rollers, reduces the CV value of the sliver evenness, ensures the stability and cooling efficiency of the transmission structure, protects the transmission components, and enhances the overall performance of the drawing frame.

Abstract

This invention relates to the field of textile machinery and discloses a dual-output shaft motor-driven two- and three-roller drawing frame, comprising a fixed base. A dual-head servo motor is fixedly connected to the outer wall of the fixed base. The teeth of the first drive wheel are meshed with a first synchronous belt, and the teeth of the second drive wheel are meshed with a second synchronous belt. A front roller, a middle roller, and a rear roller are rotatably connected between the roller bench and the roller base. Tensioning wheels and limiting wheels are rotatably connected to the outer walls of both the roller bench and the roller base. A cooling assembly is provided on the outer wall of the fixed base, and protective assemblies are provided on the outer walls of the roller bench and the roller base. Through the first and second drive wheels on both sides of the dual-head servo motor, they are indirectly connected to the middle roller and the rear roller through a transmission structure including the first synchronous belt, the fixed base, the second synchronous belt, and the second transmission wheel. The dual-output shaft motor is controlled by a closed-loop encoder, which improves the synchronization accuracy of the rollers and reduces the CV value of the sliver evenness.
