Abstract
Description
Technical Field
[0001] This invention relates to a ring spinning machine, specifically to a four-motor drafting transmission device for a CNC ring spinning machine. Background Technology
[0002] Ring spinning frames are indispensable textile machinery in the spinning process and are among the most widely used in textile mills. In order to produce a specific quantity of sliver using the drafting rollers in a ring spinning frame, it is essential to maintain a certain ratio of rotational speed among the drafting rollers and a certain distance between them. For example... Figure 3 As shown, the drafting roller drive mechanism of a conventional ring spinning frame is as follows: a main drive motor drives the front gear drive device through a two-stage belt drive mechanism and a single-stage gear drive mechanism. The power of the front gear drive device is input from the front power gear and outputs in three paths. The two side paths drive the front rollers on both sides through the meshing of driven gears. The middle path outputs directly through the drive shaft of the front power gear to drive the intermediate gear drive device. The intermediate gear drive device outputs power to drive the middle and rear gear drive devices. The power of the middle and rear gear drive devices is input from the middle and rear power gears and drives the middle and rear rollers to rotate through gear meshing. The conventional drafting roller drive mechanism is installed at the head of the ring spinning frame. The main drive motor is mounted on the bottom plate of the head, the front gear drive device is mounted on the front wall plate of the head, and the middle and rear gear drive devices are mounted on the small wall plate of the head. The traditional drafting roller drive method of this ring spinning frame has the following three shortcomings: First, when changing spinning process parameters in the spinning mill, adjusting the drafting roller ratio and the drafting roller spacing requires adjusting multiple transmission gears, making the work of equipment managers complicated and inefficient. Second, with the application of digital design concepts and the emergence of new spinning processes, such as stepless drafting ratio adjustment, real-time computer networking production, and slub yarn, this traditional drafting roller drive method cannot achieve these features. Third, the drafting roller drive mechanism is installed at the head of the spinning machine, driving the front roller, middle roller, and rear roller to rotate towards the middle and rear of the machine. As the number of spindles in the ring spinning machine increases, the length of the drafting roller also increases. Such long rollers are prone to torsional vibration during the drafting process, forming mechanical waves that affect yarn quality.
[0003] As ring spinning frames continue to develop towards digitalization, automation, and extra-long carriages, the design concept of CNC long carriage ring spinning frames has been introduced. Therefore, it is imperative to design a new type of in-car drafting roller transmission device suitable for CNC long carriage ring spinning frames to solve the problems existing in the drafting roller transmission device of traditional ring spinning frames. Summary of the Invention
[0004] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a four-motor drafting transmission device for a CNC ring spinning machine. This device features a novel structure, practical function, and a rational in-machine transmission that enables bidirectional roller drafting drive from the center of the machine to the front and rear, eliminating mechanical waves caused by torsional vibration and improving yarn quality. The rational four-motor layout allows for convenient and quick adjustment of the drafting ratio, simplifying operation and improving work efficiency. It also enables stepless adjustment of the drafting ratio, has a reasonable and compact transmission structure, a short transmission route, precise transmission, and low production cost.
