Solution Overview

Problem

Existing textile machines with single-motor driven spindles face inefficiencies in energy consumption due to idle spindle rotation during yarn breakage and lack of independent control, and the mounting process is inconvenient due to complex steps and placement of the motor stator component.

Innovation Solution

A textile machine design featuring a spindle with a spindle rod seat, motor stator component, and a positioning sleeve that allows for simple and efficient mounting through a threaded or pinned connection, reducing energy waste and enhancing operational convenience by integrating the motor stator housing and mounting portion directly to the spindle rod seat.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If spindles are integrally driven by a tangential belt, then the driving structure is simple, but the spindles cannot be independently controlled and continue rotating during yarn breakage causing energy waste

Engineering Contradiction:
Improvedriving structureVSAvoidenergy consumption
Core Design Contradiction:
Device complexityVSLoss of energy

Solution Approach 1:

The patent divides the driving system into independent units by replacing the integral tangential belt drive with individual motors mounted on each spindle. Each spindle receives power independently through its own motor, allowing separate control and stopping of each spindle during yarn breakage, thus eliminating energy waste from idle rotation while maintaining structural simplicity through modular design

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements dynamic control capability by equipping each spindle with an independently controllable motor. This allows the system to dynamically adjust the operation state of each spindle based on real-time conditions, such as stopping individual spindles during yarn breakage while keeping others running, optimizing energy consumption without compromising overall system functionality

Inventive Principle:
Principle #15Dynamics

2Ease of manufacture

If the motor stator component is mounted separately from the spindle rod seat, then the motor can be independently replaced, but the mounting steps increase and operation becomes inconvenient

Engineering Contradiction:
Improvemotor replacementVSAvoidmounting convenience
Core Design Contradiction:
Ease of manufactureVSEase of operation

Solution Approach 1:

The patent combines the motor stator component and spindle rod seat into a single integrated assembly where the motor stator is directly mounted on the spindle rod seat. This merging eliminates separate mounting steps and simplifies the overall structure, making installation and maintenance more convenient while preserving the ability to replace the motor unit as a complete module

Inventive Principle:
Principle #5Merging (Combining)

AI summary

The utility model provides a textile machine with single-motor driven spindles, comprising: a frame, and a plurality of single-motor driven spindles disposed on the frame; the spindle comprising a spindle rod seat disposed on the frame, a motor stator component and a spindle rod partially disposed in the spindle rod seat and the motor stator component; the spindle rod being driven to rotate by force generated between the spindle rod and the motor stator component. The motor stator component comprises a motor stator, a housing for accommodating the motor stator and a mounting portion for mounting integrally provided at the housing, and the mounting portion is fixedly connected to the spindle rod seat such that the spindle rod seat and the motor stator component are fixedly connected to the frame. Since the mounting portion and the housing of the motor stator component are integrally provided, the mounting of the spindle can be realized by operating the mounting portion of the motor stator component to be mounted on the spindle rod seat. The operation steps are simple and convenient and the mounting efficiency is high.
