TEXTILE MACHINE WITH SINGLE-MOTOR DRIVEN SPINDLES

Description

[0001] The invention relates to the field of textile machines, in particular to a spinning frame with single-motor driven spindles.

[0002] In existing textile machines, such as ring spinning frames, each usually comprises a plurality of spinning stations arranged side by side. Each station comprise independent spindles, and after an empty paper bobbin is disposed to the spindle, the machine runs to wind the yarn on the empty paper bobbin to form a yarn package. The spindles of the plurality of stations for driving the empty bobbins to rotate are usually connected together by a tangential belt to be integrally driven. But in the integral driving, once the spinning is stopped due to yarn breakage or other conditions in a certain station, the spindle at the station still rotates normally since the spindle of the station is connected together with the spindles of other stations for being integrally driven. On one hand, the idle running of the spindle at the station increases the energy consumption; and on the other hand, since the spindle at the station still rotates normally, the broken yarn may be wound thereon, while the integral driving is adverse to the independent control of each station, and driving of the single spindle cannot be adjusted.

[0003] In addition, the spindle in the prior art comprises a spindle rod seat arranged on a frame and a spindle rod rotatably disposed on the spindle rod seat and integrally driven by a tangential belt. When the spindle is to be mounted, the spindle rod seat is fixedly mounted on the frame by nuts, and then the spindle rod is mounted on the spindle rod seat. Since the single-motor driven spindle is provided with a motor stator component outside the spindle rod, when the original mounting mode is applied to a spinning frame with single-motor driven spindles, the mounting steps will be increased, and the operation will be inconvenient.

[0004] Document EP 1 154 141 A1 discloses a textile machine according to the preamble of claim 1. The textile machine has a housing for accommodating a motor stator, wherein the housing is fixed to a mounting portion by press fitting which is fixed to a frame by press fitting.

The drive motor has a housing composed of a motor supporting portion and a mounting portion mounted at the lower end of the motor supporting portion to rotatably support a spindle shaft via a bearing on a frame. The mounting portion is fitted to each of the motor supporting portion and the frame by screw fastening means.

[0006] Therefore, it is necessary to improve the spindle mounting structure of the existing textile machine with single-motor driven spindles.
