Abstract

The invention provides a one-step composite twisting frame, and belongs to the technical field of textile machinery. By arranging an unwinding device on the top of a first twist spindle, the problemsthat in the yarn twisting process, uneven yarn twist, fuzzing, bubbling and the like are caused by unstable balloon tension can be effectively solved. The one-step composite twisting frame comprises afirst twisting mechanism, a roller transmission structure and the a second twisting mechanism; in the first twisting mechanism, single twisting is conducted through the first twisting spindle, and two or more yarns completing single twisting enter the roller transmission structure for monofilament stranding to form a twisted yarn; the second twisting mechanism is used for second twisting of the twisted yarn; the unwinding device is arranged on the top of the first twist spindle, that is to say, a bracket is additionally arranged in the middle of a twisting zone of the yarns, the size of a balloon formed through high-speed rotation of the yarns in the twisting zone is fixed, the balloon size is basically the same, and the yarn quality problem generated by colliding with other parts cannotbe caused; the problems of yarn fuzzing, bubbling, more white dots, more broken ends and the like of a traditional one-step twisting frame can be effectively solved.

Description

technical field

[0001] The invention relates to a textile machine, in particular to a twisting machine, which belongs to the technical field of textile machines. Background technique

[0002] In the textile industry, the function of the twisting machine is to combine and twist several raw material (PP) monofilaments into one strand of yarn after initial twisting and double twisting. During the twisting process of the fishing net line (PE), the rotation speed ranges from several thousand to tens of thousands of revolutions per minute, which will form a ring-shaped closed air circle that expands outward. This air circle will be affected by twisting time, winding quality, The influence of bobbin quality and other changes; at present, yarn separators or balloon rings are used to control the change of yarn balloons in the initial twisting, and the tension of the balloons is unstable, which may easily cause the balloons to fail to open or the balloons to be too large to hit the is...
