Double-twisting strander of external take-up and internal pay-off type

Abstract

The invention discloses a double-twisting strander of an external take-up and internal pay-off type. A left main shaft (3) and a right main shaft (4) are connected to the left side and the right side of a rotating body (2) respectively and rotate along with the rotating body (2), a pay-off spool combination (5) is arranged in the rotating body (2), a noseplate (6) is correspondingly arranged on the thread outlet side of the pay-off spool combination (5), one side of the noseplate (6) corresponds to the thread outlet side of the pay-off spool combination (5), a thread pressing die (7) is arranged on the other side of the noseplate (6) and corresponds to the right main shaft (4), a thread passing guide wheel (8) is arranged between the right main shaft (4) and the left main shaft (3), the left main shaft (3) corresponds to a traction wheel combination (9), and the traction wheel combination (9) corresponds to a take-up spool (1).

Description

technical field [0001] The invention relates to a retractable and internally released double-twisting machine. Background technique [0002] The current double-twisting machine adopts the inner take-up type double-twisting machine. Its take-up I-shaped wheel is installed inside the rotating body. The inner take-up is composed of disc spring + friction plate. The extreme difference between the full wheel and the empty wheel is 2.0kgf. During the start-up stage of the machine tool, the take-up tension is unstable, resulting in uneven twisting at the bottom of the wheel; the key process control point, the process parts are located inside the rotating body, and the damage of the process parts cannot be found in time. The product quality is unqualified, affecting the stability of the finished cord. Contents of the invention [0003] The present invention provides a double-twisting machine with external retraction and internal release, which not only avoids the change and fluct...
