A multi-ply yarn automatic closing device and its working method

Abstract

The invention discloses an automatic thread closing device for multi-strand yarns, which comprises a yarn supply mechanism, a wetting mechanism, a thread closing mechanism, a thread take-up mechanism and a bobbin support mechanism, the moistening mechanism is located on one side of the yarn supply mechanism, The take-up mechanism is located on the side of the wetting mechanism away from the yarn supply mechanism, a thread closing mechanism is provided between the take-up mechanism and the wetting mechanism, and the bobbin support mechanism is located above the take-up mechanism; the multi-strand yarn The working method of the automatic closing device specifically includes the following steps: Step 1, yarn guiding; Step 2, twisting and closing; Step 3, adjusting the take-up drum; Step 4, starting the equipment for closing. The present invention improves the tensile strength of a single strand of spun yarn by setting a water tank so that the spun yarn passes through the water tank and wets it. When the spun yarn is subjected to a large tension, the tension is converted and decomposed, which reduces the frequent breakage of the spun yarn and improves the production efficiency of the thread.

Description

technical field [0001] The invention belongs to the technical field of textile machinery, and in particular relates to a multi-strand yarn automatic closing device and a working method thereof. Background technique [0002] Ply yarn is generally prepared from two or more strands of filament or spun yarn. When preparing ply yarn, it is necessary to use parallel and twisting equipment. The traditional thread production method is to first use the filament bundle or single yarn with a ring spindle machine or two-for-one twisting machine. The machine performs initial twisting, and then feeds the twisted two or more filament bundles or single yarns into the twisting machine for double twisting processing to obtain two or more finished yarns. This method has low production efficiency. Use different machines to finish in steps; Another way to prepare double-twisted yarn is to use a parallel-twisting machine (one-step twister) to complete primary twisting, paralleling, and double-twi...
