Yarn continuous twisting device

Abstract

The invention discloses a yarn continuous twisting device and belongs to the weaving processing machinery equipment field. A yarn winding mechanism, a yarn guiding mechanism, a twisting mechanism, a yarn drawing mechanism, and a yarn releasing mechanism of the invention are successively and fixedly arranged on one side of a fixing support from top to bottom. The central section of the lower side of a rotation disc is rotatably connected to a yarn bearing support. A drawing spring is arranged between a yarn drawing pull rod and a yarn wheel support. The upper yarn guide support, the twisting support and the lower yarn guide support of the twisting mechanism are successively, horizontally and fixedly arranged on one side of the fixing support from top to bottom. A reciprocating connection rod is slidably arranged on a reciprocating support along a horizontal direction. A yarn winding roller is horizontally and rotatably connected to a yarn winding support. A yarn winding spring is arranged between a rotation support and the fixing support in an inclined mode. A locking screw rod is arranged between the central section of the upper side of a yarn winding placing rack and the rotationsupport. The structure is designed reasonably, yarns can be high-efficiently and accurately twisted and processed continuously, the twisting degree of the yarns can be increased and a production and usage demand is satisfied.

Description

technical field [0001] The invention belongs to the field of textile processing machinery and equipment, in particular to a yarn continuous twisting device, which is mainly used in yarn twisting processing. Background technique [0002] Yarn is a product processed from various textile fibers into a certain fineness. It is used for weaving, rope making, thread making, knitting and embroidery. There are many types of yarn, which can be divided into staple fiber yarn, continuous filament yarn and Combined yarn, staple fiber is processed by spinning natural staple fiber or chemical fiber cut fiber, divided into ring spun yarn, open-end spinning and self-twisted yarn, etc. Continuous filament includes natural filament and chemical fiber filament, divided into twisted yarn or non-twist, smooth filament or deformed filament, etc., combined yarn refers to the combined yarn of staple fiber and continuous filament, such as polyester-cotton filament core-spun yarn; according to the cla...

[0002] Yarn is a product processed from various textile fibers into a certain fineness. It is used for weaving, rope making, thread making, knitting and embroidery. There are many types of yarn, which can be divided into staple fiber yarn, continuous filament yarn and Combined yarn, staple fiber is processed by spinning natural staple fiber or chemical fiber cut fiber, divided into ring spun yarn, open-end spinning and self-twisted yarn, etc. Continuous filament includes natural filament and chemical fiber filament, divided into twisted yarn or non-twist, smooth filament or deformed filament, etc., combined yarn refers to the combined yarn of staple fiber and continuous filament, such as polyester-cotton filament core-spun yarn; according to the classification of yarn raw materials, it can be divided into pure spinning and Blended yarn, pure spun yarn is a yarn spun from one fiber material, such as cotton yarn, wool yarn, hemp yarn and silk spun yarn, etc. Blended yarn is a yarn spun from two or more fibers, such as Blended yarn of polyester and cotton, blended yarn of wool and viscose, etc.; according to the yarn thickness classification, it can be divided into coarse special yarn, medium special yarn, fine special yarn and extra fine special yarn. Coarse special yarn refers to 32 special yarns. Yarns above and above, medium and special yarns refer to yarns with 21-32 special yarns, fine special yarns refer to yarns with 11-20 special special yarns, and ultra-fine special yarns refer to yarns with 10 special special yarns and below; classified according to the spinning system , can be divided into worsted yarn, slubbed yarn and waste spun yarn. Worsted yarn refers to the yarn spun through the combing process, including combed cotton yarn and combed wool yarn. The fibers in worsted yarn have high parallel straightness. The dryness is even and smooth, but the cost is high and the yarn count is also high. Slubbed yarn refers to the yarn that is carded according to the general spinning system and not spun through the combing process. The short fiber content in the slub yarn is more. Poor parallel straightness of fibers, loose structure and many hairs, low yarn count and poor quality. Waste spinning refers to yarn spun from textile waste cotton or mixed with low-grade raw materials. The quality of the yarn is poor, soft and dry. Uneven, impurity and poor color

Yarn needs to be twisted in the process of production and processing. Twisting refers to the process of winding raw materials such as staple fibers, real silk and chemical fiber filaments into threads. The multiple filaments that make up the yarn must be twisted before they can be intertwined with each other. In order to make the yarn more solid and delicate, the higher the twist, the tighter the yarn is wound. The cloth woven from the yarn is compact, has a good drape and strong fastness. Therefore, in order to increase the strength of the yarn, in the production and processing of the yarn During the process, the twist of the yarn needs to be increased. The existing twisting device for yarn production has a complex structure and troublesome operation. The yarn can only be twisted once, so that the twist of the yarn is relatively low, and it is difficult to increase the twist of the yarn. effect, and the existing twisting device for yarn production is difficult to achieve uniform and efficient winding of the finished yarn bobbin, which makes the yarn loose and fall off during the winding process, resulting in poor quality of the finished yarn bobbin, which cannot meet the production requirements. needs
