Drafting device for spinning

Abstract

The invention relates to the technical field of textile machinery, in particular to a drafting device for spinning, and solves the collection problems that the drafting distance cannot be adjusted, and drafted textile threads cannot be concentrated and knotting prevention cannot be realized existing in a patent of a textile fabric conveying drafting device with the Chinese patent application number of CN201920999293.7. The drafting device comprises a machine body; a winding motor is arranged in the machine body; a lower clamping device is arranged on a second winding shaft; the lower clamping device and an upper clamping device are both movably connected with a yarn roller; the upper clamping device is hinged to an adjusting device; and a drafting mechanism is arranged in the machine body. The yarn roller is clamped through the upper clamping device and the lower clamping device, then the drafting mechanism conducts adjustment according to the needed drafting degree, the spinning yarn is drafted, the drafted spinning yarn drives the adjusting device to move through impurity-removed wind on a processing assembly line, the spinning yarn is spirally wound on the yarn roller, and subsequent knotting is prevented.

Description

technical field [0001] The invention relates to the technical field of textile machinery, in particular to a drafting device for textile. Background technique [0002] Yarn refers to a product processed into a certain fineness from various textile fibers, which can be used for weaving, rope making, thread making and embroidery. Fiber or chemical fiber cut fiber) processed by spinning, divided into ring-spun yarn, open-end spinning, self-twisted yarn, etc.; continuous filament yarn, such as natural silk and chemical fiber filament, divided into twisted or untwisted , smooth filament or deformed filament, etc.; short fiber and continuous filament combined yarn, such as polyester-cotton filament core-spun yarn, etc., are formed by merging and twisting two or more single yarns, and the yarns have Certain elasticity, in the yarn production process, the processed yarn needs to be drafted evenly, so that the yarn can reach the required fineness and strength. The Chinese patent ap...

Problems solved by technology

The Chinese patent application CN201920999293.7 discloses a textile fabric conveying and drafting device. The two sides below the conveying bracket of the utility model are respectively horizontally connected with the feed roller and the discharge roller, and the output end of the draft cylinder is connected with the translation The end of the rack is fixedly connected, and the drafting gear is vertically rotated and connected to the transmission bracket on the upper side of the rotating gear. The transmission bracket outside the drafting gear is fixedly equipped with multiple sets of pulling mechanisms along the radial direction of the drafting gear. The drafting gear A plurality of reciprocating gears are vertically rotated on the outer transmission bracket respectively. The main reciprocating sprocket and the auxiliary reciprocating sprocket are sequentially arranged along the radial direction of the drafting gear. The horizontal rotation is connected to one side of the reciprocating guide plate; the structure design of the invention is reasonable, and it can efficiently and stably continuously draw and process the textile fabric during the transmission process, with a high degree of automation, meeting the needs of processing and use; but the distance of drawing cannot be adjusted, and The textile thread after drafting is not concentrated and prevents the collection of knots
