Description
Technical field
The present invention relates to the parts that a kind of spinning apparatus is used, particularly a kind ofly be arranged at being used between spinning, drawing device and twisting apparatus and gather the Yarn-collecting device of a fibre bundle.
Background technology
The delivery roller that in traditional spinning apparatus the fiber strip of drawing-off is directly connected to drafting system on twist, during twisting will a so-called spinning triangle appear on the right jaw line of this delivery roller, influence the quality of resultant yarn.This is because the fiber strip of drawing-off leaves drafting system with a fixing width, and co-twisted becomes the cause of the less yarn of diameter.Therefore, be to eliminate the spinning triangle, make fiber in compacting zone by boundling or compacting, thereby make fiber strip when leaving last roll, become very thin, eliminated the spinning triangle, the yarn that is spinned will be more all even solid, and filoplume seldom.
Chinese patent literature CN1936136A discloses improved spinning apparatus, it is provided with a device that is used for compressing fiber assembly between drafting system and twisting apparatus, this device has a pair of output drawing rollers that are positioned at a drafting system to compacting zone afterwards; Have one and transport the conveyer belt of the gas permeability of a fibre bundle through compacting zone thus; Has a suction channel that is arranged in this compacting zone; Have one be arranged on the suction channel, the guiding sliding surface conveyer belt, that be reinforced; Has a suction slit that is arranged in this sliding surface; And have one and on the jaw of the end in this suction slit, this fiber strip is pressed on the conveyer belt and this conveyer belt is pressed on gripping roller on the sliding surface.
This type of device has various, but all can not make the air-flow that enters before the suction channel implement directed to yarn and effectively exert pressure, and consumes unnecessary air-flow above yarn, increases negative pressure, wastes energy.When spinning strand,, cause the winding that is incorporated in of two coring bars easily in addition, produce the yarn of non-strand, influence the quality of strand owing to have two coring bars to feed simultaneously on a conveyer belt.
Summary of the invention
The present invention provides a kind of Yarn-collecting device that closely spins usefulness for addressing the above problem, and makes it can make yarn be directed to airflow direction and prevents that strand from twining.
The present invention solves the problems of the technologies described above the technical scheme that is adopted:
Closely spin the Yarn-collecting device of usefulness, comprise support, poly-yarn plate, support two sides are provided with a pair of projection, and two projections and carriage center are mirror to symmetry, and support is provided with groove and engages with boss on the gear-box, poly-yarn plate top is provided with a pair of catching, and with support on corresponding projection buckle, poly-yarn plate bottom is provided with a pair of leg, is provided with poly-yarn air-flow guiding rib in two legs, poly-yarn air-flow guiding rib height is lower than the height of leg, and difference in height is greater than the thickness of conveyer belt.
Above-mentioned two poly-yarn air-flow guiding ribs can be two or three, to adapt to the different needs that spins and spin strand.
Above-mentioned poly-yarn air-flow guiding rib can be along yarn direction engrail or waveform.
The importing end opening of the middle part yarn of above-mentioned poly-yarn plate bottom is greater than deriving end.
Between the support of above-mentioned Yarn-collecting device and poly-yarn plate flexible member is set also, makes the structure of the two that certain contractility be arranged.
The support and the gear-box of above-mentioned Yarn-collecting device are made one.
The poly-yarn plate of above-mentioned Yarn-collecting device can be made of plastic.
Above-mentioned Yarn-collecting device is arranged in drawing rollers and grips between the roller, the pair of brackets by poly-yarn plate across conveyer belt and flexiblely frame on sliding surface.
Compared with prior art, the invention has the advantages that:
Yarn-collecting device is between drawing rollers and gripping roller, across conveyer belt and flexiblely frame on sliding surface, guiding by the guiding rib on the poly-yarn plate, can make the air-flow that enters before the suction channel implement directed to yarn and effectively exert pressure, above yarn, effectively utilize air-flow, reduce negative pressure, energy savings.
Yarn-collecting device also by the guiding of three air-flow guiding ribs on the poly-yarn plate, makes two coring bars be difficult for merging or twining when spinning strand, improves the quality of strand.
