Description

A kind of small-bore circular knitting machine yarn adding device

Technical field

The invention belongs to textile machine equipment technical field, especially relate to a kind of small-bore circular knitting machine plaiting Device.

Background technology

Circular knitting machine is to utilize the knitting needle being arranged on circular syringe that yarn constitutes coil, then connects through snare Being connected into the knitting machine of cylindrical shape weft-knitted fabric, it is mainly by yarn mechanism, knitting mechanism, tractive-batch Mechanism and drive mechanism composition.Select dissimilar and bore syringe, can produce for industrial or agricultural with And the fabric tube of biomedical sector, the most small-bore circular knitting machine can be used to prepare medical human Tubular bracket, intestinal stent as described in Chinese invention patent (publication number: CN103705325A), The braiding of small-bore circular knitting machine is all used to form.

Multi-level Organization Structure (such as epidermal area, muscle layer and internal layer etc.) and pipe in view of human body self pipeline Many layer functions (medicament slow release layer, degradable material layer and organizational project composite bed) of shape support, Ke Yitong Cross introducing yarn adding device and simulate the bionical medical tubular rack with multiple structure.Plating structure also known as " lid hair tissue " and " interlaced structure ", be simultaneously to knitting by two or more different yarn Pincushion yarn, makes the positive and negative of fabric form different colours and the coil of different-style.Plating structure extensively should In the various coil tissues of the fabric woven by circular knitting machine, when circular knitting machine weaves, it is desirable to veil phase The Feeding point of knitting needle and vertical angle are respectively less than to the pad yarn transverse and longitudinal angle of filling, in order to knitting needle hooks up simultaneously Veil and filling, after being inverted lopping, veil is inverted the front being presented on fabric, and filling is inverted It is presented on the reverse side of fabric.Owing to plating structure veil coil overlaps above ground yarn coil all the time, because of And when weaving, knitting needle, yarn guide, yarn tension, plaiting angle are had particular/special requirement, its technological requirement The highest, the improper coverage effect that can affect two or more coils of parameter designing, thus impact is knitted The outward appearance of thing.

Existing yarn adding device structure is complicated, and cost of manufacture is high, installs and keeps in repair trouble, being not easily adjustable Technological parameter.The yarn adding device using override interrupt can only the most effectively feed an one thread, or simultaneously In a guide eyelit, feed two one threads, but two one threads are the most mutually wound around, it is impossible to realize multilamellar Braiding structure requirement, and yarn tension cannot the problem such as on-line measurement and regulation, as Chinese patent is (public The number of opening: CN204589494 U) described in adding set.Therefore, invention one is for small-bore round latitude The yarn adding device with weft tensioner of machine, significant.

Summary of the invention

The present invention seeks to: provide one to be not only simple in structure, and lapping position and angle can be realized Adjustable, it is simultaneously introduced threads (wire gauze and veil), requires with satisfied different plaited fabrics braidings Small-bore circular knitting machine yarn adding device.

The technical scheme is that a kind of small-bore circular knitting machine yarn adding device, including being fixed on syringe work Make the support bar on face, be located at the arrangement for adjusting height of described supporting bar top, fill with described altitude mixture control Put the rotation adjustment device of connection, and the plaiting lever jack being connected with described rotation adjustment device;Institute State and plaiting yarn guiding assembly is installed on plaiting lever jack;Described plaiting yarn guiding assembly adds described in including being installed on At least one guide tripod of yarn lever jack upper surface, and be connected with described plaiting lever jack end Yarn-guiding mouth;Head end at described Yarn-guiding mouth is provided with the guide eyelit that several are arranged in parallel, can be simultaneously introduced Many different wire gauzes and veil, can meet the braiding requirement of different plaited fabrics.

As preferred technical scheme, described arrangement for adjusting height includes about two teeth engaging setting Wheel;Described rotation adjustment device includes pivoting lever, and is used for connecting described pivoting lever and institute State the rotating adjusting nut of plaiting lever jack;And gear above is solid with described pivoting lever top Fixed connection, by regulating the tooth matching angle of two gears, adjusts height and the angle of Yarn-guiding mouth.

As preferred technical scheme, described rotation adjustment device includes that be set on described support bar turns Dynamic pair, described arrangement for adjusting height includes the set screw being installed in described revolute pair, described revolute pair It is connected with described plaiting lever jack by moving sets.

As preferred technical scheme, on described plaiting lever jack, it is positioned at described guide tripod and institute State and yarn tension controller is installed between rotation adjustment device, measure in real time and the merit of regulation plaiting tension force Energy.

As preferred technical scheme, described guide tripod is provided with two symmetrically arranged guide eyes, And hole, location is installed in the middle part of described guide tripod and is positioned at the pin in hole, described location, described Bottom plaiting lever jack, it is positioned at described pin bottom and is provided with fixing nut.

As preferred technical scheme, described support bar bottom is fixed on described syringe work surface by nut On.

As preferred technical scheme, described Yarn-guiding mouth is internal uses hollow structure.

The invention have the advantage that

1. the present invention is not only simple in structure, operates simply, controls to stablize, and can realize padding yarn position Put and adjustable angle, be simultaneously introduced threads (wire gauze and veil), compile with satisfied different plaited fabrics Knit requirement, applied widely, it is simple to large-scale production and application;

2. the present invention possesses real-time online measuring and regulation yarn tension, and automation degree of equipment improves, Adapt to the requirement of difference braiding speed;
