Abstract

The utility model relates to a double-knitting circular knitting machine which is suitable for the two cylindrical fabrics of simultaneous kitting. Two pairs of mutually parallel and concentrical circular shuttle paths for shuttle movement are installed on the machine. An intermediate gearing device is arranged out of the zone of a shuttle opening, which can pushes shuttles to move in the circular shuttle paths. When a rotary table is driven to rotate, the shuttles shuttle between the upper and the lower pairs of circular shuttle paths and reserve between weft yarn and warp to respectively realize the interleaving knitting of the weft yarn and the warp and achieves the purposes of the two cylindrical fabrics of simultaneous knitting.

Description

Circular knitting machine

The utility model relates to a kind of circular loom, is used to produce tubular fabric, is specially adapted to produce simultaneously two tubular fabrics.

Existing circular loom mainly is made up of support, round bottom dish, rotor, shuttle, a pair of annular race.When work, drive rotor, epitrochanterian promotion wheel promotion shuttle along a pair of annular race operation, shuttle shuttles back and forth in the warp thread shed open, and drags down weft yarn, realizes warp thread, and the weft yarn weaving is continuously worked out out tubular fabric.A pair of annular race is only arranged in this circular loom, therefore, can only produce a tubular fabric.

The purpose of this utility model is to overcome above-mentioned weak point of the prior art and proposes a kind of improved circular loom, and it can knit out two tubular fabrics simultaneously.

The purpose of this utility model can reach by following measure: on support, adorn two pairs be parallel to each other, concentric annular race, guiding shuttle in two pairs of annular races, outside the warp thread shed open district between two pairs of annular races, being provided with can be along the intermediate gearing of ring-shaped guide rail operation, promotion wheel on this device contacts with the operation roller of shuttle, follower contacts with epitrochanterian promotion wheel at place, warp thread crosspoint, running roller contact ring-shaped guide rail.

Preferably, form two pairs of annular races by middle footpath 4 circular guideways identical with cross section diameter.

For compact conformation, the following circular guideway of going up annular race can be fixed on the same bone ring with securing member with following last circular guideway to annular race.Used securing member is two hook bolts preferably.

The ring-shaped guide rail that the running roller contacted on the intermediate gearing is following circular guideway and the following last circular guideway of going up annular race to annular race.

The cylindrical minimum point of the follower on the intermediate gearing is lower slightly or identical than the warp thread crosspoint.

Below with reference to accompanying drawings the utility model is described in further detail:

Figure one is the vertical section of doing by the utility model central axial line.

Figure two be among the figure one K to partial enlarged drawing.

Figure three is B-B line profiles among the figure two.

Figure four is a kind of part section enlarged drawings of knitting ring.

Connecting firmly the support＜7〉of hard straight symmetry on the round bottom dish＜10 〉, one can drive rotor rotated＜9〉and is bearing on the round bottom dish＜10 〉, bone ring＜22 〉,＜27 〉,＜31 〉, is packed in support＜7〉inboard, is positioned at rotor＜9〉top.4 circular guideways＜21 〉,＜26 〉,＜28 〉,＜12〉are packed in respectively on bone ring＜22 〉,＜27 〉,＜31 〉, forming two pairs is parallel to each other up and down, concentric annular race is wherein gone up the circular guideway＜26〉to annular race and is descended the circular guideway＜28〉to annular race to be fixed on the middle bone ring＜27〉with securing member.The middle footpath of 4 circular guideways＜21 〉,＜26 〉,＜28 〉,＜12〉and cross section diameter equate.Circular guideway＜26 〉,＜28〉are bolted on the middle bone ring＜27〉with two.

The position that several warp thread are distributed by the warp thread section after deciding what is right and what is wrong is represented in double dot dash line among the figure two.Intermediate gearing is formed by turning frame＜18 〉, follower＜14 〉, running roller＜25〉and promoting wheel＜33 〉, and is between two pairs of annular races outside the warp thread shed open district.Turn frame＜18〉and make with the material with certain intensity, running roller＜25〉contacts with following last circular guideway＜28〉to annular race with last following circular guideway＜26〉to annular race respectively, and intermediate gearing can be moved along it.It is also rotatable that follower＜14〉is contained in the lower end of turning frame＜18 〉, and the cylindrical minimum point of follower＜14〉is lower slightly or identical than the warp thread crosspoint.Turn a pair of promotion wheel＜33〉that is used to promote and limit shuttle＜32〉also is housed on the frame＜18 〉.Bone ring＜22〉is fixed a circular rings＜16〉respectively with the inwall of bone ring＜27〉and is contacted with the motion roller＜34〉of shuttle, is used to prevent that shuttle when static＜32〉from tumbling.A pair of promotion wheel＜13〉is contained in the stand＜11 〉, and can revolve, and stand＜11〉is fixed on the rotor＜9 〉.A pair of promotion wheel＜13〉contact follower＜14〉in the stand＜11〉makes follower＜14〉be in the warp thread crosspoint.A pair of promotion wheel＜34〉also is contained in the stand＜35〉that has been fixed on the rotor＜9 〉.Promoting wheel＜33 〉,＜34〉is in separately the shed open two pairs of shuttles＜32〉in the annular race.If adorn two pairs on the frame＜18〉and promote wheel＜33〉turning, be used for promoting simultaneously respectively and limit with the time down to the shuttle＜32〉of annular race, can remove promotion wheel＜34 〉, and the circular rings＜16〉of bone ring＜27〉inwall is changed the outfit on bone ring＜31〉inwall.

Knit ring＜15 〉,＜19〉and be packed in turning on the frame＜18〉of support＜7〉upper end and intermediate gearing by bearing support＜17 〉,＜20〉respectively.Knit ring＜15〉and can equally make monoblock type, also can be made into ring＜37〉and encircle the form that＜38〉connect by a bearing down with knitting ring＜19 〉.Last ring＜37〉can rotate relatively with following ring＜38 〉.

Comb is packed in the periphery of bone ring＜22 〉,＜27 〉,＜31〉also by up and down annular race being limited to annular race relatively up and down through plate＜24 〉.

Pass through for shuttle＜32〉in order to make warp thread form a shed open, walk around deflecting wheel＜8 〉,＜23〉up and down on each guide palm fibre line＜29 〉.On each guide palm fibre line＜29 〉, each is fixing the equal training for sediment hole＜30〉of two pitch-rows its both sides.In order to actuate guide palm fibre line＜29 〉, the cylindrical of rotor＜9〉is shaped on one and in height is the groove of wavy extension around periphery, is drawing a slide block＜5〉that is enclosed within on the slide bar＜6〉in the groove, and guide palm fibre line＜29〉inboard is fixed on the slide block＜5 〉.Also can adopt one-sided rippled surface guide shoe＜5 〉, at slide block＜5〉first line of a couplet one spring, the spring other end is associated on bone ring＜31〉or the round bottom dish＜10 〉.On jib＜4 〉, tensioning device for warp is housed.Tensioner is made by spring steel wire＜1 〉,＜2 〉, is shaped on the annulus that warp thread passes through on the free end.Be contained on the jib＜4〉through orifice plate＜3 〉, be shaped on the aperture that several pass through for warp thread on it.Position when the warp thread among the figure one represents that slide block＜5〉is in the middle part of rotor＜9〉height.

The utlity model has simple in structurely, easy to manufacture, easy to operate, cost is low, the advantage that floor space is little, efficient is high.
