Description
Technical field
It the utility model is related to a kind of drive device of the weft yarn needle plate of cloche.
Background technology
Cloche is that warp thread and weft yarn are first woven into warp knit inlaid thread tissue " cloth ", then cloth is cut into one by blade
Rule yarn (cutting weft yarn).Or the tape yams of warp knit inlaid thread tissue are directly woven into warp thread and weft yarn.Crocheting fancy
Yarn is characterized in warp thread continuous-loop, and weft yarn pads, and resultant yarn is into flat.
The weft yarns of common cloche are to drive weft yarn to realize by the weft yarn needle on weft yarn needle plate.Latitude
Yarn pin is a kind of device for being fixedly mounted on and being used for guiding weft yarn to complete braid movement on weft yarn needle plate.During the head of weft yarn needle is
Between hollow tube, weft yarn with the motion of weft yarn needle from top to bottom through moving after the conduit of weft yarn needle section.
The motion of weft yarn needle plate can be divided into vertically to be carried out simultaneously with two kinds of left right horizontal movement, the two motions,
It is exactly that weft yarn needle will also move horizontally while rising or decline.Weft yarn needle plate the right and left is pacified installed in weft yarn needle plate
Fill on seat, be eccentric wheel below weft yarn needle plate mounting seat, the up and down motion of weft yarn needle plate is to drive weft yarn needle plate peace by eccentric wheel
Dress seat moves up and down to realize；Weft yarn needle plate can also move left and right in weft yarn needle plate mounting seat simultaneously, weft yarn needle plate
Horizontal movement is driven by the card on card wheel, and card guide bracket is then for by card number size (i.e. the height of card)
It is transformed into the direction displacement of weft yarn needle plate level, high point and the left and right displacement of the more big then weft yarn needle plate of the difference in height of low spot on card wheel
Also it is bigger.Card guide bracket simultaneously can also be by displacement equations certain multiple.Card number and the length adjustment of weft yarn needle displacement can
Realized by the fixing screws on mobile card guide bracket, higher then multiplication factor is bigger.The left and right positioning of weft yarn needle can be by even
Bar adjusts.
For common yarn, warp thread swings same in continuously lopping, weft yarn under the drive of weft yarn needle
When fixed by the warp thread institute resultant yarn circle of left and right two, then weft yarn by centre blade be divided into two, weft yarn in warp thread circle only
It is to be enclosed around one, the fixation fastness of weft yarn and warp thread is not fine, and the depilation of weft yarn is easily caused during use.
Utility model content
Technical problem to be solved in the utility model is：A kind of cloche that can make weft yarn fixation in resultant yarn is provided
Weft yarn needle plate drive device.
In order to solve the above technical problems, technical scheme is used by the utility model：The drive of the weft yarn needle plate of cloche
Dynamic device, including the horizontal drive shaft that is rotatably arranged in frame and it is arranged on being rotated around horizontal axis in frame
Rotation seat, the rotary centerline and drive shaft of rotation seat are perpendicular；Fixed cover is provided with eccentric wheel in drive shaft, and eccentric wheel periphery leads to
Cross bearing and be connected with retainer, movable be equipped with passes transmission parallel to the mounting seat for driving direction of principal axis, mounting seat in retainer
One end of seat is provided with weft yarn needle plate, and the other end that mounting seat passes retainer is hinged with connecting rod；Cam is set on rotation seat, in frame
Card guide bracket is hinged with, card guide bracket one end is in contact with cam periphery, and interlinking lever end is hinged with card guide bracket the other end,
At card guide bracket and cam contact, with frame hinged place, with 3 line triangular shapes at rod hinge connection；Cam periphery is divided into
Three sections driving curved sections, every section driving curved sections include set gradually the first low spot for making weft yarn needle be located on the left of left warp,
Make the first middle part point that weft yarn needle is located on the right side of left warp, make the second low spot that weft yarn needle is located on the left of left warp, make weft yarn needle
The first high point on the right side of right warp, make the second middle part point that weft yarn needle is located on the left of right warp, weft yarn needle is located at right warp
The second high point on the right side of line, the 3rd low spot for making weft yarn needle be located on the left of left warp.
As a kind of preferable scheme, the pin joint of the card guide bracket and frame is located at driving member and cam contact
Lower section.
As a kind of preferable scheme, the card guide bracket is provided with the roller being in contact with cam periphery.
The beneficial effects of the utility model are：Because cam periphery is divided into three sections of driving curved sections, every section of driving curved sections
Including making of setting gradually the first low spot that weft yarn needle is located on the left of left warp, make that weft yarn needle is located on the right side of left warp first in
Portion's point, make the second low spot that weft yarn needle is located on the left of left warp, make the first high point that weft yarn needle is located on the right side of right warp, make weft yarn
Pin is located at the second middle part point on the left of right warp, makes the second high point that weft yarn needle is located on the right side of right warp, makes weft yarn needle positioned at a left side
The 3rd low spot on the left of warp；So that the motion of weft yarn needle plate is changed into being repeated once the dynamic of braiding the warp yarn position of left and right two more
Make so that weft yarn is in warp thread circle by around a circle, this allows for weft yarn and is fixed by warp thread circle more firm, and this is just more
Solve the problems, such as that the weft yarn in fluffy yarn easily loses hair or feathers well.And driving curved surface make it that transition is more smooth, transmission is more
Add steadily, noise is also smaller.
Because the driving member is provided with the roller that is in contact with cam periphery so that the motion of driving member it is more smoothly and
Greatly reduce the abrasion between card guide bracket and cam.
