A kind of wire-threading device
Technical field
The present invention relates to a kind of wire-threading device, particularly relate to a kind of wire-threading device on sewing machine.
Background technology
In Weaving device, wire-threading device right and wrong are usually shown in, during the use of the needlework of sewing machine, the elasticity of needlework self is moderate, and the needlework of pine excessively are easily wound around and knotting phenomenon occurs together, and the yarn of tension easily occurs that stress is concentrated simultaneously, there is broken string phenomenon, therefore, have employed wire-threading device to reduce by two kinds of phenomenons, utilize the elasticity of wire-threading device regulation yarn self.But existing wire-threading device mostly uses and carries out line ball and the regulation of needlework elasticity by spring, if utilizing spring to carry out line ball, its line ball both sides discontinuity causes line ball unstable, easily produce during the use of sewing machine and loosen, thus the phenomenon that needlework are tied a knot occurs, have impact on the production efficiency of sewing machine.
Summary of the invention
For the technical problem of above-mentioned existence, it is an object of the invention to: propose a kind of line ball stable, needlework are difficult to loosen and produce the wire-threading device of knotting.
The technical solution of the present invention is achieved in that a kind of wire-threading device, including support, platen, connecting plate, locating dowel, tabletting, pressure ring block, threading axle and cylinder;Described frame bottom is provided with platen;It is provided with connecting plate below described platen;Described platen is provided with multiple locating dowel;Connect in described locating dowel and have tabletting;Described tabletting is arranged over pressure ring block;It is provided with threading axle between described pressure ring block and tabletting;Described pressure ring block and tabletting all can move along the length direction of threading axle;Described threading axle is provided with the first through wires hole;Described pressure ring block is connected above cylinder;Described cylinder is fixed on support.
Preferably, the described locating dowel left and right sides is additionally provided with eyelet strip;Described eyelet strip is fixed on platen;The second through wires hole is set on described eyelet strip;On described first through wires hole and the second same axial line in through wires hole position.
Preferably, described platen is additionally provided with multiple wire-wrap board;Described wire-wrap board is provided with winding bore;Described wire-wrap board is positioned at locating dowel side.
Due to the utilization of technique scheme, the present invention compared with prior art has the advantage that
A kind of wire-threading device of the present invention program, by utilizing cylinder that pressure ring block is moved up and down, thus needlework being pressed between pressure ring block and tabletting steadily, pressing action is carried out owing to using cylinder, like this its pressure applies equilibrium steadily, needlework are not likely to produce loosening fixing time, it is to avoid the generation of needlework knotting phenomenons.

Detailed description of the invention
The present invention is described below in conjunction with the accompanying drawings.
Of the present invention a kind of wire-threading device as illustrated in the accompanying drawings from 1 to 3, including support 1, platen 13, connecting plate 2, locating dowel 3, tabletting 4, pressure ring block 5, threading axle 6 and cylinder 8;It is provided with platen 13 bottom described support 1;It is provided with connecting plate 2 below described platen 13;Described platen 13 is provided with multiple locating dowel 3;Connect in described locating dowel 3 and have tabletting 4;Described tabletting 4 is arranged over pressure ring block 5;It is provided with threading axle 6 between described pressure ring block 5 and tabletting 4;Described pressure ring block 5 and tabletting 4 all can move along the length direction of threading axle 6;Described threading axle 6 is provided with the first through wires hole 7;Described pressure ring block 5 is connected above cylinder 8;Described cylinder 8 is fixed on support 1;Described locating dowel 3 left and right sides is additionally provided with eyelet strip 9;Described eyelet strip 9 is fixed on support 1;The second through wires hole 10 is set on described eyelet strip 9;On described first through wires hole 7 and 10 same axial lines of the second through wires hole;Multiple wire-wrap board 11 it is additionally provided with on described support 1;Described wire-wrap board 11 is provided with winding bore 12;Described wire-wrap board 11 is positioned at locating dowel 3 side.
Of the present invention a kind of wire-threading device as illustrated in the accompanying drawings from 1 to 3, before beginning to use, first pass through connecting plate wire-threading device is fixed on the board of sewing machine, then needlework first pass through the winding bore on wire-wrap board, the second through wires hole being subsequently passed through on eyelet strip, then pass through the first through wires hole on threading axle, last again through the second through wires hole on eyelet strip, so when sewing machine is started working, cylinder is opened, the expansion link of cylinder drives and moves under pressure ring block, thus the needlework in the first through wires hole are pressed in tabletting and pressure ring block, pressurized is carried out owing to it uses cylinder, cylinder pressure applies equalization stable, so that needlework compress balance, needlework are difficult to loosen the phenomenon producing knotting.
The wire-threading device of the present invention, it is simple to operate, needlework Compression Stability, and needlework are difficult to loosen thus produce knotting phenomenon, it is ensured that the normal work that sewing machine produces.
Above-described embodiment is only for technology design and the feature of the explanation present invention; its object is to allow person skilled in the art will appreciate that present disclosure and to be carried out; can not limit the scope of the invention with this; all equivalence changes made according to spirit of the invention or modification, all should contain within the scope of the present invention.
