Description
Technical field
The utility model relates to Computerized flat knitting machine, relates in particular to a kind of shuttle box actuating unit of Computerized flat knitting machine.
Background technology
Guiding such as Fig. 6 of present Computerized flat knitting machine structure and weaving thread.Shuttle box controlling organization 106 is installed on the link 110 of head 104, drives reciprocating motions on needle-bar by head 104, and drives the shuttle box 102 that is positioned at shuttle thick stick 103 both sides and move along the shuttle thick stick.Shuttle box controlling organization 106 required power supply signals conduct to the corresponding power signal input part of this controlling organization by lead, and these leads are placed in the drag chain 109, along with the reciprocating motion of head 104 is dragged back and forth.Be evenly equipped with some take-up framves 100 in the braiding machine upper end, in frame coil holder 101 on one side is set each side, a ball of string 105 that participates in each braiding yarn of braiding is placed on braiding machine rear side or the top, and the end of a thread on it is drawn by a take-up frame 100 of correspondence and all will be guided pairing each shuttle box 102 on the shuttle thick stick into by the sideline frame 101 of frame both sides.
Because there is link 110 head 104 upper ends, makes weaving thread unlikely directly pass head and be incorporated in the corresponding shuttle box 102 from take-up frame 100.Above-mentioned this lead-in wire method, make the braiding yarn several times bending just can be introduced into shuttle box, the pulling force (resistance) that is subjected to when being directed of braiding yarn is big, is easily broken.And each braiding yarn is because 100 distances to sideline frame 101 of pairing take-up are different, and suffered pulling force is also different, and it is unbalanced that each weaves the suffered pulling force of yarn, influences weaving quality.More for a long time, multiple embossing line all will be concentrated by the sideline frame 101 of both sides and introduce as the kind of the required embossing line of braided fabric flower type, easily twines bondingly between the weaving thread mutually, affects the smooth and easy guiding of each weaving thread.
The concern that the problems referred to above have caused more external braiding machine manufacturing enterprises also improves this.Just a kind of Computerized flat knitting machine that directly weaving thread on the take-up frame is guided to shuttle box is arranged abroad at present.Its method that adopts is: do not have link on the head, so that weaving thread directly is directed to shuttle box by the take-up frame, each shuttle box on several shuttle thick sticks is all driven by the motor and the corresponding transmission mechanism of a correspondence.General Computerized flat knitting machine has four shuttle thick sticks, on the every shuttle thick stick several shuttle boxs is arranged all, so whole shuttle box transmission device is very complicated, cost is very high, and it is big to take up room, and makes that the shuttle box quantity on the shuttle thick stick is restricted, thus the design of influence braiding flower shape.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of above-mentioned prior art, for realizing that weaving thread directly is directed to shuttle box from the take-up frame to be adopted: the shuttle box controlling organization placed on the shuttle thick stick drive with this that shuttle box is a kind of like this to carry out the shuttle box actuating unit of a kind of Computerized flat knitting machine of transmission to the shuttle box controlling organization on several shuttle thick sticks, it is implemented by the following technical programs:
Comprise several shuttle thick sticks, several to the master, driven wheel of differential or several to the master, driven spur gear, one power transmission shaft, several synchronously with and the synchromesh gear that is engaged with, several shuttle thick sticks are the fan-shaped arrangement or are arranged in parallel, be provided with a power transmission shaft at shuttle thick stick one end, be equipped with several described drive bevel gear or active spur gear on this power transmission shaft, each shuttle thick stick be provided with synchronizing wheel and with the synchronous band of its engagement, a corresponding drive bevel gear or an initiatively spur gear engagement on described driven wheel of differential of coaxial connection or the driven spur gear in the rotating shaft of a synchronizing wheel, driven wheel of differential on each shuttle thick stick or driven spur gear and power transmission shaft.
One end of described power transmission shaft connects a reducing gear, and power transmission shaft is connected with motor by this reducing gear.
Described several symmetrical center line that is fan-shaped arrangement shuttle thick stick is intersected in a bit on the described Computerized flat knitting machine upper stitch bed center line.
Described shuttle thick stick bottom is provided with for the wound hole of being with cross-under synchronously, moving along its length direction, and two synchronizing wheels are separately fixed at shuttle thick stick two ends, and band passes wound hole and the engagement of this two synchronizing wheel synchronously.
Described synchronous band downside is equipped with a supporting plate, and its upside is equipped with a pressing plate, and the three is linked into an integrated entity by screw or bolt, and pressing plate is connected with the shuttle box controlling organization of shuttle thick stick both sides again.
Described reducing gear is the transmission that a pair of belt pulley and belt are formed.
The beneficial effects of the utility model are: the shuttle box controlling organization that the utility model device has guaranteed originally to be arranged on the head link can be driven after being placed on the shuttle thick stick well.In the utility model device the shuttle thick stick is arranged to fan-shaped and arranges, and make the symmetrical centre of each shuttle thick stick intersect on the needle-bar center line a bit, this has the installation and debugging of being convenient to shuttle box, improves the efficient of braiding machine preparation.The utility model adopts the bevel gear engagement according to the characteristics of shuttle thick stick mounting structure, makes the whole transmission device more compact structure.The utility model provides the structure of power transmission to guarantee from the utility model purpose that the take-up frame directly is directed on the shuttle box weaving thread for realizing.The utility model drives pairing shuttle box controlling organization on each shuttle thick stick, the shuttle box controlling organization drives the shuttle box on this shuttle thick stick according to computer instruction, not only reliable transmission is accurate, and structure is very succinct, make the structure of whole Computerized flat knitting machine simpler, manufacturing cost reduces, and cost performance improves greatly.Simultaneously, because simple to shuttle box driving device, it is little to take up room, and makes the shuttle box on the shuttle thick stick can more placements, can introduce weaving thread more like this, weaves more complicated tissue flower type, makes the knitting property of braiding machine better.
