Technical field
The present invention relates to Computerized flat knitting machine technical field, specifically a kind of knitted fabric draw-off mechanism of Computerized flat knitting machine.
Background technology
As everyone knows, draw-off mechanism is to complete braiding process smoothly, and the coil in pin ditch must be avoided to rise along with the rising of pointer, otherwise just can not realize moving back circle, and namely old coil can not slip down to below needle latch, also just can not form new coil.The coil taken off to prevent syringe needle obstructs weaving and completes smoothly, this coil must be pulled to needle back, in time established fabric pull-out knitting zone.
In prior art, illustrate and thatly carry out tractive fabric by the clamping of major-minor two pairs of pulling roll and the rotation of roll shaft, fabric length between knitting zone and draw-off mechanism keeps constant, the design of complex pattern just has limitation, product category is naturally restricted, and mechanism can obtain a constant downward pulling force.The kind of drive traditionally, pulling roll can obtain a unidirectional pulling force when the traversing one end to needle-bar of head.

Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described in further detail:
As the embodiment of the knitted fabric draw-off mechanism of Computerized flat knitting machine of the present invention, as Fig. 1, Fig. 2, shown in Fig. 3 and Fig. 4, comprise front needle-bar 1, rear needle-bar 2, first main tractive roll shaft 3, second main tractive roll shaft 4, 3rd main tractive roll shaft 5 and tractive comb 6, described front needle-bar 1 and described rear needle-bar 2 are in falling the setting of " V " shape, gap 7 is provided with between the upper end of described front needle-bar 1 and described rear needle-bar 2, the below in described gap 7 is provided with the main pulling roll 8 in left side and the main pulling roll 9 in right side, the main pulling roll 9 of the main pulling roll in described left side 8 and right side is symmetrical arranged, described first main tractive roll shaft 3, second main tractive roll shaft 4 and the 3rd main tractive roll shaft 5 to be located in equilateral triangle below the main pulling roll of the main pulling roll in described left side 8 and right side 9 and between described front needle-bar 1 and rear needle-bar 2, described first main tractive roll shaft 3 is located at left side, described second main tractive roll shaft 4 and the 3rd main tractive roll shaft 5 are located at right side, described second main tractive roll shaft 4 is positioned at above described 3rd main tractive roll shaft 5, described first main tractive roll shaft 3, be not in contact with each other between second main tractive roll shaft 4 and the 3rd main tractive roll shaft 5, described tractive comb 6 to be located between described front needle-bar 1 and rear needle-bar 2 and to be positioned at the below of described 3rd main tractive roll shaft 5.
In the present embodiment, the lateral wall of the described first main tractive roll shaft 4 of main tractive roll shaft 3, second and the 3rd main tractive roll shaft 5 is provided with round-arced tooth 10.
In the present embodiment, described first main tractive roll shaft 3 is provided with electromagnetic valve 11.
In the present embodiment, described tractive comb 6 has been provided with end pin 12, and at the bottom of described, pin 6 has been provided with end needle guard 13.
In the present embodiment, the cross section shape triangular in shape of the main pulling roll of the main pulling roll in described left side 8 and right side 9.
Operation principle is as follows: head motion, and described front needle-bar 1 and rear needle-bar 2 just take up one's knitting, and when originally weaving refuse yarn, tractive comb 6 chief editor knits refuse yarn, draws the more tractive comb that leans on and draw effect 6 times under refuse yarn.Now the first main tractive roll shaft 3 is in left station, weave in the process of two row yarns 14 at knitting mechanism, tractive comb 6 by chain gear transmission, starts rising and is in and waits to hook line states, when after two row of casting off, head is parked in machine high order end and waits for that tractive comb 6 hook gets yarn 14.Tractive is combed after 6 rising hooks get yarn 14, plays end pin 12 and closes.Then, tractive comb 6 drops to security bit, and head is by programme-control, and operate braiding voluntarily that start below.
No matter whether comb 6 tractive refuse yarns with tractive, when yarn 14 is knitted to a certain extent, tractive task is just responsible for primarily of the main pulling roll 9 of the main pulling roll in left side 8 and right side.Torque motor provides power, allows the main pulling roll 8 in left side and the main pulling roll 9 in right side coordinate knitting mechanism to carry out tractive.In essence, the main pulling roll 8 in left side is relevant with the rotating speed of himself with the traction force of the main pulling roll in right side 9, namely the effect of draw-off mechanism is mainly reflected on the rotating speed of the main pulling roll 8 in left side and the main pulling roll 9 in right side, and it is crucial that tractive comb 6 coordinates with the speed of knitting mechanism.
After knitting mechanism completes a line coil, draw-off mechanism can be continuously, carry out in time, it can leave behind by the main pulling roll 8 in left side and the main pulling roll 9 in right side fast, the yarn 14 woven can be strained rapidly, and the traction force acting on each wale should keep stablizing, evenly and consistent.
In braiding process, if knitting mechanism braiding is the general fabric organized, pin as flat in latitude, rib-loop, double ribs etc. do not need the tissue turning over pin, then the cooperation of tractive comb 6 and knitting mechanism is just fairly simple, mainly in action, head runs back and forth and coordinates knitting needle to weave, now for the main pulling roll 8 in left side and the main pulling roll 9 in right side, the main moment regulating main tractive motor according to braiding speed, and then change the traction force of the main pulling roll 8 in left side and the main pulling roll 9 in right side.
In braiding process, if knitting mechanism braiding is the fabric of more complicated, as repeatedly tuck, local braiding, widening etc. need the tissue turning over pin, then the first main tractive roll shaft 4 of main tractive roll shaft 3, second and the 3rd main tractive roll shaft 5 coordinated knitting mechanism, first main tractive roll shaft 3 is controlled to be in right working position by electromagnetic valve 11, provides suitable traction force.At this time the first main tractive roll shaft 4 of main tractive roll shaft 3, second and the 3rd main tractive roll shaft 5 will play main traction action, and three does not contact each other, produce not too large extruding draw to fabric; The first main tractive roll shaft 4 of main tractive roll shaft 3, second and the 3rd main tractive roll shaft 5 are responsible for the tension force of adjustment tractive, and the tractive take-up quantities in the unit interval can regulate as required, and can adjust under the state of machine run.
If braiding is fast and traction force is little, just there will be needle-bar hole and tractive comb between accumulate pieces of cloth, cause pulling force inadequate and make the coil traction force that weaving less or without traction force.If traction force is excessive, braiding speed does not catch up with draw rate, then knitting needle can be made impaired.If knitting needle turns over pin action, then the traction force turning over pin section tractive comb is suitably little, because like this coil pine is convenient to the transfer of coil, is unlikelyly damaged by yarn 14 or loses knitting needle.
If fabric is due to accident, suddenly around on the first main tractive roll shaft 4 of main tractive roll shaft 3, second and the 3rd main tractive roll shaft 5, the main pulling roll 9 of the main pulling roll in left side 8 and right side realizes being rotated counterclockwise, and upwards loose cloth, makes spooler reverse with relaxed fabric chucking power.
