Description
Technical field
The present invention relates to the computer flat knitting machine field, relate in particular to a kind of braiding controlling mechanism of computer flat knitting machine.
Background technology
The braiding controlling mechanism of computer flat knitting machine is arranged on the cam base plate, generally is made up of single or multiple system for weaving.Below be two kinds of braiding controlling mechanisms of now using type.
Fig. 1 is the braiding controlling mechanism setting that two system for weaving are formed.This braiding controlling mechanism is set to two system for weaving, can be single or two system for weaving participate in braiding simultaneously.Elevating cam 102 and transfer cam 101 are to implement one on the other interlock mode with the form of lever with solenoid actuated.During lopping, elevating cam 102 puts down, and transfer cam 101 is mentioned, and 111 times pin heels of 102 pairs of needle jacks of elevating cam effect makes knitting needle enter lopping work.During barring-on, the triangle action is then opposite, and transfer cam 101 puts down, and to needle jack 111 top butt effects, elevating cam 102 is mentioned, and makes knitting needle enter barring-on and receiving coil work.Barring-on, adapter ring (connecing pin), tuck knitting are also wanted the cooperation of push jack group 107.The push jack group works to 113 station pins (spring needle), 107 is movable push jack group, 108 do not weave pressing plate, make push jack in A, H, three positions of B, the action of push jack group is by a plurality of solenoid actuated, and structure is too complicated, the size of cam base plate is bigger, so that the also corresponding increase of head of cam base plate is installed, causes head revolution in coming and going operation process to reduce braid efficiency apart from excessive at last.
Fig. 2 is the braiding controlling mechanism setting of single system for weaving.Have general knitting property, but do not possess the minute hand function.Among the figure: left rise cam 201, right rise cam 202, elevating cam 203 and transfer cam 204, be perpendicular to the cam base plate action, also drive by electromagnet 205, see Fig. 3, therefore, the front and back cam base plate has 8 electromagnet actions of 8 vertically-acting trigonometric sums.Too much movable triangle and the action of too much electromagnet cause the physical fault rate higher.
Summary of the invention
The objective of the invention is the above-mentioned defective at prior art, the braiding controlling mechanism of the computer flat knitting machine that a kind of compact conformation is brief, bolt cam is few is provided.
For solving the above-mentioned defective of prior art, the technical scheme that the present invention will solve is: a kind of braiding controlling mechanism of computer flat knitting machine, comprise cam base plate, described cam base plate is provided with at least one braiding unit, and described braiding unit comprises that a plurality of needle selection devices, needle selecting cam, selection piece that whether the control knitting needle the is in woven condition trigonometric sum selection piece that resets lifts the pin triangle; The density triangular of control knitting needle action, transfer cam, barring-on track triangle, withdrawal of needle is endured the pin Composite Triangular, connect pin tuck Composite Triangular, the adjustable back stitching triangle of last back stitching trigonometric sum, described density triangular, transfer cam, barring-on track triangle, last back stitching triangle, adjustable back stitching triangle is arranged on the top of described cam base plate, the described selection piece triangle that resets is arranged on the centre of described cam base plate, described needle selecting cam, connect pin tuck Composite Triangular and selection piece and lift the bottom that the pin triangle is arranged on described cam base plate, described needle selection device is arranged on the reset centre of triangle of described needle selecting cam and selection piece, and described withdrawal of needle is endured the pin Composite Triangular and is connected by a linkage with described transfer cam.
A kind of improvement as the braiding controlling mechanism of computer flat knitting machine of the present invention, described linkage comprises a pair of shaft step motor, one of them output axle head of described twin shaft stepper motor is provided with first lifter cam, another output axle head of described twin shaft stepper motor is provided with second lifter cam, the end of described first lifter cam is provided with transfer cam lifting guide pillar body, described transfer cam lifting guide pillar body is connected with described transfer cam, the end of described second lifter cam is provided with withdrawal of needle and endures pin Composite Triangular lifting guide pillar body, described withdrawal of needle is endured pin Composite Triangular lifting guide pillar body and is endured the pin Composite Triangular with described withdrawal of needle and be connected, and the link of described twin shaft stepper motor and described second lifter cam is provided with sensing sheet and sensor.
As a kind of improvement of the braiding controlling mechanism of computer flat knitting machine of the present invention, described density triangular loose joint and described cam base plate upper end, and by second step motor control.Braiding wants the stitch tightness of cellulose fabric to be implemented by density triangular, and the density triangular loose joint is in cam base plate, and each advances Electric Machine Control by one one left and right sides density triangular, and sliding along cam base plate splayed skewed slot is divided into a plurality of density ranks by fabric coil density requirements.
Compared with prior art, advantage of the present invention is: the present invention adopts all kinds of triangles to form the woven extent of a compactness through distribution rationally on cam base plate; In the braiding process, density triangular is parallel movement with cam base plate; Withdrawal of needle is endured the pin Composite Triangular and is controlled relative interlock with transfer cam by a linkage, makes vertically-acting with cam base plate, and all the other triangles are all fixed with cam base plate.Compact conformation of the present invention is brief, bolt cam is few, and it is strong to use stepper motor to drive the triangle reliable in action, reduces fault rate, cheap and good knitting property with branch needle knitting function etc.; And various push jacks and compressing tablet in the former computer flat knitting machine have been saved, simultaneously owing to movable triangle reduces in a large number, remove numerous unnecessary electromagnet, only implemented interlock control braiding, barring-on, connect actions such as pin and tuck with a stepper motor, reduced failure rate of machinery to greatest extent.
