Detailed Description
To further clarify the objects, features and functions of the present invention, a preferred embodiment will be described in detail below with reference to the accompanying drawings, in which:
please refer to fig. 1, which is a schematic structural diagram of a preferred embodiment of the present invention, the present invention is a virtual line pressing structure of a needle plate of a flat knitting machine, mainly comprising a sinker 1, a tooth mouth piece 2 and a needle bed 3, wherein the tooth mouth piece 2 is located at an end of the needle bed 3, a fixed bottom plate 4 is arranged above the needle bed 3, a movable plate 5 is arranged above the bottom plate 4, the movable plate 5 is driven by a sinker assembly and pushes the sinker 1 to translate, after the sinker 1 translates to a certain position, the sinker 1 rotates to press a stitch, so that the front end of the sinker 1 is located above the tooth mouth piece 2 before pressing the stitch, thereby pressing the stitch or the long virtual line better, wherein, the rotation of the sinker 1 is also driven by the sinker assembly.
As shown in fig. 3 and 4, the letter-gram assembly comprises a letter-gram bottom plate 6, a letter-gram push plate 7 and a push row 8, wherein one side of the push row 8 is toothed and is linked with the motor through a screw rod. Push away row 8 and believe gram push pedal 7 and be connected and with the motor linkage, be equipped with at least a set of spout in the letter gram push pedal 7, still including being located 6 sides of letter gram bottom plate and corresponding at least two sets of activity triangles of a set of spout, the activity triangle comprises sinker triangle 11, the corresponding movable plate triangle 51 that promotes movable plate 5 that corresponds promotion sinker 1. Wherein, sinker triangle 11, activity piece triangle 51 are equipped with respectively and run through letter gram bottom plate 6 pulley holder 61, and all have the pulley to be located the spout that corresponds in the pulley holder 61, and when pushing away row 8 and promoting letter gram push pedal 7 horizontal migration, the shape of spout forces pulley holder 61 up-and-down motion, and accessible pulley drive sinker triangle 11 does not synchronous translational motion with activity piece triangle 51.
Specifically, the chute is composed of a first chute 71 and a second chute 72 which are sequentially arranged from top to bottom, and the left and right sides of the two chutes are provided with slopes to move upwards and then extend towards the two sides in a translation manner; wherein, the pulley corresponding to the sinker cam 11 is positioned in the first chute 71, and the pulley corresponding to the movable sinker cam 51 is positioned in the second chute 72. Namely, when the Xinke push plate 7 translates left and right, the movable triangle at the translation end performs opening motion, and the movable triangle at the other end performs resetting closing motion.
In order to ensure that the two processes are uniformly realized by the same set of movable triangles, the method comprises the following steps: when the two groups of movable cams are positioned in the middle of the sliding grooves, the distance between the pulley of the movable cam 51 and the slope of the second sliding groove 72 is shorter than the distance between the pulley of the sinker cam 11 and the slope of the first sliding groove 71, so that the movable cam 51 can be ensured to act in advance, the movable plate 5 pushes the sinker 1 to move forwards, and then the sinker cam 11 acts to rotate the sinker 1; the length of the upward slope of the first sliding groove 71 is greater than that of the second sliding groove 72, so that the pushing stroke of the sinker cam 41 is greater than that of the movable sinker cam 42, the sinker has a sufficient rotation angle, and the coil or the long dotted line is pressed.
The sensor 81 is fixedly connected to the push bar 8, and can sense the horizontal translation distance of the push bar 8 and the zero return state of the push bar 8, so that the opening or resetting process of the movable triangle is ensured to be complete.
As shown in fig. 2, the movable plate 5 has a groove, and the bottom of the sinker 1 rotates and moves in the groove, and in order to ensure smooth rotation of the sinker 1, the groove of the movable plate 5 is preferably a semicircular groove. When the knitting needle retreats from the ring, the movable plate cam 51 pushes the movable plate 5 to move forward, and after the movable plate 5 moves forward to the position, the sinker cam 11 drives the sinker 1 to rotate towards the tooth mouth piece 2 to press the coil.
A plurality of parallel inserting pieces 9 are uniformly distributed on the needle bed 3, and a bottom piece 4, a movable piece 5 and a sinker 1 are uniformly distributed in a gap between every two inserting pieces 9, because every inserting piece 9 and the bottom piece 4 need to be fixedly arranged, every inserting piece 9 and the bottom piece 4 are connected in series by steel wires, and every inserting piece 9 is fixed in a groove of the needle bed 3 side by side.
It should be understood that the above-described embodiments are merely exemplary of the present invention, and not restrictive, since various changes may be made therein without departing from the spirit and scope of the invention.
