Description

Technical Field

[0001] The present invention relates to a bottom plate of a flat knitting machine in the technical field of flat knitting machines, and particularly to a bottom plate device for seven-station same-row hanging eye, which belongs to a key component and its execution method in flat knitting machines. Background Art

[0002] The performance of the bottom plate in a flat knitting machine will directly affect the knitting function of the flat knitting machine. The existing design of the same-row hanging eye structure of the flat knitting machine bottom plate is not reasonable enough. Currently, the same-row hanging eye bottom plate uses the same-row hanging eye triangle to replace the knitting triangle to perform the knitting action, and uses the selector blade to push the knitting needle to move. The bottom plate has a greater load, greatly increasing the working time of the selector blade, affecting the service life of the machine, and affecting the knitting function of the flat knitting machine. Summary of the Invention

[0003] In order to solve the above technical problems, the main object of the present invention is to provide a bottom plate device and its execution method for a direct selector flat knitting machine with a more reasonable structure and more stable operation.

[0004] In order to achieve the above object, the technical solution adopted by the present invention is as follows:

[0005] A bottom plate device includes a same-row hanging eye bottom plate structure and a seven-station control structure; the seven-station control structure includes a driving motor, an upper cam, a signal disk, a lower cam, and a needle lifting triangle cam, and one driving motor simultaneously controls the rotation of the upper cam, the signal disk, the lower cam, and the needle lifting triangle cam.

[0006] Further, the bottom plate device is characterized in that the same-row hanging eye bottom plate structure includes a purl triangle, a knitting triangle, a left needle casting-on triangle, a right needle casting-on triangle, a left stitch receiving triangle, a right stitch receiving triangle, an anti-knit center triangle, and a needle lifting triangle. The above triangles can protrude and retract into the same-row hanging eye bottom plate structure under the control of the seven-station control structure, so that multiple different triangles contact the knitting needles and selector blades to complete different knitting actions.

[0007] Further, the bottom plate device is characterized in that the seven-station control structure controls the triangles to complete seven instructions: knitting, same-row hanging eye with knitting, purling, hanging eye, leftward movement with right stitch receiving, rightward movement with left stitch receiving, and idle running.

[0008] Further, the bottom plate device is characterized in that each instruction corresponds to a position on the signal disk.

[0009] Further, the bottom plate device is characterized in that the signal disk determines the currently executed instruction by sensing the rotation angle of the driving motor through an encoder.

[0010] Furthermore, the bottom plate device is characterized in that when the triangle protrudes from the bottom plate structure of the same-row hanging eye, the triangle contacts the knitting needle or the needle selecting piece, so that the knitting needle or the needle selecting piece moves along the outer contour of the triangle to form different needle moving trajectories.

[0011] Furthermore, the bottom plate device is characterized in that the seven-station control structure forms a digital signal through an encoder for the angle of rotation of the driving motor by means of a signal disk and feeds it back to the bottom plate control system.

[0012] Furthermore, the bottom plate device is characterized in that the above-mentioned triangle is movably embedded in the bottom plate structure of the same-row hanging eye.

[0013] Furthermore, the bottom plate device is characterized in that guide posts are provided on the back of the above-mentioned triangle, a lifting seat is installed on the guide posts, a bearing is installed on the lifting seat, a triangle fixing plate is installed at the end of the guide posts, and a return spring is sleeved between the lifting seat and the triangle fixing plate.

[0014] Furthermore, the bottom plate device is characterized in that the triangle fixing plate is fixedly installed on the bottom plate structure of the same-row hanging eye by a support rod. The triangle fixing plate includes an upper triangle fixing plate, a middle triangle fixing plate, and a lower triangle fixing plate. The purl triangle and the knitting triangle are fixed by the upper triangle fixing plate so that the triangle can only move up and down. The center purl triangle is fixed by the middle triangle fixing plate so that the triangle can only move up and down. The left needle starting triangle, the right needle starting triangle, the left needle joining triangle, and the right needle joining triangle are fixed by the lower triangle fixing plate so that the triangle can only move up and down.

[0015] Furthermore, the bottom plate device is characterized in that when the triangle moves upward and retracts into the bottom plate structure of the same-row hanging eye, the triangle does not contact the knitting needle or the selecting piece and is in a non-working state; when the triangle moves downward and protrudes from the bottom plate structure of the same-row hanging eye, the triangle contacts the knitting needle or the selecting piece and is in a working state.

[0016] Furthermore, the bottom plate device is characterized in that the upper cam controls the purl triangle and the knitting triangle. When the upper cam is in the up stroke, the upper cam contacts the bearing on the lifting seat to make the purl triangle and the knitting triangle move upward and retract into the bottom plate structure of the same-row hanging eye; when the upper cam is in the down stroke, the lifting seat makes the purl triangle and the knitting triangle move downward and protrude from the bottom plate structure of the same-row hanging eye under the action of the return spring.

[0017] Further, the bottom plate device is characterized in that the lower cam controls the left needle-raising triangle, the right needle-raising triangle, the left needle-connecting triangle, the right needle-connecting triangle, and the purl center triangle. When the lower cam is in the up stroke, the lower cam contacts the bearing on the lifting seat, causing the left needle-raising triangle, the right needle-raising triangle, the left needle-connecting triangle, and the right needle-connecting triangle to move upward and retract into the same-row hanging-eye bottom plate structure; when the lower cam is in the down stroke, under the action of the return spring, the lifting seat causes the left needle-raising triangle, the right needle-raising triangle, the left needle-connecting triangle, and the right needle-connecting triangle to move downward and protrude from the same-row hanging-eye bottom plate structure.

[0018] Further, the bottom plate device is characterized in that a guide post is installed on the purl center triangle. The guide post is installed in the middle triangle fixing seat and can move up and down. A sliding shaft sleeve is installed at the end of the guide post, and a return spring is installed between the sliding shaft sleeve and the middle triangle fixing seat.

[0019] Further, the bottom plate device is characterized in that when the lower cam is in the up stroke, the lower cam contacts the sliding shaft sleeve, causing the purl center triangle to move downward and protrude from the same-row hanging-eye bottom plate structure; when the lower cam is in the down stroke, under the action of the return spring, the purl center triangle moves upward and retracts into the same-row hanging-eye bottom plate structure.

[0020] Further, the needle-raising triangle is fixed by the needle-raising triangle fixing seat and can only move up and down. A rotating shaft is installed on the needle-raising triangle fixing seat. A pry bar and a connecting rod are installed at the rear of the needle-raising triangle fixing seat. The pry bar and the connecting rod rotate a certain angle with the rotating shaft as the midpoint. A bearing is provided on the pry bar, and the bearing contacts the needle-raising triangle cam. When the needle-raising triangle cam is in the up stroke, the needle-raising triangle cam contacts the bearing, causing the pry bar and the connecting rod to rotate around the rotating shaft, so that the needle-raising triangle rises and the needle-raising surface contacts the selecting needle piece. When the needle-raising cam is in the down stroke, the needle-raising triangle descends and does not contact the selecting needle piece, being in a non-working state.

[0021] An execution method of a bottom plate device is characterized in that the method includes: the seven-station control structure controls the same-row hanging-eye bottom plate structure to complete at least one of the seven steps of knitting, same-row hanging-eye belt knitting, purling, hanging-eye, left-row right-needle connecting, right-row left-needle connecting, and idle running. Among them, the same-row hanging-eye bottom plate structure includes a purling triangle, a knitting triangle, a left needle-raising triangle, a right needle-raising triangle, a left needle-connecting triangle, a right needle-connecting triangle, a purl center triangle, and a needle-raising triangle.

At this time, the left needle casting cam 4, the right needle casting cam 8, the left needle connecting cam 5, and the right needle connecting cam 7 contact the needle selecting pieces 11 and are in a working state. The purl center cam 6 is installed with a guide post B-2. The guide post B-2 is installed in the middle cam fixing seat B-1 and can move up and down. A sliding shaft sleeve B-4 is installed at the end of the guide post B-2. A return spring B-7 is installed between the sliding shaft sleeve B-4 and the middle cam fixing plate B-1. When the lower cam 16 is in the upstroke, the lower cam 16 contacts the sliding shaft sleeve B-4, causing the purl center cam 6 to move downward and protrude from the same-row hanging-eye bottom plate structure. At this time, the purl center cam 6 contacts the needle selecting pieces 11 and is in a working state. When the lower cam 16 is in the downstroke, under the action of the return spring B-7, the purl center cam 6 moves upward and retracts into the same-row hanging-eye bottom plate structure. At this time, the purl center cam 6 does not contact the needle selecting pieces 11 and is in a non-working state. The needle lifting cam 3 is fixed by the needle lifting cam fixing seat C-1 and can only move up and down. A rotating shaft C-2 is installed on the needle lifting cam fixing seat C-1.

The pry bar C-3 and the connecting rod C-4 rotate a certain angle with the rotating shaft C-2 as the midpoint. A bearing is provided on the pry bar C-3. The bearing contacts the needle lifting cam 17. When the needle lifting cam 17 is in the upstroke, the needle lifting cam 17 contacts the bearing, causing the pry bar C-3 and the connecting rod C-4 to rotate around the rotating shaft C-2, making the needle lifting cam 3 rise and the needle lifting surface contact the needle selecting pieces 11. When the needle lifting cam 17 is in the downstroke, the needle lifting cam 3 descends and does not contact the needle selecting pieces 11 and is in a non-working state.
