Description
Technical Field
The utility model belongs to the technical field of knitting machinery, in particular relates to a hosiery machine, and particularly relates to a left edge lifting assembly of the hosiery machine.
Background
The left corner is a control mechanism in the hosiery machine and is mainly used for controlling the number of knitting needles participating in knitting, namely controlling the number of rows of socks at different heights. Particularly in stockings, the ankle must be narrower than the calf, and if continued to extend upward, the sock needs to become wider; at this time, it is not enough to adjust the stitch density, and the number of the rows of the sock, that is, the number of stitches in each row, needs to be changed by lifting the left corner to change the number of knitting needles participating in knitting in each row.
The existing left corner lifting assembly is mostly pneumatically controlled, and the mode has the defects that the stroke is fixed, the stroke of the up and down movement of the left corner is the same, and the left corner lifting assembly is not flexible enough in adjustment. Chinese patent 201720391306.3 discloses a left corner control mechanism, which uses a motor to control a lever to push a left corner to move up and down. The technical proposal has the defects that the stroke of the lever is too long to be controlled accurately; meanwhile, when the rotation of the motor shaft is converted into linear motion of the lever, moment loss exists, and the lever is easy to wear.
Disclosure of Invention
The utility model aims to provide a left edge lifting assembly of a hosiery machine.
Therefore, the technical scheme adopted by the utility model is as follows: the left edge lifting assembly of the sock machine comprises a left edge, a lifting sliding block and a stepping motor, wherein the left edge is arranged on the lifting sliding block, and the stepping motor drives the lifting sliding block to move up and down through a transmission mechanism; the method is characterized in that: the transmission mechanism comprises a torsion bar, and the output end of the torsion bar is provided with a first swinging arm part which protrudes out; the lifting sliding block is provided with a stress end matched with the first swing arm part of the torsion bar.
Further, the lifting seat is further provided with a limiting groove at the front side, and the lifting sliding block is positioned in the limiting groove of the lifting seat and can slide up and down along the limiting groove.
And a reset spring is arranged between the lifting sliding block and the lifting seat.
The lifting seat is provided with a through hole, and the torsion bar is matched with the lifting sliding block after passing through the through hole.
The input end of the torsion bar is provided with a convex second swing arm part, and the motor shaft is abutted against the second swing arm part through a cam to drive the torsion bar.
The torque rod is used as a main transmission and force transmission component, so that the torque loss is small, and each transmission component has no larger change in stroke and is easier to control; the reset spring is arranged to enable the lifting sliding block to act more softly, so that accurate adjustment of the number of knitting needles is facilitated.

Detailed Description
See the drawings. The embodiment comprises a stepping motor 1, a cam 2 is sleeved on a motor shaft, and the motor is driven to rotate. The rear end of the torsion bar 8, i.e. the end facing the motor 1, of the second swing arm portion 5 is fixed to the torsion bar by a steel ring 6, a key 7. The second swing arm 5 is matched with the cam 2, and the rotation of the cam 2 drives the second swing arm to further drive the torsion bar to rotate. Meanwhile, a limiting block 4 is arranged on the torsion bar to limit the rotation angle of the torsion bar.
The front end of the torsion bar is provided with a lifting seat 9 and a lifting slide block 10, wherein the left side and the right side of the front side of the lifting seat 9 are provided with side walls, a limiting groove is formed between the two side walls, and the lifting slide block 10 is arranged in the limiting groove and can slide up and down in the limiting groove. The lifting seat is provided with a spring seat 92, the lifting slide block is provided with a spring propping part 101, one end of the reset spring 11 is arranged in the spring seat 92, and the other end of the reset spring is propped against the spring propping part 101 through the spring ejector rod 12, so that the lifting slide block has a tendency of being upwards propped by the spring.
The lifting seat 9 is provided with a through hole 91 which penetrates through, and the torsion bar 8 penetrates through the through hole 91 to be matched with the lifting slide block 10. Specifically, the front end of the torsion bar 8 is a first swing arm 81, the lifting slider has a stress end 102 facing the inner side of the lifting seat, and the first swing arm 81 abuts against and presses against the stress end 102.
In operation of this embodiment, the motor 1 drives the cam 2 to rotate, thereby pushing the torsion bar 8 to rotate as well, and the first swing arm 81 presses the force receiving end 102. The lifting slide is subjected on the one hand to the downward pressing force of the torsion bar 8 and on the other hand to the upward pushing force of the spring 11, the direction of movement of which depends on the magnitudes of these two forces. The up-and-down stroke of the elevation slider 10 can be precisely adjusted by the stepping motor.
