Description

Position adjustable structure for horizontal needle of rib knitting machine
Technical Field
The utility model relates to a knitting machine's of rib horizontal needle adjustment structure.
Background
Referring to fig. 1, fig. 1 is a schematic view of a general rib knitting machine. In order to be able to weave complex patterns or colours, the principle of rib knitting machines is that a vertical group of needles 10A and a horizontal group of needles 10B are arranged in a rotating cylinder 1 which can be driven in rotation by a motor, the vertical needles of the vertical group of needles 10A and the horizontal needles of the horizontal group of needles 10B interlacing the yarn fed by the yarn feeding device.
Referring to FIG. 2, FIG. 2 is an exploded view of a rotary cylinder of a conventional rib knitting machine. The vertical needle group 10A of the rotary cylinder 1 is arranged vertically in a ring shape from the bottom of the plurality of vertical needles 4, and a driving lever 41 is additionally provided to drive the vertical needles 4 to move up and down. The horizontal needle group 10B of the rotary needle cylinder 1 is arranged above by a plurality of horizontal knitting needles 3 in a ring-shaped horizontal radial manner. The horizontal needles 3 are arranged in radial grooves of a horizontal dial 20 and thus can be stably moved in the grooves of the horizontal dial 20. The horizontal dial 20 rotates together with the vertical needle group 10A below to drive the horizontal knitting needle 3 to rotate, the upper horizontal needle track seat 21 is fixed, a track is arranged below the horizontal needle track seat 21, and the horizontal knitting needle 3 performs needle withdrawing or needle retracting along the track.
The track provided under the horizontal needle track seat 21 has different forms, and it is relatively simple to use a ring metal (not shown) having a curved path as the track for withdrawing and retracting the horizontal knitting needle 3.
Referring to fig. 3 and 4, fig. 3 is a perspective view of four sets of first track sets disposed on the horizontal needle track base of the rib knitting machine, and fig. 4 is a movement diagram of a single set of first track set disposed on the horizontal needle track base of the rib knitting machine. In order to make the needle-out stroke of the horizontal knitting needles 3 more finely adjustable to produce more interweaving variations, at least one first track group 5 capable of changing the needle-out stroke of the horizontal knitting needles 3 is arranged below the horizontal needle track seat 21 (for the sake of illustration, the horizontal needle track seat 21 is turned upwards in the drawings), four first track groups 5 are arranged in the example shown in fig. 3, and only one first track group 5 is reserved in fig. 4 for the sake of illustration.
The first track set 5 includes a first guiding track 51, an auxiliary track 52, a diameter-dividing track set 53 and a first narrowing track 54, and the diameter-dividing track set 53 further includes a lower track 531 and an upper track 532. The lower track 531 and the upper track 532 are overlapped, and the upper track 532 can adjust the angle relative to the lower track 531, so that the acting track surface (not shown, an outward arc surface in the drawing) can generate difference.
The lower track 531 may also have an arc-shaped slot (not labeled), the upper track 532 may have a driving rod (not labeled) controlled by an external motion mechanism through the arc-shaped slot, and the fine adjustment is performed by a computer program pulled by a power assembly such as a motor or an electromagnetic valve during the interlacing process.
The horizontal knitting needle 3 has two types of long knitting needles 31 and short knitting needles 32 in order to produce different motion paths corresponding to the lower track 531 and the upper track 532. The horizontal needles 3 are arranged radially, and for the sake of convenience of description, only one long needle 31 and one short needle 32 are shown in the drawings.
The long foot knitting needle 31 has the same basic configuration as the short foot knitting needle 32 except that the long foot 311 of the long foot knitting needle 31 is longer than the short foot 321 of the short foot knitting needle 32. The long leg 311 and the short leg 321 both extend into the first track group 5 and are pushed out or pushed back by the action surfaces of the respective tracks in a ramp principle.
Referring to fig. 3, 4 and 5, fig. 5 is a schematic diagram of the horizontal knitting needles of the rib knitting machine in the first arrangement of the first track set. The first guide rail 51 utilizes a single outer guide surface for the long foot 311 and the short foot 321 to slide through, so that the long foot knitting needle 31 or the short foot knitting needle 32 passes through the first guide rail 51 with the same protruding length.
Then, the long knitting needle 31 or the short knitting needle 32 is moved to the position of the auxiliary track 52, the auxiliary track 52 can protect the horizontal knitting needle 3 from being thrown out due to centrifugal force, and can also be used as a motion track to push the long knitting needle 31 and the short knitting needle 32 back inwards, so the auxiliary track 52 is not necessarily arranged.
Then, the long-foot knitting needle 31 or the short-foot knitting needle 32 moves to the position of the split track group 53, referring to fig. 5, the split track group 53 in fig. 5 is the first arrangement, the action surface of the upper track 532 is retracted compared with the action surface of the lower track 531, and the short foot 321 moves along the action surface of the upper track 532 to move along the path closer to the center of the circle because the short foot 321 has a shorter length and cannot touch the action surface of the lower track 531. Since the long leg 311 has a longer length and touches the action surface of the lower track 531 first, the long leg 311 moves along the action surface of the lower track 531 and moves along a path farther from the center of the circle. Therefore, the long knitting needle 31 or the short knitting needle 32 can be adjusted to different projecting lengths when going to the position of the split track group 53.
Finally, the long knitting needle 31 or the short knitting needle 32 is moved to the first narrowing rail 54, and the first narrowing rail 54 slides over the long knitting needle 311 and the short knitting needle 321 by using a single inner guide surface and has a large arc-shaped inward-bent inclined surface, so that the long knitting needle 31 or the short knitting needle 32 passes through the first narrowing rail 54 with the same retraction length. Thus, one cycle of needle withdrawing and needle retracting is completed, and the next track group is entered.
Referring to fig. 6, fig. 6 is a schematic diagram of the horizontal knitting needles of the rib knitting machine in the second arrangement of the first track set. Compared to the first arrangement of the split track set 53 in fig. 5 and the second arrangement of the split track set 53 in fig. 6, the action surface of the upper track 532 is the same as or more protruded than the action surface of the lower track 531, so that the short leg 321 and the long leg 311 both move along the action surface of the upper track 532 and follow the same path.
Referring to fig. 7, fig. 7 is a schematic diagram of the horizontal needles of the rib knitting machine in two arrangements of the first track set. Fig. 7 integrates the actions of the two arrangements shown in fig. 5 and fig. 6, the lower right corner of fig. 7 is the first arrangement shown in fig. 5, the long foot knitting needle 31 or the short foot knitting needle 32 moves to the position of the split track group 53, the short foot 321 moves along the action surface of the upper track 532 and moves along a path closer to the center of a circle, the long foot 311 moves along the action surface of the lower track 531 and moves along a path farther from the center of a circle, and when the long foot knitting needle 31 or the short foot knitting needle 32 moves to the position of the split track group 53, the long foot knitting needle 31 can extend outwards more than the short foot knitting needle 32. In the second arrangement of fig. 6, in the lower left corner of fig. 7, the knitting needle 31 of the long foot or the knitting needle 32 of the short foot takes the same path as the knitting needle 31 of the long foot to the position of the group 53 of the split tracks.
In summary, the first track group 5 can only adjust the path taken by the long stitch knitting needle 31 to be more projected or the same as the short stitch knitting needle 32, but cannot adjust the path taken by the short stitch knitting needle 32 to be more projected than the long stitch knitting needle 31, and the design of the knitting method for interlacing is limited, and therefore, improvement is required.

The thick black solid line in the figure is the knitting needle motion path 312, and the knitting needle 31 rotates to come to the first guide track 51, and the single outer arc surface is used for the long foot 311 to slide. Then, the long knitting needle 31 goes to the position of the auxiliary track 52, the auxiliary track 52 can protect the horizontal knitting needle 3 from being thrown out due to centrifugal force, and meanwhile, the long knitting needle 31 is pushed back inwards. Then, the long-foot knitting needle 31 moves to the position of the split track group 53, the long foot 311 with a longer length first touches the action surface of the lower track 531, moves along the action surface of the lower track 531, and moves along a path far away from the center of circle. Finally, the knitting needle 31 is moved to the first retracting track 54, and the first retracting track 54 draws the knitting needle 31 back into contact with the second guide track 61 by using the inner curved surface. The outer active surface of the second guide track 61 pushes the longfoot needle 31 to the outermost point. Then the long needle 31 rotates to the position of the front rail 62, the length of the long needle 311 contacts the front rail 62, so that the long needle 31 moves inwards from the acting surface of the inner side of the front rail 62 and jumps over the rear rail 63, finally, the long needle 31 rotates to the position of the second narrowing rail 64, the second narrowing rail 64 is in sliding contact with the long needle 311 by using an inner cambered surface, the long needle 31 is completely retracted when passing through the second narrowing rail 64, thereby the long needle 31 completes two needle withdrawing and narrowing periods, one is moved outwards compared with the short needle 32, and the other is moved inwards compared with the short needle 32.
FIG. 13 is a schematic view of the motion path of the short-legged knitting needle according to the structure of the adjustable position of the horizontal needle of the rib knitting machine of the present invention. Referring to fig. 13, the motion path of the knitting needle 32 is shown in particular for the sake of clarity. The thick black solid line in the figure is the motion path 322 of the knitting needle of the short foot, the knitting needle 32 of the short foot rotates to the first guide track 51, and the single outside arc surface of the knitting needle is used for the sliding of the short foot 321. Then, the knitting needle 32 of the short foot is moved to the position of the auxiliary track 52, the auxiliary track 52 can protect the horizontal knitting needle 3 from being thrown out due to centrifugal force, and the knitting needle 32 of the short foot is pushed back inwards. Then, the short-foot knitting needle 32 moves to the position of the split track group 53, and the short foot 321 has a shorter length, does not touch the action surface of the lower track 531 first, but moves along the action surface of the upper track 532 to move along a path closer to the center of the circle. Finally, the knitting staple 32 moves to the first narrowing track 54 position, and the first narrowing track 54 draws the knitting staple 32 back into contact with the second guide track 61 by means of the inner curved surface. The outer active surface of the second guide track 61 pushes the knitting staple 32 to the outermost point. Then the knitting needle 32 is rotated to the position of the front rail 62, the length of the short foot 321 does not contact the front rail 62, therefore the knitting needle 32 slips the front rail 62 and moves outwards from the action surface outside the rear rail 63, finally, the knitting needle 32 is rotated to the position of the second narrowing rail 64, the second narrowing rail 64 is in sliding contact with the short foot 321 by using the inner cambered surface, the knitting needle 32 is completely withdrawn when passing through the second narrowing rail 64, thereby, the knitting needle 32 completes two needle withdrawing and narrowing periods, one is moved inwards compared with the knitting needle 31, and the other is moved outwards compared with the knitting needle 31.
