Description
Technical Field
The invention relates to a horizontal needle adjusting structure of a rib knitting machine.
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 installed on the horizontal needle track base of the conventional rib knitting machine, and fig. 4 is a movement diagram of a single set of first track set installed on the horizontal needle track base of the conventional 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), and 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 through the pulling of 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 conventional first track set 5 can only adjust the path taken by the long stitch knitting needle 31 to be more protruded 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 protruded than the long stitch knitting needle 31, and the design of the knitting method for interlacing is limited, and therefore, it is necessary to improve the present invention.
In view of the above, the present inventors have made many years of experience in manufacturing, developing and designing related products, and have devised and evaluated the above objects in detail to obtain a practical invention.

Detailed Description
The embodiments of the present invention are described by way of example only, and are not intended to limit the scope of the invention.
In order to make the objects, features and advantages of the present invention comprehensible, preferred embodiments accompanied with figures are described in detail below. The terms first, second, etc. are used hereinafter to distinguish between different elements and are not intended to limit the order of the elements.
Referring to fig. 8 and 9, fig. 8 is an assembled perspective view of an embodiment of the adjustable position structure for the horizontal needles of the rib knitting machine of the present invention, and fig. 9 is a schematic movement diagram of the horizontal needles on the second guide track of the embodiment of the adjustable position structure for the horizontal needles of the rib knitting machine of the present invention.
In the present embodiment, a set of second track set 6 and three sets of conventional first track sets 5 are disposed on the horizontal needle track base 21. It can be understood that the present invention can be implemented by providing at least one second track group 6 on the horizontal needle track seat 21, and by using other conventional track devices, the present invention can achieve the purpose of pushing the short-foot knitting needle to move radially outward than the long-foot knitting needle.
Similarly, the present invention can arrange at least one second track set 6 on the horizontal needle track seat 21 and can arrange to find one known first track set 5, so as to achieve the purpose of arbitrarily adjusting the extending positions of different horizontal knitting needles.
Therefore, the implementation of the horizontal needle position-adjustable structure of the rib knitting machine of this embodiment mainly includes at least a horizontal needle track seat 21, a second track set 6, a long-foot knitting needle 31 and a short-foot knitting needle 32. The horizontal needle track base 21 is formed into a disk, and a plurality of screw holes or through holes are formed above the horizontal needle track base 21 for mounting various tracks.
The second track group 6 is disposed on the horizontal needle track base 21, the second track group 6 is sequentially disposed with a second guiding track 61, a front track 62, a rear track 63 and a second narrowing track 64, the front track 62 is lower than the rear track 63.
The long foot knitting needle 31 is provided with a long foot 311, and the length of the long foot 311 can contact the second guide rail 61, the front rail 62 and the second narrowing rail 64, but can not contact the rear rail 63.
The short foot knitting needle 32 is provided with a short foot 321, and the length of the short foot 321 can not contact the front rail 62, but can contact the second guide rail 61, the rear rail 63 and the second narrowing rail 64. Thereby, the short knitting needle 32 can be pushed further outward than the long knitting needle 31.
The long knitting needles 31 and the short knitting needles 32 belong to the horizontal knitting needles 3, and are radially disposed below the horizontal needle track seat 21, and for convenience of description, only one long knitting needle 31 and one short knitting needle 32 are illustrated.
Meanwhile, the actual position of the second track group 6 should be placed below the horizontal needle track seat 21, and for the sake of illustration, the horizontal needle track seat 21, the long-legged knitting needle 31, and the short-legged knitting needle 32 are drawn upside down.
Referring to fig. 9, when the long-foot knitting needle 31 or the short-foot knitting needle 32 rotates to reach the position of the second guide rail 61, the long foot 311 of the long-foot knitting needle 31 or the short foot 321 of the short-foot knitting needle 32 contacts an outward acting surface (not shown) of the second guide rail 61 and is pushed to the outermost point of the second guide rail 61 (refer to the rightmost vertex of the second guide rail 61 in fig. 8) according to the principle of a slope, and the outermost point is located at the path center line position of the front rail 62 and the rear rail 63.
Referring to fig. 10, fig. 10 is a schematic diagram of the movement of the horizontal knitting needles on the front rail and the rear rail according to the embodiment of the adjustable position structure of the horizontal needles of the rib knitting machine of the present invention. Looking first at the pony needle 32, when the pony needle 32 is rotated to the position of the front rail 62, the length of the pony 321 of the pony needle 32 cannot contact the front rail 62 and thus passes over the front rail 62 and then contacts the outwardly facing active surface of the rear rail 63, thereby pushing the more protruding of the pony needle 32 toward the outer diameter of the horizontal needle rail seat 21.
In this embodiment, a radial track group 53 may be added to the second track group 6, the radial track group 53 is disposed between the second guide track 61 and the first guide track 51, and the filling between the second guide track 61 and the first guide track 51 may avoid the disorder of knitting needles or the deviation of the tracks.
Referring to the knitting needle 31, when the knitting needle 31 rotates to the position of the front rail 62, the length of the long foot 311 of the knitting needle 31 contacts the front rail 62, and thus moves inward from the inward-facing action surface of the front rail 62, thereby pushing the knitting needle 31 inward toward the center of the horizontal needle rail seat 21. Then, the long knitting needle 31 does not touch the rear rail 63 and slips through the rear rail 63.
That is, the action surface of the inner surface of the front rail 62 contacts the long foot 311 to push the long foot knitting needle 31 toward the center of the horizontal needle rail seat 21, and the action surface of the outer surface of the rear rail 63 contacts the short foot 321 to push the short foot knitting needle 32 toward the outer diameter of the horizontal needle rail seat 21. Therefore, the long-legged knitting needle and the short-legged knitting needle can be pushed to the outer diameter more than the long-legged knitting needle at the yarn feeding point of the interweaving process.
Referring to fig. 11, fig. 11 is a schematic view of the horizontal needle moving on the second narrowing track according to the embodiment of the adjustable position structure of the horizontal needle of the rib knitting machine of the present invention. When the long knitting needle 31 or the short knitting needle 32 rotates to the position of the second narrowing rail 64, the second narrowing rail 64 utilizes a single inside arc surface for the long knitting needle 311 to slide in contact with the short knitting needle 321, and the end has an inward curved slope with a larger arc, so that the long knitting needle 31 or the short knitting needle 32 passes through the second narrowing rail 64 with the same retraction length. In this way, the long knitting needle 31 or the short knitting needle 32 completes a needle withdrawing and needle retracting cycle and enters the next track group.
In the above description, the second track set 6 mainly functions on the long leg 311 and the short leg 321 and how to change the motion track thereof, preferably, the present invention is to arrange at least one second track set 6 on the horizontal needle track base 21, and further comprises at least one first track set 5 arranged on the horizontal needle track base 21, the first track set 5 is sequentially provided with a first guiding track 51, a diameter dividing track set 53 and a first narrowing track 54, the diameter dividing track set 53 is provided with a lower track 531 and an upper track 532, the lower track 531 and the upper track 532 are overlapped, and the active surface of the upper track 532 can be aligned with the lower track 531 or retracted from the lower track 531, the length of the long leg 311 can contact the first guide track 51, the lower track 531 and the first narrowing track 54, the length of the short leg 321 can not contact the lower track 531, but can contact the first guide track 51, the upper track 532 and the first narrowing track 54.
Preferably, an auxiliary rail 52 is disposed between the first guide rail 51 and the radial rail set 53. Thereby, the short-foot knitting needle and the long-foot knitting needle can be ensured not to be thrown out by centrifugal force.
The first track set 5 is well known in the art, and the detailed description can refer to the description of the prior art.
FIG. 12 is a schematic view of the movement path of a long knitting needle according to the embodiment of the adjustable position structure of the horizontal needle of the rib knitting machine of the present invention. Referring to fig. 12, the movement path of the long knitting needle 31 is illustrated in particular for clarity. 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 knitting needle with short legs according to the embodiment of the adjustable position structure 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 slides over the front rail 62 and moves outwards from the action surface outside the back 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
Referring to fig. 14 and 15, for the sake of illustration, the horizontal needle track seat in the drawings is turned upwards, and a radial track group 71, a needle outlet track 72, a first guide track 73, a second guide track 74, a needle retracting track 75, a front track 76 and a rear track 77 are annularly arranged on the horizontal needle track seat 70 of the rib knitting machine.
The radial rail set 71 has an upper rail 711 and a lower rail 712 stacked on each other in a similar shape, the lower rail 712 is fixed on the horizontal needle rail seat 70, and the upper rail 711 can be adjusted in angle by reciprocating along the lower rail 712 or can be rotated outward in radial direction to be aligned with the lower rail 712.
The needle-out track 72 and the needle-dividing track group 71 are similar in shape and keep the same level height as the upper track 711, and the needle-out track 72 can make the same reciprocating and rotating angle adjustment as the upper track 711, and the outer edges of the needle-dividing track group 71 and the needle-out track 72 are arranged as the guide surfaces of the straight arc for the long leg 311 of the long-leg knitting needle 31 and the short leg 321 of the short-leg knitting needle 32 to smoothly slide.
The first guide rail 73 and the second guide rail 74 are disposed between the branch rail group 71 and the needle discharge rail 72 and maintain the same flat height, and the outer edges thereof maintain a smooth arc-shaped guide surface 731, 741 with the branch rail group 71 and the needle discharge rail 72, and a recessed surface 732, 742 is disposed on the guide surface 731, 741 of the first guide rail 73 and the second guide rail 74, and a vertex 743 is disposed on the second guide rail 74 toward one side along the recessed surface 742.
The narrowing track 75 is disposed outside the recesses 732, 742 of the first and second guide tracks 73, 74, and an inner stop surface 751, which is provided with a large arc shape at an angle on an inner side surface thereof, extends toward the radial track group 71, and the inner stop surface 751, the radial track group 71 and the first guide track 73 keep a space to restrict the operation of the long knitting needle 31 and the short knitting needle 32.
The front rail 76 and the rear rail 77 are provided at the vertex 743 side of the second guide rail 74, the front rail 76 and the rear rail 77 respectively maintain the width of the long leg 321 of the long leg knitting needle 32 with the narrowing rails 75 at both sides so as to facilitate the long leg 321 to travel, and the front rail 76 is shorter than the rear rail 77 so that the length of the short leg 311 of the short leg knitting needle 31 cannot contact the front rail 76 and can slide along the rear rail 77.
Wherein, the heights of the needle-out rail 72, the first guide rail 73, the second guide rail 74, the narrowing rail 75 and the rear rail 77 are kept at the same level as the upper rail 711 of the radial rail group 71, so as to ensure the smooth operation of the long knitting needles 31 and the short knitting needles 32 of the horizontal dial 20.
Referring to fig. 15, when the upper track 711 and the needle-out track 72 of the radial track set 71 are adjusted to a half-angle position of the lower track 712 by inward rotation, the traveling path of the short leg 321 of the short leg knitting needle 32 can sequentially travel along the outer guide surface of the upper rail 711, the guide surfaces 731, 741 of the first guide rail 73 and the second guide rail 74, and the recessed portions 732, 742, until the short leg 321 of the short leg knitting needle 32 travels to the vertex 743 of the second guide rail 74, the short leg knitting needle 32 is pushed outward, so that the short foot 321 can just cross the front rail 76 and slide along the outer side of the rear rail 77 to the inner stop surface 751 of the narrowing rail 75 to the recessed parts 732, 742 of the first guide rail 73 or the second guide rail 74, thereby, by using the design that the front rail 76 is shorter than the vertex 743 of the rear rail 77 and the second guide rail 74, the traveling path of the short foot knitting needle 32 can cross the front rail 76 to the rear rail 77 through the vertex 743 to achieve the purpose of pushing outwards.
When the upper track 711 is adjusted to be completely pushed outwards (see fig. 16), the knitting needle 32 with short foot can completely push outwards when moving to the upper track 711, and when the upper track 711 is adjusted to be completely pushed inwards (see fig. 17), the knitting needle 32 with short foot can completely retract when moving to the upper track 711, so that the moving path of the knitting needle 32 with short foot can change the interweaving mode according to the different adjustment angles of the upper track 711.
Meanwhile, the path of the long needle 311 of the long needle 31 is pushed outward along the guide surface of the lower rail 712 of the split rail set 71, and then slides to the recessed parts 732, 742 of the first guide rail 73 or the second guide rail 74 along the inner step surface 751 of the narrowing rail 75, and then continuously moves to the needle discharging rail 72 along the guide surfaces 731, 741 of the first guide rail 73 or the second guide rail 74, when the needle discharging rail 72 is adjusted to be pushed outward completely (see fig. 16), the long needle 31 moves to the needle discharging rail 72 to be pushed outward completely, and when the needle discharging rail 72 is adjusted to be pushed inward completely (see fig. 17), the long needle 31 moves to the needle discharging rail 72 to be retracted completely, so that the path of the long needle 31 can be changed with the adjustment angle of the needle discharging rail 72 to be interlaced.
Thus, the short-foot knitting needle 32 and the long-foot knitting needle 31 can make reciprocating rotation angle adjustment by utilizing the upper track 711 and the needle-out track 72 of the split track group 71, so that when the short-foot knitting needle 32 travels to the upper track 711, the short-foot knitting needle 32 can be completely pushed outwards or completely retracted along with the angle of outward movement (see fig. 16) or inward movement (see fig. 17) of the upper track 711, while the long-foot knitting needle 31 can be completely pushed outwards or completely retracted along with the angle of outward movement (see fig. 16) or inward movement (see fig. 17) of the needle-out track 72, thereby providing a knitting machine capable of controlling the traveling path of the long-foot knitting needle 31 and the short-foot knitting needle 32 by adjusting the angle of the upper track 711 and the needle-out track 72 at any time according to the requirement of the fabric, so as to achieve a multi-adjustment and variable interweaving manner of a single knitting machine, so as to increase the industrial demand and market competitiveness.
Wherein, the vertex 743 can be designed as a single component and forms a separate design with the second guiding track 74, and is hidden, the walking interweaving change of the long knitting needle 31 and the short knitting needle 32 can be controlled by adjusting the vertex 743, and the vertex 743 is hidden in the horizontal needle track seat 70.
