Abstract

The invention relates to a knitting needle, which comprises a needle hook, a needle tongue, a needle handle provided with a first transfer part and a groove, and a reed connected to the bottom surface of the groove and provided with a second transfer part and a protrusion, wherein a deformation surface is arranged between a connecting end of the reed connected with the bottom surface of the groove and the protrusion on the reed, the protrusion on the reed and the part of the deformation surface which is not exposed out of the groove or is exposed out of the groove can be elastically pressed in the groove by the needle groove, and a corresponding knitting needle inserted between the reed and the needle handle in the transfer knitting enables the deformation surface to rotate outwards due to the elastic deformation to drive the protrusion to expand outwards, so that coils hung on the first transfer part and the second transfer part are expanded. This results in the advantage that: the whole occupied space of the knitting needle is small, and the knitting needle is convenient to place in the needle groove; the stitch loop is small in expansion, but the stitch turning is reliable, so that the knitting density can be improved; the groove matched with the bulge does not need to be processed, so that the production efficiency is improved, and the cost is reduced; the steel sheet can be made thinner, making fine gauge knitting possible.

Description

Knitting needle

The technical field is as follows:

the present invention relates to needles for knitting, and in particular to needles for flat knitting machines.

Background art:

the flat knitting machine is symmetrically provided with a front needle bed and a back needle bed, the front needle bed and the back needle bed are respectively provided with needle grooves which correspond one to one, and knitting needles are respectively arranged in the needle grooves. As shown in fig. 39 and 40, the knitting needle generally has a hook a1, a latch a2 and a handle A3, the latch a2 is provided on the rear side of the hook a1, the hook a1 can be closed by rotating, the handle A3 is composed of a needle bar a31 and a needle body a32 which are sequentially provided on the rear portion of the hook, the needle body a32 is extended upward from the rear side of the needle bar in the width direction to be wider than the width of the needle bar, and a concave first transfer portion a4 is formed at the intersection of the front side of the needle body and the rear side of the needle bar.

When general knitting is carried out, the knitting needle moves up and down along the needle groove, so that a coil on the knitting needle moves relative to the knitting needle, and the needle latch is driven to rotate when the knitting needle moves to a position corresponding to the needle latch, so that the needle latch is closed or opened.

When the transfer knitting is carried out, two knitting needles in corresponding needle grooves on the front needle bed and the back needle bed are required to be mutually matched to perform the transfer, for example, if a coil of a knitting needle originally positioned in the one needle groove of the front needle bed is transferred to a corresponding knitting needle on the back needle bed, the corresponding knitting needle on the back needle bed is required to be inserted into the coil of the knitting needle on the front needle bed, in order to ensure the reliable insertion, a spring piece A5 provided with a bulge A51 is arranged on one side of a needle bar handle of the knitting needle, and the coil is relatively moved until the bulge of the spring piece is enlarged by the bulge, so that the corresponding knitting needle can be inserted into the enlarged coil.

The reed on the existing knitting needle is arranged in a groove on one side of a needle handle, the reed is basically and integrally bent into a trapezoidal protrusion A51 along the length direction of the knitting needle, referring to fig. 40, a needle hook insertion groove A511 is formed in the inner cavity of the protrusion A51, a connecting end A512 formed by connecting the rear side of the protrusion A51 with the bottom surface of the groove is arranged, and the front side of the protrusion is attached to the needle handle. The reed straddles the needle bar A31 and the needle body A32, and has a wide section and a narrow section, the part corresponding to the needle body A32 is wider than the part corresponding to the needle bar A31, the junction of the wide section and the narrow section forms a concave second transfer section A52, and the second transfer section A52 corresponds to the position of the first transfer section A4.

In the transfer knitting, the loop on the knitting needle is slid to the top end face A51a of the projection A51 by the front inclined face A51b of the projection and is expanded corresponding to the positions of the first transfer ring part and the second transfer ring part, therefore, the projection is higher than the side face of the corresponding needle handle, meanwhile, the knitting needle corresponding to the knitting needle is inserted into the hook insertion groove A511 from the lower part of the hook insertion groove and is inserted into the loop hung on the knitting needle, during the period, the knitting needle on the back needle bed generates the movement relative to the length direction of the knitting needle on the front needle bed, therefore, the hook insertion groove needs to be long enough to provide the movement space with the adaptive length; meanwhile, in order to make the coil to be expanded slide onto the top end surface A51a of the protrusion from the front side inclined surface A51b more easily, the inclination of the front side inclined surface is as gentle as possible, namely the inclination is small; similarly, in order to make the stitch more easily slide from the rear inclined surface a51c to the top end surface a51a, the inclination of the rear inclined surface a51c is also as small as possible, so that the convex part is too long and has poor rigidity, and the convex part is easy to deform when the stitch is obliquely pulled or transversely pulled, thereby being not beneficial to the insertion of a knitting needle and reducing the insertion reliability; if the inclination of the rear side inclined surface is large, the coil is not easy to slide to the top end surface of the protrusion from the rear side inclined surface of the protrusion, and the phenomenon that the coil is scraped can occur; to increase the rigidity of the spring and avoid the "scratch" phenomenon, the raised portion needs to be sufficiently high.

The prior art needles with spring blades described above also present problems: the protrusions on the reed are always higher than the corresponding side surfaces of the knitting needles, the knitting needles occupy large space, grooves matched with the protrusions need to be machined in the steel sheet forming the wall of the needle groove, and the protrusions are embedded in the grooves, so that the technological processes of steel sheet machining and needle plate installation are complex, the production efficiency is low, and the cost is increased; meanwhile, the steel sheet provided with the groove cannot be used for manufacturing a needle plate with fine needle pitch and cannot be suitable for weaving with finer needle pitch.

In addition, the existing knitting needle can not ensure that a latch of the receiving transfer knitting needle can be opened by the lower end of a hook insertion groove or the lower end of a needle handle of the knitting needle matched with the latch during transfer, usually by a transfer coil, when the latch of the corresponding knitting needle is opened by the transfer coil, the front end of the latch often pokes into a knitting line consisting of multiple strands of yarns, so that the phenomenon of 'single yarn' is caused, and therefore fabric flaws are generated.

The invention content is as follows:

the present invention is directed to overcome the above-mentioned deficiencies of the prior art and to provide a knitting needle. The technical scheme is as follows:

the knitting needle is arranged in the needle grooves on the front needle bed and the back needle bed of the flat knitting machine, can be mutually matched with the knitting needle in the corresponding needle groove on the back needle bed or the front needle bed, and comprises:

a needle hook is arranged on the needle hook,

a latch which is arranged at the rear side of the needle hook and can close the needle hook by rotating,

a needle handle consisting of a needle rod and a needle body which are arranged at the back part of the needle hook in sequence,

a concave first transfer ring part is formed at the joint of the needle bar and the needle body,

a groove arranged at one side of the needle handle,

a spring leaf provided with a concave second transfer ring part and a front part which is bent outwards along the length direction of the needle handle to form a convex rear part which is connected with the bottom surface of the groove to form a connecting end, and

a hook insertion groove formed by the inner cavity of the bulge;

wherein:

the reed is also provided with a deformation surface between the rear side of the protrusion and the front side of the connecting end, the deformation surface and the part of the protrusion not exposed out of the groove or exposed out of the groove can be elastically pressed in the groove by the needle groove, and

in the loop transfer knitting, a needle hook corresponding to a knitting needle in a needle groove is inserted between the reed and the needle handle through a needle hook insertion groove, so that the deformation surface generates elastic deformation to drive the protrusion to be outwards opened, and loops hung on the first loop transfer part and the second loop transfer part are expanded.

The knitting needle of the invention described in the above technical scheme drives the bulge to rotate outwards through the elastic deformation of the deformation surface to realize the ring expansion, thereby producing the following technical effects: 1) the whole reed on the knitting needle can sink in the groove on one side of the needle handle, so that the whole knitting needle occupies small space and is convenient to place in the needle groove; 2) because the widening ring is generated by the outward rotation of the bulge, the length and the height of the bulge can be reduced, so that the bulge rigidity can be increased, the bulge stability during the insertion of the knitting needle is improved, the widening ring of the coil is smaller, the needle turning is reliable, and the knitting density can be improved; 3) the steel sheet forming the needle groove is not required to be provided with a groove matched with the bulge, so that the processing of a knitting needle and the installation of a needle plate can be simplified, the production efficiency is improved, the cost is reduced, the steel sheet without the groove can be made thinner, the needle plate with finer needle pitch can be realized, and the knitting with finer needle pitch can be met;

the further technical scheme of the invention also comprises the following steps:

the deformation surface may have various configurations, for example, it may be a flat surface or an outwardly bent bending surface.

One side of the groove corresponding to the lower end of the hook insertion groove is provided with a guide groove which is communicated with the groove and is convenient for the insertion of the hook.

One side of the guide groove corresponding to the bottom surface of the groove is an inclined plane, so that the guide groove is in a horn mouth shape which is convenient for inserting the needle hook.

The front end of the hook of the knitting needle is provided with a hook guide part which is convenient to enter the hook insertion groove, so that the hook can be smoothly inserted into the hook insertion groove.

The needle hook guiding part is in a wedge shape which gradually shrinks forwards, and the narrowest part of the front end is smaller than the groove depth of the needle hook inserting groove; the depth of the groove is the depth of the inner cavity of the hour hook insertion groove in the direction vertical to the bottom surface of the groove when no knitting needle is inserted.

The lower end of the reed protrudes downwards corresponding to the front side of the second transfer ring part to form a latch opening part which is used for opening the latch of the knitting needle entering the hook insertion groove, so that the phenomenon of monofilament possibly occurring in transfer knitting is avoided.

The deformation surface and the bulge respectively correspond to the front part of the needle body and the rear part of the needle rod, and the front side edge of the deformation surface extends upwards from the rear side of the bulge along the width direction, so that the second loop transfer part is positioned at the joint of the deformation surface and the bulge.

The length of the deformation surface is greater than that of the bulge, so that the deformation surface has enough deformation.

The specific implementation mode is as follows:

the invention is further described below with reference to the figures and examples.

As shown in fig. 1, the knitting needles are provided in the needle grooves corresponding to the front needle bed 91 and the back needle bed 92 of the flat knitting machine, and if a knitting needle 1 is provided in any needle groove 911 of the front needle bed 91, a corresponding knitting needle 2 is provided in a needle groove 921 corresponding to the needle groove 911 on the back needle bed 92, and the knitting needle 1 and the knitting needle 2 have the same structure, and the knitting needle 1 and the knitting needle 2 need to be operated in cooperation with each other when performing the loop transfer knitting. The following examples all illustrate the construction of the needle according to the invention, by way of example of a needle 1.

Example 1

As shown in fig. 2 and 3, the knitting needle 1 has a hook 11, a latch 12 and a shank 13 composed of a shank 131 and a shank 132, the shank 132 being wider than the shank 131, which form a first loop 15 having a concave shape at the junction. A groove 133 is provided on the shank side of the knitting needle 1, and the groove 133 straddles the corresponding side surfaces of the needle bar 131 and the needle body 132. The reed 14 has a rear part with a wide section and a front part with a narrow section, the front part is bent outwards along the length direction of the needle handle to form a trapezoidal protrusion 141, the rear part of the reed is connected with the groove bottom 1331 of the groove 133 in a welding or riveting mode to form a connecting end 145, the lower end of the front side of the protrusion is attached to the groove bottom 1331 of the groove, and the inner cavity of the protrusion 141 forms a needle hook inserting groove 1411.

According to the invention, a deformation surface 142 is arranged between the protrusion 141 and the connecting end 145, and the deformation surface 142 is positioned at the rear part of the reed 14. The front side edge of the deformation surface extends upwards from the rear side of the bulge along the width direction, so that the second transfer part is positioned at the junction of the deformation surface and the bulge and corresponds to the position of the first transfer part 15.

The deformation surface 142 of the present embodiment is a bending surface formed by bending an outward triangle, the bending end can be similar to a bending point, and the deformation surface 142 and the protrusion 141 do not expose the groove 133 in a natural state without being affected by an external force; the deforming surface 142 and the protrusion 141 may be designed to have a portion exposing the groove 133 in a natural state, as shown in fig. 4, or have a portion (not shown) exposing the groove 133 in either one of them. If the bent end of the deformation surface 142 and the upper end surface of the protrusion 141 are exposed out of the groove 133, for example, as shown in fig. 4, the exposed part of the groove 133 is elastically pressed into the groove 133 when being constrained by the needle groove 911 (i.e., the corresponding groove wall 9111), as shown in fig. 5.

The depth of the hook insertion groove is the depth of the inner cavity in the direction perpendicular to the bottom surface of the groove, and the depth is the depth of the inner cavity under the static condition of the hook insertion groove when the corresponding knitting needle is not inserted, as shown in fig. 6. For the present embodiment, the distance between the inside of the tip end face 1412 of the hook insertion groove 1411 formed by the trapezoidal projection 141 and the groove bottom face 1331 forms a groove depth h, which is smaller than the thickness of the hook. The side of the groove corresponding to the lower end of the hook receiving slot 1411 is provided with a guide groove 134 which is communicated with the groove and is convenient for the insertion of the hook, and the side of the guide groove corresponding to the bottom surface of the groove is provided with a slope 1332, so that the lower end of the hook receiving slot is in a bell mouth shape. The hook 11 (21) of the knitting needle has a circular cross section, as shown in fig. 7, with a circular arc profile at the front end thereof, so that the knitting needle can be inserted into the hook insertion groove with relative ease.

At the beginning of transfer knitting, the spring plate of the knitting needle 1 is completely positioned in the needle groove 911, and if the deformed surface 142 and the protrusion 141 of the spring plate 14 are in the state shown in fig. 4, i.e. partially exposed out of the groove 133, they are elastically pressed into the groove 133 by the needle groove 911, see fig. 5. As the knitting needle 1 moves upward, the reed 14 moves out of the front end of the needle groove 911 to assume a natural state, and at this time, the loop X on the knitting needle 1 relatively moves to the first and second

loop transfer portions

15 and 15, and the latch of the knitting needle 2 to receive the loop X is closed on the hook and inserted into the hook insertion groove 1411 from the lower portion of the projection 141 on the knitting needle 1 by the guide groove 134 as shown in fig. 8. Since the depth h of the groove is smaller than the thickness of the hook, the insertion of the knitting needle 2 deforms the deformation surface 142 to drive the protrusion 141 to open outward, and the loop X starts to be opened, as shown in fig. 9. The needle 1 continues to move upwards, the needle 2 moves downwards relative to the needle 1 and moves relatively to the deformation surface 142, as shown in fig. 10 and 11, and the stitch X is further spread. In this embodiment, the lower end of the spring 14 is flat, the lower end of the corresponding hook insertion groove 1411 is also flat, and the latch 22 on the knitting needle 2 may be opened by touching the lower end of the guide groove 134 or the lower end of the hook insertion groove 1411 during the movement, for example, if the latch 22 is not opened yet, the knitting needle 2 enters the loop X from the hook insertion groove 1411, and is opened by touching the loop X, as shown in fig. 12. With the continued co-operation of the two needles, the loop X is completely inserted into the hook 21 of the needle 2, as shown in fig. 13. The needle 1 is then moved downwards so that the hook 21 with the loop X moves out of the spring 14 from the lower end of the front side of the projection 141, fig. 14, and the latch 12 of the needle 1 is closed by the loop X, which is completely moved out of the needle 1 and transferred onto the needle 2, fig. 15.

Example 2

The knitting needle structure of this embodiment is based on the above embodiment 1, and can be seen from fig. 2 to 5, the difference is only in the guiding groove 134 at the lower end of the hook insertion groove 1411, and the guiding groove 134 is a downward extension of the groove bottom 1331 corresponding to one side of the groove bottom of the groove, so that the lower end of the hook insertion groove is a flat insertion opening, fig. 16. In order to match the corresponding knitting needle to be smoothly inserted into the guide groove, the front end of the hook of the knitting needle of the embodiment is designed to be in a wedge shape which shrinks from width to front to the center, and the narrowest part of the front end is smaller than the depth of the groove, so that the hook can be conveniently inserted, as shown in fig. 17.

Other structures of the knitting needle of the embodiment and the process of the mutual matching of the two knitting needles in the transfer knitting are the same as those of the embodiment 1, and are not described again.

Example 3

The knitting needle 1 of the present embodiment has the same basic structure as the knitting needle of the embodiment 1, except that: the lower end of the spring 14 of the present embodiment is not straight, but a latch opening portion 144 is formed to protrude downward at a position corresponding to the front side of the second displacement portion. The latch opening part 144 is not lower than the lower end of the needle handle 13 and is used for opening the latch of the knitting needle entering the hook insertion groove, so that the problem that the latch cannot be reliably opened when the knitting needle to be inserted into a loop is inserted into the hook insertion groove carrying the knitting needle of the loop is solved, and the monofilament problem is effectively prevented.

In the transfer knitting, the knitting needle 2 is inserted into the guide groove from below the hook insertion groove 1411 of the knitting needle 1, the knitting needle 1 moves upward (the knitting needle 2 moves downward relative to the knitting needle 1), and the latch 21 touches the latch opening portion 144 protruding downward to be opened, as shown in fig. 19; the rest of the transfer process is the same as that of embodiment 1, and can be seen in fig. 11-15, and therefore, the description thereof is omitted.

Example 4

The knitting needle of the embodiment is based on the above embodiment 3, and the difference with the embodiment 3 is only the bending structure of the deformation surface on the spring plate 14, see fig. 18.

Referring to fig. 20, the transition surface 142 between the front side of the connecting end 145 and the rear side of the protrusion 141 of the spring 14 of the knitting needle of the present embodiment is a bending surface which is formed by bending outward in a trapezoidal shape, and the bending end is a plane. The deformation surface 142 and the protrusion 141 are not exposed out of the groove 133 in a natural state without being affected by external force, i.e. the whole spring leaf is sunk in the groove 133, and the outer end of the spring leaf is not protruded out of the corresponding side surface of the needle handle.

As shown in fig. 21 and 22, during transfer knitting, a knitting needle 2 corresponding to the knitting needle is inserted into a hook insertion groove 1411 formed by a spring plate protrusion 141 on the knitting needle, so that the deformation surface 142 is elastically deformed at an initial stage, the protrusion 141 moves outward, and a loop X starts to be widened; in the further transfer cooperation of the two knitting needles, the knitting needle 2 moves from the hook insertion groove 1411 to the deformation surface 142, so that the deformation surface 142 further elastically deforms and rotates outward, the loop X is further enlarged, and the whole transfer process is the same as that of embodiment 3, and is not described again.

Of course, the deformed surface 142 and the protrusion 141 of the trapezoidal bend on the spring 14 of the present embodiment may both expose the groove 133, or one of them may expose the groove 133, but the exposed portion may be elastically pressed in the groove 133 under the restriction of the needle groove.

Example 5

The knitting needle of the present embodiment is also based on the above embodiment 3, see fig. 18, and is different from the embodiment 3 only in the bending structure of the spring piece 14.

Referring to fig. 23, the protrusion 141 of the spring 14 of the knitting needle of this embodiment is an arc-shaped protrusion, and the deformation surface between the front side of the connecting end of the spring and the groove bottom surface of the groove and the rear side of the protrusion 141 is an outward arc-shaped bent surface, and the bent end is approximately a plane due to the large curvature radius of the arc. The deformation surface 142 and the protrusion 141 or either one of them is exposed from the groove 133 in a natural state without being applied with an external force, but the exposed portion can be elastically pressed in the groove, as shown in fig. 24.

As shown in fig. 25 and 26, in the transfer knitting, the knitting needle 2 corresponding to the knitting needle is inserted into the hook insertion groove 1411 formed by the spring projection 141 of the knitting needle, and the deformation surface 142 is elastically deformed to be initially rotated outward, so that the projection 141 is moved outward, and the stitch X is widened. As the knitting needle 2 continues to move relative to the knitting needle 1, the knitting needle moves from the hook insertion groove 1411 to the deformation surface 142, the deformation surface 142 elastically deforms and rotates outward again, the loop X is further enlarged, and the whole loop transfer process is the same as that of embodiment 3 and is not described again.

Of course, if necessary, the outer ends of the protrusions 141 and the deforming surfaces 142 of the needle spring 14 of the above-described embodiment may be configured to be sunk in the grooves so as not to expose the grooves.

Example 6

The knitting needle of the embodiment is also based on the above embodiment 3, and the difference from the embodiment 3 is only the bending structure of the deformation surface on the spring plate 14, see fig. 18.

The deforming surface 142 in this embodiment is a plane, and the deforming surface 142 is a plane extending forward from the connecting end 145 to the rear side of the protrusion 141 and fitting with the groove bottom 1331 of the groove 133. The protrusion 141 attached to the front side of the deformation surface 142 may not expose the groove 133, as shown in fig. 27; the recess 133 may also be exposed as in fig. 28, but the exposed portion may be resiliently compressed within the recess as in fig. 29.

As shown in fig. 30 and 31, during transferring knitting, the knitting needle 2 corresponding to the knitting needle is inserted into the hook insertion groove 1411 on the reed, so that the deformation surface 142 generates initial elastic deformation rotation, and then the knitting needle 2 is moved from the hook insertion groove to a position between the deformation surface and the groove bottom surface to perform further elastic deformation rotation, so as to drive the protrusion 141 to perform relatively large outward rotation, thereby obtaining a large loop expansion effect, so that the loop X is expanded, and the whole transferring process is the same as that of embodiment 3, and is not described again.

Example 7

The needle of this embodiment is substantially the same as that of embodiment 6 above, except that the planar deformation surface 142 does not engage the groove bottom surface of the groove, but is inclined slightly outwardly relative to the groove bottom surface. The protrusion 141 may not expose the groove 133, as shown in fig. 32; the groove 133 may also be exposed as in fig. 33, but the exposed portion may be pressed into the groove 133 by elastic deformation as in the above-described embodiment, as in fig. 34.

As shown in fig. 35 and 36, during transferring knitting, the knitting needle 2 corresponding to the knitting needle is inserted into the hook insertion groove 1411 on the reed, so that the deformation surface 142 generates initial elastic deformation rotation, and then the knitting needle 2 is moved from the hook insertion groove to a position between the deformation surface and the groove bottom surface to perform further elastic deformation rotation, so as to drive the protrusion 141 to perform relatively large outward rotation, thereby obtaining a further loop expansion effect, so that the loop X is expanded, and the whole transferring process is the same as that of embodiment 6, and is not described again.

Example 8

The present embodiment is based on embodiment 6, and is only the case where the groove depth h formed between the inner side of the tip end surface 1412 of the hook insertion groove 1411 and the groove bottom surface 1331 is not less than the thickness of the hook, and other configurations are the same as those of embodiment 6. In this case, when the hook 21 of the knitting needle 2 is inserted into the hook receiving groove 1411 as in the above embodiment 6, the spring plate 14 may not be elastically deformed to be outwardly rotated as shown in fig. 37, but when the knitting needle 2 moves from the hook receiving groove to a position between the deformed surface and the bottom surface of the groove, the deformed surface 142 is elastically deformed to cause the protrusion 141 to be outwardly expanded, and the stitches X on the first transfer portion and the second transfer portion are expanded as shown in fig. 38.

The present invention is not limited to the above-mentioned embodiments, and any technical solutions formed by combining or equivalently replacing the technical features provided by the inventive idea belong to the protection scope of the present invention.
