Description

Technical Field

[0001] The utility model relates to the technical field of knitting flat needles, in particular to a knitting needle assembly of a flat knitting machine. Background Art

[0002] The knitting machine achieves the knitting of fabrics by the regular lifting and lowering of the knitting needles to achieve the actions of yarn padding, closing, looping, bending, looping and looping. When the knitting needles are rising, the coils gradually withdraw from the needle hooks, the needle tongues are opened, and the needle tongues are withdrawn and hung on the needle bar. When the knitting needles are descending, the needle hooks hook the newly placed yarn and pull it to bend into coils. At the same time, the original coils are unhooked, and the new coils pass through the old coils and are connected in series with the old coils. The multiple coil strings formed by many knitting needles are connected to each other to form a woven fabric.

[0003] Knitting needles are the core knitting parts of knitting machines. There are two main types of knitting needles in existing knitting machines. One type is the knitting needles with butts, that is, during the loop-forming process of the local knitting needles, the adjacent knitting needles that do not participate in knitting will also be acted on the butts by the density triangle on the machine head and move downward (in the loop-forming direction), causing the coils to be damaged and "holes" to form in the fabric. Another type of knitting needles do not include butts, but are equipped with needle feet. Knitting machines equipped with this type of knitting needles usually have a wider needle bed, a large machine size, a high manufacturing cost, a large machine running resistance, a large driving power required, and unstable coordination during operation. Utility Model Content

[0004] In order to overcome the above-mentioned deficiencies in the prior art, the utility model provides a knitting needle assembly of a flat knitting machine, which makes the structure more stable during the knitting operation.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A knitting needle assembly of a knitting machine, the knitting machine includes a needle bed, the knitting needle assembly includes a knitting needle and a needle pusher foot, one end of the needle pusher foot is pivotally connected to the knitting needle, the knitting needle is installed on the needle bed, the end of the knitting needle close to the needle pusher foot is a cantilever end, and the cantilever end is provided with a supporting part, and the lower end of the supporting part abuts against the needle bed.

[0007] In the above technical scheme, one end of the needle pusher foot is pivotally connected to the middle part of the knitting needle, the front half of the knitting needle is installed on the needle bed, and the rear half is a cantilever end. The cantilever end cooperates with the needle pusher foot and does not contact the needle bed. The needle pusher foot will swing up and down relative to the knitting needle under the drive of the machine head, so that the upper end of the needle pusher foot protrudes out of or retracts into the needle bed. During the operation of the knitting needle, the cantilever end of the knitting needle will shake, resulting in a decrease in the stability of the knitting needle. Therefore, a support part is arranged at the cantilever end of the knitting needle, and the lower end of the support part abuts against the needle bed, which can better support the knitting needle and reduce the shaking of the knitting needle, thereby improving the weaving quality.

[0008] Preferably, the pin lifting foot is provided with an adjacent portion adjacent to the supporting portion, and the supporting portion and the adjacent portion are staggered in the thickness direction.

[0009] In the above technical solution, the pin pusher foot swings along the axis of the pivot position. In order to avoid overlapping interference between the support part and the pin pusher foot, the support part and the pin pusher foot are staggered in the thickness direction to avoid interference between the pin pusher foot and the support part during the swinging process.

[0010] Preferably, the supporting portion is provided with a first groove for reducing the thickness of the supporting portion, and the adjacent portion is provided with a second groove for reducing the thickness of the adjacent portion, the sum of the thicknesses of the supporting portion and the adjacent portion does not exceed the thickness of either the knitting needle or the needle push foot, the first groove and the second groove are arranged face to face, and the knitting needle and the needle push foot at least partially overlap in the thickness direction.

[0011] In the above technical solution, by respectively arranging the first groove and the second groove on the supporting part and the adjacent part, the thickness at the two positions is reduced, and at the same time the material thickness at other positions will not be changed. The two grooves are arranged face to face so that the thickness of the mating parts superimposed together can be reduced, and the overall thickness of the knitting needle assembly can be reduced, thereby reducing the overall volume of the knitting machine.

[0012] Preferably, the needle pin has a needle clock, and the needle clock has a first inclined surface. The knitting machine also includes an auxiliary needle, and one end of the auxiliary needle is provided with a pushing part, and the pushing part has a second inclined surface slidably connected to the first inclined surface.

[0013] In the above technical solution, when the auxiliary stitch needs to push the needle pin to work, the second inclined surface of the pushing part will contact the first inclined surface of the needle clock, so that the auxiliary stitch can push the needle pin more smoothly, thereby improving the working smoothness and stability of the knitting machine needle assembly.

[0014] Preferably, a positioning groove is provided under the needle clock, and the positioning groove has a first side wall and a second side wall, and the first side wall and the second side wall are cross-arranged. When the auxiliary needle moves along the needle bed, the second inclined surface slides into the positioning groove along the first inclined surface, and a first push wall and a second push wall are respectively provided at both ends of the second inclined surface, and the first push wall abuts against the first side wall, and the second push wall abuts against the second side wall.

[0015] In the above technical solution, when the auxiliary stitch moves along the needle bed, the second inclined surface thereon will slide into the positioning groove along the first inclined surface of the needle clock. When the second inclined surface completely slides into the positioning groove, the first push wall and the second push wall respectively abut against the first side wall and the second side wall. Since the first side wall and the second side wall are cross-arranged, relative to a plane or two parallel surfaces, this solution can increase the support angle, so that the abutment between the auxiliary stitch and the needle push pin will become tighter and more stable, thereby enhancing the stability of the auxiliary stitch when pushing the needle push pin, reducing the shaking that may occur during the weaving process, and thus improving the quality of the woven product.

[0016] Preferably, the auxiliary stitch is also provided with a cantilever, and the pushing portion extends a third pushing wall in a direction away from the knitting needle. The knitting needle assembly also includes a limiting column acting on the third pushing wall, and there is a gap between the cantilever and the third pushing wall for the limiting column to slide, and the height of the gap is smaller than the diameter of the limiting column.

[0017] In the above technical solution, when the auxiliary stitch moves along the needle bed, the above-mentioned limiting column will move relatively with the auxiliary stitch in the gap. The diameter of the limiting column is greater than the height of the gap, which can increase the friction between the limiting column and the third pushing wall, thereby increasing the stability of the auxiliary stitch when the knitting needle assembly moves.

[0018] Preferably, a third groove cooperating with the limiting column is provided below the cantilever.

[0019] In the above technical solution, a third groove cooperating with the limiting column is provided under the cantilever. When the auxiliary stitch moves along the needle bed, it needs to remain stable in a fixed state. Therefore, the limiting column is limited by setting the third groove, so that the auxiliary stitch is more stable when the knitting needle assembly moves at high speed.

[0020] Preferably, a first notch is provided below the middle of the knitting needle, and a first flange matching the first notch is provided at one end of the needle lifting foot, and the contact position between the first flange and the first notch is arc-shaped.

[0021] In the above technical solution, the first notch is adapted to the first flange, so that the needle foot can be connected to the knitting needle assembly through the cooperation of the first flange and the first notch. In order to improve the smoothness of rotation, the contact position between the first flange and the first notch is arc-shaped. Since the arc-shaped structure usually has better sliding and rotation performance, a smoother arc surface contact is formed between the two. This contact mode reduces friction resistance, makes the rotation process smoother, and avoids the jamming phenomenon caused by friction.

[0022] Preferably, a first contact surface extends out from the entrance of the first notch, and a tail portion of the first flange extends to form a second contact surface that matches the first contact surface, and the first contact surface and the second contact surface fit together in a contact state.

[0023] In the above technical solution, the first contact surface and the second contact surface are in contact with each other. When the needle lifter foot cooperates with the knitting needle, the two contact surfaces will fit closely together to form a larger contact area, which not only increases the connection stability between the needle lifter foot and the knitting needle, but also makes the force more uniform. At the same time, the design of the first contact surface and the second contact surface also limits the free end of the needle lifter foot. During the knitting process, the needle lifter foot may be affected by various forces and cause slight displacement or shaking. However, due to the existence of the first contact surface and the second contact surface, these displacements or shaking will be limited to a smaller range, thereby ensuring the working stability of the knitting needle assembly.

[0024] The beneficial effects of the utility model are as follows: (1) the lower end of the support part abuts against the needle bed, which can better support the knitting needles and reduce the shaking of the knitting needles when the needle pusher foot swings, thereby improving the knitting quality; (2) by respectively arranging grooves on the support part and the adjacent part, the thickness of the two positions is reduced, and the material thickness of other positions will not be changed. The two grooves are arranged face to face, so that the thickness of the matching parts superimposed together can be reduced, which can reduce the overall thickness of the knitting needle assembly, thereby reducing the overall volume of the knitting machine; (3) The first side wall and the second side wall are arranged crosswise. Relative to a plane or two parallel surfaces, this scheme can increase the support angle, so that the abutment between the auxiliary pin and the needle pusher foot will become tighter and more stable, enhance the stability of the auxiliary pin when pushing the needle pusher foot to work, reduce the shaking that may occur during the knitting process, thereby improving the quality of the knitted product; (4) when the pushing part is placed in the groove, the abutment part will abut against the first inclined surface. In the process of the auxiliary pin pushing the needle pusher foot to work, not only does the pushing part form a stable support with the side wall of the positioning groove, but the abutment part also forms a stable contact with the first inclined surface, thereby increasing stability.

DETAILED DESCRIPTION

[0034] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0035] Embodiment 1:

[0036] like Figures 1 to 8 As shown, a knitting machine comprises a knitting needle assembly 1, a needle bed 2, an auxiliary pin 3, an insert 4 and a tooth plate 5, wherein the auxiliary pin 3 can slide in the front-rear direction relative to the needle bed 2 under the drive of a driving member, and the insert 4 and the tooth plate 5 are mounted on the needle bed 2 and are located at the front end of the knitting needle assembly 1. The knitting needle assembly 1 comprises a knitting needle 11 and a pin jack 12, one end of the pin jack 12 is pivotally connected to the knitting needle 11, and the knitting needle 11 is mounted on the needle bed 2, and one end of the knitting needle 11 close to the pin jack 12 is a cantilever end 111, and the cantilever end 111 is provided with a support portion 112, and the lower end of the support portion 112 abuts against the needle bed 2. Figure 1 and Figure 2 The X direction in the figure is the front-to-back direction. The insert piece 4 and the tooth-mouth piece 5 are located at the front of the needle bed 2 , and the auxiliary stitch 3 is located at the rear side of the knitting needle assembly 1 .

[0037] In the above technical scheme, one end of the needle pusher foot 12 is pivotally connected to the knitting needle 11, the front half of the knitting needle 11 is installed on the needle bed 2, and the rear half is a cantilever end 111. The cantilever end 111 cooperates with the needle pusher foot 12 and does not contact the needle bed 2. The needle pusher foot 12 will swing up and down relative to the knitting needle 11 under the drive of the machine head, so that the needle bell 123 at the upper end of the needle pusher foot 12 protrudes or retracts into the needle bed 2. During the operation of the knitting needle assembly, the cantilever end 111 of the knitting needle 11 will shake, resulting in a decrease in the stability of the knitting needle 11. Therefore, a support portion 112 is provided at the cantilever end 111 of the knitting needle 11, and the lower end of the support portion 112 abuts against the needle bed 2, which can better support the knitting needle 11 and reduce the shaking of the knitting needle 11 when the needle pusher foot 12 swings, thereby improving the weaving quality. Figure 1 The needle clock 123 at the upper end of the middle pin 12 is retracted back into the needle bed 2. Figure 2 The needle bell 123 at the upper end of the middle needle foot 12 protrudes from the needle bed 2.

[0038] Specifically, Figures 3 to 7 As shown, the needle jack foot 12 is provided with an adjacent portion 121 adjacent to the support portion 112, and the support portion 112 and the adjacent portion 121 are staggered in the thickness direction. Preferably, the support portion 112 is provided with a first groove 113 for reducing the thickness of the support portion 112, and the adjacent portion 121 is provided with a second groove 122 for reducing the thickness of the adjacent portion 121, and the sum of the thicknesses of the support portion 112 and the adjacent portion 121 does not exceed the thickness of either the knitting needle 11 or the needle jack foot 12, the first groove 113 and the second groove 122 are arranged face to face, and the knitting needle 11 and the needle jack foot 12 at least partially overlap in the thickness direction.

[0039] In the above technical solution, the pin jack foot 12 swings along the axis of the pivot position. In order to avoid overlapping interference between the support portion 112 and the pin jack foot 12, the support portion 112 and the pin jack foot 12 are staggered in the thickness direction to avoid interference between the pin jack foot 12 and the support portion 112 during the swinging process. By respectively setting grooves on the support portion 112 and the adjacent portion 121, the thickness of the two positions is reduced, and the material thickness of other positions will not be changed. The two grooves are set face to face, so that the thickness of the matching parts superimposed together can be reduced, which can reduce the overall thickness of the knitting needle assembly 1, thereby reducing the overall volume of the knitting machine.

[0040] Preferably, the needle jack 12 has a needle clock 123, and a bevel block 126 is provided on one side of the needle clock 123, and a first inclined surface 124 is provided on one side of the bevel block 126. The auxiliary needle 3 is provided with a pushing portion 31 at one end close to the needle clock 123, and the pushing portion 31 has a second inclined surface 32 slidably connected to the first inclined surface 124. A positioning groove 127 is provided below the needle clock 123, and the positioning groove 127 has a first side wall 128 and a second side wall 129, and the first side wall 128 and the second side wall 129 are arranged crosswise. When the auxiliary needle 3 moves along the needle bed 2, the second inclined surface 32 slides into the positioning groove 127 along the first inclined surface 124, and a first pushing wall 34 and a second pushing wall 35 are provided at both ends of the second inclined surface 32, respectively, and the first pushing wall 34 abuts against the first side wall 128, and the second pushing wall 35 abuts against the second side wall 129. The auxiliary stitch is also provided with a cantilever 36, and the pushing portion extends a third pushing wall 38 in the direction away from the knitting needle. The knitting needle assembly also includes a limiting column 21 acting on the third pushing wall 38. A gap 37 is provided between the cantilever and the third pushing wall 38 for the limiting column 21 to slide. The height of the gap 37 is less than the diameter of the limiting column 21. A third groove 361 cooperating with the limiting column 21 is provided below the cantilever 36. The third groove 361 includes two fixed positions. When the second inclined surface 32 slides into the positioning groove 127 along the first inclined surface 124, the limiting column 21 is fixed at the first fixed position. When the second inclined surface 32 slides out of the positioning groove 127, the limiting column 21 is fixed at the second fixed position.

[0041] In the above technical solution, when the auxiliary stitch 3 needs to push the needle pin 12 to work, the second inclined surface 32 of the pushing part 31 will contact the first inclined surface 124 of the needle clock 123, so that the auxiliary stitch 3 can push the needle pin 12 more smoothly, thereby improving the working smoothness and stability of the knitting machine needle assembly 1. When the auxiliary stitch 3 moves along the needle bed 2, the second inclined surface 32 thereon will slide into the positioning groove 127 along the first inclined surface 124 of the needle clock 123. When the second inclined surface 32 completely slides into the positioning groove 127, the first push wall 34 and the second push wall 35 respectively abut against the first side wall 128 and the second side wall 129. Since the first side wall 128 and the second side wall 129 are cross-arranged relative to a plane or two parallel surfaces, this scheme can increase the support angle, so that the abutment between the auxiliary stitch 3 and the needle pin 12 will become tighter and more stable, thereby enhancing the stability of the auxiliary stitch 3 when pushing the needle pin 12 to work, reducing the shaking that may occur during the weaving process, and thus improving the quality of the woven product. When the pushing portion 31 is placed in the groove, the abutting portion 36 will abut against the first inclined surface 124. In the process of the auxiliary pin 3 pushing the pin pin 12 to work, not only does the pushing portion 31 form a stable support with the side wall of the positioning groove 127, but the cantilever 36 also forms a stable contact with the third pushing wall, thereby increasing stability.

[0042] Preferably, the intersection angle between the first side wall 128 and the second side wall 129 is 90°.

[0043] Preferably, a first notch 114 is provided below the middle of the knitting needle 11, and a first flange 125 adapted to the first notch 114 is provided at one end of the needle support foot 12, and the contact position between the first flange 125 and the first notch 114 is in an arc shape. A first contact surface 115 extends from the entrance of the first notch 114, and the tail of the first flange 125 extends to form a second contact surface 6 that cooperates with the first contact surface 115, and the first contact surface 115 and the second contact surface 6 fit together in the contact state.

[0044] In the above technical solution, the first notch 114 is adapted to the first flange 125, so that the pin 12 can be connected to the knitting needle assembly 1 through the cooperation of the first flange 125 and the first notch 114. In order to improve the smoothness of rotation, the position where the first flange 125 contacts the first notch 114 is arc-shaped. Since the arc-shaped structure usually has better sliding and rotation performance, a smoother arc surface contact is formed between the two. This contact mode reduces the friction resistance, makes the rotation process smoother, and avoids the jamming phenomenon caused by friction. The first contact surface 115 and the second contact surface 6 are in contact. When the pin 12 cooperates with the knitting needle 11, the two contact surfaces will fit together tightly to form a larger contact area, which not only increases the connection stability between the pin 12 and the knitting needle 11, but also makes the force more uniform. At the same time, the design of the first contact surface 115 and the second contact surface 6 also limits the free end of the pin 12. During the knitting process, the pin 12 may be slightly displaced or shaken by various forces. However, due to the existence of the first contact surface 115 and the second contact surface 6, these displacements or shakes will be limited to a smaller range, thereby ensuring the working stability of the knitting needle assembly 1.

[0045] The beneficial effects of the utility model are: (1) the lower end of the support part 112 abuts against the needle bed 2, which can better support the knitting needle 11 and reduce the shaking of the knitting needle 11 when the needle leg 12 swings, thereby improving the knitting quality; (2) by respectively setting grooves on the support part 112 and the adjacent part 121, the thickness of the two positions is reduced, and at the same time, the material thickness of other positions will not be changed. The two grooves are set face to face, so that the thickness of the mating parts superimposed together can be reduced, which can reduce the overall thickness of the knitting needle assembly 1, thereby reducing the overall volume of the knitting machine; (3) The first side wall 128 and the second side wall 129 are cross-arranged. Relative to a plane or two parallel surfaces, this scheme can increase the support angle, so that the abutment between the auxiliary stitch 3 and the needle leg 12 will become tighter and more stable, enhance the stability of the auxiliary stitch 3 when pushing the needle leg 12 to work, reduce the shaking that may occur during the knitting process, thereby improving the quality of the woven product.
