Description

Technical Field

[0001] The utility model shows a knitting needle assembly of a flat knitting machine and the flat knitting machine, belonging to the technical field of flat knitting machines. Background Art

[0002] The knitting machine achieves the actions of yarn padding, closing, looping, bending, looping and forming through the regular rising and falling movements of the knitting needles, thereby completing the weaving of the fabric; when the knitting needles are rising, the coil gradually withdraws from the needle hook, the needle tongue is opened, and the needle tongue is withdrawn and hung on the needle bar; when the knitting needles are descending, the needle hook hooks the newly placed yarn and pulls and bends it into a coil, while the original coil is unhooked, and the new coil passes through the old coil and is connected in series with the old coil, and the multiple coil strings formed by many knitting needles are connected to each other to form a woven fabric.

[0003] The knitting needles of a knitting machine run in the needle groove of the needle bed, and the lower bottom of the knitting needle contacts the bottom surface of the needle groove, and the two side surfaces of the knitting needle correspond to the two side walls of the needle groove. A needle ruler is provided at the upper bottom of the knitting needle, and a gap must be left between the needle ruler and the upper bottom of the knitting needle. The knitting needle cannot run without a gap, but when the gap is too large, it will also cause the knitting needle to run unsteadily, affecting the quality of the fabric; therefore, under the condition of ensuring that the knitting needle can run reliably, it is usually hoped that the gap between the needle ruler and the knitting needle is as small as possible. Due to the processing technology of the needle ruler and the dovetail groove that cooperates with the needle ruler, and the needle ruler is prone to slight deformation, the gaps between different knitting needles and the needle ruler on the same needle bed are different. The gaps between some knitting needles and the needle ruler are smaller, and the gaps between some knitting needles and the needle ruler are larger. This coordination between the knitting needle and the needle ruler affects the smooth operation of the knitting needle, and thus affects the quality of the woven fabric. Utility Model Content

[0004] The utility model aims to solve the problem in the prior art that the matching mode between the knitting needle and the needle ruler easily affects the stability of the knitting needle operation. To this end, a knitting needle assembly and a knitting machine are provided. The knitting needle is kept in contact with the bottom of the needle groove by an elastic pressure strip, thereby improving the stability of the knitting needle operation.

[0005] To solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A knitting needle assembly of a flat knitting machine comprises a needle bed, knitting needles and a plurality of inserts arranged on the needle bed at intervals, a needle groove for the knitting needles to slide is formed between two adjacent inserts, a needle pressing device is installed on the insert, the needle pressing device acts on the knitting needles to limit the knitting needles from leaving the needle grooves, the needle pressing device comprises a needle ruler and an elastic pressure strip, the elastic pressure strip has a deformation part, the deformation part abuts against the knitting needles and generates deformation so that the knitting needles keep in contact with the bottom of the needle groove, and in the sliding direction of the knitting needles, both sides of the deformation part have guide surfaces.

[0007] The beneficial effects of adopting the utility model are:

[0008] The needle pressing device described in the utility model comprises a needle ruler and an elastic pressure strip, the deformation part of the elastic pressure strip abuts against the knitting needle, so that the knitting needle can maintain stable contact with the bottom of the needle groove, thereby improving the smoothness of the sliding of the knitting needle. At the same time, since the deformation part is elastic, the force exerted by the deformation part on the knitting needle can be flexibly changed, thereby preventing the knitting needle from being unable to slide normally due to excessive pressure on the knitting needle. In addition, since the gaps between the knitting needle and the needle ruler on the same needle bed are not the same, the elastic pressure strip can keep the deformation part in stable contact with the knitting needle under the action of its own elasticity, thereby improving the smoothness of the sliding of the knitting needle. It can be adapted to all knitting needles so that all knitting needles can maintain stable sliding, which can effectively improve the knitting quality of the knitting needles; secondly, in the sliding direction of the knitting needles, both sides of the deformation part have guide surfaces, which can reduce the contact area between the deformation part and the knitting needles, thereby reducing the friction between the deformation part and the knitting needles, reducing the resistance encountered by the knitting needles during sliding, making the sliding of the knitting needles smoother and more stable, reducing the possibility of the knitting needles getting stuck due to excessive resistance, and also reducing the possibility of the knitting needles being worn due to the deformation part, which helps to extend the service life of the knitting needles.

[0009] Preferably, the bottom of the needle ruler is provided with a groove for installing an elastic strip, the elastic strip has an abutment portion, the abutment portion abuts against the inner wall of the groove, and the deformation portion has a deformation tendency protruding from the groove. With the aforementioned technical solution, part of the elastic strip extends into the groove, which helps to reduce the gap between the needle ruler and the knitting needle, thereby preventing the knitting needle from shaking significantly during the sliding process, and also reduces the overall thickness of the knitting needle assembly, making the overall structure of the knitting needle assembly more compact; in addition, the abutment portion abuts against the inside of the groove, and the groove can limit the abutment portion, thereby reducing the sliding range of the elastic strip, preventing the elastic strip from detaching from the needle ruler, and helping to improve the coordination stability between the elastic strip and the needle ruler.

[0010] Preferably, the middle of the elastic strip is depressed downward to form a deformation part, and the two sides of the elastic strip form abutment parts, which are higher than the deformation part and abut against the needle ruler, and the deformation part is deformed to change the distance between the two sides, and the guide surface is between the abutment part and the deformation part. With the above technical solution, the deformation part is formed by the depression in the middle of the elastic strip, which can make the contact surface between the deformation part and the knitting needle more rounded, making the sliding between the deformation part and the knitting needle smoother, and also can reduce the damage caused by the deformation part to the knitting needle.

[0011] Preferably, the elastic pressure strip has a deformation state in which the deformation part and the knitting needle are against each other, and the spacing between the two sides of the elastic pressure strip is smaller than the width of the groove when the deformation part is in the deformation state. With the above-mentioned technical solution, when the deformation part contacts the knitting needle, the elastic pressure strip is squeezed in a deformation state, and the spacing between the two sides of the elastic pressure strip is larger than the spacing between the two sides when no deformation occurs. Therefore, during the deformation process, the spacing between the two sides of the elastic pressure strip will increase, and during the sliding process of the knitting needle, the extrusion force on the elastic pressure strip may increase, which may cause the two sides to move away from each other. Increasing the width of the groove can provide sufficient deformation space for the elastic pressure strip, and prevent the elastic pressure strip from being stuck in the knitting needle due to the inability to continue to deform.

[0012] Preferably, one side of the elastic pressure strip is fixed to the needle ruler, and the other side extends to the lower side of the needle ruler to form the deformation portion.

[0013] Preferably, the elastic strip is in the shape of an elongated strip, the length direction of the elastic strip intersects with the sliding direction of the knitting needle, and the deformation portion is distributed along the length direction of the elastic strip. By adopting the above technical solution, all knitting needles can be restricted by one elastic strip, thereby improving the utilization rate of the elastic strip, reducing the number of elastic strips, and reducing the manufacturing cost of the knitting needle assembly.

[0014] Preferably, the top of each of the inserts is provided with a mounting groove for mounting a needle ruler, and the needle ruler is inserted into a plurality of mounting grooves at the same time to fix the needle ruler, and the elastic pressure strip is limited between the needle ruler and the mounting groove.

[0015] Preferably, the notch of the mounting groove is located at the top of the insert, and the width of the mounting groove gradually decreases from the bottom of the mounting groove to the notch. With the above technical solution, the mounting groove can restrict the needle ruler, preventing the needle ruler from detaching from the insert from the notch of the mounting groove, which helps to improve the installation stability of the needle ruler and the insert, making the overall structure of the knitting needle assembly more stable and reliable.

[0016] Preferably, a downwardly recessed avoidance notch is provided at the bottom of the mounting groove, the avoidance notch is located at the lower side of the deformation portion, and the deformation portion has a deformation tendency to extend into the avoidance notch.

[0017] The utility model also shows a knitting machine, including a needle selection mechanism and a knitting needle assembly, the needle selection mechanism includes a triangular base plate, the knitting needle assembly includes a needle bed, a needle selection foot, an auxiliary needle and a knitting needle, a plurality of inserts are arranged on the needle bed at intervals, a needle groove is formed between two adjacent inserts, the needle selection foot, the auxiliary needle and the knitting needle are all slidably installed in the needle groove, and the knitting needle assembly adopts a knitting needle assembly as described in any one of the above items.

[0031] Embodiment 1:

[0032] like Figures 1 to 6 As shown, this embodiment shows a knitting needle 3 assembly of a knitting machine, including a needle bed 1, a knitting needle 3 and a plurality of inserts 2 arranged at intervals on the needle bed 1, a needle groove 21 for the knitting needle 3 to slide is formed between two adjacent inserts 2, a needle pressing device 4 is installed on the insert 2, the needle pressing device 4 acts on the knitting needle 3 to limit the knitting needle 3 from leaving the needle groove 21, the needle pressing device 4 includes a needle ruler 41 and an elastic pressure strip 42, the elastic pressure strip 42 has a deformation portion 421, the deformation portion 421 abuts against the knitting needle 3 and generates deformation so that the knitting needle 3 maintains contact with the bottom of the needle groove 21, and in the sliding direction of the knitting needle 3, both sides of the deformation portion 421 have guide surfaces 423.

[0033] The needle pressing device 4 in this embodiment includes a needle ruler 41 and an elastic pressure strip 42. The deformation portion 421 of the elastic pressure strip 42 abuts against the knitting needle 3, so that the knitting needle 3 can maintain stable contact with the bottom of the needle groove 21, thereby improving the smoothness of the sliding of the knitting needle 3. At the same time, since the deformation portion 421 is elastic, the force exerted by the deformation portion 421 on the knitting needle 3 can be flexibly changed, thereby preventing the knitting needle 3 from being unable to slide normally due to excessive pressure on the knitting needle 3. In addition, since the gaps between the knitting needle 3 and the needle ruler 41 on the same needle bed 1 are not the same, the elastic pressure strip 42 can keep the deformation portion 421 and the knitting needle 3 in stable contact under the action of its own elasticity. Secondly, in the sliding direction of the knitting needle 3, both sides of the deformation part 421 have guide surfaces 423, which can reduce the contact area between the deformation part 421 and the knitting needle 3, thereby reducing the friction between the deformation part 421 and the knitting needle 3, reducing the resistance encountered by the knitting needle 3 during the sliding process, making the sliding of the knitting needle 3 smoother and more stable, reducing the possibility of the knitting needle 3 being stuck due to excessive resistance, and also reducing the possibility of the knitting needle 3 being worn due to the deformation part 421, which helps to extend the service life of the knitting needle 3.

[0034] like Figure 1 and Figure 5 As shown, in this embodiment, a plurality of inserts 2 are spaced apart on the needle bed 1, and a slot is formed between two adjacent inserts 2. The length direction of the slot coincides with the length direction of the knitting needle 3. The knitting needle 3 is placed in the slot and slides along the length direction of the slot. The top of each insert 2 is provided with a mounting groove 22 for mounting a needle ruler 41. The needle ruler 41 is inserted into a plurality of mounting grooves 22 at the same time to fix the needle ruler 41, that is, all the knitting needles 3 on the needle bed 1 can be restricted by one needle ruler 41. A groove 411 for mounting an elastic pressure strip 42 is provided at the bottom of the needle ruler 41. The groove 411 is distributed along the length direction of the needle ruler 41. The elastic pressure strip 42 has an abutment portion 422 that abuts against the elastic pressure strip 42. The portion 422 abuts against the inner wall of the groove 411, and the deformation portion 421 has a deformation tendency to protrude from the groove 411. Part of the elastic strip 42 extends into the groove 411, which helps to reduce the gap between the needle ruler 41 and the knitting needle 3, thereby preventing the knitting needle 3 from shaking significantly during the sliding process, and at the same time can also reduce the overall thickness of the knitting needle 3 assembly, making the overall structure of the knitting needle 3 assembly tighter; in addition, the abutting portion 422 abuts against the inside of the groove 411, and the groove 411 can form a limit for the abutting portion 422, thereby reducing the sliding range of the elastic strip 42, preventing the elastic strip 42 from detaching from the needle ruler 41, and helping to improve the matching stability between the elastic strip 42 and the needle ruler 41.

[0035] like Figure 5As shown, the elastic strip 42 described in this embodiment is in the shape of a long strip as a whole, and the length direction of the elastic strip 42 intersects with the sliding direction of the knitting needle 3. The middle part of the elastic strip 42 is recessed downward to form a deformation portion 421, and the deformation portion 421 is distributed along the length direction of the elastic strip 42. The two side edges of the elastic strip 42 form abutment portions 422, and the abutment portions 422 are higher than the deformation portion 421 and abut against the groove 411 of the needle ruler 41. The deformation portion 421 is deformed to change the distance between the two side edges, and the elastic strip 42 gradually bends upward from the deformation portion 421 to the abutment portion 422, and then a guide surface 423 can be formed on both sides of the deformation portion 421.

[0036] In this embodiment, the length direction of the elastic strip 42 intersects with the sliding direction of the knitting needle 3, and the deformation part 421 is distributed along the length direction of the elastic strip 42. Therefore, all the knitting needles 3 can be restricted by one elastic strip 42, thereby improving the utilization rate of the elastic strip 42, reducing the number of elastic strips 42, and reducing the manufacturing cost of the knitting needle 3 assembly; in addition, it can also reduce the contact area between the deformation part 421 and each knitting needle 3, thereby reducing the friction between the deformation part 421 and the knitting needle 3, reducing the resistance encountered by the knitting needle 3 during the sliding process, making the sliding of the knitting needle 3 smoother and more stable, and reducing the knitting needle 3 due to resistance The possibility of the knitting needle 3 being stuck due to being too large can also be reduced, and the possibility of the knitting needle 3 being worn due to the deformation portion 421 can also be reduced, which helps to extend the service life of the knitting needle 3; secondly, the deformation portion 421 is formed by the depression in the middle of the elastic pressure strip 42, which can make the contact surface between the deformation portion 421 and the knitting needle 3 more rounded, and make the sliding between the deformation portion 421 and the knitting needle 3 smoother, and at the same time can also reduce the damage caused by the deformation portion 421 to the knitting needle 3; furthermore, the guide surface 423 can make it easier for the knitting needle 3 to pass over the elastic pressure strip 42 during the assembly process, which helps to reduce the difficulty of installing the knitting needle 3 and can effectively improve the assembly effect of the knitting needle 3.

[0037] like Figure 2 and Figure 5 As shown, the elastic strip 42 in this embodiment has a deformation state in which the deformation portion 421 is against the knitting needle 3 and a natural state when the knitting needle 3 is not installed. When the elastic strip 42 is in the natural state, the knitting needle 3 is not installed in the needle groove 21. At this time, the elastic strip 42 is not squeezed by external force, and the deformation portion 421 protrudes from the groove 411. During the installation of the knitting needle 3, the bottom of the knitting needle 3 is against the bottom of the needle groove 21 and slides along the needle groove 21. When the knitting needle 3 slides the lower side of the elastic strip 42, the top of the knitting needle 3 first is against the guide surface 423, and the knitting needle 3 acts on the guide surface 423 and squeezes the elastic strip 42 under the guidance of the guide surface 423, so that the elastic strip 42 gradually shrinks into the groove 411 until the knitting needle 3 passes over the deformation portion 421. At this time, the deformation portion 421 is against the top of the knitting needle 3, and the deformation portion 421 is in a deformation state.

[0038] In addition, in the present embodiment, when the elastic pressure strip 42 is in a deformed state, the distance between the two abutment portions 422 is smaller than the width of the groove 411. When the deformed portion 421 contacts the knitting needle 3, the elastic pressure strip 42 is squeezed and is in a deformed state. At this time, the distance between the two side edges of the elastic pressure strip 42 is larger than the distance between the two side edges when no deformation occurs. Therefore, during the deformation process, the distance between the two side edges of the elastic pressure strip 42 will increase. During the sliding process of the knitting needle 3, the extrusion force exerted on the elastic pressure strip 42 may increase, which may cause the two side edges to move away from each other. Increasing the width of the groove 411 can provide sufficient deformation space for the elastic pressure strip 42, thereby preventing the elastic pressure strip 42 from being stuck in the knitting needle 3 due to its inability to continue to deform.

[0039] Of course, it is understandable that in other embodiments, the elastic pressure strip 42 may also have one side edge fixed to the needle ruler 41, and the other side edge extending to the lower side of the needle ruler 41 to form the deformation portion 421, and the bottom of the deformation portion 421 may be a downwardly protruding curved surface, and there is a deformation space between the deformation portion 421 and the needle ruler 41. In the process of the deformation portion 421 reaching the deformation state from the natural state, the deformation portion 421 deflects toward the needle ruler 41, thereby reducing the distance between the deformation portion 421 and the needle ruler 41.

[0040] like Figures 4 to 6 As shown, the mounting groove 22 described in this embodiment includes a notch, side walls 222 and a bottom wall 223, wherein the notch of the mounting groove 22 is located at the top of the insert 2, and the width of the mounting groove 22 gradually decreases from the bottom of the mounting groove 22 to the notch, that is, the side walls 222 gradually incline toward the outside of the notch from top to bottom, and the wall surfaces on both sides of the needle ruler 41 cooperate with the side walls 222 of the mounting groove 22. During the installation process, the needle ruler 41 is inserted into the mounting groove 22 from both sides of the insert 2. After the side walls 222 of the mounting groove 22 abut against the needle ruler 41, the needle ruler 41 can be limited to prevent the needle ruler 41 from detaching from the insert 2 from the notch of the mounting groove 22, which helps to improve the installation stability of the needle ruler 41 and the insert 2, and makes the overall structure of the knitting needle 3 assembly more stable and reliable.

[0041] In addition, the bottom of the mounting groove 22 described in the present embodiment is provided with a downwardly recessed avoidance gap 221, and the avoidance gap 221 is located at the lower side of the deformation portion 421. The deformation portion 421 has a deformation tendency to extend into the avoidance gap 221. When the elastic pressure strip 42 is in a natural state, the deformation portion 421 extends into the avoidance gap 221. The avoidance gap 221 can provide sufficient deformation space for the deformation of the elastic pressure strip 42.
