Description

Technical Field

[0001] This utility model relates to the field of knitting needle production technology, and more specifically to a multifunctional knitting needle. Background Technology

[0002] The knitting needles of a computerized flat knitting machine are an important component of the machine's knitting system. The needles move along the tracks formed by different triangular blocks through the movement of the needle pins, and at the same time, they use the needle selection push to complete different knitting methods at different heights, thereby knitting products with different patterns.

[0003] According to utility model patent application CN202047230U, published on November 23, 2011, a flat knitting needle is disclosed, comprising a needle hook, a needle bar, a needle heel, and a needle tail. The distance from the bottom edge of the needle bar to the upper edge of the needle heel is not greater than the height of the needle groove in the needle plate. An inclined surface is provided at the transition between the rear end face and the bottom face of the needle tail. Its main technical effect is that the selection of the flat knitting needle is achieved by moving the needle selector. When the flat knitting needle does not need to participate in knitting, the needle heel will not be higher than the needle groove, and therefore will not follow the knitting needle to the loop position, thus not affecting the quality of the garment piece. It also simplifies the mechanical structure and reduces the precision requirements of the machine.

[0004] In close-knit knitting, the increased number of needles leads to a decrease in the stitch spacing between two adjacent needles, which in turn reduces the cavity between the needle and the needle. Furthermore, the needle is prone to deformation during close-knit knitting due to the diagonal tension exerted by the coil, resulting in a high failure rate of the needle during this process. Therefore, this applicant proposes a multi-functional needle for close-knit knitting, aiming to solve the problem of high failure rate during close-knit knitting. Summary of the Invention

[0005] The purpose of this invention is to provide a multifunctional knitting needle for turning over needles, which aims to solve the problem of high failure rate of existing knitting needles during the turning over process when performing dense knitting.

[0007] A multifunctional knitting needle includes a needle body and a needle-turning spring. A needle-turning cavity is provided between the needle-turning spring and the needle body. The needle body has a corner arc surface. The needle-turning spring includes a needle-turning front end. The needle-turning front end is provided with a positioning abutment part facing the needle-turning cavity. One end of the positioning abutment part abuts against the outer wall of the needle body. By having the positioning abutment part on one needle body abut against the side wall of another needle body, a predetermined angle is formed between the end of the other needle body and one of the needle bodies.

[0008] Preferably, the front end of the flipping needle spring is provided with a flipping abutment part, which is located in front of the positioning abutment part.

[0009] Preferably, the number of the positioning abutment parts is two, and the two positioning abutment parts are staggered.

[0010] Preferably, the number of the flip-up abutment portions is two.

[0011] Preferably, a guide portion is provided on the outer wall of the flip-up abutment portion.

[0012] Preferably, the flipping needle spring further includes a flat portion and a connecting portion, with one end of the connecting portion connected to the flat portion and the other end connected to the front end of the flipping needle.

[0013] Preferably, the device also includes an abutment piece, which is riveted to the needle body and is located between the needle body and the needle-turning spring.

[0014] Preferably, the flipping abutment portion is an inverted triangular structure extending toward the knitting needle body, and the tip is provided with an arc-shaped chamfer, or an arc-shaped protrusion extending toward the knitting needle body.

[0015] In the above technical solution, the multifunctional knitting needle provided by this utility model has the following beneficial effects:

[0016] This utility model ensures that the turning needle cavity has a certain space by setting a positioning abutment part on the turning needle front end of the turning needle spring, which can prevent the turning needle spring from being deformed by the diagonal tension of the coil during the turning needle knitting process. At the same time, by abutting with another knitting needle body through the positioning abutment part, the other knitting needle body can be guided when turning needle knitting, thereby improving the success rate of turning needle knitting.

[0050] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0051] Please see Figure 1 —19, A multifunctional knitting needle, comprising a needle body 1 and a needle-turning spring 2, wherein a needle-turning cavity 3 is provided between the needle-turning spring 2 and the needle body 1, and a corner arc surface 11 is provided on the needle body 1, wherein the needle-turning spring 2 includes a needle-turning front end 21, and a positioning abutment part 211 facing the needle-turning cavity 3 is provided on the outer wall of one side of the needle-turning front end 21, one end of the positioning abutment part 211 abuts against the outer wall of the needle body 1, and the positioning abutment part 211 on one of the needle bodies abuts against the side wall of another needle body 1, so that the end of the other needle body 1 and one of the needle bodies 1 form a predetermined angle.

[0052] The front end of the flipping needle spring 2 is provided with a flipping abutment part 212, which is located in front of the positioning abutment part 211.

[0053] The number of the positioning abutment parts 211 is two, and the two positioning abutment parts 211 are staggered.

[0054] This utility model ensures that the needle-turning cavity 3 has a certain space by setting a positioning abutment part 211 on the needle-turning front end 21 of the needle-turning spring 2. This can prevent the needle-turning spring 2 from being deformed by the oblique tension of the coil during the needle-turning knitting process. At the same time, by abutting with another knitting needle body 1 through the positioning abutment part 211, the other knitting needle body 1 can be guided during the needle-turning knitting process, thereby improving the success rate of needle-turning knitting.

[0055] During the close-knitting process, the flipping abutment part 212 abuts against the needle tongue of another needle body 1, causing the needle tongue to open, thereby improving the success rate of flipping knitting.

[0056] It can achieve high-quality dense stitch knitting at a lower cost, resulting in good economic benefits.

[0057] As a first embodiment provided by this utility model, such as Figure 3As shown, there are two positioning abutment parts 211 and two flipping abutment parts 212. The two positioning abutment parts 211 are staggered, and the angle A between the line connecting the two positioning abutment parts 211 and the side wall of the flipping needle spring 2 is 90°-110°, preferably 100°. The two positioning abutment parts 211 guide the other needle body 1 so that the other needle body 1 forms an angle B with one of the needle bodies 1. The range of the angle B is the same as that of the angle A. The two positioning abutment parts 211 abut against the side wall of the needle body 1 to prevent the flipping needle from forming during the knitting process. The turn-over spring 2 is deformed by the diagonal tension of the coil. At the same time, it can abut against the side wall of another knitting needle body 1 through two positioning abutment parts 211 to position the other knitting needle body 1. When the outer arc surface of the hook of the other knitting needle body 1 is inserted into the turn-over cavity 3, the distance between the outer arc surface of the other knitting needle body 1 and the corner arc surface 11 of one of the knitting needle bodies 1 is ±0.9mm, so as to ensure that the hook part of the other knitting needle body 1 can hook the coil. Of course, for other special needle types, the above distance is not limited to ±0.9mm and can be set according to different needle types. There are two flip-abutment parts 212, which are staggered at the front end 21 of the flip needle. When the hook part of another needle body 1 is inserted into the flip needle cavity 3 inside one of the needle bodies 1 during the flip needle knitting, the flip-abutment part 212 provided on the flip needle spring 2 abuts against the needle tongue of the other needle body 1. The flip-abutment part 212 opens the needle tongue of the other needle body 1, so as to ensure that the needle tongue can still be opened in the smaller flip needle cavity 3, thus completing the flip needle knitting action. When the other needle body 1 is withdrawn from one of the needle bodies 1, the flip-abutment part 2122 is provided with a guide part 2121, which is specifically a bevel and an arc chamfer. The other needle body 1 can drive the flip needle spring 2 to open through the guide part 2121, so that the other needle body 1 can slide forward from the flip needle cavity 3.

[0058] As a second embodiment provided by this utility model, such as Figure 4As shown, there is one positioning abutment 211 and one flipping abutment 212. Preferably, both the positioning abutment 211 and the flipping abutment 212 are located on the upper edge of the side of the turning needle front end 21. By having one positioning abutment 211 located on the upper edge of the side wall of the turning needle front end 21 abut against the side wall of another needle body 1, deformation of the turning needle spring 2 caused by the diagonal tension of the coil is prevented during the turning needle knitting process. At the same time, the positioning abutment 211 can abut against the side wall of another needle body 1, and the positioning abutment 211 can provide abutment to the other needle body 1. The guide is used to position the other needle body 1 at an angle B to one of the needle bodies 1, with the angle B ranging from 90° to 110°, preferably 100°. The other needle body 1 is positioned such that when its hook outer arc surface is inserted into the turn-over cavity 3, the distance between the outer arc surface of the other needle body 1 and the corner arc surface 11 of one of the needle bodies 1 is ±0.9mm. This ensures that the hook portion of the other needle body 1 can hook the loop. Of course, for other special needle types, the above distance is not limited to ±0.9mm. 0.9mm, which can be set according to different needle types. When performing turn-over knitting, when the hook part of another needle body 1 is inserted into the turn-over cavity 3 inside one of the needle bodies 1, the flip-abutment part 212 set on the upper edge of the side wall of the turn-over front end 21 abuts against the needle tongue of the other needle body 1. The flip-abutment part 212 opens the needle tongue of the other needle body 1, so as to ensure that the needle tongue can still be opened in the smaller turn-over cavity 3. Or it can be applied to the smaller needle body 1 model, the smaller needle body 1 needle hook. The needle body is smaller, and its needle-turning cavity 3 is even smaller. With the structure provided in this application, it is possible to ensure that the needle tongue opens smoothly and completes needle-turning knitting and other actions when the small-sized needle body 1 is knitting. When another needle body 1 is pulled out from one of the needle bodies 1, since the flipping abutment part 212 is provided with a guide part 2121, which is specifically a bevel and an arc chamfer, the other needle body 1 can drive the needle-turning spring 2 to open through the guide part 2121, so that the other needle body 1 can slide forward from the needle-turning cavity 3.

[0059] As a third embodiment provided by this utility model, such as Figure 5 , Figure 20 and Figure 21As shown, there is one positioning abutment 211 and one flipping abutment 212. Preferably, both the positioning abutment 211 and the flipping abutment 212 are located on the lower edge of the side of the flipping needle front end 21. By abutting the side wall of the needle body 1 with the positioning abutment 211 located on the lower edge of the flipping needle front end 21, the deformation of the flipping needle spring 2 caused by the diagonal tension of the coil during the flipping needle knitting process is prevented. At the same time, the positioning abutment 211 can abut the side wall of another needle body 1. The positioning abutment 211 guides the other needle body 1 so that the other needle body 1 and one of the needle bodies 1 form an angle B. The angle B ranges from 90° to 110°, preferably 100°. The other needle body 1 is positioned so that when the outer arc surface of the hook of the other needle body 1 is inserted into the flipping needle cavity 3, the distance between the outer arc surface of the other needle body 1 and the corner arc surface 11 of one of the needle bodies 1 is ±0.9mm, so as to ensure that the other needle body 1 is positioned correctly. The hook part of the needle body 1 can hook the loop. Of course, for other special needle types, the above distance is not limited to ±0.9mm and can be set according to different needle types. When performing turn-over knitting, when the hook part of another needle body 1 is inserted into the turn-over cavity 3 inside one of the needle bodies 1, the flip-abutment part 212 provided on the lower edge of the side wall of the turn-over front end 21 abuts against the needle tongue of the other needle body 1. The flip-abutment part 212 opens the needle tongue of the other needle body 1 to ensure that the needle tongue can still be opened in the small turn-over cavity 3 to complete the turn-over knitting action. When the other needle body 1 is pulled out from one of the needle bodies 1, since the flip-abutment part 212 is provided with a guide part 2121, which is specifically a bevel and an arc chamfer, the other needle body 1 can drive the turn-over spring 2 to open through the guide part 2121, so that the other needle body 1 can slide forward from the turn-over cavity 3.

[0060] As a fourth embodiment provided by this utility model, such as Figure 6 As shown, there is one positioning abutment 211 and one flipping abutment 212. Preferably, the positioning abutment 211 is located on the lower edge of the side of the turning needle front end 21, and the flipping abutment 212 is located on the upper edge of the side of the turning needle front end 21. By having a positioning abutment 211 located on the lower edge of the side wall of the turning needle front end 21 abut against the side wall of the needle body 1, deformation of the turning needle spring 2 due to the oblique tension of the coil is prevented during the turning needle knitting process. Figure 20As shown, when another knitting needle body 2 is inserted into the lapping cavity 3 of one of the knitting needle bodies 2, it can abut against the side wall of the other knitting needle body 1 through the positioning abutment part 211 provided at the lower edge of the lapping front end 21. The positioning abutment part 211 guides the other knitting needle body 1 so that the other knitting needle body 1 and one of the knitting needle bodies 1 form an angle B, the range of which is 90°-110°, preferably 100°, to position the other knitting needle body 1. By flipping the abutment part 212 to open the needle tongue of the other knitting needle body 1, when the outer arc surface of the hook of the other knitting needle body 1 is inserted into the lapping cavity 3, the distance between the outer arc surface of the other knitting needle body 1 and the corner arc surface 11 of one of the knitting needle bodies 1 is ±0.9mm, so as to ensure that the hook part of the other knitting needle body 1 can hook the loop. Of course, for other special needle types, The above distance is not limited to ±0.9mm and can be set according to different needle types. When performing turn-knitting, when the hook part of another needle body 1 is inserted into the turn-knitting cavity 3 inside one of the needle bodies 1, the flip-abutment part 212 provided on the upper edge of the side wall of the turn-knitting front end 21 abuts against the needle tongue of the other needle body 1. The flip-abutment part 212 opens the needle tongue of the other needle body 1 to ensure that the needle tongue can still be opened in the small turn-knitting cavity 3, thus completing the turn-knitting action. When the other needle body 1 is withdrawn from one of the needle bodies 1, since the flip-abutment part 212 is provided with a guide part 2121, which is specifically a bevel and an arc chamfer, the other needle body 1 can drive the turn-knitting spring 2 to open through the guide part 2121, so that the other needle body 1 can slide forward from the turn-knitting cavity 3.

[0061] As the fifth embodiment provided by this utility model, such as Figure 7As shown, there is one positioning abutment 211 and one flipping abutment 212. Preferably, the positioning abutment 211 is located on the upper edge of the side of the turning needle front end 21, and the flipping abutment 212 is located on the lower edge of the side of the turning needle front end 21. By abutting against the side wall of the needle body 1 with one positioning abutment 211 located on the upper edge of the side wall of the turning needle front end 21, the deformation of the turning needle spring 2 caused by the diagonal tension of the coil during the turning needle knitting process can be prevented. At the same time, the positioning abutment 211 located on the upper edge of the side wall of the turning needle front end 21 can also prevent the turning needle spring 2 from being deformed by the diagonal tension of the coil during the turning needle knitting process. The positioning abutment part 211 abuts against the side wall of another knitting needle body 1 to position the other knitting needle body 1. The positioning abutment part 211 guides the other knitting needle body 1 so that the other knitting needle body 1 and one of the knitting needle bodies 1 form an angle B. The angle B ranges from 90° to 110°, preferably 100°. When the outer arc surface of the hook of the other knitting needle body 1 is inserted into the needle-turning cavity 3, the outer arc surface of the other knitting needle body 1 and the corner arc surface 11 of one of the knitting needle bodies 1 are aligned. The distance is ±0.9mm to ensure that the hook part of the other needle body 1 can hook the loop. Of course, for other special needle types, the above distance is not limited to ±0.9mm and can be set according to different needle types. When performing turn stitch knitting, when the hook part of the other needle body 1 is inserted into the turn stitch cavity 3 inside one of the needle bodies 1, the flipping abutment part 212 provided on the lower edge of the side wall of the turn stitch front end 21 abuts against the needle tongue of the other needle body 1. The flipping abutment part 212 opens the needle tongue of the other needle body 1 to ensure that the needle tongue can still be opened in the small turn stitch cavity 3 to complete the turn stitch knitting action. When the other needle body 1 is pulled out from one of the needle bodies 1, since the flipping abutment part 212 is provided with a guide part 2121, which is specifically a bevel and an arc chamfer, the other needle body 1 can drive the turn stitch spring 2 to open through the guide part 2121, so that the other needle body 1 can slide forward from the turn stitch cavity 3.

[0062] As a sixth embodiment provided by this utility model, such as Figure 8As shown, there are two positioning abutment parts 211. Preferably, the two positioning abutment parts 211 are disposed on the front end 21 of the needle turning, and the two positioning abutment parts are staggered. The angle A between the line connecting the two positioning abutment parts 211 and the side wall of the needle turning spring 2 is 90°-110°, preferably 100°. The two positioning abutment parts 211 guide the other needle body 1, so that the other needle body 1 and one of the needle bodies 1 form an angle B. The angle B ranges from 90°-110°, preferably 100°. By abutting the two positioning abutment parts 211 disposed on the side wall of the front end 21 of the needle turning and the side wall of the needle body 1, the deformation of the needle turning spring 2 caused by the diagonal tension of the coil is prevented during the needle turning process. At the same time, the two positioning abutment parts 211 disposed on the needle turning spring 2 can also prevent deformation caused by the diagonal tension of the coil during the needle turning process. The abutment part 211 abuts against the side wall of another knitting needle body 1 to position the other knitting needle body 1.

Of course, for other special needle types, the above distance is not limited to ±0.9mm and can be set according to different needle types. When performing turn-over knitting, when the turn-over abutment part 212 is not set, it is applied to conventional knitting. At this time, the turn-over cavity 3 is larger. When the other knitting needle body 1 is inserted into one of the knitting needle bodies 1, the needle tongue of the other knitting needle body 1 is directly pushed open by the front end of the turn-over spring 2.

[0063] As the seventh embodiment provided by this utility model, such as Figure 9As shown, there is one positioning abutment part 211. Preferably, the positioning abutment part 211 is located on the lower edge of the side wall of the needle turning front end 21. By abutting the side wall of the needle turning spring 2 with the side wall of the needle body 1, the positioning abutment part 211 prevents the needle turning spring 2 from being deformed by the diagonal tension of the coil during the needle turning process. At the same time, the positioning abutment part 211 on the needle turning spring 2 can abut against the side wall of another needle body 1 to position the other needle body 1. The positioning abutment part 211 guides the other needle body 1 so that the other needle body 1 and one of the needle bodies 1 form an angle B. The angle B is in the range of 90°-110°, preferably 10°. When the outer arc surface of the hook of another needle body 1 is inserted into the inside of the turning hole cavity 3 at 0°, the distance between the outer arc surface of the other needle body 1 and the corner arc surface 11 of one of the needle bodies 1 is ±0.9mm, so as to ensure that the hook part of the other needle body 1 can hook the loop. Of course, for other special needle types, the above distance is not limited to ±0.9mm and can be set according to different needle types. When turning stitch knitting, when the turning abutment part 212 is not set, it is applied to regular knitting. At this time, the turning hole cavity 3 is larger. When the other needle body 1 is inserted into one of the needle bodies 1, the needle tongue of the other needle body 1 is directly pushed away by the front end of the turning spring 2.

[0064] As the eighth embodiment provided by this utility model, such as Figure 10 As shown, there is one positioning abutment 211. Preferably, the positioning abutment 211 is located on the upper edge of the side wall of the needle turning front end 21. By abutting the needle turning spring 2 on the side wall of the needle turning spring 2 against the side wall of the needle body 1, deformation of the needle turning spring 2 due to the diagonal tension of the loop is prevented during the needle turning process. At the same time, the positioning abutment 211 on the needle turning spring 2 can abut against the side wall of another needle body 1 to position the other needle body 1. The positioning abutment 211 guides the other needle body 1, so that the other needle body 1 can be positioned.

When the outer arc surface of the hook of the other knitting needle body 1 is inserted into the turn-over cavity 3, the distance between the outer arc surface of the other knitting needle body 1 and the corner arc surface 11 of one of the knitting needle bodies 1 is ±0.9mm, to ensure that the hook part of the other knitting needle body 1 can hook the loop. Of course, for other special needle types, the above distance is not limited to ±0.9mm and can be set according to different needle types during turn-over knitting. When the turn-over abutment part 212 is not provided, it is applied to conventional knitting. At this time, the turn-over cavity 3 is larger. When the other knitting needle body 1 is inserted into one of the knitting needle bodies 1, the needle tongue of the other knitting needle body 1 is directly pushed open by the front end of the turn-over spring 2.

[0065] As the ninth embodiment provided by this utility model, such as Figure 11 As shown, the positioning abutment part 211 is provided by a slotted bend (the direction of the bend is not limited, as long as the positioning abutment part 211 can be formed). The included angle A between the side wall of the positioning abutment part 211 and the edge of the side wall of the needle-turning spring 2 is 90°-110°, preferably 100°. By abutting against the side wall of the needle body 1, the positioning abutment part 211 supports the needle-turning spring 2 and prevents it from being deformed by the diagonal tension of the coil during the needle-turning knitting process. At the same time, the positioning abutment part 211 provided on the needle-turning spring 2 can abut against the side wall of another needle body 1, thus supporting the other needle body 1. One knitting needle body 1 is positioned, and the positioning abutment part 211 guides another knitting needle body 1, so that the other knitting needle body 1 and one of the knitting needle bodies 1 form an angle B. The range of angle B is the same as that of angle A, and the range of angle B is 90°-110°, preferably 100°. When the outer arc surface of the hook of the other knitting needle body 1 is inserted into the needle-turning cavity 3, the distance between the outer arc surface of the other knitting needle body 1 and the corner arc surface 11 of one of the knitting needle bodies 1 is ±0.9mm, so as to ensure that the hook part of the other knitting needle body 1 can hook the loop. Figure 19 As shown, in this embodiment, the shape of the positioning abutment part 211 can be a rectangle, rhombus, triangle, arc or other geometric shape. It is only necessary to ensure that the side of the positioning abutment part 211 that is used to contact another knitting needle body 1 is perpendicular to the needle flipping spring 2.

[0066] For the flip abutment part 212, when there is one flip abutment part 212, it can be set on the upper edge or lower edge of the flip needle spring 2 according to the needle type. When there are two flip abutment parts 212, the two flip abutment parts 212 are staggered and can be parallel to the side wall of the positioning abutment part 211. When no flip abutment part 212 is set, it can be applied to regular knitting.

[0067] As another embodiment of the flip-up abutment part 212 of this utility model, such as Figure 28 — Figure 30 As shown, the flip-up abutment part 212 is stamped and protrudes from the flip-up needle spring 2, which ensures the smooth opening of the needle tongue without sacrificing the volume of the flip-up needle receiving cavity of the flip-up needle spring 2. The specific position of the flip-up abutment part 212 can be adjusted appropriately according to actual needs during the production process.

[0068] As a further embodiment provided by this utility model, such as Figure 2 and Figure 3 As shown, the flipping needle spring 2 also includes a flat part 22 and a connecting part 23.
