Description

Technical Field

[0001] The utility model belongs to the technical field of knitting needle production, in particular to a cut-foot needle. Background Art

[0002] A knitting needle is a major loop-forming component on a knitting machine. It is made of steel wire or steel strip through mechanical processing and is used to weave yarn into coils and connect the coils into knitted fabrics. The improvement of knitting needles has promoted the development of knitting machines. Humans first used knitting needles for manual knitting. Later, crochet needles, latch needles, groove needles, double-headed latch needles, etc. were invented, which opened up new avenues for the development of knitting machines. Publication No.: CN217678011U discloses a high-stability knitting needle, which includes a needle bar, a needle hook formed thereon, and a needle latch for closing the needle hook. A needle transfer groove is provided on one side of the needle bar, and the bottom edge of the needle transfer groove extends to both sides to form an arc-shaped edge. The groove forms a long slit and a short slit along the inner side wall of the needle bar, the long slit is located on the inner side wall of the needle bar near the needle hook, and the short slit is located on the inner side wall of the needle bar near the stitch. The needle hook includes a first needle hook and a second needle hook, and the second needle hook is provided with a rotating mechanism that enables the first needle hook to rotate on the second needle hook. The turning needle groove is used as the turning needle, and the bottom edge of the turning needle groove forms an arc-shaped edge, which increases the knitting density of the wool and the knitting range is wider, which is conducive to improving the stability of knitting. The rotating mechanism adjusts the relative position of the first needle hook and the second needle hook, which is convenient for knitting wool of different thicknesses and improves the adaptability of the knitting needle.

[0003] However, there are some problems with the existing technology: currently, traditional knitting needles are produced with single legs, and the leg type is required. When customers need knitting needles of different lengths, manufacturers need to switch machines according to the knitting needles of different leg types during the production process. However, it is easy to become unstable when the machine is switched, and it is difficult to use it normally. Therefore, it is not conducive to matching the quantity during production. Different leg types need to be used in combination, and one leg type cannot be sold separately. It is difficult to meet the needs of different customers. Therefore, we propose a cut-leg needle.

DETAILED DESCRIPTION

[0023] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0024] like Figures 1 to 3 As shown, an embodiment of the present invention provides a pin cutting needle, comprising: a pin cutting needle body, the pin cutting needle body being integrally formed by a head end 1, a pre-cutting portion 2, and a tail end 3, the pre-cutting portion 2 being located between the head end 1 and the tail end 3, the pre-cutting portion 2 comprising a first pin 201 and a second pin 202, for use in cutting by the pin cutting needle body;

[0025] Traditional knitting needles are single-legged needles when they are punched out. They are punched according to the leg type required. When customers need knitting needles of different lengths, manufacturers need to switch machines according to the different leg types during the production process. However, it is easy for the machine to become unstable and unable to be used normally when switching. Therefore, it is not conducive to matching quantities during production. Different leg types need to be used in combination, and one leg type cannot be sold separately, making it difficult to meet the needs of different customers.

[0026] Specifically, such as Figure 1 and Figure 2As shown, a first stitch 201 and a second stitch 202 are provided between the head end 1 and the tail end 3, so that production can be performed at one time during the production process. After the customer buys the needle, the customer can cut off the excess stitches according to his or her own needs when using the needle, thereby not only improving the applicability of the knitting needles, but also allowing different customers to cut the needles themselves according to the type of needles they need, avoiding mismatches in use, and unifying the consistency of the knitting needles. In production, some processes no longer require frequent machine switching, thereby improving processing speed.

[0027] Furthermore, a first crossbar 204 is provided between the first pin 201 and the head end 1. The upper surface level of the first crossbar 204 is lower than the upper surface level of the first pin 201 and the head end 1, so as to form a first notch 203. The angles on both sides of the inner wall of the first notch 203 form a first tangent point 5 and a second tangent point 7.

[0028] Specifically, such as Figure 2 As shown, the first cross bar 204 serves as a connection point, which is convenient for cutting the two ends, and at the same time serves as the opening and closing of the needle mouth during the knitting process, so as to facilitate the padding of the yarn and the stringing of the old coils to form new coils, which is crucial for the knitting of knitted fabrics. The first tangent point 5 and the second tangent point 7 formed in the first recess 203 can be used as positioning points during the cutting process. During the production process, the distance between the head end 1 and the first tangent point 5 or the second tangent point 7 is measured in advance, so that when knitting needles of different lengths are needed in the future, quick cutting can be performed to improve work efficiency.

[0029] Furthermore, the inclination angle of the second tangent point 7 is greater than the inclination angle of the first tangent point 5;

[0030] Specifically, such as Figure 2 As shown, the thickness of the first stitch 201 is greater than the head end 1, so the inclination angle of the second tangent point 7 and the first tangent point 5. Different materials and thicknesses may require different cutting strategies. For example, for thicker materials, a larger cutting angle may be required to ensure the full penetration capability of the cutting equipment. Therefore, the inclination angle at the connection between the first stitch 201 and the first cross bar 204 is increased, which can better cut off excess stitches to improve the cutting effect.

[0031] Furthermore, a long rod 206 is provided between the second pin 202 and the first pin 201. The upper surface level of the long rod 206 is lower than the upper surface level of the first pin 201 and the head end 1, so as to form a second notch 207. The angle between the inner walls of the second notch 207 forms a third tangent point 8. A second crossbar 210 is provided at one end of the second pin 202. The upper surface level of the second crossbar 210 is lower than the upper surface level of the second pin 202 and the tail end 3, so as to form a third notch 208. The angle between the inner walls of the third notch 208 forms a fourth tangent point 6.

[0032] Specifically, such as Figure 2 As shown, the functions of the second notch 207 and the third notch 208 are the same as those of the first notch 203, but the angles of the third tangent point 8 and the fourth tangent point 6 are different from those of the first tangent point 5 and the second tangent point 7. They need to be designed according to the thickness of the knitted surface before production so that the knitting needles can cut them after production. It should be noted that the functions of the long rod 206 and the second cross bar 210 are the same as those of the first cross bar 204.

[0033] Furthermore, the upper surface of the long rod 206 is provided with protrusions 209, and the protrusions 209 are arranged at equal intervals;

[0034] Specifically, such as Figure 2 and Figure 3 As shown, the spacing between the multiple groups of protrusions 209 can be set to 1 mm, so that when cutting, the length can be measured according to the number of protrusions 209, so as to better cut out knitting needles of ideal length, thereby improving practicality.

[0035] Furthermore, a first bayonet 205 is provided at the lower end of the connection between the first pin 201, the long rod 206 and the first crossbar 204, and a second bayonet 211 is provided at the lower end of the connection between the second pin 202, the long rod 206 and the second crossbar 210. The first bayonet 205 and the second bayonet 211 are both wide on the outside and narrow on the inside.

[0036] Specifically, such as Figure 2 As shown, the first bayonet 205 and the second bayonet 211 are both configured to be wide on the outside and narrow on the inside, so that when docking with the knitting machine, as the card point of the knitting machine enters deeper into the first bayonet 205 or the second bayonet 211, the firmness can be improved. The knitting machine can be quickly installed on the knitting machine through the first bayonet 205 and the second bayonet 211, which improves the efficiency of needle installation, reduces the labor intensity of the operator, and reduces the needle installation time, thereby improving the operating efficiency of the knitting machine.

[0037] Furthermore, there are two groups of bumps 4 on the lower surface of the head end 1, and the two groups of bumps 4 are different in size;

[0038] Specifically, as shown in the figure, the bumps 4 on the surface of the head end 1 are usually used to form a three-dimensional effect on the fabric surface in the knitting process, that is, a raised pattern or texture. The bumps 4 can help form a specific pattern or structure on the surface of the knitted fabric, thereby increasing the aesthetics and texture of the fabric.

[0039] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
