Description

Technical Field

[0001] This utility model relates to the field of embroidery equipment technology, and in particular to a conical embroidery needle for preventing skipped stitches. Background Technology

[0002] Currently, common embroidery needles on the market have many problems in actual use. On the one hand, the needle tip angle design of ordinary embroidery needles is unreasonable. When piercing the fabric, the fabric fibers are prone to getting tangled around the needle, causing the needle to encounter greater resistance when passing through the fabric, resulting in skipped stitches. This seriously affects the integrity and aesthetics of the embroidery pattern. On the other hand, the existing needles do not have enough friction between them and the fabric. During the embroidery process, the fabric is prone to slipping or shifting, especially during high-speed embroidery or complex pattern embroidery. This is more obvious, leading to inaccurate thread positioning and pattern deviation. In addition, the needle body structure of some needles is poorly designed. During long-term use, fabric fibers are prone to getting tangled around the needle body, affecting the stability of the needle body and further increasing the risk of skipped stitches. At the same time, the connection between traditional embroidery needles and embroidery equipment is not secure enough. When the equipment is running at high speed, the needle may loosen, causing the movement trajectory to deviate, which can also cause skipped stitches. Therefore, we have launched a tapered embroidery needle to prevent skipped stitches. Utility Model Content

[0003] The main purpose of this invention is to provide a tapered embroidery needle that prevents skipped stitches, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A tapered embroidery needle for preventing skipped stitches includes a needle handle, a needle body device fixedly connected to the left end of the needle handle, a needle head device fixedly connected to the left end of the needle body device, and a plurality of anti-slip rings fixedly connected to the outer surface of the needle handle.

[0006] The needle body device includes a needle body body, the outer surface of which is provided with L-shaped grooves and a plurality of conical slots. The needle body body is fixedly connected to the right end of the first needle tip section.

[0007] Preferably, the needle device includes a first needle section and a second needle section. The first needle section is located at the right end of the second needle section and is integrally formed. The surface of the second needle section and the surface of the first needle section are both curved. A threading groove is opened on the left side of the surface of the second needle section. Several resistance grooves are engraved on the rear side of the second needle section. Several resistance grooves are engraved on the front edge and the rear edge of the second needle section. The first needle section is fixedly connected to the left end of the needle body.

[0008] Preferably, a plurality of the anti-detachment rings are distributed at equal intervals along the axial direction of the needle handle, and the distance between two adjacent anti-detachment rings is 1 mm.

[0009] Preferably, a plurality of L-shaped grooves are arranged around the outer surface of the needle body, and the depth of the L-shaped grooves is 0.3 mm.

[0010] Preferably, the curved surface gradually narrows from the right end of the first needle tip segment to the left end of the second needle tip segment, and the radius of curvature of the curved surface varies from 0.5 to 1.5 mm.

[0011] Preferably, the plurality of resistance barbed grooves one and the plurality of resistance barbed grooves two are all triangular in shape, and the depth of the plurality of resistance barbed grooves one and the plurality of resistance barbed grooves two is 0.08mm, and the plurality of resistance barbed grooves one and the plurality of resistance barbed grooves two are all inclined at 30°.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In this invention, the curved surface formed by the first and second needle segments in the needle device gradually narrows from right to left, with the radius of curvature varying between 0.5 and 1.5 mm. This design optimizes the needle tip angle, guiding the fabric fibers to disperse to both sides when piercing the fabric, effectively reducing the situation of fibers entangled in the needle, reducing the resistance of the needle passing through the fabric, reducing skipped stitches, and ensuring the integrity and aesthetics of the embroidery pattern.

[0014] In this invention, the triangular resistance grooves 1 and 2, with a depth of 0.08 mm and an inclination of 30°, are provided on the edge and rear side of the second needle tip. These significantly increase the friction between the needle tip and the fabric. During the piercing and pulling out of the fabric, the needle tip can better grasp the fabric fibers, prevent the fabric from sliding or shifting, ensure the precise positioning of the embroidery thread during the embroidery process, and enable complex pattern embroidery to have smooth lines and even stitches.

[0015] In this invention, an L-shaped notch with a depth of 0.3mm and several conical grooves are arranged around the outer surface of the needle body. The L-shaped notch can slightly cut the fabric fibers, reducing the fiber entanglement of the needle body, while the conical grooves disperse the pressure of the fabric on the needle body. The two work together to make the needle body move more stably through the fabric, reduce the risk of skipped stitches caused by the shaking of the needle body, and improve the stability of the embroidery process.

[0016] In this invention, anti-slip rings with equal spacing and an adjacent distance of 1mm are distributed on the outer surface of the needle handle and closely cooperate with the clamping parts of the embroidery equipment to ensure that the needle is securely installed on the equipment. When the equipment is running at high speed, the needle can maintain the correct movement trajectory and avoid the problem of skipped stitches caused by loose needles, thus providing a reliable guarantee for high-quality embroidery.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] Please see Figure 1-4 This utility model provides a technical solution:

[0026] A tapered embroidery needle for preventing skipped stitches includes a needle handle 3, a needle body device 2 fixedly connected to the left end of the needle handle 3, a needle head device 1 fixedly connected to the left end of the needle body device 2, and a plurality of anti-slip rings 4 fixedly connected to the outer surface of the needle handle 3.

[0027] Several anti-detachment rings 4 are evenly distributed along the axial direction of the needle handle 3, and the distance between two adjacent anti-detachment rings 4 is 1mm.

[0028] In this embodiment, the needle body device 2 includes a needle body body 21. The outer surface of the needle body body 21 is provided with L-shaped grooves 22. The outer surface of the needle body body 21 is provided with a plurality of conical grooves 23. The needle body body 21 is fixedly connected to the right end of the first needle tip section 11. The plurality of L-shaped grooves 22 are arranged around the outer surface of the needle body body 21, and the depth of the L-shaped grooves 22 is 0.3mm.

[0029] Through the above scheme: In the needle body device 2, the outer surface of the needle body 21 is surrounded by L-shaped grooves 22 with a depth of 0.3mm and several conical grooves 23. During the embroidery process, the L-shaped grooves 22 can slightly cut the fabric fibers, reducing the situation of fibers entangled in the needle body, while the conical grooves 23 disperse the pressure of the fabric on the needle body. The two work together to enable the needle body to pass through the fabric more stably, reducing the risk of skipped stitches caused by the shaking of the needle body. At the same time, this structural design can also effectively reduce the friction between the fabric and the needle body, making the needle piercing process smoother, reducing the resistance during the embroidery process, and improving the embroidery efficiency.

[0030] In this embodiment, the needle device 1 includes a first needle section 11 and a second needle section 12. The first needle section 11 is located at the right end of the second needle section 12 and is integrally formed. The surface of the second needle section 12 and the surface of the first needle section 11 are both curved surfaces 13. A threading groove 15 is opened on the left side of the surface of the second needle section 12. Several resistance grooves 16 are engraved on the rear side of the second needle section 12. Several resistance grooves 14 are engraved on the front edge and the rear edge of the second needle section 12. The head section 11 is fixedly connected to the left end of the needle body 21. The curved surface 13 gradually narrows from the right end of the first needle head section 11 to the left end of the second needle head section 12, and the radius of curvature of the curved surface 13 varies from 0.5 to 1.5 mm. Several resistance puncture grooves 14 and several resistance puncture grooves 16 are triangular in shape, and the puncture depth of several resistance puncture grooves 14 and several resistance puncture grooves 16 is 0.08 mm. Several resistance puncture grooves 14 and several resistance puncture grooves 16 are inclined at 30°.

[0031] Through the above scheme: In the needle device 1, the first needle section 11 and the second needle section 12 are integrally formed. The curved surface 13 formed by their surfaces gradually narrows from the right end of the first needle section 11 to the left end of the second needle section 12, with the radius of curvature varying from 0.5 to 1.5 mm. This gradually narrowing curved surface 13 design optimizes the needle tip angle, guiding the fabric fibers to disperse to both sides when piercing the fabric, reducing fiber entanglement. The thread groove 15 on the left side of the surface of the second needle section 12 is used to fix the embroidery thread. To ensure the stability of the embroidery thread, the second needle section 12 features triangular-shaped resistance grooves 14 and 16 with a depth of 0.08mm and a 30° inclination on its edge and back side. These grooves increase the friction between the needle and the fabric, allowing the needle to better grip the fabric fibers during piercing and withdrawal, preventing the fabric from sliding or shifting. The synergistic effect of these structures effectively reduces the probability of skipped stitches, ensuring precise thread positioning during embroidery, resulting in smooth lines and even stitches in the embroidery pattern, and significantly improving the aesthetics and quality of the finished embroidery.

[0032] It should be noted that this utility model is a conical embroidery needle for preventing skipped stitches. During use, the needle device 1, as a key part that directly contacts the fabric, plays a crucial role in preventing skipped stitches due to its structural design. The needle device 1 includes a first needle section 11 and a second needle section 12, which are integrally formed. Their surfaces together form a curved surface 13. The curved surface 13 gradually narrows from the right end of the first needle section 11 to the left end of the second needle section 12, with a radius of curvature ranging from 0.5 to 1.5 mm. This gradually narrowing curved surface 13 design optimizes the needle tip angle, ensuring that the needle can pierce the fabric more effectively. This design allows for smoother fiber penetration, reducing fabric resistance and pulling on the needle. The second needle section 12 has several triangular resistance grooves 14 engraved on both its front and rear edges, and several triangular resistance grooves 16 engraved on its rear side. The grooves are 0.08mm deep and all angled at 30°. These resistance grooves increase the friction between the needle and the fabric. During the needle's piercing and withdrawal process, the resistance grooves better grip the fabric fibers, preventing the fabric from slipping or shifting during needle movement, further reducing skipped stitches. For example, when the needle is withdrawn upwards... The friction between the resistance groove 16 and the fabric fibers helps stabilize the fabric and prevent skipped stitches caused by fabric looseness. The needle body device 2 also plays an important role in preventing skipped stitches. The outer surface of the needle body 21 features L-shaped notches 22 surrounding the needle body 21 with a depth of 0.3 mm4, as well as several conical grooves 23. These structural designs alter the force distribution when the needle body contacts the fabric. The L-shaped notches 22 can cut the fabric fibers to a certain extent, reducing fiber entanglement with the needle body, while the conical grooves 23 help disperse the pressure of the fabric on the needle body, allowing the needle body to... To ensure more stable needle movement through the fabric and reduce the risk of skipped needles due to needle body wobbling, several anti-slip rings 43, evenly distributed along the axial direction and with an adjacent distance of 1-3mm, are fixedly connected to the outer surface of the needle handle 3. This ensures the stable installation of the needle on the embroidery equipment. Stable installation ensures that the needle maintains the correct movement trajectory during high-speed piercing and avoids skipped needles caused by needle loosening. When the embroidery equipment drives the needle to move at high speed, the anti-slip rings 4 cooperate closely with the clamping parts of the equipment to provide reliable fixing force, enabling the needle to accurately pierce the fabric according to the designed path.
