Description

Technical Field

[0001] This utility model relates to the field of single-needle device technology, and in particular to a portable single-needle for mounting gear rollers. Background Technology

[0002] A geared roller sewing machine refers to a device that uses gears and rollers (rollers) for power transmission. Gear transmission transmits power through a set of gears, while rollers are commonly used to guide and support moving parts, and are generally used in precision machinery and automated production lines. A single-needle sewing machine typically refers to a device that operates using a single needle, commonly found in sewing machines, embroidery machines, etc., usually used for fine sewing work, suitable for applications requiring high precision and stability. Single-needle sewing machines are the most common type of industrial sewing machine, suitable for most common sewing tasks.

[0003] Gear roller sewing machines typically use a threaded locking design to secure the needle to the needle bar. This threaded connection firmly attaches the needle to the needle bar, preventing it from loosening or falling off during operation. The needle usually has a threaded hole at the bottom, and the needle bar also has a corresponding threaded section. The needle is secured by screwing it in, and a locking nut and similar locking device ensure its stability. This structure effectively prevents needle shifting and vibration during high-speed operation, ensuring accuracy and stability in the sewing process.

[0004] In existing technologies, the fixing method for sewing needles is mostly threaded locking. These fixing methods require a lot of time and effort to install, especially when frequent needle replacements are needed, which significantly increases the complexity of operation and causes inconvenience to operators. At the same time, traditional fixing methods will loosen and wear after long-term use, further affecting the stability and safety of the equipment. Therefore, a portable gear roller sewing needle mounting method is proposed to solve the above problems. Utility Model Content

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figure 1 , Figure 2 and Figure 4 This utility model provides an embodiment of a portable gear roller sewing machine single needle, including a base 1. The base 1 is a block-shaped basic component with a cuboid shape. It is made of a sturdy and moderately heavy metal material, such as aluminum alloy. While ensuring sufficient strength and stability, the base 1 effectively reduces the weight of the entire device, making it easy to carry and move. The top of the base 1 is fixedly connected to a body 2. The body 2 is a component with a specific mechanical structure and function. It is made of engineering plastic material, which has good insulation and wear resistance, and can effectively protect the internal precision mechanical structure from interference and damage from the external environment. The bottom of the body 2 is fixedly connected to a needle bar 3. The needle bar 3 is a slender cylindrical shape. It is made of high-strength alloy steel, which has extremely high hardness and toughness. It can withstand the impact and friction generated by frequent up-and-down movements during sewing, ensuring the structural integrity and service life of the needle bar 3. Its outer surface is finely processed and polished, with good straightness and surface smoothness, to reduce frictional resistance with other components and ensure the smooth movement of the needle bar 3.

[0031] A mounting mechanism is fixedly connected to the bottom of the needle bar 3. The mounting mechanism includes a connecting post 4, which is a slender cylindrical shape made of metal, such as carbon steel. A fixing ring 6 is fixedly connected to the outside of the connecting post 4. The fixing ring 6 is a ring-shaped metal component made of metal, such as carbon steel. A groove 10 is formed inside the fixing ring 6. The groove 10 is a rectangular groove structure to facilitate stable sliding movement of the limiting post 9 inside the groove 10, thereby achieving precise positioning and fixing of the needle 14. A hole 11 is formed inside the fixing ring 6. The hole 11 is a rectangular hole structure, providing a channel and space for the installation and connection of the limiting post 9. The top of the connecting post 4 is fixedly connected to the bottom of the needle bar 3. An anti-collision cotton 5 is fixedly connected to the upper part of the inside of the connecting post 4. 5. It can effectively absorb and buffer impact force, protect the needle 14 from damage, and extend the service life of the needle 14. The sliding post 7 is slidably connected inside the connecting post 4. The sliding post 7 is slender cylindrical in shape and is made of metal, such as carbon steel. One end of the sliding post 7 is fixedly connected to a pull ring 8. The pull ring 8 is an annular metal handle made of metal, such as carbon steel, which facilitates the operation of the operator when installing and replacing the needle 14. The other end of the pull ring 8 is fixedly connected to a limiting post 9. The limiting post 9 is slender cylindrical in shape and is made of metal, such as carbon steel. It can adjust the position of the limiting post 9 inside the groove 10, thereby realizing the installation and fixing operation of the needle 14. The external part of the limiting post 9 is slidably connected inside the groove 10, and the external part of the fixing ring 6 is slidably connected inside the fixing ring 6.

[0032] Reference Figure 1 , Figure 3 and Figure 4The mounting mechanism has a rotatable fixing component inside, which includes two nuts 13. Each nut 13 is a hexahedral block structure with internal threads, made of metal such as carbon steel. The nuts 13 and the connecting post 4 maintain a good fit, preventing jamming or disengagement. The nuts 13 move along the threads of the bolt 12, adjusting their position within the connecting post 4 to clamp and fix the needle 14, ensuring the normal operation of the fixing component. The nuts 13 are externally rotatably connected to the inside of the connecting post 4, and the bolt 12 is threadedly connected to the external threads of the nuts 13. The bolt 12 is integrally... It is shaped like a slender cylinder and is made of metal, such as carbon steel. The two bolts 12 are fixedly connected to the left and right sides of the connecting column 4 on the side closest to each other, i.e. the side furthest from the outside of the bolts 12. The connecting column 4 is slidably connected to a sewing needle 14. The sewing needle 14 is slender and needle-like in shape and is made of high-quality alloy steel. It has high hardness, high wear resistance and good toughness, which can meet the needs of sewing operations on various fabrics. The top of the sewing needle 14 is slidably connected to the bottom of the anti-collision cotton 5. The inside of the limiting column 9 is slidably connected to the outside of the sliding column 7, and the inside of the sewing needle 14 is slidably connected to the outside of the sewing needle 14.

[0033] Working principle: First, the needle 14 to be installed and fixed is slid into the internal hole of the connecting post 4. Anti-collision cotton 5 is also provided at the end of the hole in the connecting post 4 to prevent one end of the needle 14 from being bumped or squeezed and damaged. Then, the operator holds the pull ring 8 and applies force, causing the sliding post 7 to slide into the interior of the connecting post 4. When it slides through the interior of the fixing ring 6 on the other side of the connecting post 4, the pushing force is converted into a thrust, causing the sliding post 7 to rotate and drive the limiting post 9 to rotate. The limiting post 9 is then restricted by the groove 10 on the surface of the fixing ring 6, thus installing and fixing the needle 14. Next, the nuts 13 at both ends of the connecting post 4 are simultaneously rotated towards the center, so that the nuts 13 are locked by the bolts 12 at both ends of the connecting post 4, pressing the needle 14 into the middle of the interior of the connecting post 4, further strengthening the installation and fixing of the connecting post 4. Furthermore, the bottom of the needle 14 has a hole for easy needle threading.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
