Description

Technical Field

[0001] This invention relates to the field of textile machinery technology, and in particular to a rotary shuttle with unlimited speed, built-in ventilation, heat dissipation, and waste removal. Background Technology

[0002] With the continuous advancement of technological research and development, the efficiency of knitting machines, such as sewing machines, embroidery machines, quilting machines, and quilting stitch machines, is constantly improving, enabling them to provide beautiful, complex, and layered sewing or embroidery effects. A modern high-speed embroidery machine typically has over three hundred embroidery needles arranged side-by-side and performs programmed embroidery operations at a rate exceeding one thousand times per minute, thus significantly increasing the production capacity of modern high-speed embroidery machines.

[0003] In high-speed production processes, such as embroidery machines, the sewing needle moves up and down at high speed. The rotary shuttle below it, including components such as the shuttle bed, shuttle frame, bobbin, and shuttle case, also rotates synchronously at high speed, thereby achieving high-precision and complex embroidery operations. In particular, the shuttle frame and shuttle bed rotate synchronously at high speed. Due to their compact structure and ease of disassembly and assembly, the lock frame and shuttle bed are connected by a mechanism of convex strips and limiting grooves. The rotation between the shuttle frame and shuttle bed is a sliding friction structure. Under current conditions, even if the processing accuracy is improved and the material is modified, when the lock frame is running at high speed (the shuttle bed is relatively stationary), a large amount of heat will be generated between the two. Under long-term operation, this will result in severe heat generation and wear. Therefore, the existing rotary shuttle mechanism has the problems of not being able to rotate at high speed and being prone to wear and damage.

[0004] Meanwhile, when equipment such as sewing machines, embroidery machines, quilting machines, and quilting sewing machines are running, a large amount of fine fibers and dust are generated. When lubricating oil is added appropriately to the rotary hook mechanism, these fine fibers and dust will adhere to the moving parts. This not only hinders heat dissipation but also makes the operation less smooth. With prolonged use, the accumulation of fibers and dust will greatly increase the resistance of the equipment's operation and reduce the accuracy of the work. It is very easy for needles or threads to break. In severe cases, the equipment may jam and there is a fire hazard. Summary of the Invention

[0005] The purpose of this invention is to provide a rotary hook with unlimited speed, built-in ventilation, heat dissipation and sewage discharge. Through the design of efficient heat dissipation and sewage discharge, the rotary hook can adapt to high-speed operation, improve the service life of the rotary hook and reduce maintenance and replacement costs.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows: A rotary shuttle with unlimited speed, built-in ventilation, heat dissipation, and sewage discharge includes a shuttle bed and a shuttle frame. The shuttle frame can be inserted into the interior of the shuttle bed. The outer wall of the shuttle frame is provided with a guide rail, and the inner wall of the shuttle bed is provided with a rail groove. The rail groove can accommodate the guide rail and allow the shuttle frame and shuttle bed to rotate under the restriction of the guide rail and the rail groove. The guide rail is provided with multiple through straight holes, and the shuttle bed is provided with multiple through air guide holes at the corresponding positions of the rail groove. The straight holes and air guide holes can be connected to each other to form an air guide channel.

[0007] Furthermore, the diameter of the air guide hole is larger than the diameter of the straight hole.

[0008] Furthermore, the spacing between the air guide holes is greater than or equal to the spacing between the straight holes.

[0009] Furthermore, the air guide hole has a funnel-shaped opening structure.

[0010] Furthermore, the outer end of the air guide hole is inclined in the direction of the shuttle bed's rotation and forward movement.

[0011] Furthermore, the outer wall of the shuttle bed is provided with a crescent plate and a small blade. The crescent plate and the small blade are installed and fixed to the outer wall of the shuttle bed by a screw structure. The top of the crescent plate is provided with a flap strip. The flap strip is arranged on the upper edge of the guide rail. The crescent plate is provided with a second air guide hole corresponding to the air guide hole. The small blade is provided with a third air guide hole corresponding to the air guide hole.

[0012] Furthermore, the shuttle bed has a transverse groove at the opening of the air guide hole corresponding to the small blade and / or crescent blade. The transverse groove can connect the corresponding air guide hole laterally and form a connected ventilation channel.

[0013] Furthermore, the shuttle bed has straight grooves at the openings of the air guide holes corresponding to the small blades and / or crescent blades, and the straight grooves can connect the corresponding air guide holes longitudinally.

[0014] Furthermore, the straight groove is arranged at an angle, with its upper end inclined in the direction of the shuttle bed's rotation and forward movement.

[0015] Furthermore, the shuttle bed is provided with light-reducing holes.

[0016] Compared with existing technologies, this solution has the following advantages: This solution presents an innovative rotary shuttle with unlimited speed, integrated ventilation, heat dissipation, and waste removal. It features multiple through-holes on the guide rails of the shuttle frame and multiple through-holes in the shuttle bed's rail grooves. This internal and external air duct structure enables ventilation, heat dissipation, and waste removal. Therefore, during high-speed rotation of the shuttle bed relative to the shuttle frame, air is rapidly transported from the inside to the outside through the through-holes and air ducts, utilizing centrifugal force. This air is introduced between the shuttle bed and the shuttle frame, particularly into the rail grooves and guide rails. Firstly, this removes heat, achieving cooling. Secondly, it overcomes the problem of dust accumulation in traditional rotary shuttles, allowing the circulating air to carry away dust and fine fibers. Furthermore, an air film structure is formed between the rail grooves and guide rails, significantly reducing frictional resistance between the shuttle bed and the shuttle frame and improving rotational balance. This solution aims to develop a high-speed, long-life, and low-maintenance rotary shuttle mechanism. In practical use, adding a certain amount of low-viscosity lubricating oil to the straight holes or air guide holes creates excellent lubrication in the rail groove and guide rail. Traditional closed rotary shuttle mechanisms without holes are not only inconvenient to add lubricating oil, but also require lubrication at every angle when the entire guide rail and rail groove need lubrication, making the operation extremely cumbersome. This solution's rotary shuttle only requires lubricating oil to be added to one or a few air guide holes. During operation, the lubricating oil can quickly enter each air guide hole, straight hole, rail groove, and guide rail, and can even be added without stopping the machine, thus greatly improving the equipment's efficiency. The rotary hook mechanism operating with this solution can adapt to sewing and embroidery operations exceeding 10,000 revolutions per minute in knitting fields such as sewing machines, embroidery machines, quilting machines, and quilting sewing machines. Compared with traditional rotary hooks, it can greatly reduce replacement and maintenance costs, thus serving modern large-scale high-speed textile equipment and having great significance for promotion.

[0023] refer to Figures 1 to 5 A rotary shuttle with unlimited speed, self-ventilation, heat dissipation, and sewage discharge includes a shuttle bed 1 and a shuttle frame 2. The shuttle frame 2 is used to house the bobbin and the bobbin case. The shuttle frame 1 can be inserted into the shuttle bed 1. In actual operation, the shuttle frame 2 is restricted by the rotary shuttle mounting frame, while the shuttle bed 1 rotates at high speed driven by the rotary shuttle shaft. In actual work, with each rotation of the shuttle bed 1, the bobbin thread contained in the bobbin is conveyed, and through cooperation with the sewing needle, a single stitch or embroidery operation is achieved. Therefore, to achieve higher sewing efficiency, the rotation speed of the shuttle bed 1 must be increased.

[0024] Because the shuttle bed 1 and shuttle frame 2 have a compact structure and irregular arrangement, it is not possible to set rolling friction parts such as bearings. In order to achieve the functions of limiting and rotating, the outer wall of the shuttle frame 2 is provided with a guide rail 21, and the inner wall of the shuttle bed 1 is provided with a rail groove 11. The rail groove 11 can accommodate the guide rail 21 and allow the shuttle frame 2 and the shuttle bed 1 to rotate under the restriction of the guide rail 21 and the rail groove 11. Due to the existence of the installation structure, the guide rail 21 and the rail groove 11 are not in a complete circle state, and there are gaps in some of them. However, the existence of gaps does not affect their mutual rotation operation. In order to achieve ventilation, heat dissipation and sewage discharge functions, multiple through straight holes 22 are provided on the guide rail 21 of the shuttle frame 2. The straight holes 22 are perpendicular to the center of the shuttle frame 2 and are arranged in a central array. The diameter of the holes is less than or equal to 0.9 mm, and more than 48 holes can be arranged in one circle.

[0025] The outer wall of the shuttle bed 1 is provided with a crescent plate 12 and a small blade 13. Both the crescent plate 12 and the small blade 13 are installed and fixed to the outer wall of the shuttle bed 1 by screws. The crescent plate 12 is mainly used to install and restrict the shuttle frame 2. Its top is provided with a flap bar 121. After installation, the flap bar 121 will fasten the upper edge of the guide rail 21 and restrict the entire shuttle frame 2 inside the shuttle bed 1. The small blade 13 is a thin sheet structure, usually made of stainless steel. The small blade 13 is provided with multiple protrusions and pointed structures to guide the bottom thread and realize embroidery and sewing operations.

[0026] The shuttle bed 1 has multiple through air guide holes 10 at the corresponding positions of the rail groove 11. The air guide holes 10 are vertically pointed to the center of the shuttle bed 1 and are arranged in a central array. After installation, the straight holes 21 and the air guide holes 10 are on the same plane. Therefore, the straight holes 21 and the air guide holes 10 on the shuttle frame 2 can be connected to form an air guide channel. When the shuttle bed 1 rotates at high speed, the air inside the shuttle frame 2 can be guided into the outside of the shuttle bed 1 through the straight holes 21 and the air guide holes 10 under the action of centrifugal force.

[0027] The diameter of the air guide hole 10 is greater than or equal to the diameter of the straight hole 21, and its diameter is usually around 1.3 mm. At the same time, the arrangement spacing of the air guide hole 10 is greater than or equal to the arrangement spacing of the straight hole 21. This can improve the air guiding efficiency and allow air to pass through the straight hole 21 better, thereby improving the heat dissipation and sewage discharge efficiency.

[0028] In some embodiments, the air guide hole 10 is in a trumpet-shaped opening state, that is, the diameter of the opening at the inner wall is smaller and the diameter at the outer wall is larger, so that more air can be guided into the interior of the air guide hole 10, thereby improving the speed and efficiency of air flow.

[0029] In some embodiments, the outer end of the air guide hole 10 is inclined in the direction of the shuttle bed 1 rotating forward, thereby improving the air guiding efficiency.

[0030] In order to achieve complete and efficient ventilation, heat dissipation and sewage discharge, a second air guide hole 122 is arranged on the crescent plate 12. The arrangement position and structure of the second air guide hole 122 correspond one-to-one with the air guide hole 10. Therefore, a complete air guide channel that runs through the inside and outside can be formed here through the second air guide hole 122, the air guide hole 10 and the straight hole 21. A third air guide hole 131 is arranged on the small blade 13. The arrangement of the third air guide hole 131 corresponds one-to-one with the air guide hole 10. Therefore, a complete air guide channel that runs through the inside and outside can be formed here through the third air guide hole 131, the air guide hole 10 and the straight hole 21. The shuttle bed 1 has transverse grooves 14 within the corresponding range of the crescent blades 12 and / or the small blades 13, and at the corresponding openings of the air guide holes 10. The width of the transverse grooves 14 is larger than the diameter of the air guide holes 10. Straight grooves 15 are also arranged at the openings of these air guide holes 10, and these straight grooves 15 are arranged at an angle. Therefore, through this structure, the transverse grooves 14 connect these air guide holes 10 laterally, and the transverse grooves 14 are arranged as airflow channels penetrating the ventilation holes 10. These channels can also hold a certain amount of lubricating oil, serving to store, distribute, and lubricate the oil. Meanwhile, the straight groove 15 connects the corresponding horizontal groove 14 and the upper and lower ends of the air guide hole 10 to the outside, so external air can enter through the upper and lower ends of the straight groove 15 and form a smooth airflow channel through the horizontal groove 14 and the air guide hole 10. Especially when the shuttle bed 1 rotates at high speed, it can inject a large amount of air pressure into the guide rail 21 and the rail groove 11, which can solve the problem of a large amount of heat accumulation in the guide rail 21 and the rail groove 11 due to dry friction. It can also remove the dust and fine fibers accumulated between the small blade 13 and the shuttle bed 1. Therefore, the entire rotary shuttle mechanism will operate more smoothly and can adapt to high-speed operation of 10,000 revolutions per minute, thereby greatly improving the efficiency of the whole machine.

[0031] In some embodiments, the straight groove 15 is arranged at an inclination, with its upper end inclined in the direction of the shuttle bed 1's rotation. Therefore, when the shuttle bed 1 rotates at high speed, its upper end is the windward side, and air is introduced into the straight groove 15 and the horizontal groove 14 by positive pressure. At the same time, at the lower end of the straight groove 15, which is on the leeward side, negative pressure is generated, which can accelerate the exhaust of air, thereby forming a good air circulation channel and greatly improving the efficiency of cooling, heat dissipation and sewage discharge.

[0032] In some embodiments, the guide rail 21 and the rail groove 11 may be made of nanomaterials, tungsten steel or ceramic materials, or a combination of nanomaterials, tungsten steel or ceramic materials, thereby increasing their wear resistance and heat resistance, and ultimately improving their service life and reducing maintenance costs.

[0033] refer to Figure 6 In some embodiments, the bottom of the shuttle bed 1 is connected to the rotary shuttle shaft via a clamp 16 and bolts 17. Compared with the traditional three-jaw fixing structure, this greatly reduces the installation difficulty of the rotary shuttle, allowing the operator to install and fix it flexibly and conveniently. Installation can be performed at any angle. In order to reduce the moment of inertia of the shuttle bed 1 and reduce its weight, multiple weight-reducing holes 18 are provided on the shuttle bed 1. Therefore, through this structure, the weight of the shuttle bed 1 can be reduced and its rotational balance can be improved, thereby adapting to high-speed operation and ultimately improving the efficiency of the whole machine.

[0034] In summary, this solution presents an infinite-speed rotary shuttle with integrated ventilation, heat dissipation, and waste removal. It innovatively incorporates multiple through-holes 22 on the guide rail 21 of the shuttle frame 2 and multiple through-holes 10 in the rail groove 11 of the shuttle bed 1. This internal and external through-hole structure enables ventilation, heat dissipation, and waste removal. Therefore, during high-speed rotation of the shuttle bed 1 relative to the shuttle frame 2, external air is introduced between the shuttle bed 1 and the shuttle frame 2 through the air holes 10, and then transported to the interior of the shuttle frame 2 through the through-holes 21. This serves two purposes: firstly, it removes heat, achieving cooling; secondly, it overcomes the problem of dust accumulation in traditional rotary shuttles by allowing airflow to carry away dust and fine fibers; and thirdly, it forms an air film structure between the rail groove 11 and the guide rail 21, significantly reducing frictional resistance between the shuttle bed and the shuttle frame and improving rotational balance. Therefore, compared to traditional dry-friction rotary shuttles, it can achieve a working efficiency of up to 10,000 revolutions per minute. This solution aims to develop a high-speed, long-life, and low-maintenance rotary shuttle mechanism. In practical use, adding a certain amount of low-viscosity lubricating oil at the air guide hole 10 can create good lubrication at the rail groove 11 and guide rail 21. Traditional closed rotary shuttle mechanisms without holes are not only inconvenient to add lubricating oil, but also require lubrication at every angle when the entire guide rail 11 and rail groove 21 need lubrication, making the operation extremely cumbersome. The rotary shuttle mechanism of this solution only requires adding lubricating oil at one or a few air guide holes 10. During its operation, the lubricating oil can quickly enter each air guide hole 10, straight hole 22, rail groove 11, and guide rail 21. It can even add lubricating oil without stopping the machine, thus greatly improving the efficiency of the equipment.
