Description

Technical Field

[0001] The utility model relates to the technical field of rotary shuttles, and particularly relates to a heat conduction structure capable of keeping the rotary shuttle at a low temperature. Background Technique

[0002] The rotary shuttle is an important component in a sewing machine and mainly undertakes the functions of: threading, mixing threads, unthreading, winding threads, and locking threads in the sewing machine. The rotary shuttle usually consists of a shuttle bed, a rotary shuttle leather, a rotary shuttle plate, a shuttle frame, etc. Among them, the shuttle frame is held by the sewing machine positioning hook and does not rotate, while the shuttle bed rotates relative to the shuttle frame. In specific work, for each up and down reciprocating movement of the sewing machine needle, the shuttle bed needs to rotate two turns. The shuttle body is the main part of the rotary shuttle, usually rectangular or square in shape, and there are shuttle wings on both sides for fixing the position.

[0003] The working principle of the rotary shuttle mainly depends on the rotational movement of the shuttle wheel, which makes the shuttle body swing back and forth. In this process, the yarn is transmitted through the threading holes in the shuttle body, and through the specific actions of the rotary shuttle, the yarn is interwoven in the fabric to form the warp and weft of the textile.

[0004] Therefore, the normal operation of the rotary shuttle is the premise for the operation of the sewing machine and is crucial for ensuring the sewing quality. The rotary shuttle is an indispensable part of the sewing machine and realizes the important function of completing sewing.

[0005] In high-speed industrial sewing machines, the sewing needle generally moves up and down reciprocally at a speed of about 3,500 stitches per minute, while the shuttle bed rotates at a high speed of about 7,000 revolutions per minute relative to the shuttle frame. With the continuous improvement of the sewing processing efficiency in the market, the required rotational speed of the rotary shuttle is getting faster and faster. Currently, during the high-speed production process of the sewing machine, the sewing needle moves up and down reciprocally at a high speed, and the rotary shuttle arranged below it, including components such as the shuttle bed, shuttle frame, bobbin core, and shuttle shell, also rotates synchronously at a high speed correspondingly, so as to realize high-precision and complex sewing operations. Currently, the slide rails on the rotary shuttle are all made of metal or polymer materials. When the rotational speed of the rotary shuttle is too high, extremely high heat will be generated on the slide rails, resulting in thermal expansion and contraction, aggravating the wear of the slide rails, and reducing the service life of the rotary shuttle. The existing common solution is to spray lubricating oil to reduce the temperature rise of the slide rails, but spraying lubricating oil will cause pollution to the fabric. In addition, when using polymer materials to make the slide rails, although the polymer materials can delay and inhibit the temperature rise in a short time, under long-term and high-intensity work, the effect of delaying and inhibiting the temperature rise will gradually fail, and the temperature rise problem still cannot be solved.

[0006] A rotating shuttle with excellent heat dissipation, with the publication number of CN220079396U, includes a shuttle bed and a shuttle frame. The shuttle bed and the shuttle frame are relatively rotatably arranged. A waist-shaped groove is provided on the inner bottom plate of the shuttle bed. One end of the waist-shaped groove is located outside the shuttle bed to form an air inlet, and the other end of the waist-shaped groove is located inside the shuttle bed to form an air guiding port facing the shuttle frame. A slope surface is provided on the end wall of the air guiding port. The included angle between the slope surface and the horizontal plane is a, and a is 40° to 50°. By providing a waist-shaped groove on the inner bottom plate of the shuttle bed, one end of the waist-shaped groove is located outside the shuttle bed, and a slope surface is provided at the other end of the waist-shaped groove, and the slope surface faces the outer bottom plate of the shuttle frame. Thus, when the shuttle bed rotates at a high speed relative to the shuttle frame, the air flow flows from the inner bottom plate of the shuttle bed to the direction of the shuttle frame through the thrust of the waist-shaped groove and the slope surface, so as to clean the fluff and garbage between the shuttle bed and the shuttle frame, improve the heat dissipation efficiency of the rotating shuttle. At the same time, the flowing air flow cools the rotating shuttle again, further enhancing the heat dissipation efficiency of the rotating shuttle. This technical solution adopts the method of providing a waist-shaped groove on the inner bottom plate of the shuttle bed. When the rotating shuttle rotates at a high speed, the air flow cools the rotating shuttle through the waist-shaped groove. In short, this technical solution uses the method of adding a flow channel to improve the air-cooling efficiency. However, this technical solution is still a passive air-cooling solution, which cannot actively control and reduce the temperature of the rotating shuttle. Secondly, providing a waist-shaped groove for air flow on the inner bottom plate of the shuttle bed has a high processing difficulty. A too large waist-shaped groove will affect the air flow velocity and generate vortices, resulting in uneven local temperature. Secondly, a too small waist-shaped groove may make it difficult to maintain the stable passage of the air flow. Therefore, this technical solution has a high processing difficulty and manufacturing cost and is not suitable for low-cost mass production. Secondly, the passive air-cooling heat dissipation method cannot actively regulate the temperature of the rotating shuttle, so the limitation is relatively high. Summary of the Utility Model

[0007] The utility model provides a heat conduction structure capable of keeping the rotating shuttle at a low temperature, which solves the problems in the prior art that the heat conduction structure of the rotating shuttle adopts a waist-shaped groove provided on the inner bottom plate of the shuttle bed for air flow to achieve the effect of passive air cooling, but this solution cannot solve the problems of high processing difficulty and high manufacturing cost. Secondly, it solves the problem of high limitation in use caused by the fact that the existing passive air-cooled rotating shuttle cannot actively regulate the temperature of the rotating shuttle.

[0018] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0019] The rotating shuttle of the structure of the present utility model solves the problem that the rotation on the current sewing machine causes the temperature of the rotating shuttle to rise too high after high-speed operation, resulting in thermal expansion and contraction of the rotating shuttle guide rail, leading to wear of the rotating shuttle guide rail and reducing the service life of the rotating shuttle.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0029] In a high-speed industrial sewing machine, the sewing needle generally reciprocates up and down at a speed of about 3,500 stitches per minute, while the bobbin case rotates at a high speed of about 7,000 revolutions per minute relative to the bobbin holder. With the continuous improvement of the sewing processing efficiency in the market, the required rotational speed of the rotating hook is getting faster and faster. Currently, during the high-speed production process of the sewing machine, the sewing needle reciprocates up and down at a high speed, and the rotating hook arranged below it, including components such as the bobbin case, bobbin holder, bobbin core, and bobbin shell, also rotates synchronously at a high speed correspondingly, so as to achieve high-precision and complex sewing operations. At present, the slide rails on the rotating hook are all made of metal or polymer materials. When the rotational speed of the rotating hook is too high, extremely high heat will be generated on the slide rails, resulting in thermal expansion and contraction, aggravating the wear of the slide rails, and reducing the service life of the rotating hook. The existing common solution is to spray lubricating oil to reduce the temperature rise of the slide rails, but spraying lubricating oil will cause pollution to the fabric. In addition, when using polymer materials to make the slide rails, although the polymer materials can delay and inhibit the temperature rise in a short time, under long-term and high-intensity work, the effect of delaying and inhibiting the temperature rise will gradually fail, and the problem of temperature rise still cannot be solved.

[0030] A rotating hook with excellent heat dissipation in the prior art includes a bobbin case and a bobbin holder. The bobbin case and the bobbin holder are relatively rotatably arranged. A waist-shaped groove is opened on the inner bottom plate of the bobbin case. One end of the waist-shaped groove is located outside the bobbin case to form an air inlet, and the other end of the waist-shaped groove is located inside the bobbin case to form an air guiding port facing the bobbin holder. A slope surface is provided on the end wall of the air guiding port, and the included angle between the slope surface and the horizontal plane is a, and a is 40° to 50°. By opening a waist-shaped groove on the inner bottom plate of the bobbin case, one end of the waist-shaped groove is located outside the bobbin case, and the other end of the waist-shaped groove is provided with a slope surface, and the slope surface faces the outer bottom plate of the bobbin holder. Thus, when the bobbin case rotates at a high speed relative to the bobbin holder, the air flow flows from the inner bottom plate of the bobbin case towards the direction of the bobbin holder through the thrust of the waist-shaped groove and the slope surface, so as to clean the fluff and garbage between the bobbin case and the bobbin holder, improve the heat dissipation efficiency of the rotating hook, and at the same time, the flowing air flow cools the rotating hook again, further enhancing the heat dissipation efficiency of the rotating hook. This technical solution adopts the method of opening a waist-shaped groove on the inner bottom plate of the bobbin case. When the rotating hook rotates at a high speed, the air flow cools the rotating hook through the waist-shaped groove. In short, this technical solution uses the method of adding a flow channel to improve the air-cooling efficiency. However, this technical solution is still a passive air-cooling solution and cannot actively control and reduce the temperature of the rotating hook. Secondly, opening a waist-shaped groove for air flow on the inner bottom plate of the bobbin case has a high processing difficulty. If the waist-shaped groove is too large, it will affect the air flow velocity and generate vortices, resulting in uneven local temperature. Secondly, if the waist-shaped groove is too small, it may be difficult to maintain the stable passage of the air flow. Therefore, this technical solution has a high processing difficulty and manufacturing cost and is not suitable for low-cost mass production. Secondly, the passive air-cooling heat dissipation method cannot actively regulate the temperature of the rotating hook, so the limitation is relatively high. To solve the above problems, this embodiment is provided.

[0031] Referring to Figures 1 to 6 This embodiment, Figure 1 is the front view schematic diagram of the overall structure of this embodiment, Figure 2This is an exploded schematic view of the overall structure of this embodiment. This embodiment is a heat-conducting structure that can keep the rotary shuttle at a low temperature. The main purpose of this structure is to maintain the stability of the rotary shuttle in a low-temperature environment. This structure consists of main parts such as a shuttle frame and a shuttle bed. Among them, the shuttle frame is the core component, which can rotate inside the shuttle bed. This design enables the rotary shuttle to operate flexibly in different directions. A plane is designed on the outer periphery of the bottom of the shuttle bed, and this plane is called the installation section plane. Its main function is to provide a stable installation platform for the heat-conducting structure. On this installation section plane, a specially designed heat-conducting structure is installed, which can effectively guide the heat flow and ensure the working performance of the rotary shuttle in a low-temperature environment. In addition, a lower shaft is fixed at the bottom of the shuttle bed, and this lower shaft is connected to the heat-conducting mechanism through a wireless charging mechanism. This design not only reduces complex wire connections but also improves the overall stability and reliability. Generally speaking, the design of this heat-conducting structure not only ensures the working performance of the rotary shuttle in a low-temperature environment but also improves the overall structural stability and reliability.

[0032] In addition to the above-mentioned shuttle frame and shuttle bed, the rotary shuttle of this embodiment also consists of a shuttle skin and a rotary shuttle plate. Both of these two parts present an arc-shaped sheet structure. This design is beneficial for better guiding the yarn during the textile process and improving the quality of the fabric. During the installation of the rotary shuttle, the shuttle skin is fixed to the outer surface of the shuttle frame through connection methods such as fasteners to ensure that the shuttle skin does not shift during high-speed operation. In this embodiment, since the shuttle skin is an arc-shaped sheet structure, one end of it is provided with a shuttle tip that is the same as that of the shuttle bed, and the arc-shaped tail of the shuttle skin helps to expand the thread loop guiding surface to guide the thread through the shuttle shell and tighten the bobbin thread. At the same time, the rotary shuttle plate is also tightly connected to the shuttle bed through a similar fixing method to ensure that the rotary shuttle can work stably during the textile process. The rotary shuttle plate is also an arc-shaped sheet structure, and one end of it is a tip, called a thread shedding hook, which is used to delay the time when the thread loop disengages from the shuttle bed.

[0033] Refer to Figure 4 This is the front view schematic diagram of the shuttle bed structure of this embodiment. The shuttle bed described in the figure is a mechanical structure, and its main components include a base and a receiving ring. The base is designed in a cylindrical shape, and this structure can provide stable support for the entire shuttle bed. On one side of the base, there is a receiving ring that is integrally fixed, and this ring-shaped structure helps the stable operation of the shuttle bed. On the other side of the base, it is the position for accommodating and fixing the end of the lower shaft. Such a design enables the shuttle bed to operate smoothly during operation.

[0034] The outer peripheral surface of the receiving ring is designed with an opening, which facilitates the entry and exit of the shuttle tip. The shuttle tip is an important part of the shuttle bed, and its presence enables the shuttle bed to complete the thread hooking operation during operation. In addition, a chute penetrating the inner peripheral surface is provided on the inner peripheral surface of the receiving ring. This design can make the shuttle bed run more smoothly during operation, reducing friction and wear.

[0035] A rectangular installation section is provided on the outer peripheral surface of the base, and the length of this section is between the radius and the diameter of the base. This design enables the base to be more stably installed on the shuttle bed and better withstand various forces during operation. On this installation section, a refrigeration module is fixedly attached. The function of this module is to maintain a stable temperature during the operation of the shuttle bed, thus ensuring the normal operation of the shuttle bed. Aluminum fins are fixed on the outer surface of the refrigeration module. This design can increase the heat dissipation area and improve the refrigeration effect.

[0036] Refer to Figure 3 For the front view schematic diagram of the shuttle frame structure of this embodiment, in the figure, the shuttle frame has a circular ring structure, and a strip-shaped plate is attached to one side of it, which is a strip-shaped board, and the strip-shaped board is integrally formed with the shuttle frame. The strip-shaped board is specially designed into a plate structure so that it can pass through the center of the shuttle frame and be fixed on the side of the shuttle frame. This design of the shuttle frame ensures that the strip-shaped board can be stably fixed in place.

[0037] On the other side surface of the strip-shaped board, that is, on the side far from the center of the shuttle frame, a shuttle shell fixing column is specially provided at the middle position. The main function of this shuttle shell fixing column is to fix the shuttle shell to ensure the stability and accuracy of the shuttle shell inside the shuttle frame.

[0038] On the other side of the shuttle frame, a curved surface protruding outward from the shuttle frame is designed at the edge part. This design not only increases the aesthetics of the shuttle frame, but also prevents the edge from being too sharp and cutting the wire, and at the same time provides more possibilities for its function. At the edge of this curved surface, a positioning groove is specially designed. The function of this groove is to provide an accurate positioning function during the use of the shuttle frame to ensure the precise positioning of the shuttle shell inside the shuttle frame.

[0039] A slide rail penetrating the entire outer peripheral surface of the shuttle frame is designed on the outer peripheral surface of the shuttle frame. This slide rail is designed to match the chute to achieve smooth sliding of the shuttle frame during operation and improve the operation efficiency of the shuttle frame. This design of the slide rail not only ensures the stability of the shuttle frame, but also improves the service life of the shuttle frame.

[0040] Refer to Figure 2 For the exploded schematic diagram of the overall structure of this embodiment, Figure 5 For the installation schematic diagram of the heat conduction structure of this embodiment, in Figure 2 and Figure 5The wireless charging mechanism is composed of a receiving coil and a wireless power transmission coil, wherein the receiving coil and the wireless power transmission coil are both mounted on the lower shaft, and a certain distance is maintained between them. The controller is connected to the receiving coil by an electrical connection so as to control and adjust the receiving coil. The lower shaft is also connected to the wireless power transmission coil by an electrical connection so as to transfer the energy received by the wireless power transmission coil to the lower shaft. The structure and position design of the receiving coil and the wireless power transmission coil enable them to efficiently transmit energy during the charging process, while ensuring the stability and reliability of wireless charging. In order to avoid the heating of the wireless charging mechanism due to wireless transmission and thus affect the temperature rise of the rotary shuttle, in this embodiment, the receiving coil and the wireless power transmission coil are both 5 to 10 cm away from the rotary shuttle, and the spacing between the receiving coil and the wireless power transmission coil is 2 to 5 cm. Too large a spacing affects the power transmission efficiency, and too small a spacing is not conducive to the heat dissipation of the wireless charging mechanism.

[0041] Reference Figure 6 This embodiment is a schematic diagram of the main view of the refrigeration module structure. The heat-conducting structure in the figure includes a refrigeration module and aluminum fins. The refrigeration module includes a refrigeration plate and a controller. The refrigeration plate is an arc-shaped block structure, and the controller is a rectangular block structure. The refrigeration plate and the controller are vertically fixed.

[0042] The role of aluminum fins is crucial. As a heat transmitter, the aluminum fins have a unique structural design that effectively increases the contact area with the air, thereby improving the heat dissipation efficiency. These aluminum fins are tightly and orderly arranged around the cooling fins, forming an efficient heat exchange system.

[0043] The surface of the aluminum fins has been specially treated to increase its corrosion resistance and thermal conductivity to the air. On the contact surface between the aluminum fins and the cooling fins, the designer uses precise welding technology to ensure that heat can be transferred from the cooling fins to the aluminum fins quickly and unimpeded.

[0044] In addition, this heat-conducting structure also has intelligent adjustment functions. The controller, as the "brain" of the entire system, is responsible for monitoring and adjusting the working status of the cooling plate. When the system detects that the temperature is too high, the controller will respond quickly and speed up the cooling speed by adjusting the current of the cooling plate. Conversely, when the temperature drops to the preset value, the controller will reduce the current and put the system into low-power mode to save energy.

[0045] Another highlight of this heat-conducting structure is its scalability. Due to the modular design, users can add or reduce the number of cooling modules and aluminum fins according to actual needs.

[0046] The beneficial effects of this embodiment are:

[0047] The structure of the rotating shuttle in this embodiment solves the problem of the rotation of the current sewing machine. After high-speed operation, the temperature rise of the rotating shuttle is too high, causing thermal expansion and contraction of the rotating shuttle, resulting in wear of the rotating shuttle guide rail, reducing the service life of the rotating shuttle, avoiding the use of lubricating oil and polluting the fabric. At the same time, the service life of the rotating shuttle is increased, and it has a broad market prospect.

[0048] The device structure of this embodiment is simple. By manufacturing a flat surface at the bottom of the shuttle bed to install the thermoelectric cooler, only a cutting plane needs to be made on the shuttle bed, with low technical content and low manufacturing cost. The wireless charging mechanism provides power for the thermoelectric cooler, and the thermoelectric cooler actively controls the temperature of the rotating shuttle. Secondly, the wireless charging mechanism is far away from the rotating shuttle, which can avoid the problem of the temperature rise of the rotating shuttle caused by the heat generated during the operation of the wireless charging mechanism. Moreover, both the wireless charging mechanism and the thermoelectric cooler are made of inexpensive materials, and have little impact on the overall cost of the device in this embodiment.

[0049] Except for the above embodiments, within the scope disclosed in the claims and the specification of the present invention, the technical features or technical data of the present invention can be reselected and combined to form new embodiments, which should also be regarded as specific embodiments of the present invention and within the protection scope of the present invention.
