Description

Technical Field

[0001] The present application relates to the field of knitting machinery, and in particular to a multi-directional heat dissipation needle selector body and a heat dissipation side plate thereof. Background Art

[0002] In the existing needle selector technology, there are some disadvantages of poor heat dissipation; therefore, when the needle selector works for a long time, the temperature inside the needle selector continues to rise due to the poor heat dissipation performance, which greatly reduces the service life of the coil or wire package installed inside the needle selector, or directly damages it due to high temperature; moreover, the existing needle selector basically adopts the following Fig.16 As shown in the figure, the closed side plate 32 covers and closes the internal space of the needle selector. The temperature rise generated when the needle selector is working can only be absorbed by the closed side plate 32 and then dissipated in a single radiation manner. The high temperature inside the needle selector cannot be dissipated by air convection, resulting in poor heat dissipation effect.

[0003] The following are common technical problems of needle selectors on the market: 1. Uneven heat dissipation: Some areas inside the needle selector will receive more heat accumulation, while other areas will not dissipate enough heat. This may cause the temperature in some areas to be too high, affecting the performance and life of the needle selector.

[0004] 2. Poor air circulation: The air circulation path inside the needle selector may be restricted, resulting in heat not being effectively transferred and dissipated. This may cause the temperature to rise, thereby reducing the working efficiency of the needle selector.

[0005] 3. Insufficient heat dissipation area: The heat dissipation surface area of ​​the needle selector may be limited and unable to effectively dissipate heat, which may cause the temperature of the needle selector to rise when running at high load, increasing the risk of failure and damage.

[0006] 4. Lack of heat dissipation material and structure optimization: The heat dissipation material and structure of the needle selector may not be fully optimized to provide the best heat dissipation performance. This may lead to inefficient heat transfer and insufficient convection and radiation heat dissipation.

[0007] These drawbacks may cause the needle selector to overheat when used for a long time or under high load, affecting its performance and reliability, and causing the internal coil and wire package to malfunction or be damaged. Therefore, when designing the needle selector, it is necessary to consider the heat dissipation effect and take corresponding measures to optimize the heat dissipation performance and improve the working stability and life of the needle selector.

The knife cavity 211 can effectively absorb and dissipate heat by designing a suitable structure and material, thereby improving the heat dissipation performance of the needle selector. The heat dissipation side plate 30 is located on the side of the needle selector body 20 and is closely connected thereto. The design of the heat dissipation side plate 30 takes into account the conduction and heat dissipation of heat, and has structures such as heat dissipation grooves and heat dissipation holes, which increases the surface area of ​​the heat dissipation side plate and promotes the heat dissipation, thereby improving the overall heat dissipation effect of the needle selector. A heat dissipation channel for air circulation inside and outside is formed between the needle selector body 20 and the heat dissipation side plate 30. Through structures such as heat dissipation grooves and heat dissipation holes, hot air flows inside the heat dissipation side plate and exchanges heat with the external air, thereby achieving effective heat dissipation and improving the heat dissipation effect.

In this way, the hot air inside can be replaced by more fresh outside air, forming a circulating heat dissipation channel to promote the conduction and dissipation of heat; Through the heat dissipation channel circulating inside and outside, heat can be more effectively transferred from the inside of the needle selector body 10 to the heat dissipation side plate 30, and finally dissipated to the external environment, which can improve the heat dissipation efficiency, reduce the operating temperature of the needle selector body 10, and maintain its normal operation and stability; Through the above design, the heat inside the needle selector body 10 can be effectively dissipated, and its operating temperature can be kept within a reasonable range, which will help to extend the service life of the needle selector body 10 and improve its performance and reliability.

[0061] Embodiment 4 Another structure of the heat dissipation side plate 30 is a heat dissipation flat side plate 31. The heat dissipation flat side plate 31 is provided with a plurality of second heat dissipation holes 310. The second heat dissipation holes 310 are through holes. The heat dissipation flat side plate is another variant of the heat dissipation side plate of the needle selector. It is provided with a plurality of second heat dissipation holes in the form of through holes. The through holes provide additional channels so that heat can be transferred and dissipated through the heat dissipation flat side plate, which provides more options for the thermal management of the needle selector and can be adapted and applied according to specific needs.

[0062] Embodiment 5 Reference Figure 4 , Figure 7 , Figure 9-10 As shown in, the semicircular grooves 205 arranged on both sides of the upper mounting table 2121 are staggered in lateral positions, and the central axis of the semicircular groove 205 on one side is located in the middle of the positions of two adjacent semicircular grooves 205 on the other side; the first semicircular groove 01 arranged on one side of the lower mounting table 2122 and the second semicircular groove 02 arranged on the other side are staggered in lateral positions, and the central axis of the first semicircular groove 01 is located in the middle of the positions of two adjacent second semicircular grooves 02 on the other side. Through the staggered arrangement of the semicircular grooves 205 of the upper mounting table 2121 and the first semicircular groove 01 and the second semicircular groove 02 of the lower mounting table 2122, the wire package 80 can be better limited during the installation process in the needle selector body 10, ensuring the stable installation and fixation of the wire package 80 and preventing it from loosening or falling off, thereby improving the reliability and performance of the needle selector body 10; The staggered arrangement of the semicircular groove 205 and the first semicircular groove 01 and the second semicircular groove 02 also increases the surface area of ​​the heat dissipation side plate 30. More surface area means a larger heat dissipation surface, which can provide more heat dissipation channels, and help to effectively dissipate the heat generated inside the needle selector body 10 to the surrounding environment, thereby reducing the operating temperature of the needle selector body 10 and maintaining its normal operation and stability. Through the above-mentioned layout and staggered design, the wire package limiting effect and heat dissipation capacity of the needle selector body 10 can be improved, thereby enhancing its overall performance and reliability.

[0063] Embodiment 6 Reference Figure 4 As shown in , after the needle selector body 20, the heat dissipation side plate 30, and the pressure plate 40 are assembled and several wire packages 80 are installed in the needle selector body 10, the distance between the inner side surface of the heat dissipation side plate 30 and the wire package 80 is not less than 3 mm, and the distance between the upper side surface of the pressure plate 40 and the inner side surface of the heat dissipation side plate 30 is not less than 5 mm. A certain distance of at least 3 mm is reserved between the inner side of the heat dissipation side plate 30 and the wire package 80. Ensure that there is enough space around the wire package 80 for heat dissipation to avoid too close contact that causes the heat to not be effectively dissipated. Reserving heat dissipation space can improve the heat dissipation efficiency of the needle selector body 10, reduce its operating temperature, and thus improve its stability and life; Maintaining a distance of at least 5 mm between the upper side surface of the pressure plate 40 and the inner side surface of the heat dissipation side plate 30 can effectively reduce the conduction of heat between the pressure plate 40 and the heat dissipation side plate 30. By maintaining a certain gap and reducing the heat conduction path, excessive heat transfer to the pressure plate 40 can be avoided, keeping its relatively low temperature, preventing heat from affecting other parts of the needle selector body 10, ensuring its normal operation and reliability, achieving good heat dissipation effects, and effectively improving the thermal management capabilities of the needle selector body 10, ensuring its normal operation and extending its service life.

[0064] The implementation principle of a multi-directional heat dissipation needle selector body and its heat dissipation side plate in the embodiment of the present application is: 1. Needle selector main body structure: The needle selector main body includes a needle selector body, a heat dissipation side plate and a pressure plate. The needle selector body has a heat dissipation side plate mounting platform for mounting the heat dissipation side plate and the wire package.

[0065] 2. Heat dissipation side panel mounting platform and wire package installation: The upper end of the heat dissipation side panel mounting platform of the needle selector body is provided with a knife accommodating cavity. The heat dissipation side panel mounting platform is also provided with a concave wire package mounting platform, which is divided into an upper mounting platform and a lower mounting platform by a through groove. The wire package is installed between the upper mounting platform and the lower mounting platform.

[0066] 3. Semicircular grooves and heat conducting rod position limiting: Several semicircular grooves are set on both sides of the upper mounting platform for limiting the position of the wire package. Several first semicircular grooves are set on one side of the lower mounting platform for limiting the position of the heat conducting rod. Several second semicircular grooves are set on the other side for limiting the position of the heat conducting rod. The positions of the semicircular grooves are aligned to ensure the stable position limiting of the wire package and the heat conducting rod.

[0067] 4. Heat dissipation slot 1 and heat dissipation holes: The knife chamber is provided with a heat dissipation slot 1, and a plurality of penetrating second heat dissipation holes are provided on the two side walls of the heat dissipation slot 1. A plurality of penetrating first heat dissipation holes are provided at the bottom of the heat dissipation slot 1, one end of which is connected to the semicircular slot.

[0068] 5. Pressing plate and fixing: The second screw holes are arranged on the two sides of the lower mounting platform, and the pressing plate is fixed to the lower mounting platform by screws. A number of third semicircular grooves are arranged on the connecting surface of the pressing plate, corresponding to the first semicircular groove and the second semicircular groove, to form the wire package installation hole.

[0069] Installation of the heat dissipation side panel: The heat dissipation side panel is screwed to the first screw hole of the heat dissipation side panel mounting platform through screws to fix the heat dissipation side panel to the end surface of the heat dissipation side panel mounting platform.

[0070] 6. Through the above structure and principle, the multi-directional heat dissipation needle selector realizes the heat dissipation function. The heat is transferred from the wire package to the heat-conducting rod, and heat is exchanged with the external environment through the heat dissipation holes and heat dissipation slots. At the same time, through the design of the limit device and the installation hole, the stable installation and position alignment of each component are ensured, so that the heat dissipation effect is better. 7. Heat dissipation refers to the process of transferring heat from an object to the surrounding environment to reduce the temperature of the object. In the multi-directional heat dissipation needle selector body and its heat dissipation side plate, the heat dissipation principle mainly involves the following aspects: 8. Heat conduction: Heat is transferred from the wire package to the heat-conducting rod, and the heat is transferred along the path of the heat-conducting rod through the heat conduction properties of the heat-conducting rod.

[0071] 9. Heat dissipation holes: The knife cavity of the needle selector body is provided with a heat dissipation slot 1 and a through heat dissipation hole. The function of the heat dissipation hole is to transfer the heat from the heat dissipation slot 1 to the external environment. Through heat conduction and convection, the heat dissipation hole causes the heat to be dispersed from the knife cavity.

[0072] 10. Air circulation: The design of the heat dissipation side plate allows air to circulate inside and outside the needle selector body. Heat is transferred to the inside of the heat dissipation side plate through the heat dissipation holes of the knife chamber, and then heat is exchanged with the outside air through the heat dissipation slots and heat dissipation holes on the heat dissipation side plate. Such air circulation helps to speed up the heat dissipation and improve the heat dissipation efficiency.

[0073] 11. Heat dissipation side panel structure: The heat dissipation side panel adopts a special structural design, such as heat dissipation grooves, heat dissipation holes, etc. These structures increase the surface area of ​​the heat dissipation side panel, provide more heat dissipation surface, and enhance the ability to dissipate heat.

[0074] Through the combined effect of the above heat dissipation principles, the multi-directional heat dissipation needle selector body and its heat dissipation side plates can effectively dissipate heat from the wire package and the heat conducting rod, reduce their temperature, and ensure the normal operation and stability of the needle selector.

[0075] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
