Description

Technical Field

[0001] This utility model relates to the field of textile machinery technology, specifically a high heat dissipation type needle selector coil mounting base. Background Technology

[0002] The needle selector is a core component in textile machinery, and its coil generates a lot of heat during long-term operation. Traditional mounting bases mostly adopt a closed mechanism with poor heat dissipation performance, resulting in excessive coil temperature rise, affecting equipment life and even causing malfunctions. Although there are heat dissipation holes in existing technologies, the heat dissipation efficiency is low and it is difficult to meet the needs of high-speed textile machinery. Therefore, a high heat dissipation needle selector coil mounting base is proposed. Utility Model Content

[0003] The main purpose of this utility model is to provide a solution that can effectively address the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a high heat dissipation type needle selector coil mounting base, comprising a mounting base body, a plurality of mounting slots disposed on the mounting base body, a mounting cavity disposed in the mounting slots for mounting the coil, and a fixing plate detachably connected to the mounting base body for pressing the coil, characterized in that: it further comprises a plurality of heat dissipation fins disposed around the mounting base body and a plurality of heat dissipation holes disposed in an array at the bottom of the mounting base body; the inner wall of the mounting cavity is coated with a thermally conductive layer, and the outer surface of the mounting base body is coated with a heat insulation layer, and the heat insulation layer covers all the heat dissipation fins.

[0005] Preferably, the mounting base body has a hollow cuboid structure.

[0006] Preferably, the top of the mounting base body is provided with a limiting hole and a threaded hole for cooperating with the fixing plate.

[0007] Preferably, the fixing plate is provided with a through hole for fixing the coil, a limiting block that matches the limiting hole on the mounting base body, and a mounting hole connected by a screw and a threaded hole.

[0008] Preferably, the heat sink is a finned structure with spaced fins.

[0009] Preferably, the thermally conductive layer is a thermally conductive silicone or graphene thermally conductive film.

[0010] This invention offers the following advantages: A three-dimensional heat dissipation channel is constructed through the combined design of a heat sink and heat dissipation holes. The heat sink significantly increases the contact area with air, thereby accelerating the convective heat transfer process on the surface. The heat dissipation holes promote airflow within the mounting base, jointly achieving rapid heat dissipation. Compared to traditional mounting bases without heat dissipation structures, this significantly improves heat dissipation efficiency, effectively preventing performance degradation of the coil due to high-temperature aging, and thus extending the coil's service life. The heat-conducting layer on the inner wall of the mounting cavity can quickly conduct the heat generated when the coil is working to the mounting body, reducing the accumulation of heat in the local area of ​​the mounting cavity; at the same time, the heat insulation layer on the outer surface forms an effective thermal barrier, preventing heat from spreading to the mechanical connection area between the mounting base and other parts of the equipment, thereby avoiding precision drift or functional failure of the surrounding precision parts due to heat, and ensuring that the entire needle selector system can operate stably for a long time. The fixing plate not only enables rapid positioning and reliable clamping of the coil, effectively preventing coil displacement or loosening due to vibration during operation, but also ensures installation accuracy and improves the stability of the overall structure through the cooperation of the limiting block and limiting hole. At the same time, the tight fit between the fixing plate and the mounting base further enhances the continuity of the heat dissipation path, which is conducive to the heat generated by the coil being conducted to the mounting base through the fixing plate, thereby improving the overall heat dissipation effect.

[0013] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0014] See appendix Figure 1-5As shown, a high-heat-dissipation needle selector coil mounting base includes a mounting base body 1, several mounting slots 2 disposed on the mounting base body 1, a mounting cavity 3 disposed in the mounting slots 2 for mounting the coil, and a fixing plate 4 detachably connected to the mounting base body 1 for pressing the coil. The base is characterized by further including several heat sinks 5 disposed around the mounting base body 1 and several heat dissipation holes 6 arranged in an array at the bottom of the mounting base body 1; the inner wall of the mounting cavity 3 is coated with a thermally conductive layer 7, and the outer surface of the mounting base body 1 is coated with a heat insulation layer, which covers all the heat sinks 5; the mounting base body 1 is made of aluminum alloy or copper alloy, reducing the overall weight while ensuring strength.

[0015] A three-dimensional heat dissipation channel is constructed through the combined design of "heat sink 5 + heat dissipation holes 6". Among them, heat sink 5 significantly increases the contact area with air, thereby accelerating the convective heat transfer process on the surface; heat dissipation holes 6 promote air circulation inside the mounting body 1, and together they achieve rapid heat dissipation. Compared with traditional mounting bodies without heat dissipation structure, this design can significantly improve heat dissipation efficiency, effectively avoid the performance degradation of the coil due to high temperature aging, and thus extend the service life of the coil. The heat-conducting layer 7 on the inner wall of the mounting cavity 3 can quickly conduct the heat generated when the coil is working to the mounting body 1, reducing the accumulation of heat in the mounting cavity 3. At the same time, the heat insulation layer on the outer surface forms an effective thermal barrier, preventing heat from spreading to the mechanical connection area between the mounting base and other components of the equipment, thereby avoiding precision drift or functional failure of the surrounding precision components due to heat, and ensuring that the entire needle selector system can operate stably for a long time.

[0016] See appendix Figure 1-2 As shown, the mounting base body 1 has a hollow cuboid structure; the top of the mounting base body 1 is provided with a limiting hole 11 and a threaded hole 12 for cooperating with the fixing plate 4; the fixing plate 4 is provided with a through hole 41 for fixing the coil, a limiting block 42 that matches the limiting hole 11 on the mounting base body 1, and a mounting hole 43 that is connected to the threaded hole 12 by a screw.

[0017] During installation, first place the coil into the mounting cavity 3 until it reaches the bottom, with the coil cable positioned within the arc-shaped groove of the mounting cavity 3. Then, install the mounting cavity 3 into the mounting groove 2 of the mounting base body 1. Next, press the fixing plate 4 onto the mounting base body 1, allowing the coil core to pass through the through hole 41, thereby securely confining the coil within the mounting cavity 3. At this point, the limiting block 42 on the fixing plate 4 engages with the limiting hole 11 on the mounting base body 1 for precise positioning. Finally, use a screw to pass through the mounting hole 43 and connect it to the threaded hole 12 on the mounting base body 1 to complete the fastening installation of the fixing plate 4.

[0018] By setting the fixing plate 4, not only can the coil be quickly positioned and reliably clamped, effectively preventing the coil from shifting or loosening due to vibration during operation, but the cooperation between the limiting block 42 and the limiting hole 11 also ensures the installation accuracy and improves the stability of the overall structure. At the same time, the close cooperation between the fixing plate 4 and the mounting body 1 further enhances the continuity of the heat dissipation path, which is conducive to the heat generated by the coil being conducted to the mounting body 1 through the fixing plate 4, thereby improving the overall heat dissipation effect.

[0019] See appendix Figure 1-2 As shown, the heat sink 5 is a finned structure with spaced fins, which increases the ventilation area and improves heat dissipation.

[0020] See appendix Figure 1 As shown, the thermally conductive layer 7 is a thermally conductive silicone or graphene thermally conductive film.

[0021] When using this utility model, first install the needle selector coil in the mounting cavity 3 until it reaches the bottom, with the coil cable in the arc-shaped groove of the mounting cavity 3. Then, install the mounting cavity 3 into the mounting groove 2 of the mounting base body 1. Place the fixing plate 4 on the mounting base body 1, so that the coil core passes through the through hole 41 on the fixing plate 4. The limiting block 42 is inserted into the limiting hole 11 of the mounting base body 1 and connected to the threaded hole 12 on the mounting base body 1 by screws passing through the mounting hole 43 on the fixing plate 4.

[0022] During the operation of the needle selector, the heat generated by the coil is transferred to the interior of the mounting body 1 through the heat-conducting layer 7, and then dissipated into the air through the heat dissipation holes 6 and the heat sink 5. At the same time, the heat insulation layer reduces the transfer of heat to non-heat dissipation areas and improves heat dissipation efficiency.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
