[0002] Currently, all consumer electronics products with acoustic functions typically use precision-woven acoustic mesh and waterproof, breathable membranes at the sound outlet to protect the speakers and microphones. This material effectively prevents external contaminants such as dust, metallic particles, water, oil, and cosmetics.
[0003] A search revealed a fabric trimming device disclosed in Chinese Patent Publication No. CN213804543U, comprising: a workbench; a movable pressure plate disposed above the workbench; and a cutting assembly disposed on the workbench. The cutting assembly includes a surrounding plate and a cutting tool. The surrounding plate forms a placement space with a first contour shape, and the cutting tool is disposed within the placement space with its blade facing upwards, and the cutting tool forms a second contour shape. The first contour shape is the edge contour shape of the fabric to be trimmed, and the second contour shape is the pre-set trimming shape of the fabric. The pressure plate is configured to cover the cutting assembly, so that the cutting tool's blade can cut the fabric to be trimmed under the applied force of the pressure plate. This fabric trimming device has the advantages of simple structure, convenient use, improved efficiency, and easy promotion and application.
[0004] While the above solutions have the advantages of simple structure, convenient use, and improved efficiency, the aforementioned patents are difficult to adapt to different cutting scenarios. In actual use, the required size of different mesh fabrics varies, and the existing patents have strong limitations, which are not conducive to the cutting operation of mesh fabric width. Therefore, we provide a hot melt edge-sealing device for acoustic mesh fabric to solve the above problems. Utility Model Content

[0022] This utility model embodiment provides a hot melt edge-sealing device for acoustic mesh fabric.
[0023] Please see Figure 1 The device includes a support body 1 and a hot cutting mechanism 10. A guide roller 18 is rotatably connected to the inner wall of the support body 1. The purpose of setting the guide roller 18 is to allow the acoustic mesh fabric to pass through two guide rollers 18 during the conveying process, which is beneficial for cutting off the width of the acoustic mesh fabric on both sides. A display controller 19 is fixedly connected to one side of the support body 1. The purpose of setting the display controller 19 is to effectively control the electrical components in this application. The control method is electrical connection. The display controller 19 is existing technology, so this application will not describe the display controller 19 in detail.
[0024] Please see Figure 2 The inner wall of the support body 1 is slidably connected to the central control slide plate 2. The support body 1 can apply a control effect to the central control slide plate 2 to ensure that the central control slide plate 2 can only move horizontally within the support body 1. The top of the central control slide plate 2 is fixedly connected to the threaded slider 15. The central control slide plate 2 and the threaded slider 15 are in a direct connection state, and the two maintain a linkage effect.
[0025] Please see Figure 1 , Figure 2 and Figure 3 The inner wall of the threaded slider 15 is threadedly connected to the outer circumferential surface of the one-way lead screw 16. The cooperation between the threaded slider 15 and the one-way lead screw 16 allows the one-way lead screw 16 to rotate effectively when the threaded slider 15 is restricted, thus driving the threaded slider 15 to translate. One end of the one-way lead screw 16 is fixedly connected to the output shaft of the DC motor 17. The DC motor 17 is fixedly connected to one side of the bracket body 1. The purpose of setting the DC motor 17 is to provide sufficient power support for the rotation of the one-way lead screw 16. The DC motor 17 is existing publicly available technology, and this application will not elaborate further on the DC motor 17.
[0026] Please see Figure 3 The center control slide plate 2 has a slidable cam 4 connected in the inclined groove 3. The purpose of setting the center control slide plate 2 is to effectively control the relative movement of the two cams 4 through the symmetrical distribution of the two inclined grooves 3. The purpose of setting the cams 4 is to effectively reduce the frictional resistance between the components.
[0027] Please see Figure 2 and Figure 4 The force-bearing cam 4 is rotatably connected to the top of the control slider 5. The control slider 5 can apply a control effect to the force-bearing cam 4, ensuring that the force-bearing cam 4 can rotate in place. The inner wall of the control slider 5 is slidably connected to the outer circumferential surface of the guide rod 6. The guide rod 6 is fixedly connected to the inner wall of the bracket body 1. There are two guide rods 6 in total. The purpose of setting the guide rods 6 is to effectively apply a control effect to the control slider 5, thereby ensuring that the control slider 5 slides smoothly.
[0028] Please see Figure 4The bottom of the control slider 5 is fixedly connected to a U-shaped bracket 7, and a protective shell 11 is fixedly connected to one side of the U-shaped bracket 7. The protective shell 11 can effectively protect its internal components and apply a control effect to the one-way worm gear 12, ensuring that the one-way worm gear 12 can rotate in place. The one-way worm gear 12 is rotatably connected to the inner wall of the protective shell 11. The thread on the outer circumferential surface of the one-way worm gear 12 meshes with the teeth on the outer circumferential surface of the planar worm wheel 14. The tight fit between the one-way worm gear 12 and the planar worm wheel 14 can effectively realize the force transmission effect and has a self-locking effect, ensuring the stability of subsequent component movement.
[0029] Please see Figure 4 The planar worm gear 14 is fixedly connected to the outer circumference of the linkage shaft 8. The planar worm gear 14 and the linkage shaft 8 are in a direct connection state, and the two maintain the linkage effect. One end of the one-way worm gear 12 is fixedly connected to an external turntable 13. The outer circumference of the external turntable 13 is provided with anti-slip texture. The inner wall of the U-shaped bracket 7 is rotatably connected to the linkage shaft 8. The U-shaped bracket 7 can apply a control effect to the linkage shaft 8 to ensure that the linkage shaft 8 rotates in place.
[0030] Please see Figure 4 A crank support plate 9 is fixedly connected to the outer circumference of the linkage central shaft 8. A hot cutting mechanism 10 is fixedly connected to one end of the crank support plate 9. The linkage central shaft 8, the crank support plate 9 and the hot cutting mechanism 10 maintain a linkage effect. The hot cutting mechanism 10 is mainly used to melt the mesh fabric to achieve the purpose of cutting off the waste edge. The hot cutting mechanism 10 first uses a transformer to convert the 220V voltage to 6V, then connects to the display controller 19, and then connects to the resistance wire. Through the design of the temperature control system of the display controller 19, the effect of precise temperature control can be achieved, so that the waste edge can be burned off in time without accidentally injuring the operator.
[0031] Working Principle: In use, the acoustic mesh fabric is passed through two guide rollers 18. Then, the external turntable 13 is manually rotated, which drives the planar worm gear 14 to rotate via the one-way worm 12. This causes the crank support plate 9 to rotate around the linkage central shaft 8, changing the position of the heat-cutting mechanism 10 connected to the crank support plate 9. This brings the heat-cutting mechanism 10 into contact with the acoustic mesh fabric. The control display controller 19 then activates the heat-cutting mechanism 10, causing it to heat up. The acoustic mesh fabric then moves under the action of the external traction device, allowing the heat-cutting mechanism 10 to cut the width of the acoustic mesh fabric on both sides. When the width of the acoustic mesh fabric changes, only... The DC motor 17 is started by the display controller 19, which drives the one-way lead screw 16 to rotate. At this time, the central control slide plate 2, which is connected to the threaded slider 15, is restricted by the bracket body 1. Therefore, the one-way lead screw 16 can drive the central control slide plate 2 to translate through the threaded slider 15. At this time, the control slider 5, which is connected to the force cam 4, is controlled by the guide rod 6. Therefore, the central control slide plate 2 can drive the linkage central shaft 8 to translate through the force cam 4. Through the design of the same components, the two control sliders 5 can move relative to each other, thereby changing the distance between the two hot cutting mechanisms 10, so that the hot cutting mechanism 10 can be adapted to different cutting scenarios.
