Description

Technical Field

[0001] This utility model relates to the field of speaker mesh hot pressing technology, specifically to a speaker mesh hot pressing production equipment. Background Technology

[0002] As a commonly used modern sound-generating component, speakers often require a mesh fabric to be installed on the surface of the sound-generating structure during the production process to prevent dust from the external environment from entering the interior of the sound-generating structure. First, hot melt adhesive is applied to the outer surface of the sound-generating structure, and then the mesh fabric is moved to the top of the sound-generating structure. Then, an external speaker mesh fabric hot pressing production equipment is used to hot press and fix the hot melt adhesive and the mesh fabric, thus completing the fixing of the speaker mesh fabric. However, existing speaker mesh fabric hot pressing production equipment lacks load-bearing space adjustment components. During the use of the speaker mesh fabric hot pressing production equipment, it is impossible to adjust the load-bearing space height of the speaker according to the usage needs, thus affecting the applicability of the speaker mesh fabric hot pressing production equipment.

[0003] Compared to existing speaker mesh hot pressing production equipment, this utility model adds a load-bearing space adjustment component. Before using the speaker mesh hot pressing production equipment, the height of the speaker load-bearing space can be adjusted according to the usage needs. Then, during the subsequent use of the hot pressing structure, the height of the speaker load-bearing space can be adjusted, making it suitable for the hot pressing of mesh for most speakers.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6This utility model provides a technical solution: including springs 3 and lifting plates 5. The lifting plates 5 are installed at the tail ends of four sets of springs 3. The springs 3 are installed on the top of the fixed plate 1, and have a high stiffness coefficient, providing support to the top of the lifting plates 5. Simultaneously, when the connecting buckle 4 is released, it drives the lifting plates 5 to move upwards. The lifting plates 5 are installed at the tail ends of the four sets of springs 3, providing a fixing point for the connecting shells 6 that are installed through the top of them. Eight sets of connecting shells 6 are installed through the top of the lifting plates 5, providing a fixing point for the motor 8 installed on the top of it, and also providing a fixing point for the extension rods 7 that are fitted inside. The extension rods 7 are fitted inside the connecting shells 6, and the extension rods 7 are fitted inside the connecting shells 6 and connected to the second threaded rod 9. When the second threaded rod 9 rotates, the extension rods 7 move along the belt of the second threaded rod 9. The second threaded rod 9 moves up and down, thereby driving the heating plate 13 indirectly connected to its tail end to move up and down. The top of the connecting shell 6 is equipped with a motor 8, and the output end of the motor 8 extends to the inside of the connecting shell 6. When electrical energy is transmitted to the inside of the motor 8 through the control panel 17, the motor 8 transmits the rotational power to the inside of the second threaded rod 9 through electromagnetic effect. The output end of the motor 8 is equipped with the second threaded rod 9, and the second threaded rod 9 meshes with the extension rod 7. The second threaded rod 9 rotates under the drive of the motor 8, transmitting the rotational power to the inside of the extension rod 7, driving the extension rod 7 to move up and down. Two sets of limiting rods 10 are installed on the inside of the connecting shell 6, and the limiting rods 10 are fitted and connected to the extension rod 7. The limiting rods 10 are installed inside the connecting shell 6 and fitted with the extension rod 7 to prevent the extension rod 7 from rotating with the second threaded rod 9.A heating plate 13 is installed at the bottom of the fixing buckle 11. When the extension rod 7 extends or retracts, the heating plate 13 moves up and down, contacting the mesh fabric and speaker. Simultaneously, it conducts heat from the heating element 14 to the interior of the mesh fabric, thus completing the heat pressing of the mesh fabric and speaker. The inner wall of the heating plate 13 is equipped with heating elements 14. When electrical energy is supplied to the interior of the heating elements 14 via the temperature control switch 15, the resistance wire inside the heating elements 14 continuously transfers heat to the interior of the heating plate 13 through the electrothermal effect. A temperature control switch 15 is installed on the top of the device. When electrical energy is supplied to the temperature control switch 15 via the power connector 16, the temperature control switch 15 supplies electrical energy to the heating element 14. At the same time, it detects the temperature inside the heating plate 13. When the heat inside the heating plate 13 is too high, the resistance value inside the temperature control switch 15 increases, cutting off the electrical energy conducted to the heating element 14. The power connector 16 is embedded in the top of the heating plate 13 and is located on one side of the temperature control switch 15. Before using the device, connect the power cable to the control panel 17 to the power supply. The power connector 16 is connected to the temperature control switch 15. A control panel 17 is mounted on the front of the fixing plate 1 via a connecting plate. The control panel 17 is connected to an external power supply and to the power connector 16 via an external power supply cable. When the mesh fabric needs to be hot-pressed, the control panel 17 can be pressed by external force to control the electromagnetic relay inside the control panel 17 through the capacitor screen, and power is supplied to the power connector 16 and the motor 8 respectively. Several through holes 18 are provided through the top of the fixing plate 1. Located inside the four sets of springs 3, the connecting hole 18 extends to the top of the fixing plate 1. When the speaker moves to the top of the fixing plate 1, it provides a space for the speaker's power cord to exit. Four sets of support rods 19 are installed at the bottom of the fixing plate 1, providing fixing points for the flange 20 installed at its bottom. The flange 20 is installed at the bottom of the support rods 19. Before using the device, insert the external bolts into the flange 20 and then into the external fixing plane to complete the overall fixing of the hot-pressing equipment.

[0026] Working principle: First, insert the external bolts into the flange 20 and the external fixing plane to fix the entire hot pressing equipment. Connect the power cable connected to the control panel 17 to the power connector 16. Then, move the speaker to be hot-pressed to the top of the fixing plate 1 and guide the power cable connected to the speaker through the connecting hole 18 to the outside of the fixing plate 1. Then, press the control panel 17 with external force to control the electromagnetic relay inside the control panel 17 through the capacitor screen, and transmit electrical energy to the power connector 16 and the motor 8 respectively. The power connector 16 transmits electrical energy to the temperature control switch 15, and the temperature control switch 15 transmits electrical energy to the motor 8. Inside the heat pipe 14, the resistance wire inside the electric heating pipe 14 continuously transfers heat to the interior of the heating plate 13 through the electrothermal effect. The electric motor 8 transfers rotational power to the interior of the second threaded rod 9 through the electromagnetic effect. The second threaded rod 9 rotates under the drive of the electric motor 8, transferring rotational power to the interior of the extension rod 7, causing the extension rod 7 to move up and down. The extension rod 7 moves up and down along the second threaded rod 9 under the drive of the second threaded rod 9, thereby causing the heating plate 13 indirectly connected to its tail end to move up and down. When the heating plate 13 moves up and down and comes into contact with the mesh and the speaker, it transfers the heat from the electric heating pipe 14 to the interior of the mesh, thereby completing the heat pressing of the mesh and the speaker.

[0027] Please see Figure 1 and Figure 5 This utility model provides a technical solution: it includes a fixed plate 1 and a first threaded rod 2. Four sets of first threaded rods 2 are installed on the top of the fixed plate 1. The first threaded rods 2 are installed on the top of the fixed plate 1 and provide connection points for the connecting buckles 4 threadedly connected to the top of the fixed plate 1. Four sets of springs 3 are installed on the top of the fixed plate 1, and the springs 3 are located on the outside of the first threaded rods 2. The springs 3 are installed on the top of the fixed plate 1 and have a high stiffness coefficient, which provides support for the top of the hanging plate 5. At the same time, when the connecting buckles 4 are loosened, they drive the hanging plate 5 to move upward. The outer surface of the first threaded rod 2 is threadedly connected to the connecting buckles 4. When it is necessary to adjust the height of the speaker's carrying space, the four sets of connecting buckles 4 can be rotated simultaneously by external force, which drives the connecting buckles 4 to move up and down along the first threaded rods 2, thereby generating pressure on the hanging plate 5, and thus adjusting the position of the hanging plate 5 and the height of the speaker's carrying space.

[0028] Please see Figure 1 , Figure 2 and Figure 4This utility model provides a technical solution: including an extension rod 7 and a fixing buckle 11. The tail end of the extension rod 7 is fitted with the fixing buckle 11, and the fixing buckle 11 is fitted with the tail end of the extension rod 7. At the same time, it provides a fixing point for the threaded bolts 12 that penetrate into it. The outer surface of the fixing buckle 11 is threaded with four sets of threaded bolts 12, and the threaded bolts 12 are connected to the extension rod 7. The threaded bolts 12 are inserted into the interior of the fixing buckle 11 and the extension rod 7. When it is necessary to replace the heating plate 13, it can be disassembled by rotating the threaded bolts 12, thereby facilitating the replacement of the hot-pressed structure.
