Technical Field
[0001] The present invention relates to the technical field of muffler production, and particularly to an array composite muffler and its production line. Background Art
[0002] In order to maintain ventilation in the subway tunnel, a ventilator needs to be installed. Generally, the ventilator is large in size and generates a lot of noise during ventilation. Therefore, a muffler needs to be installed. Currently, the more commonly used one is the array muffler. The array muffler adopts columnar sound absorbers with an array distribution and consistent specifications inside. By flexibly adjusting the width and height directions, it can effectively improve the absorption of low-frequency and high-frequency noise, while reducing the system resistance loss, ventilating and reducing noise at the same time. A single muffler is a box structure surrounded by galvanized iron sheets or aluminum plates, and sound-absorbing cotton is filled inside.
[0003] In the prior art, when die-casting the end cover of the muffler, the demoulding speed is slow, and it is difficult to quickly push the product out of the mold and into the next process, resulting in a long mold opening and closing cycle, low equipment utilization rate, and affecting the overall production progress. Summary of the Invention

[0006] By adopting the above technical solutions, the second motor drives the threaded rod to rotate to drive the moving block to move, thereby driving the rotating rods to move. At this time, the top block slides upward, while ejecting the end cover, it drives the connecting piece to rotate on the base, so as to pour the formed end cover onto the conveyor belt and enter the next process, realizing the automatic ejection and transfer of the muffler components and improving the production efficiency.
[0007] Preferably, the clamping assembly includes a plurality of connecting rods, all of the plurality of connecting rods are fixedly connected to the ejecting block, a moving frame is fixedly connected between the tops of the plurality of connecting rods, a plurality of rotating rods are rotatably connected to the surface of the moving frame, and a plurality of moving plates are rotatably connected to the tops of the plurality of rotating rods.

[0015] Preferably, an array composite muffler includes a housing, a plurality of end caps are fixedly connected to the surface of the housing, an iron sheet is fixedly connected to the inner wall of the housing, and a plurality of sound-absorbing cotton are fixedly connected to the inner wall of the iron sheet.
[0016] Working principle: The user places the raw material on the top of the connecting member, starts the second motor to drive the threaded rod to rotate, makes the moving block move to the left, the moving block drives a plurality of rotating rods to move, pushes the ejecting block to slide downward inside the connecting member, the ejecting block drives the connecting rods and the moving frame to move downward, the moving frame drives a plurality of rotating rods to rotate, thereby driving the moving plates to slide on the third sliding rods, and the plurality of moving plates gradually approach and contact the raw material from different directions to clamp and fix the raw material; At this time, the first motor is started to drive the rotating member to rotate. The rotating member and the rotating disk have different rotation centers. When the rotating member rotates, the distance between the front end and the center of the rotating disk changes continuously. When the rotating member rotates clockwise to the left, the rotating disk rotates slowly. When the front end of the rotating member rotates to the right, the rotating disk rotates faster. When the rotating disk rotates, because the connection with the swing rod is not located at the center of the rotating disk, when the rotating member is on the left, the rotating disk rotates slowly and the connection between the rotating disk and the swing rod is far away from the rotation center of the swing rod, which makes the swing rod rotate slowly, thereby driving the moving member and the extrusion block to move downward slowly. The extrusion block extrude the raw material steadily at a lower speed to extrude the raw material into an end cover. As the rotating member continues to rotate, the rotating disk speed increases, and the swing rod drives the extrusion block to move upward quickly. After completing the extrusion action, the user starts the second motor again, and the second motor drives the threaded rod to rotate in the opposite direction, so that the moving block moves to the right, and the moving block drives multiple rotating rods to move, pushing the ejection block to slide upward inside the connecting piece, and the ejection block drives the connecting rod and the moving frame to move upward, and the moving frame drives multiple rotating rods to rotate, thereby driving the moving plate to slide outward on the third sliding rod, releasing the clamping of the end cover, and the ejection block continues to move upward and supports the connecting piece, and the connecting piece rotates around the hinge. When it rotates to a certain angle, it is blocked by the limit block, and the end cover falls onto the conveyor belt, and the conveyor belt transports the end cover to the next station.
[0017] The present invention provides an array composite muffler and its production line, which has the following beneficial effects: 1. In the present invention, the threaded rod is driven to rotate by the second motor, and the moving block is driven to move. At this time, the moving block drives the rotating rod to push against the ejection block to move, and when the moving block continues to move, it will drive the connecting piece to rotate, so as to eject the formed end cap and make it fall onto the conveyor belt on the right, thereby improving production efficiency and reducing the residence time of the end cap on the mold.
[0018] 2. In the present invention, the threaded rod is driven to rotate by the second motor. When the rotating rod pulls the ejection block to move downward, the connecting rod and the moving frame are pulled, thereby pulling the rotating rod to drive the moving plate to move, thereby fixing the unformed iron sheet in the center to prevent deviation during die casting, thereby avoiding end cover molding defects caused by the deviation of the iron sheet.
[0019] 3. In the present invention, the rotating member is driven to rotate by the first motor, thereby driving the rotating disk to rotate in the fixed disk. When the rotating disk rotates, the swing rod is moved to swing, thereby driving the movable member to move up and down. Since the connection between the rotating member, the rotating disk and the swing rod is not located at the center of the circle, the movable member drives the extrusion block to move downward at a slower speed and moves upward at a faster speed, thereby preventing the workpiece from being deformed, damaged or positioning deviation caused by excessive speed during stamping.

[0022] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the accompanying drawings of the specification. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.
[0023] Please refer to the attached Figure 1 - attached Figure 3The embodiment of the present invention provides an array composite silencer production line, including a connecting member 5, characterized in that a conveyor belt 12 is arranged on the outside of the connecting member 5, a plurality of hinges 14 are fixedly connected to the right side of the connecting member 5, a base 6 is fixedly connected between the plurality of hinges 14, a limiting block 25 is fixedly connected to the right side of the base 6, a connecting plate 7 is fixedly connected to the rear side of the base 6, a driving assembly is arranged on the front side of the connecting plate 7, a second motor 13 is fixedly connected to the left side of the base 6, a threaded rod 15 is fixedly arranged on the output end of the second motor 13, a moving block 16 is threadedly connected to the surface of the threaded rod 15, a plurality of rotating rods 17 are rotatably connected to the surface of the moving block 16, an ejection block 18 is rotatably connected between the plurality of rotating rods 17, the ejection block 18 is slidably connected to the connecting member 5, and a clamping assembly is arranged on the surface of the ejection block 18.
[0024] Specifically, after the end cover 2 is die-cast, the second motor 13 drives the threaded rod 15 to rotate. At this time, the moving block 16 moves to the right, driving the multiple rotating rods 17 to move, so that the ejection block 18 slides upward inside the connecting member 5, and the ejection block 18 ejects the formed end cover 2. When the moving block 16 continues to move, the ejection block 18 supports the connecting member 5, thereby supporting the connecting member 5 as a whole to rotate around the hinge 14. When the connecting member 5 rotates to a certain angle, it is blocked by the limit block 25 and cannot continue to rotate. At this time, the end cover 2 formed inside the connecting member 5 falls onto the conveyor belt 12, and the conveyor belt 12 transports the formed end cover 2 to the next station.
[0025] See attached Figure 3 and attached Figure 4 The clamping assembly includes a plurality of connecting rods 19, each of which is fixedly connected to the ejection block 18, a moving frame 20 is fixedly connected between the tops of the plurality of connecting rods 19, a plurality of rotating rods 22 are rotatably connected to the surface of the moving frame 20, and a moving plate 23 is rotatably connected to the tops of the plurality of rotating rods 22.
[0026] Specifically, when the ejector block 18 moves downward inside the connecting member 5, the connecting rod 19 and the moving frame 20 move downward accordingly. At this time, the moving frame 20 drives the multiple rotating rods 22 to rotate, thereby driving the moving plate 23 to slide on the third sliding rod 24. The multiple moving plates 23 gradually approach and contact the components from different directions. As the rotating rod 22 continues to rotate, the moving plate 23 clamps the raw material. At this time, the extrusion block 11 on the top moves downward to extrude the raw material into the end cover 2, ensuring that the muffler components will not fall off or shift during the production line circulation process. When the ejector block 18 moves upward and supports the connecting member 5 for rotation, it will also drive the moving frame 20 to move upward, thereby driving the moving plate 23 to move through the rotating rod 22. At this time, the multiple moving plates 23 move outward to facilitate the demolding of the formed end cover 2.
[0027] See attached Figure 1 and attached Figure 2, a fixing plate 8 is fixedly connected to the front side of the connecting plate 7. A plurality of first sliding rods 9 are slidably connected inside the fixing plate 8, and an extrusion block 11 is fixedly connected between the bottom ends of the plurality of first sliding rods 9.
[0028] Specifically, after fixing the raw material on the top of the connecting piece 5, the extrusion block 11 moves downward to extrude the raw material into the end cap 2.
[0029] Refer to the appendix Figure 5 and the appendix Figure 6 , a fixed disk 28 is fixedly connected to the front side of the connecting plate 7. A rotating disk 29 is rotatably connected inside the fixed disk 28. A swing rod 30 is rotatably connected to the front side of the connecting plate 7. The rotating disk 29 and the swing rod 30 are slidably connected, and a moving part 31 is slidably connected to the right side of the swing rod 30.
[0030] Specifically, after the user starts the first motor 10, the motor drives the rotating part 27 to start rotating. Since the rotation centers of the rotating part 27 and the rotating disk 29 are not concentric, during the rotation of the rotating part 27, the distance between the front end of the rotating part 27 and the center of the rotating disk 29 continuously changes. When the rotating part 27 rotates clockwise to the left, the front end is far from the center of the rotating disk 29, and at this time, the rotating speed of the rotating disk 29 is slower. When the front end of the rotating part 27 rotates to the right, it is closer to the center of the rotating disk 29, and the rotating speed of the rotating disk 29 becomes faster. When the rotating disk 29 rotates, since the connection part with the swing rod 30 is not located at the center of the rotating disk 29, when the rotating part 27 is on the left side, the rotating disk 29 rotates slowly and the connection part between the rotating disk 29 and the swing rod 30 is far from the rotation center of the swing rod 30, so that the rotating speed of the swing rod 30 is also slower, thereby driving the moving part 31 and the extrusion block 11 to move downward at a slower speed. As the rotating part 27 continues to rotate, the rotating speed of the rotating disk 29 becomes faster, and the swing rod 30 drives the extrusion block 11 to move upward quickly; the movement effect of the extrusion block 11 descending slowly and rising rapidly is realized. During the slow descent process, the end cap 2 can be smoothly extruded at a lower speed, preventing the end cap 2 from being deformed, damaged or displaced due to too fast speed, ensuring the processing accuracy and product quality. The rapid rising process shortens the idle stroke time, improves the working efficiency of the equipment, and improves the production capacity while ensuring the processing quality.
[0031] Refer to the appendix Figure 2 and the appendix Figure 6 , the driving assembly includes a first motor 10. The first motor 10 is fixedly connected to the connecting plate 7. A rotating part 27 is fixedly arranged at the output end of the first motor 10, and the front side of the rotating part 27 is slidably connected to the rotating disk 29.
[0032] Specifically, the first motor 10 drives the rotating part 27 to rotate. The slidable connection between the front side of the rotating part 27 and the rotating disk 29 enables the rotating part 27 to drive the rotating disk 29 to rotate synchronously during the rotation process. At the same time, the slidable connection between the rotating part 27 and the rotating disk 29 realizes the change of the rotating speed of the rotating disk 29 through a non-concentric transmission relationship.
[0033] Refer to the appendix Figure 3 , a plurality of second sliding rods 21 are fixedly connected to the inner wall of the connecting member 5, and the plurality of second sliding rods 21 are all slidably connected to the moving frame 20.
[0034] Specifically, the second sliding rod 21 provides a sliding track for the moving frame 20, so that the moving frame 20 can maintain a linear motion during the moving process, ensuring the accuracy and stability of the movement.
[0035] Refer to the appendix Figure 3 , a third sliding rod 24 is slidably connected inside each of the plurality of moving plates 23, and the plurality of third sliding rods 24 are all fixedly connected to the connecting member 5.
[0036] Specifically, when the moving frame 20 moves downward, it drives the rotating rod 22 to move, thereby driving the plurality of moving plates 23 to slide on the third sliding rod 24, so as to fix the unformed raw material.
[0037] Refer to the appendix Figure 1 and the appendix Figure 5 , the moving member 31 is slidably connected to the connecting plate 7, and the moving member 31 is fixedly connected to the extrusion block 11.
[0038] Specifically, the moving member 31 slides in the connecting plate 7 to prevent the moving member 31 from shifting during movement, ensuring that the moving member 31 always maintains a linear motion during movement, thereby driving the extrusion block 11 to move up and down to extrude the raw material.
[0039] Refer to the appendix Figure 3 , springs 26 are arranged on the surfaces of the plurality of second sliding rods 21, the tops of the plurality of springs 26 are fixedly connected to the moving frame 20, and the bottoms of the plurality of springs 26 are fixedly connected to the inner wall of the connecting member 5.
[0040] Specifically, during the process of the moving block 16 moving to the left, it drives the ejector block 18 to move. At this time, the moving frame 20 applies a pressure to the connecting member 5 through the spring 26, so that the lower surface of the connecting member 5 fits on the base 6, ensuring that the connecting member 5 will not rotate when the ejector block 18 initially slides inside the connecting member 5.
[0041] Refer to the appendix Figure 7 and the appendix Figure 8 , an array composite muffler, including a housing 1, a plurality of end caps 2 are fixedly connected to the surface of the housing 1, an iron sheet 3 is fixedly connected to the inner wall of the housing 1, and a plurality of sound-absorbing cotton 4 are fixedly connected to the inner wall of the iron sheet 3.
[0042] Specifically, the outer shell 1 of the muffler plays a role in protecting the internal structure and initially blocking the propagation of noise. Multiple end caps 2 are connected to the outer shell 1, ensuring the overall sealing of the muffler and assisting in controlling the direction of sound propagation. When noise enters the interior of the muffler, the sound-absorbing cotton 4 utilizes its porous structure to consume the sound energy, thereby effectively reducing the noise.
[0043] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
