Technical Field
[0001] This utility model relates to the field of raw material mixing technology, specifically to a mixing device for producing sound-absorbing panels. Background Technology
[0002] Raw material mixing refers to the process of combining different types or forms of raw materials together to achieve a uniform and homogeneous effect. This process is widely used in various industries, such as food processing, chemicals, pharmaceuticals, and building materials.
[0003] According to a public disclosure (Publication No.: CN217248524U), a mixing device for producing sound-absorbing panels includes a mixing tank. A partition is fixedly connected to the lower inner wall of the mixing tank. Mounting plates are fixedly connected to both sides of the mixing tank. A cylinder is bolted to the top of the mounting plates. A connector is fixedly connected to the output end of the cylinder, and a top cover is fixedly connected to the other end of the connector. A pretreatment tank is fixedly connected to the upper inner wall of the mixing tank. This mixing device for producing sound-absorbing panels uses three pretreatment tanks within the mixing tank to separately mix granular cotton, perlite, and waste paper. A first motor and a water supply pipe allow for individual mixing and water injection of the corresponding raw materials. A discharge pipe transports various raw materials to the mixing zone, and a second motor mixes and stirs the various raw materials. This mixing device for producing sound-absorbing panels has a reasonable structure, and its integrated design effectively improves processing efficiency, reduces material handling costs, and is highly practical.
[0004] The aforementioned patents achieve effective improvement in processing efficiency and reduction in material transfer costs through the cooperation of components such as mixing tanks, baffles, and cylinders, resulting in high practicality. However, they cannot achieve a better effect of fully mixing the materials. Therefore, we propose a mixing device for producing raw materials for sound-absorbing panels. Utility Model Content
[0005] This invention proposes a mixing device for raw materials in the production of sound-absorbing panels, which solves the problem in related technologies that cannot achieve a better effect of fully mixing materials.
[0006] According to one aspect, at least one embodiment of this disclosure provides a mixing device for producing sound-absorbing panels, comprising: a mixing tank, a rotating shaft rotatably connected to the top of the mixing tank, a tank cover fixedly connected to the circumferential surface of the rotating shaft, and a mixing device provided at the bottom inner side of the mixing tank.
[0007] The thorough mixing device includes a motor, the bottom of which is fixedly connected to the bottom inner side of the mixing tank. A rotating shaft is fixedly connected to the motor's output shaft, and a stirring rod is fixedly connected to the circumferential surface of the rotating shaft. A spring is fixedly connected to the inner side of the mixing tank, one end of which is fixedly connected to a material-gathering plate. A force-bearing rod is fixedly connected to the side of the material-gathering plate, and a push rod is fixedly connected to the circumferential surface of the rotating shaft. This thorough mixing device design, through the motor driving the rotating shaft and stirring rod to rotate, and the cooperation of components such as the spring, material-gathering plate, force-bearing rod, and push rod, helps to ensure that the materials are thoroughly mixed and evenly distributed during the mixing process, thus improving mixing efficiency.
[0008] For example, in at least one embodiment of this disclosure, a mixing device for producing sound-absorbing panels is provided, further comprising: multiple springs are arranged in groups of four, with two groups of springs arranged symmetrically. This arrangement of springs helps improve the stability, reliability, and performance of the system, and plays an important role, especially in mechanical systems that need to withstand large or frequent loads.
[0009] Two material-gathering plates are provided, and the two material-gathering plates are arranged symmetrically opposite each other. The two symmetrically arranged material-gathering plates help to improve the performance, efficiency, and stability of the mixing device, and ensure that the material is uniformly processed during the mixing process.
[0010] Two force-bearing rods are provided, and each force-bearing rod is fixedly connected to the side of one of the two aggregate plates. The design of the force-bearing rods is mainly to support, distribute the load, and enhance stability, ensuring the structural integrity of the aggregate plates and the normal operation of the equipment during operation, thereby improving overall work efficiency and durability.
[0011] The sides of the two force-bearing rods are located on the displacement trajectory of the push rod, and there is a gap between the side of the material-gathering plate and one end of the stirring roller. This design ensures smooth operation of the equipment, optimizes stirring and material flow, reduces friction and wear between components, improves mechanical efficiency, and extends the service life of the equipment.
[0012] The system comprises multiple stirring rollers, arranged in groups of three, with three groups forming a vertical axis array of the circular rotating shafts of the stirring rollers. This design, through the grouping of multiple stirring rollers and the vertical axis array layout, helps to improve stirring efficiency, optimize material flow, enhance equipment stability, and effectively reduce equipment wear and vibration, ensuring the efficient operation of the entire stirring system.
[0013] According to another aspect, at least one embodiment of this disclosure also provides a mixing device for producing sound-absorbing panels, comprising: an automatic feeding device provided on the side of the mixing tank, the automatic feeding device including an inlet located on the side of the mixing tank, a conveying pipe fixedly connected to the side of the inlet, a material box fixedly connected to one end of the conveying pipe, a sliding cover plate slidably connected to the side of the inlet, a force-bearing block fixedly connected to the side of the sliding cover plate, and a striker fixedly connected to the circumferential surface of the rotating shaft. This automatic feeding device design improves the accuracy and efficiency of feeding while reducing manual operation and errors. Through the cooperation of the sliding cover plate, the force-bearing block, the striker, etc., precise control of material input is achieved, thereby optimizing the smoothness of the mixing process and the stability of production.
[0014] For example, in at least one embodiment of this disclosure, a mixing device for producing sound-absorbing panels further includes: the side of the force-bearing block is located on the displacement trajectory of the impact rod; a rotating column is rotatably connected to the top of the material box; and a cover plate is fixedly connected to the circumferential surface of the rotating column. The combination and function of these components are to achieve a certain sealing and protection function for the material in the mechanical system.
[0015] A return spring is fixedly connected to the side of the sliding cover, and one end of the return spring is fixedly connected to the inner side of the mixing tank. The return spring automatically restores the sliding cover to its original position, ensuring the smooth progress of the feeding process and enhancing the automation, ease of operation, and safety of the equipment.
[0016] The diameter of the sliding cover is the same as the diameter of the inlet, and the initial state of the return spring is relaxed. The matching diameter of the sliding cover with the inlet ensures a tight seal, while the relaxed state of the return spring ensures the smoothness and control precision of the sliding cover during operation, and also provides support for the automatic reset of the sliding cover.
[0017] The working principle and beneficial effects of this utility model are as follows:
[0018] 1. This utility model achieves its effect through the coordinated operation of components such as a motor, rotating shaft, stirring roller, material gathering plate, force-bearing rod, and push rod. When the motor is started, it drives the rotating shaft to rotate, which in turn drives the stirring roller to rotate, thus agitating the materials in the mixing chamber. The rotating shaft also drives the push rod to rotate. When the push rod rotates to the side of the force-bearing rod, it causes the force-bearing rod to move horizontally. This horizontal movement of the force-bearing rod causes the material gathering plate to move horizontally, pushing materials that cannot be reached in the corners of the mixing chamber into the mixing range of the stirring roller. This ensures thorough mixing and uniform distribution of the materials during the mixing process, improving mixing efficiency.
[0019] 2. This utility model achieves its goal through the coordinated operation of components such as a motor, rotating shaft, inlet, impact rod, sliding cover, material bin, and force-bearing block. When the motor is started, it drives the rotating shaft to rotate, which in turn drives the impact rod to rotate. The impact rod's rotation pushes the force-bearing block to move horizontally, which in turn drives the sliding cover to move horizontally, exposing the inlet. The material in the material bin then falls into the mixing tank through the conveying pipe for mixing. This improves the accuracy and efficiency of material feeding while reducing manual operation and errors. The coordinated operation of the sliding cover, force-bearing block, and impact rod enables precise control of material input, thereby optimizing the smoothness of the mixing process and the stability of production.

[0031] Example 1
[0032] like Figures 1-5 As shown, it illustrates a mixing device for producing sound-absorbing panels according to an embodiment of the present disclosure, comprising: a mixing tank 1, a rotating shaft 2 rotatably connected to the top of the mixing tank 1, a box cover 3 fixedly connected to the circumferential surface of the rotating shaft 2, and a fully mixing device 4 provided on the inner bottom of the mixing tank 1.
[0033] The thorough mixing device 4 includes a motor 41, the bottom of which is fixedly connected to the bottom inner side of the mixing tank 1. The output shaft of the motor 41 is fixedly connected to a rotating shaft 42, and a stirring rod 43 is fixedly connected to the circumferential surface of the rotating shaft 42. A spring 44 is fixedly connected to the inner side of the mixing tank 1, and a material-gathering plate 45 is fixedly connected to one end of the spring 44. A force-bearing rod 46 is fixedly connected to the side of the material-gathering plate 45, and a push rod 47 is fixedly connected to the circumferential surface of the rotating shaft 42. This thorough mixing device 4, through the motor 41 driving the rotating shaft 42 and stirring rod 43 to rotate, and the cooperation of components such as the spring 44, material-gathering plate 45, force-bearing rod 46, and push rod 47, helps to ensure that the materials are thoroughly mixed and evenly distributed during the mixing process, thus improving mixing efficiency.
[0034] In some examples, multiple springs 44 are also included, with four springs 44 arranged in a group, and the two groups of springs 44 arranged symmetrically. This arrangement of springs 44 helps to improve the stability, reliability, and performance of the system, and plays an important role, especially in mechanical systems that need to withstand large or frequent loads.
[0035] There are two material gathering plates 45, which are symmetrically arranged opposite each other. The two symmetrically arranged material gathering plates 45 help to improve the performance, efficiency, and stability of the mixing device 4, and ensure that the material is uniformly processed during the mixing process.
[0036] Two force-bearing rods 46 are provided, and the two force-bearing rods 46 are fixedly connected to the sides of the two aggregate plates 45 respectively. The design of the force-bearing rods 46 is mainly to support, share the load and enhance stability, so as to ensure the structural integrity of the aggregate plates 45 and the normal operation of the equipment during the operation, thereby improving the overall working efficiency and durability.
[0037] The sides of the two force-bearing rods 46 are located on the displacement trajectory of the push rod 47, and there is a gap between the side of the material-gathering plate 45 and one end of the stirring roller 43. This design ensures smooth operation of the equipment, optimizes the mixing and material flow effect, reduces friction and wear between parts, improves mechanical efficiency, and extends the service life of the equipment.
[0038] Multiple stirring rollers 43 are provided, with three stirring rollers 43 arranged in a group of three, forming a vertical axis array of the three groups of stirring rollers 43 rotating on the shaft 42. This design, through the grouping of multiple stirring rollers 43 and the vertical axis array layout, helps to improve stirring efficiency, optimize material flow, enhance equipment stability, and effectively reduce equipment wear and vibration, ensuring the efficient operation of the entire stirring system.
[0039] For example, as shown in the figure, when the motor 41 is started, the motor 41 drives the rotating shaft 42 to rotate. The rotation of the rotating shaft 42 drives the stirring roller 43 to rotate. The rotation of the stirring roller 43 stirs the material in the mixing tank 1. The rotation of the rotating shaft 42 drives the push rod 47 to rotate. When the push rod 47 rotates to the side of the force rod 46, the push rod 47 drives the force rod 46 to move horizontally. The horizontal movement of the force rod 46 drives the material gathering plate 45 to move horizontally. The horizontal movement of the material gathering plate 45 pushes the material that cannot be stirred in the corner of the mixing tank 1 into the stirring range of the stirring roller 43 for stirring. When the push rod 47 rotates and loses contact with the force rod 46, the spring 44 drives the material gathering plate 45 to return to its horizontal position through its own tension, so as to achieve the effect of the next operation.
[0040] Example 2
[0041] like Figures 1-5As shown, this illustration depicts a mixing device for producing sound-absorbing panels according to another embodiment of this disclosure. The technical solution is largely the same as that of Embodiment 1, so only the differences are described. These differences include: an automatic feeding device 5 is provided on the side of the mixing tank 1. The automatic feeding device 5 includes an inlet 51, which is located on the side of the mixing tank 1. A conveying pipe 52 is fixedly connected to the side of the inlet 51, and a material box 53 is fixedly connected to one end of the conveying pipe 52. A sliding cover plate 54 is slidably connected to the side of the inlet 51, and a force-bearing block 55 is fixedly connected to the side of the sliding cover plate 54. A striker 56 is fixedly connected to the circumferential surface of the rotating shaft 42. This design of the automatic feeding device 5 improves the accuracy and efficiency of feeding while reducing manual operation and errors. Through the cooperation of the sliding cover plate 54, the force-bearing block 55, and the striker 56, precise control of material input is achieved, thereby optimizing the smoothness of the mixing process and the stability of production.
[0042] In some examples, the following are also included: the side of the force-bearing block 55 is located on the displacement trajectory of the impact rod 56, the top of the material box 53 is rotatably connected to the rotating column 57, and the circumferential surface of the rotating column 57 is fixedly connected to the cover plate 58. The combination and function of these components are to achieve a certain sealing and protection function for the material in the mechanical system.
[0043] A reset spring 59 is fixedly connected to the side of the sliding cover 54, and one end of the reset spring 59 is fixedly connected to the inner side of the mixing tank 1. The reset spring 59 automatically restores the sliding cover 54 to its original position, ensuring the smooth progress of the feeding process and enhancing the automation, ease of operation, and safety of the equipment.
[0044] The diameter of the sliding cover 54 is the same as the diameter of the inlet 51, and the initial state of the return spring 59 is relaxed. The fact that the diameter of the sliding cover 54 is the same as that of the inlet 51 ensures that the sliding cover 54 is tightly sealed, while the relaxed state of the return spring 59 ensures the smoothness and control accuracy of the sliding cover 54 during operation, and also provides support for the automatic reset of the sliding cover 54.
[0045] For example, as shown in the figure, when the motor 41 is started, the motor 41 drives the rotating shaft 42 to rotate. The rotation of the rotating shaft 42 drives the impact rod 56 to rotate. The rotation of the impact rod 56 pushes the force block 55 to move horizontally. The horizontal movement of the force block 55 drives the sliding cover plate 54 to move horizontally. The horizontal movement of the sliding cover plate 54 exposes the inlet 51. The material in the material box 53 falls into the mixing box 1 from the inlet 51 through the conveying pipe 52 for mixing. When the force block 55 loses the pushing force of the impact rod 56, the reset spring 59 automatically pulls the force block 55 to return to its horizontal position. The horizontal return of the force block 55 drives the sliding cover plate 54 to return to its horizontal position. The horizontal return of the sliding cover plate 54 closes the inlet 51 and stops the material discharge.
[0046] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
