Description

A closed-cell sound-insulating sponge gradient pressure foaming preparation device Technical Field

[0001] This utility model relates to the technical field of sponge preparation equipment, and in particular to a closed-cell sound-insulating sponge gradient pressure foaming preparation device. Background Technology

[0002] In modern industrial production and daily life, closed-cell sound-insulating foam is widely used in many fields such as construction, automobile manufacturing, and electronic equipment due to its excellent sound insulation, heat insulation, and cushioning properties. Its performance largely depends on the process and equipment used in the foaming preparation stage.

[0003] For current foaming preparation devices, the existing sponge foaming device disclosed in patent number "CN214294104U" uses horizontal and vertical rods to form a stirring and foaming mechanism that closely adheres to the inner wall. The vertical rods can better utilize the material adhered to the inner wall, resulting in more uniform stirring. However, the stirring part of this device is fixed in a designated position and can only rotate in one direction. In actual foaming, as the reaction progresses, the physical properties of the sponge material change dynamically: initially, when the viscosity is low, unidirectional stirring can meet basic mixing requirements; however, in the middle and later stages, the material viscosity increases and the volume expands, making it difficult for this device to handle complex flow patterns. It cannot switch directions to overcome local viscous resistance, easily leading to stirring dead zones and uneven mixing.

[0004] Accordingly, this application proposes a closed-cell sound-insulating sponge gradient pressure foaming preparation device. Summary of the Invention

Detailed Implementation

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0039] Referring to Figures 1 to 5, a closed-cell sound-insulating sponge gradient pressure foaming preparation device includes a foaming barrel 1, an mounting frame 2 fixedly connected to the top surface of the foaming barrel 1, a rotating rod 3 rotatably connected to the foaming barrel 1, the rotating rod 3 being rotatably connected to the mounting frame 2, a pressure plate 4 slidably connected to the rotating rod 3, the side wall of the pressure plate 4 being in contact with the inner wall of the foaming barrel 1, so that when the pressure plate reciprocates, it will simultaneously clean the deposits on the bottom inner wall of the foaming barrel 1.

[0040] A sleeve rod 41 is symmetrically fixedly connected to the inner surface of the foaming tank 1. A spring 42 is fixedly connected to the inner wall of the sleeve rod 41. A sliding rod 43 is fixedly connected to the end of the spring 42 away from the sleeve rod 41. The sliding rod 43 is fixedly connected to the pressure plate 4.

[0041] A block-shaped stirring rod 5 is slidably connected to the rotating rod 3. A retaining strip is axially arranged on the outer surface of the rotating rod 3. A through groove matching the retaining strip is correspondingly arranged on the inner wall of the central hole of the block-shaped stirring rod 5. The retaining strip and the through groove are slidably engaged. When the rotating rod 3 rotates, the block-shaped stirring rod 5 rotates synchronously through the meshing action of the retaining strip and the through groove. When the block-shaped stirring rod 5 moves up and down under the drive of the moving component, the through groove slides along the retaining strip, ensuring that the block-shaped stirring rod 5 maintains rotational motion while achieving axial displacement. A discharge valve 6 is provided on the foaming tank 1.

[0042] A closed-cell sound-insulating sponge gradient pressure foaming preparation device also includes a stirring assembly and a moving assembly. The stirring assembly is used to stir the sponge material in the foaming tank 1. The stirring assembly includes a motor 31, a placement plate 32, an electric push rod 33, a connecting block 34, a support rod 35, and a stirring blade 36. The motor 31 is fixedly connected to the top surface of the mounting frame 2, and the output end of the motor 31 is fixedly connected to the rotating rod 3. The placement plate 32 is fixedly connected to the rotating rod 3, and the interior of the placement plate 32 is hollow. The electric push rod 33 is symmetrically fixedly connected to the inner wall of the placement plate 32. The connecting block 34 is fixedly connected to the output end of the electric push rod 33. The support rod 35 is fixedly connected to the bottom end of the connecting block 34. The stirring blade 36 is fixedly connected to the support rod 35. The side of the stirring blade 36 fits the shape of the inner wall of the foaming tank 1. When the stirring blade 36 moves to fit the inner wall of the foaming tank 1 and rotates, it will scrape off the adhering material on the inner wall of the foaming tank 1, reducing material waste. At the same time, the inner wall of the foaming tank 1 can be cleaned after use.

[0043] The moving assembly is used to drive the block-shaped stirring rod 5 to move up and down inside the foaming tank 1. The moving assembly includes a cam 51, a first gear 52, a threaded rod 53, a second gear 54, and a connecting rod 55. The cam 51 is fixedly connected to the block-shaped stirring rod 5 and is fixedly connected to the rotating rod 3. The first gear 52 is fixedly connected to the rotating rod 3. The threaded rod 53 is rotatably connected to the inner wall of the mounting frame 2. The second gear 54 is rotatably connected to the inner wall of the mounting frame 2. The threaded rod 53 is threadedly connected to the second gear 54, and the connecting rod 55 is threadedly connected to the threaded rod 53. The convex disc 51 has a cavity inside, and the connecting rod 55 is placed on the inner wall of the cavity. The connecting rod 55 is slidably connected to the mounting frame 2 and the foaming tank 1. The connecting rod 55 has a protrusion that matches the cavity structure. When the convex disc 51 rotates, it can rotate along the connecting rod 55 through the cavity. At the same time, the protrusion supports the connecting rod 55. Driven by the threaded rod 53, the connecting rod 55 will synchronously drive the convex disc 51 and the block-shaped stirring rod 5 to move on the rotating rod 3.

[0044] In this invention, the required materials are first placed into the foaming tank 1. At this time, the motor 31 starts and drives the rotating rod 3 to rotate. The rotating rod 3 rotates the placement plate 32. The electric push rod 33 inside the placement plate 32 will intermittently push the connecting block 34 to move as the placement plate 32 rotates, thereby driving the bottom support rod 35 and the stirring blade 36 to move. This makes the stirring area of ​​the stirring blade 36 in the foaming tank 1 gradually increase. When the stirring blade 36 is in contact with the inner wall of the foaming tank 1, it will scrape off the attached material on the inner wall of the foaming tank 1 to prevent it from accumulating into lumps.

[0045] At the same time, the rotation of the rotating rod 3 drives the first gear 52 to rotate. The first gear 52 meshes with the second gear 54, driving the second gear 54 to rotate. The rotation of the second gear 54 causes the threaded rod 53 to rotate. The rotation of the threaded rod 53 drives the connecting rod 55 to move up and down. Since the connecting rod 55 is placed in the cavity of the convex plate 51, it drives the block stirring rod 5 to move up and down in the foaming tank 1, realizing the up and down stirring of the sponge material.

[0046] As the block-shaped stirring rod 5 continues to move downward, it will come into contact with the pressure plate 4 at the bottom. The pressure plate 4 will move downward under force, and drive the sliding rod 43 to squeeze the spring 42 inside the sleeve rod 41. When the pressure plate 4 moves downward, it applies gradient pressure to the sponge material to meet different foaming requirements. When the block-shaped stirring rod 5 moves upward, it will drive the pressure plate 4 to reset under the action of the spring 42. During the reset process, the two sides of the pressure plate 4 will scrape off the attached material on the bottom inner wall of the foaming tank 1.

[0047] After foaming is complete, open discharge valve 6 to discharge the prepared closed-cell sound insulation sponge.

[0048] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
