[0001] This utility model relates to the field of organosilicon foam material preparation technology, specifically to a multifunctional foaming device for preparing organosilicon foam materials. Background Technology

[0002] Silicone foam materials are widely used in aerospace, electronic packaging, and construction due to their excellent high-temperature resistance, insulation, and flexibility. Their preparation process requires precise control of the foaming reaction to achieve a porous structure. Temperature uniformity is a core factor affecting foaming efficiency and finished product quality. Traditional foaming equipment often uses jacketed heating or bottom heating plates, which have low heat transfer efficiency and are prone to localized overheating, significantly impacting the foaming effect. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the above-mentioned technical difficulties and provide a multifunctional foaming device for the preparation of organosilicon foam materials, which can uniformly heat the raw materials during the foaming reaction process, greatly improving the foaming effect.

[0004] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a multifunctional foaming device for preparing organosilicon foam materials, comprising a cabinet, an installation hole at the upper end of the cabinet, a foaming tank inserted into the installation hole, a sealing cover plate installed on the foaming tank, support arms slidably connected to both sides of the cabinet, a detachable fixing frame fixedly connected to the upper end of the support arms on both sides, a reciprocating mechanism for driving the support arms on both sides to move up and down, a stirring cylinder rotatably connected to the bottom surface of the fixing frame, an movable hole in the center of the sealing cover plate that mates with the stirring cylinder, a connecting piece arranged in a circular array fixedly connected to the bottom surface of the stirring cylinder, at least one heating ring arranged coaxially with the stirring cylinder fixedly connected to the connecting piece, at least one stirring shaft arranged in a circular array rotatably connected to the outer wall of the stirring cylinder, a through hole that mates with the stirring shaft on the heating ring, stirring blades fixedly connected to the outer wall of the stirring shaft, and a control mechanism for driving the stirring shaft to rotate synchronously inside the stirring cylinder.

[0005] As an improvement, the reciprocating mechanism includes lifting sleeves fixedly connected to both sides of the cabinet, the support arms on both sides being slidably inserted into the lifting sleeves, a return spring cooperating with the support arm being fixedly connected to the bottom surface of the lifting sleeve, a rack being fixedly connected to one side of the support arm, an adjustment hole cooperating with the rack being provided on one side of the lifting sleeve, a first motor being fixedly connected to the outer wall of the lifting sleeve, and an incomplete gear meshing with the rack being fixedly connected to the output end of the first motor.

[0006] As an improvement, the control mechanism includes a driven bevel gear rotatably connected to the inner wall of the stirring drum to drive the stirring shaft to rotate, a rotating shaft rotatably connected to the center of the stirring drum, a driving bevel gear meshing with the driven bevel gear fixedly connected to the lower end of the rotating shaft, and a second motor fixedly connected inside the stirring drum to drive the rotating shaft to rotate.

[0007] As an improvement, a support plate is fixedly connected to the upper end of each of the two support plates on opposite sides, and a fixing bolt is threaded to both ends of the fixing frame. The support plate is provided with a fixing screw hole that mates with the fixing bolt.

[0008] As an improvement, a limiting ring is fixedly connected to the upper end of the foaming tank, a limiting block is fixedly connected to the bottom surface of the limiting ring, and a limiting slot that mates with the limiting block is provided at the upper end of the cabinet.

This combined motion allows the heating coils to dynamically and comprehensively contact the foaming material, significantly improving heat transfer efficiency and completely eliminating the problems of localized overheating or heating dead zones caused by static heating or unidirectional heating in traditional equipment. This ensures uniform temperature distribution throughout the foaming tank. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0017] like Figures 1 to 4 As shown, a multifunctional foaming device for preparing organosilicon foam materials includes a cabinet 1. The upper end of the cabinet 1 is provided with a mounting hole 13, into which a foaming tank 2 is inserted. A sealing cover plate 21 is installed on the foaming tank 2. A limit ring 22 is fixedly connected to the upper end of the foaming tank 2. A limit block 23 is fixedly connected to the bottom surface of the limit ring 22. The upper end of the cabinet 1 is provided with a limit slot 24 that cooperates with the limit block 23. Support arms 3 are slidably connected to both sides of the cabinet 1. A detachable fixing frame 4 is fixedly connected to the upper end of the support arms 3 on both sides. A support plate 27 is fixedly connected to the opposite side of the upper end of the support plate on both sides. Fixing bolts 28 are threaded to both ends of the fixing frame 4. Fixing screw holes that cooperate with the fixing bolts 28 are provided on the support plate 27.

[0018] The cabinet 1 is provided with a reciprocating mechanism that drives the support arms 3 on both sides to move up and down. The reciprocating mechanism includes lifting sleeves 8 fixedly connected to both sides of the cabinet 1. The support arms 3 on both sides are slidably inserted into the lifting sleeves 8. The bottom surface of the lifting sleeves 8 is fixedly connected with a return spring 11 that cooperates with the support arm 3. A rack 7 is fixedly connected to one side of the support arm 3. An adjustment hole 12 that cooperates with the rack 7 is provided on one side of the lifting sleeve 8. A first motor 9 is fixedly connected to the outer wall of the lifting sleeve 8. An incomplete gear 10 that meshes with the rack 7 is fixedly connected to the output end of the first motor 9.

[0019] The bottom surface of the fixed frame 4 is rotatably connected to a stirring drum 5, and the upper end of the fixed frame 4 is fixedly connected to a third motor 6 that drives the stirring drum 5 to rotate. At least one stirring plate 20 is fixedly connected to the outer wall of the stirring drum 5. A sealing cover plate 21 has a movable hole at its center that mates with the stirring drum 5. A connecting piece 15 arranged in a circular array is fixedly connected to the bottom surface of the stirring drum 5. At least one heating coil 14, coaxially arranged with the stirring drum 5, is fixedly connected to the connecting piece 15. At least one stirring shaft 16 arranged in a circular array is rotatably connected to the outer wall of the stirring drum 5. The ring 14 is provided with a through hole that mates with the stirring shaft 16. The stirring shaft 16 is fixedly connected to the outer wall of the stirring blade 17. The stirring cylinder 5 is provided with a control mechanism that drives the stirring shaft 16 to rotate synchronously. The control mechanism includes a driven bevel gear 26 that is rotatably connected to the inner wall of the stirring cylinder 5 to drive the stirring shaft 16 to rotate. A rotating shaft 18 is rotatably connected to the center of the stirring cylinder 5. A driving bevel gear 25 that meshes with the driven bevel gear 26 is fixedly connected to the lower end of the rotating shaft 18. A second motor 19 that drives the rotating shaft 18 to rotate is fixedly connected inside the stirring cylinder 5.

[0020] In practical use, the foaming tank 2 containing the silicone foaming raw material is inserted into the mounting hole 13 by aligning the limiting plug 23 at the bottom of the tank with the limiting slot 24 at the top of the cabinet 1 and securing it to ensure stable placement. The sealing cover 21 is then placed on top, the heating coil 14 is started for preheating, the third motor 6 is started to drive the stirring drum 5 to rotate around its axis, the second motor 19 is started to drive the rotating shaft 18 to rotate, and through the meshing of the driving bevel gear 25 and the driven bevel gear 26, all the stirring shafts 16 inside the heating coil 14 and the stirring blades 17 thereon are driven to rotate. The first motor 9 is started to drive the incomplete gear 10 to rotate. When the teeth of the incomplete gear 10 mesh with the rack 7, they push the support arm 3 upward against the force of the return spring 11. When the toothless part of the incomplete gear 10 rotates to the position of the rack 7, the support arm 3 moves downward under the action of the return spring 11. This cycle repeats, enabling the support arm 3, the fixed frame 4, and the entire mixing drum 5 assembly to move up and down reciprocally within the foaming tank 2. The rotation of the mixing drum 5 drives the mixing plate 20 to macroscopically mix the materials. The rotation of multiple mixing shafts 16 drives the mixing blades 17 on them to finely shear and mix the materials. Multiple coaxial heating coils 14 work in conjunction with the mixing plate 20 and the mixing blades 17, and their heat can be dynamically, three-dimensionally, and omnidirectionally transferred to materials at different heights and radial positions. The lifting motion allows the heating coils 14 and the mixing blades 17 to cover the entire height range of the foaming tank 2, avoiding uneven heating at the top and bottom, ensuring rapid and uniform heat transfer and thorough mixing of the reaction components, thereby obtaining a uniform foaming environment.

[0021] After the reaction is complete, remove the fixing bolts 28 on the fixing frame 4, remove the fixing frame 4 and the stirring assembly, open the sealing cover 21, and take out the foaming tank 2 that has completed foaming to obtain uniform, high-quality organosilicon foam material.
