Description

Technical Field

[0001] This utility model relates to the field of ingredient mixing, specifically a silicone sealant ingredient mixing device. Background Technology

[0002] In the production and processing of silicone sealants, ingredient mixing is a crucial step that determines product quality. The core requirement is to achieve uniform dispersion and mixing of various raw materials, while avoiding material waste, batch contamination, and increased equipment maintenance costs caused by residues on the inner walls of the mixing container. However, currently available conventional silicone sealant mixing equipment still has some shortcomings in practical applications, making it difficult to meet the demands of efficient and high-quality production.

[0003] From the perspective of mixing effect, traditional devices mostly adopt a mixing structure with a single shaft and fixed blades, and the mixing trajectory is relatively fixed, which can only perform preliminary stirring of the material in the middle area of ​​the container. Traditional mixing devices generally lack an effective barrel cleaning mechanism. During the mixing process, high-viscosity silicone raw materials are easy to adhere to the inner wall of the mixing barrel, especially at the junction of the barrel wall and bottom and the edge areas that the mixing blades cannot reach. The residual material will gradually accumulate and solidify. Therefore, it is necessary to design a silicone rubber batching and mixing device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a silicone sealant mixing device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a silicone sealant mixing device, comprising a mixing tank, a lid hopper mounted on the top of the mixing tank by bolts, feed pipes on both sides of the lid hopper, feed hoppers fixedly mounted on the top of the feed pipes, two discharge pipes at the bottom of the mixing tank, electric valves fitted on the outside of the discharge pipes, a mixing component inside the mixing tank, and a feeding component at the bottom of the two discharge pipes.

[0006] Preferably, the mixing assembly includes a rotating motor fixedly installed on the top of the lid, one end of the rotating motor being fixedly connected to a first rotating shaft, a first limiting bearing being fixedly installed on the bottom inner side of the mixing tank, one end of the first rotating shaft being rotatably connected to the first limiting bearing, a fixing rod being respectively fitted on the outer side of the first rotating shaft near both ends, multiple sets of stirring blades being provided between the two fixing rods, each set of stirring blades including two, the stirring blades being spiral-shaped, and an inner wall cleaning assembly being provided on the outer side of the first rotating shaft near the fixing rod.

[0007] Preferably, the feeding assembly includes a feeding barrel fixedly installed at the bottom of two discharge pipes. A speed-regulating motor is fixedly installed at one end of the feeding barrel, and a second rotating shaft is fixedly connected to one end of the speed-regulating motor. A second limiting bearing is fixedly installed at one end of the inner side of the feeding barrel. The second rotating shaft is rotatably connected to the second limiting bearing. An agitator plate is fitted on the outer side of the second rotating shaft. The agitator plate is spiral-shaped. A discharge pipe is fixedly connected to one end of the feeding barrel.

[0008] Preferably, the inner wall cleaning assembly includes connecting rods respectively fitted on the outside of the first rotating shaft and close to the two fixed rods, with support rods fixedly connected between the two ends of the two connecting rods, and multiple scrapers fitted on the outside of the support rods.

[0009] Preferably, a connecting pipe is fixedly installed above the discharge pipe, the top end of the connecting pipe is fixedly connected to one of the inlet pipes, a valve is fitted on the outside of the connecting pipe near the bottom, and a pump is fitted on the middle of the outside of the connecting pipe.

[0010] Preferably, the outer side of the feeding hopper is provided with a cleaning hole, and the top of the cleaning hole is covered with a sealing cap.

[0011] Preferably, the outer side of the feeding hopper is fitted with multiple heating rings, and the outer side of the multiple heating rings is provided with a heat insulation layer.

[0012] Preferably, one of the connecting rods has multiple stirring rods at its bottom.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. The dual inlet design allows for the simultaneous separate input of various silicone sealant raw materials. The hopper design expands the inlet area, preventing spillage during the feeding process. The specially designed mixing components inside the mixing tank can specifically mix the silicone sealant raw materials to address their viscous properties. The electric valve can precisely control the discharge switch and discharge speed, allowing for flexible adjustment of the discharge volume according to subsequent process requirements. This prevents the raw materials from accumulating and clogging due to a large amount of material discharged at once. It also ensures sealing and pressure maintenance during the mixing process, preventing external impurities from affecting the purity of the raw materials.

[0014] 2. The rotating motor drives the first rotating shaft to rotate, and in conjunction with the first limit bearing, the first rotating shaft remains stable during high-speed rotation, avoiding mixing deviation caused by shaft wobbling. The spiral stirring blade structure is designed to address the viscous and easily agglomerated characteristics of silicone sealant raw materials. It can form an up-and-down convection mixing trajectory during rotation, which not only expands the mixing coverage area, but also generates stronger shearing and extrusion effects on the raw materials, completely breaking up the raw material agglomerates. This allows the raw materials of each component to achieve all-round, dead-angle-free, and uniform mixing in the mixing tank. The inner wall cleaning component can rotate synchronously with the first rotating shaft. During the mixing process, the cleaning component can adhere to the inner wall of the mixing tank in real time, scraping off the silicone sealant raw materials adhering to the tank wall and bringing them back to the mixing area.

[0017] 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.

[0018] Example 1 Please refer to Figure 1-5As shown, this utility model provides a silicone sealant mixing device, including a mixing tank 1, a lid 2 bolted to the top of the mixing tank 1, feed pipes 3 on both sides of the lid 2, a feed hopper 4 fixedly installed on the top of the feed pipes 3, two discharge pipes 5 at the bottom of the mixing tank 1, an electric valve fitted on the outside of the discharge pipes 5, a mixing component inside the mixing tank 1, and a feeding component at the bottom of the two discharge pipes 5.

[0019] Specifically, the two inlets allow for the simultaneous separate input of various silicone sealant raw materials. The design of the feed hopper 4 increases the inlet area, preventing raw materials from spilling during the feeding process. The specially designed mixing components inside the mixing tank 1 can specifically mix the silicone sealant raw materials to address their viscous characteristics. The electric valve can precisely control the discharge switch and discharge speed, allowing for flexible adjustment of the discharge volume according to the needs of subsequent processes to prevent the raw materials from accumulating and clogging due to a large amount of material discharged at once. It can also achieve sealing and pressure maintenance during the mixing process to prevent external impurities from entering and affecting the purity of the raw materials.

[0020] The mixing component includes a rotating motor 6 fixedly installed on the top of the lid 2. One end of the rotating motor 6 is fixedly connected to a first rotating shaft 7. A first limiting bearing 8 is fixedly installed on the bottom inner side of the mixing tank 1. One end of the first rotating shaft 7 is rotatably connected to the first limiting bearing 8. Fixing rods 9 are respectively fitted on the outer side of the first rotating shaft 7 and near both ends. Multiple sets of stirring blades 10 are provided between the two fixing rods 9. Each set of stirring blades 10 includes two blades. The stirring blades 10 are spiral-shaped. An inner wall cleaning component is provided on the outer side of the first rotating shaft 7 and near the fixing rods 9.

[0021] More specifically, the rotating motor 6 drives the first rotating shaft 7 to rotate, and in conjunction with the first limiting bearing 8, the first rotating shaft 7 remains stable during high-speed rotation, avoiding mixing deviations caused by shaft wobbling. The spiral stirring blade 10 structure is designed to address the viscous and easily agglomerated characteristics of silicone raw materials, and can form an up-and-down convection mixing trajectory during rotation. This not only expands the mixing coverage area, but also generates stronger shearing and squeezing effects on the raw materials, completely breaking up the raw material agglomerates, allowing all components to achieve all-round, dead-angle-free uniform mixing within the mixing tank 1. The inner wall cleaning component can rotate synchronously with the first rotating shaft 7. During the mixing process, the cleaning component can adhere to the inner wall of the mixing tank 1 in real time, scraping off the silicone raw materials adhering to the tank wall and bringing them back to the mixing area.

[0022] As should be added, the feeding assembly includes a feeding hopper 11 fixedly installed at the bottom of the two discharge pipes 5. A speed-regulating motor 12 is fixedly installed at one end of the feeding hopper 11, and a second rotating shaft 13 is fixedly connected to one end of the speed-regulating motor 12. A second limiting bearing 14 is fixedly installed at one end of the inner side of the feeding hopper 11. The second rotating shaft 13 is rotatably connected to the second limiting bearing 14. An agitator 15 is fitted on the outer side of the second rotating shaft 13. The agitator 15 is spiral-shaped. A discharge pipe 16 is fixedly connected to one end of the feeding hopper 11. A cleaning hole 22 is provided on the outer side of the feeding hopper 11. A sealing cap 23 is provided on the top of the cleaning hole 22. Multiple heating rings 24 are fitted on the outer side of the feeding hopper 11. A heat insulation layer 25 is provided on the outer side of the multiple heating rings 24. A connecting pipe 20 is fixedly installed above the discharge pipe 16. The top end of the connecting pipe 20 is fixedly connected to one of the inlet pipes 3. A valve is fitted on the outer side of the connecting pipe 20 near the bottom. A pump 21 is fitted on the middle of the outer side of the connecting pipe 20.

[0023] Furthermore, the speed-regulating motor drives the second rotating shaft 13 to rotate, which, in conjunction with the second limit bearing 14 inside the feeding barrel 11, ensures the stable rotation of the second rotating shaft 13. The spiral stirring plate 15 can convey the mixed silicone raw material when rotating, which not only avoids the viscous silicone from clogging during the feeding process, but also allows the sealing cover 23 to be opened directly to clean the inner wall of the feeding barrel 11 when the equipment is stopped for maintenance. It can also control the temperature of the heating ring 24 according to the viscosity of the material to heat the material, which can effectively prevent solidification and clogging in the feeding barrel 11 due to temperature drop. The heat insulation layer 25 can not only prevent heat loss, but also prevent workers from being burned by touching it. If the mixing is not thorough, the raw material in the discharge pipe can be extracted by the pump 21 and put back into the feed pipe for mixing again.

[0024] The inner wall cleaning assembly includes connecting rods 17 respectively fitted on the outside of the first rotating shaft 7 and close to the two fixed rods 9. Support rods 18 are fixedly connected between the two ends of the two connecting rods 17. Multiple scrapers 19 are fitted on the outside of the support rods 18. Multiple stirring rods 26 are provided at the bottom of one of the connecting rods 17.

[0025] Furthermore, the connecting rod 17 rotates synchronously with the first rotating shaft 7, driving the support rod 18 between the two connecting rods 17 and the multiple scrapers 19 on the outside of the support rod 18 to rotate against the inner wall of the mixing tank 1. The scrapers 19 are arranged in two sets at intervals. The scrapers 19 can accurately scrape off the viscous silicone adhesive material adhering to the tank wall, avoiding the formation of stubborn stains due to long-term residual curing of the material. The scraped material is brought back to the mixing area, making full use of the material and reducing production costs. The mixing rod 26 can perform secondary mixing on the material at the bottom of the mixing tank 1, which can effectively avoid the situation where some materials are not mixed sufficiently.

[0026] Working principle: First, the raw materials to be mixed are fed into the mixing tank 1 through the feed pipe 3, and the rotating motor 6 is started. The rotating motor 6 drives the first rotating shaft 7 to rotate. At the same time, the first rotating shaft 7 rotates, driving the fixed rod 9 and the connecting rod 17 to rotate. The fixed rod 9 drives the stirring blade 10 to stir and mix the materials. At the same time, the connecting rod 17 drives the support rod 18 and the scraper 19 to scrape the inner wall of the mixing tank 1, removing the raw materials adhering to the inner wall of the mixing tank 1 and bringing them back to the mixing area for continued stirring. Meanwhile, the stirring rod 26 stirs the materials. The material at the bottom of the bucket 1 is stirred a second time. Then, the stirred material is discharged into the feeding bucket 11 through the discharge pipe 5. The speed-regulating motor 12 is started, which drives the second rotating shaft 13 to rotate and drives the stirring plate 15 to transport the material forward. Finally, the heating ring 24 is started to heat the material, and the material is discharged through the discharge pipe 16 to enter the next process. The material that is not thoroughly stirred can be extracted from the discharge pipe by the suction pump 21 and re-entered into the feeding pipe to be stirred again with the raw material.
