Description

Technical Field

[0001] This utility model relates to the field of silicone production technology, and in particular to a kneading machine for silicone production. Background Technology

[0002] Silica gel, also known as silica gel, is an amorphous material with highly active adsorption properties. Its core component is silicon dioxide, characterized by strong chemical stability and non-flammability. Kneaders are ideal devices for processing high-viscosity, elasto-plastic materials, suitable for kneading, mixing, vulcanizing, and polymerizing various materials such as silicone rubber, sealants, hot melt adhesives, food adhesive matrices, and pharmaceutical formulations. As an indispensable special mixing and stirring equipment in the silicone rubber manufacturing process, the kneader plays a crucial role.

[0003] Existing silica gel kneaders face several technical challenges when processing masterbatches, primarily in terms of poor mixing uniformity. Since masterbatches typically contain multiple components, the proportions of each component have a crucial impact on the performance of the final product, thus requiring a highly uniform mixing process. However, current equipment appears unable to adequately meet this requirement, resulting in compromised product consistency and quality stability.

[0004] Furthermore, during the raw material input process, operators must frequently use electronic scales for precise weighing to ensure formula accuracy. While this ensures the correct ingredient ratios for each batch, it also increases the workload for workers, making the entire production process exceptionally cumbersome. This not only reduces production efficiency but may also introduce more human error due to frequent manual operations. Utility Model Content

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0023] A kneading machine for silicone production, such as Figures 1-6 As shown, the system includes a fixed base frame 1, a discharge machine 2, a kneader body 3, a mixing mechanism, a feed pipe 9, an electronic scale 10, a weighing hopper 11, a control module 14, and a feeding mechanism. The discharge machine 2, which is a screw discharge machine, is fixedly connected to the top of the fixed base frame 1. The kneader body 3 is fixedly connected to the top of the discharge machine 2. A mixing mechanism for mixing solid and liquid raw materials is connected to the top of the kneader body 3. Two feed pipes 9 are connected to the mixing mechanism. The top of each feed pipe 9 is connected to the electronic scale 10 and the feeding mechanism. The electronic scale 10 has a feeding hole in the middle, which is connected to the feed pipe 9. The control module 14 is installed on the front of each electronic scale 10 and is electrically connected to the control module 14. The weighing hopper 11 is fixedly connected to the top of each electronic scale 10, and a gap is left between the bottom of the weighing hopper 11 and the electronic scale 10. During silicone production, solid raw materials are poured into the left weighing hopper 11 and liquid raw materials are poured into the right weighing hopper 11. After being weighed by the electronic scale 10, the solid and liquid raw materials are discharged from their respective weighing hoppers 11 through the feeding mechanism and fall into the mixing mechanism through the feeding pipe 9. The mixing mechanism thoroughly mixes the solid and liquid raw materials, and then the mixed materials enter the kneading machine body 3 for kneading. After kneading is completed, the silicone is sent out through the discharge machine 2. This eliminates the need for multiple manual weighings each time and improves the accuracy of weighing.

[0024] like Figures 1-3As shown, the mixing mechanism includes a mixing tank 4, a mixing rod 6, a servo motor 7, a transparent plate 8, and a first valve 5. The mixing tank 4 is fixedly connected to the top of the kneader body 3 and is connected to the kneader body 3. The mixing tank 4 is connected to two feed pipes 9, which are located at the top of the mixing tank 4. The servo motor 7 is installed on the top of the mixing tank 4, and the output shaft of the servo motor 7 passes through the outer wall of the mixing tank 4. The mixing rod 6 is fixedly connected to the output shaft of the servo motor 7 and is located inside the mixing tank 4. An observation hole is opened on the front side of the mixing tank 4, and a transparent plate 8 is fixedly connected inside the observation hole, allowing observation of the mixing of solid and liquid raw materials in the mixing tank 4. The first valve 5 is rotatably connected at the connection between the mixing tank 4 and the kneader body 3, and the handle of the first valve 5 passes through the outer wall of the connection.

[0025] When using the mixing mechanism, the first valve 5 is in the closed state. The servo motor 7 drives the mixing rod 6 to rotate, thereby mixing the raw materials in the mixing tank 4. After the solid and liquid raw materials are mixed, the first valve 5 is manually turned to open it, so that the mixed raw materials fall into the kneader body 3 for kneading processing, thereby ensuring the consistency and quality stability of the silicone products.

[0026] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, the feeding mechanism includes an electric slide rail 12 and a baffle plate 13. The electric slide rail 12 is fixedly connected to both the front and rear sides of the electronic scale 10. The electric slide rail 12 is electrically connected to the control module 14. Two baffle plates 13 are slidably connected to the bottom of the weighing hopper 11. The sliders of the front and rear electric slide rails 12 are connected to the left and right baffle plates 13. The baffle plates 13 are located in the gap between the bottom of the weighing hopper 11 and the electronic scale 10. The baffle plates 13 are used to block the feed pipe 9 and the feeding hole of the electronic scale 10. The electronic scale 10 weighs the sum of the weight of all parts on the electronic scale 10 and the weight of the raw material. The control module 14 tare the value weighed by the electronic scale 10, that is, subtract the weight of all parts on the electronic scale 10, so as to obtain the weight of the raw material. The control module 14 then adjusts the weight of the raw material required for each feeding. When the raw material reaches the required weight, the control module 14 controls the electric slide rail 12 to move the baffles 13 on it away from each other, so that the raw material in the weighing bucket 11 can fall into the mixing bucket 4, thereby completing the accurate weighing and feeding. After feeding is completed, the electric slide rail 12 drives the baffles 13 on it to move closer to each other and reset, in preparation for the next feeding operation.

[0027] like Figure 4 and Figure 5As shown, the outer diameter of the baffle plate 13 is larger than the inner diameter of the weighing hopper 11. When the left and right baffle plates 13 are far apart, they can prevent the raw material from falling onto the outside of the bottom of the weighing hopper 11, ensuring the cleanliness of the kneader, reducing material waste, and improving the quantitative accuracy of feeding.

[0028] like Figure 1 , Figure 3 , Figure 4 and Figure 6 As shown, it also includes a fixed rod 15, a loading tank 16, a second valve 17, a gear 18, and a rack 19. The top of the mixing tank 4 is fixedly connected to two fixed rods 15, and the loading tank 16 is fixedly connected to each fixed rod 15. The bottom of the loading tank 16 is rotatably connected to the second valve 17, and the handle of the second valve 17 passes through the bottom outer wall of the loading tank 16. The slider of the electric slide rail 12 is fixedly connected to the rack 19, and the second valve 17 is fixedly connected to the gear 18, which meshes with the rack 19. Initially, the second valve 17 is open. When pouring raw materials into the weighing hopper 11, the solid and liquid materials are first poured into the left and right loading hoppers 16 respectively. The solid and liquid materials fall into the left and right weighing hoppers 11 respectively. When the solid and liquid materials reach the required weight, the left and right baffles 13 are moved away from each other by the electric slide rail 12. Under the meshing action of the gear 18 and rack 19, the gear 18 rotates and drives the second valve 17 to rotate, thereby closing the second valve 17. The raw materials in the loading hopper 16 can no longer fall into the weighing hopper 11, further realizing the accurate weighing of raw materials. A large amount of raw materials can be stored in the loading hopper 16. The automatic feeding of this kneader is realized through the control module 14, improving the processing efficiency.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit the scope of protection of this utility model. 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 solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
