[0023] 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0024] A rubber raw material mixing machine, such as Figures 1-5 As shown, the machine includes a body 1, inside which a mixing chamber 4 is provided. A feeding port 3 is provided on the front side of the body 1, which is connected to the mixing chamber 4. A sealing seat 6 is slidably connected to the top of the inner wall of the mixing chamber 4. A motor 7 is fixedly connected to the middle of the upper end of the sealing seat 6. A stirring rod 8 is fixedly connected to the output end of the motor 7. A paddle 9 is fixedly connected to the side wall of the stirring rod 8. A bracket 17 is snapped onto the side wall of the stirring rod 8 at the upper end of the paddle 9. A scraper 18 is fixedly connected to the lower end of the bracket 17. The scraper 18 cooperates with the scraper on the inner wall of the mixing chamber 4.
[0025] The width of the feeding port 3 is the same as the diameter of the mixing chamber 4. An outlet communicating with the mixing chamber 4 is provided at the rear end of the machine body 1. The outer diameter of the bracket 17 is slightly smaller than the inner diameter of the mixing chamber 4. The scraper 18 fits into the inside of the mixing chamber 4. The bracket 17 is installed by snap-fit, which is convenient for disassembly and assembly.
[0026] Raw materials are added into the mixing chamber 4 through the feeding port 3. The sealing seat 6 slides down to close the mixing chamber 4. The motor 7 (model 110ST-M05030) drives the stirring rod 8 to rotate, so that the blade 9 stirs the raw materials inside the mixing chamber 4. At the same time, the stirring rod 8 drives the bracket 17 to rotate, so that the scraper 18 scrapes against the inner wall of the mixing chamber 4 to remove the raw materials adhering to the chamber wall, so that the raw materials are mixed evenly. The stirring structure is simple, the surface is smooth, and it is easy to clean. The bracket 17 and the scraper 18 can be disassembled for easy replacement and cleaning.
[0027] like Figures 2-5 As shown, a retaining ring 16 is fixedly connected to the middle of the bracket 17, and a fixing seat 12 is fixedly connected to the side wall of the stirring rod 8 at the position above the blade 9. The retaining ring 16 is fastened to the side wall of the stirring rod 8 by bolts. The retaining ring 16 is located at the upper end of the fixing seat 12. A driving assembly is slidably connected to the side wall of the stirring rod 8, and the driving assembly is inserted into the retaining ring 16.
[0028] The fixed seat 12 restricts the retaining ring 16 to prevent it from sliding down. The retaining ring 16 is installed by bolts. To prevent the retaining ring 16 from rotating relative to the stirring rod 8, a drive assembly is installed on the stirring rod 8. The stirring rod 8 drives the drive assembly to rotate, and the drive assembly drives the bracket 17 to rotate.
[0029] like Figures 2-5 As shown, the drive assembly includes a socket 14, a sliding groove 13 is provided on the side wall of the stirring rod 8, a locking block is fixedly connected to the inner wall of the socket 14, the locking block is slidably connected in the sliding groove 13, and multiple sets of inserts 15 are fixedly connected to the lower end of the socket 14, and the multiple sets of inserts 15 are all inserted and engaged with the upper end of the retaining ring 16.
[0030] When installing the retaining ring 16, first slide the socket 14 upward to place the retaining ring 16 on the side wall of the stirring rod 8 at the upper end of the fixed seat 12. After adjusting the position of the retaining ring 16, tighten it with bolts. Then slide the socket 14 downward to insert the insert post 15 into the retaining ring 16. When the stirring rod 8 rotates, the stirring rod 8 drives the socket 14 to rotate. The socket 14 drives the retaining ring 16 to rotate through the insert post 15, thereby rotating the bracket 17 and scraping the inner wall of the mixing chamber 4 with the scraper 18.
[0031] like Figures 1-5 As shown, a notch 19 is provided on one side of the bracket 17, and the bolt fastening part of the retaining ring 16 is directly opposite the notch 19. The length of the notch 19 is greater than the diameter of the stirring rod 8.
[0032] When the bolts are removed, the retaining ring 16 opens, the retaining ring 16 and the stirring rod 8 separate, and the tilted bracket 17 can be removed from the mixing chamber 4.
[0033] like Figure 1 As shown, a hydraulic cylinder 2 is fixedly connected to the top of the machine body 1. The output end of the hydraulic cylinder 2 is located in the mixing chamber 4, and a lifting seat 5 is fixedly connected to the output end of the hydraulic cylinder 2. A sealing seat 6 is fixedly connected to the lower end of the lifting seat 5, and a motor 7 is located between the lifting seat 5 and the sealing seat 6.
[0034] The output end of hydraulic cylinder 2 (model HOB-FA) drives the lifting seat 5 to rise and fall, which in turn drives the sealing seat 6 to rise and fall, indirectly driving the sealing seat 6 to rise and fall, thus providing installation space for motor 7.
[0035] like Figures 2-3 As shown, the number of blades 9 is arranged in multiple sets. Each pair of blades 9 in the same vertical plane is fixed with a side wing 10. The side wings 10 are provided with extrusion ports 11, and the areas of the extrusion ports 11 are different.
[0036] The rotation of blade 9 drives the side wing 10 to extrude the raw material, and the extrusion port 11 extrudes the raw material, which has a repeated granulation function for the raw material and increases the mixing effect of the raw material.
[0037] The working principle of the rubber raw material mixing machine provided by this utility model is as follows:
[0038] Raw materials are added into the mixing chamber 4 through the feeding port 3. The hydraulic cylinder 2 drives the lifting seat 5 to descend, causing the sealing seat 6 to slide down and close the mixing chamber 4. The motor 7 drives the stirring rod 8 to rotate, causing the blade 9 and the side wings 10 to stir the raw materials inside the mixing chamber 4. At the same time, the stirring rod 8 drives the bracket 17 to rotate, causing the scraper 18 to scrape against the inner wall of the mixing chamber 4 to remove the raw materials adhering to the chamber wall, so that the raw materials are mixed evenly. The stirring structure is simple, the surface is smooth, and it is easy to clean. The bracket 17 and the scraper 18 can be disassembled for easy replacement and cleaning.
[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
