[0024] Please see Figure 1-6 This utility model provides a technical solution:
[0025] A raw material mixing and heating device based on polyurethane resin composite material includes a support plate 1 and a servo motor 2. The servo motor 2 is fixedly connected to one side of the support plate 1. A connecting column 3 is fixedly connected to the end of the main shaft of the servo motor 2. A mixing shell 4 is fixedly connected to one side of the connecting column 3. A piston 5 is provided at the lower end of the mixing shell 4. A mixing groove 6 is opened on the inner side of the mixing shell 4. An ear seat fixing plate 7 is fixedly connected to one side of the mixing shell 4. An upper cover plate 8 is fixedly connected to one side of the ear seat fixing plate 7. A stepper motor 9 is fixedly connected to the top of the upper cover plate 8. A connecting inner plate is fixedly connected to the end of the main shaft of the stepper motor 9. 10. A stirring rod 11 is rotatably connected to the inner side of the inner plate 10. A gear 12 is fixedly connected to the top of the stirring rod 11. An inner shell 13 is fixedly connected to one side of the stirring rod 11. The inner side of the mixing shell 4 is in contact with one side of the scraper 14. A limited rotation cylinder 15 is fixedly connected to the lower end of the stirring rod 11. The lower end of the limited rotation cylinder 15 is rotatably connected to the inner side of the limited rotation groove 16. The limited rotation groove 16 is opened inside the outer rotating ring 17. A rubber sealing ring 18 is fixedly connected to the outer side of the outer rotating ring 17. An inner rotating ring 19 is fixedly connected to the inner side of the outer rotating ring 17. A rack ring 20 is fixedly connected to the inner side of the upper cover plate 8.
[0026] As a further implementation of this solution, a cylindrical hole is opened on the inner side of the support plate 1. The outer side of the main shaft of the servo motor 2 rotates inside the cylindrical hole of the support plate 1. There are two connecting rotating columns 3. The rear connecting rotating column 3 is rotatably connected to the inner side of the support plate 1, so that when the servo motor 2 rotates, it drives the connecting rotating column 3 to rotate, thereby facilitating the disassembly of the upper cover plate 8 and the mixing shell 4, and facilitating the cleaning of the scraper 14, stirring rod 11 and inner hollow shell 13.
[0027] As a further implementation of this scheme, the mixing shell 4 is in the shape of a hollow cylinder. A hollow cylinder is fixedly connected to the inside of the mixing shell 4. The inner side of the inner rotating ring 19 is in contact with the outer side of the cylinder of the mixing shell 4. The rubber sealing ring 18 is in contact with the inner side of the mixing shell 4 to improve the stability of the rotation of the stirring rod 11. At the same time, after the outer rotating ring 17 and the inner rotating ring 19 are moved out of the mixing shell 4, the raw materials inside the mixing shell 4 are scraped out.
[0028] As a further implementation of this solution, a groove is provided on the inner side of the lower end of the upper cover plate 8, and a cylindrical hole is provided on the inner side of the upper cover plate 8. The main shaft of the stepper motor 9 rotates inside the cylindrical hole of the upper cover plate 8, which facilitates the rotation of the main shaft of the stepper motor 9 inside the upper cover plate 8.
[0029] As a further implementation of this solution, the connecting inner plate 10 is movable in the groove at the lower end of the upper cover plate 8. A cylindrical hole is opened on the inner side of the connecting inner plate 10. There are two sets of rotation-limiting cylinders 15, with two cylinders in each set. Each set of rotation-limiting cylinders 15 is fixed to the upper and lower ends of the stirring rod 11. The stirring rod 11 is rotatably connected to the inner side of the connecting inner plate 10 through the rotation-limiting cylinders 15. Heating wires are provided on the inner side of the stirring rod 11 and the scraper 14 to facilitate the connecting inner plate 10 to move inside the upper cover plate 8 and to facilitate the rotation of the gear 12.
[0030] As a further implementation of this scheme, the number of gears 12 is not less than two. The outer side of gear 12 meshes with the inner side of rack ring 20. Rack ring 20 is composed of multiple racks, which makes gear 12 rotate when it is meshed with rack ring 20.
[0031] As a further implementation of this scheme, a solid gravity column 21 is slidably connected to the inner side of the inner shell 13, a sealing ring 22 is fixedly connected to the inner side of the inner shell 13, a spring 23 is fixedly connected to one side of the solid gravity column 21, a middle disc 24 is fixedly connected to the inner side of the inner shell 13, a balloon 25 is fixedly connected to the inner side of the middle disc 24, the inner side of the middle disc 24 is hollow, the inner side of the inner shell 13 is hollow, and the solid gravity column 21 is shaped as a solid cylinder at both ends. When the stirring rod 11 rotates, under the action of centrifugal force, the solid gravity column 21 slides out of the inner shell 13, thereby causing the scraper 14 to adhere to the inner wall of the mixing shell 4.
[0032] Workflow: During use, the device is powered by an external power source. When mixing the raw materials inside the mixing groove 6, the upper cover plate 8 is separated from the mixing shell 4. The raw materials are placed inside the mixing groove 6, and the servo motor 2 is started, driving the connecting rotating column 3 to rotate. The connecting rotating column 3 drives the mixing shell 4 to rotate, at which point the upper cover plate 8 faces upward. The stepper motor 9 is then started, and the rotation of the stepper motor 9 drives the connecting inner plate 10, which is fixedly connected to the end of the main shaft, to rotate. The rotation of the connecting inner plate 10 drives the stirring roller 11, which is connected to the rotation-limiting cylinder 15, to rotate around the main shaft of the stepper motor 9. The rotation of gear 12 drives gear 12 to rotate. The outer side of gear 12 meshes with rack ring 20. When gear 12 rotates, gear 12 itself rotates, driving stirring rod 11 to rotate around itself. The lower end of stirring rod 11 drives outer rotating ring 17 to rotate through rotation-limiting cylinder 15. Rotation-limiting cylinder 15 is rotatably connected to the inner side of rotation-limiting groove 16, which limits the rotation of cylinder 15. The rotation of outer rotating ring 17 drives inner rotating ring 19, which is fixedly connected to the inner side, to rotate. Rubber sealing ring 18 is fixedly connected to the inner side of inner rotating ring 19, while rubber sealing ring 18 is fixed to the outer side of outer rotating ring 17. The sealing ring 18, a rubber sealing ring 18, seals the outer rotating ring 17, the mixing shell 4, and the inner rotating ring 19. When the stirring roller 11 rotates, it drives the inner hollow shell 13 to rotate. The rotation of the inner hollow shell 13 drives the solid gravity column 21, which is slidably connected to the inner side, to rotate. The solid gravity column 21 is slidably connected to the inner side of the inner hollow shell 13. The inner hollow shell 13 is fitted to the outer side of the solid gravity column 21 through the sealing ring 22, thus sealing the space between the inner hollow shell 13 and the solid gravity column 21 and preventing raw materials from entering the interior of the inner hollow shell 13. When the inner hollow shell 13 rotates, the solid gravity column 21 is subjected to centrifugal force... Under the action, the solid gravity column 21 slides out of the inner hollow shell 13. The solid gravity column 21 drives the spring 23 fixedly connected on one side to deform. The spring 23 has the effect of resetting the solid gravity column 21. At this time, the gas inside the balloon 25 enters the space between the middle disk 24 and the solid gravity column 21. At the same time, one end of the inner hollow shell 13 is under-pressured, which facilitates the resetting of the solid gravity column 21 when idle. The movement of the solid gravity column 21 causes the scraper 14 fixedly connected on one side to stick to the inner side of the mixing shell 4, thereby scraping the raw materials on the inner wall of the mixing shell 4 and improving the mixing uniformity.
[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
