[0001] The utility model relates to the technical field of polystyrene production, in particular to a low-energy consumption production device for foamed polystyrene. Background Art

[0002] With the continuous development of society and the continuous advancement of science and technology, polystyrene is a polymer synthesized from styrene monomers through free radical condensation reaction. It is a colorless and transparent thermoplastic plastic. Polystyrene is the largest used in my country and the world. It has the characteristics of hardness, transparency, rigidity, electrical insulation, low moisture absorption and excellent processing performance. According to different uses, polystyrene is mainly divided into general-purpose polystyrene, impact-resistant polystyrene and foamed polystyrene.

[0003] When using the existing low-energy production device for expanded polystyrene, workers need to pour polystyrene particles into the material chamber and then discharge them through the discharge device. However, this discharge method may cause polystyrene particles to accumulate at the discharge port and cause blockage. Workers need to clear the discharge port before they can continue the discharge work, which will increase the workers' workload and reduce production efficiency. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] The terms "upper", "lower", "left", "right", "middle" and "one" used in the present invention are only for the convenience of description and are not intended to limit the scope of application of the present invention. Changes or adjustments to their relative relationships shall be deemed to be within the scope of application of the present invention without substantially changing the technical content.

[0023] Reference Figures 1-4 A low-energy production device for expanded polystyrene includes a reaction chamber 1 and a bracket 2. The two brackets 2 are fixedly connected to the outer surface of the reaction chamber 1. A vibrating blanking component is installed on the bracket 2 on the upper side. The vibrating blanking component includes a material chamber 3, a rotating shaft 5, a movable plate 15, and a fixed plate 16. The material chamber 3 is fixedly connected to the bracket 2 on the upper side. The rotating shaft 5 is rotatably connected to one end of the material chamber 3. The movable plate 15 is slidably connected to the outer surface of the rotating shaft 5. There is a large friction between the movable plate 15 and the rotating shaft 5. The two fixed plates 16 are fixedly connected to the upper surface of the movable plate 15. A plurality of cylinders 17 are installed on the upper surface of the fixed plate 16 in an annular array. There is an impact member slidably connected in the cylinder 17. Rod 18, the end of the impact rod 18 away from the cylinder 17 is arc-shaped, and a straight spring is provided between the impact rod 18 and the bottom wall of the cylinder 17. The elastic force of the straight spring is relatively large. The two ends of the movable plate 15 are respectively fixedly connected with a buffer chamber 20. The buffer chamber 20 is a non-enclosed space. A pull plate 22 is slidably connected in the buffer chamber 20. A buffer spring 21 is fixedly connected between the pull plate 22 and the inner wall of the buffer chamber 20. A round rod 23 is fixedly connected to the outer surface of the pull plate 22. The round rod 23 is slidably connected in the buffer chamber 20. The round rod 23 drives the pull plate 22 to move first, and the pull plate 22 pulls the buffer spring 21 to deform. When the buffer spring 21 reaches a certain deformation, the buffer spring 21 slowly pulls the movable plate 15 to move.

[0024] A partition 19 is fixedly connected to the material chamber 3, and a moving chamber 9 is fixedly connected to the lower surface of the partition 19. A stopper 8 is slidably connected to the moving chamber 9. The size of the stopper 8 is slightly larger than the discharge port. A square groove is provided on the bottom wall of the moving chamber 9. A push plate 10 is fixedly connected to the lower surface of the stopper 8. The push plate 10 is slidably connected in the square groove. The push plate 10 is threadedly connected to the rotating shaft 5. The push plate 10 is fixedly connected to the round rod 23. A foaming agent box 14 is fixedly connected to the lower side bracket 2. The foaming agent box 14 is filled with polystyrene foaming agent. One side wall of the foaming agent box 14 is rotatably connected to a straight rod 4. A transmission belt 6 is sleeved between the straight rod 4 and the rotating shaft 5. A slide is provided in the foaming agent box 14. A baffle plate 11 is slidably connected in the slide. A rack 12 is fixedly connected to the upper surface of the baffle plate 11, and the end of the straight rod 4 close to the rack 12 is fixedly connected to the gear 1 3. The gear 13 is meshed with the rack 12. A water outlet is provided on the side wall of the foaming agent box 14 near the baffle 11. A plurality of arc blocks are installed in a linear array on the lower surface of the partition 19. An inclined plate 24 is fixedly connected to the bottom wall of the material chamber 3. The inclined plate 24 is arranged in a right-angled trapezoid. The reaction chamber 1 is connected to the material chamber 3 through a square tube 25. The reaction chamber 1 is connected to the foaming agent box 14 through a water outlet pipe 26. The upper surface of the reaction chamber 1 is fixedly connected to the air inlet pipe 7. The end of the air inlet pipe 7 away from the reaction chamber 1 is connected to the material chamber 3. The air inlet pipe 7 can introduce the high-temperature gas in the reaction chamber 1 into the material chamber 3 to preheat the polystyrene particles in the material chamber 3, so that the polystyrene particles have a certain temperature when entering the reaction chamber 1, thereby reducing the heating time of the reaction chamber 1, reducing energy loss, and achieving the purpose of low energy consumption.

[0025] In the present invention, the shaft 5 is driven to rotate by an external servo motor connected to the shaft 5, and the push plate 10 on the shaft 5 moves, and the push plate 10 pushes the block 8 to slide. At this time, the discharge hole on the partition 19 is exposed, and the polystyrene particles fall onto the inclined plate 24, and then roll from the inclined plate 24 through the square tube 25 into the reaction chamber 1. The rotation of the shaft 5 drives the straight rod 4 to rotate through the transmission belt 6, and the rotation of the straight rod 4 drives the gear 13 to rotate, and the rotation of the gear 13 drives the rack 12 to rotate, and the rotation of the rack 12 drives the baffle 11 to move. The movement of the baffle 11 exposes the water outlet hole on the side wall of the foaming agent box 14, so that the foaming agent in the foaming agent box 14 enters the reaction chamber 1 through the water outlet pipe 26, completing the function of automatic unloading and adding foaming agent.

[0026] When the rotating shaft 5 rotates, the push plate 10 starts to move, and the push plate 10 drives the round rod 23 to move, and the round rod 23 drives the pull plate 22 to move, and the pull plate 22 starts to pull the buffer spring 21, and the buffer spring 21 is deformed. When the push plate 10 moves to a certain position, the pulling force of the buffer spring 21 is greater than the friction force between the movable plate 15 and the rotating shaft 5. At this time, the buffer spring 21 pulls the movable plate 15 to move slowly, and the movable plate 15 moves slowly to drive the fixed plate 16 to move. The movement of the fixed plate 16 causes the cylinder 17 to move, and the arc block on the partition 19 squeezes the impact rod 18, and the impact rod 18 is pressed to move toward the lower end of the cylinder 17. The impact rod 18 squeezes the straight spring in the cylinder 17, and when the impact rod 18 passes through the arc block, the straight spring resets the impact rod 18, causing the impact rod 18 to hit the lower surface of the partition 19, thereby causing the material chamber 3 to vibrate, preventing polystyrene particles from blocking the discharge port.

[0027] In the present invention, unless otherwise clearly specified or limited, the terms “installed”, “connected”, “connected”, “fixed” and the like should be understood in a broad sense.

[0028] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
