[0002] Two-stage foaming experiments are a crucial step in studying the foaming process of polymer materials. By controlling the injection of the foaming agent and the foaming process, precise control over the material's density and pore structure can be achieved. This experiment is essential for developing high-performance foam materials because it can simulate and optimize the foaming behavior in actual production processes, thereby improving material performance and reducing costs.

[0003] The existing two-stage foaming experimental equipment with multiple pelletizing modules is an advanced experimental device that integrates multiple pelletizing modules to adapt to different experimental conditions and material properties. This equipment achieves precise control of the foaming process by precisely controlling the injection amount of foaming agent and the foaming time.

When it is necessary to process particles of different sizes and shapes, these devices may not be able to provide sufficient adjustment range, leading to deviations in experimental results. Therefore, this application provides a two-stage foaming experimental device with multiple pelletizing modules. Utility Model Content

[0033] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0034] This application discloses a two-stage foaming experimental device with multiple pelletizing modules.

[0035] Reference Figure 1 , Figure 2 and Figure 5 A two-stage foaming experimental device with multiple pelletizing modules includes a support frame 1. A foaming chamber 2 is fixedly connected to the top of the support frame 1. A heating pipe 3 is fixedly connected through one side of the foaming chamber 2. A feeding pipe 4 is fixedly connected to one end of the heating pipe 3. A feeding hopper 5 is fixedly connected to the top of the feeding pipe 4. A motor 6 is fixedly connected to one end of the feeding pipe 4. An auger 7 is rotatably connected inside the feeding pipe 4. The output end of the motor 6 is fixedly connected to one end of the auger 7. A connecting pipe 10 is fixedly connected through one side of the foaming chamber 2. A second foaming chamber 11 is fixedly connected to one end of the connecting pipe 10. A stirring assembly is installed inside both the first and second foaming chambers 11. The bottom of the second foaming chamber 11 is fixedly connected to... A transmission pipe 12 is connected to a motor 13 fixedly connected to one end of the transmission pipe 12. An auger 14 is rotatably connected inside the transmission pipe 12. The output end of the motor 13 is fixedly connected to one end of the auger 14. A support plate 15 is fixedly connected to the top of the support frame 1. One end of the auger 14 is fixedly connected inside the support plate 15. A baffle 16 is fixedly connected to one side of the support plate 15. A cutting component is installed inside the baffle 16. An adjustment component is installed on one side of the support plate 15. A collection box 17 is fixedly connected to one end of the support frame 1. An insulation pipe 8 is fixedly connected to the outer wall of the heating pipe 3. An electric heating pipe 9 is fixedly connected inside the insulation pipe 8. The electric heating pipe 9 is located between the heating pipe 3 and the insulation pipe 8.

[0036] Secondly, the cutting assembly includes a motor 29 fixedly connected to one side of the baffle 16. Multiple blades 30 are fixedly connected to the output end of the motor 29. A baffle plate 27 is fixedly connected inside one end of the transmission tube 12. An extrusion plate 28 is rotatably connected inside one end of the transmission tube 12. One side of the baffle plate 27 is attached to one side of the extrusion plate 28. The extrusion plate 28 has extrusion holes of various shapes.

[0037] In operation, the material to be foamed is first fed into the feeding pipe 4 through the feeding hopper 5. Then, motor 6 is started to drive auger 7. The rotation of auger 7 slowly feeds the material to be foamed into the heating pipe 3. At this time, multiple electric heating tubes 9 are started by an external controller. The material is preheated by the continuous heating of multiple electric heating tubes 9 until the material reaches the predetermined initial temperature. Then, it is fed into the foaming chamber 2 through auger 7 for the first foaming. After foaming is completed, the material can be fed into the second foaming chamber 11 through the connecting pipe 10 for a more refined second foaming. During the foaming process in foaming chambers 12 and 11, the internal stirring components can be started to uniformly stir and heat the material, thereby improving the foaming efficiency and ensuring the uniformity and consistency of the foaming process. After the material in the second foaming chamber 11 has finished foaming, it will enter the auger 14. At this time, motor 13 is started to drive the support plate. The support plate 15 rotates, pushing the foamed material forward after foaming. The material then passes through the baffle plate 27, causing it to be extruded through the extrusion holes on the extrusion plate 28. The motor 29 then rotates, driving the blade 30 to rotate. The high-speed rotation of the blade 30 uniformly cuts the extruded material. When the cutting shape and size need to be changed, the adjustment component can be activated to adjust the position of the extrusion holes of different shapes and sizes on the extrusion plate 28. The material is then cut again to generate foamed particles of the desired shape and size, which finally fall into the collection box 17. The adjustment component effectively improves the flexibility and practicality of the experimental equipment, meeting different cutting requirements and preventing deviations in experimental results. This improves the accuracy and stability of the foaming experiment, maintaining consistent foaming effects under different conditions. It greatly simplifies the operation process, increases work efficiency, reduces the need for manual intervention, and can quickly adapt to various experimental needs, expanding the equipment's application range.

[0038] Reference Figure 1 and Figure 3The stirring assembly includes a motor 3 18 fixedly connected to the top of foaming chamber 1 2 and foaming chamber 2 11. A stirring shaft 19 is rotatably connected inside both foaming chamber 1 2 and foaming chamber 2 11. The output end of motor 3 18 is fixedly connected to one end of stirring shaft 19. Multiple stirring blades 20 are evenly fixedly connected to stirring shaft 19. An infrared heating module 21 is fixedly connected to the bottom of stirring shaft 19. A temperature sensor 26 is fixedly connected to the top surface inside both foaming chamber 1 2 and foaming chamber 2 11. The infrared heating module 21 is electrically connected to the temperature sensor 26. Grooves 22 are opened at both ends of multiple stirring blades 20. Springs 23 are fixedly connected inside multiple grooves 22. Sealing blocks 24 are slidably connected inside multiple grooves 22. One end of multiple springs 23 is fixedly connected to one end of multiple sealing blocks 24 respectively. A scraper 25 is fixedly connected to the other end of multiple sealing blocks 24.

[0039] In operation, motor 18 is first started to drive the stirring shaft 19 to rotate, causing multiple stirring blades 20 to rotate inside foaming chambers 1-2 and 2-11, continuously stirring the foamed material. Simultaneously, the infrared heating module 21 continuously heats the interior of foaming chambers 1-2 and 2-11, and the temperature sensor 26 monitors the temperature inside these chambers in real time for timely adjustments. This ensures uniform stirring and heating of the material during the foaming process, improving efficiency. The foaming efficiency ensures uniformity and consistency during the foaming process. In addition, during the rotation of the stirring blades 20, the elasticity of the spring 23 pushes the sealing block 24 forward, thereby pushing the scraper 25 to adhere to the inner wall of foaming chamber 1 2 and foaming chamber 2 11. The rotation of multiple stirring blades 20 can drive the scraper 25 to continuously scrape the inner wall of foaming chamber 1 2 and foaming chamber 2 11, thereby keeping the inner wall of foaming chamber 1 2 and foaming chamber 2 11 clean and reducing the situation where material sticks to the inner wall of foaming chamber 1 2 and foaming chamber 2 11.

[0040] Reference Figure 1 , Figure 4 and Figure 5 The adjustment assembly includes a groove 31 formed on the outer wall of one end of the transmission pipe 12, a slider 32 fixedly connected to the outer wall of the extrusion plate 28, the slider 32 being slidably connected in the groove 31, and an electric telescopic rod 33 hinged to one side of the support plate 15, the output end of the electric telescopic rod 33 being hinged to one end of the slider 32.

[0041] In use, the electric telescopic rod 33 is first activated to move the slider 32 at one end, thereby causing the slider 32 to slide inside the groove 31. Guided by the groove 31, the extrusion plate 28 rotates, thereby adjusting the position of the discharge hole on the extrusion plate 28. Then, cutting is performed to generate foamed particles of the required shape and size. Adjusting the extrusion plate 28 can effectively improve the flexibility and practicality of the experimental equipment, meet different cutting requirements, avoid deviations in experimental results, improve the accuracy and stability of foaming experiments, maintain consistent foaming effects under different conditions, greatly simplify the operation process, improve work efficiency, reduce the need for manual intervention, and quickly adapt to various types of experimental needs, thus expanding the application range of the equipment.

[0042] The implementation principle of this embodiment of a two-stage foaming experimental device with a multi-particle module is as follows: In use, the material to be foamed is first fed into the feeding pipe 4 through the feeding hopper 5. Then, motor 6 is started to drive the auger 7. The rotation of the auger 7 slowly feeds the material to be foamed into the heating pipe 3. At this time, multiple electric heating tubes 9 are started by an external controller. The material is preheated by the continuous heating of the multiple electric heating tubes 9 until the material reaches the predetermined initial temperature. Then, it is fed into the foaming chamber 2 through the auger 7 for initial foaming. After foaming is complete, the material can be fed into the second foaming chamber 11 through the connecting pipe 10 for a more refined secondary foaming. During the foaming process in both the first and second foaming chambers 11, motor 3 18 is started to drive the stirring shaft 19 to rotate, causing multiple stirring blades 20 to rotate inside the first and second foaming chambers 11. The material being foamed is continuously stirred, and the infrared heating module 21 continuously heats the interior of foaming chamber 11 and foaming chamber 21. The temperature sensor 26 monitors the temperature inside foaming chamber 11 and foaming chamber 21 in real time and makes timely adjustments. This allows for uniform stirring and heating of the material during the foaming process, thereby improving foaming efficiency and ensuring uniformity and consistency. In addition, as the stirring blades 20 rotate, the elasticity of the spring 23 pushes the sealing block 24 forward, which in turn pushes the scraper 25 to adhere to the inner wall of foaming chamber 11 and foaming chamber 21. The rotation of multiple stirring blades 20 drives the scraper 25 to continuously scrape the inner wall of foaming chamber 11 and foaming chamber 21, thereby keeping the inner wall of foaming chamber 11 and foaming chamber 21 clean and reducing the amount of material sticking to the inner wall of foaming chamber 11 and foaming chamber 21.

[0043] Secondly, after the material inside the foaming chamber 11 has finished foaming, it enters the auger 14. At this time, the motor 13 is started to drive the support plate 15 to rotate, pushing the foamed material forward. After passing through the baffle plate 27, the material is completely extruded through the extrusion holes on the extrusion plate 28. Then, the motor 29 is started to drive the blade 30 to rotate, and the high-speed rotation of the blade 30 uniformly cuts the extruded material. When it is necessary to change the cutting shape and size of the material according to the requirements, the electric telescopic rod 33 can be started to drive the slider 32 at one end to move, thereby moving the slider 32 within the groove 31. The material slides, and guided by the chute 31, the extrusion plate 28 rotates, thereby adjusting the position of the discharge hole on the extrusion plate 28. Then, it is cut to generate foamed particles of the required shape and size, which finally fall into the collection box 17. Adjusting the extrusion plate 28 can effectively improve the flexibility and practicality of the experimental equipment, meet different cutting requirements, avoid deviations in experimental results, improve the accuracy and stability of foaming experiments, maintain consistent foaming effects under different conditions, greatly simplify the operation process, improve work efficiency, reduce the need for manual intervention, and quickly adapt to various types of experimental needs, thus expanding the application range of the equipment.
