Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or a connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0020] The inventors discovered in practice that manually pouring liquid is not only time-consuming and labor-intensive, but also prone to affecting the final foaming quality of the sponge due to uncontrollable factors. These uncontrollable factors mainly lead to the following situations: Pouring liquid too quickly or at too high a speed will generate a large number of bubbles, affecting the foaming quality. Since the concentrate will foam within seconds of being poured in, manual pouring can only be done at a fixed point, which can easily lead to uneven distribution of the concentrate after it enters the foaming box, thus affecting the foaming quality. When the concentrate in the bucket is almost empty, it tends to stick to the inside of the bucket. To save material, people often shake the bucket quickly a few times to allow as much concentrate as possible to enter the foaming chamber. However, this will create air bubbles and affect the foaming quality.

[0021] In this regard, such as Figures 1-2 As shown, this application provides a low-carbon sponge foaming device based on mixed materials, including a foaming box 1. Two boxes 2 are rotatably connected to the foaming box 1 via an automatic reset shaft. The automatic reset shaft is implemented using existing technology, such as using a torsion spring to achieve automatic reset. After the boxes 2 are opened, they can be automatically closed by the automatic reset shaft. A fixed frame 5 is fixedly connected to the foaming box 1. A drive mechanism is connected to the fixed frame 5. A slide 8 is slidably connected to the fixed frame 5. The drive mechanism is connected to the slide 8. The drive mechanism is electrically driven and can realize the function of automatically driving the slide 8 to move. Furthermore, an automatic liquid pouring mechanism is connected to the slide 8. The automatic liquid pouring mechanism can move along the length of the foaming box 1 under the drive of the drive mechanism and pour the original liquid into the foaming box 1, so as to realize the function of automatic and uniform liquid pouring and improve the foaming quality and efficiency.

[0022] To achieve stable drive, in a preferred embodiment, in such a way... Figure 2 As shown, the driving mechanism includes a motor 6 and a threaded rod 7. The motor 6 is fixedly connected to the fixed frame 5, and the threaded rod 7 is fixedly connected to the output shaft of the motor 6. The threaded rod 7 is rotatably connected to the fixed frame 5. The slide 8 has a threaded hole, and the threaded rod 7 and the inner wall of the threaded hole are threadedly engaged, thereby realizing that the motor 6 drives the threaded rod 7 to rotate, so that the slide 8 moves along the fixed frame 5. The motor 6 is controlled by an external control terminal.

[0023] To achieve the automatic liquid dispensing function, the following is a preferred setting, such as... Figures 1-4 As shown, a rack 9 is added and fixed to the fixed frame 5. In addition, the automatic liquid pouring mechanism includes a gear 10, a first sprocket 11, a second sprocket 13, a reducer 14 and a liquid tank 15. Gear 10, sprocket 11, sprocket 2 13, and liquid tank 15 are all rotatably connected to the slide 8. Gear 10 and sprocket 11 are fixedly connected to achieve coaxial rotation. Gear 10 and rack 9 mesh to achieve meshing transmission. Sprocket 11 is connected to sprocket 2 13 through linkage chain 12 to achieve synchronous rotation of sprocket 11 and sprocket 2 13. Reducer 14 is fixedly connected to the slide 8. Sprocket 2 13 is fixedly connected to the input shaft of reducer 14. Liquid tank 15 is fixedly connected to the output shaft of reducer 14. Reducer 14 is used to reduce the speed of liquid tank 15. Reducer 14 can be equipped with a planetary gear reduction mechanism to achieve speed reduction.

[0024] To ensure that as much stock solution as possible enters the foaming chamber 1 while minimizing the formation of bubbles, such asFigures 5-6 As shown, the following settings can be made. An inner plate 16, a solid column 17, a curved strip 20 and an iron limiting strip 22 are slidably connected to the inner wall of the liquid barrel 15. A limiting groove 18 is provided on the solid column 17. The curved strip 20 extends to the outside of the liquid barrel 15. A damping slide rail is fixedly connected to the inner wall of the liquid barrel 15. The curved strip 20 is slidably connected to the damping slide rail. The damping slide rail can increase the sliding friction of the curved strip 20, so that the curved strip 20 can maintain its current position at an appropriate time. A transmission strip 21 is rotatably connected to the curved strip 20. The transmission strip 21 and the iron limiting strip 22 are rotatably connected. The iron limiting strip 22 is inserted into the limiting groove 18. A permanent magnet block 24 is fixedly connected to the inner wall of the limiting groove 18. A curved surface block 19 is fixedly connected to the carriage 8. The curved strip 20 can drive the iron limiting strip 22 to move through the transmission strip 21, and the permanent magnet block 24 can generate magnetic suction on the iron limiting strip 22.

[0025] To make the box door 2 close tightly, as Figures 7-9 shown, an extension part is provided on the box door 2, and a lock groove 3 is provided on the extension part. Two permanent magnet lock bars 4 are slidably connected to the foam box 1. A permanent magnet plate 23 is fixedly connected to the carriage 8.

[0026] In addition, a lifting limiting mechanism is provided on the inner wall of the liquid barrel 15, and the lifting limiting mechanism is used to limit the lifting height of the inner plate 16.

[0027] Optionally, a limiting block is fixedly connected to the solid column 17, and the limiting block prevents the solid column 17 from detaching from the liquid barrel 15.

[0028] Optionally, the material of the solid column 17 includes stainless steel. The density of stainless steel is relatively large, and the solid design can enable the solid column 17 to have sufficient impact force to push the inner plate 16.

[0029] The shape of the carriage 8 can be set according to the actual situation. For example, the carriage 8 can be in the shape of a C.

[0030] It should be noted that a side plate is detachably connected to the foam box 1 to facilitate opening the side plate to take out the sponge after foaming is completed.

[0031] Working principle: In the initial state, the two permanent magnet lock bars 4 are respectively inserted into the two lock grooves 3 to lock the two box doors 2. The iron limiting strip 22 is inserted into the limiting groove 18, and the permanent magnet block 24 magnetically connects the iron limiting strip 22. The liquid barrel 15 is located outside the foam box 1.

[0032] The operator adds the original liquid to the inner plate 16 in the liquid barrel 15. The original liquid is preferably formed by mixing bio-based polyether polyol and foaming agent, cell opening agent and other materials. The bio-based polyether polyol is degradable and conforms to the concept of low-carbon environmental protection.

[0033] The motor 6 is turned on to control the rotation of the threaded rod 7, which causes the slide 8 to move along the fixed frame 5. The permanent magnet plate 23 moves above one of the permanent magnet lock bars 4, and the permanent magnet plate 23 attracts the permanent magnet lock bar 4 upwards. The permanent magnet lock bar 4 disengages from the lock groove 3 and releases the lock on the box door 2. The liquid tank 15 pushes open the box door 2 and enters the foaming box 1. During the movement of the slide 8, the rack 9 drives the gear 10 to rotate. The gear 10 drives the sprocket 13 to rotate through the linkage chain 12. After the sprocket 13 is reduced by the reducer 14, it drives the liquid tank 15 to rotate slowly. The liquid tank 15 gradually tilts and pours the raw liquid into the foaming box 1. The liquid tank 15 moves along the length of the foaming box 1 while pouring the raw liquid, so that the raw liquid is evenly distributed in the foaming box 1, improving the foaming quality. In addition, the liquid tank 15 is low in height from the bottom wall of the foaming box 1, which greatly reduces the probability of bubble formation and further improves the foaming quality. After the liquid tank 15 is separated from the door 2, the door 2 is reversed under the action of the automatic reset shaft, and the door 2 is automatically closed. When the permanent magnet plate 23 is separated from the permanent magnet lock bar 4, and the lock groove 3 is aligned with the permanent magnet lock bar 4, the permanent magnet lock bar 4 will fall naturally and insert into the lock groove 3 to automatically lock the door 2.

[0034] Due to the presence of the damping slide rail, the curved surface 20 will not slide due to gravity when the liquid tank 15 rotates.

[0035] Because the inner plate 16 needs to prevent the raw liquid from passing through the gap between the inner plate 16 and the inner wall of the liquid tank 15, the sliding friction between the inner plate 16 and the liquid tank 15 will be relatively large. It is difficult for the inner plate 16 to slide smoothly by gravity alone. At this time, the impact force of the solid column 17 is needed to make the inner plate 16 slide to scrape off the residual raw liquid on the inner wall of the liquid tank 15, as follows: When the liquid tank 15 rotates about 180 degrees, the gear 10 and rack 9 disengage, and the curved surface of the curved surface 20 abuts against the curved surface block 19. The curved surface block 19 pushes the curved surface 20 to slide towards the inner plate 16. The curved surface 20 drives the iron limiting strip 22 to move away from the solid column 17 through the transmission strip 21, thereby causing the iron limiting strip 22 to disengage from the limiting groove 18 and release the limiting of the solid column 17. Under the action of gravity, the solid column 17 falls towards the inner plate 16. The solid column 17 impacts the inner plate 16, causing the inner plate 16 to fall. As the inner plate 16 falls, it scrapes off the remaining raw liquid on the inner wall of the liquid tank 15, preventing waste of raw liquid and greatly reducing the probability of bubble production, further improving foaming quality, and solving the problem that the shaking of traditional technology easily causes bubbles in the raw liquid.

[0036] Then, after the liquid tank 15 pushes the other door 2 to open, the slide 8 leaves the inside of the foaming box 1, and the other door 2 reverses under the action of the automatic reset shaft to achieve automatic closing (the principle is the same as above and will not be described again here), so that the door 2 can limit the foaming of the sponge.

[0037] After foaming is complete, the side panel can be opened to remove the foamed sponge. Then, the reverse motor 6 causes the slide 8 to move in reverse. The slide 8 pushes open one door 2 and enters the foaming box 1. The door 2 closes automatically. The slide 8 pushes open another door 2 and leaves the foaming box 1. The other door 2 closes automatically. The liquid tank 15 reverses about 180 degrees. The solid column 17 moves in reverse under its own gravity. When the solid column 17 moves to the limit position, the limiting groove 18 aligns with the iron limiting strip 22. The permanent magnet 24 magnetically attracts the iron limiting strip 22. The iron limiting strip 22 is inserted into the limiting groove 18 to limit the solid column 17, so as to facilitate subsequent impact operations.

[0038] In summary, this invention achieves automatic opening and closing of the box door 2, improving foaming efficiency. Through the cooperation of the permanent magnet lock bar 4 and the lock groove 3, as well as the magnetic adsorption function of the permanent magnet plate 23, the automatic unlocking and automatic locking of the box door 2 is realized. After the liquid is poured out, the box door 2 is automatically closed under the action of the automatic reset shaft, and the permanent magnet lock bar 4 falls back into the lock groove 3 to achieve automatic locking, avoiding possible lock leakage and misoperation caused by manual operation. This keeps the foaming process of the original liquid in a limited environment, effectively improving the consistency and efficiency of foaming. The system enables automatic movement and constant-speed pouring of the raw liquid, ensuring its uniform distribution within the foaming tank 1 and improving foaming quality. The automatic pouring mechanism allows the liquid tank 15 to tilt slowly and synchronously during movement, achieving a uniform pouring mode that pours liquid while moving. Compared to manual pouring concentrated at a single point, this structure allows the raw liquid to be evenly distributed throughout the entire foaming tank 1, effectively reducing uneven foaming caused by localized accumulation. Furthermore, the lower pouring height significantly reduces the probability of bubble formation, greatly improving the density uniformity and overall foaming quality of the finished sponge. The original liquid in the inner wall of the liquid tank 15 is automatically scraped off, reducing waste and reducing the generation of bubbles. The solid column 17 generates a gravitational impact after the iron limit strip 22 is released from the limit groove 18, which causes the inner plate 16 to scrape off the residual original liquid in the inner wall, so that most of the residual original liquid enters the foaming box 1. This not only reduces material waste, but also avoids the bubble problem caused by manual shaking, and greatly improves the foaming uniformity and the quality of the finished product. The device automatically resets after foaming, simplifying preparations for the next round of operation and significantly improving foaming production efficiency. The liquid tank 15 has a large opening, and the residual liquid on the inner wall is easy to clean later. It is not as easy to clog and difficult to maintain as other existing liquid injection nozzle systems. The device enables fully automatic, uniform, high-quality, and efficient liquid pouring, replacing traditional manual operation and greatly improving foaming efficiency and quality.

Although the present invention 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 the present invention without departing from the essence and scope of the technical solutions of the present invention.
