Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0022] Sponge materials are widely used in furniture, packaging, automotive interiors, medical supplies, and sound and heat insulation. The resilience of sponges greatly affects the user experience, but currently, sponge foaming devices do not have pre-detection functions.

[0023] To enable pre-testing of the resilience performance of sponges and significantly reduce the failure rate of subsequent manual testing of the resilience performance of cut sponges, the following technical measures are implemented.

[0024] like Figures 2-9 As shown, an environmentally friendly and energy-saving sponge foaming device based on carbon dioxide foaming agent includes a conveyor belt device 1, a support 2 fixedly connected to the conveyor belt device 1, a plate drive mechanism 5 connected to the support 2, a pressure plate 3 slidably connected to the support 2, the pressure plate 3 and the plate drive mechanism 5 are connected, and a sponge pre-detection mechanism is provided on the pressure plate 3.

[0025] The sponge pre-inspection mechanism can be used to automatically pre-inspect the resilience performance of foamed sponges without cutting them. The pressure plate 3 is used to pre-compress, shape, and stabilize the foam during foaming, and also serves as the mounting carrier for the sponge pre-inspection mechanism. Specifically, the pressure plate 3 moves along the support 2 under the drive of the plate drive mechanism 5, applying controllable pressure and limiting force to the foamed sponge, making the sponge surface more flat and the thickness more uniform, improving the foaming quality, and providing a basis for the subsequent automatic pre-inspection of resilience performance by the sponge pre-inspection mechanism.

[0026] Preferably, the bracket 2 includes multiple vertical sections and one horizontal section to provide mounting support for other components.

[0027] For a further configuration of the sponge pre-detection mechanism, the sponge pre-detection mechanism includes a test cylinder 6, a steel ball 19, and a reciprocating drive mechanism; The test cylinder 6 is fixed to the pressure plate 3. The test cylinder 6 is equipped with an intelligent sensor system. The bottom wall of the test cylinder 6 is flush with the bottom wall of the pressure plate 3. A ball control mechanism is movably connected to the test cylinder 6. The ball control mechanism is connected to the steel ball 19. The reciprocating drive mechanism is connected to the bracket 2. The reciprocating drive mechanism is connected to the ball control mechanism.

[0028] Based on the above scheme, in some embodiments, the ball control mechanism includes a transmission cylinder 16 and a movable magnet 17. The transmission cylinder 16 is slidably connected to the inner wall of the test cylinder 6, and the movable magnet 17 is slidably connected to the inner wall of the transmission cylinder 16. Two or more through holes 18 are opened on the bottom wall of the transmission cylinder 16. The perforation 18 allows the magnetic force of the movable magnet 17 to pass through the transmission cylinder 16 and magnetically attract the steel ball 19.

[0029] The reciprocating drive mechanism includes a movable rack 8, a permanent magnet plate 9, a fixed magnet 10, an automatic winder 12, a gear 13, and a square frame 15. The movable rack 8 is slidably connected to the pressure plate 3, and a movable permanent magnet strip 7 is slidably connected to one end of the movable rack 8. The permanent magnet plate 9 and the fixed magnet 10 are both fixed to the bracket 2. The automatic winder 12 is fixed to the pressure plate 3, and a transmission line 11 is movably connected to the automatic winder 12. One end of the transmission line 11 is fixed to the movable rack 8. The gear 13 is rotatably connected to the pressure plate 3 and meshes with the movable rack 8. A protrusion 14 is rotatably connected to the gear 13 and is slidably connected to the inner wall of the square frame 15. The square frame 15 is slidably connected to the pressure plate 3, and the square frame 15 is fixed to the transmission cylinder 16.

[0030] The automatic winder 12 is equipped with a winding mechanism that utilizes the elasticity of the automatic winding transmission line 11. This mechanism can be implemented using existing technology and is not limited here. The gear 13 and the movable rack 8 are linked together, and the protruding column 14 drives the square frame 15 to move up and down.

[0031] To reduce the pull-back speed of the movable rack 8, a damping slide rail 4 is fixedly connected to the pressure plate 3, and the movable rack 8 is slidably connected to the damping slide rail 4.

[0032] To achieve the slow descent of the movable permanent magnet strip 7 under gravity, a damping slide rail 20 is fixedly connected to one end of the movable rack 8, and the movable permanent magnet strip 7 is slidably connected to the damping slide rail 20.

[0033] Damping slide rail 1-4 and damping slide rail 2-20 are both guide slide rails with damping function, which can increase sliding friction and reduce the speed of component reset.

[0034] refer to Figure 8In an optional embodiment of the present invention, the test cylinder 6 has an open structure at the top and bottom to facilitate the movement of the transmission cylinder 16 and the steel ball 19, and the transmission cylinder 16 has an open structure at the top to facilitate the movement of the movable magnet 17.

[0035] refer to Figure 8 To limit the position of the movable magnet 17, the movable magnet 17 is provided with a protrusion, and the inner wall of the transmission cylinder 16 is provided with a groove, with the protrusion slidably connected to the inner wall of the groove.

[0036] It is worth noting that the conveyor belt device 1 is equipped with two side baffles, which can prevent the mixed raw materials from overflowing.

[0037] Specifically, the plate drive mechanism 5 is a cylinder system, and the piston rod of the cylinder system can drive the pressure plate 3 to perform stable lifting and lowering movements.

[0038] Optionally, the bottom wall of the conveyor belt device 1 is provided with anti-slip feet. The anti-slip feet are used to support the conveyor belt device 1 and prevent displacement.

[0039] like Figure 1 As shown, an environmentally friendly and energy-saving sponge foaming process based on carbon dioxide foaming agent, and an environmentally friendly and energy-saving sponge foaming device based on carbon dioxide foaming agent, includes the following steps: Step 1: Mix the carbon dioxide foaming agent with the basic foaming raw materials according to the preset ratio to form a mixed raw material to be foamed. Then, put the mixed raw material into the storage device for later use. Some of the basic foaming raw materials can be made from recycled waste plastics. The advantages of carbon dioxide foaming agent are that it is environmentally friendly, safe and economical. It does not harm human health, does not pollute the environment, has a wide range of sources and low price, which can reduce the overall production cost. Step 2: Drive the pressure plate 3 to a preset height using the plate driving mechanism 5; Step 3: The mixed raw materials in the storage device are quantitatively injected into the surface of the pad paper laid on the conveyor belt device 1 through the injection device, so that the mixed raw materials foam on the pad paper to form a sponge; Step 4: During the conveyor belt device 1's transport of the sponge, the sponge pre-inspection mechanism is used to pre-inspect the sponge.

[0040] Implementation Process: In the initial state of this embodiment, the movable permanent magnet strip 7 is located to the side of the pressure plate 3, and the lower end of the movable permanent magnet strip 7 extends to the lower part of the pressure plate 3. At this time, the bottom wall of the movable magnet 17 abuts against the inner bottom wall of the transmission cylinder 16, and the steel ball 19 is attracted by the magnetic force of the movable magnet 17, and the steel ball 19 abuts against the bottom wall of the transmission cylinder 16. Under the tension of the transmission line 11, the movable rack 8 is pulled back to the initial position and maintains abutment with the automatic winding device 12, thereby putting the entire pre-detection mechanism in the initial working condition ready to be triggered.

[0041] In the specific foaming process, the carbon dioxide foaming agent is first mixed with the basic foaming raw material according to a preset ratio to form a mixed raw material to be foamed, and the mixed raw material is then loaded into a storage device for later use. The storage device and the injection device are interconnected, and both the storage device and the injection device adopt existing technical structures, which are not specifically limited here.

[0042] Subsequently, the plate drive mechanism 5 drives the pressure plate 3 to move up or down to a preset height so that the mixed raw materials can form a sponge of a preset thickness during the foaming process, while keeping the top wall surface of the sponge relatively flat, thereby providing a stable geometric benchmark for subsequent rebound performance pre-testing.

[0043] Before foaming, padding paper is laid on the surface of the conveyor belt of the conveyor belt device 1. The padding paper material can be polyester fiber. The mixed raw materials in the storage device are quantitatively injected into the padding paper surface on the conveyor belt device 1 through the injection device, so that the mixed raw materials can freely foam on the padding paper and gradually form a sponge.

[0044] Once the sponge has completed foaming and reached the preset shape, the conveyor belt device 1 transports the sponge. During this process, the sponge is pre-inspected by the sponge pre-inspection mechanism.

[0045] Pre-detection working principle: When the conveyor belt device 1 conveys the sponge, the side wall of the sponge will push the movable permanent magnet strip 7, causing the movable permanent magnet strip 7 to be displaced along the guide direction of the damping slide rail 20. The displacement of the movable permanent magnet strip 7 drives the movable rack 8 to move synchronously. During the movement, the movable rack 8 causes the gear 13 meshing with it to rotate. The rotation of the gear 13 causes the convex post 14 on it to produce eccentric movement. The convex post 14 moves in the inner wall of the frame 15, thereby causing the frame 15 to move up and down.

[0046] Since the frame 15 is fixedly connected to the transmission cylinder 16, the lifting and lowering movement of the frame 15 further drives the transmission cylinder 16 to reciprocate up and down on the inner wall of the test cylinder 6. As the transmission cylinder 16 moves upward, the movable magnet 17 set inside the transmission cylinder 16 gradually approaches the permanent magnet plate 9. After the movable magnet 17 enters the magnetic field range of the permanent magnet plate 9, it is attracted by the permanent magnet plate 9 and moves upward rapidly. The movable magnet 17 moves away from the steel ball 19. After losing the magnetic force of the movable magnet 17, the steel ball 19 falls down onto the top wall of the sponge under its own gravity. The intelligent sensor system can detect the rebound height of the steel ball 19, thereby determining whether the rebound performance of the tested area of ​​the sponge meets the requirements. The intelligent sensor system may include at least one laser ranging sensor for real-time monitoring of the position of the steel ball 19. The intelligent sensor system and the processing module are electrically connected. The processing module may be built into other components of the device, such as the bracket 2, or it may be externally mounted on other devices. The processing module is used to analyze and process the data on the intelligent sensor system to determine the rebound height of the steel ball 19, thereby detecting the rebound performance of the sponge in the detected area.

[0047] Subsequently, the steel ball 19 eventually rests on the top surface of the sponge. Since the bottom wall of the test cylinder 6 is flush with the bottom wall of the pressure plate 3, the steel ball 19 will not leave the range of the test cylinder 6 under the joint envelopment of the sponge and the test cylinder 6.

[0048] As the transmission cylinder 16 moves downward, the inner wall of the groove on the transmission cylinder 16 causes the protrusion on the movable magnet 17 to move downward synchronously, thereby causing the movable magnet 17 to move downward as a whole. After the movable magnet 17 leaves the magnetic field of the permanent magnet plate 9, it falls under its own gravity and eventually comes into contact with the inner bottom wall of the transmission cylinder 16. Then, the bottom wall of the transmission cylinder 16 comes into contact with the steel ball 19, and the steel ball 19 is attracted again by the magnetic force of the movable magnet 17.

[0049] When the transmission cylinder 16 moves upward again, it drives the steel ball 19 upward as well, with the steel ball 19 always maintaining contact with the bottom wall of the transmission cylinder 16. This cycle is repeated, allowing the steel ball 19 to fall multiple times, thus pre-testing the resilience of different areas of the sponge's top wall.

[0050] Because the installation height and magnetic force range of the permanent magnet plate 9 are constant, the initial height of the steel ball 19 when it begins to fall freely is basically the same each time, thus ensuring the consistency of the rebound test conditions and improving the comparability and reliability of the test results.

[0051] When the movable permanent magnet strip 7 is pushed below the fixed magnet 10, it moves upward under the magnetic attraction of the fixed magnet 10, thus releasing it from contact with the sponge. At this time, the transmission line 11 is retracted into the automatic winding unit 12 under its automatic winding force. The transmission line 11 pulls the movable rack 8 to move in the opposite direction and reset to the position where it abuts against the automatic winding unit 12.

[0052] During the reset process, the damping effect of the second damping slide rail 20 slows down the falling speed of the movable permanent magnet strip 7, thus preventing it from falling rapidly and colliding with the side wall of the sponge, and avoiding the problem of the movable rack 8 failing to move smoothly in reverse. Simultaneously, due to the damping effect of the first damping slide rail 4, the reverse movement speed of the movable rack 8 is also slow, causing the gear 13 to rotate slowly in the reverse direction. This slow reverse rotation of the gear 13 also drives the periodic lifting and lowering motion of the transmission cylinder 16 and the movable magnet 17, causing the steel ball 19 to automatically drop multiple times at similar heights, thus pre-detecting the resilience performance of the sponge at different positions.

[0053] Finally, the sponge leaves the area below the pressure plate 3 under the conveyor belt device 1, completing the pre-detection and transmission process of the rebound performance.

[0054] The remaining sponge on the pressure plate 3 and side baffles can then be cleaned and recycled. The synthetic sponge is a type of plastic, and recycling it can reduce the environmental pollution caused by waste plastics.

[0055] Beneficial effects of this invention: This invention integrates a sponge pre-inspection mechanism into the conveyor belt device 1, enabling pre-inspection of the resilience performance of the foamed sponge without prior cutting or slicing. This solves the problems of cumbersome operation, long inspection cycle, and resource waste caused by the requirement to cut before inspection in existing technologies. Specifically, during the conveying process of the sponge, the linkage of components is triggered sequentially. Without additional electric drive components, the steel ball 19 falls freely to the top wall of the sponge multiple times at a preset height within the test cylinder 6, performing rebound impact tests on different areas of the sponge. This achieves rapid pre-inspection of resilience performance. Combined with the structure where the bottom wall of the test cylinder 6 is flush with the bottom wall of the pressure plate 3, the steel ball 19 is always confined within the test cylinder 6, preventing deviation or detachment and ensuring inspection reliability. Furthermore, the automatic rewinder 12 and the automatic reset function of the transmission line 11 allow the inspection process to be continuously cyclical without additional power intervention, thereby improving inspection efficiency and providing accurate screening basis for subsequent fine inspection. This significantly reduces the failure rate of subsequent fine inspection, reduces waste of manpower and resources, and lowers production costs.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit the scope of protection of the present invention. 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.
