A cover plate assembly is installed on the rotating component and below the multiple stirring paddles. A crushing and processing device is installed on the support plate and on one side of the rotating component. A movable heating device is installed at the bottom of the box body.
[0004] In the aforementioned patent, by setting up a crushing and processing device, the foaming box can crush and process the raw materials to a certain extent when needed through the cooperation of crushing blades and motors, thereby better meeting the working needs under different circumstances and improving the working capacity of the foaming box. However, by using the synergistic effect of the rotating component and the stirring paddle to stir and mix the raw materials, material residue may appear on the inner wall of the foaming box during the stirring process. In addition, multiple stirring paddles continuously rotate in the same direction, resulting in low stirring and mixing efficiency.
[0005] Therefore, this utility model provides a sponge foaming box for a sponge production line to solve the above problems. Utility Model Content

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] This utility model provides a sponge foaming box for a sponge production line, such as... Figure 1 , Figure 2 and Figure 4 As shown, the foam box includes a movable base plate 1, a foam box body 2 fixedly installed on the top of the movable base plate 1, a top plate 3 disposed above the foam box body 2, and a scraping mechanism disposed on the top plate 3 for scraping the inner wall of the foam box body 2.
[0032] The scraping mechanism includes a first motor 4 fixedly mounted on the top of the top plate 3, a rotating shaft 5 fixedly mounted on the output end of the first motor 4, a first gear 6 fixedly mounted on the side surface of the rotating shaft 5, a second gear 7 rotatably mounted on the bottom of the top plate 3, an internal gear ring 8 rotatably mounted on the bottom of the top plate 3, a rotating frame 9 fixedly mounted on the bottom of the internal gear ring 8, an agitator 10 fixedly mounted on the rotating shaft 5 and the rotating frame 9, and a scraper 11 fixedly mounted on the side surface of the rotating frame 9.
[0033] Multiple second gears 7 are provided, and the second gears 7 are arranged in a ring array at the bottom of the top plate 3. The first gear 6 meshes with multiple second gears 7, and the multiple second gears 7 mesh with the internal gear ring 8.
[0034] Multiple stirring paddles 10 are provided, and the stirring paddles 10 are evenly distributed on the rotating shaft 5 and the rotating frame 9. The side of the scraper 11 away from the rotating frame 9 is in contact with the inner wall of the foaming box body 2.
[0035] When using this foaming box, the casters on the bottom of the base plate 1 are moved to a suitable position. Then, the first motor 4 is started. The output of the first motor 4 drives the rotating shaft 5 to rotate, and the rotating shaft 5 drives the first gear 6 to rotate. Since the first gear 6 meshes with multiple second gears 7, and the multiple second gears 7 mesh with the internal gear ring 8, when the first gear 6 rotates, it will drive the second gears 7 and the internal gear ring 8 to rotate synchronously. The internal gear ring 8 drives the rotating frame 9 to rotate. The rotating frame 9 and the stirring paddle 10 on the rotating shaft 5 stir the raw materials in the foaming box body 2. At the same time, the scrapers on the side surface of the rotating frame 9... 11. The inner wall of the foaming box body 2 is scraped to prevent raw materials from adhering to the inner wall of the foaming box body 2 and affecting the foaming effect of the sponge. In addition, by setting multiple second gears 7 and internal gear rings 8, the stirring paddle 10 and scraper 11 can achieve all-round stirring and scraping. Furthermore, the rotating frame 9 and the rotating shaft 5 rotate in opposite directions, so the stirring paddle 10 on the rotating frame 9 and the stirring paddle 10 on the rotating shaft 5 stir in opposite directions, thus improving the efficiency of stirring and scraping and ensuring the foaming quality of the sponge. At the same time, the structure of this sponge foaming box is simple, easy to operate, easy to maintain and clean, and suitable for use in various sponge production lines.
[0036] Furthermore, to facilitate temperature control inside the foaming chamber body 2, such as... Figure 1 , Figure 2 and Figure 5 As shown, a placement groove 12 is provided at the bottom of the foaming box body 2, and an electric heating wire 13 is fixedly connected inside the placement groove 12.
[0037] A heat-conducting aluminum ring 14 is fixedly connected inside the mounting groove 12, and the heat-conducting aluminum ring 14 passes through the mounting groove 12.
[0038] When in use, the foaming box heats the inside of the body 2 of the foaming box through the electric heating wire 13, thereby increasing the temperature of the raw materials and accelerating the foaming speed, thus improving the production efficiency of the sponge. The setting of the heat-conducting aluminum ring 14 allows the heat to be evenly and quickly transferred to all parts of the foaming box body 2, ensuring the uniformity of sponge foaming. At the same time, the combined use of the electric heating wire 13 and the heat-conducting aluminum ring 14 allows the heating temperature to be adjusted according to actual needs to meet the production requirements of different sponge products.
[0039] In order to facilitate the control of the lifting and lowering of the top plate 3, such as Figure 1 , Figure 2 and Figure 3 As shown, an electric push rod 15 is fixedly connected to the top of the movable base plate 1, a telescopic rod 16 is fixedly connected to the top of the movable base plate 1, and a protrusion 17 is fixedly connected to the side surface of the top plate 3.
[0040] Multiple protrusions 17 are provided, and the movable ends of the electric push rod 15 and the telescopic rod 16 are respectively fixedly connected to the bottom of multiple protrusions 17.
[0041] When in use, the foaming box utilizes the coordinated action of the electric push rod 15 and the telescopic rod 16 to achieve smooth lifting and lowering of the top plate 3. The electric push rod 15 provides the main lifting power, ensuring that the top plate 3 can quickly and accurately reach the predetermined position, while the telescopic rod 16 provides auxiliary support and stability, effectively preventing the top plate 3 from swaying or shifting during lifting and lowering. The protrusion 17 ensures that the electric push rod 15 and the telescopic rod 16 can be firmly connected to the top plate 3, guaranteeing the reliability and stability of the lifting action. By adjusting the telescopic length of the electric push rod 15, the height of the top plate 3 can be easily controlled, thereby adapting to the production needs of different foam products and improving the flexibility and applicability of the equipment.
[0042] Furthermore, to facilitate the crushing of raw materials, such as... Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, a feed pipe 18 is fixedly connected to the top of the top plate 3, a cover plate 19 is provided on the top of the feed pipe 18, and a filter plate 20 is fixedly connected inside the feed pipe 18.
[0043] A second motor 21 is fixedly connected to one side of the feed pipe 18, and a rotating rod 22 is rotatably connected inside the feed pipe 18.
[0044] The movable end of the second motor 21 passes through one side of the feed pipe 18 and is fixedly connected to one end of the rotating rod 22. A spiral cutter 23 is fixedly connected to the side surface of the rotating rod 22.
[0045] When using this foaming box, the operator can first pour the raw materials into the foaming box body 2 through the feed pipe 18. At this time, the cover plate 19 can prevent the raw materials from splashing out during the pouring process, ensuring a clean operating environment. The filter plate 20 can perform preliminary screening of the raw materials, removing large particles and impurities, ensuring the quality of the raw materials entering the foaming box. After the raw materials enter the feed pipe 18, the operator can start the second motor 21. The second motor 21 drives the rotating rod 22 to rotate, which in turn drives the spiral cutter 23 to crush the raw materials. The rotation of the spiral cutter 23 can effectively cut the raw materials into finer particles, improving the uniformity of the raw materials and the foaming effect. The crushed raw materials then enter the foaming box body 2, where they are mixed with other components for foaming treatment. Through this series of designs, the foaming box not only improves the utilization rate of raw materials and the foaming quality, but also greatly simplifies the operation process and reduces the difficulty of operation.
[0046] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
