[0019] This technical solution provides a foaming device for producing foamed products, used in a foaming tank. It includes a support frame, a lifting plate, a first rotating shaft, a first optical shaft, an annular sealing cap, a spring, a fixing ring, a first stirring blade, a first driving component, and a second driving component. The support frame rests against the ground, supporting the entire device. The lifting plate, along the height of the support frame, is located above it and supports the relevant components of the device. The first rotating shaft, along the height of the support frame, is rotatably mounted through the lifting plate and can rotate relative to it. The first optical shaft, along the height of the support frame, is slidably mounted through the lifting plate and can slide relative to it. The annular sealing cap is installed at the bottom end of the first optical shaft and fitted onto the first rotating shaft, sealing the opening of the foaming tank. The spring is fitted onto the first optical shaft and located between the annular sealing cap and the lifting plate, providing elasticity to give the sealing cap a tendency to move away from the lifting plate. The fixing ring is installed at the top end of the first optical shaft, acting as a limit to prevent the first optical shaft from detaching from the lifting plate. The first stirring blades are evenly installed on the first rotating shaft. Along the height direction of the support, multiple first stirring blades are located below the annular sealing cover for stirring the raw materials. A first driving component is installed between the support and the lifting plate to provide driving force, driving the lifting plate to move along the height direction of the support. A second driving component is installed between the lifting plate and the first rotating shaft to provide driving force, driving the first rotating shaft to rotate relative to the lifting plate. Under the drive of the first driving component, the multiple first stirring blades move into the interior of the foaming tank, and the annular sealing cover seals the opening of the foaming tank.

[0020] In use, after moving the foaming tank to the support, controlling the first drive component moves the lifting plate, which in turn moves the annular sealing plate and multiple first stirring blades until the stirring blades are inside the foaming tank. Under the guidance and support of the first optical shaft and the elasticity of the spring, the annular sealing cap tightly seals the opening of the foaming tank. Then, controlling the second drive component rotates the first rotating shaft, which in turn rotates the multiple first stirring blades to stir the raw materials. During stirring, as the multiple first stirring blades reciprocate up and down under the drive of the second drive component, the sealing plate still seals the opening of the foaming tank under the elasticity of the spring and the guidance and support of the first optical shaft, thus ensuring a tight seal while improving the stirring effect. Furthermore, the multiple first stirring blades can be moved out of the foaming tank by the second drive component, allowing for cleaning of the inside of the foaming tank and reducing time consumption.

[0038] Combination Figures 1 to 5As shown, this embodiment of the present disclosure provides a foaming device for producing foamed products, used in a foaming tank 1, including a support 2, a lifting plate 3, a first rotating shaft 4, a first optical shaft 5, an annular sealing cover 6, a spring 7, a fixing ring 8, a first stirring blade 9, a first driving component, and a second driving component. The support 2 is used to abut against the ground, thereby supporting the entire device. The lifting plate 3, along the height direction of the support 2, is located above the support 2 and is used to support and install related components of the device. The first rotating shaft 4, along the height direction of the support 2, is rotatably inserted through the lifting plate 3 and can rotate relative to the lifting plate 3. The first optical shaft 5, along the height direction of the support 2, is slidably inserted through the lifting plate 3 and can slide relative to the lifting plate 3. The annular sealing cover 6 is installed at the bottom end of the first optical shaft 5 and sleeved on the first rotating shaft 4, used to seal the opening of the foaming tank 1. The spring 7 is sleeved on the first optical shaft 5 and located between the annular sealing cover 6 and the lifting plate 3, used to provide elasticity so that the sealing cover has a tendency to move away from the lifting plate 3. A retaining ring 8 is installed at the top of the first optical axis 5 to limit its movement and prevent it from falling off the lifting plate 3. First stirring blades 9 are evenly installed on the first rotating shaft 4. Along the height direction of the bracket 2, multiple first stirring blades 9 are located below the annular sealing cover 6 for stirring the raw materials. A first driving component is installed between the bracket 2 and the lifting plate 3 to provide driving force, causing the lifting plate 3 to move along the height direction of the bracket 2. A second driving component is installed between the lifting plate 3 and the first rotating shaft 4 to provide driving force, causing the first rotating shaft 4 to rotate relative to the lifting plate 3. Under the drive of the first driving component, multiple first stirring blades 9 move into the interior of the foaming tank 1, and the annular sealing cover 6 seals the opening of the foaming tank 1.

[0039] This embodiment of the invention provides a foaming device for producing foamed products. After moving the foaming tank 1 to the support 2, controlling the first driving component moves the lifting plate 3, which in turn moves the annular sealing plate and multiple first stirring blades 9. This continues until the multiple first stirring blades 9 are inside the foaming tank 1. Under the guiding support of the first optical axis 5 and the elastic force of the spring 7, the annular sealing cover 6 tightly seals the opening of the foaming tank 1. Then, controlling the second driving component rotates the first rotating shaft 4, which in turn rotates the multiple first stirring blades 9 to stir the raw materials. During the stirring process, as the multiple first stirring blades 9 reciprocate up and down under the drive of the second driving component, the sealing plate still seals the opening of the foaming tank 1 under the elastic force of the spring 7 and the guiding support of the first optical axis 5, thus improving the stirring effect while ensuring a tight seal. Furthermore, the multiple first stirring blades 9 can be moved out of the foaming tank 1 by the second driving component, allowing for cleaning of the interior of the foaming tank 1 and reducing time consumption.

[0040] Optionally, combined Figure 1 , Figure 2 and Figure 5 As shown, the first driving component includes a first motor 10, a driving pulley 11, a driven pulley 12, and a belt 13. The first motor 10 is mounted on the bottom surface of the lifting plate 3, and its rotating end passes through the lifting plate 3 to provide driving force for rotational motion. The driving pulley 11 is mounted on the rotating end of the first motor 10 and rotates under the drive of the first motor 10. The driven pulley 12 is mounted on the top of the first rotating shaft 4 to drive the first rotating shaft 4 to rotate. The belt 13 is fitted between the driving pulley 11 and the driven pulley 12 to transmit driving force.

[0041] In this embodiment, controlling the first motor 10 to operate drives the drive pulley 11 to rotate. This, in turn, drives the driven pulley 12 to rotate via the belt 13. This, in turn, drives the first rotating shaft 4 to rotate, ultimately achieving the function of automatic rotation of the multiple first stirring blades 9.

[0042] Optionally, combined Figure 1 , Figure 2 and Figure 5 As shown, the first drive component also includes a protective cover 14.

The sprockets 17 are mounted on the two second rotating shafts 16 and support the chain 18. The chain 18 is fitted onto the two sprockets 17 and rotates continuously along a specific trajectory on the bracket 2 of the two sprockets 17. The lifting seat 19 is mounted on the chain 18, located between the two sprockets 17 along the height direction of the bracket 2, and moves under the drive of the chain 18. The second optical axis 20 is slidably installed along the height direction of the support 2. The bottom end of the second optical axis 20 is connected to the lifting seat 19, and the top end of the second optical axis 20 is connected to the lifting plate 3. The second optical axis 20 serves as a guide and support, and causes the lifting plate 3 to move as the lifting seat 19 moves. The second rotating shaft 16 on either side can be controlled to rotate, thereby moving the lifting plate 3 along the height direction of the support 2.

[0045] In this embodiment, when the second rotating shaft 16 on either side is driven to rotate by an external force, it can drive the sprocket 17 on it to rotate. With the support of the second sprocket 17 on the other side, the chain 18 can rotate continuously along a specific trajectory. Then, under the guiding support of the second optical shaft 20, the lifting plate 3 can move along with the lifting seat 19 to realize the lifting function.
