[0023] The foaming bin 1 is used to foam the raw materials. A feed port with a sealing mechanism is provided on the top of the foaming bin 1 to ensure the sealing of the device during use. The stirring shaft 3 can stir the raw materials inside the foaming bin 1 so that the raw materials can be evenly mixed with air, ensuring the foaming effect of the device. The motor 6 provides power for the rotation of the stirring shaft 3. The stirring shaft 3 is rotated by the motor 6 under the action of the meshing gears 61. The mounting frame 5 is used to install the stirring shaft 3. During the rotation of the stirring shaft 3, the isolation bin 11, the foaming bin 1 and the mounting frame 5 all support the stirring shaft 3. The role of the stirring shaft 3 is to ensure the stability of the stirring shaft 3 during the rotation process. The air inlet pipe 2 can introduce external steam into the stirring shaft 3. The steam entering the stirring shaft 3 will be sprayed onto the raw materials through the exhaust hole 4, thereby realizing the heating of the raw materials. The exhaust hole 4 is arranged on the blade of the stirring shaft 3. In the process of the stirring shaft 3 stirring the raw materials, the steam can evenly contact all the raw materials through the exhaust hole 4, ensuring that the raw materials can be evenly heated and the working effect of the device is ensured. The filter 41 can prevent the raw materials from entering the interior of the stirring shaft 3 through the exhaust hole 4, resulting in the working efficiency of the device. The effect is affected, and the intermittent sealing between the air inlet pipe 2 and the stirring shaft 3 can be achieved through the cooperation of the sealing plate 7 arranged on the air inlet pipe 2 and the stirring shaft 3, so that the steam can be intermittently sent into the foaming chamber 1 at a certain frequency, so as to avoid a large amount of steam entering the foaming chamber 1 at one time and affecting the working effect of the device. The installation ring 71 arranged on the sealing plate 7 and the groove matched with the installation ring 71 ensure the stability of the cooperation between the sealing plates 7 and the working effect of the sealing plate 7. The cooperation between the installation ring 71 and the groove matched with the installation ring 71 also improves the connection between the air inlet pipe 2 and the stirring shaft 3. Stability, the sealing plate 12 can clamp the discharge of the foaming bin 1 to ensure the sealing of the foaming bin 1, the top surface of the sealing plate 12 is flush with the bottom surface of the inner wall of the foaming bin 1, to prevent the raw materials from entering the discharge port of the foaming bin 1, resulting in some raw materials being unable to be stirred by the stirring shaft 3, thereby affecting the working effect of the device, the sealing plate 12 is slidably installed on the discharge port of the foaming bin 1, and the area of ​​the channel connecting the discharge port of the foaming bin 1 and the interior of the foaming bin 1 can be controlled by adjusting the position of the sealing plate 12, thereby realizing the adjustment of the speed at which the device discharges foam, which is convenient for users to collect materials.

[0025] The shape of the bottom of the inner wall of the foaming bin 1 ensures that all the foam inside the foaming bin 1 can be discharged through the discharge port of the foaming bin 1. The shape of the bottom of the inner wall of the foaming bin 1 and the cooperation of the bottom blades of the stirring shaft 3 ensure that the stirring shaft 3 can stir the raw materials at the bottom, thereby ensuring the working effect of the stirring shaft 3.

[0026] Specifically, the top surface of the blade of the stirring shaft 3 is in the shape of an inclined surface inclined from the center to both sides, and each side wall of the blade of the stirring shaft 3 is provided with an exhaust hole 4 .

The shape of the blades of the stirring shaft 3 can also prevent the steam ejected from adjacent blades from interfering with each other. The top surface shape of the blades of the stirring shaft 3 ensures that the steam ejected from the exhaust hole 4 located above is ejected obliquely upward, thereby expanding the contact area between the steam and the raw materials and ensuring the heating effect of the steam. The position of the exhaust hole 4 ensures that the steam can contact the raw materials evenly and ensures the working effect of the device.

[0028] Specifically, the top surface of the support rod of the mounting frame 5 is in the shape of an inclined plane inclined from the center to both sides, and the shape of the portion of the mounting frame 5 where the stirring shaft 3 is mounted is a truncated cone.

[0029] The shape of the support rod of the mounting frame 5 and the part of the mounting frame 5 on which the stirring shaft 3 is mounted can prevent the raw materials from piling up on the mounting frame 5, ensuring that all the foamed raw materials in the foaming chamber 1 can be discharged through the discharge port of the foaming chamber 1. The shape of the part of the mounting frame 5 on which the stirring shaft 3 is mounted increases the contact area between the mounting frame 5 and the stirring shaft 3, thereby improving the stability of the stirring shaft 3 during rotation.

[0030] Specifically, the portion of the stirring shaft 3 connected to the air inlet pipe 2 is located inside the side wall of the isolation chamber 11, and a limiting ring 31 is provided on the portion of the stirring shaft 3 located inside the side wall of the isolation chamber 11 and inside the mounting frame 5. The isolation chamber 11 and the mounting frame 5 are provided with grooves that cooperate with the limiting ring 31.

[0031] The position of the connection between the air inlet pipe 2 and the stirring shaft 3 ensures the stability of the stirring shaft 3 during the rotation process.

[0033] The rubber pad 13 seals the gap between the intake pipe 2 and the groove of the isolation chamber 11, thereby preventing the intake pipe 2 from colliding with the isolation chamber 11 during the rotation of the stirring shaft 3, ensuring the stability of the intake pipe 2 during the use of the device and extending the service life of the intake pipe 2. The position of the rubber pad 13 also prevents the stirring shaft 3 from damaging the rubber pad 13 during rotation, thereby extending the service life of the rubber pad 13.

[0034] Specifically, a heat insulating layer 14 is provided inside the foaming bin 1, a protrusion is provided on the side wall of the sealing plate 12, a groove matching the sealing plate 12 is provided on the side wall of the discharge port of the foaming bin 1, and a sealing gasket is provided on the side wall of the sealing plate 12 and the groove for installing the sealing plate 12.

[0035] The heat-insulating layer 14 ensures the heat preservation effect of the foaming chamber 1 and improves the working effect of the device. The stability of the sealing plate 12 during movement is ensured by the cooperation of the side wall protrusion of the sealing plate 12 and the side wall groove of the discharge port. The sealing layer arranged on the sealing plate 12 and the groove for installing the sealing plate 12 can prevent steam from leaking out through the gap between the sealing plate 12 and the discharge groove.

[0036] The working principle and use process of the utility model are as follows: raw materials are added into the interior of the foaming bin 1 through the top feed port of the foaming bin 1, steam is introduced into the interior of the stirring shaft 3 through the air inlet pipe 2, the steam entering the interior of the stirring shaft 3 is sprayed onto the raw materials through the exhaust hole 4, the motor 6 is started, and the power of the motor 6 is transmitted to the stirring shaft 3 through the cooperation of the meshing gears 61, the stirring shaft 3 starts to rotate, and as the stirring shaft 3 rotates, the raw materials are stirred, thereby achieving uniform heating of the raw materials, and as the stirring shaft 3 rotates, the relative positions of the sealing plates 7 on the air inlet pipe 2 and the stirring shaft 3 change, and the sealing plates 7 are used to close the connection between the air inlet pipe 2 and the stirring shaft 3 through the cooperation of the two sealing plates 7, thereby achieving quantitative intermittent input of steam and ensuring the working effect of the device, and after the foaming of the raw materials is completed, the sealing plate 12 is pulled out, and the foamed raw materials leave the foaming bin 1 through the bottom discharge port.
