[0020] The present utility model provides a foaming device, which includes a mixing tank 101, two mixing mechanisms, a feed pipe 102, a first solenoid valve 103, a discharge pipe 104, a second solenoid valve 105, a transparent glass plate 106, and a plurality of support legs 107. Each of the mixing mechanisms includes a plurality of connecting rods 108, a fixing plate 109, a motor 110, a driving gear 111, a plurality of driven gears 112, a plurality of rotating shafts 113, and a plurality of rotating blades 114.
[0021] For this specific embodiment, the two mixing mechanisms are respectively located at the upper and lower ends of the mixing tank 101. When mixing and foaming are required, the output end of the motor 110 in the upper mixing mechanism drives the driving gear 111 to rotate forward, thereby driving a plurality of driven gears 112, a plurality of rotating shafts 113, and a plurality of rotating blades 114 to rotate forward, and the motor 110 in the lower mixing mechanism rotates in the reverse direction, thereby driving a plurality of rotating blades 114 below to rotate in the reverse direction. Thus, through different rotations, the raw materials and foaming agent in the mixing tank 101 are fully mixed. Therefore, the device can uniformly and fully mix the raw materials and foaming agent, so that the foaming effect is better. Before mixing and foaming, the first solenoid valve 103 is opened, and the raw materials and foaming agent are poured into the mixing tank 101 through the feed pipe 102. After the raw materials and foaming agent are foamed, the second solenoid valve 105 is opened to discharge them from the discharge pipe 104. Through the setting of the transparent glass plate 106, the staff can easily observe the mixing and foaming conditions of the raw materials and foaming agent in the mixing tank 101. Through the setting of the plurality of support legs 107, the device is supported and carried.
[0022] One end of each of the multiple connecting rods 108 is fixedly connected to the mixing tank 101 respectively, and the other end of each of the multiple connecting rods 108 is fixedly connected to the fixing plate 109 respectively. The driving gear 111 is rotatably connected to the fixing plate 109 and is located on the side of the fixing plate 109 close to the mixing tank 101. Each of the multiple driven gears 112 is rotatably connected to the fixing plate 109, and each of the multiple driven gears 112 is in meshing engagement with the driving gear 111. The motor 110 is fixedly connected to the fixing plate 109. The output end of the motor 110 penetrates through the fixing plate 109 and is fixedly connected to the driving gear 111. One end of each of the multiple rotating shafts 113 is fixedly connected to the corresponding driven gear 112 respectively, and the other end of each of the multiple rotating shafts 113 penetrates through the outer wall of the mixing tank 101. Each of the multiple rotating blades 114 is arranged on the corresponding rotating shaft 113 and is located inside the mixing tank 101 respectively. The two mixing mechanisms are respectively located at the upper end and the lower end of the mixing tank 101. When mixing and foaming are required, the output end of the motor 110 in the upper mixing mechanism drives the driving gear 111 to rotate forward, thereby driving each of the multiple driven gears 112, each of the multiple rotating shafts 113 and each of the multiple rotating blades 114 to rotate forward, and the motor 110 in the lower mixing mechanism rotates reversely, thereby driving each of the multiple rotating blades 114 in the lower part to rotate reversely, so as to fully mix the raw materials and the foaming agent in the mixing tank 101 through different rotations. Thus, the device can uniformly and fully mix the raw materials and the foaming agent, so that the foaming effect is better.
[0023] Secondly, the feed pipe 102 is communicated with the left end of the mixing tank 101. The first solenoid valve 103 is arranged on the feed pipe 102. The discharge pipe 104 is communicated with the right end of the mixing tank 101. The second solenoid valve 105 is arranged on the discharge pipe 104. Before mixing and foaming, the first solenoid valve 103 is opened, and the raw materials and the foaming agent are poured into the mixing tank 101 through the feed pipe 102. After the raw materials and the foaming agent are foamed, the second solenoid valve 105 is opened to discharge them from the discharge pipe 104.
[0024] Meanwhile, the transparent glass plate 106 is arranged on the mixing tank 101. Through the arrangement of the transparent glass plate 106, the staff can easily observe the mixing situation and the foaming situation of the raw materials and the foaming agent in the mixing tank 101.
[0025] In addition, each of the multiple support legs 107 is fixedly connected to the mixing tank 101 respectively and is located around the bottom of the mixing tank 101 respectively. Through the arrangement of the multiple support legs 107, the device is supported and carried.
[0026] When using the foaming device of the present utility model, the two mixing mechanisms are respectively located at the upper and lower ends of the mixing tank 101. When mixing and foaming are required, the output end of the motor 110 in the upper mixing mechanism drives the driving gear 111 to rotate forward, thereby driving multiple driven gears 112, multiple rotating shafts 113, and multiple rotating blades 114 to rotate forward. And the motor 110 in the lower mixing mechanism rotates reversely, thereby driving the multiple rotating blades 114 below to rotate reversely. Thus, through different rotations, the raw materials and foaming agent in the mixing tank 101 are fully mixed. Therefore, the device can mix the raw materials and foaming agent evenly and fully, so that the foaming effect is better. Before mixing and foaming, open the first solenoid valve 103, and pour the raw materials and foaming agent into the mixing tank 101 through the feed pipe 102. When the raw materials and foaming agent are foamed, open the second solenoid valve 105 to discharge them from the discharge pipe 104. The staff can, through the setting of the transparent glass plate 106, easily observe the mixing and foaming conditions of the raw materials and foaming agent in the mixing tank 101. Through the setting of multiple support legs 107, the device is carried and supported.

[0030] For this specific embodiment, when the driving gear 111 rotates, it drives the main shaft 201 to rotate, and then drives multiple stirring rods 202 to rotate, thereby mixing the raw materials and foaming agent. Through the above setting, the mixing effect of the device on the raw materials and foaming agent can be further improved.
[0031] One end of the main shaft 201 is fixedly connected to the driving gear 111. The other end of the main shaft 201 penetrates through the outer wall of the mixing tank 101. A plurality of stirring rods 202 are respectively arranged around the main shaft 201 and are respectively located inside the mixing tank 101. When the driving gear 111 rotates, it drives the main shaft 201 to rotate, and further drives the plurality of stirring rods 202 to rotate, thereby mixing the raw materials and the foaming agent. Through the above arrangement, the mixing effect of the device on the raw materials and the foaming agent can be further improved.
