They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0028] The present invention will be further described below with reference to the accompanying drawings:

A connecting rod 603 is slidably connected to the front side of the clamping bracket 601, a spring 606 is fixedly connected to the rear end of the connecting rod 603, and the rear end of the spring 606 is fixedly connected to the clamping bracket 601. Symmetrically arranged arc-shaped guide grooves are provided at the front end of the clamping bracket 601, and an upper clamping block 602 is slidably connected to the upper arc-shaped guide groove of the clamping bracket 601. A lower clamping block 604 is connected, with a boss fixedly connected to its front end. An upper clamping block 602 and the rear ends of the lower clamping block 604 are rotatably connected to a connecting rod 603. A limit plate 605 is rotatably connected to the front end of the upper clamping block 602. The other end of the limit plate 605 is provided with a groove that mates with the boss at the front end of the lower clamping block 604. When the operator places the stirring shaft into the clamping mechanism, the stirring shaft presses the connecting rod 603 inward. At this time, the spring 606 is compressed, and the inward movement of the connecting rod 603 causes the upper clamping block 602 and the lower clamping block 604 to move towards each other, thus clamping the stirring shaft. Rotating the limit plate 605 causes the groove on the limit plate 605 to engage with the boss at the front end of the lower clamping block 604, preventing the clamping mechanism from separating. To disassemble the stirring shaft, simply reverse the operation.

[0030] The foaming mechanism includes a foaming box 101, with a foaming observation window 102 on the front side. A first motor 103 is fixedly connected to the upper part of the foaming box 101, and a foaming discharge pipe 109 is fixedly connected to the lower part of the foaming box 101. A drive gear 104 is fixedly connected to the output end of the first motor 103, and the drive gear 104 is rotatably connected to the foaming box 101. The drive gear 104 meshes with symmetrically arranged driven gears 105, which are rotatably connected to the foaming box 101. A foaming rotating shaft 106 is fixedly connected to the lower part of the driven gear 105, and is rotatably connected to the foaming box 101. A number of evenly arranged foaming paddle supports 107 are fixedly connected to the foaming paddle supports 107.

When the first motor 103 is started, the output end of the first motor 103 rotates, driving the drive gear 104 to rotate. The drive gear 104 rotates, driving the driven gear 105 to rotate. The driven gear 105 rotates, driving the foaming rotating shaft 106 to rotate. The rotation of the foaming rotating shaft 106 drives the foaming paddle supports 107 and the foaming net paddles 108 on them to rotate. The double foaming shaft of the foaming mechanism can accelerate the foaming speed, and the foaming net paddles 108 can make the bubbles inside the foaming agent uniform and fine.

[0031] The initial mixing mechanism includes an inlet pipe 201 fixedly connected to the top of the foaming tank 101, and a mixing pump body 202 fixedly connected to the other end of the inlet pipe 201.

The water pump 206 starts to pump the foaming agent inside the water storage tank 207 into the primary mixing tank 203. The mixing and stirring roller set inside the primary mixing tank 203 starts to mix the water and the foaming agent. The mixing pump 202 starts to pump the mixed foaming agent into the foaming mechanism through the liquid inlet pipe 201. Through the setting of the primary mixing mechanism, the foaming agent and water can be initially mixed. After the mixed foaming agent is sent into the foaming mechanism, it helps to make the foaming more uniform.

[0032] The air supply mechanism includes an air inlet pipe 301 fixedly connected to the foaming box 101. A heating box 302 is fixedly connected to the lower end of the air inlet pipe 301. Several heating wires are installed inside the heating box 302. An air compressor 303 is fixedly connected to the lower end of the heating box 302 through a pipe. When the air compressor 303 is started, it draws outside air into the air supply mechanism to form high-pressure gas. When the high-pressure gas passes through the heating box 302, the heating wires inside the heating box 302 heat the high-pressure gas. Then, the high-pressure gas is introduced into the foaming mechanism through the air inlet pipe 301. The introduction of high-pressure hot air helps the foaming of the foaming agent.

[0033] The mixing tank includes a mixing shell 402. A foaming feed pipe 401 is fixedly connected to the rear side of the mixing shell 402. The foaming feed pipe 401 and the foaming discharge pipe 109 are fixedly connected by a pipe. A gypsum feed pipe 403 is fixedly connected to the left side of the mixing shell 402. A slurry discharge pipe 406 is fixedly connected to the right side of the mixing shell 402. A second motor 405 is fixedly connected to one side of the mixing shell 402. A coupling 407 is fixedly connected to the output end of the second motor 405. 07 The other end is provided with an internal hexagon. The front side of the mixing shell 402 is rotatably connected to the cover 404. The cover 404 is provided with a mixing observation window 408. The foaming agent after foaming is introduced into the mixing shell 402 through the foaming feed pipe 401. The gypsum will enter the mixing shell 402 through the gypsum feed pipe 403. The second motor 405 rotates and drives the mixing shaft to rotate, so as to fully mix the foaming agent and the gypsum slurry. The mixed gypsum slurry leaves the foaming machine through the slurry discharge pipe 406.

[0034] The stirring shaft includes a stirring drive shaft 503 clamped on a clamping mechanism. Several axially uniformly arranged stirring paddle supports 502 are fixedly connected to the stirring drive shaft 503. Several circumferentially uniformly arranged stirring blades 501 are bolted to the stirring paddle supports 502. One end of the stirring drive shaft 503 is a hexagonal prism, and a coupling 407 is fitted to the other end of the stirring drive shaft 503. The bolted connection between the stirring paddle supports 502 and the stirring blades 501 allows the stirring blades 501 to be replaced without removing the stirring shaft. This design also increases the service life of the stirring shaft.

[0035] Working principle: The foaming agent pump 204 starts, pumping the foaming agent from the foaming agent storage tank 205 into the primary mixing tank 203. The water pump 206 starts, pumping the foaming agent from the water storage tank 207 into the primary mixing tank 203. The mixing roller inside the primary mixing tank 203 starts, mixing the water and foaming agent. The mixing pump 202 starts, pumping the mixed foaming agent through the inlet pipe 201 into the foaming mechanism. The air compressor 303 starts, drawing in external air into the air supply mechanism to form high-pressure gas. When the high-pressure gas passes through the heating box 302, the heating wire inside the heating box 302 heats the high-pressure gas, which then flows into the foaming mechanism through the air inlet pipe 301. The first motor 103 starts, and the output of the first motor 103 rotates, driving the drive gear 104 to rotate. The rotation of the drive gear 104 drives the... The driven gear 105 rotates, which in turn drives the foaming rotating shaft 106 to rotate. The rotation of the foaming rotating shaft 106 drives the rotation of the foaming paddle support 107 and the foaming net paddle 108 on it, causing the foaming agent to foam. The foamed foaming agent is then fed into the mixing shell 402 through the foaming feed pipe 401. The gypsum is fed into the mixing shell 402 through the gypsum feed pipe 403. The second motor 405 rotates, driving the mixing shaft to rotate, which fully mixes the foaming agent and the gypsum slurry. The mixed gypsum slurry leaves the foaming machine through the slurry discharge pipe 406. When the mixing shaft needs to be replaced, the box cover 404 is opened to release the limit plate 605. At this time, the spring 606 resets, driving the other parts to reset as well. The operator can then remove the mixing shaft for replacement. Installation is done by reversing the operation.
