[0039] Please see Figure 1-4 As shown, this embodiment is a polyurethane foam blowing machine, comprising:

[0040] Main components: The main components include a collection cylinder 11 and a stirring tank 12;

[0041] The mixing tank 12 is fixedly connected to the top of the collecting cylinder 11;

[0042] The main components also include a guide pipe 13, a housing 14, and a discharge pipe 15.

[0043] The feed pipe 13 is fixedly connected to one side of the outer wall of the mixing tank 12, the box body 14 is fixedly connected to one end of the feed pipe 13, and the discharge pipe 15 is installed on the top of the box body 14.

[0045] The above parts are existing technical solutions;

[0046] The stirring assembly includes a motor 21, a turntable 22, and an auxiliary rod 23;

[0047] The motor 21 is installed at the top of the mixing tank 12, the turntable 22 is rotatably connected to the inner top wall of the mixing tank 12, and the auxiliary rod 23 is fixedly connected to the bottom of the turntable 22.

[0048] The mixing assembly also includes a rotating gear 24, a stirring rod 25, a limiting frame 26, and a mixing tank 27;

[0049] The stirring rod 25 is installed at one end of the auxiliary rod 23, the rotating gear 24 is fixedly connected to one end of the stirring rod 25, the turntable 22 and the rotating gear 24 are meshed, the mixing tank 27 is fixedly connected to the center of the mixing tank 12, and the limiting frame 26 is installed inside the mixing tank 12.

[0050] The output shaft of motor 21 is fixedly connected to turntable 22 via a coupling. Turntable 22 and rotating gear 24 are set on the same central axis. Auxiliary rod 23 is used to provide rotational guide trajectory for rotating gear 24. Limiting frame 26 is used to provide space for the auxiliary rod 23 to move. Mixing bucket 27 is used to provide space for stirring foam raw materials.

[0051] Through the meshing between the turntable 22 and the rotating gear 24, the turntable 22 can drive the rotating gear 24 to rotate during its rotation, thereby allowing the stirring rod 25 to stir inside the mixing tank 27 under the guidance of the auxiliary rod 23.

[0052] Working principle: When the worker foams the foam material;

[0053] First, by starting the motor 21, the output shaft of the motor 21 can drive the turntable 22 to rotate through the coupling. As the turntable 22 rotates, it drives the rotating gear 24 meshing with one side to rotate, thereby causing the stirring rod 25, which is fixedly connected to one end of the rotating gear 24, to rotate.

[0054] Next, a stirring rod 25 is sleeved on one end of the auxiliary rod 23, and the stirring rod 25 passes through the inside of the limiting frame 26, so that the stirring rod 25 can be uniformly stirred inside the mixing tank 27.

[0055] This step can improve the mixing effect of foam and enhance the quality of foam foaming.

[0056] Please see Figure 1-4 As shown, this embodiment is based on embodiment 1 above, and further includes a feeding component;

[0057] The feeding assembly includes a hydraulic rod 31, a sliding plate 32, and a material storage tube 33;

[0058] The hydraulic rod 31 is installed on the rear side of the housing 14, the slide plate 32 is installed on one end of the hydraulic rod 31, and the storage pipe 33 is fixedly connected to the center of the bottom end of the slide plate 32.

[0062] With the auxiliary cooperation between the hydraulic rod 31 and the slide plate 32, the slide plate 32 can slide repeatedly inside the slide frame 36, so that the foam raw material in the feed pipe 15 can be quantitatively fed through the storage pipe 33.

[0063] Working principle: When the worker feeds the foam raw material;

[0064] First, by pouring the foam material into the inside of the feeding pipe 15, the hydraulic rod 31 is activated. During the operation of the hydraulic rod 31, the slide plate 32, which is fixedly connected at one end, is driven to slide repeatedly inside the slide frame 36. As the slide plate 32 slides, the foam material inside the feeding pipe 15 falls and is collected into the inside of the storage pipe 33.

[0065] Next, when the storage tube 33 slides out and is released from the mounting bracket 35, the movable cover 34 connected to the bottom of the storage tube 33 can be flipped down, so that the foam material in the storage tube 33 can be discharged through the discharge chute.

[0066] This step helps staff to quantitatively feed foam raw materials, thereby improving the quality of foam foaming.
