For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0026] In one embodiment of the present invention, Figure 1 - Figure 4 As shown, a high-pressure foaming machine with a quantitative feeding function is provided, including a storage bin 1, a feeding plate 2 is arranged on the top of the storage bin 1, a feeding pipe 3 is fixedly connected to the bottom of the storage bin 1, one end of the feeding pipe 3 is fixedly connected to a quantitative bin 4, a workbench 21 is fixedly connected to the lower surface of the storage bin 1, an electric push rod 7 is fixedly connected to the upper surface of the workbench 21, an output end of the electric push rod 7 is fixedly connected to a push plate 6, an outer wall of the push plate 6 is slidably connected to the upper surface of the workbench 21, and a piston rod 5 is fixedly connected to the outer wall of the push plate 6 One end of the piston rod 5 is slidably connected to the inside of the quantitative bin 4, and the inside of the quantitative bin 4 is rotatably connected to a rotating shaft 10, one end of the rotating shaft 10 is fixedly connected to a three-way cylinder 11, and the three-way cylinder 11 is rotatably connected to the inner wall of the quantitative bin 4. A linkage component is provided inside the advancement plate 6, and the linkage component is used to control the rotation of the three-way cylinder 11. The linkage component includes a push rod 8, one end of the push rod 8 is rotatably connected to the inside of the advancement plate 6, and the other end of the push rod 8 is rotatably connected to a connecting plate 9, and one end of the connecting plate 9 is rotatably connected to the outer wall of the rotating shaft 10;

[0027] Specifically, first, the foaming agent can be transported to the interior of the storage bin 1 for storage through the feed plate 2, and then the foaming agent can be transported to the interior of the quantitative bin 4 through the discharge pipe 3. When the interior of the quantitative bin 4 is full of foaming agent, the electric push rod 7 is started, and the output end of the electric push rod 7 drives the push plate 6 to slide on the upper surface of the workbench 21, thereby driving the piston rod 5 and the push rod 8 to slide synchronously. At this time, the movement of the push rod 8 drives the movement of the connecting plate 9 to move, and then the other end of the connecting plate 9 drives the rotating shaft 10 to rotate with itself as the center of the circle, and then the rotation of the rotating shaft 10 drives the three-way cylinder 11 to slide inside the quantitative bin 4, thereby rotating two of the holes of the three-way cylinder 11 to the channel inside the quantitative bin 4. The foaming agent can pass through the quantitative bin 4, and at the same time, the last hole of the three-way tube 11 is rotated to fit the inner wall of the quantitative bin 4. At the same time, the side of the three-way tube 11 without a through hole will block the discharge pipe 3. At the same time, through the movement of the piston rod 5, the piston at one end of the piston rod 5 is driven to slide on the inner wall of the quantitative bin 4, thereby pushing the foaming agent inside the quantitative bin 4 to the inside of the conveying pipe 12. When the electric push rod 7 is retracted, it will drive the three-way tube 11 to rotate in the opposite direction, so that the side without a through hole will block the quantitative bin 4 again, and at the same time, the discharge pipe 3 will be opened to continue to convey the foaming agent to the inside of the quantitative bin 4 for quantitative measurement. Since the storage space inside the quantitative bin 4 is limited, the quantitative effect can be achieved, thereby achieving the quantitative and conveying effects.

[0028] In another embodiment of the present invention, Figure 1 and Figure 5 As shown, one end of the quantitative bin 4 is fixedly connected to a delivery pipe 12, one end of the delivery pipe 12 is fixedly connected to a stirring bin 13, an outer wall of the stirring bin 13 is fixedly connected to a support frame 14, a lower surface of the support frame 14 is fixedly connected to a lower surface of a workbench 21, an outer wall of the stirring bin 13 is fixedly connected to a motor 15, an output end of the motor 15 is fixedly connected to a driving wheel 16, an outer wall of the driving wheel 16 is rotatably connected to the inside of the stirring bin 13, a driven wheel 17 is rotatably connected to the inside of the stirring bin 13, the driving wheel 16 is meshed with the driven wheel 17, an auger blade 18 is fixedly connected to the inside of the driving wheel 16, a stirring rod 19 is fixedly connected to the inside of the driven wheel 17, the auger blade 18 and the stirring rod 19 are both rotatably connected to the inside of the stirring bin 13, and one end of the stirring bin 13 is fixedly connected to a discharge port 20;

[0029] Specifically, the quantitatively delivered foaming agent will be delivered to the interior of the mixing chamber 13, and then the motor 15 will be started, and the output end of the motor 15 will drive the driving wheel 16 to rotate. Due to the meshing of the driving wheel 16 and the driven wheel 17, the driven wheels 17 on both sides will rotate with the rotation of the driving wheel 16, thereby driving two stirring rods 19 and an auger blade 18 to rotate. At this time, the raw materials and the foaming agent are stirred by the stirring rod 19 to make them foam. When the foaming is completed, the discharge port 20 is opened, and the auger blade 18 can further drive the formed foam to be transported and discharged.

[0030] Working principle: When the high-pressure foaming machine with quantitative feeding function is needed, the foaming agent is first transported to the storage bin 1 through the feeding plate 2, and then sent to the quantitative bin 4 through the discharge pipe 3. After the quantitative bin 4 is full, the electric push rod 7 is started to drive the push plate 6, the piston rod 5 and the push rod 8 to slide synchronously, and then through the rotation of the connecting plate 9 and the rotating shaft 10, the three-way cylinder 11 slides inside the quantitative bin 4 to achieve quantitative delivery of the foaming agent. The retraction of the electric push rod 7 causes the three-way cylinder 11 to rotate in the opposite direction, blocking the quantitative bin 4, and continuing to transport the foaming agent to the quantitative bin 4 for quantitative delivery;

[0031] In addition, the quantitatively conveyed foaming agent is sent to the mixing chamber 13, and the motor 15 is started to drive the stirring rod 19 and the auger blade 18 to rotate, so as to stir and foam the raw materials and the foaming agent. After the foaming is completed, the discharge port 20 is opened, and the formed foam is conveyed and discharged by the auger blade 18. The entire structure realizes the quantitative conveying and efficient foaming of the foaming agent through precise mechanical coordination, thereby improving production efficiency and product quality.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
