Generally speaking, it has excellent elasticity, softness, elongation and compression strength, good chemical stability, resistance to many solvents and oils; excellent wear resistance, 20 times greater than that of natural sponge; and excellent processability, thermal insulation, adhesion and other properties. It is a high-performance cushioning material.

[0003] The existing polyurethane foam plastic raw material storage device can only store the raw materials, and needs to be transferred to other processing devices for processing during processing. When dumping, there are many raw materials in the original storage device that cannot be emptied cleanly, resulting in waste of raw materials and making the processing process cumbersome. During the processing, the existing stirring mechanism is relatively fixed and cannot mix the raw materials together well. After processing, the storage box cannot remove the residual raw materials inside, and can only be replaced with a new storage box for processing, which increases the processing cost and causes waste of resources.

DETAILED DESCRIPTION

[0022] The technical solution of the present invention is further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0023] A foam product production device, comprising a barrel 1:

[0024] A round tube 2 driven by a motor 3 is arranged in the barrel body 1, the top of the round tube 2 is sealed, a sleeve 4 is arranged on the bottom of the barrel body 1 and is sleeved on the round tube 2, an air inlet pipe 5 is arranged on the bottom wall of the barrel body 1 in the opening of the sleeve 4, a plurality of strip openings 6 are arranged in parallel on the side wall of the round tube 2, a stirring paddle 7 is arranged in the barrel body 1, which passes through the strip openings 6 and is connected to a vertical tube 8 in the round tube 2, the top of the vertical tube 8 is sealed, a ventilation channel 9 communicating with the vertical tube 8 is arranged in the stirring paddle 7, and ventilation holes communicating with the ventilation channel 9 are evenly arranged on the outer wall of the stirring paddle 7;

[0025] A semicircular fixing seat I10 and a fixing seat II11 are respectively arranged on both sides of the inner bottom of the vertical tube 8, wherein the fixing seat I10 is located above the fixing seat II11 and is fixedly connected to the inner wall of the vertical tube 8, wherein the bottom end of the fixing seat I10 and the top end of the fixing seat II11 are in the same horizontal plane, and the bottom of the fixing seat II11 is fixedly connected to the inner wall of the sleeve 4 through a cross bar 12, and the cross bar 12 is located below the circular tube 2. In this embodiment, the fixing seat II11 is located at the bottom of the lowest strip opening 6, and a circular structure that seals the internal opening of the vertical tube 8 is formed between the bottom end surface of the fixing seat I10 and the top end surface of the fixing seat II11.

[0026] like Figure 1 As shown, a bearing for fixing the top of the round tube 2 is arranged on the top cover plate of the barrel body 1 , a toothed disc 13 is arranged on the top of the round tube 2 , a gear 14 meshing with the toothed disc 13 is arranged on the toothed disc 13 , and the output shaft of the motor 3 is connected to the gear 14 .

[0027] In this embodiment, a feed pipe is arranged on the top cover plate of the barrel body 1, and a discharge pipe is arranged on the bottom wall of the barrel body 1.

[0028] In this embodiment, the diameter of the circular tube 2 matches the inner diameter of the sleeve 4 , the stirring paddle 7 is located above the sleeve 4 , and the diameter of the vertical tube 8 matches the inner diameter of the circular tube 2 .

[0029] An annular seat 15 located inside the barrel body 1 is arranged on the bottom end surface of the top cover plate of the barrel body 1, and a circular ring 16 located inside the barrel body 1 is arranged on the annular seat 15, and a circle of arc grooves are correspondingly arranged on the inner wall of the circular ring 16 and the outer wall of the annular seat 15, wherein a plurality of metal balls 17 are arranged in two groups of arc grooves, and a plurality of groups of scrapers 18 in a right-angled trapezoid are axially arranged at the bottom of the circular ring 16, and the upper bottom end of the scraper 18 is fixedly connected to the bottom end surface of the circular ring 16, and a groove for fixing a rubber scraper 19 is axially arranged on the right-angle side wall of the scraper 18, and the scraper 19 contacts the inner wall of the barrel body 1, and the stirring paddle 7 is fixedly connected to the vertical pipe 8, wherein the lengths of the plurality of groups of stirring paddles 7 are equal, and the end of the lowest stirring paddle 7 extends to one side of the bottom of the hypotenuse end of the scraper 18 and is arranged in contact with its side wall.

[0030] When in use, the material is stored in the barrel body 1, and other matching raw materials are transported to the barrel body 1 when processing is required. At this time, the motor 3 drives the round tube 2 to rotate through the gear 14 and the toothed disc 13, and the round tube 2 drives the stirring paddle 7 to rotate through the strip opening 6 on its side wall, thereby stirring and mixing the material in the barrel body 1. At the same time, a strong air flow is injected into the sleeve 4 through the air inlet pipe 5. At this time, the strong air pressure flows upward and circulates in the vertical pipe 8. At this time, the air flow in the vertical pipe 8 above it is blocked by the fixed seat I10, which causes the air flow to circulate. The opening is reduced. Due to the large air intake and small air outlet, the strong air pressure will push the vertical tube 8 to flow slowly upward in the circular tube 2. At the same time, the vertical tube 8 also drives the stirring paddle 7 in the rotating process to move slowly upward in the strip opening 6. When the airflow introduced by the air intake pipe 5 is reduced, the vertical tube 8 will drive the stirring paddle 7 to move slowly downward in the strip opening 6, so that the stirring paddle 7 in the rotating process can cover different upper and lower areas in the barrel body 1, and then stir and mix the materials in different upper and lower areas in the barrel body 1 to improve the mixing efficiency and effect.

[0031] At the same time, the upward airflow in the vertical pipe 8 can be distributed in a number of air permeable channels 9 and evenly discharged from the air holes on the stirring paddle 7 during the rotation process, thereby preventing pressure buildup in the vertical pipe 8. As the stirring paddle 7 rotates and moves up and down, the discharged gas can cover the materials in different areas of the barrel body 1, thereby blowing and surging the materials. While having a certain mixing effect on the materials, the rotating stirring paddle 7 can better stir the materials to make them fully mixed.

[0032] like Figure 1 As shown, when the air intake volume of the air intake pipe 5 is small and cannot blow the vertical pipe 8 upward through the fixed seat I10, the circular tube 2 drives the vertical pipe 8 and the stirring paddle 7 to rotate, and the vertical pipe 8 drives the fixed seat I10 to rotate to switch its position, so that the fixed seat I10 and the fixed seat II11 seal the opening of the vertical pipe 8, or open the bottom opening of the vertical pipe 8, thereby indirectly intermittently supplying air to the vertical pipe 8, the air permeable channel 9 and the barrel body 1 to stir the internal materials.

[0033] like Figure 1As shown in the figure, when the bottom stirring paddle 7 rotates, it pushes the scraper 18 to drive the metal ball 17 on the ring 16 to slide in the arc groove. At this time, the scraper strip 19 on the scraper 18 can scrape the inner wall of the barrel body 1. However, as long as the bottom stirring paddle 7 moves up slightly, its end will not abut against the side wall of the scraper 18, so it will not drive the scraper 18 and other components to rotate, so as to prevent the stirring paddle 7 from driving the scraper 18 to rotate together when the material in the barrel body 1 is quickly stirred and mixed, causing intense friction on the inner wall of the barrel body, thereby damaging the barrel body. 1, and the scraper 18 will not affect the rotation of the stirring paddle 7. Only when the stirring paddle 7 at the bottom is reset and the air inlet pipe 5 does not introduce gas or the gas flow is small, the motor 3 drives the stirring paddle 7 to rotate through the round tube 2 and other components, and the stirring paddle 7 pushes the scraper 18 to drive the scraper bar 19 to rotate in the barrel body 1, thereby scraping the inner wall to prevent the material from adhering. At this time, when the discharge pipe is opened to discharge the material, the material can be discharged quickly from it, and the problem of the material adhering to the inner wall of the barrel body 1 and being difficult to clean and discharge will not occur.

[0034] The present invention is described in detail above, but the contents are only preferred embodiments of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of application of the present invention should still fall within the scope of the patent coverage of the present invention.
