The tank body 501, feed bin 502, discharge bin 503, guide plate 504, electric push rod 505, movable baffle 506, drive motor 507, stirring shaft 508 and stirring blade 509 provided by the premixing structure 5 facilitate the stirring of the polyurethane raw material before extrusion, thereby avoiding the occurrence of agglomeration or precipitation of the polyurethane raw material, solving the problem of material piling due to agglomeration or precipitation during extrusion, thereby ensuring the efficiency of the extrusion work, meeting people's work needs, and worthy of popularization and use.

[0025] A groove 304 is formed on one side of the sealing cover 301 , and the groove 304 matches with the discharge bin 503 , thereby facilitating the sealing cover 301 to be effectively installed on the top of the feed hopper 2 .

[0026] A handle 305 is fixedly connected to the top of the sealing cover 301 , and the handle 305 is distributed in a “concave” shape, thereby facilitating the lifting of the sealing cover 301 .

[0027] The filter plate 303 forms a telescopic structure with the sealing cover 301 through the telescopic springs 302, and there are four telescopic springs 302 symmetrically distributed in pairs, which is conducive to the elastic movement of the filter plate 303 driven by the telescopic springs 302, thereby realizing vibration screening.

[0028] An electric push rod 505 is fixedly connected to the inner wall of the top of the tank body 501, and a movable baffle 506 is fixedly connected to the bottom of the electric push rod 505, and the size of the movable baffle 506 is larger than the size of the discharge bin 503. The feed bin 502, the discharge bin 503 and the guide plate 504 are all distributed in an inclined shape, and the bottom of the movable baffle 506 is provided with an inclined slope with the same angle as the guide plate 504, which is conducive to the sliding of the movable baffle 506 by the electric push rod 505, so that the movable baffle 506 opens or closes the discharge bin 503.

[0029] The stirring blades 509 are distributed in a plurality of groups at equal intervals, and each group of stirring blades 509 has a plurality of stirring blades distributed at equal angles, thereby facilitating improving the stirring effect.

[0030] Working principle: When in use, firstly, the polyurethane raw material is placed into the interior of the tank body 501 through the feed bin 502, and then the drive motor 507 is started, so that the drive motor 507 drives the stirring shaft 508 to rotate, and the stirring shaft 508 drives the stirring blades 509 to rotate, so that the stirring blades 509 stir the polyurethane raw material, thereby preventing the polyurethane from agglomerating or precipitating. Subsequently, the electric push rod 505 is started, so that the electric push rod 505 drives the movable baffle 506 to slide, and then the movable baffle 506 facilitates the opening or closing of the discharge bin 503. When the discharge bin 503 is opened, the polyurethane raw material flows into the interior of the sealing structure 3 through the discharge bin 503 under the guidance of the guide plate 504.

[0031] During the flow, the polyurethane raw material will exert pressure on the filter plate 303, so that the filter plate 303 drives the telescopic spring 302 to telescopically deform, thereby facilitating the filter plate 303 to vibrate and screen, so that the screened polyurethane raw material falls into the interior of the feed hopper 2 and finally flows into the interior of the extruder body 1 for extrusion. By screening the polyurethane raw material, the agglomerated polyurethane raw material is further prevented from entering the interior of the extruder body 1. Subsequently, the sealing cover 301 is opened by pulling the handle 305, so that the sealing cover 301 drives the filter plate 303 to be disassembled, thereby facilitating the removal and reprocessing of the polyurethane raw material retained after screening, thereby effectively ensuring the working efficiency of the extruder body 1.
