The utility model discloses a flour extrusion head capable of uniformly discharging, which comprises an extrusion cylinder 1, a material guide plate 2 and a heat insulation block 3. An inner cavity 11 communicated with a feed inlet 12 and a discharge outlet 13 is formed in the middle of the extrusion barrel 1, the inner cavity is used for guiding flour, the length of the inner cavity 11 is gradually increased from the feed inlet 12 to the discharge outlet 13, and the width of the inner cavity is gradually narrowed from the feed inlet 12 to the discharge outlet 13, so that the discharge state of the flour is adjusted. Since the flour extrusion head is generally arranged transversely and inclined upwards, the length of the inner cavity 11 is a left-right transverse direction, and the width of the inner cavity 11 is an up-down vertical direction. The material guiding plate 2 is covered on the material outlet 13. The heat insulation blocks 3 are arranged in pairs, are arranged at two ends of the extrusion cylinder 1 in the length direction and are close to the discharge hole 13.

The material guiding plate 2 may be fixed to the extrusion barrel 1 by a screw 16 or the like, or may be connected to the extrusion barrel 1 by a detachable structure, or may be hinged to the extrusion barrel 1. A plurality of material guiding openings 21 are formed in the material guiding plate 2, and the arrangement and the number of the material guiding openings 21 can be designed according to the needs. In this embodiment, the material guiding openings 21 are rectangular and are uniformly and alternately distributed along the length direction of the inner cavity 11.

At least two heat preservation blocks 3 can be in a structure of a plurality of overlapped structures. For example, when the heat preservation blocks 3 are four, two heat preservation blocks 3 are overlapped and arranged at one end of the heat preservation blocks, and the other two heat preservation blocks 3 are overlapped and arranged at the other end of the heat preservation blocks, so that the heat preservation stroke can be carried out when the flour at two sides flows, and the uniformity of the flowing of the flour raw materials is ensured.

Because flour is in the environment of higher temperature always in the production process, when it passes through the extrusion head, the structure of extrusion head makes the flour of both sides cool down very fast, absorbs outside water gas in discharge gate 13 department easily, leads to extrusion head exit both sides's flour to take place to block easily and pile up, causes the hindrance to the flow of flour for the flour at extrusion head middle part flows very fast and the flow of both sides flour is slower in actual production process, and the flour ejection of compact is inhomogeneous, has influenced the water conservancy diversion effect of extrusion head.

The inner side surface 31 of the heat insulation block 3 is an inclined plane coplanar with the side wall of the inner cavity 11, namely, the inner side surface 31 of the heat insulation block 3 is positioned in the same plane with the side wall of the inner cavity 11, so that the blocking of flour during passing is avoided.
