DETAILED DESCRIPTION
[0020] like Figures 1 to 7As shown, a metal extruder anti-overflow extrusion wheel includes an extrusion wheel main structure 1 made of alloy steel material, and the interior of the extrusion wheel main structure 1 is provided with two extrusion matching holes that completely penetrate the upper and lower ends, and the material is extruded through this position when in use. The upper end of the extrusion matching hole is an extrusion feed port 2, and the lower end of the extrusion matching hole is an extrusion discharge port 3. The position of the extrusion feed port 2 is provided with a cylindrical discharge safety avoidance groove 4 that fully covers it, so that the discharge port position has a larger space, and the extruded material can be timely heat-dissipated to avoid the influence of heat on the extruded material. The upper end of the extrusion wheel main structure 1 is provided with a cylindrical feed safety matching groove 5 that is in communication with the extrusion feed port 2, and this position is matched with the material conveying structure. The two extrusion matching holes are connected through a material over-conveying groove 6, so that the materials can be over-flowed with each other during the extrusion process, ensuring a higher material conveying efficiency. The lower end surface of the material over-conveying trough 6 is provided with a first reinforced anti-overflow boss 7 evenly distributed around the circumference in the outer area of the extrusion inlet 2. The lower end surface of the material over-conveying trough 6 is provided with a second reinforced anti-overflow boss 8 evenly distributed around the circumference at the outer position of the first reinforced anti-overflow boss 7. When in use, an anti-overflow structure can be formed between them, which effectively avoids the occurrence of easy overflow during the extrusion of materials. The size of the first reinforced anti-overflow boss 7 is smaller than that of the second reinforced anti-overflow boss 8, so that the structural safety of the outer position is better. The second reinforced anti-overflow boss 8 is located between two adjacent first reinforced anti-overflow bosses 7, and the width of the second reinforced anti-overflow boss 8 is greater than the distance between two adjacent first reinforced anti-overflow bosses 7, ensuring that the overall anti-overflow effect is more reliable, and they can dissipate the heat at the entrance position during the extrusion process, reducing the damage to the extrusion wheel caused by the heat during the extrusion process, and effectively improving the service life of the extrusion wheel. It adopts a brand-new structural design, by providing an avoidance space at the feed inlet and the discharge position respectively, and setting two sets of mutually cooperating boss structures at the feed inlet position. When in use, the material inlet position can effectively restrict the outward flow of the material during the extrusion process, forming an anti-overflow effect with each other, and can dissipate the heat at the feed inlet position. When in use, it can ensure that the structural stability of the extrusion wheel is better and the heat resistance is stronger, and prevent the material from rushing out directly from the feed inlet. The double feed inlets are provided with interconnected transition grooves, which can make the extrusion input efficiency of the material higher when in use, and the overall extrusion efficiency can also be effectively improved.
[0021] Preferably, the material over-conveying trough 6 is a conical structure, and the size of the upper end of the material over-conveying trough 6 is larger than that of the lower end, so that the material conveying efficiency is higher when over-fitting is performed during material extrusion.
[0022] Preferably, the second reinforced anti-overflow boss 8 and the first reinforced anti-overflow boss 7 are both cylindrical structures, which are more convenient during production and processing, have higher production efficiency, and have higher heat dissipation efficiency during use.
[0023] Preferably, the height of the second reinforced anti-overflow boss 8 and the first reinforced anti-overflow boss 7 are both less than the depth of the feed safety matching groove 5, so that the structural stability of the upper end position is better and the safety during use is more reliable.
[0024] Preferably, the height of the second reinforced anti-overflow boss 8 is greater than the height of the first reinforced anti-overflow boss 7, so that the structural strength of the outer position is better and the durability of the overall structure can be further improved.
[0025] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements or substitutions can be made without departing from the principles of the present invention. These improvements or substitutions should also be regarded as the protection scope of the present invention.
