[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0027] The core of the utility model is to provide an extrusion forming hole, and the extrusion protrusion can be used to process the extrusion groove outside the round straight surface to reduce the outer diameter of the round straight surface, so that the cooking time period and the flavor degree of the round straight surface are high.
[0028] The utility model also provides a die head mechanism of an extruded noodle machine comprising the extrusion forming hole.
[0029] The extrusion forming hole 10 provided by the utility model is used for the die head mechanism of the noodle extrusion machine, including a forming section 13, the inner circumference of the forming section 13 is protruded inwardly and provided with a plurality of extrusion protrusions 131, the extrusion protrusions 131 are used to extrude the outer circumference of the round straight surface 30 to form an extrusion groove 31 arranged along the axial direction, and the two extrusion edges of the extrusion protrusion 131 are of different lengths so that the two sides of the extrusion groove 31 can fit together after cooking to close the outer circumference of the round straight surface 30.
[0030] Please refer to Figure 1 The extrusion protrusions 131 are protruded inward from the inner circumferential surface of the forming section 13. In order to ensure the strength of the round straight surface 30 and prevent it from losing its shape during cooking, the extrusion protrusions 131 are usually evenly distributed along the circumferential direction of the forming section 13 so that the extrusion grooves 31 are evenly distributed in the circumferential direction of the round straight surface 30.
[0031] The cross-sectional area of the extrusion protrusion 131 can be set to gradually increase along the noodle conveying direction to reduce the resistance encountered when the round straight surface 30 is formed; however, in order to facilitate the processing of the extrusion forming hole 10, the extrusion protrusion 131 is usually set along the extension direction of the forming section 13, and the forming section 13 is integrally formed by wire cutting or laser cutting, such as Figure 4 shown.
[0032] Please refer to Figure 2 The extrusion protrusion 131 is used to extrude an extrusion groove 31 arranged along the axial direction on the outer peripheral surface of the round straight noodles 30. The shape and size of the extrusion groove 31 are exactly the same as those of the extrusion protrusion 131. Since the extrusion groove 31 reduces the diameter of the round straight noodles 30, the cooking time of the round straight noodles 30 is shortened, which can usually reduce more than 1 / 3 of the existing cooking time, and the noodles are easy to taste and digest;
[0033] The two extrusion edges of the extrusion protrusion 131 are of different lengths, so the two sides of the extrusion groove 31 are of different lengths. After the round straight surface 30 is cooked, the two sides of the extrusion groove 31 can fit together, so that the outer circumference of the round straight surface 30 is closed. Compared with the outer circumference of the round straight surface 30 that still has a gap, the surface roughness of the round straight surface 30 is low, which is conducive to maintaining the smoothness of the round straight surface 30.
[0034] It should be noted that the setting of the extrusion groove 31 will reduce the cross-sectional area of the round straight noodles 30, thereby affecting the strength of the round straight noodles 30. In order to avoid the round straight noodles 30 from becoming loose when cooking, the depth and total area of the extrusion groove 31 should not be too large, and must be determined based on the raw material texture and size of the round straight noodles 30 in actual production.
[0035] In this embodiment, the extrusion forming hole 10 is provided with an inwardly protruding extrusion protrusion 131, which can be extruded on the outer circumferential surface of the round straight surface 30 to form an axially arranged extrusion groove 31. The extrusion groove 31 can reduce the outer diameter of the round straight surface 30, thereby shortening the cooking time of the round straight surface 30 and improving the flavor of the round straight surface 30. In addition, the two sides of the extrusion groove 31 can be fitted together after cooking, so that the outer circumferential surface of the round straight surface 30 is closed, the surface roughness of the round straight surface 30 is low, and the smoothness of the round straight surface 30 is maintained.
[0036] In addition, the shortened cooking time makes it more convenient to eat the round straight noodles 30, thereby improving the convenience of the round straight noodles 30.
[0037] The two extrusion edges of the extrusion protrusion 131 can be set as straight lines or arcs to reduce the extrusion pressure; please refer to Figure 4 The two extrusion edges of the extrusion protrusion 131 are both arc-shaped, and the rotation directions of the two extrusion edges are the same, and the rotation directions of the corresponding extrusion grooves 31 are consistent, so that the cross-sectional shape of the round straight surface 30 is an impeller shape, which is more conducive to the closure of the outer contour of the round straight surface 30 after cooking.
[0038] The number, shape, size and distribution of the extrusion protrusions 131 on the extrusion forming hole 10 need to be determined according to the material and size of the round straight surface 30 in actual production; usually, the extrusion protrusions 131 are evenly arranged along the inner circumference of the forming section 13, and the number of the extrusion protrusions 131 is 3-5.
[0039] The larger the outer diameter of the circular straight surface 30, the greater the number of extrusion protrusions 131 in the corresponding extrusion forming hole 10, and the greater the length of the extrusion protrusions 131 protruding inward; conversely, the smaller the outer diameter of the circular straight surface 30, the smaller the number of extrusion protrusions 131 in the corresponding extrusion forming hole 10, and the smaller the length of the extrusion protrusions 131 protruding inward.
[0040] According to actual test results, in order to ensure the strength of the circular straight surface 30, the total area of the extrusion protrusion 131 in the cross section perpendicular to the noodle conveying direction needs to be less than 15% of the cross-sectional area of the circular inner circumference of the forming section 13;
[0041] In order to ensure that the outer circumference of the round straight surface 30 can remain closed after being cooked, the angle between the two extrusion edges of the extrusion protrusion 131 needs to be less than or equal to 40°, that is, the angle between the two sides of the extrusion groove 31 on the round straight surface 30 is less than or equal to 40°. In actual production, the angle of the extrusion groove 31 is usually set to about 35°.
[0042] On the basis of the above embodiment, in order to reduce the resistance of the round straight surface 30 during extrusion, the extrusion forming hole 10 can be provided with an input section 11, a transition section 12 and a forming section 13 in sequence along the noodle conveying direction, the axes of the input section 11, the transition section 12 and the forming section 13 are collinear, and the inner diameters of the input section 11, the transition section 12 and the forming section 13 gradually decrease along the noodle conveying direction.
[0043] Please refer to Figure 4 The extrusion forming hole 10 is provided with an input section 11, a transition section 12 and a forming section 13 in sequence along the noodle conveying direction, wherein the input section 11 is a cylindrical hole, used for preliminary extrusion forming of the dough to form a rough round straight surface with a consistent cross-sectional shape; the transition section 12 is a truncated cone hole with a gradually decreasing inner diameter, used for extruding and stretching the rough round straight surface to gradually reduce its outer diameter to form a round straight surface 30 with the same design size; the forming section 13 is a special-shaped hole with an extrusion protrusion 131 therein, used for further extrusion and stretching the round straight surface 30 to form an extrusion groove 31 arranged along the axial direction on the outer peripheral surface of the round straight surface 30.
[0044] In this embodiment, by providing an input section 11, a transition section 12 and a forming section 13 with gradually decreasing inner diameters, the dough can be gradually extruded and thinned to form a round straight surface 30, and an extrusion groove 31 is extruded on the outer circumference of the round straight surface 30, thereby reducing the resistance of the forming section 13 at the end of the extrusion forming hole 10 and facilitating the extrusion forming process of the round straight surface 30.
[0045] In addition to the above-mentioned extrusion forming holes 10, the utility model also provides a die head mechanism of an extrusion noodle machine including the extrusion forming holes 10 disclosed in the above-mentioned embodiment. The die head mechanism of the extrusion noodle machine includes a die head 20. The die head 20 is evenly provided with a plurality of circles of extrusion holes along the radial direction. Each circle of extrusion holes is evenly provided with a plurality of extrusion holes along the circumferential direction. The extrusion holes are the extrusion forming holes 10 disclosed in the above-mentioned embodiment.
[0046] Please refer to Figure 3 The radial distance between any two adjacent circles of extrusion holes is the same, and the circumferential distance between any two adjacent extrusion holes in the same circle is the same. The specific values of the above-mentioned radial distance and axial distance are determined according to factors such as the material and size of the die 20 and the size of the extrusion molding hole 10 in actual production to ensure the structural strength of the die 20.
[0047] It should also be noted that the distance between the extrusion forming hole 10 and the center of the die head 20 will affect the extrusion pressure of the extrusion forming hole 10 on the circular straight surface 30 , and further affect the exit speed of the circular straight surface 30 .
[0048] Considering that the central extrusion pressure of the die 20 is large and the exit speed of the circular straight surface 30 is too fast, preferably, the distance from the extrusion hole closest to the center of the die 20 to the center of the die 20 can be set to be greater than 15% of the radius of the die 20.
[0049] There is no extrusion hole in the center of the die head 20 to avoid excessive extrusion pressure in the center of the die head 20 affecting the extrusion pressure distribution at the outer edge, so that the extrusion pressure at each location of the die head 20 is relatively uniformly arranged along the radial direction. The structures of other parts of the die head mechanism are referred to the prior art and will not be described in detail herein.
[0050] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
[0051] The die head mechanism and extrusion forming hole of the extruded noodle machine provided by the utility model are introduced in detail above. Specific examples are used in this article to illustrate the principle and implementation method of the utility model. The description of the above embodiment is only used to help understand the method and core idea of the utility model. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
