Description

Technical Field

[0001] This utility model relates to the field of extruder technology, specifically to an extruder for producing noodles for making twisted dough sticks. Background Technology

[0002] Twisted dough sticks are made from flour, water, oil, sugar, and other ingredients. Currently, apart from manual production, most twisted dough sticks are made using twisted dough stick machines. A twisted dough stick machine is a mechanical device that extrudes dough through a mold. With the help of a noodle extruder, the dough is extruded into twisted dough sticks, thereby improving the production efficiency and quality of twisted dough sticks.

[0003] Due to the unique shape of twisted dough sticks, the extrusion head is designed as a planetary structure, allowing the extruded noodles to rotate on their own axis while revolving around the planet, thus twisting multiple extruded noodles into a twisted shape. However, current extrusion heads are mounted rotatingly with the machine body and require a separate drive unit, resulting in a complex structure that is inconvenient for disassembly and maintenance. Because the extrusion head contains gear sets and there are gaps between the rotating components, even with sealing components, regular maintenance is still necessary after prolonged use. Therefore, we propose a noodle extruder for producing twisted dough sticks. Utility Model Content

[0026] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] Reference Figures 1 to 8 This utility model provides a technical solution: a noodle extruder for making twisted dough sticks, including a frame 1, a housing 3 on the top of the frame 1, a hopper 4 detachably mounted on the top of the housing 3, a flange edge on the bottom edge of the hopper 4, the flange edge being bolted to the top of the housing 3, the hopper 4 being bucket-shaped, and in actual use, the dough is placed in the hopper 4, and the dough will be placed in the housing 3.

[0028] An extrusion cylinder 5 is detachably mounted on one side of the casing 3; that is, a flange is provided at the end of the extrusion cylinder 5, and the flange is fastened to the casing 3 by bolts. Figure 8 As shown, the extrusion cylinder 5 is connected to the interior of the casing 3. Figure 8 As shown, a spiral extrusion shaft 26 is provided inside the housing 3 and the extrusion cylinder 5. The diameter of the spiral extrusion shaft 26 matches the internal size of the extrusion cylinder 5, allowing for better extrusion results. The end of the spiral extrusion shaft 26 away from the extrusion cylinder 5 is rotatably connected to the frame 1, and the end of the spiral extrusion shaft 26 is driven to rotate by a drive device. Figure 8 As shown, the drive device includes a first motor 2 located below the frame 1. The shaft of the first motor 2 and the end of the spiral extrusion shaft 26 are both equipped with pulleys, and the two pulleys are connected by a belt. Since the belt and pulley are located at one end of frame 1, to prevent foreign objects from getting caught in the belt, such as... Figure 2 As shown, a protective cover 19 can be placed on the belt and pulley, and the edge of the protective cover 19 can be fastened to the frame 1 with bolts.

[0029] It should be noted that twisted dough sticks have a specific spiral shape, so the focus of this application is on how to extrude the dough into a spiral shape, specifically achieved through the following structure: like Figure 1 As shown, an annular seat 6 is detachably installed at the end of the extrusion cylinder 5. Specifically, a flange is provided at one end of the annular seat 6 and the end of the extrusion cylinder 5, and the two flanges are connected by bolts, making the annular seat 6 easy to disassemble. A mounting cavity 24 is coaxially provided at the end of the annular seat 6 near the extrusion cylinder 5. A disc-shaped seat 23 is rotatably installed inside the end of the annular seat 6 near the extrusion cylinder 5. Specifically, the disc-shaped seat 23 is rotatably installed within the mounting cavity 24. The disc-shaped seat 23 and the mounting cavity 24 are connected by a bearing. To prevent material from entering the bearing, a sealing component (such as...) is provided at the opening of the mounting cavity 24. Figure 8 (At the location indicated by the middle arrow A) Multiple extrusion tubes 8 are vertically distributed on the surface of the disc-shaped seat 23. There are at least two extrusion tubes 8, arranged in a ring, with one end rotatably mounted on the disc-shaped seat 23. The extrusion tubes 8 are distributed around the center periphery of the disc-shaped seat 23. Bearing holes are provided at the locations of the extrusion tubes 8 and their corresponding positions on the disc-shaped seat 23. One end of each extrusion tube 8 is connected to a bearing hole via a bearing, and a sealing assembly is also provided at the end of the bearing hole facing the extrusion cylinder 5. Figure 5 As shown, the extrusion tube 8 must be connected to the extrusion cylinder 5; like Figure 4 and Figure 6 As shown, an internal gear ring 21 is provided inside the annular seat 6, and a drive gear 22 is provided on each extrusion tube 8, with each drive gear 22 meshing with the internal gear ring 21. Figure 5 and Figure 7As shown, a drive shaft 20 is coaxially mounted on one end of the disc-shaped seat 23 near the extrusion cylinder 5. The drive shaft 20 is coaxial with the extrusion cylinder 5 and is placed in the cavity at the end of the spiral extrusion shaft 26. The shape and size of the cavity match those of the drive shaft 20. After the drive shaft 20 is placed in the cavity, the two are connected by a key, as shown. Figure 5 and Figure 7 As shown, at least one keyway is provided on the surface of the drive shaft 20 and at least one keyway is also provided in the cavity. The inner and outer keyways can be connected by a flat key. Alternatively, a spline shaft can be provided at the end of the drive shaft 20 and a spline hole can be provided at the end of the spiral extrusion shaft 26. This not only allows the disc seat 23 to support the end of the spiral extrusion shaft 26, but also allows the spiral extrusion shaft 26 to drive the disc seat 23 to rotate. Therefore, when the spiral extrusion shaft 26 rotates, it can drive the dough to move along the extrusion cylinder 5 towards the annular seat 6. When the dough moves to the disc seat 23, the dough will be squeezed into each extrusion tube 8. Since the disc seat 23 is driven to rotate by the spiral extrusion shaft 26, the disc seat 23 will drive each extrusion tube 8 to rotate around the inner gear ring 21. Since the inner gear ring 21 is connected to the core of the drive gear 22, each extrusion tube 8 rotates while also rotating on its own axis. Therefore, the noodles extruded from each extrusion tube 8 will be spirally intertwined. To increase the number of noodles extruded from the end of the extrusion tube 8, a discharge head 7 is detachably installed at the end of each extrusion tube 8. The discharge head 7 is threaded onto the head of the extrusion tube 8, and the end of the discharge head 7 is provided with at least one discharge hole, which can be a single hole, double hole, etc. The end of each extrusion tube 8 extends to the outside of the annular seat 6, which facilitates the replacement of the discharge head 7.

[0030] To prevent the twisted noodles from piling up below the extrusion cylinder 5, such as... Figure 1 and Figure 2 As shown, a conveyor is provided below the end of the extrusion cylinder 5. The conveyor includes a conveyor belt 9. The end of the conveyor belt 9 near the extrusion cylinder 5 is supported by a first drive roller 10. Both ends of the first drive roller 10 are rotatably mounted on the extension frame 15. One end of the first drive roller 10 is connected to a second motor 17. The second motor 17 is mounted on the extension frame 15. One end of the extension frame 15 is connected to the frame 1. The conveyor belt 9 is supported by a second drive roller 13 at the end away from the extrusion cylinder 5. Both ends of the second drive roller 13 are rotatably mounted on the mounting base 12. Mounting base 12 is located at the end of extension bracket 15 and the two are connected by a tensioning mechanism, such as Figure 3As shown, the tensioning mechanism includes adjusting screws 14 installed on both sides of the mounting base 12. The adjusting screws 14 are located on the side of the extension frame 15. Each adjusting screw 14 is movably placed inside the adjusting seat 18. The adjusting seats 18 are all installed on the side of the extension frame 15, and both ends of the adjusting seat 18 are provided with adjusting nuts. The adjusting nuts are threaded onto the adjusting screws 14. When the adjusting nuts are loosened, the adjusting screws 14 can extend and retract along the adjusting seat 18. Therefore, the distance between the first drive roller 10 and the second drive roller 13 can be adjusted at this time, thereby adjusting the tension of the conveyor belt 9 and preventing the conveyor belt 9 from becoming loose. Based on the above embodiments, further optimization can be made. In order to prevent the conveyor belt 9 from sinking and bending, a support plate 11 is provided inside the conveyor belt 9. The support plate 11 is used to support the conveyor belt 9 flat. The two sides of the support plate 11 are set on the extension frame 15 by support legs.

[0031] Based on the above embodiments, further optimization is possible. The bottom of the extrusion cylinder 5 is provided with a support 25, and the bottom of the support 25 is detachably connected to the frame 1. That is, the bottom of the support 25 is fastened to the frame 1 by bolts. Since the extrusion cylinder 5 has a certain length, the support 25 can support the extrusion cylinder 5, making the extrusion cylinder 5 more stable.

[0032] Finally, it should be noted that, firstly, the annular seat 6 and its internal disc seat 23 and other components constitute the twist extrusion head, which is easy to disassemble, that is, the annular seat 6 can be disassembled, at which point the internal parts of the annular seat 6 can be maintained. Secondly, the extrusion cylinder 5 is easy to disassemble, which facilitates the maintenance of the spiral extrusion shaft 26; Finally, a control cabinet 16 is also installed inside the frame 1. The control cabinet 16 is electrically connected to the first motor 2 and the second motor 17 respectively.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
