[0022] This utility model embodiment provides a novel rice flour extrusion molding device, such as... Figure 1-5As shown, the novel rice noodle extrusion molding device includes: a mounting frame 1; an extrusion outer cylinder 2, which is fixedly mounted on the mounting frame 1, and an extrusion inner cylinder 3 is detachably installed inside the extrusion outer cylinder 2, with multiple extrusion holes 4 at the bottom of the extrusion inner cylinder 3; a cooling box 5, which is fixedly mounted on the mounting frame 1 and located directly below the extrusion outer cylinder 2, with guide rods 6 slidably mounted on both sides of the cooling box 5, one end of each guide rod 6 extending into the cooling box 5 and fixedly mounted with a cooling frame 7; an extrusion mechanism, which is mounted on the mounting frame 1 and used to extrude the rice noodle clump inside the extrusion inner cylinder 3; and a disassembly mechanism, which is mounted on the extrusion outer cylinder 2 and the extrusion inner cylinder 3 and used to replace the extrusion inner cylinder 3.

[0023] In this embodiment, the rice flour dough is placed into the extrusion cylinder 3, and the extrusion mechanism is activated. The extrusion mechanism extrudes the rice flour dough inside the extrusion cylinder 3. Under pressure, the rice flour dough is extruded through multiple extrusion holes 4 at the bottom of the extrusion cylinder 3 to form rice flour strips. The extruded rice flour strips fall into the cooling frame 7 below. After the rice flour strips fall into the cooling frame 7, water can be injected into the cooling box 5 to cool them, or they can be cooled by air, so as to facilitate subsequent processing or storage. After the rice flour is extruded and formed, it is still at a relatively high temperature and its internal structure is not completely stable. Water cooling can quickly reduce the temperature of the rice flour and fix its shape. The device shapes and strengthens the rice noodles, preventing deformation or breakage during subsequent processing or packaging. Water washing and cooling also reduce stickiness between rice noodles, resulting in straight, full, and uniformly shaped noodles that do not clump or bend, thus improving overall product quality. When it is necessary to replace the inner extrusion cylinder 3 with a different specification, the original inner extrusion cylinder 3 can be removed from the outer extrusion cylinder 2 using a disassembly mechanism, and a new inner extrusion cylinder 3 can be installed. This allows for quick replacement of the inner extrusion cylinder 3 with different specifications according to the production needs of different rice noodle products, achieving the goal of producing rice noodles of different shapes and thicknesses, and improving the versatility and flexibility of the device.

[0024] In a further preferred embodiment of this utility model, the extrusion mechanism includes a hydraulic rod 8 and an extrusion plate 9. The hydraulic rod 8 is fixedly installed on the mounting frame 1, and the extrusion plate 9 is connected to the output rod of the hydraulic rod 8 through a coupling. The extrusion plate 9 is adapted to the extrusion inner cylinder 3.

[0025] In this embodiment, the rice noodle dough is placed into the extrusion cylinder 3, and the hydraulic rod 8 is activated. The output rod of the hydraulic rod 8 extends, driving the extrusion plate 9 to move downward. The extrusion plate 9 enters the extrusion cylinder 3 and applies pressure to the rice noodle dough. Under pressure, the rice noodle dough is extruded through multiple extrusion holes 4 at the bottom of the extrusion cylinder 3 to form rice noodle strips. The hydraulic rod 8 provides power, and the hydraulic transmission has the characteristics of large output force and stable operation, which can provide stable and strong pressure to the extrusion plate 9, ensuring that the rice noodle dough can be smoothly extruded through the extrusion holes 4, ensuring the stability and consistency of rice noodle forming. The movement of the extrusion plate 9 is controlled by the hydraulic rod 8. The operator only needs to control the start and stop of the hydraulic rod 8 to realize the extrusion forming of rice noodles. The operation is simple and convenient, improving production efficiency.

[0026] In a further preferred embodiment of this utility model, the disassembly mechanism includes a fixing groove 10, a compression spring 11, a locking block 12, a pull rod 13, a fixing block 14, and a locking groove 15. The fixing groove 10 is disposed on the inner wall of the extrusion outer cylinder 2. The compression spring 11 is fixedly installed in the fixing groove 10. The locking block 12 is fixedly installed at one end of the compression spring 11. The pull rod 13 is fixedly installed on the locking block 12. The fixing block 14 is fixedly installed on one side of the extrusion inner cylinder 3. The locking groove 15 is disposed on the fixing block 14 and is engaged with the locking block 12.

[0027] In this embodiment, the inner extrusion cylinder 3 is aligned with the outer extrusion cylinder 2 and slowly lowered. During the insertion process, the fixing block 14 on one side of the inner extrusion cylinder 3 contacts the locking block 12 in the fixing groove 10 on the inner wall of the outer extrusion cylinder 2. Due to the compression of the locking block 12 by the fixing block 14, the compression spring 11 is compressed, and the locking block 12 moves into the fixing groove 10 to make room for the fixing block 14. When the locking groove 15 on the fixing block 14 moves to the position corresponding to the locking block 12, the compression spring 11 restores its deformation, pushes the locking block 12 out, and locks it into the locking groove 15, thereby achieving the engagement of the locking groove 15 and the locking block 12, thus fixing the inner extrusion cylinder 3 inside the outer extrusion cylinder 2. When it is necessary to replace the inner extrusion cylinder 3, the pull rod 13 is pulled outward. The pull rod 13 drives the locking block 12 to move, causing the locking block 12 to disengage from the locking groove 15. At the same time, the compression spring 11 is further compressed. The inner extrusion cylinder 3 is no longer restricted by the locking block 12 and can be directly removed from the outer extrusion cylinder 2. When installing a new inner extrusion cylinder 3, the above installation steps can be repeated. Through the engagement of the locking block 12 and the slot 15 and the operation of the pull rod 13, the quick installation and disassembly of the inner extrusion cylinder 3 are realized. During the production process, when it is necessary to change to a different specification of inner extrusion cylinder 3 to produce rice noodles of different shapes or thicknesses, the operator can quickly complete the change, which greatly saves time and labor costs and improves production efficiency. The elasticity of the compression spring 11 makes the locking block 12 tightly inserted into the slot 15, ensuring the fixation effect of the inner extrusion cylinder 3 in the outer extrusion cylinder 2. When the extrusion mechanism extrudes the rice noodle dough, the inner extrusion cylinder 3 will not shake or shift, ensuring the stability and reliability of the rice noodle extrusion molding process and improving the quality of rice noodle products.

[0028] In a further preferred embodiment of the present invention, a drive motor 16 is fixedly installed on one side of the cooling box 5, and a cam 17 is rotatably installed on one side of the cooling box 5. The cam 17 is fixed to the output shaft of the drive motor 16 through a coupling. A wheel 18 is rotatably installed at one end of the guide rod 6, and the wheel 18 is in contact with the cam 17.

[0029] In this embodiment, the rice noodles are extruded through the extrusion hole 4 at the bottom of the inner extrusion cylinder 3 and fall into the cooling frame 7. The drive motor 16 is started, and the output shaft of the drive motor 16 drives the cam 17 to rotate. Since the wheel 18 is in contact with the cam 17, the rotation of the cam 17 will push the wheel 18 to move, which in turn drives the guide rod 6 to slide on both sides of the cooling box 5, so that the cooling frame 7 reciprocates in the cooling box 5. This movement mode allows the rice noodles to continuously change position during the cooling process and fully contact the cooling medium in the cooling box 5, avoiding the problems of local overheating or uneven cooling, greatly improving the uniformity of rice noodle cooling, and helping to ensure the quality of rice noodle products.

[0030] In a further preferred embodiment of this utility model, a return spring 19 is provided on the guide rod 6, and the two ends of the return spring 19 are respectively fixed to the cooling box 5 and the cooling frame 7.

[0031] In this embodiment, the return spring 19 works in conjunction with the cam 17 to drive the cooling frame 7 to reciprocate. When the cam 17 pushes the cooling frame 7 to move, the elastic force of the return spring 19 can make the cooling frame 7 return to its initial position smoothly, ensuring the stability and regularity of the reciprocating motion of the cooling frame 7 and avoiding adverse effects on the cooling effect of rice noodles due to unstable motion.

[0032] In a further preferred embodiment of the present invention, the inner wall of the extrusion outer cylinder 2 is provided with an installation groove 20, and a heating plate 21 is fixedly installed in the installation groove 20.

[0033] In this embodiment, the power supply to the heating plate 21 is turned on, and the heating plate 21 begins to heat up, preheating the inside of the extrusion outer cylinder 2. After the inside of the extrusion outer cylinder 2 is preheated to a suitable temperature, the rice flour dough is placed into the extrusion inner cylinder 3, and the extrusion mechanism is started. The output rod of the hydraulic rod 8 extends, driving the extrusion plate 9 to move downward. The extrusion plate 9 enters the extrusion inner cylinder 3 and applies pressure to the rice flour dough. Because the heating plate 21 on the inner wall of the extrusion outer cylinder 2 continues to heat up, the rice flour dough in the extrusion inner cylinder 3 can maintain a suitable temperature during the extrusion process, preventing the rice flour from hardening due to excessively low temperature and becoming difficult to extrude.

[0034] In a further preferred embodiment of the present invention, an insert plate 22 is fixedly installed on one side of the extrusion outer cylinder 2, an insert rod 23 is slidably installed on the insert plate 22, and one end of the pull rod 13 is provided with an insertion hole 24 that is adapted to the insert rod 23.

[0035] In this embodiment, when it is necessary to replace the inner extrusion cylinder 3, the pull rod 13 is pulled outward so that the insertion hole 24 on the pull rod 13 corresponds to the insertion rod 23, and the insertion rod 23 is inserted into the insertion hole 24 to fix the pull rod 13, so as to prevent the compression spring 11 from rebounding and affecting the disassembly and installation of the inner extrusion cylinder 3.

[0036] In summary, compared with related technologies, this device achieves high efficiency in rice noodle extrusion, adapts to different product specifications and production needs, maintains a suitable temperature for the rice noodles during extrusion, improves extrusion performance, and results in uniform texture and good taste. Furthermore, it drives the rice noodles in reciprocating motion after extrusion, ensuring uniform and efficient cooling. This comprehensively improves the extrusion and cooling quality of rice noodle products, shortens the production cycle, increases production efficiency, and achieves an optimal balance between production efficiency and cost.
