Description
Technical Field
[0001] This invention relates to the technical field of rice noodle extrusion processing, and specifically to a uniform discharge device for rice noodle production. Background Technology
[0002] Rice noodles are made from rice that has undergone multiple washing and soaking processes, followed by grinding into a paste, shaping, and high-temperature steaming. The shaping process primarily utilizes an extrusion machine; therefore, the rice noodle extrusion machine is the core equipment in an automated rice noodle production line.
[0003] Patent document CN116420904A discloses a rice noodle wet forming machine, including a rice noodle forming mold, a buffer chamber, an extrusion mold, a transmission support base, a coupling, a reducer, a motor, and a steam pack. The steam pack contains a cylinder, and an extrusion screw is rotatably mounted inside the cylinder. The end of the cylinder is connected to the transmission support base, and the end of the transmission support base is rotatably connected to the coupling. One end of the coupling is connected to the output end of the reducer, and the input end of the reducer is connected to the output end of the motor. A fixed cylinder is fixedly connected to the end of the steam pack away from the transmission support base via a connecting flange. The lower end of the fixed cylinder is fixedly connected to the buffer chamber, and the lower end of the buffer chamber is detachably connected to the rice noodle forming mold. A rotation adjustment seat is located inside the upper end of the fixed cylinder, and the extrusion mold is located inside the connecting flange. Power is provided by a speed reducer and directly connected to the drive shaft via a coupling. The drive shaft then transmits the power to the extrusion screw. Rice slurry enters the space between the extrusion screw and the barrel through the feed hopper and is gradually conveyed forward to form rice noodles under pressure. At the same time, external steam is supplied to the steam generator through the air intake pipeline system. After being extruded by the screw and heated with the assistance of steam, the rice noodles are gradually cooked. The cooked rice noodles are extruded through the extrusion die and enter the buffer chamber. After being further blended in the buffer chamber, the rice noodles are extruded through the vermicelli forming die to complete the vermicelli making process.
[0004] However, this solution also has the following problems. During rice noodle processing, the extrusion screw pushes the rice noodles to the forming mold and applies pressure to them, causing them to be extruded through the mold under pressure. However, during the extrusion process, unstable feeding or uneven screw speed can lead to unstable pressure on the rice noodles at the forming mold. This can cause the rice noodles to be prone to irregular shapes or even breakage due to uneven force during extrusion, affecting the quality of the rice noodles. Summary of the Invention
[0005] This invention provides a uniform discharge device for rice noodle production, aiming to solve the problem in related technologies where unstable pressure during rice noodle extrusion affects the forming quality of rice noodles.
[0006] The present invention provides a uniform discharge device for rice flour production, comprising an extrusion cylinder, wherein a pressure stabilizing component and a control component are disposed within the extrusion cylinder; the pressure stabilizing component includes: an adjusting partition rotatably mounted within the extrusion cylinder, a fixed partition fixedly mounted within the extrusion cylinder, a movable partition axially slidably mounted within the extrusion cylinder, and an elastic telescopic sleeve located between and connecting the movable partition and the fixed partition; the adjusting partition and the fixed partition abut against the side of the movable partition away from the movable partition; the adjusting partition is provided with an adjusting port; both the fixed partition and the movable partition are provided with connecting ports communicating with both ends of the elastic telescopic sleeve; the side of the movable partition away from the fixed partition and the inner wall of the extrusion cylinder form a pressure stabilizing zone; the control component connects the movable partition and the adjusting partition; the movable partition moves with the pressure changes within the pressure stabilizing zone, and simultaneously the control component drives the adjusting partition to rotate, thereby adjusting the size of the overlapping area between the adjusting port and the connecting port to control the feeding speed.
[0007] Its effect lies in the fact that, by setting up a movable baffle, the material sequentially passes through the adjustment port and the elastic telescopic sleeve into the pressure stabilizing zone. When the pressure in the pressure stabilizing zone changes, the movable baffle can move to adjust the pressure in the pressure stabilizing zone. Specifically, the material moves inside the extrusion cylinder, passes through the adjustment port and the connecting port into the pressure stabilizing zone, and is then extruded. When the pressure in the pressure stabilizing zone changes due to uneven feeding or other reasons, the movable baffle will move accordingly. That is, when the pressure in the pressure stabilizing zone increases, the movable baffle moves away from the pressure stabilizing zone, and vice versa. At the same time, the movable baffle drives the adjustment baffle to rotate through the control component, adjusting the material feeding speed so that the pressure in the pressure stabilizing zone fluctuates within a specified range, so as to extrude the material evenly and improve the forming quality of rice noodles.
[0008] Preferably, the control assembly includes: a control collar connected to the outside of the adjusting partition, a control linkage connected to the movable partition, and a control slider disposed on the control linkage. A control groove is formed on the control collar around its rotation axis. One end of the control groove is inclined toward the movable partition. The control slider slides in cooperation with the control groove. When the movable partition moves, it drives the control slider to engage with different positions in the control groove, thereby driving the control collar and the adjusting partition to rotate.
[0009] Its effect is that when the movable partition moves, it drives the control linkage to move, the control linkage to move, the control slider to move, the direction of movement of the control slider is fixed, and when it moves, it cooperates with different positions in the control groove to drive the control collar to rotate, the rotation of the control collar to drive the adjustment partition to rotate, thereby adjusting the size of the overlapping area between the adjustment port and the connecting port to adjust the feeding speed.
[0010] Preferably, the outer diameters of the adjusting partition, the fixed partition, and the movable partition are all adapted to the inner diameter of the extrusion cylinder. An installation groove is provided on the inner wall of the extrusion cylinder, and the control collar is set in the installation groove. The control linkage is connected to the side of the movable partition near the fixed partition.
[0011] The effect is that by setting an installation groove on the inner wall of the extrusion cylinder to place the control collar, the stability of the control collar during rotation is improved.
[0012] Preferably, the control collar is sleeved on the outside of the fixed partition, and a clearance groove is provided on the control collar. A fixing rod is provided on the side of the fixed partition. The fixing rod passes through the clearance groove and is fixedly connected to the inner wall of the mounting groove. When the control collar rotates, the control collar rotates relative to the fixing rod through the clearance groove.
[0013] Its effect is that the fixed partition is fixedly connected to the extrusion cylinder through the fixed rod. When the control collar rotates, the fixed rod can move relative to the control collar in the relief groove, reducing the phenomenon of the fixed rod interfering with the rotation of the control collar.
[0014] Preferably, the end of the extrusion cylinder is provided with a forming component, which includes a connecting pipe, an intermediate pipe, and an extrusion pipe. One end of the connecting pipe is connected to the pressure stabilizing zone inside the extrusion cylinder, and the other end is connected to the middle position of the intermediate pipe. Both ends of the intermediate pipe are connected to the extrusion pipe, and the side of the extrusion pipe is provided with a discharge hole along its length.
[0015] Its effect is that the material enters the extrusion tube through the connecting pipe and the intermediate pipe, and is finally extruded through the extrusion tube.
[0016] Preferably, an extrusion plate is provided inside the extrusion tube, and extrusion holes are provided on the side of the extrusion plate. Multiple extrusion holes are arranged along the length of the discharge hole. The extrusion plate is set in an arc around the center of the extrusion tube. Two sets of extrusion holes are arranged around the center line of the extrusion tube. The diameters of the two sets of extrusion holes are set to different sizes. After the material enters the extrusion tube, it is extruded through the extrusion holes and the discharge hole in sequence.
[0017] The effect is that by setting two sets of extrusion holes of different specifications on the extrusion plate, the extrusion plate can be rotated according to the specifications of the rice noodles during the extrusion process, so that the corresponding extrusion holes correspond to the discharge holes, so as to process rice noodles of specified specifications according to needs.
[0018] Preferably, the extrusion tube has openings at both ends, and the extrusion plate has sealing plates at both ends. The sealing plates are located at the openings at both ends of the extrusion tube. The length of the extrusion plate is the same as the length of the extrusion tube. The extrusion tube has fixing clamps at both ends. The inner side of the fixing clamps abuts against the sealing plates and the extrusion tube to fix the extrusion plate.
[0019] The effect is that, after adjusting the position of the extrusion plate, the fixing clamp is placed at the end of the extrusion tube to fix the sealing plate, and at the same time, the sealing plate seals both ends of the extrusion tube. The extrusion plate is fixed inside the extrusion tube by the fixing clamp, so that the extrusion plate can be removed for cleaning, and the position of the extrusion plate can be easily adjusted.
[0020] Preferably, the extrusion cylinder is provided with a feeding port, and the extrusion screw is provided inside the extrusion cylinder. The extrusion screw is located on the side of the adjusting partition away from the fixed partition, and the extrusion screw is located below the feeding port.
[0021] Its effect is that by setting up a feeding port and an extrusion screw, the material is fed into the extrusion cylinder. At the same time, the rotation of the extrusion screw drives the material to move closer to the pressure stabilizing zone, and pressure is applied to the material to extrude it.
[0022] Preferably, the elastic telescopic sleeve includes: a sliding sleeve connected to a fixed partition, a sliding ring connected to a movable partition, and an elastic element. A sliding groove is provided in the side wall of the sliding sleeve, the sliding ring is slidably assembled in the sliding groove, and the elastic element is disposed in the sliding groove and connected to the sliding ring.
[0023] Its effect is that when the movable partition moves, the slip ring moves inside the sliding sleeve, compressing the elastic element at the same time. The slip ring and the sliding sleeve always maintain a cooperative state, so that the material can pass stably between the fixed partition and the movable partition, improving the stability of material conveying.
[0024] Preferably, multiple sets of adjustment ports, connecting ports, and elastic telescopic sleeves are provided around the center line of the extrusion cylinder.
[0025] Its effect is that by setting up multiple sets of adjustment ports, connecting ports, and elastic expansion sleeves, the material can be evenly introduced into the pressure stabilization zone, and the pressure stabilization zone can be evenly stressed.
[0026] Beneficial effects:
[0027] 1. This invention, by setting up movable partitions and adjustable partitions, allows the movable partitions to move under the action of elastic telescopic sleeves to adjust the size of the pressure stabilizing zone when the amount of material fed changes. At the same time, the adjustable partitions rotate to adjust the speed at which the material enters the pressure stabilizing zone, so that the pressure in the pressure stabilizing zone is maintained within a certain range, resulting in uniform material discharge and improved rice noodle forming quality.
[0028] 2. An extrusion plate is installed inside the extrusion tube, and two sets of extrusion holes with different diameters are set on the extrusion plate. By rotating the extrusion plate, the extrusion holes of different specifications can be adjusted to correspond with the discharge holes on the extrusion tube, so that the diameter of the extruded rice noodles corresponds to the diameter of the extrusion holes, thereby realizing the processing of rice noodles of different specifications to meet different processing needs.

[0040] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.
[0041] like Figures 1 to 9As shown, the uniform discharge device for rice noodle production of the present invention includes an extrusion cylinder 1 and a forming component 6 located at the end of the extrusion cylinder 1. A feeding port 12 is provided on the extrusion cylinder 1, through which material is fed into the extrusion cylinder 1. An extrusion screw 13 is rotatably disposed inside the extrusion cylinder 1. The power source for the extrusion screw 13 is a motor, i.e., the output end of the motor is connected to the extrusion screw 13. In this embodiment, the extrusion cylinder 1 is placed horizontally, the feeding port 12 is located above the extrusion cylinder 1, and the extrusion screw 13 is located below the feeding port 12. During rice noodle processing, material is added into the extrusion cylinder 1 through the feeding port 12. Subsequently, the extrusion screw 13 drives the material to move closer to the forming component 6, and then the forming component 6 extrudes the material from the extrusion cylinder 1, thus forming the rice noodles.
[0042] A pressure stabilizing component 2 and a control component 3 are installed inside the extrusion cylinder 1. A pressure stabilizing zone 11 is also installed inside the extrusion cylinder 1, located at one end of the extrusion cylinder 1 near the forming component 6. The end of the extrusion screw 13 corresponds to the pressure stabilizing zone 11. The pressure stabilizing component 2 controls the material pressure within the pressure stabilizing zone 11, and the control component 3 controls the speed at which the material enters the pressure stabilizing zone 11. During processing, the extrusion screw 13 moves the material into the pressure stabilizing zone 11, and then through the pressure stabilizing zone 11 into the forming component 6, extruding the rice noodles. During the extrusion of the rice noodles, the pressure stabilizing component 2 and the control component 3 work together to maintain the pressure of the material within the pressure stabilizing zone 11 within a specified range, preventing large fluctuations in the pressure on the material during extrusion, thereby improving the stability of the material during extrusion, ensuring uniform stress, and improving the forming quality of the rice noodles.
[0043] Reference Figure 1 , Figure 2 The molding component 6 includes: a connecting pipe 61, an intermediate pipe 62, and an extrusion pipe 63. The connecting pipe 61 is disposed at the output end of the extrusion cylinder 1. The intermediate pipe 62 is disposed between the connecting pipe 61 and the extrusion pipe 63 and connects the two. The connecting pipe 61 is connected to the interior of the extrusion cylinder 1. One end of the connecting pipe 61 away from the extrusion cylinder 1 is connected to the middle position of the intermediate pipe 62. Both ends of the intermediate pipe 62 are bent in the direction away from the connecting pipe 61. Both ends of the intermediate pipe 62 are connected to the side of the extrusion pipe 63. The distance between the two ends of the intermediate pipe 62 is the same as the distance between one end of the intermediate pipe 62 and the end of the extrusion pipe 63, so that the material can enter the extrusion pipe 63 evenly through the intermediate pipe 62.
[0044] Reference Figure 2 , Figure 3 A discharge hole 631 is provided on the side of the extrusion tube 63, and the discharge hole 631 is arranged along the length direction of the extrusion tube 63. An extrusion plate 7 is provided inside the extrusion tube 63, and the extrusion plate 7 is arranged along the length direction of the extrusion tube 63. Multiple extrusion holes 71 are arranged on the side of the extrusion plate 7, and the extrusion holes 71 correspond to the discharge holes 631.
[0045] The extrusion screw 13 drives the material to move inside the extrusion cylinder 1 and bring it close to the connecting pipe 61. Then, it enters the intermediate pipe 62 through the connecting pipe 61, and then enters the extrusion pipe 63 through the intermediate pipe 62. Finally, it is extruded through the extrusion hole 71. Under the action of the extrusion hole 71, the material is made into a circular strip, which shapes the rice noodles.
[0046] Reference Figure 2 , Figure 3 The extrusion plate 7 has two sets of extrusion holes 71, which are arranged in parallel and spaced apart, and the diameters of the two sets of extrusion holes 71 are different. During processing, the different extrusion holes 71 can be adjusted to correspond with the discharge hole 631 to obtain rice noodles of different diameters. In other embodiments, multiple sets of extrusion holes 71 with different diameters can be set according to actual processing needs. When multiple sets of extrusion holes 71 are set, the straight lines of each set of extrusion holes 71 are arranged parallel to each other, and the corresponding diameter of the extrusion hole 71 is adjusted to correspond with the discharge hole 631 according to processing needs.
[0047] Reference Figure 3 , Figure 4 To facilitate adjustment of the different extrusion holes 71 corresponding to the discharge hole 631, the extrusion plate 7 is arc-shaped around the center line of the extrusion tube 63, and the outer side of the extrusion plate 7 abuts against the inner wall of the extrusion tube 63. Openings are provided at both ends of the extrusion tube 63, and sealing plates 8 are provided at both ends of the extrusion plate 7, positioned at the openings at both ends of the extrusion tube 63. Fixing clamps 9 are provided at both ends of the extrusion tube 63, sleeved on the outside of the extrusion tube 63, with the inner side of the fixing clamps abutting against the side of the sealing plate 8 to fix the sealing plate 8.
[0048] When the position of the extrusion plate 7 needs to be adjusted, first remove the fixing clamp 9, then rotate the sealing plate 8 to align different positions on the extrusion plate 7 with the discharge hole 631. Then, fix the sealing plate 8 and the extrusion plate 7 with the fixing clamp 9. Additionally, the outer diameter of the sealing plate 8 is matched to the opening at the end of the extrusion tube 63, meaning the sealing plate 8 can be inserted into the extrusion tube 63 through the opening. This allows the extrusion plate 7 to be removed from the extrusion tube 63 for cleaning operations such as the extrusion hole 71. Furthermore, a rubber gasket is installed inside the fixing clamp 9. The fixing clamp 9 abuts against the ends of the sealing plate 8 and the extrusion tube 63 through the rubber gasket. Even when the diameter of the sealing plate 8 is smaller than the opening diameter of the extrusion tube 63, the rubber gasket can still abut against the side of the sealing plate 8, thereby increasing the contact area between the rubber gasket and the sealing plate 8, thus fixing the sealing plate 8 and ensuring a tight seal between the sealing plate 8 and the end of the extrusion tube 63, reducing material leakage. Two fixing clamps 9 are provided at both ends of the extrusion tube 63 to fix the two ends of the extrusion plate 7 respectively.
[0049] Reference Figure 5 , Figure 6 , Figure 7 , Figure 9 The pressure stabilizing assembly 2 includes: an adjusting partition 21, a fixed partition 22, a movable partition 23, and an elastic telescopic sleeve 24. The adjusting partition 21, fixed partition 22, and movable partition 23 are arranged sequentially along the material conveying direction, i.e., the fixed partition 22 is located between the adjusting partition 21 and the movable partition 23. The movable partition 23 is located on the side of the fixed partition 22 away from the extrusion screw 13. The adjusting partition 21 abuts against the side of the fixed partition 22 away from the movable partition 23. The adjusting partition 21, fixed partition 22, and movable partition 23 are all coaxially arranged with the center line of the extrusion cylinder 1. An adjusting port 211 is provided on the adjusting partition 21, which is arranged through the adjusting partition 21 along the material conveying direction. A connecting port 221 is provided through the fixed partition 22 and the movable partition 23. The line connecting the two connecting ports 221 on the fixed partition 22 and the movable partition 23 is parallel to the center line of the extrusion cylinder 1. The elastic telescopic sleeve 24 is a flexible tubular structure. The elastic telescopic sleeve 24 is disposed between the fixed partition 22 and the movable partition 23, and both ends of the elastic telescopic sleeve 24 are connected to the connecting port 221 respectively.
[0050] Reference Figure 5 The side wall of the movable partition 23 is slidably engaged with the inner wall of the extrusion cylinder 1, that is, the movable partition 23 can slide inside the extrusion cylinder 1. The fixed partition 22 is fixedly installed inside the extrusion cylinder 1. The side of the movable partition 23 away from the fixed partition 22 and the inner wall of the extrusion cylinder 1 enclose the pressure stabilizing zone 11.
[0051] Initially, the regulating port 211 corresponds to the connecting port 221. After the material is added into the extrusion cylinder 1, the extrusion screw 13 drives the material conveying. The material passes through the regulating port 211, the connecting port 221, and the elastic telescopic sleeve 24 into the pressure stabilizing zone 11 and is finally extruded. During the extrusion process, the material in the pressure stabilizing zone 11 bears pressure. When the feeding is unstable or the rotation of the extrusion screw 13 fluctuates, the pressure in the pressure stabilizing zone 11 will change. At this time, the elastic telescopic sleeve 24 extends and retracts, causing the movable partition 23 to move to adaptively adjust the size of the pressure stabilizing zone 11, thereby making the pressure borne by the material in the pressure stabilizing zone 11 fluctuate within a small range to improve the stability of the material during extrusion.
[0052] Reference Figure 6 , Figure 9The elastic telescopic sleeve 24 includes: a sliding sleeve 241, a slip ring 242, and an elastic element 243. Both the sliding sleeve 241 and the slip ring 242 are annular. The sliding sleeve 241 is connected to the fixed partition 22, and the slip ring 242 is connected to the movable partition 23. A groove 244 is provided in the side wall of the sliding sleeve 241. The end of the slip ring 242 extends into the groove 244, and the slip ring 242 slides in conjunction with the sliding sleeve 241. The sliding direction of the slip ring 242 in the sliding sleeve 241 is parallel to the center line of the extrusion cylinder 1. The elastic element 243 is a spring. The elastic element 243 is provided in the groove 244 and is connected to the slip ring 242. The elastic element 243 is used to drive the slip ring 242 to slide in a direction away from the fixed partition 22.
[0053] Material enters the pressure stabilizing zone 11 through the sliding sleeve 241 and slip ring 242. When the movable partition 23 moves, the sliding sleeve 241, connected to the fixed partition 22, remains stationary, while the slip ring 242 moves relative to the sliding sleeve 241, simultaneously compressing the elastic element 243. That is, when a sudden increase in the feed rate leads to an increase in pressure in the pressure stabilizing zone 11, the movable partition 23 moves closer to the fixed partition 22, compressing the elastic element 243 and increasing the space of the pressure stabilizing zone 11. Conversely, when a sudden decrease in the feed rate leads to a decrease in pressure in the pressure stabilizing zone 11, the elastic element 243 drives the movable partition 23 to move closer to the pressure stabilizing zone 11, reducing the space of the pressure stabilizing zone 11. This allows the pressure stabilizing zone 11 to be maintained within a certain pressure range.
[0054] Reference Figure 6 , Figure 9 Multiple sets of regulating ports 211, connecting ports 221, and elastic telescopic sleeves 24 are arranged around the center line of the extrusion cylinder 1. Through multiple sets of regulating ports 211 and connecting ports 221, the material can be evenly entered into the pressure stabilizing zone 11, so that the pressure in each part of the pressure stabilizing zone 11 is evenly distributed, thereby improving the extrusion quality of rice noodles.
[0055] The adjusting baffle 21 is rotatably mounted inside the extrusion cylinder 1. The rotation axis of the adjusting baffle 21 is on the same straight line as the center line of the extrusion cylinder 1. The control component 3 connects the adjusting baffle 21 and the movable baffle 23. When the movable baffle 23 moves inside the extrusion cylinder 1, it drives the adjusting baffle 21 to rotate through the control component 3. Initially, the adjusting port 211 corresponds to the connecting port 221. When the pressure fluctuates in the pressure stabilizing zone 11, the movable baffle 23 moves accordingly. When the movable baffle 23 moves, it drives the adjusting baffle 21 to rotate through the control component 3, thereby adjusting the size of the overlapping area between the adjusting port 211 and the connecting port 221, and thus controlling the speed at which the material enters the pressure stabilizing zone 11. When the pressure in the stabilizing zone 11 increases, the movable partition 23 moves closer to the fixed partition 22, increasing the space in the stabilizing zone 11. Simultaneously, the movable partition 23, through the control component 3, drives the adjusting partition 21 to rotate, which in turn drives the adjusting port 211 to rotate, reducing the overlap between the adjusting port 211 and the connecting port 221, thereby decreasing the material feeding speed. When the pressure in the stabilizing zone 11 decreases, the movable partition 23 moves away from the fixed partition 22, decreasing the space in the stabilizing zone 11. Simultaneously, the movable partition 23, through the control component 3, drives the adjusting partition 21 to rotate, which in turn drives the adjusting port 211 to rotate, increasing the overlap between the adjusting port 211 and the connecting port 221, thereby increasing the material feeding speed.
[0056] Reference Figure 7 , Figure 9 The control assembly 3 includes a control collar 31, a control connecting rod 32, and a control slider 33. The control collar 31 is disposed outside the adjusting partition 21, and its inner side is connected to the adjusting partition 21. The control collar 31 and the adjusting partition 21 are coaxially connected. The control connecting rod 32 is connected to the movable partition 23. The control slider 33 is disposed on the control connecting rod 32. A control groove 311 is formed on the control collar 31. The control groove 311 is arc-shaped around the rotation axis of the control collar 31. One end of the control groove 311 is inclined along the center line of the extrusion cylinder 1. The control connecting rod 32 is located inside the control collar 31 and extends towards the adjusting partition 21. The control slider 33 is slidably assembled in the control groove 311.
[0057] When the movable partition 23 moves, the movable partition 23 drives the control slider 33 to move through the control linkage 32. The control slider 33 moves to different positions in the control groove 311, causing the control collar 31 to rotate, which in turn causes the adjusting partition 21 to rotate, so as to adjust the position of the adjusting partition 21.
[0058] Reference Figure 5An installation groove 4 is provided on the inner wall of the extrusion cylinder 1. A control collar 31 is disposed in the installation groove 4 and slides within it. The outer diameters of the adjusting partition 21, the fixed partition 22, and the movable partition 23 match the inner diameter of the extrusion cylinder 1. A control linkage 32 is disposed on the side of the movable partition 23 near the fixed partition 22. This ensures a tight fit between the components when the adjusting partition 21 drives the control collar 31 to rotate, reducing material entry between the components and improving overall stability.
[0059] Reference Figure 9 The control collar 31 extends from the end opposite to the adjusting partition 21 toward the movable partition 23, and passes through the fixed partition 22, meaning the control collar 31 is fitted onto the outside of the fixed partition 22. A control groove 311 is located on the side of the fixed partition 22 closest to the movable partition 23. A clearance groove 312 is formed on the control collar 31, and the clearance groove 312 is arc-shaped around the center of the extrusion cylinder 1. A fixing rod 5 is provided on the fixed partition 22, passing through the clearance groove 312 and fixedly connected to the inner wall of the mounting groove 4, so that the fixed partition 22 is fixed inside the extrusion cylinder 1. Simultaneously, the control collar 31 can rotate outside the fixed partition 22 through the clearance groove 312, preventing the fixing rod 5 from interfering with the rotation of the control collar 31.
[0060] Reference Figure 9 The inner side of the control collar 31 abuts against the outer side of the fixed partition 22, and the thickness of the fixed partition 22 is greater than the width of the clearance groove 312. That is, when the control collar 31 and the fixed partition 22 are engaged, the side of the fixed partition 22 blocks the clearance groove 312. When the control collar 31 rotates, the clearance groove 312 is always in a blocked state, reducing the phenomenon of material entering the clearance groove 312, so that the control collar 31 can rotate stably. At the same time, when the material is conveyed, it passes through the elastic telescopic sleeve 24 between the fixed partition 22 and the movable partition 23, avoiding the phenomenon of material entering the control groove 311, so as to ensure the stability of the engagement between the control slider 33 and the control groove 311.
[0061] The implementation principle of this invention is as follows: according to the processing requirements of rice noodles, the extrusion plate 7 is rotated to adjust the corresponding extrusion hole 71 to correspond with the discharge hole 631. Then, the fixing clamp 9 is used in conjunction with the sealing plate 8 to fix the extrusion plate 7 and at the same time, the two ends of the extrusion tube 63 are sealed.
[0062] Material is added into extrusion cylinder 1 through feeding port 12. Then, extrusion screw 13 rotates to convey the material. The material enters pressure stabilizing zone 11 through regulating port 211, connecting port 221 and elastic telescopic sleeve 24. As the material in pressure stabilizing zone 11 gradually increases and becomes full, the pressure in pressure stabilizing zone 11 gradually increases. At the same time, movable partition 23 moves and elastic telescopic sleeve 24 is compressed. After the pressure in pressure stabilizing zone 11 reaches the specified value, the material is extruded through extrusion hole 71.
[0063] When the pressure in the stabilizing zone 11 decreases, the movable partition 23 moves closer to the stabilizing zone 11. Simultaneously, the control linkage 32 drives the control slider 33 to move, and the control collar 31 drives the adjusting partition 21 to rotate, controlling the size of the overlapping area between the adjusting port 211 and the connecting port 221. When the pressure in the stabilizing zone 11 increases, both the movable partition 23 and the adjusting partition 21 move or rotate in opposite directions. The movement of the movable partition 23 adjusts the pressure of the material in the stabilizing zone 11, while the position of the adjusting partition 21 controls the feeding speed, so that the pressure on the material in the stabilizing zone 11 fluctuates within a specified range, ensuring uniform extrusion of the material and improving the forming quality of the rice noodles.

Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
