Description

Technical Field

[0001] This utility model relates to the field of food processing equipment technology, specifically an automatic noodle cutter. Background Technology

[0002] Currently, automatic noodle cutters have been applied in the food processing industry to improve production efficiency and product quality. However, existing automatic noodle cutters still face some challenges in practical applications, especially in achieving efficient continuous cutting, ensuring cutting quality, preventing noodle sticking during conveying and cutting, and cleaning and maintaining the cutting tools.

[0003] Chinese utility model patent CN218018806U discloses a fully automatic vermicelli cutting machine. This patent uses a motor-driven conveyor belt to transport vermicelli and a hydraulic cylinder to drive a push plate with a cutter for cutting. At the same time, a pressure plate mechanism is provided to press the vermicelli to prevent it from curling up during cutting, thus ensuring the stability of cutting to a certain extent.

[0004] Chinese utility model patent CN206909618U discloses an automatic hanging and cutting machine for rice noodles. This patent discloses a continuous production equipment that integrates hanging, lifting, guiding, cutting and drying of rice noodles. It realizes automatic hanging, lifting and conveying of rice noodles by using horizontal, vertical and horizontal conveyor chains with rod plates. It uses a fixed knife seat and a movable cutter (horizontal reciprocating motion) to cut the rice noodles. It has a high degree of automation and realizes continuous operation of multiple processes.

[0005] The above designs, through their respective mechanical structures and automated control schemes, have achieved automatic cutting, conveying, and a certain degree of post-processing of vermicelli, making beneficial explorations in improving production efficiency and reducing manual labor intensity. However, there are still certain limitations. For example, there is still room for improvement and optimization in pursuing ultimate cutting efficiency (such as high-speed synchronous flying shears), improving cutting quality (such as smooth and undamaged cuts without adhesion), more effectively solving the adhesion problem of vermicelli (especially high-humidity, high-viscosity vermicelli) during the entire conveying and cutting process, and achieving efficient self-cleaning and lubrication of cutting tools to ensure long-term stable and efficient operation. For instance, traditional cutting methods may not be able to completely avoid the squeezing or pulling of vermicelli during the cutting moment, resulting in uneven cuts or vermicelli deformation; adhesion between vermicelli and conveyor belts or guide components during conveying can easily cause vermicelli breakage and accumulation, affecting production continuity and yield; vermicelli residue easily adheres to cutting tools, requiring frequent shutdowns for cleaning, which reduces production efficiency and may also pose hygiene hazards.

[0006] Therefore, there is an urgent need to develop a new type of automatic noodle cutter that can integrate more advanced conveying and anti-sticking technology, efficient and precise cutting technology that minimizes damage to the noodles (such as synchronous flying shear technology with high-frequency vibration), and self-cleaning and lubrication technology for the cutting blades. This will ensure high production efficiency while significantly improving cutting quality and yield, reducing equipment maintenance difficulty and operating costs, and better meeting the modern food processing industry's demand for high-quality, high-efficiency, and high-stability production. Summary of the Invention

[0007] The purpose of this invention is to overcome the shortcomings of the existing technology and propose an automatic powder cutter to solve the above-mentioned problems.

[0008] The purpose of this utility model is achieved through the following technical solution: An automatic powder cutter includes a conveyor group one, a conveyor group two, and a conveyor group three arranged in sequence. A cutting mechanism is provided between conveyor group one and conveyor group two, and a hanging rod is provided between conveyor group two and conveyor group three. Each of conveyor group one, conveyor group two, and conveyor group three includes multiple conveyor belt supports. A conveyor belt is attached to the outer end of each conveyor belt support. An air groove is provided at the top of each conveyor belt support. Multiple through holes are provided on the conveyor belt, and the through holes communicate with the air grooves on the conveyor belt supports. The same air pipe is fixedly connected to the multiple conveyor belt supports. One end is connected to an external air supply system. The outer ends of conveying group one, conveying group two, and conveying group three are fixedly connected to the same base. The cutting mechanism includes an outer tube. A cutting plate symmetrically arranged on the left and right sides is slidably connected inside the outer tube. Multiple cutting blades are fixedly connected to the top of the cutting plate. Piezoelectric stacks are fixedly connected to both ends of the cutting plate. One of the two piezoelectric stacks corresponding to the cutting plate is fixedly connected to a cylinder at the end away from the cutting plate. The outer end of the outer tube passes through the base, and a gear one is fixedly connected to the passing part. Gear two is meshed with the outer end of gear one. A water tank is fixedly connected to the bottom of the base at the position corresponding to the outer tube.

[0009] Both ends of the conveyor belt support are rotatably connected to rollers, and the air pipe is located at the position of the air trough and is connected to the air trough through air holes.

[0010] The outer end of the roller is positioned to contact the inner wall of the conveyor belt, and multiple through holes on the conveyor belt are evenly distributed around the outer end of the conveyor belt.

[0011] Multiple rollers located at the same end of the conveyor belt support are fixedly connected by the same shaft.

[0012] Multiple rotating shafts are rotatably connected to the base, and the upper and lower supports are fixedly connected to the top and bottom of the base and the corresponding position of the hanging rod, respectively.

[0013] The hanging rod can slide within the upper and lower supports, and the hanging rod slides within the upper and lower supports via an external lifting device.

[0014] The piezoelectric stacks are all made of piezoelectric materials, and the cylinders are double-acting cylinders.

[0015] A motor is fixedly connected to the base at the position corresponding to gear two, and the motor's power shaft is fixedly connected to gear two.

[0016] The tank is filled with water, the cylinder is fixedly connected to the outer tube, and the sliding direction of the cutting plate coincides with the axis of the outer tube.

[0017] A flow divider plate is provided at one end of conveyor group one, away from conveyor group two, and multiple flow divider slots are opened at the top of the flow divider plate. The number of flow divider slots is equal to the number of conveyor belts.

[0018] The beneficial effects of this utility model are:

[0019] 1. By tightly integrating and automating processes such as orderly introduction of vermicelli, pneumatically assisted non-sticking conveying, high-speed synchronous flying shear cutting, and automatic lifting and hanging rods, a continuous and automated production process from wet vermicelli to a suspended state is achieved, greatly improving overall production efficiency and reducing reliance on manual labor. The diverting plate at the front end ensures that multiple strands of vermicelli can enter their respective conveying channels evenly and orderly, avoiding initial confusion, bridging, or breakage. The pneumatically assisted design in the conveying system effectively prevents fresh, wet vermicelli from sticking to the conveyor belt by forming an air cushion effect on the conveyor belt surface, ensuring smooth conveying and significantly reducing the stretching deformation and breakage of vermicelli, thereby improving the appearance and internal quality of the finished product. The high-frequency vibration cutting technology adopted by the cutting mechanism causes the cutting blade to generate high-frequency micro-vibration at the moment of cutting, greatly reducing cutting resistance and achieving a very flat and smooth cut, avoiding burrs, compression, or tearing, maintaining the perfect shape of the vermicelli cut, and effectively preventing vermicelli from adhering to the blade.

[0020] 2. The design of the synchronous flying shear mechanism enables the cutting device to rotate synchronously with the conveying speed of the vermicelli and perform cutting, realizing the cutting while the vermicelli is continuously conveyed without stopping. This avoids the start-stop impact and time loss caused by traditional intermittent cutting. The cutting plate is driven by a double-acting cylinder, which is fast and reliable. Combined with its precise linear guidance in the outer tube of the cutting mechanism, it ensures the stability of the cutting action and the consistency of the cutting length.

[0021] 3. During the rotation process, the cutting blade periodically comes into contact with the water in the water tank, which plays a dual role of immediate lubrication and cleaning. Lubrication reduces the adhesion of the powder during cutting, making the cutting smoother; while the water flow, combined with the high-frequency vibration of the blade itself, can effectively remove the tiny powder particles that adhere to the blade after cutting, realizing the self-cleaning of the blade. This not only keeps the blade sharp and extends its service life, but also ensures the hygiene standards of the production process.

[0022] 4. The cut vermicelli segments can be precisely positioned directly below the hanging rod by the conveying system. Then, the hanging rod is automatically lifted and suspended by the external lifting equipment. This process is highly automated, reduces the chance of direct human contact with the vermicelli, significantly improves the efficiency of the hanging rod and the hygiene level of the operation, and provides convenience for subsequent drying or packaging processes.

[0023] 5. All conveying groups, cutting mechanisms, and hanging rod mechanisms are securely installed on the same base, ensuring the overall rigidity of the equipment and the relative positional accuracy between components, providing a foundation for high-speed and stable operation. The conveyor belt is supported and driven by a reasonably structured conveyor belt bracket and rollers, ensuring smooth conveying. Attached Figure Description

[0037] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.

[0038] It should be noted that the directional concepts of "left", "right", "up", "down", "front", "back", "inner", and "outer" in the following scheme are all relative directions, and will not be listed one by one here.

[0039] Example 1

[0040] like Figures 1 to 11 As shown, this embodiment provides an automatic noodle cutter, and particularly relates to its conveying system, noodle introduction, and pneumatically assisted anti-sticking structure.

[0041] The automatic noodle cutter of this embodiment is characterized by comprising conveyor group 1, conveyor group 2, and conveyor group 3 arranged in sequence. A cutting mechanism is provided between conveyor group 1 and conveyor group 2, and a hanging rod 4 is provided between conveyor group 2 and conveyor group 3. These three conveyor groups together constitute the main conveying path of the noodle from extrusion to the hanging rod.

[0042] Conveying group 1, conveying group 2, and conveying group 3 each include multiple conveyor belt supports 5. Each conveyor belt support 5 has rollers 7 rotatably connected to both ends. Multiple rollers 7 located at the same end of the conveyor belt support 5 are fixedly connected by the same rotating shaft 9. This means that each conveying group can contain multiple parallel conveyor belt paths, driven by a common rotating shaft 9. The outer end of the conveyor belt support 5 is in contact with the conveyor belt 6, and the outer end of the roller 7 is in contact with the inner wall of the conveyor belt 6. The rotation of the roller 7 drives the conveyor belt 6 to move.

[0043] To reduce the sticking of vermicelli during the conveying process, this embodiment features a specially designed pneumatic auxiliary structure. An air groove is provided at the top of the conveyor belt support 5, and multiple through holes are provided on the conveyor belt 6. These through holes are evenly distributed around the outer end of the conveyor belt 6 to ensure uniform airflow. The through holes are connected to the air groove on the conveyor belt support 5. Multiple conveyor belt supports 5 are fixedly connected to the same air pipe 8. This air pipe 8 is located at the position of the air groove and is connected to the air groove through an air hole (not individually numbered, but serving as the connection channel between the air pipe 8 and the air groove). One end of the air pipe 8 is connected to an external air supply system (e.g., an air compressor, not shown).

[0044] In order to achieve orderly introduction of vermicelli, a diverter plate is provided at the end of conveyor group 1 away from conveyor group 2 (i.e., the feeding end). The top of the diverter plate is provided with multiple diverter grooves. The number of diverter grooves is equal to the number of conveyor belts 6, so as to ensure that the vermicelli coming out of the extruder can be distributed one-to-one to each conveyor belt 6.

[0045] The outer ends of conveyor group 1, conveyor group 2 and conveyor group 3 are fixedly connected to the same base 10 by bolts or other fasteners, forming a stable overall structure.

[0046] In addition, as part of the overall equipment, the cutting mechanism includes an outer tube 13, with symmetrically arranged cutting plates 14 slidably connected inside the outer tube 13. Multiple cutting blades 15 are fixedly connected to the top of the cutting plates 14, and piezoelectric stacks 16 are fixedly connected to both ends of the cutting plates 14. One of the two piezoelectric stacks 16 corresponding to the cutting plates 14 is fixedly connected to a cylinder 17 at the end away from the cutting plates 14. The outer end of the outer tube 13 passes through the base 10, and a gear 18 is fixedly connected to the passing part. A gear 2 is meshed with the outer end of the gear 18. A water tank 19 is fixedly connected to the bottom of the base 10 at the position corresponding to the outer tube 13. These components of the cutting mechanism are mainly mentioned as necessary components in the middle of the conveying path in this embodiment, and their detailed working methods will be described in other embodiments.

[0047] Work process

[0048] When the automatic rice noodle cutter is working, firstly, continuous rice noodle strips are extruded through an external rice noodle extruder (not shown). These rice noodle strips are guided to the diversion plate at the front end of the conveyor group 1 of the machine. Since the diversion plate is equipped with a number of diversion grooves equal to the number of conveyor belts 6, the rice noodle strips will fall into the corresponding diversion grooves respectively, and thus be evenly and orderly distributed to the starting end of each parallel-running conveyor belt 6.

[0049] Subsequently, the drive system (e.g., a motor drives the shaft 9 via a chain or gear, not shown) is started, causing the shaft 9 to rotate. The roller 7 fixed on the shaft 9 rotates accordingly and, through contact friction with the inner wall of the conveyor belt 6, drives the conveyor belt 6 forward. The rice noodles then move forward from conveyor group 1 to conveyor group 2 and conveyor group 3, following the movement of the conveyor belt 6.

[0050] Throughout the entire conveying process of the rice noodles, the external air supply system connected to the air pipe 8 continuously supplies air. The airflow passes through the air pipe 8, enters the air holes on the conveyor belt support 5, and is then distributed into the air grooves. Since the air grooves are connected to the through holes on the conveyor belt 6, the airflow will blow upward from the multiple through holes evenly distributed on the conveyor belt 6. These upward airflows form a thin air cushion between the rice noodles and the surface of the conveyor belt 6, or at least significantly reduce the direct contact area and pressure between the rice noodles and the surface of the conveyor belt 6. This air-floating or semi-air-floating state allows the rice noodles, especially fresh rice noodles with high moisture content and easy sticking, to move smoothly on the conveyor belt 6 without sticking tightly to the belt surface.

[0051] After the rice noodles run smoothly on conveyor group 1, they will pass through the cutting mechanism area between conveyor group 1 and conveyor group 2 (at this time, the cutting mechanism may not have been activated or may have completed the cutting of the previous batch). Then, they will enter conveyor group 2 for further conveying. Next, the rice noodles will be conveyed from conveyor group 2 to conveyor group 3, and finally arrive at the hanging rod 4 area between conveyor group 2 and conveyor group 3, preparing for subsequent cutting (if cutting is done at this stage) and hanging for drying. This embodiment mainly focuses on how the rice noodles are effectively and non-sticky conveyed to these functional areas.

[0052] By sequentially setting up conveyor group 1, conveyor group 2, and conveyor group 3, and with the introduction of the diversion plate, the automated and continuous conveying of rice noodles or rice vermicelli is realized, laying the foundation for subsequent processes such as cutting and hanging, and improving overall production efficiency.

[0053] The diverter plate and its diverter groove, located at the front end of conveyor group 1, can effectively separate and guide the multiple strands of rice noodles or rice vermicelli extruded from the extruder, ensuring that each strand of vermicelli can accurately enter its respective conveyor belt channel 6, avoiding the vermicelli from merging, tangling or piling up, and ensuring the orderly production.

[0054] The pneumatic auxiliary system, consisting of the air grooves on the conveyor belt support 5, the through holes on the conveyor belt 6, and the air pipes 8 connected to the external air supply system, blows air out from the through holes during the conveying process, forming an air cushion between the rice noodles or rice vermicelli and the surface of the conveyor belt 6. This effectively reduces or eliminates the sticking of fresh rice noodles or rice vermicelli to the conveyor belt 6. This not only ensures the smoothness of the conveying and prevents stretching deformation, breakage, or conveyor belt blockage caused by sticking, but also improves the appearance and integrity of the final product, while also reducing the difficulty of cleaning the conveyor belt 6.

[0055] Each conveyor group is fixed to the same base 10, which ensures the overall rigidity and operational stability of the equipment. The conveyor belt bracket 5 supports the conveyor belt 6 at both ends through rollers 7, and the rollers 7 on the same side are driven by a common shaft 9, which ensures that multiple conveyor belts 6 operate synchronously and smoothly, and improves the reliability of conveying.

[0056] Example 2

[0057] like Figures 1 to 11 As shown, this embodiment, based on the overall structure of embodiment 1, further describes in detail the specific structure, precision working method and beneficial effects of the cutting mechanism and hanging rod mechanism of the automatic powder cutter. The machine also includes conveyor group 1, conveyor group 2 and conveyor group 3 arranged in sequence. The cutting mechanism is set between conveyor group 1 and conveyor group 2, and the hanging rod 4 is set between conveyor group 2 and conveyor group 3. The conveyor belt support 5, conveyor belt 6 and its pneumatic auxiliary structure (air groove, through hole, air pipe 8) and diverter plate of these conveyor groups are all installed on the base 10 as in embodiment 1.

[0058] As in Embodiment 1, multiple rotating shafts 9 used to drive the conveyor belt 6 are rotatably connected to the base 10. In this embodiment, in order to realize the automatic hanging of vermicelli, the base 10 has an upper support 11 and a lower support 12 firmly fixedly connected to its top and bottom ends respectively at the position corresponding to the hanging rod 4. These two supports 11 and 12 are used to guide and support the hanging rod 4. The hanging rod 4 is designed as a slender rod structure, and its two ends or specific parts can slide smoothly up and down in the guide rail or hole formed by the upper support 11 and the lower support 12. The hanging rod 4 is driven by an external lifting device (such as a cylinder, a motor-driven screw slide, etc., the specific type is not clearly shown in the figure) to realize the controlled lifting movement between the upper support 11 and the lower support 12.

[0059] The cutting mechanism is one of the key features of this embodiment. It includes a hollow outer tube 13, the axis of which is typically parallel to the conveying direction of the rice noodles or can be adjusted as needed. At least two symmetrically arranged cutting plates 14 are slidably connected inside the outer tube 13. Multiple sharp cutting blades 15 are fixedly connected to the top of each cutting plate 14 (or the side facing the rice noodles). To achieve the cutting action, piezoelectric stacks 16 are fixedly connected to both ends of the cutting plates 14. These piezoelectric stacks 16 are preferably made of high-performance piezoelectric materials such as piezoelectric ceramics, which can generate precise and rapid cutting when a voltage is applied. For a small displacement, one of the two piezoelectric stacks 16 corresponding to the cutting plate 14 (or both via appropriate connectors) is fixedly connected to a cylinder 17 at its end away from the cutting plate 14. The cylinder 17 is preferably a double-acting cylinder, which can realize the bidirectional (extending and retracting) movement of the piston rod through air pressure control, thereby driving the piezoelectric stack 16 and the cutting plate 14 to perform the cutting action. In order to ensure the stability and accuracy of the cutting action, the cylinder 17 is fixedly connected to the outer tube 13 directly or through a connector. The sliding direction of the cutting plate 14 inside it is strictly coincident with the axial direction of the outer tube 13.

[0060] To achieve the "synchronous flying shear" function, which allows cutting of rice noodles during continuous conveying without stopping the conveyor belt, the outer end of the outer tube 13 is designed to be rotatably mounted. It passes through the base 10, and a gear 18 is firmly fixedly connected to the part of the outer tube 13 that passes through the base 10. On the base 10, corresponding to the position of gear 18, a drive motor (not shown) is installed. The power output shaft of the motor is fixedly connected to a gear 2 (not shown, but meshing with gear 18). Therefore, the motor drives the entire outer tube 13 (along with the internal cutting plate 14, cutting blade 15, piezoelectric stack 16, and cylinder 17) to rotate around its own axis through gear 2 and gear 18.

[0061] To further optimize the cutting process, prevent rice noodles from sticking to the blade, and clean the blade, a water tank 19 is fixedly connected to the bottom of the base 10 at a position corresponding to the outer tube 13 (especially below the rotation path of the cutting blade 15). The water tank 19 is filled with an appropriate amount of clean water or food-grade lubricant before use.

[0062] Work process

[0063] After being extruded by an extruder, rice noodles or rice vermicelli are continuously transported towards conveyor group 3 via the diverter plate of Example 1 and the smooth, anti-sticking conveyor groups 1 and 2.

[0064] When the rice noodles or rice vermicelli located between conveyor group 2 and conveyor group 3 reach the preset cutting length (usually determined by a detection device such as a photoelectric sensor or encoder, not shown in the figure), the control system issues a cutting command.

[0065] The motor mounted on the base 10 starts and drives gear 18 to rotate through gear 2. Gear 18 then drives the entire outer tube 13 and all the internal cutting components (cutting plate 14, cutting blade 15, piezoelectric stack 16, cylinder 17) to start rotating around the axis of the outer tube 13. The speed of this rotation is precisely calculated and controlled so that its linear speed is strictly synchronized with the conveying speed of rice noodles or rice vermicelli on the conveyor belt 6. In this way, when the cutting blade 15 contacts the rice noodles, there is almost no relative movement between the two, realizing synchronous flying shearing.

[0066] As the cutting assembly rotates, the double-acting cylinder 17 receives an action signal, and its piston rod extends (or retracts, depending on the design), pushing the connected piezoelectric stack 16, which in turn drives the left and right symmetrical cutting plates 14 to move rapidly towards each other. The cutting blades 15 fixed on the cutting plates 14 then close alternately, quickly cutting the rice noodles or rice vermicelli that are passing through.

[0067] At the moment the cutting blade 15 closes and cuts the rice noodles (or throughout the entire cutting process), the control system applies a high-frequency alternating voltage to the piezoelectric stack 16 made of piezoelectric material. The piezoelectric stack 16 then generates high-frequency stretching vibration. This tiny but extremely high-frequency vibration is transmitted to the cutting blade 15 through the cutting plate 14, causing the cutting blade 15 to also generate vibration at the same frequency. This high-frequency vibration greatly reduces the frictional resistance and cutting force during cutting, making the cutting process smoother, the cut flat and smooth, and less prone to burrs. It also effectively prevents the moist rice noodles from adhering to the blade.

[0068] As the entire cutting mechanism rotates, the lower cutting blade 15 periodically sweeps across or is immersed in the water in the lower water tank 19. The water can moisten the surface of the cutting blade 15, which acts as a lubricant during cutting, reducing adhesion and making the cutting smoother. On the other hand, after cutting, the movement of the cutting blade 15 in the water, especially under high-frequency vibration, can effectively wash away the tiny dust particles that may have adhered to the blade during cutting, achieving real-time cleaning of the cutting blade 15 and maintaining its sharpness.

[0069] After one cutting action is completed, the double-acting cylinder 17 reverses its action, causing the cutting plate 14 and the cutting blade 15 to quickly reset and open, preparing for the next cutting. The entire cutting mechanism continues to rotate synchronously with the rice noodle conveyor.

[0070] The cut rice noodle segment of a certain length continues to be conveyed forward a short, precise distance by conveyor group 2 and conveyor group 3 (or mainly by conveyor group 3), so that the midpoint of the rice noodle segment is exactly below the hanging rod 4. At this time, the control system commands the external lifting equipment to start, driving the hanging rod 4 to rise smoothly upward within the guide of the upper support 11 and the lower support 12. The rising hanging rod 4 gently lifts the midpoint of the rice noodle segment from below, and the rice noodle segment naturally falls down due to gravity, folds in half, and hangs on the hanging rod 4. After the hanging is completed, the hanging rod 4 with rice noodles can be removed manually or transferred by other automated devices to the subsequent drying, aging, or packaging station. Empty hanging rods will be automatically replenished by the replenishment mechanism (not shown), or the original hanging rod will be lowered and reset to prepare for the next hanging of rice noodles.

[0071] By driving gears 18 and 2 with a motor, the entire cutting mechanism (including outer tube 13, cutting plate 14, cutting blade 15, piezoelectric stack 16, and cylinder 17) rotates synchronously with the rice noodle conveyor, realizing the synchronous flying shear function of cutting while the rice noodles are continuously conveyed without stopping. This greatly improves production efficiency and avoids the mechanical impact and time waste caused by the frequent start and stop of the conveyor belt that may be caused by traditional intermittent cutting.

[0072] The piezoelectric stack 16, made of piezoelectric material, drives the cutting blade 15 to generate high-frequency vibration during cutting, which significantly reduces cutting resistance and makes the cutting process easier and faster. More importantly, vibration cutting can obtain a very flat and smooth cut without burrs or extrusion deformation, effectively preventing rice noodles from sticking to the cutting blade 15, thereby improving the quality and appearance of the final product.

[0073] The water tank 19 allows the rotating cutting blade 15 to periodically come into contact with water, which not only lubricates the blade during cutting, reducing rice flour adhesion and making cutting smoother, but also automatically cleans the cutting blade 15 after cutting with the help of high-frequency vibration and water flow, removing residual powder and maintaining the sharpness and hygiene of the blade, thus extending the service life of the blade.

[0074] Conveying groups 2 and 3 can precisely position the cut rice noodle segments below the hanging rod 4. With the help of the hanging rod 4, which is driven by external lifting equipment and guided and slids within the upper support 11 and lower support 12, the centering, lifting and hanging of the rice noodles can be completed automatically. The entire hanging process is highly automated, reducing manual operation, improving the efficiency and consistency of hanging, and ensuring the hygiene of the production process.

[0075] The cutting plate 14 is driven by a double-acting cylinder 17, which has a rapid response, sufficient power and reliable control. The cylinder 17 is fixedly connected to the outer tube 13. The design that the sliding direction of the cutting plate 14 coincides with the axial direction of the outer tube 13 ensures the linearity and stability of the cutting action. This is crucial for ensuring cutting accuracy and long-term stable operation of the equipment. The rotational connection of multiple rotating shafts 9 to the base 10, as well as the stable support of the base 10 for each component, also ensures the efficient and reliable operation of the whole machine.

It should be understood that the present utility model is not limited to the form disclosed herein and should not be regarded as an exclusion of other embodiments.
