Description

Technical Field

[0001] This invention belongs to the field of instant noodle production technology, specifically an automatic weighing device and method for packaging instant noodles. Background Technology

[0002] Instant noodles, as a food that is easy to store, transport, and consume quickly, typically require quantitative packaging according to sales specifications in the food processing industry to facilitate subsequent boxing, transportation, and market sales. Especially in the production of instant noodle crumbs, seasoned noodle ingredient packets, hot pot noodle cakes, snack food ingredients, and export bulk instant noodles, it is often necessary to automatically weigh the instant noodles according to preset weights and then package them into bags or boxes. Therefore, automatic weighing and packaging of instant noodles has become a crucial step in the instant noodle production process, and its packaging efficiency and quality directly affect product consistency, production efficiency, and enterprise production costs.

[0003] Existing automated instant noodle packaging equipment typically uses a storage hopper and a feeding mechanism to directly feed the instant noodles into a weighing container for weighing. Once the set weight is reached, the noodles are then transported to the packaging station for final packaging. However, instant noodles are a fluffy, porous, and irregularly shaped material, which can easily lead to uneven accumulation, localized gaps, and large internal voids during the feeding process. This results in significant differences in the volume occupied by the same weight of instant noodles, causing subsequent packaging bags to bulge, be unevenly filled, or have inconsistent packaging sizes. Furthermore, instant noodles usually go directly into the packaging process after weighing without effective equalization and compaction, resulting in irregular product appearance, low packaging space utilization, and impacting packaging quality and transportation stability. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic weighing device and method for packaging instant noodles, so as to solve at least one aspect of the problems and defects mentioned in the background art.

[0005] An automatic weighing device and method for instant noodle repackaging is provided, comprising a frame, a noodle storage bin above the frame, a conveying and distributing mechanism inside the noodle storage bin, a plurality of guiding and distributing mechanisms below the conveying and distributing mechanism, each of the guiding and distributing mechanisms being equipped with a material blocking mechanism, a circulating conveying mechanism below the guiding and distributing mechanism, a plurality of weighing components on the circulating conveying mechanism, a compaction component on one side above the circulating conveying mechanism, and an auxiliary material leveling component between the circulating conveying mechanism and the compaction component.

[0006] Furthermore, the conveying and distributing mechanism includes a distributing bin, which is located below the storage bin. The distributing bin is equipped with several distributing partitions, which divide the distributing bin into several guide chambers. Each of the guide chambers has a guide channel below it, and each guide channel has a guide distribution mechanism below it.

[0007] Furthermore, the guiding and distributing mechanism includes a guiding housing, which is disposed below the guiding channel. A buffer guide plate is disposed inside the guiding housing, and the buffer guide plate is rotatably connected inside the guiding housing via a rotating shaft. A guiding constriction end is disposed at the end of the guiding housing.

[0008] Furthermore, the material blocking mechanism includes a material blocking bracket, which is disposed on one side of the upper part of the guide housing. Material blocking cylinders are disposed on both sides of the upper part of the material blocking bracket. The telescopic ends of the two material blocking cylinders are connected to a material blocking mounting plate, and a plurality of material blocking plates are disposed on the material blocking mounting plate.

[0009] Furthermore, the circulating conveying mechanism includes a conveyor frame, with annular conveyor belts on both sides above the conveyor frame, and a plurality of placement plates between the two annular conveyor belts, each of which is equipped with a weighing component.

[0010] Furthermore, the weighing assembly includes a rotating base, which is rotatably connected to the placement plate via a rotating shaft. Each rotating base is equipped with a weighing box. A driven roller is provided at the lower end of the rotating shaft. Several driven rollers are connected by several transmission wheels. A weighing sensor is provided at the center of the upper part of the rotating base.

[0011] Furthermore, the auxiliary material leveling component includes a guide mounting frame, with guide mounting frames provided on both sides of the upper part of the frame, and guide rails provided on the guide mounting frames. The guide rails are located between the circulating conveying mechanism and the compaction component, and several auxiliary rollers are fixedly connected to the upper part of each guide rail.

[0012] Furthermore, the compaction assembly includes a compaction frame, which is disposed on one side of the upper part of the conveyor frame. A pressing cylinder is disposed on one side of the upper part of the compaction frame. A pressing head mounting seat is fixedly connected to the telescopic end of the pressing cylinder. Guide rods are also disposed on both sides of the pressing head mounting seat and the compaction frame. Several floating compaction heads are disposed below the pressing head mounting seat.

[0013] Furthermore, the floating compaction head includes a central compaction block, which is disposed on the compaction head mounting plate. An annular compaction ring is sleeved around the outer periphery of the central compaction block. The annular compaction ring is slidably connected to the outer side of the central compaction block through a plurality of floating guide posts. The floating guide posts are slidably connected in the guide holes of the annular compaction ring. A return spring is provided between the annular compaction ring and the compaction head mounting plate. Limiting retaining rings are also provided on both sides of the ends of the floating guide posts.

[0014] Furthermore, a weighing method for an automatic weighing device for repackaging instant noodles; S1. The instant noodles to be packaged are transported to the noodle storage bin, and then transported by the conveying and distributing mechanism to several guiding and distributing mechanisms to realize the storage and distribution of materials; S2. The circulating conveying mechanism drives the weighing component to run in a cycle. When the weighing component runs to the bottom of the corresponding guide distribution mechanism, the material blocking mechanism is opened, and the instant noodles enter the weighing component through the guide shell and the guide closing end to complete the fixed-point feeding. S3. The instant noodles in the weighing box are weighed in real time by the weighing sensor on the weighing component. When the weighing value reaches the preset weight, the corresponding material blocking mechanism is closed and the feeding stops. S4. After weighing, the weighing component moves to the compaction station with the circulating conveyor mechanism. When the weighing component runs to the area of ​​the auxiliary equalization component, the weighing component causes the weighing box to rotate through the auxiliary equalization component, thereby redistributing the instant noodles in the weighing box and filling the internal gaps. S5. The weighing component, after passing through the auxiliary equalization component, continues to run to the compaction component, where it achieves graded compaction. The circulating conveyor continues to transport the weighing component to the unloading station, where the compacted instant noodles are output to the subsequent packaging process.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: The instant noodles in the noodle storage compartment are diverted by the conveying and distributing mechanism and then enter multiple guiding and distributing mechanisms. The timing of feeding is controlled by the material blocking mechanism, so that the instant noodles can enter the corresponding weighing components at fixed points for weighing, thereby improving the stability of the feeding process and the weighing accuracy. Meanwhile, since instant noodles are a fluffy and irregularly shaped material, they are prone to local accumulation, gaps, and large internal voids after entering the weighing component. This application sets an auxiliary material leveling component between the circulating conveying mechanism and the compaction component. When the weighing component moves with the circulating conveying mechanism after weighing, the auxiliary material leveling component can drive the weighing component 7 to rotate, so that the instant noodles in the weighing box are redistributed, reducing local accumulation and filling the internal voids of the instant noodles, thereby improving the uniformity of the instant noodles in the weighing box. After being assisted in equalizing the material, the weighing component continues to move below the compaction component. The compaction component compacts the instant noodles inside the weighing box, further reducing the residual voids within the noodles and increasing the bulk density of the noodles per unit volume. This results in a more consistent volume for noodles of the same weight, reducing issues such as bulging bags, uneven filling, and significant differences in packaging dimensions during subsequent packaging processes. This improves the uniformity of the packaged appearance and the utilization rate of packaging space. At the same time, the compacted instant noodles have a more stable overall structure, which is beneficial to the product stability during subsequent conveying, boxing, and transportation, thereby improving the quality and production efficiency of automatic instant noodle repackaging.

It should be understood that the specific embodiments described herein are only for explaining the invention and are not intended to limit the invention; that is, the described embodiments are merely some embodiments of the invention, and not all embodiments. The components of the embodiments of the invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0024] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0025] Please see Figure 1-7 As shown in the embodiment of the present invention, an automatic weighing device for instant noodle repackaging includes a frame 1, a noodle storage bin 2 is arranged above the frame 1, a conveying and distributing mechanism 3 is arranged inside the noodle storage bin 2, a plurality of guiding and distributing mechanisms 4 are arranged below the conveying and distributing mechanism 3, a blocking mechanism 5 is arranged on each of the plurality of guiding and distributing mechanisms 4, a circulating conveying mechanism 6 is arranged below the guiding and distributing mechanism 4, a plurality of weighing components 7 are arranged on the circulating conveying mechanism 6, a compaction component 8 is arranged on one side above the circulating conveying mechanism 6, and an auxiliary equalizing component 9 is arranged between the circulating conveying mechanism 6 and the compaction component 8. The instant noodles in the noodle storage compartment 2 are diverted by the conveying and distributing mechanism 3 and then enter multiple guiding and distributing mechanisms 4. The feeding timing is controlled by the material blocking mechanism 5, so that the instant noodles can enter the corresponding weighing component 7 at a fixed point for weighing, thereby improving the stability of the feeding process and the weighing accuracy.

[0026] Meanwhile, since instant noodles are a fluffy and irregularly shaped material, they are prone to local accumulation, gaps, and large internal voids after entering the weighing component 7. This application provides an auxiliary equalizing component 9 between the circulating conveying mechanism 6 and the compaction component 8. When the weighing component 7 moves with the circulating conveying mechanism 6 after weighing, the auxiliary equalizing component 9 can drive the weighing component 7 to rotate, redistributing the instant noodles within the weighing box 73, reducing local accumulation, filling the internal voids of the instant noodles, and thus improving the uniformity of the instant noodles within the weighing box 73. After being assisted in equalizing, the weighing component 7 continues to move to the compaction component 8. Below the compaction component 8, the instant noodles inside the box 73 are compacted by the compaction component 8, which further reduces the residual voids inside the instant noodles, increases the bulk density of the instant noodles per unit volume, and makes the instant noodles of the same weight have a more consistent volume state. This reduces the occurrence of packaging bag bulging, uneven filling, and large differences in packaging size during subsequent packaging processes, improves the consistency of the appearance after packaging and the utilization rate of packaging space. At the same time, the overall structure of the compacted instant noodles is more stable, which is conducive to the product stability during subsequent conveying, boxing and transportation, thereby improving the quality and production efficiency of automatic instant noodle repackaging.

[0027] In one embodiment, see Figure 1 , Figure 2 and Figure 3As shown, the conveying and distributing mechanism 3 includes a distributing bin 31, which is located below the storage bin 2. The distributing bin 31 is equipped with several distributing partitions 32, which divide the distributing bin 31 into several guide chambers 33. Each of the several guide chambers 33 is equipped with a guide channel 34, and each of the guide channels 34 is equipped with a guide distribution mechanism 4. A large quantity of instant noodles awaiting repackaging is first stored inside the noodle storage compartment 2. The bottom of the noodle storage compartment 2 is connected to the distribution compartment 31. The instant noodles gradually enter the distribution compartment 31 under their own gravity. Since there are several distribution partitions 32 arranged along the width direction inside the distribution compartment 31, the distribution partitions 32 divide the distribution compartment 31 into multiple independent guide chambers 33. Each guide chamber 33 corresponds to a guide and distribution mechanism 4 below. When the instant noodles enter the distribution compartment 31, the material is dispersed into the interior of each guide chamber 33 and flows downward along the guide chamber 33. Subsequently, the instant noodles enter the guide channel 34 set at the lower end of the guide cavity 33. The guide channel 34 restricts and guides the flow direction of the instant noodles, so that the instant noodles are conveyed downward along the predetermined trajectory to the corresponding guide distribution mechanism 4. Through the cooperation of multiple guide cavities 33 and multiple guide channels 34, a large batch of instant noodles in the noodle storage bin 2 can be simultaneously conveyed to multiple feeding stations, realizing synchronous feeding of multiple stations. This provides a stable material source for the subsequent material blocking mechanism 5 to control the feeding and the quantitative weighing of the weighing group 7, thereby improving the automated packaging efficiency and continuous production capacity of the whole machine.

[0028] In one embodiment, see Figure 1 , Figure 2 and Figure 3 As shown, the guiding and distributing mechanism 4 includes a guiding housing 41, which is located below the guiding channel 34. A buffer guide plate 42 is installed inside the guiding housing 41, and the buffer guide plate 42 is rotatably connected to the inside of the guiding housing 41 via a rotating shaft 43. A guiding constriction end 44 is provided at the end of the guiding housing 41. Instant noodles conveyed by the conveying and distributing mechanism 3 first enter the guiding housing 41 through the guiding channel 34. Upon entering the guiding housing 41, the instant noodles first contact the buffer guide plate 42 inside the housing. Because the buffer guide plate 42 is rotatably connected to the inner wall of the guiding housing 41 via the rotating shaft 43, it can oscillate slightly around the rotating shaft 43 under the continuous impact of the falling instant noodles. After contact with the buffer guide plate 42, the falling speed of the instant noodles is buffered, and the falling direction changes from vertical free fall to sliding fall along the surface of the buffer guide plate 42, thereby reducing the collision and impact between instant noodles and between the instant noodles and the equipment, and reducing the breakage rate. As the instant noodles continuously enter the guide housing 41, the buffer guide plate 42 continuously oscillates slightly under the combined action of gravity and the force of the material, creating a relatively uniform flow of the instant noodles within the guide housing 41. This reduces material accumulation on one side, which could affect the stability of the feeding process. Subsequently, the instant noodles, after being buffered and guided, continue to move downwards and enter the guide closing end 44 at the end of the guide housing 41. The flow cross-sectional area of ​​the guide closing end 44 gradually decreases, causing the dispersed instant noodles to gradually converge towards the central area and fall along the outlet of the guide closing end 44, ultimately accurately entering the corresponding weighing component 7 below. Through the combined action of the buffer guide plate 42 and the guide closing end 44, not only is the stability and uniformity of the instant noodle feeding process improved, but the breakage rate of the instant noodles is also reduced, providing a good material condition for subsequent weighing, uniformization, and compaction processes.

[0029] In one embodiment, see Figure 1 , Figure 2 and Figure 4 As shown, the material blocking mechanism 5 includes a material blocking bracket 51, which is disposed on one side of the upper part of the guide housing 41. Material blocking cylinders 52 are disposed on both sides of the upper part of the material blocking bracket 51. The telescopic ends of the two material blocking cylinders 52 are connected to a material blocking mounting plate 53. A plurality of material blocking plates 54 are disposed on the material blocking mounting plate 53. A baffle bracket 51 is fixedly installed on one side of the upper part of the guide housing 41. Two baffle cylinders 52 are respectively installed on both sides of the baffle bracket 51. The telescopic ends of the two baffle cylinders 52 are connected to both ends of the baffle mounting plate 53, so that the baffle mounting plate 53 can move smoothly under the synchronous drive of the two baffle cylinders 52. Several baffle plates 54 are provided on the baffle mounting plate 53 along the length direction. The position of each baffle plate 54 corresponds to the position of the corresponding guide channel 34, and the outer dimensions of the baffle plate 54 match the outlet dimensions of the guide channel 34. In the initial stage of equipment operation, the baffle cylinder 52 is in the extended state, which drives the baffle mounting plate 53 to move to the baffle position. At this time, each baffle plate 54 is located at the outlet of the corresponding guide channel 34, forming a closure of the guide channel 34. The instant noodles falling in the noodle storage bin 2 are blocked inside the guide channel 34 and the guide housing 41, preventing the instant noodles from falling into the weighing component 7 below in advance. When the circulating conveyor 6 drives the weighing component to run below the corresponding guide distribution mechanism 4, the control system sends an action command to the baffle cylinder 52 according to the position signal of the weighing component 7. The two baffle cylinders 52 retract synchronously, driving the baffle mounting plate 53 to move as a whole, so that each baffle plate 54 is disengaged from the outlet position of the corresponding guide channel 34. At this time, the guide channel 34 is in the open state, and the instant noodles flow downward through the guide housing 41 under its own gravity, and enter the corresponding weighing component 7 below through the guide closing end 44 to complete the feeding.

[0030] When the weighing component 7 reaches the preset weight or leaves the unloading station, the baffle cylinder 52 extends again, pushing the baffle mounting plate 53 to reset. Each baffle plate 54 then re-closes the outlet of the corresponding guide channel 34, stopping the instant noodles from falling further, thus completing one unloading cycle. Through the cooperation between the baffle mechanism 5, the guide channel 34, the guide distribution mechanism 4, and the weighing component 7, the instant noodles are unloaded at fixed points, in fixed quantities, and synchronously, providing stable material supply conditions for subsequent weighing and compaction processes.

[0031] In one embodiment, see Figure 4 , Figure 5 and Figure 6 As shown, the circulating conveying mechanism 6 includes a conveyor frame 61, with annular conveyor belts 62 arranged on both sides above the conveyor frame 61. A plurality of placement plates 63 are arranged between the two annular conveyor belts 62, and each of the placement plates 63 is equipped with a weighing component 7. The placement plates 63 are uniformly and fixedly connected between the two annular conveyor belts 62 along the conveying direction, so that the placement plates 63 can move synchronously with the annular conveyor belts 62. Each placement plate 63 is equipped with a set of weighing components 7. When the circulating conveying mechanism 6 is running, each placement plate 63 carries the corresponding weighing components 7 and moves sequentially along the circulating path. First, the empty weighing assembly 7 moves to below the guiding and distributing mechanism 4. At this time, the material blocking mechanism 5 opens, and the instant noodles enter the weighing assembly 7 to complete the weighing. After weighing, the circular conveyor belt 62 continues to drive the placement plate 63 forward, so that the weighing assembly 7 enters the area of ​​the auxiliary material leveling assembly 9, and completes the rotational material leveling of the instant noodles during the conveying process. Then, the weighing assembly 7 continues to move to below the compaction assembly 8, where the compaction assembly 8 compacts the instant noodles in the weighing box 73. After compaction, the circulating conveyor mechanism 6 continues to drive the weighing assembly 7 to the unloading station, and conveys the compacted instant noodles to the subsequent packaging process. Since multiple placement plates 63 are evenly arranged around the circumference of the circular conveyor belt 62, during the operation of the equipment, different weighing assemblies 7 can be located at different stations such as feeding, weighing, material leveling, compaction, and unloading, realizing multi-station synchronous operation. While one weighing component 7 is weighing, another weighing component 7 can simultaneously perform material equalization or compaction, thus forming a continuous cycle production mode and improving the overall processing capacity and automated production efficiency of the equipment. Through the cooperation between the conveyor frame 61, the ring conveyor belt 62, and the placement plate 63, stable cyclic conveying of the weighing components 7 is achieved, providing a reliable operating foundation for the entire automatic weighing, equalization, and compaction process of instant noodles.

[0032] In one embodiment, see Figure 4 , Figure 5 and Figure 6As shown, the weighing assembly 7 includes a rotating base 71, which is rotatably connected to the placement plate 63 via a rotating shaft 72. Each rotating base 71 is equipped with a weighing box 73. A driven roller 74 is located at the lower end of the rotating shaft 72, and several driven rollers 74 are connected via several transmission wheels 75. A weighing sensor 76 is located at the center of the upper part of the rotating base 71. The circulating conveying mechanism 6 drives the placement plate 63 to circulate along the conveying path. When an empty weighing assembly 7 reaches below the corresponding guide distribution mechanism 4, the baffle mechanism 5 opens, and the instant noodles enter the weighing box 73 through the guide housing 41 and the guide closing end 44. As instant noodles continuously enter the weighing box 73, the weight borne by the weighing box 73 is transferred to the weighing sensor 76 located at the center of its upper part through the rotating base 71. The weighing sensor 76 collects the weight signal in real time and transmits it to the control system. When the weighing value reaches the preset weight, the control system controls the material blocking mechanism 5 to close and stop feeding, thereby completing a quantitative weighing process. Subsequently, the weighing component 7 continues to move forward with the circulating conveyor mechanism 6. When the weighing component 7 enters the auxiliary equalization area, the driven roller 74 located below forms rolling contact with the auxiliary equalization component 9. One of the driven rollers 74 is driven to rotate first. Since each driven roller 74 is mutually transmitted through the transmission wheel 75, the rotational motion can be transmitted to the other driven rollers 74 in sequence, causing multiple rotating shafts 72 to rotate synchronously. After the rotating shafts 72 rotate, they drive the rotating seat 71 and the weighing box 73 to rotate synchronously, thereby causing the instant noodles in the weighing box 73 to be flipped, rolled and redistributed, reducing local accumulation and internal gaps, and making the instant noodles form a more uniform accumulation state in the box. After being evenly mixed, the weighing component 7 continues to the compaction station, where the compaction component 8 compacts the instant noodles inside the weighing box 73. Since the instant noodles have been rotated and evenly mixed before compaction, the internal void distribution is more uniform, thus improving the compaction effect and the consistency of the packaged product. Through the coordinated operation of the rotating seat 71, rotating shaft 72, driven roller 74, transmission wheel 75, and weighing sensor 76, automatic weighing, automatic even mixing, and stable conveying of the instant noodles are achieved, improving the automation level and packaging quality of the entire subpackaging process.

[0033] In one embodiment, see Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, the compaction assembly 8 includes a compaction frame 81, which is located on one side of the upper part of the conveyor frame 61. A pressing cylinder 82 is installed on one side of the upper part of the compaction frame 81. The telescopic end of the pressing cylinder 82 is fixedly connected to a pressing head mounting seat 83. Guide rods 84 are also provided on both sides of the pressing head mounting seat 83 and the compaction frame 81. Several floating compaction heads 85 are arranged below the pressing head mounting seat 83. The compaction frame 81 is fixedly installed at the upper compaction position of the frame 1, forming a stable compaction support structure. The pressing cylinder 82 is installed on one side of the upper part of the compaction frame 81, with its telescopic end arranged vertically downward and fixedly connected to the pressing head mounting seat 83. When the weighing assembly 7 runs to the compaction position with the circulating conveyor mechanism 6, the control system controls the pressing cylinder 82 to move, causing its telescopic end to drive the pressing head mounting seat 83 downward. During the descent of the pressure head mounting base 83, it is guided and limited by the guide rods 84 set on both sides of it, so that the pressure head mounting base 83 always maintains a vertical movement state, avoiding deviation or tilting during the compaction process, thereby ensuring that the compaction effect is evenly applied to the inside of the weighing box 73. When the pressure head mounting base 83 descends to the contact position with the weighing box 73, the floating compaction head 85 first contacts the surface of the instant noodles. Due to the elastic floating structure of the floating compaction head 85, it can buffer and pre-compress the instant noodles in the initial contact stage, reducing the impact force. Subsequently, under the continuous action of the pressing cylinder 82, the floating compaction head 85 gradually applies stable pressure to the instant noodles, causing the air inside the instant noodles to be expelled and the structure to rearrange, thereby achieving the compaction effect. After compaction, the pressing cylinder 82 retracts, and the pressing head mounting seat 83 rises and resets under the action of the guide rod 84. The floating compaction head 85 then detaches from the weighing box 73, and the circulating conveying mechanism 6 continues to drive the weighing assembly 7 to the next station, thereby completing the compaction process of a single weighing box 73. Through the above structural coordination, a stable and controllable pressing and compaction process is achieved, improving the consistency of the instant noodles after repackaging and the packaging quality.

[0034] In one embodiment, see Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, the auxiliary material leveling component 9 includes a guide mounting frame 91. Guide mounting frames 91 are arranged on both sides of the upper part of the frame 1, and guide rails 92 are mounted on the guide mounting frames 91. The guide rails 92 are positioned between the circulating conveying mechanism 6 and the compaction component 8. Several auxiliary rollers 93 are fixedly connected to the upper part of each guide rail 92. The guide mounting frames 91 are fixedly mounted on both sides of the upper part of the frame 1, forming an auxiliary material leveling station area between the two guide mounting frames 91. Guide rails 92 are fixedly mounted on the guide mounting frames 91, extending along the running direction of the circulating conveying mechanism 6 and located between the weighing station and the compaction station. Several auxiliary rollers 93 are spaced apart along the length of the upper part of the guide rails 92, and each auxiliary roller 93 is rotatably mounted on the guide mounting frame 91. When the circulating conveyor 6 drives the weighing component 7 to run, the weighing component 7, having completed weighing, enters the auxiliary equalization area. At this time, the driven roller 74 at the lower end of the rotating shaft 72 gradually comes into contact with the guide rail 92 and the auxiliary roller 93. Since the auxiliary roller 93 can rotate freely, as the circulating conveyor 6 continues to move forward, the driven roller 74 rolls forward along the guide rail 92, and at the same time rotates due to the rolling friction of the auxiliary roller 93. After the driven roller 74 rotates, it drives the rotating shaft 72 to rotate synchronously. The rotating shaft 72 further drives the rotating base 71 and the weighing box 73 to rotate around their own axis. During the rotation, the instant noodles in the weighing box 73 are flipped, rolled and rearranged, causing the instant noodles that were originally concentrated in a local area to gradually spread to the surrounding area. At the same time, the larger empty area inside is filled with the surrounding instant noodles, thereby improving the uniformity of the instant noodles' accumulation.

[0035] In one embodiment, see Figure 5 and Figure 7 As shown, the floating compaction head 85 includes a central compaction block 851, which is disposed on the compaction head mounting plate 852. An annular compaction ring 853 is sleeved on the outer periphery of the central compaction block 851. The annular compaction ring 853 is slidably connected to the outer side of the central compaction block 851 through a plurality of floating guide posts 854. The floating guide posts 854 are slidably connected in the guide holes of the annular compaction ring 853. A reset spring 855 is provided between the annular compaction ring 853 and the compaction head mounting plate 852. The reset spring 855 is sleeved above the floating guide posts 854. Limiting retaining rings 856 are also provided on both sides of the end of the floating guide posts 854. The floating compaction head 85 is mainly used for graded compaction of instant noodles inside the weighing box 73. This allows the instant noodles to undergo initial outer-area shaping and compression before central compensation compaction, thereby improving compaction uniformity and reducing noodle breakage. Since instant noodles are a loose and fragile material, large gaps easily form between their edges and the inner wall of the weighing box 73. Direct, overall compaction could lead to excessive pressure in the central area and insufficient compaction in the outer areas. Therefore, this application uses a two-stage compaction structure formed by the central compaction block 851 and the annular compaction ring 853 to achieve gradual compaction from the outside in. In practical use, the annular pressure ring 853 is sleeved on the outer periphery of the central pressure block 851. The annular pressure ring 853 is slidably connected to the central pressure block 851 through several floating guide posts 854. The floating guide posts 854 are slidably installed in the guide holes of the annular pressure ring 853. A return spring 855 is provided between the annular pressure ring 853 and the pressure head mounting plate 852. A limit stop ring 856 is provided at the end of the floating guide post 854 to limit the maximum displacement range of the annular pressure ring 853. The lower pressure surface of the annular pressure ring 853 protrudes downward relative to the lower pressure surface of the central pressure block 851. When the pressure cylinder 82 drives the pressure head mounting plate 852 to move downward, the annular pressure ring 853 first contacts the outer area of ​​the instant noodles inside the weighing box 73 and pre-compresses the outer instant noodles, filling the gaps at the edge of the instant noodles and forming an outer constraint structure to limit the outward spread of the instant noodles. As the pressure head continues to move downward, the annular pressure ring 853 is subjected to the reaction force of the instant noodles and floats upward relative to the pressure head mounting plate 852. The return spring 855 is gradually compressed. When the central pressure block 851 continues to descend to the predetermined stroke, the central pressure block 851 begins to contact the central area of ​​the instant noodles and further compacts the central accumulation area, causing the instant noodles to gradually gather from the outside to the center, achieving uniform compaction of the whole. After compaction, the lower cylinder 82 returns to its original position, the reset spring 855 releases its elastic potential energy and pushes the annular pressure ring 853 to reset, and the floating guide post 854 returns to its initial position under the restriction of the limiting ring 856, thus completing one compaction cycle. By compacting the annular pressure ring 853 first and then the central pressure block 851, the step-by-step compaction method can not only effectively reduce the gaps at the edges of the instant noodles and improve the volume consistency after packaging, but also reduce the breakage rate of the instant noodles during the compaction process and improve the quality of subsequent packaging.

[0036] In one embodiment, see Figure 1 , Figure 3 , Figure 4 and Figure 6As shown, a weighing method for an automatic weighing device for instant noodle repackaging includes the following steps: S1, the instant noodles to be repackaged are conveyed to the noodle storage bin 2, and then conveyed to several guiding and distributing mechanisms 4 by the conveying and distributing mechanism 3 to realize material storage and distribution; the centrally stored instant noodles are diverted through multiple channels and conveyed to multiple guiding and distributing mechanisms 4 to realize the pre-distribution of materials.

[0037] S2. The circulating conveying mechanism 6 drives the weighing component 7 to run in a cycle. When the weighing component 7 runs to the bottom of the corresponding guide distribution mechanism 4, the material blocking mechanism 5 opens and enters the weighing component 7 to complete the fixed-point feeding, ensuring that the weighing box 73 is accurately aligned with the feeding port, and reducing the phenomenon of premature feeding or misaligned material distribution. S3. The weighing sensor 76 on the weighing component 7 performs real-time weight detection on the instant noodles in the weighing box 73. When the weighing value reaches the preset weight, the corresponding material blocking mechanism 5 is closed to stop feeding, thereby improving the weight consistency of each serving of instant noodles. S4. After weighing, the weighing component 7 moves to the compaction station with the circulating conveying mechanism 6. When the weighing component 7 runs to the area of ​​the auxiliary equalization component 9, the weighing component 7 causes the weighing box 73 to rotate through the auxiliary equalization component 9, thereby redistributing the instant noodles in the weighing box 73 and filling the internal gaps, eliminating the uneven accumulation of instant noodles and the phenomenon of local voids, redistributing the internal gaps of the material, and improving the uniformity of subsequent compaction. S5. The weighing component 7, after passing through the auxiliary equalization component 9, continues to run to the compaction component 8. The compaction component 8 achieves graded compaction. The circulating conveying mechanism 6 continues to transport the weighing component 7 to the unloading station, and outputs the compacted instant noodles to the subsequent packaging process. This achieves graded compaction with central compaction and peripheral supplementary compaction, reducing the internal porosity of the instant noodles.
