Description

Technical Field

[0001] This application relates to the technical field of noodle packaging, and more particularly, to a packaging machine Background Art

[0002] Noodles have increasingly become an indispensable staple food for humans, an important part of the convergence of Chinese and Western civilizations, and have even given rise to the development of noodle machines. In order to make noodles more conveniently and quickly, people have invented a variety of artificial auxiliary instruments, which is a huge progress in human food culture. In today's society, there are various types of packaging machines on the market. For example, classified by product state, there are liquid, block, and granular packaging machines; classified by packaging function, there are inner packaging and outer packaging machines; classified by packaging industry, there are food, daily chemical, textile, etc. packaging machines; classified by packaging stations, there are single-station and multi-station packaging machines; classified by automation level, there are semi-automatic and fully automatic packaging machines, etc.

[0003] So many packaging machines can only package products without considering the shape. Therefore, there is a fully automatic fresh noodle packaging machine. However, for the existing fresh noodle packaging machine equipment on the market, when weighing, it cannot ensure the neatness of the noodles. To ensure the neatness of the noodles, manual weighing is required. Therefore, on the market, there are only weighing and packaging machines that do not ensure the neatness of the noodles, or manual weighing and sorting are required to ensure the neatness of the noodles, and then packaging is achieved through a packaging machine. It is impossible to achieve weighing and noodle sorting together, resulting in low production efficiency and high labor costs. Summary of the Invention

[0004] The purpose of this application is to address the above problems by providing a packaging machine that can weigh, sort, and bag semi-dry noodles, improving the accuracy of the products produced, accelerating the packaging efficiency, reducing labor costs, and thus improving the above problems.

[0005] This application provides a packaging machine for packaging semi-dry noodles, including a conveying device, a weighing device, a first sorting device, a second sorting device, and a bagging device; the conveying device drives the semi-dry noodles to move in a first direction, the length direction of the semi-dry noodles is a second direction, and the first direction is perpendicular to the second direction; the weighing device weighs the semi-dry noodles; the first sorting device sorts the weighed semi-dry noodles into a figure-eight noodle bundle; the second sorting device sorts and compresses the noodle bundle; the bagging device packs the compressed noodle bundle into a packaging bag.

[0006] In the technical solution of the embodiment of this application, the packaging machine includes a conveying device, a weighing device, a first sorting device, a second sorting device, and a bagging device, which can weigh, sort, and bag semi-dry noodles, ensuring both the neatness of the noodles and achieving weighing and packaging. This mechanized assembly line production has high metering accuracy, high efficiency, saves materials, and reduces labor costs at the same time.

[0007] In some embodiments, the first sorting device includes a support plate, a traction hook, a first driving assembly, and a first pusher; the support plate includes a sorting area for placing the semi-dry noodles; the traction hook hooks the middle of the semi-dry noodles; the first driving assembly is connected to the traction hook and drives the traction hook to move along the first direction, so that the semi-dry noodles are bent into a U shape, and the semi-dry noodles are pulled to the sorting area for sorting; the first pusher is arranged on the support plate and pushes the semi-dry noodles away from the sorting area along the second direction.

[0008] In the technical solution of the embodiment of the present application, the semi-dry noodles fall from the end of the conveying device onto the weighing device. After weighing, the traction hook hooks the middle of the semi-dry noodles and moves along the first direction towards the support plate. The two ends of the semi-dry noodles move towards the opposite direction of the moving direction as the traction hook moves, and are bent into a U shape. The semi-dry noodles move to the sorting area and are sorted into an 8 shape, reducing the probability of the noodle bundle in the packaging bag spreading out and facilitating consumers to pick up. The first pusher pushes the sorted noodle bundle away from the sorting area and makes it enter the second sorting device. The sorting process of the semi-dry noodles is continuous and fast, and the processing efficiency is high.

[0009] In some embodiments, the first driving assembly includes a first driving member, a second driving member, and a third driving member; the first driving member drives the traction hook to move along the first direction, so that the semi-dry noodles are bent into a U shape; the second driving member drives the traction hook to rotate along the first direction to sort the semi-dry noodles into an 8 shape; the third driving member drives the traction hook to move along the third direction away from the support plate to disengage from the semi-dry noodles, and the first direction, the second direction, and the third direction are perpendicular to each other in pairs.

[0010] In the technical solution of the embodiment of the present application, the first driving member drives the traction hook to pull the weighed semi-dry noodles away from the weighing device and pull them to the sorting area. Then, the second driving member drives the traction hook to rotate along the first direction. The U-shaped semi-dry noodles rotate as the traction hook rotates and are wound into a continuous 8 shape. The third driving member drives the traction hook to move along the third direction. The folding edge of the rotated traction hook faces the support plate along the first direction. The noodle bundle stays in the sorting area under the action of its own weight, and the traction hook disengages from the noodle bundle, avoiding the movement path of the first pusher, so that the processing process can proceed continuously.

[0011] In some embodiments, the support plate is further provided with a first avoidance groove, and the traction hook extends into the first avoidance groove when it is flipped under the drive of the second driving member.

[0012] In the technical solution of the embodiment of the present application, when the towing hook rotates under the drive of the second driving member and extends into the first avoidance groove, the distance between the towing hook and the support plate in the third direction is relatively short, so that the semi-dry noodles can be placed on the support plate during the rotation process, reducing the risk of the semi-dry noodles falling off the towing hook during the rotation process.

[0013] In some embodiments, the weighing device includes a weighing member and a sensor. The weighing member includes a connecting edge and a supporting edge. The two supporting edges are arranged opposite to each other along the second direction. The connecting edge connects the two supporting edges. The connecting edge and the two supporting edges enclose a space for accommodating the towing hook. The sensor is used to measure the weight of the semi-dry noodles conveyed by the conveying device to the weighing member.

[0014] In the technical solution of the embodiment of the present application, during the weighing process, the towing hook is located inside the space enclosed by the connecting edge and the two supporting edges. The two supporting edges support the middle part of the semi-dry noodles. The sensor measures the weight of the semi-dry noodles hanging on the weighing member. After the weighing is completed, the towing hook moves along the first direction, passes through between the two connecting edges and takes away the noodles hanging on the two connecting edges. The supporting device provided by the present application can timely record the weight of the noodle bundle, facilitate the adjustment of the weight of the finished product, make the weighed weight within the rated range, and improve the production efficiency of the finished product while improving the accuracy of the weight of the finished product.

[0015] In some embodiments, the second sorting device includes a frame, a fifth driving member, a material box and a second driving assembly; the frame includes a first frame, a second frame and a fourth driving member. The second frame is rotatably connected to the first frame. The fourth driving member drives the second frame to rotate around the first direction as the axis; the fifth driving member is connected to the first frame and drives the frame to move along the third direction. The first direction, the second direction and the third direction are perpendicular to each other in pairs; the material box is arranged on the second frame; the second driving assembly drives the material box to deform to sort and press the noodle bundle.

[0016] In the technical solution of the embodiment of the present application, the second frame rotates under the drive of the fourth driving member, and the material box rotates with the rotation of the second frame. When the material box receives the noodle bundle, the length direction of the material box is parallel to the second direction. Along the second direction, a part of the material box and the support plate facing away from the first pushing member overlap, so that the noodle bundle can fall into the material box. The fifth driving member drives the material box to move along the third direction towards the support plate, shortening the falling distance of the noodle bundle and reducing the risk of the noodles being damaged due to falling; when the material box sends the sorted noodle bundle to be bagged, the direction of the material box is parallel to the third direction, and the opening of the material box facing away from the support plate is directly opposite to the opening of the packaging bag. The noodle bundle in the material box can slide towards the packaging bag under the action of gravity. The fifth driving member drives the material box to move along the third direction away from the support plate, shortening the distance between the material box and the packaging bag and reducing the risk of the noodle bundle in the material box falling to the outside.

[0017] In some embodiments, the hopper includes a first structural member and a second structural member; the first structural member includes a first side and a second side, and the first side is perpendicular to the second side; the second structural member includes a third side and a fourth side, and the third side is perpendicular to the fourth side; the first side and the third side are oppositely arranged along the first direction, the second side and the fourth side are stacked, and the second driving assembly includes a sixth driving member, and the sixth driving member drives the second connecting member to move along the second direction to press the semi-dry noodles placed on the second side.

[0018] In the technical solution of the embodiment of the present application, when the hopper receives the noodle bundle, the second side is closer to the support portion than the fourth side, and the second side blocks a part of the fourth side. Most of the noodle bundles falling from the support plate are located on the second side. After the noodle bundle is received, the sixth driving member drives the second connecting member to move along the second direction, so that the distance between the first side and the third side is shortened. The part of the noodle bundle located on the fourth side is pushed by the third side to move towards the second side, and the blocking area of the second side on the fourth side gradually increases until the second side completely blocks the fourth side, so that the noodle bundles are neatly arranged on the second side, reducing the risk of bending and breaking when the noodle bundles enter the packaging bag.

[0019] In some embodiments, the hopper further includes a third structural member, the third structural member includes a fifth side and two sixth sides, the two sixth sides are oppositely arranged along the first direction, the fifth side connects the two sixth sides, and along the first direction, the first side and the third side are located between the two sixth sides, and the first side, the second side, the third side and the fifth side enclose a space for pressing the noodle bundle; the second driving assembly further includes a seventh driving member, and the seventh driving member drives the third structural member to approach or move away from the first structural member.

[0020] In the technical solution of the embodiment of the present application, when the hopper receives the noodle bundle, the third structural member moves away from the first structural member along the third direction, reducing the chance of blocking the second side. After the noodle bundle is received and the noodle bundle is neatly arranged under the push of the second structural member, the third structural member moves towards the first structural member under the drive of the seventh driving member, and the fifth side and the second side squeeze the noodle bundle along the third direction, so that the gap between the semi-dry noodles is reduced, they fit together, are not easily deformed, and the total volume of the noodle bundle is reduced, facilitating entry into the packaging bag.

[0021] In some embodiments, the second sorting device further includes a second pushing member, and the second pushing member is used to push the noodle bundle in the hopper along the third direction, and the first direction, the second direction and the third direction are perpendicular to each other in pairs.

[0022] In the technical solution of the embodiment of the present application, when the noodle box sends out the noodle bundle towards the packaging bag, the output end of the second pusher can extend into the noodle box and push the noodle bundle in the noodle box along the first direction, reducing the probability of the noodles sticking to the inner wall of the noodle box.

[0023] In some embodiments, the bagging device includes a clamping jaw, a suction cup and an eighth driving member; the clamping jaw is used to clamp the packaging bag; the suction cup adsorbs one side of the opening of the packaging bag; the eighth driving member drives the suction cup to move in a direction away from the packaging bag to open the packaging bag.

[0024] In the technical solution of the embodiment of the present application, before the bagging operation, the clamping jaw clamps the packaging bag, the suction cup adsorbs one side of the opening of the packaging bag, and under the drive of the eighth driving member, it moves in the second direction away from the packaging bag to open the opening of the packaging bag, facilitating the entry of the noodle bundle.

[0025] Additional aspects and advantages of the present application will be given in part in the following description, become apparent in part from the following description, or be learned through the practice of the present application. Description of the Drawings

The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described in this application can be combined with other embodiments.

[0042] In the description of this application, it should be noted that, unless otherwise clearly specified and defined, the terms "installed", "connected", "coupled", and "attached" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0043] The term "and / or" in this application is merely a description of the association relationship of associated objects, indicating that three relationships can exist. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this application generally represents an "or" relationship between the preceding and following associated objects.

[0044] The "plurality" mentioned in this application refers to two or more (including two). Similarly, "multiple groups" refers to two or more groups (including two groups), and "multiple pieces" refers to two or more pieces (including two pieces).

[0045] According to some embodiments of this application, such as Figures 1 - 2As shown in the figure, the present application provides a packaging machine for packaging semi-dry noodles, which includes a conveying device 1, a weighing device 2, a first sorting device 3, a second sorting device 4, and a bagging device 5; the conveying device 1 drives the semi-dry noodles to move along the first direction X, the length direction of the semi-dry noodles is the second direction Y, and the first direction X is perpendicular to the second direction Y; the weighing device 2 weighs the semi-dry noodles; the first sorting device 3 sorts the weighed semi-dry noodles into noodle bundles in the shape of an "8"; the second sorting device 4 sorts and compresses the noodle bundles; the bagging device 5 packs the compressed noodle bundles into packaging bags.

[0046] The X direction shown in the figure is the first direction X.

[0047] The Y direction shown in the figure is the second direction Y.

[0048] The semi-dry noodles include whole noodles and loose noodles. The whole noodles are noodles with a weight close to the rated weight of the noodle bundle and can be directly sorted into noodle bundles. The loose noodles are noodles with an undetermined weight. The conveying device 1 includes a loose noodle conveyor belt 11 and a whole noodle conveyor belt 10. After the total weight of the loose noodles transported to the weighing device 2 reaches the rated weight of the noodle bundle, the loose noodle conveyor belt 11 stops transporting the loose noodles, and subsequent other devices (the first sorting device 3, the second sorting device 4, and the bagging device 5) will sort the loose noodles on the weighing device 2 into noodle bundles for packaging.

[0049] The number of the weighing device 2 and the first sorting device 3 can both be two, and the loose noodle conveyor belt 11 and the whole noodle conveyor belt 10 each correspond to one weighing device 2 and one first sorting device 3.

[0050] The number of noodle bundles required for the packaged finished product can be one or more. When the number of noodle bundles is one, the noodle bundle is made by the loose noodle conveyor belt 11, and the weighing device 2 corresponding to the loose noodle conveyor belt 11 weighs the weight of the loose noodles to make the weight of the made noodle bundle meet the weight standard of the finished product; when the number of noodle bundles is multiple, for example, the number of noodle bundles is four, three of the noodle bundles are first provided by the whole noodle conveyor belt 10, the weighing device 2 corresponding to the whole noodle conveyor belt 10 weighs and records the weight of these three noodle bundles, and the loose noodle weighing device 2 corresponding to the loose noodle conveyor belt 11 determines the weight of the noodle bundle provided by the loose noodle conveyor belt 11 according to the total weight of the three noodle bundles made first, so as to ensure that the weight of the finished product containing four noodle bundles meets the production standard.

[0051] The packaging machine includes a conveying device 1, a weighing device 2, a first sorting device 3, a second sorting device 4, and a bagging device 5, which can realize the weighing, sorting, and bagging of semi-dry noodles, ensuring both the neatness of the noodles and the weighing and packaging. This mechanized assembly line production has high metering accuracy, high efficiency, saves materials, and reduces labor costs at the same time.

[0052] The packaging machine provided by this application is relatively miniaturized, and the whole body is decorated with all-stainless steel, which is corrosion-resistant and easy to clean.

[0053] Optionally, as Figures 3 - 5 shown, the first sorting device 3 includes a support plate 30, a traction hook 31, a first driving component 32 and a first pushing member 33; the support plate 30 includes a sorting area for placing semi-dry noodles; the traction hook 31 hooks the middle part of the semi-dry noodles; the first driving component 32 is connected to the traction hook 31 and drives the traction hook 31 to move along the first direction X, so that the semi-dry noodles are bent into a U shape, and the semi-dry noodles are pulled to the sorting area for sorting; the first pushing member 33 is arranged on the support plate 30 and pushes the semi-dry noodles away from the sorting area along the second direction Y.

[0054] The traction hook 31 can be an L-shaped structure.

[0055] The semi-dry noodles fall from the end of the conveying device 1 onto the weighing device 2. After weighing, the traction hook 31 hooks the middle part of the semi-dry noodles and moves along the first direction X towards the support plate 30. The two ends of the semi-dry noodles move towards the opposite direction of the moving direction along with the movement of the traction hook 31 and are bent into a U shape. The semi-dry noodles move to the sorting area and are sorted into an 8 shape, reducing the probability of the noodle bundle in the packaging bag being scattered and facilitating consumers to pick up. The first pushing member 33 pushes the sorted noodle bundle away from the sorting area and makes it enter the second sorting device 4. The sorting process of the semi-dry noodles is continuous, fast, and has high processing efficiency.

[0056] Optionally, as Figures 3 - 5 shown, the first driving component 32 includes a first driving member 321, a second driving member 322 and a third driving member 323; the first driving member 321 drives the traction hook 31 to move along the first direction X, so that the semi-dry noodles are bent into a U shape; the second driving member 322 drives the traction hook 31 to rotate along the first direction X to sort the semi-dry noodles into an 8 shape; the third driving member 323 drives the traction hook 31 to move along the third direction Z away from the support plate 30 to disengage from the semi-dry noodles. The first direction X, the second direction Y and the third direction Z are perpendicular to each other pairwise.

[0057] The Z direction shown in the figure is the third direction Z.

[0058] The first driving member 321 drives the towing hook 31 to pull the weighed semi-dry noodles away from the weighing device 2 and pull them to the sorting area. Then, the second driving member 322 drives the towing hook 31 to rotate along the first direction X, and the U-shaped semi-dry noodles rotate with the rotation of the towing hook 31 and are wound into a continuous figure-eight shape. The third driving member 323 drives the towing hook 31 to move along the third direction Z. The folding edge of the rotated towing hook 31 faces the support plate 30 along the first direction X, and the noodle bundle stays in the sorting area under the action of its own weight. The towing hook 31 is disengaged from the noodle bundle to avoid the movement path of the first pushing member 33, enabling the processing process to proceed continuously.

[0059] Optionally, as Figure 3 shown, the support plate 30 is further provided with a first avoidance groove 300, and the towing hook 31 extends into the first avoidance groove 300 when it is flipped under the drive of the second driving member 322.

[0060] The first avoidance groove 300 is provided on the side of the support plate 30 facing away from the first pushing member 33.

[0061] When the towing hook 31 rotates under the drive of the second driving member 322, it extends into the first avoidance groove 300, and the spacing distance between the towing hook 31 and the support plate 30 in the third direction Z is relatively short, enabling the semi-dry noodles to be placed on the support plate 30 during the rotation process and reducing the risk of the semi-dry noodles falling off the towing hook 31 during the rotation process.

[0062] Optionally, as Figure 3 、 Figures 5 - 7 shown, the weighing device 2 includes a weighing member 20 and a sensor 21. The weighing member 20 includes a connecting edge 201 and a supporting edge 202. The two supporting edges 202 are arranged opposite to each other along the second direction Y, and the connecting edge 201 connects the two supporting edges 202. The connecting edge 201 and the two supporting edges 202 enclose a space for accommodating the towing hook 31, and the sensor 21 is used to measure the weight of the semi-dry noodles conveyed by the conveying device 1 to the weighing member 20.

[0063] The weighing member 20 can be an L-shaped structure adapted to the outer shape of the towing hook 31.

[0064] During the weighing process, the towing hook 31 is located inside the space enclosed by the connecting edge 201 and the two supporting edges 202. The two supporting edges 202 support the middle part of the semi-dry noodles, and the sensor 21 measures the weight of the semi-dry noodles hanging on the weighing member 20. After weighing is completed, the towing hook 31 moves along the first direction X, passes through between the two connecting edges 201 and takes away the noodles hanging on the two connecting edges 201. The support device provided in the present application can timely record the weight of the noodle bundle, facilitate the adjustment of the weight of the finished product, make the weighed weight within the rated range, and improve the production efficiency of the finished product while enhancing the accuracy of the weight of the finished product.

[0065] Optionally, asFigures 8 - 10 As shown in the figure, the second sorting device 4 includes a frame 40, a fifth driving member 41, a material box 42 and a second driving assembly 43; the frame 40 includes a first frame 401, a second frame 402 and a fourth driving member 400, the second frame 402 is rotatably connected to the first frame 401, and the fourth driving member 400 drives the second frame 402 to rotate around the first direction X as the axis; the fifth driving member 41 is connected to the first frame 401 and drives the frame 40 to move along the third direction Z, and the first direction X, the second direction Y and the third direction Z are perpendicular to each other in pairs; the material box 42 is arranged on the second frame 402; the second driving assembly 43 drives the material box 42 to deform to sort and press the noodle bundle.

[0066] The material box 42 rotates synchronously with the second frame 402 around the first direction X as the axis.

[0067] The second frame 402 rotates under the drive of the fourth driving member 400, and the material box 42 rotates with the rotation of the second frame 402. When the material box 42 receives the noodle bundle, the length direction of the material box 42 is parallel to the second direction Y. Along the second direction Y, a part of the material box 42 and the support plate 30 that is away from the first pushing member 33 overlap, so that the noodle bundle can fall into the material box 42. The fifth driving member 41 drives the material box 42 to move along the third direction Z towards the support plate 30, shortening the falling distance of the noodle bundle and reducing the risk of damage to the noodles due to falling; when the material box 42 sends the sorted noodle bundle for bagging, the direction of the material box 42 is parallel to the third direction Z, and the opening of the material box 42 facing away from the support plate 30 is directly opposite to the opening of the packaging bag. The noodle bundle in the material box 42 can slide towards the packaging bag under the action of gravity. The fifth driving member 41 drives the material box 42 to move along the third direction Z away from the support plate 30, shortening the distance between the material box 42 and the packaging bag and reducing the risk of the noodle bundle in the material box 42 falling to the outside.

[0068] Optionally, as Figures 9 - 10 shown, the material box 42 includes a first structural member 421 and a second structural member 422; the first structural member 421 includes a first side 4210 and a second side 4211, and the first side 4210 is perpendicular to the second side 4211; the second structural member 422 includes a third side 4220 and a fourth side 4221, and the third side 4220 is perpendicular to the fourth side 4221; the first side 4210 and the third side 4220 are arranged opposite to each other along the first direction X, the second side 4211 and the fourth side 4221 are stacked, and the second driving assembly 43 includes a sixth driving member 430, and the sixth driving member 430 drives the second connecting member to move along the second direction Y to press the semi-dry noodles placed on the second side 4211.

[0069] When the noodle box 42 receives the noodle bundle, the second side 4211 is closer to the support part than the fourth side 4221. The second side 4211 blocks a part of the fourth side 4221. Most of the noodle bundle falling from the support plate 30 is located on the second side 4211. After the noodle bundle is received, the sixth driving member 430 drives the second connecting member to move along the second direction Y, so that the distance between the first side 4210 and the third side 4220 is shortened. The part of the noodle bundle located on the fourth side 4221 is pushed by the third side 4220 to move towards the second side 4211. The blocking area of the second side 4211 for the fourth side 4221 gradually increases until the second side 4211 completely blocks the fourth side 4221, making the noodle bundle neatly arranged on the second side 4211 and reducing the risk of bending and breaking when the noodle bundle enters the packaging bag.

[0070] Optionally, as Figure 10 shown, the noodle box 42 further includes a third structural member 423. The third structural member 423 includes a fifth side 4230 and two sixth sides 4231. The two sixth sides 4231 are arranged oppositely along the first direction X. The fifth side 4230 connects the two sixth sides 4231. Along the first direction X, the first side 4210 and the third side 4220 are located between the two sixth sides 4231. The first side 4210, the second side 4211, the third side 4220 and the fifth side 4230 enclose a space for pressing the noodle bundle; the second driving assembly 43 further includes a seventh driving member 431. The seventh driving member 431 drives the third structural member 423 to approach or move away from the first structural member 421.

[0071] When the noodle box 42 receives the noodle bundle, the third structural member 423 moves away from the first structural member 421 along the third direction Z, reducing the probability of blocking the second side 4211. After the noodle bundle is received and neatly arranged under the push of the second structural member 422, the third structural member 423 moves towards the first structural member 421 under the drive of the seventh driving member 431. The fifth side 4230 and the second side 4211 squeeze the noodle bundle along the third direction Z, reducing the gap between the semi-dry noodles, making them fit together, not easily deformed, and reducing the overall volume of the noodle bundle, which is convenient for entering the packaging bag.

[0072] Optionally, as Figures 3 - 4 shown, the second sorting device 4 further includes a second pushing member 44. The second pushing member 44 is used to push the noodle bundle in the noodle box 42 along the third direction Z. The first direction X, the second direction Y and the third direction Z are perpendicular to each other in pairs.

[0073] When the noodle box 42 sends out the noodle bundle towards the packaging bag, the output end of the second pushing member 44 can extend into the noodle box 42 and push the noodle bundle in the noodle box 42 along the first direction X, reducing the probability of the noodles sticking to the inner wall of the noodle box 42.

[0074] Optionally, as Figure 11As shown, the bagging device 5 includes a jaw 50, a suction cup 51, and an eighth driving member 52; the jaw 50 is used to clamp the packaging bag; the suction cup 51 adsorbs one side of the opening of the packaging bag; the eighth driving member 52 drives the suction cup 51 to move in a direction away from the packaging bag to open the packaging bag.

[0075] The bagging device 5 further includes a movable assembly and a sealing assembly. The movable assembly can send a new packaging bag to the jaw 50 and send the bagged packaging bag to the sealing assembly for sealing.

[0076] Before the bagging operation, the jaw 50 clamps the packaging bag, the suction cup 51 adsorbs one side of the opening of the packaging bag, and under the drive of the eighth driving member 52, it moves in the second direction Y in a direction away from the packaging bag to open the opening of the packaging bag, facilitating the entry of the noodle bundle.

[0077] Although the present application has been described with reference to the preferred embodiments, various improvements can be made to it and components therein can be replaced with equivalents without departing from the scope of the present application. In particular, as long as there is no structural conflict, the various technical features mentioned in each embodiment can be combined in any way. The present application is not limited to the specific embodiments disclosed in the text but includes all technical solutions falling within the scope of the claims.
