Description

Technical Field

[0001] This application belongs to the field of packaging equipment technology, and more specifically it relates to a fully automatic food bagging machine. Background Technology

[0002] After food and other products are produced, they need to be bagged and packaged to facilitate subsequent transportation and storage.

[0003] Currently, Chinese patent CN208119530U discloses a utility model patent entitled "A Food Bagging Machine," which includes a bag-feeding conveyor mechanism, a pushing mechanism, a bag-suction mechanism, a bag-supporting mechanism, and a discharge conveyor mechanism. The pushing mechanism and the bag-suction mechanism are installed above the bag-feeding conveyor mechanism, and the bag-supporting mechanism is installed to the left of the bag-feeding conveyor mechanism. A pre-set packaging bag is placed above the bag-supporting mechanism, and the discharge conveyor mechanism is installed to the left of the bag-supporting mechanism. Compared to manual bagging, the bag-feeding conveyor mechanism drives the food to the pushing station, the bag-suction mechanism sucks up and opens the packaging bag opening, the pushing mechanism pushes the food through the packaging bag opening into the inner cavity of the packaging bag, and the discharge conveyor mechanism drives the packaging bag containing food to the next station. This method features a high degree of automation, fast bagging speed, and saves manpower and resources.

[0004] Existing food bagging machines similar to those described above may have the following drawbacks in actual use: materials are conveyed directly via a conveyor belt, resulting in inconsistent spacing between food items, which may lead to overfilling or underfilling during bagging; after the food is bagged, it is difficult to seal the packaging bag in a timely manner, which may cause food spillage during subsequent conveying. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a fully automatic food bagging machine, which has the advantages of avoiding problems such as inconsistent spacing between food items, over-packing or under-packing during bagging, and food spillage during subsequent conveying.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fully automatic food bagging machine, including a workbench, a food conveying mechanism is provided on the top of the workbench, the food conveying mechanism is used to convey food, and a pushing mechanism is provided at the tail end of the food conveying mechanism in the conveying direction;

[0007] The food conveying mechanism is provided with an empty packaging bag stacking platform on its side, and an empty bag gripping mechanism that can move horizontally is provided above the empty packaging bag stacking platform. The empty bag gripping mechanism is used to grip the empty packaging bags stacked on the empty packaging bag stacking platform.

[0008] The side of the empty packaging bag stack is provided with a second transmission belt parallel to the food conveying mechanism, and the pushing mechanism pushes the items on the food conveying mechanism toward the second transmission belt.

[0009] A bag opening mechanism and a bag supporting mechanism are respectively provided above the second transmission belt and in a position colinear with the longitudinal direction of the pushing mechanism. The bag opening mechanism is located directly above the second transmission belt to open the bag opening, and the bag supporting mechanism is located on the side of the second transmission belt to support the bag opening.

[0010] The tail end of the second transmission belt is provided with a sealing mechanism, which seals the opening of the packaged bag after packaging.

[0011] The food conveying mechanism includes a first driving device, a first conveyor belt is mounted on the drive shaft of the first driving device, and partition plates are equidistantly arranged on the outer surface of the first conveyor belt for separating items.

[0012] The workbench is also equipped with a human-machine interface device. The food conveying mechanism, pushing mechanism, empty packaging bag stacking platform, empty bag gripping mechanism, second transmission belt, bag opening mechanism, bag supporting mechanism, and bag sealing mechanism are all connected to the human-machine interface device via signal.

[0013] By adopting the above technical solution, the object to be packaged can be placed on the surface of the first conveyor belt and separated at equal intervals by the partition plate, and moved towards the pushing mechanism by the drive of the first driving device.

[0014] At the same time, the empty bag grabbing mechanism grabs the empty bags stacked on the empty packaging bag stack and places the empty bags on the second transmission belt. The empty bags are then transported to a position collinear with the pushing mechanism via the second transmission belt. The bag opening mechanism first lowers to adsorb the upper layer of the packaging bag opening, and then rises to open the opening of the packaging bag. Subsequently, the bag supporting mechanism moves to the inside of the packaging bag to support the opening of the packaging bag.

[0015] After the object moves to the position of the pushing mechanism, the pushing mechanism pushes the object in the partition plate into the already opened packaging bag for bagging by moving horizontally. After bagging is completed, the bag opening mechanism, bag opening mechanism and pushing mechanism all return to the initial position, waiting for the next bagging. The bagged object continues to be conveyed to the bottom of the sealing mechanism by the second transmission belt. The sealing mechanism seals the mouth of the packaging bag to complete the entire bagging operation.

[0016] The entire equipment completes the bagging and sealing operations in a cyclical manner according to the settings of the human-machine interaction device.

[0017] In a preferred embodiment: baffles are provided at both ends of the first conveyor belt, and the baffles have openings at the material pushing mechanism.

[0018] By adopting the above technical solution, when items are placed on the surface of the first conveyor belt, the baffle can prevent items from falling off the side of the first conveyor belt, thus improving the stability of item transmission. The baffle has an opening at the location of the pushing mechanism to avoid obstructing the pushing mechanism from pushing the items into the bag. The width of the opening is equal to the distance between two adjacent partitions, preventing the opening from being too small so that the pushing mechanism cannot fully push the items into the packaging bag, or too large so that the items fall off.

[0019] In a preferred embodiment: the pushing mechanism includes a longitudinal guide rail that spans the top of the food conveying mechanism; a second driving device is provided on the side of the longitudinal guide rail; a longitudinal slider that can translate along the longitudinal guide rail is provided on the longitudinal guide rail; the longitudinal slider is driven to move by the second driving device; a push rod is provided at the bottom of the longitudinal slider; a pushing plate is provided at the end of the push rod; the pushing plate can move from the outer side of the food conveying mechanism to the top of the second transmission belt.

[0020] By adopting the above technical solution, when the item is in a position that overlaps longitudinally with the pushing mechanism, the second driving device drives the longitudinal slider to slide along the track of the longitudinal guide rail, thereby pushing the item in the partition plate towards the direction of the second transmission belt through the pushing plate at the end of the push rod, thereby realizing the bagging action.

[0021] In a preferred embodiment: the empty bag gripping mechanism includes a horizontal driver, and a chain track is provided on the side of the horizontal driver, the chain track being in communication with the horizontal driver;

[0022] The horizontal drive is equipped with a first lifter, and the bottom of the first lifter is equipped with a gripping suction cup. The horizontal drive can drive the gripping suction cup to move from the top of the empty packaging bag stack to the top of the second transmission belt.

[0023] By adopting the above technical solution, the horizontal driver can drive the gripping suction cup to move horizontally along the transmission direction of the second transmission belt, thereby positioning the gripping suction cup above the empty packaging bag stack or above the second transmission belt. When the gripping suction cup is above the empty packaging bag stack, the first lifter drives the gripping suction cup to descend and grips the packaging bag under the action of vacuum suction. Then, the gripping suction cup transports the packaging bag to the top of the second transmission belt and places the packaging bag on the second transmission belt, which then transports the packaging bag.

[0024] In a preferred embodiment: the bag opening mechanism includes a second lifter, the bottom of the second lifter is provided with a connecting frame, the bottom of the connecting frame is provided with a bag opening suction cup, and the bag opening suction cup is located at the opening of the packaging bag.

[0025] By adopting the above technical solution, when the packaging bag is directly below the opening suction cup, the second lifting device drives the connecting frame to lower the opening suction cup. After the opening suction cup adsorbs the upper part of the bag opening through vacuum suction, the second lifting device rises to open the bag opening, so as to cooperate with the pushing mechanism to bag the items.

[0026] In a preferred embodiment: the bottom of the first lifting device is provided with a bracket for mounting a gripping suction cup, the bracket is provided with an elliptical mounting groove, the gripping suction cup is installed in the elliptical mounting groove, and the gripping suction cup can be adjusted in position.

[0027] By adopting the above technical solution, the installation position of the gripping suction cup can be adjusted according to the size of the packaging bag, so that the position of the gripping suction cup can be adapted to more sizes and models of packaging bags, enabling the gripping suction cup to more stably adsorb and grip the packaging bag, and improving adaptability.

[0028] In a preferred embodiment: the connecting frame is also provided with an elliptical mounting groove, the bag opening suction cup is installed in the elliptical mounting groove, and the bag opening suction cup can be adjusted in position.

[0029] By adopting the above technical solution, the suction cup for opening bags can be adjusted in position according to the different sizes of the packaging bags, so that when opening the bag, the suction cup can more accurately and stably adhere to the opening of the packaging bag, reducing the possibility of opening errors.

[0030] In a preferred embodiment: the bag-supporting mechanism includes a longitudinal pusher, a bag-supporting platform is provided at the bottom of the longitudinal pusher, the longitudinal pusher can drive the bag-supporting platform to move towards the packaging bag, a third driving device is provided on the side of the bag-supporting platform, a bag-supporting slider is provided at the bottom of the bag-supporting platform, a bag-supporting device is provided at the bottom of the bag-supporting slider, the third driving device is used to drive the bag-supporting slider to move horizontally, and the bag-supporting slider drives the bag-supporting device to open the opening of the packaging bag.

[0031] By adopting the above technical solution, after the opening of the packaging bag is opened by the bag opening mechanism, in order to maintain the shape and stability of the bag opening, the longitudinal pusher will drive the bag-supporting platform to insert into the packaging bag longitudinally, and then the third drive device will drive the bag-supporting slider to move horizontally, so as to drive the bag supporter to move to both sides of the packaging bag, thereby making the bag opening of the packaging bag fully open, so as to facilitate the pusher mechanism to push the item into the packaging bag, and avoid the packaging bag opening not being fully opened, which would result in the item not being able to be completely packaged.

[0032] In a preferred embodiment: the sealing mechanism includes a first telescopic rod, which is disposed at the upper end of the tail of the second transmission belt in the conveying direction, and a sealing pressure plate is disposed at the lower end of the first telescopic rod. The first telescopic rod is used to drive the sealing pressure plate to apply pressure to the bag opening of the packaging bag.

[0033] A bag opening support plate is provided directly below the side sealing pressure plate of the second transmission belt, and the bag opening support plate supports the bag opening from the bottom of the packaging bag.

[0034] By adopting the above technical solution, after the items are bagged, they will continue to be driven backward by the second transmission belt. At this time, the first telescopic rod will drive the sealing pressure plate to descend and apply pressure to the bag opening of the packaging bag located below the sealing pressure plate. In conjunction with the bag opening support plate, the bag opening will be sealed under the action of pressure and / or heat, preventing the items from leaking out of the packaging bag during the transmission process and improving the working efficiency of the bagging machine.

[0035] In a preferred embodiment: a food sorting mechanism is provided above the food conveying mechanism. The food sorting mechanism includes a second telescopic rod, and a leveling plate is provided at the bottom of the second telescopic rod. The second telescopic rod can drive the leveling plate to apply pressure to the items in the partition plate.

[0036] The second telescopic rod is connected to the human-machine interaction device via signal.

[0037] By adopting the above technical solution, during the process of transporting items in the partition, the second telescopic rod will drive the leveling pressure plate to descend and apply slight pressure to the objects located in the partition, so that the items can be laid flat between the two partitions under the pressure, avoiding the items from being piled up too high and unable to be bagged smoothly, and reducing the bagging error rate.

[0038] Compared with the prior art, this application has the following beneficial effects:

[0039] 1. By setting a separator on the first conveyor belt, the separator can separate the objects conveyed on the first conveyor belt at equal intervals, preventing the objects from piling up together or the distance between the objects from being too large, thus avoiding the problem of over-packing or missing items when bagging, thereby improving the accuracy of bagging.

[0040] 2. By setting a first telescopic rod at the end of the second transmission belt in the conveying direction, the sealing pressure plate is driven to move up and down. After the object is bagged, it is transmitted to the bottom of the sealing pressure plate via the second transmission belt. At this time, the sealing pressure plate presses down and cooperates with the bag mouth support plate to seal the packaging bag, so as to avoid leakage of the goods and improve packaging efficiency.

[0041] 3. By setting a second telescopic rod above the first conveyor belt to drive the leveling pressure plate to rise and fall, the leveling pressure plate can apply pressure to the objects in the partition plate, so that the objects in the partition plate are laid flat between the two partition plates. At the same time, it avoids the objects from piling up too high and being unable to be bagged smoothly.

[0042] 4. The longitudinal pusher drives the bag-holding platform to be inserted into the packaging bag. Then, the third drive device drives the bag-holding slider to move horizontally, so as to move the bag-holding device to both sides of the packaging bag, thereby fully opening the bag opening. This makes it easier for the items to be pushed into the packaging bag by the pushing mechanism, avoiding the situation where the bag opening is not fully opened, resulting in the items not being able to be completely packaged.

[0060] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings.

[0061] In the description of this disclosure, it should be understood that the terms "upper," "lower," "left," "right," "inner," "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the disclosed product is in use, or the orientation or positional relationship commonly understood by those skilled in the art. They are used only for the convenience of describing this disclosure and simplifying the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this disclosure.

[0062] A fully automatic food bagging machine, such as Figures 1-5 As shown, the device includes a workbench 1 that supports the entire unit. The workbench 1 contains devices for circuit control, power supply, and signal transmission. A food conveying mechanism 2 is located on the top of the workbench 1, used to convey food. A pushing mechanism 3 is located at the rear of the food conveying mechanism 2 in the conveying direction, used to push the conveyed food into the packaging bag, thus completing the bagging operation.

[0063] Meanwhile, an empty packaging bag stacking platform 4 is provided on the side of the food conveying mechanism 2, where empty packaging bags are stacked in batches for retrieval. The empty packaging bag stacking platform 4 is driven by pneumatic, hydraulic, or electric means and has a lifting function, gradually rising as the number of packaging bags decreases, ensuring the top of the stack remains at the same height. Above the empty packaging bag stacking platform 4 is a horizontally movable empty bag gripping mechanism 5. The empty bag gripping mechanism 5 uses vacuum suction to grip the stacked empty packaging bags on the empty packaging bag stacking platform 4.

[0064] A second transmission belt 6, parallel to the food conveying mechanism 2, is provided on the side of the empty packaging bag stack 4. Packaging bags grabbed by the empty bag gripping mechanism 5 are placed on the second transmission belt 6 and then conveyed by the second transmission belt 6 to merge with the items. The pushing mechanism 3 pushes the items on the food conveying mechanism 2 toward the second transmission belt 6 to transfer the position of the objects and realize the bagging action of the items.

[0065] Based on the above embodiment, a bag opening mechanism 7 and a bag supporting mechanism 8 are respectively arranged above the second transmission belt 6 and along the longitudinal direction of the pushing mechanism 3. The bag opening mechanism 7 is located directly above the second transmission belt 6 and is used to open the bag opening, allowing the item to enter the packaging bag. The bag supporting mechanism 8 is located on the side of the second transmission belt 6 and is used to support the bag opening, thereby maintaining the shape of the packaging bag opening to facilitate the entry of the object into the packaging bag.

[0066] Based on the above embodiments, a sealing mechanism 9 is provided at the tail end of the second transmission belt 6. The sealing mechanism 9 seals the opening of the packaged bag by pressure and heating to prevent leakage of the items and reduce the trouble of subsequent sealing, thereby improving efficiency.

[0067] Furthermore, to improve the accuracy of bagging, the food conveying mechanism 2 includes a first drive device 21, which is a torque-controllable drive device such as a servo motor or stepper motor. A first conveyor belt 22 is mounted on the drive shaft of the first drive device 21, so that the first conveyor belt 22 can be driven by the first drive device 21 to transport objects. Dividers 23 are evenly spaced on the outer surface of the first conveyor belt 22 to separate items or food at equal intervals, preventing items or food from being stacked together or spaced too far apart.

[0068] A human-machine interface device 10 is also installed on the workbench 1, and the human-machine interface device 10 is connected to the interior of the workbench 1 via wires. The food conveying mechanism 2, the pushing mechanism 3, the empty packaging bag stacking platform 4, the empty bag gripping mechanism 5, the second transmission belt 6, the bag opening mechanism 7, the bag supporting mechanism 8, and the bag sealing mechanism 9 are all signal-connected to the human-machine interface device 10. Through the human-machine interface device 10, the conveying speed of the food conveying mechanism 2 and the second transmission belt 6 can be set, the working interval of the pushing mechanism 3, the empty bag gripping mechanism 5, the bag opening mechanism 7, the bag supporting mechanism 8, and the bag sealing mechanism 9 can be set, and the rising speed of the empty packaging bag stacking platform 4 can be set. This allows the entire bagging machine to adapt to different production needs.

[0069] It should be noted that, as Figure 2 As shown, baffles are installed at both ends of the first conveyor belt 22, and the baffles have openings at the pushing mechanism 3. When items are placed on the surface of the first conveyor belt 22, the baffles prevent items from falling off the sides of the first conveyor belt 22, improving the stability of item transmission. The openings at the pushing mechanism 3 are designed to avoid obstructing the pushing mechanism 3 from pushing the items into the bag. The width of the opening is equal to the distance between two adjacent partition plates 23. This prevents the opening from being too small, preventing the pushing mechanism 3 from fully pushing the items into the packaging bag, or too large, causing the items to fall.

[0070] In one specific embodiment, such as Figure 1 and Figure 2 As shown, the feeding mechanism 3 includes a longitudinal guide rail 31 that spans the top of the food conveying mechanism 2. A second driving device 32 is provided on the side of the longitudinal guide rail 31. A longitudinal slider 33 that can be translated along the longitudinal guide rail 31 is provided on the longitudinal guide rail 31. The longitudinal slider 33 is driven to move by the second driving device 32. A push rod 34 is installed at the bottom of the longitudinal slider 33. A feeding plate 35 is provided at the end of the push rod 34. The feeding plate 35 can be moved from the outer side of the food conveying mechanism 2 to the top of the second transmission belt 6.

[0071] When the item is in a position that overlaps longitudinally with the pusher mechanism 3, the second drive device 32 drives the longitudinal slider 33 to slide along the track of the longitudinal guide rail 31, thereby pushing the item in the separator 23 toward the direction of the second transmission belt 6 through the pusher plate 35 at the end of the pusher rod 34, thus realizing the bagging action.

[0072] In one specific embodiment, such as Figure 1 , Figure 3 and Figure 5 As shown, the empty bag gripping mechanism 5 includes a horizontal driver 51, and a chain track 52 is mounted on the side of the horizontal driver 51. The chain track 52 is connected to the horizontal driver 51.

[0073] Based on the above embodiment, a first lifting device 53 is installed on the horizontal driver 51, and a gripping suction cup 54 is installed at the bottom of the first lifting device 53. The horizontal driver 51 can drive the gripping suction cup 54 to move from the top of the empty packaging bag stack 4 to the top of the second transmission belt 6. The horizontal driver 51 can drive the gripping suction cup 54 to move horizontally along the transmission direction of the second transmission belt 6, so that the gripping suction cup 54 is positioned above the empty packaging bag stack 4 or above the second transmission belt 6. When the gripping suction cup 54 is above the empty packaging bag stack 4, the first lifting device 53 drives the gripping suction cup 54 to descend and grip the packaging bag under the action of vacuum suction. Then, the packaging bag is transferred to the top of the second transmission belt 6 through the gripping suction cup 54 and placed on the second transmission belt 6 for transmission.

[0074] In one specific embodiment, such as Figure 3 and Figure 5 As shown, the bag opening mechanism 7 includes a second lifter 71, a connecting frame 72 at the bottom of the second lifter 71, and a bag opening suction cup 73 at the bottom of the connecting frame 72. The bag opening suction cup 73 is located at the opening of the packaging bag. When the packaging bag is directly below the bag opening suction cup 73, the second lifter 71 drives the connecting frame 72 to lower the bag opening suction cup 73. After the bag opening suction cup 73 adsorbs the upper part of the bag opening through vacuum suction, the second lifter 71 rises, thereby opening the bag opening to cooperate with the pushing mechanism 3 to bag the items.

[0075] Based on the above embodiments, such as Figure 3 As shown, the bottom of the first lifting device 53 is equipped with a bracket, and an elliptical mounting groove is opened on the bracket. The gripping suction cup 54 is installed in the elliptical mounting groove. In use, the installation position of the gripping suction cup 54 can be adjusted according to the size of the packaging bag, so that the position of the gripping suction cup 54 can be adapted to more sizes and models of packaging bags, so that the gripping suction cup 54 can more stably adsorb and grip the packaging bag, improving adaptability.

[0076] Specifically, in this embodiment, the connecting frame 72 is also provided with an elliptical mounting groove, in which the bag-opening suction cup 73 is installed. The bag-opening suction cup 73 can be adjusted in position according to the size of the packaging bag, that is, when opening the bag, the bag-opening suction cup 73 can more accurately and stably adhere to the opening of the packaging bag, reducing the possibility of bag-opening errors.

[0077] It is worth mentioning that, such as Figure 2 , Figure 3 and Figure 5 As shown, the bag-holding mechanism 8 includes a longitudinal pusher 81, a bag-holding platform 82 is provided at the bottom of the longitudinal pusher 81, the longitudinal pusher 81 can drive the bag-holding platform 82 to move towards the packaging bag, a third driving device 83 is provided on the side of the bag-holding platform 82, a bag-holding slider 84 is provided at the bottom of the bag-holding platform 82, and a bag-holding device 85 is provided at the bottom of the bag-holding slider 84. The third driving device 83 is used to drive the bag-holding slider 84 to move horizontally, and the bag-holding slider 84 drives the bag-holding device 85 to open the opening of the packaging bag.

[0078] After the opening of the packaging bag is opened by the opening mechanism 7, in order to maintain the shape and stability of the bag opening, the longitudinal pusher 81 will drive the bag-supporting platform 82 to insert into the packaging bag. Then, the third drive device 83 will drive the bag-supporting slider 84 to move horizontally, so as to drive the bag supporter 85 to move to both sides of the packaging bag, thereby making the bag opening fully open, so that the items can be pushed into the packaging bag by the pushing mechanism 3, and avoiding the bag opening not being fully opened, which would result in the items not being able to be completely packaged.

[0079] Based on the above embodiments, such as Figure 4 and Figure 5 As shown, the bag sealing mechanism 9 includes a first telescopic rod 91, which is located at the upper end of the tail of the second transmission belt 6 in the conveying direction. A sealing pressure plate 92 is provided at the lower end of the first telescopic rod 91. The first telescopic rod 91 is used to drive the sealing pressure plate 92 to apply pressure to the bag opening of the packaging bag. A bag opening support plate 93 is installed directly below the sealing pressure plate 92 on the side of the second transmission belt 6. The bag opening support plate 93 supports the bag opening from the bottom of the packaging bag.

[0080] After the items are bagged, they will continue to be driven backward via the second transmission belt 6. At this time, the first telescopic rod 91 will drive the sealing pressure plate 92 to descend and apply pressure to the bag opening of the packaging bag located below the sealing pressure plate 92. In conjunction with the bag opening support plate 93, the bag opening will be sealed under the action of pressure and / or heat, preventing the items from leaking out of the packaging bag during the transmission process and improving the working efficiency of the bagging machine.

[0081] It is worth mentioning that, such as Figure 3 As shown, a food sorting mechanism 11 is provided above the food conveying mechanism 2. The food sorting mechanism 11 includes a second telescopic rod 111. A leveling plate 112 is provided at the bottom of the second telescopic rod 111. The second telescopic rod 111 can drive the leveling plate 112 to apply pressure to the items in the partition plate 23. The second telescopic rod 111 is connected to the human-machine interaction device 10 via signal.

[0082] During the transfer of items in the partition 23, the second telescopic rod 111 will drive the leveling plate 112 to descend and apply slight pressure to the objects located in the partition 23, so that the items can be laid flat between the two partitions 23 under pressure, avoiding the items from being piled up too high and unable to be bagged smoothly, and reducing the bagging error rate.

[0083] It should be noted that the first lifting device 53, the second lifting device 71, the first telescopic rod 91 and the second telescopic rod 111 mentioned above are all one or a combination of devices with telescopic functions such as electric push rods, pneumatic push rods, and hydraulic push rods.

[0084] The working process and beneficial effects of this utility model are as follows:

[0085] During operation, the objects to be packaged can be placed on the surface of the first conveyor belt 22 and separated at equal intervals by the partition plate 23. Driven by the first drive device 21, they move towards the pushing mechanism 3, avoiding the problem of over-packing or missing packaging during bagging, thus improving the accuracy of bagging.

[0086] At the same time, the empty bag gripping mechanism 5 grips the empty bags stacked on the empty packaging bag stack 4 and places the empty bags on the second transmission belt 6. The empty bags are then transported to a position collinear with the pushing mechanism 3 via the second transmission belt 6. The bag opening mechanism 7 first lowers to adsorb the upper layer of the packaging bag opening, and then rises to open the opening of the packaging bag. Subsequently, the bag supporting mechanism 8 moves to the inside of the packaging bag to support the opening of the packaging bag, so as to avoid the packaging bag opening not being fully opened and the object not being able to be completely packaged.

[0087] During the process of the object moving to the position of the pushing mechanism 3, the second telescopic rod 111 drives the leveling plate 112 to rise and fall. The leveling plate 112 applies pressure to the object in the partition plate 23, so that the object in the partition plate 23 is laid flat between the two partition plates 23, avoiding the object from piling up too high and being unable to be bagged smoothly.

[0088] When the object moves to the position of the pushing mechanism 3, the pushing mechanism 3 pushes the object in the partition plate 23 into the already opened packaging bag by moving horizontally. After the bag is filled, the opening mechanism 7, the supporting mechanism 8 and the pushing mechanism 3 all return to their initial positions and wait for the next bag filling. The bagged object continues to be conveyed to the bottom of the sealing mechanism 9 by the second transmission belt 6. The sealing mechanism 9 seals the opening of the packaging bag to prevent leakage of the goods and completes the entire bag filling operation.

[0089] The entire equipment completes the bagging and sealing operations in a cyclical manner according to the settings of the human-machine interaction device 10.

[0090] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
