[0002] The bag - loading and packing mechanism of a flat - pushing bag - feeding packaging machine is the core part of the packaging process. It can transport bags, accurately load materials into the bags, and perform subsequent processes such as sealing. The bag - loading and packing mechanism usually includes multiple key components such as a bag - transporting mechanism, a bag - opening mechanism, and a bag - loading mechanism, which work together to complete the bag - loading and packing task.

[0003] In the bag - loading and packing mechanism of a flat - pushing bag - feeding packaging machine in related technologies, an independent bag - opening mechanism is required to open the bag mouth. The existence of the bag - opening mechanism increases the cost of the flat - pushing bag - feeding packaging machine, and after the bag is loaded with materials, the bag is usually evacuated and the bag mouth is sealed manually, resulting in low production efficiency.

[0038] The bagging and packing mechanism of the flat-pushing type bag-feeding packaging machine is the core part of the packaging process. It can transport bags, accurately load materials into the bags, and perform subsequent processes such as sealing. The bagging and packing mechanism generally includes multiple key components such as a bag transporting mechanism, a bag opening mechanism, and a bag loading mechanism, which work together to complete the task of bagging and packing.

[0039] For the bagging and packing mechanism of the flat-pushing type bag-feeding packaging machine in the related art, it is necessary to set up an independent bag opening mechanism to open the bag mouth. Due to the existence of the bag opening mechanism, the cost of the flat-pushing type bag-feeding packaging machine increases, and after the bag is loaded with materials, it is usually manually used to evacuate the air in the bag and seal the bag mouth, resulting in low production efficiency.

[0040] Based on this, to improve the problems in the related art that the need to independently set up a bag opening mechanism leads to increased costs, and the low efficiency of manually evacuating the air in the bag and sealing the bag mouth, the embodiments of this application provide the following solutions.

[0041] Please refer to Figure 1 and Figure 2 , the embodiments of this application provide a bagging and packing mechanism 100, which is applied to a flat-pushing type bag-feeding packaging machine 1000. The flat-pushing type bag-feeding packaging machine 1000 includes a machine shell 1100 and multiple transporting devices 1200. The machine shell 1100 has a machine shell accommodating space. The bagging and packing mechanism 100 is used to be arranged in the machine shell accommodating space. Part of the transporting device 1200 is located in the machine shell accommodating space, and is used to transport packaging bags or materials to the bagging and packing mechanism 100, or receive the packaging bags filled with materials output by the bagging and packing mechanism 100 to move the packaging bags filled with materials away from the bagging and packing mechanism 100; the bagging and packing mechanism 100 includes a mounting plate 10, a bag feeding device 20, a bag loading device 30, and a packing device 40, wherein:

[0042] The mounting plate 10 is used to be set on the casing 1100 and located within the accommodation space of the casing.

[0043] The bag feeding device 20 is set on the mounting plate 10. The bag feeding device 20 includes an upper suction and transfer device 22 and a lower suction and transfer device 23 which are oppositely arranged. The upper suction and transfer device 22 is used to adsorb one side of the packaging bag and convey the packaging bag, and the lower suction and transfer device 23 is used to adsorb the other side of the packaging bag and convey the packaging bag; the conveying direction of the packaging bag of the lower suction and transfer device 23 is inclined to the conveying direction of the packaging bag of the upper suction and transfer device 22 so that a tapered gap is formed between the upper suction and transfer device 22 and the lower suction and transfer device 23, so that while the packaging bag is moved from the narrow end of the tapered gap to the wide end of the tapered gap by the upper suction and transfer device 22 and the lower suction and transfer device 23, the bag opening can be automatically opened; wherein, the opening size of the narrow end of the tapered gap is smaller than the opening size of the wide end of the tapered gap.

[0044] The bagging device 30 is set on the mounting plate 10 and located on the output side of the bag feeding device 20, and is used to receive the packaging bag output by the bag feeding device 20, and convey the material to be packaged in the packaging bag and then extract the air in the packaging bag to form a vacuum environment.

[0045] The packing device 40 is set on the mounting plate 10 and located on the output side of the bagging device 30, and is used to receive the packaging bag containing the material output by the bagging device 30 and seal the packaging bag containing the material after vacuum extraction.

[0046] It can be understood that the mounting plate 10 is a plate-like structure and can play a role in support and fixation. For example, the mounting plate 10 can be a copper plate or an aluminum plate, etc., but not limited thereto.

[0047] The bag feeding device 20 is a device that can suck the packaging bag on the conveying device 1200 and move the packaging bag to the bagging device 30. The upper suction and transfer device 22 is a device that can adsorb the packaging bag and move the packaging bag close to the bagging device 30. For example, the upper suction and transfer device 22 can include a suction device and a moving device for driving the suction device to move. The suction device can be a corrugated suction cup, a multi-point vacuum suction cup, etc., but not limited thereto. The moving device can be a driving cylinder, a driving motor, etc., but not limited thereto. The lower suction and transfer device 23 is a device that can adsorb the packaging bag and move the packaging bag close to the bagging device 30. For example, the lower suction and transfer device 23 can include a suction device and a moving device for driving the suction device to move. The suction device can be a corrugated suction cup, a multi-point vacuum suction cup, etc., but not limited thereto. The moving device can be a driving cylinder, a driving motor, etc., but not limited thereto. The narrow end of the tapered gap refers to the place where the distance between the upper suction and transfer device 22 and the lower suction and transfer device 23 is the shortest along the gravity direction, and the wide end of the tapered gap refers to the place where the distance between the upper suction and transfer device 22 and the lower suction and transfer device 23 is the longest along the gravity direction. The lower suction and transfer device 23 can be located directly below the upper suction and transfer device 22.

[0048] The bagging device 30 is a device that can receive the packaging bags output by the bag feeding device 20, move the material into the packaging bags, then move the material with the packaging bags to the packing device 40, and evacuate the air in the packaging bags while moving the material with the packaging bags to the packing device 40. For example, the bagging device 30 may include a suction device, a moving device for driving the suction device to move, and a vacuum push rod that can move the material into the packaging bag and evacuate the air in the packaging bag. The suction device may be a corrugated suction cup, a multi-point vacuum suction cup, etc., but is not limited thereto. The moving device may be a driving cylinder, a driving motor, etc., but is not limited thereto. The vacuum push rod may include a hollow rod and an air extraction device capable of extracting the air in the inner channel of the hollow rod. For example, the hollow rod may be a plastic rod, an aluminum rod, etc., but is not limited thereto. The air extraction device may be an electric vacuum compression bag air extraction pump, a small rotary vane vacuum pump, etc., but is not limited thereto.

[0049] The packing device 40 is a device that can receive the packaging bags with materials output by the bagging device 30 and seal the bag mouths of the packaging bags. For example, the packing device 40 may include a sealing machine capable of sealing the packaging bags and a conveying device capable of transporting the packaging bags to the sealing machine and outputting the packaging bags after being sealed by the sealing machine. For example, the sealing machine may be a full-automatic rolling sealing machine, a heat sealing machine, etc., but is not limited thereto. The conveying device may be a roller conveyor, a chain conveyor, etc., but is not limited thereto, etc., but is not limited thereto.

[0050] As can be seen from the above, for the bagging and packing mechanism 100 provided by the embodiment of the present application, through the bag feeding device 20 arranged on the mounting plate 10, during the process of the packaging bag being transported by the bag feeding device 20 to the bagging device 30, the bag mouth of the packaging bag can be automatically opened by the action of the mutually inclined transportation directions of the upper suction and transfer device 22 and the lower suction and transfer device 23 of the bag feeding device 20, so that the flat-push type bag feeding packaging machine 1000 does not need to additionally set up an independent bag opening mechanism to open the bag mouth, reducing the cost of the flat-push type bag feeding packaging machine 1000; then, after the bagging device 30 arranged on the mounting plate 10 and capable of partially being located between the upper suction and transfer device 22 and the lower suction and transfer device 23 of the bag feeding device 20 receives the packaging bag transported by the bag feeding device 20, it pushes the material into the packaging bag, moves the packaging bag with the material to the packing device 40, and continuously evacuates the air in the packaging bag during the process of moving the packaging bag with the material to the packing device 40; finally, the packing device 40 arranged on the mounting plate 10 completes the sealing operation of the packaging bag while the bagging device 30 evacuates the air in the packaging bag, improving the technical problem of low efficiency in manually evacuating the air in the bag and sealing the bag mouth.

[0051] In some embodiments, please refer to Figure 3 and Figure 4, the bag feeding device 20 further includes a bag feeding fixing plate 21 and a bag sucking device 24.

[0052] The bag feeding fixing plate 21 is arranged on the mounting plate 10 and is used for fixing the bag feeding device 20.

[0053] The bag sucking device 24 is arranged on the bag feeding fixing plate 21 and is located above the upper bag sucking and conveying device 22, and is used for sucking and moving the packaging bag so that one side of the packaging bag contacts the upper bag sucking and conveying device 22.

[0054] Wherein, the upper bag sucking and conveying device 22 is arranged on the bag feeding fixing plate 21; the lower bag sucking and conveying device 23 is arranged on the bag feeding fixing plate 21 and is located below the upper bag sucking and conveying device 22; the length of the upper bag sucking and conveying device 22 is greater than the length of the lower bag sucking and conveying device 23 so that the packaging bag will not contact the lower bag sucking and conveying device 23 during the process of the bag sucking device 24 moving the packaging bag, the bag sucking device 24 is located on one side of the narrow end of the conical gap, and the bag sucking device 24 is located on the side of the lower bag sucking and conveying device 23 away from the bag filling device 30.

[0055] It can be understood that the bag feeding fixing plate 21 is a plate-like structure and can play a role in supporting and fixing. For example, the bag feeding fixing plate 21 can be a copper plate or an aluminum plate, etc., but is not limited thereto.

[0056] The length of the upper bag sucking and conveying device 22 in the transportation direction of the packaging bag can be greater than the length of the lower bag sucking and conveying device 23 in the transportation direction of the packaging bag. The bag sucking device 24 is a device that can suck and move the packaging bag so that one side of the packaging bag contacts the upper bag sucking and conveying device 22. For example, the bag sucking device 24 can include a bag sucking moving part, at least one suction nozzle, etc., but is not limited thereto. Among them, the suction nozzle is connected to the power output end of the bag sucking moving part, and the bag sucking moving part is a device that can drive the suction nozzle to approach or move away from the upper bag sucking and conveying device 22. For example, the bag sucking moving part can be a driving motor, a driving cylinder, etc., but is not limited thereto. The suction nozzle is a device that can adsorb or not adsorb the packaging bag. For example, the suction nozzle can be a vacuum suction nozzle, an electrostatic suction nozzle, etc., but is not limited thereto.

[0057] With such a setting, the bag feeding fixing plate 21 provides an installation space and support for the upper suction and transfer device 22, the lower suction and transfer device 23, and the bag suction device 24. When the bag feeding device 20 operates, the bag suction device 24 sucks and moves the packaging bag so that one side of the packaging bag contacts the upper suction and transfer device 22. And since the length of the upper suction and transfer device 22 is greater than that of the lower suction and transfer device 23, the packaging bag will not contact the lower suction and transfer device 23 during the movement by the bag suction device 24, thus affecting the movement route of the packaging bag. When one side of the packaging bag contacts the upper suction and transfer device 22, the bag suction device 24 stops adsorbing the packaging bag so that the packaging bag can be smoothly moved by the upper suction and transfer device 22. When the bag opening of the packaging bag is moved by the upper suction and transfer device 22 to the narrow end of the conical gap, the other side of the packaging bag contacts the lower suction and transfer device 23 and is adsorbed on the lower suction and transfer device 23. Since the packaging bag transportation direction of the lower suction and transfer device 23 is inclined to the packaging bag transportation direction of the upper suction and transfer device 22, when the packaging bag is moved from the narrow end of the conical gap to the wide end of the conical gap by the upper suction and transfer device 22 and the lower suction and transfer device 23, the bag opening of the packaging bag can be automatically opened, thus eliminating the need to set up an additional bag opening mechanism and saving costs.

[0058] In some embodiments, please also refer to Figure 3 and Figure 4 , the upper suction and transfer device 22 includes a mounting member 221, an upper suction and transfer rotating shaft 222, a plurality of upper vacuum bag transfer mechanisms 223, and an upper power unit 224.

[0059] The mounting member 221 is disposed on the bag feeding fixing plate 21. The mounting member 221 includes a plurality of partition plates arranged at intervals in a direction perpendicular to the packaging bag transportation direction of the upper suction and transfer device 22.

[0060] The upper suction and transfer rotating shaft 222 is rotatably disposed on the bag feeding fixing plate 21 and passes through the plurality of partition plates of the mounting member 221.

[0061] A plurality of upper vacuum bag transfer mechanisms 223 are disposed on the mounting member 221 and are connected to the upper suction and transfer rotating shaft 222. And each upper vacuum bag transfer mechanism 223 is respectively located between two adjacent partition plates of the mounting member 221 for adsorbing and moving the packaging bag.

[0062] The upper power unit 224 is disposed on the bag feeding fixing plate 21, and the power output end of the upper power unit 224 is connected to the upper suction and transfer rotating shaft 222 for driving the upper suction and transfer rotating shaft 222 to rotate so that the upper suction and transfer rotating shaft 222 drives the upper vacuum bag transfer mechanism 223 to move the packaging bag.

[0063] Among them, the upper vacuum bag transfer mechanism 223 is located above the lower suction and transfer device 23. The transport direction of the packaging bag of the lower suction and transfer device 23 is inclined to the transport direction of the packaging bag of the upper vacuum bag transfer mechanism 223 so as to form a conical gap between the upper vacuum bag transfer mechanism 223 and the lower suction and transfer device 23. The bag suction device 24 is located above the upper vacuum bag transfer mechanism 223. The length of the upper vacuum bag transfer mechanism 223 is greater than the length of the lower suction and transfer device 23 so that the packaging bag will not contact the lower suction and transfer device 23 during the process of the bag suction device 24 moving the packaging bag.

[0064] It can be understood that the mounting member 221 is a mechanism that can play a role in fixing and supporting. For example, the mounting member 221 may include a support shaft, a plurality of partition plates, etc., but is not limited thereto.

[0065] The upper suction and transfer rotating shaft 222 is a shaft body that can rotate and drive the upper vacuum bag transfer mechanism 223 to move the packaging bag. For example, the upper suction and transfer rotating shaft 222 may be a damping rotating shaft, a restrictive rotating shaft, etc., but is not limited thereto.

[0066] The upper vacuum bag transfer mechanism 223 is a mechanism that can adsorb and move the packaging bag. For example, the upper vacuum bag transfer mechanism 223 may include a suction device and a moving device for driving the suction device to move. The suction device may be a corrugated suction cup, a multi-point vacuum suction cup, etc., but is not limited thereto. The moving device may be a driving cylinder, a driving motor, etc., but is not limited thereto.

[0067] The upper power unit 224 is a mechanism that can drive the upper suction and transfer rotating shaft 222 to rotate so as to drive the upper vacuum bag transfer mechanism 223 to move the packaging bag. For example, the upper power unit 224 may be a DC motor, an AC motor, etc., but is not limited thereto. The connection mode between the upper power unit 224 and the upper suction and transfer rotating shaft 222 may be belt connection, gear connection, etc., but is not limited thereto.

[0068] With such a setting, the mounting member 221 provides support for the upper suction and transfer rotating shaft 222, the upper vacuum bag transfer mechanism 223 and the upper power unit 224. The upper power unit 224 drives the upper suction and transfer rotating shaft 222 to rotate so as to drive the upper vacuum bag transfer mechanism 223 to move the packaging bag. By respectively arranging the upper vacuum bag transfer mechanisms 223 between two adjacent partition plates of the mounting member 221, it is possible to avoid interference between the upper vacuum bag transfer mechanisms 223, thereby affecting the adsorption effect or the transport route of the packaging bag.

[0069] In some embodiments, please refer to Figure 3 and Figure 4 simultaneously, the upper vacuum bag transfer mechanism 223 includes an upper vacuum part 2231, an upper transmission wheel 2232, an upper conveyor belt 2233 and an upper air extraction member 2234.

[0070] The upper vacuum part 2231 is arranged on the mounting member 221 and directly below the gap between two adjacent partitions of the mounting member 221. An upper vacuum accommodating space is provided inside the upper vacuum part 2231. An upper ventilation hole communicating with the upper vacuum accommodating space is formed on one side of the upper vacuum part 2231 close to the lower suction and transfer device 23. The length of the upper vacuum part 2231 is greater than that of the lower suction and transfer device 23 so that the packaging bag will not contact the lower suction and transfer device 23 during the process of the bag suction device 24 moving the packaging bag.

[0071] The upper driving wheel 2232 is arranged on the upper suction and transfer rotating shaft 222 and between two adjacent partitions of the mounting member 221.

[0072] The upper conveyor belt 2233 is rotatably arranged on the upper driving wheel 2232 and the upper vacuum part 2231, and a part of the upper conveyor belt 2233 is located between two adjacent partitions of the mounting member 221. The upper conveyor belt 2233 is located above the lower suction and transfer device 23. The packaging bag transportation direction of the lower suction and transfer device 23 is inclined to the packaging bag transportation direction of the upper conveyor belt 2233 so as to form a tapered gap between the upper conveyor belt 2233 and the lower suction and transfer device 23, and a part of the upper conveyor belt 2233 is located below the bag suction device 24; A plurality of adsorption holes opposite to the positions of the upper ventilation holes of the upper vacuum part 2231 are formed on the upper conveyor belt 2233. The adsorption holes can communicate with the upper vacuum accommodating space through the upper ventilation holes. The upper conveyor belt 2233 is used to drive the packaging bag to move.

[0073] The upper air extraction member 2234 is arranged on the upper vacuum part 2231 and communicates with the upper vacuum accommodating space, and is used to extract the air in the upper vacuum accommodating space to provide an adsorption force to continuously adsorb the packaging bag on the upper conveyor belt 2233.

[0074] It can be understood that the upper vacuum part 2231 is a mechanism that can provide support for the upper conveyor belt 2233 and limit the moving direction of the packaging bag. For example, the upper vacuum part 2231 may include a vacuum rod, a plurality of guide wheels, etc., but is not limited thereto. Among them, the vacuum rod is a rod-shaped structure, and an upper vacuum accommodating space is provided inside the vacuum rod. An upper ventilation hole communicating with the upper vacuum accommodating space is formed on one side of the vacuum rod close to the lower suction and transfer device 23; At least two of the plurality of guide wheels are rotatably arranged at both ends of the vacuum rod respectively, and are used to assist the rotation of the upper conveyor belt 2233 to make the rotation of the upper conveyor belt 2233 smoother, and limit the rotation direction of the upper conveyor belt 2233 so as to limit the moving direction of the packaging bag.

[0075] The upper driving wheel 2232 is a wheel-shaped structure that can rotate and drive the upper conveyor belt 2233 to rotate, and is used to drive the upper conveyor belt 2233 to rotate so as to drive the packaging bag to move. For example, the upper driving wheel 2232 may be a pulley, a guide wheel, etc., but is not limited thereto.

[0076] The upper conveyor belt 2233 is a belt-like structure, and a plurality of suction holes are provided on the upper conveyor belt 2233 corresponding to the positions of the upper ventilation holes of the upper vacuum part 2231, so that the upper vacuum accommodation space of the upper vacuum part 2231 can communicate with the suction holes provided on the upper conveyor belt 2233. For example, the upper conveyor belt 2233 can be a rubber conveyor belt, a corrugated conveyor belt, etc., but is not limited thereto. The packaging bag transportation direction of the lower suction and transfer device 23 is inclined to the packaging bag transportation direction of the upper conveyor belt 2233 so as to form a tapered gap between the upper conveyor belt 2233 and the lower suction and transfer device 23.

[0077] The upper air extraction member 2234 is a device capable of extracting the air in the upper vacuum accommodation space of the upper vacuum part 2231. For example, the upper air extraction member 2234 can be an electric vacuum compression bag air extraction pump, a small rotary vane vacuum pump, etc., but is not limited thereto.

[0078] With such a setting, by rotatably arranging the upper conveyor belt 2233 on the upper driving wheel 2232 and the upper vacuum part 2231, and surrounding the upper driving wheel 2232 and the upper vacuum part 2231 with the upper conveyor belt 2233, the upper driving wheel 2232 can drive the upper conveyor belt 2233 to rotate along the length direction of the upper vacuum accommodation space of the upper vacuum part 2231 (the moving direction of the packaging bag) when rotating. When it is necessary to move the packaging bag, first, one side of the packaging bag contacts the upper conveyor belt 2233, and the upper air extraction member 2234 provided on the upper vacuum part 2231 and communicating with the upper vacuum accommodation space starts to extract air to form a vacuum environment in the upper vacuum accommodation space. Then, the vacuum adsorption force acts on the packaging bag in contact with the upper conveyor belt 2233 through the suction holes provided on the upper conveyor belt 2233, so that the packaging bag is firmly adsorbed on the upper conveyor belt 2233 and is moved to the wide end of the tapered gap through the rotation of the upper conveyor belt 2233.

[0079] In some embodiments, please refer to Figure 3 and Figure 4 , the lower suction and transfer device 23 includes a plurality of lower vacuum bag transfer mechanisms 231 and a lower driving part 232.

[0080] A plurality of lower vacuum bag transfer mechanisms 231 are arranged on the bag feeding fixing plate 21 and are located below the upper vacuum bag transfer mechanism 223. The packaging bag transportation direction of the lower vacuum bag transfer mechanism 231 is inclined to the packaging bag transportation direction of the upper conveyor belt 2233 so as to form a tapered gap between the lower vacuum bag transfer mechanism 231 and the upper conveyor belt 2233. The lower vacuum bag transfer mechanism 231 is used for adsorbing and moving the packaging bag to the bagging device 30. The length of the lower vacuum bag transfer mechanism 231 is less than the length of the upper vacuum part 2231 so that the packaging bag will not contact the lower vacuum bag transfer mechanism 231 during the process of the bag suction device 24 moving the packaging bag.

[0081] The lower driving part 232 is arranged on the bag feeding fixing plate 21 and on one side of the lower vacuum bag transferring mechanism 231, and the power output end of the lower driving part 232 is connected to the lower vacuum bag transferring mechanism 231, and is used to provide power for the lower vacuum bag transferring mechanism 231 to move the packaging bag.

[0082] It can be understood that the lower vacuum bag transferring mechanism 231 is a device capable of adsorbing and moving the packaging bag. For example, the lower vacuum bag transferring mechanism 231 may include a sucking device and a moving device for driving the sucking device to move. The sucking device may be a corrugated suction cup, a multi-point vacuum suction cup, etc., but is not limited thereto. The moving device may be a driving cylinder, a driving motor, etc., but is not limited thereto.

[0083] The lower driving part 232 is a device capable of providing power for the lower vacuum bag transferring mechanism 231 so that the lower vacuum bag transferring mechanism 231 can move the packaging bag. For example, the lower driving part 232 may be a DC motor, an AC motor, etc., but is not limited thereto.

[0084] With such a setting, the other side of the packaging bag is adsorbed on the lower vacuum bag transferring mechanism 231 through the lower vacuum bag transferring mechanism 231, and then the lower driving part 232 provides power for the lower vacuum bag transferring mechanism 231 so that the lower vacuum bag transferring mechanism 231 can move the packaging bag from the narrow end of the conical gap to the wide end of the conical gap, and through the packaging bag transportation direction of the lower vacuum bag transferring mechanism 231 which is inclined to the packaging bag transportation direction of the upper conveyor belt 2233, the bag opening of the packaging bag can be automatically opened during the process of moving the packaging bag from the narrow end of the conical gap to the wide end of the conical gap.

[0085] In some embodiments, please refer to Figure 3 and Figure 4 , the lower vacuum bag transferring mechanism 231 includes a lower vacuum part 2311, a lower auxiliary rotating shaft 2312, a lower conveyor belt 2313 and a lower air extraction part 2314.

[0086] The lower vacuum part 2311 is arranged on the bag feeding fixing plate 21 and directly below the upper vacuum part 2231. The lower vacuum part 2311 is internally provided with a lower vacuum accommodating space, and a lower ventilation hole communicating with the upper vacuum accommodating space is opened on one side of the lower vacuum part 2311 close to the upper suction and transfer device 22.

[0087] The lower auxiliary rotating shaft 2312 is rotatably arranged on the bag feeding fixing plate 21 and at one end of the lower vacuum part 2311 far from the lower driving part 232.

[0088] The lower conveyor belt 2313 is rotatably disposed on the power output shaft of the lower drive unit 232 and the lower auxiliary rotating shaft 2312 and surrounds the lower vacuum unit 2311. The lower conveyor belt 2313 is located below the upper conveyor belt 2233. The packaging bag transportation direction of the lower conveyor belt 2313 is inclined to the packaging bag transportation direction of the upper conveyor belt 2233 so as to form a tapered gap between the lower conveyor belt 2313 and the upper conveyor belt 2233. A plurality of lower adsorption holes are formed in the lower conveyor belt 2313 at positions corresponding to the lower ventilation holes of the lower vacuum unit 2311. The lower adsorption holes can communicate with the lower vacuum accommodation space through the lower ventilation holes. The lower conveyor belt 2313 is used to drive the packaging bag to move.

[0089] The lower air extraction member 2314 is disposed on the lower vacuum unit 2311 and communicates with the lower vacuum accommodation space, and is used to extract the air in the lower vacuum accommodation space to provide an adsorption force to continuously adsorb the packaging bag on the lower conveyor belt 2313.

[0090] Wherein, the length of the lower vacuum unit 2311 is less than the length of the upper vacuum unit 2231 so that the packaging bag will not contact the lower conveyor belt 2313 surrounding the lower vacuum unit 2311 during the process of the bag suction device 24 moving the packaging bag.

[0091] It can be understood that the lower vacuum unit 2311 is a plate-like structure with a lower vacuum accommodation space inside, which can limit the moving direction of the packaging bag. For example, the lower vacuum unit 2311 can be a plastic hollow plate, an aluminum hollow plate, etc., but is not limited thereto.

[0092] The lower auxiliary rotating shaft 2312 is a rotating shaft that can rotate and drive the lower conveyor belt 2313 to rotate. For example, the lower auxiliary rotating shaft 2312 can include a fixed rod and a rotating part, etc., but is not limited thereto. One end of the fixed rod is connected to the bag feeding fixing plate 21, and the rotating part is rotatably disposed at the other end of the fixed rod away from the bag feeding fixing plate 21. The lower conveyor belt 2313 is rotatably disposed on the rotating part. The fixed rod is a rod-like structure. For example, the fixed rod can be a copper fixed rod, an aluminum fixed rod, etc., but is not limited thereto. The rotating part is a rotatable structure. For example, the rotating part can be a rotating pulley, a deep groove ball bearing, etc., but is not limited thereto.

[0093] The lower conveyor belt 2313 is a belt-like structure. A plurality of lower adsorption holes are formed in the lower conveyor belt 2313 at positions corresponding to the upper ventilation holes of the lower vacuum unit 2311, so that the lower vacuum accommodation space of the lower vacuum unit 2311 can communicate with the lower adsorption holes formed in the lower conveyor belt 2313. For example, the lower conveyor belt 2313 can be a rubber conveyor belt, a corrugated conveyor belt, etc., but is not limited thereto. The packaging bag transportation direction of the lower conveyor belt 2313 is inclined to the packaging bag transportation direction of the upper conveyor belt 2233 so as to form a tapered gap between the lower conveyor belt 2313 and the upper conveyor belt 2233.

[0094] The lower air extraction member 2314 is a device capable of extracting air from the lower vacuum accommodation space of the lower vacuum part 2311. For example, the lower air extraction member 2314 can be an electric vacuum compression bag air extraction pump, a small rotary vane vacuum pump, etc., but is not limited thereto.

[0095] With such a setting, when the other side of the packaging bag contacts the lower conveyor belt 2313, the lower air extraction member 2314 continuously extracts the air in the lower vacuum accommodation space of the lower vacuum, causing the lower vacuum accommodation space to form a vacuum, and applying the vacuum adsorption force on the packaging bag in contact with the lower conveyor belt 2313 through the lower adsorption holes opened on the lower conveyor belt 2313, so that the other side of the packaging bag is firmly adsorbed on the lower conveyor belt 2313, and the lower conveyor belt 2313 is driven by the lower driving part 232 to rotate, so that the packaging bag can move from the narrow end of the conical gap to the wide end of the conical gap. Through the packaging bag transportation direction of the lower conveyor belt 2313 that is inclined to the packaging bag transportation direction of the upper conveyor belt 2233, when the packaging bag moves from the narrow end of the conical gap to the wide end of the conical gap, the two sides of the packaging bag forming the bag opening move away from each other, thereby realizing the automatic opening of the bag opening.

[0096] In some embodiments, please refer to Figure 5 , the bagging device 30 includes a rotary bag transporting device 31 and a loading device 32.

[0097] The rotary bag transporting device 31 is used to be arranged on the mounting plate 10 and is located on the side of the upper suction and transporting device 22 away from the bag suction device 24. The rotary bag transporting device 31 can be partially located in the conical gap to receive the packaging bags conveyed by the bag conveying device 20 and can rotate to move the packaging bags located in the conical gap to one side of the packing device 40.

[0098] The loading device 32 is used to be arranged on the mounting plate 10. The loading device 32 is located on the side of the rotary bag transporting device 31 away from the bag conveying device 20 and below the rotary bag transporting device 31, and is used to convey materials into the packaging bags, move the packaging bags filled with materials onto the packing device 40, and evacuate the air in the packaging bags.

[0099] It can be understood that the rotary bag transporting device 31 is a device capable of being partially located in the conical gap, adsorbing the packaging bags, and moving the adsorbed packaging bags from the conical gap to the side of the packing device 40. For example, the rotary bag transporting device 31 can include a suction device and a moving device for driving the suction device to move. The suction device can be a corrugated suction cup, a multi-point vacuum suction cup, etc., but is not limited thereto. The moving device can be a driving cylinder, a driving motor, etc., but is not limited thereto.

[0100] The loading device 32 is a device that can move materials into a packaging bag, move the packaging bag filled with materials onto the packing device 40, and evacuate the inside of the packaging bag while moving the packaging bag filled with materials onto the packing device 40. For example, the loading device 32 can include a material moving device for receiving materials and moving the materials to the side of the rotary bag transporting device 31, and a vacuum pushing device for moving the materials into the packaging bag on the rotary bag transporting device 31 and evacuating the inside of the packaging bag. For example, the material moving device can be a plate chain type material elevator, a reciprocating material elevator, etc., but is not limited thereto. The vacuum pushing device can include a hollow rod and an air extraction device capable of extracting air from the channel inside the hollow rod. For example, the hollow rod can be a plastic rod, an aluminum rod, etc., but is not limited thereto. The air extraction device can be an electric vacuum compression bag air extraction pump, a small rotary vane vacuum pump, etc., but is not limited thereto.

[0101] With such a setting, after the rotary bag transporting device 31 receives the packaging bags transported by the bag transporting device 20 and moves the received packaging bags to the side of the packing device 40 by rotation, the loading device 32 moves the materials into the packaging bags, then moves the packaging bags filled with materials onto the packing device 40, evacuates the inside of the packaging bags while moving the packaging bags, and finally seals the bag mouths of the packaging bags through the packing device 40 while evacuating the air, realizing automatic air evacuation and sealing, and improving work efficiency.

[0102] Exemplarily, the way the rotary bag transporting device 31 receives the packaging bags transported by the bag transporting device 20 can be that the vacuum adsorption force provided by the rotary bag transporting device 31 is greater than the vacuum adsorption force provided by the bag transporting device 20, so that the packaging bags are separated from the bag transporting device 20 and adsorbed on the rotary bag transporting device 31. It can also be that when the bag mouths of the packaging bags reach the wide ends of the conical gaps, the bag transporting device 20 stops providing vacuum adsorption force to separate the packaging bags from the bag transporting device 20, and at the same time, the rotary bag transporting device 31 provides vacuum adsorption force to adsorb the packaging bags on the rotary bag transporting device 31, etc., but is not limited thereto.

[0103] In some embodiments, please also refer to Figures 5 to 7 , the rotary bag transporting device 31 includes a bag transporting device mounting frame 311, a rotary platform 312, a plurality of opening and closing mechanisms 313, and a bag loading driving part 314.

[0104] The bag transporting device mounting frame 311 is used to be arranged on the mounting plate 10 and is located on the side of the upper suction and transfer device 22 away from the bag suction device 24.

[0105] The rotary platform 312 is rotatably arranged on the bag transporting device mounting frame 311 and is located between the bag transporting device mounting frame 311 and the upper suction and transfer device 22. A plurality of bag loading holes penetrating through the rotary platform 312 are formed on the rotary platform 312, and at least two bag loading holes are respectively located on both sides of the rotary platform 312.

[0106] A plurality of opening and closing mechanisms 313 are arranged on the rotating platform 312, and each opening and closing mechanism 313 is located beside the bagging hole. Each bagging hole corresponds to two opening and closing mechanisms 313 respectively. The opening and closing mechanism 313 can be partially located in the conical gap formed between the upper suction and transfer device 22 and the lower suction and transfer device 23. The opening and closing mechanism 313 is used to receive and fix the packaging bag, and the two opening and closing mechanisms 313 corresponding to the bagging hole can approach or separate from each other to change the opening and closing state of the packaging bag.

[0107] The bagging driving part 314 is arranged on the bag transporting device mounting frame 311, and the power output shaft of the bagging driving part 314 is connected to the rotating platform 312. The bagging driving part 314 is used to drive the rotating platform 312 to rotate.

[0108] It can be understood that the bag transporting device mounting frame 311 is a support member that can provide support for the rotating platform 312 and the bagging driving part 314. For example, the material of the bag transporting device mounting frame 311 can be copper, aluminum, etc., but is not limited thereto.

[0109] The rotating platform 312 is a plate-like structure that can rotate. For example, the rotating platform 312 can be a rectangular plate-like structure, a circular plate-like structure, etc., but is not limited thereto. At least two bagging holes penetrating the rotating platform 312 are formed on the rotating platform 312.

[0110] Exemplarily, when the number of bagging holes is even, every two bagging holes with the farthest linear distance are symmetric about the center point of the rotating platform 312. When the number of bagging holes is odd and the rotating platform 312 is a circular plate-like structure, rays are drawn from the center of the rotating platform 312 to the centers of each bagging hole, and the drawn rays can equally divide the rotating platform 312.

[0111] The opening and closing mechanism 313 is a device that can be rotatably arranged on the rotating platform 312 and is located beside the bagging hole, and is partially located in the conical gap, and can adsorb or not adsorb the packaging bag. For example, the opening and closing mechanism 313 can include a suction device for adsorbing or not adsorbing the packaging bag and a rotation driving device for driving the suction device to rotate. The suction device can be a corrugated suction cup, a multi-point vacuum suction cup, etc., but is not limited thereto. The rotation driving device can be a driving cylinder, a driving motor, etc., but is not limited thereto. Every two opening and closing mechanisms 313 are arranged oppositely and are respectively located on both sides of the bagging hole, so that the ends of the two opening and closing mechanisms 313 far from the rotating platform 312 can approach or move away from each other to close or open a part of the packaging bag adsorbed on the opening and closing mechanism 313.

[0112] Exemplarily, when there are two bagging holes formed in the rotary platform 312, the number of the opening and closing mechanisms 313 is four. Two of the four opening and closing mechanisms 313 correspond to one of the two bagging holes, and the other two of the four opening and closing mechanisms 313 correspond to the other one of the two bagging holes. The ends of the two opening and closing mechanisms 313 corresponding to the bagging holes, which are away from the bagging holes, can approach or move away from each other.

[0113] Exemplarily, when there are three bagging holes formed in the rotary platform 312, the number of the opening and closing mechanisms 313 is six. Two of the six opening and closing mechanisms 313 correspond to one of the three bagging holes, two of the other four opening and closing mechanisms 313 correspond to one of the other two bagging holes, and the last remaining two opening and closing mechanisms 313 correspond to the last remaining one bagging hole.

[0114] The bagging driving part 314 is a device capable of driving the rotary platform 312 to rotate. For example, the bagging driving part 314 can be a DC motor, an AC motor, etc., but is not limited thereto.

[0115] With such an arrangement, the two opening and closing mechanisms 313, part of which is located in the conical gap and part of which is located in the packaging bag, respectively adsorb the two sides of the packaging bag so that the packaging bag is adsorbed on the two opening and closing mechanisms 313. Then, the bagging driving part 314 drives the rotary platform 312 to rotate, thereby driving the opening and closing mechanisms 313 to rotate, so that the packaging bag adsorbed on the opening and closing mechanisms 313 leaves the conical gap and moves to the side of the packing device 40.

[0116] Optionally, the ends of the two opening and closing mechanisms 313 corresponding to the bagging holes and partially located within the conical gap and away from the rotary platform 312 are in a state of approaching each other, such that the two opening and closing mechanisms 313 corresponding to the bagging holes can be partially located within the packaging bag. The ends of the two opening and closing mechanisms 313 corresponding to the bagging holes and located beside the bagging device 40 and away from the rotary platform 312 are in a state of moving away from each other, such that the material can smoothly enter the packaging bag. When the bagging driving part 314 drives the rotary platform 312 to rotate, the ends of the two opening and closing mechanisms 313 corresponding to the bagging holes and partially located within the conical gap that approach each other during the process of rotating away from the conical gap will gradually move away from each other, and will be parallel to each other when the bagging driving part 314 stops driving the rotary platform 312 to rotate and is located beside the bagging device 40. When the bagging driving part 314 drives the rotary platform 312 to rotate, if the two opening and closing mechanisms 313 corresponding to the bagging holes and not located within the conical gap are within the conical gap when the rotary platform 312 stops rotating, then the ends of the two opening and closing mechanisms 313 corresponding to the bagging holes and away from the rotary platform 312 will approach each other during the rotation process, and will enable the two opening and closing mechanisms 313 corresponding to the bagging holes to smoothly be partially located within the conical space. When the bagging driving part 314 stops driving the rotary platform 312 to rotate, there must be a set of two opening and closing mechanisms 313 corresponding to the bagging holes located within the conical gap, and there must be a set of two opening and closing mechanisms 313 corresponding to the bagging holes located beside the bagging device 40.

[0117] In some embodiments, please refer to Figures 5 to 7 together, the opening and closing mechanism 313 includes an opening and closing fixing plate 3131, an opening and closing air cylinder 3132, and an opening and closing air extraction device 3133.

[0118] The opening and closing fixing plate 3131 is rotatably arranged on the rotary platform 312 and corresponds to the position of the bagging hole. The opening and closing fixing plate 3131 can be partially located within the conical gap. The two opening and closing fixing plates 3131 corresponding to the bagging hole can approach or separate from each other to change the opening and closing state of the packaging bag. An opening and closing accommodation space is provided inside the opening and closing fixing plate 3131, and an opening and closing ventilation hole communicating with the opening and closing accommodation space is provided on the opening and closing fixing plate 3131.

[0119] The opening and closing air cylinder 3132 is arranged on the rotary platform 312, and the power output end of the opening and closing air cylinder 3132 is hinged to the opening and closing fixing plate 3131. The opening and closing air cylinder 3132 is used to change the rotation angle of the opening and closing fixing plate 3131 such that the two opening and closing fixing plates 3131 corresponding to the bagging hole can approach or separate from each other.

[0120] The opening and closing air extraction device 3133 is arranged on one side of the opening and closing fixed plate 3131 close to the rotating platform 312. The opening and closing air extraction device 3133 is communicated with the opening and closing accommodation space, and is used to extract the air in the opening and closing accommodation space to provide an adsorption force to make the packaging bag adsorbed on the opening and closing fixed plate 3131.

[0121] It can be understood that the opening and closing fixed plate 3131 is a plate-like structure with an opening and closing accommodation space inside, and there are a plurality of opening and closing ventilation holes communicating with the opening and closing accommodation space on the opening and closing fixed plate 3131. One end of the opening and closing fixed plate 3131 is rotatably arranged on the rotating platform 312. For example, the material of the opening and closing fixed plate 3131 can be copper, aluminum, etc., but is not limited thereto.

[0122] The opening and closing air cylinder 3132 is a mechanism that can drive the rotation of the opening and closing fixed plate 3131. For example, the opening and closing air cylinder 3132 can be an electric air cylinder, a piston air cylinder, etc., but is not limited thereto. By hingedly connecting the opening and closing fixed plate 3131 with the power output end of the opening and closing air cylinder 3132, the opening and closing fixed plate 3131 can be rotated within a certain range while maintaining the stability of the connection.

[0123] The opening and closing air extraction device 3133 is a device that can continuously extract the air in the opening and closing accommodation space. For example, the opening and closing air extraction device 3133 can be an electric vacuum compression bag air extraction pump, a small rotary vane vacuum pump, etc., but is not limited thereto.

[0124] With such a setting, the opening and closing air extraction device 3133 continuously extracts the air in the opening and closing accommodation space to form a vacuum in the opening and closing accommodation space, and then the vacuum adsorption force acts on the packaging bag in contact with the opening and closing fixed plate 3131 through the opening and closing ventilation holes opened on the opening and closing fixed plate 3131, so that the packaging bag is firmly adsorbed on the opening and closing fixed plate 3131. The opening and closing air cylinder 3132 drives the opening and closing fixed plate 3131 to rotate, so that the ends of the two opening and closing fixed plates 3131 corresponding to the bag loading holes and away from the rotating platform 312 approach each other, so that the two opening and closing fixed plates 3131 corresponding to the bag loading holes can be partially located in the conical gap, or the ends of the two opening and closing fixed plates 3131 corresponding to the bag loading holes and away from the rotating platform 312 move away from each other to open the accommodation bag body of the packaging bag, so that the material can smoothly enter the inside of the packaging bag.

[0125] In some embodiments, please refer to Figure 5 and Figure 8 , the loading device 32 includes a lifting device 321, a first pushing device 322 and a second pushing device 323.

[0126] The lifting device 321 is used to be arranged on the mounting plate 10. The lifting device 321 is located below the bag conveying device mounting frame 311 and on the side of the rotating platform 312 away from the bag feeding device 20, and is used to change the height of the material so that the material can be at the same height as the bagging hole.

[0127] The first pusher device 322 is used to be arranged on the mounting plate 10 and on the side of the lifting device 321 away from the rotating platform 312, and the first pusher device 322 is used to move the material onto the lifting device 321.

[0128] The second pusher device 323 is used to be arranged on the mounting plate 10 and above the first pusher device 322. The second pusher device 323 corresponds to the position of the bagging hole with the lowest height among the multiple bagging holes opened on the rotating platform 312, and is used to push the material from the lifting device 321 into the packaging bag through the bagging hole, move the packaging bag filled with the material onto the packing device 40, and at the same time extract the air in the packaging bag.

[0129] It can be understood that the lifting device 321 is a device that can receive the material and change the height of the material so that the material is beside the bagging hole. For example, the lifting device 321 can be a hydraulic lifting device, a pneumatic lifting device, etc., but is not limited thereto.

[0130] The first pusher device 322 is a device that can push the material and move the material onto the lifting device 321. For example, the first pusher device 322 can be a hydraulic pushing device, a pneumatic pushing device, etc., but is not limited thereto.

[0131] The second pusher device 323 is a device that can push the material on the lifting device 321 into the packaging bag, push the packaging bag filled with the material onto the packing device 40, and evacuate the packaging bag during the process of pushing the material. For example, the second pusher device 323 can include a vacuum pushing device for pushing the material into the packaging bag, pushing the packaging bag filled with the material onto the packing device 40 and evacuating the packaging bag, and a moving mechanism for driving the vacuum pushing device to move. For example, the vacuum pushing device can include a hollow rod and an air extraction device capable of extracting the air in the channel of the hollow rod. For example, the hollow rod can be a plastic rod, an aluminum rod, etc., but is not limited thereto. The air extraction device can be an electric vacuum compression bag air extraction pump, a small rotary vane vacuum pump, etc., but is not limited thereto. The moving mechanism can be a driving cylinder, a driving motor, etc., but is not limited thereto.

[0132] With such a setting, the material is moved to the lifting device 321 at the same height as the first pusher device 322 by the first pusher device 322, and then the height of the material is increased by the pusher device so that the material is at the same height as the second pusher device 323. Finally, the material on the pusher device is moved into the packaging tape adsorbed by the opening and closing mechanism 313 by the second pusher device 323, and the material is continuously pushed to make the material press against the packaging bag, causing the packaging bag to disengage from the opening and closing mechanism 313 and move to the packing device 40. At the same time, the second pusher device 323 continuously evacuates the packaging bag, so that the inside of the packaging bag is in a vacuum state when it moves to the packing device 40, improving work efficiency.

[0133] In some embodiments, please refer to Figures 8 to 9 together. The second pusher device 323 includes a moving mechanism 3231 and a vacuum pusher mechanism 3232.

[0134] The moving mechanism 3231 is configured to be disposed on the mounting plate 10 and above the first pusher device 322, and on the side of the rotating platform 312 away from the bag feeding device 20.

[0135] The vacuum pusher mechanism 3232 is disposed on the moving mechanism 3231 and corresponds to the position of the lowest-height bagging hole among the plurality of bagging holes opened in the rotating platform 312; the moving mechanism 3231 is used to drive the vacuum pusher mechanism 3232 to move, so that the vacuum pusher mechanism 3232 pushes the material from the lifting device 321 into the packaging bag through the bagging hole and moves the packaging bag filled with the material to the packing device 40, while evacuating the air inside the packaging bag.

[0136] It can be understood that the moving mechanism 3231 is a mechanism capable of driving the vacuum pusher mechanism 3232 to reciprocate. For example, the moving mechanism 3231 can be a gear-rack mechanism, a linkage mechanism, etc., but is not limited thereto.

[0137] The vacuum pusher mechanism 3232 is a mechanism capable of pushing the material from the lifting device 321 into the packaging bag through the bagging hole and moving the packaging bag filled with the material to the packing device 40, while evacuating the air inside the packaging bag. For example, the vacuum pusher mechanism 3232 can include a hollow rod and an air extraction device capable of extracting the air in the channel of the hollow rod. For example, the hollow rod can be a plastic rod, an aluminum rod, etc., but is not limited thereto, and the air extraction device can be an electric vacuum compression bag air extraction pump, a small rotary vane vacuum pump, etc., but is not limited thereto.

[0138] With such a setting, the moving mechanism 3231 drives the vacuum pusher mechanism 3232 to move, thereby moving the material into the packaging bag and moving the packaging bag filled with the material to the packing device 40. The vacuum pusher mechanism 3232 evacuates the air inside the packaging bag while moving the packaging bag, so that a vacuum is formed inside the packaging bag, improving work efficiency.

[0139] In some embodiments, referring to Figures 9 to 10 , the vacuum goods pushing mechanism 3232 includes a goods pushing fixed block 32321, a push rod 32322, a push shell 32323, an air extraction pipe 32324, an air extraction spring 32325, and a push shell air extraction device 32326.

[0140] The goods pushing fixed block 32321 is arranged on the moving mechanism 3231.

[0141] One end of the push rod 32322 is connected to the goods pushing fixed block 32321.

[0142] The push shell 32323 is arranged at the other end of the push rod 32322. There is a push shell 32323 accommodation space inside the push shell 32323, and a push shell 32323 groove is provided on the surface of the push shell 32323.

[0143] The air extraction pipe 32324 is rotatably arranged on the push shell 32323 and partially located in the push shell 32323 groove. The air extraction pipe 32324 is a hollow pipe, and the pipeline formed inside the air extraction pipe 32324 is communicated with the push shell 32323 accommodation space.

[0144] One end of the air extraction spring 32325 is connected to the air extraction pipe 32324, and the other end of the air extraction spring 32325 is connected to the push shell 32323 and located in the push shell 32323 groove. The air extraction spring 32325 is used to change the position of the air extraction pipe 32324 so that the air extraction pipe 32324 can be in a state of being partially located in the push shell 32323 groove without being affected by external forces.

[0145] The push shell air extraction device 32326 is arranged on the push shell 32323 and communicated with the push shell 32323 accommodation space, and is used to extract the air inside the packaging bag through the air extraction pipe 32324.

[0146] It can be understood that the goods pushing fixed block 32321 is a block-shaped connecting piece for connecting the push rod 32322 and the moving mechanism 3231. For example, the material of the goods pushing fixed block 32321 can be plastic, aluminum, etc., but is not limited thereto.

[0147] The push rod 32322 is a rod-shaped structure and is used to drive the push shell 32323 to move. For example, the push rod 32322 can be a plastic rod, an aluminum hollow rod, etc., but is not limited thereto.

[0148] The push shell 32323 is a shell-shaped structure. For example, the push shell 32323 can be an aluminum shell, a plastic shell, etc., but is not limited thereto.

[0149] The air extraction pipe 32324 is a tubular structure. The air extraction pipe 32324 is connected to the accommodating space of the shell pushing member 32323 and is used to extract the air inside the packaging bag. For example, the air extraction pipe 32324 can be an aluminum pipe, a plastic pipe, etc., but is not limited thereto.

[0150] The air extraction spring 32325 is a spring used to provide elastic force for the air extraction pipe 32324 so that the air extraction pipe 32324 can be partially located outside the groove of the shell pushing member 32323 and be parallel to the moving direction of the push rod 32322 when not affected by other external forces. For example, the air extraction spring 32325 can be a compression spring, a torsion spring, etc., but is not limited thereto.

[0151] The shell pushing and air extraction device 32326 is a device capable of continuously extracting the air inside the accommodating space of the shell pushing member 32323. For example, the shell pushing and air extraction device 32326 can be an electric vacuum compression bag air extraction pump, a small rotary vane vacuum pump, etc., but is not limited thereto.

[0152] With such a setting, when the material is beside the bagging hole, the moving mechanism 3231 drives the goods pushing fixing block 32321 to move. The goods pushing fixing block 32321 drives the push rod 32322 to move, thereby driving the shell pushing member 32323 close to the packaging bag, so that the material passes through the bagging hole and is located inside the packaging bag adsorbed on the opening and closing mechanism 313 and between the two opening and closing mechanisms 313 corresponding to the bagging hole. Then, the moving mechanism 3231 continues to drive the shell pushing member 32323 to move towards the packaging device 40, so that the shell pushing member 32323 drives the material located inside the packaging bag to move towards the packaging device 40 together with the packaging bag. At the same time, the shell pushing and air extraction device 32326 continuously extracts the air inside the packaging bag through the air extraction pipe 32324 connected to the accommodating space of the shell pushing member 32323 and located inside the packaging bag, so as to form a vacuum inside the packaging bag. When the packaging bag is on the packaging device 40, the moving mechanism 3231 adjusts the position of the shell pushing member 32323 so that the shell pushing member 32323 is located outside the packaging bag and the air extraction pipe 32324 is partially located inside the packaging bag. After the packaging bag is sealed by the packaging device 40, the moving mechanism 3231 drives the shell pushing member 32323 away from the packaging bag and passes through the bagging hole, enabling the rotary platform 312 to rotate normally.

[0153] In some embodiments, please refer to Figure 11 , the packaging device 40 includes a sealing device 41, a packaging conveying device, and a packaging pushing device 43.

[0154] The sealing device 41 is arranged on the mounting plate 10 and is used to seal the opening of the packaging bag.

[0155] The packaging conveying device 42 is used to receive and move the packaging bag that has been loaded with materials transported by the loading device 32.

[0156] The packing pushing device 43 is arranged on the packing conveyor device 42 and is used to move the packaging bag containing materials on the packing conveyor device 42.

[0157] It can be understood that the sealing device 41 is a device capable of sealing the packaging bag containing materials. For example, the sealing device 41 can be a fully automatic rolling sealer, a heat sealer, etc., but is not limited thereto.

[0158] The packing conveyor device 42 is a device capable of moving the packaging bag containing materials. For example, the packing conveyor device 42 can be a roller conveyor, a chain conveyor, etc., but is not limited thereto.

[0159] The packing pushing device 43 is a device capable of translating the packaging bag containing materials as a whole. For example, the packing pushing device 43 can include a packing power unit, a packing push plate, etc., but is not limited thereto. Among them, the packing power unit is a mechanism capable of driving the packing push plate to approach or move away from the packaging bag containing materials. For example, the packing power unit can be a driving motor, a driving cylinder, etc., but is not limited thereto. The packing push plate is a plate-like structure capable of driving the packaging bag containing materials to approach the sealing device 41. For example, the packing push plate can be a plastic plate, an aluminum plate, etc., but is not limited thereto.

[0160] With such a setting, when the packaging bag containing materials is on the packing conveyor device 42, the packing pushing device 43 pushes the packaging bag containing materials to approach the sealing device 41 and makes the bag mouth of the packaging bag located inside the sealing device 41. At the same time, during the process of the packing pushing device 43 pushing the packaging bag containing materials, the air extraction pipe 32324 receives the thrust of the packing pushing device 43, causing the air extraction pipe 32324 to approach the groove of the push shell 32323 and compress the air extraction spring 32325. When the bag mouth of the packaging bag is completely located inside the sealing device 41, the air extraction pipe 32324 is completely located inside the groove of the push shell 32323. When the sealing device 41 completes the sealing operation on the bag mouth of the packaging bag, the packing conveyor device 42 drives the sealed packaging bag away from the sealing device 41 and outputs the packaging bag containing materials. The packing pushing device 43 resets so that the packing pushing device 43 can continue to push the packaging bag containing materials to make the packaging bag containing materials approach the sealing device 41. At the same time, the air extraction spring 32325 compressed by the packing pushing device 43 releases the compressed elastic force during the reset process of the packing pushing device 43, causing the air extraction pipe 32324 to partially leave the groove of the push shell 32323.

[0166] The transport device 1200 is a device capable of moving packaging bags or materials. For example, the transport device 1200 can be a roller conveyor, a chain conveyor, etc., but is not limited thereto.

[0167] From the above, it can be seen that the flat-push type bag feeding packaging machine 1000 provided by the embodiment of the present application can move the packaging bag to directly below the bag suction device 24, move the material to beside the lifting device 321, and output the packaging bag with the sealing completed.

Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present application shall be included within the protection scope of the present application.
