[0018] The bagging and packaging mechanism of the push-type bag packaging machine is the core part of the packaging process. It can transport bags and accurately load materials into bags, and perform subsequent processing such as sealing. The bagging and packaging mechanism usually includes multiple key components such as the bag transport mechanism, bag opening mechanism, and bagging mechanism, which work together to complete the bagging and packaging tasks.

[0019] The bagging and packaging mechanism of the push-type bag-feeding packaging machine in the related art needs to open the bag mouth by setting up an independent bag opening mechanism. The existence of the bag opening mechanism increases the cost of the push-type bag-feeding packaging machine, and after the bag is loaded with materials, the bag is usually vacuumed and the bag mouth is sealed manually, resulting in low production efficiency.

[0020] Based on this, in order to improve the problem in the related art that an independent bag opening mechanism is required, which leads to increased costs, and the low efficiency of manually vacuuming the bag and sealing the bag opening, the embodiments of the present application provide the following solution.

[0021] Please also read Figure 1 and Figure 2 The embodiment of the present application provides a bagging and packaging mechanism 100, which is applied to a push-type bag-feeding and packaging machine 1000. The push-type bag-feeding and packaging machine 1000 includes a housing 1100 and a plurality of transport devices 1200. The housing 1100 has a housing accommodating space. The bagging and packaging mechanism 100 is used to be arranged in the housing accommodating space. The transport device 1200 is partially located in the housing accommodating space and is used to transport packaging bags or materials to the bagging and packaging mechanism 100, or receive packaging bags containing materials output by the bagging and packaging mechanism 100 so that the packaging bags containing materials are away from the bagging and packaging mechanism 100. The bagging and packaging mechanism 100 includes a mounting plate 10, a bag feeding device 20, a bagging device 30 and a packaging device 40, wherein: The mounting plate 10 is used to be disposed on the casing 1100 and is located in the casing accommodation space.

[0022] The bag conveying device 20 is arranged on the mounting plate 10, and the bag conveying device 20 includes an upper suction and transmission device 22 and a lower suction and transmission device 23 which are arranged relatively to each other. The upper suction and transmission device 22 is used to absorb one side of the packaging bag and convey the packaging bag, and the lower suction and transmission device 23 is used to absorb the other side of the packaging bag and convey the packaging bag; the packaging bag transportation direction of the lower suction and transmission device 23 is inclined to the packaging bag transportation direction of the upper suction and transmission device 22 so that a conical gap is formed between the upper suction and transmission device 22 and the lower suction and transmission device 23, so that the packaging bag can be automatically opened while being moved from the narrow end of the conical gap to the wide end of the conical gap by the upper suction and transmission device 22 and the lower suction and transmission device 23; wherein, the opening size of the narrow end of the conical gap is smaller than the opening size of the wide end of the conical gap.

[0023] The bagging device 30 is arranged on the mounting plate 10 and is located at the output side of the bag feeding device 20. It is used to receive the packaging bags output by the bag feeding device 20, and convey the materials to be packaged in the packaging bags into the packaging bags and then extract the air in the packaging bags to form a vacuum environment.

[0024] The packaging device 40 is disposed on the mounting plate 10 and is located at the output side of the bagging device 30 , and is used for receiving the packaging bags containing materials output by the bagging device 30 and sealing the packaging bags containing materials after vacuuming.

[0025] It can be understood that the mounting plate 10 is a plate-like structure that can play a supporting and fixing role. For example, the mounting plate 10 can be a copper plate, or an aluminum plate, etc., but is not limited thereto.

[0026] The bag conveying device 20 is a device that can absorb the packaging bag on the transport device 1200 and move the packaging bag to the bagging device 30. The upper suction and transmission device 22 is a device that can absorb the packaging bag and move the packaging bag close to the bagging device 30. For example, the upper suction and transmission device 22 may include a suction device and a moving device that drives 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 to this. The moving device may be a driving cylinder, a driving motor, etc., but is not limited to this. The lower suction and transmission device 23 is a device that can absorb the packaging bag and move the packaging bag close to the bagging device 30. For example, the lower suction and transmission device 23 may include a suction device and a moving device that drives 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 to this. The moving device may be a driving cylinder, a driving motor, etc., but is not limited to this. The narrow end of the conical gap refers to the shortest distance between the upper suction transmission device 22 and the lower suction transmission device 23 in the direction of gravity, and the wide end of the conical gap refers to the longest distance between the upper suction transmission device 22 and the lower suction transmission device 23 in the direction of gravity. The lower suction transmission device 23 can be located directly below the upper suction transmission device 22.

[0027] The bagging device 30 is a device that can receive the packaging bag output by the bag feeding device 20 and move the material into the packaging bag, then move the material in the packaging bag to the packaging device 40, and evacuate the packaging bag while moving the material in the packaging bag to the packaging device 40. For example, the bagging device 30 may include a suction device, a moving device that drives the suction device to move, and a vacuum push rod that can move the material into the packaging bag and evacuate the packaging bag. The suction device may be a corrugated suction cup, a multi-point vacuum suction cup, etc., but not limited thereto. The moving device may be a driving cylinder, a driving motor, etc., but not limited thereto. The vacuum push rod may include a hollow rod and an exhaust device that can extract the air in the channel inside the hollow rod. For example, the hollow rod may be a plastic rod, an aluminum rod, etc., but not limited thereto. The exhaust device may be an electric vacuum compression bag exhaust pump, a small rotary vane vacuum pump, etc., but not limited thereto.

[0028] The packaging device 40 is a device capable of receiving the packaging bag containing materials output by the bagging device 30 and sealing the bag opening of the packaging bag. For example, the packaging device 40 may include a sealing machine capable of sealing the packaging bag and a conveying device capable of transporting the packaging bag to the sealing machine and outputting the packaging bag sealed by the sealing machine. For example, the sealing machine may be a fully automatic rolling sealing machine, a heating sealing machine, etc., but not limited thereto, and the conveying device may be a roller conveyor, a chain conveyor, etc., but not limited thereto.

[0029] As can be seen from the above, the bagging and packaging mechanism 100 provided in the embodiment of the present application, through the bag feeding device 20 arranged on the mounting plate 10, can make the bag mouth of the packaging bag automatically open through the action of the mutually inclined transportation directions of the upper suction and transmission device 22 and the lower suction and transmission device 23 of the bag feeding device 20 during the process of the packaging bag being transported from the bag feeding device 20 to the bagging device 30, so that the horizontal push type bag feeding and packaging machine 1000 does not need to additionally set up an independent bag opening mechanism to open the bag mouth, thereby reducing the cost of the horizontal push type bag feeding and packaging machine 1000; and by being arranged on the mounting plate 10 and being able to partially After receiving the packaging bag conveyed by the bag feeding device 20, the bag filling device 30 located between the upper suction and transfer device 22 and the lower suction and transfer device 23 of the bag feeding device 20 pushes the material into the packaging bag and moves the packaging bag containing the material to the packaging device 40, and continuously vacuums the packaging bag during the process of moving the packaging bag containing the material to the packaging device 40; finally, the packaging device 40 arranged on the mounting plate 10 completes the sealing operation of the packaging bag while the bag filling device 30 vacuums the packaging bag, thereby improving the technical problem of low efficiency of manually vacuuming the bag and sealing the bag opening.

[0030] In some embodiments, please refer to Figure 3 and Figure 4 The bag feeding device 20 also includes a bag feeding fixing plate 21 and a bag suction device 24.

[0031] The bag feeding fixing plate 21 is disposed on the mounting plate 10 and is used to fix the bag feeding device 20 .

[0032] The bag suction device 24 is disposed on the bag feeding fixing plate 21 and is located above the upper suction and transmission device 22 , and is used for sucking and moving the packaging bag so that one side of the packaging bag contacts the upper suction and transmission device 22 .

[0033] Among them, the upper suction and transfer device 22 is arranged on the bag feeding fixing plate 21; the lower suction and transfer device 23 is arranged on the bag feeding fixing plate 21, and is located below the upper suction and transfer device 22; the length of the upper suction and transfer device 22 is greater than the length of the lower suction and transfer device 23 so that the bag suction device 24 will not contact the lower suction and transfer device 23 during the process of moving the packaging bag, the bag suction device 24 is located on one side of the narrow end of the conical gap, and the bag suction device 24 is located on the side of the lower suction and transfer device 23 away from the bagging device 30.

[0034] It can be understood that the bag feeding fixing plate 21 is a plate-like structure that can play a supporting and fixing role. For example, the bag feeding fixing plate 21 can be a copper plate, or an aluminum plate, etc., but is not limited thereto.

[0035] The length of the upper suction transfer device 22 along the transport direction of the packaging bag can be greater than the length of the lower suction transfer device 23 along the transport direction of the packaging bag. The bag suction device 24 is a device that can suck and move the packaging bag so that one side of the packaging bag contacts the upper suction transfer device 22. For example, the bag suction device 24 may include a bag suction moving part, at least one suction nozzle, etc., but is not limited to this. Among them, the suction nozzle is connected to the power output end of the bag suction moving part, and the bag suction moving part is a device that can drive the suction nozzle to approach or move away from the upper suction transfer device 22. For example, the bag suction moving part can be a driving motor, a driving cylinder, etc., but is not limited to this. 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 to this.

[0036] In this way, the bag feeding fixing plate 21 provides installation space and support for the upper suction device 22, the lower suction device 23 and the bag suction device 24. When the bag feeding device 20 is working, the bag suction device 24 sucks and moves the packaging bag so that one side of the packaging bag contacts the upper suction device 22. Since the length of the upper suction device 22 is greater than that of the lower suction device 23, the packaging bag will not contact the lower suction device 23 during the process of being moved by the bag suction device 24, thereby affecting the moving route of the packaging bag. When one side of the packaging bag contacts the upper suction device 22, the bag suction device 24 stops sucking the packaging bag so that the packaging bag can be smoothly moved by the upper suction device 22. When the bag mouth of the packaging bag is moved to the narrow end of the conical gap by the upper suction and transfer device 22, 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 mouth of the packaging bag can be automatically opened, thereby eliminating the need to set up an additional bag opening mechanism, saving costs.

[0037] In some embodiments, please refer to Figure 3 and Figure 4The 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 .

[0038] The mounting member 221 is disposed on the bag feeding fixing plate 21 , and the mounting member 221 includes a plurality of partitions sequentially arranged at intervals in a direction perpendicular to the packaging bag conveying direction of the upper suction transfer device 22 .

[0039] The upper suction transmission shaft 222 is rotatably disposed on the bag feeding fixing plate 21 and passes through a plurality of partitions of the mounting member 221 .

[0040] A plurality of upper vacuum bag transfer mechanisms 223 are disposed on the mounting member 221 and connected to the upper suction transmission shaft 222 , and each upper vacuum bag transfer mechanism 223 is located between two adjacent partitions of the mounting member 221 for adsorbing and moving packaging bags.

[0041] The upper power unit 224 is disposed on the bag feeding fixing plate 21, and a power output end of the upper power unit 224 is connected to the upper suction transmission shaft 222 for driving the upper suction transmission shaft 222 to rotate, so that the upper suction transmission shaft 222 drives the upper vacuum bag moving mechanism 223 to move the packaging bag.

[0042] Among them, the upper vacuum bag moving mechanism 223 is located above the lower suction and transfer device 23, and the packaging bag transportation direction of the lower suction and transfer device 23 is inclined to the packaging bag transportation direction of the upper vacuum bag moving mechanism 223 so that a conical gap is formed between the upper vacuum bag moving mechanism 223 and the lower suction and transfer device 23. The bag suction device 24 is located above the upper vacuum bag moving mechanism 223, and the length of the upper vacuum bag moving 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 when the bag suction device 24 moves the packaging bag.

[0043] It can be understood that the mounting member 221 is a mechanism that can play a fixing and supporting role. For example, the mounting member 221 can include a support shaft, a plurality of partitions, etc., but is not limited thereto.

[0044] The upper suction transmission shaft 222 is a shaft that can rotate and drive the upper vacuum bag transfer mechanism 223 to move the packaging bag. For example, the upper suction transmission shaft 222 can be a damping shaft, a restrictive shaft, etc., but is not limited thereto.

[0045] The upper vacuum bag transfer mechanism 223 is a mechanism capable of sucking or moving packaging bags. 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 not limited thereto. The moving device may be a driving cylinder, a driving motor, etc., but not limited thereto.

[0046] The upper power unit 224 is a mechanism that can drive the upper suction transmission shaft 222 to rotate, thereby driving the upper vacuum bag transfer mechanism 223 to move the packaging bag. For example, the upper power unit 224 can be a DC motor, an AC motor, etc., but not limited thereto. The connection method between the upper power unit 224 and the upper suction transmission shaft 222 can be a belt connection, a gear connection, etc., but not limited thereto.

[0047] In this arrangement, the mounting member 221 provides support for the upper suction transmission shaft 222, the upper vacuum bag transfer mechanism 223 and the upper power unit 224. The upper suction transmission shaft 222 is driven to rotate by the upper power unit 224, thereby driving the upper vacuum bag transfer mechanism 223 to move the packaging bag. By respectively arranging the upper vacuum bag transfer mechanism 223 between two adjacent partitions of the mounting member 221, it is possible to avoid mutual interference between the upper vacuum bag transfer mechanisms 223, thereby affecting the suction effect or transportation route of the packaging bag.

[0048] In some embodiments, please refer to Figure 3 and Figure 4 The upper vacuum bag transfer mechanism 223 includes an upper vacuum portion 2231 , an upper transmission wheel 2232 , an upper conveyor belt 2233 and an upper suction member 2234 .

[0049] The upper vacuum portion 2231 is arranged on the mounting member 221 and is located directly below the gap between two adjacent partitions of the mounting member 221. An upper vacuum containing space is arranged inside the upper vacuum portion 2231. An upper vent hole connected to the upper vacuum containing space is arranged on one side of the upper vacuum portion 2231 close to the lower suction and transfer device 23. The length of the upper vacuum portion 2231 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 when the suction bag device 24 moves the packaging bag.

[0050] The upper transmission wheel 2232 is disposed on the upper suction transmission shaft 222 and is located between two adjacent partitions of the mounting member 221 .

[0051] The upper conveyor belt 2233 can be transmission-disposed on the upper transmission wheel 2232 and the upper vacuum part 2231, and a portion of the upper conveyor belt 2233 is located between two adjacent partitions of the mounting member 221, and the upper conveyor belt 2233 is located above the lower suction and transfer device 23, and 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 that a conical gap is formed between the upper conveyor belt 2233 and the lower suction and transfer device 23, and a portion of the upper conveyor belt 2233 is located below the bag suction device 24; a plurality of adsorption holes corresponding to the upper air holes of the upper vacuum part 2231 are provided on the upper conveyor belt 2233, and the adsorption holes can be connected with the upper vacuum containing space through the upper air holes, and the upper conveyor belt 2233 is used to drive the packaging bags to move.

[0052] The upper suction member 2234 is disposed on the upper vacuum portion 2231 and communicates with the upper vacuum containing space, and is used to extract air in the upper vacuum containing space to provide adsorption force so that the packaging bag is continuously adsorbed on the upper conveyor belt 2233 .

[0053] 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 containing space is provided inside the vacuum rod. An upper vent hole connected to the upper vacuum containing space is provided on one side of the vacuum rod close to the lower suction and transmission device 23; at least two of the plurality of guide wheels are rotatably arranged at both ends of the vacuum rod, respectively, to assist the rotation of the upper conveyor belt 2233 so that the rotation of the upper conveyor belt 2233 is smoother, and to limit the rotation direction of the upper conveyor belt 2233, thereby limiting the moving direction of the packaging bag.

[0054] The upper transmission 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 and thus drive the packaging bag to move. For example, the upper transmission wheel 2232 can be a pulley, a guide wheel, etc., but is not limited to this.

[0055] The upper conveyor belt 2233 is a belt-shaped structure, and a plurality of adsorption holes are provided on the upper conveyor belt 2233, which are opposite to the upper vent holes of the upper vacuum part 2231, so that the upper vacuum storage space of the upper vacuum part 2231 can be connected with the adsorption 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 conveying device 23 is inclined to the packaging bag transportation direction of the upper conveyor belt 2233 so that a conical gap is formed between the upper conveyor belt 2233 and the lower suction conveying device 23.

[0056] The upper suction member 2234 is a device capable of extracting air from the upper vacuum accommodation space of the upper vacuum portion 2231. For example, the upper suction member 2234 may be an electric vacuum compression bag suction pump, a small rotary vane vacuum pump, etc., but is not limited thereto.

[0057] In this way, the upper conveyor belt 2233 is arranged on the upper transmission wheel 2232 and the upper vacuum part 2231 in a transmission manner, and the upper conveyor belt 2233 surrounds the upper transmission wheel 2232 and the upper vacuum part 2231, so that the upper transmission wheel 2232 can drive the upper conveyor belt 2233 to rotate along the length direction of the vacuum containing space on the upper vacuum part 2231 (the moving direction of the packaging bag) when rotating. When the packaging bag needs to be moved, first one side of the packaging bag contacts the upper conveyor belt 2233, and the upper exhaust member 2234 arranged on the upper vacuum part 2231 and connected to the upper vacuum containing space starts to exhaust air to form a vacuum environment in the upper vacuum containing space, and then the vacuum suction force is applied to the packaging bag in contact with the upper conveyor belt 2233 through the suction holes opened 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 conical gap through the rotation of the upper conveyor belt 2233.

[0058] In some embodiments, please refer to Figure 3 and Figure 4 The lower suction transfer device 23 includes a plurality of lower vacuum bag transfer mechanisms 231 and a lower driving unit 232 .

[0059] 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 transporting direction of the lower vacuum bag transfer mechanism 231 is inclined to the packaging bag transporting direction of the upper conveyor belt 2233 so that a conical gap is formed between the lower vacuum bag transfer mechanism 231 and the upper conveyor belt 2233. The lower vacuum bag transfer mechanism 231 is used to absorb and move 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 when the bag suction device 24 moves the packaging bag.

[0060] The lower driving part 232 is arranged on the bag feeding fixing plate 21 and is located on one side of the lower vacuum bag moving mechanism 231, and the power output end of the lower driving part 232 is connected to the lower vacuum bag moving mechanism 231 to provide power for the lower vacuum bag moving mechanism 231 to move the packaging bags.

[0061] It can be understood that the lower vacuum bag transfer mechanism 231 is a device that can absorb and move the packaging bag. For example, the lower vacuum bag transfer mechanism 231 can include a suction device and a moving device that drives 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.

[0062] The lower driving part 232 is a device that can provide power to the lower vacuum bag transfer mechanism 231 so that the lower vacuum bag transfer mechanism 231 can move the packaging bag. For example, the lower driving part 232 can be a DC motor, an AC motor, etc., but is not limited thereto.

[0063] In this way, the other side of the packaging bag is adsorbed onto the lower vacuum bag transfer mechanism 231 by the lower vacuum bag transfer mechanism 231, and then the lower driving unit 232 provides power for the lower vacuum bag transfer mechanism 231 so that the lower vacuum bag transfer mechanism 231 can move the packaging bag from the narrow end of the conical gap to the wide end of the conical gap, and by inclining the packaging bag transportation direction of the lower vacuum bag transfer mechanism 231 with the packaging bag transportation direction of the upper conveyor belt 2233, the bag mouth of the packaging bag can be automatically opened in the process of moving the packaging bag from the narrow end of the conical gap to the wide end of the conical gap.

[0064] In some embodiments, please refer to Figure 3 and Figure 4 The lower vacuum bag transfer mechanism 231 includes a lower vacuum part 2311, a lower auxiliary rotating shaft 2312, a lower conveyor belt 2313 and a lower suction member 2314.

[0065] The lower vacuum part 2311 is arranged on the bag feeding fixing plate 21 and is located directly below the upper vacuum part 2231. A lower vacuum containing space is arranged inside the lower vacuum part 2311. A lower vent hole connected to the upper vacuum containing space is opened on one side of the lower vacuum part 2311 close to the upper suction transfer device 22.

[0066] The lower auxiliary rotating shaft 2312 is rotatably disposed on the bag feeding fixing plate 21 and is located at an end of the lower vacuum portion 2311 away from the lower driving portion 232 .

[0067] The lower conveyor belt 2313 can be transmission-disposed on the power output shaft of the lower driving part 232 and the lower auxiliary rotating shaft 2312 and surround the lower vacuum part 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 that a conical gap is formed between the lower conveyor belt 2313 and the upper conveyor belt 2233. A plurality of lower adsorption holes corresponding to the lower air holes of the lower vacuum part 2311 are provided on the lower conveyor belt 2313. The lower adsorption holes can be connected with the lower vacuum containing space through the lower air holes. The lower conveyor belt 2313 is used to drive the packaging bags to move.

[0068] The lower vacuum member 2314 is disposed on the lower vacuum portion 2311 and communicates with the lower vacuum containing space, and is used to extract air in the lower vacuum containing space to provide adsorption force so that the packaging bag is continuously adsorbed on the lower conveyor belt 2313 .

[0069] The length of the lower vacuum part 2311 is smaller than that of the upper vacuum part 2231 so that the packaging bag will not contact the lower conveyor belt 2313 surrounding the lower vacuum part 2311 during the process of moving the packaging bag by the bag suction device 24 .

[0070] It can be understood that the lower vacuum part 2311 is a plate-like structure with a lower vacuum containing space inside, which can limit the moving direction of the packaging bag. For example, the lower vacuum part 2311 can be a plastic hollow plate, an aluminum hollow plate, etc., but is not limited thereto.

[0071] 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 may include a fixed rod and a rotating part, but is not limited thereto, wherein one end of the fixed rod is connected to the bag feeding fixed plate 21, the rotating part is rotatably arranged at the other end of the fixed rod away from the bag feeding fixed plate 21, and the lower conveyor belt 2313 is rotatably arranged on the rotating part, the fixed rod is a rod-shaped structure, for example, the fixed rod can be a copper fixed rod, an aluminum fixed rod, etc., but is not limited thereto, and 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.

[0072] The lower conveyor belt 2313 is a belt-shaped structure, and a plurality of lower adsorption holes are provided on the lower conveyor belt 2313, which are opposite to the upper vent holes of the lower vacuum part 2311, so that the lower vacuum storage space of the lower vacuum part 2311 can be connected with the lower adsorption holes provided on 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 that a conical gap is formed between the lower conveyor belt 2313 and the upper conveyor belt 2233.

[0073] The lower suction member 2314 is a device capable of extracting air from the lower vacuum accommodation space of the lower vacuum portion 2311. For example, the lower suction member 2314 may be an electric vacuum compression bag suction pump, a small rotary vane vacuum pump, etc., but is not limited thereto.

[0074] With such arrangement, when the other side of the packaging bag contacts the lower conveyor belt 2313, the lower suction member 2314 continuously extracts the air in the lower vacuum storage space of the lower vacuum, so that the lower vacuum storage space forms a vacuum, and applies the vacuum suction force to the packaging bag in contact with the lower conveyor belt 2313 through the lower suction holes provided 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 to rotate by the lower driving unit 232 so that the packaging bag can move from the narrow end of the conical gap to the wide end of the conical gap. By the packaging bag transportation direction of the lower conveyor belt 2313 being inclined to the packaging bag transportation direction of the upper conveyor belt 2233, the two sides of the packaging bag forming the bag opening move away from each other in the process of the packaging bag moving from the narrow end of the conical gap to the wide end of the conical gap, so that the bag opening is automatically opened.

[0075] In some embodiments, see Figure 5The bagging device 30 includes a rotating bag transporting device 31 and a loading device 32.

[0076] The rotating bag transport device 31 is used to be set on the mounting plate 10 and is located on the side of the upper suction transfer device 22 away from the bag suction device 24. The rotating bag transport device 31 can be partially located in the conical gap to receive the packaging bags conveyed by the bag feeding device 20 and can be rotated to move the packaging bags located in the conical gap to one side of the packaging device 40.

[0077] The loading device 32 is used to be set on the mounting plate 10. The loading device 32 is located on the side of the rotating bag transport device 31 away from the bag feeding device 20 and below the rotating bag transport device 31. It is used to transport materials into the packaging bag and move the packaging bag containing the materials to the packaging device 40 and vacuum the packaging bag.

[0078] It can be understood that the rotating bag transport device 31 is a device that can be partially located in the conical gap and absorb the packaging bag, and move the absorbed packaging bag from the conical gap to the side of the packaging device 40. For example, the rotating bag transport device 31 can include a suction device and a moving device that drives the suction device to move, the suction device can be a corrugated suction cup, a multi-point vacuum suction cup, etc., but not limited to this, and the moving device can be a driving cylinder, a driving motor, etc., but not limited to this.

[0079] The loading device 32 is a device that can move materials into a packaging bag, move the packaging bag containing materials onto the packaging device 40, and simultaneously evacuate the interior of the packaging bag in the process of moving the packaging bag containing materials onto the packaging device 40. For example, the loading device 32 may include a material moving device for receiving materials and moving the materials to the side of the rotating bag transport device 31 and a vacuum pushing device for moving the materials into the packaging bag on the rotating bag transport device 31 and evacuating the interior of the packaging bag. For example, the material moving device may be a plate chain material hoist, a reciprocating material hoist, etc., but not limited thereto. The vacuum pushing device may include a hollow rod and an exhaust device that can extract air from the channel inside the hollow rod. For example, the hollow rod may be a plastic rod, an aluminum rod, etc., but not limited thereto. The exhaust device may be an electric vacuum compression bag exhaust pump, a small rotary vane vacuum pump, etc., but not limited thereto.

[0080] In this way, after the rotating bag transport device 31 receives the packaging bag delivered by the bag feeding device 20 and moves the received packaging bag to the side of the packaging device 40 by rotating, the loading device 32 moves the material into the packaging bag, and then moves the packaging bag with the material onto the packaging device 40, and evacuates the interior of the packaging bag while moving the packaging bag, and finally seals the bag opening of the packaging bag through the packaging device 40 while evacuating the vacuum, realizing automatic vacuumization and sealing, thereby improving work efficiency.

[0081] Exemplarily, the way in which the rotating bag transport device 31 receives the packaging bag conveyed by the bag feeding device 20 can be that the vacuum adsorption force provided by the rotating bag transport device 31 is greater than the vacuum adsorption force provided by the bag feeding device 20, so that the packaging bag is detached from the bag feeding device 20 and adsorbed on the rotating bag transport device 31; or when the bag mouth of the packaging bag reaches the wide end of the conical gap, the bag feeding device 20 stops providing the vacuum adsorption force so that the packaging bag is detached from the bag feeding device 20, and at the same time, the rotating bag transport device 31 provides the vacuum adsorption force so that the packaging bag is adsorbed on the rotating bag transport device 31, etc., but is not limited to this.

[0082] In some embodiments, please refer to Figures 5 to 7 The rotating bag transport device 31 includes a bag transport device mounting frame 311, a rotating platform 312, a plurality of opening and closing mechanisms 313 and a bagging driving unit 314.

[0083] The bag transport device mounting frame 311 is used to be disposed on the mounting plate 10 and is located at a side of the upper suction and transfer device 22 away from the bag suction device 24 .

[0084] The rotating platform 312 is rotatably disposed on the bag transport device mounting frame 311 and is located between the bag transport device mounting frame 311 and the upper suction transfer device 22. The rotating platform 312 is provided with a plurality of bagging holes penetrating the rotating platform 312, and at least two bagging holes are respectively located on both sides of the rotating platform 312.

[0085] 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. The two opening and closing mechanisms 313 corresponding to the bagging hole can be brought close to or separated from each other to change the opening and closing state of the packaging bag.

[0086] The bagging driving unit 314 is disposed on the bag transporting device mounting frame 311 , and a power output shaft of the bagging driving unit 314 is connected to the rotating platform 312 . The bagging driving unit 314 is used to drive the rotating platform 312 to rotate.

[0087] It can be understood that the bag transport device mounting frame 311 is a support member that can provide support for the rotating platform 312 and the bagging driving unit 314. For example, the material of the bag transport device mounting frame 311 can be copper, aluminum, etc., but is not limited thereto.

[0088] The rotating platform 312 is a rotatable plate-like structure. For example, the rotating platform 312 can be a rectangular plate-like structure, a circular plate-like structure, etc., but is not limited thereto. The rotating platform 312 is provided with at least two bagging holes penetrating the rotating platform 312 .

[0089] For example, when the number of bagging holes is an even number, every two bagging holes with the farthest straight-line distance are symmetrical about the center point of the rotating platform 312. When the number of bagging holes is an odd number and the rotating platform 312 is a circular plate-like structure, a ray is drawn from the center of the rotating platform 312 to the center of each bagging hole, and the ray can divide the rotating platform 312 into equal parts.

[0090] 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 absorb or not absorb the packaging bag. For example, the opening and closing mechanism 313 can include a suction device for absorbing or not absorbing the packaging bag and a rotation drive 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 not limited to this. The rotation drive device can be a drive cylinder, a drive motor, etc., but not limited to this. Every two opening and closing mechanisms 313 are arranged opposite to each other and are respectively located on both sides of the bagging hole, so that the ends of the two opening and closing mechanisms 313 away from the rotating platform 312 can approach or move away from each other, thereby closing or opening a part of the packaging bag absorbed on the opening and closing mechanism 313.

[0091] For example, when two bagging holes are provided on the rotating 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 of the two bagging holes. The ends of the two opening and closing mechanisms 313 corresponding to the bagging holes that are away from the bagging holes can be close to each other or away from each other.

[0092] Exemplarily, when three bagging holes are provided on the rotating 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 remaining two opening and closing mechanisms 313 correspond to the last remaining bagging hole.

[0093] The bagging driving unit 314 is a device that can drive the rotating platform 312 to rotate. For example, the bagging driving unit 314 can be a DC motor, an AC motor, etc., but is not limited thereto.

[0094] In this way, the two opening and closing mechanisms 313, which are partially located in the conical gap and partially 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, and then the bagging drive unit 314 drives the rotating platform 312 to rotate, thereby driving the opening and closing mechanism 313 to rotate, so that the packaging bag adsorbed on the opening and closing mechanism 313 leaves the conical gap and moves to the side of the packaging device 40.

[0095] Optionally, the ends of the two opening and closing mechanisms 313 corresponding to the bagging holes and partially located in the conical gap away from the rotating platform 312 are in a state of being close to each other, so that the two opening and closing mechanisms 313 corresponding to the bagging holes can be partially located in the packaging bag, and the ends of the two opening and closing mechanisms 313 corresponding to the bagging holes and located beside the packaging device 40 away from the rotating platform 312 are in a state of being far away from each other, so that the materials can smoothly enter the packaging bag. When the bagging drive unit 314 drives the rotating platform 312 to rotate, the two ends of the two opening and closing mechanisms 313 corresponding to the bagging holes and partially located in the conical gap, which are close to each other in 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 drive unit 314 stops driving the rotating platform 312 to rotate and is located beside the packaging device 40. When the bagging drive unit 314 drives the rotating platform 312 to rotate, if the two opening and closing mechanisms 313 corresponding to the bagging holes and not located in the conical gap are located in the conical gap when the rotating platform 312 stops rotating, the two opening and closing mechanisms 313 corresponding to the bagging holes will move closer to each other at one end away from the rotating platform 312 during the rotation process, so that the two opening and closing mechanisms 313 corresponding to the bagging holes can be smoothly located in the conical space. When the bagging drive unit 314 stops driving the rotating platform 312 to rotate, there must be a group of two opening and closing mechanisms 313 corresponding to the bagging holes located in the conical gap, and there must be a group of two opening and closing mechanisms 313 corresponding to the bagging holes located beside the packaging device 40.

[0096] In some embodiments, please refer to Figures 5 to 7 The opening and closing mechanism 313 includes an opening and closing fixing plate 3131, an opening and closing cylinder 3132 and an opening and closing air extraction device 3133.

[0097] The opening and closing fixing plate 3131 can be rotatably arranged on the rotating platform 312 and corresponds to the position of the bagging hole. The opening and closing fixing plate 3131 can be partially located in the conical gap. The two opening and closing fixing plates 3131 corresponding to the bagging holes can be brought closer to or separated from each other to change the opening and closing state of the packaging bag. An opening and closing accommodating space is provided inside the opening and closing fixing plate 3131, and an opening and closing ventilation hole connected to the opening and closing accommodating space is provided on the opening and closing fixing plate 3131.

[0098] The opening and closing cylinder 3132 is arranged on the rotating platform 312 and the power output end of the opening and closing cylinder 3132 is hinged to the opening and closing fixed plate 3131. The opening and closing cylinder 3132 is used to change the rotation angle of the opening and closing fixed plate 3131 so that the two opening and closing fixed plates 3131 corresponding to the bagging holes can move closer to or apart from each other.

[0099] The opening and closing air extraction device 3133 is arranged on one side of the opening and closing fixing plate 3131 close to the rotating platform 312. The opening and closing air extraction device 3133 is connected to the opening and closing accommodating space and is used to extract air in the opening and closing accommodating space to provide adsorption force so that the packaging bag is adsorbed on the opening and closing fixing plate 3131.

[0100] It can be understood that the opening and closing fixing plate 3131 is a plate-like structure with an opening and closing accommodation space provided therein, and a plurality of opening and closing vents communicating with the opening and closing accommodation space are provided on the opening and closing fixing plate 3131, and one end of the opening and closing fixing plate 3131 is rotatably disposed on the rotating platform 312. For example, the material of the opening and closing fixing plate 3131 can be copper, aluminum, etc., but is not limited thereto.

[0101] The opening and closing cylinder 3132 is a mechanism that can drive the rotation of the opening and closing fixed plate 3131. For example, the opening and closing cylinder 3132 can be an electric cylinder, a piston cylinder, etc., but is not limited thereto. By hingedly connecting the opening and closing fixed plate 3131 to the power output end of the opening and closing cylinder 3132, the opening and closing fixed plate 3131 can be rotated within a certain range while maintaining the stability of the connection.

[0102] 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.

[0103] With such arrangement, the air in the opening and closing accommodation space is continuously extracted by the opening and closing air extraction device 3133 to form a vacuum in the opening and closing accommodation space, and then the vacuum adsorption force is applied to the packaging bag in contact with the opening and closing fixing plate 3131 through the opening and closing vent holes provided on the opening and closing fixing plate 3131, so that the packaging bag is firmly adsorbed on the opening and closing fixing plate 3131. The opening and closing cylinder 3132 drives the opening and closing fixing plate 3131 to rotate so that the ends of the two opening and closing fixing plates 3131 corresponding to the bagging holes away from the rotating platform 312 are close to each other so that the two opening and closing fixing plates 3131 corresponding to the bagging holes can be partially located in the conical gap, or the ends of the two opening and closing fixing plates 3131 corresponding to the bagging holes away from the rotating platform 312 are separated from each other so that the bag body of the packaging bag is opened, so that the material can smoothly enter the interior of the packaging bag.

[0104] 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 .

[0105] The lifting device 321 is used to be set on the mounting plate 10. The lifting device 321 is located below the bag transport device mounting frame 311 and on the side of the rotating platform 312 away from the bag feeding device 20. It is used to change the height of the material so that the material can be at the same height as the bagging hole.

[0106] The first pushing device 322 is used to be disposed on the mounting plate 10 and is located at a side of the lifting device 321 away from the rotating platform 312 . The first pushing device 322 is used to move materials onto the lifting device 321 .

[0107] The second pushing device 323 is used to be set on the mounting plate 10 and is located above the first pushing device 322. The second pushing device 323 corresponds to the position of the lowest bagging hole among the multiple bagging holes opened on the rotating platform 312. It is used to push the material from the lifting device 321 into the packaging bag through the bagging hole and move the packaging bag containing the material to the packaging device 40, while extracting the air in the packaging bag.

[0108] It can be understood that the lifting device 321 is a device that can receive materials and change the height of the materials so that the materials are located 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.

[0109] The first pushing device 322 is a device that can push materials to move the materials onto the lifting device 321. For example, the first pushing device 322 can be a hydraulic pushing device, a pneumatic pushing device, etc., but is not limited thereto.

[0110] The second pushing device 323 is a device that can push the material on the lifting device 321 into the packaging bag, push the packaging bag containing the material onto the packaging device 40, and evacuate the packaging bag during the pushing process. For example, the second pushing device 323 may include a vacuum pushing device for pushing the material into the packaging bag, pushing the packaging bag containing the material onto the packaging 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 may include a hollow rod and an exhaust device that can extract the air in the channel inside the hollow rod. For example, the hollow rod may be a plastic rod, an aluminum rod, etc., but not limited thereto. The exhaust device may be an electric vacuum compression bag exhaust pump, a small rotary vane vacuum pump, etc., but not limited thereto. The moving mechanism may be a driving cylinder, a driving motor, etc., but not limited thereto.

[0111] With such arrangement, the material is moved to the lifting device 321 at the same height as the first pushing device 322 through the first pushing device 322, and then the height of the material is raised by the pushing device so that the material is at the same height as the second pushing device 323, and finally the material on the pushing device is moved to the packaging belt adsorbed by the opening and closing mechanism 313 through the second pushing device 323, and the material is continuously pushed so that the material presses against the packaging bag so that the packaging bag is separated from the opening and closing mechanism 313 and moved to the packaging device 40, and at the same time, the second pushing device 323 continuously draws a vacuum inside the packaging bag so that the packaging bag is in a vacuum state when it is moved to the packaging device 40, thereby improving work efficiency.

[0112] In some embodiments, please refer to Figures 8 to 9 The second pushing device 323 includes a moving mechanism 3231 and a vacuum pushing mechanism 3232 .

[0113] The moving mechanism 3231 is used to be disposed on the mounting plate 10 and is located above the first pushing device 322 , and is located on a side of the rotating platform 312 away from the bag feeding device 20 .

[0114] The vacuum pushing mechanism 3232 is arranged on the moving mechanism 3231 and corresponds to the position of the lowest bagging hole among the multiple bagging holes opened on the rotating platform 312; the moving mechanism 3231 is used to drive the vacuum pushing mechanism 3232 to move, so that the vacuum pushing mechanism 3232 pushes the material from the lifting device 321 through the bagging hole into the packaging bag and moves the packaging bag containing the material to the packaging device 40, while extracting the air in the packaging bag.

[0115] It can be understood that the moving mechanism 3231 is a mechanism that can drive the vacuum pushing mechanism 3232 to reciprocate. For example, the moving mechanism 3231 can be a gear rack mechanism, a connecting rod mechanism, etc., but is not limited thereto.

[0116] The vacuum pushing mechanism 3232 is a mechanism that can push the material from the lifting device 321 into the packaging bag through the bagging hole and move the packaging bag containing the material to the packaging device 40, while extracting the air in the packaging bag. For example, the vacuum pushing mechanism 3232 can include a hollow rod and an exhaust device that can extract the air in the channel inside the hollow rod. For example, the hollow rod can be a plastic rod, an aluminum rod, etc., but not limited to this. The exhaust device can be an electric vacuum compression bag exhaust pump, a small rotary vane vacuum pump, etc., but not limited to this.

[0117] In this way, the vacuum pushing mechanism 3232 is driven by the moving mechanism 3231 to move the material into the packaging bag, and the packaging bag containing the material is moved to the packaging device 40. The vacuum pushing mechanism 3232 simultaneously extracts the air in the packaging bag during the process of moving the packaging bag to form a vacuum in the packaging bag, thereby improving work efficiency.

[0118] In some embodiments, see Figures 9 and 10 The vacuum pushing mechanism 3232 includes a pushing fixing block 32321, a pushing rod 32322, a pushing shell 32323, an exhaust pipe 32324, an exhaust spring 32325 and a pushing shell exhaust device 32326.

[0119] The pushing fixed block 32321 is arranged on the moving mechanism 3231 .

[0120] One end of the push rod 32322 is connected to the cargo pushing fixing block 32321 .

[0121] The push shell 32323 is disposed at the other end of the push rod 32322 . The push shell 32323 has a push shell 32323 accommodating space therein, and a push shell 32323 groove is disposed on the surface of the push shell 32323 .

[0122] The exhaust pipe 32324 is rotatably disposed on the push shell 32323 and is partially located in the groove of the push shell 32323 . The exhaust pipe 32324 is a hollow pipe, and the pipeline formed in the exhaust pipe 32324 is connected to the accommodating space of the push shell 32323 .

[0123] One end of the air exhaust spring 32325 is connected to the air exhaust pipe 32324, and the other end of the air exhaust spring 32325 is connected to the push shell 32323 and is located in the groove of the push shell 32323. The air exhaust spring 32325 is used to change the position of the air exhaust pipe 32324 so that the air exhaust pipe 32324 can be partially located in the groove of the push shell 32323 without being affected by external force.

[0124] The shell pushing and exhausting device 32326 is disposed on the shell pushing 32323 and is in communication with the accommodating space of the shell pushing 32323 , and is used for extracting air in the packaging bag through the exhaust pipe 32324 .

[0125] It can be understood that the pusher fixing block 32321 is a block-shaped connector for connecting the push rod 32322 and the moving mechanism 3231. For example, the material of the pusher fixing block 32321 can be plastic, aluminum, etc., but is not limited thereto.

[0126] The push rod 32322 is a rod-shaped structure, which 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.

[0127] The push shell 32323 is a shell-like structure. For example, the push shell 32323 can be an aluminum shell, a plastic shell, etc., but is not limited to this.

[0128] The air extraction pipe 32324 is a tubular structure, and the air extraction pipe 32324 is connected to the accommodating space of the push shell 32323, and is used to extract the air in the packaging bag. For example, the air extraction pipe 32324 can be an aluminum tube, a plastic tube, etc., but is not limited thereto.

[0129] 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 push shell 32323 and 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.

[0130] The shell-pushing and exhausting device 32326 is a device that can continuously extract the air in the accommodation space of the shell-pushing and exhausting device 32323. For example, the shell-pushing and exhausting device 32326 can be an electric vacuum compression bag exhaust pump, a small rotary vane vacuum pump, etc., but is not limited thereto.

[0131] In this way, when the material is located beside the bagging hole, the moving mechanism 3231 drives the pushing fixed block 32321 to move, and the pushing fixed block 32321 drives the push rod 32322 to move, thereby driving the push shell 32323 close to the packaging bag, so that the material passes through the bagging hole and is located in the packaging bag adsorbed on the opening and closing mechanism 313, and is located between the two opening and closing mechanisms 313 corresponding to the bagging hole. Then, the moving mechanism 3231 continues to drive the push shell 32323 to move toward the packaging device 40, so that the push shell 32323 3 drives the material in the packaging bag to move toward the packaging device 40 together with the packaging bag. At the same time, the shell pushing and exhausting device 32326 continuously extracts the air in the packaging bag through the exhaust pipe 32324 which is connected to the accommodating space of the shell pushing 32323 and located inside the packaging bag to form a vacuum inside the packaging bag. When the packaging bag is located on the packaging device 40, the moving mechanism 3231 adjusts the position of the shell pushing 32323 so that the shell pushing 32323 is located outside the packaging bag and the exhaust 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 32323 away from the packaging bag and passes through the bagging hole so that the rotating platform 312 can rotate normally.

[0132] In some embodiments, see Fig.11 The packaging device 40 includes a sealing device 41, a packaging conveying device and a packaging pushing device 43.

[0133] The sealing device 41 is disposed on the mounting plate 10 and is used to seal the opening of the packaging bag.

[0134] The packaging conveyor 42 is used to receive and move the packaging bags filled with materials transported by the loading device 32.

[0135] The packing pushing device 43 is disposed on the packing conveying device 42 and is used to move the packing bags containing materials on the packing conveying device 42 .

[0136] It can be understood that the sealing device 41 is a device that can seal a packaging bag containing materials. For example, the sealing device 41 can be a fully automatic rolling sealer, a heating sealer, etc., but is not limited thereto.

[0137] The packing conveyor 42 is a device that can move the packaging bag containing the material. For example, the packing conveyor 42 can be a roller conveyor, a chain conveyor, etc., but is not limited thereto.

[0138] The packing push device 43 is a device that can translate the packaging bag containing materials as a whole. For example, the packing push device 43 may include a packing power unit, a packing push plate, etc., but is not limited thereto. The packing power unit is a mechanism that can drive 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 that can drive 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.

[0139] With such arrangement, when the packaging bag containing materials is located on the packaging conveying device 42, the packaging pushing device 43 pushes the packaging bag containing materials close to the sealing device 41 and makes the bag opening of the packaging bag located in the sealing device 41. At the same time, in the process of the packaging pushing device 43 pushing the packaging bag containing materials, the exhaust pipe 32324 receives the thrust of the packaging pushing device 43 so that the exhaust pipe 32324 approaches the groove of the pushing shell 32323 and compresses the exhaust spring 32325. When the bag opening of the packaging bag is completely located in the sealing device 41, the exhaust pipe 32324 is completely located in the groove of the pushing shell 32323. When the sealing device 41 completes the sealing operation on the bag mouth of the packaging bag, the packaging conveying device 42 drives the sealed bag away from the sealing device 41 and outputs the packaging bag containing the material, and the packaging pushing device 43 is reset so that the packaging pushing device 43 can continue to push the packaging bag containing the material so that the packaging bag containing the material is close to the sealing device 41. At the same time, the air extraction spring 32325 squeezed by the packaging pushing device 43 releases the compressed elastic force during the resetting process of the packaging pushing device 43, so that the air extraction pipe 32324 partially leaves the groove of the push shell 32323.

[0140] The present application also provides a push-type bag-feeding packaging machine 1000, see Fig.12 The horizontal push-type bag-feeding packaging machine 1000 includes a housing 1100 and a plurality of transport devices 1200 .

[0142] A plurality of transport devices 1200 are partially located in the housing accommodation space, and are used to transport packaging bags or materials to the bagging and packaging mechanism 100 , or to receive packaging bags containing materials output by the bagging and packaging mechanism 100 and move the packaging bags containing materials away from the bagging and packaging mechanism 100 .

[0143] The mounting plate 10 of the bagging and packaging mechanism 100 is arranged on the casing 1100 and is located in the casing accommodating space. The bag feeding device 20 of the bagging and packaging mechanism 100 is arranged on the mounting plate 10 and is located in the casing accommodating space, and the bag suction device 24 of the bag feeding device 20 is located above at least one transportation device 1200.

The packaging device 40 of the bagging and packaging mechanism 100 is arranged on the casing 1100 and is partially located in the casing accommodating space, and the packaging device 40 is partially located beside at least one transportation device 1200.

[0144] It can be understood that the housing 1100 is a shell having a housing accommodating space inside and capable of protecting internal devices or mechanisms. For example, the housing 1100 can be an aluminum shell, a stainless steel shell, etc., but is not limited thereto.

[0145] 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.

[0146] From the above, it can be seen that the push-type bag-feeding packaging machine 1000 provided in the embodiment of the present application can move the packaging bag to the bottom of the bag suction device 24, move the material to the side of the lifting device 321, and output the sealed packaging bag.
