[0093] The guide exhaust assembly 700 can be configured into various modules according to different production capacities, such as a first guide exhaust assembly 7100 and a second guide exhaust assembly 7200, which increase sequentially according to production capacity. The first guide exhaust assembly 7100 can preferably be a guide exhaust assembly with a production capacity of 0 to 500 packs per hour (i.e., a guide exhaust assembly with a production capacity of 300 / 500 packs / hour). The second guide exhaust assembly 7200 can preferably be a guide exhaust assembly with a production capacity of 0 to 800 packs per hour (i.e., a guide exhaust assembly with a production capacity of 800 packs / hour).

[0094] The bag-holding assembly 800 can be configured into various modules according to different production capacities, such as a first bag-holding assembly 8100 and a second bag-holding assembly 8200, which increase sequentially according to production capacity. The first bag-holding assembly 8100 is preferably a bag-holding assembly with a production capacity of 0 to 500 bags per hour (i.e., a bag-holding assembly with a production capacity of 300 / 500 bags / hour). The second bag-holding assembly 8200 is preferably a bag-holding assembly with a production capacity of 0 to 800 bags per hour (i.e., a bag-holding assembly with a production capacity of 800 bags / hour).

[0095] Here, the frame component 400 and the lifting component 500 remain unchanged, serving as the basic platform for functional construction. The bag supply component 200, bag picking component 300, guide and exhaust component 700, and bag holding component 800 are configured according to production capacity requirements to meet, but are not limited to, 300 packs / hour (meaning a production capacity of 0 to 300 packs per hour), 500 packs / hour (meaning a production capacity of 0 to 500 packs per hour), and 800 packs / hour (meaning a production capacity of 0 to 800 packs per hour).

[0096] like Figure 5 As shown, the bag storage assembly 100 of this invention includes a bag storage frame 101, a bag pushing cylinder 102, a bag loading station 103, a bag storage station 104, an end adjusting baffle 105, a tail adjusting baffle 106, a lifting and pushing bag assembly 107, a lifting cylinder 108, and an adjusting assembly 109. The bag loading station 103 and the bag storage station 104 serve as two bag storage stations and are located on the upper surface of the bag storage frame 101. The end adjusting baffle 105 and the tail adjusting baffle 106 are slidably connected to the front and rear ends of the upper surface of the bag storage frame 101, respectively.

[0097] The lifting and pushing bag assembly 107 is installed on the upper surface of the bag storage frame 101, located below the bag storage station. The piston rod of the pushing bag cylinder 102 is connected to the lifting and pushing bag assembly 107, for example, the lifting and pushing bag assembly 107 is connected to the piston rod of the pushing bag cylinder 102 through a self-aligning connector.

[0098] The cylinder body, end adjusting baffle 105, and tail adjusting baffle 106 of the bag pushing cylinder 102 are connected to the adjusting assembly 109, which is mounted on the bag storage frame 101 and located below the upper surface of the bag storage frame 101. Rotating the handwheel of the adjusting assembly 109 causes the lifting bag pushing assembly 107 to move in the same direction as the tail adjusting baffle 106 and in the opposite direction to the end adjusting baffle 105, to accommodate different packaging bag widths.

[0099] The bag loading station 103 and the bag storage station 104 are equipped with detection elements to determine whether there are any remaining packaging bags at the station. When the bag loading station 103 detects that the packaging bags are used up, the lifting cylinder 108 drives the push rod in the lifting and pushing bag assembly 107 to descend. Under the action of the push rod cylinder 102, the push rod moves from below the packaging bag to the push position at the tail adjustment baffle 106. The lifting cylinder 108 then drives the push rod in the lifting and pushing bag assembly 107 to rise, and the push rod cylinder 102 pushes the packaging bag from the bag storage station 104 to the bag loading station 103. Adjusting the position of the end adjustment baffle 105, the tail adjustment baffle 106, and the push rod position adjustment handwheel allows the bag storage to accommodate packaging bags of different widths.

[0100] like Figure 6As shown, the bag supply assembly 200 in this invention can preferably be a first bag supply assembly 2100, including a first frame 2101, a bag taking cylinder 2102, a bag feeding cylinder 2103, a first vacuum system 2104, a bag holding assembly 2105, a first bag taking assembly 2106, a bag opening assembly 2107, and a bag opening cylinder 2108.

The bag-picking cylinder 2102 and the bag-feeding cylinder 2103 are installed on one side of the first frame 2101 (e.g., the upper right side). The first bag-picking assembly 2106 is installed on the upper part of the first frame 2101 and connected to the bag-picking cylinder 2102 and the bag-feeding cylinder 2103 (e.g., using a spherical bearing connection). The bag-picking cylinder 2102 drives the first bag-picking assembly 2106 to move up and down along the first frame 2101.

[0102] The bag-holding assembly 2105 is installed inside the first frame 2101 (e.g., the inner right side) and is used to move back and forth along the first frame 2101 to hold the opening of the packaging bag. The bag-opening assembly 2107 is located below the first bag-removing assembly 2106. The bag-opening cylinder 2108 is fixed on the first frame 2101 (e.g., the front side) and connected to the bag-opening assembly 2107.

[0103] The first bag feeding assembly 2100 is interlocked with the bag storage assembly 100. When there is a packaged bag at the bag feeding station 103, the first vacuum system 2104 is activated. The bag picking cylinder 2102 drives the first bag picking assembly 2106 to descend, pick up the packaged bag, and then rise. The bag supporting assembly 2105 moves forward to support the bag opening, while the bag feeding cylinder 2103 drives the first bag picking assembly 2106 to move the packaged bag to the bag opening station. The bag supporting assembly 2105 moves backward, and the bag opening cylinder 2108 drives the bag opening assembly 2107 to rise, pick up the bag opening on the other side, and then descend to open the bag opening, completing the bag opening action.

[0104] like Figure 7 As shown, the bag supply assembly 200 in this invention can preferably be a second bag supply assembly 2200, including a second frame 2201, a first rear bag pressing assembly 2202, a second bag taking assembly 2203, a second vacuum system 2204, a bag transferring cylinder 2205, a first bag forming mechanism 2206, a first front bag pressing assembly 2207, a first upper bag suction assembly 2208, a first bag opening position 2209, a first lower bag suction assembly 2210, and a first bag delivery mechanism 2211.

[0105] The second frame 2201 is divided into upper and lower layers by a single plate. The second vacuum system 2204 is arranged in the lower layer of the second frame 2201, for example, the vacuum pump of the second vacuum system 2204 is arranged in the lower layer of the second frame 2201. The first rear bag pressing assembly 2202 and the first front bag pressing assembly 2207 are fixed to the front and rear ends of the upper layer of the second frame 2201, and the first bag-forming mechanism 2206 is mounted on the plate.

[0106] The first bag feeding mechanism 2211 is installed below the first front-pressing bag assembly 2207, and the second bag taking assembly 2203 is installed on the side of the second frame 2201 (e.g., Figure 7 (On the left side of the middle), the piston rod of the bag transfer cylinder 2205 is rotatably connected (e.g., hinged) to the second bag taking assembly 2203, and the cylinder body is fixed on the second frame 2201.

[0107] The first bag opening position 2209 is located at the front end of the second frame 2201, and the first upper suction bag assembly 2208 and the first lower suction bag assembly 2210 are respectively installed above and below the first bag opening position 2209.

[0108] The second bag supply assembly 2200 is interlocked with the bag storage assembly 100. When there is a packaged bag at the bag loading station 103, the second vacuum system 2204 is activated, the second bag picking assembly 2203 descends, uses vacuum negative pressure to suck up the packaged bag and then rises. The bag transfer cylinder 2205 drives the second bag picking assembly 2203 to move horizontally above the first bag assembly mechanism 2206, the second vacuum system 2204 stops, and the packaged bag is placed into the first bag assembly mechanism 2206.

[0109] The bag-moving cylinder 2205 drives the second bag-picking assembly 2203 back to its original position to repeat the bag-picking process. The first bag-forming mechanism 2206 positions and shapes the packaging bag. The first rear bag-pressing assembly 2202 and the first front bag-pressing assembly 2207 descend to press the packaging bag. The first bag-feeding mechanism 2211 starts and uses friction to send the packaging bag to the first bag-opening position 2209. The first upper bag-suction assembly 2208 descends to press the packaging bag opening. The second vacuum system 2204 starts. The first upper bag-suction assembly 2208 and the first lower bag-suction assembly 2210 use vacuum negative pressure to suck up the upper and lower sides of the packaging bag opening. The first upper bag-suction assembly 2208 rises to open the packaging bag opening, and the bag-opening action is completed.

[0110] like Figure 8As shown, the bag supply assembly 200 in this invention can preferably be a third bag supply assembly 2300, including a third frame 2301, a third bag picking assembly 2302, a third vacuum system 2303, a second rear bag pressing assembly 2304, a bag clamping assembly 2305, a bag transferring assembly 2306, a second bag forming mechanism 2307, a second front bag pressing assembly 2308, a second upper bag suction assembly 2309, a second bag opening position 2310, a second lower bag suction assembly 2311, and a second bag delivery mechanism 2312.

[0111] The third frame 2301 is divided into upper and lower layers by a single plate. The third vacuum system 2303 is arranged in the lower layer of the third frame 2301, for example, the vacuum pump of the third vacuum system 2303 is arranged in the lower layer of the third frame 2301. The second rear bag pressing assembly 2304 and the second front bag pressing assembly 2308 are fixed to the front and rear ends of the upper layer of the third frame 2301, and the second bag-forming mechanism 2307 is installed on the plate.

[0112] The second bag feeding mechanism 2312 is installed below the second front pressing bag assembly 2308, the third bag taking assembly 2302 is installed on the side of the third frame 2301 (for example, the left side shown in the figure), the bag clamping assembly 2305 is fixed on the bag transferring assembly 2306, close to the third bag taking assembly 2302, and the bag transferring assembly 2306 is installed in the upper layer of the third frame 2301.

[0113] The second bag opening position 2310 is located at the front end of the third frame 2301, and the second upper suction bag assembly 2309 and the second lower suction bag assembly 2311 are respectively installed above and below the second bag opening position 2310.

[0114] The third bag supply assembly 2300 is interlocked with the bag storage assembly 100. When there is a packaged bag at the bag loading station 103, the third vacuum system 2303 is activated, the third bag picking assembly 2302 descends, uses vacuum negative pressure to suck up one side of the packaged bag and then rises, the bag clamping assembly 2305 clamps the side of the packaged bag, the third vacuum system 2303 stops, and the bag transfer assembly 2306 drives the bag clamping assembly 2305 to move horizontally above the second bag filling mechanism 2307.

[0115] At this time, the third bag-picking component 2302 descends synchronously to pick up the bag, the bag clamping component 2305 releases and puts the packaging bag into the second bag-forming mechanism 2307, the bag-moving component 2306 drives the bag clamping component 2305 back to its original position to clamp the packaging bag again, the second bag-forming mechanism 2307 positions and shapes the packaging bag, the second rear bag-pressing component 2304 and the second front bag-pressing component 2308 descend and press the packaging bag, the second bag-feeding mechanism 2312 starts and uses friction to send the packaging bag to the second bag-opening position 2310, the second upper bag-suction component 2309 descends and presses the packaging bag opening, the third vacuum system 2303 starts, the second upper bag-suction component 2309 and the second lower bag-suction component 2311 use vacuum negative pressure to suck the upper and lower sides of the packaging bag opening, the second upper bag-suction component 2309 rises and opens the packaging bag opening, and the bag-opening action is completed.

[0116] like Figure 9 As shown, the bag-picking assembly 300 in this invention can preferably be a first bag-picking assembly 3100, including a first fixing frame 3101, a plurality of first bearing seats 3102, a plurality of first rotating shafts 3103, a first synchronous connecting rod 3104, a first left support rod 3105, a first bag-supporting cylinder 3106, a first right support rod 3107, a support seat 3108, a bag-picking cylinder 3109, and a connecting rod 3110.

[0117] The first fixing frame 3101 and the support seat 3108 are fixed inside the frame assembly 400. The first bearing seat 3102 is fixed on both sides of the first fixing frame 3101. The first rotating shaft 3103 is supported by the corresponding two end bearing seats 3102. One end of the bag-picking cylinder 3109 is connected to the support seat 3108 (e.g., hinged), and the other end is connected to the first rotating shaft 3103 (e.g., hinged) through the connecting rod 3110.

[0118] The first left support rod 3105 and the first right support rod 3107 are respectively rotatably connected to the corresponding first rotating shaft 3103 (e.g., hinged, and can rotate around the hinge point), the two ends of the first synchronous connecting rod 3104 are respectively rotatably connected to the first left support rod 3105 and the first right support rod 3107 (e.g., hinged), and the two ends of the first bag-supporting cylinder 3106 are respectively rotatably connected to the first left support rod 3105 and the first right support rod 3107 (e.g., hinged).

[0119] Here, the bag-picking cylinder 3109 can preferably be a back-to-back long and short double-stroke cylinder, and the first bag-supporting cylinder 3106 can preferably be a back-to-back long and short double-stroke cylinder.

[0120] When the initial waiting position bag picking cylinder 3109 extends, the first bag supporting cylinder 3106 is in the retracted state. After the bag feeding assembly 200 completes the bag opening action, the bag picking cylinder 3109 retracts, the first rotating shaft 3103 rotates around the first bearing seat 3102, driving the end support rods of the first left support rod 3105 and the first right support rod 3107 to insert into the open packaging bag.

[0121] The long-stroke cylinder of the first bag-supporting cylinder 3106 extends, and the first left support rod 3105 and the first right support rod 3107 open and straighten the opening of the packaging bag. At this time, the negative pressure of the bag supply assembly 200 is closed. After the equipment sends a signal that the bag can be loaded, the long-stroke cylinder of the bag-picking cylinder 3109 extends, driving the first rotating shaft 3103 to rotate 90°, and putting the packaging bag into the bag clamping assembly 600. The long-stroke cylinder of the first bag-supporting cylinder 3106 retracts, and at the same time, the short-stroke cylinder of the bag-picking cylinder 3109 extends, and the first left support rod 3105 and the first right support rod 3107 are lifted upwards and disengaged from the opening of the packaging bag. The long-stroke and short-stroke cylinders of the first bag-supporting cylinder 3106 extend completely, the long-stroke cylinder of the bag-picking cylinder 3109 retracts back to the initial position, and the long-stroke and short-stroke cylinders of the first bag-supporting cylinder 3106 retract completely, and the bag-picking process is repeated.

[0122] like Figure 10 As shown, the bag-picking assembly 300 in this invention can preferably be a second bag-picking assembly 3200, which includes a second fixing frame 3201, a second bearing seat 3202, multiple second rotating shafts 3203, a second synchronous connecting rod 3204, a second left support rod 3205, a second bag-supporting cylinder 3206, a second right support rod 3207, and a bag-picking motor 3208.

[0123] The second fixing frame 3201 is fixed inside the frame assembly 400, the second bearing seat 3202 is fixed on both sides of the second fixing frame 3201, and the second rotating shaft 3203 passes through the corresponding two ends of the second bearing seat 3202 to support the bag picking motor 3208. The bag picking motor 3208 is fixed on one side of the second fixing frame 3201.

[0124] The second left support rod 3205 and the second right support rod 3207 are respectively rotatably connected to the corresponding second rotating shaft 3203 (e.g., hinged, and can rotate around the hinge point). The two ends of the second synchronous connecting rod 3204 are respectively rotatably connected to the second left support rod 3205 and the second right support rod 3207 (e.g., hinged). The two ends of the second bag-supporting cylinder 3206 are respectively rotatably connected to the second left support rod 3205 and the second right support rod 3207 (e.g., hinged).

[0125] The second bag-supporting cylinder 3206 here can preferably be a back-to-back long and short double-stroke cylinder.

[0126] The second bag-picking assembly 3200 is characterized by being driven to rotate by the bag-picking motor 3208, compared to the first bag-picking assembly 3100, thus achieving a faster bag-picking action.

[0127] The bag-picking motor 3208 drives the second rotating shaft 3203 to rotate to the initial position, and the second bag-supporting cylinder 3206 is in the retracted state. After the bag-feeding assembly 200 completes the bag-opening action, the bag-picking motor 3208 drives the second rotating shaft 3203 to rotate around the second bearing seat 3202, which drives the end support rods of the second left support rod 3205 and the second right support rod 3207 to insert into the open packaging bag.

[0128] The second bag-supporting cylinder 3206 extends, and the second left support rod 3205 and the second right support rod 3207 open and straighten the opening of the packaging bag. At this time, the bag feeding assembly 200 shuts off the negative pressure. After the equipment sends a signal that the bag can be loaded, the bag picking motor 3208 drives the second rotating shaft 3203 to rotate 90°, putting the packaging bag into the bag clamping assembly 600.

[0129] The second bag-supporting cylinder 3206 retracts its long-stroke portion, while the bag-picking motor 3208 drives the second rotating shaft 3203 to continue rotating, causing the second left support rod 3205 and the second right support rod 3207 to lift upwards and disengage from the packaging bag opening. Then, the second bag-supporting cylinder 3206 extends fully in both its long and short strokes, and the bag-picking motor 3208 drives the second rotating shaft 3203 to rotate in the opposite direction, returning it to its initial position. The second bag-supporting cylinder 3206 then retracts fully in both its long and short strokes, repeating the bag-picking process.

[0130] like Figure 11 As shown, the frame assembly 400 in this invention may preferably include, but is not limited to, the following: a frame body 401, a dust removal system 402, an air control box 403, a cable tray 404, and an outer protective layer 405. The dust removal system 402 is installed on the top of the frame body 401, the air control box 403 is located on one side of the frame body 401, the cable tray 404 is arranged along the edge of the frame body 401, and the outer protective layer 405 is located on the front of the frame body 401.

[0131] Here, the framework component 400 provides a basic platform for the modular construction of the platform-based fully automatic bag-loading machine of the present invention.

[0132] like Figure 12 As shown, the lifting assembly 500 in this invention may preferably include, but is not limited to: a bag clamping connecting rod 501, a lifting cylinder 502, a lifting connecting rod 503, a lifting frame 504, a swing shaft 505, a lifting guide wheel 506, a transition material tube 507, and a guide rod 508.

[0133] The guide rod 508 is fixed inside both sides of the lifting frame 504. The lifting guide wheel 506 is fixed on the transition tube 507 and moves up and down along the guide rod 508 (i.e., lifting action). The transition tube 507 is located inside the lifting frame 504. The swing shaft 505 is installed inside one side of the lifting frame 504. One end rotates and swings around a fixed point, and the other end is rotatably connected to the transition tube 507 (for example, the lug of the swing shaft 505 is hinged to the transition tube 507).

[0134] The bag clamping connecting rod 501 is fixed below the transition material tube 507 and is used to install the bag clamping assembly 600. One end of the lifting connecting rod 503 is rotatably connected to the swing shaft 505 (e.g., hinged), and the other end is connected to the piston rod of the lifting cylinder 502 (e.g., hinged). The tail end of the lifting cylinder 502 is connected to the lifting frame 504 (e.g., mounted on the side of the lifting frame 504).

[0135] Preferably, the lifting assembly 500 may further include a counterweight 509, which is mounted on the other end of the swing shaft 505.

[0136] The lifting assembly 500 may also preferably include a flexible connection 510, which is installed at the top of the transition tube 507.

[0137] When the bag-picking assembly 300 loads a bag, the lifting cylinder 502 retracts, bringing the bag-clamping assembly 600 to its initial position. After material filling is complete, the lifting cylinder 502 extends, and the lifting linkage 503 drives the swing shaft 505 to rotate. The transition material pipe 507 descends, causing the bag-clamping assembly 600 to descend along with the packaging bag, and the packaging bag is smoothly placed on the conveyor 900 under the scale. After the bag-holding assembly 800 holds the bag, the lifting cylinder 502 retracts, driving the bag-clamping assembly 600 back to its initial state, and the bag-loading operation is repeated.

[0138] like Figure 13 As shown, the bag clamping assembly 600 in this invention may preferably include, but is not limited to: a bag clamping frame 601, a bag clamping alligator plate 602, an alligator plate cylinder 603, an insert cylinder 604, a dust removal hood 605, an insert assembly 606, a lever cylinder 607, a lever assembly 608, a bag pressing plate 609, a bag pressing cylinder 610, and a bag pressing detection device 611.

[0139] The bag clamping frame 601 is hoisted and fixed to the bag clamping connecting rod 501 of the lifting assembly 500. The bag clamping alligator plate 602 includes two sets of alligator plates, left and right, which are rotatably connected to the bag clamping frame 601 via a rotating shaft. The tail end of the alligator plate cylinder 603 is connected (e.g., hinged) to the bag clamping frame 601, and the piston rod end is rotatably connected (e.g., hinged) to the bag clamping alligator plate 602. The alligator plate cylinder 603 drives the bag clamping alligator plate 602 to rotate, controlling the opening and closing of the bag clamping alligator plate 602.

[0140] The bag-pressing plate 609 is rotatably (e.g., via a pivot) mounted on the bag-clamping plate 602. The tail end of the bag-pressing cylinder 610 is mounted on the bag-clamping plate 602, and the piston rod end is connected to the bag-pressing plate 609. The dust collector hood 605 is fixed above the bag-clamping frame 601. The insert assembly 606 and the lever assembly 608 are mounted on the left and right sides of the bag-clamping frame 601. The insert cylinder 604 is mounted on the rear side of the bag-clamping frame 601, driving the insert assembly 606 to move left and right. The lever cylinder 607 is connected to the lever assembly 608, driving the lever assembly 608 to open and close.

[0141] Preferably, the bag clamping assembly 600 may further include a dust removal pipe 612, which is installed on the rear side of the bag clamping frame 601.

[0142] After the bag-picking assembly 300 inserts the packaging bag, the bag-pressing cylinder 610 drives the bag-pressing plate 609 to press the packaging bag tightly, and the bag-pressing detection device 611 triggers a signal to determine whether the bag insertion is successful. The alligator plate cylinder 603 drives the bag-clamping alligator plate 602 to open, and at the same time, the lever cylinder 607 drives the lever assembly 608 to open and support the opening of the packaging bag, and the filling of materials into the packaging bag begins.

[0143] After filling is complete, the lifting assembly 500 lowers the bag clamping assembly 600, while the inserting cylinder 604 drives the inserting assembly 606 to insert, the lever cylinder 607 drives the lever assembly 608 to close, and the alligator plate cylinder 603 drives the bag clamping alligator plate 602 to close. Once the lifting assembly 500 has reached its lowest point and the packaging bag has fallen onto the conveyor 900 below the scale, the bag holding assembly 800 clamps the bag, and the bag pressing cylinder 610 drives the bag pressing plate 609 to release. The inserting cylinder 604 then drives the inserting assembly 606 to retract, and the lifting assembly 500 raises the bag clamping assembly 600, completely detaching the packaging bag.

[0144] like Figure 14 As shown, the guide exhaust assembly 700 in this invention can preferably be a first guide exhaust assembly 7100, which includes two sets of first guide belt assemblies 7101, a first guide belt opening and closing cylinder 7102, an exhaust cylinder 7103, a cross-bag pressing cylinder 7104, an exhaust bracket 7105, a guide belt drive motor 7106, and a first bracket 7107.

[0145] The first guide belt assembly 7101 is fixed on the first bracket 7107 by a rotating shaft. The first guide belt opening and closing cylinder 7102 is connected to the first guide belt assembly 7101 and is used to drive the first guide belt assembly 7101 to open and close (i.e. control the opening and closing of the first guide belt assembly 7101). The guide belt drive motor 7196 is installed above the first bracket 7107 and is used to drive the first guide belt assembly 7101 to rotate. The two sets of first guide belt assemblies 7101 are driven to rotate through the gearbox and synchronous belt rotation mechanism.

[0146] The exhaust bracket 7105 is mounted on the first bracket 7107 and located outside the first guide belt assembly 7101. The cross-pressure bag cylinder 7104 is mounted on the first bracket 7107 and is used to drive the exhaust bracket 7105 to open and close.

[0147] For example, two rows of exhaust brackets 7105 are arranged in an "X" shape and located outside the first guide belt assembly 7101. They are also fixed to the first bracket 7109 by a mounting shaft. The cross-pressure bag cylinder 7104 drives the exhaust brackets 7105 to open and close.

[0148] Preferably, the guide exhaust assembly 7100 may further include an exhaust roller 7108 and an exhaust clamp 7109, with the exhaust roller 7108 and exhaust clamp 7109 mounted on the exhaust bracket 7105, and the exhaust roller 7108 moving up and down under the action of the exhaust cylinder 7103.

[0149] When the bag-holding assembly 800 clamps the filled packaging bag under the guide and venting assembly 7100, the first guide belt opening and closing cylinder 7102 drives the first guide belt assembly 7101 to clamp the opening of the packaging bag. The bag-holding assembly 800 releases the clamp and moves back under the bag-clamping assembly 600. The cross-bag pressing cylinder 7104 drives the venting bracket 7105 to rotate, and the venting clamp 7109 clamps the opening of the packaging bag under the first guide belt opening and closing cylinder 7102. The first guide belt opening and closing cylinder 7102 then drives the first guide belt assembly 7101 to open.

[0150] The exhaust cylinder 7103 drives the exhaust roller 7108 to press down, squeezing out the residual air at the opening of the packaging bag. The first guide belt opening and closing cylinder 7102 drives the first guide belt assembly 7101 to clamp the opening of the packaging bag. The cross-bag pressing cylinder 7104 drives the exhaust bracket 7105 to open. The guide belt drive motor 7106 rotates, cooperating with the conveyor under the scale 900 to send the packaging bag to the next work station.

[0151] like Figure 15 As shown, the guide exhaust assembly 700 in this invention can preferably be a second guide exhaust assembly 7200, which includes two sets of second guide belt assemblies 7201, a second guide belt opening and closing cylinder 7202, an exhaust rod 7203, a second guide belt drive motor 7204, and a second bracket 7205.

[0152] The second guide belt assembly 7201 is fixed to the second bracket 7205 via a rotating shaft. The second guide belt opening / closing cylinder 7202 is connected to the second guide belt assembly 7201 and is used to drive the second guide belt assembly 7201 to open and close (i.e., control the opening and closing of the second guide belt assembly 7201). The second guide belt drive motor 7204 is mounted above the second bracket 7205 and is used to drive the second guide belt assembly 7201 to rotate. The exhaust rod 7203 is fixed to the tail end of the second bracket 7205. The second guide belt drive motor 7204 drives the rotation of the two sets of second guide belt assemblies 7201 through a gearbox and a synchronous belt rotation mechanism.

[0153] In addition, the exhaust rod 7203 is fixed to the tail end of the second bracket 7205.

[0154] The bag holding assembly 800 clamps the filled packaging bag under the guide and exhaust assembly 7200. The second guide belt opening and closing cylinder 7202 drives the second guide belt assembly 7201 to clamp the opening of the packaging bag. The second guide belt drive motor 7204 drives the second guide belt assembly 7201 to rotate, cooperating with the conveyor under the scale 900 to transport it to the next station. During the transport process, the exhaust rod 7203 squeezes and discharges the gas from the opening of the packaging bag.

[0155] like Figure 16 As shown, the bag-holding assembly 800 in this invention can preferably be a first bag-holding assembly 8100, including a first frame 8101, a transverse cylinder 8102, a first bag-holding plate 8103, a first bag-holding frame 8104, a first bag-holding cylinder 8105, a first bag opening clamping plate 8106, a first clamping cylinder 8107, and a first guide shaft 8108.

[0156] The first bag-holding frame 8104 is mounted on the first guide shaft 8108 on the lower side of the first frame 8101 and can move back and forth along the first guide shaft 8108. The piston rod end of the transverse cylinder 8102 is rotatably connected (e.g., hinged) to the first bag-holding frame 8104, and the cylinder body of the transverse cylinder 8102 is fixed on the first frame 8101.

[0157] The first bag-holding cylinder 8105 and the first clamping cylinder 8107 are fixed on the first bag-holding frame 8104. The piston rod end of the first bag-holding cylinder 8105 is connected to the first bag-holding plate 8103, and the piston rod end of the first clamping cylinder 8107 is connected to the first bag-mouth clamping plate 8106.

[0158] After the lifting assembly 500 lowers and places the packaging bag onto the conveying device 900 under the scale, the first bag-holding cylinder 8105 and the first clamping cylinder 8107 simultaneously drive the first bag-holding plate 8103 and the first bag-mouth clamping plate 8106 to clamp the packaging bag. After the lifting assembly 500 drives the clamping assembly 600 to rise and detach from the packaging bag, the lateral movement cylinder 8102 extends and drives the first bag-holding frame 8104 to move the packaging bag laterally to below the guide exhaust assembly 700.

[0159] like Figure 17 As shown, the bag-holding assembly 800 in this invention can preferably be a second bag-holding assembly 8200, including a transverse motor 8201, a transverse crank 8202, a second frame 8203, a second guide shaft 8204, a second bag-holding frame 8205, a second bag-holding cylinder 8206, a second bag-holding plate 8207, a second clamping cylinder 8208, and a second bag opening clamping plate 8209.

[0160] The second bag-holding frame 8205 is mounted on the second guide shaft 8204 on the lower side of the second frame 8203 and can move back and forth along the second guide shaft 8204. The transverse motor 8201 is fixed to the tail end of the second frame 8203 and is connected to the second bag-holding frame 8205 through the transverse crank 8202.

[0161] The second bag-holding cylinder 8206 and the second clamping cylinder 8208 are fixed on the second bag-holding frame 8205. The piston rod end of the second bag-holding cylinder 8206 is connected to the second bag-holding plate 8207, and the piston rod end of the second clamping cylinder 8208 is connected to the second bag opening clamping plate 8209.

[0162] After the lifting assembly 500 lowers and places the packaging bag onto the conveyor 900 under the scale, the second bag-holding cylinder 8206 and the second clamping cylinder 8208 simultaneously drive the second bag-holding plate 8207 and the second bag-mouth clamping plate 8209 to clamp the packaging bag. After the lifting assembly 500 drives the bag-clamping assembly 600 to rise and detach from the packaging bag, the transverse motor 8201 drives the transverse crank 8202 to rotate, causing the second bag-holding frame 8205 to quickly move laterally along with the packaging bag to below the guide exhaust assembly 700.

[0163] In summary, this invention is a platform-based modular fully automatic bag-loading machine. By configuring multiple series of modules on a single basic construction platform, it achieves a series configuration of product capacity and cost from low to high. The same space and docking dimensions can meet the equipment installation requirements of different production capacities, reducing the difficulty of initial plant planning for users. When users need to adjust or increase production capacity later, they can simply replace the corresponding modules.

[0164] The bag-picking method allows the equipment to be compatible with various types of packaging materials such as PP, PE, and kraft paper bags, with a bag-loading success rate of over 99%. The enclosed packaging area enhances product safety and protection, and combined with multiple dust removal systems, it solves the dust problem during the material filling process.
