Description

Technical Field

[0001] The present invention relates to the field of new packaging machinery, in particular to a fully automatic bagging and packaging system. Background Art

[0002] In the industrial packaging of powdered, granular, or small-block materials (such as fertilizers, feed, grain, and chemical raw materials), automated bagging systems have become critical equipment for improving efficiency and reducing labor costs. Traditional manual bagging, opening, and bagging methods are not only inefficient and labor-intensive, but also pose high rates of operational errors and a high risk of dust pollution in the workplace. While some automated equipment on the market attempts to address these issues, practical operation still faces numerous challenges. For example, existing systems lack efficiency and stability when it comes to reliably and damage-free separation of stacked packaging bags and flattening them for transportation. In the critical process of opening the bag opening, the mechanism design is complex or the reliability is low, resulting in the bag opening being unable to open effectively or the opening effect being unstable, affecting the success rate of subsequent bagging. When the opened bag opening is accurately and firmly placed on the outlet of the feed hopper, bagging often fails or material leaks due to inaccurate alignment or unstable clamping. Especially during the material injection process and the initial stages of subsequent transportation, the packaging bags are prone to tilting, offsetting, or even tipping over due to changes in gravity and conveying vibrations, resulting in material spillage and bag breakage, seriously affecting the continuity of the production line and the packaging quality. Therefore, there is an urgent need to develop a highly integrated, stable, reliable, and fully automated bagging packaging system to completely resolve the above-mentioned pain points and achieve unmanned, efficient, and high-quality packaging operations. Summary of the Invention

[0003] In view of the shortcomings of the prior art, the present invention provides a fully automatic bagging and packaging system with high efficiency and stable operation.

[0004] The present invention is implemented through the following technical solutions, providing a fully automatic bagging and packaging system, comprising: The loading mechanism includes a circulating conveyor belt. The packaging bags are stacked and placed on a placement plate on the inner circle of the conveyor belt. A loading port is opened on the conveyor belt. The loading suction cup cylinder drives the loading pneumatic suction cup to absorb the top packaging bag from the loading port and lift it to the top of the conveyor belt. The packaging bags are flattened on the conveyor belt as the conveyor belt moves; The opening transfer mechanism is used to open the bag opening on the conveyor belt and put the bag opening on the discharge port of the feed silo; The feeding silo has an openable and closable discharge port at the lower end. When the discharge port is opened, the material is poured into the packaging bag. The bag pulling and supporting mechanism is used to clamp the bag opening of the bag to pull and support the bag when the bag containing the material is transported on the main conveyor belt.

[0005] As an optimization, the feeding mechanism includes a feeding frame, a placement plate and two side-by-side circulating chains, a conveyor belt is connected between the two circulating chains, and the conveyor belt surrounds the placement plate. It also includes a feeding suction cup frame and a feeding suction cup cylinder that drives the feeding suction cup frame to rise and fall. The feeding suction cup frame is equipped with multiple feeding pneumatic suction cups, and the conveyor belt is provided with a feeding port for the feeding suction cup frame and the packaging bag to pass through. In this solution, the feeding suction cup cylinder extends to drive the feeding suction cup frame to pass through the feeding port and descend to the top of one end of the packaging bag, and the feeding pneumatic suction cup absorbs the end of the topmost packaging bag, and then the feeding suction cup cylinder contracts to lift one end of the packaging bag to the top of the feeding port. The circulating chain moves, causing the upper layer of the conveyor belt to move to the left, and the packaging bag is flatly laid on the conveyor belt. At the same time, the feeding pneumatic suction cup is released, thereby realizing the flat loading of a single packaging bag on the conveyor belt.

[0006] As an optimization, the loading mechanism further includes a loading push rod for pushing the packaging bags placed on the flat plate horizontally to below the loading port. The loading push rod in this solution can push the packaging bags placed on the flat plate horizontally to below the loading port, thereby eliminating the need for workers to place the stacked packaging bags below the loading port, thereby facilitating the placement of packaging bags.

[0007] As an optimization, the opening transfer mechanism includes a support platform located at the end of the conveyor belt, and upper and lower pneumatic suction cups located on the upper and lower sides of the support platform, respectively. The support platform has a through hole for the lower pneumatic suction cup to pass through, and also includes an upper suction cup lifting mechanism that drives the upper pneumatic suction cup to move up and down, and a lower suction cup lifting mechanism that drives the lower pneumatic suction cup to move up and down. It also includes a rotating shaft located on the support platform, a transfer motor that drives the rotating shaft to rotate, two opening arms hinged on the rotating shaft, and an opening cylinder that drives the two opening arms to open and close. In this solution, the upper and lower pneumatic suction cups are respectively attached to the upper and lower sides of the bag opening, and the bag opening is opened by the reverse movement of the upper and lower cylinders. The transfer motor drives the rotating shaft to rotate, causing the ends of the opening arms to insert into the bag opening. The opening cylinder drives the two opening arms to swing in opposite directions, and the two support plates are respectively attached to the two ends of the opening to open the bag opening. The transfer motor then drives the rotating shaft to reset, causing the opening arms to swing upward, thereby adjusting the packaging bag to a state where the bag opening is facing upward.

[0008] As an optimization, the opening transfer mechanism also includes upper pressing wheels and support wheels located on the upper and lower sides of the packaging bag, an upper pressing wheel drive mechanism that drives the upper pressing wheels to press against the support wheels, and a support wheel motor that drives the support wheels to rotate. In this solution, as the packaging bag is conveyed forward, the upper pressing wheels press the packaging bag against the lower support wheels, and the support wheel motor drives the support wheels to rotate, causing wrinkles at the bag opening, facilitating opening of the bag.

[0009] As an optimization, a baffle and a baffle cylinder for driving the baffle to rise and fall are installed in front of the support platform. When the packaging bag is transported forward on the support platform, the baffle plays a limiting role on the front end of the packaging bag.

[0010] As an optimization, the feed silo includes a silo body with a discharge port at the lower end, and blanking plates are hinged on the front and rear sides of the lower end of the silo body. The lower ends of the two blanking plates are fitted together to seal the discharge port, and the lower ends of the two blanking plates are separated to open the discharge port. A limit stopper fixed to the silo body is provided on the side of the two blanking plates away from each other, and an opening cylinder for driving the blanking plates to swing is installed on the silo body. In this solution, when in use, the bag opening of the packaging bag is put on the lower ends of the two closed blanking plates, and the opening cylinder drives the two blanking plates to open, and presses the two sides of the bag opening of the packaging bag against the two limit stoppers respectively to fix the position of the bag opening of the packaging bag. After the blanking plates are opened, the material in the silo body falls into the packaging bag. After bagging is completed, the two blanking plates are closed to seal the discharge port, and the packaging bag containing the material falls.

[0011] As an optimization, the feed silo also includes a bag-supporting mechanism comprising a vertically elevating lift plate, two bag-supporting sliding seats slidably connected to the lift plate, and a bag-supporting drive mechanism that drives the two bag-supporting sliding seats to slide in opposite directions. The bag-supporting sliding seats are fixedly connected to bag-supporting arms, which are fixedly connected to vertical bag-supporting rods. The two bag-supporting rods are located on the left and right sides of the silo body. In this solution, the two bag-supporting rods are inserted into the bag opening when the bag is inserted. As the two bag-supporting rods move outward, they open the two ends of the bag opening, straightening the bag opening of the bag containing the material, facilitating subsequent conveying.

[0012] As an optimization, the traction and supporting bag mechanism includes a first guiding assembly and a second guiding assembly, the first guiding assembly includes a guiding frame, a first movable plate sliding on the guiding frame, and a first driving mechanism that drives the first movable plate to move back and forth, the first guiding assembly also includes two first clamping arms hinged on the first movable plate and a first clamping cylinder that drives the two first clamping arms to swing in opposite directions; the second guiding assembly includes two second clamping arms hinged on the guiding frame and a second clamping cylinder that drives the two second clamping arms to swing in opposite directions, and the lower end of the second clamping arm is fixedly connected to a belt conveyor assembly. In this solution, the packaging bags that have been bagged at the feed hopper fall onto the main conveyor belt, and the first guiding assembly retreats to the feed hopper, clamps the bag opening of the packaging bag through two first clamping arms, and then the first guiding assembly moves forward with the main conveyor belt to guide the packaging bags on the main conveyor belt. When the bag opening position of the packaging bag moves to between the belt conveyor assemblies at the lower end of the second clamping arm in the second guiding assembly, the bag opening of the packaging bag is clamped by the two belt conveyor assemblies, the clamping slats are released, and then the packaging bags are guided during the conveying process by moving the guiding conveyor belt in the belt conveyor assembly.

[0013] As an optimization, the lower end of the first clamping arm is fixedly connected with a clamping strip, and the two clamping strips are arranged in parallel. In this solution, the bag opening is clamped by the clamping strips.

[0014] The beneficial effects of the present invention are as follows: the fully automatic bagging and packaging system of the present invention realizes high automation of the entire process from loading, opening, bagging, filling to transportation of packaging bags through the integration of innovative loading mechanisms, opening transfer mechanisms, feed silos and traction and bag-supporting mechanisms, which significantly improves packaging efficiency and stability. Its loading mechanism can efficiently and reliably separate the stacked packaging bags one by one and convey them flatly, laying the foundation for subsequent processes; the opening transfer mechanism is cleverly designed, which can stably and accurately open the bag opening and firmly cover the outlet of the feed silo, greatly improving the success rate of bagging and sealing; the controllable outlet of the feed silo ensures the accurate injection of materials. What is particularly critical is that the traction and bag-supporting mechanism continuously clamps and guides the bag opening of the packaging bag after the material is injected and in the initial stage of transportation on the main conveyor belt, effectively preventing the bag from tilting, deflecting, tipping over and material leakage caused by gravity changes and conveying vibrations, and ensuring the stability of the conveying process and the integrity of the packaging. The entire system is closely connected and operates collaboratively smoothly, which not only greatly reduces dependence on manual labor, significantly reduces labor intensity and operational risks, and improves production safety, but also greatly improves packaging speed, success rate and product quality consistency, reduces packaging bag breakage rate and material waste, and has significant overall economic benefits, providing an efficient and reliable solution for modern large-scale industrial packaging.

DETAILED DESCRIPTION

[0016] In order to clearly illustrate the technical features of this solution, this solution is described below through specific implementation methods.

[0017] like Figures 1 to 26As shown, a fully automatic bagging and packaging system of the present invention comprises a loading mechanism 1, a supporting mouth transfer mechanism 2, a feed silo 3 and a pulling and supporting bag mechanism 4. In this embodiment, the loading mechanism 1, the supporting mouth transfer mechanism 2, the feed silo 3 and the pulling and supporting bag mechanism 4 are connected as a whole through a main frame 6.

[0018] The packaging bags 5 are stacked and placed on the placement flat plate 113 , and the loading mechanism 1 is used to lay the top packaging bag 5 flat on the conveyor belt 13 .

[0019] The opening transfer mechanism 2 is used to open the bag opening of the packaging bag 5 on the conveyor belt 13 and put the bag opening on the discharge port of the feed silo 3.

[0020] The lower end of the feed silo 3 is provided with an openable and closable discharge port, and the material is injected into the packaging bag 5 when the lower discharge port is opened.

[0021] The packaging bag containing the material is transported on the main conveyor belt. The bag pulling and supporting mechanism 4 is used to clamp the bag opening of the packaging bag to achieve bag pulling and supporting when the packaging bag 5 is transported on the main conveyor belt.

[0022] like Figures 5 to 9 As shown, the loading mechanism of the present invention includes a loading frame 11, a placing plate 113 and two side-by-side circulating chains 12. The loading frame 11 is the supporting skeleton of the entire loading mechanism, which is generally composed of profile welding or bolt connection. The placing plate 113 is a horizontal metal plate. Workers place multiple stacked packaging bags 5 on the placing plate 113. Loading side baffles 117 are installed on both sides of the placing plate 113.

[0023] Two circulating chains 12 are arranged side by side, as Figure 7 As shown, the endless chain passes around the driving sprocket 14, the first sprocket 110, the second sprocket 111 and the third sprocket 112 arranged in a quadrilateral, and also includes a conveyor belt motor 19 that drives the driving sprocket 14 to rotate. Thus, the endless chain 12 is driven to move by the rotation of the driving sprocket 14. In this embodiment, the two driving sprockets 14 are connected by a sprocket shaft 15. The conveyor belt motor 19 drives the sprocket shaft 15 to rotate through the power transmission belt 17, as shown in FIG. Figure 7 As shown, a driving pulley 18 is fixedly connected to the rotating shaft of the conveyor belt motor 19 , a passive pulley 16 is fixedly connected to the sprocket rotating shaft 15 , and a power transmission belt 17 connects the passive pulley 16 and the driving pulley 18 .

[0024] The first sprocket 110 and the second sprocket 111 are at the same height and are located above, and the driving sprocket 14 and the third sprocket 112 are at the same height and are located below, so that the endless chain between the first sprocket 110 and the second sprocket 111 moves horizontally.

[0025] A conveyor belt 13 is connected between the two endless chains 12. In this embodiment, the conveyor belt 13 is a stainless steel mesh belt, and the endless chain 12 is a 10A chain. The conveyor belt 13 surrounds the placement plate 113. In other words, one end of the placement plate 113 is inserted between the upper and lower conveyor belts 13, allowing multiple stacked packaging bags to move under the upper conveyor belt 13. In this embodiment, the other end of the placement plate 113 extends outside the conveyor belt 13, allowing workers to place stacked packaging bags at this end for easy placement.

[0026] The system also includes loading push rods 114 that push the bags horizontally from the placement plate 113 to below the loading port. Two loading push rods 114 are provided, and the placement plate 113 has slots for these push rods. The distance between the two loading push rods 114 is less than the length of the bags, allowing them to push the bags directly below the upper conveyor belt 13.

[0027] like Figure 6 As shown, the loading push rod 114 is vertically fixed on the push rod moving frame 115, and the push rod moving frame 115 is arranged below the placement plate 113. Two slide rails are fixed to the lower end surface of the placement plate 113. A slider is installed on the push rod moving frame 115, thereby realizing the sliding guide of the push rod moving frame 115. A loading cylinder 116 is installed below the placement plate 113 to drive the push rod moving frame 115 to move horizontally.

[0028] It also includes a loading suction cup frame 119 and a loading suction cup cylinder 118 that drives the loading suction cup frame 119 to rise and fall. The loading suction cup cylinder 118 extends and retracts vertically downward. The loading suction cup frame 119 is equipped with multiple loading pneumatic suction cups 120. In this embodiment, two loading pneumatic suction cups 120 are provided.

[0029] like Figure 6 As shown, the conveyor belt 13 is provided with a loading port for accommodating a loading suction cup rack 119 and a packaging bag to pass through, so that the loading suction cup rack 119 and the loading pneumatic suction cup 120 can pass through the loading port to suck one end of the packaging bag to above the upper end surface of the conveyor belt 13. The conveyor belt 13 in this embodiment is segmented, specifically two sections, and a loading port is formed between the two adjacent sections. Therefore, there are two loading ports in total. After one end of the packaging bag is lifted to above the upper end surface of the conveyor belt 13, it moves through the conveyor belt 13, and the edge of the conveyor belt pushes the packaging bag so that the packaging bag is flat on the upper end surface of the conveyor belt.

[0030] When the feeding mechanism is working, multiple packaging bags are stacked and placed on the placement plate 113. The packaging bags are pushed to the bottom of the feeding port by the feeding push rod 114. The feeding suction cup cylinder 118 extends downward, driving the feeding suction cup frame 119 to pass through the feeding port and descend to the top of one end of the packaging bag. The end of the top packaging bag is sucked by the feeding pneumatic suction cup 120 ( Figure 7 Then the feeding suction cup cylinder 118 contracts to lift one end of the packaging bag to the top of the feeding port ( Figure 8 As shown in the state), the circulating chain 12 moves, causing the upper layer of the conveyor belt 13 to move to the left, and the packaging bags are laid flat on the conveyor belt 13 ( Figure 9 As shown in the state), the pneumatic suction cup 120 for loading is released at the same time, thereby achieving the flat loading of a single packaging bag on the conveyor belt 13.

[0031] like Figures 10-13 As shown, the opening transfer mechanism 2 of the present invention includes a support platform 27 and an upper pneumatic suction cup 210 and a lower pneumatic suction cup 213 respectively located on the upper and lower sides of the support platform 27. The support platform 27 is a horizontal flat plate structure. The support platform 27 is fixedly connected to the main frame 6 and is arranged at the end of the conveyor belt 13 of the feeding mechanism. The height of the support platform 27 is flush with the upper end surface of the conveyor belt. Therefore, when a single packaging bag is conveyed forward, the bag opening position at the front end can be moved to the support platform 27.

[0032] The packaging bag further includes upper pressing wheels 218 and support wheels 219 located on the upper and lower sides of the packaging bag. There are two upper pressing wheels 218 and two support wheels 219, each of which is provided. The support wheels 219 are arranged below the support platform 27, and the upper ends of the support wheels 219 are slightly higher than the upper end surface of the support platform 27. A rectangular opening is opened on the support platform 27 to facilitate the exposure of the upper ends of the support wheels 219. A support wheel motor is installed below the support platform 27 to drive the support wheels 219 to rotate.

[0033] It also includes an upper pressing wheel driving mechanism that drives the upper pressing wheel 218 to press against the supporting wheel 219. Figure 12 As shown, the upper pressing wheel 218 is installed on a four-bar linkage 220. The four-bar linkage is a quadrilateral structure formed by hinged ends of four links in sequence. The upper pressing wheel 218 is axially connected to a link below, and the upper link is driven up and down by the upper pressing wheel cylinder 221, thereby realizing the up and down movement of the upper pressing wheel 218. The upper end of the upper pressing wheel cylinder 221 is hinged to the fixed four-bar mounting frame 222, and the lower end is hinged to the link. The upper pressing wheel 218 is driven downward by the extension of the upper pressing wheel cylinder 221. After the upper pressing wheel 218 is pressed against the supporting wheel 219, the rotation of the supporting wheel 219 drives the packaging bag to move forward to prevent the packaging bag from getting stuck on the supporting platform 27.

[0034] A baffle 216 and a baffle cylinder 217 for driving the baffle 216 to rise and fall are installed in front of the support platform 27. The baffle cylinder 217 is fixed with the telescopic shaft facing upward. The baffle 216 is vertically fixed to the telescopic shaft of the baffle cylinder 217. When the packaging bag is conveyed forward, the baffle 216 is used to limit the packaging bag.

[0035] The support platform 27 is provided with a through hole for accommodating the lower pneumatic suction cup 213 to pass through, so that the lower pneumatic suction cup 213 can be in contact with the lower end surface of the bag opening of the packaging bag to absorb the packaging bag at the lower layer.

[0036] It also includes an upper suction cup lifting mechanism for driving the upper pneumatic suction cup 210 to move up and down, and a lower suction cup lifting mechanism for driving the lower pneumatic suction cup 213 to move up and down.

[0037] The upper suction cup lifting mechanism includes an upper cylinder 28 and an upper suction cup mounting plate 29 fixedly connected to the telescopic shaft of the upper cylinder 28. The upper cylinder 28 is fixed with the telescopic shaft facing downward. Two upper pneumatic suction cups 210 are installed on the upper suction cup mounting plate 29. The upper suction cup mounting plate 29 is a hollow structure and is connected to both upper pneumatic suction cups 210. The pneumatic pipeline is connected to the interior of the upper suction cup mounting plate 29, so that the adsorption operation of the two upper pneumatic suction cups 210 can be realized at the same time.

[0038] The lower suction cup lifting mechanism includes a lower cylinder 211 and a lower suction cup mounting plate 212 fixed to the telescopic shaft of the lower cylinder 211. The lower cylinder 211 is located below the support platform 27 and is fixed with the telescopic shaft facing upward. Two lower pneumatic suction cups 213 are mounted on the lower suction cup mounting plate 212. The lower suction cup mounting plate 212 is a hollow structure and is connected to both lower pneumatic suction cups 213. The pneumatic pipeline is connected to the interior of the lower suction cup mounting plate 212, so that the suction operation of both lower pneumatic suction cups 213 can be achieved simultaneously. When the packaging bag is moved onto the support platform 27, the lower cylinder 211 drives the lower pneumatic suction cups 213 to a lower position, thereby not affecting the normal movement of the packaging bag.

[0039] It also includes a rotating shaft 21 located on the support platform 27 and a transfer motor 215 that drives the rotating shaft 21 to rotate. The rotating shaft 21 is rotatably connected to the rotating shaft bearing seat 26. The rotating shaft bearing seat 26 is installed on the main frame 6. The transfer motor is fixed to the transfer motor reducer 214. The transfer motor drives the rotating shaft 21 to rotate after being decelerated by the transfer motor reducer 214. The rotating shaft 21 is horizontally arranged and the length direction is perpendicular to the direction of the bag opening.

[0040] The device also includes two opening arms 22 hingedly connected to the rotating shaft 21 and an opening cylinder 24 that drives the opening arms 22 to open and close. The two opening arms 22 are arranged along the length of the rotating shaft 21, and the hinge axis between the opening arms 22 and the rotating shaft 21 is perpendicular to the axis of the rotating shaft 21. The rotation of the rotating shaft 21 can drive the opening arms 22 to swing between a horizontal state and a vertical state.

[0041] The two opening arms 22 can be driven to swing in opposite directions by the opening cylinder 24, thereby realizing the opening and closing operation of the two opening arms 22. The two ends of the opening cylinder 24 are respectively hinged to the two opening arms 22, so that the two opening arms 22 can swing in opposite directions by one opening cylinder 24. In order to realize the synchronous swing of the two opening arms 22, as shown in FIG. Figure 11 As shown, a synchronous link 25 is connected between the two support arms 22, and the two ends of the synchronous link 25 are respectively hinged to the two support arms 22, and the two ends of the synchronous link 25 are respectively located on both sides of the rotating shaft 21, as shown in FIG. Figure 11 As shown, when Figure 11 When the left support arm 22 swings to the right, it drives the synchronous connecting rod 25 to move to the right, thereby driving the upper end position of the right support arm 22 to move to the right, and also drives the main body of the right support arm 22 to swing to the left.

[0042] A support plate 23 is fixedly connected to one end of the opening-opening arm 22, which is close to the support platform 27. In this embodiment, the support plate 23 and the opening-opening arm 22 are integrally formed. The support plate 23 is located on the side of the opening-opening arm 22 close to the bag opening. When the support plate 23 is inserted into the bag opening, the two support plates 23 are parallel or nearly parallel, thereby expanding the bag opening.

[0043] When the opening transfer mechanism 2 is working, the initial state is as follows Figure 12As shown, the packaging bag is transported forward by the conveyor belt of the feeding mechanism. When the front end of the packaging bag covers the support wheel 219, the upper pressure wheel 218 moves downward, pressing the packaging bag against the support wheel 219. The rotation of the support wheel 219 drives the packaging bag forward, and the baffle 216 is now in the raised state. After the packaging bag is in place, the upper pressure wheel 218 returns to its original position, and the upper cylinder 28 drives the upper pneumatic suction cup 210 to descend above the bag opening. The lower cylinder 211 drives the lower pneumatic suction cup 213 to rise below the bag opening. The upper pneumatic suction cup 210 and the lower pneumatic suction cup 213 respectively adhere to the two sides of the bag opening. The upper cylinder 28 and the lower cylinder 211 return to their original position, and the bag opening is opened. The transfer motor drives the rotating shaft 21 to rotate, causing the two opening arms 22 to swing downward, so that the support plates 23 at the ends of the opening arms 22 are inserted into the bag opening. The opening cylinder 24 is extended to drive the two opening arms 22 to swing in the opposite direction, and the two support plates 23 are respectively attached to the two ends of the opening, so that the bag opening is opened and the baffle 216 is lowered. Then the transfer motor drives the rotating shaft 21 to reset, causing the opening arms 22 to swing upward, so that the packaging bag is adjusted to a state where the bag opening is facing upward and is placed on the outlet of the feed hopper 3. At this time, the state is as follows: Figure 13 shown.

[0044] like Figures 14 to 19 As shown, the feed silo 3 of the present invention includes a silo body 31 with a discharge port at the lower end, the silo body 31 contains materials, and a feed port is opened at the upper end of the silo body 31 for easy replenishment of materials.

The two blanking plates 32 are fitted together to form a cone, which is convenient for the bag mouth to be put on.

[0046] The silo body 31 is provided with an opening cylinder 34 for driving the blanking plate 32 to swing. The upper end of the opening cylinder 34 is hinged to the bracket outside the silo body 31, and the lower end of the opening cylinder 34 is hinged to the blanking plate 32, thereby realizing the swing of the blanking plate 32.

[0047] A limit stop rod 33 fixed to the silo body 31 is provided on the side where the two blanking plates 32 are away from each other. The two limit stop rods 33 are arranged in parallel, and the two ends of the limit stop rod 33 are respectively fixed to the side plates 35 on the left and right sides of the silo body 31, thereby achieving fixed connection with the silo body 31 through the side plates 35.

[0048] The two blanking plates 32 move in opposite directions until they are pressed against the limiting stop bar 33 and then stop, so that the packaging bag can be pressed between the blanking plates 32 and the limiting stop bar 33.

[0049] The side plates 35 on the left and right sides of the silo body 31 are provided with tapered portions, and the opening of the packaging bag also wraps around the tapered portions when it is sleeved on the lower ends of the two blanking plates 32 .

[0050] The lower ends of the two blanking plates 32 are separated to open the discharge port. At this time, the two blanking plates 32 open the bag opening and press the edges tightly against the limit bar 33. At this time, the material falls into the packaging bag.

[0051] In order to facilitate the bag opening to be long and flat after bagging, and facilitate the subsequent transportation and packaging operations, the present application also includes a bag-supporting mechanism, which includes a vertically lifting and lowering seat plate 36, two bag-supporting sliding seats 38 slidably connected to the lifting seat plate 36, and a bag-supporting driving mechanism that drives the two bag-supporting sliding seats 38 to slide in opposite directions. The lifting plate 36 is located in front of or behind the silo body 31. It slides vertically on two vertical lifting guide shafts 37, which are fixed to the main frame 6. The bag-supporting mechanism also includes a lifting cylinder 313 that drives the lifting plate 36 vertically upward and downward. The upper end of the lifting cylinder 313 is hinged to the frame, and the lower end is hinged to the lifting plate 36, thereby achieving the lifting operation of the lifting plate 36.

[0052] Four box-type linear bearings are fixed to the bag-supporting sliding seat 38 , and two transverse sliding seat guide shafts 39 are fixed to the lifting seat plate 36 . The four box-type linear bearings slide on the two sliding seat guide shafts 39 respectively, thereby realizing the transverse sliding of the bag-supporting sliding seat 38 .

[0053] The bag-holding drive mechanism includes two bag-holding cylinders 310 installed on the lifting seat plate 36. The two bag-holding cylinders 310 have opposite telescopic directions. The cylinder bodies of the bag-holding cylinders 310 are hinged on the lifting seat plate 36. The telescopic axes of the two bag-holding cylinders 310 are respectively connected to the two bag-holding sliding seats 38, thereby realizing the opposite sliding of the two bag-holding sliding seats 38.

[0054] The bag-supporting sliding seat 38 is fixedly connected to two bag-supporting arms 311. These arms 311 are arranged horizontally and parallel to each other, with their ends extending to the left and right sides of the silo body 31. Vertical bag-supporting rods 312 are fixedly connected to the bag-supporting arms 311, one on each side of the silo body 31. The rods 312 are vertical circular shafts. When the packaging bag is placed on the lower end of the silo body 31, the two rods 312 are positioned close to the silo body 31.

[0055] When the feeding silo 3 is working, the opening transfer mechanism 2 puts the bag mouth of the packaging bag on the lower ends of the two closed blanking plates 32, and the opening cylinder 34 drives the two blanking plates 32 to open, and presses the two sides of the bag mouth of the two packaging bags on the two limit bars 33 respectively to fix the position of the bag mouth of the packaging bag. After the blanking plates 32 are opened, the material in the silo body 31 falls into the packaging bag. At the same time, the lifting seat cylinder 313 drives the lifting seat plate 36 to descend, so that the two bag-holding rods 312 are inserted into the two end positions inside the bag mouth of the packaging bag, and then the two bag-holding sliding seats 38 move in the opposite direction, so that the two bag-holding rods 312 hold the two end positions of the bag mouth open. After the bagging is completed, the two blanking plates 32 are closed to realize the blocking of the discharge port, and the packaging bag containing the material falls to the main conveyor belt.

[0056] like Figures 20 to 26 As shown, the traction and supporting mechanism 4 of the present invention includes a first guiding assembly and a second guiding assembly. The first guiding assembly and the second guiding assembly are both located above the main conveyor belt, and the feed end of the main conveyor belt is located below the silo body 31.

[0057] The guiding direction of the traction and bag-supporting mechanism 4 in this application is parallel to the conveying direction of the main conveyor belt. The packaging bags containing materials are conveyed on the main conveyor belt. The traction and bag-supporting mechanism 4 is used to guide the packaging bags during the conveying process, so that the packaging bags remain upright and avoid deviation or tipping.

[0058] like Figure 22-23 As shown, the first guiding assembly includes a guiding frame 41, a first movable plate 42 slidingly connected to the guiding frame 41, and a first driving mechanism for driving the first movable plate 42 to move forward and backward. The guiding frame 41 is located directly above the main conveyor belt and is a long strip structure extending forward and backward, and is fixed by the main frame 6.

[0059] In this embodiment, the first movable plate 42 extends horizontally through the guiding frame 41, with both left and right ends extending beyond the guiding frame 41. To guide the forward and backward movement of the first movable plate 42, fixed movable plate rails 43 are provided on either side of the guiding frame 41. These rails are fixed to the frame, which represents the entire packaging production line. The upper end surfaces of the left and right ends of the first movable plate 42 are slidably connected to the movable plate rails 43 via sliders.

[0060] The first driving mechanism includes a main transmission pulley 48 and a passive transmission pulley 49 arranged front and back and axially connected to the guiding frame 41. A first movable motor 47 is fixed to the end of the guiding frame 41. The rotating shaft of the first movable motor 47 is connected to the main transmission pulley 48, thereby driving the main transmission pulley 48 to rotate. The first driving mechanism also includes a transmission belt 410 that passes around the main transmission pulley 48 and the passive transmission pulley 49. The first movable plate 42 is connected to the transmission belt 410, and the transmission belt 410 is driven to move back and forth through the main transmission pulley 48, thereby driving the first movable plate 42 to move back and forth.

[0061] The first guiding assembly also includes two first clamping arms 44 hinged on the first movable plate 42 and a first clamping cylinder 45 that drives the two first clamping arms 44 to swing in opposite directions; the two first clamping arms 44 are symmetrically arranged, the upper ends of the first clamping arms 44 are hinged to the left and right ends of the first movable plate 42, and the hinge axes of the two first clamping arms 44 are arranged in parallel, so that the two first clamping arms 44 can swing relative to each other, and the lower ends of the first clamping arms 44 are fixedly connected to the clamping strips 46, and the two clamping strips 46 are arranged in parallel, and the bag opening of the packaging bag is clamped by the two clamping strips 46.

[0062] The end of the first movable plate 42 is fixedly connected to a connecting seat. One end of the first clamping cylinder 45 is hinged to the connecting seat, and the other end is hinged to the first clamping arm 44, so that the first clamping arm 44 can swing by the extension and contraction of the first clamping cylinder 45.

[0063] like Figures 24-26 As shown, the second guiding assembly includes two second clamping arms 411 hinged on the guiding frame 41 and a second clamping cylinder 412 for driving the two second clamping arms 411 to swing in opposite directions. The upper ends of the second clamping arms 411 are hinged to the guiding frame 41, and the hinge axes of the two second clamping arms 411 are arranged in parallel, thereby realizing relative swinging of the two second clamping arms 411 to achieve clamping and release. One end of the second clamping cylinder 412 is hinged to the guiding frame 41, and the other end is hinged to the outer side of the second clamping arm 411, thereby driving the second clamping arm 411 to swing.

[0064] A belt conveyor assembly is fixedly connected to the lower end of the second clamping arm 411. When the two belt conveyor assemblies are clamped together, the conveying surfaces of the belt conveyor assemblies are in contact with each other, thereby clamping the bag opening of the packaging bag to achieve conveying.

[0065] The belt conveyor assembly includes a conveyor belt bracket 413 extending forward and backward, and a passive wheel 415 and a driving wheel 416 respectively axially connected to the two ends of the conveyor belt bracket 413. One end of the conveyor belt bracket 413 is fixedly connected to the second clamping arm 411. The conveyor belt bracket 413 is located below the clamping strip 46 at the lower end of the first clamping arm 44, so that the clamping strip 46 guides the bag opening of the packaging bag to between the two belt conveyor assemblies.

[0066] The conveyor belt 414 is also included, which is passed around the passive wheel 415 and the driving wheel 416, and a second conveying motor 418 which drives the driving wheel 416 to rotate. The driving wheel 416 is driven to rotate by the second conveying motor 418, thereby driving the conveyor belt 414 to realize circular movement.

[0067] The driving wheel 416 is connected to one end of the transmission shaft 417, and the second conveying motor 418 is connected to the other end of the transmission shaft 417 through a universal joint, wherein the center of the universal joint is located on the hinge axis of the second clamping arm 411 and the guiding frame 41, so that the swing path of the transmission shaft 417 is the same as the swing path of the second clamping arm 411.

[0068] When the traction and bag-supporting mechanism 4 is working, the packaging bags that have been bagged at the feed hopper fall onto the main conveyor belt, and the first guiding assembly retreats to the feed hopper, and the bag opening of the packaging bag is clamped by the clamping strips 46 at the lower ends of the two first clamping arms 44, and then the first guiding assembly moves forward together with the main conveyor belt, thereby guiding the packaging bags on the main conveyor belt. When the bag opening position of the packaging bag moves to between the belt conveyor assemblies at the lower ends of the second clamping arms 411 in the second guiding assembly, the bag opening of the packaging bag is clamped by the two belt conveyor assemblies, the clamping strips 46 are released, and then the packaging bags during the conveying process are guided by the cyclic movement of the guiding conveyor belt 414 in the belt conveyor assembly.

[0069] The method of using the present invention: The loading mechanism 1 first conveys the topmost packaging bag among the stacked packaging bags to the conveyor belt 13. The specific steps are as follows: multiple packaging bags are stacked on the placement plate 113, and the packaging bags are pushed to the bottom of the loading port by the loading push rod 114. The loading suction cup cylinder 118 extends downward, driving the loading suction cup frame 119 to pass through the loading port and descend to the top of one end of the packaging bag. The end of the topmost packaging bag is sucked by the loading pneumatic suction cup 120 ( Figure 7 Then the feeding suction cup cylinder 118 contracts to lift one end of the packaging bag to the top of the feeding port ( Figure 8 As shown in the state), the circulating chain 12 moves, causing the upper layer of the conveyor belt 13 to move to the left, and the packaging bags are laid flat on the conveyor belt 13 ( Figure 9 As shown in the state), the pneumatic suction cup 120 for loading is released at the same time, thereby achieving the flat loading of a single packaging bag on the conveyor belt 13.

[0070] Then the opening transfer mechanism 2 works to open the bag 5 on the conveyor belt 13 and put the bag opening at the outlet of the feed silo 3. The specific steps are as follows: the initial state of the opening transfer mechanism 2 is as follows: Figure 12 As shown, the packaging bag is transported forward by the conveyor belt of the feeding mechanism. When the front end of the packaging bag covers the support wheel 219, the upper pressure wheel 218 moves downward, pressing the packaging bag against the support wheel 219. The rotation of the support wheel 219 drives the packaging bag forward, and the baffle 216 is now in the raised state. After the packaging bag is in place, the upper pressure wheel 218 returns to its original position. The upper cylinder 28 drives the upper pneumatic suction cup 210 to descend above the bag opening, and the lower cylinder 211 drives the lower pneumatic suction cup 213 to rise below the bag opening. The upper pneumatic suction cup 210 and the lower pneumatic suction cup 213 respectively adhere to the two sides of the bag opening. The upper cylinder 28 and the lower cylinder 211 return to their original position, and the bag opening is opened. The transfer motor drives the rotating shaft 21 to rotate, causing the two opening arms 22 to swing downward, so that the support plates 23 at the ends of the opening arms 22 are inserted into the bag opening. The opening cylinder 24 is extended to drive the two opening arms 22 to swing in the opposite direction, and the two support plates 23 are respectively attached to the two ends of the opening, so that the bag opening is opened and the baffle 216 is lowered. Then the transfer motor drives the rotating shaft 21 to reset, causing the opening arms 22 to swing upward, so that the packaging bag is adjusted to a state where the bag opening is facing upward and is placed on the outlet of the feed hopper 3. At this time, the state is as follows: Figure 13 shown.

[0071] Then the feeding hopper 3 works to inject the material into the packaging bag 5. The specific steps are as follows: the opening transfer mechanism 2 puts the bag mouth of the packaging bag on the lower end of the two closed blanking plates 32, and the opening cylinder 34 drives the two blanking plates 32 to open, and presses the two sides of the bag mouth of the two packaging bags on the two limit bars 33 respectively to fix the position of the bag mouth of the packaging bag. After the blanking plates 32 are opened, the material in the silo body 31 falls into the packaging bag. At the same time, the lifting seat cylinder 313 drives the lifting seat plate 36 to descend, so that the two bag-holding rods 312 are inserted into the two end positions inside the bag mouth of the packaging bag, and then the two bag-holding sliding seats 38 move in the opposite direction, so that the two bag-holding rods 312 hold the two end positions of the bag mouth open. After the bagging is completed, the two blanking plates 32 are closed to achieve the sealing of the discharge port. At the same time, the packaging bag containing the material falls to the main conveyor belt.

[0072] When the packaging bag 5 filled with materials is conveyed on the main conveyor belt, the traction and bag supporting mechanism 4 works, clamping the bag opening of the packaging bag to achieve traction and bag supporting. The specific steps are as follows: the packaging bag completed in the feed hopper falls onto the main conveyor belt, and the first guiding assembly retreats to the feed hopper, and the bag opening of the packaging bag is clamped by the clamping strips 46 at the lower ends of the two first clamping arms 44, and then the first guiding assembly moves forward with the main conveyor belt to guide the packaging bag on the main conveyor belt. When the bag opening position of the packaging bag moves to between the belt conveyor assemblies at the lower ends of the second clamping arms 411 in the second guiding assembly, the bag opening of the packaging bag is clamped by the two belt conveyor assemblies, the clamping strips 46 are released, and then the guiding of the packaging bag during the conveying process is achieved by moving the guiding conveyor belt 414 in the belt conveyor assembly.
