Description

Technical Field

[0001] This application relates to the field of packaging, and in particular to an integrated packaging system. Background Technology

[0002] In the packaging industry, with the rapid development of the commodity economy, the demand for packaging for various products is increasing daily. Efficient, stable, and precise packaging systems play a crucial role in improving production efficiency, reducing costs, and ensuring product quality. The development of packaging systems directly affects a company's production efficiency and market competitiveness. It not only enables rapid product packaging but also protects products from external environmental influences to a certain extent, ensuring product integrity during transportation and storage. In many industries such as food, pharmaceuticals, and daily necessities, the application of packaging systems has become an indispensable part of the production process.

[0003] In traditional packaging processes, a step-by-step operation is typically employed to complete product packaging. First, manual labor or semi-automatic equipment removes the packaging bags from the bag supply area and places them at the receiving station. Then, simple mechanical devices attempt to open the bag opening. Next, manual labor or other conveying equipment transports the material above the packaging bag for unloading. After filling, simple clamping tools are used to tidy up the packaging bag to some extent, followed by sealing with simple sealing equipment. Finally, the sealed finished product is manually moved to a designated location. This traditional packaging method can meet basic packaging needs to a certain extent, but the process involves multiple steps, each requiring manual labor or simple machinery, making it relatively cumbersome.

[0004] However, traditional packaging methods have significant drawbacks. Due to the step-by-step operation, the transitions between each stage are not smooth, resulting in low packaging efficiency. Furthermore, there is a lack of precise control and effective auxiliary methods in key steps such as opening the bag, filling the material, and sealing it. Especially in vertical packaging, the material often piles up too high and is unevenly distributed inside the bag, making it difficult to flatten the film before sealing. This easily leads to wrinkles or material trapping in the sealing area, severely affecting the sealing performance and yield rate. Summary of the Invention

[0005] To overcome the shortcomings of the prior art, this application provides an integrated packaging system that can improve packaging efficiency, ensure packaging quality, ensure uniform material distribution, and ensure good sealing effect.

[0006] This application is achieved through the following technical solution: An integrated packaging system, comprising: A bag-feeding and opening mechanism is used to deliver packaging bags to the receiving station and open the bag opening; The clamping and lifting mechanism is located at the receiving station and is used to clamp the two sides of the packaging bag to cooperate with the bag feeding and opening mechanism to open the bag mouth. It is also used to drive the entire packaging bag filled with materials to be lifted upward by a set distance so as to lift the preset sealing part on the packaging bag to the sealing station. A material conveying mechanism is located above the receiving station and is used to receive materials and discharge them into the packaging bag. A shaking mechanism is located below the receiving station to support the bottom of the packaging bag and shake it back and forth to promote the settling and uniform distribution of the material inside the bag. A sealing assembly is used to close and seal the pre-set sealing portion of a packaging bag at the sealing station. The discharge assembly is used to receive and discharge the sealed finished product.

[0007] By adopting the above technical solution, this application highly integrates multiple independent processes such as bag feeding, bag opening, material receiving, shaking and evenly distributing the material, lifting and flattening, and sealing and discharging into a single material receiving station, realizing automation and integration of the entire packaging process. In particular, by using a clamping and lifting mechanism to drive the entire packaging bag after loading the material upwards by a set distance, combined with the compaction effect of the bottom shaking mechanism, the bag film in the area to be sealed can be smoothly cleared and longitudinally flattened before sealing. This effectively avoids material being trapped in the sealing area or the film being squeezed and wrinkled, significantly improving the flatness of the seal and the packaging quality of the finished product.

[0008] Optionally, the bag feeding and opening mechanism includes a transfer and adsorption assembly and a docking and opening assembly located at the receiving station; the transfer and adsorption assembly includes a first suction nozzle group and a driving device; the first suction nozzle group is used to perform negative pressure adsorption on the edge of the packaging bag in the bag feeding area to pick up the packaging bag; the driving device is used to drive the first suction nozzle group to rotate at a set angle to transport the packaging bag to the receiving station; the docking and opening assembly includes a second suction nozzle group and a translation drive for driving the second suction nozzle group to translate, and the second suction nozzle group is arranged opposite to the first suction nozzle group rotated to the receiving station; the first suction nozzle group and the second suction nozzle group are used to jointly adsorb the opposite outer surfaces of the packaging bag, and stretch and separate the bag opening of the packaging bag outward by the retraction movement of the two moving away from each other.

[0009] By adopting the above technical solution, the bag opening mechanism utilizes the coordinated action of the transfer adsorption component and the docking bag opening component to achieve a smooth transition of the packaging bag from a flat state to a precisely established receiving posture. The first suction nozzle group completes the delivery to the receiving station by flipping across the space and forms negative pressure adsorption points on opposite sides with the second suction nozzle group. Then, the bag opening is evenly pulled open to both sides by the reverse retraction movement of the two, which fundamentally overcomes the defects of slippage caused by single-sided robotic arm grasping or unstable opening caused by airflow blowing, resulting in material spillage. This significantly improves the bag opening success rate and the error tolerance rate of subsequent material dropping.

[0010] Optionally, the driving device includes a rotating shaft disposed above the bag supply area and a telescopic driving push rod with one end rotatably connected to the rotating shaft and the other end connected to the first suction nozzle assembly; the rotating shaft is connected to a rotary driving component, which is used to drive the rotating shaft to rotate so that the telescopic driving push rod drives the first suction nozzle assembly to flip, and the axial extension and retraction of the telescopic driving push rod is used to drive the first suction nozzle assembly to perform lifting, picking up and retracting movements.

[0011] By adopting the above technical solution, the drive device combines rotational motion and linear telescopic motion in a single linkage architecture. The rotating shaft is responsible for precisely controlling the flipping angle of the first suction nozzle group to cover the span between different workstations. The axial extension and retraction of the telescopic drive push rod not only meets the action requirements of picking up the packaging bag at the depth of the bag feeding area, but also directly converts it into the retraction and stretching power required for opening the bag at the receiving workstation. This design, which reuses a single execution component to complete the picking and opening actions in different time sequences, greatly simplifies the complexity of the mechanism, reduces the manufacturing cost and maintenance difficulty of the equipment, and at the same time reduces the overall inertia of the moving parts to improve the agility of the action response.

[0012] Optionally, the clamping and lifting mechanism includes clamping components, lifting drive components, and expansion components respectively distributed on both sides of the packaging bag; the movable ends of the lifting drive components on both sides are respectively connected to the clamping components on both sides, and the movable end of the expansion component is connected to the lifting drive components on both sides; the clamping components are used to laterally retract to clamp and define the side edges of the packaging bag; the expansion components are used to drive the lifting drive components and the clamping components on both sides to move away from each other, cooperating with the action of the first suction nozzle group and the second suction nozzle group to stretch and separate the bag opening outward, expanding the bag opening outward and flattening it open; the lifting drive component is used to drive the clamping components and the clamped packaging bag to lift upward to the sealing station.

[0013] By adopting the above technical solution, the clamping and lifting mechanism breaks through the limitations of traditional machinery that relies solely on suction to maintain the bag opening state. It constructs a bag opening tension and flattening dimension that combines lateral clamping and restriction with reverse expansion and stretching. The expansion component drives the clamping components on both sides to apply outward hard physical traction force to the two sides of the packaging bag, on the basis of the suction nozzle pulling the bag wall outward. This forces the entire bag opening area to form a tight and absolutely flat state, completely eliminating the random wrinkles caused by the flexible packaging material under its own weight or the impact of falling material. Then, the lifting drive component smoothly and vertically delivers the highly tensioned packaging bag to the sealing station, eliminating the hidden dangers of air leakage or poor welding caused by uneven overlapping of the bag opening from the source. This multi-axis collaborative mechanism that integrates clamping and fixing, physical expansion and displacement lifting provides a highly consistent and precise working condition prerequisite for subsequent high-quality sealing.

[0014] Optionally, the shaking mechanism includes a reciprocating shaking drive assembly for providing vertical reciprocating power and a mounting base driven by the reciprocating shaking drive assembly to perform up-and-down reciprocating motion; the mounting base can be positioned directly below the bottom of the packaging bag during the material dropping stage of the packaging bag.

[0015] By adopting the above technical solution, the shaking mechanism can be positioned directly below the bottom of the bag during the material feeding stage. The reciprocating shaking drive component drives the mounting base to perform high-frequency up-and-down reciprocating motion. The periodic physical lifting and vibration at the bottom forces loose materials or jammed workpieces inside the bag to quickly settle and tightly fit together, effectively reducing the material's accumulation height inside the bag, preventing excessive interference from the top layer material during sealing, and further optimizing the volume utilization rate of the packaging bag.

[0016] Optionally, the reciprocating vibration drive assembly includes a vertically arranged guide rail, a lead screw vertically arranged inside the guide rail, and a motor for driving the lead screw to rotate; the mounting base is slidably connected to the guide rail, and the mounting base is drively connected to the lead screw.

[0017] By adopting the above technical solution, the reciprocating vibration drive component uses a linear reciprocating transmission module composed of a guide rail, a lead screw, and a motor, which has good structural rigidity and transmission accuracy. Through direct control of the motor, the stroke amplitude and swing frequency of the up and down vibration can be conveniently and accurately adjusted to adapt to the settling and compaction requirements of materials of different materials, weights, or shapes, making the equipment more versatile.

[0018] Optionally, the discharge assembly is disposed on the shaking mechanism, including a discharge flap hinged to the mounting base and a flipping drive for driving the discharge flap to rotate; the discharge flap has a horizontal support position and an inclined discharge position; in the horizontal support position, the discharge flap abuts against the bottom of the packaging bag and shakes together with the mounting base; in the inclined discharge position, the discharge flap flips downward and tilts to guide the sealed packaging bag to slide down.

[0019] By adopting the above technical solution, the discharge component is cleverly integrated and fixed on the mounting base of the vibration mechanism, giving the discharge flap a dual functional attribute within a single work cycle. In the horizontal support position, it acts as a base plate to transmit vibration force; after sealing, it flips to the inclined discharge position, transforming into a gravity-feed slide. This reusable structural design not only reduces the transfer and docking time between processes but also greatly simplifies the overall mechanical structure and footprint of the equipment, improving the smoothness of automatic material discharge.

[0020] Optionally, the material conveying mechanism includes an inclined discharge chute; a flow guide baffle is movably provided inside the discharge chute, the flow guide baffle divides the discharge chute into two alternate material collection channels, and the flow guide baffle can swing left and right to guide the material to flow into different discharge channels; the output ends of the two discharge channels are rotatably connected to baffle plates, and the baffle plates are connected to opening and closing control components.

[0021] By adopting the above technical solution, the material conveying mechanism introduces a dual-channel feeding chute structure with guide baffles, realizing the alternating collection and rapid diversion of materials on the production line. This design allows materials continuously conveyed from the front end to arrive without interruption. While one feeding channel is discharging material into the current packaging bag, the other channel can simultaneously store and accumulate the next batch of pre-ordered materials, thereby eliminating the idle period of waiting for materials and significantly improving the system's cycle time and production efficiency.

[0022] Optionally, the material conveying mechanism further includes a discharge guide plate and a discharge pipe; one end of the discharge guide plate is connected to the output end of the discharge slide, and the other end is connected to the inner cavity of the discharge pipe; the bottom of the discharge pipe is provided with an opening and closing valve assembly.

[0023] By adopting the above technical solution, the output end of the feeding chute is connected to the discharge pipe with an opening and closing valve assembly via the feeding guide plate. The smooth transition section of the feeding guide plate effectively buffers the instantaneous impact force when the workpiece falls, while the discharge pipe and closing valve at the bottom can concentrate and gather the diverted material. When the valve opens instantaneously, it ensures that the material falls vertically into the bag opening in a concentrated form, reducing the risk of workpiece splashing or accidental spillage.

[0024] Optionally, the sealing assembly includes a first sealing module and a second sealing module located on both sides of the receiving station and arranged opposite to each other, as well as an opening and closing drive for driving the first sealing module and the second sealing module to move towards each other to clamp the packaging bag or move away from each other.

[0025] By adopting the above technical solution, the sealing assembly adopts a bidirectional symmetrical clamping arrangement of the first sealing module and the second sealing module. Under the traction of the opening and closing drive component, the two modules can move towards each other at the same speed and mold closing pressure, ensuring that the high temperature heating or pressure closing action is accurately and synchronously applied to the front and back sides of the preset sealing position without deviation. This physical clamping mechanism with balanced force on both sides resolves the defects of packaging bag backward displacement and local pulling of flexible materials that are easily caused by single-sided unidirectional pushing sealing, ensuring that the depth of the welded sealing pattern is uniform and the appearance is flat and without warping, thereby achieving a higher airtightness and tear resistance test standard.

[0026] In summary, this application includes at least one of the following beneficial technical effects: This application, through a highly integrated material receiving station layout system, organically links the action of lifting the packaging bag by a set distance with the reciprocating support and shaking at the bottom. While allowing the material to settle and fit in fully, it forcibly stretches and makes room for a flat area of ​​the film to be sealed. This solves the technical pain points of excessive interference at the top of the material and the failure of the seal due to wrinkles in the film at the bag opening during the vertical packaging process, ensuring a high yield rate for one-stop packaging operations. Based on the ingenious follow-up structure design of the translational opening suction cup and the side clamp expansion, this application realizes a high-fidelity four-point force support bag physical model while ensuring the bag body is firmly locked, reducing the bag breakage and deformation caused by hard pulling and stretching, so that the flexible packaging bag presents a square and smooth ideal opening and receiving state. This application greatly optimizes the system's operating efficiency and space through deep reuse and integration of mechanisms. It not only adopts a guide plate and dual feeding channels to achieve uninterrupted, zero-wait alternating material receiving and buffering, but also directly hinges the discharge flap onto the shaking base, cleverly realizing the dual function of flat material feeding and tilting sliding material discharge, reducing manufacturing costs and shortening the overall packaging cycle.

[0029] The technical solutions of various embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Example 1

[0030] Reference Figures 1 to 3 This application discloses an integrated packaging system, comprising: The bag feeding and opening mechanism 2 is used to deliver the packaging bag 13 to the receiving station 1 and open the bag opening of the packaging bag 13; The clamping and lifting mechanism 3 is set at the receiving station 1. It is used to clamp the two sides of the packaging bag 13 to cooperate with the bag opening mechanism 2 to open the bag mouth, and to drive the packaging bag 13 filled with materials to lift the whole bag upward by a set distance so as to lift the preset sealing part on the packaging bag 13 to the sealing station. The material conveying mechanism 5 is located above the receiving station 1 and is used to receive materials and drop them into the packaging bag 13. The shaking mechanism 4 is located below the receiving station 1 and is used to support the bottom of the packaging bag 13 and shake it back and forth to promote the material inside the bag to settle and become uniform. The sealing component 6 is used to close and seal the pre-set sealing part of the packaging bag 13 at the sealing station; The discharge component 7 is used to receive and discharge the sealed finished product.

[0031] For details, please refer to Figure 2 and Figure 3 The bag-opening mechanism 2 is composed of two independent transfer and adsorption components 21 and a docking and opening component 22. The transfer and adsorption component 21 includes an array of first suction nozzles 211 and a drive device 212 that moves them. The drive device 212 consists of a rotating shaft 2121 fixed above the bag-supply area 12 and a telescopic drive push rod 2122 pivotally connected to the rotating shaft 2121 at one end. The telescopic drive push rod 2122 is preferably a servo electric push rod with precise stroke control or a tandem cylinder. One end of the rotating shaft 2121 is connected to a rotary drive component 2123, which can be a servo motor 413 or a rotary cylinder. The output shaft of the rotary drive component 2123 is coaxially fixedly connected to the rotating shaft 2121 and is used to drive the rotating shaft 2121 to rotate around its own axis. During operation, the telescopic drive push rod 2122 extends downwards, carrying the first suction nozzle assembly 211, and uses negative pressure to suck up a packaging bag 13. Then, the rotary drive component 2123 drives the rotating shaft 2121 to rotate, causing the telescopic drive push rod 2122 to rotate the first suction nozzle assembly 211 around the rotating shaft 2121 at a certain angle. During this process, the push rod retracts, flipping the packaging bag 13 from a horizontal position to an upright position and conveying it to the predetermined center point of the receiving station 1. Simultaneously, the docking and opening assembly 22 is ready on the other side of the receiving station 1. The second suction nozzle assembly 221 within this assembly approaches under the push of the translation drive component 222 (such as a linear module). At this point, the first suction nozzle assembly 211 and the second suction nozzle assembly 221 are positioned on opposite sides of the vertically arranged packaging bag 13, and respectively activate negative pressure to suction the opposite outer surfaces of the packaging bag 13. Next, the push rod of the drive device 212 and the translation drive 222 of the bag opening assembly 22 simultaneously perform a retraction movement in opposite directions, uniformly stretching the front and rear thin sheets of the bag opening of the packaging bag 13 outward to the open state.

[0032] refer to Figure 2 and Figure 3The sealing assembly 6 is located on both sides of the receiving station 1, including a first sealing module 61 and a second sealing module 62 arranged opposite to each other on both sides of the receiving station 1, and an opening and closing drive component 63. Both the first sealing module 61 and the second sealing module 62 are mounted on guide rails 411, and each has a pre-embedded heating element that monitors the heat through a temperature control element. The opening and closing drive component 63 can be a bidirectional cylinder or a bidirectional lead screw 412 module, with its two movable ends connected to the first sealing module 61 and the second sealing module 62 respectively. It is used to drive the first sealing module 61 and the second sealing module 62 to move towards each other to clamp the preset sealing portion of the packaging bag 13, or to move away from each other to release the packaging bag 13. Once the clamping and lifting mechanism 3 has completed the upward pulling and flattening operation to clear the area to be sealed, the opening and closing drive component 63 drives the first sealing module 61 and the second sealing module 62 to quickly clamp towards each other. The films on both sides are permanently heat-melted and closed by constant temperature hot welding, and the residual film is cut off. After that, the modules are separated and reset.

[0033] refer to Figure 4 The material conveying mechanism 5 adopts a smooth material guiding posture that combines inclination and verticality. The upper part is an inclined discharge chute 51, with a guide baffle 52 hinged internally. Driven by an external swing cylinder, the guide baffle 52 swings left and right, physically dividing the discharge chute 51 into two alternate, non-interfering discharge channels 53. Each discharge channel 53 has an independently controlled baffle 54 rotatably connected to its output end. The baffle 54 is connected to an opening / closing control element, which can be a miniature opening / closing cylinder, used to drive the baffle 54 to rotate and open or close the output end of the discharge channel 53. Below the two discharge channels 53, a discharge guide plate 55, formed by bending a smooth metal plate, converges inward, one end connecting to the channel output end, and the other end naturally connecting to the inner cavity of a discharge pipe 56 with a tapered design. At the bottom of the discharge pipe 56 is a set of cylinder-driven opening / closing valve assemblies 57. It should be particularly noted that after the packaging bag 13 has descended to complete the material receiving preparation and has been flattened and opened, the bottom of this set of material receiving pipes 56 and its opening and closing valve assembly 57 are precisely positioned directly above the center of the bag opening's geometric space, maintaining a non-contact, suspended safety distance of several millimeters to one centimeter from the edge of the film at the bag opening. When the material above falls to the bottom valve, the valve is opened, and all the material, in a bundled and aggregated form, falls naturally into the bag in mid-air.

[0034] refer to Figure 5The clamping and lifting mechanism 3 is symmetrically distributed on both sides of the receiving station 1. It includes clamping components 31, lifting drive components 32, and expansion components 33, respectively distributed on both sides of the packaging bag 13. The clamping components 31 are a set of pneumatic grippers with silicone anti-slip pads. The clamping components 31 on both sides are arranged corresponding to the left and right edges of the packaging bag 13, and are used to laterally close and clamp the side edges of the packaging bag 13. The lifting drive components 32 are located below the clamping components 31, and the movable ends of the lifting drive components 32 on both sides are fixedly connected to the clamping components 31 on the corresponding sides. The lifting drive components 32 can be vertically arranged cylinders or screw lifting modules. The cylinder body or fixed seat is connected to the movable end of the expansion component 33 through a mounting plate, and its movable end (i.e., the piston rod end of the cylinder or the slider of the screw module) is connected to the clamping components 31. The lifting drive components 32 are used to drive the clamping components 31 and the packaging bag 13 they clamp to lift vertically upward to the sealing station. The expansion component 33 is mounted on the side wall frame of the receiving station 1. The expansion component 33 can be a bidirectional synchronous belt linear module or a double-rod cylinder, with its movable ends connected to the mounting plates of the lifting drive components 32 on both sides. The expansion component 33 drives the lifting drive components 32 and clamping components 31 on both sides to move horizontally away from each other, coordinating with the first suction nozzle group 211 and the second suction nozzle group 221 to stretch and separate the bag opening, thus expanding and flattening the bag opening outwards. Specifically, after the first suction nozzle group 211 and the second suction nozzle group 221 adsorb the film on the front and rear sides of the packaging bag 13, the clamping components 31 on both sides retract laterally, accurately clamping and limiting the upper edges of the left and right sides of the packaging bag 13. Subsequently, when the first suction nozzle group 211 and the second suction nozzle group 221 initiate a retraction movement to separate the film in the forward and backward direction to form an opening, the expansion component 33 drives the lifting drive components 32 and clamping components 31 on both sides to move outwards in the left and right directions. This four-point follow-up mode, with front and rear suction cups pulling and left and right clamps equidistantly following and expanding outwards, ensures that the bag opening is smoothly opened into a regular rectangular or elliptical shape, effectively preventing local twisting and wrinkling of the flexible film under strong tension. After the material receiving and even distribution actions are completed, the lifting drive components 32 on both sides synchronously drive the clamping components 31 and the clamped packaging bag 13 to lift upwards to the sealing position, thereby creating a flat and taut sealing area for subsequent sealing.

[0035] refer to Figure 6 and Figure 7The vibration mechanism 4 and the discharge assembly 7 are highly integrated here. The vibration mechanism 4 includes a reciprocating vibration drive assembly 41 composed of a servo motor 413, a vertical guide rail 411, and a lead screw 412. The forward and reverse rotation of the motor 413 can drive the nut seat and the mounting base 42 connected above it to perform high-frequency, short-stroke, rapid up-and-down reciprocating sliding along the guide rail 411. The discharge assembly 7 is directly mounted on this mounting base 42, which is in a high-frequency vibration state. The working end of the discharge assembly 7 is a discharge flap 71 controlled by a flipping cylinder as a flipping drive component 72. The end of the discharge flap 71 near the front of the equipment is hinged to the cantilever structure of the mounting base 42. During the receiving and dropping stage, the discharge flap 71 is pushed by the cylinder to maintain a horizontal support position, at which point its upper surface just abuts against the flexible bottom of the opened packaging bag 13. When the motor 413 drives the mounting base 42 to vibrate at high frequency, the discharge flap 71 transforms into a rigid support plate, synchronously striking and lifting the bottom of the packaging bag 13 at high frequency, causing the irregular materials inside to fit together and sink under the feedback of gravity and vibration. At the moment of sealing and clamping release, the push rod of the flip drive 72 quickly retracts, and the discharge flap 71, under the influence of its own weight and the guidance of the mechanism, quickly flips and tilts downward around the hinge axis, instantly changing to the tilted discharge position. At this large tilt angle, the freed fully loaded packaging bag 13 slides directly out of the equipment and leaves the workstation along the smooth flap surface.

[0036] The implementation principle of this application embodiment is as follows: After the system is started, the telescopic drive push rod 2122 of the bag feeding and opening mechanism 2 extends downward, so that the first suction nozzle group 211 adsorbs the edge of the packaging bag 13 under negative pressure in the bag feeding area 12. Then, the rotary drive component 2123 drives the rotating shaft 2121 to rotate, so that the packaging bag 13 flips to a vertical position, and the telescopic drive push rod 2122 retracts to accurately transport it to the receiving station 1. At this time, the translation drive component 222 of the docking bag opening component 22 drives the second suction nozzle group 221 to translate and fit against the rear outer surface of the packaging bag 13. Then, the clamping components 31 on both sides of the clamping and lifting mechanism 3 laterally close and clamp the left and right edges of the packaging bag 13. Then the first The second suction nozzle assembly 221 simultaneously activates negative pressure and performs a reverse retraction movement. Simultaneously, the expansion assembly 33 drives the clamping assemblies 31 on both sides to move outwards in a synchronized expansion motion. Through the four-point linkage of front-to-back suction stretching and left-to-right clamping expansion, the opening of the packaging bag 13 is flattened and opened. After the opening is open, the mounting base 42 of the shaking mechanism 4, along with the discharge flap 71 in a horizontal support position, is positioned directly below the bottom of the packaging bag 13 and abuts against the bottom of the bag to provide bottom support. At the same time, the guide baffle 52 above the material conveying mechanism 5 guides the material into the currently operating discharge channel 53. The baffle plate 54 and the bottom opening / closing valve assembly 57 open sequentially, and the material falls vertically into the packaging bag 13. 3. After a specified amount of material falls into the packaging bag 13, the reciprocating shaking drive component 41 of the shaking mechanism 4 drives the mounting base 42 and the discharge flap 71 to cause the packaging bag 13 to vibrate up and down at a high frequency, causing the loose material inside the bag to settle quickly and fit tightly. After the material is evenly distributed, the shaking mechanism 4 stops vibrating, and the lifting drive component 32 of the clamping and lifting mechanism 3 drives the clamping component 31 and the packaging bag 13 fully loaded with material to lift upwards by a set distance. The downward pull of the material inside the packaging bag 13 and the upward lifting displacement of the clamping component 31 form a counterforce, forcibly stretching the preset sealing part at the top of the packaging bag 13 longitudinally to be taut and flat. The system is positioned accurately at the sealing station. After confirming the flattening, the opening and closing drive 63 of the sealing component 6 drives the first and second sealing modules 62 to move rapidly towards each other, clamping the flat area to perform heat-melt sealing. After sealing, the first and second sealing modules 62 are reset and separated, and the clamping component 31 at the top is released simultaneously. The packaging bag 13 falls onto the discharge flap 71 under gravity. At this time, the flipping drive 72 of the discharge component 7 drives the discharge flap 71 to flip downward around the hinge axis to the inclined discharge position, guiding the sealed finished product to slide down and be discharged from the machine. Then the discharge flap 71 returns to the horizontal support position, the receiving station 1 is emptied, and the system repeats the above steps to enter the next packaging cycle.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
