Description

Technical Field

[0001] This utility model relates to the field of bagging machines, specifically to a PE bagging machine. Background Technology

[0002] Bagging machines are widely used packaging equipment with broad applications, including but not limited to packaging in industries such as food, electronics, pharmaceuticals, and precision instruments. They stack single or multiple products (such as food bags, chip bags, etc.) in a preset quantity and then insert them into an outer packaging bag to complete the bagging process. By replacing manual operation with mechanical devices, they achieve efficient and precise bagging operations. With the continuous improvement of modern industry's requirements for packaging efficiency, hygiene standards, and cost control, performance optimization of bagging machines has become an important research direction in the field of packaging machinery.

[0003] Existing bagging machines typically consist of a feeding system, a conveying system, a bagging mechanism, and a sealing device. The basic workflow is as follows: the feeding system transports stacked items to be bagged (such as food bags) to a designated location; a suction cup device opens the outer packaging bag; the stacked items are then pushed into the outer bag; and finally, the bag is sealed using heat sealing or clamping. While such equipment can partially replace manual labor, it still has significant limitations in practical applications, particularly in meeting high standards of automation, operational efficiency, and hygiene and safety.

[0004] However, existing bagging machines still have certain shortcomings: Firstly, the automation level of current packaging bagging equipment is insufficient, with most machines requiring manual assistance for feeding, positioning, or sealing operations, resulting in high labor intensity and limited production efficiency. Secondly, manual intervention may introduce contaminants (such as dust and bacteria), posing a risk of mold growth to products with high hygiene requirements, such as food bags. Thirdly, the low integration of existing bagging packaging equipment leads to poor coordination between feeding, packaging, and sealing processes, requiring additional manual intervention and adjustments, further reducing overall operational efficiency. Therefore, there is an urgent need to develop a fully automated, high-precision, and low-pollution PE bagging machine to address the deficiencies of existing bagging packaging technologies. Utility Model Content

[0005] The purpose of this utility model is to solve the above-mentioned defects and provide a PE bagging machine to address the technical problems of existing bagging machines in the background art having low automation levels, requiring manual intervention and adjustment, and affecting the production efficiency and quality of packaging.

[0006] The objective of this utility model is achieved through the following means:

[0007] A PE bagging machine includes a frame, within which are arranged a material picking station, a material sorting station, a feeding station, a bag supporting station, a heat sealing station, a bag placing station, a bag picking station, and a material unloading station. The material picking station is equipped with a material picking clamping mechanism for receiving materials and transferring them into the material sorting station. The material sorting station is equipped with a material sorting mechanism for correcting and organizing the materials. The feeding station is equipped with a feeding mechanism and a feeding exhaust shell for vacuum adsorption of the packaging bags. The bag placing station is equipped with a bag placing platform for placing the packaging bags. The bag picking station is located above the bag placing platform and is equipped with a bag picking mechanism for adsorbing and picking up the packaging bags. The bag supporting station is equipped with a bag supporting mechanism for opening the open end of the packaging bags. The heat sealing station is equipped with a heat sealing mechanism for melting and heat sealing the open end of the packaging bags.

[0008] When the bag-picking mechanism descends to adsorb the packaging bag, the feeding mechanism can drive the feeding exhaust shell to move towards the bag-picking station, allowing the bag-picking mechanism to place the packaging bag on the feeding exhaust shell. The packaging bag is then adsorbed by vacuum on the feeding exhaust shell. The feeding mechanism drives the feeding exhaust shell to move towards the bag-supporting mechanism, allowing the bag-supporting mechanism to open the opening end of the packaging bag. At the same time, the material-picking clamping mechanism clamps the material and places it in the material sorting mechanism for correction and arrangement. The material is then inserted into the packaging bag by the material-picking mechanism. The opening end of the packaging bag can be heat-sealed by the heat-sealing mechanism. The feeding mechanism drives the feeding exhaust shell to convey the product to the unloading station, where the unloading station can unload the product from the feeding exhaust shell through the unloading mechanism.

[0009] Further as described above, the material handling and clamping mechanism includes a material handling moving module, a material handling rotating drive, a material handling lifting assembly, and a material handling gripper mounted on the material handling lifting assembly. The material handling rotating drive is mounted on the material handling moving module, and the material handling lifting assembly is vertically mounted on the material handling rotating drive. The material handling lifting assembly can drive the material handling gripper to adjust its height in the vertical direction, and the material handling rotating drive can drive the material handling gripper to rotate, so that the material handling gripper can rotate into the frame or rotate to be exposed outside the frame.

[0010] It reduces the intensity of manual labor, improves the efficiency of material transfer, and avoids the pollution (such as dust and bacteria) that may be introduced by manual material handling and transfer. It solves the problems of existing equipment having high manual intervention, low efficiency and high hygiene risks.

[0011] Furthermore, the material handling mechanism includes a material handling rotary drive, a material handling rotary platform, a receiving plate, a transverse clamping assembly, and a longitudinal clamping assembly. The material handling rotary drive is installed in the frame via a material handling support plate. The drive end of the material handling rotary drive is connected to the material handling rotary platform via a rotating seat. The rotary platform is connected to the transverse clamping assembly and the longitudinal clamping assembly via a vertical plate, so that the transverse clamping assembly and the longitudinal clamping assembly are arranged transversely and longitudinally, respectively.

[0012] The material handling mechanism drives the material handling rotating platform to rotate via a material handling rotary drive component. Combined with the bidirectional correction function of the transverse clamping assembly and the longitudinal clamping assembly, it can perform multi-dimensional positioning and adjustment of the materials entering the material handling station. The transverse clamping assembly and the longitudinal clamping assembly drive two material handling clamping plates to open and close via bidirectional lead screws, clamping and correcting the materials from the horizontal and vertical directions respectively, further ensuring accurate material position and uniform posture.

[0013] Furthermore, as described above, both the transverse clamping assembly and the longitudinal clamping assembly consist of a bidirectional lead screw, two nuts at both ends of the bidirectional lead screw, and a lead screw drive motor for driving the bidirectional lead screw to rotate. The two ends of the bidirectional lead screw are connected to the vertical plate, and the two ends of the bidirectional lead screw are respectively composed of a forward rotating tooth and a reverse rotating tooth. The two nuts are symmetrically distributed on the forward rotating tooth and the reverse rotating tooth, and each of the two nuts is connected to a material feeding clamp, so that the lead screw drive motor can drive the two nuts to drive the two material feeding clamps to open and close.

[0014] The feeding structure enables fully automated conveying of packaging bags from bag picking, product placement, heat sealing, and unloading, replacing manual handling of packaging bags. This solves the problems of poor process connection and the need for manual intervention in existing equipment, thereby improving production efficiency and packaging stability.

[0015] Further, as described above, the feeding mechanism includes a feeding linear module and a sliding seat disposed on the feeding linear module. The sliding seat is connected to the feeding exhaust shell via a feeding plate. One end of the feeding exhaust shell forms a vacuum adsorption end. A heat-sealing groove for heat sealing is provided in the middle of the vacuum adsorption end. An air extraction cavity is formed inside the vacuum adsorption end, and an air extraction pipe communicating with the air extraction cavity is provided on the side of the vacuum adsorption end. A first adsorption part and a second adsorption part are formed on the vacuum adsorption end. The first adsorption part and the second adsorption part are distributed on both sides of the heat-sealing groove, and both the first adsorption part and the second adsorption part are provided with vacuum adsorption holes communicating with the air extraction cavity.

[0016] The first and second adsorption sections formed on both sides of the heat-sealing groove further ensure the stability and reliability of the adsorption of the packaging bag, so that the open end of the packaging bag can be stably adsorbed under the vacuum adsorption holes of the first and second adsorption sections, preventing the packaging bag from slipping and falling off when the feeding exhaust shell moves, and ensuring the quality of heat-sealing packaging.

[0017] Further, as described above, the opening of the heat-sealing groove extends through the upper surface of the feeding exhaust housing. A lower heat-sealing strip is connected to the heat-sealing groove via a lower pressure plate. The heat-sealing mechanism includes a mounting plate, a moving cylinder, a heat-sealing cylinder, and an upper heat-sealing strip. The mounting plate is connected to the frame, and the moving cylinder is connected to the mounting plate. The telescopic end of the moving cylinder is connected to the heat-sealing cylinder via a connecting plate. The telescopic end of the heat-sealing cylinder extends to the lower heat-sealing strip, so that the telescopic end of the heat-sealing cylinder is connected to the upper heat-sealing strip, which is paired with the lower heat-sealing strip, via a support frame.

[0018] The heat-sealing mechanism uses a moving cylinder to drive the heat-sealing cylinder and the upper heat-sealing strip to move above the heat-sealing groove, where they work in conjunction with the lower heat-sealing strip on the feeding exhaust housing to form a vertically aligned heat-sealing structure. The heat-sealing cylinder drives the upper and lower heat-sealing strips to work together, ensuring that the upper and lower heat-sealing strips accurately fit the opening of the packaging bag, achieving uniform melting and heat sealing.

[0019] Furthermore, as described above, the mounting plate is connected to a bag-opening cylinder on the side near the vacuum adsorption end. The telescopic end of the bag-opening cylinder extends toward the vacuum adsorption end, and the telescopic end of the bag-opening cylinder is connected to a bag-opening suction cup for adsorbing the opening end of the packaging bag to open the bag.

[0020] Further, as described above, the bag-supporting mechanism includes a bag-supporting fixing plate, a bag-supporting assembly, a heat-sealing auxiliary flattening assembly, a bag-supporting moving module for driving the bag-supporting assembly to move, and a flattening moving module for driving the heat-sealing auxiliary flattening assembly to move. The bag-supporting fixing plate is installed inside the frame. The bag-supporting moving module and the flattening moving module extend towards the opening of the packaging bag, allowing the bag-supporting moving module to drive the bag-supporting assembly to move towards the packaging bag and support it. The flattening moving module can drive the heat-sealing auxiliary flattening assembly to move towards the packaging bag and perform heat sealing packaging using the flattening auxiliary heat-sealing mechanism. The bag-supporting assembly consists of a bag-supporting opening and closing assembly and two symmetrically arranged bag-supporting claws. The bag-supporting opening and closing assembly is installed... The bag-supporting moving module is equipped with a bag-supporting opening and closing component connected to two bag-supporting claws via two bag-supporting moving seats. This allows the bag-supporting opening and closing component to drive the two symmetrical bag-supporting claws to expand the opening of the packaging bag. The heat-sealing auxiliary flattening component consists of the heat-sealing auxiliary opening and closing component and two symmetrically arranged flattening plates. The heat-sealing auxiliary opening and closing component is installed on the flattening moving module and connected to the two flattening plates via two flattening moving seats. This allows the heat-sealing auxiliary opening and closing component to drive the two symmetrical flattening plates to flatten the opening of the packaging bag, thereby assisting the heat-sealing mechanism in melting and heat-sealing. The heat-sealing auxiliary opening and closing component is connected to a vacuum nozzle for vacuuming the packaging bag via a lifting cylinder.

[0021] Furthermore, as described above, the bag placement platform includes a lifting assembly, a bag placement platform, and a lifting drive motor. The bag placement platform is mounted on the lifting assembly, and the lifting drive motor can drive the bag placement platform to move up and down via a screw. The bag retrieval mechanism includes a bag retrieval cylinder, a material rack, and multiple material retrieval suction plates mounted on the material rack. The bag retrieval mechanisms are paired and arranged above the bag placement platform.

[0022] Furthermore, as described above, the feeding mechanism includes a lifting cylinder and a top-feeding cylinder. The lifting cylinder is installed inside the frame, and its telescopic end extends toward the feeding mechanism and is connected to the top-feeding cylinder via a lifting plate. A discharge port is provided on one side of the frame, and the telescopic end of the top-feeding cylinder extends toward the discharge port. When the feeding mechanism moves toward the discharge port, the lifting cylinder drives the top-feeding cylinder to rise, so that the telescopic end of the top-feeding cylinder can push the packaged product on the feeding exhaust shell toward the discharge port.

[0023] The feeding exhaust housing moves along the feeding linear module towards the discharge port, allowing the lifting cylinder to drive the top-loading cylinder to rise. After rising, the top-loading cylinder is level with the feeding exhaust housing. The telescopic end of the top-loading cylinder contacts the packaged product on the feeding exhaust housing, and then the telescopic extension of the top-loading cylinder pushes the product out of the discharge port. This achieves automatic unloading after packaging, improving the automation level and production efficiency of the unloading process.

[0024] The beneficial effects of this utility model are as follows: By integrating a material handling and clamping mechanism, a material sorting mechanism, a feeding mechanism, a bag picking mechanism, a bag supporting mechanism, a heat sealing mechanism, and a material unloading mechanism within the frame, the entire process from bag picking, material picking, material sorting, bag conveying and opening, material filling, bag heat sealing to finished product unloading is fully automated. No manual assistance is required for loading, positioning, or sealing, significantly reducing labor intensity and improving packaging efficiency. Furthermore, the fully automated process reduces direct contact between humans and materials / bags, avoiding the introduction of dust, bacteria, and other contaminants that may be introduced by manual operation, thus improving product hygiene. The rational integration of each workstation within the frame ensures seamless connection between bag picking, bag placement, bag supporting, material picking, material sorting, feeding, heat sealing, and unloading processes without additional manual intervention, solving the efficiency loss problem caused by poor process connections in existing equipment and further improving the overall continuity and efficiency of the operation.

[0046] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0047] To make the technical problem to be solved, the technical solution and the beneficial effects of this utility model clearer, the following describes the solution in further detail with reference to the accompanying drawings and embodiments.

[0048] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this scheme and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0049] In this embodiment, refer to Figures 1-13The specific implementation of a PE bagging machine includes a frame 100, within which are arranged a material picking station, a material sorting station, a material feeding station, a bag supporting station, a heat sealing station, a bag placing station, a bag picking station, and a material unloading station. The material picking station is equipped with a material picking clamping mechanism 200 for receiving materials and transferring them to the material sorting station. The material sorting station is equipped with a material sorting mechanism 300 for correcting and organizing the materials. The material feeding station is equipped with a material feeding mechanism 400. The 0 is equipped with a feeding exhaust shell 401 for vacuum adsorption packaging bags, a bag placement platform 500 for placing packaging bags is provided on the bag placement station, a bag retrieval station is provided above the bag placement platform 500, and a bag retrieval mechanism 600 for adsorbing packaging bags and retrieving materials is provided on the bag retrieval station, a bag supporting mechanism 700 for opening the opening end of the packaging bag is provided on the bag supporting station, and a heat sealing mechanism 800 for melting and heat sealing the opening end of the packaging bag is provided on the heat sealing station.

[0050] When the bag-picking mechanism 600 descends to adsorb the packaging bag, the feeding mechanism 400 drives the feeding exhaust shell 401 to move towards the bag-picking station, allowing the bag-picking mechanism 600 to place the packaging bag on the feeding exhaust shell 401. The packaging bag is then vacuum-adsorbed onto the feeding exhaust shell 401. The feeding mechanism 400 drives the feeding exhaust shell 401 to move towards the bag-supporting mechanism 700, allowing the bag-supporting mechanism 700 to open the opening end of the packaging bag. Simultaneously, the material-picking clamping mechanism 200 clamps the material and places it in the material sorting mechanism 300 for correction and arrangement. The material is then inserted into the packaging bag by the material-picking mechanism. The heat-sealing mechanism 800 heat-seals the opening end of the packaging bag. The feeding mechanism 400 drives the feeding exhaust shell 401 to convey the product into the unloading station, where the unloading mechanism 900 unloads the product from the feeding exhaust shell 401.

[0051] A feed inlet 101 is provided on one side of the frame 100 near the material handling mechanism 200, and a discharge outlet 102 is provided on the other side of the frame 100 opposite to the feed inlet 101. The material handling claws 204 of the material handling mechanism 200 can pass through the feed inlet 101 and be exposed to the outside of the frame 100.

[0052] Reference Figures 3-5The material handling and clamping mechanism 200 includes a material handling moving module 201, a material handling rotating drive 202, a material handling lifting assembly 203, and a material handling gripper 204 mounted on the material handling lifting assembly 203. The material handling rotating drive 202 is mounted on the material handling moving module 201 via a moving plate 205. The material handling lifting assembly 203 is vertically arranged on the material handling rotating drive 202. The material handling lifting assembly 203 can drive the material handling gripper 204 to be lifted and adjusted vertically. The material handling rotating drive 202 can drive the material handling gripper 204 to rotate, so that the material handling gripper 204 can rotate into the frame 100 or rotate to be exposed outside the frame 100.

[0053] The material handling rotary drive 202 is composed of a rotary cylinder, and the material handling lifting assembly 203 is composed of a vertically arranged material handling screw module. One end of the material handling screw module is connected to the rotating part of the rotary cylinder, so that the rotary cylinder can drive the material handling screw module to rotate. This allows the material handling rotary drive 202 to drive the material handling lifting assembly 203 to rotate the material handling gripper 204 into the frame 100 or expose it on the outside of the frame 100, facilitating connection with external material conveying equipment. The material handling gripper 204 is clamped from the top... The assembly consists of a lower gripper 2041 and a lower gripper 2042. The lower gripper 2042 is connected to the slide of the material handling screw module. A gripper cylinder 2043 is installed on the slide. The telescopic end of the gripper cylinder 2043 is connected to the upper gripper 2041, so that the gripper cylinder 2043 can drive the upper gripper 2041 to open and close relative to the lower gripper 2042 to form a loosening or clamping action. The material handling lifting component 203 can adjust the gripper height to adapt to materials of different sizes, and the material handling moving module 201 realizes precise horizontal transfer.

[0054] Specifically, the material picking rotation drive 202 drives the material picking lifting assembly 203 and coordinates with the movement of the material picking moving module 201, so that the material picking gripper 204 is exposed outside the frame 100. The material picking screw module drives the material picking gripper 204 to adjust to the corresponding loading position, so that the material picking gripper 204 clamps the corresponding material (food bag or chip bag) and rotates into the frame 100. The clamped material (food bag or chip bag) is placed on the receiving plate 303. After the material sorting mechanism 300 rotates and corrects, the material picking gripper 204 clamps the product and inserts it into the opened packaging bag for bagging.

[0055] Reference Figure 6The material handling mechanism 300 includes a material handling rotary drive 301, a material handling rotary platform 302, a receiving plate 303, a transverse clamping assembly 304, and a longitudinal clamping assembly 305. The material handling rotary drive 301 is installed in the frame 100 through a material handling support plate 306. The drive end of the material handling rotary drive 301 is connected to the material handling rotary platform 302 through a rotating seat 307. The rotary platform is connected to the transverse clamping assembly 304 and the longitudinal clamping assembly 305 through a vertical plate, so that the transverse clamping assembly 304 and the longitudinal clamping assembly 305 are arranged transversely and longitudinally, respectively.

[0056] The material handling mechanism 300 drives the material handling rotating platform 302 to rotate via the material handling rotating drive component 301. Combined with the bidirectional correction function of the transverse clamping component 304 and the longitudinal clamping component 305, it can perform multi-dimensional positioning and adjustment of the materials entering the material handling station. The transverse clamping component 304 and the longitudinal clamping component 305 drive two material handling clamping plates 308 to open and close via bidirectional lead screws, clamping and correcting the materials from the horizontal and longitudinal directions respectively, ensuring accurate material position and uniform posture.

[0057] Specifically, the receiving plate 303 is provided with a clearance groove for avoiding the lower gripper 2042, so that the lower gripper 2042 can pass through the clearance groove under the drive of the material picking moving module 201, and the material can be placed on the receiving plate 303 so that the lower gripper 2042 can be taken out.

[0058] Both the transverse clamping assembly 304 and the longitudinal clamping assembly 305 consist of a bidirectional lead screw, two nuts at both ends of the bidirectional lead screw, and a lead screw drive motor for driving the bidirectional lead screw to rotate. The two ends of the bidirectional lead screw are connected to the vertical plate, and the two ends of the bidirectional lead screw are respectively composed of forward rotating teeth and reverse rotating teeth. The two nuts are symmetrically distributed on the forward rotating teeth and the reverse rotating teeth. Each of the two nuts is connected to a material feeding clamp 308, so that the lead screw drive motor can drive the two nuts to drive the two material feeding clamps 308 to open and close.

[0059] The material handling rotation drive 301 is composed of a rotary motor, and the rotation shaft of the rotary motor is connected to the material handling rotation platform 302 through the rotary seat 307, so that the drive of the rotary motor can drive the material handling rotation platform 302 to rotate.

[0060] Specifically, the bidirectional movement of the transverse clamping assembly 304 can drive the two transverse material handling clamps 308 to open and close, thus tidying up the edges of the material. Similarly, the bidirectional movement of the longitudinal clamping assembly 305 can drive the two longitudinal material handling clamps 308 to open and close, thus tidying up the edges of the material. This completes the material handling process.

[0061] Reference Figure 7The feeding mechanism 400 includes a feeding linear module 402 and a sliding seat 403 disposed on the feeding linear module 402. The sliding seat 403 is connected to the feeding exhaust shell 401 through a feeding plate 404. One end of the feeding exhaust shell 401 forms a vacuum adsorption end. A heat-sealing groove 4012 for heat sealing is opened in the middle of the vacuum adsorption end. An air extraction cavity 4011 is formed inside the vacuum adsorption end. An air extraction pipe 405 communicating with the air extraction cavity 4011 is opened on the side of the vacuum adsorption end. A first adsorption part 4013 and a second adsorption part 4014 are formed on the vacuum adsorption end. The first adsorption part 4013 and the second adsorption part 4014 are distributed on both sides of the heat-sealing groove 4012. A vacuum adsorption hole 4015 communicating with the air extraction cavity is opened on both the first adsorption part 4013 and the second adsorption part 4014.

[0062] The feeding mechanism 400 drives the sliding seat 403 to move via the feeding linear module 402, causing the feeding exhaust shell 401 to automatically transfer between the bag picking station, bag supporting station, heat sealing station, and unloading station. The vacuum adsorption end of the feeding exhaust shell 401 forms a negative pressure with the vacuum adsorption hole 4015 through the air extraction cavity 4011, which can stably adsorb the packaging bag and prevent the packaging bag from slipping or shifting during the transfer process; the design of the heat sealing groove 4012 provides assistance to the heat sealing mechanism 800, ensuring that it cooperates with the heat sealing mechanism 800 to complete the heat sealing.

[0063] Specifically, the feeding linear module 402 is composed of a feeding screw module. One end of the feeding screw module extends toward the inlet 101, and the other end of the feeding screw module extends toward the outlet 102, so that the feeding screw module housing drives the feeding exhaust housing 401 to reciprocate toward the material picking clamping mechanism 200 and the bag picking mechanism 600.

[0064] When the bag-picking mechanism 600 needs to pick up a packaged bag, the feeding exhaust shell 401 moves away from the bag-picking mechanism 600 along the feeding linear module, allowing the bag-picking mechanism 600 to descend towards the bag-placing platform 500 and pick up the topmost packaged bag. The bag-picking mechanism 600 then rises and resets. At this time, the feeding exhaust shell 401 moves along the feeding linear module 402 to below the bag-picking mechanism 600, allowing the bag-picking mechanism 600 to place the picked-up packaged bag on top of the feeding exhaust shell 401. The feeding exhaust shell 401 then applies negative pressure to the packaged bag through the vacuum adsorption end.

[0065] The feeding structure enables fully automated conveying of packaging bags from bag picking, product placement, heat sealing, and unloading, replacing manual handling of packaging bags. This solves the problems of poor process connection and the need for manual intervention in existing equipment, thereby improving production efficiency and packaging stability.

[0066] Reference Figure 13The opening of the heat-sealing groove 4012 extends through the upper surface of the feeding exhaust shell 401. A lower heat-sealing strip 805 is connected to the heat-sealing groove 4012 through a lower pressure plate. The heat-sealing mechanism 800 includes a mounting plate 801, a moving cylinder 802, a heat-sealing cylinder 803, and an upper heat-sealing strip 804. The mounting plate 801 is connected to the frame 100. The moving cylinder 802 is connected to the mounting plate 801. The telescopic end of the moving cylinder 802 is connected to the heat-sealing cylinder 803 through a connecting plate 806. The telescopic end of the heat-sealing cylinder 803 extends to the lower heat-sealing strip 805, so that the telescopic end of the heat-sealing cylinder 803 is connected to the upper heat-sealing strip 804, which is paired with the lower heat-sealing strip 805, through a support frame 807.

[0067] The heat-sealing mechanism 800, driven by the moving cylinder 802, moves the heat-sealing cylinder 803 and the upper heat-sealing strip 804 above the heat-sealing groove 4012, cooperating with the lower heat-sealing strip 805 set on the feeding exhaust shell 401 to form an upper and lower aligned heat-sealing structure. The heat-sealing cylinder 803 drives the upper heat-sealing strip 804 and the lower heat-sealing strip 805 to cooperate, ensuring that the upper heat-sealing strip 804 and the lower heat-sealing strip 805 accurately fit the opening end of the packaging bag, achieving uniform melting and heat sealing.

[0068] Reference Figure 13 The mounting plate 801 is connected to a bag-opening cylinder 708 near the vacuum adsorption end. The telescopic end of the bag-opening cylinder 708 extends towards the vacuum adsorption end, and the telescopic end of the bag-opening cylinder 708 is connected to a bag-opening suction cup 709 for adsorbing the opening end of the packaging bag to open it. By driving the bag-opening cylinder 708 to adsorb the upper layer of the packaging bag, and in conjunction with the adsorption of the vacuum adsorption end, the bag-opening process can be completed.

[0069] The bag-opening cylinder 708, connected to a telescopic end by a bag-opening suction cup 709, adheres to both sides of the opening end of the packaging bag. Combined with the action of the bag-supporting mechanism 700, it automatically expands the opening of the packaging bag. The suction force of the bag-opening suction cup 709 is stable, avoiding problems such as tearing or insufficient opening of the packaging bag caused by uneven force during manual bag opening. This structure replaces manual bag opening, improving the automation level and reliability of the bag-opening process.

[0070] Reference Figures 9-11The bag-supporting mechanism 700 includes a bag-supporting fixing plate 701, a bag-supporting assembly 702, a heat-sealing auxiliary flattening assembly 703, a bag-supporting moving module 704 for driving the bag-supporting assembly 702 to move, and a flattening moving module 705 for driving the heat-sealing auxiliary flattening assembly 703 to move. The bag-supporting fixing plate 701 is installed inside the frame 100. The bag-supporting moving module 704 and the flattening moving module 705 extend towards the opening of the packaging bag, so that the bag-supporting moving module 704 can drive the bag-supporting assembly 702 to move toward the packaging bag and support it. The flattening moving module 705 can drive the heat-sealing auxiliary flattening assembly 703 to move toward the packaging bag and heat-seal it using the flattening auxiliary heat-sealing mechanism 800. The bag-supporting assembly 702 consists of a bag-supporting opening and closing assembly 7021 and two symmetrically arranged bag-supporting claws 7022. The bag-supporting opening and closing assembly 7021 is installed on the bag-supporting moving module 704. On module 704, the bag opening and closing component 7021 is connected to two bag opening claws 7022 respectively through two bag opening moving seats, so that the bag opening and closing component 7021 can drive the two symmetrical bag opening claws 7022 to expand the opening of the packaging bag. The heat sealing auxiliary flattening component 703 is composed of heat sealing auxiliary opening and closing component 7031 and two symmetrically arranged flattening plates 7032. The heat sealing auxiliary opening and closing component 7031 is installed on the flattening moving module 705, and the heat sealing auxiliary opening and closing component 7031 is connected to the two flattening plates 7032 respectively through two flattening moving seats, so that the heat sealing auxiliary opening and closing component 7031 can drive the two symmetrical flattening plates 7032 to flatten the opening of the packaging bag, so as to assist the heat sealing mechanism 800 in melting and heat sealing. The heat sealing auxiliary opening and closing component 7031 is connected to a vacuum nozzle 707 for vacuuming the packaging bag through a lifting cylinder 706.

[0071] The bag-supporting mechanism 700 drives the bag-supporting opening and closing component 7021 to move through the bag-supporting moving module 704, which in turn drives the two bag-supporting claws 7022 to open and close symmetrically, thereby expanding the opening of the packaging bag. This can be used in conjunction with the material-picking and clamping mechanism 200 to fill materials, thus facilitating the material-picking and clamping mechanism 200 to insert the clamped material into the packaging bag.

[0072] The flattening and moving module 705 drives the heat-sealing auxiliary flattening component 703 to move closer to the opening of the packaging bag. Through the heat-sealing auxiliary flattening and moving module, two flattening plates 7032 open and close symmetrically, flattening the packaging bag opening and making it even. The flattening plates 7032 eliminate wrinkles in the packaging bag opening, and air is drawn from the packaging bag through the vacuum nozzle 707, enabling the auxiliary heat-sealing mechanism 800 to achieve a smooth heat seal. This improves the automation level of the bag-supporting and heat-sealing processes and enhances packaging quality.

[0073] Reference Figure 8The bag-placing platform 500 includes a top material lifting assembly 501, a bag-placing platform 502, and a lifting drive motor 503. The bag-placing platform 502 is mounted on the top material lifting assembly 501. The lifting drive motor 503 can drive the bag-placing platform 502 to perform lifting and lowering movements through a screw. The bag-picking mechanism 600 includes a bag-picking cylinder 601, a material rack 602, and multiple material-picking adsorption plates 603 set on the material rack 602. The bag-picking mechanisms 600 are paired and arranged above the bag-placing platform 500.

[0074] The bag placement platform 500 is driven to raise and lower the bag placement table 502 via a lifting drive motor 503, which can automatically adjust the stacking height of the packaging bags to ensure that the bag picking mechanism 600 can always stably pick up the top layer of packaging bags. The bag picking cylinder 601 drives multiple picking and suction plates 603 on the material rack 602 to pick up the top layer of packaging bags on the bag placement table 502, causing the feeding exhaust shell 401 to move below the bag picking mechanism 600 to receive the bags. This structure realizes automatic feeding and picking of packaging bags, replacing manual handling and placement of packaging bags, while avoiding the contamination that may be introduced by manual bag picking, and improving the automation level and stability of the feeding process.

[0075] The bag placement platform 502 can hold the corresponding packaging bags. The bag picking cylinder 601 can drive the picking suction plate 603 to pick up the packaging bags on the bag placement platform 502, so that it picks up one packaging bag at a time. It also works with the feeding exhaust shell 401 to pick up the packaging bags and transport them into the packaging area for bagging.

[0076] Specifically, the top material lifting assembly 501 consists of a bushing and a guide shaft. The top material lifting assembly 501 is installed in the frame 100 through a connecting plate. The guide shaft is coaxially connected to the bushing. One end of the guide shaft is connected to the bag placing platform 502. The lifting drive motor 503 is connected to the connecting plate and the bag placing platform 502 through a lead screw, so that the rotation of the lead screw can drive the bag placing platform 502 to perform lifting and lowering actions.

[0077] Reference Figure 13 The feeding mechanism 900 includes a lifting cylinder 901 and a top-feeding cylinder 903. The lifting cylinder 901 is installed inside the frame 100, and the telescopic end of the lifting cylinder 901 extends toward the feeding mechanism 400 and is connected to the top-feeding cylinder 903 through a lifting plate 902. A discharge port 102 is provided on one side of the frame 100. The telescopic end of the top-feeding cylinder 903 extends toward the discharge port 102. When the feeding mechanism 400 moves toward the discharge port 102, the lifting cylinder 901 drives the top-feeding cylinder 903 to rise, so that the telescopic end of the top-feeding cylinder 903 can push the packaged product on the feeding exhaust shell 401 toward the discharge port 102.

[0078] The specific packaging process in this embodiment is as follows:

[0079] Bag Retrieval: Place the packaging bag on the bag placement platform 502. Drive the material rack 602 through the bag retrieval cylinder 601 to move the four material retrieval adsorption plates 603 distributed at the four corners down to the bag placement platform 502, so that the material retrieval adsorption plates 603 can adsorb and retrieve the top layer of packaging bag. The material retrieval cylinder can drive the packaging bag to rise. At the same time, the feeding linear module 402 can drive the feeding exhaust shell 401 to move to the bottom of the material retrieval mechanism. At this time, the material retrieval adsorption plate 603 places the adsorbed packaging bag on the feeding exhaust shell 401, so that the feeding exhaust shell 401 adsorbs and positions the packaging bag through the vacuum adsorption hole 4015 of the vacuum adsorption end.

[0080] Bag opening: The feeding exhaust shell 401 adsorbs the packaging bag and moves along the feeding straight module 402 into the packaging area. At this time, the bag opening cylinder 708 drives the bag opening suction cup 709 to move towards the opening end of the packaging bag, so that the bag opening suction cup 709 adsorbs the upper layer of the packaging bag and completes the opening of the packaging bag under the drive of the bag opening cylinder 708.

[0081] Bag opening: The bag opening and closing assembly 7021 is driven to move by the bag opening moving module 704, so that the two bag opening claws 7022 are inserted into the opening of the packaging bag. The bag opening and closing assembly 7021 drives the two bag opening claws 7022 to open away from each other, which can expand the opening of the packaging bag to facilitate the subsequent filling of materials.

[0082] Material handling: The material handling rotary drive 202 drives the material handling lifting assembly 203 and moves in conjunction with the material handling moving module 201, so that the material handling gripper 204 is exposed outside the feed port 101 of the frame 100. The material handling screw module drives the material handling gripper 204 to adjust to the corresponding loading position, so that the material handling gripper 204 clamps the food bag and rotates it into the frame 100. This allows the material handling clamping mechanism 200 to be connected to the external material conveyor line to realize a fully automatic production process.

[0083] Material sorting: The food bag held by the picking claw 204 is placed on the receiving plate 303. The material sorting rotation drive 301 can drive the material sorting rotation platform 302 to rotate the receiving plate 303. The material sorting clamping plate 308 is driven by the horizontal clamping assembly 304 and the vertical clamping assembly 305 to correct and sort the edges of the food bag.

[0084] Bagging: The food bag is gripped again by the picking claw 204 and inserted into the opened packaging bag for filling, thereby realizing the automated production of bagging packaging of food bags;

[0085] Flattening and heat sealing: When the food bag is placed inside the packaging bag, the bag opening and closing component 7021 drives the two bag opening claws 7022 to move closer to each other, and the bag opening and closing component 7021 is driven to move in the opposite direction by the bag opening and closing module 704, so that the bag opening claws 7022 retract from the opening of the packaging bag. At this time, the flattening moving module 705 drives the heat sealing auxiliary flattening component 703 to move closer to the opening of the packaging bag, and the heat sealing auxiliary flattening moving component drives the two flattening plates 7032 to pass through the opening of the packaging bag. When the heat-sealing auxiliary flattening moving component drives the two flattening plates 7032 to move away from each other, the opening of the packaging bag can be flattened. At the same time, the heat-sealing auxiliary flattening component 703 drives the vacuum nozzle 707 to pass through the opening of the packaging bag, so that the heat-sealing cylinder 803 drives the upper heat-sealing strip 804 to contact the packaging bag, and the vacuum nozzle 707 evacuates the packaging bag. With the help of the upper heat-sealing strip 804 and the lower heat-sealing strip 805, the packaging bag is heat-sealed, thereby completing the bagging of the food bag.

[0086] Material feeding: The feeding exhaust shell 401 moves along the feeding linear module 402 towards the discharge port 102, so that the lifting cylinder 901 can drive the top material cylinder 903 to rise. After the top material cylinder 903 rises, it is level with the height of the feeding exhaust shell 401. The telescopic end of the top material cylinder 903 contacts the packaged product on the feeding exhaust shell 401, and then the product is pushed out towards the discharge port 102 by the telescopic extension of the top material cylinder 903, thereby completing the packaging of the food bag.

[0087] In summary, the PE bagging machine allows for seamless integration of processes such as bag picking, bag placement, bag opening, material picking, material sorting, feeding, heat sealing, and unloading, eliminating the need for additional manual intervention and avoiding contaminants such as dust and bacteria that may be introduced through manual operation. This improves the hygiene quality of the products. Furthermore, the rational integration and layout of each workstation within the 100mm frame solves the efficiency loss problem caused by poor process integration in existing equipment, further enhancing the overall continuity and efficiency of the operation.
