Description

Technical Field

[0001] This utility model relates to packaging equipment, specifically to a bag-in-bag packaging device. Background Technology

[0002] Bagging equipment is a type of machinery used for automated bagging of materials. Currently, most bagging equipment on the market can only perform one bagging operation, meaning it can only fill one packaging bag at a time. However, in actual packaging processes, products like exam papers typically need to be first bagged with plastic film, and then the plastic bag containing the exam papers needs to be placed into a paper envelope to complete the entire packaging process. Traditionally, after the material is bagged for the first time, it is manually collected and sent to a second packaging machine for bagging, which is very labor-intensive for workers. Furthermore, traditional bagging equipment also suffers from problems such as poor bag-opening and sealing quality. Utility Model Content

[0003] In view of the deficiencies in the prior art, the technical problem to be solved by this utility model is to provide a bag-in-bag packaging device for solving the above-mentioned problems.

[0004] Therefore, this utility model is implemented using the following solution:

[0005] A bag-in-bag packaging device, characterized in that it includes a first bag packaging mechanism and a second bag packaging mechanism. The first bag packaging mechanism includes a first bag feeding assembly, a first bag conveyor belt, a first bag opening and spreading assembly, a first bag filling assembly, and a first bag sealing assembly. The second bag packaging mechanism includes a second bag feeding assembly, a second bag conveyor belt, a second bag opening and spreading assembly, a second bag filling assembly, and a second bag sealing assembly. The discharge end of the first bag conveyor belt is connected to the inlet end of a transition conveyor belt, and the discharge end of the transition conveyor belt is connected to the inlet end of the second bag filling assembly.

[0006] The first bag opening and stretching assembly includes a bag opening suction nozzle and left and right bag stretching plates. The bag opening suction nozzle is mounted on a liftable suction nozzle frame, and the bag stretching plates are mounted on corresponding swing blocks. The swing blocks are movably mounted on a first movable seat and connected to a swing drive assembly. The first movable seat is connected to the first movable drive assembly. When the bag is stretched, the first movable drive assembly first drives the first movable seat to move, so that the two bag stretching plates extend longitudinally into the opened packaging bag. Then, the swing drive assembly drives the swing blocks to swing, so that the bag stretching plates swing outward to stretch the bag opening.

[0007] The first sealing assembly includes a heat-sealing cutter, which is connected to a first lifting drive assembly. A blade strip is provided corresponding to the heat-sealing cutter. The heat-sealing cutter and the blade strip work together to cut and heat-seal the opening of the packaging bag.

[0008] A first gripper and a second gripper are provided on the left and right sides of the heat-sealing cutter. The first gripper is movably mounted on a second movable seat, which is connected to a second moving drive assembly. The second gripper is movably mounted on a third movable seat, which is connected to a third moving drive assembly. The second and third movable seats are movably mounted on a fourth movable seat, which is connected to a fourth moving drive assembly.

[0009] On both sides of the bag opening component, there are also gluing components and folding plates. The gluing components are used to apply glue to the outer extension of the bag opening. The folding plates can squeeze and drive the glued outer extension to fold upward. A first pusher is provided on one side of the folding plates. The first pusher can push the folded outer extension to fold downward and stick it to the outer wall of the bag to seal the bag.

[0010] The first bagging assembly includes a first feeding platform, and a movable frame is provided at the discharge end of the first feeding platform. The movable frame is connected to a movable drive assembly, and a gripper assembly is provided on the movable frame. The gripper assembly is used to clamp the stacked materials on the first feeding platform and then drive the materials to move and feed them into the opened packaging bag.

[0011] The second sealing assembly includes a glue spraying assembly and a second pusher arranged sequentially along the moving path of the second bag conveyor belt. The second pusher is connected to a fifth moving drive assembly. The second pusher and the fifth moving drive assembly are mounted on a first lifting seat. The first lifting seat is connected to the second lifting drive assembly. A crease plate is provided on one side corresponding to the second pusher. The crease plate is connected to a sixth moving drive assembly. When the second pusher rises, it cooperates with the crease plate to achieve the positioning and upward folding of the outer extension of the bag opening.

[0012] The aforementioned bag-in-bag packaging equipment, through a rationally arranged structure, connects the first and second bag packaging mechanisms together. After the first bag packaging mechanism completes its first bagging, the material is directly delivered to the second bagging component of the second packaging mechanism, enabling continuous second bagging operations. This achieves automated bag-in-bag packaging, eliminating the need for manual stacking and collection of the first bagged material, further enhancing automation and reducing worker workload. Furthermore, the innovative design of a movable bag-supporting structure adapts to different bag sizes and improves bag-supporting quality. The innovative heat-sealing structure also adapts to film-type packaging bags, effectively improving sealing quality. Attached Figure Description

[0024] As shown in the figure, this utility model discloses a bag-in-bag packaging device, including a first bag packaging mechanism and a second bag packaging mechanism. The first bag packaging mechanism includes a first bag feeding component 1, a first bag conveyor belt 2, a first bag opening and spreading component 3, a first bag filling component 4, and a first bag sealing component 6. The second bag packaging mechanism includes a second bag feeding component 12, a second bag conveyor belt 13, a second bag opening and spreading component 14, a second bag filling component 11, and a second bag sealing component 15. The discharge end of the first bag conveyor belt 2 is connected to the inlet end of the transition conveyor belt 8, and the discharge end of the transition conveyor belt 8 is connected to the inlet end of the second bag filling component 11. A pushing component 9 is provided corresponding to the discharge end of the transition conveyor belt 8. The pushing component is used to push the material that has been bagged once to the second feeding platform 10 of the second bag filling component 11. The pushing component adopts a common pushing block on the market, which is driven by a cylinder, linear motor, or other structure. Therefore, its specific structure will not be described in detail. Push rods are provided for the first and second feeding platforms to push the material closer to the bag opening.

[0025] Furthermore, the first bag-opening and opening assembly includes a bag-opening suction nozzle 20 and left and right supporting plates 16. The bag-opening suction nozzle 20 is mounted on a liftable suction nozzle frame 21. A corresponding cylinder drives the suction nozzle frame 21 to rise and fall, sucking up and lifting the packaging bag through the bag-opening suction nozzle 20, thereby opening the bag opening. The supporting plates 16 are mounted on a corresponding swing block 17. The swing block 17 is movably mounted on the first movable seat 19 and connected to the swing drive assembly. The swing drive assembly includes a second cylinder 23. The piston rod of the second cylinder 23 is hinged to one end of the first swing arm 22. The other end is connected to the first drive shaft 18, which is rotatably mounted on the first movable seat 19 and connected to the swing block 17. The first movable seat 19 is connected to the first moving drive assembly, which is a first cylinder 24. The piston rod of the first cylinder 24 is connected to the first movable seat 19. When the bag is opened, the first moving drive assembly first drives the first movable seat 19 to move, causing the two bag-opening plates 16 to extend longitudinally into the open packaging bag. Then, the swing drive assembly drives the swing block 17 to swing, causing the bag-opening plates 16 to swing outward and open the bag opening. With the above structure, the bag-opening plates 16 can first extend into the open packaging bag, and then the bag-opening plates 16 can be controlled to swing and open the packaging bag. This can adapt to packaging bags of different sizes and ensure the quality of bag opening.

[0026] Furthermore, the first sealing assembly includes a heat-sealing cutter 28, which is connected to a first lifting drive assembly, which is a corresponding cylinder. A blade strip 27 is provided corresponding to the heat-sealing cutter 28. The heat-sealing cutter 28 and the blade strip 27 cooperate to cut and heat-seal the opening of the packaging bag. Using this structure, heat-sealing and cutting of non-adhesive-resistant packaging bags can be achieved, further improving the sealing quality.

[0027] Furthermore, a first gripper 29 and a second gripper are provided on the left and right sides of the heat-sealing cutter 28. The first gripper 29 is movably mounted on the second movable seat 30, which is connected to the second moving drive assembly. The second gripper is movably mounted on the third movable seat 32, which is connected to the third moving drive assembly. The second and third movable seats are movably mounted on the fourth movable seat 31, which is connected to the fourth moving drive assembly. The second, third, and fourth moving drive assemblies are corresponding cylinders. With the above structure, before sealing the bag, the fourth movable seat 31 can be controlled to move, causing the first and second grippers to move to the bag opening and clamp it. Then, the second and third movable seats can be controlled to move away from each other, thereby pulling the bag opening flat and ensuring that the bag opening is flat before heat sealing, thus ensuring the flatness of the bag opening after heat sealing.

[0028] Furthermore, an adhesive application component 33 and a folding plate 25 are respectively provided on both sides of the first bag opening component. The adhesive application component 33 is used to apply adhesive to the outer extension of the bag opening. The adhesive application component 33 is a common double-sided adhesive application structure, which is existing technology, so its specific structure will not be described in detail. The folding plate 25 can squeeze and drive the already adhesive outer extension to fold upward. A first pusher 26 is provided on one side of the folding plate 25. The first pusher 26 can push the folded outer extension downward to adhere to the outer wall of the bag, thereby sealing the bag. Using the above structure, when sealing the adhesive bag, adhesive can first be sprayed onto the outer extension of the bag opening through the adhesive application component 33, then the folding plate 25 can squeeze and guide the outer extension to fold upward, and then the first pusher 26 can be controlled to move and drive the outer extension to fold downward and inward to adhere to the outer wall of the bag, thus completing the adhesive sealing operation.

[0029] Furthermore, the first bagging assembly includes a first feeding platform 5, with a movable frame 35 corresponding to the discharge end of the first feeding platform 5. The movable frame 35 is connected to a movable drive assembly, and a gripper assembly 38 is provided on the movable frame 35. The gripper assembly 38 is used to clamp the stacked materials on the first feeding platform 5 and then move the materials to be fed into the opened packaging bag. A lifting bar 37 is provided corresponding to the discharge end of the first feeding platform 5, and the feeding end of the lifting bar 37 has an inclined surface 36, so that the stacked materials can be supported by the lifting bar 37 and its bottom is suspended, making it convenient for the gripper assembly 38 to clamp the stacked materials. The movable frame 35 is connected to a rotating shaft 34, and the rotating shaft 34 is connected to one end of a second transmission arm. The other end of the second transmission arm is connected to a corresponding cylinder. By controlling the cylinder to drive the transmission arm to swing, the rotating shaft 34 can be driven to rotate, causing the movable frame 35 to swing. The movable frame 35 is set on a sliding frame 39, and the sliding frame 39 is connected to a corresponding linear motor 40 to realize the horizontal movement control of the movable frame 35. Using the above structure, the material can be first positioned and clamped before being fed into the packaging bag, ensuring that the material will not become loose or shift during the process of being fed into the packaging bag.

[0030] Furthermore, the second sealing assembly includes a glue spraying assembly 41 and a second pusher 42 arranged sequentially along the moving path of the second bag conveyor belt 13. The second pusher 42 is connected to the fifth moving drive assembly. The second pusher 42 and the fifth moving drive assembly are arranged on the first lifting seat 43. The first lifting seat 43 is connected to the second lifting drive assembly. A crease plate 44 is provided on one side corresponding to the second pusher 42. The crease plate 44 is connected to the sixth moving drive assembly. When the second pusher 42 rises, it cooperates with the crease plate 44 to achieve the positioning and folding of the outer extension of the bag opening. The fifth and sixth moving drive components and the second lifting drive component are corresponding cylinders. By adopting the above mechanism, when the outer packaging bag is delivered to the glue spraying component 41, glue is first sprayed on the outer extension of the bag opening. Then, when the packaging bag is delivered to the second pusher 42, the crease plate 44 is first controlled to move to the bag opening to press the bag opening tightly. The first lifting seat 43 is controlled to drive the second pusher 42 to rise, squeezing the outer extension of the bag opening to fold upward along the crease plate 44. Then, the crease plate 44 is controlled to reset and drive the second pusher 42 to move to squeeze the outer extension to fold inward, so that the outer extension is adhered to the bag opening to complete the bag sealing operation.

[0031] With this structure, after the material completes the first bagging operation in the first bagging mechanism, the material that has been bagged once can be sent to the second feeding platform 10 of the second bagging mechanism, so that the material can be directly bagged a second time in the second bagging mechanism. This realizes continuous automated packaging of bags within bags, effectively improving the bagging quality and efficiency of the packaging bags.
