Description

Technical Field

[0001] This utility model relates to the field of packaging machine technology, and more specifically, to a packaging machine for accessories. Background Technology

[0002] In the packaging of multi-component products, such as screws, nuts, connectors, and small hardware parts, the packaging method is usually manual or semi-automated. Operators need to manually place the bags, manually assist in opening the bags and putting multiple required components into the bags, and then seal the bags with a heat sealing machine. This method is not only labor-intensive, but also relies on manual coordination between each process, which easily leads to low packaging efficiency and poor product consistency.

[0003] Consequently, mechanical suction bag and sealing operations have been adopted to achieve more automated packaging. However, the current suction bag picking and pulling operations cannot efficiently transfer items, leading to deviations during the transfer process, which affects the accuracy of subsequent bagging and heat sealing. Furthermore, the bagging and heat sealing components are scattered and poorly coordinated, with each component unable to work together seamlessly, greatly impacting the production rhythm.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.

[0021] Example

[0022] Combination Figures 1 to 6 This embodiment provides a packaging machine for accessories, including a machine housing 1. The machine housing 1 has a hopper 2 in the upper feeding area and a bag support assembly 3 in the discharging area connected to the feeding area.

[0023] The machine housing 1 is equipped with a bag feeding assembly 4, a bag suction assembly 5, a transfer assembly 6, a bag pulling assembly 7, and a heat sealing assembly 8. The transfer assembly 6 moves freely laterally, reciprocating between the bag suction assembly 5 and the bag supporting assembly 3. The bag suction assembly 5 is used to suction and grasp the packaging bag provided by the bag feeding assembly 4, and further move the grasped packaging bag so that it can be captured by the transfer assembly 6. The transfer assembly 6 is adapted to transfer the packaging bag to face the bag pulling assembly 7, and after the two cooperate to pull open the packaging bag, it is used to align the opening of the packaging bag with the bag supporting assembly 3, thereby uniformly loading multiple accessories fed into the hopper 2 into the packaging bag. The heat sealing assembly 8 is used to heat seal the opening of the packaging bag. An outlet chamber 9 is provided at the bottom of the machine housing 1. The transfer assembly 6 and the bag pulling assembly 7 release the packaging bag simultaneously to output the bagged accessories along the outlet chamber 9.

[0024] In the aforementioned packaging machine for accessories, the suction bag assembly 5 automatically picks up packaging bags from the bag supply assembly 4 and transfers them to the transfer assembly 6 for relay transfer. This achieves continuous bag picking and opening without manual intervention, significantly improving production automation. The transfer assembly 6, capable of lateral reciprocating motion, creates an efficient transmission path between the suction bag station and the bag support station, ensuring the packaging bags maintain stable posture and precise position during transfer, preventing inaccurate filling due to bag offset. The bag pulling assembly 7 works in conjunction with the transfer assembly 6 to simultaneously open the bag opening. Combined with the hopper 2 and bag support assembly 3 located above, multiple accessories can be quickly and accurately placed into the packaging bag, improving bagging efficiency and production cycle. Subsequently, the heat sealing assembly 8 directly heat-seals the bag opening containing the accessories. Finally, the transfer assembly 6 and bag pulling assembly 7 simultaneously release the packaging bag, causing the sealed bag to automatically fall and be output, achieving automatic bag output and collection for subsequent boxing or conveying.

[0025] like Figures 2 to 5In this embodiment, the bag feeding assembly 4 and the bag suction assembly 5 are respectively arranged on one side of the machine housing 1, and the bag pulling assembly 7 and the heat sealing assembly 8 are respectively arranged on the other side of the machine housing 1. By concentrating the preceding processes such as bag picking and suction on one side of the machine housing 1, and the subsequent processes such as bag pulling and heat sealing on the other side, the transmission path of the packaging bag within the machine housing 1 extends in a single direction, reducing the turning and crossing of the packaging bag during transmission, and improving the smoothness of transmission and the coordination of the mechanism. Furthermore, with the components arranged in separate sections on both sides, the driving strokes of each structure do not interfere with each other, effectively avoiding the overlap of the bag suction and sealing processes, reducing mechanical conflict and the risk of bag jamming, thereby improving the overall operational stability of the machine.

[0026] Furthermore, the bag-supporting assembly 3 is located on the same side as the bag-pulling assembly 7 and the heat-sealing assembly 8, and is centrally positioned above the heat-sealing assembly 8. This ensures that the packaging bag is directly below the bag-supporting station after the bag opening is completed, avoiding multiple lateral transfers of the packaging bag within the machine housing 1, simplifying the overall transport route, and improving the continuity of equipment operation. Clearly, the centrally positioned bag-supporting assembly 3 above the heat-sealing assembly 8 places the bag-filling station directly below the hopper 2, providing stable support for the packaging bag after the bag opening is fully open. This ensures that accessories are accurately placed into the bag when falling from the hopper 2, preventing scattering or displacement, and improving filling accuracy.

[0027] In this embodiment, the bag-supporting assembly 3 includes an opening / closing spout 10 that can extend into the packaging bag. The transferring assembly 6 correspondingly grasps the packaging bag and transfers it to a position opposite to the bag-pulling assembly 7. The bag-pulling assembly 7 approaches and attracts the packaging bag, then resets to open the bag opening. The opening / closing spout 10 is used to open the packaging bag after it is pulled open, connecting the infeed area and the discharge area. When closed, the opening / closing spout 10 temporarily seals the infeed and discharge areas, serving as a foolproof protection mechanism. It should be noted that the opening / closing spout 10 specifically adopts an existing hinge structure, similar to a scissor-style opening and closing mechanism.

[0028] In this embodiment, the bag supply assembly 4 includes a stacking platform 11 for stacking multiple packaging bags, and the bag suction assembly 5 includes a rotating shaft 12 disposed directly above the stacking platform 11, a pusher 13 disposed on the rotating shaft 12, and a first suction cup 14 disposed on the pusher 13. The rotating shaft 12 has a first rotational state in which the first suction cup 14 is rotated to suction the packaging bags on the stacking platform 11, and a second rotational state in which the first suction cup 14 is rotated to face the transfer assembly 6.

[0029] In the above description, the stacking platform 11 is used to orderly stack multiple packaging bags, providing a stable base surface for the bag suction action. The bag suction assembly 5, through the first suction cup 14 mounted on the rotating shaft 12, can accurately suction the packaging bag on the top layer of the stacking platform 11 when rotating to the first rotation state, ensuring accurate bag retrieval each time and avoiding multiple or incorrect suction. Furthermore, the rotating shaft 12 drives the first suction cup 14 to switch between the first and second rotation states, allowing the packaging bag to be directly rotated to the direction of the transfer assembly 6 after suction is completed, eliminating the need for additional slide rails or handling mechanisms, shortening the transfer path, reducing the time from bag retrieval to bag delivery, and improving the equipment's operating cycle time. In addition, the pusher 13 is used to adjust the distance between the first suction cup 14 and the stacking platform 11 and the transfer assembly 6, facilitating position adjustment for gripping and transferring the packaging bag.

[0030] In this embodiment, the transfer component 6 includes a horizontally arranged guide rail 15 and a second suction cup 16 disposed on the guide rail 15. The second suction cup 16 is used to remove the packaging bag from the first suction cup 14 and move along the guide rail 15 until its second suction cup 16 faces the bag-pulling component 7. Obviously, by using the horizontally arranged guide rail 15, the second suction cup 16 can slide linearly along the guide rail 15, realizing the horizontal transfer of the packaging bag between the suction cup station and the bag-pulling station, avoiding the shaking and instability problems of traditional vertical flipping or complex swing arm mechanisms, and ensuring that the packaging bag is transferred smoothly and reliably. The second suction cup 16 directly removes the packaging bag from the first suction cup 14, realizing a seamless handover between the two suction cups. It can complete the adsorption and transfer before the bag is loosened, avoiding the packaging bag from slipping, curling or deforming, and ensuring the flatness of the bag throughout the entire transmission process.

[0031] In this embodiment, the bag-pulling assembly 7 includes a third suction cup 17 and a driving member 18 for switching the third suction cup 17 to be closer to or farther from the second suction cup 16. When closer, the third suction cup 17 and the second suction cup 16 jointly adhere to both sides of the packaging bag. When farther away, the third suction cup 17 and the second suction cup 16 cooperate to open the bag opening. The driving member 18 is the same mechanism as the aforementioned pushing member 13, used to directly push its respective suction cup. When the third suction cup 17 approaches the second suction cup 16 under the action of the driving member 18, it adheres to the opposite sides of the packaging bag. When the driving member 18 moves the third suction cup 17 away from the second suction cup 16, a relative tensile force is formed between the two suction cups, causing the bag opening to open automatically, replacing manual bag opening and significantly improving the automation level of packaging.

[0032] Preferably, the heat-sealing component 8 is disposed between the bag-supporting component 3 and the bag-suction component 5. The heat-sealing component 8 includes two opposing sealing members 19, one of which is positioned above the bag-suction component 5, and the other sealing component is horizontally positioned on the other side. The two sealing members 19 reciprocate between opening and closing to heat-seal the packaging bag. Specifically, after the bag-supporting component 3 is opened, multiple accessories from the feeding hopper 2 directly enter the opened packaging bag along the discharge area, and the opening and closing nozzle 10 of the bag-supporting component 3 pushes the bag opening outward so that the accessories can fall completely into the bag body. Subsequently, by distributing the heat-sealing component 8 between the bag-supporting component 3 and the bag-suction component 5, after the packaging bag is sucked open by the bag-pulling component 7 and supported and shaped by the bag-supporting component 3, a heat-sealing station can be reserved between them for sealing, thereby forming a continuous heat-sealing packaging process. The structure employs two opposing sealing components 19, with one sealing component 19 positioned above the suction bag assembly 5 and the other sealing component 19 horizontally positioned on the opposite side. The two components can reciprocate between opening and closing, achieving precise heat sealing of the packaging bag opening. This not only ensures accurate alignment of the sealing position and improves the reliability of the heat sealing, but also reduces the offset and wrinkling of the packaging bag during the transfer process.

[0033] It should be mentioned that each suction cup structure is specifically a negative pressure suction bag, which is an existing structure for picking up and putting down packaging bags. Furthermore, the sealing element 19 provided in the heat sealing assembly 8 is a commonly used sealing device that is widely used in the heat sealing field.

[0034] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions that fall within the scope of this utility model's concept are protected by this utility model.
