Description

Technical Field

[0001] This utility model relates to a packaging machine, specifically a bag-holding device for an automatic aluminum-plastic cap packaging machine. Background Technology

[0002] After the aluminum-plastic caps are produced, they need to be bagged and sealed in a sterile and clean environment using plastic bags. Currently, bagging and sealing are generally done manually. Manual bagging and sealing are inefficient and make it difficult to ensure a sterile and clean environment on the production site, which cannot meet the needs of large-scale production.

[0003] Existing patent CN117944955A discloses a filling and sealing integrated machine and its filling and sealing method. This solution connects the bag-picking station, filling station, sealing station, and bag-placing station in series via a rotating bag-carrying device, enabling automatic packaging of aluminum-plastic caps. This solution includes a lifting platform for supporting the packaging bag. When the aluminum-plastic cap is fed into the packaging bag and when the bag's opening is sealed, the lifting platform supports the bottom of the bag. However, this structure only achieves lifting; the packaged aluminum-plastic caps need to be transported to the conveying station by the rotating bag-carrying device before output. This makes it difficult to replace the rotating bag-carrying mechanism and optimize the overall footprint of the packaging machine.

[0004] Therefore, there is an urgent need for a bag-carrying device that can simultaneously lift and support the bag and output the finished product packaging. Utility Model Content

[0005] The purpose of this utility model is to provide a bag-carrying device for an automatic aluminum-plastic cap packaging machine, so as to solve the problem that the lifting platform of the existing aluminum-plastic cap packaging machine cannot output finished product packaging.

[0006] This utility model is implemented as follows: an automatic aluminum-plastic cap packaging machine bag-holding device includes a lifting frame, a lifting mechanism, a tray, a lifting mechanism, and a swing mechanism. There are two lifting mechanisms, which are installed on the machine frame and located on both sides of the tray. Lifting frames are respectively provided on the two lifting mechanisms, and the two lifting frames are driven to move up and down synchronously by the two lifting mechanisms. A swing shaft is provided at the bottom of the tray, and the two ends of the swing shaft are rotatably connected to the two lifting frames respectively. The two swing mechanisms are respectively provided on both sides of the tray for driving the tray to rotate around the swing shaft. The lifting mechanism includes a lifting cylinder and a lifting plate. The lifting cylinder is provided on the lower surface of the tray, and the cylinder shaft of the lifting cylinder passes upward through the tray. The lifting plate is located on the upper surface of the tray and is connected to the cylinder shaft of the lifting cylinder.

[0007] As a further improvement of this utility model, upward-facing side baffles are provided on both sides of the tray.

[0008] As a further improvement of this utility model, an anti-tilt bar is provided at the rear of the tray, the anti-tilt bar is located above the tray, and a swing frame is provided at both ends of the anti-tilt bar. The middle part of the swing frame is hinged to the tray, and the front part of the swing frame extends downward through a through hole opened on the surface of the tray to the bottom of the tray. An anti-tilt telescopic cylinder is provided at the bottom of the tray, and the swing frame is driven to swing by the anti-tilt telescopic cylinder.

[0009] As a further improvement of this utility model, a connecting shaft is provided between the lower ends of the two swing frames, a support frame is provided on the lower surface of the tray, the cylinder body of the anti-tilt telescopic cylinder is hinged to the support frame, and the cylinder shaft of the anti-tilt telescopic cylinder is rotatably connected to the connecting shaft.

[0010] As a further improvement of this utility model, the lifting mechanism is a vertical electric slide table, and the lifting frame is connected to the slide table of the vertical electric slide table.

[0011] As a further improvement of this utility model, the swing mechanism is a telescopic cylinder, the lower end of which is hinged to the lower rear end of the lifting frame, and the upper end of which is hinged to the rear of the tray.

[0012] The pallet of this utility model can be driven to move up and down by a lifting mechanism. The pallet can lift the bottom of the packaging bag by raising it. After the packaging bag is filled and the bag opening is sealed, the pallet can carry the packaging bag down to reduce the height of the packaging bag. By rotating and tilting the pallet around the swing axis and lifting the lifting plate, the packaging bag with the aluminum-plastic cap is unloaded to the front of the pallet for output.

[0013] During the pallet descent, as the packaging bags are no longer restricted by other mechanisms, raising the anti-tipping bar at the rear of the pallet can prevent the packaging bags from tipping backward, thus ensuring the normal output of the packaging bags. Attached Figure Description

[0019] The specific embodiments of this utility model will now be described with reference to the accompanying drawings.

[0020] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., 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 the present invention 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 limiting the present invention.

[0021] like Figure 1 , Figure 2 As shown, the bag-carrying device of the automatic aluminum-plastic cap packaging machine of this utility model specifically includes a lifting frame 2, a lifting mechanism 1, a tray 3, a lifting mechanism, and a swinging mechanism 4.

[0022] The system comprises two lifting mechanisms 1, located on opposite sides of the tray 3 and fixedly mounted on the frame. Lifting frames 2 are mounted on each of the two lifting mechanisms 1, moving synchronously up and down as driven by the two lifting mechanisms 1. A swing shaft 7 is fixedly connected to the bottom of the tray 3, allowing the tray 3 to rotate around its axis. Both ends of the swing shaft 7 are rotatably connected to the two lifting frames 2; specifically, the ends of the swing shaft 7 are connected to the lifting frames 2 via bearings. Swing mechanisms 4 are located on both sides of the tray 3, driving the tray 3 to rotate around the swing shaft 7.

[0023] A lifting mechanism is installed in the middle of pallet 3. The lifting mechanism includes a lifting cylinder 5 and a lifting plate 6. The lifting cylinder 5 is fixedly installed on the lower surface of pallet 3, and its cylinder axis passes upward through pallet 3. The lifting plate 6 is located on the upper surface of pallet 3 and is connected to the cylinder axis of the lifting cylinder 5. The extension and retraction of the lifting cylinder 5 can raise the lifting plate 6 above the upper surface of pallet 3 or lower it to contact the upper surface of pallet 3. The lifting plate 6 is relatively thin. When the lifting plate 6 contacts the upper surface of pallet 3, it is approximately flush with the upper surface of pallet 3 and will not have a significant impact on the packaging bags placed on pallet 3.

[0024] An upward-facing side baffle 3-1 is provided on both sides of the pallet 3. The side baffle 3-1 can restrict the packaging bags placed on the pallet 3 from moving to both sides. On the other hand, the side baffle 3-1 can be used as a connecting part to connect with the swing mechanism 4, the swing frame 9, etc.

[0025] An anti-tilt bar 8 is provided at the rear of the tray 3. The anti-tilt bar 8 is located above the tray 3. The length of the anti-tilt bar 8 is slightly less than the distance between the two side baffles 3-1 of the tray 3, and the anti-tilt bar 8 is located between the two side baffles 3-1. A swing frame 9 is provided at both ends of the anti-tilt bar 8. The two swing frames 9 are also located between the two side baffles 3-1. The middle part of the swing frame 9 is hinged to the side baffle 3-1 of the tray 3. The front part of the swing frame 9 extends downward through the through hole opened on the surface of the tray 3 to the bottom of the tray 3. An anti-tilt telescopic cylinder 11 is provided at the bottom of the tray 3. The anti-tilt telescopic cylinder 11 drives the swing frame 9 to swing around its hinge axis with the side baffle 3-1, thereby raising or lowering the anti-tilt bar 8 at the rear of the tray 3.

[0026] Specifically, a connecting shaft 12 is provided between the lower ends of the two swing frames 9, and the connecting shaft 12 is located below the tray 3. A support frame 10 is provided on the lower surface of the tray 3. The cylinder body of the anti-tilt telescopic cylinder 11 is hinged to the support frame 10, and the cylinder shaft of the anti-tilt telescopic cylinder 11 is rotatably connected to the connecting shaft 12. Since the lifting cylinder 5 is located in the middle of the lower part of the tray 3, the anti-tilt telescopic cylinder 11 can only be located on one side of the lifting cylinder 5. The support frame 10 consists of two support plates perpendicular to the lower surface of the tray 3. The support frame 10 is located on one side of the lifting cylinder 5, and the anti-tilt telescopic cylinder 11 is located between the two support plates. The anti-tilt telescopic cylinder 11 drives the movement of the connecting shaft 12 through telescopic movement, thereby synchronously driving the two swing frames 9 at both ends of the connecting shaft 12 to rotate around the hinge axis that is hinged to the side baffle 3-1 of the tray 3.

[0027] Among them, the lifting mechanism 1 is a vertical electric slide, and the lifting frame 2 is connected to the slide of the vertical electric slide.

[0028] The swing mechanism 4 is a telescopic cylinder. The lower end of the telescopic cylinder is hinged to the lower rear end of the lifting frame 2, and the upper end of the telescopic cylinder is hinged to the rear of the tray 3.

[0029] The working process of this utility model is as follows: When filling the packaging bag, the lifting mechanism 1 drives the tray 3 to rise, and the tray 3 supports the bottom of the packaging bag and bears the weight of the material inside the packaging bag. After filling is completed, the upper part of the packaging bag disengages from the upper bag clamping device, and the lifting mechanism 1 drives the tray 3 to descend to the lower limit position. During the descent, the anti-tilt bar 8 at the rear of the tray 3 is raised to prevent the packaging bag from tipping backward. After the tray 3 descends to the lower limit position, the tray 3 tilts forward around the swing shaft 7, and the lifting plate 6 is raised upward, causing the packaging bag to tilt forward and be output. Lowering the packaging bag to the lowest position before outputting it can minimize the height difference when the packaging bag falls, thereby avoiding damage and deformation of the aluminum-plastic cap inside the packaging bag.
