Description

Technical Field

[0001] This utility model relates to the field of material packaging technology, specifically to a zipper opening device for packaging bags. Background Technology

[0002] In industries such as food and pharmaceuticals, finished products are mostly packaged in bags. With constantly changing market demands, more and more bags are adopting zippered designs, which increases the difficulty of filling finished products. In existing automatic packaging machines, the zipper must be opened first before subsequent steps such as opening, filling, and sealing can be completed.

[0003] When opening a zipper bag, a typical packaging machine requires pulling the zipper open on both sides to open the top for easy filling. However, since zipper bags have a certain suction force on both sides after closing, a certain amount of pulling force is needed to open them. Most packaging machines use suction cups on both sides of the zipper bag to adhere to it before pulling the zipper open. While this method is efficient, in dry environments and after prolonged use, the suction effect of the suction cups deteriorates, making it difficult to fully adhere to the bag surface. This results in poor adhesion and affects the overall opening efficiency and quality. Utility Model Content

[0004] The purpose of this invention is to provide a zipper opening device for packaging bags, which aims to solve the problems of low opening efficiency and poor opening effect of existing zipper opening devices for packaging bags.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] The suction bag mechanism includes a suction bag linkage component and two suction bag components. The two suction bag components are both mounted on the frame and connected through the suction bag linkage component. The driving mechanism is connected to the suction bag linkage component to drive the two suction bag components to move closer to or further away from each other.

[0010] The bag opening mechanism includes a bag supporting assembly and two clamping assemblies. The bag supporting assembly is disposed on the frame and is connected to the two clamping assemblies to drive the two clamping assemblies to move closer to or further away from each other.

Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0030] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature.

[0031] The following is combined with Figures 1 to 4 This invention describes a zipper-opening device for packaging bags.

[0032] like Figures 1 to 4 As shown, this utility model provides a zipper opening device for packaging bags, including a frame 1, a drive mechanism 2, a bag suction mechanism 3, and a bag opening mechanism 4. The drive mechanism 2 is located on the frame 1. The bag suction mechanism 3 includes a bag suction linkage component 31 and two bag suction components 32. Both bag suction components 32 are located on the frame 1 and are connected through the bag suction linkage component 31. The drive mechanism 2 is connected to the bag suction linkage component 31 to drive the two bag suction components 32 to move closer to or further away from each other. The bag opening mechanism 4 includes a bag support component 41 and two clamping components 42. The bag support component 41 is located on the frame 1 and is connected to the two clamping components 42 to drive the two clamping components 42 to move closer to or further away from each other.

[0033] In the zipper-opening device for packaging bags provided by this utility model, the frame 1 serves as the foundation of the overall structure, providing stable support. The drive mechanism 2 is responsible for providing power so that the entire device can work normally. The bag suction mechanism 3 includes two bag suction components 32, which are connected by a bag suction linkage component 31. They can move closer or further apart simultaneously under the drive of the drive mechanism 2, thereby achieving the suction and placement of the packaging bag. The bag opening mechanism 4 includes a bag supporting component 41 and two clamping components 42. The clamping components 42 are used to clamp the edge part of the packaging bag. The bag supporting component 41 can drive the clamping components 42 to move closer or further apart, thereby opening the packaging bag and clamping it in a suitable position. In this way, in addition to adsorbing the surface of the packaging bag, it can also clamp the edge part of the packaging bag, resulting in a better clamping effect, more stable opening of the bag opening, better opening effect, and higher opening efficiency.

[0034] In some embodiments, the suction bag assembly 32 includes a suction bag swing plate 321, a suction bag rotating shaft 322, a suction bag pad 323, and a vacuum suction cup 324. The suction bag swing plate 321 is rotatably connected to the frame 1 via the suction bag rotating shaft 322, and the suction bag pad 323 and the vacuum suction cup 324 are both disposed on the suction bag swing plate 321.

[0035] Specifically, the suction pads 323 in the two suction bag assemblies 32 are respectively attached to the two sides of the packaging bag to keep the packaging bag flat. The vacuum suction cup 324 is used to adsorb the packaging bag. The driving mechanism 2 drives the two suction bag swing plates 321 to move away simultaneously, thereby completing the bag opening work. The bag opening efficiency is high and the bag opening effect is good.

[0036] In some embodiments, the drive mechanism 2 includes a drive motor 21, and the suction bag linkage assembly 31 includes a first suction bag connecting rod 311, a second suction bag connecting rod 312, a suction bag linkage seat 313, and two suction bag linkage gears 314. The two suction bag rotating shafts 322 in the two suction bag assemblies 32 are respectively connected to the two suction bag linkage gears 314, and the two suction bag linkage gears 314 mesh with each other. The suction bag linkage seat 313 is disposed on one of the suction bag swing plates 321. One end of the first suction bag connecting rod 311 is connected to the drive motor 21, and the other end of the first suction bag connecting rod 311 is rotatably connected to one end of the second suction bag connecting rod 312. The other end of the second suction bag connecting rod 312 is rotatably connected to the suction bag linkage seat 313.

[0037] Specifically, the drive motor 21 drives the first suction bag connecting rod 311 to rotate, and the first suction bag connecting rod 311 drives the second suction bag connecting rod 312 to rotate, thereby driving one of the suction bag swing plates 321 to rotate around the suction bag rotating shaft 322, and then driving one of the suction bag linkage gears 314 to rotate, which in turn drives the other suction bag linkage gear 314 to rotate, and then drives the other suction bag swing plate 321 to rotate, thereby completing the mutual separation of the two suction bag swing plates 321, and thus completing the bag opening work. The bag opening efficiency is high and the bag opening effect is good.

[0038] In some embodiments, the suction bag pad 323 is provided with a silicone pad, which can reduce damage to the packaging bag.

[0039] In some embodiments, the bag-supporting assembly 41 includes a lifting cylinder 411, a bag-opening linkage cylinder 412, a bag-opening linkage plate 413, and two inner bag-opening claws 414. The clamping assembly 42 includes outer bag-opening claws 421 and clamping cylinders 422. The lifting cylinder 411 is mounted on the frame 1 and is connected to the bag-opening linkage cylinder 412. The bag-opening linkage cylinder 412 is connected to the bag-opening linkage plate 413. The two clamping cylinders 422 are both mounted on the bag-opening linkage plate 413 and are respectively connected to the two outer bag-opening claws 421. The two inner bag-opening claws 414 are both connected to the bag-opening linkage plate 413.

[0040] Specifically, the lifting cylinder 411 drives the bag-opening linkage cylinder 412, the bag-opening linkage plate 413, the two inner bag-opening claws 414, and the two clamping components 42 to descend, so that the two inner bag-opening claws 414 can enter the gap of the packaging bag opening. Then, the clamping cylinder 422 drives the outer bag-opening claw 421 to rotate inward. The outer bag-opening claw 421 and the inner bag-opening claws 414 jointly clamp the edge of the packaging bag opening. The clamping cylinder 422 is connected to the outer bag-opening claw 421 through a connecting rod structure. The bag-opening linkage cylinder 412 is connected to the inner bag-opening claw 414 through a connecting rod structure. The outer bag-opening claw 421 is rotatably connected to the bag-opening linkage plate 413. The piston rod of the bag-opening linkage cylinder 412 moves downward, driving the inner bag-opening claw 414 to move outward through the connecting rod structure, thereby opening the bag opening. The bag opening efficiency is high and the bag opening effect is good.

[0041] In some embodiments, both clamping cylinders 422 are lever clamping cylinders 422, which provide better clamping effect.

[0042] In some embodiments, both inner claws 414 of the bag opening mechanism are provided with anti-slip textures for better gripping effect.

[0043] In some embodiments, both external claws 421 are provided with silicone pads. The softness of the silicone pads can reduce damage to the surface of the packaging bag and protect the packaging bag from scratches or deformation.

[0044] In some embodiments, the drive mechanism 2 further includes a limiting shaft 22, a limiting link structure 23, and a limiting cylinder 24. The limiting shaft 22 is rotatably connected to the frame 1 and is a hollow structure. The limiting shaft 22 is sleeved on the output shaft of the drive motor 21 and has a limiting hole 25. One end of the first suction bag link 311 is connected to the drive motor 21, and the other end of the first suction bag link 311 passes through the limiting hole 25 and is rotatably connected to one end of the second suction bag link 312. The limiting cylinder 24 is connected to the limiting shaft 22 through the limiting link structure 23. The limiting cylinder 24 drives the limiting shaft 22 to rotate through the limiting link structure 23, thereby fixing the position of the limiting hole 25 and limiting the range of the limiting hole 25, i.e., the rotation amplitude of the first suction bag link 311, thereby controlling the rotation amplitude of the suction bag swing plate 321, thus adapting to different sizes of packaging bags and having better adaptability.

[0045] In some embodiments, the limiting cylinder 24 is a self-locking cylinder that can limit the rotation position of the limiting shaft 22, thereby fixing the position of the limiting hole 25, and further limiting the limiting range of the limiting hole 25, that is, the rotation amplitude of the first suction bag connecting rod 311, thereby controlling the rotation amplitude of the suction bag swing plate 321, so as to adapt to different sizes of packaging bags and have better adaptability.

[0046] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
