[0043] The embodiments of the utility model will be described in detail below with reference to the drawings.

[0044] As Figures 1 to 16As shown, the compact packaging device of the embodiment comprises a main conveying device 1, which comprises a conveying frame 11 and a conveying belt 12 connected to the conveying frame 11, and is sequentially provided with a bag feeding station 101, a bag opening and filling station 102 and a bag arranging and sealing station 103 along the conveying direction of the main conveying device 1. The bag feeding station 101 is provided with an automatic bag feeding device 2 for feeding the packaging bags 800 to the main conveying device 1 one by one. The bag opening and filling station 102 is provided with an automatic bag opening device 3 for opening the packaging bags 800 conveyed on the main conveying device 1 and an automatic bag filling device 4 for filling the products into the opened packaging bags 800. The bag arranging and sealing station 103 is provided with an automatic bag arranging and sealing device 5 for automatically sealing the packaging bags 800 after being arranged neatly. The packaging bags 800 are fed to the main conveying device 1 one by one by the automatic bag feeding device, and are sequentially conveyed through the bag opening and filling station and the bag arranging and sealing station. When the packaging bags reach the bag opening and filling station, the automatic bag opening device opens the packaging bags, and then the automatic bag filling device pushes the products conveyed by the product conveying line into the opened packaging bags 800. When the packaging bags reach the bag arranging and sealing station, the automatic bag arranging and sealing device seals the packaging bags after being arranged neatly, so that the automatic packaging is completed. The device has the advantages of simple and compact structure, small floor space, high work efficiency and low failure rate.

[0045] The automatic bag feeding device is used for feeding the neatly stacked packaging bags (the embodiment adopts the organ bag with one side sealed and one side not sealed) to the main conveying line one by one.

[0046] As Figures 3-5As shown, the automatic bag feeding device 2 comprises a bag feeding frame 21, a magazine 22 for temporarily storing the packaging bags 800, and a single bag taking mechanism 23 for taking and transferring the packaging bags 800 from the magazine 22 one by one to the main conveying device 1. The magazine 22 is arranged on the bag feeding frame 21 and located directly above the main conveying device 1. The bottom of the magazine 22 is provided with an output opening through which the packaging bags 800 can pass. The single bag taking mechanism 23 comprises a lifting seat 231, a turnover frame 232, and a lifting drive assembly 233. The lifting seat 231 is slidingly connected to the bag feeding frame 21. The lifting drive assembly 233 is arranged on the bag feeding frame 21 to drive the lifting seat 231 to move up and down relative to the bag feeding frame 21. The lifting seat 231 is rotatably connected to a turnover shaft 234. The turnover frame 232 is connected to the turnover shaft 234. The turnover frame 232 is provided with a first suction assembly 235 (suction cups in this embodiment) for suctioning the packaging bags 800. The turnover shaft 234 and the bag feeding frame 21 are provided with a reversing guide mechanism 236 for guiding the turnover shaft 234 to rotate to drive the first suction assembly 235 on the turnover frame 232 to turn from an upward state to a downward state when the lifting seat 231 moves downward from top to bottom. In use, the neatly stacked packaging bags are placed in the magazine. At the beginning, the first suction assembly on the turnover frame is upward and can suction the packaging bag at the bottom of the magazine. Then the lifting drive assembly drives the lifting seat to move downward (also driving the turnover frame to move downward). During the downward movement of the lifting seat, the turnover shaft 234 is guided by the reversing guide mechanism 236 to rotate by 180° (the first suction assembly 235 on the turnover frame 232 also rotates together with the packaging bag), so that when the lifting seat descends to the lowest position, the first suction assembly 235 is downward. At this time, the first suction assembly 235 is released, and the packaging bag can fall into the main conveying device. The cycle is repeated. In addition, only one power (the lifting drive assembly 233) is needed to drive the lifting and turnover of the turnover frame, which has the advantages of simple structure, low cost, and easy maintenance.

[0047] In this embodiment, the reversing guide mechanism 236 comprises a guide block 2361 and a handle 2362, the handle 2362 is connected to the turnover shaft 234 and can rotate with the turnover shaft 234, the handle 2362 is provided with a first sliding groove 23620, the guide block 2361 is pivoted to the bag conveying frame 21, the guide block 2361 is provided with a second sliding groove 23610 in which the turnover shaft 234 can smoothly slide, in order to make the turnover shaft 234 smoothly slide in the second sliding groove 23610, a rotating ring (similar to a bearing) is sleeved on the position of the turnover shaft 234 which contacts with the second sliding groove 23610; the second sliding groove 23610 comprises an upper vertical section 236101, an arc-shaped guide section 236102 and a lower vertical section 236103 which are sequentially communicated, the guide block 2361 is provided with a sliding column 23611 which can slide in the first sliding groove 23620; when the turnover shaft 234 moves from top to bottom with the lifting seat 231, the turnover shaft 234 can slide along the upper vertical section 236101, the arc-shaped guide section 236102 and the lower vertical section 236103, and when the turnover shaft 234 moves to the arc-shaped guide section 236102, the turnover shaft 234 can drive the guide block 2361 to swing relative to the bag conveying frame 21, at the same time, the sliding column 23611 and the first sliding groove 23620 on the handle 2362 jointly act to drive the turnover shaft 234 to rotate.

[0048] Now, the drawings will be described in conjunction with the Figures 3-5 The working principle of the reversing guide mechanism 236 will be described.

[0049] Firstly, the lifting seat can only move up and down in the vertical direction (cannot move left and right), therefore, the turnover shaft can also only move up and down in the vertical direction, and the turnover shaft and the turnover frame can rotate relative to the lifting seat;

[0050] Secondly, because the turnover shaft 234 can smoothly slide in the second sliding groove 23610 on the guide block 2361, and the guide block 2361 is pivoted to the bag conveying frame 21, therefore, in the process of the turnover shaft moving downward, the guide block 2361 can swing relative to the bag conveying frame;

[0051] Thirdly, the handle 2362 is connected to the turnover shaft 234 and can rotate with the turnover shaft 234, the handle 2362 is provided with the first sliding groove 23620, and the guide block 2361 is provided with the sliding column 23611 which can slide in the first sliding groove 23620, therefore, when the turnover shaft moves downward and passes through the arc-shaped guide section 236102, the sliding column 23611 and the first sliding groove 23620 on the handle 2362 jointly act to drive the handle 2362 to reverse, and then drive the turnover shaft 234 to rotate, thereby driving the first adsorption assembly 235 on the turnover frame 232 to reverse from the upward state to the downward state.

[0052] In order to prevent the guide block 2361 from swinging relative to the bag feeding frame during the initial and final downward movements of the flipping shaft, in this embodiment, the center lines of the upper vertical section 236101, the lower vertical section 236103, and the sliding column 23611 are collinear, and the center line of the first slide groove 23620 intersects the axis of the flipping shaft 234.

A storage space 2202 for temporarily storing packaging bags 800 is provided between the left baffle 221, right baffle 222, front stop 223, and rear stop 224. The bottom of the storage space 2202 has a support edge 225 for supporting the edges of the packaging bags 800. The support edge 225 supports the edges of the packaging bags 800. Because the packaging bags are made of deformable plastic film, when the first adsorption component moves downwards, the packaging bags located at the bottom of the storage space 2202 can be pulled off from the support edge 225.

[0054] In this embodiment, the lifting drive assembly 233 includes: a first rack 2331, a first gear 2332, a second rack 2333, and a second gear 2334. Both the first rack 2331 and the second rack 2333 are connected to the lifting seat 231. The first gear 2332 is rotatably connected to the bag feeding frame 21 and meshes with both the first rack 2331 and the second gear 2334. The second gear 2334 is rotatably connected to the bag feeding frame 21 and meshes with both the second rack 2333 and the first gear 2332. The lifting seat 231 is equipped with a lifting motor 2335 that drives the second rack 2333 to rotate, thereby raising and lowering the lifting seat 231. This design allows for more stable lifting of the lifting seat.
