It should be noted that the guide frame 1 slides inside the frame of the packing machine via a cylinder or an internal lifting mechanism, as described in the patent title: A Fully Automatic Horizontal Packing Machine (Patent Publication No.: CN112937976A). The guide frame 1 is internally rotatably equipped with several guide groups, and each of the guide groups and the guide frame 1 is provided with an adjustment mechanism, the adjustment mechanism including: The guide assembly includes four guide vanes 2, which are arranged perpendicularly to each other; a plurality of drive rods 31 are slidably connected inside the guide frame 1, and the drive rods 31 pass through the inside of the guide vanes 2; a rotating assembly for driving the guide vanes 2 to rotate is provided between the drive rods 31 and the guide vanes 2. Each drive rod 31 has an adjusting ring 32 slidably connected to its surface. The adjusting ring 32 has a drive shaft and a transverse shaft fixedly connected to its surface. A drive rod 33 is slidably connected between adjacent drive shafts. An adjusting rod 34 is rotatably connected inside the guide frame 1. The adjusting rod 34 is threadedly connected to the drive rod 33. The adjusting rod 34 is a two-way lead screw; The guide frame 1 has two transverse rods 35 rotatably connected inside, the ends of the two transverse rods 35 are rotatably connected, and the transverse rods 35 are slidably connected to the transverse shaft; In summary, the automatic packing device for liquid milk bottles provided by this invention includes several guide vanes 2 rotatably disposed inside a guide frame 1. The four guide vanes 2 are arranged perpendicularly to each other. The rotation of the guide vanes 2 can change the distance between adjacent guide vanes 2, and the spatial dimension between the four guide vanes 2 can also be changed. Therefore, the space between the guide vanes 2 can be adjusted according to the size of the bottled milk to be packed. The guide vanes 2 can be rotated by a drive rod 31, and a sliding adjustment ring 32 is provided on the surface of the drive rod 31. The adjustment ring 32 is provided with a drive shaft and a transverse shaft. The distance between the drive shaft and the transverse shaft can be adjusted by adjusting the position of the adjustment rod 34 and the transverse rod 35, so that the distance between the guide vanes 2 on opposite sides can be changed. The distance can be adjusted according to the quantity or size of the bottled milk packed in a single pack, ensuring that the four guide vanes 2 can be combined with a single row or a single bottled milk label to assist in the packing and positioning of the bottled milk. In some specific embodiments, the rotating assembly includes a helical shaft 41 fixedly disposed on the surface of the drive rod 31, and a helical groove 42 is provided inside the guide vane 2. The helical shaft 41 is adapted to the helical groove 42. When the drive rod 31 slides, the guide vane 2 can be driven to rotate through the helical shaft 41 that is adapted to the surface of the drive rod 31 and the helical groove 42 inside the guide vane 2. In some specific embodiments, the drive rod 31 is made of carbon fiber composite material or glass fiber composite material, which has toughness and high tensile strength, and can support the position of the guide vane 2; the drive rod 31 includes a drive shaft and a drive column, the drive shaft is fixedly connected to the drive column, the surface of the drive column is provided with a sliding groove 43, the drive shaft is adapted to the sliding groove 43, and a connecting spring 44 is fixedly connected between the drive shaft and the adjacent drive column; the drive rod 31 is divided into a drive shaft and a drive column with fixed ends, and a sliding groove 43 adapted to the drive shaft is opened inside the drive column. The position of the drive column of the drive rod 31 can slide into the sliding groove 43 of the adjacent drive rod 31, and a connecting spring 44 is provided between the two to limit the position between the adjacent drive shafts; In a further embodiment, a plurality of drive teeth 45 are fixedly connected to the surface of the drive column, and the plurality of drive teeth 45 are arranged at intervals. The edges of the drive column and the drive teeth 45 are arc-shaped. A drive gear 46 is rotatably connected inside the guide frame 1, and the drive gear 46 meshes with the drive teeth 45. A limiting component for limiting the angle is provided between the drive gear 46 and the guide frame 1. By setting the edges of the drive column and the drive teeth 45 to be arc-shaped, the shape of the drive teeth 45 is limited, ensuring that the drive teeth 45 can slide inside the guide vane 2 and avoid interference. At the same time, a drive gear 46 is provided. Rotating the gear can change the position of the drive teeth 45, thereby driving the drive column to slide and causing the guide vane 2 to rotate. In a further embodiment, each of the drive gears 46 is fixedly connected to a synchronous pulley 51, and a synchronous belt 52 is driven between adjacent synchronous pulleys 51; the internal clearance of several guide groups can be quickly controlled by the synchronous pulleys 51 and the synchronous belt 52, and the rotation of all drive gears 46 can be quickly restricted by a single limiting component, which is convenient for operation; In some specific implementations, a drive column 53 is fixedly connected to the surface of the drive rod 33, and a protruding column is protruding from the surface of the drive gear 46. The protruding column is rotatably disposed inside the drive column 53. The protruding column and the drive column 53 limit the position of the drive gear 46 and the position of the drive rod 33. When the drive rod 33 slides, it can simultaneously cause the drive column 53 to slide, ensuring that the drive gear 46 does not disengage from the drive gear 45. In some specific implementations, each end of the transverse rod 35 is fixedly connected to a synchronous shaft 54. The two synchronous shafts 54 are symmetrically arranged and slidably disposed on the surface of the transverse shaft. Each set of guide vanes 2 is provided with four drive rods 31, which in turn provide four adjusting rings 32. Each adjusting ring 32 is provided with a transverse shaft. Two transverse shafts are connected to the rotating transverse rod 35, and the remaining transverse shafts are connected through the synchronous shafts 54 at the ends of the transverse rod 35. Thus, when the transverse rod 35 rotates, it can cause all four transverse shafts to change position, which is convenient for control. In some specific implementations, a rotating column 61 is rotatably connected to the end of the transverse rod 35. A synchronizing rod 62 is threadedly connected inside the rotating column 61. One end of the synchronizing rod 62 is rotatably connected to the driving rod 33, and the other end of the synchronizing rod 62 passes through and extends to the surface of the guide frame 1. The angle of the synchronizing rod 62 on the surface of the guide frame 1 is limited by a limiting component. The rotating synchronizing rod 62 is provided inside the driving rod 33, and the synchronizing rod 62 is threadedly connected to the rotating column 61. Rotating the synchronizing rod 62 can change the distance between the rotating column 61 and the driving rod 33, so that the position of the transverse rod 35 will not be affected when the driving rod 33 moves. In a further embodiment, the limiting component includes a plurality of triangular grooves 71 formed on the surface of the synchronizing rod 62 or the driving gear 46, the plurality of triangular grooves 71 being arranged in a circular array, a triangular rod 72 being slidably connected inside the guide frame 1, the triangular rod 72 being adapted to the triangular grooves 71; a limiting spring 73 being fixedly connected between the triangular rod 72 and the guide frame 1. In a further embodiment, an operating rod is fixedly connected to the surface of the triangular rod 72, the operating rod extends through and to the surface of the guide frame 1, and the limiting spring 73 is sleeved on the surface of the operating rod; In some specific implementations, a limiting rod 81 is slidably connected to the end of the adjusting rod 34, and a plurality of limiting grooves 82 are formed on the surface of the guide frame 1. The limiting grooves 82 are adapted to the limiting rods 81, and the plurality of limiting grooves 82 are arranged in a circular array with the limiting rods 81 as the center, and adjacent limiting grooves 82 are connected; a limiting spring 83 is fixedly connected between the limiting rods 81 and the adjusting rod 34. In some specific implementations, a movable shaft is fixedly connected to the surfaces of the drive shaft and the transverse shaft. The cross-section of the movable shaft is T-shaped. Movable grooves are formed on the surfaces of the drive rod 33 and the transverse rod 35. The movable shaft is adapted to the movable grooves. Working principle of the invention: When the size of the bottled liquid milk in the box changes, firstly, the limiting rod 81 can be pulled to disengage it from the limiting groove 82. Then, the adjusting rod 34 can be rotated, changing the position of the driving rod 33. This change in the position of the driving rod 33 causes the driving shaft to slide, thus changing the distance between the driving shafts. This alters the distance between the two guide vanes 2. Once the distance is appropriate, the limiting rod 81 can be released. Under the action of the limiting spring 83, the limiting rod 81 inserts into the limiting groove 82, restricting the rotation of the adjusting rod 34. Next, the triangular rod 72 can be pulled to disengage it from the triangular groove 71 on the surface of the synchronizing rod 62. Rotating the synchronizing rod 62 changes the position of the rotating column 61, causing the end of the transverse rod 35 to change position, and the transverse rod 35 rotates as a whole. This causes a change in the distance between the transverse axes, which in turn changes the distance between the other two guide vanes 2. Once the distance is appropriate, the triangular rod 72 is released, and under the action of the limiting spring 73, the triangular rod 72 is inserted into the triangular groove 71. Finally, the angle of the guide vane 2 can be changed, pulling the triangular rod 72, causing it to disengage from the triangular groove 71 on the surface of the driving gear 46, rotating the driving gear 46, causing the driving teeth 45 to slide, and driving the driving rod 31 to slide. During the sliding process, the driving rod 31 passes through the spiral groove 42 and the spiral shaft 41, causing the guide vane 2 to rotate. When the surface of the guide vane 2 can fit with a single bottle or a single row of bottled liquid milk, the triangular rod 72 is released, and the triangular rod 72 is inserted into the triangular teeth on the surface of the driving gear 46 by the limiting spring 73.

[0022] The above-disclosed embodiments are merely a few specific examples of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
