Description

Technical Field

[0001] The utility model relates to the field of packaging carton packaging, and more specifically, to a turnover packaging mechanism for packaging carton. Background Art

[0002] Packaging cartons are a common and important packaging material, mainly made of corrugated cardboard. They are relatively low in cost, have good cushioning properties, and can effectively protect the contents from impact and collision. At the same time, they are environmentally friendly and recyclable. Packaging cartons are easy to process and can be conveniently cut, folded, and printed to meet different packaging needs. They are light in weight and easy to handle and transport. However, they have limited waterproof properties and certain compressive strength limitations. They are widely used in many industries such as e-commerce, logistics, food, and electronic products, playing a key role in the storage, transportation, and sales of products.

[0003] During the packing process, some packaging cartons need to be specially reinforced on the bottom or specific sides of the cartons. When packing, the cartons need to be turned over for better operation. Generally, the cartons are turned over during the transmission process to move them to a suitable position. The above packaging work is performed manually or mechanically. The commonly used turning mechanism is to turn the packaging box along the way by driving the rotation of a cross frame. The length of each turning part of the cross frame cannot be adjusted. When encountering a large box, it is easy to fail to stably support the turning of the packaging box. However, if the length of the turning part is forcibly lengthened, it is useless in most cases and takes up a lot of space.

[0004] Therefore, in order to solve the above technical problems, the present application proposes a flipping and packaging mechanism for packaging cartons. Utility Model Content

[0005] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a flipping and packing mechanism for packaging cartons.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a packaging carton flipping and packaging mechanism, which is placed between two synchronously moving conveyor belts, the two conveyor belts are used to move the packaging boxes, and the packaging boxes are suspended in the air. When passing through the flipping and packaging mechanism, the packaging boxes are flipped. The flipping and packaging mechanism of the packaging carton includes a base, and a driving component for driving a cross-shaped shell to rotate is installed on the top of the base;

[0007] The cross-shaped shell includes a flip part and a central part, which are interconnected. Openings are arranged on the top surfaces of the four flip parts of the cross-shaped shell, and a length adjustment component is arranged in the central part to drive four inner blocks to extend from the four openings of the cross-shaped shell, thereby increasing the length of the four flip parts on the cross-shaped shell.

[0008] Preferably, the length adjustment assembly includes a rotating rod driven by a motor, a bevel gear A is fixedly connected to the middle part of the rotating rod, four bevel gears B whose axes are parallel to the flipping part are meshed and connected to the bevel gear A, a screw rod is fixedly connected to the back side of the bevel gear B, a rod sleeve is threadedly connected to the outer wall of the screw rod, the top of the rod sleeve is fixed to the inner block, a bearing A is sleeved on the bottommost part of the screw rod, and the screw rod is fixed in the inner ring of the bearing A, and the outer ring of the bearing A is fixed to the inner wall of the flipping part through a cross plate.

[0009] Preferably, a circular groove for the screw rod to pass through is opened inside the inner block, and the cross section of the inner block is the same as the internal cross section of the flip part. The circular groove is used to prevent the screw rod from being blocked by the inner block.

[0010] Preferably, a lifting assembly for adjusting the height of the driving assembly is provided on the base, and the height of the cross-shaped shell is adjusted to allow the cross-shaped shell to adapt to conveyor belt machines of different heights.

[0011] Preferably, the lifting assembly includes a rectangular rod welded to the top of the base, and a lifting plate fixed to the bottom of the driving assembly, the surface of the lifting plate is provided with through grooves for the rectangular rod to pass through, the side end of the rectangular rod is provided with a plurality of screw holes arranged in a vertical array and at equal distances, and the side end of the lifting plate is provided with a through hole.

[0012] Preferably, a limiting plate is fixedly connected between the tops of the rectangular rods, the cross section of the rectangular rods is the same as the cross section of the through slots, and the lifting plate can move up and down in a straight line along the rectangular rods.

[0013] Preferably, universal wheels with a locking function are installed around the bottom end of the base. After the mechanism is moved to a suitable position, the universal wheels are locked to fix the position of the mechanism.

[0014] Preferably, the other end of the rotating rod connected to the motor is rotatably connected to the inner side wall of the central portion via a bearing B. The rotation support of the bearing B can make the rotation of the rotating rod more stable.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] 1. The utility model places two synchronously running conveyor belt machines horizontally, leaving enough space between them for the packaging mechanism to be placed, and then moves the packaging mechanism between the two conveyor belt machines, and the driving component drives the rotation of the cross-shaped shell, so that the packaging box moved by the two conveyor belt machines is flipped 90 degrees by the flipping part on the cross-shaped shell. When the packaging box is too large and the flipping part on the cross-shaped shell cannot stably support the flipping of the packaging box due to insufficient length, the inner block can be driven to extend from the cross-shaped shell by the length adjustment component, so as to adjust the length of the flipping part to cope with this situation. Under normal circumstances, the inner block is retracted into the cross-shaped shell by the length adjustment component to reduce the space occupied, which is more practical, so as to solve the problem that when encountering a large box body in the background technology, it is easy to fail to stably support the flipping of the packaging box, but if the length of the flipping part is forcibly lengthened, it is useless in most cases and occupies a lot of space.

[0017] 2. In the utility model, since the cross section of the rectangular rod is the same as the cross section of the through groove, the lifting plate can move up and down linearly along the rectangular rod, so as to adjust the height of the driving assembly and the cross-shaped shell. After the height adjustment is completed, the height of the driving assembly and the cross-shaped shell can be fixed by passing the screw through the through hole on the lifting plate and then rotating it clockwise into the screw hole corresponding to the rectangular rod, and universal wheels with locking function are installed around the bottom of the base to facilitate the movement of the mechanism. In this way, it can be adjusted according to different conveyor belt machines and is convenient to move, so that the mechanism can be conveniently used with conveyor belt machines of different heights.

DETAILED DESCRIPTION

[0024] like Figure 1-4 As shown, the utility model provides a flipping and packing mechanism for packaging cartons, which is placed between two synchronously moving conveyor belts. The two conveyor belts are used to move the packaging boxes, and parts of the packaging boxes are suspended in the air. When passing through the flipping and packing mechanism, the packaging boxes are flipped. The flipping and packing mechanism for the packaging cartons includes a base 1, and a driving component 2 for driving a cross-shaped shell 3 to rotate is installed on the top of the base 1; the cross-shaped shell 3 includes a flipping part 31 and a central part 32, which are interconnected. Openings are provided on the top surfaces of the four flipping parts 31 of the cross-shaped shell 3, and a length adjustment component 5 is provided in the central part 32 for driving four inner blocks 4 to extend from the four openings of the cross-shaped shell 3, thereby increasing the length of the four flipping parts 31 on the cross-shaped shell 3.

[0025] First, place two synchronously running conveyor belts horizontally, leaving enough space between them (not too large to prevent the box from falling from here and affecting transportation during packaging), and then move the packaging mechanism between the two conveyor belts. The driving component 2 drives the rotation of the cross-shaped shell 3 (the driving component 2 can use the intermittent driving device in the prior art), so that the packaging box moved by the two conveyor belts is flipped ninety degrees by the flipping part 31 on the cross-shaped shell 3. When the volume of the packaging box is too large (large box), the flipping part 31 on the cross-shaped shell 3 cannot stably support the flipping of the packaging box due to insufficient length, the inner block 4 can be driven to extend from the cross-shaped shell 3 by the length adjustment component 5, so as to adjust the length of the flipping part 31 to cope with this situation (the total length of the flipping part 31 = the length of the flipping part 31 itself + the length of the inner block 4 extending out of the flipping part 31). Under normal circumstances, the inner block 4 is retracted into the cross-shaped shell 3 by the length adjustment component 5 to reduce the space occupied, which is more practical.

[0026] The length adjustment assembly 5 includes a rotating rod 52 driven by a motor 51, a bevel gear A53 is fixedly connected to the middle of the rotating rod 52, four bevel gears B54 whose axes are parallel to the flip part 31 are meshed and connected on the bevel gear A53, and a screw rod 55 is fixedly connected to the back of the bevel gear B54, and a rod sleeve 56 is threadedly connected to the outer wall of the screw rod 55, and the top of the rod sleeve 56 is fixed to the inner block 4, and a bearing A58 is sleeved on the bottom of the screw rod 55, and the screw rod 55 is fixed in the inner ring of the bearing A58, and the outer ring of the bearing A58 is fixed to the inner wall of the flip part 31 through a transverse plate B510, and a circular groove 57 for the screw rod 55 to pass through is opened inside the inner block 4 (the circular groove 57 is used to prevent the screw rod 55 from being blocked by the inner block 4), and the cross section of the inner block 4 is the same as the internal cross section of the flip part 31 (so that it can limit The rotation of the inner block 4 is controlled so that the inner block 4 can only move linearly along the inside of the flipping part 31). The other end of the rotating rod 52 connected to the motor 51 is rotatably connected to the inner wall of the central part 32 through the bearing B59 (the rotation support of the bearing B59 can make the rotation of the rotating rod 52 more stable). The operation steps are: the forward or reverse rotation of the motor 51 is controlled by the control button, and the motor 51 drives the rotating rod 52 to rotate clockwise or counterclockwise, and the rotating rod 52 drives the bevel gear A53 to rotate clockwise or counterclockwise. The bevel gear A53 drives the screw rod 55 to rotate clockwise or counterclockwise through the bevel gear B54. The screw rod 55 drives the rod sleeve 56 to move back and forth, and the rod sleeve 56 drives the inner block 4 to extend or retract from the flipping part 31, thereby adjusting the length of the flipping part 31. The screw rod 55 is rotationally supported by the bearing A58 during rotation.

[0027] Furthermore, a lifting assembly 6 for adjusting the height of the driving assembly 2 is provided on the base 1, thereby adjusting the height of the cross-shaped shell 3, so that the cross-shaped shell 3 can adapt to conveyor belt machines of different heights.

[0028] The lifting assembly 6 includes a rectangular rod 61 welded to the top of the base 1, and a lifting plate 62 fixed to the bottom of the driving assembly 2. The surface of the lifting plate 62 is provided with through grooves 63 for the rectangular rod 61 to pass through. The side ends of the rectangular rod 61 are provided with multiple screw holes 64 arranged in a vertical array and equidistantly. The side ends of the lifting plate 62 are provided with through holes 65. The tops of the rectangular rods 61 are fixedly connected with limit plates 66 (the limit plates 66 are used to prevent the lifting plate 62 from sliding off the rectangular rods 61). The cross section of the rectangular rod 61 is the same as the cross section of the through groove 63.

[0029] Since the cross section of the rectangular rod 61 is the same as that of the through slot 63, the lifting plate 62 can move up and down along the rectangular rod 61 in a straight line, thereby adjusting the height of the drive assembly 2 and the cross-shaped shell 3. When the height adjustment is completed, the height of the drive assembly 2 and the cross-shaped shell 3 can be fixed by passing the screw through the through hole 65 on the lifting plate 62 and then rotating it clockwise to install it into the screw hole 64 corresponding to the rectangular rod 61, and universal wheels 7 with a locking function are installed around the bottom of the base 1 to facilitate the movement of the mechanism. In this way, it can be adjusted according to different conveyor belts and is convenient to move, so that the mechanism can be conveniently used in conjunction with conveyor belts of different heights. After moving to the appropriate position, the universal wheels 7 are locked to fix the position of the mechanism.
