[0002] At present, the cartoning machine is a device that integrates materials (such as blister medicine plates), instructions (paper medicine plate instructions for use), paper boxes, etc. into small packaging boxes, and then integrates multiple small packaging boxes and repackages them into medium packaging boxes (i.e. box-in-box). It involves the initial and secondary packaging of various types of items such as food, medicine, cosmetics, etc., and has a large market demand space.

[0003] This type of paper box is generally a square paper box, which is already in an open state; if the paper box is a novel flat box, that is, a flat box with two-way openings (the material instructions can be directly printed on its outer surface), it is necessary to expand and open the flat box first, flatten the periphery of the material (if it is slightly uneven, it cannot be put into the box), and then put the single piece of material into the box, and then multiple boxes are integrated into a medium packaging box. This flat box does not require special instruction materials, nor does it require a paper box closing process. It is very convenient to use and will surely be promoted and applied. At present, the flat box is opened, pressed and loaded manually, which has low work efficiency and high labor intensity, and is not conducive to mass production and application. Summary of the invention

[0004] The object of the present invention is to overcome the above technical deficiencies and to provide a flat sleeve automatic opening and pressing mechanism which can automatically convey and open the flat sleeve and automatically convey and flatten the material.

[0006] The flat box conveying device comprises a box bin assembly and a box feeding turntable mounted on the main arch, a box suction assembly is mounted on the periphery of the box feeding turntable, and a split suction cup assembly is mounted on the main arch and on the side of the box feeding turntable. The material conveying device comprises a material bin assembly and a feeding turntable mounted on the secondary arch, and a material suction assembly is mounted on the periphery of the feeding turntable.

[0007] The flat box transport device comprises a wraparound box transport belt assembly mounted on the front of the frame, on which a plurality of box compartments are mounted, the box compartments are spaced apart and are located below the box suction assembly. The material transport device comprises a wraparound material transport belt assembly mounted on the rear of the frame, on which a plurality of material compartments are mounted, the material compartments are spaced apart and are located below the material suction assembly.

[0008] The circulating lifting and lowering press device comprises a press arch, on both sides of which a press main transmission shaft and a press secondary transmission shaft are respectively mounted, on both sides of the press main transmission shaft and the press secondary transmission shaft are mounted sprocket chain components and a press track plate, on which a plurality of slide rail fixing blocks are mounted, and on which a press block is mounted via a press telescopic slide rod. A press telescopic bottom plate is mounted on the sprocket chain component, and the press telescopic slide rod passes through the press telescopic bottom plate, and telescopic linear bearings are mounted on the press telescopic slide rod and at the press telescopic bottom plate.

The material conveying device 22 includes a material bin assembly 3 and a feeding turntable 4 mounted on the secondary arch 2, and a material suction assembly 5 (one for each of the two equal parts of the feeding turntable) is mounted on the periphery of the feeding turntable 4.

[0016] The flat box transport device 23 includes a wraparound box transport belt assembly 14 mounted on the front of the frame, and a plurality of box compartments 13 are mounted on the wraparound box transport belt assembly 14 (its box transport belt), and the box compartments are spaced apart and are located below the suction box assembly 11. The material transport device 24 includes a wraparound material transport belt assembly 8 mounted on the rear of the frame, and a plurality of material compartments 7 are mounted on the wraparound material transport belt assembly 8 (its material transport belt), and the material compartments are spaced apart and are located below the suction component 5. A sliding material bracket 16 is mounted on the rear of the frame 20 and at the side edge (leftmost end) of the wraparound material transport belt assembly 8, and a sliding material grid platform 6 is mounted on the sliding material bracket 16, and the sliding material grid platform 6 is located above the material compartment 7, which is conducive to the suction component 5 to discharge the material on the sliding material grid platform 6 and the material accurately slides into the material compartment 7. A material photoelectric detector 26 is installed above the material compartment 7 at the rear of the frame 20, and a box photoelectric detector 15 is installed above the box compartment 13 at the front of the frame 20. The material photoelectric detector 26 is used to detect whether the material is delivered in place, and the box photoelectric detector 15 is used to detect whether the flat box is delivered in place.

[0017] like Figure 1 , Figure 2As shown, the circulating lifting and lowering press device 25 includes a press arch 31 (one piece is installed on the main arch 1 internally, and the other piece is installed on the outside), and a press main transmission shaft 34 (on the right side) and a press auxiliary transmission shaft 36 (on the left side) are installed on both sides of the press arch 31 respectively, and a sprocket chain assembly 35 (two pieces, circulating on the outside) and a press track plate 42 (two pieces, on the inside) are installed on both sides of the press main transmission shaft 34 and the press auxiliary transmission shaft 36, and a plurality of slide rail fixing blocks 40 are installed on the press track plate 42 (through a cam bearing 41), and a press block 43 is installed on the slide rail fixing block 40 through a press telescopic slide rod 39 (two pieces). A material pressing telescopic bottom plate 37 is installed on the sprocket chain assembly 35 (its chain), and the material pressing telescopic slide rod 39 passes through the material pressing telescopic bottom plate 37 (the material pressing telescopic bottom plate 37 is between the material pressing block 43 and the slide rail fixing block 40), and a telescopic linear bearing 38 is installed on the material pressing telescopic slide rod 39 and at the material pressing telescopic bottom plate. The material pressing block 43 is a "U"-shaped structure, and the material pressing block 43 is above the material compartment 7. The material pressing main transmission shaft 34 is connected to the material pressing power source 33 (which is a material pressing drive motor, installed on the drive motor seat 32). The slide rail fixing block 40 (and cam bearing 41), the material pressing telescopic slide rod 39 (two pieces), the material pressing block 43, the material pressing telescopic bottom plate 37, and the telescopic linear bearing 38 (two pieces) are combined into several sets. The press track plate 42 has a track groove that enables the slide rail fixing block 40, the press telescopic slide rod 39, and the press block 43 to gradually rise or fall, and the cam bearing 41 slides on the track groove.

[0018] like Figure 1 As shown, a material pushing device is also installed on the frame 20 and at the rear of the material transport device 24, which is used to push the materials (which have been flattened) in the material compartment into the flat sleeves in the sleeve compartment. A front box baffle 17 is also installed on the frame 20 and at the front of the flat sleeve transport device 23 to prevent the flat sleeves from being moved when loading. A box discharge pressing wheel 18 is installed on the front of the frame 20 and at the side (rightmost end) of the surrounding box transport belt assembly 14. A box discharge slide plate 19 is installed on the frame 20 and below the box discharge pressing wheel 18. When the loaded flat sleeves are transported downward by the surrounding box transport belt assembly 14, they will be separated from the sleeve compartment, and then the box discharge pressing wheel 18 will flatten the whole, and finally slide out from the box discharge slide plate 19 to the next station.

[0019] As shown in the accompanying drawings, the working principle of the present invention is as follows: a single flat box is sucked from the box bin assembly 9 by the box suction assembly 11 on the periphery of the box delivery turntable 10 of the flat box conveying device 21, and then rotates to the left to run to the split suction cup assembly 12, and the split suction cup assembly 12 gently sucks the flat box to open the two-way opening, and then rotates downward to run and convey and place it in the box compartment 13 that has just risen (the box compartment that has just risen and the box compartment that is being transported have a slight error in the accommodation space, which is conducive to the placement of the flat box and keeping it in an open state) , and the flat box keeps the two-way opening open, and continues to be transported to the right by the surrounding box conveying belt assembly 14 of the flat box conveying device 23; at the same time, the suction assembly 5 on the periphery of the feeding turntable 4 of the material conveying device 22 absorbs the material (single-piece medicine plate) from the material silo assembly 3, and then rotates downward to convey and place it in the material compartment 7 that has just risen (or places it on the sliding grid platform 6 and accurately slides into the material compartment 7), and then continues to be transported to the right by the surrounding conveying belt assembly 8 of the material conveying device 24.

[0020] At this time, the pressing power source 33 of the circular lifting pressing device 25 works, driving the pressing main transmission shaft 34 (on the right) and the pressing secondary transmission shaft 36 (on the left) to rotate and run at the same time, and the sprocket chain assembly 35 also runs in a circular manner, and a number of slide rail fixing blocks 40 run simultaneously on the track groove of the pressing track plate 42 through the cam bearing 41, and a number of pressing telescopic bottom plates 37 also run simultaneously with the sprocket chain assembly 35, so that the pressing block 43 is gradually lowered downward through the up and down telescopic movement of the pressing telescopic slide rod 39, and finally the pressing block flattens the surroundings of the materials in the material compartment, making full preparations for the next step of pushing the materials into the box (completed by the material pushing device). The pressing block gradually descends from the leftmost side of the bottom of the pressing arch, flattens the surroundings of the materials, and gradually rises from the rightmost side. When the pressing block runs above the pressing arch, the height can remain unchanged.

[0021] The present invention can be directly connected to an automatic cartoning machine. The process of packing the flat box 27 and the material 28 (single-piece medicine board) according to the present invention is as follows: Figure 3 shown.
