Description

Technical Field

[0001] This utility model relates to a packaging machine, specifically a carton opening and pressing mechanism applied to a cartoning machine. Background Technology

[0002] Currently, cartoning machines are used to integrate and package materials (such as blister packs), instructions (paper blister pack instructions), and cardboard boxes into small packaging boxes. These small packaging boxes are then integrated and packaged into medium-sized packaging boxes (i.e., boxes within boxes). This involves the primary and secondary packaging of various types of items such as food, medicine, and cosmetics, and has a large market demand.

[0003] These types of cardboard boxes are generally square and already open. If the cardboard box is a novel flat sleeve box, it is a flat sleeve box with two-way openings (material usage instructions can be printed directly on its outer surface). The flat sleeve box needs to be expanded and opened first, the material edges flattened, and then individual pieces of material inserted. Multiple boxes are then integrated into a medium-sized packaging box. This flat sleeve box does not require special instruction materials or a box-closing process, making it very convenient to use and destined for widespread application. Currently, the flat sleeve box is opened, pressed, and filled manually, resulting in low work efficiency and high labor intensity, which is not conducive to mass production applications.

[0012] Figure 2 for Figure 1 A schematic diagram of the installation structure of the circulating lifting and pressing device.

[0013] Figure 3 This is a schematic diagram of a flat box and the material (single blister pack) being packaged together. Detailed Implementation

[0014] Reference Figure 1 As can be seen, this utility model applies to the automatic opening and pressing mechanism of a flat box in a cartoning machine, including a main archway 1 (on the right), a secondary archway 2 (on the left), and a frame 20 (at the front). A flat box conveying device 21 is mounted on the main archway 1, a material conveying device 22 is mounted on the secondary archway 2, and a flat box transport device 23 at the front and a material transport device 24 at the rear are mounted on the frame 20. A circulating lifting pressing device 25 is mounted on the main archway 1, between the flat box conveying device 21 and the material transport device 24. Figure 1 , Figure 2 As shown, the circulating lifting and pressing device 25 includes pressing arches 31 (one is mounted on the main arch 1 on the inside, and the other is mounted on the outside). On the two sides of the pressing arches 31, pressing main drive shaft 34 (on the right side) and pressing secondary drive shaft 36 (on the left side) are respectively installed. On both sides of the pressing main drive shaft 34 and pressing secondary drive shaft 36, there are two sprocket and chain assemblies 35 (two pieces, circulating on the outside) and pressing track plates 42 (two pieces, on the inside). On the pressing track plates 42 (via cam bearing 41), there are several slide rail fixing blocks 40. On the slide rail fixing blocks 40, pressing blocks 43 are installed via pressing telescopic slide rods 39 (two pieces).

[0015] A pressing telescopic base plate 37 is mounted on the sprocket and chain assembly 35 (its chain). The pressing telescopic slide rod 39 passes through the pressing telescopic base plate 37 (the pressing telescopic base plate 37 is located between the pressing block 43 and the slide rail fixing block 40). A telescopic linear bearing 38 is mounted on the pressing telescopic slide rod 39 and at the pressing telescopic base plate. The pressing block 43 has a "U" shaped structure and is located above the material compartment 7. The pressing main drive shaft 34 is connected to the pressing power source 33 (a pressing drive motor, mounted on the drive motor base 32). The slide rail fixing block 40 (and cam bearing 41), the pressing telescopic slide rod 39 (two pieces), the pressing block 43, the pressing telescopic base plate 37, and the telescopic linear bearing 38 (two pieces) are assembled in several sets. The pressing track plate 42 has a track groove that allows the slide rail fixing block 40, the pressing telescopic slide rod 39, and the pressing block 43 to gradually rise or fall, and the cam bearing 41 slides on the track groove.

[0016] The flat box conveying device 21 includes a box hopper assembly 9 and a box feeding turntable 10 mounted on the main archway 1. Box suction assemblies 11 (one on each of the three equal parts of the turntable) are mounted around the periphery of the turntable 10. A pair of suction cup assemblies 12 are mounted on the main archway 1 and on the side of the turntable 10. The material conveying device 22 includes a material hopper assembly 3 and a feeding turntable 4 mounted on the secondary archway 2. Suction assemblies 5 (one on each of the two equal parts of the turntable) are mounted around the periphery of the feeding turntable 4.

[0017] The flat box conveyor 23 includes a wraparound box conveyor belt assembly 14 mounted on the front of the frame. Several box compartments 13 are mounted on the wraparound box conveyor belt assembly 14 (its conveyor belt), with spacing between the compartments and located below the suction assembly 11. The material conveyor 24 includes a wraparound material conveyor belt assembly 8 mounted on the rear of the frame. Several material compartments 7 are mounted on the wraparound material conveyor belt assembly 8 (its conveyor belt), with spacing between the compartments and located below the suction assembly 5. A sliding support 16 is mounted on the rear of the frame 20, on the side (leftmost end) of the wraparound material conveyor belt assembly 8. A sliding grid platform 6 is mounted on the sliding support 16, positioned above the material compartments 7. This facilitates the suction assembly 5 placing material onto the sliding grid platform 6, allowing the material to accurately slide into the material compartments 7. A material photoelectric detector 26 is installed at the rear of the frame 20 above the material compartment 7, and a box photoelectric detector 15 is installed at the front of the frame 20 above the box compartment 13. The material photoelectric detector 26 is used to detect whether the material has been conveyed to the correct position, and the box photoelectric detector 15 is used to detect whether the flat box has been conveyed to the correct position.

[0018] like Figure 1 As shown, a material pushing device is also installed on the frame 20 and at the rear of the material conveying device 24, for pushing the material (which has been flattened) in the material compartment into the flat box in the boxing compartment. A front baffle plate 17 is also installed on the frame 20 and at the front of the flat box conveying device 23 to prevent the flat box from moving during loading. A box ejection pressure roller 18 is installed on the front of the frame 20 and on the side (rightmost end) of the wraparound box conveyor assembly 14. A box ejection slide plate 19 is installed on the frame 20 and below the box ejection pressure roller 18. When the flat box after loading is conveyed downward by the wraparound box conveyor assembly 14, it will detach from the boxing compartment, be flattened by the box ejection pressure roller 18, and finally slide out from the box ejection slide plate 19 to the next station. The boxing process of the flat box 27 and the material 28 (single blister pack) involved in this utility model is as follows: Figure 3 As shown.

[0019] As shown in the attached diagram, the working principle of this utility model is as follows: the suction assembly 11 on the periphery of the box feeding turntable 10 of the flat box conveying device 21 picks up a single flat box from the box hopper assembly 9, then rotates to the left to the split suction cup assembly 12, where the split suction cup assembly 12 gently sucks up the flat box to open it in both directions. The box then rotates downwards and is conveyed and placed into the box compartment 13 that has just risen (the newly risen box compartment has a slight error in the capacity compared to the box compartment during transport, which is beneficial for placing the flat box and keeping it open). The flat box remains open in both directions and continues to be transported to the right by the wraparound conveyor belt assembly 14 of the flat box transport device 23; at the same time, the suction assembly 5 on the periphery of the feeding turntable 4 of the material conveying device 22 sucks up the material (single tablet) from the material bin assembly 3, and then rotates downward to be placed into the material compartment 7 that has just risen (or placed on the sliding grid platform 6 and accurately slid into the material compartment 7), and then continues to be transported to the right by the wraparound conveyor belt assembly 8 of the material transport device 24.

[0020] At this time, the pressing power source 33 of the circulating lifting pressing device 25 operates, driving the pressing main drive shaft 34 (on the right) and the pressing secondary drive shaft 36 (on the left) to rotate simultaneously. The sprocket and chain assembly 35 also rotates in a circular motion. Several slide rail fixing blocks 40 move simultaneously on the track groove of the pressing track plate 42 through cam bearings 41, and several pressing telescopic base plates 37 also move simultaneously with the sprocket and chain assembly 35. Thus, the pressing block 43 is gradually lowered by the up-and-down telescopic sliding rod 39. Finally, the pressing block flattens all four sides of the material in the material compartment, making full preparation for the next step of pushing the material into the box (completed by the material pushing device). The pressing block gradually descends from the leftmost position below the pressing arch, flattens the material around the perimeter, and gradually rises from the rightmost position. When the pressing block is above the pressing arch, its height remains unchanged. This utility model can be directly connected to an automatic cartoning machine.
