Description

Technical Field

[0001] The utility model belongs to a packaging machine, in particular to an inner tongue folding mechanism of a packaging paper box. Background Art

[0002] Packaging cartons are widely used in the packaging of various products, especially the packaging of various medical devices, such as various syringes, etc. Figure 6 As shown in the figure, a common syringe packaging box is designed with inner tongues at both ends of the upper mouth of the box body. Before loading the product, the inner tongues at both ends need to be folded inward into a horizontal state. When the product is loaded, it contacts the inner tongues on both sides and is pressed into the box body. The inner tongues play a role in supporting and protecting the product. After loading the product, the upper cover on one side of the upper mouth of the box body is folded inward to seal the box. If the inner tongue is folded manually, not only is the work efficiency low and the labor cost high, but it is also easy to dirty the packaging box. Therefore, it is necessary to design an automatic folding mechanism for the inner tongue of the packaging paper box to replace manual work. Utility Model Content

DETAILED DESCRIPTION

[0023] like Figure 1-Figure 5 As shown, the utility model relates to an inner tongue folding mechanism of a packaging paper box, comprising a horizontally arranged mounting base plate 1, on which a sliding plate 3 is slidably mounted via two transverse slide rail assemblies 4, a servo motor 8 is mounted on the bottom surface of the mounting base plate 1 along a vertical direction via a motor frame, and an output end of the upper end of the servo motor 8 is connected to the sliding plate 3 via a crank slider mechanism, for driving the sliding plate 3 to intermittently reciprocate along the width direction of the mounting base plate 1.

[0024] The crank slider mechanism includes a circular driving disk 14 fixedly clamped on the output end of the servo motor 8. The driving disk 14 passes through a through hole provided on the mounting base plate 1 and an eccentrically arranged pin shaft 13 is inserted on the driving disk 14. A linkage block 7 is fixed to the bottom surface of the sliding plate 3 by screws. A long hole is provided on the linkage block 7. The upper end of the pin shaft 13 is inserted into the strip hole through a clearance fit, so that when the pin shaft 13 rotates with the driving disk 14, it slides back and forth in the long hole, thereby driving the sliding plate 3 to slide back and forth intermittently.

[0025] Limiting plates 2 with internal limiting grooves are fixed to both ends of the sliding plate 3 by screws, and rubber limiting columns 15 are fixed on the mounting base plate 1 corresponding to the limiting plates 2. The limiting columns 15 are inserted into the limiting grooves to achieve sliding limiting of the sliding plate 3.

[0026] Two connecting plates 5 are slidably mounted on the sliding plate 3 through two longitudinal slide rail assemblies 6. The two connecting plates 5 are parallel to each other and staggered. Driving cylinders 10 are fixed on the sliding plate 3 near both ends through cylinder seat plates. The driving cylinders 10 are aligned with the center lines of the two connecting plates 5, and one end of the piston rod is connected to the corresponding connecting plate 5 through a screw and a nut, so as to drive the two connecting plates 5 to slide toward or in the opposite direction.

[0027] F-shaped push handles 9 are evenly fixed on the two connecting plates 5 by screws, one end of the F-shaped push handles 9 extends to the same side of the two connecting plates 5, two adjacent F-shaped push handles 9 are symmetrically arranged and the other ends are fixed on the two connecting plates 5, respectively, and are used to make the two adjacent F-shaped push handles 9 move toward each other under the drive of the connecting plates 5 to achieve simultaneous folding of multiple inner tongues of packaging paper boxes. The F-shaped push handle 9 is composed of a connecting rod 901 and a U-shaped folding piece 902 fixed at one end of the connecting rod, and the outer end of the U-shaped folding piece is turned up to protect the inner tongue of the packaging paper box during folding.

[0028] A protective cover 12 is fixed on the mounting base plate 1 by four columns and screws. The protective cover 12 covers the sliding plate 3, the transverse slide rail assembly, the connecting plate 5, the longitudinal slide rail assembly and the driving cylinder 10. The F-shaped push handle 9 extends out from an opening on one side of the protective cover 12.

[0029] The transverse rail assembly 4 is composed of a transverse rail and two sliders slidably mounted on the transverse rail. The longitudinal rail assembly 6 is composed of a longitudinal rail and three sliders slidably mounted on the longitudinal rail.

[0030] When working, the folding mechanism is installed on the body of the cartoning machine through the mounting base plate 1, and the driving cylinder 10 is in the extended state in the initial state. When the packaging paper box 11 is formed and ready for loading, it is transported to the folding mechanism by the transmission belt, and the servo motor 8 is controlled to start. When the pin shaft 13 on the driving disk 14 rotates with the driving disk 14, it reciprocates in the long hole, and drives the sliding plate 3 to slide to one side of the packaging paper box, thereby driving the F-shaped push handle 9 to be inserted into the two sides of each packaging paper box 11 respectively.

[0031] Then, the two driving cylinders 10 are controlled to start retracting at the same time, and each pair of adjacent F-shaped pushers 9 are driven to move toward each other through the two connecting plates 5, so that the inner tongues 111 at both ends of each packaging carton are folded inward from a vertical state to a horizontal state. After the folding of the inner tongues is completed, the cylinders are controlled to extend, and each pair of adjacent F-shaped pushers 9 are driven to move in the opposite direction to exit the packaging carton;

[0032] Finally, the servo motor 8 is controlled to start, and the sliding plate 3 is driven to reset through the crank slider mechanism, thereby driving the F-shaped push handle 9 to return to the initial position to prepare for the next action.

[0033] Although the implementation scheme of the utility model has been disclosed as above, it is not limited to the applications listed in the specification and implementation modes. It can be fully applied to various fields suitable for the utility model. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the utility model is not limited to the specific details and the illustrations shown and described herein.
