Description

Technical Field

[0001] This utility model relates to the field of packaging equipment technology, and in particular to a folding mechanism for box conveying. Background Technology

[0002] Packaging boxes are used to package products and ensure their safety during transportation. When placing products into packaging boxes, the boxes need to be opened first, and then the products are placed inside one by one. After placement, the packaging boxes carrying the products need to be conveyed to the next process. When folding and sealing the sides of the packaging boxes, the traditional manual folding method is too inefficient to keep up with the speed of automated product loading, and it cannot guarantee a uniform folding effect each time. This affects the product qualification rate. How can the folding action be completed synchronously during the conveying of packaging boxes, thereby reducing manual intervention and improving the product qualification rate? Therefore, a folding mechanism for box conveying is needed to solve the above-mentioned problems. Utility Model Content

[0024] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. It should be noted that, unless otherwise specified, the following embodiments and features can be combined with each other.

[0025] Please see Figures 1 to 5This utility model provides a folding mechanism for box conveying, including a box conveying frame 2 on a machine base 1, a box rack 3 in the feeding direction of the box conveying frame 2, the box rack 3 providing packaging boxes to the box conveying frame 2, a conveying slide 4 inside the box conveying frame 2, the conveying slide 4 conveying the packaging boxes to the next process, and folding components along both sides of the conveying slide 4 to fold the packaging boxes.

[0026] The folding assembly includes a folding base 5 mounted on the machine base 1. A folding frame 6 is slidably connected to the folding base 5. A pre-folding plate 7 and a main folding plate 8 are sequentially arranged on the folding frame 6 along the conveying direction of the conveyor slide 4. The pre-folding plate 7 is used to pre-process the side of the packaging box, and the main folding plate 8 presses the pre-processed side tightly. A pre-folding ramp 9 is provided at the front end of the pre-folding plate 7 near the conveyor slide 4. The pre-folding ramp 9 is gradually moved closer to the conveying working surface in the direction away from the conveyor slide 4. When the pre-folding plate 7 moves in the direction closer to the conveyor slide 4, the upper and lower sides of the packaging box are in a raised state, but this state is maintained parallel to the main body of the packaging box. The pre-folding ramp 9 is used to press the side of the packaging box towards the main body of the packaging box, so that the side of the packaging box can tilt towards the main body of the packaging box.

[0027] A straight folding table 10 is provided at the front end of the main folding plate 8 near the conveyor slide 4. The straight folding table 10 then presses the side that has been tilted towards the main body of the packaging box onto the main body of the packaging box, thereby avoiding damage caused by directly pressing the side of the packaging box. A folding drive 11 is provided on the machine base 1. The folding drive 11 drives the folding frame 6 to reciprocate along the conveying direction perpendicular to the conveyor slide 4. After the folding action of a packaging box is completed, the conveyor slide 4 sends the packaging box to the next process, and the folding frame 6 repeats the folding action for the next packaging box.

[0028] Two sets of folding frames 6 are symmetrically arranged on both sides of the conveyor slide 4. The two sets of folding frames 6 are arranged with a height difference, which can perform folding action on both sides of the packaging box. In addition, the height difference is matched with the thickness of the packaging box to ensure that the packaging box is not damaged during the folding process.

[0029] The movable end of the folding drive component 11 is provided with a lifting slide 12. The folding drive component 11 drives the lifting slide 12 to move up and down on the machine base 1. A drive link 13 is provided between the lifting slide 12 and the folding frame 6. The drive link 13 is an angled drive link 13. The turning point of the drive link 13 is hinged to the folding base 5. After the two ends of the drive link 13 are respectively hinged to the folding frame 6 and the lifting slide 12, when the folding drive component 11 drives the lifting slide 12 to move up and down, the lifting movement of the lifting slide 12 can be converted into rotation around the turning point of the drive link 13, thereby allowing the folding frame 6 to slide along the folding base 5.

[0030] The lifting slide 12 is provided with a folding slide 14, and a drive pulley 15 is rotatably connected to the drive link 13. The drive pulley 15 slides and is slidably engaged with the folding slide 19. The folding slide 19 can ensure the stability of the drive link 13 as it moves with the folding drive component 11.

[0031] A conveyor slider 16 is slidably connected to the folding base 5. A folding base 17 is provided between the bottom of the folding frame 6 and the conveyor slider 16. A folding groove 19 is provided on the folding base 17. A folding pulley 18 is provided on the drive linkage 13. The folding pulley 18 is slidably engaged with the folding groove 19. By using the folding pulley 18 slidably connected in the folding groove 19, the rotation of the drive linkage 13 can be stably converted into the sliding of the conveyor slider 16 on the folding base 5. This allows the folding frame 6 to reciprocate along the conveying direction perpendicular to the conveyor slide 4 to complete the folding action of the packaging box.

[0032] A box drive frame 20 is provided on the lower side of the conveyor slide 4. A liftable drive base 21 is provided at the bottom of the box drive frame 20. The drive base 21 is arranged along the conveying direction of the conveyor slide 4. The box drive frame 20 is slidably connected to the drive base 21. A conveyor drive rod 22 is provided inside the machine base 1. The conveyor drive rod 22 drives the box drive frame 20 to slide on the drive base 21. When it is necessary to push the packaging box to move along the conveyor slide 4, the drive base 21 rises to the conveying height so that the box drive frame 20 can contact the packaging box. The conveyor drive rod 22 is provided inside the machine base 1, and then the conveyor drive rod 22 drives the box drive frame 20 to slide on the drive base 21, thereby conveying the packaging box to the next station. After the conveying action is completed, the drive base 21 is lowered to the non-conveying height. The conveyor drive rod 22 drives the box drive frame 20 to slide backward on the drive base 21 to repeat the conveying action for subsequent packaging boxes.

[0033] The conveying drive rod 22 is oscillatingly connected to the machine base 1. One end of the conveying drive rod 22 is connected to the drive base 21, which is a movable end. The drive base 21 is provided with a drive slide rail 23. The box drive frame 20 is provided with a drive slide groove 25 on one side. A drive roller 26 is provided between the conveying drive rod 22 and the drive slide groove 25. The drive roller 26 is rotatably connected to the conveying drive rod 22. When the conveying drive rod 22 oscillates, the drive roller 26 slides between the drive slide groove 25, thereby converting the oscillation action of the conveying drive rod 22 into driving the box drive frame 20 to slide along the drive slide rail 23. A drive slider 24 is provided between the bottom of the box drive frame 20 and the drive slide rail 23. The drive slider 24 can improve the movement stability of the box drive frame 20.

[0034] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit this utility model. All equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
