Description

Technical Field

[0001] The utility model relates to the technical field of product packaging, and particularly relates to a box forming device. Background Art

[0002] A packaging machine is a type of machine that packages products, playing the roles of protection and aesthetics. Packaging machines are mainly divided into two aspects: 1. Pipeline-style integrated production packaging, 2. Product peripheral packaging equipment. Among them, during pipeline-style integrated production packaging, when packaging, it is necessary to expand a folded and flattened box into a rectangle, so as to facilitate putting products into the box from the openings on both sides of the box, and then entering the next process. Existing packaging machines mainly use extrusion from both sides of the folded box to expand the box. However, initially, the upper and lower parts of the folded box are tightly attached to each other, and this operation method is likely to cause problems such as difficult expansion of the box and extrusion deformation.

[0003] Therefore, the inventor provides a box forming device. Summary of the Utility Model

[0023] The present utility model will be specifically described below with reference to the accompanying drawings.

[0024] As shown in Figure 1 to Figure 6 shown, Specific Embodiment:

[0026] A packaging box forming device includes a packaging box feeding mechanism, a box - taking and pre - forming mechanism, and a forming and box - placing mechanism.

While the negative - pressure chamber 8 and the fixed shaft 9 are rotating, a sealing treatment is performed to avoid air leakage; the negative - pressure chamber 8 is connected to a rotation driving mechanism; when the first suction cup 1 moves above the rotating wheel 5, the first suction cup 1 and one of the second suction cups 6 respectively adsorb the top and bottom of the folded - flat packaging box. The guiding column moves left - upper through the ascending curve - segment guiding groove 41, and the rotating wheel 5 rotates right - lower to stretch the folded packaging box into a state with a parallelogram cross - section to complete pre - forming; the forming and box - placing mechanism squeezes the pre - formed packaging box into a state with a rectangular cross - section and places it on the packaging box conveying mechanism.

[0027] The packing box feeding mechanism includes a feeding bin 11 with an open top and a pushing component. The packing boxes folded into a flat shape are stacked in the feeding bin 11. The box-taking preforming mechanism sucks the packing box at the top of the feeding bin 11 one by one, and the pushing component is used to push the lower packing box upward after the box-taking preforming mechanism has sucked the packing box.

[0028] Specifically, the pushing component includes a push plate arranged at the bottom of the feeding bin 11. The push plate is fixedly connected to a first driving nut 12. The first driving nut 12 is threadedly connected to a first screw rod 13. The first screw rod 13 is rotatably connected to a first base 14. The first screw rod 13 is fixedly connected to the movable end of a first motor 15. The first driving nut 12 is slidably connected to a first guide rail 16. The first motor 15 drives the first screw rod 13 to rotate, thereby driving the first driving nut 12 to move up and down, and further driving the push plate to push the packing box.

[0029] The horizontal driving component includes a second driving nut 17 fixedly connected to the U-shaped guiding frame 2. The second driving nut 17 is threadedly connected to a second screw rod 18.

The second driving nut 17 is slidably connected to a second guide rail 21. The second motor 20 drives the second screw rod 18 to rotate, and further drives the second driving nut 17 to move horizontally. The U-shaped guiding frame 2 and the first suction cup 1 move horizontally with the second driving nut 17. Since the first suction cup 1 is fixedly connected to the slider 3 and the slider 3 is slidably connected to the U-shaped guiding frame 2, the first suction cup 1 will move up and down along the guiding groove 4 during the horizontal movement. Therefore, it will move obliquely upward along the rising curve section of the guiding groove 41.

[0030] The forming and box-releasing mechanism includes a fixing plate 22. A vertical third guide rail 23 is provided on the fixing plate 22. A lifting plate 24 is slidably connected to the third guide rail 23. A clamping and shaping mechanism is provided on the lifting plate 24.

Two hinge rods 27 are provided on the back of the first fixing plate 22 and are respectively hinged to the two clamping blocks 25. The other ends of the two hinge rods 27 are symmetrically and eccentrically hinged to a turntable 28. The turntable 28 is eccentrically hinged to the movable end of a cylinder 29. The fixed end of the cylinder 29 is hinged to the fixing plate 22. The cylinder 29 pushes the turntable 28 to rotate. The turntable 28 pulls the two clamping blocks 25 to approach or separate from each other through the two hinge rods 27. During the process of the two clamping blocks 25 approaching each other in the middle, the preformed packing box (in the state of a parallelogram cross-section) will be squeezed into a fully formed packing box (in the state of a rectangular cross-section). The first suction cup 1 is released, and the clamped packing box descends with the lifting plate 24 and is placed on the packing box conveying mechanism.

[0031] The guiding groove 4 further includes a first straight guiding groove 42 disposed in front of the ascending curve guiding groove 41, a descending curve guiding groove 43 and a second straight guiding groove 44 disposed behind the ascending curve guiding groove 41. Corresponding optoelectronic switches 30 are provided at both ends of the guiding groove 4. The positions of sucking the packaging box at the initial stage and placing the packaging box at the end stage are judged through the optoelectronic switches 30 to ensure the positioning necessary for the coordinated work among various mechanisms.

[0032] A plurality of limiting blocks 31 are evenly arranged on the packaging box conveying mechanism, and the formed packaging boxes are placed between two limiting blocks. The limiting blocks 31 can prevent the formed packaging boxes from being deformed again during the conveying process, which is convenient for putting products into the packaging boxes during the conveying process.
