Description

Technical Field

[0001] This invention relates to the field of packaging equipment, and more particularly to a box sealing device. Background Technology

[0002] Packaging boxes are primarily used to facilitate logistics transportation, loading, unloading, and warehousing. They are generally made of wood or corrugated solid wood pallets, but tin drums or galvanized iron drums are also used. Paper packaging boxes are also common, with paper boxes being the most widely used. Sheet-type packaging boxes are created by transforming the sheet-type packaging box into a box with openings at both ends. The items to be packaged are then filled inside, and the openings are manually sealed. However, manually bending cardboard to seal the openings is inefficient.

[0003] This invention was proposed in response to the shortcomings of existing technologies. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a packaging box sealing device.

[0005] This invention can be achieved through the following technical solutions:

[0006] This invention discloses a box sealing device, comprising a frame, a box-lifting slide slidably connected to the frame, and a box-lifting timing belt driven by a box-lifting motor. The timing belt is fixed to the box-lifting slide, and a box-lifting fixing plate is provided on the box-lifting slide. Box-lifting lifting cylinders are symmetrically fixed on both sides of the box-lifting slide. A box-lifting mounting plate is fixed to the piston rod end of each lifting cylinder, and a box-lifting rotating cylinder is fixed to each mounting plate.

[0024] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings:

[0025] Example 1:

[0026] like Figures 1 to 7As shown, this embodiment discloses a packaging box sealing device, including a frame 1. A box-lifting slide 703 is slidably connected to the frame 1. A box-lifting timing belt 701 is also provided on the frame 1. The box-lifting timing belt 701 is driven to rotate by a box-lifting motor 702. The box-lifting timing belt 701 is fixed to the box-lifting slide 703. A box-lifting fixing plate 707 is provided on the box-lifting slide 703. Box-lifting lifting cylinders 713 are symmetrically fixed on the box-lifting slides 703 on both sides of the box-lifting fixing plate 707. A box-lifting mounting plate 714 is fixed to the end of the piston rod of each box-lifting cylinder 713. A box-lifting rotating cylinder 715 is fixed to the end of the piston rod of each box-lifting rotating cylinder 715. A box-lifting positioning shaft 716 is fixed to the end of each box-lifting positioning shaft 716. A box-lifting push plate 717 is fixed to each box-lifting positioning shaft 716. The frame 1 is also equipped with a carton sealing device 8, which includes a sealing timing belt 805 set on both sides of the carton taking fixing plate 707. The sealing timing belt 805 is driven to rotate by the sealing motor 801. The frame 1 is also symmetrically fixed with sealing crossbars 809 on both sides. The frame 1 above the sealing crossbars 809 is fixed with upper sealing rods 810. The frame 1 below the sealing crossbars 809 is fixed with lower sealing rods 811. The frame 1 above the upper sealing rods 810 is fixed with bending devices 812. The frame 1 below the lower sealing rods 811 is also fixed with bending devices 812. The bending devices 812 include bending cylinders 813 fixed on the frame 1. The piston rod of the bending cylinder 813 is fixed with bending rods 814. Bending pressure rollers 815 are set on the bending rods 814.

[0027] Among them, multiple box-removing cylinders 709 are fixed on the box-removing fixing plate 707, and multiple suction cups 708 are fixed on each box-removing cylinder 709.

[0028] The box-retrieving fixing plate 707 has a box-retrieving positioning plate 712 fixed on one side, and a box-retrieving cylinder 709 is also fixed on the box-retrieving positioning plate 712. Multiple suction cups 708 are fixed on the box-retrieving cylinder 709. The suction cups 708 are connected to a vacuum pump through air pipes. The vacuum pump evacuates the suction cups 708, creating a negative pressure at the position of the suction cups 708. The suction cups 708 fix the packaging box 15, increasing the stability of the movement of the packaging box 15. When the packaging box 15 moves onto the two sealing synchronous belts 805, the box-retrieving cylinder 709 is activated, the piston rod on the box-retrieving cylinder 709 shortens, and the suction cups 708 separate from the packaging box 15.

[0029] Multiple sealing push blocks 806 are evenly fixed on the sealing timing belt 805. The sealing push blocks 806 rotate with the sealing timing belt 805. After the sealing push blocks 806 come into contact with the packaging box 15, they push the packaging box 15 to move, and the packaging box 15 moves with the sealing timing belt 805.

[0030] The frame 1 is equipped with a sealing drive shaft 802, and sealing main pulleys 803 are symmetrically fixed on both sides of the sealing drive shaft 802. The sealing drive shaft 802 is driven to rotate by the sealing motor 801. The frame 1 is equipped with a sealing driven shaft at a position corresponding to the sealing main pulleys 803. The sealing driven shaft is fixed with a sealing driven pulley 804. The sealing driven pulleys 804 are all connected to the sealing main pulleys 803 through a sealing synchronous belt 805.

[0031] The packaging box 15 has a left cardboard 151 on the left side of the opening, side cardboard 153 on the top and bottom sides of the opening, and a right cardboard 152 on the right side of the opening.

[0032] Example 2:

[0033] This embodiment discloses a packaging box sealing device. Based on the structure and principle of Embodiment 1, the frame 1 of this embodiment is further equipped with a pressing synchronous belt 807, which is driven to rotate by a pressing motor 808. After the openings at both ends of the packaging box 15 are sealed, it moves with the sealing synchronous belt 805. The upper end of the packaging box 15 is pressed down by the pressing synchronous belt 807 to ensure that the packaging box 15 moves forward stably.

[0034] Working principle: The packaging box 15 to be sealed is fixed on the box-retrieving fixing plate 707 and moves with the box-retrieving slide 703. The box-retrieving lifting cylinder 713 is activated, the piston rod on the box-retrieving lifting cylinder 713 extends, the box-retrieving rotating cylinder 715 rises, and the box-retrieving push plate 717 rises with the box-retrieving rotating cylinder 715. After both box-retrieving push plates 717 reach the right cardboard 152 side of the corresponding position, the box-retrieving rotating cylinder 715 is activated, driving the box-retrieving positioning shaft 716 to rotate, and the box-retrieving push plate 717... As the box-retrieving positioning shaft 716 rotates, the box-retrieving push plate 717 contacts the right cardboard 152 and pushes it to rotate, covering the opening of the packaging box 15. When the packaging box 15 moves, the left cardboard 151 contacts the sealing bar 809, which pushes the left cardboard 151 to cover the opening of the packaging box 15. After the right cardboard 152 also covers the opening of the packaging box 15, the packaging box 15 continues to move. When the right cardboard 152... After reaching the sealing bar 809, the right cardboard 152 is blocked by the sealing bar 809. The bending cylinder 813 is activated, and the piston rods of all four bending cylinders 813 extend. The bending rods 814 all move, and the bending pressure rollers 815 push the corresponding side cardboard 153 to bend. After the side cardboard 153 covers the opening of the packaging box 15, the sealing motor 801 drives the sealing timing belt 805 to rotate. The pusher 806 on the sealing timing belt 805 contacts the packaging box 15 and pushes the packaging box 15. As the packaging box 15 moves, it enters between the sealing timing belt 805 and the pressing timing belt 807 and moves with the sealing timing belt 805. When the packaging box 15 moves, the side cardboard 153 is blocked by the upper sealing rod 810 and the lower sealing rod 811, so that the side cardboard 153 covers the opening of the packaging box 15. When the packaging box 15 moves, the box-removing push plate 717 is pulled out from the packaging box 15 and returns to its initial position. After the side cardboard 153 covers the opening of the packaging box 15, it moves with the packaging box 15.

[0035] The above are merely preferred embodiments of the present invention. It should be noted that, for those skilled in the art, various changes, modifications, substitutions and variations can be made to these embodiments without departing from the technical principles of the present invention. These changes, modifications, substitutions and variations should also be considered within the scope of protection of the present invention.
