Description

Technical Field

[0001] The utility model relates to the technical field of packaging machinery, in particular to a packaging box opening mechanism and a box packing device. Background Art

[0002] See attached Figure 1 The packaging box shown mainly includes a box body and four flaps arranged at the box port. At present, in the packaging industry, in order to improve packaging efficiency and reduce the labor intensity of workers, manual labor is gradually replaced by machinery. The whole process from product grabbing to boxing is realized by replacing manpower with packaging machinery. When the product is grabbed by a robot and placed in the box, the best packing effect is to make the four flaps present a trumpet shape, which increases the cross-section of the box port and facilitates the robot to enter the box.

[0003] The current announcement number is CN 106516225 Patent B, with an announcement date of December 14, 2018, discloses a cartoning machine device, comprising a frame, a first longitudinal beam and a second longitudinal beam installed in the middle of the frame, a carton platform installed between the middle of the first longitudinal beam and the middle of the head end frame of the frame, a carton conveyor belt installed between the middle of the two longitudinal beams, and a middle crossbeam installed between the middle of the second longitudinal beam and the middle of the end frame of the frame; a lifting and moving device is installed on the top of the frame, the device comprising a gear box and an axle seat installed at both ends of the top of the frame, a chain is provided between the driving gear of the gear box and the driven gear on the axle seat, a straight track is also installed on the top of the frame, and also includes a top crossbeam fixed with the chain, rollers rolling along the track are installed at both ends of the top crossbeam, and a motor driving the gear box is also installed on the top of the frame; a lifting cylinder is installed below the middle of the top crossbeam, and a bottle clamping and moving device is installed at the bottom end of the piston rod of the lifting cylinder; a bottle feeding device is installed on the middle crossbeam.

[0004] This invention provides a cartoning machine with a simple and reasonable structural design. By arranging a carton platform and a carton conveyor belt in the middle of the cartoning machine, convenient supply of cartons to the cartoning machine and rapid transfer of cartons after packing are achieved. In actual operation, only one employee is required to open the carton and place it on the carton platform, and push the carton onto the carton conveyor belt after the carton on the carton conveyor belt is transferred. This saves more manpower than existing cartoning machines. By arranging a lifting mobile device that can move laterally on the top of the frame, a bottle clamping mobile device under the lifting mobile device, and a bottle feeding device on the middle crossbeam, the entire process of bottle feeding, bottle clamping movement, lifting movement, and packing is automated, with a high degree of automation. This cartoning machine uses a lifting mobile device, a bottle clamping mobile device, and a bottle feeding device to replace the existing manipulator, thereby reducing the cost of the entire machine.

[0005] However, there is an obvious shortcoming in this invention: there is a lack of a mechanism to flip the four hinges outward. During the packing process, the four hinges are in a free state, which makes it easy for the hinges to close inward, thus interfering with the normal packing of the robot arm and reducing the packing efficiency.

[0006] Therefore, there is an urgent need for a packaging box opening mechanism and a packing device for realizing a flip opening of the folded pages and improving the packing efficiency. Utility Model Content

DETAILED DESCRIPTION

[0033] The present invention will be described clearly and completely below with reference to the embodiments.

[0034] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0035] In the description of the embodiments, unless otherwise specified or limited, the terms "disposed" and "connected" should be understood broadly. For example, they can refer to fixed, removable, or integral connections; mechanical or electrical connections; direct connections, connections through an intermediary medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on their specific circumstances.

[0036] See attached Figure 1 , shown is the specific structure of the packing box, wherein the packing box is provided with a box body 1, and the port of the box body 1 is provided with four hinges 2. When packing, the four hinges 2 need to be flipped outward to increase the opening area at the port of the box body 1 to facilitate packing. Therefore, the utility model proposes a packing box opening mechanism and a packing device.

[0037] Example 1

[0038] See attached Figure 2-6 , shown is a packaging box opening mechanism, including a crossbeam 3, one end of the crossbeam 3 is fixed with a connecting arm 4 by bolts, the connecting arm 4 is a cylindrical structure, and one end is provided with a flange connection plate, the other end of the connecting arm 4 is horizontally connected to a guide arm 6 through a flange connection plate, a nut seat 9 is provided in the middle of the guide arm 6, a screw 10 is provided in the nut seat 9, one end of the screw 10 is provided with a handwheel 11, the other end of the screw is rotatably provided with a slide 8, and the guide arm 6 is provided with guide holes at both ends of the screw 10, a guide rod 7 is provided in the guide hole, when in use, the screw 10 is rotated by the handwheel 11, and the screw 10 drives the slide 8 to move up and down along the guide hole, and the lifting of the slide 8 can be applied to the opening of packaging boxes of different heights;

[0039] The slide 8 is provided with a T-shaped slider 12 along the length direction, and the slide 8 is symmetrically slidable with two slides 13 through the T-shaped slider 12. The slide 13 is provided with a mounting arm 14 perpendicular to the length direction of the slide 8. The top of the mounting arm 14 is hinged with a driving cylinder 15, which is specifically a pneumatic cylinder. The output end of the driving cylinder 15 is connected to a connecting rod 16, and a driving rod 17 is clamped on the connecting rod 16. One end of the driving rod 17 is rotatably connected to the slide 13. When the driving cylinder 15 controls the extension and retraction of the output end, the driving rod 17 is rotated forward and reversely through the connecting rod 16. A fixing surface 18 is provided on the opposite side of the two driving rods 17. Adjustment threaded holes 19 are equidistantly provided on the fixing surface 18. The driving rod 17 is bolted to an opener 20 through the adjustment threaded holes 19.

[0040] The opener 20 is provided with a first opening plate 21, and the end of the first opening plate 21 away from the lever 17 is inclined relative to the end close to the lever 17 to form a hypotenuse, and the hypotenuse is close to the end of the box body 1. The first opening plate 21 is inclined along the hypotenuse to provide a second opening plate 22, and the second opening plate is inclined in the direction of the hinge turning outward. The angle between the first opening plate 21 and the second opening plate 22 is 120 degrees. When opening, the output end is extended by the driving cylinder 15 to drive the lever 17 to drive the opener 20 to approach the hinge 2. At this time, the first opening plate 21 is used to press the opposite hinge 2 to turn it outward, and the outward-turned second opening plate 22 is used to turn the adjacent hinge 2 outward.

[0041] At the same time, during the opening process, since the second opening plate 22 is arranged along the oblique edge of the first opening plate 21, the oblique edge can make the distance between one end of the two openers 20 smaller than the distance between the two corresponding hinges 2, so that the entire opener 20 is gradually inserted between the four hinges 2 when rotating to open, achieving a purpose of gradual introduction, and preventing the problem of the first opening plate 21, the second opening plate 22 and the corresponding hinge 2 from colliding head-on;

[0042] At the same time, by using the equally spaced adjustment threaded holes 19, the distance between the two hinges 2 can be adjusted when opening, so as to be suitable for boxes 1 of different sizes.

[0043] It can be seen that when packing, the driving cylinder 15 controls the lever 17 to drive the opener 20 to flip the four hinges 2 of the box body 1 outward, preventing the hinges 2 from shrinking inward during packing, increasing the opening area of the port of the box body 1, facilitating packing, and improving work efficiency.

[0044] When in use, the position of the slide 8 is adjusted by the lead screw 10 according to the total height of the packaging box, so that the lowest end of the opener 20 is located above the hinge 2 to avoid interference with the hinge 2. At the same time, the distance between the two openers 20 is adjusted according to the distance between the two opposite hinges 2 on the packaging box. Then the packaging box enters from the entrance 37 of the conveyor 36, and then the conveyor 36 uses the first push plate 39 to push the packaging box between the two levers 17, and then starts the drive cylinder 15 to use the connecting rod 16 to drive the lever 17 to rotate, and the lever 17 further drives the opener 20 to make a circular motion in the direction of the hinge 2. When the opener 20 approaches the hinge 2, the first opening plate 21 and the second opening plate 22 are used to press the two adjacent hinges 2 outward to achieve the opening flip, and then the robot arm 5 cooperates with the suction cup 34 to put the product into the box body 1. Finally, after the boxing is completed, the second push plate 40 on the conveyor 36 is used to push the packaging box out from the exit 38 to the next conveyor line.

[0047] Furthermore, a synchronous belt 33 is wound around the first drive wheel 26, the second drive wheel 27, the first auxiliary wheel 30, the second auxiliary wheel 31 and the third auxiliary wheel 32. The two ends of the synchronous belt 33 are respectively fixed to the two sides of the robot arm 5. In this way, when in use, the first drive motor 28 and the second drive motor 29 use the synchronous belt 33 to realize the lateral and longitudinal movement of the robot arm 5, and cooperate with the suction cup 34 to realize the placement of the product into the box body 1.

[0048] Example 3

[0049] See attached Figure 8 , as shown, the difference from the first embodiment is that the connection method between the lever 17 and the opener 20 is different. In the third embodiment, the lever 17 is an optical axis, and the opener 20 is provided with a sleeve 201 near one end of the lever 17. The sleeve 201 is fitted with the lever 17, and the sleeve 201 is provided with a threaded hole at the position of the lever 17. When adjusting the distance between the two openers 20, the sleeve 201 slides on the lever 17, and the threaded hole and the bolt are used to cooperate to achieve the fixation of the position of the opener 20 on the lever 17.

[0050] The above description is only a preferred specific embodiment of the present invention and does not limit the scope of protection of the present invention.
