Description

Technical Field

[0001] This invention relates to the field of cardboard box production, and more particularly to an automatic packaging device for cardboard box production. Background Technology

[0002] As one of the most basic carriers in modern logistics, warehousing, and product packaging, the demand for cardboard boxes continues to grow with the booming development of e-commerce and manufacturing. In the cardboard box production line, packaging is the final and crucial process, and its efficiency and quality directly affect the product's delivery speed, transportation safety, and corporate image.

[0003] However, most current cardboard box packing devices use strapping machines to directly bundle stacks of finished cardboard boxes. Because the cardboard boxes lack effective compression during the strapping process, the edges of the cardboard boxes are not neat enough, which can easily lead to the bundled cardboard boxes being relatively loose. This can cause the cardboard boxes to shift or deform during subsequent transportation, affecting the packing quality. Summary of the Invention

[0004] In view of the shortcomings or deficiencies of the prior art, the present invention provides an automatic packaging device for carton production, which can neaten the edges of the finished carton and press the finished carton before bundling, thereby making the finished carton more tightly bundled and less prone to loosening, resulting in better bundling and packaging effect.

[0005] The technical implementation of the present invention is as follows: an automatic packaging device for carton production includes a strapping machine, a plurality of conveying rollers are rotatably connected to the strapping machine, and finished cartons are placed on the plurality of conveying rollers. Two fixing bolts are fixedly connected to the strapping machine, and mounting brackets are slidably connected to the two fixing bolts.

[0006] More preferably, it also includes a gathering mechanism, which is disposed on the mounting slide. The gathering mechanism includes sliders, and four sliders are slidably connected to the strapping machine. Two sliders located on the same side of the strapping machine form a group. The mounting slide is slidably connected to the two sliders in the same group. A return spring is connected between the mounting slide and the two sliders in the same group. Sliding columns are slidably connected to both mounting slides. Two sliding columns located on the same mounting slide form a group. The sliding columns are fixedly connected to the sliders. Push frames are fixedly connected to all four sliding columns. The finished carton is located between the four push frames. Sliding rod frames are slidably connected between the strapping machine and the two fixing bolts. The sliding rod frames are fixedly connected to the mounting slide. Arc-shaped rods are fixedly connected to the ends of the two sliding rod frames that are close to each other. A servo motor is fixedly connected to the top of the strapping machine, and a rotating slot is rotatably connected to the top of the strapping machine.

[0007] More preferably, the rotating disk has two guide grooves, and the bottom ends of the two arc-shaped rods are respectively located in the two guide grooves on the rotating disk.

[0008] More preferably, it also includes a pressing mechanism, which is disposed on the mounting slide. The pressing mechanism includes a lower pressing frame, and the lower pressing frame is slidably connected to each of the four slide columns. Two lower pressing frames located on the same side of the strapping machine form a group. The lower pressing frame is slidably connected to the push frame. A compression spring is connected between the lower pressing frame and the slide column. Two lower pressing frames in one group are slidably connected to two lower pressing frames in another group, respectively, with a lower pressing plate. The finished carton is located below the two lower pressing plates. An extrusion plate is fixedly connected to each of the four lower pressing frames. Both ends of the extrusion plate are provided with protruding rods. Two inclined slot frames are fixedly connected to each of the two mounting slides. Two inclined slot frames located on the same mounting slide form a group.

[0009] More preferably, each of the inclined slot frames has two extrusion slots, and the two protrusions on the extrusion plate are respectively located in the two extrusion slots on the inclined slot frame.

[0010] More preferably, it also includes an edge-trimming mechanism, which is mounted on the strapping machine. The edge-trimming mechanism includes baffles, and two baffles are rotatably connected to the strapping machine. A torsion spring connects the strapping machine to both baffles. One-way bearings are provided at the bottom of both baffles. A support column is fixedly connected to the bottom of one of the one-way bearings, and a flipping gear is fixedly connected to both the other one-way bearing and the support column. Slide strips are fixedly connected to both mounting slides, and the strapping machine is slidably connected to both slide strips. A flipping rack is fixedly connected to both slide strips, and the flipping gear meshes with the flipping rack. Two push plates are rotatably connected to the strapping machine.

A drive rack is fixedly connected to both slide strips, and the transmission gear meshes with the drive rack.

[0011] Compared with the prior art, the present invention has the following advantages: When the finished carton is located under the two lower pressure plates, the servo motor drives the four push frames to push the edge of the finished carton together, so that the edge of the finished carton is aligned. Then, the two lower pressure plates move downward and together with the four lower pressure frames press the finished carton tightly. At this time, the strapping machine will strap the finished carton together. Then, the servo motor drives the two lower pressure plates and the four push frames to disengage from the finished carton, thereby completing the strapping and packaging of the finished carton. In this way, the edge of the finished carton can be neatly arranged, and the finished carton can be pressed before strapping, so that the finished carton is strapped more tightly and is not easy to loosen, resulting in a better strapping and packaging effect.

[0012] When the two sliding rods drive the two mounting carriages to move closer to each other, the two push plates and the two baffles work together to neatly tidy the edges of the finished carton, thus improving the bundling and packaging effect. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Example 1

[0024] An automatic packaging device for cardboard box production, such as Figures 1-8 As shown, it includes a strapping machine 1, on which several conveyor rollers 2 are rotatably connected, and on which finished cardboard boxes 21 are placed, and two fixing bolts 3 are fixedly connected to the strapping machine 1, and each of the two fixing bolts 3 is slidably connected to a mounting bracket 4.

[0025] It also includes a gathering mechanism, which is mounted on the mounting slide 4. The gathering mechanism includes sliders 51. Four sliders 51 are slidably connected to the strapping machine 1. Two sliders 51 located on the same side of the strapping machine 1 form a group. The mounting slide 4 is slidably connected to two sliders 51 in the same group. A return spring 52 is connected between the mounting slide 4 and the two sliders 51 in the same group. Sliding columns 53 are slidably connected to both mounting slides 4. Two sliding columns 53 located on the same mounting slide 4 form a group. 3 is fixedly connected to the slider 51. Each of the four sliding columns 53 is fixedly connected to a pusher frame 54. The finished carton 21 is located between the four pusher frames 54. The four pusher frames 54 are used to tidy up the edges of the finished carton 21. The strapping machine 1 is slidably connected to the two fixing bolts 3 by a sliding rod frame 55. The sliding rod frame 55 is fixedly connected to the mounting slide 4. The ends of the two sliding rod frames 55 that are close to each other are fixedly connected to an arc-shaped rod 56. A servo motor 57 is fixedly connected to the top of the strapping machine 1. A rotating groove plate 58 is rotatably connected to the top of the strapping machine 1.

[0026] The rotating disk 58 has two guide grooves, and the bottom ends of the two arc-shaped rods 56 are respectively located in the two guide grooves on the rotating disk 58.

[0027] It also includes a pressing mechanism, which is mounted on the mounting slide 4. The pressing mechanism includes a lower pressing frame 61, which is slidably connected to each of the four sliding columns 53. Two lower pressing frames 61 located on the same side of the strapping machine 1 form a group. The lower pressing frame 61 is slidably connected to the push frame 54. A compression spring 62 is connected between the lower pressing frame 61 and the sliding column 53. Two lower pressing frames 61 in one group are slidably connected to two lower pressing frames 61 in another group, respectively, with a lower pressing plate 621. The finished carton 21 is located below the two lower pressing plates 621. The two lower pressing plates 621 are used to press the finished carton 21 together with the two groups of lower pressing frames 61. Each of the four lower pressing frames 61 is fixedly connected to a squeezing plate 63. Both ends of the squeezing plate 63 are provided with protruding rods. Two inclined slot frames 64 are fixedly connected to each of the two mounting slides 4. Two inclined slot frames 64 located on the same mounting slide 4 form a group.

[0028] Each inclined slot frame 64 has two extrusion slots, and the two protrusions on the extrusion plate 63 are respectively located in the two extrusion slots on the inclined slot frame 64.

[0029] Initially, this equipment is connected to a conveyor system. First, the conveyor system transports a certain number of stacked cardboard boxes 21 onto several conveyor rollers 2. When the cardboard boxes 21 are located below the two lower pressure plates 621, the servo motor 57 drives the rotating tray 58 to rotate. The rotation of the rotating tray 58 compresses the two arc-shaped rods 56, causing them to move closer to each other. The movement of the two arc-shaped rods 56 causes the two sliding rod frames 55 to move closer to each other. The movement of the two sliding rod frames 55 causes the two mounting slide frames 4 to move closer to each other. The movement of the two mounting slide frames 4 causes the two sets of sliders 51, the two sets of inclined tray frames 64, and the two sets of sliding columns to move closer to each other. Both sets of slide columns 53 move towards each other, causing the four push frames 54 to move towards each other. The four push frames 54 together push the edges of the finished carton 21, aligning the edges of the finished carton 21. When the slide columns 53 can no longer move and come into contact with the strapping machine 1, the two mounting slide frames 4 will each drive the two sets of inclined slot frames 64 to continue moving towards each other. The return spring 52 will be compressed, and the two sets of inclined slot frames 64 will press the four pressing plates 63 downward. The downward movement of the pressing plates 63 will drive the lower pressing frame 61 downward, compressing the compression spring 62. The downward movement of the two sets of lower pressing frames 61 will each drive the two... The lower pressure plate 621 moves downwards, and the two lower pressure plates 621, together with the four lower pressure frames 61, press the finished carton 21 tightly. At this time, the strapping machine 1 will bundle and pack the finished carton 21. Then, the servo motor 57 will drive the two arc-shaped rods 56, the two sliding rod frames 55, the two mounting slides 4, and the two sets of inclined slot frames 64 to move in a direction away from each other. The return spring 52 will return to its original position, and the inclined slot frame 64 will no longer press the pressure plate 63. The compression spring 62 will return to its original position, and the return of the compression spring 62 will drive the lower pressure frame 61, the pressure plate 63, and the lower pressure plate 621 to move upwards and return to their original positions. The finished carton 21 will then disengage from the two lower pressure plates 621. Next, the two sets of mounting carriages 4 will drive the two sets of sliders 51 and the two sets of sliding columns 53 to move and reset in a direction away from each other. The reset of the two sets of sliding columns 53 will drive the four push frames 54 to reset in a direction away from each other. The finished carton 21 will disengage from the four push frames 54, thereby completing the bundling and packaging of the finished carton 21. Finally, the conveying equipment will drive several conveying rollers 2 to convey and unload the packaged finished carton 21. In this way, the edges of the finished carton 21 can be neatened, and the finished carton 21 can be pressed before bundling, so that the finished carton 21 is bundled more tightly and is not easy to loosen, resulting in a better bundling and packaging effect.

[0030] Example 2

[0031] Based on Example 1, such as Figures 1-4As shown, it also includes an edge-trimming mechanism, which is mounted on the strapping machine 1. The edge-trimming mechanism includes a baffle 71. Two baffles 71 are rotatably connected to the strapping machine 1. Torsion springs 72 are connected between the strapping machine 1 and the two baffles 71. One-way bearings 73 are provided at the bottom of each of the two baffles 71. A support column 731 is fixedly connected to the bottom of one of the one-way bearings 73. A turning gear 74 is fixedly connected to both the other one-way bearing 73 and the support column 731. Sliding strips 75 are fixedly connected to both of the mounting slides 4. The strapping machine 1 is slidably connected to both sliding strips 75. A fixed flip rack 76 is provided, and the flip gear 74 meshes with the flip rack 76. Two push plates 77 are rotatably connected to the strapping machine 1. The two push plates 77 are used to cooperate with two baffles 71 to tidy up the two sides of the finished carton 21. One of the push plates 77 is fixedly connected to a connecting shaft 771, and the other push plate 77 and the connecting shaft 771 are both fixedly connected to a transmission gear 78. Two mounting slides 4 are fixedly connected to two slides 79. The strapping machine 1 is slidably connected to the two slides 79. A drive rack 710 is fixedly connected to the two slides 79, and the transmission gear 78 meshes with the drive rack 710.

[0032] When the finished carton 21 is conveyed onto several conveyor rollers 2, one edge of the finished carton 21 will contact two baffles 71. When the two slide rails 55 drive the two mounting slides 4 to move towards each other, the mounting slides 4 will drive slide bar 1 75 and slide bar 2 79 to move. The movement of the two slide bars 1 75 will drive the two rotating racks 76 to move. The rotating racks 76 will mesh with the rotating gear 74. The movement of the rotating racks 76 will drive the rotating gear 74 to rotate. Under the action of the one-way bearing 73, the rotating gear 74 rotates. The baffle 71 will not rotate. Immediately afterwards, the flip rack 76 will disengage from the flip gear 74. Simultaneously, the movement of the two slide bars 79 will cause the two drive racks 710 to move. The two drive racks 710 will drive the two transmission gears 78 to rotate. The rotation of the two transmission gears 78 will cause the two push plates 77 to rotate in a direction closer to each other. Both push plates 77 will contact the other edge of the finished carton 21. The two push plates 77 will cooperate with the two baffles 71 to neatly align the two sides of the finished carton 21. When the two slide bars 55 respectively... When the two mounting slides 4 move away from each other, the mounting slides 4 will cause slide bar 1 75 and slide bar 2 79 to move in the opposite direction. The reverse movement of slide bar 1 75 will cause the two rotating racks 76 to move in the opposite direction respectively. The rotating racks 76 will re-engage with the rotating gear 74. The reverse movement of the rotating racks 76 will cause the rotating gear 74 to rotate in the opposite direction. The reverse rotation of the rotating gear 74 will cause the one-way bearing 73 and the baffle 71 to rotate, and the torsion spring 72 will be twisted. Then the rotating racks 76 will disengage from the rotating gear 74 again. Upon contact, the torsion spring 72 will reset. The reset of the torsion spring 72 will cause the baffle 71, the one-way bearing 73, and the flip gear 74 to rotate in the opposite direction and reset. At the same time, the reverse movement of the two slide bars 79 will cause the two drive racks 710 to move in the opposite direction. The reverse movement of the two drive racks 710 will cause the two transmission gears 78 to rotate in the opposite direction. The reverse rotation of the two transmission gears 78 will cause the two push plates 77 to rotate in a direction away from each other. In this way, the two sides of the finished carton 21 can be neatly arranged, further improving the bundling and packaging effect.
