Description

Technical Field

[0001] This utility model relates to the field of three-dimensional box forming machine technology, and in particular to a high-efficiency three-dimensional box forming machine with an improved structure. Background Technology

[0002] 3D boxes, also known as drawer boxes, are packaging containers used in various fields. They are widely used for the display, sales, and gift packaging of products such as food, medicine, toys, cosmetics, and stationery.

[0003] With the development of automated equipment, manual folding of three-dimensional boxes has been gradually abandoned in the production and processing process, and automated forming machines are used for production. For example, the three-dimensional box folding machine disclosed in Chinese patent CN221756972U can automatically feed paper and fold boxes. However, since the cardboard takes a certain amount of time to fold, after the cardboard is fed, it is necessary to wait for the previous cardboard to finish folding and discharge before the next cardboard can be fed. This will cause the cardboard to stay in the feeding mechanism for a long time, which not only results in low feeding efficiency, but also makes it easy for the adhesive on the cardboard to become less sticky, which is not conducive to production. In view of this, the inventor has made a new invention. Utility Model Content

Detailed Implementation

[0027] The following is in conjunction with the appendix Figures 1 to 7 This utility model will be described in detail.

[0028] This utility model discloses an improved high-efficiency three-dimensional box forming machine, comprising a frame 1. The frame 1 is sequentially equipped with a feeding mechanism 2, a folding mechanism 3, a pressing mechanism 4, and a retracting mechanism 5. The feeding mechanism 2 is equipped with a feed belt 21. Two sets of folding mechanisms 3 and pressing mechanisms 4 are respectively located on the left and right sides of the feed belt 21. The feeding mechanism 2 is equipped with a synchronous feeding device 22 that can reciprocate between the feed belt 21 and the two folding mechanisms 3. Paperboard is fed into the frame 1 via the feed belt 21. The synchronous feeding device 22 sequentially transports different paperboards to the two folding mechanisms 3 for folding and forming, significantly reducing the waiting time for paperboard feeding and increasing the feeding frequency and speed of the three-dimensional box forming machine.

[0029] Specifically, the synchronous feeding device 22 is equipped with a first linear track 23, on which two moving modules a24 are mounted. Each moving module a24 is equipped with a feeder 25 and a first cylinder 26 that drives the feeder 25 to move up and down. The feeder 25 is externally connected to a negative pressure adsorption device for loading and unloading cardboard boxes. The first cylinder 26 drives the feeder 25 to move up and down, performing the gripping and placing actions. In this design, one moving module a24 and the feeder 25 work together to grip the cardboard box and place it in the folding mechanism 3 on the left side of the feed belt 21. The other moving module a24 and the feeder 25 work together to grip the cardboard box and place it in the folding mechanism 3 on the right side of the feed belt 21. The two feeders 25 pick up materials sequentially to reduce the time the cardboard box spends waiting to be gripped and loaded on the feed belt 21.

[0030] More specifically, the center distance between the two feeders 25 corresponds to the center distance between the folding mechanism 3 and the feeding belt 21. The first linear track 23 is equipped with a first motor 27 that drives the two moving modules a24 to move synchronously along the first linear track 23. The two folding mechanisms 3 are spaced at the same distance from the feeding belt 21. The first motor 27 drives the two moving modules a24 to move at the same speed and in the same direction. When one feeder 25 moves downward and grabs the cardboard box on the feeding belt 21, the other feeder 25 moves downward and places the cardboard box on the folding mechanism 3. When one feeder 25 grabs the cardboard box and moves to the folding mechanism 3, the other feeder 25 moves from the other folding mechanism 3 to above the feeding belt 21. This action is repeated so that the synchronous feeding device 22 sequentially transports different cardboard boxes to the two folding mechanisms 3 for folding and forming, thereby increasing the feeding frequency and speed of the three-dimensional box forming machine.

[0031] The folding mechanism 3 is provided with a base 31. Push plate devices 32 are provided on both sides of the base 31 in a first direction, and a bottom sealing device 33 is provided on one side of the base 31 in a second direction. The pressing mechanism 4 is provided on the other side of the base 31 in the second direction, and the pressing mechanism 4 is provided with a pressing device 41 that can move up and down and back and forth. The cardboard is placed above the push plate devices 32, and the pressing device 41 presses the cardboard against the base 31 from top to bottom. Through the cooperation of the push plate devices 32 and the bottom sealing device 33, the cardboard is folded into shape.

[0032] In a specific embodiment, the shape of the cardboard box is as follows: Figure 7As shown. The pusher device 32 is equipped with a moving module b321 and an irregularly shaped pusher 322 movably connected to the moving module b321. A limiting plate 323 is provided on the top of the irregularly shaped pusher 322, and a first shovel plate 324 is provided above the moving module b321. The folding mechanism 3 is also equipped with a driving device that drives the two moving modules b321 to move closer or further apart. When the synchronous feeding device 22 places the cardboard box above the folding mechanism 3, cardboard boxes A1 and A3 respectively contact the two limiting plates 323. The pressure plate 41 presses down on cardboard box A2, causing the cardboard box to move downward. Under the limiting action of the limiting plate 323, cardboard boxes A1 and A3 fold upward. Then, the two moving modules b321 move closer to each other, causing the two first shovel plates 324 to contact and press down on cardboard boxes A4 and B1 respectively, so that cardboard box A4 contacts and adheres to cardboard box B1, and the side folding of the three-dimensional box is completed.

[0033] A fixed frame 11 is provided inside the frame 1. The fixed frame 11 is provided with a threaded rod 12. A second motor 13 is provided below the threaded rod 12. A threaded sleeve 325 that is threadedly connected to the threaded rod 12 is provided below the base 31. The second motor 13 drives the threaded rod 12, causing the base 31 to rise. When the cardboard is placed in the folding mechanism 3, point A2 of the cardboard abuts against the base 31. When the pressure plater 41 presses the cardboard down, the base 31 moves down synchronously, providing continuous support to point A2 of the cardboard. This prevents the cardboard from unexpectedly twisting, deforming, or breaking, thus improving its protective performance.

[0034] The bottom sealing device 33 is equipped with a positioning frame 331 mounted on the frame 1. A moving module c332 is mounted on the positioning frame 331. The moving module c332 has two second shovels 333 that can move closer to or further away from each other. A second cylinder 334 is located at the rear end of each second shovel 333. The moving module c332 also has limiting rollers 335 located below the two second shovels 333. During the side folding process of the three-dimensional box, after the cardboard boxes A1 and A3 are folded up, the two second cylinders 334 each drive the second shovels 333 to bend the cardboard boxes B2 and B3, facilitating bottom sealing.

[0035] The positioning frame 331 is equipped with a third cylinder 336 that drives the moving module c332 to move up and down. After the second shovel plate 333 bends the cardboard boxes B2 and B3, the third cylinder 336 drives the moving module c332 to rise, which in turn causes the limiting roller 335 to move upward. During the movement, the limiting roller 335 will lift and bend the cardboard box A5, so that the cardboard box A5 is simultaneously bonded to B2 and B3, and the bottom sealing of the three-dimensional box is completed.

[0036] The pressing mechanism 4 is provided with a vertical second linear track 42. A moving module d43 and a third motor 44 are mounted on the second linear track 42 to drive the moving module d43 to move along the second linear track 42. The pressing device 41 is mounted on the moving module d43. In this structure, the moving module d43 is driven by the third motor 44, which in turn causes the pressing device 41 to move up and down, facilitating the pressing device 41 to press and form the box.

[0037] The pressing mechanism 4 is further provided with a third linear track 45, on which a moving module e46 and a fourth motor 47 are provided to drive the moving module e46 along the third linear track 45. A second linear track 42 is provided on the moving module e46 and is perpendicular to the third linear track 45. The fourth motor 47 drives the moving module e46, thereby causing the presser 41 to move back and forth. After the folding and sealing of the three-dimensional box is completed, the third cylinder 336 drives the moving module c332 to descend, and the fourth motor 47 drives the presser 41 to move forward. The presser 41 pushes the three-dimensional box to the unloading mechanism 5, allowing the three-dimensional box to be discharged.

[0038] The unloading mechanism 5 is equipped with a discharge belt 51, which is located below the two bottom sealing devices 33 and extends outward from the frame 1. The unloading mechanism 5 is also equipped with a discharge device 52 for feeding the carton to the discharge belt 51. The stereo box is pushed to the discharge device 52 by the pressure device 41. Then, the discharge device 52 first fixes the stereo box, the pressure device 41 retracts and exits from the stereo box, and finally, the discharge device 52 delivers the stereo box to the discharge belt 51 for discharge.

[0039] More specifically, the discharge device 52 is equipped with a pressing block 53 that can press the stereo box against the discharge belt 51, and push blocks 54 are provided on both sides of the pressing block 53. The pressing block 53 is equipped with a fourth cylinder 55, and the push blocks 54 are equipped with a fifth cylinder 56. The fifth cylinder 56 drives the push blocks 54 to clamp and fix the stereo box, so that the presser 41 can be withdrawn from the stereo box; then the fourth cylinder 55 drives the pressing block 53 to press the stereo box down, while the fifth cylinder 56 drives the push blocks 54 to reset, so that the stereo box falls stably and accurately onto the discharge belt 51 for discharge.

[0040] The above description is only a preferred embodiment of this utility model. For those skilled in the art, based on the concept of this invention, there will be changes in the specific implementation methods and application scope. The content of this specification should not be construed as a limitation of this utility model. 。
