Description

Technical Field

[0001] The utility model relates to the field of carton production, in particular to a folding device for producing folding cartons. Background Art

[0002] Cartons are mostly produced as a whole. In the process of specific packaging operations, different folding operations are often performed on the size of the carton according to different requirements. Generally, corresponding folds are pressed on the surface of the cardboard to facilitate rapid molding during use. A carton folding device is disclosed in the Chinese utility model patent with announcement number CN219727354U. The pressing wheels on both sides of the device move closer or farther away from each other to change the indentation position, that is, the folding position changes. When the utility model performs indentation, the carton can be indented twice front and back under the action of the conveyor to deepen the indentation and prevent the indentation from being too shallow.

[0003] With respect to the above-mentioned related technologies, the inventor believes that there are the following defects: in the above-mentioned structure, the spacing between the two pressing wheels on the same threaded rod is fixed during adjustment, that is, they can only move inward or outward at the same time, and the spacing of the indentations on the carton is different according to different requirements, which makes it difficult to produce carton indentations of different widths and lengths. For this reason, we designed a folding device for folding carton production. Utility Model Content

[0006] As a further improvement of the above scheme, the mounting frame is formed with adjusting slide holes through the front and back, a lifting seat is arranged in the adjusting slide hole for sliding up and down, the mounting shaft rod is rotatably mounted in the lifting seat through a bearing, a threaded hole is provided at the upper end of the mounting frame, the bottom end of the threaded hole is connected with the adjusting slide hole, an adjusting screw rod is threadedly connected in the threaded hole, the bottom end of the adjusting screw rod is rotatably connected to the top of the lifting seat, the lifting seat can be moved up and down by rotating the adjusting screw rod, and then the first creasing wheel, the second creasing wheel and the limiting wheel can be moved up and down accordingly, so that cardboards of various thicknesses can be folded.

[0007] As a further improvement of the above scheme, a ball groove is provided above the lifting seat, a connecting ball is movably provided in the ball groove, the bottom end of the adjusting screw rod is welded to the upper surface of the connecting ball, the setting of the connecting ball enables the adjusting screw rod to rotate, and the lifting seat can also deflect forward and backward at the same time, when the front and rear adjusting screw rods are rotated respectively, a compensation effect can be played on the mounting shaft rod, so that it can deflect at a certain angle.

[0008] As a further improvement of the above scheme, two limiting wheels are movably arranged on the mounting shafts on the left and right sides of the creasing wheel one and the creasing wheel two, and a contact notch is formed by cutting away a portion in the middle of the outer ring surface of the limiting wheel, and the contact notch is located directly above the desired indentation of the cardboard below. The limiting wheel will not cause pressure contact on the indentation, and can prevent the two sides of the cardboard from warping up, and can also play a positioning role.

[0023] The mounting frame 3 is formed with an adjusting slide hole 31 through the front and back, and a lifting seat 32 is arranged in the adjusting slide hole 31 to slide up and down. The mounting shaft rod 5 is rotatably mounted in the lifting seat 32 through a bearing. A threaded hole is provided at the upper end of the mounting frame 3, and the bottom end of the threaded hole is connected to the adjusting slide hole 31. An adjusting screw rod 33 is threadedly connected in the threaded hole, and the bottom end of the adjusting screw rod 33 is rotatably connected to the top of the lifting seat 32. By rotating the adjusting screw rod 33, the lifting seat 32 can be moved up and down, and then the creasing wheel 1 6, the creasing wheel 2 7 and the limiting wheel 8 can be moved up and down accordingly, so that cardboards of different thicknesses can be folded.

[0024] A ball groove is provided above the lifting seat 32, and a connecting ball 34 is movably provided in the ball groove. The bottom end of the adjusting screw rod 33 is welded to the upper surface of the connecting ball 34. The setting of the connecting ball 34 enables the adjusting screw rod 33 to rotate, and the lifting seat 32 can also deflect forward and backward at the same time. When the front and rear adjusting screw rods 33 are rotated respectively, the mounting shaft rod 5 can be compensated so that it can deflect at a certain angle.

[0025] Two limiting wheels 8 are movably arranged on the mounting shafts 5 on the left and right sides of the creasing wheel 1 6 and the creasing wheel 2 7. A contact notch 81 is formed by cutting away a portion of the middle of the outer ring surface of the limiting wheel 8. The contact notch 81 is located just above the desired indentation of the lower cardboard. The limiting wheel 8 will not cause pressure contact on the indentation, and can prevent the two sides of the cardboard from warping up, and can also play a positioning role.

[0026] The mounting shaft 5 is slidably sleeved with a mounting sleeve 4, and the creasing wheel 1 6, the creasing wheel 2 7 and the limiting wheel 8 are rotatably mounted on the mounting sleeve 4 through bearings, and the mounting sleeve 4 is threadedly connected with a locking bolt, which is in close contact with the mounting shaft 5. The creasing wheel 1 6, the creasing wheel 2 7 and the limiting wheel 8 can move forward and backward on the mounting shaft 5, so that their positions can be adjusted according to needs, and thus they are suitable for cardboards of various sizes.

[0027] A guide rod 91 is installed on the left and right sides between the two support frames 1, and a guide plate 9 is horizontally arranged between the two guide rods 91. The guide plate 9 is designed to slide back and forth, and the bottom end of the guide plate 9 is 1-3mm above the conveying roller 2. Bolts are threadedly connected on the guide plate 9. After it slides back and forth, the bolts can be tightened to fix it. The guide plate 9 can block the front and back sides of the cardboard so that it will not be offset when it moves.

[0028] The implementation principle of a folding device for folding carton production in the embodiment of the present application is as follows: the rear ends of multiple conveying rollers 2 pass through the rear support frame 1 and are equipped with sprockets, and the multiple conveying rollers 2 are linked by sprockets and chains, and they are connected to the output shaft of an external driving device. In actual use, a cardboard with a crease is placed on the conveying roller 2, and then the positions of the creasing wheel 1 6, the creasing wheel 2 7, the limiting wheel 8, and the guide plate 9 are adjusted according to the cardboard. Specifically, after the cardboard with a crease is placed on the conveying roller 2, the two guide plates 9 are moved back and forth to make the guide plates 9 contact with the cardboard, and then the bolts are tightened, and then the multiple cardboards are rotated in sequence. The adjusting screw rod 33 on the mounting frame 3 and the front-rear moving limiting wheel 8, creasing wheel one 6, and creasing wheel two 7 make the outer ring surface of the limiting wheel 8 roll in contact with the upper surface of the cardboard, and the contact notch 81 on the limiting wheel 8 is placed above the indentation, and the creasing wheel one 6 and the creasing wheel two 7 are in the indentation, and then the locking bolt is fixed to complete the overall adjustment. When working, the cardboard is placed on the conveying roller 2, and the conveying roller 2 will move the cardboard from right to left. During the movement, it will pass through the creasing wheel two 7 and the creasing wheel one 6 in sequence, and then creases will be pressed on the cardboard below, so that it can be quickly folded (multiple folding processes are required according to different folds);

[0029] By arranging a creasing wheel 1 6 and a creasing wheel 2 7 above the conveying roller 2, both of which are fixed on the mounting shaft 5 through the mounting sleeve 4 and the locking bolt, the positions of which can be adjusted arbitrarily according to the needs, so that the cardboards of various sizes and positions can be creasingly operated, so that the cardboards can be folded quickly;

[0030] By arranging a limiting wheel 8 above the conveying roller 2, and a contact notch 81 is arranged on the limiting roller, and the contact notch 81 is located directly above the indentation, the limiting wheel 8 will not cause pressure contact on the indentation, and can prevent the two sides of the cardboard from warping up, and can also play a positioning role, thereby improving stability.

[0031] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
