Description

Technical Field

[0001] This utility model relates to the field of printing material cutting technology, and in particular to a material cutting device for color printing of cardboard boxes. Background Technology

[0002] Color box printing, as a key link in the modern packaging industry, is widely used in many fields such as food, medicine, electronics, and cosmetics. From customized packaging for exquisite gifts to bulk transport packaging for industrial products, color boxes not only achieve the visual presentation of brand image and clear transmission of product information through high-precision printing technology, but also need to take into account structural strength and cushioning performance to meet the needs of long-distance transportation.

[0003] Existing color box printing production lines still have significant shortcomings in the material unloading and palletizing process after printing. Currently, most qualified color boxes rely on manual labor to remove them one by one from the conveyor belt and stack them onto pallets. This process not only consumes a lot of manpower (a single production line requires 4-6 workers to operate continuously), but is also limited by the speed of manual operation, which seriously affects the efficiency of subsequent warehousing and logistics links, and has certain deficiencies. To address this, we propose a material unloading device for color printing on cardboard boxes. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a feeding device for color printing on cardboard boxes.

Vacuum suction cups are mounted at both ends inside the adjustment mechanism. The lifting mechanism is used to adjust the height of the vacuum suction cups to facilitate feeding the printed cardboard boxes. The adjustment mechanism is used to adjust the distance between the vacuum suction cups.

[0007] Preferably, the first slider is slidably connected to the first support frame, and the second slider is slidably connected to the second support frame.

[0008] Preferably, the lifting mechanism includes a movable frame fixed between a first slider and a second slider.

A second threaded post is threadedly connected inside the threaded sleeve. The second threaded post is inserted into the interior of the movable frame and connected to a movable plate. Movable posts are fixed at both ends of the top of the movable plate, and the movable posts pass through the movable frame and are slidably connected to it.

[0009] Preferably, the first bevel gear and the second bevel gear are meshing transmissions, the axial direction of the second threaded column is parallel to the axial direction of the movable column, and the adjusting mechanism is fixed to the bottom of the movable plate.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Reference Figure 1-3 A feeding device for color printing of cardboard boxes includes two sets of mounting plates 1. The mounting plates 1 are fixed to both sides of the printing conveyor belt by bolts. A first support frame 2 and a second support frame 6 are fixed to the two mounting plates 1 by bolts respectively. A first motor 3 is installed at one end inside the first support frame 2. A first threaded post 4 is installed on the output shaft of the first motor 3. A first slider 5 is threadedly connected to the first threaded post 4. A guide shaft 7 is fixed inside the second support frame 6. A second slider 8 is slidably connected to the guide shaft 7. The first slider 5 is slidably connected to the first support frame 2, and the second slider 8 is slidably connected to the second support frame 6. A lifting mechanism 9 is fixed between the first slider 5 and the second slider 8. An adjustment mechanism 10 is installed at the bottom of the lifting mechanism 9. Vacuum suction cups 11 are installed at both ends inside the adjustment mechanism 10. The lifting mechanism 9 is used to adjust the height of the vacuum suction cups 11 to facilitate the feeding of the printed cardboard boxes by the vacuum suction cups 11. The adjustment mechanism 10 is used to adjust the distance between the vacuum suction cups 11.

[0020] In one implementation, the lifting mechanism 9 adopts a precision structure of bevel gear transmission and threaded column engagement: the movable frame 91 is fixed between the first slider 5 and the second slider 8, and adjusts its horizontal position as the two move laterally; the second motor 93 inside the housing 92 drives the first bevel gear 94 to rotate, and drives the threaded sleeve 95 to rotate through the meshing second bevel gear 96, so that the second threaded column 97 can be smoothly raised and lowered along the axial direction, and simultaneously drive the movable plate 98 and the bottom adjustment mechanism 10 to move. The movable columns 99 at both ends of the movable plate 98 pass through the movable frame 91 and are slidably connected to ensure that there is no deviation during the lifting process, and realize the precise height control of the vacuum suction cup 11. It can not only adsorb the surface of the carton with constant pressure to avoid indentation, but also adapt to pallets with different stacking heights, providing stable vertical movement support for automated unloading.

[0021] As one implementation method, the adjustment mechanism 10 achieves flexible adjustment of the vacuum suction cup spacing through a reverse threaded column design: the mounting base 101 is fixed to the bottom of the movable plate 98, and the third motor 102 inside drives the third threaded columns 103 at both ends to rotate synchronously. Since the two threaded columns rotate in opposite directions, the third slider 104 performs symmetrical opening and closing movements within the mounting base 101, thereby quickly adjusting the lateral spacing of the vacuum suction cups 11. This structure does not require stopping the machine to change the clamps and can adapt to different carton sizes in a few seconds, significantly improving the device's compatibility with multi-variety orders, reducing manual intervention and production changeover losses. Combined with the stable adsorption function of the vacuum suction cups 11, it realizes full automation from carton gripping to palletizing, effectively solving the problems of low efficiency and poor accuracy of manual feeding in the prior art, and greatly improving the intelligence level and production efficiency of the printing production line.

[0022] The device is fixed to both sides of the printing conveyor belt via mounting plate 1. When it is necessary to unload and stack the printed cartons, the first motor 3 starts, and its output shaft drives the first threaded post 4 to rotate. The first threaded post 4 is threadedly connected to the first slider 5, causing the first slider 5 to slide along the first support frame 2. At the same time, the second slider 8 slides synchronously on the guide shaft 7, thereby adjusting the lateral position of the lifting mechanism 9 to ensure that the vacuum suction cup 11 at the bottom of the adjusting mechanism 10 is aligned with the cartons on the conveyor belt. The third motor 102 of the adjusting mechanism 10 starts, and its two output shafts drive the third threaded post 103 to rotate. Since the threads of the two third threaded posts 103 rotate in opposite directions, the third slider 104, which is threadedly connected to the third threaded post 103, moves relative to or away from each other within the mounting base 101, thereby adjusting the spacing between the vacuum suction cups 11 to accommodate cartons of different sizes. The second motor 93 of the lifting mechanism 9 starts. The output shaft drives the first bevel gear 94 to rotate, and the first bevel gear 94 meshes with the second bevel gear 96, driving the threaded sleeve 95 to rotate. The threaded sleeve 95 is threadedly connected to the second threaded post 97, causing the second threaded post 97 to move downward along the axial direction, driving the movable plate 98 to slide within the movable frame 91 through the movable post 99, thereby lowering the height of the vacuum suction cup 11. When the vacuum suction cup 11 contacts the surface of the carton, it adsorbs the carton through the vacuum system. Then, the second motor 93 rotates in the opposite direction, causing the second threaded post 97 to rise and lift the carton from the conveyor belt. When the carton is lifted to a suitable height, the first motor 3 operates again, driving the lifting mechanism 9 to move laterally above the palletizing tray. The second motor 93 controls the vacuum suction cup 11 to descend to the designated position on the tray, and the vacuum system is released, completing the carton stacking. The above actions are repeated to realize the automated gripping, height adjustment, spacing adjustment, and stacking process of the printed carton.

[0023] In summary, compared with the prior art, this utility model, by setting a first motor, a first threaded column, a first slider, a guide shaft, and a second slider, adjusts the lateral position of the lifting mechanism, allowing the vacuum suction cups to move on the conveyor belt and the palletizing tray. The adjusting mechanism adjusts the distance between adjacent vacuum suction cups, facilitating flexible adjustments according to the specifications of the cartons. At the same time, the lifting mechanism adjusts the height of the vacuum suction cups, removing the cartons from the conveyor belt and completing the palletizing on the tray. The device has a simple structure and very high palletizing efficiency, thereby improving the overall production efficiency of the production line.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
