Technical Field
[0001] This utility model relates to the field of cardboard box production equipment technology, and in particular to an automatic board feeding device for cardboard box printing. Background Technology
[0002] Printing is one of the key processes in cardboard box production. Before being fed into the printing press, cardboard boards need to be accurately and smoothly transported and positioned to ensure the positional accuracy and consistent quality of the printed pattern. Traditional board feeding devices typically use fixed support platforms and guiding mechanisms, with relatively fixed structures and dimensions, and are mainly suitable for single or fixed-size cardboard boards.
[0003] With the development of the packaging industry, cardboard box products are becoming increasingly diversified, produced in small batches, and available in multiple specifications. This necessitates that the board feeding device possess excellent dimensional adaptability, enabling it to quickly and accurately position and feed cardboard boxes of varying lengths and widths. Existing board feeding devices often suffer from the following problems when dealing with dimensional changes: First, the positioning mechanism is inconvenient to adjust, making it difficult to quickly adapt to cardboard boxes of different sizes. This results in long downtime and adjustment periods when changing production specifications, impacting production efficiency. Second, for smaller or special-sized cardboard boxes, conventional support and baffle structures may not provide effective positioning, easily leading to offset, tilting, or misalignment, affecting the registration accuracy of subsequent printing. Third, the feeding process lacks continuity; the board picking and placing actions are not smoothly integrated with the conveying process, making it difficult to achieve high-speed, continuous automated feeding and restricting the production cycle of the entire printing unit. Utility Model Content
[0004] To overcome the problems of existing board feeding devices being unable to quickly adapt to different sizes of cardboard, having low positioning accuracy, and being unable to achieve continuous and efficient automated feeding, this utility model provides a cardboard printing board feeding device. Through an adjustable baffle mechanism, lifting cooperation, and two sets of alternating suction cups, it achieves rapid positioning and accurate, stable, and continuous automated feeding of cardboard boards of different sizes.
[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: a cardboard board printing and feeding device, including a frame; a board base, which is set in the middle of the frame through a lifting mechanism for supporting cardboard boards; multiple baffles arranged around the board base for supporting the edges of the cardboard boards; a driving mechanism, which is set on the frame and connected to the baffles for driving the baffles to move to adjust the positioning spacing of the cardboard boards; a conveyor belt, which is arranged on one side of the frame for conveying cardboard boards; a suction cup, which is arranged on the movement path from the board base to the conveyor belt for picking up and placing cardboard boards; and a moving mechanism, which is set on the frame and connected to the suction cup for driving the suction cup to move and rise and fall between the board base and the conveyor belt.

[0008] The aforementioned cardboard printing feeding device includes a drive mechanism comprising a belt arranged below the frame, two pulleys connected to the belt, and a second motor that drives one of the pulleys to rotate. The belt is connected to the baffle.
[0009] In the aforementioned cardboard printing and feeding device, the frame is provided with a slide rail, and the bottom of the baffle is provided with a slider that slides in cooperation with the slide rail.
[0010] In the aforementioned cardboard printing and feeding device, the driving mechanism consists of two sets, each driving two opposing baffles.
[0011] In the aforementioned cardboard printing and feeding device, the plate holder has grooves around its perimeter for the baffle to extend into.
[0012] The aforementioned cardboard printing feeding device includes a moving mechanism comprising a suspension supporting the suction cup, a first cylinder driving the suspension to rotate horizontally, and a second cylinder driving the first cylinder to move up and down.

[0027] This invention provides a cardboard board printing feeding device, aiming to solve the problems of difficulty in quickly adapting to cardboard boards of different sizes, inaccurate positioning, and insufficient continuous feeding in the existing technology. This device can achieve precise positioning and continuous automated feeding of cardboard boards of various specifications.
[0028] like Figure 1-6 As shown, the carton board printing and feeding device mainly includes a frame 1, a lifting mechanism 6, a board base 2, a drive mechanism 7, a baffle 3, a conveyor belt 4, a suction cup 5, and a moving mechanism 8.
[0029] The platform 1 constitutes the main support structure of the device. At the center of the platform 1, a support plate 2 for supporting stacked cardboard boxes is provided via a lifting mechanism 6. The lifting mechanism 6 specifically comprises a screw 61 threadedly connected to the platform 1. One end of the screw 61 is rotatably connected to the support plate 2 via a bearing seat, and the other end is connected to a first motor 62 via a coupling. Guide rods 63 are arranged around the first motor 62, penetrating the platform 1. A threaded sleeve that mates with the screw 61 is fixedly installed on the platform 1. When the first motor 62 drives the screw 61 to rotate, due to the threaded engagement between the screw 61 and the threaded sleeve, the screw 61, along with the first motor 62, will generate linear motion relative to the platform 1, thereby lifting or lowering the support plate 2 connected to one end of the screw 61. During the linear motion with the first motor 62, the guide rod 63 slides with a sliding sleeve provided on the upper part of the platform 1, playing a guiding role in preventing circumferential displacement of the first motor 62 and ensuring stable movement.
[0030] Around the base 2, baffles 3 are provided via a drive mechanism 7 to support and clamp the edges of the cardboard boxes. The drive mechanism 7 is specifically constructed as follows: it includes a belt 71 positioned below the frame 1, connected to the baffles 3. Both ends of the belt 71 are covered with pulleys 72 rotatably connected to the frame 1. A second motor 73 is installed below the frame 1, driving one of the pulleys 72. When the second motor 73 operates, it drives the pulley 72 to rotate, thereby moving the belt 71 and causing the baffles 3 connected to the belt 71 to move linearly. To ensure the smooth movement of the baffles 3, a slide rail 74 is provided on the upper part of the frame 1, and a slider 75, capable of linearly sliding along the surface of the slide rail 74, is installed below the baffles 3. The slider 75 forces the baffles 3 to move strictly along the direction set by the slide rail 74. Preferably, the drive mechanism 7 is configured in two sets, with each set driving two opposing baffles 3. The distance between the two opposing baffles 3 constitutes the positioning distance for the cardboard board, which can effectively prevent the cardboard board from tilting during stacking or positioning. In addition, grooves are provided around the board base 2 to accommodate the entry and exit of the baffles 3. When processing cardboard boards smaller than the board base 2, the baffles 3 can extend into the grooves, thereby achieving effective edge positioning and support for small boards.
[0031] A conveyor belt 4 is arranged on one side of the stand 1 to transport the positioned cardboard boxes to the next process (such as a printing machine). The process of transferring the cardboard boxes from the stand 2 to the conveyor belt 4 forms a movement path.
[0032] Along this movement path, suction cups 5 are arranged for picking up and placing cardboard boxes. The suction cups 5 are driven by a moving mechanism 8 to achieve their movement. The moving mechanism 8 specifically comprises: a suspension 81 supporting multiple suction cups 5. Above the suspension 81 is a first cylinder 82 that drives its movement; this first cylinder 82 is preferably a rotary cylinder, capable of driving the suspension 81 and the suction cups 5 thereon to rotate horizontally in the area between the plate seat 2 and the conveyor belt 4. To control the vertical movement of the suction cups 5, support rods 84 are arranged at intervals on the upper part of the platform 1, with support plates 85 placed horizontally between the support rods 84. A second cylinder 83, preferably a telescopic cylinder, is installed on the support plate 85 to drive the first cylinder 82 to lift and lower. The second cylinder 83 can drive the first cylinder 82, the suspension 81, and the suction cups 5 as a whole to lift and lower vertically, thereby allowing the suction cups 5 to descend above the plate seat 2 to pick up cardboard boxes, or to rise to a certain height for transfer.
[0033] To further optimize production efficiency, two sets of suction cups 5 are spaced apart on the suspension 81. These two sets of suction cups 5 can work alternately. When one set of suction cups 5 picks up the cardboard at the board holder 2, the other set of suction cups 5 can simultaneously perform the action of putting down the cardboard at the conveyor belt 4. This cycle is repeated to achieve continuous operation of picking up and putting down the cardboard, greatly reducing waiting time.
[0034] The operating method of this device is as follows: Initial preparation and placement of cardboard: Start the device, the second cylinder 83 is activated, driving the suction cup 5 and its suspension 81 to rise to a higher position, making room above the board holder 2. The operator or the equipment of the previous process places a stack of cardboard to be printed on the board holder 2.
[0035] Cardboard board positioning: Based on the current size of the cardboard board, the second motor 73 is controlled to operate. The second motor 73 drives the four side baffles 3 to move synchronously towards the center through pulleys 72 and belt 71 until the inner sides of all baffles 3 contact the edge of the cardboard board stack, completing the circumferential positioning and clamping of the entire stack of cardboard boards to prevent them from shifting or tilting. If the cardboard board size is small, the baffles 3 can partially extend into the grooves around the board base 2 for support.
[0036] Top cardboard pickup: The first motor 62 of the lifting mechanism 6 starts, driving the screw 61 to rotate, lifting the board base 2 and the entire stack of cardboard boxes on it to a certain height, ensuring that the topmost cardboard box is in a position easy to pick up. Then, the moving mechanism 8 begins to work: the second cylinder 83 drives the suction cups 5 to descend, causing a set of suction cups 5 on the suspension 81, which are in a ready state, to contact and adhere to the topmost single cardboard box. After the adhesion is secure, the second cylinder 83 drives the suction cups 5 and the cardboard box to rise.
[0037] Cardboard board transfer and placement: The first cylinder 82 (rotary cylinder) actuates, driving the suspension 81 and the suction cup 5 holding the cardboard board to rotate horizontally, moving it from above the board holder 2 to above the conveyor belt 4. Then, the second cylinder 83 actuates again, driving the suction cup 5 to descend, smoothly releasing the cardboard board to the designated position on the conveyor belt 4. After release, the suction cup 5 rises.
[0038] Continuous cyclic operation: After the first set of suction cups 5 completes the placement of a cardboard board and rises, the first cylinder 82 drives the suspension 81 to rotate in the opposite direction, returning it to above the board holder 2. Simultaneously, another set of suction cups 5 on the suspension 81 (which may have completed picking up a board in the previous cycle or is in a ready position) can synchronously perform the next picking or placing operation. Under the control of the lifting mechanism 6, the board holder 2 rises by one board thickness each time a cardboard board is removed, always keeping the topmost cardboard board in a ready-to-pick position. This cycle continuously and automatically achieves the precise transfer of single cardboard boards from the board holder 2 to the conveyor belt 4.
[0039] Adaptable to different sizes: When it is necessary to change to cardboard boxes of different sizes, simply adjust the position of the four side baffles 3 to the new positioning distance via the drive mechanism 7. At the same time, the motion parameters of the lifting mechanism 6 and the moving mechanism 8 can be adjusted as needed, allowing for quick adaptation to the production of new specifications. The setup time is short and the flexibility is high. Through the above structure and method, this utility model achieves high-precision, high-efficiency, and continuous automatic feeding of cardboard boxes of various sizes, effectively improving the flexibility and overall efficiency of the cardboard printing production line.
