Description

Technical Field

[0001] This utility model relates to the technical field of cardboard printing, and in particular to a cardboard printing feeding device. Background Technology

[0002] Cardboard is typically made from various plant fibers, sometimes with the addition of non-plant fibers, and is produced on a cardboard machine. When used for packaging, the cardboard needs to be printed to display various patterns to meet different packaging needs and effects. During the cardboard printing process, a feeding device is used to assist in feeding and improve printing efficiency. Existing technology publication number CN220886245U discloses a feeding device for a corrugated carton printing machine, including a machine body with a feeding trough inside. A conveyor belt is rotatably connected to one side of the machine body, and an ejector mechanism is located on one side of the conveyor belt inside the machine body. An upper dust removal mechanism is welded above the conveyor belt on the machine body, and a lower dust removal mechanism is fixedly installed at the lower end of the machine body. However, during transportation, it is inconvenient to correct the cardboard, affecting printing accuracy. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a paperboard printing feeding device that can restrict both sides of the paperboard, correct the paperboard, adjust the paperboard to a central position, facilitate printing after transportation, and improve printing accuracy.

[0004] This utility model discloses a cardboard printing feeding device, comprising a feeding platform, a base, a conveying component, a positioning component, a lifting component, and a feeding component. The bottom of the feeding platform is installed on the top of the base, the top of the feeding platform is installed with the lifting component, the top of the lifting component is installed with the feeding component, the right side of the lifting component is installed with the conveying component, and the top of the conveying component is installed with the positioning component. The cardboard is placed on the lifting component and pushed upward. The feeding component pushes the topmost cardboard to the right for feeding. The conveying component feeds the cardboard into the printing press. The positioning component restricts the two sides of the cardboard, corrects the cardboard, and adjusts it to a centered position, facilitating printing after transportation and improving printing accuracy.

[0005] Preferably, the lifting components include multiple columns, two crossbeams, two threaded rods, two lifting slides, two gearboxes, a dual-output motor, two lifting columns, and a lifting platform. The multiple columns are installed at the four corners of the top of the feeding platform. The crossbeams are located on the front and rear sides above the feeding platform and are installed on the top of the columns. Lifting columns are installed on the front and rear sides of the top of the feeding platform, with the lifting columns positioned between two columns. The top of the lifting columns is connected to the bottom of the crossbeams. Lifting grooves are provided inside the lifting columns. The threaded rods are rotatably installed within the lifting grooves, and the input end of the threaded rods is connected to the output end of the gearboxes. The dual-output motors are installed at the bottom of the feeding platform, with their front and rear output ends connected to the input end of the gearboxes. The lifting slides are slidably installed within the lifting grooves and are screwed onto the outer wall of the threaded rods. A lifting platform is installed between the two lifting slides. Placement slots are provided on the feeding platform and the lifting platform. A forklift places the cardboard onto the top of the lifting platform through the placement slots, improving the device's material changing efficiency. Starting the dual-output motors drives the threaded rods to rotate via the gearboxes. The threaded rods move the lifting slides within the lifting grooves, adjusting the position of the lifting platform and thus lifting the cardboard upwards.

[0006] Preferably, the feeding component includes two fixed plates, a rotating shaft, multiple rotating sleeves, multiple sets of elastic arc plates, and a feeding motor. The fixed plates are installed on the top of the crossbeam, and the rotating shaft is rotatably installed between the two fixed plates. The input end of the rotating shaft is connected to the output end of the feeding motor. Multiple rotating sleeves are installed on the outer wall of the rotating shaft, and multiple elastic arc plates are axially installed on the outer wall of the rotating sleeves. Rubber feet are provided at the ends of the elastic arc plates. When the feeding motor is started, the rotating shaft rotates, which in turn rotates the multiple rotating sleeves, which in turn rotate the multiple elastic arc plates, pushing the topmost cardboard to the right. This achieves automatic feeding of the cardboard, saving manpower and improving efficiency.

[0007] Preferably, the conveying component includes multiple feeding rollers and a transmission box. The multiple feeding rollers are rotatably mounted on the right end of two crossbeams. The transmission box is mounted on the rear side wall of the crossbeams. The input end of the feeding rollers is connected to the transmission box, and the input end of the transmission box is equipped with a conveying motor. When the conveying motor is started, it drives the multiple feeding rollers to move through the transmission box. After the paperboard moves to the right to the surface of the feeding rollers, it is fed into the printing press through the feeding rollers.

[0008] Preferably, the positioning component includes a fixed frame, a rotating rod, two adjusting blocks, an adjusting motor, two flared baffles, and two arc-shaped limiting plates. A fixed frame is installed on the top right side of the crossbeam, and an adjusting groove is opened on the top of the fixed frame. The rotating rod is rotatably installed in the adjusting groove, and threaded grooves are symmetrically opened at both ends of the rotating rod. The input end of the rotating rod is connected to the output end of the adjusting motor. The adjusting blocks are symmetrically slidably installed in the adjusting groove and screwed onto the outer wall of the rotating rod. A flared baffle is installed at the bottom of the adjusting block, and an arc-shaped limiting plate is installed on the inner wall of the flared baffle. When the cardboard moves on the feeding roller, the flared baffles on both sides can restrict the two sides of the cardboard, correcting the cardboard and adjusting it to a centered position for easy printing after transportation. At the same time, the arc-shaped limiting plates can prevent the two ends of the cardboard from warping, improving printing accuracy.

[0009] Preferably, it also includes two guide slide rods and two guide sliders. Guide slide grooves are provided on the left side walls of the two right-side columns, and the guide slide rods are installed in the guide slide grooves. Guide sliders are installed at the front and rear ends of the right side of the lifting platform. The guide sliders are slidably installed in the guide slide grooves and on the outer wall of the guide slide rods. When the lifting platform moves, it can drive the guide sliders to slide on the outer wall of the guide slide rods, providing guidance and support, improving structural strength, and ensuring stability during movement.

[0010] Preferably, it also includes two supporting diagonal braces. The supporting diagonal braces are installed on the outer wall of the right column, and the other end of the supporting diagonal braces is connected to the bottom right side of the crossbeam. The supporting diagonal braces support the bottom of the right crossbeam to improve stability.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: the cardboard is placed on the lifting component and pushed upward. The feeding component pushes the top cardboard to the right and feeds it. The conveying component feeds the cardboard into the printing machine. The positioning component can restrict the two sides of the cardboard, correct the cardboard, and adjust the cardboard to the center position, which is convenient for printing after transportation and improves printing accuracy.
