[0029] like Figures 1 to 6 As shown, a feeding device includes a feeding conveyor belt 2 disposed next to a printer 1. The feeding conveyor belt 2 is arranged parallel to the feeding direction. Tracks 3 are respectively disposed on both sides of the printer 1. A feeding moving frame 4 is disposed across the tracks 3 on both sides. A lifting feeding transfer frame 5 is disposed on the feeding moving frame 4. A plurality of suction cups 6 are disposed on the feeding transfer frame 5. The suction cups 6 are connected to a negative pressure device through conduits. The feeding transfer frame 5 is rotatably disposed on the feeding moving frame 4.
[0030] The printing medium can be a printing plate, KT board, etc.
[0031] The unloading transfer frame 5 is mounted on the unloading lifting frame 7, and the two ends of the unloading lifting frame 7 are in lifting cooperation with the unloading moving frame 4.
[0032] The unloading moving frame 4 is provided with guide rails 41 on both sides, and the two ends of the unloading lifting frame 7 are slidably engaged with the corresponding guide rails 41. The provision of guide rails 41 on both sides enables the unloading lifting frame 7 to move more smoothly and steadily.
[0033] The unloading lifting frame 7 is equipped with a rotating motor, and a rotating disk 71 is connected to the rotating motor. The unloading transfer frame 5 is connected and fixed to the rotating disk 71.
[0034] The suction cups 6 are evenly distributed on both sides of the unloading transfer frame 5. This arrangement ensures a uniform distribution of adsorption force, which improves the reliability of adsorption. A spring 61 is installed between the suction cups 6 and the unloading transfer frame 5. The suction cups 6 are fixed to the bottom of the vertical rod, which can move up and down along the installation position. The spring 61 provides a buffering force when the unloading transfer frame 5 moves down to adsorb the inkjet carrier. At the same time, the elastic force of the spring 61 applies downward pressure to the suction cups 6, allowing the suction cups 6 to more effectively adsorb the inkjet carrier.
[0035] A material storage frame 8 is provided between the inkjet printer 1 and the feeding conveyor belt 2. When inkjet carriers accumulate on the feeding conveyor belt 2, the material storage frame 8 can be used to temporarily store the inkjet carriers that have been printed, thereby adjusting the feeding speed and pace.
[0036] The inkjet printer 1 is equipped with a main push plate 91, and two adjustable auxiliary push plates 92 are respectively provided on both sides of the main push plate 91. The main push plate 91 and the auxiliary push plates 92 are connected to corresponding cylinders to achieve linear motion.
[0037] In this embodiment, a two-stage pushing structure is adopted. The inkjet printing carrier, after being loaded by the feeding device, first moves towards the inkjet printer 1 under the push of the main push plate 91. At this time, the auxiliary push plates 92 on both sides are lowered below the platform under the action of the lifting cylinder to avoid obstructing the pushing of the inkjet printing carrier. After the main push plate 91 pushes the carrier into place, the auxiliary push plates 92 on both sides rise above the platform under the action of the lifting cylinder, and are then driven by the cylinder for a second push. This achieves long-distance pushing with a compact and reasonable structure.
[0038] The inkjet printer 1 is provided with a crossbeam 11, and a print head 12 that can move along the crossbeam 11 is provided on the crossbeam 11.
[0039] Working principle:
[0040] After the inkjet printer 1 completes the inkjet printing operation on the inkjet printing carrier (inkjet board, KT board), the inkjet printer 1 moves along the track 3 and leaves the inkjet printing carrier. The unloading moving frame 4 moves along the track 3 to above the inkjet printing carrier. The unloading lifting frame 7 drives the unloading transfer frame 5 to descend. After the inkjet printing carrier is fixed by the negative pressure adsorption of the suction cup 6 on the unloading transfer frame 5, the unloading lifting frame 7 rises. The unloading moving frame 4 moves horizontally to above the unloading conveyor belt 2. During the unloading horizontal movement, the rotating motor starts and drives the unloading transfer frame 5 and the inkjet printing carrier to rotate 90° through the rotating disk 71, so that the inkjet printing carrier is parallel to the unloading conveyor belt 2 (when the inkjet printer 1 is printing, the inkjet printing carrier is perpendicular to the unloading conveyor belt 2). The suction cup 6 cuts off the air and places the inkjet printing carrier on the unloading conveyor belt 2, which is then transported to the cutting station by the unloading conveyor belt 2, thus completing the unloading.
[0041] When inkjet printing media accumulate on the unloading conveyor belt 2, the inkjet printing media on the inkjet printing platform can be transferred to the material storage box 8 for temporary storage via the unloading transfer frame 5.
[0042] This feeding device, as an accessory to the inkjet printer, can automatically feed the inkjet printing media, effectively improving printing efficiency.
[0043] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
