This inkjet printer completes printing and inkjet printing through the printing carriage moving along the crossbeam. However, the inkjet printing media used by this printer is very large, and existing inkjet printers require manual placement and removal of the media after printing, significantly affecting the efficiency of the printing operation. Therefore, the existing inkjet printer structure needs further improvement. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned deficiencies and to disclose to the public a simple and reasonable inkjet printing device that can automatically load and unload materials and effectively improve the efficiency of inkjet printing operations.

[0005] The technical solution of this utility model is implemented as follows:

[0006] A printing device includes a printer, a material storage frame, and a feeding conveyor belt. A printing platform is located below the printer. The material storage frame is positioned at the front of the printer. Feeding rails are located on both sides between the printer and the material storage frame. A feeding moving frame is mounted across the feeding rails, and a liftable feeding transfer frame is mounted on the feeding moving frame. The feeding conveyor belt is located at the rear of the printer. Feeding rails are located on both sides between the printer and the feeding conveyor belt. A feeding moving frame is mounted across the feeding rails, and a liftable feeding transfer frame is mounted on the feeding moving frame. Both the feeding and feeding transfer frames are equipped with several suction cups, which are connected to a negative pressure device via conduits. A main push plate is located on the printing platform, and liftable auxiliary push plates are located on both sides of the main push plate.

[0007] Further optimization measures for this technical solution are as follows:

[0008] As an improvement, the printing platform extends towards the material storage frame to form a pre-processing platform. A fixed baffle is provided on one side of the pre-processing platform, and a movable pusher driven by a drive device is provided on the other side. Through the cooperation of the fixed baffle and the movable pusher, the printing medium is positioned in a set location to ensure the accuracy of subsequent printing medium delivery and guarantee printing quality.

[0009] As an improvement, the feeding moving frame is provided with feeding guide rails on both sides, and a feeding lifting frame is slidably arranged on the feeding guide rails. The feeding transfer frame is fixed on the feeding lifting frame.

[0030] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious modifications will be apparent to those skilled in the art. The basic principles of the present invention defined in the following description can be used in other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0031] Those skilled in the art should understand that in the disclosure of this utility model, the terms "longitudinal", "lateral", "up", "down", "left", "right", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or position based on the orientation or positional relationship shown in the accompanying drawings. They are only for the purpose of simplifying the description of this utility model and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this utility model.

[0032] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0033] like Figures 1 to 9 As shown, a printing device includes a printer 1, a material storage frame 2, and a feeding conveyor belt 3. A printing platform 11 is located below the printer 1. The material storage frame 2 is positioned in front of the printer 1. Feeding rails 4 are located on both sides between the printer 1 and the material storage frame 2. A feeding moving frame 41 is mounted on the feeding rails 4 spanning both sides, and a liftable feeding transfer frame 42 is mounted on the feeding moving frame 41. The feeding conveyor belt 3 is located behind the printer 1. Material feeding tracks 5 are provided on both sides between the printing machine 1 and the material feeding conveyor belt 3. Material feeding moving frames 51 are provided on the material feeding tracks 5 spanning both sides. Material feeding moving frames 51 are provided with lifting material transfer frames 52. Material feeding transfer frames 42 and material feeding transfer frames 52 are provided with several suction cups 6. The suction cups 6 are connected to a negative pressure device through conduits. The inkjet printing platform 11 is provided with a main push plate 71. Liftable auxiliary push plates 72 are provided on both sides of the main push plate 71.

[0034] The printing medium can be a printing plate, KT board, etc.

[0035] Due to the large volume of the inkjet printing media and the long axial length of the inkjet printing equipment, a two-stage pushing structure is adopted. The main push plate 71 and the auxiliary push plate 72 are connected to corresponding cylinders to achieve linear movement. After the inkjet printing media is loaded, it first moves towards the inkjet printer 1 under the push of the main push plate 71. At this time, the auxiliary push plates 72 on both sides are lowered below the inkjet printing platform 11 by the lifting cylinders to avoid obstructing the pushing of the inkjet printing media. After the main push plate 71 pushes it into place, the auxiliary push plates 72 on both sides rise above the inkjet printing platform 11 by the lifting cylinders, and are then pushed a second time by the cylinders. This achieves long-distance pushing with a compact and reasonable structure.

[0036] The inkjet printing platform 11 extends towards the material storage frame 2 to form a pre-conditioning platform 12. A fixed baffle 81 is provided on one side of the pre-conditioning platform 11, and a movable push plate 82 driven by a drive device is provided on the other side. In this embodiment, the movable push plate 82 is driven by a cylinder located below the pre-conditioning platform 12.

[0037] During the loading and unloading process of the inkjet printing carrier, slight displacement may occur. The pre-adjustment platform 12 can adjust the inkjet printing carrier to the set position. Specifically, the cylinder drives the moving push plate 82 to move towards the fixed baffle 81 (since the inkjet printing carrier is displaced due to its descent, the displacement is very small, and the moving push plate 82 only needs to move a short distance) until the inkjet printing carrier abuts against the fixed baffle 81, ensuring that the inkjet printing carrier is in the set position, thereby ensuring the accuracy of subsequent inkjet printing carrier delivery and ensuring the consistency of printing on each inkjet printing carrier.

[0038] The loading moving frame 41 is provided with loading guide rails 43 on both sides, and a loading lifting frame 44 is slidably mounted on the loading guide rails 43. The loading transfer frame 42 is fixed on the loading lifting frame 44. The loading guide rails 43 serve as guides, making the lifting of the loading lifting frame 44 more stable and smooth.

[0039] The unloading moving frame 51 is provided with unloading guide rails 53 on both sides, and an unloading lifting frame 54 is slidably mounted on the unloading guide rails 53. The unloading transfer frame 52 is mounted on the unloading lifting frame 54. Similarly, the unloading guide rails 53 also serve as guides, making the lifting of the unloading lifting frame 54 more stable and smooth.

[0040] The feeding conveyor belt 3 is arranged parallel to the feeding direction. The feeding lifting frame 54 is equipped with a rotating motor. The rotating motor is connected to a rotating disk 55. The feeding lifting frame 54 is connected and fixed to the rotating disk 55.

[0041] A spring 61 is provided between the suction cup 6 and the loading transfer frame 42 and the unloading transfer frame 52. The suction cup 6 is 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 pick up the inkjet carrier. At the same time, the elastic force of the spring 61 gives the suction cup 6 downward pressure, so that the suction cup 6 can pick up the inkjet carrier more effectively.

[0042] A material storage frame 9 is provided between the inkjet printer 1 and the feeding conveyor belt 3. When inkjet carriers accumulate on the feeding conveyor belt 3, the material storage frame 9 can be used to temporarily store the inkjet carriers that have been printed, thereby adjusting the feeding speed and pace.

[0043] The storage frame 2 includes a base frame 21. Limiting posts 22 are provided at the four corners of the base frame 21. Limiting grooves 22a are provided on the inner side of each limiting post 22. Outwardly extending guide portions 22b are provided at the upper ends of each limiting post 22. The limiting posts 22 at the four corners define the placement area of ​​the inkjet printing carrier. The limiting posts 22 with limiting grooves 22a are used to limit the placement of the inkjet printing carrier in the designated position, preparing it for subsequent loading.

[0044] The structure of the material temporary storage frame 9 is the same as that of the storage frame 2, and the material is stored by limiting the position of the four corner posts 22.

[0045] The inkjet printer 1 is provided with a crossbeam 13, and a print head 14 that can move along the crossbeam 13 is provided on the crossbeam 13.

[0046] Working principle:

[0047] First, stack the printing media (printing board, KT board, etc.) to be printed in the storage frame 2. Start the equipment, and the loading transfer frame 42 moves along the loading track 4 to above the storage frame 2. The loading lifting frame 44 drives the loading transfer frame 42 to descend. After the printing media is fixed by the negative pressure adsorption of the suction cup 6 on the loading transfer frame 42, the loading lifting frame 44 rises. After the loading lifting frame 44 moves horizontally to above the pre-sorting platform 12, the loading lifting frame 44 descends, and the suction cup 6 cuts off the air supply and lowers the printing media.

[0048] On the pre-conditioning platform 12, the cylinder drives the movable push plate 82 to move towards the fixed baffle 81 until the inkjet carrier abuts against the fixed baffle 81, so that the inkjet carrier is in the set position.

[0049] The lifting cylinder drives the auxiliary push plate 72 to descend below the inkjet printing platform 11. After the cylinder drives the main push plate 71 to push the inkjet carrier to the set position, the lifting cylinder drives the auxiliary push plate 72 to rise above the inkjet printing platform 11. Then, the cylinder drives the auxiliary push plate 72 to push it a second time, moving the inkjet carrier below the inkjet printer 1, whereby the inkjet printer 1 completes the inkjet printing process.

[0050] 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 unloading track 5 and leaves the inkjet printing carrier. The unloading moving frame 51 moves along the unloading track 5 to above the inkjet printing carrier. The unloading lifting frame 54 drives the unloading transfer frame 52 to descend. After the inkjet printing carrier is fixed by the negative pressure adsorption of the suction cup 6 on the unloading transfer frame 52, the unloading lifting frame 54 rises. The unloading moving frame 51 moves horizontally to above the unloading conveyor belt 3. During the unloading horizontal movement, the rotating motor starts and drives the unloading transfer frame 52 and the inkjet printing carrier to rotate 90° through the rotating disk 55, so that the inkjet printing carrier is parallel to the unloading conveyor belt 3 (when the inkjet printer 1 is printing, the inkjet printing carrier is perpendicular to the unloading conveyor belt 3). In this way, the unloading is completed.

[0051] When inkjet printing media accumulate on the unloading conveyor belt 3, the inkjet printing media on the inkjet printing platform can be transferred to the material storage box 9 for temporary storage via the unloading transfer frame 52.

[0052] This inkjet printing equipment can automatically load and unload printing media and transfer them on the equipment, which can effectively improve printing efficiency and reduce the labor intensity of operators.

[0053] 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.
