[0002] An inkjet printer is a product of a large printer series, mainly used for printing large-sized products, and is widely used in the printing operations of advertising curtains and large pictures.

[0003] In the existing patent application with the application number CN201921111276.1 and the name "An Inkjet Printer with Stable Operation", an inkjet printer is disclosed, which includes a frame and a printing platform arranged on the frame. A cross beam is fixedly arranged on the upper side of the printing platform of the frame. A printing carriage is slidably arranged along the length direction of the cross beam. An electromagnet group is fixedly arranged along the length direction of the cross beam. A magnetic attraction member is arranged on one side of the printing carriage close to the electromagnet group. A plurality of magnetic attraction members are arranged in sequence along the length direction of the cross beam on the printing carriage. This inkjet printer completes printing and spraying through the printing carriage moving along the cross beam. However, the spraying carrier used by the inkjet printer has a large volume. The existing inkjet printer requires manual placement and removal of the spraying carrier after spraying, which greatly affects the efficiency of the spraying operation. Therefore, the existing structure of the inkjet printer needs to be further improved. Summary of the Invention

[0004] The purpose of the present invention is to make up for the above deficiencies and disclose to the society a blanking device with a simple and reasonable structure that can achieve automatic blanking.

[0005] The technical solution of the present invention is realized as follows: A blanking device includes a blanking conveyor belt arranged beside the inkjet printer. The blanking conveyor belt is arranged parallel to the feeding direction. Tracks are respectively arranged on both sides of the inkjet printer. A blanking moving frame is arranged across the tracks on both sides. A liftable blanking transfer frame is arranged on the blanking moving frame. A plurality of suction cups are arranged on the blanking transfer frame. The suction cups are connected to a negative pressure device through a conduit; the entire blanking transfer frame is rotatably arranged on the blanking transfer frame.

[0006] Further measures to optimize the technical solution are as follows: As an improvement, the blanking transfer frame is arranged on the blanking lifting frame, and both ends of the blanking lifting frame are in lifting cooperation with the blanking transfer frame.

[0007] As an improvement, guide rails are respectively arranged on both sides of the blanking transfer frame, and both ends of the blanking lifting frame are slidably matched with the corresponding guide rails. The arrangement of the guide rails plays a guiding role and can make the lifting of the lifting frame more stable and smooth.

[0008] As an improvement, a rotating motor is arranged inside the blanking lifting frame. A rotating disc is connected to the rotating motor, and the blanking transfer frame is fixedly connected to the rotating disc. By driving the overall rotation of the blanking transfer frame with the rotating motor, the structure is simple and compact.

[0009] As an improvement, a spring is arranged between the suction cup and the blanking transfer frame. By arranging the spring, when the suction cup presses down, a buffering force can be provided. At the same time, the elastic force of the spring acts on the suction cup to increase the pressure, enabling the suction cup to adsorb the spraying carrier more efficiently.

[0010] As an improvement, a material temporary storage frame is arranged between the spraying machine and the blanking conveyor belt. By arranging the material temporary storage frame, the blanking speed and rhythm can be adjusted.

[0011] As an improvement, a main pushing plate is arranged on the spraying machine, and liftable auxiliary pushing plates are respectively arranged on both sides of the main pushing plate. By adopting a two-stage material pushing structure, long-distance material pushing can be realized and the structure can be made more compact; when the main pushing plate is performing the material pushing operation, the auxiliary pushing plates descend below the platform.

[0012] As an improvement, a cross beam is arranged on the spraying machine, and a print head that can move along the cross beam is arranged on the cross beam.

[0013] The advantages of the present invention compared with the prior art are: A blanking device of the present invention has a simple and reasonable structure. It uses a suction cup on the blanking transfer frame to fix and transfer the spraying carrier by negative pressure adsorption, and through the rotatable setting of the blanking transfer frame, the horizontal and vertical conversion of the spraying carrier is realized, facilitating blanking; as a supporting device of the spraying machine, this blanking device can realize the automatic blanking of the spraying carrier that has completed spraying, and can effectively improve the spraying efficiency.

[0016] The present invention will be further described in detail below with reference to the accompanying drawings: The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations. The basic principles defined in the following description can be used in other implementation schemes, variation schemes, improvement schemes, equivalent schemes, and other technical schemes that do not depart from the spirit and scope of the present invention.

[0017] Those skilled in the art should understand that in the disclosure of the present invention, the terms "longitudinal", "lateral", "upper", "lower", "left", "right", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. indicate the orientation or position based on the orientation or position relationship shown in the accompanying drawings. It is only for the convenience of describing the present invention and is a simplified description, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on the present invention.

[0018] It can be understood that the term "one" should be understood as "at least one" or "one or more". That is, in one embodiment, the number of one component can be one, and in other embodiments, the number of this component can be multiple. The term "one" should not be construed as a limitation on the quantity.

[0019] As Figures 1 to 6 shown, a blanking device includes a blanking conveyor belt 2 arranged beside the inkjet printer 1. The blanking conveyor belt 2 is arranged parallel to the feeding direction. Tracks 3 are respectively arranged on both sides of the inkjet printer 1. A blanking moving frame 4 is arranged across the two tracks 3. A liftable blanking transfer frame 5 is arranged on the blanking moving frame 4. A plurality of suction cups 6 are arranged on the blanking transfer frame 5. The suction cups 6 are connected to a negative pressure device through a conduit; the entire blanking transfer frame 5 is rotatably arranged on the blanking moving frame 4.

[0020] The inkjet carrier can be an inkjet board, a KT board, etc.

[0021] The blanking transfer frame 5 is arranged on a blanking lifting frame 7. Both ends of the blanking lifting frame 7 are in lifting cooperation with the blanking moving frame 4.

[0022] On both sides of the described blanking moving frame 4, guide rails 41 are respectively arranged, and both ends of the blanking lifting frame 7 are slidably matched with the corresponding guide rails 41. The arrangement of the guide rails 41 on both sides can make the movement of the blanking lifting frame 7 more stable and smooth.

[0023] A rotating motor is arranged inside the described blanking lifting frame 7, a rotating disk 71 is connected to the rotating motor, and the blanking transfer frame 5 is fixedly connected to the rotating disk 71.

[0024] The suction cups 6 are evenly arranged on both sides of the blanking transfer frame 5. With such an arrangement, the adsorption force can be evenly distributed, which is beneficial to improving the reliability of adsorption. A spring 61 is arranged between the suction cup 6 and the blanking transfer frame 5. The suction cup 6 is fixed to the bottom of the vertical rod, and the vertical rod can move up and down along the installation position. By setting the spring 61, when the blanking transfer frame 5 moves down to adsorb the painting carrier, a buffer force can be provided. At the same time, the elastic force of the spring 61 gives a downward pressure to the suction cup 6, so that the suction cup 6 can more effectively adsorb the painting carrier.

[0025] A material temporary storage frame 8 is arranged between the described painting machine 1 and the blanking conveyor belt 2. When the painting carriers on the blanking conveyor belt 2 are piled up, the material temporary storage frame 8 can be used to temporarily store the painted carriers, so as to realize the adjustment of the blanking speed and rhythm.

[0026] A main push plate 91 is arranged on the described painting machine 1, and liftable secondary push plates 92 are respectively arranged on both sides of the main push plate 91. The main push plate 91 and the secondary push plates 92 are connected to the corresponding cylinders to realize linear motion.

[0027] In this embodiment, a two-stage pushing structure is adopted. The painting carrier completed by the feeding device is first pushed in the direction of the painting machine 1 under the push of the main push plate 91. At this time, the secondary push plates 92 on both sides sink below the platform under the action of the lifting cylinders to avoid the obstruction of the secondary push plates 92 to the pushing of the painting carrier; when the main push plate 91 is pushed in place, the secondary push plates 92 on both sides rise above the platform under the action of the lifting cylinders, and then are driven by the cylinders for secondary pushing. Thus, long-distance pushing is realized, and the structure is compact and reasonable.

[0028] A cross beam 11 is arranged on the described painting machine 1, and a print head 12 that can move along the cross beam 11 is arranged on the cross beam 11.

[0029] Working principle: After the inkjet printer 1 finishes the inkjet operation on the inkjet carrier (inkjet board, KT board), the inkjet printer 1 moves along the track 3 and leaves the inkjet carrier. The blanking moving frame 4 moves along the track 3 to above the inkjet carrier. The blanking lifting frame 7 drives the blanking transfer frame 5 to descend. After the inkjet carrier is fixed by negative pressure adsorption of the suction cup 6 on the blanking transfer frame 5, the blanking lifting frame 7 rises. The blanking moving frame 4 translates to above the blanking conveyor belt 2. During the blanking translation process, the rotation motor starts and drives the blanking transfer frame 5 together with the inkjet carrier to rotate 90° through the rotating disk 71, so that the inkjet carrier is parallel to the blanking conveyor belt 2 (when the inkjet printer 1 performs inkjet, the inkjet carrier is perpendicular to the blanking conveyor belt 2). The suction cup 6 cuts off the air supply and places the inkjet carrier on the blanking conveyor belt 2, and it is conveyed to the cutting station by the blanking conveyor belt 2, thus completing the blanking.

[0030] When the inkjet carriers on the blanking conveyor belt 2 are stacked, the inkjet carriers on the inkjet platform can be transferred to the material temporary storage box 8 for temporary storage through the blanking transfer frame 5.

[0031] As a supporting device of the inkjet printer, this blanking device can realize the automatic loading of the inkjet carrier and can effectively improve the inkjet efficiency.

[0032] The above are only the preferred embodiments of the present invention, and do not limit the implementation manners and protection scope of the present invention accordingly. For those skilled in the art, it should be realized that all the equivalent replacements and obvious changes made by using the description and illustrations of the present invention should be included in the protection scope of the present invention.
