Description

Technical Field

[0001] The utility model belongs to the technical field of digital printing, in particular to a flash-jet ink-connecting and flipping mechanism. Background Art

[0002] With the development of printing technology, digital printing has become widely adopted. This new printing method uses electronic text as a carrier, transmitted via the network to digital printing equipment, achieving direct printing. In sheet-fed printing devices, the platform absorbs the paper and runs it to the bottom of the printhead on the base plate for printing. When the printhead needs maintenance, the machine must be stopped, the printhead on the printing base plate flashes, and then the machine is restarted to continue printing. This maintenance method is inefficient, requires manual intervention, and lacks intelligence, so a new device needs to be designed. Utility Model Content

[0003] The purpose of the utility model is to provide a flash inkjet ink-connecting flipping mechanism to solve the problems raised in the above background technology.

[0004] To achieve the above objectives, the present invention provides the following technical solutions:

[0005] A flash inkjet ink receiving and flipping mechanism includes a suction platform, a bottom plate nozzle is arranged above the suction platform, transmission rollers are symmetrically arranged on both sides of the suction platform, and also includes a rotating drum arranged in the middle of the suction platform, a transmission shaft is installed in the middle of the rotating drum, a servo motor is provided at one end of the transmission shaft, an ink receiving disk is rotatably installed in the middle of the transmission shaft, and a number of avoidance openings are evenly distributed on the circumference of the rotating drum.

[0006] Furthermore: three avoidance openings are provided to facilitate quick switching.

[0007] Furthermore, the rotating drum and the transmission shaft are riveted together, ensuring that the transmission shaft drives the rotating drum to rotate.

[0008] Furthermore, the ink receiving tray is bucket-shaped, and its length is greater than that of the avoidance opening, thereby ensuring comprehensive ink collection.

[0009] Compared with the prior art, the beneficial effects are:

[0010] 1. By rotating the roller to switch the working state, the printing operation can be flashed and maintained at the same time, shortening the printing time and improving efficiency;

[0011] 2. Simple structure and easy function increase the smoothness of operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 This is a structural diagram of a flash inkjet ink-connecting and flipping mechanism of the present invention;

[0013] Figure 2 This is an appearance diagram of a flash inkjet ink-connecting and flipping mechanism described in the present invention.

[0014] In the accompanying drawings: 1. transmission roller; 2. ink receiving tray; 3. bottom plate nozzle; 4. rotating roller; 5. servo motor; 6. avoidance port; 7. suction platform; 8. paper; 9. transmission shaft. DETAILED DESCRIPTION

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0016] See also Figure 1-Figure 2 A flash inkjet ink receiving and flipping mechanism includes a suction platform 7, a bottom plate nozzle 3 is arranged above the suction platform 7, transmission rollers 1 are symmetrically arranged on both sides of the suction platform 7, and a rotating drum 4 is arranged in the middle of the suction platform 7. A transmission shaft 9 is installed in the middle of the rotating drum 4, and a servo motor 5 is provided at one end of the transmission shaft 9. An ink receiving disk 2 is rotatably installed in the middle of the transmission shaft 9, and a number of avoidance openings 6 are evenly distributed on the circumference of the rotating drum 4.

[0017] Furthermore: three avoidance ports 6 are provided for quick switching; the rotating drum 4 and the transmission shaft 9 are riveted together to ensure that the transmission shaft 9 drives the rotating drum 4 to rotate; the ink receiving tray 2 is bucket-shaped, and its length is greater than the length of the avoidance port 6, ensuring comprehensive ink collection.

[0018] Working principle: the transmission roller 1 pushes the paper 8 to move along the suction platform 7. When the leading edge of the paper 8 is about to leave the suction platform 7 (if the bottom plate nozzle 3 needs to flash spray), the servo motor 5 drives the transmission shaft 9 to drive the rotating drum 4 to rotate, so that the avoidance port 6 on the rotating drum 4 rotates to the bottom of the bottom plate nozzle 3, and the bottom plate nozzle 3 flashes and sprays, and the waste ink passes through the avoidance port 6 and falls into the ink receiving tray 2 below; after the flash spraying is completed, the servo motor 5 drives the transmission shaft 9 to drive the rotating drum 4 to rotate, and the avoidance port 6 on the rotating drum 4 rotates to the side, and the rotating drum 4 blocks the ink receiving tray 2. The paper 8 continues to move in the direction of transmission of the suction platform 7, and moves to the bottom of the bottom plate nozzle 3 for printing. When flash spraying maintenance is needed again, the above process can be repeated.

[0019] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
