Description

Technical Field

[0001] The invention relates to the technical field of industrial UV printers, in particular to an ultra-large format industrial UV flatbed printer. Background Art

[0002] UV printers are also called universal flatbed printers or flatbed printers. This type of printer has the advantages of printing from one sheet, no need for plate making, and full-color images completed at one time, and is widely used. The difference between it and traditional inkjet printing is that the equipment has UV ink and UV lamp. It uses the components in UV ink to undergo cross-linking polymerization under the specific wavelength of ultraviolet light to accelerate the film formation of ink, so that it can be printed and dried immediately and sampled immediately. It also solves the problem that white ink cannot be used together with color ink, forming a unique artistic style.

[0003] The UV printer in the prior art can print different patterns on the plates during use, but the UV printer is exposed indoors. When people pass by or the equipment moves, dust will be raised. When the dust and the printed pattern are mixed, it will affect the appearance of the finished product, thus causing the product to be scrapped. At the same time, the printing of industrial plates needs to maintain a high degree of accuracy. The traditional method is not convenient for fixing it to the plate, and any position deviation will affect the printing effect.

[0004] When applying for the present invention, the applicant found through search that a Chinese patent disclosed an "ultra-large format industrial UV flatbed printer" with the application number "202221425062.3". The patent is mainly limited by the printing format composed of an integral steel frame base and a printing platform, which has a high degree of integration and reduces the on-site debugging and installation links. It cooperates with two horizontal and vertical tracks and the corresponding mobile trolley and printing trolley to realize large-format flat printing. On this basis, by installing a pair of negative pressure cleaning boxes on the printing trolley, using the negative pressure generating device inside the printing trolley, and then cooperating with the cleaning head extending to the unprinted part on the printing platform, as the printing trolley moves, the part to be printed can be pre-negatively cleaned with negative pressure. However, position offset during the placement of the plate will also affect the printing effect. Therefore, according to the applicant's invention, an ultra-large format industrial UV flatbed printer was invented, which solves the problem that the traditional method is not convenient for fixing it to the plate, and the printing effect will be affected when the position is offset. Summary of the invention

The front side of the printer body 7 is fixedly connected to a second fixed plate 17, and the middle part of the second fixed plate 17 is fixedly connected to a driving motor 6. During the printing process, the driving motor 6 is arranged at the front side of the printer body 7, and the plate can be brushed by a brush 16 structure to clean the attached dust. The driving end of the driving motor 6 is fixedly connected to a brush 16, and the impurities and dust can be brushed and lifted up by the brush 16 structure, and the suction cup 15 structure can be used to suck up the impurities and dust. Dust and impurities are absorbed and enter, and cleaning work can be done before printing to provide a clean and pure printing environment. Suction cups 15 are fixedly connected to both sides of the middle of the second fixed plate 17. After cleaning, the floating dust will be absorbed into the connecting pipe 18 through the suction cup 15, and flow into the interior of the vacuum box 2 through the hose 9. One end of the suction cup 15 is fixedly connected to the connecting pipe 18, and one end of the connecting pipe 18 is fixedly connected to the hose 9. The setting of the hose 9 can prevent pulling during the position movement process. The end of the hose 9 away from the printer body 7 is fixedly connected to the vacuum box 2, and the middle of the vacuum box 2 is fixedly connected to a fixed filter 30. The fixed filter 30 can block and filter the floating dust inside the vacuum box 2. To prevent dust from entering the interior of the vacuum pump 29 and causing damage to the vacuum pump 2, a vacuum pump 29 is provided on one side of the interior of the vacuum box 2, and a collection frame 28 is provided at the bottom of the other side of the interior of the vacuum box 2. The dust falls into the interior of the collection frame 28 by gravity for unified treatment.

A bellows 11 is fixedly connected to the middle of the hose 9, and the distance stretching effect is achieved through the bellows 11.

[0032] A toothed disc 23 is rotatably connected at the middle of the upper part of the main body 1 of the printing device. The toothed disc 23 is driven to rotate by a servo motor. After rotation, it meshes with the bevel gear 22 to complete the rotation of the screw rod 24. After rotation, it is threadedly matched with the threaded block 25 to realize threaded movement.

Then the gas can only enter through the suction cup 15 and the vacuum air hole 5 to absorb the gas. The vacuum tube 19 and the vacuum box 2 are fixedly connected.

[0033] Working principle: When in use, first place the industrial plate to be printed on the top of the printing platform 4, and then adjust the plastic film 14 according to the position of the industrial plate. The vacuum air holes 5 can be blocked through the structure of the plastic film 14, which is convenient for vacuum adsorption of the vacuum air holes 5 in the middle structure and fixation of the plate. During operation, the toothed disc 23 can be driven by a servo motor to rotate, and after rotation, it meshes with the bevel gear 22 to complete the rotation of the screw rod 24. After rotation, it is threadedly matched with the threaded block 25 to achieve thread movement. When the threaded block 25 moves, the plastic film 14 will be moved through the connecting frame 26 to control the telescopic distance at both ends to complete the blocking of the vacuum air holes 5. Then, the internal gas of the vacuum box 2 is discharged through the vacuum pump 19, which is in a negative pressure state. Then the gas can only be sucked out through the suction The disc 15 enters and the vacuum air hole 5 absorbs the gas. When the vacuum air hole 5 enters the gas, it can absorb and fix the industrial plate to achieve the position fixing effect; when the printer body 7 is working, the guide rail 12 cooperates to realize the lateral position movement, and the rotation of the threaded rod 10 can cause the threaded movement of the moving platform 13, and the longitudinal position movement of the printer body 7 can be realized, and the lateral and longitudinal movement printing operations of the printer body 7 can be completed. During the printing process, the driving motor 6 is arranged on the front side of the printer body 7, and the plate can be brushed by the brush 16 structure to clean the attached dust. After cleaning, the floating dust will be absorbed by the suction cup 15 into the connecting pipe 18, and flow into the interior of the vacuum box 2 through the hose 9, and fall into the collection frame 28 for unified treatment due to the gravity of the dust.
