Description

Technical Field

[0001] The present invention relates to the technical field of packaging and printing, and in particular to a packaging and printing device dedicated to visual communication design. Background Art

[0002] With the continuous development of social economy and the diversification of consumer markets, packaging design plays an increasingly important role in commodity marketing. Packaging is not only a tool to protect commodities, but also an important carrier of brand image, which can attract consumers' attention and convey the value and cultural connotation of products. Therefore, it is necessary to use packaging printing devices to efficiently and accurately realize the visual communication design concept. The existing packaging printing devices still have some shortcomings.

[0003] The invention patent with the publication number CN114347672B discloses a printing process for the cover pattern for wine packaging, which is mainly composed of a servo main drive mechanism, an integrated controller, a top screw servo system, a top print head, a side screw servo system, a side print head, a servo shaft, etc. The present invention controls the top screw servo system to drive the top print head through the integrated controller to print the top pattern of the cover; controls the side screw servo system to drive the side print head and controls the servo shaft to print the side pattern of the cover. The computer is directly used to design the pattern for printing, and plate making is not required, and the pattern change is convenient; the printed pattern is colorful and three-dimensional, the pattern has strong gradient, and the visual effect is good, which greatly increases the aesthetics of the cover; the ink uses green and environmentally friendly UV ink, and is only printed in the required pattern area, which saves the ink cost and achieves environmental protection and energy saving effects; the equipment occupies a small space, and the land cost is greatly reduced.

[0044] It should be noted that the present invention is a packaging printing device dedicated to visual communication design. First, Figure 1 and Figure 5As shown, when the device is in use, the second connecting tube 601 on the supporting component 6 can be fixed on the top of the wall. The device can adapt to packaging materials of different heights and different lengths for printing. First, the first motor 401 on the first adjusting component 4 drives the screw 402 to rotate, thereby driving the slider 403 to move up and down in the supporting tube 1. During the movement of the slider 403, the first connecting block 501 on the second adjusting component 5 can be driven to move up and down. The steering component 7 above will move up and down straightly through the pipe sleeve 606 and the second connecting rod 605, thereby pressing the packaging from top to bottom, so as to adapt to packaging materials of different heights for subsequent printing. When the first electric push rod 502 is extended or shortened, it will drive the second slide bar 504 to slide outside the first guide rod 503, so as to adjust the device's support and downward pressure position on the packaging. When the second slide bar 504 slides, it will drive the first connecting rod 604, the second connecting rod 605 and the sleeve 606 to move, and the third slide bar 602 will slide in the second connecting tube 601. The connecting rod 603 will drive the first slide bar 3 to slide, so as to subsequently adjust the positions of the first slide bar 3, the sleeve 606 and the two sets of steering components 7 synchronously, so as to adapt to the support and printing of packaging materials of different heights and lengths. Figure 5 and Figure 7 As shown, the second conveyor belt 31 conveys the articles to the appropriate positions on the upper and lower steering assemblies 7, and the first gear 703 is driven to rotate by the second motor 702 in the housing 701, and the first gear 703 drives the gear ring 704 to rotate. When the gear rings 704 on the steering assemblies 7 on the upper and lower sides of the device rotate in different directions, the damping blocks 706 in the grooves 705 support the packaged objects, and the damping blocks 706 on the upper and lower steering assemblies 7 rotate the packaged objects in the same direction for subsequent flipping and printing.

[0045] like Figure 1-Figure 6 and Figure 8As shown, the packaging bag needs to be tightened before printing, and the range of flattening is adjusted according to the height of the packaging bag. The docking rod 23 is installed in the first rotating drum 2105 and the second rotating drum 2108, so that the first synchronous belt 2106 on the device can cooperate with the second synchronous belt 25 to extend upward, and the third motor 2101 on the supporting plate 20 is used to drive the second gear 2102 to rotate, and the second gear 2102 will also drive the third gear 2103 to rotate in the opposite direction, so that the two sets of third connecting shafts 2104 on the device rotate in the opposite direction, and the first rotating drum 2105 and the second rotating drum 2108 keep rotating in the opposite direction. When the first rotating drum 2105 and the second rotating drum 2108 rotate in the opposite direction, the two first synchronous belts 2106 will rotate in the opposite direction, so as to subsequently flatten the printing position of the packaging material. When the first rotating drum 2105 and the second rotating drum 2108 rotate, the third rotating drum 22 and the fourth rotating drum 24 will be driven to rotate, so that the two second synchronous belts 25 above the device rotate in the opposite direction, so that the device can perform smoothing and printing work on packaging bags with higher heights. The first magnetic block 28 and the second magnetic block 30 can be adsorbed at appropriate positions on the first sliding rod 3 according to the required smoothing position, thereby changing the position of the support rod 27 and the angle of the first synchronous belt 2106. The third elastic belt 29 can change the stretching length of the first synchronous belt 2106 and the second synchronous belt 25. The first elastic belt 2107 and the second elastic belt 26 can adapt to the first synchronous belt 2106 and the second synchronous belt 25 under different stretching degrees, so as to accurately adjust the smoothing position later.

[0046] During printing, the second electric push rod 607 between the first connecting rod 604 and the connecting frame 8 is extended, and the second electric push rod 607 pushes the connecting frame 8 to move toward the side close to the packaging object, and the second printing plate 16 on the connecting frame 8 prints on the abutting packaging material. The second printing plate 16 is pressed after abutting the surface of the packaging material, and the first guide block 9 on the second connecting block 11 stretches the first spring 10, so that the first printing plate 15 contacts the second printing plate 16 for inking. The device can ink the first printing plate 15 through the traction assembly 17, such as Figure 2-Figure 4As shown, when the connecting frame 8 moves, the second connecting cylinder 601 remains stationary, so the position of the connecting frame 8 can be adjusted by shortening the second electric push rod 607 or extending the first electric push rod 502, so that the traction steel rope 1705 pulls the second guide rod 1701 to slide in the fixing ring 1702, driving the bottom plate 1703 and the connecting shell 13 to move upward, and the sealing gasket 1704 keeps the connecting shell 13 and the bracket of the connecting frame 8 sealed. The ink in the connecting shell 13 will automatically ink the first printing plate 15 through the through hole 14. The fixing frame 1801 is used to support the connecting ring 1802, and the second spring 1803 on the connecting ring 1802 can tighten the pressure rod 1804 and the pressure plate 1805, so that the connecting shell 13 on the device remains in a compressed state. The mutually abutting pressure plate 1805 and the first conveyor belt 1806 enable the first conveyor belt 1806 to move when the connecting shell 13 moves up and down, thereby preventing the pressure plate 1805 from sliding directly on the connecting shell 13 and causing wear, thereby ensuring the sealing effect of the connecting shell 13 and extending the service life of the device.
