Detailed implementation
[0019] The present utility model will be further described in detail below in conjunction with the accompanying drawings and through embodiments. The following embodiments are explanations of the present utility model, and the present utility model is not limited to the following embodiments.
[0020] See Figures 1-5 , a double-sided synchronous high-efficiency printing device in this embodiment includes a number of printing units 1 arranged in a straight line and side by side. The number of printing units 1 is divided into an upper printing unit 11 and a lower printing unit 12. The upper printing unit 11 and the lower printing unit 12 are alternately connected left and right in sequence. The upper printing unit 11 is used for printing the upper side of the paper, and the lower printing unit 12 is used for printing the lower side of the paper.
[0021] The present utility model passes the paper to be printed through multiple upper printing units 11 and lower printing units 12 in sequence, and the upper printing unit 11 and the lower printing unit 12 respectively print the upper and lower sides of the paper, so that the paper does not need to be flipped, reducing the complexity of the operation process and improving the printing efficiency. It can also reduce the probability of paper deformation. At the same time, multiple upper printing units 11 and multiple lower printing units 12 can achieve multi-color group color printing on the upper and lower sides of the paper. The number of upper printing units 11 and lower printing units 12 can be adjusted according to actual printing needs to meet different printing requirements.
[0022] The upper printing unit 11 and the lower printing unit 12 are arranged alternately, so that after printing is completed on one side of the paper, the ink on this side can have a certain time to dry and set, reducing the occurrence of blurred handwriting and patterns caused by continuous printing and improving the printing quality.
[0023] See Figures 1-3 , the printing unit 1 includes a printing mechanism 13 and two support plates 14. The two support plates 14 are arranged in parallel on the front and rear sides of the printing mechanism 13. Turntables 15 are fixed on the front and rear sides of the printing mechanism 13. The turntables 15 are respectively rotatably arranged on the two support plates 14. The upper printing unit 11 and the lower printing unit 12 adopt the same printing mechanism 13. Paper can be input from both the left and right sides of the printing mechanism 13 for printing and output from the other side.
[0024] By rotating the turntable 15, the printing mechanism 13 is flipped so that the printing unit 1 can be switched between the upper printing unit 11 and the lower printing unit 12. Since the paper can be input for printing on both the left and right sides of the printing mechanism 13, the flipped printing mechanism 13 can cooperate with the unflipped printing mechanism 13 to achieve one-way conveying of the paper and print on both the upper and lower sides of the paper. At the same time, when manufacturing the present utility model, only the same printing unit 1 needs to be manufactured. During use, the printing unit 1 is switched into the upper printing unit 11 and the lower printing unit 12 by flipping the printing mechanism 13 according to the usage requirements, which can reduce the manufacturing difficulty of the present utility model, reduce the manufacturing cost of the present utility model, and also facilitate the use with different numbers of upper printing units 11 and lower printing units 12 during use.
[0025] See Figure 2 , the printing mechanism 13 includes an ink roller 16, a printing roller 17, and a squeezing roller 18 arranged in parallel. The ink roller 16, the printing roller 17, and the squeezing roller 18 are all rotatably arranged on the turntable 15. Ink troughs 19 are arranged on both the upper and lower sides of the ink roller 16, and the upper and lower sides of the ink roller 16 are respectively located in two ink troughs 19. The printing roller 17 is in contact with the ink roller 16. A gap for the paper to pass through is provided between the squeezing roller 18 and the printing roller 17. The printing roller 17 is driven to rotate by a driving motor 20.
[0026] During use, the paper is inserted and clamped between the printing roller 17 and the squeezing roller 18 from one side of the printing mechanism 13. The driving motor 20 drives the printing roller 17 to rotate and cooperate with the squeezing roller 18 to drive the paper to move to the other side of the printing mechanism 13. The printing roller 17 is pre-engraved with inwardly recessed text and pattern indentations. The ink roller 16 in contact with the printing roller 17 is driven to rotate by the printing roller 17, and the ink in the ink trough 19 is adhered and transferred into the indentations on the printing roller 17. Thus, when the printing roller 17 is in contact with the paper, the ink in the indentations can adhere to the paper to achieve printing. This printing mechanism 13 has a simple structure and is convenient for operation and maintenance.
[0027] In this embodiment, ink troughs 19 are arranged on both the upper and lower sides of the ink roller 16. Therefore, when the printing mechanism 13 is flipped to form the upper printing unit 11 and the lower printing unit 12, the ink troughs 19 located on the lower side of the ink roller 16 can be respectively used for ink supply.
[0028] See Figure 2 , a plurality of scraping blades 21 are arranged in contact on both the ink roller 16 and the printing roller 17. The contact position of the scraping blade 21 on the ink roller 16 with the ink roller 16 is in the vertical direction of the ink trough 19.
[0029] The scraper 21 can scrape off the excessive ink on the ink roller 16, avoiding the ink roller 16 from transferring excessive ink to the printing roller 17. Since the amount of ink on the ink roller 16 is large, the scraped-off ink can accumulate and then fall back into the ink fountain 19 below for reuse. At the same time, the scraper 21 scrapes off the excess ink on the printing roller 17, reducing the probability that the excess ink adheres to the paper and causes a reduction in printing quality.
[0030] See Figure 3 、 Figure 4 As shown in, two racks 22 are provided at the bottom end of the ink fountain 19. Slide seats 23 are provided on the turntables 15 of the two support plates 14. A gear 24 is provided in the slide seat 23. The two racks 22 are respectively arranged to slide up and down in the two slide seats 23 and the rack 22 meshes with the gear 24. The gear 24 rotates and can be fixedly arranged in the slide seat 23.
[0031] By rotating the gear 24 to drive the rack 22 to move up and down, the height of the ink fountain 19 is adjusted, so that the ink roller 16 can contact the ink in the ink fountain 19. When the amount of ink in the ink fountain 19 decreases and this printing job is about to end, the ink fountain 19 can be moved upward so that the ink roller 16 can contact the ink at the bottom of the ink fountain 19, reducing the remaining amount of ink in the ink fountain 19 and improving the utilization rate of the ink. After the ink fountain 19 is used for a period of time or when other colors of ink need to be replaced, the ink fountain 19 can be driven to move downward by rotating the gear 24, which is convenient for cleaning the ink fountain 19 and improving the convenience of using the present utility model.
[0032] See Figure 3 、 Figure 5 As shown in, the gears 24 in the two slide seats 23 are coaxially fixed by a connecting rod 25. A rotating rod 26 is provided in any one of the slide seats 23. The rotating rod 26 is coaxially slidably connected to the gear 24 in the slide seat 23 through a first spline 27. The rotating rod 26 passes through and is slidably arranged on the turntable 15. The rotating rod 26 is slidably connected to the turntable 15 through a second spline 28. A handle 29 is provided at the outer end of the rotating rod 26.
[0033] By pulling out the rotating rod 26 outward through the handle 29, the internal and external splines of the second spline 28 between the rotating rod 26 and the turntable 15 are separated. However, the length of the external spline of the first spline 27 between the rotating rod 26 and the gear 24 is greater than that of the internal spline. When the rotating rod 26 is pulled out outward, the first spline 27 remains in a connected state. Therefore, the gear 24 can be driven to rotate by rotating the handle 29 and the rotating rod 26, and thus the height of the ink fountain 19 can be adjusted through the action of the gear 24 and the rack 22. After the adjustment is completed, by pressing the handle 29 inward, the external spline of the second spline 28 is reinserted into the internal spline, so that the rotating rod 26 is fixed on the turntable 15 and cannot rotate, and the height of the ink fountain 19 is fixed through the action of the gear 24 and the rack 22. In the present utility model, the operation of adjusting the height of the ink fountain 19 is simple. Moreover, when the handle 29 is rotated, the two gears 24 rotate synchronously under the action of the connecting rod 25, and the height of the ink fountain 19 is adjusted through the action of the two gears 24 and the rack 22, improving the stability of the ink fountain 19 during movement and fixation.
[0034] The above content described in this specification is only an example of the present utility model. Those skilled in the technical field to which the present utility model pertains can make various modifications or supplements to the described specific embodiments or use similar ways to replace them, as long as they do not deviate from the content of this specification of the present utility model or exceed the scope defined by this claim book, they should fall within the protection scope of the present utility model.
