[0042] In the description of the present application, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present application.

[0043] Example

[0044] In order to solve the problem that the flexible printing machine in the prior art cannot flexibly adjust the angle formed by the ink scraper and the anilox roller 24 and fine-tune the distance between the ink scraper and the anilox roller 24, resulting in poor printing quality and failure to quickly dry the pattern on the substrate, resulting in a series of subsequent problems, reference is made to Figure 1-Figure 5 As shown, in some embodiments, the present application provides a flexible printing machine, which mainly includes a machine platform 10, an ink supply mechanism 20, an ink scraping mechanism 30, a printing mechanism 40 and a drying mechanism 50;

[0045] The ink supply mechanism 20 includes an ink basin 21 disposed on the upper left side of the machine platform 10, an ink roller 22 rotatably disposed within the ink basin 21, two first supports 23 disposed on the machine platform 10 at the front and rear sides of the ink basin 21, and an anilox roller 24 rotatably disposed between the two first supports 23 and in contact with the ink roller 22.

[0046] Specifically, since the anilox roller 24 is in contact with the ink roller 22 , when the ink roller 22 rotates, the ink in the ink basin 21 will be transferred to the anilox roller 24 ;

[0047] The ink scraping mechanism 30 includes a gantry 31 rotatably mounted above the right side of the ink basin 21, a tilt adjustment unit 32 mounted on the front side of the machine 10 and connected to the gantry 31, an elastic telescopic adjustment unit 33 mounted above the crossbeam of the gantry 31 and corresponding to the anilox roller 24, and an ink scraper 34 connected to the elastic telescopic adjustment unit 33 and in contact with the anilox roller 24.

[0048] Specifically, before performing printing, the operator can adjust the inclination angle of the gantry 31 by operating the inclination adjustment unit 32 to adjust the angle of the ink scraper 34, and adjust the distance between the ink scraper 34 and the anilox roller 24 through the elastic telescopic adjustment unit 33 to ensure that the anilox roller 24 achieves a better ink scraping effect and does not cause damage to the ink scraper 34.

[0049] The printing mechanism 40 includes a base 41 disposed on the machine platform 10 to the right of the ink basin 21, a plate roller 42 rotatably disposed below the base 41 and in contact with the anilox roller 24, a flexographic plate 421 adhered to the surface of the plate roller 42, and a pressure roller 43 rotatably disposed above the base 41 and spaced apart from the plate roller 42.

[0050] Specifically, since the flexible plate 421 on the plate roller 42 is adhered with ink, when the substrate passes through the pressure roller 43 and the plate roller 42, the flexible plate 421 on the plate roller 42 will automatically print the corresponding pattern on the substrate;

[0051] The drying mechanism 50 includes a drying seat 51 located above the right side of the machine 10 and corresponding to the plate roller 42, a paper feed slot 511 extending transversely through the drying seat 51, and a drying unit 52 located at the bottom of the paper feed slot 511.

[0052] Specifically, after the pattern on the substrate is printed, it passes through the paper feed slot 511 in the drying seat 51. During this process, the drying unit 52 located at the bottom of the drying seat 51 will quickly dry the pattern on the substrate. In this way, the pattern will not be damaged when the substrate enters subsequent processing.

[0053] As an example, the present application provides a U-shaped seat a35 on the front and rear sides of the ink basin 21 of the machine 10, and the two legs of the door frame 31 are respectively rotatably connected to the two U-shaped seats a35 through the first shaft 322. Based on this structure, the tilt adjustment unit 32 of the present application includes a rotating support 321, a large gear 323, a small gear 324 and a second shaft 325. The large gear 323 is connected to the first shaft 322 on the outside of the U-shaped seat a35 corresponding to the front side. The rotating support 321 is set on the front side of the machine 10. The small gear 324 is rotatably connected to the rotating support 321 through the second shaft 325 and is meshed with the large gear 323, and a knob 326 is provided at the end of the second shaft 325. When the operator adjusts the angle of the door frame 31, the operator manually rotates the knob. At this time, the large gear 323 is driven to rotate by the small gear 324. In this way, the door frame 31 will rotate within the two U-shaped seats a35, and the operator can reduce the force when driving the small gear 324 to rotate by the knob, which is more convenient to use.

[0054] As an example, the flexible telescopic adjustment unit of the present application includes a square column 331, a screw 332, a spring 334, a pressure block 33 and a telescopic rod 335. The square column 331 is arranged above the crossbeam of the door frame 31. A circular cavity 3311 is provided inside the square column 331. A step 3312 is provided on the inner wall of the circular cavity 3311. The pressure block 33 is arranged inside the circular cavity 3311. The screw 332 is screwed into the circular cavity 3311 on the outside of the square column 331 and connected to the pressure block 33. The telescopic rod 335 extends from the bottom of the square column 331 into the circular cavity 3311, and the top of the telescopic rod 335 is provided with a step 3312. The part is provided with a limit, and the spring 334 is arranged between the limit and the pressure block 33. When the operator adjusts the distance between the ink scraper 34 and the anilox roller 24, the operator drives the pressure block 33 to rise and fall in the circular cavity 3311 by twisting the screw 332. During this process, the spring 334 will press the telescopic rod 335 to elastically expand and contract until the ink scraper 34 is in the ideal position. In addition, the present application can ensure that the ink scraper 34 has a slight elastic expansion and contraction by setting the spring 334 to press the telescopic rod 335. In this way, the ink scraping quality is guaranteed and the anilox roller 24 is protected, which has high practicality.

[0055] Based on the above scheme, in order to quickly disassemble and assemble the ink scraper 34 and the telescopic rod 335, the present application has a U-shaped seat b341 integrated above the ink scraper 34, and a first mounting screw hole is provided on both side walls of the U-shaped seat b341, and a second mounting screw hole is provided below the telescopic rod 335. When the ink scraper 34 and the telescopic rod 335 are installed, the telescopic rod 335 is inserted into the inside of the U-shaped seat b341 and a bolt 36 is screwed into the outside of the U-shaped seat b341 through the first mounting screw hole and the two second threaded holes, and the bolt 36 fixes the telescopic rod 335 to the U-shaped seat b341 and a nut 37 is screwed on the other end.

[0056] As an example, the drying unit 52 includes several UV lamps 521, and the inner walls on both sides of the wiring trough 511 are respectively provided with overlapping steps 512. Several UV lamps 521 are arranged side by side at the bottom of the wiring trough 512. When the printed substrate passes through the overlapping steps 512 of the paper feed trough 511, several UV lamps 521 emit strong light to the substrate, which can quickly dry the pattern on the substrate.

[0057] In addition to the above structure, the present application further includes a first drive mechanism 60, which includes a first reduction motor 61. The first reduction motor 61 is disposed on an outer side of the ink basin 21 and is connected to the ink roller 22. Driven by the first reduction motor 61, the ink roller 22 of the present application rotates in the ink basin 21.

[0058] And the second driving mechanism 70, the second driving mechanism 70 includes a second reduction motor 71, a first gear 75, a second gear 76, a first pulley 72, a second pulley 73 and a transmission belt 74, the second reduction motor 71 is arranged at the lower front side of the base 41 and its output shaft is connected to the plate roller 42, the first pulley 72 is installed on the output shaft of the second reduction motor 71, the first pulley 72 is connected to the plate roller 42 at the upper front side of the base 41, and the transmission belt 74 is wound around the first pulley 72 and the second pulley 73 On the upper side, the first gear 75 is connected to the printing plate roller 42 at the lower outer portion of the rear side of the machine base 41, and the second gear 76 is connected to the anilox roller 24 at the outer portion of the first pillar 23 corresponding to the rear side, and the first gear 75 is meshed with the second gear 76. Driven by the second reduction motor 71, the printing roller can rotate directly. Driven by the transmission belt 74, the first pulley 72 and the second pulley 73, the pressure roller 43 will also rotate synchronously, and with the cooperation of the first gear 75 and the second gear 76, the anilox roller 24 will also rotate synchronously.

[0059] The present application further includes a first guide mechanism 80, which includes a stand 81 and a first guide roller 82. The stand 81 is disposed on the machine platform 10 at the rear of the machine base 41. The first guide roller 82 is rotatably disposed on the stand 81 on a side facing the machine base 41. In actual use, the dried substrate will pass through the first guide roller 82.

[0060] It also includes a second guide mechanism 90, which includes a second guide roller 92 and two second pillars 91. The two second pillars 91 are respectively arranged on the front and rear sides of the machine 10 close to the drying seat 51. The second guide roller 92 can be rotatably arranged between the two second pillars 91. In actual use, the substrate to be printed will pass through the second guide roller 92.
