[0027] Reference Figure 1-Figure 7 The present embodiment provides a gravure printing test machine, comprising a base 1, a gravure plate roller 3 is arranged on the base 1 through a bracket plate 2, and an ink tank 5 located below the gravure plate roller 3 is arranged on the top of the base 1 through a lifting component 4, a mounting frame 6 is arranged on the top of the bracket plate 2, a pressing roller 7 is arranged on the mounting frame 6 at a position above the gravure plate roller 3, and an adjusting component 8 for separating the pressing roller 7 from the gravure plate roller 3 after the pressing roller 7 rotates one circle is arranged on the mounting frame 6, and a scraper component 9 arranged parallel to the gravure plate roller 3 is arranged on the bracket plate 2.

[0028] In the utility model, the test machine is placed and fixed by a base 1, the substrate passes through between the gravure roller 3 and the embossing roller 7, the ink tank 5 is filled with ink, when the gravure roller 3 rotates, the scraper assembly 9 contacts with the gravure roller 3 on the same straight line, so as to scrape off the excess ink on the gravure roller 3 to ensure the uniformity of the ink, as the gravure roller 3 and the embossing roller 7 rotate, the ink is embossed on the substrate, during the printing process, when the embossing roller 7 contacts with the gravure roller 3 and rotates one circle, the adjusting assembly 8 moves the embossing roller 7 upward to separate it from the gravure roller 3, so that it can be separated after one printing, avoiding the phenomenon of repeated printing, thereby preventing the pattern overlap or blurring caused by repeated printing, and improving the clarity and quality of the printed matter.

[0029] Specifically, Figure 1 and Figure 2 As shown, the adjustment assembly 8 includes an electric cylinder 81 fixed on the top of the mounting frame 6, and the conveying end of the electric cylinder 81 is provided with a mounting seat 83 located inside the mounting frame 6 through a connecting sleeve 82, a bearing is provided in the middle position of the mounting seat 83, and an angle sensor 84 is provided on the mounting seat 83 and sleeved on the outside of the shaft neck of the embossing roller 7.

[0030] When the embossing roller 7 contacts the gravure roller 3 and rotates, the angle sensor 84 detects the rotation angle of the embossing roller 7. After the embossing roller 7 rotates one circle, the angle sensor 84 detects that the embossing roller 7 rotates 360 degrees, thereby controlling the electric cylinder 81 to start. After the electric cylinder 81 starts, it contracts and drives the mounting seat 83 to move upward. The mounting seat 83 has a bearing for the shaft neck of the embossing roller 7 to penetrate. When the mounting seat 83 moves upward, it drives the embossing roller 7 to move upward to separate from the gravure roller 3, so that it can be separated after completing one printing, avoiding the phenomenon of repeated printing.

[0031] It should be noted that the angle sensor 84 uses a sensor model VTA90K30, which can detect angular displacement changes within a stroke of 0 to 360 degrees, meeting the angle detection needs of the embossing roller 7 rotating one circle. The control circuit of the angle sensor 84 and the electric cylinder 81 uses an existing PLC controller. The PLC controller controls the start of the electric cylinder 81 after receiving the detection signal from the angle sensor 84.

[0032] Specifically, Figure 2 As shown, a guide sleeve 85 is fixedly installed on the side of the mounting seat 83, a guide rod 61 matching with the guide sleeve 85 is arranged in the mounting frame 6, an inspection cover 62 is arranged on the side of the mounting frame 6 close to the embossing roller 7, and a slide groove 63 for the shaft neck of the embossing roller 7 to move is opened on the inspection cover 62.

[0033] Among them, the stable movement of the mounting seat 83 is achieved through the guide sleeve 85 and the guide rod 61. When the electric cylinder 81 drives the mounting seat 83 to move, there will be no deviation or tilt. The inspection cover 62 is used for the inspection of the adjustment component 8 inside the mounting frame 6. The slide groove 63 on the inspection cover 62 can meet the movement of the shaft neck of the embossing roller 7 when the electric cylinder 81 drives the mounting seat 83 to move, ensuring that the embossing roller 7 can be driven by the electric cylinder 81 to separate from the gravure plate roller 3 after rotating one circle.

[0034] Specifically, Figure 1 , Figure 3 and Figure 4 As shown, the lifting assembly 4 includes a lifter 41 disposed on the top of the base 1, and a mounting plate 42 for connecting the ink tank 5 is disposed on the top of the lifter 41.
