[0005] Offset printing: Offset printing is suitable for flat printing. Although the printing quality is high, it is not suitable for printing on curved surfaces such as bottles. In addition, offset printing equipment is expensive, plate making costs are high, and the scope of application is limited.

The bottle body in this embodiment is a rotating body, and the arc of the clamping block is adapted to the outer contour of the bottle body, and the arc of the bottle mouth clamping block 55 is adapted to the outer contour of the bottle mouth. The clamping cylinder 52 drives the clamping plate 53 to retract inward, so that the bottle body clamping block 54 is 4 fits with the outer contour of the bottle body, and the bottle mouth clamping block 55 fits with the outer contour of the bottle mouth, so as to clamp and fix the bottle body.

[0048] In this embodiment, the printing mechanism 14 adopts a pad printing unit 61 or a screen printing unit. The pad printing unit 61 is used for pad printing on the bottle body, and the screen printing unit is used for screen printing on the bottle body. The screen printing unit in this embodiment is implemented by the existing screen printing method, that is, the dye is placed on the screen plate, and the dye is scraped onto the surface of the bottle body through the hollow pattern on the screen plate with a scraper (not shown in the figure). In particular, see Fig. 9The pad printing unit 61 includes an oil cup 62 and a steel sheet 63 below. The oil cup 62 is in sliding elastic contact with the steel sheet 63 through a first linear module 64 and a spring 65. The pad printing unit 61 also includes a rubber head 66. The rubber head 66 is fixed to one end of an up-and-down moving module 67. The up-and-down moving module 67 is slidably connected to a second linear module 68. The second linear module 68 drives the up-and-down moving module 67 to move horizontally. The up-and-down moving module 67 drives the rubber head 66 to move vertically. The pad printing unit 61 is equipped with a rubber paper conveying mechanism 7. The rubber paper conveying mechanism 7 includes a paper placing shaft 71 and a paper receiving shaft 72. The rubber paper is sleeved on the paper placing shaft 71. The uncovered side of the rubber paper is placed upward. The uncovered end thereof is adhered to the paper receiving shaft 72. The paper receiving shaft 72 is connected to a paper receiving motor 73 adapted to drive the rotation thereof. The rubber head 66 will contact the adhesive paper before each printing cycle to remove the residual ink and impurities on the surface of the rubber head 66, ensure that the surface of the rubber head 66 is clean, prevent the ink from mixing or printing defects during the printing process, and improve the printing quality and consistency. The adhesive paper is intermittently conveyed through the adhesive paper conveying mechanism 7 to ensure that the rubber head 66 contacts a new and clean adhesive paper surface each time. Two pairs of paper pressing shafts 74 are also provided at both ends of the mechanism, and the adhesive paper passes through each pair of paper pressing shafts 74 in turn to achieve the tensioning effect of the adhesive paper. In addition, the rubber head 66 of the pad printing unit 61 in this embodiment adopts a hollow structure. The hollow design makes the rubber head 66 have better flexibility and can better adapt to the curved and irregular surfaces of the bottle body, thereby achieving uniform ink transfer and improving printing quality. The outer surface of the rubber head 66 is a frosted surface. The frosted surface increases the friction when the rubber head 66 contacts the bottle body, prevents slipping, and improves the accuracy and stability of printing.

[0049] See also Fig.10 The printing station is also provided with a support component 8 adapted to the first clamping component 19, and the support component 8 includes a support cylinder 81, the cylinder body of the support cylinder 81 is fixed in the device, and the piston rod 82 of the support cylinder 81 is fixed with two sets of supporting rollers 83 through a connecting rod. When pad printing, the piston rod 82 is retracted, and the supporting rollers 83 move upward and support the bottle body. The rubber head 66 is pressed down to contact the upper surface of the bottle body to generate pressure, which is more conducive to the printing of ink. The support component 8 is also provided with an adjustment stud 85, and the adjustment stud 85 is connected to the adjustment plate 84 fixed to the piston rod 82 through a threaded structure. The support cylinder 81 is provided with a limit switch 86 at one end corresponding to the adjustment stud 85. When the piston rod 82 of the support cylinder 81 is retracted, one end of the adjustment stud 85 contacts the limit switch 86, and the limit switch 86 is activated, so that the piston rod 82 stops extending and retracting, thereby realizing the adjustment of the extension stroke of the support cylinder 81.

[0050] The printing station is also provided with a drying component 9 for drying the ink. The drying component 9 adopts a fire gun, a hot air blower or a combination of the two. The drying component 9 ensures rapid drying of the ink, improves production efficiency, and reduces waiting time. The flame treatment can effectively remove oil stains on the surface of the bottle, ensure the surface is clean before printing, (activate the bottle surface) and improve the ink adhesion, thereby improving the printing quality.
