[0016] The present invention will now be described in further detail with reference to the accompanying drawings.

[0017] like Figure 1 As shown, the automatic printing machine for multi-curved surfaces of glassware 5 mainly includes a frame 1. A rotating mechanism 2 is installed at the lower part of the frame 1, and six clamping mechanisms 3 that can rotate with it are installed on the rotating mechanism 2. The clamping mechanisms 3 are used to clamp the glassware 5. Four printing mechanisms 4 are installed on the upper bottom surface of the frame 1. The printing mechanisms 4 are used to clamp the pigment plate and perform printing. The four printing mechanisms 4 are located directly above the four clamping mechanisms 3 that are close to each other.

[0018] like Figure 2 As shown, four vertical mounting rods 11 are provided on the upper bottom surface of the frame 1, and each printing mechanism 4 is installed on each mounting rod 11.

[0019] Preferably, the bottom ends of each mounting vertical rod 11 are connected by multiple connecting strips 12, thereby improving its structural stability.

[0020] like Figure 3As shown, the rotating mechanism 2 includes a hollow rotating platform 21, which is installed at the lower part of the frame 1. A rotating disk 22 is installed on the hollow rotating platform 21. The operation of the hollow rotating platform 21 can cause the rotating disk 22 to rotate around its own central axis.

[0021] It can be assumed that six workstations are evenly distributed on the circumference of the rotating disk 22, and the rotating disk 22 rotates by an angle of 60 degrees each time, which is equivalent to rotating the position of one workstation. Among them, let the four workstations where the clamping mechanisms 3 are located below the printing mechanism 4 be called working stations, and the two workstations where the clamping mechanisms 3 are not located below the printing mechanism 4 be called loading stations and unloading stations, respectively. Then the loading stations and unloading stations are close to each other.

[0022] Preferably, a rotating support 23 is installed in the center of the rotating disk 22, and a slip ring 24 is installed on the top of the rotating support 23. The slip ring 24 ensures the transmission of energy and signals to the hollow rotating platform 21.

[0023] Preferably, multiple distribution boxes 25 are installed on the rotating disk 22, which can be used to house equipment such as electricity meters and wires.

[0024] like Figure 4 As shown, the clamping mechanism 3 mainly includes a rotary motor 31, a clamping cylinder 32, a fixed clamping block 33, and a movable clamping block 34. The rotary motor 31 is mounted on the rotating disk 22. The clamping cylinder 32 and the fixed clamping block 33 are both connected to the rotor of the rotary motor 31. The rotary motor 31 enables the movable cylinder and the fixed clamping block 33 to rotate in a vertical plane. The movable clamping block 34 is connected to the piston rod of the clamping cylinder 32 and is arranged opposite to the fixed clamping block 33. The operation of the clamping cylinder 32 can push the movable clamping block 34 closer to or further away from the fixed clamping block 33, thereby clamping the glassware 5.

[0025] A rotating mounting base 35 is installed at one end of the fixed clamping block 33, and a rotating motor 36 is installed at the other end. The rotating mounting base 35 and the rotating motor 36 are connected by a belt drive mechanism 37 consisting of a belt and a pulley. The rotating mounting base 35 can be used to cooperate with the movable clamping block 34 to clamp the glassware 5, and the operation of the rotating motor 36 can drive the rotating mounting base 35 to rotate through the belt drive mechanism 37, thereby causing the glassware 5 clamped on it to rotate together to cooperate with the printing work.

[0026] Preferably, the rotary motor 31 is mounted on the station of the rotary disk 22 via a mounting block 38.

[0027] Preferably, the rotor of the rotary motor 31 is connected to a mounting frame 39, the clamping cylinder 32 is installed inside the mounting frame 39, and the fixed clamping block 33 is connected to the outside of the mounting frame 39.

[0028] When using the clamping mechanism 3 to clamp the glassware 5, firstly, the rotary motor 31 of the clamping mechanism 3 at the loading position is operated to drive the rotary mounting seat 35 on the fixed clamping block 33 to rotate upwards; then the glassware 5 is installed on the rotary mounting seat 35, and then the clamping cylinder 32 is operated to move the clamping block 34 closer until it cooperates with the fixed clamping block 33 to clamp the glassware 5; then the rotary motor 31 is operated to drive the fixed clamping block 33 to return to its original position, so that the rotation of the rotating disk 22 can drive the rotating mechanism 2 to pass through each processing position in sequence, and cooperate with each printing mechanism 4 to print on the glassware 5; finally, when it reaches the unloading position, the rotary mounting seat 35 can be rotated upwards again and the moving clamping block 34 can be moved away, so that the printed glassware 5 can be removed.

[0029] like Figure 5 As shown, the printing mechanism 4 includes a vertical electric slide 41, which is mounted on the mounting rod 11. A height-adjustable printing head 42 and an adjustable clamp 43 are slidably mounted on the vertical electric slide 41, and the adjustable clamp 43 holds a pigment plate. The printing head 42 is located directly above the pigment plate, and the pigment plate is located directly above the glass container 5 held by the clamping mechanism 3.

[0030] Preferably, a vertical connecting plate 44 is slidably mounted on the vertical electric slide table 41, and the printing head 42 and the pigment plate are both connected to the vertical connecting plate 44.

[0031] In a further preferred embodiment, the printing head 42 is connected to a lifting cylinder 45, which can be raised and lowered under the operation of the lifting cylinder 45, and the lifting cylinder 45 is connected to the vertical connecting plate 44.

[0032] In a further preferred embodiment, the adjusting chuck 43 is connected to an adjusting screw 46, which is slidably mounted on a horizontal slide rail 47 and connected to a sliding motor 48. The horizontal slide rail 47 is connected to a vertical connecting plate 44. Thus, the horizontal position of the adjusting screw 46 and the adjusting chuck 43 can be adjusted by the sliding motor 48, while the width of the adjusting chuck 43 can be adjusted by the adjusting screw 46 to accommodate pigment plates of different sizes.

[0033] When printing on glassware 5 using printing mechanism 4, the glassware 5 held by clamping mechanism 3 is moved to the bottom of pigment plate and rotated. Printing head 42 descends and presses pigment plate onto the surface of glassware 5, thus printing work is carried out on the surface of glassware 5 in conjunction with its rotation.

[0034] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
