Description
Technical Field
The invention relates to a printing device, in particular to a cup feeding mechanism of a cup printing machine.
Background
The cup printing machine generally needs to transfer a cup on a cup storage rack to a cup mold, suck the cup tightly through negative pressure suction on the cup mold, and then print the surface of the cup by taking the cup mold as a support.
At present, there are mainly two ways to transfer a cup from a cup storage rack to a cup mold:
firstly, a cup separating mechanism is adopted to separate the cup at the forefront of the cup storage rack from the whole stack of cups, the separated cup falls into a cylindrical cup receiving guide rail (generally, four guide rods are arranged circumferentially) and then is matched with a blowing device to blow the cup to move in the cylindrical cup receiving guide rail, and finally the cup is sleeved on a cup mold and is sucked by the cup mold. In an improvement of the mode, a cup pushing mechanism is adopted to replace an air blowing device to push the cup to move along the cylindrical cup receiving guide rail, and the principle is not much. However, although the cylindrical cup receiving guide rail can guide the cup, due to the limitation that the opening diameter of the cup is larger and the diameter of the cup body is smaller, the side surface of the cup body cannot be in contact with the cylindrical cup receiving guide rail in the moving process of a single cup, and only the cup opening is in contact with the cylindrical cup receiving guide rail, so that no matter blowing or pushing is carried out, the cup moves in the cylindrical cup receiving guide rail, the defects of inclination, blocking and the like easily exist, and the defect of inaccurate sleeve joint exists when the cup is sleeved on the cup mold.
And (II) additionally arranging a suction head capable of extending outwards on the cup mold, wherein when the cup mold is aligned with the cup storage frame, the suction head on the cup mold extends outwards, and the cup mold is returned after the cup is sucked and the cup is sleeved on the cup mold. In the mode, two or three cups which are tightly attached together are often sucked at one time, and only the cup on the outermost surface can be printed during printing, so that the printing alignment is not accurate; in addition, a driving and guiding structure of the suction head needs to be arranged in the cup mold, a suction channel of the suction head needs to be arranged, and the like, so that the cup mold is complex in structure, the cup mold always has high precision to ensure the printing accuracy, and the complex cup mold structure always causes the precision of the cup mold to be reduced, so that the printing quality is reduced.
