A cup feeding mechanism of a cup printing machine

Abstract

A cup feeding mechanism of a cup printing machine, comprising a frame, a pallet, a turbine, a worm, four fixed shafts, four swing arms, four screw rods, and a drive mechanism capable of driving two adjacent screw rods to rotate in opposite directions; through the four screw rods The screw grooves on the cups are synchronously transported to four points on the opening edge of the cup, and the cup can be more stably and accurately socketed on the cup mold, making the alignment between the cup and the printing device more accurate; The linear guide groove and the arc-shaped guide groove can position the movement track of the roller shaft. Through the adjustment of the worm, the turbine can push the swing arm to swing inside and outside through the roller shaft, thereby adjusting the diameter of the circle surrounded by the four screws. It is suitable for different Specification cup; Since the screw is installed at the end of the long arm of the swing arm, the distance between the screw and the fixed shaft is fixed, and part of the transmission connection on the long arm follows the movement of the long arm. When adjusting the diameter of the circle surrounded by the four screws , without changing any structure of the drive mechanism.

Description

technical field [0001] The invention relates to a printing device, in particular to a cup feeding mechanism of a cup printing machine. Background technique [0002] The cup printing machine generally needs to transfer the cup on the cup storage rack to the cup mold, suck the cup tightly through the negative pressure suction on the cup mold, and then use the cup mold as the support to print the surface of the cup. [0003] Currently, there are two main ways to transfer cups from the cup holder to the cup mold: [0004] (1) Use the cup dividing mechanism to separate the cup at the front of the cup storage rack from the whole stack of cups, and the separated cup falls on the cylindrical cup receiving guide rail (generally surrounded by four guide rods arranged in a circle), and then Cooperate with the air blowing device to blow the cup to move in the cylindrical cup guide rail with the airflow, and finally put it on the cup mold and be sucked by the cup mold. In an improvemen...

Problems solved by technology

This method often sucks two or three cups that are close together at one time, but only the outermost cup can be printed during printing, resulting in inaccurate printing alignment; in addition, it is necessary to set the suction head in the cup mold The driving and guiding structure of the suction head and the suction channel of the suction head must be set, which leads to a complicated structure of the cup mold, and the cup mold often has high precision to ensure the accuracy of printing, but the complicated structure of the cup mold often leads to the Accuracy is reduced, thereby reducing the quality of printing
