Description

Technical Field

[0001] The utility model relates to the technical field of screen printing machines, in particular to a cup feeder for a cup screen printing machine. Background Art

[0002] A cup body screen printer is a machine that prints brand logos and related patterns onto the cup body of disposable cups such as milk tea cups, coffee cups, etc. through a screen printing process. The screen printing process generally includes cleaning the cup body, printing ink, and ink curing. In order to improve the continuity between the various processes, an automated cup body screen printer is generally used. Due to the fast printing speed, the speed of manual loading is difficult to keep up with. Therefore, the cup body screen printer is generally equipped with a cup feeder for automatic cup loading. For example, Chinese utility model patent CN221164586U (publication date 2024.06.18) records a cup feeding device. By setting a rotating block and a positioning rod, the rotation angle of the rotating block can be positioned, thereby achieving the purpose of adjusting the size of the output port surrounded by the screw. The driving mechanism drives each of the screws to rotate simultaneously, so that a single cup can be output forward under the drive of the screw, thereby achieving the purpose of cup feeding. Therefore, there is no need for manual operation of cup separation, and automatic loading is achieved.

[0003] However, the above device has a relatively complex structure, especially the linkage structure for adjusting the size of the output port. In order to achieve the synchronous linkage of multiple rotating blocks, high material processing accuracy is required, and the construction cost and maintenance cost are high. Once a hard object falls into it, the entire feeding device is easily stuck, and the flexibility is low. Utility Model Content
