Description

Technical Field

[0001] Technical Field This utility model relates to the field of screen printing machine technology, and more specifically, to a printing positioning device for a rotary flexible tube screen printing machine. Background Technology

[0002] A flexible tube screen printing machine is a device used to screen print on the surface of flexible tubes. It is widely used in the cosmetics, pharmaceutical, food, and daily chemical industries for printing on products such as cosmetic tubes, pharmaceutical packaging tubes, food packaging tubes, and toothpaste tubes.

[0003] A review of the rotary flexible screen printing machine printing positioning device disclosed in Publication No. CN201784247U reveals that it includes "a printing wheel and a printing gripper, as well as a positioning wheel and a motor-driven rubber wheel. The positioning wheel is connected and fixed to the printing gripper, and a positioning pin is located at the end of the positioning wheel. The rubber wheel is in close contact with the positioning wheel. In this structure, a signal detected by a photoelectric sensor is fed back to a servo motor, which drives the rubber wheel to rotate and rotates the positioning wheel to position the positioning pin. The positioning pin is then locked in place by a positioning clip, ensuring that the printed part is printed at the correct position when it moves to the printing station."

[0004] However, the aforementioned rotary flexible screen printing machine's print positioning device has the following drawbacks:
