Working Principle

The 500g Square Sauce Jar Labeling Machine uses a conveyor to feed jars. The separating mechanism spaces out containers, and a photoelectric sensor triggers servo label output. Special positioning fixtures lock square jar angles. Labels stick to jar surfaces and corners, then flexible rollers press out air to complete continuous labeling and output.
