Working Principle The basic workflow of PET cup sleeve machine is as follows: 1. Feeding: Empty cups are transported into the working area of the sleeve machine via a conveyor belt. 2. Label Pickup: An automatic label pickup system extracts the labels from a roll. 3. Label Application: The label is softened using hot or cold air and then applied to the cup. 4. Shrink and Set: The applied label is heated using a hot air gun or shrink tunnel to ensure it tightly adheres to the surface of the cup. 5. Inspection and Packaging: The final product is inspected for quality before being sent to the packaging section. Main Components 1. Frame: The main structure of the machine, usually made of stainless steel and aluminum alloy, offering good corrosion resistance and stability. 2. Conveyor System: Comprising conveyor belts and drive mechanisms, responsible for transporting cups to different stations. 3. Label Supply System: Includes the label roll and cutting device, ensuring stable label supply. 4. Labeling Device: Mechanically or thermally applies the label to the cup. 5. Hot Air System: Used to heat the applied label, causing it to shrink and adhere to the cup. 6. Control System: Typically utilizes a PLC (Programmable Logic Controller) to automate operations and monitor data. Application Areas PET cup sleeve machines are widely used in the following industries: Beverage Industry: Such as water, juice, carbonated drinks, etc. Dairy Products: Such as yogurt, milk tea, etc. Daily Chemicals: Such as shampoo, body wash, etc. Other Packaging: Such as pharmaceuticals, health products, etc. Purchasing Suggestions 1. Production Capacity Needs: Choose a machine that meets the required production capacity for the production line. 2.
