Automatic Paper Cup Lid Making Machine For Takeaway Food Container

PR-D-125 paper Cup Lid Making Machine is widely used in ice cream cups, soup cups, coffee cups, etc. The base material used in paper cover machine is paper sheet, while the base material used in paper cover on the market is paper tube, paper tube requires more supporting equipment, compared to this paper cover machine can significantly reduce production costs and simplify the production process.

1. Material Feeding

The process starts with feeding the machine with paper rolls. These rolls are typically made from PE-coated paper or other food-grade paper materials. The machine is designed to handle multiple layers, usually three, to form a sturdy lid.

2. Layering and Gluing

The machine aligns the three layers of paper and applies adhesive between them to bond the layers together. This step is crucial for creating a strong, leak-resistant lid. The gluing process must be precise to ensure that the layers are evenly bonded without excess glue that could affect the final product's quality.

3. Heating and Forming

After the layers are glued together, the multi-layered paper is fed into a heating station. The heat activates the adhesive, ensuring a strong bond between the layers. Once heated, the paper moves to the forming station, where it is molded into the shape of the lid using specially designed dies.

4. Cutting

 The formed lids are then cut from the paper sheet. The cutting process is done with precision dies that ensure each lid is cut to the exact size and shape required. The cutting process also ensures that the edges are smooth and properly sealed to prevent any leakage when the lid is used.

5. Edge Curling

After cutting, the machine curls the edges of the lids. This curling process is essential to give the lid its final shape, making it easier to fit onto cups and bowls securely. The curled edge also adds to the lid's structural integrity.

6. Stacking and Counting

 The finished lids are automatically stacked in neat piles by the machine. During stacking, the machine counts the lids to prepare them for packaging. This feature ensures that the lids are organized and ready for bulk packaging.

7. Quality Inspection

Throughout the process, the machine is equipped with sensors and quality control systems that monitor the production. These systems check for consistency in lid size, shape, bonding strength, and overall quality to ensure that each lid meets the required standards.

8. Waste Collection and Recycling

 Any excess material or waste generated during the cutting process is collected by the machine. This waste can often be recycled, contributing to an environmentally friendly production process.

9. Packaging

The final step is the packaging of the finished lids. The machine can either integrate with a packaging unit or the lids can be manually packed, depending on the production setup. The lids are typically packed in bulk for distribution.
