Here are the details of cutting reels into flat sheets, including how machines operate and how to control quality:

Machine Implementation

● Unwinding Mechanism: The paper reel is mounted on an unwinding shaft, driven by a motor with a tension control system to unroll the paper at a stable speed and appropriate tension, preventing wrinkling or stretching.

● Positioning System: Photoelectric sensors or laser positioning devices are used to accurately detect the paper edge or specific marks, sending signals to the control system to determine the cutting position and ensure dimensional accuracy.

● Cutting Device: Common cutting machines include rotary blade cutters and straight blade cutters. Rotary blade cutters use high-speed rotating circular blades for cutting, suitable for high-speed, large-batch production; straight blade cutters use linear-moving blades for higher cutting precision, ideal for applications requiring strict accuracy.

● Conveyor Mechanism: Cut flat sheets are transported to designated positions via conveyor belts or rollers, with alignment devices to ensure neat arrangement during transportation.

● Catering industry: Disposable paper cups (for cold and hot drinks), noodle bowls, soup buckets.

● Takeout packaging: oil-splashed noodle boxes, fried chicken boxes, French fries cups, salad bowls.

● Food retail: baking packaging, fresh food trays, outer packaging for frozen foods.
