Product details
The "non-stop paper feeding machine" (also known as "automatic paper feeder" or "zero-speed paper feeder")Non-stop Rewinding is a crucial automated equipment in the corrugated paperboard production line. It is mainly installed at the unwinding station of the base paper rack. It can automatically complete the replacement and connection of new and old paper rolls without stopping the production line, thus ensuring the continuous and high-speed operation of the corrugated paperboard production line Auto Splicing.
The following are its specific applications and core advantages on the corrugated line:
I. Application Scenarios
Paper/Inner Paper Splicing: At the front stage of the single-sided or double-sided machine in the corrugated paperboard production line, when the original paper roll is about to run out, the paper splicing machine automatically adheres the paper head of the new paper roll (via tape or hot melt adhesive) to the paper tail of the old paper roll, and simultaneously cuts off the old paper to achieve splicing switch.
Core Paper Splicing: This is also applicable to the core paper original paper rack at the corrugated roller position, ensuring continuous and uniform creasing and avoiding creasing breaks caused by paper replacement.
High-speed Line Standard: When the production line speed exceeds 150 meters/minute, manual paper splicing can no longer meet the precision and safety requirements. The paper splicing machine becomes a necessary configuration.
II. Core Advantages
1. Eliminate downtime and significantly increase production efficiency
Traditional manual paper splicing requires a 2-5 minute stop, and multiple paper roll replacements throughout the day result in a significant loss of production time. The automatic paper splicing machine can complete the process at zero speed difference (zero-speed splicing) or at the same speed, without the need to slow down or stop the production line, and the output can be increased by 10%-20%.
2. Reduce waste rate and improve paperboard quality
During the splicing process, the tension is stable, the joint is flat and firm, avoiding common problems such as unevenness, curling, and tension fluctuations in manual splicing. The quality at the joint is better, and subsequent die-cutting and printing processes are less likely to produce defective products.
It reduces defects caused by machine shutdown/restart, such as excessive drying or unevenness, and warping of the paperboard.
3. Save original paper waste
Traditional paper splicing often leaves long paper tails (several tens of meters or even hundreds of meters) that cannot be used. The automatic paper splicing can control the residual tail paper to be in an extremely short range (usually ≤ 5 meters), significantly reducing paper waste.
The success rate of the joint is extremely high (> 99%), further reducing rework losses.
4. Adapt to high-speed and intelligent production lines
Modern corrugated lines have reached speeds of 200-300 meters/minute or even higher. Manual paper splicing is not only dangerous but also cannot guarantee the reliability of the joint. The paper splicing machine can be adapted to high-speed operation and can be linked with the production management system (MES) to achieve automatic splicing, warning of leftover paper, joint counting, and other functions.
5. Reduce labor intensity and safety risks
Workers do not need to operate beside the high-speed rotating equipment, reducing the risk of being caught or cut. At the same time, it reduces the reliance on skilled workers, and ordinary operators can easily manage multiple paper splicing machines.
6. Support more paper types and special processes
For paper types with low weight, high sizing, and high wet strength that are difficult to be spliced manually, the paper splicing machine has more precise pressure and adhesive control, can reliably complete the joint, and expands the range of original paper available for the production line.
III. Summary
Configuring a non-stop paper splicing machine on the corrugated line has changed from "optional upgrade" to "standard configuration for high-speed lines". It not only brings about increased production efficiency and reduced waste, but also fundamentally ensures the stability of paperboard quality and production safety. For paper box enterprises seeking lean production and cost reduction, this is a highly cost-effective technical solution.
