AI Technical Summary
In existing technologies, when rolls of paper or fabric enter the printer, insufficient roller tension causes the entry speed to be lower than the preset required speed, resulting in misaligned printed patterns. Furthermore, the raw materials need to be cut to meet the requirements, increasing labor and time, and resulting in low printing efficiency.
The system employs a combination of a floating pressure roller and a lifting counterweight device. When the printer is not printing, the floating pressure roller moves down to press the material, and moves up to release it when printing. The lifting counterweight device controls the up and down movement of the floating pressure roller, reducing the resistance to the material entering the printer and ensuring that the material enters at a preset speed.
It enables raw materials to enter the printer inlet at a preset speed, eliminating the need for cutting, avoiding pattern misalignment, reducing labor and time, and improving printing efficiency.
