III. Equipment Technical Description
A Roll Forming Support Assembly
The unwinding stand can support rolls up to 300 kg, the automatic pusher reduces the load on the chain for pulling sheets, making it easier to achieve precise sheet feeding.
B Conveying Sheet Material Mechanism
Material for the chain track
Precision-machined from imported high-hardness, wear-resistant aviation aluminum, the track features cooling channels to effectively prevent overheating. The track surface is treated for oxidation, offering corrosion and oxidation resistance over long-term use. It boasts a low friction coefficient, extended service life, and the conveying chain operates flexibly and smoothly within the track.
2. Material conveying track adjustment structure
The track width adjustment is achieved through the principle of a screw mechanism, driven by a motor for quick width adjustment of the two chain tracks. It's all done through high-precision ruler signal input, with the digital motor automatically running for adjustments, eliminating the need for manual human intervention. The precision is as fine as less than 1mm, making it extremely convenient and fast.
3. Method of conveyance
Servo motors accurately control the length of the moving chain, featuring rapid start and stop capabilities, instant high-torque chain pull, and are equipped with high-precision reducers to effectively extend the motor's lifespan.
