QMJ175M4 AI Longitudinal Optimizing Saw Line

Product Details

Highlights

The QMJ175M4 AI Longitudinal Optimizing Saw Line is designed for intelligent longitudinal ripping and width optimization of solid wood boards. It combines visual scanning, real-time cutting optimization, servo positioning, automatic longitudinal feeding and multi-blade sawing in one integrated production system.

The visual scanning system measures board dimensions and identifies knots, cracks, color variations, edge defects and usable material areas. Optimization software then calculates the most efficient longitudinal cutting plan before the workpiece enters the saw. Four movable saw blades automatically adjust to the optimized cutting widths, while one fixed blade provides a stable cutting reference.

Automatically detect the total width of the board,the position and width of the edge trim,the available width,and the board length (within the grating detection range).
After the wood is conveyed to the feeding area, the equipment automatically calibrates the position of the wood according to the optimal selection plan, ensuring it is accurately positioned at the preset feeding station.
The feeding pressure roller presses down smoothly, ensuring the wood is fed into the multi-blade saw accurately and stably for precise cutting.
4-moving saws: can be flexibly adiusted according to the actual size and needs of the board to achieve the optimalplate cutting solution. 1-fixed saw: provides a stable reference for the entire cutting process, ensuring cutting accuracy.
Discharge Roller Mechanism
The movable pressure shoe can adapt tothe real-time position and movement of thewood. It also has anti-tear function.
Six sets of air-floating press rollers can ensure that the material is under uniform pressure on multiple levels, and can adapt to different materials, thicknesses and widths, with strong adaptability and flexibility.
Double-diamond guide rails provide stable support and guidance, ensuring the smoothness and accuracy of the wood during transmission.
The design of the transport chain with spikes takes into account factors such as the shape, size and weight of the wood to ensure that the wood does not slip or shift during transmission.

Features

The intelligent visual scanning system measures board width, length, edge-trimming position and usable material area while detecting visible defects before longitudinal cutting.
Four movable saw blades automatically adjust according to the optimized rip-cutting plan, while one fixed saw blade provides a stable reference for consistent cutting accuracy.
The servo positioning mechanism automatically aligns each board with the selected cutting pattern before feeding it into the multi-blade saw.
Six air-floating pressure rollers, a follow-up pressure plate and a spiked feeding chain keep materials stable and reduce slipping, shifting and edge tearing during high-speed processing.
Double diamond-shaped guide rails provide stable support and accurate longitudinal feeding, while optional infeed and discharge systems allow integration into a complete automated production line.

Automations

The AI Vision Optimizing Rip & Cross-Cut Production Line is an integrated solid wood processing solution combining visual defect scanning, longitudinal optimization, ripping, cross-cut scanning and automatic cross-cut optimization.
At the front end, the QMF4000 Vision Scanner scans the wood surface and identifies defects and usable areas for longitudinal optimization. The material is then transferred to the QMJ175M4 Rip Saw, where it is accurately ripped according to the optimized cutting solution.
After longitudinal processing, the ripped strips enter the QEC500 Cross-Cut Vision Scanner, which performs a second visual inspection and determines the optimal cross-cutting positions based on defects, required lengths and yield targets.
Finally, two MJ255A Optimizing Cross-Cut Saws automatically execute the cutting instructions, allowing high-speed parallel processing and maximizing material utilization.
The complete line connects vision scanning, intelligent optimization, ripping and cross-cutting into one continuous automated process, helping solid wood manufacturers increase yield, reduce manual inspection, improve cutting consistency and achieve higher production efficiency.
