Three-head four-track double tractor

In 2017, the company invested 2 million yuan to eliminate 5 single tractors to upgrade three-head four-track dual tractors. The single tractor needed to stop the extruder to change rods and cut materials and transfer materials, resulting in low work efficiency and low yield. The three-head four-track double tractor does not need to transfer sawing between the extruder stop and change rods, and it can realize one rod, multiple saws and multiple rods with one saw, and automatically recognizes the rod changing interface for sawing. The operating speed of the double traction machine is much lower than that of the single traction machine, with reliable operation, low failure rate, less mechanical wear and low maintenance costs. The three-head four-track double tractor can increase the extrusion speed by 10-30% (under the condition that the mold strength is satisfied); it can increase the production efficiency by 10-30%; it can increase the yield by 1 to 3%.
