Synchronous tractor system and synchronous control method

Abstract

The invention discloses a synchronous tractor system. The synchronous tractor system comprises an upper roll, a lower roll, gears, gear shafts, a cross connector and a traction motor; the synchronous tractor system is provided with a driving system, a driven system and a synchronous control device; the driving system drives a chain wheel through a speed reducer, the chain wheel drives the lower roll, the lower roll drives a lower gear, and the lower gear drives an upper gear so as to achieve up-and-down synchronous transmission; the driven system directly drives the lower roll, the lower roll drives the lower gear, and the lower gear drives the upper gear so as to achieve the up-and-down synchronous transmission; the synchronous control device synchronously controls the driving system and the driven system so as to ensure achievement of the up-and-down synchronous transmission. The synchronous tractor system overcomes the defect of the existing hollow board tractor; through adoption of the up-and-down transmission, the synchronous transmission of the upper roll and the lower roll is achieved during transmission of the speed reducer, so that continuous synchronization can be achieved, traction slipping is avoided, friction is increased, and the production efficiency is greatly improved.

Description

technical field [0001] The present invention relates to the technical field of traction mechanical devices, in particular to a synchronous tractor system and method Background technique [0002] At present, many tractors in the prior art only have power for the lower roller, and the upper roller is passive. Because a reducer drives the sprocket, and then drives the teeth of the lower roller to rotate, the upper roller cannot be pressed very tightly with the lower roller during work, and the compression is easy to cause deformation of the hollow plate. This has caused the upper roller to slip when it cannot be pressed tightly, and the lower transmission gear is a spur gear, the transmission gap is relatively large, and errors follow. [0003] And some hollow plate tractors in the prior art also have the dual power drive system that upper and lower rollers have power respectively, and corresponding synchronizing device thereof. However, the parameter setting of the PID contr...
