Hydraulic control system for log cutting machine

Abstract

The invention discloses a hydraulic control system for log cutting machines. The hydraulic control system comprises a mechanical mechanism and a hydraulic mechanism, wherein the mechanical mechanism comprises a cutting piston (1); a cutting cutter head (2) is arranged at the extension end of the cutting piston (1); the cutting cutter head (2) is driven by a motor (3); the hydraulic mechanism comprises a proportional velocity regulating valve (6) which is connected to an oil way B; the signal output end of the proportional velocity regulating valve (6) is connected with a proportional valve control amplifier (8) through a circuit; the proportional valve control amplifier (8) is connected with an electric controller (7); the electric controller (7) is connected with the motor (3) through a circuit. According to the hydraulic control system for the log cutting machines, the cutting efficiency of the cutting machines can be improved and the equipment failure caused by overload can be also avoided.

Description

technical field [0001] The invention relates to a hydraulic control system for a log cutting machine, in particular to a hydraulic control system for a log cutting machine using feedback control technology. Background technique [0002] The log cutting machine is a common machine for processing floors in the wood flooring industry. When the existing log cutting machine cuts large logs, the cutting disc is fed at a certain speed. As the cutting log gets deeper and deeper, the cutting disc The load received is getting bigger and bigger. If you still feed at the previous speed at this time, it is easy to cause the cutter head to be stuck, and even cause the motor to burn out. At present, the industry is researching a system that realizes the constant speed operation of the cutting cutter head by controlling the feeding hydraulic mechanism of the cutting cutter head and the feedback control of the motor and other mechanical mechanisms. However, the existing research on the hydra...

[0002] The log cutting machine is a common machine for processing floors in the wood flooring industry. When the existing log cutting machine cuts large logs, the cutting disc is fed at a certain speed. As the cutting log gets deeper and deeper, the cutting disc The load received is getting bigger and bigger. If you continue to feed at the previous speed at this time, it is easy to cause the cutter head to be stuck, and even cause the motor to burn out.

At present, the industry is researching a system that realizes the constant speed operation of the cutting cutter head by controlling the feeding hydraulic mechanism of the cutting cutter head and the feedback control of the motor and other mechanical mechanisms. However, the existing research on the hydraulic mechanism is relatively immature, so the improvement Existing hydraulic mechanism has become a problem to be solved urgently in this field
