Abstract
The utility model discloses a round log cutting machine. The round log cutting machine comprises a mechanical mechanism and a hydraulic mechanism, the mechanical mechanism comprises a cutting piston (1), the extending end of the cutting piston (1) is provided with a cutter head (2), and the cutter head (2) is driven by a motor (3); the hydraulic mechanism comprises a proportional velocity regulating valve (6) connected with an oil passage B, the signal output end of the proportional velocity regulating valve (6) is connected with an electric controller (7) through a circuit, and the electric controller (7) is connected with the motor through a circuit. The round log cutting machine is capable of improving the cutting efficiency of the cutting machine and avoiding the equipment failure due to overload.
Description
Technical field
The utility model relates to a kind of circular lumber cutting, relates in particular to a kind of circular lumber cutting that utilizes feedback control technology.
Background technology
Circular lumber cutting is the conventional machinery on Wood Flooring Industry processing floor, existing circular lumber cutting is in the time of the large-scale round log of cutting, cutter plate is with certain speed feeding, along with cutting round log is cut darker and darker, the load that cutter plate is subject to is increasing, now as also, with speed feeding before, be easy to cause cutterhead stuck, even cause burn-down of electric motor.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of circular lumber cutting, and the utility model can improve the cutting effect of cutting machine, can avoid the equipment fault causing due to overload simultaneously.
The technical solution of the utility model: circular lumber cutting, comprise mechanical mechanism and hydraulic mechanism, described mechanical mechanism comprises cutting piston, on the external part of cutting piston, is provided with a cutter plate, cutter plate is driven by motor; Described hydraulic mechanism comprises oil pump, and oil pump is connected with a three position four-way electromagnetic valve through P oil circuit, and the A oil circuit of three position four-way electromagnetic valve is connected with the two ends of cutting piston respectively with B oil circuit, and the T oil circuit of three position four-way electromagnetic valve is connected with fuel tank; On described B oil circuit, be connected with a proportional velocity regulating valve, proportional velocity regulating valve is connected with a proportional valve control amplifier, and proportional valve control amplifier is connected with an electric controller, and electric controller is connected with motor through circuit.
In above-mentioned circular lumber cutting, described electric controller is current transformer.
In aforesaid circular lumber cutting, on described cutter plate, be provided with radiating groove along cutterhead edge ring, radiating groove undulate, the outer end of radiating groove is arranged on circumference place, and the cutterhead center of circle is pointed in the inner end of radiating groove.
In aforesaid circular lumber cutting, on described P oil circuit, be connected with an overflow valve.
Compared with prior art, the utility model is by being arranged on the FEEDBACK CONTROL between proportional velocity regulating valve and the electric controller on B oil circuit, to adjust the feed speed of cutter plate and the cutting load of change cutter plate, reach the constant-speed operation of cutter plate, thereby improve the efficiency of cutting machine, improve cutting accuracy and cutting flatness, also avoided the equipment fault causing due to overload simultaneously.The utility model is also equipped with one group of radiating groove on cutter plate along cutterhead edge simultaneously, and radiating groove can effectively be removed the heat in cutting, promotes cutting effect.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of cutter plate.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further described, but not as the foundation to the utility model restriction.
Embodiment: a kind of circular lumber cutting, as shown in Figure 1, comprise mechanical mechanism and hydraulic mechanism, described mechanical mechanism comprises cutting piston 1, on the external part of cutting piston 1, is provided with a cutter plate 2, cutter plate 2 is driven by motor 3; Described hydraulic mechanism comprises oil pump 4, and oil pump 4 is connected with a three position four-way electromagnetic valve 5 through P oil circuit, and the A oil circuit of three position four-way electromagnetic valve 5 is connected with the two ends of cutting piston 1 respectively with B oil circuit, and the T oil circuit of three position four-way electromagnetic valve 5 is connected with fuel tank; On described B oil circuit, be connected with a proportional velocity regulating valve 6, proportional velocity regulating valve is as can be preferably electro-hydraulic proportional throttle valve, have commercially available, the signal output part of proportional velocity regulating valve 6 is connected with an electric controller 7 through circuit, described electric controller 7 is current transformer, also have commercially availablely, electric controller 7 is connected with motor through circuit.Between described proportional velocity regulating valve 6 and electric controller 7, be provided with proportional valve control amplifier 10, proportional valve control amplifier can adopt conventional amplifier, its function is that current transformer senses that the phase current of motor changes, proportional valve control amplifier amplifies this sensor signal and transfers to proportional velocity regulating valve, passing ratio flow speed control valve is controlled the feed speed of cutting piston, thereby can move when undesired at motor, slow down the feed speed of cutting piston, reduce motor load, make motor recover normal, and the rotating speed that makes cutter plate also recovers normal, realize the constant-speed operation of cutter plate, also danger simultaneously that avoided the normal time anomaly operation of motor to exist.On described P oil circuit, be connected with an overflow valve 9.As shown in Figure 2, on described cutter plate 2, be provided with radiating groove 8 along cutterhead edge ring, radiating groove 8 undulates, the outer end of radiating groove is arranged on circumference place, and the cutterhead center of circle is pointed in the inner end of radiating groove.
