Abstract

The pump(2) of the motor(1) extrudes oil. A pressure control valve(3) controls the oil flowrate by a pre-adjusted highest oil pressure. Th oil flow direction extruded from the valve(4) is controlled by a direction control valve(5). This oil flows through a flowrate control valve(6) and a valve(7) and reaches a control valve(8). This control valve controls the textile drawing roller (9) by its textile amount. The control valve extrudes a small amount of oil when the load of the roller is low and vice versa. By this means, this control valve regulates the roller speed automatically. The remaining oil extrudes through the over valve (11).

The present invention connects a hydraulic automatic speed regulating power unit to a winding roller of a high pressure jigger dyeing machine in the fiber dyeing machine, thereby eliminating the factors of acceleration or deceleration caused by the difference in diameter of the winding amount by a conventional gear mechanical power unit. By automatically adjusting the rotational speed of the winding roller by a certain value, it is possible to proceed at a constant rate at all times without any difference in the rotational ratio of the winding amount during the process of repeatedly rotating the fabric to both rollers during dyeing. The present invention relates to a hydraulic automatic speed control power unit for a textile machine, which is installed to perform uniformly and efficiently.

In the conventional high pressure Zica dyeing machine, the rotation of the winding roller is rotated at a constant speed as the A.C motor by the gear mechanical type, so the constant acceleration and deceleration is controlled by the difference in the rotation rate according to the winding amount of the two winding rollers on both sides. Because of this difficulty, the tension of the fiber could not be maintained at a constant value, so there was a problem that the dyeing process should be repeated several times.

Therefore, the speed control was planned by using the driving force of D. C motor V. S motor, etc., but it was not able to solve the problem of acceleration or deceleration of constant value so far, so it could not improve the efficiency of dyeing work.

The hydraulically controlled power unit of the present invention is controlled at a constant rate by automatically adjusting the difference according to the winding amount of both winding rollers by a hydraulic control valve, so that the fiber is immersed in the salt container during dyeing operation at a constant rotational speed at all times. Because it keeps the color of the dyeing, there is no difference in color (stain and density), reducing the dyeing work 1-2 times, no impact vibration noise to the machine, extending the life of the machine, shortening working time and rotating according to the winding amount Since the number is set to a number, the workforce can be reduced, such that the worker can work with other machines.

Therefore, the operation principle of the present invention will be described with reference to the circuit diagram as follows.

The pump (2) installed on one side of the motor (1) sends oil and adjusts the maximum pressure value in advance according to the amount of fabric to be dyed with the pressure regulating valve (3). The oil discharged by (4) is controlled by the direction change indication valve (9). The oil is then passed through the check valve (7) through the flow control valve (6) and the pressure setpoint adjustment. After reaching the control valves (8) and (8 '), the winding amount of both winding rollers (9) and (9') is large on one side by the function of balancing the mutual pressure of the copper control valves (8) and (8 '). The other side is to equalize the difference in the number of revolutions proportional to the smaller.

Therefore, when the load from the two-sided rollers 9, 9 'is large due to the oil discharged from the hydraulic motor 10, the oil is discharged by the control valves 8 and 8' with a small amount of oil and when the load is low, the amount of oil is increased. The rotational speeds of both rollers are adjusted to each other at a constant value, and the surplus flow rate is discharged from the overvalve 11.

Thus, after winding in the rotation direction, it is continuously and repeatedly operated by the electronic device installed separately, and it is automatically made at a certain rate of rotation speed without accelerating or decelerating according to the winding amount of both rollers. Since it can be carried out as a conventional invention, it is an advantageous invention that can solve all the causes of the dyeing defects caused by excessive tension without being rotated at a constant speed due to the difference in the diameter of the winding amount in the gear machine and perform the work efficiently.
