A frame-type single twisting machine and its working method

Abstract

The invention relates to a frame-type single-stranding machine. A base is provided with a pair of supports Two, a motor One, a motor Two and a motor Three; a rectangular framework is arranged on the pair of supports Two in a bearing matching manner; each support Two is provided with a bearing seat One; the framework is arranged on the bearing seats One in a rotatable matching manner; wire-leading wheels are arranged in a left-side rectangular frame of the framework in a rotatable matching manner through a rotating shaft; the motor One drives the wire-leading wheels to rotate around the rotating shaft; and the outer circumference of each wire-leading wheel is provided with a plurality of wire slots. A wire coil is arranged in a right-side rectangular frame of the framework in a rotatable matching manner, and the central line of the wire coil is overlapped with the central line of the framework. A wire arranging mechanism used for uniformly winding cable wires on the wire coil is fixedly arranged above the wire coil in the right-side rectangular frame of the framework, the wire arranging mechanism is provided with a wire arranging frame, and the wire arranging frame is provided with a laser range finder One and a laser range finder Two. According to the frame-type single-stranding machine of the invention, the laser range finders are adopted to measure the thickness of wires wound on the wire coil; and through cooperation of the motors and a differential mechanism, precise matching between wire leading speed and wire winding speed can be ensured.

Description

technical field [0001] The invention relates to a frame-type single-twisting machine and its working method. Its main function is to twist two or more metal wires (or plastic-coated metal wires) One or more twisted cables are twisted into cables again and wound on the reel. Background technique [0002] The single-twisting machine is mainly used to twist PE or PVC-coated core wires such as control cables, communication cables, and power lines. It is widely used in the production of twisted wires. There is a speed difference. When the twisting frame is performing the twisting operation, the speed of the twisted wire (lead wire) varies depending on the wire harness and the wire bundle machine. In order not to affect the quality of the twisted wire produced, it is necessary to maintain the winding speed Same as the speed of the twisted wire (lead wire), one of the existing methods is to use a servo motor to adjust the winding speed in real time, but the torque control range of...

[0002] The single-twisting machine is mainly used to twist PE or PVC-coated core wires such as control cables, communication cables, and power lines. It is widely used in the production of twisted wires. There is a speed difference. When the twisting frame is performing the twisting operation, the speed of the twisted wire (lead wire) varies depending on the wire harness and the wire bundle machine. In order not to affect the quality of the twisted wire produced, it is necessary to maintain the winding speed Same as the speed of the twisted wire (lead wire), one of the existing methods is to use a servo motor to adjust the winding speed in real time, but the torque control range of the servo motor is limited, and the cost is high and the programming control is complicated, so it cannot be applied to each twisted wire field; the second existing method is to use a differential to control and adjust the coiling speed, but since the sensor provided cannot measure the thickness of the coiled wire on the coil in real time, the coiling speed cannot be controlled in real time
