Disclosure of Invention

The purpose of the invention is as follows:

the empty braid disc blanking and winding device is capable of automatically blanking and winding, accurate in positioning and high in automatic control degree of winding.

The technical scheme is as follows:

the invention provides an empty braid disc blanking and winding device which comprises a blanking mechanism, an inclined rail, a blocking mechanism, a vertical braid winding mechanism, a distance expanding mechanism and a controller. The empty tape coiling disc consists of a disc edge, a frame and a disc core.

The blanking mechanism is positioned at the upper end of the inclined rail and has the functions of storing and releasing the empty braiding discs in a clearance manner, and the inclined rail is used for the released empty braiding discs to move downwards in a sliding manner; the blocking mechanism (a blocking motor and a blocking telescopic rod) is positioned at the lower end of the inclined rail and can block the empty tape weaving disc to avoid the condition that the tape weaving disc slides down too fast and is damaged by collision; the vertical tape winding mechanism (a tape winding motor and a tape winding frame driven by the tape winding motor) has a certain distance (which is related to the diameter of the empty braiding tape disk and the inclination of the inclined rail) between the stopping mechanism and the vertical tape winding mechanism, and the empty braiding tape disk rotates when continuously sliding downwards and is changed into the vertical direction.

The vertical tape winding mechanism (composed of a rotating motor and a tape winding frame) is connected behind the inclined rail, the braiding disk is vertically placed on the inclined rail and can rotate along a horizontal shaft, and the rotating motion is driven by the rotating motor.

The distance expanding mechanism is provided with a distance expanding motor and a distance expanding rod which stretches downwards. The end of the distance-extending rod is in an inverted round table shape, the lower end face of the distance-extending rod is flat, so that the end of the braid can be pressed down conveniently to be tightly attached to a disc core of the braid disc, and the surface of the disc core can have viscosity, so that the end is bonded to the disc core; the diameter of the upper end surface of the distance expanding rod is slightly larger than the distance between the two edges of the braiding disc, so that the distance between the two upper edges of the braiding disc can be expanded, and the braid can easily enter the braiding disc. The diameter of the lower end surface is smaller than the distance between two edges of the braiding belt disk and is basically the same as the width of the braiding belt. (the width of the hub is slightly in an over-fitting relationship with the braid width (preferably negative tolerance, to facilitate gripping of the braid head and to facilitate tight winding of the braid around the hub).

The controller is connected with and controls the start and stop of the blocking motor through a control line, and drives the telescopic rod to be vertical to the blanking inclined rail to generate telescopic action. The center of the disc core is provided with a shaft hole, so that the telescopic rod can be conveniently inserted to realize blocking and positioning, and meanwhile, a rotating shaft of the tape winding frame can penetrate through the shaft hole to realize rotating tape winding. In addition, a sensor A is arranged and used for monitoring the gliding time of the braiding disc.

The sensor B monitors the braid feeding opportunity, signals are transmitted to the controller, and the controller controls the start and stop of the distance extending motor through control line connection to drive the distance extending rod to extend up and down.

Has the advantages that:

the automatic blanking device can realize automatic blanking of the empty braid disc and slide to a proper position; then automatically steering and falling into a belt winding mechanism; the tape winding mechanism can receive the braid at a proper time point, and start the braid from the core disc for tape winding; the ends of the braid are not easy to slip, do not need to be bent, and are tightly wound; through the control of two sensors, the controller controls two motors to accurately start and stop, and the winding automation degree is high and the winding efficiency is high.
