Wire pushing structure of automatic glass fiber cylinder changing wire drawing machineTechnical Field
The invention relates to the technical field of glass fiber production equipment, in particular to a wire pushing structure of a glass fiber automatic cylinder changing wire drawing machine.
Background
The glass fiber drawing machine is mechanical equipment for drawing glass solution into fibers and winding the fibers into fiber rolls according to a certain rule, most of the glass fiber production processes adopt a double-machine-head automatic cylinder-changing drawing machine, which is also called a double-cylinder automatic cylinder-changing drawing machine, and Chinese patent application No. 201120325987.6 discloses a separating and drawing structure of the glass fiber automatic cylinder-changing drawing machine, which comprises a cylinder-changing turntable, a rotating machine head and a pushing screw rod, wherein a winding displacement mechanism is arranged above the side of the rotating machine head and comprises a winding displacement shaft, a winding displacement steel wire and a wire blocking screw rod; the wire arrangement mechanism is provided with a wire avoidance driving mechanism which can drive the wire arrangement mechanism to be far away from or close to the wire arrangement starting point. When the cylinder is replaced, the wire arrangement mechanism is driven by the wire avoidance driving mechanism to be far away from the initial position, the pushing screw rod pushes all the bundles of glass fibers outwards from the winding position to exchange the positions of the rotating machine head, and all the bundles of glass fibers are wound on the wire winding cylinder of the rotating machine head; after the wire arrangement mechanism is reset, all bundles of glass fibers enter gaps of the wire arrangement steel wires again under the guidance of the wire blocking rod to continue wire arrangement, so that full-automatic cylinder replacement of the double-split wire drawing machine is realized. The double-winding tube or multi-winding tube split drawing on the rotary machine head can be realized while the automatic tube changing is realized, and the scheme realizes multi-tube split drawing, as shown in fig. 1, the displacement of the 3# fiber close to the push rod is larger due to the fact that the push rod is parallel to the axis of the machine head, and the situation that the fiber breaks due to overlarge tension is easy to occur.

By adopting the technical scheme, the push rod is placed in the vertical direction of the axis of the machine head, so that the distance between the push rod and the plurality of groups of fiber yarns is equal, the tension of each group of fiber subjected to the push rod is always consistent in the fiber push process, the situation that the tension of a certain group of fiber is overlarge to cause fracture is avoided, and the quality and the efficiency of wire drawing are improved.
Further, the automatic wire arranging device further comprises a horizontal chute which is arranged on the frame and is perpendicular to the axis of the rotating machine head, a supporting plate which is connected with the chute in a sliding manner is arranged in the chute, the wire arranging mechanism is arranged on the supporting plate, a driving wire avoiding mechanism is arranged on the supporting plate, and a driving mechanism which drives the supporting plate to slide in the chute is arranged on the frame.
By adopting the technical scheme, the driving mechanism drives the supporting plate to be far away from the rotating machine head along the horizontal direction when the wire is pushed, so that the fiber wire can not be contacted with the wire arrangement mechanism when the wire is pushed by the wire pushing rod, and the wire pushing distance is improved.
Further, the push rod is fixed on the supporting plate, and a driving mechanism drives the wire arrangement mechanism and the push rod to integrally move, so that the manufacturing cost is saved.
Further, the driving mechanism is an air cylinder, and a piston shaft of the air cylinder is connected with the supporting plate.
Further, the contact surface of the supporting plate and the sliding groove is provided with balls, rolling friction is formed between the supporting plate and the sliding groove by the balls, and friction force is reduced.
Further, the driving mechanism is an oil cylinder, and a piston rod of the oil cylinder is connected with the supporting plate.
Further, a motor for driving the winding displacement shaft to rotate is arranged on the supporting plate.
