Description

Technical field:

[0001] The utility model relates to the technical field of wire stripping, in particular to a wire stripping conveying and lifting wheel mechanism. Background technology:

[0002] At present, in the production process of industries that need to use wires, cables and other wires, it is often necessary to peel off the wire skin at the end of the wires, cables and other wires to fully expose the internal guide wires for wiring and other work. The commonly used method now is to use two sets of front and rear conveyor wheels to convey the wires, and a cutter is provided between the two sets of conveyor wheels. The two sets of conveyor wheels first drive the wires to be conveyed backwards. When the front end of the wire exceeds the cutter for a certain distance, the cutter is controlled to cut off the wire skin. The two sets of conveyor wheels then drive the wires to be conveyed forward, and the front end of the wire will be pulled out from the rear conveyor wheel, so that the wire skin at the front end of the wire is peeled off and the guide wire is completely exposed. Then the front conveyor wheel drives the wire to continue to be conveyed backwards. At this time, when the guide wire exposed at the front end of the wire re-enters between the two rear conveyor wheels, due to the small distance between the two rear conveyor wheels, the front end guide wire of the wire can easily collide with the two rear conveyor wheels, bending the front end guide wire of the wire or even causing damage, resulting in a high scrap rate and affecting the quality of wire stripping.

[0003] In summary, the collision problem between the wire guide and the two rear conveying wheels after the front end of the wire is stripped has become a technical problem that urgently needs to be solved in the industry. Utility model content:

The electric wheel lifting mechanism 13 and the knob wheel lifting mechanism 14 can be arbitrarily selected according to needs, and the electric wheel lifting mechanism 13 and the knob wheel lifting mechanism 14 are respectively used to adjust the height of the rear upper conveying wheel 6.

[0024] The electric wheel lifting mechanism 13 includes a wheel lifting motor 15 installed on the frame 1, a rotating block 16 is fixedly installed on the output shaft of the wheel lifting motor 15, an electric wheel lifting bearing 17 is installed on the rotating block 16, an inverted L-shaped plate 18 is fixed on the rear gear box 8, a pushing screw 19 is provided on the horizontal plate of the inverted L-shaped plate 18, and the pushing screw 19 cooperates with the electric wheel lifting bearing 17. When the wheel lifting motor 15 is working, the output shaft of the wheel lifting motor 15 drives the rotating block 16 to rotate, and the rotating block 16 drives the electric wheel lifting bearing 17 to rotate. When the electric wheel lifting bearing 17 rotates to the position of the pushing screw 19, the electric wheel lifting bearing 17 pushes the screw 19 upward, and the pushing screw 19 drives the rotating side of the rear gear box 8 to rotate upward through the inverted L-shaped plate 18, and the output shaft of the rear gear box 8 will move upward in the long hole 9, thereby driving the rear upper conveying wheel 6 to move upward, so as to increase the spacing between the rear lower conveying wheel 5 and the rear upper conveying wheel 6, so as to facilitate the front end guide wire of the electric wire to smoothly enter between the rear lower conveying wheel 5 and the rear upper conveying wheel 6.

[0030] When the wire sheath at the front end of the wire is peeled off, the wire guide at the front end is completely exposed, and then the front conveying wheel mechanism 2 drives the wire to continue to be conveyed backward. When the wire guide at the front end re-enters between the rear lower conveying wheel 5 and the rear upper conveying wheel 6, the electric wheel lifting mechanism 13 or the knob wheel lifting mechanism 14 is operated to lift the rear upper conveying wheel 6 upward to increase the spacing between the rear lower conveying wheel 5 and the rear upper conveying wheel 6, so that the wire guide at the front end smoothly enters between the rear lower conveying wheel 5 and the rear upper conveying wheel 6. After the wire guide at the front end enters, the electric wheel lifting mechanism 13 or the knob wheel lifting mechanism 14 is operated to drop the rear upper conveying wheel 6, thereby avoiding the wire guide at the front end from colliding with the rear lower conveying wheel 5 and the rear upper conveying wheel 6, avoiding the wire guide at the front end from bending and causing damage, and protecting the wire guide at the front end.
