[0002] During the production process of cored wire, a certain amount of waste wire is often generated due to operation and other reasons, especially during the equipment debugging process, the amount of waste wire is relatively large.

[0003] Since the raw materials of cored wire are mainly expensive heavy metal powders, and the outer layer is tightly wrapped with thin iron sheets, the powder of waste wire is difficult to extract. In the industry, the way to deal with waste wires has always been to cut and knock them manually to pour out the powder. This treatment method is inefficient, and the labor cost is much higher than the value of the recovered powder. If the waste wire is directly discarded, it will cause great economic losses and more serious environmental pollution. Waste wire dismantling powder recovery equipment has always been a blank in the entire industry. The development of such equipment has very positive significance in terms of its economic benefits and industry impact. Summary of the invention

DETAILED DESCRIPTION

[0021] The specific implementation of the present invention is further described in detail below with reference to the accompanying drawings:

[0022] Specific implementation method 1: See Figure 1 The cored wire splitting machine for recycling and reusing scrap wires described in this embodiment includes a wire straightening mechanism, a slotting and expanding mechanism, a scrap steel strip outlet mechanism and a receiving hopper. The wire straightening mechanism, the slotting and expanding mechanism and the scrap steel strip outlet mechanism are connected in sequence. A receiving hopper is installed below the slotting and expanding mechanism. The slotting and expanding mechanism includes a slotting guide wheel 7, a slotting milling cutter 9 and a wire expanding cutter 10.

[0023] The cored wire to be recycled enters through the wire straightening mechanism, and after preliminary straightening, enters the slotting guide wheel 7. Under the pressure of the slotting guide wheel 7, the alloy slotting milling cutter 9 cuts regular grooves on the outer steel strip of the cored wire. The cored wire with the grooves cut is expanded and unfolded by the wire expanding knife 10, so that the powder inside the cored wire flows out, and the outflowing powder is collected and recycled by the receiving hopper; the scrap steel strip is discharged by the scrap steel strip discharge mechanism.

[0024] The inlet wire straightening mechanism comprises an inlet wire feeding wheel group and a conductor wheel group 4, and the conductor wheel group 4 is used for preliminary straightening.

[0025] The wire inlet feeding wheel group includes a wire inlet 1 and a wire feeding wheel group, wherein the wire inlet 1 is arranged in front of the wire feeding wheel group for feeding wire, and the wire feeding wheel group is used for guiding.

[0026] The wire feeding wheel group includes an active wire feeding wheel 2 and a driven wire feeding wheel 3. The active wire feeding wheel 2 and the driven wire feeding wheel 3 are arranged opposite to each other, and the driven wire feeding wheel 3 is used for pressing the core-spun wire.

[0027] The slotting and expanding mechanism further comprises a feed wheel set, wherein the feed wheel set comprises a driven feed wheel 5 and an active feed wheel 6, wherein the driven feed wheel 5 and the active feed wheel 6 are arranged opposite to each other, and the driven feed wheel 5 is used for pressing the cored wire.

[0028] The slotting and expanding mechanism further comprises a gas protection box 8, wherein the slotting guide wheel 7, the cutting part of the slotting milling cutter 9 and the front part of the wire expanding cutter 10 are located in the gas protection box 8. The gas protection box 8 is filled with an inert gas.

[0029] The scrap steel strip lead-out mechanism comprises an active steel strip lead-out wheel group and a driven steel strip lead-out wheel with adjustable pressure, and the active steel strip lead-out wheel group is arranged opposite to the driven steel strip lead-out wheel.

[0030] The equipment includes an inlet wire straightening mechanism, a slot expansion mechanism, a scrap steel strip lead-out mechanism and a receiving hopper. The inlet wire straightening mechanism includes an inlet wire feeding wheel group and a conductor wheel group 4; the slot expansion mechanism includes a feed wheel group, a slot guide wheel 7, a slot milling cutter 9 and a wire expansion cutter 10; the scrap steel strip lead-out mechanism includes an active steel strip lead-out wheel group and a driven steel strip lead-out wheel with adjustable pressure.

[0031] The cored wire to be recycled enters from the wire inlet 1, and after preliminary straightening, enters the slotting guide wheel 7 driven by the two-stage wire feeding wheel group. Under the pressure of the slotting guide wheel 7, the alloy slotting milling cutter 9 cuts regular grooves on the outer steel strip of the cored wire. The cutting process is isolated from oxygen under the protection of inert gas to avoid the combustion of flammable metal powder. The cored wire with grooves cut out is expanded by the wire expansion cutter 10, so that the powder inside the cored wire flows out, and the outflowing powder is collected and recycled through the receiving trough; the scrap steel strip is led out by the two-stage steel strip lead-out wheel. The entire wire cutting process is continuous and efficient.

[0032] The cored wire slitting machines in the prior art mostly use a blade to directly cut the cored wire. First of all, the blade is greatly worn out. Long-term operation will cause the blade to no longer be sharp and need to be replaced. Secondly, the direct cutting method has a large resistance to the wire passing. If the wire is fed in too fast, it is easy to get blocked. Therefore, only a low-speed passing method can be used, which is inefficient. Thirdly, the direct cutting method is only suitable for cored wires with thin steel strips, and the applicability is not good. At present, most cored wires use 0.4mm steel strip thickness, but in actual applications, 0.45mm thickness and even 1.0mm thickness cored wires are beginning to increase. In this way, the direct cutting method with a blade is easy to be unable to cut. Moreover, the powder in it needs to be poured out by means of knocking, which is time-consuming and laborious.

[0033] The present invention uses the slotting milling cutter 9 to break the cored wire, and then uses the wire expanding cutter 10 to further expand the cored wire to pour out the powder inside, which is more efficient. In addition, the wheel set structure of the auxiliary wire feeding is more complete and precise.

[0034] The cored wire splitting machine which is beneficial to the recycling and reuse of waste wires

[0035] 1. The cored wire enters from the wire inlet 1, and after preliminary straightening, it enters the wire feeding wheel assembly.

[0036] 2. The wire feeding wheel group sends the wire entering the equipment forward and is guided by the wire guide wheel group 4 into the feed wheel group.

[0037] 3. The broken wire is driven by the feed wheel group to enter the slotting guide wheel 7. Under the pressure of the slotting guide wheel 7, the alloy slotting milling cutter 9 cuts regular grooves on the outer steel belt of the cored wire. Since the alloy powder cored wire usually contains flammable metal magnesium, the slotting mechanism is provided with a gas protection box 8. The gas protection box 8 is continuously and quantitatively filled with protective gas such as carbon dioxide to isolate oxygen and prevent the combustion of metal magnesium.

[0038] 4. The broken cored wire continues to move forward and is expanded by the wire expanding knife 10 to expand the steel strip tube, thereby separating the powder. The separated powder is recovered and bagged through the discharge chute for reuse.

[0039] 5. The unrolled scrap steel strip is led out by the scrap steel strip lead-out wheel group. The scrap steel strip lead-out wheel group has appropriate traction on the led-out scrap steel strip through pressure adjustment of the driven wheel, ensuring that the broken core wire has sufficient forward traction during the breaking process.

[0040] The specific embodiments described above further illustrate the purpose, technical solutions and beneficial effects of the present invention. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the present invention. It can also be a reasonable combination of the features recorded in the above embodiments.
