Description

Technical Field

[0001] This utility model relates to the field of cored wire splitting technology, and more specifically, to a cored wire splitting device for recycling and reusing waste wires. Background Technology

[0002] Cored wire is made by wrapping alloy powder around strip steel. During the production, transportation, and storage of cored wire, improper production operations, external damage, or unsuitable storage environments can all lead to damage, resulting in waste cored wire. Furthermore, when cored wire is used in steelmaking, due to limitations in steelmaking technology, the last section of a roll of cored wire often cannot be used and becomes waste. Additionally, during the production process, instability in production equipment or deviations in adjustment can cause problems such as insufficient material, empty space, indentations, or scratches, rendering these defective cored wires unusable for steelmaking and thus waste. However, waste cored wire still has some economic value; therefore, it is usually recycled.

[0003] The most common method for recycling cored wire is to first cut the cored wire into sections, and then manually knock off the alloy powder. Since the outer sheath of the waste cored wire is a tough steel strip, another common method is to use an alloy grooving milling cutter to cut the outer sheath of the waste cored wire. However, both of these methods are inefficient, time-consuming and labor-intensive, and they do not completely remove the metal powder contained in the cored wire, resulting in material waste. Utility Model Content

[0004] The purpose of this invention is to solve the problems mentioned in the background art, and to propose a cored wire splitting device for waste wire recycling and reuse, which facilitates the recycling and reuse of waste cored wire, saves time and effort, and improves work efficiency.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A cored wire splitting device for waste wire recycling includes a speed change system and a guide roller assembly, a splitting roller assembly, a wire expanding roller assembly, and a cutting roller assembly, which are sequentially mounted on a unit mounting plate. The guide roller assembly, splitting roller assembly, wire expanding roller assembly, and cutting roller assembly are composed of upper and lower rollers that are respectively mounted on upper and lower drive shafts and can rotate flexibly. The upper roller of the wire expanding roller assembly has a concave groove with a semi-circular cross-section on its circumferential direction. A wire expanding knife connecting plate is installed on the lower roller of the wire expanding roller assembly at the center position of the semi-circular groove on its circumferential direction. A wire expanding knife is installed at the other end of the wire expanding knife connecting plate. A cutting blade is installed on the outer surface of the upper roller of the cutting roller assembly perpendicular to the circumferential direction. A concave groove with a semi-circular cross-section is opened on the outer surface of the lower roller of the cutting roller assembly at the position of the rectangular cutting blade on its circumferential direction.

[0007] Furthermore, at the center of the outer surface of the upper and lower rolls of the guide roll assembly, there is a concave groove with a semi-circular cross-section along the circumferential direction. At the center of the circumferential direction of the upper roll surface of the slitting roll assembly, there is a concave groove with a semi-circular cross-section. At the center of the circumferential direction of the lower roll surface of the slitting roll assembly, there is an annular slitting blade installed.

[0008] Furthermore, the upper rolls of the guide roll group, the upper rolls of the slitting roll group, the upper rolls of the expanding roll group, and the upper rolls of the cutting roll group are each connected to the speed transmission system via their respective upper drive shafts; the lower rolls of the guide roll group, the lower rolls of the slitting roll group, the lower rolls of the expanding roll group, and the lower rolls of the cutting roll group are each connected to the speed transmission system via their respective lower drive shafts.

[0009] Furthermore, a powder collection box is installed below both the cutting roller group and the expanding roller group.

[0010] Furthermore, a collection box is installed below the cutting roller assembly.

[0011] Furthermore, the cutting blade is a rectangular blade.

[0012] Furthermore, the groove on the outer surface of the lower roller of the cutting roller group has a length perpendicular to the circumferential direction that is twice the length of the rectangular blade, and a depth equal to the width of the cutting blade, which facilitates the cutting blade to cut waste cored wire.

[0013] Furthermore, the outer periphery of the slitting blade is serrated.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This utility model adopts a fully automated waste cored wire recycling system. The process of wire splitting, powder collection, and cutting can be easily completed in one set, which has high work efficiency and reduces the input of manual labor. During the operation, the cutting blade cuts the waste cored wire, and the spreading roller group spreads out the cut waste cored wire. The core powder in the waste cored wire falls into the powder collection box. The cutting blade cuts the waste cored wire that no longer has core powder. The cut waste cored wire segments are collected by the collection box. The core powder and waste cored wire segments are recycled and reused. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments:

[0025] See attached document Figure 1 , Figure 2 As shown, a cored wire splitting device for waste wire recycling includes a speed change system 1 and, from right to left, a conductor tube 4, a guide roller group, a splitting roller group, a wire expanding roller group, and a cutting roller group, all mounted on a unit mounting plate 24. The conductor tube 4 is mounted on the far right of the unit mounting plate 24 via a conductor tube bracket 15. The guide roller group is directly mounted on the unit mounting plate 24 via a guide roller group 16, adjacent to the left side of the conductor tube 4. The splitting roller group is mounted on the unit mounting plate 24 via a splitting roller group bracket 17, adjacent to the guide roller group. The wire expanding roller group is mounted on the unit mounting plate 24 via a wire expanding roller group bracket 18, adjacent to the splitting roller group. The cutting roller group is mounted on the unit mounting plate 24 via a cutting roller group bracket 19.

[0026] The guide roller group, slitting roller group, expanding roller group, and cutting roller group are composed of upper and lower rollers that are respectively mounted on upper and lower drive shafts and can rotate flexibly. The upper roller 5 of the guide roller group, the upper roller 6 of the slitting roller group, the upper roller 7 of the expanding roller group, and the upper roller 8 of the cutting roller group are respectively connected to the speed change system through their respective upper drive shafts 2; the lower roller 11 of the guide roller group, the lower roller 12 of the slitting roller group, the lower roller 13 of the expanding roller group, and the lower roller 14 of the cutting roller group are respectively connected to the speed change system through their respective lower drive shafts 2; for example Figure 3 As shown, at the center of the outer surface of the upper roll 5 and the lower roll 11 of the guide roll assembly, a concave groove with a semi-circular cross-section is formed along the circumferential direction. Figure 4 As shown, at the center of the outer surface of the upper roll 6 of the slitting roll assembly, there is a concave groove with a semi-circular cross-section along the circumferential direction. A ring-shaped slitting blade 20 is installed on the outer surface of the lower roll 12 of the slitting roll assembly, directly opposite the center of the semi-circular groove. Figure 7 As shown in the diagram, a circular sectioning blade is used. Figure 7 As shown, the outer periphery of the annular slitting blade is serrated.

[0027] like Figure 6 As shown, a cutting blade 23 is installed at the center of the outer surface of the upper roller 8 of the cutting roller group, perpendicular to the circumference. The cutting blade 23 is a rectangular blade. A groove with a semi-circular cross-section is opened on the outer surface of the lower roller 14 of the cutting roller group, directly opposite the rectangular blade 23. The length of the groove on the outer surface of the lower roller 14 of the cutting roller group perpendicular to the circumference is twice the length of the rectangular blade 23, and the depth is equal to the width of the cutting blade, which facilitates the cutting blade to cut the waste cored wire 3.

[0028] like Figure 5 As shown, a concave groove with a semi-circular cross-section is opened in the circumferential direction at the center of the outer surface of the upper roller 7 of the expanding roller group. An annular expanding knife connecting plate 21 is installed in the circumferential direction of the lower roller 13 of the expanding roller group, directly opposite the center of the semi-circular groove. An annular expanding knife 22 is installed on the annular expanding knife connecting plate. The expanding connecting plate 21 and the expanding knife can pass through the core wire 3 along the cut of the core wire and spread the core wire out.

[0029] A powder collection box 10 is installed below both the cutting roller group and the expanding roller group to facilitate the collection of falling core powder, and a collection box 9 is installed below the cutting roller group.

[0030] When recycling waste cored wire 3 using this invention, the transmission system is first started, driving the guide roller group, slitting roller group, wire expanding roller group, and cutting roller group to start operating via the drive shaft. Then, the waste cored wire is fed into the guide roller group through the wire guide tube. The guide roller group then feeds the cored wire into the slitting roller group. The slitting blade installed on the lower roller 12 of the slitting roller group cuts the waste cored wire 3. During the cutting process, a small amount of core powder will slip off and fall into the powder collection box 10 installed below the slitting roller group. The slitting roller group then removes the cut wire. The waste cored wire is fed into the expansion roller assembly. The expansion connecting plate and expansion knife installed on the lower roller 13 of the expansion roller assembly unfold the cut waste cored wire 3. All the core powder inside the cored wire 3 falls into the powder collection box 10 installed below the expansion roller assembly. Finally, the waste cored wire shell, which no longer has core powder, is fed into the cutting roller assembly. The cutting blade installed on the upper roller 8 of the cutting roller assembly cuts the waste cored wire shell into sections that fall into the collection box 9. The core powder and the waste cored wire shell can be recycled and reused.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
