[0025] See also Figure 1-Figure 5 The utility model discloses a steel wire cutting device for recycling scrap tires, comprising a lower machine base 1, a horizontal conveyor belt 3 and a cutting mechanism. The cutting mechanism comprises a cutting bracket 15 arranged on the upper side of one end of a limiting vertical plate 7. A lifting plate 17 is provided on the top of the cutting bracket 15 through a third hydraulic cylinder 16, and a punching blade 18 is provided in the middle of the lower side of the lifting plate 17. The punching blade 18 is driven downward by the third hydraulic cylinder 16 to cut the scrap steel wire bundle transmitted on the horizontal conveyor belt 3.

[0026] In order to improve the accuracy of the lifting and lowering of the punching blade 18, a limiting slide groove 19 is also provided on the inner wall of the cutting bracket 15, and the two ends of the lifting plate 17 are slidably arranged with the limiting slide groove 19 through a limiting slider 20, which is used to perform sliding guiding processing when the lifting plate 17 and the punching blade 18 are lifted and lowered.

[0027] like Figure 1 、 Figure 2 and Figure 4 As shown, in order to perform transverse clamping processing on the steel wire waste, a steel wire transverse extrusion mechanism is also provided, which includes a limiting vertical plate 7 arranged on the upper side of the lower machine base 1, and a side limiting clamping plate 8 is provided on one side of the limiting vertical plate 7 through a first hydraulic cylinder 9, and the side limiting clamping plate 8 is arranged perpendicular to the horizontal conveyor belt 3 inside the lower machine base 1, and is used for transverse clamping and limiting conveying processing of the steel wire waste transported on the upper part of the horizontal conveyor belt 3.

[0028] In this embodiment, in order to improve the stability of the movement and extrusion of the side limit splint 8, a first guide rod 10 is provided on one side of the side limit splint 8 for sliding with the limit vertical plate 7, and a limit end plate 11 is provided at one end of the two first guide rods 10 for slidingly guiding the side limit splint 8 when it moves horizontally.

[0029] like Figure 1 、 Figure 2 and Figure 3 As shown, in order to perform vertical extrusion processing on the scrap steel wire bundles after horizontal extrusion, a longitudinal steel wire extrusion mechanism is further provided. The longitudinal steel wire extrusion mechanism includes an upper frame 12 located on the upper part of the limiting vertical plate 7. A longitudinal extrusion plate 14 is provided on the top of the upper frame 12 through a second hydraulic cylinder 13. The longitudinal extrusion plate 14 is driven downward by the second hydraulic cylinder 13 to perform vertical extrusion processing on the scrap steel wire bundles after horizontal extrusion, and can extrude larger scrap steel wire bundles into smaller rectangular strips, which is convenient for subsequent cutting processing by a cutting mechanism.

[0030] In this embodiment, in order to meet the longitudinal extrusion processing of steel wire bundles of different widths, a movable upper pressure plate 22 is provided on both sides of the longitudinal extrusion plate 14 through an elastic telescopic structure. The elastic telescopic structure includes a support rod 21 arranged on one side of the movable upper pressure plate 22. One end of the support rod 21 is slidably arranged with the telescopic cavity 26 inside the longitudinal extrusion plate 14 through a guide slider 25, and the support rod 21, the guide slider 25 and the longitudinal extrusion plate 14 are symmetrically arranged. A compression spring 27 is provided between the two guide sliders 25. The support rod 21 and the movable upper pressure plate 22 are also used for longitudinal extrusion processing of the steel wire bundle. The elastic telescopic structure is used to adapt to longitudinal extrusion of different widths, and can adjust the distance between the two movable upper pressure plates 22 according to the distance between the two side limit splints 8, thereby meeting the longitudinal extrusion waste steel wire processing of different widths.

[0031] like Figure 1 and Figure 2 As shown, in order to realize horizontal transmission of scrap steel wire bundles for continuous cutting, both ends of the horizontal conveyor belt 3 are rotationally connected to the lower machine base 1 through a transmission wheel 4 and a transmission shaft. One end of the transmission shaft is connected to an electric motor 6 through a gear set 5. The horizontal conveyor belt 3 is a metal chain conveyor belt, which is used for horizontal transmission of scrap steel wire bundles for continuous cutting, so that the cutting efficiency is higher.

[0032] In this embodiment, in order to allow the scrap steel wire bundle to be horizontally conveyed on the upper part of the horizontal conveyor belt 3, an anti-slip rib 2 is also provided on the outer side of the middle part of the horizontal conveyor belt 3, which increases the anti-slip property of the upper side of the horizontal conveyor belt 3 and facilitates the horizontal movement of the scrap steel wire bundle as the horizontal conveyor belt 3 rotates.

[0033] Furthermore, in order to achieve longitudinal extrusion of the steel wire bundle while also horizontally conveying the steel wire bundle, an upper chain plate conveyor belt may be provided outside the longitudinal extrusion plate 14 to improve the smoothness of horizontal conveyance of the steel wire bundle between the longitudinal extrusion plate 14 and the horizontal conveyor belt 3.

[0035] The working principle and use process of the utility model are as follows: when in use, the tire waste steel wire to be cut is placed on the feeding end of the horizontal conveyor belt 3 of the lower machine base 1, and the tire waste steel wire is transported to the two side limit clamps 8 of the steel wire transverse extrusion mechanism through the horizontal conveyor belt 3, and then the side limit clamps 8 are driven by the first hydraulic cylinder 9 to move to the side close to the tire waste steel wire, and the steel wire waste transported on the upper part of the horizontal conveyor belt 3 is transversely clamped, and then the longitudinal extrusion plate 14 is driven downward by the second hydraulic cylinder 13 of the steel wire longitudinal extrusion mechanism to extrude the tire waste steel wire in the transverse direction. The scrap steel wire bundle is pressed upward. After the pressing is completed, the second hydraulic cylinder 13 drives the longitudinal extrusion plate 14 to move upward, and then the horizontal conveyor belt 3 drives the extruded scrap steel wire bundle to move below the punching blade 18 of the cutting mechanism. Then, the second hydraulic cylinder 13 drives the longitudinal extrusion plate 14 to move downward to press and position the scrap steel wire bundle to be cut. Then, the third hydraulic cylinder 16 drives the lifting plate 17 and the punching blade 18 to move downward to cut the steel wire bundle. The cut steel wire bundle is discharged from the other end of the horizontal conveyor belt 3, completing the cutting and use of the scrap steel wire bundle.
