The vertical cutting knife is a mature prior art, and thus will not be described here.

[0039] Further, the first conveying unit 300 comprises a first traction roller 301, a first transmission roller 302, and a first conveying belt 303 reciprocally running between the first traction roller 301 and the first transmission roller 302, the first traction roller 301 being movable along the width direction of the first conveying belt 303 to drive one end of the first conveying belt 303 to move transversely so as to fine-tune the conveying direction of the first conveying belt 303.

[0040] Further, the first laser curtain unit 400 comprises two first laser curtains, i.e., a first laser curtain a 401 and a first laser curtain b 402, which are arranged in parallel and spaced apart.

[0041] It should be noted that the steel cord on the first transmission roller 302 passes through the first laser curtain a 401 and the first laser curtain b 402 in sequence, and is horizontally adjusted by the transversely moving first conveying belt 303 so as to be 90° to the cutter 500. Specifically, when the steel cord passes through the first laser curtain a 401, the positions of the two lateral edges of the steel cord are obtained to form coordinates A1(X1, 0) and A2(X2, 0), respectively, and when the steel cord passes through the first laser curtain b 402, the positions of the two lateral edges of the steel cord are obtained to form coordinates B1(x1, 0) and B2(x2, 0), respectively.

In this embodiment, the width of the steel cord cut each time is 90 cm, i.e., the steel cord moves forward by 90 cm at a time.

[0042] In the steel cord 90° cutting and rubberizing device of this embodiment, please refer to Figures 1 to 5 , the fitting assembly comprises a 90° reversing device 600, a second conveying unit 900, and a rubber strip front and back fitting unit 110 in sequence, the steel cord receiving position is located at the feeding end of the 90° reversing device 600, and the rubber strip fitting position is located at the rubber strip front and back fitting unit 110.

[0043] It should be noted that the running directions of the first conveying unit 300 and the second conveying unit 900 are perpendicular to each other, the 90° reversing device 600 is located at the joint of the two, and is used to change the conveying direction of the steel cord. The steel cord with the changed conveying direction is conveyed to the rubber strip front and back fitting unit 110 by the second conveying unit 900, and the front and back rubberizing processes are performed thereon, and the steel cord after the processes is wound on the winding roller 160. The 90° reversing device is a mature prior art, which will not be described here.

[0044] In the steel cord 90° cutting and rubber coating device of the embodiment, referring to Figures 1 to 5 , the second laser curtain unit 700 is arranged above the second conveying unit 900, and the cord suture device 800 is arranged between the second laser curtain unit 700 and the rubber strip positive and negative coating unit 110. The cord suture device 800 is a mature prior art, and will not be described here.

[0045] Further, the structure of the second conveying unit 900 is the same as that of the first conveying unit 300, which will not be described here. The second conveying unit 900 adjusts the conveying direction of the second conveying belt through the second traction roller.

[0047] It should be noted that the steel cord cut by the cutter 500 changes from longitudinal movement to transverse movement. During the transverse movement, the steel cord passes through the second laser curtain a 701 and the second laser curtain b 702 in sequence, and is adjusted in the longitudinal direction by the second conveying belt moving longitudinally. Specifically, when the steel cord passes through the second laser curtain a 701, the positions of the two edges of the steel cord along the longitudinal direction form coordinates C1(0, Y1) and C2(0, Y2), respectively. When the steel cord passes through the second laser curtain b 702, the positions of the two edges of the steel cord along the longitudinal direction form coordinates D1(0, y1) and D2(0, y2), respectively. The second traction roller is moved so that C1(0, Y1)=D1(0, y1) and C2(0, Y2)=D2(0, y2), and Y2-Y1=y2-y1=90 cm. The steel cord after the adjustment is conveyed to the cord suture device 800, and the two steel cords are sutured by high-temperature heating.

[0048] In the steel cord 90° cutting and rubber coating device of the embodiment, referring to Figures 1 to 6 , the rubber strip positive and negative coating unit 110 includes a front coating roller 1101 and a back coating roller 1102. A reversing guide wheel set for guiding the small rubber strips after cutting is arranged between the front coating roller 1101 and the multi-cutter longitudinal cutting unit 140 and between the back coating roller 1102 and the multi-cutter longitudinal cutting unit 140. A first guide roller 1103 for reversely conveying the steel cord after the front rubber strip coating is arranged between the front coating roller 1101 and the back coating roller 1102.

[0049] Further, for the rubber strip slitting assembly, the rubber strip extrusion unit 120 adopts an extruder, the rubber strip cooling unit 130 adopts a cooling roller air conditioner room, and the multi-blade longitudinal cutting unit 140 includes a longitudinal cutting knife 1401 and a cutting roller 1402 rotatable in cooperation with the longitudinal cutting knife 1401. The number of the longitudinal cutting knife 1401 can be adjusted according to the number of the small rubber strips 150 after slitting. The small rubber strips 150 after cutting are guided to different unwinding guide wheels 1403, respectively, and then transported to the front surface laminating roller 1101 and the back surface laminating roller 1102 through the reversing guide wheel set. Specifically, taking the front surface laminating roller 1101 as an example, the small rubber strips 150 after cutting are transported to the front surface laminating roller 1101 through the unwinding guide wheel 1403, the first reversing wheel 1106, the second reversing wheel 1107 and the guide wheel 1104 in sequence, wherein the first reversing wheel 1106, the second reversing wheel 1107 and the guide wheel 1104 form a reversing guide wheel set, the first reversing wheel 1106 reverses the small rubber strips 150 after cutting once, and the second reversing wheel 1107 reverses the small rubber strips 150 after cutting twice.

[0050] Further, the front surface and the back surface of the steel cord are laminated with rubber strips, which is a mature prior art. Taking the front surface laminating roller 1101 as an example, the structure of the front surface laminating roller 1101 can adopt the structure of the laminating mechanism in CN202111586623.8.

[0051] It should be noted that after the steel cord is sewn, it is returned through the conveying line, the front surface is laminated with small rubber strips, and it is assumed that the first small rubber strip needs to be 5CM away from the longitudinal edge, so the coordinates are G(0, y1+5). The lamination positions of other small rubber strips are determined in sequence. After the front surface rubber strip lamination of the steel cord is completed, the steel cord is returned downward through the first guide roller 1103, and the back surface rubber strip lamination is performed. The lamination method is the same as the front lamination. After the back surface rubber strip lamination is completed, the steel cord is continuously returned downward through a plurality of second guide rollers 1105 to the lowermost layer, and finally wound on the winding roller 160.

[0052] The above has made a detailed description of the present application. The above is only a preferred embodiment of the present application, which cannot limit the scope of the present application. Any equivalent changes and modifications made within the scope of the present application shall still fall within the scope of the present application.
