DETAILED DESCRIPTION

[0027] The specific implementation of the utility model is described in detail below with reference to the accompanying drawings:

[0028] like Figure 2~Figure 6 As shown, an outer winding machine wire passing device is used for positioning and defect monitoring of the steel cord 3 between the guide wheel 1 and the guide wheel 2. When the steel cord 3 passes through the guide wheel 1 and the guide wheel 2, the outer winding machine wire passing device can position the steel cord 3 to prevent it from shaking, and also detect its defects to avoid the occurrence of unqualified products such as wire skipping.

[0029] The outer winding machine wire passing device includes a mounting bracket 4, a detection component 5 and a positioning component 6. Figure 3 and Figure 4 The mounting bracket 4 is movably arranged on the outer winding machine between the guide wheel 1 and the guide wheel 2, and the mounting position and angle of the mounting bracket 4 can be adjusted to well adapt to the passing path of the steel cord 3.

[0030] In this embodiment, the mounting bracket 4 includes a bracket 1 7 and a bracket 2 8 that are detachably connected front and back. The bracket 1 7 and the bracket 2 8 are two independent parts. The bracket 1 7 and the bracket 2 8 are connected and combined to form the mounting bracket 4. The bracket 1 7 includes a bottom plate 71 and a connecting plate 1 72. The connecting plate 1 72 is arranged on the front side of the bottom plate 71. The bottom plate 71 and the connecting plate 1 72 are arranged vertically. The cross section of the bottom plate 71 and the connecting plate 1 72 after being connected and combined is in the shape of a "𠃍".

[0031] Bracket 17 is used to connect and fix with the outer winding machine. When bracket 17 is installed with the outer winding machine, an adjustment hole 9 is opened on the bottom plate 71. The number of the adjustment holes 9 is two arranged up and down. The adjustment holes 9 are long holes. An adjustment bolt 10 is inserted into each adjustment hole 9. Bracket 17 is connected and fixed with the outer winding machine through the adjustment bolt 10. After loosening the adjustment bolt 10, bracket 17 can be moved left and right to adjust the position. Tightening the adjustment bolt 10 can fix bracket 17.

[0032] The bracket 2 8 includes a top plate 81 and a connecting plate 2 82. The connecting plate 2 82 is arranged at the rear side of the top plate 81. The top plate 81 and the connecting plate 2 82 are arranged vertically. The cross section of the top plate 81 and the connecting plate 2 82 is "T" shaped after being connected and combined. When the bracket 2 8 and the bracket 1 7 are installed, the connecting plate 2 82 and the connecting plate 1 72 are overlapped and arranged, and are provided with mounting bolts 11, thereby the bracket 1 7 and the bracket 2 8 can be connected and fixed. On the basis of fixing the bracket 1 7, the pitch angle of the bracket 2 8 can be adjusted after loosening the mounting bolts 11.

[0033] A detection assembly 5 for monitoring surface defects of the steel cord 3 is arranged on the mounting bracket 4, and a positioning assembly 6 is also arranged on the mounting bracket 4. The positioning assemblies 6 are arranged above and below the detection assembly 5, that is, there are two positioning assemblies 6 and only one detection assembly 5. Here, the detection assembly 5 and the positioning assembly 6 are arranged on the front side of the top plate 81 of the mounting bracket 4.

[0034] The detection component 5 is a magnetic flux sensor, and a detection hole 51 is provided on the detection component 5, and the steel cord 3 passes through the detection hole 51. When the steel cord 3 passes through the detection hole 51, the detection component 5 detects the magnetic flux of the steel cord 3 in real time. If there are defects such as incompleteness and wire skipping on the surface of the steel cord 3, the magnetic flux will be less than the set value in the magnetic flux sensor, and then an alarm is issued.

[0035] The positioning assembly 6 is used to prevent the steel cord 3 from shaking and jumping during operation. The positioning assembly 6 includes a mounting plate 12 and a slotted guide wheel 13. Figure 5 and Figure 6 The mounting plate 12 is a steel disc structure, and the mounting plate 12 is detachably mounted on the mounting bracket 4. Specifically, the mounting plate 12 and the mounting bracket 4 are provided with fixing bolts 14, and the fixing bolts 14 are located at the center of the mounting plate 12. The fixing bolts 14 axially pass through the center of the mounting plate 12 and are threadedly connected and fixed with the mounting bracket 4, so that the mounting plate 12 can be fixed on the top plate 81.

[0036] Two slotted guide wheels 13 are rotatably arranged on the mounting plate 12. The slotted guide wheels 13 can rotate relative to the mounting plate 12, and the line between the two slotted guide wheels 13 passes through the center of the mounting plate 12. When the slotted guide wheels 13 are installed, a plurality of threaded holes 15 are circumferentially arranged on the mounting plate 12, and any two connecting lines are connected to the slotted guide wheels 13 by bolts through the threaded holes 15 at the center of the mounting plate 12, that is, the slotted guide wheels 13 are installed by bolt connection.

[0037] The slotted guide wheel 13 includes an annular wheel body 132 with a bearing 131 on the inner ring and a V-shaped groove 133 formed on the circumference of the wheel body 132. A screw 16 is inserted into the bearing 131, and the screw 16 is connected and fixed to the threaded hole 15, which not only realizes the installation of the slotted guide wheel 13, but also does not affect the rotation of the slotted guide wheel 13. A sleeve 17 is also sleeved on the screw 16 between the mounting plate 12 and the bearing 131 to limit the position of the slotted guide wheel 13.

[0038] After the utility model is installed on the outer winding machine, the steel cord 3 located between the guide wheel 1 and the guide wheel 2 is wound between the positioning assembly 6 located above, the detection assembly 5 and the positioning assembly 6 located below, and the steel cord 3 is wound between the two slotted guide wheels 13 of each positioning assembly 6, such as Figure 2 shown.

[0039] The principle of the utility model is as follows: the positioning assembly 6 needs to be adjusted first, the fixing bolts 14 are loosened, the mounting plate 12 is in a rotatable state, the mounting plate 12 is manually rotated, and the two slotted guide wheels 13 on the mounting plate 12 are offset together, until the two slotted guide wheels 13 cooperate to clamp the steel cord 3, and the slotted guide wheels 13 exert a certain pressure on the steel cord 3. At this time, the fixing bolts 14 are tightened to ensure the fixation of the position of the slotted guide wheels 13, thereby realizing the positioning of the steel cord 3 and preventing running jitter.

[0040] The adjustment methods of the upper and lower positioning components 6 are the same. The two positioning components 6 are used to stabilize the tension fluctuation of the steel cord 3, effectively preventing the jumping and shaking problems of the steel cord 3 during operation. At the same time, during the operation of the steel cord 3, the detection component 5 is used to monitor the defective steel cord 3 in real time through the change of the magnetic flux signal, so as to realize instant alarm, avoid the continuous generation of defective products, and effectively ensure product quality.

[0041] The embodiments described above are only preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. Therefore, any equivalent changes or modifications made based on the structures, features and principles described in the patent scope of the present invention should be included in the patent application scope of the present invention.
