[0038] The transverse slot widening mechanism 30 comprises symmetrically arranged transverse slot small rollers 31, transverse slot elastic widening conveyor belts 32, transverse slot large rollers 33, widening conveyor belt pullers 34, and fixed supports 35. The transverse slot small rollers 31 are symmetrically arranged and installed at the front end of the transverse slot widening mechanism 30. A transverse slot structure is arranged on the outer surface of the transverse slot small rollers 31. The transverse slot small rollers 31 are located at the starting position of the fiber bundle 100 widening process. The fiber bundle 100 is widened starting from the right end of the symmetrically arranged transverse slot small rollers 31. The transverse slot large rollers 33 are symmetrically arranged and installed at the rear end of the transverse slot widening mechanism 30. A transverse slot structure is arranged on the outer surface of the transverse slot large rollers 33. The transverse slot large rollers 33 are located at the ending position of the fiber bundle 100 widening process. The fiber bundle 100 is shaped after the final widening of the symmetrically arranged transverse slot large rollers 33. The transverse slot elastic widening conveyor belts 32 are arranged around the outer sides of the transverse slot small rollers 31 and the transverse slot large rollers 33. The inner surfaces of the transverse slot elastic widening conveyor belts 32 in contact with the transverse slot small rollers 31 and the transverse slot large rollers 33 are arranged with uniformly distributed transverse slots compatible with the transverse slot structures of the transverse slot small rollers 31 and the transverse slot large rollers 33. The transverse slot elastic widening conveyor belts 32 and the transverse slot large / small rollers cooperate with each other to convey and extrude the fiber bundle 100 in face-to-face contact, thereby keeping the fiber bundle 100 fully widened in the transverse slot widening mechanism 30. The upper ends of the fixed supports 35 are arranged and installed at the two ends of the transverse slot small rollers 31 and the transverse slot large rollers 33. The lower ends of the fixed supports 35 are fixedly installed with the base plate 90, thereby fixing the symmetrically arranged transverse slot small rollers 31 and the transverse slot large rollers 33. The widening conveyor belt pullers 34 are arranged and fixed at the rear end of the transverse slot widening mechanism 30. The upper ends of the widening conveyor belt pullers 34 are arranged as two groups of symmetrically rotating spherical bodies. The rotating spherical bodies clamp and act on the transverse slot elastic widening conveyor belts 32, thereby pulling and adjusting the width of the output end of the transverse slot elastic widening conveyor belts 32. The outer sides of the elastic widening conveyor belts 32 are arranged with outer widening columns embedded in the widening conveyor belt pullers. When moving from front to back, the elastic widening conveyor belts 32 are expanded and widened outward under the action of the widening conveyor belt pullers 34.

[0039] Further, the two ends of the transverse slot small rollers 31 are arranged with width limiting structures, thereby preventing the transverse slot elastic widening conveyor belts 32 passing through one end of the transverse slot small rollers 31 from being thinned.

[0040] Further, the transverse slot small rollers 31 and the transverse slot large rollers 33 are arranged to be non-equal in length. Preferably, the length of the transverse slot small rollers 31 is about 1 / 2 of the length of the transverse slot large rollers 33. The transverse slot elastic widening conveyor belts 32 around the outer surfaces of the transverse slot small rollers 31 and the transverse slot large rollers 33 also form a non-equal width state at the two ends, thereby cooperating with the gradual widening process of the fiber bundle 100.

The servo motor 51 drives the lead screw 53 to rotate in the forward or reverse direction. Under the threaded rotation, the lead screw 53 moves axially to adjust the relative position of the threaded adjustment seat II 54 mounted on the pad 90, thereby driving the pad 90 to move on the base plate 80 to adjust the distance between the threaded adjustment seats I 52 and II 54. Furthermore, the tension of the transverse groove elastic widening conveyor belt 32 wrapped around the large and small rollers is adjusted. Furthermore, under the action of tension, the thickness and length of the transverse groove elastic widening conveyor belt 32 are adjusted.

[0045] Furthermore, the tension device I includes a tension roller 21 and a fixing plate 22. The number of tension rollers is 3, and the tension rollers 21 are installed in an inverted "V" shape. The fixing plate 22 is fixed at both ends of the 3 tension rollers 21 to fix the 3 tension rollers 21. The fiber bundle 100 enters from the right end, wraps around the outer surface of the first tension roller 21, wraps downward around the surface of the second tension roller 21, and then wraps upward around the outer surface of the third tension roller 21 before exiting from the left end and entering the stretching mechanism 30, which serves to maintain the tension of the fiber bundle 100 before stretching.

[0046] Furthermore, the tension device II 60 includes a tension roller 61 and a fixing plate 62. Similarly, the tension device II 60 is configured the same as the tension device I 20. After the fiber bundle 100 comes out from the right end widening mechanism, it enters and wraps around the outer surface of the first tension roller 61, then downwards around the outer surface of the second tension roller 61, and then upwards around the outer surface of the third tension roller 61 before exiting from the left end, thus maintaining the tension of the widened fiber bundle 100.

[0047] The implementation process of the utility model discloses: narrow fiber bundle is introduced to tension device I 20 from left end, is introduced to transverse slot elastic spreading conveyor belt 32 after passing through tension device I 20, and the width of the left end of transverse slot elastic spreading conveyor belt 32 is widened under the action of spreading conveyor belt tractor 34, and simultaneously, fiber bundle 100 is in the face-to-face contact extrusion of the common symmetrical setting transverse slot small pulley 31, transverse slot elastic spreading conveyor belt 32 and transverse slot large pulley 33 on spreading mechanism 30, and the width of narrow fiber bundle 100 is widened and widened in the process of being transported from transverse slot small pulley 31 to transverse slot large pulley 33 along with the width of transverse slot elastic spreading conveyor belt 32 gradually widening, and the spreading is completed at transverse slot large pulley 33, and fiber bundle 10 is output after completing spreading through tension device II 60.

At the end of the unfolding process, the fiber bundle 100 is finally widened and shaped after passing through the symmetrically arranged elastic longitudinal groove large rollers 73. The longitudinal groove elastic widening conveyor belt 72 is arranged around the outer surface of the longitudinal groove small rollers 71 and the longitudinal groove large rollers 73. The inner surface of the longitudinal groove elastic widening conveyor belt 72 in contact with the longitudinal groove small rollers 71 and the longitudinal groove large rollers 73 is provided with circumferential grooves that are evenly distributed and adapted to the circumferential groove shape of the longitudinal groove large / small rollers.
