DETAILED DESCRIPTION

[0034] The present application will be further described in detail below in combination with the drawings.

[0035] In combination with the drawings Figure 1 A fiber belt deviation corrector, comprising an upper cover 1, a bottom shell 2 and a fiber belt 3, the upper cover 1 is detachably arranged on the bottom shell 2, the bottom shell 2 is hollow inside, the upper cover 1 and the bottom shell 2 form through holes on both sides after being detachably arranged, the fiber belt 3 passes through the upper cover 1 and the bottom shell 2 for conveying through the through holes on both sides, and the bottom shell 2 is provided with a sensor for detecting the deviation of the silk belt and a deviation correction mechanism.

[0036] In combination with the drawings Figure 1 , the drawings Figure 2 and the drawings Figure 3The bottom shell 2 has a horizontal camshaft 7 in the middle. The camshaft 7 can rotate and slide axially. The rotation axis of the camshaft 7 is perpendicular to the conveying direction of the fiber belt 3. A cam 16 is provided on the outside of the camshaft 7. When the fiber belt 3 is conveyed normally, it is located above the camshaft 7 and the cam 16. The rotation of the camshaft 7 can drive the cam 16 to contact the bottom surface of the fiber belt 3. The axial sliding of the camshaft 7 drives the fiber belt 3 to move and correct its deviation through the friction between the cam 16 and the bottom surface of the fiber belt 3.

[0037] This device also requires a microcontroller to receive signals from the sensors and control the operation of the correction mechanism. Such devices are common existing technologies and will not be described further in this application.

[0038] Combined with appendix Figure 6 Appendix Figure 9 Appendix Figure 10 and attached Figure 11 The camshaft 7 is provided with a guide wheel 17 at one end. A guide groove 18 is provided around the outer side of the guide wheel 17. The guide groove 18 is provided with bends 19 on the opposite side of the cam 16 and near the cam 16. After the guide groove 18 is bent by the bends 19, its trajectory has a certain offset along the rotation axis of the camshaft 7. The bottom shell 2 is provided with a bearing column 20. A pulley 21 is rotatably provided on the top of the bearing column 20. The pulley 21 extends into the guide groove 18, and the circumferential surface of the pulley 21 is in contact with the side wall of the guide groove 18.

[0039] When the camshaft 7 rotates, the guide wheel 17 rotates synchronously with the camshaft 7. During this process, the bearing column 20 remains stationary, and the pulley 21 rolls continuously in the guide groove 18. When the guide wheel 17 rotates to the point where the bend 19 contacts the pulley 21, the guide groove 18 before and after the bend 19 has a certain offset along the rotation axis of the camshaft 7. At the same time, the camshaft 7 can slide axially and the pulley 21 remains in the same position but only rotates. Therefore, the guide wheel 17 is pushed by the pulley 21, thereby driving the camshaft 7 to make axial displacement. The direction of displacement is determined by the bending direction of the bend 19 and the rotation direction of the camshaft 7, and the displacement distance is determined by the offset distance of the guide groove 18 before and after the bend 19.

[0040] Combined with appendix Figure 10 and attached Figure 11 Where v refers to the conveying direction of the fiber belt 3, and with this direction as a reference, when the camshaft 7 is attached... Figure 10 When the camshaft 7 is rotated counterclockwise as shown, the pulley 21 drives the guide wheel 17 to move the entire camshaft 7 to the right. Figure 11 When rotated clockwise as shown, pulley 21 drives guide wheel 17 to move camshaft 7 to the left as a whole.

[0041] Combined with appendix Figure 3The middle of the bottom shell 2 is provided with a holding wheel 6 which supports the fiber belt 3 from below, the upper cover 1 is provided with a pressing belt shaft 8 which is above the cam shaft 7, and the upper cover 1 and the bottom shell 2 are both provided with a plurality of guide wheels 5 which clamp and guide the fiber belt 3 from the upper and lower sides.

[0042] In combination with the accompanying drawings Figure 6 , the accompanying drawings Figure 7 , and the accompanying drawings Figure 8 , when the fiber belt 3 is not deviated, the cam shaft 7 is in the position shown in the accompanying drawings Figure 7 , and the rotation of the cam shaft 7 can make the cam 16 rise and lift the fiber belt 3 from below to above, and make the upper surface of the fiber belt 3 abut against the pressing belt shaft 8, because the folding angle 19 is arranged on the guide wheel 17 opposite to the cam 16, when the cam shaft 7 rotates to the position shown in the accompanying drawings Figure 8 , the pulley 21 will pass through the folding angle 19, because the pulley 21 can make the cam shaft 7 axially slide when passing through the folding angle 19, therefore, in the rotation process of the cam shaft 7, the cam 16 lifts the fiber belt 3 and abuts against the pressing belt shaft 8, at the same time, the cam 16 drives the fiber belt 3 to move in the same direction by the friction force of the surface of the cam 16, according to the direction of the folding angle 19 shown in the accompanying drawings Figure 9 , when the cam shaft 7 rotates clockwise, the fiber belt 3 moves to the left, and when it rotates counterclockwise, the fiber belt 3 moves to the right, each time the fiber belt 3 is corrected, the cam shaft 7 only rotates one round, the cam 16 drives the fiber belt 3 to move after rotating, and then continues to rotate with the cam shaft 7, and after rotating, it no longer forms a progression with the pressing belt shaft 8, and the fiber belt 3 moves downward and recontacts the holding wheel 6, when the fiber belt 3 still deviates after the cam shaft 7 rotates one round to correct it, the cam shaft 7 is rotated again according to the deviation direction until the fiber belt 3 is in the normal position.

[0043] In combination with the accompanying drawings Figure 3 , the bottom shell 2 is provided with a DC motor 9, the DC motor 9 drives a speed reducer 10, the output shaft of the speed reducer 10 is provided with a first gear 11, and the end of the cam shaft 7 is provided with a second gear 12 which meshes with the first gear 11.

[0044] In addition to the second gear 12 arranged at the end of the cam shaft 7, a Hall sensor which detects the number of rotations is also arranged, such sensors belong to common prior art, and the present application will not be described further.

[0045] In combination with the accompanying drawings Figure 3 , the inner side of the bottom shell 2 is provided with a spring 13, the end of the spring 13 is rotationally connected with the outer side of the second gear 12 to realize the reset of the cam shaft 7 after the axial displacement.

[0046] When the sensor detects the deviation of the fiber belt 3 and judges the deviation direction, the single-chip microcomputer controls the direct current motor 9 to rotate one circle, and selects the rotating direction of the direct current motor 9 according to the deviation direction of the fiber belt 3, so that the camshaft 7 rotates clockwise or counterclockwise, and the axial moving direction of the camshaft 7 is opposite to the deviation direction of the fiber belt 3.

[0047] In combination with the accompanying drawings Figure 4 and the accompanying drawings Figure 5 The upper cover 1 is symmetrically provided with slidable lifting supports 22 below both ends, the lifting supports 22 are provided with photoelectric sensors 4 on the sides, the photoelectric sensors 4 are distributed on both sides of the fiber belt 3, the photoelectric sensors 4 detect the edge position of the fiber belt 3, the upper cover 1 is provided with sliding grooves 15 at both ends, the lifting supports 22 are provided with sliding blocks 14 at the top, and the sliding blocks 14 and the sliding grooves 15 are provided with scale lines.

[0048] The lifting supports 22 are allowed to flexibly adjust the position of the photoelectric sensors through the sliding blocks 14, the sliding grooves 15 and the scale lines, and adapt to fiber belts with different widths.

[0050] Wherein the left deviation signal and the right deviation signal are processed by the device, and the super-wide, super-narrow and super-oblique signals are sent to the upper computer for processing.

[0051] The above describes the present application and its embodiments, which is not limited, and the actual structure is not limited thereto. In summary, if a person skilled in the art is inspired thereby, without departing from the purpose of the present application, without creative design, similar structure and embodiments to the technical solution are designed, which shall belong to the protection scope of the present application.
