The working process is as follows: the initial state is as shown in fig. 10, sets up the distance from the belt to the induction mechanism, makes the induction mechanism contact with the material, starts this device, and the belt moves forward (the lower left shown in fig. 1 is preceding, the upper right is the back) by the back, puts in the material to the belt, because only downside contact material, so when the material moves forward from the back along with conveyer belt 13, can order about to dial material portion clockwise turning. When the left and right sides of the induction plate 4 of a certain group of induction mechanism induces resistance with different sizes, the material on the side with large resistance is distributed thickly, so that the material on the side needs to be guided to the other side. And the induction plate 4 on the side with large resistance contacts the material through the inclined surface 41 thereof and is jacked up by the material, thereby promoting the two sliding columns 51 at the lower end of the first telescopic cylinder 5 with the large thickness end to slide in the T-shaped sliding grooves 43, and extruding the first pressure spring 44, further stretching or compressing the tension spring 53, driving the first telescopic cylinder 5 with the large thickness end to stretch, further ensuring the induction plate 4 of the induction mechanism to swing in the left-right direction, meanwhile, because the telescopic rod 92 can drive the second telescopic cylinder 8 to stretch synchronously, ensuring the second telescopic cylinder 8 to swing as same as the first telescopic cylinder 5, changing the angle of the half gear 82 and the side gear 73, and ensuring the clockwise rotation of the telescopic plate 71 as the half gear 82 and the side gear 73 are meshed.

When the guiding mechanism rotates until the bottom end of the retractable plate 71 contacts the material (as shown in fig. 11), the side with the higher thickness can slide to the side with the lower thickness, that is, the material on the side with the higher thickness is guided to the other side. When the sensing mechanism senses different thickness differences, the guiding effect of the guiding mechanism is different. When the thickness difference is large, the inclination of the induction plate 4 is large, the rotation angle of the expansion plate 71 is large, the inserted material is deep, the whole pressure of the locking mechanism 6 against the cam groove 24 is large, the friction force is large, the guiding time is long, and the guiding effect is strong. When the thickness difference is small, the inclination of the induction plate 4 is small, the rotation angle of the expansion plate 71 is small, the inserted material is shallow, and the guiding effect is weak. The lock mechanism 6 has a small pressure against the cam groove 24, a small friction force, a short guide time, and a weak guide effect. Consequently the conveyer of this application can produce different guide results according to the thickness difference's of material variation in size, adjusts automatically, and the practicality is strong and the reliability is high.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
