Apparently, the described embodiments are only some rather than all of the embodiments of the invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the invention without creative efforts shall fall within the protection scope of the invention.

[0027] Referring to FIG. 1 to FIG. 5, the invention provides an idler with an anti- deviation structure, including a bottom plate 1, where a side frame 2 is fixedly connected to each of two sides of a top end of the bottom plate 1, an end frame 3 is fixedly connected to each of two ends of the bottom plate 1, a first roller shaft 5 is clamped between two side frames 2, a second roller shaft 26 is clamped between the side frame 2 and the end frame 3, a roller cylinder 6 is rotatably connected to a surface of the first roller shaft 5 and a surface of the second roller shaft 26 through a first bearing respectively and is configured to support a transmission belt, an inclined base 15 is fixedly connected to each of two sides of a back surface of the bottom plate 1, a threaded rod 16 is rotatably connected to an inner wall of the inclined base 15 through a second bearing, a stroke 4 block 17 is in threaded connection with a surface of the threaded rod 16, a support rod 18 ~~ LU600097 is fixedly connected to a top portion of the stroke block 17, an anti-deviation roller 19 is rotatably connected to a top portion of the support rod 18 through a third bearing and may prevent deviation of the transmission belt, two connecting bases 9 are fixedly connected to two sides of an inner wall of the side frame 2 and a top portion of the end frame 3 respectively, a spring 10 is fixedly connected to an inner wall of the connecting base 9, and a limiting block 11 is fixedly connected to one end of the spring 10 which may eject the limiting block out of the connecting base 9.

[0028] During use, the threaded rod 16 in the inclined base 15 is rotated, so that the stroke block 17 on the surface and the above anti-deviation roller 19 move in an inclined direction, which can adjust a position. Therefore, the idler can adjust a distance between the anti-deviation rollers 19 on two sides according to the width of the transmission belt, to play a limiting role and prevent deviation of the transmission belt, thereby preventing materials from deviating and falling off during conveying to result in waste.

[0029] Limiting grooves 8 are formed in two sides of each of two ends of the first roller shaft 5 and two sides of each of two ends of the second roller shaft 26 respectively, and one end of the limiting block 11 is clamped with an inner wall of the limiting groove 8, to play a locking role. A middle portion of a bottom end of the limiting block 11 is provided with a bevel groove 14, a bottom end of each of the two connecting bases 9 is provided with an inserting hole 25, an inserting rod 12 is in inserting connection with an inner wall of each of two inserting holes 25 for a locking operation, and a press member 13 is fixedly connected to bottom ends of two inserting rods 12, to facilitate the operation.

[0030] During use, an end portion of the roller shaft of the idler is provided with the limiting groove 8, and after mounting, the limiting block 11 in the connecting base 9 is clamped in the limiting groove 8 under the action of the spring 10, to lock a position of the roller shaft, thereby preventing the roller shaft from shifting and shaking during working to affect operation stability of the transmission belt.

The disposed guide rail 22 and the guide block 21 can play a guiding role in movement of the stroke block 17, to enable the stroke block to move linearly only. The disposed rotary knob 20 facilitates rotating the threaded rod 16, and the disposed pointer 28 and scale 27 can ensure symmetrical positions of the anti-deviation rollers 19 on two sides.

[0033] During specific use, according to the idler with an anti-deviation structure of the invention, the rotary knob 20 on each of two sides of the back surface of the idler is rotated, to drive the threaded rod 16 in the inclined base 15 to rotate, so that the stroke block 17 on the surface and the above anti-deviation roller 19 can move in an inclined direction under guidance of the guide block 21 and the guide rail 22, which can adjust the position.

Therefore, the idler can adjust the distance between the anti-deviation rollers 19 on two sides according to the width of the transmission belt and play the limiting role to prevent deviation of the transmission belt, thereby preventing the materials from deviating and falling off during conveying to result in waste.
