Carrier roller frame capable of adjusting gradient

A carrier roller frame capable of adjusting inclination comprises a carrier roller frame body, the carrier roller frame body of the carrier roller frame is in a cattle-yoke-like shape with the middle straight and the two ends inclining outwards, a shaft frame for installing a main carrier roller and a side carrier roller is arranged on the cattle-yoke-like carrier roller frame body, and a linear connector is arranged on the straight portion of the carrier roller frame body. A carrier roller frame body is hinged to a U-shaped cross beam through a linear connector and a pin shaft I, a lead screw is rotationally fixed in a U-shaped groove of the U-shaped cross beam, a nut type sliding block is arranged on the lead screw in a rotating mode, a connecting rod is hinged between the nut type sliding block and an inclined section on one side of the carrier roller frame body through a shaft II, and the lead screw is rotated to drive the nut type sliding block to move on the lead screw. Therefore, the inclination of the
