The purpose of the utility model is to overcome the shortcomings of the existing technology and provide a deviation correction mechanism of the carton folding and gluing machine, which can improve the box pasting accuracy of the corrugated box, and improve the product quality and processing efficiency. The technical solution for achieving the above objective is a correcting mechanism of a carton folding and gluing machine, which is installed between the paper feeding part cover and the pre-folding part cover of the carton folding and gluing machine. The correction mechanism includes a movable wall panel, a lower pressing wheel group, an upper pressing wheel group, a supporting gauge and upper and lower indicating boards. The movable wall board is fixed on the side wall board of the paper conveying section of the carton folding and gluing machine. A long slot is cut horizontally in the middle of the rear end, so that the movable wall panel is divided into upper and lower halves, and the uncut part of the front part of the movable wall panel is used as the rotation axis. The lower pressing wheel group is installed in parallel and spaced on the upper end surface of the upper movable wall panel, and a lower conveyor belt is wrapped on the lower pressing wheel group; the upper pressing wheel group is installed in parallel and spaced apart on a rocker, which passes through A concave connecting plate is connected to the lower half of the movable wall plate, and an upper conveyor belt is wrapped around the upper pressing wheel group, so that the upper conveyor belt is located tangentially above the lower conveyor belt; the supporting gauge is connected to the lower half through two transition plates The movable wall board and leaning against the side of the lower conveyor belt; the lower indicating board is a right-angled board, which is installed on the lower half of the movable wall board, and the upper surface of its horizontal part is provided with scale marks; the upper indicating board is also a right-angled board, It is installed on the upper movable wall plate corresponding to the position of the lower indicating board, and its horizontal part is connected with the lower indicating board through a positioning screw. In the deviation rectifying mechanism of the carton folding and gluing machine, the movable wallboard is made of high plastic material, so that the upper part of the movable wallboard can rotate with the rotation axis as the axis. The technical scheme of the deviation rectifying mechanism of the carton folding and gluing machine of the utility model can correct the deviation of the carton by 7mm at most, and the deviation rectifying datum can be arbitrarily changed between the transmission surface and the operation surface, which greatly increases the flexibility in the actual operation, and improves the production efficiency and the pasting precision of the carton folding and gluing machine.
