Description

Technical Field

[0001] The utility model belongs to the technical field of carton manufacturing, and in particular relates to a positioning device for paperboard slotting in carton manufacturing. Background Art

[0002] Cardboard boxes can be seen everywhere in our lives. When transporting items, cartons can not only load items, but also protect them well. When making cartons, the cardboard needs to be cut and slotted, and the slotted cardboard should be folded into the required carton shape.

[0003] After searching, the Chinese utility model patent with announcement number CN211994394U discloses a positioning device for cardboard slotting in carton manufacturing, which belongs to the field of carton manufacturing technology. The device includes a body, a motor, a cutter, and a roller. The motor is installed on the body, and the output end of the motor is connected to the cutter drive through a screw rod. The roller is installed on the motor through a fixing member and is arranged close to the cutter. The fixing member is provided with a bearing, and the roller is sleeved on the bearing. The rolling direction of the roller is parallel to the cutting direction of the cutter. The utility model realizes rolling and fixing the cardboard during cutting through the setting of the roller. When the spring is in a normal state, the bottom end of the roller is lower than the bottom end of the cutter. When the cutter is about to contact the cardboard, the bottom end of the roller can first contact the cardboard to position and fix the cardboard, so as to avoid the cardboard shaking and floating upward when the cutter is cutting, etc., reduce the situation of unqualified slotting, improve the yield rate, and reduce the cost of the enterprise.

[0004] Although the above solution can press and position the cardboard through the roller when cutting the cardboard, it can only be applied to cardboard of one size when in use. In addition, since the contact surface between the roller and the cardboard is small, the positioning effect is relatively poor. In addition, when cutting the cardboard, only one groove can be cut at a time, which is less practical.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies.

[0006] Therefore, in order to solve the above problems, the utility model provides a positioning device for cardboard slotting in carton manufacturing. Utility Model Content
