Description

Technical Field

[0001] The utility model relates to the technical field of printing carton positioning, in particular to a carton printing positioning device. Background Art

[0002] Cartons are the most widely used packaging products. Depending on the materials used, there are corrugated cartons, single-layer cardboard boxes, etc., with various specifications and models. After the cartons are printed and manufactured, a positioning device is required to transport the finished cartons.

[0003] After searching, it was found that the announcement number is CN218143770U, and the name is a printed carton positioning device. The application proposes that in the existing carton printing production, the placement of cartons is usually done manually, but when the cartons are placed manually, the placement position of the carton and the position of the product will usually deviate. If the position of the carton is adjusted manually at this time, not only can the position of the carton not be guaranteed to be accurately adjusted, but the personal safety of the operator cannot be guaranteed. The problem of poor safety is solved by setting up cylinders, moving rods, limit columns, arc plates, support rods and side guide wheels. Starting two cylinders will drive the two connecting rods connected to their output shafts to move relative to each other, and the distance between the two connecting rods will gradually decrease, thereby bringing the two arc plates closer together. Therefore, the distance between the two arc plates can be adjusted by starting the two cylinders, and the printed carton The carton is transported at the middle position of the two arc-shaped plates. The moving support rod can drive the magnet sleeve magnetically connected to it to move, thereby driving the side guide wheel to move. Therefore, the distance between adjacent side guide wheels can be adjusted, and the movement of the carton on the surface of the positioning device body can be limited to prevent the carton from deviating. However, in actual use, the application requires manual adjustment, and manual adjustment is difficult to control the distance of movement of the side guide wheel. At the same time, there are two cylinders, and the working synchronization of the two cylinders is difficult to maintain, which makes it difficult to control the centering movement of the carton and easily produces movement offset errors, affecting the accuracy of the position. At the same time, the manual adjustment process is also more cumbersome and the structure is more complicated, and further improvements can be made. At the same time, the application lacks a stop structure for the carton, and the triggering of the printing mechanism still needs to rely on additional sensing equipment, which increases the complexity of use, and further improvements can be made.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content
