Technical Field

[0001] The utility model relates to the technical field of carton printing, in particular to a carton printing and forming production line which is convenient for paper feeding adjustment. Background Technique

[0002] Cartons are ordinary paper packaging products that are inseparable from our life and production. The printing quality of cartons not only affects the appearance quality of cartons, but also affects the sales prospects of the packaged products and the image of commodity production enterprises. When printing existing cartons, usually only one side can be printed. When double-sided printing is required, workers need to manually turn them over.

[0003] Since the existing carton printing production line can achieve batch printing of cartons, it is necessary to ensure that the cartons are conveyed to the lower part of the printing machine at the same position before printing the cartons. However, due to deviations during the conveying process, it is necessary to adjust the position of the cartons before paper feeding. Generally, it is necessary to convey them in the center. The prior art will adopt a structure that moves towards each other in two directions to drive the limiting plates to approach the middle simultaneously, so as to be able to move the cartons to the center position. However, due to the difficulty in accurately controlling the moving position, the cartons are often squeezed and deformed, thus affecting their printing quality.

[0004] Based on this, this solution proposes a carton printing and forming production line which is convenient for paper feeding adjustment. Content of the Utility Model

At the same time, it will also control the paper feeding adjustment member 8 to work to adjust the position of the limiting roller 805. During use, the position of the limiting roller 805 can be limited according to the width of the carton by the distance measuring instrument 11, so that after the position adjustment of the carton is completed, it can be conveyed in the center to ensure the printing quality. Then, the rotating member 5 arranged works. The motor 502 works to drive the second conveying frame 6 to rotate. The carton can slide under the action of gravity, so that one side of it is flush with the limiting roller 805. Then, the rotating member 5 rotates in the reverse direction, which can make the second conveying frame 6 return to its original position. Finally, the second conveying member 9 works. The second electric telescopic rod 901 extends to drive the third conveying frame 903 to descend. The third conveying roller 904 can extrude the carton. When the pressure sensor 902 detects that the pressure value reaches the set value, it will send a signal to the controller 4. The controller 4 will then control the second electric telescopic rod 901 to stop extending. Then, under the action of the corresponding driving structure, the third conveying roller 904 rotates to drive the carton forward. Then, printing it can form a complete production line.
