Description

Technical Field

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

[0002] The paper feeding device for carton printing is an important part of the carton printing machine. Its main function is to accurately feed the cartons to be printed from the paper feeding device to the printing part. The design of the paper feeding device usually ensures the smooth feeding and correct position of the cardboard to ensure the normal progress of the subsequent printing steps. Specifically, the paper feeding device may include a feeder, a guide plate and a transmission device. The feeder usually consists of a paper feeding roller shaft, a cardboard clamping device and a feed roller device, which is responsible for clamping and conveying the cardboard. The guide plate is used to guide the cardboard transmission device above the correct position of the cardboard in the feeder to ensure stable feeding of the cardboard. The transmission device is responsible for driving the feed roller device to feed the cardboard to the next processing link.

[0003] At present, when cartons are printed and conveyed, the cartons are generally pushed onto conveyor rollers for conveying by mechanical push plates. However, conveyor rollers are generally smoother to reduce wear during carton conveying. As a result, when the carton contacts the conveyor rollers, the friction between the conveyor rollers and the carton is small, causing the carton to slide and deviate, making it impossible to convey the carton to the specified position, thereby affecting the efficiency of carton conveying. Therefore, a carton printing and paper feeding device is proposed. Utility Model Content

[0009] Furthermore, a support frame and a discharge plate are fixedly installed on the left and right outer walls of the carton conveyor frame respectively. The support frame is a right triangle and the top is fixedly installed on the bottom of the discharge plate. The discharge plate is inclined from the upper left to the lower right.

The support frame 8 is a right triangle and the top is fixedly mounted on the bottom of the discharge plate 7, and the blanking plate 20 is inclined from the upper left to the lower right.

At this time, start the servo motor 16 to drive the bidirectional threaded rod 17 to rotate. At this time, the adjustment seat 18 moves and drives the adjustment rod 19 and the first limit plate 4 to adjust the position. At this time, the two first limit plates 4 will move in a close or far direction. At this time, the second limit plates 6 are driven to adjust the position synchronously through the connecting rod 5, and then the carton is placed on the top of the discharge plate 7. At this time, start the linear module 9 to drive the electric telescopic rod 10 to move downward. At this time, the push plate 14 moves downward synchronously. When the push plate 14 is attached to the top of the discharge plate 7, the electric telescopic rod 10 drives the push plate 14 to move to the right. At this time, the carton is limited by the first limit plate 4 and the second limit plate 6 so that it cannot be offset.
