Description

Technical Field

[0001] This utility model relates to the field of paperboard printing machine technology, specifically to a conveying and positioning component and a continuous paperboard printing machine. Background Technology

[0002] A printing press is a machine for printing text and images. A modern printing press generally consists of mechanisms for plate mounting, inking, printing, and paper feeding (including folding). Its working principle is as follows: First, the text and images to be printed are made into a printing plate, which is then mounted on the printing press. Ink is then applied manually or by the printing press to the areas on the printing plate containing the text and images. This ink is then directly or indirectly transferred to paper or other substrates (such as textiles, metal plates, plastics, leather, wood, glass, and ceramics), thus reproducing a printed product identical to the printing plate.

[0003] With the rapid development of the express delivery industry, corrugated cardboard printing has become a significant part of the printing industry. In the cardboard printing process, the operator first places a stack of cardboard to be printed into the feed inlet of the printing machine's conveyor belt. Then, the conveyor belt transports the cardboard sheets one by one into the printing machine for printing. However, during the transport process, the cardboard is subjected to excessive friction, which causes it to shift and affects subsequent printing processes. Utility Model Content

[0042] Working principle: First, the device is powered on. Then, the conveyor belt 302 transports the cardboard to be printed through the positioning part 2 to the printing machine body 4 for printing. During the transport process, the motor 203 drives the drive shaft 202 to rotate. The rotation of the drive shaft 202 drives the driven bevel gear 204 to rotate periodically in the counterclockwise and clockwise directions, causing the gear 205 to rotate. This causes the driven frame 206 to move horizontally left and right periodically. The rotation of the drive shaft 202 drives the driven bevel gear 204 and the gear 205 to rotate, thereby causing the gear 205 to drive the driven frame 206 to move horizontally. The roller frame 209, which is slidably set in the positioning box 207, contacts the side of the cardboard to limit the cardboard and prevent the cardboard from tilting during transport. When the roller contacts the side of the cardboard, it pushes the cardboard to perform the positioning operation. The spring 210 can prevent the roller from making hard contact with the side of the cardboard, thereby preventing damage to the cardboard.
