Description

Technical Field

[0001] The utility model relates to a paper guiding device for printing and packaging equipment, belonging to the technical field of packaging equipment. Background Art

[0002] According to its use, conventional paper can be roughly divided into the following categories: packaging paper; printing paper; industrial paper; office and cultural paper; household paper; and special paper.

[0003] After searching, a Chinese patent with publication number CN215363972U discloses a paper guiding device for printing and packaging equipment, and its technical points are: a paper guiding device for packaging equipment, servo motors arranged opposite to each other are fixed on the left and right sides of the inner cavity of the flattener, and the output ends of the two groups of servo motors are fixedly equipped with reducers, and the output ends of the reducers are fixedly equipped with screws, and a bidirectional bearing seat movably assembled with the other end of the screw is fixed in the middle of the inner cavity of the flattener, and a sliding rod slidably assembled on the inner wall of the flattener is screwed on the outer wall of the screw, and a guide channel compatible with the sliding rod is opened on the front side wall of the flattener, and a mounting frame is fixedly assembled after the front end of the sliding rod extends out of the guide channel, and a flattening wheel is movably assembled on the mounting frame to improve the flattening degree of the paper, and can be adjusted according to the different thicknesses of the paper to adapt to different materials and paper lengths, thereby improving work efficiency.

[0004] The above solution solves the problem that traditional paper is prone to wrinkles and tearing during guidance, and the operator must adjust the printing and packaging machine in a timely and fast manner based on experience. However, since the flattening wheel flattens the paper by moving to both sides of the paper, the paper can only be flattened when it stops moving, resulting in low flattening efficiency. It is very easy to damage the paper when working while it is moving.
