[0002] The application of the box gluing machine is the last process of the packaging box processing, which is to fold the printed and die-cut cardboard into shape and glue it. In the prior art, a variety of paper feeding mechanisms for box gluing machines have been proposed, such as a high-reliability paper feeding mechanism for box gluing machines proposed in the Chinese utility model patent with publication number CN215792029U. The paper feeding mechanism is provided with a number of rollers on both sides of the conveyor belt, and the motor drives the rotating shaft to rotate, and drives a number of synchronous transmission wheels to rotate through the chain belt, so that the several rollers rotate synchronously, and the rotation speed of the rollers is equal to the speed of the conveyor belt. In the process of continuous conveying of the raw paper box, the several rollers are also continuously rotating, so that the relative friction is reduced in the process of contact between the rollers and the raw paper box, thereby greatly avoiding the probability of damage to the raw paper box.

[0003] However, the paper feeding mechanism of the above-mentioned box gluer, like other existing technologies, mainly transports the raw paper boxes through a conveyor belt. Since the conveying of the conveyor belt is continuous, it is not convenient to feed paper at a certain beat interval, which is not conducive to the box gluer to perform the specified beat feeding operation on the raw paper boxes, and the stability is poor.

[0022] After adjusting the position of the positioning slider 8, tighten the locking bolt 9 to lock the positioning slider 8 on the slide rail 3. The positioning slider 8 limits the forward stroke of the slide 4 and adjusts the position of the raw material cardboard entering the conveyor belt 2. During operation, the raw material cardboard is placed on the support plate 5, and multiple rollers of the roller frame 6 support the raw material cardboard. The push rod 7 extends to move the support plate 5 and the slide 4 along the slide rail 3 toward the conveyor belt 2. When the slide 4 reaches the set position and is blocked by the positioning slider 8, the push rod 7 continues to extend to push the front end of the support plate 5 upward and lift it up, so that the raw material cardboard can be put on the conveyor belt 2.
