[0002] Generally, an integral pressing roller is used on the folder gluer to compact the paper box. Figure 1 The figure shows the structure of the traditional paper pressing roller of the box gluing machine, which includes two parallel upper pressing rollers a and lower pressing rollers b. At the same time, two pressing wheels c are installed on the upper pressing roller a. The specific working principle is: adjust the left and right and up and down positions of the pressing wheel c to the appropriate positions, and the entire paper box conveyed is located between the upper pressing roller a and the lower pressing roller b. The pressing wheel c and the lower pressing roller b apply pressure together to compact the second and fourth lines of the conveyed paper box.

[0003] The traditional paper pressing roller structure of the box gluer has the following disadvantages: 1. Due to the use of a long pressing roller, the entire paper box passes between the two pressing rollers, which easily leaves scratches on the paper box and reduces the product qualification rate; 2. This paper pressing roller structure has high requirements on the processing straightness of the upper pressing roller a and the lower pressing roller b, and the parts processing is difficult and the processing cost is high; 3. Due to the processing error of the straightness of the upper pressing roller a and the lower pressing roller b, the running speed of the entire box gluer will be affected, and the box gluer cannot be reliably accelerated, which affects the stability of the operation of the box gluer.
