AI Technical Summary

Technical Problem

In existing perfect binding machines, uneven temperature on the outer wall of the glue wheel module leads to reduced bonding performance, affecting the bonding effect between the book and the cover, and reducing the quality of bookbinding.

Method used

The design incorporates an oil cavity and a flow ring cavity within the rubber roller. Through centrifugal force connecting the groove and the sealing component, the oil flows within the flow ring cavity, uniformly transferring heat, stabilizing the roller temperature, and enhancing the adhesive properties of the rubber compound.

Benefits of technology

It improves the temperature stability of the outer circumferential wall of the rubber roller, enhances the adhesion between the book and the cover, improves the quality and efficiency of bookbinding, and reduces oil waste and cleaning frequency.

Abstract

The application relates to a gluing device of a bookbinding machine and the bookbinding machine, which comprises a glue pot and a glue roller, the glue pot is provided with a cavity, the glue roller is provided with an oil cavity and a flow ring cavity, a communication groove is arranged on the cavity wall of the oil cavity close to the flow ring cavity, a sealing assembly is arranged on the groove wall of the communication groove, and the sealing assembly comprises a first elastic member and a sealing block. In the application, the glue roller, the oil cavity and the flow ring cavity are arranged, the temperature of the circumferential outer wall of the glue roller is stable, the glue material adhered to the circumferential outer wall of the glue roller keeps stable bonding performance, the adhesion of books and covers is improved, and therefore the quality of bookbinding is improved; the second elastic member and the opening and closing block are arranged, the oil liquid in the flow ring cavity is not easy to flow back into the oil cavity from the oil liquid channel, and therefore the stability of the oil liquid flowing in the flow ring cavity is improved; the second thermal expansion and cold contraction block is arranged, the flow speed of the oil liquid in the oil cavity into the flow ring cavity from the through groove is accelerated, and the stability of the temperature of the glue roller is further improved.
