Problems solved by technology

[0003] When the existing full-circle mold processes the ridge of the book block, the ridge of the book block is processed into a full circle by pressing the rolling wheel, but the unit contact area of ​​the rolling wheel is small, and the contact with the book block is difficult. is a linear contact, resulting in a general efficiency of the full circle

Embodiment Construction

[0034] The present invention will be described in detail below with reference to the accompanying drawings.

[0035] like Figure 1-6 As shown, an arc-shaped rounding mechanism for rounding the spine of the book block includes a full-round mold 1 for fitting the spine of the book block, and the full-round mechanism also includes a full-round mold 1 for driving the round mold 1 The arc-shaped swinging arc drive mechanism 2 and the longitudinal drive mechanism 4 for longitudinal movement; the full-circle mold 1 includes a mold assembly 10 and a guide mounting seat 18 for installing the mold assembly 10. The mold assembly 10 includes an arc-shaped track 12 and a The arc-shaped friction surface 11 which is in frictional contact with the spine of the book block in an arc-shaped motion, and the guide mounting seat 18 is provided with a guide moving piece that moves on the arc-shaped track 12 .

[0036] After the book block is clamped and positioned on both sides by the clamping mec...

Abstract

The invention relates to the technical field of book block back processing, in particular to an arc-shaped rounding mechanism for rounding a book block ridge, which comprises a rounding die for fitting a book block, and further comprises an arc-shaped driving mechanism for driving the rounding die to perform arc-shaped swing and a longitudinal driving mechanism for performing longitudinal motion; the rounding die comprises a die assembly and a guide mounting seat used for mounting the die assembly, the die assembly comprises an arc-shaped track and an arc-shaped friction surface which makes friction contact with the ridge part of the book block in an arc-shaped motion mode, and the guide mounting seat is provided with a guide moving part moving on the arc-shaped track; after the book block is in place, the whole circle mold descends as a whole, and the arc-shaped friction surface is attached to the ridge part of the book block, the mold assembly moves along the guide moving part through the arc-shaped track, so that the arc-shaped friction surface is attached to the ridge part to press and swing, the ridge part with radian is formed, due to surface contact movement, the contact range is larger, the formed arc surface is more uniform, and the service life of the whole circle mold is prolonged. The radian is smoother, and the quality is better.

Description

technical field [0001] The invention relates to the technical field of processing the back of a book block, in particular to an arc-shaped rounding mechanism for rounding the spine of a book block. Background technique [0002] After the ridge on the back of the book block is processed by the pre-rounding station, the ridge of the book block is formed with a preliminary arc surface, and the subsequent rounding needs to be carried out by the mold to form a relatively smooth arc surface. [0003] When the existing round molds process the ridge of the book block, the ridge of the book block is rounded by the pressing of the rolling wheel, but the unit contact area of ​​the rolling wheel is small, and the contact area with the book block is too small. is a linear contact, resulting in average efficiency for a full circle. SUMMARY OF THE INVENTION [0004] The purpose of the present invention is to provide an arc-shaped rounding mechanism for rounding the spine of the book blo...
