Gluing and binding machine

Abstract

The present invention relates to the field of printing equipment technodlogy. The gluing and binding machine includes page distributing mechanism, cover page conveying mechanism, vibrating and tidying mechanism and gluing and binding formation mechanism combined by a conveying belt into an integral and controlled by a programmed controller. The page distributing mechanism comsists of one or more page distributing conveying belts and several paper suckers; the cover page conveying mechanism consists of paper sucking and impressing wheel; the vibrating and tidying mechanism consists of vibrating cylinder driven paper sucking disc; and the gluing and binding formation mechanism consists of chain driven by chain wheel, support board, paper preheater, glue sprayer and setter.

Description

technical field [0001] The invention belongs to the technical field of printing equipment, and in particular relates to the structural improvement of a perfect binding machine. Background technique [0002] There are many types of arrangement forms of existing perfect binding machines, but the basic composition is similar. Its main structure is as figure 1 As shown, it includes a collating mechanism 1 connected by a conveyor belt 10, a turning and erecting mechanism 2, a milling mechanism 3, a roughening mechanism 4, a book block gluing mechanism 5, a cover mechanism 6, a pressure forming mechanism 7 and The three-side cutting mechanism consists of 8 (the first edition of "Postpress Technology" issued by China Light Industry Press in October 2001). The working process is as follows: after the signatures are collated by the collating unit 1, a book block is formed; the book block is turned over by the flip-up mechanism 2, positioned, and clamped by the book clip into the mi...

Problems solved by technology

This heating method takes a long time, and the hot melt adhesive is heated unevenly, and the hot melt adhesive itself is a mixture of low-melting wax, rosin, etc., which are easy to evaporate and reduce the viscosity of the glue. The difference in temperature is too large, so that the temperature of the hot melt adhesive drops too quickly, resulting in insufficient bonding; on the other hand, it is determined by other processes to directly apply glue to the back of the book, and the bonding area is small. At the same time, it is difficult to use roller coating at the same time. Guaranteeing the least dosage and the most uniform effect often results in the phenomenon of thick backs. In addition, a certain amount of pressure is required for bonding, and the roller coating film is too thick to be pressurized, so that the book binding must be firm first, and second, it must be flattened. It is difficult to guarantee the basic use requirements for easy reading, and quality problems such as falling apart and falling pages, brittleness in winter, difficulty in opening, and deformation of the spine often occur (Chemical Industry Press "Post-press Processing" 1st edition in September 2001)
