Technical Field

The invention relates to printing equipment, in particular to a card book deformation-preventing joint die capable of preventing a card book from deforming after mounting by controlling the gluing shape, and belongs to the field of printing equipment.

Background

The card book is mainly used for making autograph books, atlas, stamp books, collection books and the like, and due to the limitation of use performance and structure, the inner page of the card book needs to have thicker size, higher strength and hardness, and meanwhile, the card book also needs to have good support performance and difficult deformation.

When the existing card book is manufactured, the inner page of the existing card book is evenly glued through a rubber roller with a smooth surface, then the inner page is mounted through a mounting machine, and finally the mounted inner page is bound into a book to finish the card book manufacturing. The rubber roller with the smooth surface has high speed and high efficiency during gluing, but the gluing amount is not easy to control, phenomena such as glue leakage, glue leakage and the like are easy to generate, meanwhile, after the glue is wholly rolled, a large amount of water is contained in the glue to easily wet the page to be mounted, and the contraction force generated during the solidification of the glue can also cause the page to be mounted to generate phenomena such as folds, unevenness and the like, so that the attractiveness and durability of the card book are seriously influenced, the card book yield is low, and the card book quality is greatly influenced and limited.

In order to avoid the problems, in recent years, a local gluing mode is used to replace integral glue rolling in the printing industry so as to reduce the gluing amount of the inner page of the card book when the inner page is mounted, and avoid the problem of stress concentration in the later period.

Therefore, it is a main problem to be solved by the present invention to design a card book deformation prevention engagement mold that can prevent the card book from deforming after mounting.

Disclosure of Invention

In view of the existing situation, the invention aims to provide a book clamping deformation-preventing jointing die which is based on the premise of locally gluing a mounting surface and effectively controls the problems of gluing amount, stress concentration after gluing and the like by controlling the shape of the gluing, so as to meet the requirement on the flatness of inner pages of the mounted book clamping and avoid the problems of stress concentration, glue leakage, wetting and the like.

The invention is realized by the following technical scheme:

the book clamping deformation-preventing jointing mold includes one carrier, one glue coating layer covering the glue coating surface of the carrier, lugs with closed outer contour and distributed homogeneously on the glue coating layer, and the raised distribution density is set based on the glue area for mounting the inner page of the book clamping.

The carrier is flat, and the lower surface of the flat carrier is a working surface; or, the carrier is cylindrical, and the outer circle surface of the cylindrical carrier is a working surface.

The outer contour of the protrusion is circular.

The protrusions are cylindrical or spherical.

The height of the protrusion is more than or equal to 3 mm.

The book clamping deformation-preventing jointing die has the beneficial effects that:

1. the soft rubber and the bulges are arranged on the working surface of the carrier, so that the elasticity and the flexibility of the working surface of the carrier are improved, the service life and the service performance of a jointing die are prolonged, and friction damage is avoided;

2. the bulges with closed outer contours are arranged on the rubber, so that the offset printing after gluing forms independent closed bodies, the phenomenon of mutual stress concentration between the offset printing when the glue is dried and contracted is avoided, the flatness of the inner page of the mounted card book is ensured, and the situations of deformation, wrinkles and the like are avoided;

3. the circular raised outer contour has a good stress range, the stress of the circular raised outer contour is relatively closed, concentrated and uniform, the influence on the internal stress of the mounted inner page of the card book is small, and the influence on the flatness of the inner page of the card book is reduced to the maximum extent;

4. practice proves that the finished mounting card book has stable quality and high flatness, is not limited by the size of the card book, can not deform or fold after long-term use, and obviously improves the quality.

Detailed Description

The invention is described in further detail with reference to the accompanying drawing 1:

the book clamping deformation-preventing jointing die comprises a cylindrical metal carrier, wherein a layer of rubber 1 covers the outer circle surface of the cylindrical metal carrier. The rubber sheet 1 is used as a gluing working surface, and bulges 2 with round outline are uniformly distributed on the rubber sheet. In this example, the shape of the protrusion 2 is spherical, and the diameter of the circular outer contour of the protrusion 2 is 4 cm. The surface of the spherical bulge 2 is smooth, so that the friction damage can be avoided while gluing, and the durability of the bulge 2 is improved. To ensure that the gluing process is carried out reliably, the height of the protrusions 2 is 5 mm. According to the requirement of the gluing amount and the requirement of the water content of the inner page of the card book, the bulges 2 are uniformly distributed on the rubber 1 at intervals of 3 cm.

Of course, the carrier can also be flat, the lower surface of the flat carrier is a working surface, and the inner page of the card book is glued from top to bottom through the lower surface. The convex shape can also be cylindrical, the elasticity of the cylindrical convex is better, the gluing performance can be effectively improved, and the gluing quality is ensured.

When specifically carrying out card book to mount, cylindric metal carrier keeps the rotation state all the time under external drive mechanism's drive, and rotatory in-process external glue is constantly covered on the protruding 2 surface of sphere form, and along with treating rubberizing card book interior page or leaf and constantly conveyed cylindric metal carrier below, glue on the arch 2 is constantly renditioned on the card book interior page or leaf to accomplish the continuous rubberizing process of card book interior page or leaf. The gluing shape on the inner page of the card book is a round shape with a closed outer contour, and the round gluing offset printing is distributed on the inner page of the card book in a uniform arrangement mode, so that the glue consumption is reduced, the situations of glue leakage, soaking and the like are avoided, the phenomena of stress concentration and the like of the locally glued glue in the drying and shrinking processes are reduced due to the closed outer contour, the flatness of the mounted card book is finally ensured, the mounting quality is improved, and the mounted card book is not easy to deform and wrinkle.
