Description

Pre-flanging device for flanging machine

Technical Field

The utility model belongs to the technical field of the technique of flanging machine and specifically relates to a hem device in advance for flanging machine is related to.

Background

The processing of books and periodicals generally comprises the following steps: plate making, printing, page gathering, back milling, hot melt adhesive coating, cover sticking and edge folding to finally obtain the finished book. The edge folding process is mainly completed by a folding machine, and the edge part of the front cover is turned into the inner side of the book cover and is stuck and fixed.

Chinese patent publication No. CN206951900U discloses a folding mechanism with liftable limit, which comprises a folding frame, a pressing table, a pressing die strip, a die strip roll-over stand and a limit mechanism. The material pressing platform, the material pressing die strip and the die strip overturning frame are arranged on the flanging machine frame. Wherein, the material pressing die strip is positioned right above the material pressing platform and is driven by the cylinder to lift. The die strip overturning frame is provided with a flanging die strip and is driven to overturn by an overturning driving mechanism. The limiting mechanism comprises a lifting cylinder, a cross frame beam and a blocking column. The retaining columns are vertically arranged below the cross frame beam. The cross frame beam is arranged on the flanging frame through the lifting cylinder and is positioned above the die strip overturning frame, so that the blocking column can be driven by the lifting cylinder to lift and can be pressed on the die strip overturning frame. The position that needs the hem is arranged in and is pressed the material bench, and the lifter plate is under the drive of pressing the material cylinder, goes up and down along vertical slide rail, and then drives and press the material mould strip and go up and down. Through going up and down, press the material mould strip and can press on pressing the material platform. The turnover driving mechanism drives the die strip turnover frame to turn over, and the edge folding process is completed.

The above technique has the following disadvantages: before the hem, the books need one side of hem to be arranged in under the mould strip roll-over stand, but because the front cover is located a plane with the book cover surface after pasting, the mould strip roll-over stand rotates and can't directly turn up the hem with the front cover, consequently needs in the operation process to manually turn over its front cover, forms the angle of folding in advance, just can carry out the hem process, leads to the hem inefficiency.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a hem device in advance that is used for flanging machine that hem efficiency is higher not enough to prior art exists.

The above utility model discloses an above-mentioned utility model purpose can realize through following technical scheme: the utility model provides a hem device in advance for flanging machine, includes the workstation, sets up and rotates along workstation length direction and connects in the upset strip of workstation and be used for driving upset strip pivoted revolving cylinder, install folded plate in advance between workstation and the upset strip, the folded plate cross-section is the V-arrangement in advance, forms the hem chamber that supplies book cover and front cover embedding, and when upset strip corner was 90 degrees, a lateral wall of upset strip offset completely with the front cover.

Through above-mentioned technical scheme, the cover is generally the harder cardboard of material, and one side orientation that will need the hem is folded the board in advance, before the embedding, the front cover is arranged in on the board of folding in advance, and this side cover imbeds to the hem intracavity, and the embedding in-process, the front cover turns over to the book skin in turn over, forms the hem in advance. At the moment, the rotary cylinder is started, the piston rod at the end part of the rotary cylinder drives the turnover strip to rotate to be abutted against the cover turned inwards, the cover covered with glue in advance is compressed, and edge folding is completed. Before the complete edge folding, the edge folding cavity is embedded to carry out edge pre-folding, manual pre-folding is not needed, and edge folding efficiency is improved.

The present invention may be further configured in a preferred embodiment as: and an elastic abutting strip for abutting against the side wall of the book cover is arranged on one side of the small end in the folding cavity.

Through above-mentioned technical scheme, because the cover itself has certain thickness, when carrying out hem in advance to the front cover, the cover embedding hem intracavity, the cover lateral wall offsets with the butt strip, makes the cover lateral wall fully paste with the front cover, has improved the quality that the hem was pasted.
