Description

a cutting machine

technical field

The invention relates to a pressing and cutting machine, which is used for trimming bound books.

Background technique

After the book binding is completed, the bound book needs to be trimmed to ensure that the trimmed edges of the bound book are neat. The method that the existing bound book trimming adopts is that the bound book is manually stacked to press the binding side of the bound book, and a hydraulic cutter is used to trim the bound book of a stack. Due to the limited labor force, the bound book is prone to deviation during the trimming process. At the same time, the bound book is not flattened after binding, resulting in a decrease in the uniformity of the trimmed edge.

Contents of the invention

The technical problem to be solved by the present invention is to provide a press-cutting machine in view of the current state of the prior art, which can prevent the bound book from running off and realize the flattening of the bound book when trimming the bound book.

The technical solution adopted by the present invention to solve the above-mentioned technical problems is: a press-cutting machine, including a machine case, a conveying table arranged in the machine case, and a paper cutting mechanism arranged on the conveying table, the paper cutting mechanism includes a knife rest and a set The cutter on the knife rest is characterized in that: a first guide column is arranged on the knife rest along the moving direction of the cutter, and a first pressing plate is arranged below the first guiding column, and the first pressing plate and the knife rest A first spring is arranged between them, and a connecting rod is arranged on the knife rest along the conveying direction, and a paper pressing assembly is arranged on the connecting rod, and the paper pressing assembly includes a second pressing plate for flattening the bound book, and a first pressing plate Level with the height of the second platen.

As an improvement, the paper pressing assembly further includes a connecting plate arranged on the connecting rod, a second guide column connected to the second pressing plate is arranged on the connecting plate, a second spring is arranged on the second guiding column, and by setting The second spring makes the second pressing plate slowly compress when the second pressing plate touches the binding edge of the bound book, so as to improve the flattening effect.

As a further improvement, the paper pressing assembly also includes a sliding frame arranged above the connecting plate, guide grooves are formed on the opposite inner wall of the cabinet, sliding bars are formed on opposite sides of the sliding frame, and the sliding bars are slidably arranged on the guide In the groove bar, an indicator is arranged on the sliding frame, a scale opposite to the indicator is arranged on an inner side wall of the cabinet, the connecting plate is slidably arranged on the connecting rod, and the connecting plate is provided with a For the locking bolt that locks the connecting plate and the connecting rod, slide the connecting plate on the connecting rod. After loosening the locking bolt, the connecting plate can slide on the connecting rod according to the size of the binding book, and the sliding frame follows For movement, use the indicator on the sliding frame to indicate the moving distance of the connecting plate, so that the distance between the first pressing plate and the second pressing plate can be adjusted according to the size of different bound books.

As a further improvement, the paper platen assembly is provided with a paper retaining assembly on one side of the conveying direction, and the paper retaining assembly includes a retaining plate located outside the second platen for blocking the bound book, a pull bar connected to the retaining plate, and a The top of the pull rod is used as an electromagnet to pull up the pull rod. The two sides of the baffle are rotated and set on the sliding frame. The baffle, if the bound book is in an inclined state, one end of the bound book will touch the baffle first, and at the same time, as the conveying table continues to transport, the other end of the bound book will also contact the baffle, so that the bound book will One side of the binding edge is completely attached to the side wall of the baffle, which realizes the fine-tuning of the position of the binding book before trimming and ensures the neatness of the trimming. Finally, after the trimming is completed, the electromagnet is energized, and the pull rod is in the electromagnetic Under the action of the iron, it is moved upwards, and the pull rod drives the baffle to rotate on the sliding frame. The side of the baffle blocking the bound book is lifted, and the bound book is transported outward. After that, the electromagnet is de-energized, and the baffle is reset again.

As a further improvement, the first pressing plate is provided with a tongue-pressing piece for touching and pressing the bound book, and by setting the tongue-pressing piece on the first pressing plate, one end of the tongue-pressing piece is pressed tightly against the middle of the bound book, effectively preventing the The bound book is misaligned.

Further improvement, the quantity of the tongue depressor is two, and the front end of each tongue depressor is zigzag, and the front end of the tongue depressor is set into a zigzag shape, so that the tongue depressor and the bound book realize multi-point contact, improving The ability to prevent deviation.

Compared with the prior art, the present invention has the advantages that: when the bound book enters the paper-cutting mechanism, the knife rest moves downward, and the knife rest drives the paper pressing assembly through the connecting rod, and the knife rest and the paper pressing assembly realize linkage. Before trimming the bound book, the first pressing plate and the second pressing plate press both sides of the bound book at the same time, and then, under the action of the first spring, the cutter continues to move downwards to realize trimming the bound book At the same time, after the trimming is completed, the first spring bounces the cutter, and the cutter is separated from the bound book to complete the trimming process of the bound book.
