Abstract

The utility model relates to an intaglio printing production line which comprises a paper holding device, an intaglio printing device, a transverse cutting device and a paper collecting device which are arranged in sequence. The paper output position of the paper holding device corresponds to the paper input position of the intaglio printing device; the paper output position of the intaglio printing device corresponds to the paper input position of the transverse cutting device; the paper output position of the transverse cutting device corresponds to the paper input position of the paper collecting device; and the intaglio printing production line is characterized in that the circumference of the transverse cutting knife roll of the transverse cutting device is larger than that of the printing plate of the intaglio printing device, therefore, during the process of the operating of the intaglio printing production line, printing paper is in a tensioning state, the tensile force of theprinting paper is constant, therefore, fluctuation can not occur during the printing process, the fluctuation of a transverse cutting front lay can not occur too during the transverse cutting process,the transverse cutting of the printing paper becomes very accurate, and the subsequent working procedures are convenient to be performed; simultaneously, as the tensile force of the printing paper isconstant, the phenomenon of the movement of the print paper can not occur during the transverse cutting process, the continuous production can be ensured, and the production efficiency is improved.

Description

A kind of gravure production line

Technical field

The utility model relates to a kind of printing equipment, more particularly, relates to a kind of gravure production line.

Background technology

Existing gravure production line generally comprise set gradually put paper apparatus, gravure device, infeed set-up, delivery device, above-mentioned paper output place of putting paper apparatus is corresponding with the paper input of gravure device, paper output place of gravure device is corresponding with the paper input of infeed set-up, and paper output place of infeed set-up is corresponding with the paper input of delivery device.

Above-mentioned paper apparatus, gravure device and the delivery device put is prior art, just is not described in any further at this.

In the design of existing gravure production line, the girth of crosscut rotor equals the girth of galley in the gravure device in the infeed set-up, for example, in traditional gravure Design of Production Line, when the girth of galley is 506mm, the girth of crosscut rotor also is 506mm, like this, in the course of work of gravure production line, the tension force instability of printing sheets, cause that easily printing sheets is loosening, cause printing fluctuation, and the printing fluctuation is advised fluctuation before can causing crosscut, makes the crosscut of printing sheets inaccurate, this just can bring very big workload to subsequent handling, thereby can't in time finish production task.

Simultaneously, because the tension force instability of printing sheets, so, in the crosscut process also the phenomenon that printing sheets is run can take place, just have a printing sheets behind several printing sheets of crosscut and jump up, thereby production can't be carried out continuously, reduced production efficiency.

This shows that in the course of work of gravure production line, the control of the tension force of printing sheets is very crucial,, become a technical problem of being badly in need of solution for printing sheets provides a constant tension force.

Summary of the invention

The technical problems to be solved in the utility model provides the gravure production line that a kind of crosscut is accurate, production efficiency is high.

In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is as follows:

A kind of gravure production line, comprise set gradually put paper apparatus, gravure device, infeed set-up, delivery device, above-mentioned paper output place of putting paper apparatus is corresponding with the paper input of gravure device, paper output place of gravure device is corresponding with the paper input of infeed set-up, and paper output place of infeed set-up is corresponding with the paper input of delivery device; It is characterized in that: the girth of crosscut rotor is greater than the girth of galley in the gravure device in the above-mentioned infeed set-up.

Because the girth of crosscut rotor is greater than the girth of galley in the gravure device in the infeed set-up, so, in the course of work of gravure production line, printing sheets is in tensioning state, and the constant tension of printing sheets, therefore, can not fluctuate in the printing process, rule were not fluctuateed before crosscut also can not take place in the crosscut process, thereby made the crosscut of printing sheets become very accurate, were convenient to the carrying out of subsequent handling; Simultaneously, because the tension stability of printing sheets, so, the phenomenon that printing sheets is run can not take place, thereby production can be carried out continuously in the crosscut process, improved production efficiency.

As preferred structure of the present utility model, the girth of described crosscut rotor is than the Zhou Changda 0.2mm～0.3mm of galley.

For example, when the girth of galley was 506mm, the girth of crosscut rotor can be got value: a 506.2mm～506.3mm appointing in the following ranges value.

The utility model beneficial effect against existing technologies is, because the girth of crosscut rotor is greater than the girth of galley in the gravure device in the infeed set-up, so in the course of work of gravure production line, printing sheets is in tensioning state, and the constant tension of printing sheets, therefore, can not fluctuate in the printing process, can not take place in the crosscut process to advise fluctuation before the crosscut yet, it is very accurate that thereby the crosscut that makes printing sheets becomes, and is convenient to the carrying out of subsequent handling; Simultaneously, because the tension stability of printing sheets, so, the phenomenon that printing sheets is run can not take place, thereby production can be carried out continuously in the crosscut process, improved production efficiency.

Below in conjunction with the drawings and specific embodiments the utility model is described further.
