Abstract

The utility model discloses a tension control system of a photogravure press. The tension control system comprises at least two swing rollers and at least three guide rollers, wherein the two swing rollers are simultaneously driven by the same swing arm, and the guide rollers are sequentially arrayed. A thin film material sequentially passes through the guide rollers and the swing rollers as required. After the structure of each swing roller is transformed, double-tension control can be achieved by flexibly changing the material film moving mode according to the tension requirements of the thin film material in the actual printing production According to the transforming scheme, influences on other parts of gravure equipment is little, and accuracy of the gravure equipment can not be influenced.

Description

A kind of intaglio press tension control system

Technical field

The utility model relates to printer field, is specifically related to a kind of intaglio press tension control system.

Background technology

Gravure is the major way of China's flexible packaging printing; and the standard tension range of gravure equipment tension control system can have some limitations conventionally; generally can meet the tension force requirement of the thin-film materials such as BOPP, PET; but the thin-film material for easy stretcher strains such as PE; in print production, just likely cannot stablize control tension force; thereby cause the increase of percent defective, affect the performance of enterprises.

Summary of the invention

The technical problems to be solved in the utility model is to provide a kind of intaglio press tension control system, after pendulum roll structure is transformed, in actual print is produced, just can be according to the tension force requirement of thin-film material, change material film is walked material mode and can be realized the control of double sheet power flexibly.

This modification scheme is minimum on the impact at other positions of gravure equipment, nor can have influence on gravure equipment precision.

For achieving the above object, the technical solution of the utility model is as follows:

A tension control system, comprising:

At least two pendulum rollers, described two same swing arm driving that pendulum roller is controlled by pneumatic control system,

And at least three guide rollers, described guide roller is arranged in turn,

Also comprise a let off roll, thin-film material is successively by being connected with let off roll after guide roller, pendulum roller.

Preferably, pendulum roller be all arranged at guide roller one side, and first pendulum roller be arranged between the second guide roller and the 3rd guide roller, second pendulum roller is arranged between the 3rd guide roller and let off roll.

Preferably, the diameter of described pendulum roller and guide roller is consistent.

By technique scheme, the beneficial effects of the utility model are:

After to pendulum, roll structure transforms, in actual print is produced, just can be according to the tension force requirement of thin-film material, change flexibly material film and walk material mode and can realize the control of double sheet power.

Accompanying drawing explanation

In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.

Fig. 1 is structural representation of the present utility model.

The specific embodiment

For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.

With reference to Fig. 1, a kind of intaglio press tension control system, comprises 2

pendulum rollers

1,2,

pendulum roller

1,2 is setting up and down, share a swing arm 3, and swing arm 3 is fixed in the same swing arm of being controlled by pneumatic control system 9, what be connected with 2 pendulum rollers has each

guide roller

5,6,7.

Pendulum roller

1,2 be all arranged at

guide roller

5,6,7 one sides, and first pendulum roller 2 be arranged between the second guide roller 6 and the 3rd guide roller 5, second pendulum roller 1 is arranged between the 3rd guide roller 5 and let off roll 4.

The diameter of all pendulum rollers and guide roller is consistent.

When needs standard tension range, material film 8 is walked around the first guide roller 7, the second guide roller 6, the first pendulum roller and the 3rd guide roller 5 successively;

When needs low-tension scope, expect that film 8 is walked around the first guide roller 7 successively, the second guide roller 6, first is put roller 2, the 3rd guide roller 5, the second pendulum roller 1 and let off roll 4.

During work, the instruction of blowing tension force is sent, let off roll 4 actions that connected by magnetic controller 10, and pneumatic control system 9 is controlled swing arm 3 actions

Comparison with standard tension force walk material mode, low-tension material film walks to expect that route walks around guide roller twice more, according to principle of moment balance, makes the tension force of expecting film be reduced half, as can be seen here, the double sheet power of pendulum roller is controlled modification scheme and is had exploitativeness.

In actual print is produced, just can be according to the tension force requirement of thin-film material, change material film is walked material mode and can be realized the control of double sheet power flexibly, and the tension force that can meet multiple material is controlled requirement.This modification scheme is minimum on the impact at other positions of gravure equipment, nor can have influence on gravure equipment precision.

More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and description, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
