Abstract

The utility model discloses a paper winding mechanism for a novel printer. The paper winding mechanism comprises a machine body wall plate, an unwinding roller, a winding roller and two guide rollers positioned between the unwinding roller and the winding roller, and is characterized by further comprising a programmable controller, a first variable-frequency motor which is connected with the unwinding roller, a second variable-frequency motor which is connected with the winding roller, and a tension measuring roller which is positioned between the two guide rollers; and the tension measuring roller is connected with the first variable-frequency motor and the second variable-frequency motor through the programmable controller respectively. In the paper winding mechanism, a tension detector and the programmable controller which is connected with the first variable-frequency motor and the second variable-frequency motor through the tension detector respectively are arranged, tension at the two ends of the unwinding roller and the winding roller can be detected in real time, and speeds of the first variable-frequency motor and the second variable-frequency motor are adjusted according to a detected signal, so that the relative transmission speed between the unwinding roller and the winding roller is controlled, and the breaking phenomenon of paper in the paper winding mechanism is reduced greatly.

Description

A kind of coil paper mechanism of new type printing press

Technical field

The utility model relates to field of printing machinery, is specifically related to a kind of coil paper structure of new type printing press.

Background technology

The coil paper mechanism of traditional printer in the course of the work, let off roll is constantly put paper, the diameter of let off roll reduces gradually; Wind-up roll is collection constantly, and the diameter of wind-up roll increases gradually, therefore causes the speed of transmission of paper at both ends different; Let off roll one end paper is lax; Wind-up roll one end paper tensioning is because the overbalance of two ends tension force is easy to cause paper to fracture.

In order to solve above-mentioned deficiency of the prior art, the utility model provides a kind of new solution.

The utility model content

The technical matters that the utility model will solve is: the deficiency that is directed to prior art; A kind of coil paper mechanism of new type printing press is provided, and this mechanism can solve owing to the unbalanced paper tensioning that causes of tension force between let off roll and the wind-up roll, lax problem effectively.

For reaching the foregoing invention purpose; The technical scheme that the utility model adopted is: the coil paper mechanism that a kind of new type printing press is provided; Comprise fuselage wallboard, let off roll, wind-up roll, two deflector rolls between let off roll and wind-up roll; It is characterized in that: also comprise Programmable Logic Controller, and let off roll bonded assembly first variable-frequency motor, and wind-up roll bonded assembly second variable-frequency motor, the tonometry roller between two deflector rolls; Said two deflector rolls and tonometry roller are arranged on the fuselage wallboard, and said tonometry roller is connected with second variable-frequency motor with first variable-frequency motor respectively through Programmable Logic Controller.

Said tonometry roller is made up of tonometry device and deflector roll, and said tonometry device is arranged on the fuselage wallboard, and the two ends of the roll shaft of said deflector roll are embedded in the groove of tonometry device, and realization is connected with the tonometry device.

Said Programmable Logic Controller is connected with the interface of tonometry roller through the output line of tonometry device.

In sum; The coil paper mechanism of the new type printing press that the utility model provides through be provided with tension detector and through tension detector respectively with first variable-frequency motor and the second variable-frequency motor bonded assembly Programmable Logic Controller; Can the tension force at let off roll and wind-up roll two ends be detected in real time; And first variable-frequency motor and second variable-frequency motor are carried out speed governing according to detected signal; Thereby control the relative speed of transmission between let off roll and the wind-up roll, significantly reduced the phenomenon that fractures of paper in the coil paper mechanism.
