Description

Paper tension control device in printing process

Technical Field

The utility model relates to a paper tension controlgear field especially relates to a printing in-process paper tension controlling means.

Background

In the process of unwinding rolls on a production line of a printing machine for paper processing, the paper to be used is under tension or stress. This tension needs to be controlled because there is mechanical force to stretch, stretch or pull the web. Too little tension makes register control more difficult and too much tension can cause sheet distortion.

The existing tension control device has simple structure, the additional tension generated without automatic control function is a preset constant tension compensation value, and the additional tension is not changed due to the change of the unwinding tension of the yarn, so that the winding tension actually running after the unwinding tension and the additional tension are superposed inevitably fluctuates, which can cause winding unevenness and fluctuation of the yarn tension during unwinding in a downstream process. The paper tension adjustment effect is not good.

SUMMERY OF THE UTILITY MODEL

The utility model discloses the technical problem that the effect is not good is adjusted to main tension controlling means paper tension of solving prior art provides a printing in-process paper tension controlling means to reach the purpose that improves the paper at the tensile stability of printing in-process.

The utility model provides a printing in-process paper tension control device, include: the device comprises a swing arm roller 1, a bearing shaft 2, a cylinder 6, a cylinder fixing frame 5, a gear 8 and a potentiometer 9;

the bearing shaft 2 is arranged on the inner wall of the printing machine through a bearing bush seat 11;

two ends of the bearing shaft 2 are respectively welded with bearing shaft arms 3; the bottom ends of the two bearing shaft arms (3) are provided with swing arm rollers (1);

the cylinder 6 is arranged on the cylinder fixing frame 5, and a push rod of the cylinder 6 is connected with the bearing shaft arm 3; the cylinder fixing frame 5 is arranged on the inner wall of the printing machine;

the gear 8 is fixed at one end of the bearing shaft 2 and is meshed with a fluted disc 10 of the potentiometer.

Preferably, the lower end of the bearing shaft arm 3 is provided with a bearing opening, a bearing 4 is arranged in the bearing opening, and the bearing 4 bears the rotating shaft of the swing arm roller 1.

Preferably, the cylinder 6 is mounted on the cylinder holder 5 by a connecting shaft 7.

The utility model provides a pair of printing in-process paper tension control device compares with prior art and has following advantage:

1. the utility model discloses machinery combines together with electricity. The whole device is connected with a transmission motor, and the rotating speed of the motor is determined by a frequency converter. The potentiometer outputs an electric signal to the frequency converter, and the frequency converter changes the frequency of the output voltage to change the rotating speed of the motor. The change of the motor rotating speed can change the tightness of the paper in the transmission process, the output is more stable, and therefore the stability of the tension of the paper in the printing process is improved.

2. The method comprises the steps of setting an air cylinder, wherein air pressure adjustment of the air cylinder is realized by manually adjusting an air pressure valve, the air pressure valve of the air cylinder is connected with an air pressure meter, real numbers of the air pressure meter are read while the air pressure valve is adjusted, and an air cylinder adjusting valve is adjusted according to tension required by different paper during production. The utility model discloses a swing of swing arm roller is adjusted to the cylinder, realizes tension control through adjusting atmospheric pressure, controls more easily.

3. The structure is simple and clear, and the maintenance and the repair are easy.

Detailed Description

In order to make the technical problem solved by the present invention, the technical solution adopted by the present invention and the technical effect achieved by the present invention clearer, the present invention will be further described in detail with reference to the accompanying drawings and the embodiments. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some but not all of the relevant portions of the present invention are shown in the drawings.

Fig. 1 is a schematic structural diagram of a paper tension control device in a printing process according to an embodiment of the present invention. As shown in fig. 1, the embodiment of the present invention provides a paper tension control device in printing process, including: swing arm roller 1, bearing shaft 2, cylinder 6, gear 8 and potentiometer 9.

The bearing shaft 2 is mounted on the inner wall of the printing machine through a bearing bush 11.

Two ends of the bearing shaft 2 are respectively welded with bearing shaft arms 3; the bottom ends of the two bearing shaft arms 3 are provided with swing arm rollers 1. Specifically, the lower end of the bearing shaft arm 3 is provided with a bearing opening, a bearing 4 is arranged in the bearing opening, the bearing 4 can bear the rotating shaft of the swing arm roller 1, and the swing arm roller 1 is installed on the bearing shaft arm 3 through the bearing.
