Description
Technical field
The utility model relates to the printing machine equipment mechanical field, is specifically related to a kind of rotary press paper tape edge slack automatic regulating apparatus.
Background technology
In web press, when roll web rewinding poor quality or paper roll make moist, can there be the edge slack phenomenon, namely the both sides tightness of paper tape is inconsistent.Due to the overall tension force of the web tension that arranges at console when operating for the printing paper tape, such paper tape enters printing element, due to web tension skewness in the horizontal, the slack list can be not enough because of web tension, cause paper tape to swing, the problems such as register trouble, printing ghost image occur, affect the product printing quality; Pilled-in selvedge might be because of the overtension paper tape that snaps.Generally, the place is provided with the manual calibration roller at the paper supply frame, and an end support of aligning roller can swing, and adjusts unbalanced pulling force between paper tape both sides by the position of adjusting aligning roller, makes the both sides level of tightness consistent.But this situation needs the tightness on manual observation paper tape both sides, be difficult for to observe for unconspicuous edge slack, and can not be from the situation of change of motion tracking both sides edge slack.
In order to solve above-mentioned deficiency of the prior art, the utility model proposes a kind of new solution.
The utility model content
The purpose of this utility model is to provide a kind of paper tape edge slack automatic detection and adjustment device, guarantees the balance of paper tape both sides tension force, eliminates the unbalanced tensile force on paper, improves printing quality.
For reaching above-mentioned purpose, the technical scheme that the utility model adopts is: a kind of rotary press paper tape edge slack automatic regulating apparatus is provided, comprises tonometry mechanism, pressure sensing module and correcting mechanism, correcting mechanism is arranged on the paper supply frame; Tonometry mechanism comprises support and tonometry roller, and the tonometry roller is fixed on support; Correcting mechanism comprises aligning roller and eccentric wheel, and eccentric wheel is by driven by servomotor; The pressure sensing module comprises pressure sensor, signal amplifier and central controller; Pressure sensor is arranged on tonometry roller both sides, signal amplifier Bonding pressure sensor and central controller; Central controller is connected with servomotor.
Preferably, described pressure sensor comprises the pressure-sensitive strain-gage pickup of transmission side and the pressure-sensitive strain-gage pickup of fore side.
Preferably, described aligning roller both sides are provided with the adjusting center bearing, one of them adjusting center bearing connecting eccentric wheel and aligning roller.
Preferably, described servomotor is provided with motor worm, and motor worm drives the eccentric wheel tooth bar, eccentric wheel tooth bar and eccentric wheel engagement.
In sum, the utility model advantage: the pressure sensor by tonometry roller two ends is monitored the pressure of paper tape both sides, and in time monitor signal is exported, regulate aligning roller, follow the tracks of at any time and adjust trimming, both sides degree of tightness situation, make web tension more stable, guarantee printing quality.

The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in detail.
As shown in Figures 1 to 4, the utility model is a kind of rotary press paper tape edge slack automatic regulating apparatus, comprises tonometry mechanism, pressure sensing module and correcting mechanism, and correcting mechanism is arranged on the paper supply frame; Tonometry mechanism comprises support 1 and tonometry roller 2, and tonometry roller 2 is fixed on support 1; Correcting mechanism comprises aligning roller 3 and eccentric wheel 4, and eccentric wheel 4 is driven by servomotor 5; The pressure sensing module comprises pressure sensor, signal amplifier 8 and central controller 9; Pressure sensor is arranged on tonometry roller 2 both sides, signal amplifier 8 Bonding pressure sensors and central controller 9; Central controller 9 is connected with servomotor 5.
To the paper road of printing element, a tonometry roller 2 is installed at the paper supply frame, on 2 liang of side stands 1 of tonometry roller, pressure sensor is installed, be used for measuring the suffered paper tape pulling force of two side stands 1.In operation in the middle of tonometry roller 2, when web tension was evenly distributed in the horizontal, the value of feedback of pressure at both sides sensor equated due to paper tape; When the slack list appearred in a side, the value of feedback of the pressure sensor of this side just reduced.In the situation that overall web tension is constant, the pressure sensor value of feedback of pilled-in selvedge just raises, and can measure the paper tape distribution situation of tension force in a lateral direction with pressure sensor like this.At the paper supply frame, aligning roller 3 is set, two side bearings are adjusting center bearing 10, wherein the adjusting center bearing 10 of a side is arranged on an eccentric wheel 4, eccentric wheel 4 is driven by servomotor 5, can change the position of eccentric wheel 4, be used for adjusting the unbalanced web tension in paper tape both sides, make trimming, both sides level of tightness consistent.
Preferably, described pressure sensor comprises the pressure-sensitive strain-gage pickup 6 of transmission side and the pressure-sensitive strain-gage pickup 7 of fore side.
Preferably, described aligning roller 3 both sides are provided with adjusting center bearing 10, one of them adjusting center bearing 10 connecting eccentric wheels 4 and aligning roller 3.
Preferably, described servomotor 5 is provided with motor worm 11, and motor worm 11 drives eccentric wheel tooth bar 12, eccentric wheel tooth bar 12 and eccentric wheel 4 engagements.
Although by reference to the accompanying drawings the specific embodiment of the present utility model is described in detail, should not be construed as the restriction to the protection domain of this patent.In the described scope of claims, the various modifications that those skilled in the art can make without creative work and distortion still belong to the protection domain of this patent.
