The mirror reflection type photoelectric sensor 21 is in signal connection with the control processing unit. The reflection prism 22 can resist high temperature and high humidity, and the infrared beam emitted by the mirror reflection type photoelectric sensor 21 has the characteristic of high concentration, and the mirror surface of the mirror reflection type photoelectric sensor 21 has a heating function. Therefore, the mirror reflection type photoelectric sensor assembly 20 is suitable for being installed at a processing station with high temperature and high humidity of the paper machine 10, and the emission and the reception of the infrared light beams are not affected by water vapor interference, so that the problems of misjudgment, failure and the like are avoided.
The diffuse reflection type photoelectric sensor assembly 30 includes two diffuse reflection type photoelectric sensors 31 disposed opposite to each other, and the two diffuse reflection type photoelectric sensors 31 are respectively disposed on the operation side and the transmission side of the transmission roller 11. Both of the diffuse reflection type photoelectric sensors 31 are in signal connection with the control processing unit. The infrared beam emitted by the diffuse reflection type photoelectric sensor 31 is reflected by the paper web, and whether the paper is broken is judged by using the intensity of the infrared light reflected by the paper web, so that the diffuse reflection type photoelectric sensor 31 is more suitable for the processing station of the paper machine 10 with normal temperature and low humidity. The diffuse reflection type photoelectric sensors 31 are arranged in pairs, and only when both the diffuse reflection type photoelectric sensors 31 detect a paper breaking signal, the control processing unit can judge that the paper breaking is abnormal. Therefore, the detection accuracy can be improved, and the problems of misjudgment and failure caused by the influence of the phenomena of paper web jitter and the like on the signal reception of the infrared light beam are reduced.
The suction roll unit 40 comprises a pressure introduction roll 41, a suction roll 42, a felt 43, a bottom wire (not shown), two press rolls 44 and a bottom couch roll (not shown). The two press rolls 44 are disposed opposite to each other, the one pressure introducing roll 41 and the suction roll 42 are also disposed opposite to each other, and one end of the felt 43 is sandwiched between the two press rolls 44 and the other end is sandwiched between the one pressure introducing roll 41 and the suction roll 42. The two bottom net couch rolls are arranged at intervals, the bottom nets are sleeved on the two bottom net couch rolls, and the bottom nets are in contact with the felt 43. When a paper break is detected in the pre-drying section of the machine 10, the control and processing unit may control the suction roll 42 to lift in time to allow the web to fall into the wet-loss pulper without passing through the press section and the drying section to clog the felt 43 or the dryer fabric.
The banner cutter 50 includes a fixing frame 51, a cylinder 52, a rotary blade holder 53 and a blade 54.

The air cylinder 52 is also in signal connection with the control processing unit. When detecting that the post-drying, calendering, coating and other parts of the paper machine 10 are broken, the control processing unit can control the cylinder 52 to extend so as to drive the rotary tool holder 53 to rotate downwards, and the rotary tool holder 53 rotating downwards further enables the blade 54 to press downwards to break the paper web, so that the situation that the paper web at the front section is continuously transmitted to block the rear section station is avoided.
The utility model discloses during the operation, at first by the specular reflection formula photoelectric sensor 21 and the diffuse reflection formula photoelectric sensor 31 transmission infrared light beam of paper machine 10 each department installation detect the paper web. The mirror reflection type photoelectric sensor 21 can reflect the emitted infrared light beams to a receiver through the reflection prism 22 when the paper web breaks, and the receiver sends out a paper breaking signal to the control processing unit when receiving the infrared light beams. When the paper web breaks, the diffuse reflection type photoelectric sensor 31 changes the intensity of the infrared light beam reflected by the paper web and received by the receiver originally, and then the sensor sends a paper breaking signal to the control processing unit. And the paired diffuse reflection type photoelectric sensors 31 carry out double detection from two sides of the paper web, and the control processing unit can judge the paper breaking abnormity only after the two diffuse reflection type photoelectric sensors 31 send paper breaking signals to the control processing unit.
When the control processing unit judges that the paper web on the paper machine 10 has paper breaking abnormality, different processing is performed according to different paper breaking positions. If paper break occurs in the pre-drying part, the control processing unit sends a signal to the suction roller device 40 to control the suction roller 42 to lift, so that the web paper stops transmitting to the subsequent station and falls into the wet-damage pulper for recycling. And if the post-drying, calendaring, coating and other parts break paper, the control processing unit sends a signal to control the transverse paper cutting knife 50 at the paper feeding side of the paper breaking part to cut off the paper web in time, so as to avoid the blockage of the paper machine 10 caused by the driving of the driving roller 11 on the broken paper web.
To sum up, the utility model relates to a paper machine 10 breaks paper and detects interlock's beneficial effect lies in: the control processing unit and a plurality of groups of photoelectric sensor assemblies are arranged on the paper machine 10 to monitor the running state of the paper web in real time on line, so that the paper machine 10 can detect the abnormal problem of paper breaking in time in the high-speed running process, and the running reliability of the paper machine 10 is greatly improved; meanwhile, the paper machine 10 is also provided with a suction roller device 40 and a plurality of groups of cross-web paper cutting blades 50 which are automatically controlled by the control processing unit, so that when the paper machine 10 is detected to have abnormal paper cutting, the paper web can be quickly cut, the paper web is prevented from being accumulated and jammed, and the maintenance cost of the paper machine 10 for abnormal paper cutting is greatly reduced; the utility model discloses the practicality is strong, has stronger popularization meaning.
