Wherein, rotate supporting component and include support 6 and support 4, support 4 rotate and install in support 6, and doctor blade 5 is fixed to be placed on support 4, and support 6 then can fixed connection in the frame of roll-in equipment to fix whole scraper device. The angle detecting assembly includes an angle sensor 2 for detecting whether the rotation angle of the holder 4 with respect to the frame is a preset angle, that is, an angle by which the doctor blade 5 rotates from an initial position after being installed in place to contact with the press roller to be cleaned, thereby detecting whether the doctor blade 5 is deviated during cleaning of the roll surface. In this embodiment, the scraper device further includes a display device such as a display, a mobile operation end, and the angle sensor 2 is in communication connection with the display device such as the display and the mobile operation end, and the display device can display a detection value of the angle sensor 2, so that an installer or an operator can conveniently judge the scraper device.

Specifically, as shown in fig. 1, in the present embodiment, the rotation support assembly further includes a connection shaft 8 rotatably connected to the bracket 6, the connection shaft 8 being fixedly rotatably disposed at an angle, and the stand 4 is mounted to the connection shaft 8 and is capable of rotating following the connection shaft 8.

In the present embodiment, the angle sensor 2 includes a gyro sensor that is mounted to the connection shaft 8 and is capable of rotating following the connection shaft 8, so that when the rotation angle of the doctor blade 5 is adjusted by rotating the connection shaft 8, the current rotation angle of the doctor blade 5 is indirectly measured by measuring the rotation angular velocity of the connection shaft 8. Of course, in some other embodiments, the angle sensor 2 may also be mounted to the support 4 and rotate with the support 4, and also be able to detect the current rotation angle of the doctor blade 5.
Of course, in some specific embodiments, other sensors such as hall sensors, photoelectric sensors, magneto-electric sensors, etc. may be used to measure the rotation angle of the connecting shaft 8 or the support 4 relative to other fixed references such as the roll surface, the frame, etc. to obtain the current angle of the doctor blade 5, or directly measure the current angle of the doctor blade 5, which is not specifically limited in the present utility model, so long as the current angle of the doctor blade 5 can be obtained.
Alternatively, in the present embodiment, the connecting shaft 8 is provided with at least two angle sensors 2, and the support 4 is located between the two angle sensors 2. The two angle sensors 2 can measure the rotation angle of the doctor blade 5, so that an installer or an operator can conveniently judge whether the doctor blade 5 is bent or distorted according to the detection values of the two angle sensors 2.
Specifically, the support 4 has a mounting groove in which the doctor blade 5 is inserted, one side wall of the mounting groove is provided with at least two mounting holes, each of which is connected with a pressing member that abuts against a side surface of the doctor blade 5, thereby fixing the doctor blade 5 in the support 4.

In this embodiment, the angle scale 7 includes a plurality of scale marks, and the extending direction of a plurality of scale marks all passes through the axis of connecting axle 8, and a plurality of scale marks include 0 degree scale mark and 90 degree scale mark, and 0 degree scale mark sets up along the horizontal direction, and 90 degree scale mark sets up along vertical direction, and is provided with a scale mark every 5 between 0 degree scale mark and the 90 degree scale mark, and angle guide needle 3 rotates between 0 degree scale mark and 90 degree scale mark with the intersection point position of 0 degree scale mark and 90 degree scale mark as the center. Of course, the common rotation angle can be set as the scale marks in the manner shown in fig. 2, so that the calibration flow of the rotation angle is simplified.
When judging, for example, the operator can easily judge the current rotation angle of the doctor blade 5 by extending the line of sight from the doctor blade 5 to the angle guide pin 3 to the angle scale 7 along the axial direction of the connecting shaft 8. When the angle sensor 2 fails or is abnormal, for example, the detection value of the angle sensor 2 is smaller than 45 °, and the scale line pointed by the angle guiding needle 3 is between the 0 ° scale line and the 45 ° scale line, the abnormality of the angle sensor 2 can be determined. And when the abnormity is eliminated, the angle scale 7 and the angle guide needle 3 can provide references for debugging, replacement or zeroing of the angle sensor 2, and can provide another way for determining the current angle of the scraper blade 5 when display equipment such as a display is abnormal, so that redundant design is realized, and the use experience of the scraper device is further optimized.

Alternatively, in some other embodiments, the angle guiding pins 3 may be disposed at two ends of the support 4, and the specific disposition position of the angle guiding pins 3 is not limited in the present utility model, so long as it can assist in determining whether the doctor blade 5 is bent or twisted.
