In some embodiments, the characteristic scraping member 43 may be configured as shown in fig. 7 and 8. Referring to fig. 7 and 8, the scraping member 43 includes a drive screw 431 and a scraper 432.
The axial direction of the drive screw 431 is arranged along the thickness direction of the support plate 41 and is in threaded connection with the support plate 41; specifically, the driving screw 431 penetrates the support plate 41 in the axial direction thereof, and the inner peripheral wall of the penetrating portion of the support plate 41 has an internal thread that is threadedly engaged with the outer periphery of the driving screw 431.
In this embodiment, the end of the driving screw 431 is connected to a second rotating handle 4311, and the driving screw 431 can be adjusted by hand optimally by the second rotating handle 4311, so that the driving screw 431 can be more convenient to be operated manually. The driving screw 431 is provided through the guide hole 311, and a protector surrounding the outer periphery of the driving screw 431 is connected to one side of the support plate 41 facing the distance adjustment plate 31.
The scraper 432 is rotationally connected with the driving screw 431, and the rotational axial direction of the scraper is parallel to the axial direction of the driving screw 431; the blade 432 is used to contact the steel strip 100, and the contact surface is the blade surface.
When the driving screw 431 is screwed in its own axial direction, the driving screw 431 moves the scraper 432.
Wherein, the support plate 41 is provided with a rotation limiting member 44, and the rotation limiting member 44 is used for connecting with the scraper 432 to limit the scraper 432 to rotate relative to the driving screw 431.
By adopting the technical scheme, the driving screw 431 is matched with the scraper 432, so that the scraper 432 is ensured not to rotate, and the stability of the device in actual use is improved.
In some embodiments, the feature rotation limiting member 44 may be configured as shown in fig. 7 and 8. Referring to fig. 7 and 8, the rotation restricting member 44 includes a rotation restricting plate 441 and a positioning screw 442.
The rotation limiting plate 441 is hinged to the support plate 41, and is disposed in the up-down direction in the rotational axial direction, and is configured to be in contact with the scraper 432 to limit the scraper 432 from rotating in the axial direction around the drive screw 431.
Specifically, the rotation limiting plate 441 has a first rotation position and a second rotation position, and when the rotation limiting plate 441 is in the first rotation position, the rotation limiting plate 441 is connected with the scraper 432, so as to limit the rotation of the scraper 432; when the rotation limiting plate 441 is in the second rotation position, the rotation limiting plate 441 is separated from the squeegee 432, so that maintenance, repair, or replacement of the surface of the squeegee 432 can be performed.
