The connecting short rod 1 27 drives the rotating gear 18 to rotate. The rotating gear 18 drives the gear ring 15 and the rubber cleaning ring 17 to rotate. When the prestressed concrete steel bundle protective sleeve appears from the feeding port, the rotating rubber cleaning ring 17 will clean the surface of the prestressed concrete steel bundle protective sleeve. When the two supporting rollers 31 support the prestressed concrete steel bundle protective sleeve, due to the damping shaft 28, the supporting rollers 31 will resist the prestressed concrete steel bundle protective sleeve and will no longer move. The rotation of the rubber cleaning ring 17 will not be disturbed. While ensuring the stability of the protective sleeve during cutting, impurities on its surface can also be efficiently cleaned.

[0057] The embodiments of the present invention are given for the purpose of illustration and description, and are not intended to be exhaustive or to limit the invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.
