The utility model relates to metal wire rod processing equipment technical field, concretely is a kind of micro fine wire drawing machine with guide wheel slag-removing mechanism, including mounting plate, the outer surface of mounting plate is fixedly connected with several mounting seat, the outer surface of mounting plate is fixedly connected with mounting bracket, the side of mounting bracket away from mounting plate is fixedly connected with movable disc by bolt, the side of movable disc away from mounting bracket is fixedly connected with mounting shaft, the outer wall of mounting shaft is rotatably connected with guide wheel main part, the outer surface of mounting plate is fixedly connected with slag-removing adjusting assembly;Beneficial effect is that: the utility model is by adopting the meshing structure of worm and half worm wheel, the angular rotation movement in the circumferential direction of movable seat can be realized by rotating carousel, and the position and angle of slag-removing motor and cleaning brush are conveniently adjusted, the slag-removing intensity and angle can be flexibly adjusted according to the actual use condition and impurity adhesion degree of guide wheel, ensure that cleaning brush can timely, effectively brush off the impurity on the surface of guide wheel main part.

This application provides a table entry management method and apparatus, relating to the field of communication technology and applied to network devices. The method includes: setting a hardware MAC address table to prevent aging; executing a software table entry polling task to poll each storage location of the software MAC address table; the software table entry polling task performing a logical AND operation between the authentication type of the first software MAC address table entry at the polled storage location and an aging filter bitmap mask; wherein the aging filter parameter bit of the aging filter bitmap mask is set to a binary value of 1; determining that the corresponding bit of the aging filter parameter bit in the logical AND operation result has a binary value of 1, identifying that the first software MAC address table entry matches the aging filter parameter; and polling the next storage location of the software MAC address table to skip the aging deletion process of the first software MAC address table entry. This solution can solve the problem of user terminals being online, but hardware MAC address table entries being aged, thus improving the user's internet experience.
