Detailed Description
The utility model relates to a detection device of drawing frame roller rotational speed comprises magnetic induction rotary encoder 1 and installing support 2, and it is right to combine the attached drawing below the utility model discloses an embodiment further describes.
As shown in fig. 1, the mounting bracket 2 includes a base 3, a longitudinal adjustment lever 4, a lateral adjustment lever 5, and a distance adjustment lever 6. The base 3 is preferably a permanent magnetic chuck, so that the permanent magnetic chuck is conveniently fixed and adsorbed on the drawing frame. The longitudinal adjusting rod 4 is cylindrical and is vertically fixed on the base 3. A double-ring lock catch 7 is arranged between the transverse adjusting rod 5 and the longitudinal adjusting rod 4 and used for connecting and fixing the transverse adjusting rod 5 and the longitudinal adjusting rod 4. A locking handle 8 with a screw is arranged between the transverse adjusting rod 5 and the distance adjusting rod 6 for connecting and fixing the transverse adjusting rod 5 and the distance adjusting rod 6.
In order to achieve a flexible adjustment of the longitudinal adjustment bar 4 and the transverse adjustment bar 5, a double loop locking design is used in this embodiment.
