Similarly, the screw spindle 24 is rotated anticlockwise by a wrench for a certain angle, and the spindle adjusting nut 31 on the screw spindle 24 moves inwards to drive the rear sliding seat cover 17 to slide inwards on the rear fixing arm 4 for a certain distance. The screw spindle 24 transmits power to the screw auxiliary shaft 27 through the driving adjusting chain wheel 25, the chain 26 and the driven adjusting chain wheel 28; the screw auxiliary shaft 27 rotates clockwise by the same angle to drive the auxiliary shaft adjusting nut 32 arranged on the screw auxiliary shaft to move inwards, and finally drives the front sliding seat sleeve 23 to slide inwards for a certain distance on the front fixed arm 22. The front sliding seat cover 23 and the rear sliding seat cover 17 together drive the outer mounting plate 18 to slide inwards for a certain distance. Thereby ultimately reducing the distance between the outer conveyor assembly 9 relative to the inner conveyor assembly 8. Finally, the short paper box products are conveyed and run on the outer conveying assembly 9 and the inner conveying assembly 8.
Since the spline main shaft 7 and the spline auxiliary shaft 13 are connected to the outer mounting plate 18 through the outer main shaft spline housing 11 and the auxiliary shaft spline housing 12. The reciprocating movement of the outer mounting plate 18 does not affect the rotational movement of the spline primary shaft 7 and the spline secondary shaft 13.
The above embodiments are provided for illustrating the present invention and not for limiting the present invention, and various changes and modifications may be made by one skilled in the relevant art without departing from the spirit and scope of the present invention, and thus all equivalent technical solutions should be defined by the claims.
