Further, the spacing portion includes the first bulge that is located on the axle sleeve lock face and is located the second bulge on the axle sleeve lock face down, wherein, forms first draw-in groove between first bulge and the axle sleeve lock face down, forms the second draw-in groove between second bulge and the axle sleeve lock face down, and when last axle sleeve and axle sleeve along axial mutual card down, in the second draw-in groove was located to first bulge card, the second bulge card was located in the first draw-in groove.
The beneficial effects of the utility model are as follows:
1. according to the press roller structure with the adjustable roller spacing, the plurality of the adjusting shaft sleeves are arranged on the central shaft, the adjusting shaft sleeves are provided with different widths, and the positions of the press rollers on the central shaft are changed by changing the adjusting shaft sleeves with different widths.
2. The adjusting shaft sleeve consists of an upper shaft sleeve and a lower shaft sleeve, limiting parts which are mutually clamped along the axial direction are arranged on the buckling surfaces of the upper shaft sleeve and the lower shaft sleeve, the upper shaft sleeve and the lower shaft sleeve can form a complete annular shaft sleeve after being axially buckled through the limiting parts, the adjusting shaft sleeve can be replaced without being taken down from the central shaft, and the process is simple, convenient and practical.

Detailed Description
In order to make the technical purpose, technical scheme and beneficial effect of the present utility model more clear, the technical scheme of the present utility model is further described below with reference to the accompanying drawings and specific embodiments.
Example 1: the utility model provides a roller interval adjustable compression roller structure, as shown in fig. 1-4, includes center pin 1 and cover and locate the epaxial compression roller 2 of center, still includes a plurality of adjusting axle sleeve 3 of cover on center pin 1, and the width of adjusting axle sleeve 3 has multiple width. The distance between the press rollers and the position of the press roller 2 on the central shaft 1 are adjusted by selecting the adjusting shaft sleeve with proper width, so that the requirements of different specifications of door frames on the position of the press roller during bending are met.
Wherein, adjust axle sleeve 3 is including being semi-annular last axle sleeve 31 and lower axle sleeve 32, go up the axle sleeve, form complete cyclic annular axle sleeve after the lower axle sleeve lock in opposite directions, in this embodiment, be provided with along the spacing portion of axial mutual block on the lock face of last axle sleeve 31, lower axle sleeve 32, concretely, spacing portion is including being located the first bulge 7 on the lock face of last axle sleeve 31 and being located the second bulge 9 on the lock face of lower axle sleeve 32, wherein, form first draw-in groove 8 between first bulge 7 and the lock face of last axle sleeve 31, form second draw-in groove 10 between second bulge 9 and the lock face of lower axle sleeve 32, when last axle sleeve 31 and lower axle sleeve 32 follow axial mutual block, first bulge 7 card is located in the second draw-in groove 10, second bulge 9 card is located in the first draw-in groove 8.
