Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

Referring to fig. 1-5, an anticorrosion version roller subassembly, include roll body 1 and run through along roll body 1 central line roll body 1's center pin 2, it has rather than rotating the regulation pole 22 of being connected to peg graft in 2 center pins, still includes two stoppers 21 that the symmetry set up, stopper 21 runs through center pin 2 and joint are in the draw-in groove 11 of roll body 1 inner wall, still the cover is equipped with spring 23 on the stopper 21, adjusts pole 22 through rotating and can make stopper 21 joint in draw-in groove 11 or

income center pin

2, 2 both ends of center pin still are provided with and are used for restricting the spacing subassembly of regulation pole 22 pivoted, spacing subassembly with the center pin 2 can be dismantled and be connected.

This application is through setting up stopper 21 in center pin 2 to adjust the position of stopper 21 through adjusting pole 22, specifically, adjust the cross section of pole 22 and be oval or other non-circular structure. When needing to fix center pin 2 and roll body 1, the long limit that will adjust pole 22 is rotatory to stopper 21 department, it pushes up stopper 21 to draw-in groove 11 to adjust pole 22, thereby reach center pin 2 and roll body 1's fixed, when needs are unpacked center pin 2 and roll body 1 apart, only need to adjust the minor face rotation of pole 22 to stopper 21 department, stopper 21 contracts to the center pin 2 under spring 23's effect this moment in, can extract center pin 2 from roll body 1 this moment, and is simple and convenient.

Specifically, spacing subassembly is including pegging graft the control tube 3 at the both ends of center pin 2, control tube 3 with the one end parallel arrangement that center pin 2 is connected has two first fixture blocks 31 and two second fixture blocks 32, and two first fixture blocks 31 peg graft in center pin 2 and lie in the both sides of adjusting pole 22 for the rotation of restriction regulation pole 22, second fixture block 32 distributes in the spacing groove 24 of 2 lateral walls of center pin, is used for restricting the rotation of control tube 3, still including the cover establish the fixed cover 33 in the control tube 3 outside, fixed cover 33 with control tube 3 sliding connection, fixed cover 33 with 2 lateral wall threaded connection of center pin.

The limiting assembly comprises a first clamping block 31 and a second clamping block 32 which are matched with each other to limit rotation of the adjusting rod 22, so that stability of the plate roller assembly in the using process is guaranteed, and printing accuracy of the plate roller assembly is improved. The fixed sleeve 33 and the adjusting pipe 3 can also rotate mutually, the adjusting pipe 3 and the central shaft 2 can be fixed through the threaded connection relation of the fixed sleeve 33 and the central shaft 2, and in addition, the fixing can be carried out in a clamping hoop mode.
