Description

A kind of anti-bias dancing roll of zero-speed splicer

Technical field

This utility model relates to a kind of splicer dancing roll, especially relates to a kind of anti-local derviation paper of zero-speed splicer Roller.

Background technology

At present, automatic splicer matching used with roll-fed offset printing press (paper frame), predominantly zero-speed automatic splicer, it Be all in the case of offset press normally prints, be automatically performed splicing action.Zero-speed automatic splicer is provided with a storage Paper storehouse parts, this parts Main Function be when the paper of a roll web on splicer run low want splicing time, transporting This roll web turned stops, and another new roll web connects and rotate this mistake of normal print speed printing speed reaching offset press automatically Cheng Zhong, needs to save a certain amount of standby paper for offset press normally, and these storage paper storehouse parts are mainly led paper by a row is fixing Roller and row's activity dancing roll composition, paper is wrapped between fixing dancing roll and movable dancing roll, when movable dancing roll rises Time, increase with the spacing of fixing dancing roll, store paper amount and be increased by, otherwise, just reduce.The dancing roll of prior art is positive cylinder Body, paper easily offsets dancing roll center during transmitting, thus affects follow-up printing process；Secondly, dancing roll surface The most smooth, when roll web changed by needs, when i.e. movable dancing roll moves, especially lead near fixing at movable dancing roll When paper bowl moves, paper is susceptible to the phenomenons such as landing.

Utility model content

The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, it is provided that a kind of simple in construction, can have Effect prevents paper from offseting the anti-bias dancing roll of zero-speed splicer at dancing roll center in moving process.

This utility model solves its technical problem and be the technical scheme is that a kind of anti-local derviation paper of zero-speed splicer Roller, including cylindrical roller body and anti-deflection device；Described anti-deflection device symmetry is set in cylindrical roller body two ends, and can be along cylindrical Roll body moves left and right, and i.e. moves along cylindrical roller body central axial direction.

Further, described anti-deflection device is a hollow cylinder；The external diameter of one end of described cylinder is slightly larger than circle The external diameter of cylindricality roll body, its external diameter is gradually increased to the other end by one end, and is smoothly connected.

Further, described cylinder outer surface is curved, and the radius of curvature of described arc is 200 ~ 300cm, preferably 200 ~ 250cm。

Further, the one end side that described anti-deflection device external diameter is little offers hole, location.

Further, described anti-deflection device is by being fixed on cylindrical roller body through the bolt in hole, location.

Further, the end of described cylindrical roller body connects connecting rod.

Further, the interlude of described cylindrical roller body is provided with the antiskid groove of strip.

This utility model a kind of zero-speed splicer operation principle of anti-bias dancing roll and using method: by outside anti-deflection device Little one end, footpath is towards the interlude of cylindrical roller body, and the big one end of external diameter is located at cylindrical roller body towards the end sleeve of cylindrical roller body On.The paper size transmitted according to dancing roll, on regulation cylindrical roller body, the position of anti-deflection device, makes anti-deflection device external diameter little One end between distance is paper width 1.05 ~ 1.10 times.Again with bolt through hole, location, anti-deflection device is fixed On cylindrical roller body.The connecting rod of cylindrical roller body end is easy to zero-speed splicer and is arranged on storage paper with anti-bias dancing roll On the support of storehouse.By the anti-slip tank of cylindrical roller body interlude, when dancing roll is when mobile, paper landing can be avoided.

This utility model a kind of zero-speed splicer beneficial effect of anti-bias dancing roll: simple in construction；Anti-bias respond well； When dancing roll is when mobile, paper landing can be avoided.

Detailed description of the invention

Below in conjunction with drawings and Examples, the utility model is described in further detail.

Embodiment 1

With reference to Fig. 1 ~ 3, a kind of anti-bias dancing roll of zero-speed splicer, including cylindrical roller body 3 and anti-deflection device 2；Described Anti-deflection device 2 symmetry is set in cylindrical roller body 3 two ends, and can move left and right along cylindrical roller body 3, i.e. along cylindrical roller body 3 Central axial direction moves.

Described anti-deflection device 2 is a hollow cylinder；The external diameter of one end of described cylinder is slightly larger than cylindrical roller The external diameter of body 3, its external diameter is gradually increased to the other end by one end, and is smoothly connected.

Described cylinder outer surface curved 4, the radius of curvature of described arc 4 is 200cm.

Hole 5, location is offered on the one end side that described anti-deflection device 2 external diameter is little.

Described anti-deflection device 2 is by being fixed on cylindrical roller body 3 through the bolt in hole 5, location.

The end of described cylindrical roller body 3 connects connecting rod 1.

Embodiment 2

With reference to Fig. 4 and Fig. 5, a kind of anti-bias dancing roll of zero-speed splicer, including cylindrical roller body 3 and anti-deflection device 2；Institute State anti-deflection device 2 symmetry and be set in cylindrical roller body 3 two ends, and can move left and right along cylindrical roller body 3, i.e. along cylindrical roller body 3 central axial direction move.

Described cylinder outer surface curved 4, the radius of curvature of described arc 4 is 250cm.

The end of described cylindrical roller body 3 connects connecting rod 1.

The interlude of described cylindrical roller body 3 is provided with the antiskid groove 6 of strip, as shown in Figure 5.

This utility model a kind of zero-speed splicer operation principle of anti-bias dancing roll and using method: by anti-deflection device 2 The little one end of external diameter is towards the interlude of cylindrical roller body 3, and the big one end of external diameter is located at cylinder towards the end sleeve of cylindrical roller body 3 On roll body 3.The paper size transmitted according to dancing roll, on regulation cylindrical roller body 3, the position of anti-deflection device 2, makes anti-bias dress Put that the distance between one end that 2 external diameters are little is paper width 1.05 ~ 1.10 times.Again with bolt through hole 5, location, will be anti- Deflection device 2 is fixed on cylindrical roller body 3.The connecting rod 1 of cylindrical roller body 3 end is easy to the anti-local derviation of zero-speed splicer Paper bowl is arranged on the support of storage paper storehouse.By the antiskid groove 6 of cylindrical roller body 3 interlude, when dancing roll is when mobile, can keep away Exempt from paper landing.
