Fig. 5 be by the band bearing unit sectional side elevation and
Fig. 6 be printing machine in the hopper zone from above the view seen, wherein, band bearing unit and conveyer belt are all taken away;
The printing machine of describing in Fig. 1 has a frame with two sidewalls 1 and 2, and wherein, the first side wall 1 is clear that in Fig. 3 second sidewall shows in Fig. 1 and 2.
A circulating conveyer belt 4 is around 5,6 operations of two rollers, and roller 5,6 is vertically settled with spacing and with the sidewall of printing machine mutually, that is the belt section in the top of conveyer belt 4 contacts with four forming rolls (plate cylinder) 3.
These two rollers 5,6 are not directly to be placed on the printing machine, but are placed on the side member 7,8 of a band supporting arrangement 9, and this supporting arrangement 9 constitutes one can be from the unit that printing machine takes off.This supporting arrangement 9 is as comprising side member 7,8 describing in detail in the Figure 4 and 5, roller 5,6 and 4 opposed pressure rolls 10, and they are expressed to conveyer belt 4 on the shaping roller 3 when printing machine moves.This opposed pressure roll 10 is single adjustable, as can be seen from Figure 5.
Substrate that prints or paper are transported on this conveyer belt 4 by an automatic sheet feeder that does not show, its (4) are driven by roller 5 or 6, and paper is by the surface adhesive on conveyer belt 4 or by this active force, and in the printed slot between shaping roller 3 and the opposed pressure roll 10, transmit, so that then arrive on the paper feeder that does not show.
In order to make the band supporting arrangement fixing in printing machine, on each sidewall 1,2 of printing machine, settle a plurality of retaining elements, it is placed on the periphery of the side member 7,8 of being with supporting arrangement 9, and this moment, supporting arrangement 9 placed printing machine.As showing at Fig. 1 to 3, this retaining element is exactly respectively a left side and adjusting locating part 11 top, 12, they are positioned on the left-hand end of side 7 and 8, also having one is that flexible locating part 13 is positioned on the right-hand end of side member 7 and 8, its (13) is a rotatable lever of settling on sidewall 1 and 2, one end thereof can be connected on side member 7 and 8, is the roller lever and is positioned at the bottom side of side member 7 and 8 and approximately therebetween on the position and its other end is applied in effect by an adjustable compression spring 14 and also have one.
This roller lever comprises a wall spare 15, and its end is placed on sidewall 1 and 2 pivotally and settles a roller 16 on its other end.Fix the wide part 17 of a type on side member 7 and 8 respectively, it has a curvilinear surface 18 facing to roller 16.During the run location of the band supporting arrangement 9 that shows at Fig. 1 to 3, each wall spare 15 is on such position, at this moment, roller 16 is expressed on the part that increases of curvilinear surface 18 and mode according to this, this corresponding side member 7 and 8 is expressed to be regulated on the locating part 11,12 and on the locating part 13 of spring.
Be connected a curved lever pull bar 19 with each wall spare 15, its end is fixed on that an axle by sidewall 1 and 2 is gone up and it is on the dead-centre position of stretching out in Fig. 1 to 3.So stable position can be used as tension spring 21 preferred or that show by a sketch in addition and realizes that it is moved curved lever pull bar 19 on the locating part 22 of sidewall 1 and 2 to.This 20 extends through whole printing machine, and wherein, an end of axle 20 is connected with a handle or analog on the lateral surface of printing machine.
