Abstract
The utility model discloses a dancing roll device of a printing machine. The dancing roll device of the printing machine comprises a dancing roll. Both ends of the dancing roll are respectively and fixedly arranged in two supporting seats through two bearings; a connecting hole is formed in each supporting seat, and each supporting seat is fastened to a wallboard through a shaft shoulder-type bolt and the corresponding connecting hole. The dancing roll device of the printing machine disclosed by the utility model has the advantages that the structure is simple and compact, the cost is low, processing and manufacturing are convenient, installation and adjustment are simple and convenient, and the like.
Description
Technical field
The utility model is mainly concerned with field of printing machinery, refers in particular to a kind of printing machine paper guiding roller device.
Background technology
In business rotary press, much more very paper guiding roller device is a kind of essential and use device.The printed material reset condition of rotary press is paper roll, as shown in Figure 1, before printing, must be launched into paper tape 15; Paper tape 15 is until before being cut off, paper tape 15 opening a book, guide, stablizing the processes such as paper road and all must complete by dancing roll 4 in whole printing process.For example, paper tape 15, after opening a book, lead through some dancing rolls 4, just enters folding machine.
Because the required precision of typography itself is higher, this will will rotate flexibly by differentiate paper bowl 4 in leading paper process, require dancing roll 4 two ends of dancing roll 4 axiality in process own higher, require dancing roll 4 dancing roll 4 in installation process higher with the depth of parallelism of main printing roller.
In conventional paper guiding roller device, it itself is exactly an assembly, as shown in Figure 2, tradition paper guiding roller device comprises dancing roll fixed axis 11, dancing roll body 10, dancing roll inner bearing 12 and dancing roll plug 13, the inside, middle section of dancing roll body 10 is provided with two dancing roll inner bearings 12, it is spacing that two dancing roll inner bearings 12 are undertaken by dancing roll plug 13 respectively, between two dancing roll plugs 13, by mounting screw 9, connects; The two ends of dancing roll body 10 are installed on wallboard 14 by supporting seat 2 respectively, and are provided with dancing roll fixed axis 11 on wallboard 14.Above-mentioned this paper guiding roller device, structure is very complicated, and processing and manufacturing cost is higher.After paper guiding roller device assembles, be by supporting seat 2 integral installations on the wallboard 14 of frame.Due to dancing roll body 10 two ends axialities and with the requirement of the master rotor depth of parallelism, need the position of constantly adjusting supporting seat 2 can meet installation accuracy.As can be seen here, traditional paper guiding roller device, mounting process is very complicated, and adjustment difficulty is larger.
Utility model content
The technical problems to be solved in the utility model is just: the technical problem existing for prior art, the utility model provide a kind of simple and compact for structure, with low cost, processing and fabricating convenient, install and adjust easy printing machine paper guiding roller device.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
A kind of printing machine paper guiding roller device, comprise dancing roll, the two ends of described dancing roll are fixed in a supporting seat by a bearing respectively, offer a connecting hole described in each in supporting seat, and by a shaft shoulder type screw and connecting hole, are fixed on wallboard respectively.
As further improvement of the utility model:
On described dancing roll, the bearing of one end is completely fixed in supporting seat by two jump rings, and other one end is free end.
An attaching nut who is used for shaft shoulder type screw fit is housed in supporting seat described in each, and each is spacing with two plain cushions and screw in described attaching nut's outside.
Compared with prior art, the utility model has the advantage of:
1. printing machine paper guiding roller device of the present utility model, simple and compact for structure, with low cost, processing and fabricating convenient, except roller and supporting seat, all the other are standard component entirely.
2. printing machine paper guiding roller device of the present utility model, interchangeability is strong, uses in a large number standard component and general part, and interchangeability and versatility are more intense.
3. printing machine paper guiding roller device of the present utility model, without adjusting, precision is high, because having utilized dexterously the polarization of shaft shoulder type screw, after installing, can reach design object, without regulate and precision high.
4. printing machine paper guiding roller device of the present utility model, cost is low, the extensive application of standard component and general part and the simple manpower of saving is installed, cost is more much lower than conventional method.

The specific embodiment
Below with reference to Figure of description and specific embodiment, the utility model is described in further details.
As shown in Figure 3, printing machine paper guiding roller device of the present utility model comprises dancing roll 4, and the two ends of dancing roll 4 are fixed in a supporting seat 2 by a bearing 5 respectively, and the outer ring of bearing 5 is separately fixed in supporting seat 2.In each supporting seat 2, offer a connecting hole (as articulation hole), and by a shaft shoulder type screw 1 and connecting hole, be fixed on wallboard 14 respectively.After shaft shoulder type screw 1 is tightened, whole dancing roll 4 has just been securely fixed on wallboard 14, because shaft shoulder type screw 1 self has polarization, so can guarantee accurately dancing roll 4 axiality and without other adjusting.After dancing roll 4 installs, due to end mounted bearing 5, dancing roll 4 also can flexible rotating, completes guiding function.
In the present embodiment, the bearing 5 of one end on dancing roll 4 (being right-hand member in figure) is completely fixed in supporting seat 2 by two jump rings 6, plays axial restraint effect, and other one end is free end; Except can eliminating error and expanding with heat and contract with cold, can also carry out the about 10mm of left and right adjusting, thereby adapt to different wallboards 14 spans like this, strengthen its interchangeability.
In the present embodiment, an attaching nut 3(is housed as hex nut in each supporting seat 2), each blocks attaching nut 3 outside but does not kill with two plain cushions 8 and screw 7, allows it have certain floatability, and this is conducive to shaft shoulder type screw 1 and is screwed into from outer end.
Below be only preferred embodiment of the present utility model, protection domain of the present utility model is also not only confined to above-described embodiment, and all technical schemes belonging under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, the some improvements and modifications not departing under the utility model principle prerequisite, should be considered as protection domain of the present utility model.
