Background technology
Along with the fast development of printing packaging industry, printing machine is widely used in printing house.Printing machine generally is comprised of mechanisms such as defeated paper, location, printing, collections, its operation principle is as follows: the writings and image that first will print is made forme, be contained on printing machine, then China ink is coated on forme to the zone that writings and image is arranged by artificial or printing machine, be transferred to directly or indirectly again paper or other stocks (as textile, metallic plate, plastic cement, leather, timber glass and pottery etc.) upper, thereby copy the printed matter identical with forme.
The endless-belt transmission is drive disk assembly the most general on printing machine, and endless-belt just there will be the loosening situation of skidding in use for some time, needs to change.But due to the belt shaft complicated structure of printing machine, the disassembling, assembling and replacing belt is very inconvenient, has a strong impact on production efficiency, need to be improved.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of belt shaft structure with quick-replaceable endless-belt device be applied on printing machine, its simple and ingenious structure, easy accessibility, can realize the quick-replaceable of belt, reduce labour intensity, enhance productivity.
According to technical scheme provided by the invention: the belt shaft structure with quick-replaceable endless-belt device, comprise belt shaft, belt wheel, the first upper bracket, the second upper bracket and quick-replaceable endless-belt device, the first upper bracket, the second upper bracket is fixed on the wallboard of printing machine both sides by gland and screw respectively, belt wheel is arranged on belt shaft, the belt shaft first end supports and is arranged on quick-replaceable endless-belt device by bearing assembly, quick-replaceable endless-belt device is arranged on the first upper bracket, belt shaft the second end directly supports and is arranged on the second upper bracket by bearing assembly, it is characterized in that: described quick-replaceable endless-belt device comprises support shaft, split ring and minor axis, described support shaft is fixedly connected on the first upper bracket, the axial centre of support shaft is provided with centre bore, minor axis one end inserts in the centre bore of support shaft, the minor axis other end is provided with the installation spindle nose, installs in spindle nose and is provided with the installation cavity for the back(-)up belt axle, described split ring is fastened on minor axis also fastening by holding screw, and split ring is at support shaft and the movable dismounting of split ring is installed between spindle nose.
As a further improvement on the present invention, described bearing assembly comprises spacer ring, bearing and shaft block ring, and described spacer ring and bearing holder (housing, cover) are contained on the axle journal of belt shaft, and spacer ring is on one side by post-axis neck step, the spacer ring another side withstands bearing inner race, and described bearing another side tightens fixing by shaft block ring.
compared with prior art, advantage is in the present invention:simple and ingenious structure of the present invention, easy accessibility, can realize the quick-replaceable of belt, reduces labour intensity, enhances productivity.
The accompanying drawing explanation
The installation situation schematic diagram that Fig. 1 is endless-belt on printing machine.
Fig. 2 is that D-D in Fig. 1 is to cutaway view.
