Abstract
The invention relates to a belt shaft structure with a rapid annular belt changing device. The belt shaft structure comprises a belt shaft, belt wheels, a first upper bracket, a second upper bracket and the rapid annular belt changing device. The belt shaft structure is characterized in that the rapid annular belt changing device comprises a bracket shaft, a split ring and a short shaft, wherein the bracket shaft is fixedly connected to the first upper bracket, a central hole is formed in the axial center of the bracket shaft, one end of the short shaft is inserted into the central hole of the bracket shaft, a mounting shaft head is arranged on the other end of the short shaft, and a mounting cavity form supporting the belt shaft is formed in the mounting shaft head; the split ring is clamped and sleeved on the short shaft, is fastened through a fastening screw, is located between the bracket shaft and the mounting shaft head and can be movably detached. The belt shaft structure is simple and artful, is convenient to dismount and mount and is capable of realizing rapid changing of a belt; the labor intensity is lowered, and the production efficiency is improved.
Description
Technical field
The present invention relates to the belt shaft be applied on printing machine, specifically there is the belt shaft structure of quick-replaceable endless-belt device, belong to printing mechanism technical field.
Background technology
Along with the fast development of printing packaging industry, printing machine is widely used in printing house.Printing machine is generally made up of mechanisms such as defeated paper, location, printing, collections, its operation principle is as follows: the writings and image that first will print makes forme, dress on the printer, then ink is coated in by artificial or printing machine region forme having writings and image, be transferred to directly or indirectly again on paper or other stocks (as textile, metallic plate, plastic cement, leather, timber glass and pottery etc.), thus copy the printed matter identical with forme.
Endless-belt transmission is drive disk assembly the most general on printing machine, and endless-belt just there will be loosening slippery conditions in use for some time, needs to change.But due to the belt shaft complicated structure of printing machine, disassembling, assembling and replacing belt is very inconvenient, has a strong impact on production efficiency, needs 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, the quick-replaceable of belt can be realized, 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, first upper bracket, second upper bracket and quick-replaceable endless-belt device, first upper bracket, second upper bracket is fixed on the wallboard of printing machine both sides respectively by gland and screw, belt wheel is arranged on belt shaft, belt shaft first end is arranged on quick-replaceable endless-belt device by bearing assembly supporting, quick-replaceable endless-belt device is arranged on the first upper bracket, belt shaft second end is directly supported by bearing assembly and is arranged on the second upper bracket, 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 is inserted in the centre bore of support shaft, the minor axis other end is provided with installation spindle nose, installs in spindle nose the installation cavity be provided with for back(-)up belt axle, described split ring to be fastened on minor axis and fastening by holding screw, and split ring is at support shaft and install between spindle nose, the movable dismounting of split ring.
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 by post-axis neck step, spacer ring another side withstands bearing inner race, and described bearing another side is fixing by shaft block ring clamping.
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.
Accompanying drawing explanation
Fig. 1 is the installation situation schematic diagram of endless-belt on printing machine.
Fig. 2 is that D-D in Fig. 1 is to sectional view.
Fig. 3 is that J-J in Fig. 2 is to sectional view.
Detailed description of the invention
Below in conjunction with concrete drawings and Examples, the invention will be further described.
As shown in Figure 1: the belt shaft structure with quick-replaceable endless-belt device in embodiment forms primarily of the first upper bracket 1, support shaft 2, split ring 3, minor axis 4, belt shaft 5, belt wheel 6, spacer ring 7, bearing 8, shaft block ring 9, second upper bracket 10, gland 11, screw 12 and holding screw 13.
As shown in Fig. 1 ~ Fig. 3, first upper bracket 1, second upper bracket 10 is fixed on the wallboard of printing machine both sides respectively by gland 11 and screw 12, belt wheel 6 is arranged on belt shaft 5, and belt shaft 5 first end is arranged on quick-replaceable endless-belt device by bearing assembly supporting; Quick-replaceable endless-belt device forms primarily of support shaft 2, split ring 3 and minor axis 4, support shaft 2 is fixedly connected on the first upper bracket 1, the axial centre of support shaft 2 is provided with centre bore, minor axis 4 one end is inserted in the centre bore of support shaft 2, minor axis 4 other end is provided with installs spindle nose 4a, installs in spindle nose 4a the installation cavity be provided with for back(-)up belt axle 5; Described split ring 3 to be fastened on minor axis 4 and fastening by holding screw 13, and split ring 3 is at support shaft 2 and install between spindle nose, the movable dismounting of split ring 3; Belt shaft 5 second end is directly supported by bearing assembly and is arranged on the second upper bracket 10.
In the present invention, described bearing assembly forms primarily of spacer ring 7, bearing 8 and shaft block ring 9, and described spacer ring 7 and bearing 8 are sleeved on the axle journal of belt shaft 5, and spacer ring 7 is by post-axis neck step, spacer ring 7 another side withstands bearing 8 inner ring, and described bearing 8 another side clamps fixing by shaft block ring 9.
Described quick-replaceable endless-belt device mainly by mobile first upper bracket 1, makes there are enough gaps to change conveyer belt between the first upper bracket 1 and wallboard.During embody rule, by unclamping holding screw 13, can pull down split ring 3, such first upper bracket 1 just can the direction of original split ring 3 in the past move, just there are enough gaps between such wallboard and the first upper bracket 1, thus just can have ensured quick-replaceable endless-belt.
