A kind of spread roller devices that is applied to layout machine
Technical field
The invention belongs to cutting technical field, refer in particular to a kind of spread roller devices that is applied to layout machine.
Background technology
At present, in prior art there are some defects in the structure design of the spread roller of layout machine: it is, on the surface of ten hexagon running rollers, slide rail is installed, and spread blade is installed on slide rail again, and its structure design is too complicated, has indirectly increased the volume of spread roller; Limited due to processing technology, the straightness accuracy of roller surface and planeness cannot be guaranteed, and precision is not high; The slide rail parallelism that causes being arranged on running roller is not high; And then causing the resistance of motion of spread blade very large, the straightness accuracy of blade movement can not guarantee; Assembly technology is complicated, and running roller precision is not high, and slide rail serious wear, service life is short, productive costs is high.
Summary of the invention
The object of this invention is to provide a kind of spread roller devices that is applied to layout machine, it is simple and compact for structure, and processing technology is simple, and transmission accuracy is high, long service life, and productive costs is low.
The object of the present invention is achieved like this:
A kind of spread roller devices that is applied to layout machine, comprise axle drive shaft and spread blade, it is characterized in that: described spread blade pass is crossed guiding mechanism and is connected with axle drive shaft, described guiding mechanism is: on axle drive shaft, be arranged with two supporting disks that arrange with axle drive shaft concentric, on two supporting disks between two supporting disks, be circumferentially evenly equipped with some spaced guide pillars, on guide pillar, slide and be provided with slide block, described spread blade is fixedly connected on slide block.
Two described adjacent guide pillars parallel setting, and the two ends of described guide pillar are all fixed by axle head screw and supporting disk.
In above-mentioned a kind of spread roller devices that is applied to layout machine, described guiding mechanism is two one group use, and the left and right two ends of axle drive shaft are symmetrically arranged with one group of guiding mechanism.
In above-mentioned a kind of spread roller devices that is applied to layout machine, on described slide block, offer two axially extending bores, in two axially extending bores, be passed in respectively on two described guide pillars.
In above-mentioned a kind of spread roller devices that is applied to layout machine, on the axle drive shaft in described two guiding mechanisms outside, be equipped with cam, on spread blade, be fixed with the bearing being connected with cam drive.
The present invention compared to existing technology outstanding and useful technique effect is:
1, the present invention has cancelled the design of polygon running roller, adopts a tiny axle drive shaft, guiding mechanism is installed on axle drive shaft and is used for sliding block joint spread blade, so structure design is simply compact.
2, guiding mechanism of the present invention is easy to make, and processing technology is less demanding, and productive costs is low.
3, the wearing and tearing of guiding mechanism of the present invention are little, long service life.

The specific embodiment
Below in conjunction with accompanying drawing, with specific embodiment, the invention will be further described, referring to Fig. 1-3:
A kind of spread roller devices that is applied to layout machine, comprise axle drive shaft 1 and spread blade 2, described spread blade 2 is connected with axle drive shaft 1 by guiding mechanism, described guiding mechanism is: on axle drive shaft 1, be arranged with two supporting disks 3 that arrange with axle drive shaft 1 concentric, on two supporting disks 3 between two supporting disks 3, be circumferentially evenly equipped with some spaced guide pillars 4, on guide pillar 4, slide and be provided with slide block 5, described spread blade 2 is fixedly connected on slide block 5.
Structural principle of the present invention is: guide pillar 4 distributes around axle drive shaft 1, all guide pillars all parallel setting with axle drive shaft, the slide block 5 arranging on guide pillar 4 also distributes around axle drive shaft 1, makes thus spread blade shroud be arranged into cylindrical shape around axle drive shaft 1, has formed spread roller.
Above-mentioned wherein two adjacent guide pillars are positioned at same plane and are parallel to each other, and the two ends of guide pillar are all fixed by axle head screw and supporting disk.
Guiding mechanism is two one group use, and the left and right two ends of axle drive shaft are symmetrically arranged with on one group of slide block 5 described in guiding mechanism and offer in 6, two axially extending bores of two axially extending bores and be passed in respectively on two described guide pillars 4.
On the axle drive shaft 1 in described two guiding mechanisms outside, be equipped with cam 7, on spread blade 2, be fixed with the bearing 8 being connected with cam drive.Cam 7 coordinates with the transmission of spread blade 2 head bearings 8 makes spread blade 2 produce back and forth motion of translation of left and right.
Above-described embodiment is only preferred embodiment of the present invention, not limits the scope of the invention according to this, therefore: all equivalences of doing according to structure of the present invention, shape, principle change, within all should being covered by protection scope of the present invention.
