The 4th movement guide roller 34 dynamic coordinate.
For the ease of diagram, the spring in Fig. 3 installation diagrams only illustrates the portion between fixed block and the second movement guide roller
Point, and really extend to fast pulley from fixed block.
The present invention operation principle be:The stress after fixed block in left side and the fixed block on right side are promoted by cylinder, to
Medial movement, because left lead wheel group is identical with the operation principle of both right side guide roller groups, by taking left lead wheel group as an example
Illustrate.
Fixed block 30 moves inward after being promoted, and promotes the first mobile guide wheel 21 to move inward, due to first
Mobile guide roller 31 drives the left slide bar movement of the left slide bar in top and bottom, due to be provided with the left slide bar in top the left push rod in top and
The right push rod in top, the left push rod in bottom and lower right push rod are installed on the left slide bar in bottom, so when the first mobile guide wheel approaches
During the second movement guide roller, the left push rod of the left push rod in top and bottom continues to press on the second movement guide roller 22 and led close to the 3rd fixation
Line wheel 23, the right push rod in top and lower right push rod will promote the 5th movement guide roller 35 of right side guide roller group close to the 4th movement
Guide roller 34, until fixing guide roller 33 close to the 3rd.
Because the cylinder on right side promotes the first movement guide roller 31 on right side to move simultaneously, the second movement guide roller 32 also can
Generation identical is moved, anterior right slide bar and the right slide bar in rear portion and then the left push rod movement of the anterior left push rod of drive and rear portion, anterior
Left push rod, the left push rod in rear portion promote the 5th movement guide roller 25 of left lead wheel group close to the 4th movement guide roller 24, until
Close to the 3rd movement straight line wheel 23.
After cylinder is stopped, the fixed block 20 of left lead wheel group and the fixed block 30 of right side guide roller group are in bullet
Resetted in the presence of spring, and then drive respective side(Left side and right side)First movement guide roller, second movement guide roller, the 4th
Mobile guide roller and the 5th movement guide roller reset.
