Detailed description of the invention
As shown in Figure 1,2,3, 4, Special guide rail of two-way plastic film stretch sheet of the present invention, comprise the guide rail body 3 be integrally made up of a crossbeam 31, two side plates 32 and a projection 33, the two ends that described two side plates 32 are positioned at crossbeam 32 are I shape, and described projection 33 is positioned at the middle part above described crossbeam 31; Location-plate 4 is fixed with above described projection 33, end slide plate 5 is fixed with above described crossbeam 31 side, the sideslip version 6 be fixed on inside a side plate 32 is provided with above slide plate of the described end 5, described upper location-plate 4, between end slide plate 5 and sideskid 6, be provided with slide 7, described slide 7 along guide rail body 3 direction, at upper location-plate 4, can slide between end slide plate 5 and sideskid 6; Described slide 7 is provided with chain 10 and fixture 8, and described fixture 8 is for fixed plastics film.
Described guide rail body 3 two ends are respectively provided with one for connecting the rotating shaft supporting plate 1 of another guide rail body, and described two rotating shaft supporting plates 1 are not at sustained height, and the difference in height of two rotating shaft supporting plates 1 is the thickness of described rotating shaft supporting plate 1.Described rotating shaft supporting plate 1 is fixed by screws in the below of described crossbeam 31.The outside at side plate 32 two ends of described guide rail body 3 is provided with the connecting plate 2 for fixing another guide rail body.Described upper location-plate 4, end slide plate 5 and sideskid 6 are fixed by screws in described guide rail body 3.
Described slide 7 is made up of end face 71, bottom surface 72 and side 73, and described end face 71 contacts with the lower surface of described upper location-plate 4, and described bottom surface 72 contacts with the upper surface of slide plate of the described end 5, and described side 73 contacts with the inner surface of described sideskid 6.Between described end face 71 and the lower surface of upper location-plate 4, between the upper surface of bottom surface 72 and end slide plate 5, between side 73 and the inner surface of sideskid 6, have oil storage tank, play the effect of lubrication.Be fixed with a locating shaft 9 between described end face 71 and bottom surface 72, described locating shaft 9 is fixed on described chain 10.Described end face 71 side is provided with location-plate 74, and described location-plate 74 is connected with fixture 8.Described fixture 8 is fixed on described location-plate 74 by bolt, spring washer and plain washer.
The operation principle of Special guide rail of two-way plastic film stretch sheet of the present invention is as follows:
By sunk screw, end slide plate 5 is fixed on the bottom surface of guide rail body 3, sunk screw is fixed on sliding side plate 6 on the side of guide rail body 3, chain 10 is assemblied on slide 7 by locating shaft 9, upper location-plate 4 is fixed on by soket head cap screw on the end face of guide rail body 3, and slide 7 can be pushed down, slide about 7 can be made like this to locate, slide 7 carries out left and right by sideskid 6 and locates, fixture 8 is fixed on slide 7 by hex bolts, spring washer, plain washer, and rotating shaft supporting plate 1 is fixed on below guide rail body 3 by soket head cap screw.The face that end slide plate 5 and sideskid 6 contact with slide 7 has oil storage tank, be convenient to carry out effectively lubricating when slide 7 moves fast, reduce and end slide plate 5, frictional force between sideskid 6, upper location-plate 4, there is certain difference in height between the two in each one of rotating shaft supporting plate about 1, be convenient to being coupled to each other of another joint guide rail, to ensure that every part guide rail can deliver to exchange, greatly reduce assembly difficulty like this.Connecting plate 2 is fixed on the side of guide rail body 3 by soket head cap screw, be convenient to guide rail and another part guide rail in the middle of connects and location, and the guiding of slide 7 by being, reduces the vibration in moving.
Embodiment recited above is only be described the preferred embodiment of the present invention; not scope of the present invention is limited; do not departing under the present invention designs spiritual prerequisite; the various distortion that the common engineers and technicians in this area make technical solution of the present invention and improvement, all should fall in protection domain that claims of the present invention determine.
