Detailed description of the invention
For making those skilled in the art better understand the technical solution of the utility model, below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
As shown in figs. 1-7, embodiment of the present utility model discloses a kind of live roll assembly, for tensioning and the material film transmitting the bar shaped be stripped in loader, (the first guide can be connected with the first live roll 20 with the second guide the first live roll 20 that live roll assembly comprises the first guide and the second guide and is arranged between the two, also can not be connected with the first live roll 20), and at least the first live roll 20 can rotate; Distance between first guide and the second guide is less than the width of material film, and the first guide and the second guide are all convex for the first live roll 20 in the footpath of the first live roll 20.First guide, the second guide and the first live roll 20 can have multiple assembling mode, such as, at the two ends of the first live roll 20, two coaxial rotating shafts are set respectively, first guide and the second guide are separately fixed in two rotating shafts, other assembling modes can certainly be adopted, in the present embodiment, the first guide, the second guide and the first live roll 20 realize assembling by the axle 40 wearing three.
When utilizing live roll assembly of the present utility model to transmit material film, under the effect of tensile force, the centre portion on material film Width contacts with the first live roll 20, the both sides of material film and two guide contacts.So, because the distance between two guides is less than the width of material film, under the effect of tensile force, two guides make to expect that the one side (expecting the outside face of film) that the sticking part of both sides tool of film does not contact with the first live roll towards material film bends, and are bonded in the outside face of material film.All there is not viscosity in two surfaces of the material film after bending, cannot carry out bonding with miscellaneous part, so make expect film can be smooth and orderly enter collecting bin, finally avoid the obstruction of collecting bin, decrease the alarm probabilities of loader.
The reason of two lateral bucklings of material film can be made to be: the distance between two guides is less than the width of material film.Therefore, the concrete structure at the first live roll 20 place is installed according to the width of transmitted material film and loader, guide can have multiple different structure, and also there is different position relationships from the first live roll 20 in guide, but no matter which kind of structure guide has, and have which kind of position relationship with the first live roll 20, only the distance that need meet between the two is less than the width of material film, and can radial convex for the first guiding roller 20.
In a preferred embodiment of the present utility model, the first guide is the first track adjusting wheel 11, second guide is that the second track adjusting wheel 12, first track adjusting wheel 11 and the second track adjusting wheel 12 are coaxially arranged, and both diameters are all greater than the diameter of the first live roll 20.Selective guide wheel is as the benefit of guide: track adjusting wheel is easy to processing and installs, without the need to considering the problem of setting angle.
In a preferred embodiment of the present utility model, as shown in Figure 1, the first track adjusting wheel 11 and the second track adjusting wheel 12 are fixedly sleeved on the first live roll 20 respectively, and are positioned at the two ends of the first live roll 20.The live roll assembly of this kind of structure is for replacing the live roll of the 88mm in prior art on loader.
As shown in Figures 2 and 3, when loader install cannot provide enough installing spaces for live roll assembly time, and the first track adjusting wheel 11 and the second track adjusting wheel 12 cannot or without the need to being fixed on the first live roll 20 time, first track adjusting wheel 11 and the second track adjusting wheel 12 are fixed on loader, and respectively and the interval, two ends of the first live roll 20 arrange, and the wheel face of two track adjusting wheels is all formed with mounting plane 13, this mounting plane 13 is less than the diameter of track adjusting wheel to the distance in the center of circle, and this mounting plane is for being fitted in the mounting plane of loader.It is less that the said structure of two track adjusting wheels and set-up mode make live roll assembly take up room, and solves loader cannot install live roll assembly problem because installing space is less.The live roll assembly of this kind of structure is for replacing the live roll of the 72mm on loader of the prior art.
For improving the commonality of live roll assembly of the present utility model, in a preferred embodiment of the present utility model, as shown in Figures 4 to 7, live roll assembly also comprises coaxial the second live roll 30, second track adjusting wheel 12 arranged with the first live roll 20 and is fixed on one end of the second live roll 30.When needing live roll (length of live roll is 44mm) of replacing smaller length in prior art, the second live roll 30 can be made to be fixed with one end of the second track adjusting wheel 12 near the first live roll 20; When needing live roll (length of live roll is 56m) of replacing greater depth in prior art, the second live roll 30 can be made to be fixed with one end of the second track adjusting wheel 12 away from the first live roll 20, thus make can be formed between the first track adjusting wheel 11 from the second track adjusting wheel 12 two different distances, thus transmit the material film of two kinds of different in width.In the present embodiment, install the structure at live roll assembly place for loader, two track adjusting wheels need to be arranged to two kinds of structures too.As shown in Figure 6 and Figure 7, when loader cannot provide enough installing spaces for live roll assembly, and the first track adjusting wheel 11 cannot or without the need to being fixed on the first live roll 20 time, first track adjusting wheel 11 is fixed on loader, and and the first live roll 20 interval arrange, and two track adjusting wheels are also all formed with mounting plane 11.It is less that the said structure of two track adjusting wheels and set-up mode make live roll assembly take up room, and solves loader cannot install live roll assembly problem because installing space is less.As shown in Figure 4 and Figure 5, when loader can provide enough installing spaces for live roll assembly, first track adjusting wheel 11 is fixed on the first live roll 20, and be positioned at the first live roll 20 one end away from the second live roll 30, second track adjusting wheel 12 is fixed on the second live roll 20, and two track adjusting wheels are all without the need to arranging mounting plane 13.
Above embodiment is only exemplary embodiment of the present utility model, is not used in restriction the utility model, and protection domain of the present utility model is defined by the claims.Those skilled in the art can in essence of the present utility model and protection domain, and make various amendment or equivalent replacement to the utility model, this amendment or equivalent replacement also should be considered as dropping in protection domain of the present utility model.
