Utility model content
The purpose of this utility model is to provide a kind of Full-automatic tension and controls unwinding device, and this device can control tension force during blowing automatically, makes tension force keep uniformity, can not produce continuously material sagging or time loose time tight drawback.
For achieving the above object, the utility model takes following technical scheme:
A kind of Full-automatic tension controls unwinding device, comprise base, it is characterized in that, base is equipped with dispensing shaft, dispensing shaft is fixedly equipped with friction disc, bracing member is movably arranged on dispensing shaft, bracing member is equipped with guide roller set and belt support plate, deceleration belt one end is fixed on base, and middle part contacts with friction disc, and the other end is fixed on belt support plate.
Preferably, described base comprises the first riser and the second riser, described dispensing shaft is arranged on the first riser and the second riser through clutch shaft bearing and the second bearing respectively, and described friction disc, bracing member, belt support plate and deceleration belt are all between the first riser and the second riser.
Further, be fixed with crossbeam at described first riser and the second riser side, described deceleration belt is fixed on crossbeam and friction strides across described friction disc and described belt support plate fixes.
Further, described guide roller set comprises the first deflector roll and the second deflector roll, and described bracing member one end is sleeve, is equipped with backup bearing in this sleeve, and the inner ring of backup bearing is arranged on described dispensing shaft.
Further, described bracing member is equipped with tension retaining mechanism.Tension retaining mechanism is spring or cylinder.
The beneficial effect of technique scheme is, during use, material volume is through on dispensing shaft, then material strip is walked around deflector roll, and advanced by the traction of materials mechanism, produce tension force when material strip is pulled and act on deflector roll, deflector roll drives bracing member to produce certain deflection around dispensing shaft, bracing member loosens deceleration belt by belt support plate again, deceleration belt and friction disc are separated, and reduce friction like this, and emptying roller and material volume are easily rotated; If material strip tension force diminishes, then bracing member can reset because of gravity because being obliquely installed, now deceleration belt contacts with friction disc and produces friction wheel and hinder emptying roller to rotate, avoid releasing too much material strip, therefore the basic uniformity of tension force can be kept, ensure the tensioning continuity of feeding, be convenient to the materials of next link.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further:
As depicted in figs. 1 and 2, base 1 is combined by the first riser 2 and the second riser 3, be equipped with crossbeam (not shown) at the first riser and the second riser side, emptying roller 5 is arranged on the first riser by clutch shaft bearing, is arranged on the second riser by the second bearing.Emptying roller 5 between the first riser and the second riser is equipped with bracing member 7, bracing member 7 one end is sleeve 8, backup bearing is equipped with in sleeve 8, the inner ring of backup bearing is fixedly mounted on dispensing shaft 5, like this, emptying roller 5 can at clutch shaft bearing and the second rotation on bearings, and bracing member 7 can rotate relative to emptying roller 5.Emptying roller 5 is horizontally disposed with, and bracing member 7 is positioned at the plane perpendicular with emptying roller, simultaneously by being certain angle of inclination relative to vertical direction, as 15 ~ miter angle or other acute angles, and the direction of rotation of this direction of tilt and emptying roller.Bracing member 7 is equipped with the first deflector roll 10 and the second deflector roll 11, first deflector roll 10 and the second deflector roll 11 parallel with emptying roller 5.Emptying roller can be provided with the fixture block of fixing material volume, and when being through on dispensing shaft by material volume, fixture block is fixed from both sides by material volume and clamps.Stretch to materials mechanism after material strip on material volume walks around the first deflector roll 10 and the second deflector roll 11, and produce tension force under the traction of materials mechanism, pull material volume and dispensing shaft to rotate simultaneously.Dispensing shaft 5 one end is fixedly equipped with friction disc 6, this example, between the first riser and the second riser, is wound with deceleration belt 12 at friction disc 6 first half, and deceleration belt 12 one end is fixed on the crossbeam of base, the other end is fixed on belt support plate 9, and belt support plate 5 is fixed on sleeve 8.
When material volume 21 produces tension force under tractive force, the first deflector roll 10 and the second deflector roll 11 and bracing member 7 is pulled to produce small angle deflection around emptying roller 5 to vertical direction, such deceleration belt no longer rubs friction disc 6, thus emptying roller is easily rotated, release more material strips to avoid making overtension, when tension force diminishes, bracing member 7 is returned to original position by self gravitation or the tension force holding structure that installs additional, deceleration belt then contacts with friction disc to produce and rubs, thus hinder emptying roller to rotate, make blowing slack-off, thus tension force is increased.Therefore, this device can auto-adjustment control blowing time material strip Tensity size, make even tension consistent, be convenient to the production of next link.
Bracing member also can be equipped with tension retaining mechanism 20, can serve as with spring or cylinder, spring or cylinder one end are positioned on bracing member, and the other end is positioned on base or other equipment.Tension retaining mechanism makes bracing member rotation be maintained within a certain range, and prevents it from producing upset when receiving larger pulling force.In the utility model, base also can make other patterns.
