Abstract
The utility model relates to a film processing field discloses a multisection roller unwinding device, has contained membrane roll core, has unreeled the dop, has fixed the deflector roll to reach the deflector roll that floats, and fixed deflector roll reaches the deflector roll structure that unsteady deflector roll all adopted 2 section at least rollers to make up. The deflector roll structure is that every section roller respectively can independently rotate at the synthetic whole piece deflector roll that is of the coaxial set of the rolls of spindle interlude multisection. In the application that the film unreeled, for ordinary single section roller deflector roll, tension that the deflector roll of multisection roller combination can even film reduces unreeling tensile fluctuation, improves the stability that unreels, solved because of the unstable film that the causes bubble of tension unreels, the scheduling problem wrinkles.
Description
Technical field
The utility model relates to thin-film unreeling equipment, is widely used in the mechanical equipment of film series products processing, especially for the more piece roller unwinding device that tensile requirements is very harsh.
Background technology
Have employing in the unwinding device of prior art: film volume core, unreel dop, transition deflector roll, float this configuration of deflector roll.Unreel in process, because be limited to uneven film thickness, film volume tension force cross the situations such as pine, therefore film volume is not the cylinder of a pure circle, under low-tension unreels situation, film is through common transition deflector roll and floating deflector roll, can fitfull be had to vibrate always, cause at film seriously unbalanced at horizontal generation tension force, also the shakiness of longitudinal tension force can be fed through to, thus affect the stability of unwinding tension and the smooth running of film, the further production process affecting subsequent process steps, finally have impact on quality and the performance of film.
Utility model content
The utility model, for the deficiencies in the prior art, provides a kind of more piece roller unwinding device, and the guide roller structure of the coaxial roller combination of more piece effectively evenly can unreel the tension force of film, reduces the fluctuation of unwinding tension, improves the stability unreeled.And effectively can be vented and can film be flattened, substantially increase film appearance, make rolling more smooth.
The utility model solves the technical scheme that its technical matters adopts: a kind of more piece roller unwinding device, contain film volume core, unreel dop, stationary guide roller and floating deflector roll, described stationary guide roller and floating deflector roll all adopt the guide roller structure of the coaxial roller combination of at least 2 joint.
As a kind of optimal way, a kind of more piece roller unwinding device, is characterized in that: guide roller structure comprises the coaxial roller of 3 to 6 joint.
Preferentially, the mandrel two ends of deflector roll of floating, are connected with swinging support part by aligning ball bearing of main shaft, can realize longitudinal oscillation and horizontal aligning is floating.In addition, therefore the mandrel of deflector roll of floating possesses swing along strut member axle center of rolling to each side and twisting.Certain film has application force to floating deflector roll, and this power needs to be added in the elastomeric element of strut member of rolling to each side or pneumatic element provides.
As further optimal way, a kind of more piece roller unwinding device, is characterized in that: floating deflector roll can connection bit displacement sensor, controls for tension force.Displacement pickup can be angular-motion transducer also can be linear displacement transducer, for detecting the displacement of floating deflector roll, to realize unreeling speeds control.
Preferentially, often save roller two ends and deep groove ball bearing is installed, with the position of circlip for bore Limit Bearing.Often save between roller and be provided with spacer, spacer withstands the inner ring of deep groove ball bearing, and by the gap between spacer restriction roller.
The utility model more piece roller unwinding device, film twists in the process unreeled, can independently rotate because often saving roller in guide roller structure, and laterally can float by aligning, when film is by floating deflector roll, in the moment of coated roll surface, floating deflector roll can not only adapt to the thickness difference of film in longitudinal direction, also the Tension Difference of film in transverse direction can automatically be adapted to, film can be consistent at horizontal tension force everywhere, further make film can keep identical tension ground, entirely carry, improve film appearance, make rolling more smooth.

Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.
A kind of more piece roller unwinding device, please refer to Fig. 1 and Fig. 2.The utility model more piece roller unwinding device primarily of film volume and core 3, unreel dop 5, float deflector roll 1, stationary guide roller 2 and tenslator composition.
More piece roller unwinding device of the present utility model, please refer to Fig. 1.Floating deflector roll 1 and stationary guide roller 2 all adopt the guide roller structure of the coaxial roller combination of more piece.
More piece roller unwinding device of the present utility model, please refer to Fig. 3 and Fig. 4.This guide roller structure sentencing three joint roller combinations is example explanation.Guide roller structure is that interspersed 3 joint rollers 10 are combined into a whole piece deflector roll on mandrel 7, often saves roller 10 two ends and is provided with deep groove ball bearing 11, with the position of circlip for bore 12 Limit Bearing.Often save between roller 10 and be provided with spacer 13, spacer 13 withstands the inner ring of deep groove ball bearing 11, and limits the gap between roller 10 by spacer 13.
More piece roller unwinding device of the present utility model, please refer to Fig. 3.In more piece roller combination guide roller structure, often roller 10 is each can independently rotate for joint.
More piece roller unwinding device of the present utility model, please refer to Fig. 1.Aligning ball bearing of main shaft 8 is installed at float mandrel 7 two ends of deflector roll 1, then is connected with swinging support part 9, can realize longitudinal oscillation and horizontal aligning floats.
Linear displacement transducer 4 is arranged on the swinging support part 9 of one end, to detect the change in location of floating deflector roll 1, and the rotating speed of closed loop control film volume and core 3.Certainly angular-motion transducer also can be used here to feed back.
More piece roller unwinding device of the present utility model, please refer to Fig. 1.Mandrel 7 two ends of stationary guide roller 2 are arranged on wallboard 6.
In thin-film unreeling process, as shown in Figure 2, the film of film volume 3 is when stationary guide roller 2, and each joint roller 10 in deflector roll can adapt to the thickness difference of film automatically, and even tension force, avoids film wrinkling.Film, when floating deflector roll 1, because mandrel 7 two ends are provided with self-aligning ball bearing 8, makes floating deflector roll 1 laterally can float by aligning, automatically adapts to the Tension Difference of film in transverse direction.The often joint roller 10 floated in deflector roll 1 can independently rotate, and the Tension Difference that can cause at the uneven thickness longitudinally adapting to film, maintains constant tension, makes to unreel more stable.
More than that the utility model more piece roller unwinding device is set forth; the utility model is understood for helping; but embodiment of the present utility model is not restricted to the described embodiments; any do not deviate from the utility model principle under do change, modification, substitute, combination, simplify; all should be the substitute mode of equivalence, be included within protection domain of the present utility model.
