Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention will be described in detail: as shown in fig. 1, the Work-feeding means of a kind of easily tore film of the present invention, comprise the supply roll 11 carrying out rotating for supporting silt form d, the end of described supply roll 11 is fixed with brake plate 111, the bottom of described supply roll 11 is provided with brake axle 12, described brake axle 12 is provided with the brake body 122 carrying out braking for contacting brake plate 111, and one end of described brake axle 12 is fixed with braking rotating shaft 121, the other end is connected with extension spring 131; At least there is speed during simply lasting control arrowband conveying.
Silt form d is supported on supply roll 11 and carries, wherein supply roll 11 is motor shaft, the conveying of arrowband d1 on silt form d is controlled by the rotating speed of motor, because silt form d needs to stop in course of conveying, accelerate and uniform movement, in the process accelerated, simple use motor can complete, but when being retained at the uniform velocity by acceleration and being stopped, realize not only causing the load of motor coil excessive by the rotating speed of motor, and cannot stop in time, particularly in process at the uniform velocity, the rotating speed of motor and the surperficial arrowband d1 surface tension formed that is stretched of arrowband d1 are difficult to control, therefore install on motor shaft between brake plate 111 and brake body 122 by rubbing to realize the extension on d1 surface, arrowband, the tension force on d1 surface, arrowband is controlled by friction force, adopt the mode of pressing friction can ensure that the tension force on d1 surface, arrowband is in stable extended state all the time, use rotating speed when friction force and driven by motor supply roll 11 between brake plate 111 and brake body 122, realize simultaneously.
Friction force can avoid accelerating too fast, reduction of speed is too fast and the situation of arrowband d1 Capillary Instability in continuous running, this is avoided the single external force of driven by motor supply roll 11 to make motor load comparatively large and tension force situation rambunctious.
Adopt extension spring 131 upwards to pull brake axle 12, the pulling force of extension spring 131 is fixed, and ensures that between brake body 122 on brake axle 12 and brake plate 111, friction force remains at fixed value.Be no matter to accelerate or under deceleration regime, the speed that arrowband is transferred is in motion of translation state all the time, fundamentally avoids, motor accelerates or larger heavy handled situation of slowing down; When extension spring 131 pulling force is upwards adjustable, friction force between brake body 122 and brake plate 111 can be made to be in adjustable state, coordinate the acceleration of motor, at the uniform velocity, the tension force of decelerated movement when making d1 surface in arrowband flexible is more stable, complete the control lasting to arrowband d1 surface tension, hereafter be described in detail to the control of extension spring 131, be again not repeated.
As shown in Fig. 1 to 4, a kind of Work-feeding means of easily tore film, comprises the supply roll 11 carrying out rotating for supporting silt form d, and silt form d is that nylon tape or plastic strip clot are formed, and silt form d can the similar adhesive tape for using in daily life.
By fixedly sleeved on supply roll 11 for a volume silt form d, carried by the expansion of supply roll 11 couples of silt form d, silt form d launch time arrowband d1 along silt form d plane tangent and extend outward.
Preferably, supply roll 11 is cylindrical shape, can be also both ends be cylindrical S. A., to be merged by the output shaft of cylindrical end and motor or transmission realizes the rotation of supply roll 11, cylindrical end and the output shaft of motor can adopt the mode be fixedly connected with to carry out transmission, to realize at the uniform velocity, acceleration, the motion of translation such as deceleration.
The end of described supply roll 11 is fixed with brake plate 111, brake plate 111 is the fixedly sleeved friction lining in supply roll 11 end in center or brake facing, adopt the friction lining of disc of the prior art, wherein brake body 122 can be electromagnet or be friction shoe, to be contacted with both brake plates 111 by brake body 122 and rub, realize the braking to supply roll 11, in the application, solving technical matters important in prior art is adopt constant friction force to control surperficial expansion force when arrowband d1 runs.
The rotating speed of simple dependence motor realizes when arrowband d1 runs capillary constant, need the control system that complicated, comprise the capillary detection of arrowband d1, and the transmission of signal between the balance of motor speed and system, rely on prior art can realize the control of this tension force, but the detecting element of the system of complexity and various precision and feedback element, management and control is more numerous and wayward, is not suitable for large-area universal.
The bottom of described supply roll 11 is provided with brake axle 12, and described brake axle 12 is provided with the brake body 122 carrying out braking for contacting brake plate 111, and one end of described brake axle 12 is fixed with braking rotating shaft 121, the other end is connected with extension spring 131.
Braking rotating shaft 121 is fixed on wallboard or on other supports that can fix, upwards pulled by other end extension spring 131 pairs of brake axles 12 of brake axle 12, realize brake body 122 and the contact friction of both brake plates 111, extension spring 131 determines pressure during contact, and the larger friction force of pressure more i.e. the more larger friction force of extension spring 131 pulling force upwards.
The lower end of described extension spring 131 be fixedly connected on braking rotating shaft 121 left end, rotating shaft 121 is fixed on the right-hand member of brake axle 12, the upper end of extension spring 131 is fixedly connected with movable sleeving 14 in braking, fixed with other mobile objects by movable sleeving 14 or just can the pressure that the pulling force of extension spring 131 and brake body 122 contact with both brake plates 111 be controlled by the adjustment that movable sleeving 14 carries out sliding up and down.
Movable sleeving 14 can be the threaded nut of tool, is moved on bolt by nut, can realize movable sleeving 14 fixing at bolt diverse location.
