Background technology
In disposable sanitary articles field, the field of full-automatic production is gradually stepped into the automation of production equipment.One It is inevitably because various in board operational process in the manufacturing of secondary sex hygiene articles for use production equipment Extraneous factor causes material tensile force to change, and ensures that the stabilization of material tensile force is that the first of product quality ensures.Therefore equipment Ensure material feeding in operation to compound, or even to during production completion, tensile force is stably held in setting value model Importance in enclosing is self-evident.Or existing material tension controls, too simple, controllability is smaller or excessively complicated, Precision is higher to cause cost also higher.
China Patent No.:201410600667.5 a kind of tenslator is disclosed, for controlling by sheet material Power, including:Driving portion, including driven roller, mip rolls, driven roller driving part and mip rolls driving part, the driven roller Driving part is connect with driven roller, and the mip rolls driving part is connected with mip rolls, and the mip rolls driving part is located at The top of mip rolls, the axis of the mip rolls is parallel with the axis of driven roller, the axis of the mip rolls and the axis of driven roller Plane and horizontal plane formed by line;Tension force portion, including block part, induction component, swing rod, adjusting deflector roll and adjustment portion Part, the longitudinally of the swing rod is vertical with the axis of the driven roller, and described one end for adjusting deflector roll and the swing rod are servo-actuated Side one end is connected, and the roll axial direction for adjusting deflector roll is vertical with the longitudinally of swing rod, and the adjusting deflector roll is located at described The downstream of driving portion, and positioned at the upstream of the output section, the block part is connected with the other end of swing rod, the induction part Part be located at block part and adjust deflector roll between, the induction component include at least one fulcrum shaft, one end of the fulcrum shaft and Swing rod connect, the axis direction of fulcrum shaft is vertical with swing rod longitudinally, the induction component also comprising signal conversion part with Connector, the fulcrum shaft are connect by connector with the signal conversion part;Output section, including at least one output is led Roller.The operation principle of the device is:When material is in transmission process, when tension changes, swing rod surrounds the fulcrum shaft Center line is swung, and fulcrum shaft is rotated in the case where the swing of swing rod drives at this time, and fulcrum shaft rotational motion parameter is transmitted by connector To the signal conversion part, the fulcrum shaft rotational motion parameter is converted to digital signal by signal conversion part, and by the number Word signal feeds back to the central processing unit of device motion control, and the central processing unit of motion control upon receipt of the signals, and is incited somebody to action Signal transmission gives the driven roller driving part, driven roller driving part to receive the rotary speed of change driven roller after signal, To change material to adjusting the active force of deflector roll, the upper end of regulating member sets back, and swing rod restores balance state again, rises To adjustment effect;But incude the transformation of the Zhang Jinli of component moment monitoring material, by the central processing unit moment to driven roller Speed be finely adjusted, it is excessively complicated, precision is higher causes cost also higher.
Utility model content
Therefore, for above-mentioned problem, the utility model provides a kind of tenslator, it mainly solves existing skill Tenslator is excessively complicated in art, precision is higher leads to cost also higher problem.
To achieve the above object, the utility model uses following technical scheme:A kind of tenslator, including machine Frame is respectively arranged with motor, deflector roll and the control of let off roll, wind-up roll, driving let off roll and wind-up roll rotation in the rack Device processed, the side that deflector roll is located in the rack are provided with tensioning force control device, and the control device includes rotationally setting The shaft in rack is set, is fixed with swing rod in the shaft, rotatably arranged with there is supporting rack on the free end of the swing rod, Be provided at least one regulating roller on support frame as described above, each regulating roller is distributed in the side of deflector roll, in the rack with turn Axis connection is provided with rotary encoder, and the encoder and motor are electrically connected with the controller respectively.
Further, it is additionally provided with first gear in the shaft, shaft side is provided with rotation in the rack Axis is provided with the second gear engaged with first gear in the rotary shaft, is set positioned at second gear side in the rotary shaft It is equipped with brake pad, spring is arranged in the rotary shaft, the brake pad is resisted against on spring.
Further, it is provided with external screw thread in the rotary shaft, is located in the rotary shaft at external screw thread and is threaded with The other end of adjusting nut, the spring is resisted against on adjusting nut.
Further, the number of the regulating roller is two.
Further, two regulating rollers are horizontally disposed in the same plane.
By using preceding solution, the utility model has the beneficial effects that:This tenslator passes through setting Clamp force control device prevents material caused by a variety of causes in transmission process to control the tensile force in material transmission process Fracture, in transmission process, material bypasses deflector roll and regulating roller respectively, when the slight tension of material, to increase material With the pulling force of regulating roller so that supporting rack rotates certain angle on swing rod, and then adjusts the tensile force of material, when material Tightening force increases, and swing rod is connected with the rotating shaft rotary encoder in the pulling force effect lower swing of material to drive shaft to rotate Signal is received, controller is transported to, the rotation of motor is controlled by controller, and then adjust the tensile force of material, played The effect of automatic fine tuning, reduces the precision of device, to reduce production cost;Further, it is arranged on the rotary shaft Spring pushes brake pad to be resisted against second gear side, increases its frictional force, what the drive shaft to increase shaft rotated Torsion, the size of tensile force when to control device fine tuning, and then reduce the precision of device;Further, pass through adjusting Rotating nuts, to the compression travel of adjustment spring so that the frictional force between brake pad and second gear changes, to Tensile force of the different materials in transmission process is adapted to adjust.
