Abstract
An automatic tightness regulator for a wire cutting wire feeding barrel belt comprises two transition belt wheels which are installed to be tangent to the belt, a driving device, a sensor used for detecting the tightness changes of the belt and a control unit used for receiving a sensor signal and controlling the driving device to work. A belt tightness control method comprises the following steps that a reference value is preset on the control unit; the sensor collects the tightness of the belt and transmits the tightness to the control unit, and the control unit converts the tightness of the belt into a comparison value; the comparison value and the preset reference value are calculated to obtain a difference value; the difference value is calculated through an internal adaptive algorithm to obtain a driving value; if the driving value is larger than zero, the control unit drives a motor to anticlockwise rotate, and if the driving value is smaller than zero, the control unit drives the motor to clockwise rotate; the above steps are repeated until the driving value is zero.

The present invention solves the problems of the technologies described above taked technical measures: a kind of Linear cut wire transporting cylinder belt tension automatic regulator, comprise two transition belt pulleys, also comprise a drive unit, one for detecting the sensor of belt tightness degree change, also comprise a control unit, described control unit sensor-lodging accessory drive work.
The screw rod that described drive unit comprises two guide pillars be parallel to each other and is arranged between guide pillar, one end of described screw rod arranges the motor for driving described bolt rotary, sheathed sliding seat on described guide pillar and screw rod, it is secondary that described screw rod and sliding seat form screw-driven, described guide pillar forms rolling friction pair by linear bearing and sliding seat, described sliding seat plane arranges supporting seat, described supporting seat to be matched with described sliding seat by screw and installs, described supporting seat is arranged transition belt pulley, in described transition belt pulley, bearing is set, described bearing to be matched with described supporting seat by nut and installs.The upper end of described motor arranges an angle bar, described angle bar one end arranges two U-shaped elongated holes, described angle bar is arranged on fixed head that described motor is arranged by screw, the other end of described angle bar and upper described sensor are matched by screw and install, described covers disposed on sensor puts a supporting seat, supporting seat arranges bearing, bearing is arranged transition belt pulley, described bearing matches with transition belt pulley and installs.Said apparatus is arranged in the belt pulley space of wire transporting cylinder, the tangent installation of belt in upper described two transition belt pulleys and wire transporting cylinder.
During work, utilize the U-shaped elongated hole that angle bar is arranged, adjust the optimum distance of sensor sensing belt tightness degree, preset an a reference value on the control unit, sensor detection belt tightness degree also forms a fiducial value, fiducial value and a reference value are compared, according to the result that above-mentioned comparison step obtains, make drive unit drive upper described in be arranged on transition belt pulley slippage in sliding seat for adjusting the elasticity of belt.
Present invention also offers a kind of control method of belt tightness degree, comprise the steps: that (1) presets an a reference value on described control unit; (2) sensor gathers the elasticity of belt and datumization and reach on control unit; (3) belt tightness degree collected in described step 2 is converted into fiducial value by control unit; (4) in the fiducial value described step 3 obtained and described step 1, default standard value calculates; Thus obtained difference obtains a motivation value by inner adaptive algorithm; (5) if motivation value is greater than zero, then control unit drive motors is rotated counterclockwise, if motivation value is less than zero, then control unit drive motors turns clockwise; (6) above-mentioned steps is repeated, until described motivation value is zero.
The invention has the beneficial effects as follows: the present invention automatically can adjust the elasticity of belt and make the elasticity of belt be stabilized in a quantifiable scope, stablize the jitter range of wire transporting cylinder, simple to operate, the pulley drive wire transporting cylinder of different model wire cutting machine can be applicable to, improve precision, the surface smoothness of processing work, reduce molybdenum wire breakage rate, increase work efficiency.
