A kind of crawler type meter-measuring device
Technical field
The present invention relates to a kind of length metering device, particularly a kind of material that can be used for having continuous length to cable etc.
Carry out the long meter-measuring device of meter.
Background technology
All exist during the producing and selling and use in the fields such as printing, compound, cutting and coiling to the accurate meter of length
The demand of amount, current common metering method is that, using meter counter metering, the degree of accuracy of meter counter metering will directly affect line
The accuracy of the gauging of products such as cable.
Conventional mechanical meter counter has two kinds of wheel-type Meter coun ter and crawler type meter counter, wherein, wheel-type Meter coun ter is utilized
Contact roller extruding cable make between cable and measurement wheel produce frictional force after be synchronized with the movement so that by measurement wheel girth and turn
Moving-coil number carries out metering, and because measurement wheel and the tested cable of wheel-type Meter coun ter are that point is contacted, frictional force therebetween is smaller,
Generation skidding, i.e. synchronism are easy in measurement process poor, and measurement wheel also easily abrasion in use,
These can all make wheel-type Meter coun ter produce larger error of meter counter in actually measurement.Chinese patent literature CN101625226A is public
A kind of mechanical meter counter, namely crawler type meter counter are opened, it utilizes above and below four synchronous pulleys two-by-two one group of composition two
Individual ring-shaped synchronous belt mechanism, two synchronous belt mechanisms is clamped tested cable using hold-down mechanism makes cable keep synchronous fortune therewith
Although dynamic and then survey length, the meter counter has used timing belt, has increased the contact area with cable, but due to taking turns it positioned at two pairs
Between the contact-segment part being in contact with tested cable be it is hanging, actually measurement in, the part is seemed closely to be connect with cable
Touch, but its normal pressure acted on cable is then very little, its size to cable normal pressure depends on the tension force of timing belt
And the clamping force of upper and lower synchronous belt mechanism, so contact-segment part is far away from upper and lower belt wheel to the normal pressure size one of cable
To the normal pressure of cable, two be easily to be influenceed and changed by factors such as shakes in device abrasion and measurement process, is caused
The frictional force between timing belt and tested article in measurement process is unstable, and then synchronism is unstable causes error of meter counter;Separately
Outside, the crawler type meter counter is to the normal pressure opposing pulleys of cable to the normal pressure of cable due to differing greatly contact-segment part,
The working effect of upper and lower synchronous belt mechanism be substantially equivalent to timing belt on two groups of outer layer covers to taking turns in synchronous working, i.e.,
Equivalent to being that two points are contacted with tested cable, although so the relative wheel-type Meter coun ter of existing crawler type meter counter is in error of meter counter
On make moderate progress, but the defects such as skidding, shake are equally existed, especially for process cable, due to being located at correspondence thereon
High point on bus is interrupted, and skidding jitter phenomenon will become more apparent frequently, and it is unstable to thereby result in synchronism, misses metering
Difference is bigger than normal.
