Abstract
The utility model discloses a device specially for detecting the length or the movement speed of a flexible ribbon, in particular to a double wheel coding speed measuring device which consists of a bottom cover and a housing. The housing is provided with an electronic encoder and an electronic frequency divider. A wheel shaft on the rear part of the housing is provided with a tachometer wheel. The operating principle of the product is as follows: the flexible ribbon drives the tachometer wheel to rotate; the electronic encoder is driven by the shaft wheel to work; the electronic encoder generates electrical pulse in proportion to the length or the operating speed of the flexible ribbon; the obtained information is processed in series by the electronic frequency divider; the detected result is reflected on an external displayer. The product has simple structure and reasonable design. As the product has a double wheel structure, the center of gravity is stable, the product is clung to the flexible ribbon and is not easy to be ejected by the flexible ribbon, and the detecting accuracy is guaranteed. The product is provided with the electronic encoder to be a detecting element, thereby solving the problems that the service life of a photocoupler is short, and a luminescent tube is easy to be adhered with dust and the detection accuracy is affected, therefore, the utility model is an ideal device for detecting the speed of the flexible ribbon.
Description
Technical field
What the utility model was announced is to be specifically designed to the length of detection flexible strip-like articles or the device of translational speed.Be specially a kind of dicycly coding speed measuring device.
Background technology
Employed flexible strip-like articles speed measuring device in production reality at present, a kind of is the monocycly structure, the detecting element of employing is the photoelectric coupling device.But its shortcoming is because adopt the single-wheel structure, its unbalance, easy run-off the straight when wheel turns and contact bad with zone face.Again because in light weight, along with the shake of flexibility band produce bullet from, cause that to detect effect bad.In addition, the detecting element that its adopts is low serviceable life, and the luminotron of this device adheres to dust easily, thereby reduces the sensitivity and the reliability of signal.The product that has again adopts the two-wheel structure, but its inner gear shift that adopts carries out the detection of ribbon length and speed, but because the gap of gear interlock also can influence accuracy of detection.The device that uses at present is not very desirable thus.
Summary of the invention
The purpose of this utility model provides a kind of steadily of centre of gravity and is difficult for run-off the straight and the dicycly coding speed measuring device of assurance accuracy of detection.To solve the practical problems that existing product exists.Structure of the present utility model is as shown in drawings: be made of bottom and shell.On the front end of shell, have the line outlet lead.There is bearing seat both sides, rear portion at shell, have bearing in the bearing seat.One wheel shaft is arranged in the bearing.Two ends at wheel shaft have fifth wheel.Have the connection gear at the middle part of wheel shaft.At the shell middle part one Lineside encoding unit is arranged.Have a scrambler to connect gear on the scrambler, Lineside encoding unit connects gear by scrambler and connects mutually with wheel shaft.One Active crossover device is arranged in the Lineside encoding unit front portion.The Active crossover device is connected with the line outlet lead with Lineside encoding unit respectively by lead, is connected with external display again.Using method of the present utility model is attached on the flexible strip-like articles, as conveying belt etc. with fifth wheel.Its principle of work is: when work, and the conveying belt because fifth wheel closely reclines, the two produces relative motion.Fifth wheel rotates, and drives Lineside encoding unit and rotates, and Lineside encoding unit produces the electric pulse that is directly proportional with flexible strip length or speed simultaneously, again through the seriation of Active crossover device.Detect the length and the speed of flexible band.This use new structure is simple, and is reasonable in design.Because be the two-wheel structure, have scrambler and Active crossover device in the body, make to recline product steadily of centre of gravity in use closely with flexible strip-like articles, not can because of flexibility band shake bullet from, improved accuracy of detection.In addition, adopt Lineside encoding unit, and will detect the DS processing, greatly improved accuracy of detection by the Active crossover device as detecting element.There is not the problem that causes accuracy of detection to reduce owing to dust adhesion.It is a kind of very good flexibility band speed measuring device.Solved the variety of issue that existing product exists.
