Belt speed measuring device

Abstract

The invention disclose a belt speed measuring device, which comprises a main shaft; wherein, the main shaft is provided with a coupling which is flexible connection, one side of the coupling is connected with a roller and the other side is provided with a speed measuring coder, the main shaft is also provided with a sleeve, the interior of which is provided with a pin roll, the surface of the roller is provided with a flower groove or an adhesive layer; the belt speed measuring device is mainly applied in the positions of an electronic belt scale, a constant weight feeder and the like which need real time speed measuring, can automatically adjust the slope angle with the belt, depends on self gravity to contact with the belt; the roller is provided with the flower groove or the adhesive layer, which can effectively prevent slipping and detects the true velocity of the belt; the flexible connection is adopted between the speed measuring coder and the roller, which guarantees the speed measuring coder not to be damaged, simultaneously ensures the synchronization with the roller and the accuracy and reliability of the speed measuring; the belt speed measuring device outputs standard pulse signals, can be switched in different control instruments or systems, is convenient to be installed, has high cost performance and accurate speed measuring and parts thereof do not need to be maintained.

Description

technical field [0001] The invention relates to a speed measuring device equipped with an electronic belt scale, in particular to a belt speed measuring device for detecting the speed of a belt conveyor. Background technique [0002] The speedometer is a special equipment equipped with the electronic belt scale. It is a device used to detect the speed of the belt conveyor. Its detection accuracy directly affects the accuracy of the electronic belt scale. The pulse signal generator installed at one end of the speed measuring drum for shaft head speed measurement is light in weight and often bounces when measuring the belt speed, resulting in inaccurate speed measurement.

[0002] The speedometer is a special equipment equipped with the electronic belt scale. It is a device used to detect the speed of the belt conveyor. Its detection accuracy directly affects the accuracy of the electronic belt scale. The pulse signal generator installed at one end of the speed measuring drum for shaft head speed measurement is light in weight and often bounces when measuring the belt speed, resulting in inaccurate speed measurement. In addition, the vibration of the belt and the bonded materials seriously affect the measurement accuracy and accuracy of the electronic belt scale. reliability

[0003] Most of the traditional belt speedometers use multi-stage gear transmission. Due to the large number of gears and the large meshing gap, the belt speed measurement is inaccurate, and even the counting data is lost, and the manufacturing cost is high; the two friction wheels used for speed measurement are installed on the same On the shaft, due to the vibration generated by the belt drive, the friction wheel will be bumped up, so that the data will be lost, and even the speed cannot be measured.

[0004] The existing connection device between the speed sensor of the electronic belt scale and the fixed shaft of the belt tail wheel is to add a connecting shaft with a smaller diameter at one end of the fixed shaft of the belt tail wheel, and then connect the connecting shaft with the drive shaft of the speed measuring sensor through a cylindrical joint Together, the middle of the cylindrical joint is provided with a channel for inserting the connecting shaft and the transmission shaft of the speed measuring sensor, and a screw hole is provided on one side for fastening the connecting shaft and the transmission shaft of the speed measuring sensor. This connecting device is not only structural Complicated and short-lived
