Embodiment 1

[0052] A voltage-type tape running speed and slip detection device is composed of a fixed column 1, a tension spring 2, a movable arm 3, a transmission shaft 4, a passive friction wheel 5, a voltage-type detection unit 7 and an alarm device. The fixed column 1 Fixedly connected on the tape machine frame 6, the middle part of the fixed column 1 is hinged with one end of the movable arm 3, one end of the tension spring 2 is fixed at the bottom of the fixed column 1, and the other end is fixed at the middle part of the movable arm 3, and the passive friction The wheel 5 is connected to the other end of the movable arm 3 through the transmission shaft 4, and the passive friction wheel 5 is in frictional contact with the tape, and the voltage detection unit 7 is fixedly connected to the movable arm 3, and is fixedly connected to one end of the transmission shaft 4;

[0053]Described voltage detection unit is made up of box body 71, active large gear 72, passive pinion 73, generator ...

Embodiment 2

[0056] A method for detecting the running speed of an adhesive tape, using the voltage-type adhesive tape running speed and slip detection device of Embodiment 1, comprising the following steps:

[0057] 1) Turn on the tape machine and the detection device, and the host computer receives the voltage signal from the generator in the device;

[0058] 2) The upper computer calculates the actual running speed of the tape of the tape machine according to formula 5;

[0059] The calculation principle is:

[0060] The tape to be monitored is in close contact with the passive friction wheel in the device, and is driven by friction, so the actual running speed of the tape is S 胶 The linear speed S of the contact point between the passive friction wheel and the tape 线 equal, according to the radius R of the passive friction wheel 摩 The speed N of the passive friction wheel can be calculated 摩 ,which is:

[0061] S 胶 = S 线 =0.002πR 摩 N 摩 (1)

[0062] In the formula, S 胶 : The...

Embodiment 3

[0082] A method for detecting tape slippage, using the voltage-type tape running speed and slip detection device of embodiment 1, comprising the steps of:

[0083] 1) Set the running speed of the tape machine during normal operation in the upper computer, and receive the voltage signal sent by the generator in the device;

[0084] 2) Use the host computer to monitor the actual running speed of the tape corresponding to the received voltage signal and set the running speed of the tape;

[0085] 3) Monitoring alarm

[0086] When the tape frequency is running:

[0087] When the running speed of the tape is lower than 95% of the rated speed of the tape, it means that the tape is slipping, and the upper computer notifies the alarm device to alarm;

[0088] When the tape frequency is running:

[0089] When the running speed of the tape is lower than 95% of the given speed of the tape, it means that the tape is slipping, and the upper computer notifies the alarm device to alarm.

Abstract

The invention aims to solve the problem that in the prior art, the adhesive tape running speed and the slip detection are inaccurate, and provides a voltage type adhesive tape running speed and slip detection device and a detection method. The device is composed of a fixing column, a tension spring, a movable arm, a transmission shaft, a passive friction wheel and a voltage type detection unit, wherein the fixing column is fixedly connected to a machine frame of an adhesive tape machine, the middle of the fixing column is hinged to one end of the movable arm, one end of the tension spring is fixed to the lower portion of the fixing column, the other end of the tension spring is fixed to the middle of the movable arm, the passive friction wheel is connected to the other end of the movable arm through the transmission shaft, the passive friction wheel is in frictional contact with the inner surface of an adhesive tape, the voltage type detection unit is fixedly connected to the movable arm, and is fixedly connected with one end of the transmission shaft. The device has the advantages that the speed of the adhesive tape is directly measured, the influence of slipping between a rollerand the adhesive tape on the speed of the adhesive tape is avoided, and the speed of the adhesive tape measured by the device is true and reliable.

Description

technical field [0001] The invention belongs to the technical field of belt machine operation detection, and in particular relates to a voltage-type belt running speed and slip detection device and detection method. Background technique [0002] With the continuous improvement of the level of industrial automation, the application of belt conveyors is becoming more and more extensive, and the requirements for its operation and detection are also getting higher and higher, especially in the field of metallurgical iron, almost all materials are transported by belt conveyors. And in order to ensure the reliability of the operation of the belt conveyor, almost every belt conveyor has a running speed and slip detection device. However, there are still a series of problems in the detection of the running speed and slippage of the tape machine in the prior art in terms of accuracy and scope of application. The speed of the tail drum is used as the running speed of the tape of the ...
