Detailed Description
In the following, an embodiment of the present invention will be described in detail with reference to the drawings, but it should be understood that the scope of the present invention is not limited by the embodiment.
As shown in fig. 1 to 4, an embodiment of the present invention provides a roller tension sensor, including:
the strain gauge comprises an elastic element body 1, wherein parallel beams are arranged on the upper side and the lower side of the elastic element body 1, a plurality of strain gauges 2 are arranged on the parallel beams, the strain gauges 2 are elements for measuring strain and are formed by sensitive grids and the like, the working principle of the strain gauges 2 is manufactured based on a strain effect, and the strain effect is that when a conductor or a semiconductor material is mechanically deformed under the action of external force, the resistance value of the conductor or the semiconductor material is correspondingly changed; and
one end of the force measuring shaft 3 is fixedly connected with one end of the elastic element body 1, a guide roller 4 is installed on the force measuring shaft 3, and a part of the guide roller 4 is sleeved on the elastic element body 1;
the utility model discloses make a sensor with the roller, namely assemble a tension sensor directly to the roller, because the roller rotates at high speed always in the in-service use process, to only adorning a sensor like this, the antidetonation of sensor and anti unbalance loading ability need be strong, further, as shown in fig. 4, fretwork groove 5 has all been seted up to the upside and the downside of elastic element body 1, fixedly connected with three in fretwork groove 5 the parallel beam, three the parallel beam be girder 6 and lie in two auxiliary beams 7 of girder 6 both sides respectively, the both ends department of girder 6 all installs foil gage 2;
the strain gauge 2 is attached to the main beam 6, so that the stress of the elastic element body 1 can be detected, and the two auxiliary beams 7 play a role in protecting the main beam 6 and playing a decisive role in resisting vibration and unbalance loading of the sensor;
the sensor also comprises an installation flange 8, wherein the installation flange 8 is fixedly connected to one end of the elastic element body 1, which is far away from the force measuring shaft 3, so that the whole sensor can be conveniently fixed;
still include cable plug 9, cable plug 9 with elastic component body 1 fixed connection installs the PCB board in the elastic component body 1, and a plurality of foil gauges 2 all are connected with the PCB board electricity, and cable plug 9 is used for connecting tension controller, plays signal transmission's effect.
Further, two bearings 10 are installed on the force measuring shaft 3, and the guide roller 4 is installed on the two bearings 10.
The working principle is as follows: during measurement, an external force is applied to the guide roller 4, the force on the guide roller 4 is transmitted to the elastic element body 1, the elastic element body 1 generates certain deformation, the resistance of the strain gauge 2 changes due to extrusion generated by deformation of the elastic element body 1, and the tension controller detects the tension through the resistance variation of the strain gauge 2.
It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
