Abstract
The utility model discloses a kind of speed measuring device of constant feeder; including rotary encoder; the rotary encoder is fixedly connected by elastic coupling with driven pulley; described elastic coupling one end aperture is 15mm; and elastic coupling other end aperture is 8mm, a diameter of 15mm in shaft end of the driven pulley, described rotary encoder one end is provided with elastic support; and elastic support is fixedly connected with driven pulley, containment vessel is provided with the outside of the rotary encoder encoder.The speed measuring device of the constant feeder, by the way that on the driven wheel, when driven pulley rotates, rotary encoder can follow driven pulley run-in synchronism, therefore the speed that rotary encoder is measured is real belt speed by rotary encoder installation.
Description
Technical field
The utility model belongs to speed measuring device technical field, and in particular to a kind of speed measuring device of constant feeder.
Background technology
Constant feeder is that one kind is bulk materials（Bulk, particle, powdery etc.）Continuous weighing metering is simultaneous quantitative defeated
The plant equipment sent, it is the ideal equipment that consecutive weighings feed is carried out to bulk material, is widely used in cement, mine, builds
The industries such as material, grain, chemical industry.As a kind of critically important dynamic measuring instrument, its production to enterprise has constant feeder
Very important effect.But but there are some defects in traditional constant feeder.If traditional constant feeder is logical mostly
The output frequency of detection frequency converter or the rotating speed of original motor are crossed, extrapolates the speed of conveyer belt.The drawbacks of so doing one be if
Conveyer belt is too tight or too loose, or conveyer belt on the inside of get stuck, caused by conveyer belt shake, skid etc.；Using detection frequency converter
The method of the rotating speed of output frequency or original motor, the speed measured are falsities, have had a strong impact on the accurate measurement of constant feeder
Degree.Second, output torque reduces when frequency converter low speed is run, now there is linear distortion in output frequency and given frequency；Using inspection
The method for surveying the output frequency of frequency converter or the rotating speed of original motor, the speed linearity distortion measured, has had a strong impact on dosing
The metering linearity of machine.Therefore a kind of speed measuring device that can detect real conveying tape speed is now needed to solve above-mentioned ask
Topic.
Utility model content
The purpose of this utility model is to provide a kind of speed measuring device of constant feeder, to solve in above-mentioned background technology
The problem of proposition.
To achieve the above object, the utility model provides following technical scheme：A kind of speed measuring device of constant feeder, bag
Rotary encoder is included, the rotary encoder is fixedly connected by elastic coupling with driven pulley, described elastic coupling one end
Aperture is 15mm, and elastic coupling other end aperture is 8mm, a diameter of 15mm in shaft end of the driven pulley, and the rotation is compiled
Code device one end is provided with elastic support, and elastic support is fixedly connected with driven pulley, and containment vessel is provided with the outside of the rotary encoder.
Preferably, the elastic support is provided with fixed fixing hole.
Preferably, the containment vessel side is provided with the opening to match with rotary encoder.
Technique effect of the present utility model and advantage：The speed measuring device of the constant feeder, by the way that rotary encoder is pacified
On the driven wheel, when driven pulley rotates, rotary encoder can follow driven pulley run-in synchronism to dress, therefore rotary encoder is measured
Speed be real conveying tape speed.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is top view of the present utility model.
In figure：1 rotary encoder, 2 elastic couplings, 3 driven pulleys, 4 elastic supports, 41 fixing holes, 5 containment vessels, 6 are opened
Mouthful.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
The utility model provides a kind of speed measuring device of constant feeder as shown in Figure 1-2, including rotary encoder,
The rotary encoder 1 is fixedly connected by elastic coupling 2 with driven pulley 3, and one end aperture of elastic coupling 2 is
15mm, and the other end aperture of elastic coupling 2 is 8mm, a diameter of 15mm in shaft end of the driven pulley 3, the rotary encoder 1
One end is provided with elastic support 4, and elastic support 4 is fixedly connected with driven pulley 3, and the outside of rotary encoder 1 is provided with containment vessel
5。
Further, the elastic support 4 is provided with fixed fixing hole 41.It is easy to elastic support 4 solid with driven pulley 3
Fixed connection.
Further, the side of containment vessel 5 is provided with the opening 6 to match with rotary encoder 1.Rotation is easily installed to compile
Code device 1.
Operation principle：The speed measuring device is directly installed on driven pulley 3, when driven pulley 3 rotates rotary encoder 1 with from
The run-in synchronism of driving wheel 3, the speed so measured are the speed of real conveyer belt.Rotary encoder 1 by elastic coupling 2 with
Driven pulley 3 connects, and elastic coupling 2 can effectively absorb outside axial force, protects rotary encoder 1.Rotary encoder 1 passes through bullet
Property support 4 be fixedly connected with driven pulley 3, elastic support 4 can effectively absorb outer radial power, protect rotary encoder 1.Containment vessel
5 can protect rotary encoder 1 in transport or not suffer damage when safeguarding.
Finally it should be noted that：Preferred embodiment of the present utility model is the foregoing is only, is not limited to this
Utility model, although the utility model is described in detail with reference to the foregoing embodiments, for those skilled in the art
For, it can still modify to the technical scheme described in foregoing embodiments, or to which part technical characteristic
Progress equivalent substitution, all within the spirit and principles of the utility model, any modification, equivalent substitution and improvements made etc.,
It should be included within the scope of protection of the utility model.
