2, simple in structure.
3, easy for installation, matching is good.Because the technical program is to carry out improvement and design on the special tubaeform sliver input end head standard component of carding machine, do not change existing installations, matching is good, and easy for installation.
4, good reliability, does not need frequent cleaning, easy to maintenance.
5, realize fast the online detection of industry spot.
6, microwave emissive power is very little, and scattering microwave when work is pollution-free to environment and human body, safe.
Brief description of the drawings
Fig. 1 is the structural representation of the present embodiment.
Fig. 2 is microwave testing functional-block diagram in the present embodiment.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in Figure 1, the present embodiment comprises the special sliver input termination 9 of carding machine, microwave cavity 4, microwave signal generator assembly 8, emitting probe 1, receives probe 6, microwave signal detector arrangement assembly 11, described microwave cavity 4 is located at described sliver input 9 exits, termination, in described microwave cavity, 4 are provided with sliver output channel 2, and described emitting probe 1 and reception probe 6 are located in described microwave cavity 4.
Described microwave cavity 4 comprises resonant cavity 5, cover plate 7 and airtight spacer sleeve 3, described airtight spacer sleeve 3 is located in resonant cavity 5, described microwave cavity 4 is isolated into ring texture, described airtight spacer sleeve 3 one end are connected with described sliver input termination 9 outlets, described airtight spacer sleeve 3 other ends are connected with described resonant cavity 5 outlets, described cover plate 7 seals the described microwave cavity 4 of ring-type, described emitting probe 1 and to receive probe 6 symmetrical and be fixed on described cover plate 7.
Described airtight spacer sleeve 3 adopts nonmetal medium material, and described nonmetal medium material is teflon.In a word, it is closed structure that described airtight spacer sleeve 3 uses polytetrafluoroethylmaterial material and surrounding structure, while making sliver pass microwave cavity on the one hand, avoid the obstruction of cotton-wool to microwave cavity, meanwhile, do not affect again the resonance of resonator cavity, can efficiently transmit again on the other hand microwave energy, reduce the loss of medium to microwave energy, ensured the microwave electromagnetic field energy of microwave cavity.
As shown in Figure 1 and Figure 2, when sliver is produced, the microwave signal that microwave signal generator produces is sent to microwave cavity by emitting probe (1), produces microwave electromagnetic field energy in microwave cavity.When sliver 10 continuous by airtight spacer sleeve 3, during fast through microwave cavity, different densities and the sliver with certain water percentage can cause microwave electromagnetic field energy parameter change (cavity resonant frequency skew resonant cavity quality factor Q value occurs and changes), receive probe 6 and send microwave electromagnetic field energy variation situation to microwave signal detector arrangement, microwave signal detector arrangement is by the detection to its energy parameter variable quantity, analyze, and the processing of signal conversion processes device, thereby obtain the 0-10V signal output corresponding with the data of sliver different densities.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model know-why; can also make some improvement and distortion, these improvement and distortion also should be considered as protection domain of the present utility model.
