Abstract
The invention relates to a capacitance type cotton layer thickness detecting device with a safety limiting function. The capacitance type cotton layer thickness detecting device comprises capacitor pieces connected with a capacitance detecting device, a capacitor dielectric is connected between the capacitor pieces in a sliding mode through a sliding rod, an arc piece is fixedly connected to the lower end of the sliding rod, and a spring is fixedly connected between the arc piece and the capacitor dielectric; a proximity switch is further arranged between the capacitor pieces and located above the capacitor dielectric, and the proximity switch is connected with a control unit. The capacitance type cotton layer thickness detecting device with the safety limiting function has the advantages that the structure is simple, operation is convenient, the detecting effect is good, accuracy is high, and detection is safe.
Description
Technical field
The present invention relates to field of textile machinery, particularly relate to evereven field.
Background technology
Evereven is a vitals of textile machine, it can by the change of the thickness of cotton layer adjust feed roll motor to cotton speed, thus make to keep certain to cotton amount in the feed roll motor unit interval.Current evereven adopts mechanical balance adjust structure usually, and volume is large, Heavy Weight, complex structure, particularly this structure are fed cotton layer has very large hysteresis quality to the even adjustment of amount.
Content of the present invention
The applicant is for the baroque problem of existing evereven, carry out linguistic term, a kind of condenser type cotton layer thickness checkout gear with safe spacing is provided, the varied in thickness of cotton layer can be directly changed into the signal of telecommunication by it, then be transferred to control unit, there is response time short, highly sensitive advantage.
Technical scheme of the present invention is as follows:
With a condenser type cotton layer thickness checkout gear for safe spacing, comprise the capacitance sheet be connected with capacitance detecting device, between capacitance sheet, connect capacitor dielectric by sliding bar, the affixed arc-like sheet in lower end of slide bar, affixed spring between arc-like sheet and capacitor dielectric; Between the capacitance sheet of the top of capacitor dielectric, be also provided with proximity switch, proximity switch is connected with control unit.
It is simple that the present invention has structure, feature easy and simple to handle, Detection results good, the degree of accuracy is high and detection is safe.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As shown in Figure 1, the present invention includes the capacitance sheet 2 be connected with capacitance detecting device 5, the affixed arc-like sheet 4 in lower end of be slidably connected by slide bar 3 between capacitance sheet 2 capacitor dielectric 6, slide bar 3, affixed spring 1 between described arc-like sheet 4 and capacitor dielectric 6; Between the capacitance sheet 2 of the top of capacitor dielectric 6, be also provided with proximity switch 8, proximity switch 8 is connected with control unit.
Working method of the present invention is as follows:
Cotton layer enters apparatus of the present invention from left to right along feeding plate 7, and the extruding that arc-like sheet 4 is subject to cotton layer upwardly capacitor dielectric 6 is risen; In uneven thickness due to cotton layer, the height that capacitor dielectric 6 rises is also inconsistent, and the height that capacitor dielectric 6 rises makes DIELECTRIC CONSTANT ε change, and then causes capacitance to change; Detect this change by capacitance detecting device 5, just can obtain the change of cotton layer thickness.When the thickness of cotton layer is too thick, capacitor dielectric 6 rises to the position exceeded between capacitance sheet 2, and touching proximity switch 8. proximity switch 8 stops weaving loom work by control unit.
