Abstract
The invention relates to a cotton layer thickness detection device based on capacitance changes. The cotton layer thickness detection device comprises capacitance pieces connected with a capacitance detection device. A capacitance medium is connected between the capacitance pieces in a sliding mode trough a slide rod. The lower end of the slide rod is fixedly connected with an arc-shaped piece. A spring is fixedly connected between the arc-shaped piece and the capacitance medium. The cotton layer thickness detection device has the advantages of being simple in structure, easy and convenient to operate, good in detection effect and high in accuracy.
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 cotton layer thickness checkout gear based on capacitance variations 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:
Based on a cotton layer thickness checkout gear for capacitance variations, 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 described arc-like sheet and capacitor dielectric.
It is simple that the present invention has structure, feature easy and simple to handle, Detection results good, the degree of accuracy is high.
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.
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.
Claims (1)
1. the cotton layer thickness checkout gear based on capacitance variations, it is characterized in that: comprise the capacitance sheet be connected with capacitance detecting device, capacitor dielectric is connected by sliding bar, the affixed arc-like sheet in lower end of slide bar, affixed spring between described arc-like sheet and capacitor dielectric between capacitance sheet.
