Abstract
The invention discloses a thickness detection device of an auto-leveling device. The thickness detection device of the auto-leveling device comprises a sliding rail connected with a machine frame, a sliding block is arranged on the sliding rail, one end of a leaf spring is hinged to the sliding block, the other end of the leaf spring is connected with the machine frame, and an upper capacitor plate and a lower capacitor plate are arranged on the upper side and the lower side of the sliding block respectively and are respectively connected with a capacitor detection device. The thickness detection device of the auto-leveling device can directly convert thickness changes of a cotton layer into electrical signals, the electrical signals are transmitted to a control unit, and the thickness detection device of the auto-leveling device has the advantages of being short in response time and high in sensitivity.
Description
Technical field
The present invention relates to field of textile machinery, relate in particular to evereven field.
Background technology
Evereven is a vitals of textile machine, it can change by the thickness of cotton layer to adjust to cotton roller to cotton speed, thereby make to cotton roller to cotton amount, to keep certain in the unit interval.Current evereven adopts mechanical balance to adjust structure conventionally, and the even adjustment that volume is large, Heavy Weight, complex structure, particularly this structure are fed to amount cotton layer has very large hysteresis quality.
Content of the present invention
The applicant is for the baroque problem of existing evereven, improve research, a kind of thickness detection apparatus of evereven is provided, it can be directly changed into the signal of telecommunication by the varied in thickness of cotton layer, then be transferred to control module, have advantages of that the response time is short, highly sensitive.
Technical scheme of the present invention is as follows:
A thickness detection apparatus for evereven, comprises the slide rail being connected with frame, and on described slide rail, device has slide block; One end of spring leaf is articulated with on described slide block, and the other end is connected with described frame; The upper and lower sides of described slide block is respectively equipped with capacitor board and lower capacitor board, and described upper capacitor board is connected with capacitance detecting device respectively with lower capacitor board.
Beneficial effect of the present invention is: because the thickness of cotton layer is also inhomogeneous, spring leaf constantly deforms under the effect of surface layer, thereby band movable slider moves; Upper capacitor board and lower capacitor board form the two-plate of electric capacity, and the movement of slide block can make the dielectric constant between two-plate change, and then causes capacitance to change; By capacitance detecting device, detect this variation, just can obtain the thickness of cotton layer.
The varied in thickness of cotton layer can be directly reflected as the variation of capacitance, and generally speaking the transmission speed of the signal of telecommunication and processing speed are all fast than mechanical signal, thereby response speed of the present invention is very fast; Simultaneously from mathematical derivation, under the condition of given one section of arc length, the variable quantity of chord length is greater than the variable quantity of its radius of curvature, thereby the variation of the displacement of slide block (being equivalent to chord length) has amplification to the variation of cotton layer thickness (being equivalent to radius of curvature), the sensitivity of checkout gear is improved.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The specific embodiment
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 slide rail 2 being connected with frame 1, on slide rail 2, device has slide block 3; One end of spring leaf 7 is articulated with on slide block 3, and the other end is connected with frame 1; The upper and lower sides of slide block 3 is respectively equipped with capacitor board 4 and lower capacitor board 6, and upper capacitor board 4 is connected with capacitance detecting device 5 respectively with lower capacitor board 6; Cotton layer enters apparatus of the present invention along the direction of arrow.
Working method of the present invention is as follows:
Cotton layer enters apparatus of the present invention from left to right along feeding plate 8, and the extruding that spring leaf 7 the is subject to cotton layer deformation that makes progress, promotes slide block 3 and move right; In uneven thickness due to cotton layer, slide block 3 can move left and right.Upper capacitor board 4 and lower capacitor board 6 form the two-plate of electric capacity, and the movement of slide block 3 can make the DIELECTRIC CONSTANT ε between two-plate change, and then causes capacitance to change; By capacitance detecting device 5, detect this variation, just can obtain the variation of cotton layer thickness.
The present invention changes cotton layer thickness to convert to after the change in displacement of slide block 3, can transmit and process relevant change information by the signal of telecommunication, compares existing mechanical type regulator, and response speed improves greatly; In addition by mathematical formulae, can be pushed over out: under the certain condition of arc length (length of spring leaf 7 is constant), the variable quantity of chord length (distance that slide block 3 moves left and right) is greater than the variable quantity (deformation that spring leaf 7 causes due to surface thickness variation of its radius of curvature, be equivalent to make the radius of curvature of spring leaf 7 that variation has occurred), thereby the variable quantity of the amount of movement opposite face layer thickness of slide block has amplification, the sensitivity of detection is higher.
More than describing is explanation of the invention, is not limitation of the present invention, and limited range of the present invention is referring to claim.Without departing from the basic structure of the case in the present invention, the present invention can do any type of modification.
