The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further explain.
Like Fig. 1-shown in Figure 3, present embodiment comprises the special-purpose sliver input termination 13 of carding machine, displacement transducer 8, displacement transducer mount pad 6, spring 18, detects lever 12 and detect the lever manual overvide, wherein:
On said sliver input termination 13, have the U-lag 20 that communicates with the termination outlet; Said detection lever 12 is arranged in the described U-lag 20; The shaft of said detection lever 12 rotates with said sliver input termination 13 and connects; Like Fig. 4, shown in Figure 3, described rotation connection is made up of turning cylinder 23, bearing 22 and cover plate 10, and said turning cylinder 23 passes the shaft of said detection lever 12; Said turning cylinder 23 two ends and bearing 22 link, and bearing 22 is fixed on the said sliver input termination 13 by cover plate 10.
The lower end 14 of said detection lever is positioned at the sliver outlet plenum of sliver input termination 13; The lower end 14 of said detection lever is pressed on the sliver 26, and during work, the work intensity that the induction sliver flows changes; The upper end 17 of said detection lever withstands on the said spring 18; Said spring 18 other ends withstand on the spring base 19 of said sliver input termination 13, and said spring base 19 be a set screw, make set screw not only as the spring base of spring 18 but also can be used as the pressure adjusting of spring 18.
Fig. 1, shown in Figure 3 for another example; Said displacement transducer 8 is fixedly mounted on the said displacement transducer mount pad 6 by screw 9; Said displacement transducer mount pad 6 is provided with corresponding displacement transducer 8 installing holes and wire hole 7, and the displacement chaining pin 11 of said displacement transducer 8 withstands on the shaft of said detection lever 12, for the reliability that detects; The shaft here is designed to a platform, is convenient to displacement chaining pin 11 excellent contact; Said displacement transducer mount pad 6 is fixed on the tubaeform sliver input termination 16 through cover plate 10.
Fig. 1, shown in Figure 3 for another example; Said detection lever manual overvide is located on the said displacement transducer mount pad 8; It comprises button 1, push rod 4, back-moving spring 2 and transition push rod 16, and said push rod 4 upper ends connect button 1, and said back-moving spring 2 is located on the push rod 4; Said push rod 4 lower ends are designed to inclined-plane 15; Said transition push rod 16 is located at inclined-plane 15 and detects on the cover plate 10 between the lever upper end 22, and said transition push rod 16 1 end work withstand on the said inclined-plane 15, and said transition push rod 16 other end work withstand on the upper end 17 of said detection lever.Between said displacement transducer mount pad 6 tops and said button 1, be provided with button stroke positioner; It is made up of stroke spacer 3 and the stopper slot 5 that is located on the button 1; Said stroke spacer 3 lower ends are fixed on displacement transducer mount pad 6 tops, said stroke spacer 3 upper ends and 5 movable connections of stopper slot.
Initial in sliver production, web 25 carries out sliver and wears when expecting after the sliver repiece; Press the button 1, button 1 drives push rod 4 and moves down inclined-plane, push rod lower end 15 roof pressure transition push rods 16; Detect lever upper end 17 by transition push rod 16 roof pressures then, overcome the pressure of spring 18 simultaneously, detect the lever lower end 14 upwards swing of moving axis 23 that rotates; The passage that detects between lever lower end 14 and the sliver outlet plenum is increased, and it is very convenient to make sliver 26 pass sliver input termination 13.After sliver was worn and expected to finish, the pressure of disengage button 1 under the effect of back-moving spring 2, detected the lever manual overvide and restPoses; The detection lever also under the effect of spring 18, restPoses.
When sliver is produced; When the thickness (density) of sliver when changing; Under the acting in conjunction of sliver 26 and spring 18; Detect the lever lower end 14 moving axis 23 upper and lower swings that rotate, the shaft that detects lever is upper and lower to be moved thereby drive, and the displacement chaining pin 11 that touches on the displacement transducer 8 produces detection signals output.The upper and lower mobile distance of shaft varies in size, and the different detection signal that will produce of displacement transducer 8 is exported.
