The specific embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the present invention in detail.
shown in Figure 2, a kind of beating-up force endurance control system, it comprises beating-up force sensor 1, beating-up force computational analysis device 2, encoder 3, back rest locking control panel 4 and back rest shaft shoulder locking mechanism 5, described beating-up force computational analysis device 2 comprises the electric bridge signal processor 201 that is electrically connected to successively, signal picker 202, beating-up force calculator 203 and the state judging 204 of beating up, described beating-up force sensor 1 is electrically connected to described electric bridge signal processor 201, described encoder 3 is electrically connected to described signal picker 202, be used for the angle signal of output main shaft gyration to described signal picker 202, the described state judging 204 of beating up is electrically connected to described back rest locking control panel 4, described back rest locking control panel 4 is electrically connected to described back rest shaft shoulder retaining mechanism 5.
Further, described beating-up force sensor 1 comprises four foil gauges, and two grooves are made on the two sides at the middle part of the side shelves of special-shaped reed, and described four foil gauges stick in twos to do in described two grooves and form a bridge.
The beating-up force sensor forms with the side shelves transformation of the way of special-shaped reed.The top and the bottom of former side shelves are constant, and two grooves are made on the two sides in the middle part of the side shelves, paste two foil gauges on each cell wall, paste four foil gauges on two cell walls, and four foil gauges form a bridge.When beating up, the reed groove of special-shaped reed is subject to the active force of fabric, and the power that acts on reed wire passes to the left and right sides shelves by the reed beam, and the foil gauge group sticks on the thin-walled place at side shelves middle part, and the distortion of side shelves has caused elongating or shortening of foil gauge.
Signal is input to signal picker 202 after electric bridge signal processor 201, the angle signal of encoder 3 output main shaft gyrations is to signal picker 202 simultaneously.The process of beating up accounts for the fraction of turn over, account for about 5 degree, so encoder 3 improves the data acquisition amount by signal of 0.2 degree output.
In one group of signal, abscissa is the main shaft gyration angle, and ordinate is beating-up force, generates beating-up force curve and a peak.If contain spike in the measurement curve, the process of beating up is normal; If do not contain spike in the measurement curve, before showing that the process of beating up arrives maximum, the back rest is loosening.Judge whether thus to start locking mechanism.
When beating up, fell reach is born beating-up force this moment mainly by the fixing back rest.When tension force was large especially, fixedly the back rest be can't hold out against, and did not allow the back rest have a bit and rotated.The back rest has withstood, and beats up just can fasten, if the back rest be can't hold out against, fabric is just beaten not tight.
Further, referring to Fig. 3, Fig. 4, Fig. 5 and shown in Figure 6, described back rest shaft shoulder retaining mechanism 5 comprises a fixing back rest 501, the described fixedly back rest 501 two ends are two-period form axle journal 502, the cross section of described two-period form axle journal 502 is divided into two sections, one section cross section is flat 503, and another section cross section is the circle 504 with keyway 505.
Preferably, described cross section is one section axle journal of flat 503 in the outside, and described cross section is one section axle journal with the circle 504 of keyway 505 in the inboard, as Fig. 3.
Preferably, described cross section is one section axle journal of flat 503 in the inboard, and described cross section is one section axle journal with the circle 504 of keyway 505 in the outside, as Fig. 4.
Preferably, the external diameter of the described fixedly back rest 501 is Ф 120-Ф 150mm.
The above is only preferred case study on implementation of the present invention, is not limited to the present invention, and for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
