2, electrical motor 27, axle 32, axle 23, axle 13 and strapping are installed on the frame 16 and carry frid 15.
3, pressing plate 6 is one to be the mobile of rotating shaft with fulcrum shaft 13, and a fulcrum 12 is installed at the middle part of pressing plate 6.Overdrive clutch transmission gear 26, key 41, feed roller 25, bearing 43, bearing 30, axle sleeve 40 and the axle sleeve 42 of overdrive clutch 39 is equipped with in the portion within it of being separately installed with on axle 12, is provided with the circlip 24 of two location usefulness at the two ends of axle 12.The left end of pressing plate 6 is enclosed within on the boosting-rod 5, and tension spring 9 is enclosed within on the boosting-rod 5 that is in pressing plate 6 left ends top, and the two ends of tension spring 9 are lined with 2 packing rings 8 and 10, and afterburning setting nut 11 is installed above packing ring 10.Hang with a pulling force camphor tree spring 4 on the screw 7 of the left end (non-support end) of pressing plate 6, the other end of spring 4 is hooked on the screw 3, and pressing plate 6 is subjected to the pulling force of tension spring 4.Spring 4 pulling force that produces is axle 13 generation moments of fulcrum to pressing plate 6 right-hand members, this moment passes to feed roller 25 through axle 12, add again and be pressed on the strapping, when feed roller 38 is rotated, strapping is driven under the friction force effect, strapping (P) is constantly drawn in by the M end, is sent the trough of belt of frid 15 again from the N end.
4, force transferring lever 21 is that fulcrum is installed on the frame 16 with axle 23, and can rotate around fulcrum shaft 23, one roller shaft 19 is installed on one end of lever 21, being equipped with on 19 at this can be around this 19 reinforced roller 18 of rotating, this roller 18 is positioned on the roller shaft 19 by circlip 20, and the other end of force transferring lever 21 is enclosed within on the boosting-rod 5.
5, boosting-rod 5 is screw rods, and it runs through force transferring lever 21, pressing plate 6 from bottom to top, is on the boosting-rod 5 of pressing plate 6 tops to be with energizing spring 9.

When gear 26 backward rotation, (this moment, strapping P was in the forward (FWD) state), roller 46 is pushed to the big end of tubaeform skewed slot 47, thereby roller 46 and axle 12 are broken away from, though gear 26 is still rotating but axle 12 does not rotate, just can be smaller in forward (FWD) wheel 25 power that are added on the strapping P, because the pulling force of extension spring 4 is determined, when the resistance that advances as strapping P surpasses the pressure that extension spring 4 given, though gear 26 is still rotating under gear 36 drives, but because the effect of power-transfer clutch 39 makes the rotation of gear 26 can't pass to axle 12, so axle 12 does not rotate, feed roller 25 is active rotation (promptly not being power wheel) not also, and the strength that is added in like this on the strapping P just is limited in certain numerical value.Because having only a feed roller 38 is power wheels, when this just made forward (FWD) stop, strapping P did not reach greatly because of impulse force, and causes overshoot, so reduced the appearance of stifled band accident, had created advantageous conditions for next step taut band again simultaneously.
(be in the taut band state this moment) when gear 26 forward rotation, roller 46 is pushed to the small end of skewed slot 47, and axle 12 and overriding clutch 39 is stuck, and both are linked together tightly.When the gear that links to each other with power-transfer clutch 39 26 rotated, axle 12 also rotated with feed roller 25, and feed roller 25 becomes power wheel at this moment.Because two power wheels 25 and 38 are arranged, increased taut band power, tying up tightness increases, and has improved and has tied up the tightness increase, has improved bundling quality.
Mode of operation of the present utility model is following two kinds of situations:
One, when sending band: electrical motor 27 rotations, gear 36 on the main shaft 32 and feed roller 38 are rotated, because power-transfer clutch in-to-in roller 46 is pushed to skewed slot 47 and holds greatly, axle 12 links with 26 disengagings of overdrive clutch transmission gear, feed roller 25 can not become power wheel.Strapping P passes through from the contact surface between two feed rollers 25 and 38, and under the effect of friction force, strapping P is sent the N end through trough of belt 15.When electrical motor 27 stops operating, strapping P also stops to be transferred immediately.
Its two, during taut band:, make switch triggering when being put when tying up platform by the bundle article, electrical motor 27 reverses immediately, and gear 36 driven gears 26 rotate, and this moment, power-transfer clutch 39 in-to-in rollers 46 were pushed to the small end of skewed slot 47, feed roller 25 becomes power wheel, strengthens taut band power, carries out belt tensioner work.Meanwhile, afterburning cam 22 upwards pushes up roller 18, under the effect of lever, force transferring lever 21 left ends move down, drive boosting-rod 5 and also move down, energizing spring 9 produces tension force and passes to feed roller 25 through pressing plate 6, makes feed roller 25 produce bigger pressure and is pressed on the strapping P, further strengthened tightening force, improved and tie up tightness.When tying up end-of-job, enter the forward (FWD) mode of operation again automatically, repeat above-mentioned forward (FWD) work, go round and begin again with this.
So far, technical solution of the present utility model has reached its intended purposes, because it is reasonable in design, and adopted overriding clutch cleverly, not only reached automatic, and solved the problem of sending band overshoot and stifled band, taut band power is increased for band, it ties up Li Keda 70～100N, thereby has improved bundling quality.Also have the work efficiency height, reliable, safeguard characteristics such as easy, and can make tape supply device for any strapper.
